Consumption of fruit which is rich in phenolic compounds and has high antioxidant activity, prevents risk factors of various diseases. Numerous researches confirm that plants rich in such substances reduce the risks of cancer, heart diseases and hypertension. In view of the above, the goal of the research is to study prospective peach varieties in Georgia and compare them in terms of their total polyphenols content and antioxidant activity, determine the correlation between total polyphenols content and antioxidant activity during the storage of fruits. We have studied the total polyphenols content and antioxidant activity in peach fruit of different varieties before and during the storage. The conducted research showed a strong positive correlation between total polyphenols and antioxidant activity. During the storage the total polyphenols and antioxidant activity have decreased in peaches of both varieties. This change can be generalized and considered a common pattern. However, the genotype of a variety affects the strength of correlation.

(1) <b>Background</b>: Psychological flexibility, the ability to adapt to changing demands while staying true to personal values, is linked to better health behaviors. However, its relationship with cardiovascular health behaviors, particularly in Filipino populations, remains underexplored. (2) <b>Aim</b>: This study aimed to examine the relationship between psychological flexibility and cardiovascular health behaviors among outpatients in Rizal, Philippines, focusing on BMI, smoking, physical activity, and dietary habits. (3) <b>Methods</b>: A cross-sectional, descriptive-correlational design was used with 100 outpatient participants from selected hospitals. Psychological flexibility was measured using the Acceptance and Action Questionnaire-II (AAQ-II), and cardiovascular health behaviors were assessed using a modified version of the American Heart Association’s Life Simple 7 tool. Descriptive statistics and Pearson’s correlation were applied. (4) <b>Results</b>: The findings showed that respondents had neutral levels of psychological flexibility. While most exhibited intermediate BMI and physical activity, dietary habits varied. A significant positive correlation was found between psychological flexibility and whole grain consumption. However, no significant associations were found with BMI, smoking, or physical activity. (5) <b>Conclusions</b>: Psychological flexibility appears to influence specific health behaviors, such as dietary choices, but does not strongly correlate with other cardiovascular health behaviors. Further research is needed to explore its broader role in cardiovascular disease prevention.

<b>Background:</b> Peripartum cardiomyopathy (PPCM) is a life-threatening heart muscle disease of unknown aetiology that affects women during the peripartum period, particularly in sub-Saharan Africa. While many studies have observed normal blood pressure (BP) in PPCM patients, none have explored whether their BP is appropriate for their body size. This study investigated the correlation between body anthropometric parameters and BP in PPCM patients, comparing the findings with those of age-matched normal peripartum controls. <b>Methods: </b>A cohort of 105 women, each from PPCM and matched normal peripartum control groups, were recruited from three healthcare facilities in Sokoto. Blood pressure (BP) parameters were assessed in relation to their anthropometric measurements, and the findings were compared between the two groups. <b>Results:</b> The PPCM patients were significantly smaller in body weight (57.0 ±11.6 Kg vs 66.8 ±13.8 Kg, P <.0001), body mass index (BMI) (21.9 ±4.1 Kg/m2 vs 25.4 ±5.4 Kg/m2, P <.0001, body surface area (BSA) (1.3 ±0.7 m2 vs 1.7 ±0.2 m2, P <.0001), Lean body mass (LBM) (45.3 ±7.0 Kg vs 49.4 ±4.1 Kg, P <.0001) and Percentage body fat (BF) (23.5 ±10.9 % vs 31.2 ±6.9 %, P <.0001). Similarly, PPCM patients had significantly higher systolic BP (SBP), Pulse pressure (PP) and Mean arterial blood pressure (MABP) compared to the normal peripartum PPCM control. Further, linear regression analysis showed that there was higher slope of the relationship between anthropometric indices and SBP and PP in the PPCM cohort, compared to the normal peripartum control group. A similar trend of the slope was seen in the Pearson’s coefficient of the relationship of the anthropometries and BP parameters. <b>Conclusions:</b> This study found that women with peripartum cardiomyopathy (PPCM) exhibited disproportionately higher systolic blood pressure (SBP) and pulse pressure (PP) for each unit increase in anthropometric measurements compared to normal peripartum controls. Notably, PPCM patients had significantly lower anthropometric measures, potentially attributable to poverty and chronic undernutrition. Additionally, the effects of poor antenatal care, lack of immunization and recurrent infection should be considered. These findings suggest an abnormal relationship between anthropometry and blood pressure in PPCM patients, which may have detrimental effects on their cardiovascular health. This abnormal relationship may contribute to the development of heart failure (HF) in PPCM patients and potentially increase the risk in women susceptible to PPCM. Even-though our assumption, yet to be proven. To address this concerning trend in vulnerable populations, improvements in nutritional status, socioeconomic determinants health, adequate antenatal care (ANC), immunization, and infection prevention should be considered.

<b>Background: </b>While understanding how corticostriatal connectivity is associated with socioeconomic status (SES), trauma exposure, cognitive function, reward salience, impulsivity, and future substance use is essential to identifying neurobiological pathways that contribute to health disparities and behavioral outcomes, very few studies have tested the role of left caudate resting-state functional connectivity (rsFC) with the cingulo-opercular network as a proxy of corticostriatal connectivity in social, cognitive, and behavioral processes. <b>Objective: </b>This study investigates the associations between left caudate-cingulo-opercular connectivity and multiple biopsychosocial domains, including low SES, high trauma exposure (financial and life events), cognitive function, reward salience, impulsivity, depression, and future substance use (tobacco and marijuana use). <b>Methods: </b>Resting-state functional magnetic resonance imaging (rs-fMRI) data were analyzed to assess connectivity between the left caudate and the cingulo-opercular network. Data on socioeconomic status, trauma exposure, cognitive performance, and mental health were collected from participants. Future substance use behaviors were evaluated through longitudinal follow-ups. Correlation and regression analyses were conducted to examine relationships between corticostriatal connectivity and the targeted domains. <b>Results: </b>Corticostriatal hypoconnectivity was associated with lower SES, higher trauma exposure, poorer cognitive function, heightened reward salience, higher impulsivity, and history of depression. Additionally, corticostriatal hypoconnectivity at baseline predicted future tobacco and marijuana use during follow-up years. <b>Conclusion: </b>Corticostriatal hypoconnectivity, particularly the rsFC between the left caudate and the cingulo-opercular network, may represent a potential mechanism linking a wide range of social, emotional, and behavioral problems in youth. These findings suggest that corticostriatal hypoconnectivity could serve as a neurobiological marker for identifying individuals at risk for depression, low cognitive function, high reward salience, impulsivity, and substance use, emphasizing the interplay between socioeconomic and neurocognitive factors in shaping behavioral health trajectories.

The objective of this research was to investigate work-family conflict among management staff of hotels in the Accra Metropolis of Ghana. The study employs the pragmatism approach and 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. Stratified, random and convenient sampling techniques were used to select 182 out of 356 respondents. One hundred (100) were sampled using a formula and a table determination of sample size based on the confidence level needed from a given population as provided by Krejcie and Morgan in 1970 for the study. Ten managers were conveniently interviewed on the issues of work-family conflict. The main instruments for data collection were a questionnaire and a semi-structured interview guide. This study adopted factor analysis and a structural equation model to examine factors that influence work-family conflict. This statistical technique was used in the research to investigate the factorability of the variables of work-related and family-related factors separately and a structural equation model was used to combine both factors to better understand the relationship. Linear regression was used to determine the relationship between work-family conflict. Pearson product-moment Correlation and structural equation model were used to determine the consequences of work-family conflict. It can be concluded that both work-related such as work overload, job type and involvement as well as family-related factors such as life cycle stage, and childcare arrangement predict work-family conflict among managers of hotels in the Accra metropolis. It is also deducted WFC affect managers’ performance on the job, exhaust them emotionally and also influences their intentions to leave the job for another. Managers usually feel fatigued to prepare for work and physically drained after work. They also feel depressed and emotionally drained sometimes. It is recommended that top management of hotels should allocate a budget to build an organisational culture that encourages work-family balance. Frontline managers should be trained to be aware of the benefit of providing support in the work environment that will help staff balance work and family. It is also recommended that hotel jobs be redesigned by the human resource unit to reduce workload and make it more interesting for managers so they may not feel overworked. Overworking of managers will enhance their intentions to quit the job and this will be costly for hotels.

A regular menstrual cycle is important to maintain a woman’s fertility. This cycle has been linked to optimal function of the thyroid gland in the production of its hormones. Disturbance of thyroid gland functions could result to female infertility due to changes in menstrual patterns.<b> </b>Aim of this research was to determine the correlation between thyroid gland functions and menstrual patterns amongst infertile and fertile women attending a tertiary care hospital in North-Central Nigeria.<b> </b>This comparative, cross-sectional study recruited 106 women who visited the hospital's Gynecology Clinic and Family Planning Clinic. 53 of the 106 patients were women with a history suggestive of either primary or secondary infertility and the remaining 53 women with no history of infertility served as the control. A well-structured questionnaire was used to obtain data on the patients’ menstrual patterns. Anthropometric data were measured and obtained. Collected blood samples were analyzed using Enzyme-Linked Immunosorbent Assay (ELISA) technique to determine the serum levels of thyroid hormones. All obtained data was analyzed, and the level of significance was set at <i>p</i><0.05, at a 95% confidence interval.<b> </b>33 patients had menstrual anomalies (78.8% infertile women; 21.2% fertile women who served as control, <i>p</i>=0.012). The incidence of menstrual anomalies in the infertile women group and control group was 7.5% versus 0.0% for amenorrhea; 20.8% versus 5.7% for menorrhagia; 9.4% versus 7.5% for oligomenorrhea; 7.5% versus 0.0% for hypomenorrhea; nil polymenorrhea for both groups; and 50.9% versus 86.8% for normal menstrual patterns. Ten (9.43%) patients were diagnosed with thyroid dysfunctions (80% in infertile group; 20% in control group, <i>p</i>=0.046). Six (18.2%) out of 33 women with menstrual anomalies were diagnosed with thyroid dysfunction. Five (83.3%) out of these 6 women with both menstrual anomalies and diagnosed thyroid dysfunction were infertile while only one (16.7%) was fertile.<b> </b>Thyroid gland dysfunction correlates strongly with abnormal menstrual patterns, which implies that it is vital to evaluate thyroid hormone levels in blood serum in the course of treating menstrual irregularities and female infertility. Early detection of thyroid dysfunction is important in achieving a positive treatment outcome for female infertility.

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.

Avian influenza (bird flu) occurs sporadically in American poultry flocks, decimating these flocks and causing substantial economic losses. Avian influenza also impacts the beliefs of food handlers and preparers in the home (home cooks). Although those who properly handle and prepare processed poultry products cannot succumb to avian influenza, there is a widespread belief that one can contract the bird flu from these foods. Beliefs about getting avian influenza from poultry products and intentions to avoid consuming poultry products are the focus of this study of 285 home cooks. False beliefs about getting avian influenza from handling, preparing, and consuming poultry products are apparent in this sample. Correlational analysis also shows that those holding the false beliefs intend to act upon those beliefs by planning not to consume poultry products. Moreover, the false beliefs about contracting avian influenza from poultry products are correlated with a bias to see oneself as less likely to produce food that contains foodborne diseases. These findings are consistent with, and contribute to, the research literatures on belief formation and change, behavioral intentions, and with research showing how guilt by association thought processes underlie false beliefs related to food safety. This research has important implications for poultry and other food processing industries, and for campaigns to persuade the public about real and imaginary risks associated with particular food products.

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 purpose of this study was to evaluate teachers’ technological pedagogical content knowledge and pupils’ academic performance in Religious and Moral Education (RME) in basic schools in the Ga-South Municipality of Ghana. Correlational research design was used for the study. The population of the study comprised RME teachers and final year pupils in the basic schools in the Ga-South Municipality. Krejcie and Morgan table, cluster sampling technique multi-stage sampling technique, proportional allocation of sample size, and purposive sampling were used to select, 532 respondents (159 basic schools 357 pupils and 175 RME teachers) for the study. The main instruments for data collection were questionnaire, observation guide, standardised-achievement-test. The Pearson’s Correlational Coefficient was used to describe the linear relationship between each of the variables in the data analysis. The study concluded that it was uncertain as to whether teachers possessed adequate knowledge about the use of technology or instructional resources when it comes to the teaching of RME. The study also indicated teachers did not make effective use of the technology or instructional resources as observed, probably because they do not recognize the important role the use of technology plays in the teaching and learning process, they did not know how to use some of these technologies. Besides, some of these technologies were not available for use in the schools. Although, there was a weak positive correlation between teachers’ technological knowledge and pupils’ academic performance, the important role that technology plays in the teaching and learning process cannot be ruled out. It is therefore recommended that, the Ministry of Education, Ghana Education Service and Curriculum Research and Development Division should organise in-service training for teachers, since it turned out during the observation sections that teachers did not make use of audio-visuals (TV and motion pictures) and audio materials (example radio and tape recorders) in the Ga South Municipality.

The savant syndrome is a syndrome that is associated with certain cognitive disorders and is as-sociated with limitations but also with individual significant abilities. The nature and expression of the syndrome is very heterogeneous, which means that many facets of the syndrome have not yet been researched. The object of the study described below was to approach the research gap on the topic of "work and employment" in particular with initial results, since up to now both topics have only been adequately researched in isolation. In doing so, the influence of the profit orienta-tion of organisations on the employability of savants was investigated. Correlations between non-profit organisations and companies with other parameters such as the implementation of a company health management or the general employment of severely disabled people could al-ready be proven in previously conducted studies. The method used was a quantitative survey of 465 dependent employees. The ability to integrate was expressed by a total score, which was an additive index consisting of the dimensions strengths, weaknesses and framework conditions. Although the proportion of severely disabled employees is higher in the public sector and compa-ny health management is also partly obligatory, no significant differences in the employability of island gifted people could be found compared to the free economy.

Motor development is known for its constant evolution, as it allows a baby to develop his motor skills and perform complex and coordinated movements. Such knowledge on the subject is extremely important for the physical therapist, so that he is able to deal with certain situations, which include pathological conditions and developmental delays, requiring intervention and rehabilitation, thus making implications for cerebral palsy (CP).

The purpose of the study was to assess Academic achievement of Low- Social-Economic-Status (SES) of Junior High School Students in Ghana. The study employed a descriptive, cross-sectional survey design. The population for the study comprised all JHS students and teachers in the Aboom Circuit of the Cape Coast Metropolis. Krejcie and Morgan (1970) sampling table, Purposive and randomly sampling techniques were used to select schools, teachers and students for the study. The sample frame for the study was all students and teachers in the five selected JHS of the Aboom Circuit of the Cape Coast Metropolis. The sample size for the study was 350 for students and 30 for teachers. The main instrument for data collection for the study as questionnaire. Research question was analysed using mean and standard deviation; hypothesis was analysed using Pearson Product Moment Correlation. The study revealed that continued, consistent and persistent presence of these student-related factors such as hunger, lack of self-motivation, poor study habit, watching TV, laziness, and students’ truancy or absenteeism negatively affect students’ academic achievement. The results of the study also indicated that there was a moderate, negative correlation between student-related factors and students’ academic achievement with high levels of perceived student-related factors with low levels of students’ academic achievement. It is recommended that, the role of guidance and counseling session in schools is to assists students to be focused on their studies. Therefore, guidance and counseling sessions in various schools should be effectively organised to prevent students’ truancy. It is also recommended that School administrators in partnership with PTA leadership and NGOs should educate students on the relevance of education and give social support to students from low socio-economic backgrounds and motivate them in their studies.

The objective of the study was to examine the school-related factors that contribute to the academic achievements of low- social economic – status of students in the Aboom Circuit of the Cape Coast Metropolis during 2015-2016 academic years. The study adopted descriptive survey research design. Purposive and random sampling techniques were used to select teachers, schools and students. The five junior high schools (St Nicholas, St. Monica, Aboom Methodist B, Aboom Zion A and Aboom Zion C) were randomly selected from the ten schools in the circuit. A proportional allocation was used to determine and allocate the total number of students from the population to each school. The main instrument for data collection was questionnaire. The data were entered in a pre-designed template in the Statistical Package for Social Science (SPSS) software, version 21. The data were analysed using descriptive (frequency and percentages, mean and standard deviation) and inferential statistics (correlation). The research hypothesis was also analysed using Pearson Product Moment Correlation. The hypothesis was tested at 0.05 level of significance. The study indicated that school-related factors such as school time schedule, resources, school climate, guidance and counselling, school-parents’ relationship may significantly contribute to students’ academic achievement. It is also concluded that when the right atmosphere or conditions are created, students can perform well irrespective of their socio-economic statuses or backgrounds. It is recommended that the Ministry of Education (MOE)/Ghana Education Service (GES) in partnership with school administrators should provide adequate teaching and learning resources and facilities for effective teaching and learning at the school. It is also recommended that in other to ensure effective teaching and learning, the Ministry of Education (MOE) and the Ghana Education Service (GES) should collaborate to implement a class size reduction policy effectively as expected. This means that the student-to-teacher ratio should strictly be adhered to.

The duck industry makes an important contribution to the availability of animal protein sources in Egypt, little known about the genetic parameters, particularly the heritability and genetic correlations of body weight and egg production in ducks. Body weight is the most essential feature for genetic improvement due to its ease of selection, high heredity, and large impact on meat production costs. The target of this study was to evaluate and explain genetic parameters such as the heritability, the genetic and phenotypic correlations, and sire breeding value in Domyati (local) and Khaki-Campbell (foreign) ducks in order to improve body weight and egg traits. A total of 160 (80 Domyati and 80 Khaki-Campbell ducks utilized to measure body weight at 16 and 20 weeks g), as well as 7000 eggs (2500 Domyati and 4500 Khaki-Campbell) to measure egg traits (the egg number, egg weight, and egg mass are all measured throughout the first 90 days of laying). In Domyati and Khaki-Campbell ducks, the heritability estimated for body weight was moderate to high, ranged from 0.35 to 0.40, and 0.21 to 0.30 for egg production. The genetic correlations among body weight and egg traits were all positive and had high values, also among BW16 and BW20 were stronger (0.90); (0.99). So the genetic improvement in BW16 could be followed by an increase in BW20 weeks. It concluded that, the relatively high value of genetic heritability for body weights and egg traits in Domyati and Khaki-Campbell ducks, indicates that it is possible to genetically increase body weight and egg traits through selection and subsequently inbreeding to divide the herd into groups that are selected among themselves to keep their sons.

The aim of the research was to examine the influence of parenting styles on academic performance of students in Aowin Municipality in the Western North Region of Ghana. Descriptive survey design was employed to collect quantitative data from the respondents. The study targeted all final year public junior high school students in the Aowin Municipality. A multi-stage sampling technique which involved the use of probability sampling techniques was employed to select 252 respondents with 142 boys and 110 girls. The main data collection instrument was questionnaire with 46 items. Document analysis was also performed on the pupils’ end of term examination results. Means, standard deviation, multiple regression, Pearson’s Product Moment Correlation and Chi-square were employed to analyse the data. The results revealed that authoritative parenting style dominates in parents of the JHS students in the municipality. The study concluded that, Authoritative parenting style predominates in JHS students in the Aowin municipality. There was a correlation between the parenting style of parents and the academic performance of JHS students. It was seen that, student coming from the authoritative parenting style had high performance than those coming from the authoritarian, permissive and neglectful parenting style. Students from neglectful parenting homes demonstrated low performance in school. It is recommended that policies should be developed by Ministry of Education to encourage parents to adopt appropriate parenting styles like the authoritative parenting style which has been revealed by this study as related to good academic performance. Management of various schools should collaborate with Parent-Teacher Association to organize seminars and workshops to educate parents on the influences of the various parenting styles on their children academic performance. This will enlighten parents on employing effective parenting style like authoritative parenting style that has been revealed by this study to correlates with high academic performance.

The impact of narcissism and self-esteem on academic achievement has long been an important issue in developmental research. The study aimed to explore the students’ narcissism and self-esteem as correlates of academic achievement in Mathematics in Anambra State. Five research questions and five null hypotheses guided the study. The study adopted a correlational approach. The population of the study comprised of 21204 SS2 students from which a sample of 630 was drawn. Multi-stage procedure was used to select the sample. Two standardized research instruments namely; Narcissistic Personality Inventory (NPI), and Self-esteem Questionnaire (SQ), as well as score from students’ promotional examination were used for data collection. Cronbach’s alpha was used to determine the reliability of the items in the instruments. The overall reliability coefficient was 0.75 which shows that the instrument was reliable and good for the study. The Pearson Product Moment Correlation was used to answer research questions 1 to 4 and to test hypotheses 1 to 4, while the research question 5 and hypothesis 5 were answered and tested with multiple correlations. The findings showed that students’ power narcissism recorded a very low positive relationship with academic achievement in mathematics. Findings also revealed that the multiple correlation of these variables is positively non significant with academic achievement in mathematics. Based on these findings, it was recommended that as narcissistic individuals believe strongly that they are better than others, teachers and counsellors should develop a strategy to enhance the confidence and ability in the students as these will help them to become life long learning individuals thereafter.

Polychlorinated biphenyls (PCBs) are important class of persist organic pollutants that were used as a component of paints especially in printings, as plastificator of plastics and insulating materials in transformers and capacitors, heat transfer fluids, additives in hydraulic fluids in vacuum and turbine pumps. There is always a need to establish reliable procedures for predicting the bioconcentration potential of chemicals from the knowledge of their molecular structure, or from readily measurable properties of the substance. Hence, correlation and prediction of biococentration factors (BCFs) based on λ<SUB>max</SUB> and vibration frequencies of various bonds viz υ(C-H) and υ(C=C) of biphenyl and its fifty-seven derivatives have been made. For the study, the molecular modeling and geometry optimization of the PCBs have been performed on workspace program of CAChe Pro 5.04 software of Fujitsu using DFT method. UV-visible spectra for each compound were created by electron transition between molecular orbitals as electromagnetic radiation in the visible and ultraviolet (UV-visible) region is absorbed by the molecule. The energies of excited electronic states were computed quantum mechanically. IR spectra of transitions for each compound were created by coordinated motions of the atoms as electromagnetic radiation in the infrared region is absorbed by the molecule. The force necessary to distort the molecule was computed quantum mechanically from its equilibrium geometry and thus frequency of vibrational transitions was predicted. Project Leader Program associated with CAChe has been used for multiple linear regression (MLR) analysis using above spectroscopic data as independent variables and BCFs of PCBs as dependent variables. The reliability of correlation and predicting ability of the MLR equations (models) are judged by R<SUP>2</SUP>, R<SUP>2</SUP><SUB>adj</SUB>, se, q<SUP>2</SUP><SUB>L10O</SUB> and F values. This study reflected clearly that UV and IR spectroscopic data can be used to predict BCFs of a large number of related compounds within limited time without any difficulty.
