Calabria is a floristic hotspot just at the center of Mediterranean Sea. Unfortunately, an increasing number of alien plant species threats this natural heritage, exactly while the crucial role of botany in secondary schools of Italy has been definitely dismantled. Calabrian Native Project is an environmental education project planned by Istituto Tecnico Agrario of Catanzaro that, reintroducing some key concepts of botany and biogeography, allowing pupils to experience a botanical excursion in the close-to-the-school Mediterranean Biodiversity Park, gives them the opportunity to become acquainted with both native and alien species. Pupils are asked to collect native plant propagules and to seed or cultivate the material in the school greenhouses, and to take care of these plants until their use. The prevalent outdoor and laboratory approach to the issue of bioinvasions, make the project very effective. This feature, with the low cost and reduced technology inputs, make the project highly replicable in other contexts, just focusing appropriate target species.

The Free Senior High School (FSHS) policy implementation in Ghana has garnered significant attention in academic research, with various studies delving into its advantages and implementation obstacles. Nevertheless, there has been a rise in school dropout rates among secondary school students amidst the programme implementation. There is therefore the need for a more localized scientific inquiry into the socio-economic factors contributing to school dropout among Senior High School (SHS) students in the Abofour community. The study employed a qualitative approach, using the case study design to conduct interviews with 22 students who had dropped out of SHS, to explore their experiences and identify key socio-economic factors influencing their decisions to leave school. Thematic data analysis revealed six main themes, namely, lack of parental support, peer influence, early marriage and pregnancy, economic conditions, and unsupportive school environment, as among the causative factors. The findings suggest that while the Free SHS policy has removed some direct financial barriers, other social, economic, and institutional factors continue to spur up dropout rates. The study concludes that addressing these underlying issues requires a multi-faceted approach that includes strengthening family support systems, improving school environments, and providing targeted interventions for at-risk students. In this regard, policymakers and other educational stakeholders are required to provide targeted supports to enhance student retention and reduce dropout rates in the Abofour community.

Biodiversity Conservation is a priority issue for the scientific community, and a main subject in the Biology and Geology curriculum at secondary school level in Spanish Educational System. In the present didactic proposal, we use the demographic monitoring of an endangered plant species to illustrate a research tool for estimates of biodiversity loos in nature, the local endemic Astragalus tremolsianus Pau. The aim of the proposal is to bring students closer to a real experience, which brings together knowledge of Biology, Algebra and Trigonometry, through Information and Communication Technologies (ICTs). Showing a census to monitor the populations of a threatened high mountain flora species into the classroom is an innovative teaching activity that combines and uses knowledge from different disciplines, as well as demonstrating a real application of the knowledge acquired. The use of mathematical tools encompasses a number of skills that require the application of mathematical principles and processes in the scientific context. The introduction of the structure of scientific texts is another positive aspect of this didactic experience.

Caesarean section is the most common surgical procedure in obstetrics, but also in pregnant women with dystocia. The purpose of this study is to identify factors that contribute to post-caesarean complications in emergency of gynecology-obstetrics service of Saint Joseph Hospital in Kinshasa. This is a descriptive cross-sectional study and was conducted at Saint Joseph Hospital in Kinshasa city for a month (1^st and 30^th July 2021). A questionnaire was used to collect different data namely socio-demographic characteristics and different variables important for the study. Independent variables were factors related to the parturient and the current pregnancy, the surgical procedure and the operational room. While the dependent variable was post-caesarean complications in gynecology-obstetrics service. Descriptive statistical analyses namely frequency and percentage were done to describe the sample profile. To measure the strength of association between different variables were estimated using Pearson's Chi-Square (X²) test and the p-value was 0.05. Data analysis was performed using SPSS version 20 software. The majority of participants are over 33 years of age, have secondary school skills, married and have 3 to 4 children. It was observed that 88.2% of participants have acute respiratory distress prior to caesarean section, 76.6% have a personal history of thromboembolic disease prior to caesarean section. All the participants who underwent caesarean section were victims of external ventilation through the windows of the operating room, which remained open before, during and after the surgery and benefited from antibiotic treatment without any para-clinical analysis before the caesarean section. Furthermore, 82.4% of participants had benefited from the caesarean section with sterilized care materials 48 hours before and after the intervention. While 47.1% of participants had caesarean sections with defective equipment for the operation (use of dry heat sterilization etc.). A better identification of these risk factors can reduce significantly rate of complications and can consequently improve the maternal-infantile prognosis. The obstacles to effective management are related to the provision of quality services.
