Teaching Performance of Primary School Teachers and its Impact on Students’ Academic Achievement in Bangladesh.

The study mainly dealt with the teaching performance of primary school teachers and its impact on students’ academic achievement in Bangladesh. It reveals the teaching performance of teachers considering five important indicators. The academic achievement was also looked into account examining the five important indicators. Social survey method was adopted and both primary and secondary data were used. Data were collected through questionnaire and interviews. Sample was taken randomly and the total number of sample was 120. 60 teachers of govt. and 60 teachers of non-govt. primary schools were taken to make a comparison. 15 Govt. and 15 non-govt. primary schools were taken to assess the policy implementation including other formal activates. The study has found that there are some lacks of teachers in performing their duties. For this reason, the academic achievement of the students’ is not satisfactory in both of the govt. and non-govt. primary schools. Comparatively the performance of govt. primary school teachers is more satisfactory than non-govt. primary school teachers in Bangladesh. So, the students’ academic achievement is low as to the expectation in both of the govt. and non-govt. primary schools.

安定流路の形成に関する研究

発展途上諸国においては社会経済や河川環境の観点から、現地調達可能でかつ安価な材料を用いた河道の安定化工法が好ましい。本報告では、その方策の一つとしてバンダルをとりあげ、その機能評価を行った。すなわち、移動床模型水路を用いてバンダル上部工(不透過型水制)の水刎ね効果による澪筋の形成およびバンダル下部工(透過型水制)の土砂制御効果による側岸への土砂堆積について検討するとともに、バンダル周辺部での局所洗掘および澪筋部の河床低下を評価し得る解析モデルを開発し、水理実験結果をもとにモデルの妥当性を検討した。その結果、本解析モデルにより、実験結果が比較的良好に説明し得ることが判明した。なお、比較のため、不透過型水制および下部工を有しないバンダルについても検討している。さらに、バンダルを長期的に用いることにより安定河道を形成する方法についても概念的に検討している。As an alternative low cost method that can be adaptive within local socio-economic andenvironmental condition, the possibility of use of bandals for the formation of stable river course isexplored. The basic features of bandals in terms of flow and sediment control are clarified usingsimplified mobile bed experiments. Based on experimental results, simplified analytical models forthe prediction of main channel degradation and local scouring around the structures are developedand verified using experimental data. The model predicts the experimental results reasonably well.Finally, the concept of gradual method for river course stabilization is discussed on long-term basis.発展途上諸国においては社会経済や河川環境の観点から、現地調達可能でかつ安価な材料を用いた河道の安定化工法が好ましい。本報告では、その方策の一つとしてバンダルをとりあげ、その機能評価を行った。すなわち、移動床模型水路を用いてバンダル上部工(不透過型水制)の水刎ね効果による澪筋の形成およびバンダル下部工(透過型水制)の土砂制御効果による側岸への土砂堆積について検討するとともに、バンダル周辺部での局所洗掘および澪筋部の河床低下を評価し得る解析モデルを開発し、水理実験結果をもとにモデルの妥当性を検討した。その結果、本解析モデルにより、実験結果が比較的良好に説明し得ることが判明した。なお、比較のため、不透過型水制および下部工を有しないバンダルについても検討している。さらに、バンダルを長期的に用いることにより安定河道を形成する方法についても概念的に検討している。As an alternative low cost method that can be adaptive within local socio-economic andenvironmental condition, the possibility of use of bandals for the formation of stable river course isexplored.

Exposure to secondhand smoke is associated with poor sleep quality among non-smoking university students in Bangladesh: a cross-sectional survey

Abstract Although secondhand smoke (SHS) exposure is predominant in Bangladesh, the adverse effect of SHS exposure on health-related behaviors, such as sleep quality, have remained an under-investigated area of the country’s public health landscape. Therefore, the purpose of this study was to examine the association between SHS exposure and poor sleep quality among non-smoking university students in Bangladesh. A cross-sectional survey was carried out between May and September 2022. SHS exposure (main predictor variable) and other covariates (e.g., age, sex, etc.) were measured using a self-reported questionnaire and sleep quality (outcome variable) was measured via the Pittsburgh Sleep Quality Index. Multiple logistic regression models investigated the association between SHS exposure and poor sleep quality. The study included 390 students (mean age: 22 years, 53.8% male). Approximately 41.8% of the participants reported SHS exposure, and 50.5% had poor sleep quality. Students exposed to SHS were more likely to have poor sleep quality compared to their counterparts (AOR = 1.61; 95% CI 1.01, 2.58). Subgroup analysis revealed poor sleep quality was 2-times higher among male students exposed to SHS than those male students without SHS exposure (AOR = 2.03; 95% CI 1.05, 3.93). No association was found in female students. Findings from this study warrant increased awareness and public health initiatives on the implications of SHS on health behaviors, such as sleep quality, in non-smoking Bangladeshi university students

Assessment of food safety knowledge, attitudes and practices of street food vendors in Chattogram city, Bangladesh: A cross‐sectional study

Abstract Introduction Street food has become popular in developing countries due to its affordability, availability and taste. Maintaining the quality and safety of street food is linked to the vendors’ appropriate food handling practices to reduce foodborne illness. Therefore, this study aimed to assess food safety knowledge, attitudes and practices of street food vendors in Chattogram city, Bangladesh. Methods A cross‐sectional study was carried out among 302 street food vendors from December 2020 to March 2021. Data were collected by in‐person interviews through a structured questionnaire. Independent sample t‐tests and one‐way analysis of variance (ANOVA) were used to compare food safety knowledge, attitudes, and practices scores across socio‐demographic variables. Results The mean score of food safety knowledge, attitudes and practices was 8.99 (SD = 4.17, range: 1–18), 8.46 (SD = 3.51, range: 1–16) and 17.78 (SD = 5.74, range: 1–34), respectively. The food safety knowledge scores significantly (p < 0.05) differed by the participants’ age, marital status, income, residence and work experience. The average food safety attitudes score significantly (p < 0.05) varied by age, marital status, income, and education level. The average food safety practices score significantly (p < 0.05) differed by the respondents’ education level and work experience. Conclusion Our findings suggest that food safety knowledge, attitudes, and practices were poor among street food vendors. Therefore, there is a need for strategies and intervention programs such as food safety training and awareness campaigns as well as financial support to improve food safety knowledge, attitudes, and practices which help to reduce foodborne illness

Prevalence and predictors of binge eating disorder symptoms among a sample of university students in Bangladesh: A cross‐sectional survey

Abstract Background and Aims There is a dearth of information about binge eating disorder (BED) among Bangladeshi university students, who may be more susceptible to BED due to the rise in unhealthy lifestyles and food habits. Therefore, the purpose of this study was to assess the prevalence and associated factors of BED symptoms among Bangladeshi university students. Methods Students (N = 525) from three public universities in Bangladesh participated in this cross‐sectional study between November 2022 and March 2023. Face‐to‐face interviews were conducted using a structured paper‐based questionnaire that included two validated survey tools; the binge eating disorder screener and the patient health questionnaire‐9. To identify the factors associated with BED symptoms, multiple logistic regression analysis was conducted, with sociodemographic and behavioral information (e.g., age, sex, smoking status, etc.) considered as covariates. Results The prevalence of BED symptoms among participants (mean age 21.28 years, 50.3% male and 49.7% female) was 20.6%. Male students had a 2.28 times higher likelihood of having BED symptoms compared to female counterparts (adjusted odds ratio [AOR] = 2.28; 95% CI: 1.33−3.89). Older students (AOR = 3.56, 95% CI: 1.80−7.05), students who were overweight or obese (AOR = 3.32, 95% CI: 1.87−5.89), and students reporting higher depressive symptoms (AOR = 2.69, 95% CI: 1.66−4.35) were at greater risk for developing BED compared to their respective counterparts. Conclusions This study provides new insights into the prevalence of BED symptoms and its contributing factors among Bangladeshi students. Approximately 1‐in‐5 university students reported having BED symptoms. University students who are older, overweight, or obese, and who report depressive symptoms may be at greatest risk. Future longitudinal studies are needed to determine the causal factors underlying BED. Findings from this study can assist policymakers and public health professionals in developing effective and targeted strategies to mitigate the risks associated with BED among Bangladeshi university students
