Abstract

In the region of Shkodra, private wells serve as a source of water for some families, both in urban and rural areas, for many activities. The main purpose of this study was to comprehensively assess the microbial quality of well water, with the aim of understanding its potential impact on public health among populations who use this water for daily consumption. The study included 10 monitoring stations during the period September 2023 to August 2024 with a total of 80 water samples were analysed, for Intestinal enterococci and Escherichia coli. The application method for microbiological use of well water is that of the ISO membrane filter ISO7899-2:2000, SM 922 B-2015. Intestinal enterococci dominated in 65% of the samples. As for the water source diseases encountered by residents, E. coli infections dominate with 90.36%, S. typhimurium 8.36%. From the correlation analysis result Escherichia coli disease correlates 80% with the presence of Intestinal enterococci in well water and 80% presence of Escherichia coli disease. The results of this study demonstrate that the high presence of pathogens in well water poses a risk to public health. Well contamination is mainly caused by untreated wastewater, nearby septic tank, animal waste. The novelty of this study lies in the fact that, for the first time, a correlation was applied between the microbial contamination of well water and the diseases resulting from its use, thereby confirming the relationship between water quality and public health.

Abstract

Studies of immersive technologies as transformative tools for the teaching of science are on the rise but very few empirical studies have been done to compare immersive to semi-immersive and traditional methods. The purpose of the current study was to analyse the effects of three different levels of immersion-virtual reality (VR), interactive whiteboards (IWB) and traditional teaching-on tenth-grade students’ biology achievement in the topic of cell division. A quasi-experimental design of teaching that had three groups (VR group, n = 72; IWB group, n = 58; control group, n = 64) was used. The same qualified biology teacher taught all three groups, using semi-immersive, fully immersive, and traditional teaching through nine teaching sessions. An achievement test (validated for content reliability) was given as a pretest and a post-test. The pretest established the groups equivalently; and the post-test measured student learning gains since the three teaching methods could count for their test scores. ANCOVA results revealed that there were statistically significant differences in the groups’ achievements. The VR group scores were the highest and the IWB group, the second highest-while the control group received the lowest post-test scores. The results suggest that more immersive teaching effects positively aided learning comprehension of abstract biological processes like cell division. The significance of the study was its direct comparison of fully immersive, semi-immersive and traditional teaching of the topic, providing practical implications for integrating VR into science classrooms to enhance students’ comprehension of abstract biological processes.

Abstract

This study investigates the relationship between ESG-associated financing and capital structure optimization, as well as their subsequent impact on corporate financial performance (CFP) within the financial services sector. It highlights the moderating role of market uncertainty and aims to fill existing gaps in the literature by empirically evaluating the effectiveness of sustainability-driven financial strategies in dynamic market environments. Employing a quantitative research design, this study surveyed 385 professionals from banks, insurance companies, and fintech firms located in Southeast Asia, utilizing stratified random sampling methods for data collection. The analysis employed descriptive statistics, Cronbach’s Alpha for reliability assessment, Exploratory Factor Analysis (EFA) for construct validation, and multiple linear regression analysis via SPSS to test the research hypotheses. The findings indicate that ESG-associated investment has the most significant influence on CFP (β = 0.534), closely followed by capital structure optimization (β = 0.427). Additionally, market uncertainty serves as a moderator for both relationships (β = 0.367 and β = 0.421, respectively), with its effects becoming more pronounced during volatile conditions. These results highlight that ESG strategies and optimized capital structures are not only performance-enhancing but also crucial resilience mechanisms under uncertainty. The study contributes to signaling, trade-off, and institutional theories by contextualizing ESG-financial decisions in emerging markets. Practically, financial institutions and policymakers should integrate ESG-linked financing instruments and flexible capital planning to improve performance and stability under volatile market conditions.

Abstract

This study explores the intricate relationship between vocational education and training (VET) and national productivity in Bulgaria through a multidimensional analysis that integrates macroeconomic data with institutional-level perspectives. Employing a mixed-method design, it combines national time-series data from 2003–2023 with survey responses from 63 VET educators in information technology and engineering. Quantitative analysis using total factor productivity (TFP) and labor productivity decomposition, supported by Granger causality tests, reveals a unidirectional link in which productivity growth drives VET participation, but not vice versa indicating that Bulgaria’s VET system struggles to convert economic expansion into human capital enhancement. Qualitative findings highlight systemic barriers, including outdated curricula, inadequate digital infrastructure, weak labor market alignment, and limited industry collaboration. Despite educators’ high self-rated competence, the institutional mechanisms for feedback and adaptation remain underdeveloped, resulting in a structural disconnect between educational provision and economic demand. The novelty of this study lies in its integrated macro–micro analytical approach, which bridges national productivity trends with educator-level realities—an underexplored nexus in the context of Central and Eastern Europe. By merging economic modeling with pedagogical insights, this research advances a more comprehensive understanding of how VET systems contribute (or fail to contribute) to national productivity. The study concludes with targeted policy recommendations, including the implementation of European quality assurance frameworks (EQAVET, ECVET), modernization of training programs, and investment in sustainable partnerships between VET institutions and industries to foster inclusive, innovation-driven economic growth.

Abstract

Low motivation among students in learning mathematics, which is often viewed as abstract and disconnected from everyday life, remains a persistent challenge in Indonesian education. This study aims to develop and test the effectiveness of a 3D animated film based on ethnomathematics integrated with the Project-Based Learning (PjBL) model to enhance students’ learning motivation and cultural appreciation. The research employed a Research and Development (R&D) approach following Borg and Gall’s model through several stages: product design, expert validation, preliminary trials, field implementation, and operational evaluation. The participants consisted of junior high school students divided into control and experimental groups. Data were collected through expert validation sheets, student response questionnaires, and learning motivation scales. The validation results indicated that the 3D animated film achieved a score of 82%, categorized as “good” and suitable for classroom implementation. Statistical analysis revealed a significant increase in learning motivation in the experimental group compared to the control group, as evidenced by higher pretest–posttest gain scores. The novelty of this study lies in the integration of 3D animation and ethnomathematics within the PjBL framework an innovative combination that contextualizes mathematical concepts through local cultural wisdom while promoting active, project-based engagement. This research contributes to the growing field of culturally responsive digital learning media by demonstrating that ethnomathematics-based animation not only enhances motivation but also bridges traditional cultural values with modern technological learning approaches, offering a scalable model for 21st-century mathematics education.
