Frequent consumption of aflatoxins-contaminated spices has been linked to serious adverse health effects among consumers. The likelihood of exposure to these toxins is influenced by the level of public awareness. Controlling aflatoxins contamination throughout the food chain is critical for public health. This study aimed to assess the handling practices and awareness of aflatoxin contamination among micro- and small-scale spice processors. A total of 60 processors from 4 districts of two regions of Tanzania were interviewed. The results showed that while 56.7% of interviewed processors were aware of aflatoxin contamination in spices primarily through training (38.3%) and mass media (30%). However, there were still misconceptions regarding the causes and effects of aflatoxins to human health. It was observed that, poor drying and storage practices, inadequate monitoring of processors aggravated the situation. Nonetheless, all interviewed processors expressed willingness to participate in training programs to ensure quality and safety along the chain. The study findings underscore the necessity for targeted interventions to reduce aflatoxin risks in the spice value chain. These should include strengthened food safety inspections and enforcement, as well as tailored training and support for micro and small-scale spice processors. Enhancing their knowledge and ability to adopt proper handling, drying and storage practices is critical for enhancing food safety and safeguarding public health.

The Relationship Between Lymphocyte Count and Mortality in Patients with Dysphagia

Min Wei, Chengming Ke, Sumin Wu

World Journal of Clinical Medicine Research 2025, 5(1), 40-51. DOI: 10.31586/wjcmr.2025.6128

Abstract Background: Dysphagia is a common functional impairment in elderly populations, often leading to severe complications such as malnutrition and aspiration pneumonia, significantly increasing healthcare burdens. Currently, effective prognostic assessment tools are lacking. The absolute lymphocyte count (ALC), a biomarker reflecting immune-nutritional status, has potential predictive value in this context, though its role in dysphagia prognosis remains unclear. Methods: This retrospective cohort study included 253 dysphagic patients who received percutaneous endoscopic gastrostomy (PEG) or total parenteral nutrition (TPN) between 2014 and 2017. Five patients with missing ALC were excluded. Cox regression models assessed the association between ALC and mortality. ALC was analyzed as both continuous variable (using restriocted cubic splines) and categorical tertiles, with additional threshold analyses to assess non-linearity. Kaplan–Meier survival curves and subgroup analyses were also performed. Results: Lower ALC was associated with poorer nutritional status, higher inflammatory markers, and greater comorbidity burden. Higher ALC was independently associated with reduced mortality (adjusted HR: 0.60; 95% CI: 0.44–0.83; p = 0.002). Patients in the highest tertile had significantly better survival than those in the lowest (HR: 0.37; 95% CI: 0.23–0.59; P < 0.001). A non-linear threshold effect was identified at ALC = 1.899×10⁹/L (p for non-linearity = 0.009). Kaplan–Meier analysis confirmed improved survival with higher ALC (p [...] Read more.

A non-linear threshold effect was identified at ALC = 1.899×10⁹/L (p for non-linearity = 0.009). Kaplan–Meier analysis confirmed improved survival with higher ALC (p < 0.0001). Subgroup analyses showed the protective effect of higher ALC was consistent across age, sex, BMI, PEG use, and comorbidity strata, with no significant interactions. Conclusions: ALC is an independent, non-linear predictor of mortality in older dysphagic patients and may aid clinical risk stratification across diverse patient subgroups.

Objective: To identify and evaluate the main functional assessment tools applied in the postoperative monitoring of patients undergoing total knee arthroplasty (TKA), and to synthesize the functional outcomes reported through these instruments in the current scientific literature. Methodology: A structured review was conducted following PRISMA 2020 guidelines. Thirty-one peer-reviewed studies were selected through a targeted manual search based on predefined eligibility criteria. Included studies evaluated functional recovery following TKA using validated outcome measures such as the WOMAC, KSS, KOOS, IKDC, SF-36, and SANE. Data extraction focused on the instruments used, patient population characteristics, and reported outcomes. A descriptive synthesis was compiled in Table 1. Additionally, 15 studies with quantitative data were analyzed using a forest plot to illustrate risk ratios (RR) and 95% confidence intervals (CI) for functional improvement. Risk of bias was assessed qualitatively based on methodological rigor, clarity of reporting, and validation of the outcome tools. Results: All included studies reported improvements in functional status following TKA. Most risk ratios ranged from 0.66 to 0.85, indicating a consistent reduction in the risk of postoperative functional limitation. High-quality studies demonstrated more precise effect estimates and greater internal validity. The SANE scale emerged as a valid and practical tool with high responsiveness, including in its culturally adapted Brazilian version. Despite heterogeneity in study design, the direction of effect remained consistent across all included studies. Conclusion: Validated functional assessment tools are essential for monitoring recovery after total knee arthroplasty. Instruments such as WOMAC and SANE demonstrate strong clinical utility and psychometric validity. Their systematic use enhances outcome comparability, supports individualized rehabilitation planning, and improves decision-making in orthopedic care.

Objective: The knowledge, attitudes, and practices of SUA students about the use of plastics containing endocrine disruptors were investigated in this study. Methodology: A study with 150 participants was conducted to assess individuals' knowledge about endocrine disruptors, attitudes, and plastic use practices. Results: The findings indicate that the participants possessed an average degree of knowledge 50.2 ± 3.85 with the main emphasis of awareness being generic concepts rather than specific substances. Regarding the potential health impacts of endocrine-disrupting chemicals present in plastics, respondents' attitudes ranged from fair to positive, with a mean score of 3.5 ±0.09 indicating a fair attitude overall. Conclusion: It is important to practice polite behavior and increase public awareness of safe plastic disposal methods. Surprising only 38.0% of the participants mentioned that they refrain from heating their food in plastic containers to reduce their exposure to plastics. Students' practices revealed a notable dependence on plastic products despite their awareness of the concerns surrounding endocrine disruptors, as most of them reported using plastic water bottles, plastic cups, and plastic bags almost always. Additionally, only 20.7% of the respondents consistently implemented strategies to prevent exposure to endocrine-disrupting chemicals. Recommendation: The study recommended increasing the use of cleaner plastic substitutes and improving educational programs to convert information into practical actions. Policies that encourage environmentally friendly behavior and raise public awareness of safe plastic disposal techniques should be put into practice.

Background: Mechanical low back pain (MLBP) is a leading cause of disability worldwide, with well-established risk factors such as obesity, occupational ergonomics, and core muscle strength. However, the role of pes planus (flat foot) as a contributing factor remains underrecognized. This study aims to investigate the association between flat foot and MLBP using Clarke’s angle as an objective measure of foot posture. Methods: A case-control study was conducted in South Timor Tengah Regency, East Nusa Tenggara, Indonesia, from December 2024 to February 2025. Fifty patients diagnosed with MLBP and 50 healthy controls were enrolled. Foot type assessment was performed using Clarke’s angle, with a cutoff of ≤30° indicating flat foot. Pain severity in the LBP group was recorded using the Numerical Rating Scale (NRS). Statistical analysis was conducted using chi-square and independent t-tests, with significance set at p < 0.05. Results: Flat foot was significantly more prevalent in the LBP group (58%) than in the control group (18%) (p = 0.000; OR: 6.29, 95% CI: 2.52-15.69), indicating that individuals with flat feet are over six times more likely to experience MLBP. No significant differences were observed between the groups regarding BMI, age, or gender. Conclusion: These findings suggest that flat foot is an independent risk factor for MLBP, likely due to altered spinal biomechanics and compensatory postural changes. Clinicians should consider foot posture assessments in MLBP patients and explore targeted interventions, such as orthotic support, to mitigate symptoms.

Silver nanoparticles (Ag⁺NPs) contamination in the environment is a serious concern. This study investigated selected heavy metal (Ag⁺, Cd^2+, Cr²⁺ and Pb²⁺) concentrations at different sampling points to assess the risk to human health (infants, children, and adults). To do this, an enclosed area (laboratory) of 12.6 m X 8.5 m (107.1 m²) was clearly marked at different coded distances of S1, S2, S3, and S4 representing 2, 4, 6, and 8 m, while unpolluted atmosphere at 50 m away without Ag⁺NPs served as the control (S5). The silver fireworks were allowed to burn for an approximate 00h03m30s at each sampling points using a high-volume air sampler mounted at the Environmental Engineering Departmental Laboratory, Rivers State University, with windows and doors closed to simulate indoor conditions. Samples were digested using a mixture of analytical-grade nitric acid, analytical-grade hydrochloric acid and analyzed to evaluate the levels of heavy metals by atomic absorption spectrophotometry. The Ag⁺ result at S1 shows 30,000 µg/cm³, S2 was 29,000 µg/cm³, while S3 was 28000 µg/cm³ and then S4 was 13,000 µg/cm³. These results exceeded the permissible values of the United States National Ambient Air Concentration for rural, urban and industrial areas (0.0005, 0.004 and 0.6 µg/cm³, respectively). The result for the control (S5) (0.037 µg/cm³) was within the maximum allowable value. Results from other heavy metals such as Cd were 1000, 743, 401, 153, 0.001 µg/cm³, Cr was 5000, 4000, 3729, 2960, 0.002 µg/cm³, Pb was 0.048, 0.041, 0.035, 0.034 and 0.01, µg/cm³, respectively. However, higher values of Ag⁺, Cd, and Cr indicated a higher propensity for the metals to be toxic (bioavailable). In addition, the assessment of the potential health risk posed by these metals proved contaminated and harmful. Visitors recorded high values in exposure concentration (EC) and low values in average daily dose (ADD).

A diagnosis of the current state of the crops is made regarding the control of weeds, use of pesticides, fungicides; with an assessment of the state of the plant covers in the crop, and its control by different types of herbicides, and we detected a high loss of biological diversity; and some of these compounds are mentioned due to their high toxicity. Similarly, the use of pesticides and fungicides is discussed due to their repercussions on health. In order to avoid the unhealthiness caused by the applications of these products, phytosanitary and educational control strategies are proposed; promoting the inspection of fruit and vegetable markets, and modifying the contents in higher professional and university education. To this end, we propose an active teaching methodology, through which the student acquires skills and responsibility for the use of chemical agents in agriculture, which serves to prevent the entry of these contaminants into the food chain. Of the different polluting chemical agents, in the case of herbicides we highlight Oxyfluorfen and Glyphosate with high toxicity and whose consumption is very high. In the case of pesticides and fungicides, among others are Organochlorine compounds, which have been detected in blood, and Carbon Tetrachloride and Chloroform, considered potent hepatotoxic and neurotoxic. The basic objective of this study is the awareness and acquisition of knowledge by future teachers about polluting agents, which will subsequently have an impact on society.

Background: There is paucity of data on health-related quality of life (HRQoL) among Health Information Managers/Health Record Officers (HROs) in the Nigeria health system. Hence, this study investigated the impact of the COVID-19 pandemic on health-related quality of life (QoL) among HROs in Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), Ile-Ife, Nigeria. Methods: A cross-sectional study was conducted in the University Hospital, where a total of 52 health record officers were purposively sampled. Relevant data were collected using the Short Form survey (SF-36v2) questionnaire. One-way ANOVA was used to determine mean group differences across the nine and the two QoL (physical and mental) summary domains based on respondents’ socio-demographics, while level of significance was set at 0.05. Results: All the QoL sections of the instrument used yielded an α-Cronbach’s score of > 0.70. Analysis of some QoL physical component dimensions showed that; Bodily pain (BP) was found to be significantly (P=0.032) associated with marital status, Physical functioning (PF) with gender (P=0.023), and general health (GH) with age group (P=00.025) and highest level of education (P=0.023). On the other hand, mental health component analysis revealed that Social Functioning (SF) was associated with age group (P=014), Role limitation (RE) with marital status (P=0.048), highest level of education (P=0.048) and years of service (P=0.015) etc. Conclusion: The QoL among HROs studied was generally above average, and demographic characteristics such as age, gender and marital status significantly influence QoL. Health managers and stakeholders should consider some of the factors identified in managing HROs.

Background: The COVID-19 pandemic disrupted routine osteoporosis care due to clinic closures and limited in-person consultations. Telehealth emerged as an alternative model enabling remote care delivery and monitoring. However, previous reviews on telehealth either did not include the pandemic period or had a limited focus in scope. Evidence synthesized specifically for osteoporosis care during the pandemic is needed but lacking. Methods: We systematically searched PubMed, MEDLINE, EMBASE, PsycINFO, Web of Science, and CINAHL for studies on telehealth for osteoporosis published between January 2021 and March 2023. Five studies met the inclusion criteria of: osteoporosis population, telehealth intervention, and COVID-19 pandemic timeframe. Data was extracted on study characteristics, COVID-19 outcomes, osteoporosis status, telehealth purpose, patient satisfaction, and clinical outcomes. Result: The five studies showed telehealth was used for monitoring data, delivering test results, adjusting medications, and assessments. Osteoporosis prevalence among telehealth users ranged 30-100%. High patient satisfaction was reported with telehealth versus in-person care. No major differences occurred in medication delays or fractures between telehealth and in-person groups. Conclusion: This review found telehealth enables effective osteoporosis care and monitoring during the pandemic, with high patient and provider satisfaction. However, more robust randomized controlled trials are needed to establish stronger evidence around telehealth's impacts on clinical osteoporosis outcomes. Implications: Though promising, further high-quality studies will help clarify telehealth's role in improving osteoporosis care and outcomes. Findings inform guidelines on integrating telehealth into routine management. Evidence on user perspectives optimizes telehealth implementation policies.

The government of Mexico City carried out the introduction of palm trees in the 50s to increase the visual appearance of the main avenues. As a result of introduction of these exotic species, phytosanitary problems appeared. Currently there is scarce information on how to evaluate the health of these majestic monocots, in this sense, it is necessary to implement assessment scales to determine the health condition of the most frequently found species to advance on their care and management. The present study had the following objectives: 1) To determine the current state of health of palm trees by means of a scale of visual evaluation of the crown; 2) To know the diversity and structural characteristics of palm trees and 3) To determine the influence of composite variables on the ecosystem services such as the amount of shade provided. Health of palm trees were evaluated two times (dry and rainy seasons in 2022) on 35 transects of 200 m length. An imaginary circle divided into twelfths was overlapped on palm tree “crowns”, and through it, two absolute variables, Live Crown Ratio (LCR) and Crown Quality (CQ) were evaluated. Composite variables were also calculated. The 12/12 health scale adapted in the present study was useful. Four health categories were obtained for the Live crown ratio (LCR): 7.62% of the palm trees were in critical condition, 7.80% were in intermediate condition, 80.36% were in normal condition, and 4.20% were in excellent condition. Meanwhile, for crown quality (CQ), the percentages were 13.50%, 20.00%, 56.96% and 0.43%, respectively. The total height and “crown” diameter showed a positive correlation with the volume composite variables. The shadow area projected as an important ecosystem service increased as the health of the palm trees improved. This is the first study on palm trees health assessment in Mexico City.

The study accessed the critical risk factors in public-private partnership (PPP)-procured mass housing project (MHP) delivery in Nigeria. The research design adopts a quantitative approach, using well-structured questionnaires distributed to stakeholders involved in PPP-MHPs i.e. consultants, in-house professionals, contractors, and the organized private sector (OPS) registered with PPP departments in the Federal Capital Territory Development Authority (FCDA) Abuja, Nigeria. The instrument relates to the background information of respondents and the risk peculiar to PPP-MHP. Sixty-three (63) risk factors were submitted for the respondents to rank using Mean Item score (MIS) for risk occurrence and its severity, while risk significance index (RI) was used to determine the risk impact. Fuzzy Synthetic Evaluation (FSE) method was subsequently applied to determine the risk criticality groups and the overall risk level in the sector. The fuzzy set theory deals with ambiguous, subjective and imprecise judgments peculiar to decision making in construction project risk assessment. It aims to provide a synthetic evaluation of an object relative to a fuzzy decision environment with multiple criteria that requires qualitative linguistic terms. The findings show that thirty-one (31) risk factors were critical in the sector while financial and micro-economic risk group is contributing most significantly to the overall risk level in PPP-MHPs in Nigeria. The top 10 risk factors in the sector include availability of finance, high finance cost, the unstable value of the local currency, lack of creditworthiness, influential economic events (boom/recession), high bidding cost, poor financial market, financial attraction to project investors, interest rate volatility, inflation rate volatility, corruption and lack of respect for the law, non-involvement of the host community and poor execution of housing policies. The implication for practice is that having known the risk group contributing most significantly to the overall risk level in PPP-MHPs, adequate financial and budgetary allocation should be made available before embarking on such venture so as to sustain the scheme in the country. The study is one of the recent researches conducted on housing, since the procurement option is novel in the sector. The study is of immense value to PPP actors in providing necessary information required to formulate risk response methods in minimize the identified risk impact sector.

There have been various concerns about the environmental impact of construction works. This generates a need to take a more proactive approach in evaluating the environmental impacts of construction operations and further explore ways to reduce the environmental impacts. Enormous opportunities exist within the building industry to achieve a reduction in greenhouse gas emissions. The aim of the study is to develop a framework for the evaluation of improvement opportunities for environmental impact for onsite and offsite building construction works using life cycle assessment (LCA) and value-stream-mapping concepts. Various tools for LCA exist; however, there is a need for the development of an LCA framework and improvement opportunities that can be localized to various communities to evaluate improvement opportunities for building construction. This study conducts a review of methods to evaluate the LCA of buildings on local construction sites. A procedure for establishing improvement opportunities is also developed. Based on the author’s knowledge and experience, including site visits, using value stream mapping (VSM) techniques, a conceptual framework of the present state map and future state map of residential construction works was developed. The study presents a procedure for the evaluation of improvement opportunities for the environmental impacts of construction operations.

Life cycle assessment, LCA is one of the tools that is used to measure the environmental impacts of a process or an operation. Various studies have mentioned the benefits of mass timber in building construction. This study presents an evaluation of the LCA of certain mass timber in relation to concrete-based materials. Using Athena impact estimator for buildings, the study compared the results of an LCA study for a house that is designed with concrete beams, concrete columns, and concrete walls with brick in the envelope category (Material group 1) with those that are made with glulam beams, glulam columns, CLT walls with spruce wood bevel siding (Material group 2), and another building with LVL columns, LVL beams, CLT walls with spruce wood bevel siding (Material group 3). The results are in line with those that were reported by the majority of previous researchers. For the location that is being reviewed (Calgary, Alberta), the designs showed that construction with wood materials having mass timber components will have a better environmental performance than that for a building design with more concrete-based materials. The building design with more concrete-based material (group 1) showed 242% and 60% higher global warming and acidification potential respectively than the building with glulam beams and columns (material group 2). Except for ozone depletion potential, material group 2 (with glulam beams and columns) has a lower impact than material group 3 (with LVL/PSL beams and columns). The differences in impacts are more pronounced when the comparison is with design with more concrete-based products. This report further shows that LCA can be helpful during the preliminary design to evaluate the expected environmental impacts of the choice of different materials. This study recommends that material manufacturers and building contractors pay attention to LCA results to evaluate areas for continuous improvement.

Hand hygiene is crucial in preventing healthcare-associated infections. In this study, we aimed to quantify the accuracy of subjective evaluation of hand washing through visual inspection and objective evaluation through images. The participants were 24 consenting nursing students, and the study used black light and fluorescent paint to generate sketches and captured images of the unwashed areas, which were processed. Handwashing training was conducted once a week for four consecutive weeks. We collected data in the first and fourth training sessions. We found that the percentage of the unwashed palmar areas was significantly higher in the images than in the sketches (p<0.05). The percentage of the uncleaned area as recognized visually significantly increased for sketches (p=0.01) and decreased for images (p=0.009) in the fourth session. The difference between the percentages of the image and sketch area notably decreased in the fourth session (p=0.002). When we checked the recognition percentage of the unwashed area by dividing the right-hand palmar side into six areas, the fingertips had the highest percentage, and the ball of the thumb had the lowest percentage. The recognition of the unwashed areas was low when comparing the subjective visual assessment with the objective imagery assessment. In addition, the percentage of the unwashed areas decreased with repeated training, indicating a decrease in the difference between the subjective and objective ratings.

Studies have highlighted the benefits of frequent quizzing in class. Frequent quizzing can promote more student attendance, engagement, practice and review, and achievement. Conversely, the opponents of frequent quizzing suggest that too frequent testing might hinder learning by frustrating anxious students and inhibiting larger units of instructional material. Notably, most studies have used degree examinations to evaluate the impact of quizzes on student learning and performance, yet little is known about whether quizzes can reinforce student performance in the in-course assessments (ICAs) despite ICA importance in student learning. The present study aimed to test the hypothesis that administration of weekly MCQ quizzes can enhance the leaning outcomes and performance of biomedical science students in assessment methods such as essay and oral presentation that can directly measure and provide information about student learning. It was therefore limited to in-course assessments. We found that the performance of the weekly quiz student group is remarkably better than that of the control student group in both the essay and oral presentation ICAs, which are two measures and indicators of student learning, suggesting improved student learning outcomes and performance after administrating weekly MCQ quizzes that also promoted student attendance in classrooms. The findings of this research study have implications for students, teachers, and curriculum designers in higher education.

The focus of this study was to determine the influence of religious literacy and multicultural teaching competence on the teaching self-efficacy of Religious and Moral Education (RME) teachers in public basic schools within the Kumasi Metropolis. The research employed a cross-sectional survey design with a sample of 308 RME teachers selected through the stratified sampling technique from 165 basic schools across 14 circuits. Data were collected using questionnaires and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The findings revealed that religious literacy significantly and positively influenced teachers’ self-efficacy (β = 0.487, p < 0.05), accounting for 23.7% of the variance. Similarly, multicultural teaching competence demonstrated a strong positive effect on teaching self-efficacy (β = 0.711, p < 0.05), explaining 50.6% of the variance. Finally, the study found that religious literacy and multicultural teaching competence together contributed 52.2% to RME teachers' teaching self-efficacy (SD = 0.692, p < 0.05, R² = 0.522). The study recommended that the Ghana Education Service (GES) and the National Council for Curriculum and Assessment (NaCCA) should design and mandate regular in-service training programmes focused specifically on religious literacy for RME teachers. Also, it was recommended that pre-service and in-service training should emphasise awareness of personal biases, deep knowledge of learners’ cultural and religious backgrounds, and practical skills for culturally responsive pedagogy.

This study proposes an integrated approach combining geographic information systems (GIS) and geotechnical analyses to assess the stability of the Oued Ayda mountain lake dam, located in the Siliana Governorate, northwestern Tunisia. The mechanical properties of the embankment and foundation materials were integrated into a Mohr-Coulomb geomechanical model, while the pore water pressure distribution was simulated for various representative hydromechanical scenarios: end of construction, normal operation, rapid drainage, and short- and long-term empty reservoir conditions. The stability analysis, performed using the Morgenstern-Price method with the SLOPE/W software (GeoStudio), reveals high safety factors on the upstream side (SF > 3 in the short term and SF ≥ 2 in the long term), indicating good resistance of this slope to hydraulic and mechanical stresses. Conversely, the results show that the downstream slope exhibits significantly lower safety factors, ranging from 1.335 to 1.338 under long-term conditions, particularly during normal operating and rapid drainage scenarios. These reduced values indicate a high vulnerability of this slope to persistent saturation and adverse hydraulic gradients. In conclusion, although the dam exhibits satisfactory overall stability, the downstream slope remains the most vulnerable area of the structure. The results underscore the need for rigorous management of water level fluctuations and suggest reinforcing the drainage system or implementing targeted stabilization measures to ensure the long-term safety and durability of the structure.

Meigs’ syndrome is a rare triad of a benign ovarian fibroma (or fibroma‑like tumor), ascites, and pleural effusion that resolves after tumor resection. A 53‑year‑old multiparous woman presented with progressive exertional dyspnea and right‑sided pleuritic chest pain. Respiratory and cardiac evaluations were initially unrevealing. Bedside assessment identified mild right basal dullness, and point‑of‑care abdominal ultrasound demonstrated mild free fluid and a solid right adnexal mass. Chest radiography confirmed a small right pleural effusion. Without computed tomography and without diagnostic paracentesis or thoracentesis, Meigs’ syndrome was suspected. The patient underwent laparotomy with total abdominal hysterectomy and bilateral salpingo‑oophorectomy. Histopathology confirmed an ovarian fibroma. Postoperatively, symptoms resolved dramatically, and follow‑up imaging demonstrated complete resolution of the pleural effusion and ascites. This case highlights the importance of considering gynecologic etiologies in unexplained pleural effusion and dyspnea, especially when accompanied by abdominal distension or pelvic pressure.

Background: Adolescence is a critical developmental stage for the emergence of major depressive disorder (MDD). Structural and diffusion neuroimaging studies have highlighted the anterior cingulate cortex (ACC) as a key region implicated in emotion regulation, stress reactivity, and mood processing. However, few studies have examined whether microstructural characteristics of the ACC, reflected by mean diffusivity (MD) within gray matter–white matter (GM–WM) contrast regions, are associated with depression in early adolescence. Objective: To examine whether mean diffusivity (MD) within the GM–WM contrast of the left caudal anterior cingulate cortex (ACC) is associated with a past diagnosis of MDD among adolescents in the Adolescent Brain Cognitive Development (ABCD) Study, after accounting for demographic, socioeconomic, and adversity-related factors. Methods: Data were drawn from adolescents with diffusion MRI–derived mean diffusivity measures and diagnostics. The independent variable was mean diffusivity (MD) of the GM–WM contrast in the left caudal ACC. The primary outcome was past MDD diagnosis based on structured psychiatric assessments. Covariates included age, sex, socioeconomic status (SES), and exposure to adverse childhood experiences (ACEs). Logistic regression models tested the association between ACC MD and past MDD. A secondary model evaluated the relationship between ACC MD and past suicide attempt. Results: Mean diffusivity of the left caudal ACC was associated with the odds of past MDD, independent of age, sex, SES, and adversity exposure. In contrast, ACC mean diffusivity was not associated with a history of suicide attempt. Conclusions: Increased mean diffusivity in the caudal ACC may indicate microstructural alterations associated with depressive vulnerability in adolescence. ACC tissue integrity may serve as a sensitive neural correlate of early-onset depression.

Study selection, data extraction, and quality assessment were carried out independently by two reviewers. Due to the heterogeneity of the included studies, a qualitative synthesis was performed. Results: A total of 32 studies were included. Preventive measures identified in the literature comprised combined antibiotic prophylaxis (cefazolin and gentamicin), multimodal perioperative protocols such as ACERTO, nasal decolonization for Staphylococcus aureus, silver-impregnated dressings, and structured post-discharge surveillance. Treatment strategies included DAIR (Debridement, Antibiotics, and Implant Retention), the DAPRI technique, one-stage and two-stage revision surgeries, muscle flap reconstructions, and protocols without spacers. These interventions were associated with significantly reduced infection rates and improved clinical outcomes when applied appropriately and in accordance with patient-specific factors. Conclusion: Effective prevention and treatment of PJI in total hip arthroplasty require a systematic and evidence-based approach. Integrated protocols—spanning preoperative optimization, meticulous intraoperative techniques, and rigorous postoperative monitoring—have proven effective in reducing infection incidence. In cases of established infection, surgical management must be tailored to the timing of infection, microbial profile, and host conditions. Two-stage revision remains the gold standard for complex infections, while one-stage revision and emerging techniques like DAPRI offer promising results in selected cases. This review contributes to the standardization of clinical practice and supports improved patient outcomes.

Background: Hepatocellular carcinoma (HCC) faces significant challenges in early diagnosis and prognostic assessment, necessitating novel molecular biomarkers. The role of GCN1 in tumorigenesis remains unclear, warranting systematic investigation of its clinical value. Methods: Utilizing multi-omics data from 164 HCC patients in the TCGA database, we comprehensively evaluated the diagnostic and prognostic value of GCN1 through differential expression analysis, Cox proportional hazards regression, and gene set enrichment analysis (GSEA). Results: GCN1 expression was significantly upregulated in tumor tissues (P<0.001), with ROC analysis demonstrating an AUC of 0.921 (95% CI: 0.893-0.950) for discriminating tumor from normal tissue. Clinical correlation analysis revealed that high GCN1 expression significantly associated with advanced T stage (OR=1.941, P=0.002) and AFP levels >400 ng/ml (OR=3.697, P<0.001). Multivariate survival analysis confirmed its independent prognostic value (HR=1.454, P=0.038). Functional analysis indicated GCN1 promotes tumor progression by regulating cell cycle (NES=2.385) and axon guidance (NES=2.307) pathways. Conclusion: This study first elucidates the dual clinical value of GCN1 in HCC, providing a theoretical foundation for developing novel diagnostic biomarkers and prognostic evaluation systems. Future research should validate its molecular mechanisms and explore potential targeted therapies.

Background: Tobacco use remains a major global health concern, and understanding the factors that influence tobacco-related knowledge and support for tobacco control policies is critical for effective development of tobacco control policies that are accepted by the public. Objectives: This study introduces the rationale, design, methodology, and participants of the SMOKES Study (Study of Measurement of Knowledge and Examination of Support for tobacco control policies), which is conducted to evaluate tobacco use, tobacco-related knowledge and attitude, as well as support for tobacco control policies among college and university students. Methods: The SMOKES Study was designed to address significant gaps in literature by focusing on college and university students in a non-Western context. A multi-center, cross-sectional design was employed to collect data from a diverse sample of college and university students across different geographical provinces in Iran. The survey instrument incorporated a range of measures covering socio-demographic characteristics, university-related variables, family tobacco use status, personal tobacco consumption behaviors (including detailed assessments of cigarette, hookah, and electronic cigarette use), and attitudinal as well as knowledge-based assessments related to vaping. Support for tobacco control policies is also measured. Data were collected using an online survey that included self-administered questionnaires, enabling access to a large diverse sample. This study may be used to determine the prevalence of ever and current use of cigarettes, electronic cigarettes, and hookah, as well as examining the correlates of single, dual, and poly-tobacco use. The study also aims to assess the role of social determinants, attitudes, and ethnic/geographic differences in shaping these outcomes. Results: The study sample consisted of 2403 college and university students, including undergraduates enrolled in different academic programs from all faculties and disciplines. Participants were drawn from universities across 15 provinces, and 11 ethnic groups, ensuring a heterogeneous sample with respect to socio-demographic background, ethnicity, and institutional affiliation. This diversity enhances the generalizability of the findings and allows for the exploration of subgroup differences in tobacco use patterns and policy support. Conclusions: The SMOKES Study offers a framework for examining tobacco-related knowledge and the acceptability of tobacco control policies among a key part of the population, being college and university students. By providing detailed insights into the prevalence and correlates of tobacco knowledge, attitude, use, as well as the tobacco control policy support, the study lays the groundwork for tailored public health interventions and more effective tobacco regulation strategies particularly for college campuses in a non-Western setting.

This study investigated the use of digital design as a tool for assessing attitudes among male sex offenders by exploring how artistic expression can reveal complex emotional landscapes related to their crimes. The study utilized digital paintings, a type of digital design that involves creating artwork using digital tools and software. Digital painting tools allowed the researcher to simulate traditional painting techniques, while benefiting from the flexibility and versatility of digital media. It is essential to comprehend and address offenders’ attitudes towards sexual crimes to create prevention and rehabilitation plans that work. The effectiveness of digital paintings that illustrate the consequences of sexual crimes on offender, victim and the offender’s family was examined in this study. The study examined whether exposure to these visual representations could result in a quantifiable decrease in supporting attitudes toward sexual crimes by comparing participants' pre-test and post-test attitudes using the Crime Pics II tool. There is little research on how visual cues can change offenders' attitudes and perceptions, despite the urgent need for creative evaluation techniques in this delicate field. This study adds to the continuing conversation on crime prevention and offender rehabilitation by demonstrating how well digital design can change perceptions of sexual crimes. A total of 61 male convicts of defilement and rape were purposively sampled for the study. The study utilized an art exhibition and Rapid Serial Visual Presentation format to repeatedly display digital paintings to participants aged 18-45. The artwork produced in both monochrome and polychrome schemes and in realist and surrealist styles was designed to elicit immediate emotional and cognitive responses. Qualitative and quantitative analyses of the participants' responses and reflections provided important insights into their attitudes, including sentiments of regret and guilt as well as a sophisticated awareness of the wider effects of their behaviour. Monochrome paintings tended to portray darker emotions, whereas polychrome paintings showed a wider range of emotions, including hope and recognition of the harm done. The findings demonstrate that digital design can effectively support offenders' emotional processing and self-reflection, demonstrating its potential as a helpful tool in rehabilitative and assessment contexts.

Background: The dual use of e-cigarettes and combustible cigarettes poses significant public health concerns due to the compounded risks associated with the use of both products. Understanding the predictors of dual use can inform targeted interventions and tobacco control strategies aimed at reducing nicotine dependence and health risks among adults. Objective: This study aims to identify the sociodemographic predictors of dual use of e-cigarettes and combustible cigarettes among U.S. adults using baseline data from the Population Assessment of Tobacco and Health (PATH) Study. Methods: We analyzed baseline data from the PATH Study, focusing on adult participants who reported the use of both e-cigarettes and combustible cigarettes. Logistic regression models were used to identify the associations between dual use and key sociodemographic variables, including age, gender, race/ethnicity, and education level. Results: The analysis revealed that dual use of e-cigarettes and combustible cigarettes was predominantly observed among young, female, non-Latino, White, and highly educated adults. Younger adults were more likely to engage in dual use compared to older age groups. Females showed higher rates of dual use compared to males. Non-Latino White individuals were more likely to be dual users than individuals from other racial/ethnic backgrounds. Additionally, higher educational attainment was associated with increased dual use, contrary to traditional smoking patterns. Conclusion: The findings highlight specific demographic groups that are at higher risk of dual use of e-cigarettes and combustible cigarettes, particularly younger, highly educated, non-Latino White females. These insights suggest the need for tailored public health interventions that address the unique needs and behaviors of these populations. Future research should explore the underlying motivations and contextual factors contributing to dual use to enhance the effectiveness of tobacco control policies and cessation programs.

Background: Smoking cessation is a crucial public health goal due to its substantial impact on reducing the morbidity and mortality associated with tobacco use. However, significant disparities in smoking cessation success persist across socioeconomic groups in the United States. Objectives: This study aimed to examine differences in smoking cessation rates among daily smokers based on race, ethnicity, and socioeconomic status (SES) using data from the Population Assessment of Tobacco and Health (PATH) study, spanning waves 1 to 6 (eight years). Methods: Longitudinal data from PATH were analyzed, focusing on baseline daily cigarette smokers followed over an eight-year period to assess cessation outcomes. SES was measured by education and poverty status. Successful smoking cessation was defined as sustained abstinence from cigarettes for 12 months or more at the final wave. Logistic regression models identified predictors of successful cessation, adjusting for potential confounders, including age, nicotine dependence, and access to cessation resources. Results: The analysis revealed significant disparities in cessation success across racial, ethnic, and SES groups. Smokers living in poverty and those with lower educational attainment were less likely to achieve cessation success than their counterparts. Race (Black) and ethnicity (Latino) were also significantly associated with lower cessation success. Conclusions: This study highlights the social determinants of smoking cessation success among U.S. adult smokers, with lower success rates observed among those in poverty and with less educational attainment. These findings emphasize the need for targeted interventions that address the unique barriers to cessation faced by low-SES groups. Public health strategies should prioritize equitable access to cessation resources and culturally tailored interventions to reduce these disparities and improve cessation outcomes among all smokers.

Objective: This study aims to investigate the relationship between the presence of chronic medical conditions and cessation among U.S. adults who use combustible tobacco. We hypothesized that having chronic medical conditions would be associated with a higher likelihood of successfully quitting combustible tobacco. Methods: We utilized longitudinal data from the Population Assessment of Tobacco and Health (PATH) Study, using data from Waves 1 to 6. Only current daily smokers were included in our analysis. The independent variable was the number of chronic medical conditions, defined as zero, one, or two or more. The outcome was becoming a former smoker (quitting smoking). Using multivariate regression analyses, we assessed the association between the number of chronic conditions and tobacco cessation over the six waves. We controlled for potential confounding variables, including demographic factors and socioeconomic status. Results: Our analysis revealed a significant association between the number of chronic medical conditions and the likelihood of quitting smoking. Specifically, individuals with two or more chronic conditions exhibited a greater probability of quitting smoking compared to those with no chronic conditions. The results remained significant after adjusting for potential confounders. Conclusions: Multiple chronic medical conditions may act as a catalyst for smoking cessation among U.S. adults. This suggests that the presence of multimorbidity, defined as multiple chronic disease diagnoses, may serve as “teachable moments,” prompting significant health behavior changes. These findings highlight the potential for leveraging chronic disease management and healthcare interventions to promote tobacco cessation, particularly among individuals with multiple chronic conditions.

The population of this study comprises teachers, head teachers and a School Improvement Support Officer (SiSo) in basic schools in the Gumani/Nyanshegu circuit in the Sagnarigu district of the Northern Region. This study adopted multi-sampling methods to select respondents. Random and purposive sampling techniques were used to select the study's 10 basic schools and 83 respondents. The main tools used for the data collection were the questionnaire and interview. The data was analysed using Statistical Package for Social Scientists (SPSS) software version 23 tools. Descriptive Statistical tools such as frequencies were used to gauge the number of occurrences of the studied variables. The qualitative data was also further analysed in line with the research questions to establish patterns of similarities and variations. These were then validated with the quantitative data for any possible contradictions in the findings. The study concludes that people's socio-cultural and religious beliefs and practices affect the teaching of sex education in school. It was observed that sex education could be misconstrued as an encouragement to young people to engage in early sexual promiscuity. Finally, the study concludes that there cannot be effective sex education without the appropriate logistics such as T.L.M.s, syllabus and time allocation for the subject. The study also acknowledges that the availability of these materials must go along with appropriate capacity building for teachers to be well-positioned to teach the subject. It is recommended that Sexuality education should be included in the curricular and academic calendar of basic schools, along with the provision of adequate T.L.M.s and the proper collaboration with appropriate agencies for the effective teaching of the subject. Sex education needs to be given maximum attention, just as any of the life skills subjects, with adequate investment and motivation to both teachers and pupils to ensure a meaningful impact. There should be regular monitoring, supervision, and assessment of the training of teachers and its influence on the teaching of the subject, as well as ensuring that ethical considerations regarding cultural and religious sensitivities and individual privacy issues are upheld.

Intersectionality has significantly enhanced our understanding of how overlapping social identities—such as race, ethnicity, gender, sex, class, and sexual orientation—interact to shape individual experiences. However, despite its theoretical importance, much of the existing literature has relied on qualitative approaches to define and study intersectionality, limiting its application in predictive modeling, comparative analysis, and policy development. This paper introduces the concept of Quantitative Intersectionality Scoring System (QISS), a novel approach that assigns numerical scores to intersecting identities, thereby enabling a more systematic and data-driven analysis of intersectional effects. We argue that QISS can substantially enhance the utility and predictive validity of quantitative models by capturing the complexities of multiple, overlapping social determinants. By presenting concrete examples, such as the varying impacts of socioeconomic mobility on life expectancy among different intersectional groups, we demonstrate how QISS can yield more precise and reliable forecasts. Such a shift would allow policymakers and service providers to dynamically assess economic and health needs, as well as the uncertainties around them, as individuals move through different social and economic contexts. QISS-based models could be more responsive to the complexities of intersecting identities, allowing for a more quantified and nuanced evaluation of policy interventions. We conclude by discussing the challenges of implementing QISS and emphasizing the need for further research to validate these quantifications using robust quantitative methods. Ultimately, adopting QISS has the potential to improve the accuracy of predictive models and the effectiveness of policies aimed at promoting social justice and health equity.

Background: Telomere length is a critical biomarker of cellular aging and overall health. While childhood socioeconomic status (SES) indicators such as education and poverty can have long-lasting effects on biological aging, research has shown contradictory results regarding the impact of adulthood SES on future telomere length, particularly in racially and ethnically diverse individuals. This study investigates the effects of baseline adulthood SES indicators such as education and poverty on telomere length nine years later in women, using data from the Future of Families and Child Wellbeing Study (FFCWS). Methods: We analyzed data from the FFCWS, a longitudinal cohort study. The sample included baseline adulthood SES and follow-up telomere length measure of women (n = 2,421) with varying socioeconomic conditions. Telomere length was measured from saliva samples nine years after the baseline measure of adulthood SES. Education, poverty, and marital status at baseline were assessed. Multivariate linear regression models were used to examine the association between adulthood SES indicators at baseline and future telomere length, controlling for potential confounders. Results: From the total 2,421 women, 675 were Latino White, 1,158 were non-Latino Black, and 588 were non-Latino White. Our findings indicate that for non-Latino White women poverty at certain level, and childbirth weight, and for non-Latino Black maternal age were predictors of telomere lengths nine years later. Conclusion: Poverty at a specific level, maternal age and childbirth weight serve as predictors of telomere lengths nine years later in some women. These findings underscore the importance of socioeconomic factors and early-life influences in understanding telomere dynamics and aging processes among women from varied racial and ethnic backgrounds.

This study investigates the benefits of forgiveness among adolescents in Junior High Schools (JHS) in Bimbilla, Ghana, focusing on the influence of age on the effectiveness of forgiveness interventions. The study adopted a mixed-method experimental design, a purposive selection of eight JHSs within the Nanumba North Municipality, from which 60 adolescents were randomly chosen to participate. The study employed the Enright Forgiveness Inventory, Depression Mood Scale, and Anger Self-Report items to assess participants' emotional states before and after the intervention. The interventions were structured around the REACH model of forgiveness, which included sessions aimed at helping participants identify sources of hurt, understand the concept of forgiveness, and recognise the emotional costs of holding onto grievances. Qualitative data were analysed into themes using an interpretative lens. A two-way Analysis of Covariance (ANCOVA) was used to analyse the data. The findings revealed that exposure to forgiveness therapies significantly reshaped participants' negative emotions, leading to a marked decrease in feelings of anger and depression. Post-intervention assessments indicated that participants developed a more positive outlook towards their offenders, highlighting the transformative power of forgiveness in fostering emotional well-being. The study's results align with previous research, indicating that forgiveness interventions can effectively reduce negative emotional states and promote psychological resilience. The implications of these findings suggest that integrating forgiveness education into school curricula could be beneficial for enhancing the mental health of adolescents. By fostering an environment that encourages forgiveness, educators and mental health professionals can help mitigate the adverse effects of unresolved emotional conflicts, ultimately contributing to healthier interpersonal relationships and improved overall well-being among young individuals.

This study aimed to examine the school facility quality on children's social achievement in Kindergarten in the Yendi Municipality of the Northern Region. The study adopted a mixed-method approach. The study population comprised twenty-five (25) teachers and five (5) head teachers from all kindergarten schools in five circuits in the Yendi municipality. A purposive sampling technique was used to select the study participants. The main instruments for data collection were structured questionnaires and observation checklists. The data were statistically analysed using simple frequencies and percentiles presented on a simple frequency table. The study reveals that inadequate access to essential resources, such as textbooks, teaching and learning materials, and proper classroom environments, adversely affects teacher effectiveness and student engagement. The findings indicate that while some facilities, such as restrooms and playgrounds, are available, many need to be updated or more to meet the needs of the children. To enhance the educational experience for young learners, stakeholders, including the government, educational authorities, and the community, must collaborate to improve the infrastructure and resources available in these schools.

The study aimed to assess the impact of off-season vegetable farming on farmers in the Savelugu Municipality in the Northern Region. The study population consisted of all respondents to off-season vegetable farming in the Savelugu Municipality in the five selected communities in the Northern Region. A purposive sampling technique was used for a sample size of fifty (50) off-season farmers in the selected communities. An interview guide and questionnaire were used to solicit data to conclude the findings. The data derived from the questionnaire were analysed in a step-by-step thematic analysis that included reading the transcriptions several times, coding, generating codes, and reviewing and naming themes. Afterwards, the questionnaire and interview guide responses were transferred into Microsoft Excel under assigned variable names. Descriptive statistics, namely frequency, means, and percentages, were used to analyse the data. Off-season vegetable production technology can be gained by using different agro-climatic regions, maintaining or adjusting planting time, selecting varieties, and creating artificial and controlled environments through tunnels, polytene houses, glass houses, hotbeds, etc. Moreover, Off-Season vegetables helped earn income and ranked highest with an overall mean score of 1. Nearly all the trained farmers said their primary constraint was the high incidence of pests and diseases. It is evident that off-season cultivation is profitable and significantly impacts the farmers' consumption expenditure and food security status. Therefore, providing improved and modern agricultural inputs to off-season farmers is essential for rural agricultural development.

The control of processes is made smooth and effective by Programmable Logic Controllers (PLCs), which are essential to industrial automation. The assessment of PLCs' reliability is crucial since more and more sectors depend on them for crucial tasks. In-depth reviews of the components necessary to evaluate PLC system reliability are presented in this study. To ensure a robust review, the review first clarifies the basic concepts of reliability, highlighting the significance of system uptime and the ramifications of failures in industrial settings. Next, it examined the different elements that go into a PLC's overall reliability, such as availability, testability, and (maintenance and maintainability). The percentage of the reviewed papers that employed (maintenance and maintainability), testability, or availability to improve the reliability of PLC systems showed that, availability and (maintenance and maintainability) has been employed the most for enhancing system reliability, accounting for 32% each of publications analyzed, followed by testability, accounting for 28% respectively. The scatter chart that depicts the progression of reliability components from 2010 to 2023 also explained that the use of availability and (maintenance and maintainability) was increasing. This upward trend can be explained by the fact that repairable systems are heavily reliant on availability, whereas (maintenance and maintainability) tend to avoid unnecessary equipment breakdown and testability, which ensures the ease with which the functionality of any system or component can be ascertained with the required level of precision.

This study aimed to evaluate the Social Studies Curriculum for Senior High Schools in Ghana to determine whether the subject has attained its goal(s) or not, using Stake’s Countenance Evaluation Model. The study took place in the Asante Akim North District. The population for study were all Social Studies teachers and students in the district. The multi-stage sampling technique was adopted for the study and the sample size was 120, made up of 100 students and 20 teachers. The concurrent mixed method approach was adopted. The main instruments used for collecting data were questionnaires, interviews (focus group and unstructured interview), observation and documentary analysis. Quantitative data were tabulated, organised, analysed and interpreted to draw sound conclusions and generalisations. The data were presented in the form of tables and percentages. Words were used to interpret the tables and percentages for easy understanding. The qualitative data responses were described and explained in the form of themes. Sometimes responses were quoted verbatim to authenticate claims made. The study looked at the congruence between what was intended to occur and what was observed before and during the implementation of the curriculum in the Asante Akim North District. On the transactions, it was revealed that teachers in the district communicate the problem the topic seeks to address and the specific objectives to the learners during instruction. Also, teachers varied their teaching methods, techniques and strategies. However, teachers failed to take students out on field trips. Also, they failed to use video documentaries to deliver their lessons inhibiting students’ creativity as they are denied the opportunity to explore and get first-hand information to build up knowledge and develop the needed attitudes and values. From the findings, it is therefore recommended that the National Council for Curriculum and Assessment should increase the time allotted to the teaching of Social Studies at the SHS level from 3-periods of 40 minutes a week to 5-periods of 40 minutes a week to give teachers and learners ample time to discuss, debate, digest and solve problems during instructional hours to enable the goal of the subject attained.

Qualitatively, the study focused constructivist research paradigm. A case study research design was adopted for the study. The study population comprised all six (6) Social Studies teachers, the headmaster and the School Improvement Support Officer (SISO). Purposive and convenient sampling techniques were used to select the participants for the study. The main instrument for data collection was a semi-structured interview guide and observation protocol. The data were analysed using the interpretative technique based on the themes arrived at during the data collection from the semi-structured interview. The study revealed that multimedia usage is a quality enhancer in educational settings for teaching Social Studies concepts. It also indicated that teachers perceived their incompetence when using technology as they feel less in control of their classes and are unlikely to explore new possibilities that utilise technology when planning their lessons. They learn the theoretical aspect and practice and perceive the teacher’s role in the classroom changes from an instructor to a facilitator, which changes the teaching method to student-centred (constructive methodology) which aids content absorption by the learner through learning by doing. The study also indicated that teachers perceived their incompetence when using technology as they felt less in control of their classes and were unlikely to explore new possibilities that utilised technology when planning their lessons. It is recommended that the Ministry of Education and National Teaching Council collaborate with Ghana Education Service to set up Social Studies training centres in all the district capitals equipped with competent staff to periodically organise in-service training for teachers to build their capacity on how to pedagogically incorporate multimedia resources in their instructions to improve students learning outcomes.

Challenges are part and parcel of human activities. Quantitatively, a relational survey model research was adopted for the study. The population for this study comprised all Junior High School (JHS) Religious and Moral Education (RME) students in Bokro M/A JHS and the Eziom Methodist JHS in the Nzema-East Municipality of the Western Region. Purposive and random sampling techniques were used to select the schools and respondents for the study. The main instruments for data collection were a test and a questionnaire. The data from both the control and experimental groups on the challenges learners face in using the flipped classroom model in RME were analysed using means and standard deviations. The study indicates the challenges learners face by employing the flipped classroom model to learn include lack of data to access the internet, frequent light outs, lack of technological devices to access contents, frequent power outages, and difficulty in comprehending some of the materials given to them. Given that learners face frequent power outages during periods that they watch videos assigned to them by their teachers, it is recommended that the government and the Electricity Company of Ghana ensure that there is a constant flow of power to allow learners trying to use the flipped classroom to learn are without any hindrance. It is also recommended that the Ghana education service should organise continuing professional development for RME teachers on effective uses of technology in teaching and learning subject concepts. The government should also supply the basic schools with all the needed technological devices to promote effective teaching, learning and assessment.

The debate on culture clash necessitates a theoretical framework, and three perspectives that merit attention are homogenization, polarization, and hybridization theories. These intersecting paths lead to the hypothesis that all civilizations could assimilate into the Western model as it is currently conceived. Culture clash is approached from multiple angles due to the widely held belief that rejecting culturally novel concepts is unethical. However, imposing new rules and customs will inevitably encounter innate resistance, as evidenced by numerous examples. The exchange of behavioral models does exist, with one of globalization's main tenets being the universality of values – including the uprooting of what we refer to as primitive manners. Nevertheless, anthropology and cultural research have witnessed intergenerational and long-term survival of elements that contemporary civilization believed it had overcome or at least suppressed deep within the subconscious mind. This article will offer an essayistic approach to certain forms of culture clash.

The purpose of this study was to assess the structural attributes of black and white Printed Printex Textile Fabrics in Ghana. The study adopted a factorial experimental research design. The three fabrics with black prints and white as base colours were purchased from the market. These three fabrics had the same designs but two had different fabric finishes and the third one had no finish (plain, embossed and plisse). Key soap purchased from the Ghanaian market and standard soap from Ghana Standard Authority were used for the study. A purposive sampling procedure was used in choosing the fabrics and soap for the study. Specimens totalling 219 were cut randomly from along the warp and weft directions of the Printex black and white cotton fabric with finishes (plain, embossed and plisse). The use of laboratory experiments and the apparatus used to experiment. The data obtained were presented using both descriptive and inferential statistics. The descriptive statistics (frequencies, percentages, means and standard deviation) were used as summary statistics of variables of the study. The one-way analysis of variance (ANOVA) was used to test for significant differences among three variables (three washing cycles), whereas the independent samples t-test was used to test for statistically significant differences between the performance of the fabric finishes under Key soap and the standard soap. The study indicated that differences in the attributes of the finishes caused differences in the structural attributes of the fabrics. This was because some of the finishes required certain structural attributes to bond well with the fabrics. The implication is that continuous washing weakens the structural attributes of fabrics which causes them to fail or weakens their resistance to stress tests. The study, however, found that differences in the structural attributes of the fabric finishes caused differences in the effects of washing on the selected fabric finishes. It is recommended that Printex Textile Limited should place critical emphasis on the weight of the fibres used in the construction of the fabrics. This was necessary since the study found that the fabric finish with the greatest weight performed better in tensile strength than those with the lowest weight. As a result, the use of fibres with high weight is expected to improve the use and care of the fabric finishes in terms of their ability to resist stress or tension during washing.

An Assessment of Insect Fauna on Staminate and Pistillate Flowers of Cocos nucifera: A Case of Asebu in the Central Region of Ghana

Emmanuel Sylvanus Aidoo, Millicent Gyesi

Open Journal of Agricultural Research 2023, 3(1), 42-57. DOI: 10.31586/ojar.2023.814

Abstract Quantitatively, this study aimed to determine the abundance and diversity of the insect fauna that visits the staminate and pistillate flowers of Cocos nucifera. The study was conducted at an experimental plantation belonging to the Coconut Research Programme (CRP) of the Oil Palm Research Institute (OPRI) of the Council for Scientific and Industrial Research (CSIR), to provide diagnostic support for the Cape St. Paul Wilt Disease (CSPWD) at Asebu in the Central Region of Ghana. The populations of coconut palms represented the dwarf type with few tall ecotypes. Five Insects were randomly chosen with newly opened inflorescences. Observations and collections of insect visitors to coconut flowers were made once a week on 30 newly opened inflorescences, five from each batch within the plantation. Specimens of the data were deposited in the official insect collection and processed at the laboratory of the Entomology Museum of the Department of Conservation Biology and Entomology, University of Cape Coast, Ghana. The study indicated that 9 different species of insects were identified to be the true fauna that visited the staminate and pistillate flowers of C. nucifera Ethiosciapus sp., Sarcophaga sp., Scolia dubia, Lucilia sp., Ornidia sp., Apis melifera, Dactylurina standingeri, Red Ant and Black Ant. These insects were observed in all the six batches considered and were available at all times of the day. Most of the insects were observed in the early morning from 6 am - 9 am followed by the evening 4 pm –7 pm. The abundance of insect visitors was low during the mid-day (11 a.m. to 3 p.m.) in all six batches during high temperatures. The results of this study revealed that there were abundances of Ethioscipus sp. was the least abundant in all the batches followed by Scolia dubia then Sarcophaga sp. Red Ants had the highest abundance in most of the Batches thus becoming the most abundant insect that forage the coconut inflorescence at the Asebu plantation. The bees, Apis melifera and Dactylurina standingeri were the most abundant species after the Red Ants. All these groups of insects were not considered in the study and it is recommended that further studies consider such visitors to observe which insects are doing what on the inflorescence. The range for the ‘time of day for’ of the study was mostly diurnal (morning 6 am-9 am, afternoon 11 am-2 pm and evening 4 pm7 pm).

Quantitatively, this study aimed to determine the abundance and diversity of the insect fauna that visits the staminate and pistillate flowers of Cocos nucifera. The study was conducted at an experimental plantation belonging to the Coconut Research Programme (CRP) of the Oil Palm Research Institute (OPRI) of the Council for Scientific and Industrial Research (CSIR), to provide diagnostic support for the Cape St. Paul Wilt Disease (CSPWD) at Asebu in the Central Region of Ghana. The populations of coconut palms represented the dwarf type with few tall ecotypes. Five Insects were randomly chosen with newly opened inflorescences. Observations and collections of insect visitors to coconut flowers were made once a week on 30 newly opened inflorescences, five from each batch within the plantation. Specimens of the data were deposited in the official insect collection and processed at the laboratory of the Entomology Museum of the Department of Conservation Biology and Entomology, University of Cape Coast, Ghana. The study indicated that 9 different species of insects were identified to be the true fauna that visited the staminate and pistillate flowers of C. nucifera Ethiosciapus sp., Sarcophaga sp., Scolia dubia, Lucilia sp., Ornidia sp., Apis melifera, Dactylurina standingeri, Red Ant and Black Ant. These insects were observed in all the six batches considered and were available at all times of the day. Most of the insects were observed in the early morning from 6 am - 9 am followed by the evening 4 pm –7 pm. The abundance of insect visitors was low during the mid-day (11 a.m. to 3 p.m.) in all six batches during high temperatures. The results of this study revealed that there were abundances of Ethioscipus sp. was the least abundant in all the batches followed by Scolia dubia then Sarcophaga sp. Red Ants had the highest abundance in most of the Batches thus becoming the most abundant insect that forage the coconut inflorescence at the Asebu plantation. The bees, Apis melifera and Dactylurina standingeri were the most abundant species after the Red Ants. All these groups of insects were not considered in the study and it is recommended that further studies consider such visitors to observe which insects are doing what on the inflorescence. The range for the ‘time of day for’ of the study was mostly diurnal (morning 6 am-9 am, afternoon 11 am-2 pm and evening 4 pm7 pm). There was no observation made of the pollination system or activities of these insect visitors nocturnally. There may be high pollination activities of these insects during the late evenings. It is recommended that future work should incorporate the late evening period to observe an abundance of diurnal insect visitors of the coconut inflorescences.Keywords: Insect, Fauna, Staminate, Pistillate Flowers, Cocos nucifera

The purpose of this study was to examine the challenges and management supports in teaching and learning of Social Studies in Public Senior High Schools in Akuapem South and North Districts in the Eastern Region of Ghana. Quantitatively, the study adopted a cross-sectional survey using a descriptive correlational research design to assess Challenges and Management Supports Teaching and Learning of Social Studies in Public Senior High Schools of Ghana. The population of the study comprised social studies teachers and students in the Akuapem South and Akuapem North Districts of the Eastern Region of Ghana. Purpose and probabilistic sampling procedures were used to select senior high schools, teachers and students for the study. The main instrument for data collection was a structured questionnaire (SQ). Data was collected from 261 final year students from five Senior High Schools and 33 Social Studies teachers using structured questionnaire. Data was analysed using SPSS Version 24. Descriptive statistics (mean, SD) was conducted to summarise the data and t-test was applied to establish if there is a statistically significant difference in the perceptions of students and teachers on the school-based drivers and effective teaching and learning of social studies. The results of the study revealed that the key school-based drivers influencing the teaching and learning of social studies in the two districts relate to classroom environment; lack of management supports in terms of resource provision for practical lessons, lack of supportive physical environment such as large class size (t = 32.881, mean difference = 6.2422, p<0.05)- thus preventing teachers from engaging students in practical work and individualising their assignments (t-statistics=37.563, mean difference= 3.0920, p<0.05); and teachers inability to use diagnostics assessment tools to unraveled students difficulties and support them. The conclusion is that, the key drivers influencing effective teaching and learning of social studies are school-based and policy driven. The study therefore recommends that the government should support the teaching of Social Studies through provision of adequate resources to help teachers improve their output. Again, the student-teacher ratio should be reduced.

The emphasis on adapting learner-centric education and inclusive pedagogies to promote learning effectiveness is part of the paradigm shift in teaching. By maximizing variability, differentiated education methodologies ensure individualized instruction and equal academic success for all students. Based on this justification, this study sought to investigate Ghanaian pre-tertiary teachers' adaption of differentiated instruction strategies during the teaching and learning processes. Pre-tertiary teachers within the Kwahu Ridge of the Eastern Region of Ghana were sampled to respond to the close-ended questionnaire. A multi-pronged approach was employed in the data analysis. Respondents possessed knowledge of the differentiated instruction strategies, however, there were some disparities between first and second-cycle teachers. Significant factors influenced the range of diversity in the classroom and knowledge and experience, with the latter showing an unexpected negative influence, possibly due to experienced teachers' preference for traditional methods of teaching. Notwithstanding, a perfect alignment of instructional techniques, activities and assessment practices to accommodate the heterogeneity of students stimulate active participation, interest and readiness to learn. It is recommended that educational stakeholders should recognize the dynamic nature of the learning environment and better provide pre-tertiary teachers with the tools and support needed to employ differentiated instruction techniques successfully to ensure inclusive, individualized and intensive instruction in the classroom.

The purpose of this study was to examine coping strategies for managing the effects of work-family conflict on the management staff of hotels in the Accra metropolis of Ghana. The study adopted a Convergent parallel mixed methods research technique. The population of the study is all-star-rated management staff of star-rated hotels in the Accra metropolis. multi-stage sampling. The estimation of the sample size for the hotel managers was based on Krejcie and Morgan’s table for the determination of the sample size for a given population. The population of 100 managers were stratified and randomly sampled out of the 182 managers. The main instruments for data collection were questionnaires and an interview. Statistical Package for Social Sciences (SPSS) version 22.0 was used to determine simple percentages and frequencies of responses. Pearson product-moment Correlation and structural equation model were used to determine the consequences of work-family conflict as well as coping strategies adopted by managers. Amos PLS was used to determine the moderating effect of coping strategies on work-family conflict and job performance. Hotel managers in the Accra metropolis combine the strategies of structural role redefinition, personal role redefinition, cognitive restructuring and reactive role redefinition to curb work-family conflict. The study demonstrated a positive relationship between coping strategies and job performance. Coping strategies had a moderating effect on the relationship between work-family conflict and the job performance of hotel managers. Thus, to improve the job performance of hotel managers, there should be the application of coping interventions to help them perform on the job. The study also determined that work-family conflict had a significant positive relationship with job performance. Similarly, the study established that coping strategies significantly moderate the relationship between work-family conflict and job performance among hotel managers in the Accra metropolis. Although coping strategies were employed by hotel managers in the Accra metropolis, it is recommended that training sessions on the use of coping strategies and stress management techniques should be considered by management to address psychological and emotional work environment stressors since they have been proven to reduce stress and WFC. It is also recommended that there should be an inter-hotel collaboration to offer smaller hotels which do not have the resources some leverage the impact of work-family conflict. This platform can be provided by the Ghana hotels association to impact knowledge of coping strategies in smaller hotels. The government must be encouraged to liaise with the Ghana hotels association to enforce the mandatory eight-hour work per day to avoid overworking of hotel managers.

The purpose of this study was to use an activity-based method to enhance the teaching and learning of Redox reactions among senior high school learners at Christ the King at Obuasi in the Ashanti Region, Ghana. Quantitatively, the study employed an action research design. The population of the study comprised all final-year elective chemistry students of Christ the King Senior High School (CKC) in the Ashanti region of Ghana. A purposive sampling technique was used to select thirty-five (35). The instruments used in the study were tested. Percentages of students who responded correctly to the pre-test items were compared to percentages of students who responded correctly to the post-test items. The pre-test and post-test mean scores were compared to see if there was any difference in their mean scores. The use of an activity-based teaching method in teaching chemistry appears to be used effectively in imparting the content knowledge of chemistry to students to become successful in their learning. Regarding the benefits of the activity-based method. The use of activity-based teaching methods in redox reaction motivates students to be self-learners and improves performance. It is also evident from the findings of this study that the use of the activity-based method of teaching could enhance student performance in a redox reaction. It is recommended that activity-based methods of teaching should be encouraged to be used by chemistry teachers in the Senior High Schools of Ghana in teaching redox reaction concepts to enhance students’ performance in redox reactions. It is also recommended that the Ghana education service should collaborate with the chemistry teachers’ Association of Ghana to organize professional development programs, seminars, and workshops for chemistry teachers on activity-based to improve their knowledge of teaching skills.

The purpose of this study was to examine teachers’ knowledge base in community resources used in assessing Social Studies concepts in the University of Education Practice Junior High School (JHS), Winneba. The case study design was employed as the study's qualitative methodology. The population comprised two Social Studies teachers in the University Practice JHS, Winneba. Purposive and convenient sampling techniques were used to select the teachers and school for the study. The main instrument for data collection was the interview guide. The two teachers were interviewed because they were in a position to give all the relevant information required for the research. They were also readily available at the time of the research. The study revealed that even though the Social Studies teachers were aware of community resources, they did not involve them often in their lesson delivery. However, in the only case where a teacher took the learners round the school compound to look at the various types of rocks, the learners were excited and willing to learn. The assessment results also showed that almost all learners, both low and high achievers had high scores. Evidence from the inquiry also shows that teachers used only traditional forms of assessment in Social Studies. Teachers give multiple choice and essay type of assessment items to learners. Teachers did not involve community resources in the assessment of Social Studies concepts because of challenges like inadequate time allocated for the teaching of the subject, financial constraints, bureaucratic processes involved in obtaining permission and the need to meet the requirements of external examinations. It is recommended that the Ghana Education Service (GES) should design appropriate policies to ensure that provision is made in the school academic calendar for field trips and community resource engagement for Social Studies education. Social Studies teachers should also be trained on the full range of assessment techniques suggested in the 2012 syllabus. Emphasis should be laid on authentic/alternate assessment practices. At the school level, heads of Social Studies department should organise periodic in-service training for the teachers to ensure that the curriculum, instruction and assessment practices are aligned to ensure that the subject attains its intended goals and outcomes.

Assessment is a vital aspect of curriculum practice. The study adopted explanatory mixed-method approach and sequential research design. The population for the study comprised all Social Studies teachers in Junior High Schools in the Ayensuano District. Convenient sampling techniques and census method were used to select the district, and all the one hundred and twenty-seven (127) teachers who teach Social Studies in the junior high schools in the district. The main instruments used for data collection and analysis were questionnaire and interview guide. The quantitative data was analysed both descriptive and inferential statistical tools. The qualitative data was transliterated and coded based on themes. Pre-set themes were used to generate the transcript (text) data based upon the research questions and discussed. The study concluded that authentic assessment practices by Social Studies teachers included the occasional guidance they give to their students about how to interpret topics and situations into relevant tasks with a clearly defined goal, and how to relate their knowledge in practical challenges. The study also revealed that refined essays, oral presentations, interviews, case study discussions, and live performances as authentic assessment strategies or tools Social Studies teachers used in assessing their students' learning outcomes in lessons. The study indicated that large class size, traditional assessment (examination) system, insufficient logistics and infrastructure, a paucity of funds to begin various activities and programs, a lack of motivation from school administrators, time constraints and difficulty in developing some authentic assessment tasks coupled with assessing some lessons using authentic assessment method are some of the criteria that influence the effectiveness of authentic assessment execution in teaching Social Studies courses. It is recommended that educational leaders should provide the resources to motivate Social Studies teachers to use authentic assessments for students’ learning in the classroom situation. It is also recommended that, Colleges of Education, Universities and National Teaching Council should organise professional development workshops and seminars to build the capacity of trained Social Studies teachers on the effective uses of authentic assessment practices.

Effective Inclusive education experiences can be built through structured interventions. The purpose of the study was to assess the impact of inclusive education experiences on teacher-trainees with sensory impairment in the Ghana Colleges of Educations of Ghana. The study was based on pragmatist philosophy. The study adopted convergent parallel mixed-methods approach. The population involved all 66 students with sensory (visual and hearing) impaired in the three (3) CoEs (PCE, Akropong Akwapim, WESCO, Kumasi and NJA, Wa) that practice inclusive education (IE) during the 2018/19 academic year. Purposive and census sampling techniques were used to select the three (3) colleges of education and sixty-six students for the study. The main instruments for data collection were questionnaire and focus group discussion. The quantitative data items were coded for input into the Statistical Product and Service Solutions (SPSS) version 23 software and analysed using means and standard deviations. The qualitative extracts collected into themes that were coded, analysed and interpreted. The study revealed that teacher-trainees had varied experiences on campus, while they felt welcomed into the inclusive institution; they also felt the Colleges were not well prepared to meet their needs. The physical environment was not conducive for the VI on campus. It is recommended that, College authorities should work with the MoE and agencies concerned with disability issues in the society to provide comfortable environment on College campuses for TTSI. It is also recommended that, providing a comfortable environment should include facilities and resources needed for the TTSI to learn effectively. It also involves physical arrangement of the campus environment. The TTSI, regardless of their disabilities, should be provided with an environment where their movement, their studies, their interactions with their peers and tutors are made easier to help them graduate successfully.

Exercise is an important factor of rehabilitation in heart failure patients, improving several indicators of disease prognosis and functional capacity. The aim of the present study was to examine the effect of a cardiorespiratory rehabilitation program on the physical and mental fatigue, general health and anxiety in patients suffering from heart failure. Thirty-one patients with heart failure [(M±SD) age: 67.59±7.60 years] participated in a cardiorespiratory rehabilitation program. The program included aerobic exercise on cycle ergometers and muscle strengthening for 3 months (12 weeks), 3 times/week. Before and after the program, patients' fatigue, general and mental health were assessed using the following self-reported questionnaires: a) Fatigue Assessment Scale (FAS), b) Goldberg's General Health Questionnaire (GHQ-28) and c) Spielberger's Anxiety Questionnaire. Data analysis showed a statistically significant tendency of reduction in social dysfunction (from 1.99±0.42 to 1.75±0.45, p=0.05), while anxiety (from 27.10±7.61 to 26.40±4.35) showed no change (p>0.05).Also, evaluating the changes in the health level after attending the program, there was a trend of improvement in physical activity and functioning with the appearance of fewer physical symptoms (from 1.38±0.43 to 1.24±0.31, p=0,13). These results show that exercise can contribute to increasing the general well-being of these patients and reducing feelings of helplessness, making them able to cope with their daily activities and tasks.

Methamphetamine and its metabolite amphetamine are frequently abused drugs. Whether obtained legally or from clandestine laboratories it is of relevance to determine the chiral makeup of these drugs for investigative purpose. Although urine and oral fluid matrices are commonly offered, less available to independent laboratories are techniques to verify dextro (D-) or levo (L-) (meth)amphetamine from human K2EDTA plasma. This paper outlines the development and validation of a method that includes the addition of internal standard and a two-step liquid-liquid extraction to remove the analytes from human K2EDTA plasma by triple quadrupole mass spectrometry (LC-MS/MS). The assay was validated according to the United States Food and Drug Administration and College of American Pathologists guidelines, including assessment of the following parameters in plasma validation samples: linear range, limit of detection, lower limit of quantitation, matrix effects, inter- and intra-day assay precision and accuracy, carry over, linearity of dilution, matrix effects and stability. The outcome is a validated and reliable method for the determination of D- and L- isomer concentration of meth(amphetamine) human plasma samples that can be easily adopted by independent clinical laboratories.

The study investigated formative assessment conceptions and practices among the teachers of social studies in the Techiman Municipality of the Bono East Region of Ghana. The research was undertaken with the view of finding answers and making suggestions that could help improve the formative assessment practices specifically in social studies. A census was conducted in the eighty-four (84) public Junior High Schools in the Techiman Municipality in the Bono East Region. All the ninety-five (95) Social Studies teachers in the public Junior High Schools in the Municipality were selected for the study. A 50-item questionnaire including 2 open-ended questions was developed for the teachers. The data collected were analysed by using frequencies, percentages, mean and standard deviation. The study revealed that, the teachers had correct conception of formative assessment and saw its relevance in the classroom, however, their assessment practices were not formative enough. The teachers’ assessment practices were influenced by external factors. It is recommended that pressures such as demand for continuous assessment marks to grade students ought to be reduced to allow the teachers practice assessment as professionals.

The study examined consumers’ Awareness in food hygiene and food borne diseases in Koforidua in the Eastern Region of Ghana. The research design for the study was a descriptive survey. The population of the study consists of one hundred (100) consumers. Convenience sampling technique was used to select seventy (70) consumers from the licensed food vendors and thirty (30) consumers from the unlicensed food vendors. Questionnaire was the main instrument for the study. The questionnaire had both open ended and close ended questions was on the consumers’ knowledge and perceptions on food borne diseases and the safety of foods. Data gathered checked, edited, coded, processed and analysed using the Statistical Package for Social Sciences (SPSS) version 17. The study concluded that the consumers of vended foods have some knowledge of food hygiene and food borne diseases; however, they ignore the health hazards associated with poor food handling by food vendors and go ahead to patronize the food the vendors provide. The study also indicated consumers patronized street foods because prices were moderate as compared to the formal establishments and ignore the unhygienic conditions at the vending sites. The correlation analysis shows further that consumers patronage (r=-0.095) had negative and non-significant relationship with food handling practices. It is recommended that Consumers of vended foods should be educated to help improve upon their knowledge in food hygiene and food borne diseases to enable them make informed choices and also prompt regulatory bodies such as the environmental health officers on unacceptable food handling practices of food vendors. It is also recommended The Metropolitan/Municipal/District environmental health officers should ensure that inspection of street food vendors are carried out effectively, efficiently and regularly so as to monitor the food handling practices of the food vendors’ right from the time of preparation to the point of sale.

The purpose of this study was to assess safety conditions of learners in Kindergarten schools in Komenda Edina Eguafo Abirem (K.E.E.A) Municipality in the Central Region of Ghana. The qualitative research approach and the Instrumental Case Study Design were adopted for the study. The population of the study comprised public kindergarten teachers and schools in Komenda Edina Eguafo Abirem municipality in the Central Region of Ghana. Convenient and purposive sampling techniques were used to select sixteen (16) public kindergarten teachers and eight (8) kindergarten schools for the study. The semi-structured interview and observation checklist were the instruments utilized in the data collection for this study. The data were analysed and interpreted thematically using online qualitative software, Taguette version 1.3. The study indicated that, most kindergarten school buildings in the KEEA municipality pose threats to both learners and teachers as result of over-aged or poorly constructed buildings and isolated and bushy environment which attracts animals like lizards, wall geckos and poisonous snakes and psychological and emotional threat to both teachers and learners. It is recommended that, the Ministry of Education in collaboration with the Ghana Education Service should set up a School Supervision for Safety Department (SSSD) to control and oversee safety issues in the kindergarten schools in Ghana. The School Supervision for Safety Department should create awareness advocacy for school safety so that school safety becomes a nationwide concern. It is also recommended that, the School Supervision for Safety Department must liaise with other stakeholders to enforce frequent assessment of school buildings, infrastructure and materials for safety.

Global Journal of Orthopedics 2022, 1(1), 11-23. DOI: 10.31586/gjo.2022.430

Abstract Background: Multiple epiphyseal dysplasia (MED) a rare form of skeletal dysplasia with early-onset osteoarthritis affecting the hip and knee joints. There is paucity of evidence regarding the long term outcomes of arthroplasty in this patient cohort. This is the first study to describe the outcomes of bilateral arthroplasty of the hip and knee in patients with MED. Methods: A prospective study of patients with MED who underwent bilateral staged total hip arthroplasty (THA) and bilateral simultaneous total knee arthroplasty (TKA) between July 2013 to April 2014. Preoperative and postoperative clinical and radiographic assessment including functional outcomes namely Merle d’aubigne score, Harris hip score (HHS), Knee society score (KSS) and numeric rating scale (NRS) for pain were recorded in prospective database and evaluated. Results: 3 patients (female - 1 / male - 2) with MED who underwent bilateral lower limb arthroplasty of the hip and knee were reviewed periodically with an average followup of 7.31 years. Mean preoperative Merle d'Aubigné score (6.33 ± 0.58), HHS (31.83 ± 5.31) and KSS (28.67 ± 7.97) increased following bilateral lower limb arthroplasty with mean postoperative Merle d'Aubigné score (16.33 ± 0.58), HHS (84.33 ± 5.99) and KSS (86.33 ± 7.09) (P<0.001). Mean NRS decreased from 7.33 ± 0.58 in the preoperative period to 0.67 ± 0.58 at the most recent followup (P [...] Read more.

Mean NRS decreased from 7.33 ± 0.58 in the preoperative period to 0.67 ± 0.58 at the most recent followup (P<0.001). One patient had heterotrophic ossification following THA. There were no revisions. Conclusions: Bilateral lower limb arthroplasty of the hip and knee is a good treatment option to restore function and mobility in MED patients with advanced degenerative arthritis. Careful preoperative planning, meticulous surgical techniques, patient focussed postoperative rehabilitation with multidisciplinary team approach are vital to ensure good functional outcomes and implant survivorship.

The purpose of this study was to examine the Free Sanitary Pad Intervention Programme for Girls’ Education and School Retention in Tolon District in the Northern Region of Ghana. Quantitatively, a descriptive cross-sectional research design was adopted for the study. The study population consist of female menstruating school adolescent girls from these five St, Monica’s R/C, Nyankpala D/A, Nizamia E/A, Islamia E/A and Nawaria E/A junior high schools between the ages of 10 to 22 years who were beneficiaries of CAMFED intervention programmes in the Tolon district. A homogeneous purposive sampling technique was used to select the five junior high schools and the one-hundred and fifty (150) adolescent girls in their menstrual cycle stage. The main instrument for data collection was a semi-structured questionnaire. The data entry and analysis were done by using the SPSS version 20 software package. The data was edited, coded and analysed into frequencies, percentages with interpretations. The study concluded that, there were frequent distribution of free sanitary pads among the beneficiaries’ schools. The study also indicated that the education given to the respondents during the distribution of the free sanitary pads led to improved menstrual hygiene management practices. It is recommended that, schools within the Tolon district should put in place the necessary and adequate toiletry and disposal systems to ensure menstrual hygiene among students especially, girls, during that time of the month. It is also recommended that, Government should make it a priority to provide every school with some sanitary products and drugs to cater for the female student taken by surprise with her monthly flow or the pain associated with mensuration not interfering with her academic work.

Daniel Devote Basil, Lawrence Hart, KuroTamuno Peace Jackson

World Journal of Geomatics and Geosciences 2022, 2(1), 38-46. DOI: 10.31586/wjgg.2022.456

Abstract A hydrographic survey vessel shows three -dimensional movements (Roll, Pitch and Heave) misalignment with respect to the vessel reference unit (VRU) due to environmental effects, such as wind, current, other vessel wakes, etc. These motions if ignored, cause errors in measured depth and in the positioning of the sounding. Hence the need of a motion sensor and gyroscope. However, the alignment of [...] Read more.

A hydrographic survey vessel shows three -dimensional movements (Roll, Pitch and Heave) misalignment with respect to the vessel reference unit (VRU) due to environmental effects, such as wind, current, other vessel wakes, etc. These motions if ignored, cause errors in measured depth and in the positioning of the sounding. Hence the need of a motion sensor and gyroscope. However, the alignment of the multi-beam sonar head to the motion sensor and gyro (Octant) is critical to the accuracy of the determined depths. It is not possible to install the sonar head in perfect alignment with the motion sensor and gyroscope to the accuracy required. The synchronization of the GPS time with the Motion sensor and gyro, the latency of the position, as reported by the GPS as well as the velocity of sound in water are important parameters to account for the misalignment of the motion senor and the multi beam sonar head; this is called the Patch Test. In view of this, a patch test was done to ascertain the mounting angles of EMB 2058 Multi-beam sonar with Octan V installed onboard a survey vessel (Bitam). The result of the Patch test gives a row, pitch and heading value of -1.242˚, -4.92˚, and -0.48˚respectively. The speed of sound in water as measured ranges from; 1531.47m/s to 1531.60m/s within a minimum cast depth of 0.49m and maximum cast depth of 16.00m. The statistical analysis gives and average error of 2.642cm/m2 which was within acceptable standard as define by the International Hydrographic Organization (IHO).

The purpose of the study was to examine technological pedagogical content knowledge of teachers and their formative assessment practices in Social Studies lessons in the Junior High Schools in the Komenda Edina Eguafo Abirem (K.E.E.A) Municipality of Ghana. With a mixed method approach, the study adopted a descriptive survey research design. The population for the study included all Social Studies teachers at the public junior high schools in the in the Komenda Edina Eguafo Abirem Municipality. Purposive sampling technique was used to select all the seventy-four (74) public Junior High Schools and the Social Studies teachers for the study. The purposive sampling technique was used to sample the respondents because they constitute expert knowledge in the subject area and having the same characteristics. The two main instruments used to gather data for the study were questionnaire and observation. Data was analysed using descriptive and inferential statistics. The study indicated that the assessment practices of teachers during Social Studies lessons were on the average. There was disparity between theory and practice as far as the dictates of the profile dimensions are concerned. Teachers mostly assess the cognitive aspect of the child with little attention to the affective domain. The study also concluded that there was a significant positive relationship between TPACK of teachers and their formative assessment practices at 0.05 level of significance. It is recommended that Ministry of Education, National Teaching Council, Ghana Education Service should organize professional development workshop for teachers on their formative classroom assessment practices in Social Studies lessons. It is also recommended that, in order to ensure effective formative assessment practices, Ghana Education Service should collaborate with Colleges of Education and Universities training teachers to develop appropriate TPACK for teachers to improve on their formative assessment practices in the classroom.

Qualitatively the study adopted a case study research design to examine the parental factors that motivate female students to complete formal education in Tolon District. The population for this study comprised of all females in the Tolon District who have successfully completed formal education. A purposive sampling technique was used to select ten (10) females who have successfully completed formal education and are now working in the Tolon District. The main instrument used for data collection was interview. Data were analysed by the use of the Interpretive Method based on the themes arrived at during the data collection. The themes were related to the research question and interpreted on the number of issues raised by respondents. The study revealed that, financial support of parents was vital to enrolment, sustenance and ultimate completion of the education of females. The study also indicated that parents give support in the form of guidance and counseling as well as moral support through encouragement of the Girl-Child played a key role to their successful education. It is recommended that, parents still need more advocacies on the importance of educating the girl child in order to enhance their interest in sending or motivating the girl child in school. It is also recommended that parents should discouraged early marriages to help girls to fully complete their formal education.

Health professionals are the base of the healthcare systems in all societies. Their daily contact with the patient in a context of demanding and difficult working conditions affect their general health. This research was carried out to describe the levels of general health among health professionals and their perceived levels of fatigue and social support. Additionally, the purpose of this study was to examine the above three variables in relation to demographic (education, gender) and employment factors (working hours, department). The research was conducted in 165 health professionals working in hospitals in the region of Eastern Macedonia-Thrace and in the urban centers of Athens and Thessaloniki. The General Health Questionnaire (GHQ-28), the Fatigue Assessment Scale (FAS) as well as the Multidimensional Scale of Perceived Social Support (MSPSS) were used to measure the research variables. The processing and statistical analysis of the data was done using IBM SPSS. The majority of health professionals presented a high score in GHQ-28 subscales indicating low general health (avg 8.59≥5). One hundred thirty nine out of 165 health professionals (84%) were tired and 15 out of 165 (9%) were too tired. The perceived social support was at high levels (avg 5.57). Health professionals exhibit high fatigue and low levels of general health and quality of life. Instead, they receive high social support. Existence of circular hours and work in heavy part worsens the levels of fatigue and quality of life. Measures are needed to increase the number of health professionals and organizational and structural measures to improve their working conditions and strengthen their social work.

This study aimed to examine the pedagogical knowledge base of Religious and Moral Education teachers in assessing students’ academic performance. The research design used for this study was the correlational research design. 159 basic schools were selected to participate in the study. The population of the study comprised Religious and Moral Education (RME) teachers and second-year students in basic schools in the Komenda Edina Eguafo Abirem Municipality in the Central Region of Ghana. Purposive and random sampling techniques were used to select basic schools, Religious and Moral Education (RME) teachers, and students for the study. In all one hundred and seventy-five (175) RME teachers and three hundred and fifty-seven (357) students were selected for the study. The main instruments employed in the study were questionnaires and observation. The data was analysed through the computation of frequencies, percentages, mean of means distributions, and the calculation of correlation coefficient. Pearson’s Correlational Coefficient was used to describe the linear relationship between each of the variables. This was done with the use of computer software called Statistical Product for Service Solutions (SPSS). The study concluded that teachers possessed adequate knowledge about the use of pedagogy or instructional methods when it comes to the teaching of RME. However, as observed, teachers use of the existential approach and the life theme approach only, and, teachers did not make use of the concept cracking approach to teaching RME probably because they lacked adequate information about how to use them. It is recommended that the Ministry of Education, Ghana Education Service, and the National Council for Curriculum and Assessment should organise in-service training for teachers to be abreast with some of these contemporary pedagogies for the teaching of RME in Basic Schools and also make modules available for use at the Colleges of Education to train our upcoming teachers at the Basic Schools.

The main energy conservation opportunities in a dairy plant are in refrigeration, and steam generation. This paper aims to identify potential energy and water savings and opportunities to improve the thermal efficiency of a fluid milk processing plant, using energy analysis and Heat Integration methods. Methodologies for energy analysis and Pinch Analysis with the use of HENSAD and Aspen Energy Analyzer are applied. The main specific energy consumptions are defined as indicators of the progress of improved energy efficiency. The determination of energy performance indicators and energy targets of the heat exchanger network, as well as its design, allowed identifying opportunities for improvement to reduce fuel and water consumption through heat recovery in the milk pasteurization process. Current hot and cold utilities duties are satisfied, for a minimum allowable temperature difference of 20 °C. Total annual savings of 60 t of fuel oil and 15,800 m³ of water allow assessing the feasibility of an investment project for improved heat recovery.

The purpose of the study was to examine the impact of instructional materials in teaching and learning biology in the Colleges of Education in the Central Region of Ghana. Qualitatively, a case study research design was selected for the study. The population of the study consists of three Biology tutors in the three Colleges of Education in the Central Region. The purposive sampling technique was chosen to select all the three colleges and three Biology tutors for the study. The interview guide was the main instrument for the data collection. Data were analysed using the interpretative technique based on the themes arrived at during the data collection from the respondents. The study concluded that instructional materials boast students’ cognitive abilities and arouse their interest in the lesson by helping them to reason critically during teaching and learning. The study also revealed that the competencies level of tutors helps them in the assessment of the subject, selecting relevant materials for each concept. Their pedagogical skills depend on their competencies in the classroom instructions. The study also concluded that a good presentation of a lesson has a substantial impact on teaching and learning situations, as well as the vast amount of information available to students, to supplement their instruction and the principles for appropriate use of instructional materials. It is recommended that professional development should be organised for the Biology tutors in their respective colleges to have competencies in using relevant instructional materials in assessing students in Biology lessons. It is also recommended that Ghana Tertiary Education Commission (G-TEC), National Teaching Council (NTC), and universities should collaborate with the colleges to organise workshops and seminars for tutors teaching Biology to update their knowledge in the use of digital instructional materials in lesson presentation.
