Supplier Selection and Evaluation by Fuzzy-AHP Extent Analysis: A Case Study RMG Sector of Bangladesh

The ready-made garments (RMG)is a rapid growing industry in Bangladesh and contributing significantly in the country’s economy. Effective supplier selection policy has significant strategic importance in the performance of such fast moving consumer goods industry. The supplier selection process is essentially a multi-criterion decision making problem which, therefore, must be developed systematically. Many models have been developed and proposed to find optimum solutions of this complex decision-making problem. Fuzzy Analytic Hierarchy Process (Fuzzy-AHP), which is a derived extension of classical Analytical Hierarchy Process (AHP),is an excellent method for deciding among the complex structure at different levels. In this paper an extent analysis of Fuzzy-AHP has been applied to evaluate and select the best supplier agency providing most satisfaction. The evaluation criteria are developed particularly for an RMG manufacturer in Bangladesh context and used successfully in the proposed model. A detailed implementation process is presented in this paper and finally the best supplier agency has been proposed from the outcome of the model

CAUSALITY BETWEEN EXCHANGE RATE AND ECONOMIC GROWTH IN BANGLADESH

This paper attempts to examine the relationship between Exchange Rate (ER) and Economic Growth (EG) proxied by Real Gross Domestic Product (RGDP) in Bangladesh for a period of 41 years ranges from 1973 to 2013 by using time series econometric technique. The empirical results show that there is a significant positive correlation between ER and EG. The results also advocate the presence of long-run equilibrium relationship between ER and EG. This is evidenced from Granger’s Causality Test that there is a bi-directional causality runs through ER to EG and EG to ER

Creek`s Aquaculture Techniques in Rangamati Hill Tracts of Bangladesh

An experiment was conducted in nine suitable (average .10±2 ha) creeks of Rangamati hill tracts Bangladesh viz., of Langadu, Naniarchar and Sadar Upazila for evaluating growth, survival and production performance of Indian major carps (Labeo rohita, Catla catla, Cirrhinus mrigala) in a completely randomized design into three different treatments with three replications for a period of one year. Stocking density, growth, survival was checked periodically and total yield calculated from stocking and harvesting data. A significant spatial variation in specific growth rate (SGR) and yields was found despite uniform stocking densities, attributable to variation in environmental parameters. Among the results rohu was found to have comparatively higher SGR of 1.51±0.55 in Naniarchar where as langadu creek was reported with higher SGR of 1.46±0.94, 1.57±0.41 and 1.46 ±.64 for rohu catla, and mrigal. Rangamati sadar Upazilla creek was found to be conducive to Catla with a SGR of 1.55±.78. In general, higher gross and net productions were reported from Sadar Upazilla, Langadu and Naniarchar creeks, suggestive of its suitability for developing creeks aquaculture technology. However research findings will help the community of Chittagong hill tracts by giving appropriate technology for sustainable fish production in creeks

Disparities in risks of malaria associated with climatic variability among women, children and elderly in the Chittagong hill tracts of Bangladesh

Malaria occurrence in the Chittagong Hill Tracts in Bangladesh varies by season and year, but this pattern is not well characterized. The role of environmental conditions on the occurrence of this vector-borne parasitic disease in the region is not fully understood. We extracted information on malaria patients recorded in the Upazila (sub-district) Health Complex patient registers of Rajasthali in Rangamati district of Bangladesh from February 2000 to November 2009. Weather data for the study area and period were obtained from the Bangladesh Meteorological Department. Non-linear and delayed effects of meteorological drivers, including temperature, relative humidity, and rainfall on the incidence of malaria, were investigated. We observed significant positive association between temperature and rainfall and malaria occurrence, revealing two peaks at 19 °C (logarithms of relative risks (logRR) = 4.3, 95% CI: 1.1–7.5) and 24.5 °C (logRR = 4.7, 95% CI: 1.8–7.6) for temperature and at 86 mm (logRR = 19.5, 95% CI: 11.7–27.3) and 284 mm (logRR = 17.6, 95% CI: 9.9–25.2) for rainfall. In sub-group analysis, women were at a much higher risk of developing malaria at increased temperatures. People over 50 years and children under 15 years were more susceptible to malaria at increased rainfall. The observed associations have policy implications. Further research is needed to expand these findings and direct resources to the vulnerable populations for malaria prevention and control in the Chittagong Hill Tracts of Bangladesh and the region with similar setting

Improvement of semen quality after treatment with folic acid and zinc in subfertile men in a tertiary hospital

Background: The 50% of all male infertility is idiopathic, and there is currently no recognized treatment. The effectiveness of a nonprescription nutraceutical comprising eight nutrients on sperm quality in males with idiopathic infertility was studied. The aim of the study was to evaluate improvement of semen quality after treatment with folic acid and zinc in subfertile men. Methods: This prospective observational study was carried out in the infertility unit, department of obstetrics and gynaecology, Bangabandhu Sheikh Mujib medical university (BSMMU), Dhaka, Bangladesh from January 2018 to June 2020. Approval from local ethics committee was obtained for this study.Results: One hundred and twenty-five male subfertile patients were included in this study. Most men, 99 (79.2%) belong to more than 30 years, followed by 26 (20.8%) less than 30 years, range was 25 to 50 years. Mean ± SD age was 35.3±5.1 years. Rapid linear (RL) before treatment were 16.06±14.46 (mean ± SD) and after treatment were 22.82±13.40 (mean ± SD). Slow linear (SL) before treatment were 17.56±12.06 (mean ± SD) and after treatment were 19.75±9.25 (mean ± SD). Non progressive (NP) before treatment were 10.82±8.95 (mean ± SD) and after treatment were 10.12±7.34 (mean ± SD). Morphology of the sperm before treatment were 19.43±15.48 (mean ± SD) and after treatment were 30.18±19.12 (mean ± SD).Conclusions:  Our research findings fully correspond to the above research results, so it can be said that treatment of subfertile men with micronutrients like folic acid and zinc sulfate causes increase of semen quality and thus plays a key role in treatment of male subfertility

XL-Sum: Large-Scale Multilingual Abstractive Summarization for 44 Languages

Contemporary works on abstractive text summarization have focused primarily on high-resource languages like English, mostly due to the limited availability of datasets for low/mid-resource ones. In this work, we present XL-Sum, a comprehensive and diverse dataset comprising 1 million professionally annotated article-summary pairs from BBC, extracted using a set of carefully designed heuristics. The dataset covers 44 languages ranging from low to high-resource, for many of which no public dataset is currently available. XL-Sum is highly abstractive, concise, and of high quality, as indicated by human and intrinsic evaluation. We fine-tune mT5, a state-of-the-art pretrained multilingual model, with XL-Sum and experiment on multilingual and low-resource summarization tasks. XL-Sum induces competitive results compared to the ones obtained using similar monolingual datasets: we show higher than 11 ROUGE-2 scores on 10 languages we benchmark on, with some of them exceeding 15, as obtained by multilingual training. Additionally, training on low-resource languages individually also provides competitive performance. To the best of our knowledge, XL-Sum is the largest abstractive summarization dataset in terms of the number of samples collected from a single source and the number of languages covered. We are releasing our dataset and models to encourage future research on multilingual abstractive summarization.

Micronutrients and Anaemia

Micronutrient deficiencies and anaemia remain as major health concerns for children in Bangladesh. Among the micronutrient interventions, supplementation with vitamin A to children aged less than five years has been the most successful, especially after distribution of vitamin A was combined with National Immunization Days. Although salt sold in Bangladesh is intended to contain iodine, much of the salt does not contain iodine, and iodine deficiency continues to be common. Anaemia similarly is common among all population groups and has shown no sign of improvement even when iron-supplementation programmes have been attempted. It appears that many other causes contribute to anaemia in addition to iron deficiency. Zinc deficiency is a key micronutrient deficiency and is covered in a separate paper because of its importance among new child-health interventions

Evaluation of current physical symptoms and psychological sufferings of patients during attending department of palliative medicine in a tertiary care hospital

Background: Empirical evidence indicates that anxiety and depression in cancer patients are often overlooked, leading to insufficient assistance for their psychosocial needs. Distinguishing between clinical anxiety and depression and the typical emotional distress post-cancer diagnosis can be challenging but holds significant implications for coping strategies and outcomes. The aim of this study was to assess current physical symptoms and psychological sufferings of patients’ during attending in a Palliative care department of a tertiary care hospital. Methods: This cross‐sectional study was conducted among 191 patients with cancer attending the department of palliative medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from November 2021 and March 2022. Data was collected by face‐to‐face interview using a structured questionnaire. Depression and anxiety were evaluated using a modified version of the primary care evaluation of mental disorders guide. Results: 47 participants (20.7% prevalence of depressive disorders and 13.9% prevalence of anxiety disorders) met the diagnostic criteria for at least one anxiety or depressive disorder, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The 95% confidence interval for these results was between 20.2 and 29.0. Conclusions: In summary, depression and anxiety disorders are prevalent among patients in palliative care, significantly reducing the quality of life for those facing cancer-related mortality

Towards global sustainability: Education on environmentally clean energy technologies

The recent climate change agreement in Paris highlights the imperative to aggressively decarbonize the energy economy and develop new technologies, especially for the generation of electrical energy that are environmentally clean. This challenge can only be addressed by a multi-pronged approach to research and education of the next generation of scientists and engineers as well as informed public discourse. Consequently this requires the introduction of new and comprehensive education programs on sustainable energy technologies for universities and, possibly, high schools. Among others, the new programs should provide in-depth knowledge in the development of new materials for more efficient energy conversion systems and devices. The enhanced level of education is also needed for properly assessing the competing technologies in terms of their economic and social benefits. The increasing recognition of the significance of clean and efficient energy conversion indicates the need for a comprehensive education program to be developed. The purpose of the present work is to consider the structure of both an education program and the related textbook where the energy-related fundamental and applied subjects are presented in a concentrated and uniform manner. Such a textbook could be an education aid for students of energy-related courses as well as the teachers involved in the formulation of the education programs. The textbook, which should be dedicated mainly for students at the undergraduate levels at universities, and possibly high schools, should include in-depth interdisciplinary sections dedicated to energy experts and graduate students. This paper considers the present international efforts in reducing the impact of climate change and the need to develop new technologies for clean energy generation. It is argued that progress in this area requires recognition of hydrogen as the main energy carrier of the future. This work also delineates the goals of the Sustainable Energy Network, SEN, involved in the UN program of Future Earth
