The attitude towards bilingualism in education has completely changed in the contemporary period. The current study shows that bilingualism has a clear advantage, as cumulative research data conducted over the past three decades in various locations around the world shows that people who can develop their linguistic potential receive cognitive, social, personal and economic benefits. In addition to linguistic, academic and cognitive outcomes, bilingual education promotes the absence of prejudice and acceptance of cultural diversity. At the same time, the issue of the development of professional, communicative and intercultural competencies and autonomy in the context of learning in several languages remains a rather acute topic. However, contrary to the concerns expressed due to higher cognitive requirements in bilingual programs, these problems are solved by effective teaching methods and curricula. The quality of teaching is another objective that the educational reform program is aimed at, and quality teaching will be crucial for the success of bilingual education. In addition, the development of appropriate complex and contextualized curricula for both languages is also crucial. It is these two aspects that will be discussed in detail in this article.

Authors: Disu Kehinde
Published: January 2025

Background: In Nigeria, family planning is essential to address high rates of unintended pregnancies and associated health risks. Despite widespread awareness of contraceptive methods, uptake among women of reproductive age remains low due to socio-cultural, economic, and individual factors. Addressing these barriers is crucial for improving reproductive health outcomes and empowering women.

Objective: This study examined the barriers and facilitators of contraceptive uptake among women in selected markets in Oyo State, Nigeria, focusing on socio-demographic factors, knowledge, attitudes, and partner support.

Method of Analysis: A mixed-methods approach was employed, combining quantitative and qualitative data. Descriptive statistics and chi-square tests (p < 0.05) analyzed socio-demographic characteristics and their associations with contraceptive use, while thematic analysis explored qualitative insights.

Results: Awareness of contraceptive methods was high (85%), with condoms being the most recognized method (88.3%). However, only 57.5% reported usage, with 83.3% citing concerns about health risks and side effects as barriers. Partner support significantly influenced contraceptive intentions (χ² = 15.67, p < 0.001), as 87.5% of women intending to use contraceptives had partner support. Education level and marital status were also significantly associated with contraceptive use (p < 0.05).

Conclusion: High awareness contrasts with low usage due to misconceptions and insufficient partner support. Addressing these barriers through targeted education and promoting partner involvement can improve contraceptive uptake and reproductive health outcomes for women in Oyo State.

Published: January 2025

In this study, we combined discrete mathematics with computational biology to identify Brucella species using clustering algorithms. By analyzing the Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF MS) spectra of 44 Brucella isolates, which included 21 Brucella melitensis, 12 Brucella suis, and 11 Brucella abortus, we utilized a feature selection strategy to pinpoint 22 key characteristics critical for species differentiation. We then developed a spectral clustering-based model for Brucella traceability. This model offers a rapid and cost-effective alternative to traditional, labor-intensive identification methods, significantly improving the efficiency and accuracy of Brucella strain identification. Additionally, it aids in monitoring disease transmission trends, identifying outbreak sources, and formulating effective control strategies to mitigate risks. Our findings demonstrate the practical application of discrete mathematics in computational biology, contributing significantly to both scientific research and educational methodologies. This approach illustrates how mathematical concepts can be effectively applied to solve real-world biological problems, providing valuable insights for future interdisciplinary studies and innovative solutions.

Published: January 2025

The Soil Health Card (SHC) program aims to enhance soil health by providing farmers with detailed information about the nutrient status of their soil. This study investigated farmers’ perceptions, challenges, and potential pathways to enhance the adoption of SHC recommendations in Haryana. The analysis was based on primary data collected through face-to-face interviews with SHC adopters and non-adopters, utilizing a pre-tested semi structured schedule in 2024. The findings revealed that farmers’ perceptions of the benefits of the SHC remained low. The perceived constraints in obtaining SHC scored higher than those associated with implementing its recommendations. The study identified the annual lease land system as a key factor driving the indiscriminate use of fertilizers in the state. Although the recent reduction in the per-bag quantity of urea decreased usage in Haryana, any further reduction in bag weight might result in increased fertilizer consumption. The study recommended the use of mobile soil testing vans and timely delivery of soil health cards to promote greater adoption.

Authors: Bharne Saurabh , Yadav Pushpender , Jatav Surendra Singh
Published: January 2025

Indian farmers jointly follow farm risk management and livelihood diversification to augment their income for better well-being. The uncertainties in climatic conditions and rural employment market pose dangers of income insecurity to already low-incomed farmers. Crop insurance is a promising production risk management technique, which, through Pradhan Mantri Fasal Bima Yojana (PMFBY), seems beneficial in improving Indian farmers’ well-being by ensuring financial support during crop loss. Similarly, Mahatma Gandhi National Rural Employment Guarantee Scheme (MNREGS) provide income security by ensuring guaranteed regular employment. This paper strives to contribute to the knowledge related to PMFBY and MNREGS. The Binary Logit Regression results suggest that marginal and small farmers are less involved in both whereas socially marginalized farmers participate more in MNREGS but less in PMFBY. The possession of education, agricultural training and crop loss experience enhance their participation in both. Further, the Propensity Score Matching (PSM) results of all the three different matching methods suggest the positive impact of PMFBY and MNREGS on household usual consumption expenditure. The study suggests to enhance crop insurance adoption by boosting education, agricultural training, and membership in farmer organization. Further, ensuring diverse livelihood opportunities to farmers for their improved well-being.

Aim: The purpose of this study was to compare the effects of different finishing and polishing procedures for monolithic CAD/CAM ceramics on their optical properties after ultraviolet (UV) aging.
Material and Methods: A zirconia-reinforced lithium silicate ceramic (Vita Suprinity) with a thickness of 1.5 mm was selected for this study. A total of 42 samples were prepared and divided randomly into six groups on the basis of the finishing–polishing technique used: disc, polishing paste and glazing or combinations (n=7). Color change measurements of the samples were performed on a gray background before and after UV aging. The translucency values on white and black backgrounds were calculated after UV aging according to the CIEDE2000 formula. The Kruskal‒Wallis H test and post hoc Dunn test were used for the statistical analysis (P<0.05).
Results: The effects of finishing–polishing procedures were statistically significant in terms of color change and translucency (P<0.001). The highest color change was found in the crystallized samples. The samples polished with polishing paste after crystallization and glazing exhibited the lowest color change. The lowest translucency was presented in the samples that just crystallized. The highest translucency was presented in ceramics crystallized with glaze, which was significantly different from that in those crystallized, crystallized+polished with discs, and crystallized+polished with polishing paste ceramics (P<0.001).
Conclusion: Finishing ceramic restorations is an important step for long-term clinical use. Glazing or mechanical polishing of zirconia-reinforced lithium silicate ceramics produces similar results in terms of optical properties. Crystallization with glazing together can be used for quick and reliable finishing.

Published: January 2025

Introduction: Acetylcholine (ACh) is a fundamental neurotransmitter in the parasympathetic nervous system, mediating smooth muscle contraction through muscarinic receptors. Understanding its interaction with antagonists such as atropine provides insights into pharmacological modulation of smooth muscle activity.

Objective: The study aimed to evaluate the competitive interaction between ACh and atropine on muscarinic receptors in guinea pig ileum and to characterize the receptor-binding dynamics, particularly focusing on atropine’s inhibitory effects.

Methodology: The research utilized isolated guinea pig ileum tissues, which were exposed to increasing concentrations of ACh in the absence and presence of atropine. Concentration-response curves were generated to determine receptor affinity and inhibitory effects. Equilibrium dissociation constants for both ACh and atropine were calculated to analyze the binding properties and competitive nature of the interaction.

Results: Atropine was confirmed as a competitive antagonist of muscarinic receptors, effectively reducing the contractile responses induced by ACh. The data demonstrated that atropine prevents ACh binding, thereby inhibiting smooth muscle contraction, as evidenced by significant shifts in concentration-response curves. These findings reaffirm atropine’s role as a potent therapeutic agent for conditions involving cholinergic overactivity.

This study investigates the relationship between the availability of laboratory resources and student engagement levels among Grade 12 STEM students at Dologon National High School. A quantitative approach was employed, utilizing a structured survey administered to 66 students to assess their access to laboratory resources, frequency of participation in laboratory activities, and levels of engagement. The results indicated that students perceived adequate access to laboratory resources, with an overall mean score of 3.88 categorized as “agree.” Additionally, student engagement was evaluated through behavioral (mean = 4.35), emotional (mean = 3.79), and cognitive engagement (mean = 4.07), yielding an overall engagement mean of 4.07, also classified as “agree.” A moderately strong correlation (r = 0.49) was found between the availability of laboratory resources and student engagement, suggesting that increased access to resources positively influences student involvement in science activities. These findings align with existing literature emphasizing the importance of well-equipped laboratories in fostering student participation and interest in STEM education. The study highlights that while students demonstrate strong behavioral engagement, there is potential for improvement in emotional engagement to enhance overall learning experiences. Ultimately, the research advocates for educational institutions to prioritize equitable access to laboratory resources and implement strategies that foster an engaging learning environment, thereby preparing students for future challenges in the scientific field.
