Development of the Student Management System (SMS) for Universities in Bangladesh
(BGMEA University of Fashion and Technology, 2014) Barua, Biman; Obaidullah, Md.
A great number of higher educational institutions are currently operational in Bangladesh and every year more are entering the market. Higher educational institutions are big places with many people involved and countless operations take place at all times. Traditionally, operations and transactions in such places are handled by paper based forms and systems. However, as the daily increase of places and human population; managing large organizations such as universities with pen and paper are becoming quite troublesome and are leading to tremendous amout of mistakes and mismanagements. Long ago, developed countries addressed this issue and ever since they have been using computers and information technology to handle such organizations effectively. However, in countries like Bangladesh, those solutions are not yet widely implemented; and therefore handling large organizations manually is becoming next to impossible. Only few universities in Bangladesh are using computerized automated systems to manage university activities. This work attempts to find out the statistics about the automated systems uses in the higher educational institutions in Bangladesh and also proposes a methodological automated system framework called Student Management System (SMS) that can replace the less efficient traditional system. Here, we tried to accommodate everything for a student from entering the university, to graduate and then to remain in the alumni association as well as other possible functionalities for the university management to serve the students better and to execute university tasks painlessly.
Effect of Sowing Times on Growth and Yield of Blackgram (Phaseolus Mungo L.)
(University of Rajshahi, 2011) Obaidullah, Md.; Alam, Md. Zahangir
An experiment was conducted to study the effect of sowing times on growth and yield of blackgram (Phaseolus mungo L. ). Four varieties of blackgram viz., BARIMASH-1, BARIMASH-2, BARIMASH-3 and LOCAL VARIETY B-10 were used in the study. Seeds were sown on four different sowing times viz., 01 August (S1 ), 11 August (S2), 21 August (S3 ) and 31 August (S4) over two seasons during the kharif-2 monsoon under field conditions. The S3 (21 August) plants had the highest TDM than the other sowing and LOCAL VARIETY B-10 showed the highest TDM at all the sowings. Leaf area index (LAI) and leaf area duration (LAD) at most of the growth stages were found the highest in S1 (01 August) in both the years. Among the varieties, the highest LAI and LAD were observed in LOCAL VARIETY B-10 in both the years. CGR, RGR, RLGR, NAR, SLA and L WR at most of the stages were observed higher values in S3 plants (21 August sowing) whereas higher values in LAR was found in SI of all the sowings and varieties in both the years. The highest values of CGR, RGR, RLGR, LAR, SLA and L WR were found in LOCAL VARIETY B-10 whereas NAR showed better performance in BARIMASH-3 variety in both the years. Therefore, most of the growth attributes were higher in S3 (21 August sowing) and LOCAL VARIETY B-10 in both the years. Among the growth attributes, TDM, LAI, LAD and CGR increased with increasing plant age and then decreased gradually in both the years. Again, RGR, LAR, RLGR and L WR declined with increasing plant age. With few exceptions, NAR showed increasing tendency towards the later stages of growth. Only SLA showed increasing tendency at the middle stages of growth in both the years. At the early growing periods, mean air temperature (maximum and minimum) were higher and then declined upto the final harvest. So, S1 (01, August) had the highest air temperature and the lowest in S4 (31, August) than that of the middle growth stages in both the years. The lowest sunshine hours were observed during SI growing period and the highest in S4 in both the seasons. Significant sowing time and varietal effects were found for most of the phenological characters in both the years. Most of the phenological characters were observed higher values in S4 sowing (31 August) followed by the optimum sowing S3 (21 August) and showed their highest values in LOCAL VARIETY B-10. Days taken for attainment of most of the phenological stages were higher in S3 and LOCAL VARIETY B-10 required the highest number of days for attaining the different phenological stages. The requirement of heat units (GDD) at all the stages were significantly higher in S4 followed by S3 The LOCAL VARIETY B-10accumulated the highest heat unit (GDD) at most of the stages for all the sowings. The requirement of helio-thermal unit (HTU) at most of the stages were highest when the crops were sown in S4 (31 August) followed by S3 . HTU was observed higher values in LOCAL VARIETY B-10 of all the sowings at most of the stages. Pheno-thermal indices (PTI) during the different phenological stages were highest in S4 followed by S3 in both the years. At all the stages, PTI values were highest in BARIMASH-3. The plants of S3 used heat more efficiently than the other sowings and the highest HUE was observed in LOCAL VARIETY B-10 which was followed by BARIMASH-2 in both the years. Sowing time was always significant for chlorophyll a, b and total chlorophyll and chlorophyll a:b ratio and significant varietal effect was observed for chlorophyll b of matured green leaves. The SI plants ratio was observed for highest in S4 than the other sowmgs and BARIMASH-1 produced the highest chlorophyll a, b and total chlorophyll and LOCAL VARIETY B-10 produced be highest chlorophyll a: b ratio in both the years. The highest RLWC was recorded in S1 plants at 8.00 a.m. For all the sowings, it was higher at the morning (8.00 a.m.) and got reduced at 12.00 noon and showed some recovery at the afternoon (4.00 p.m.) in both the years. The highest RL WC was observed in BARIMASH-3 followed by LOCAL VARIETY B-10 at 8.00 a.m. and lowest in BARIMASH-2 for most of the cases in both the years. Among the yield and yield components, significant sowing time and varietal effects were observed at most of the characters in both the years. Most of the yield characters were found higher in S3 (21 August) sown crops in both the years. Among the varieties, most of the characters showed their higher values in LOCAL VARIETY B-10 followed by BARIMASH-3 in both the years respectively. Simple correlation co-efficient between yield and yield components indicated that grain yield of all the sowings was positively correlated with total dry matter (TDM) planf1, pod no. planf1, pod dry weight planr1, grain no. planf1 and grain weight planf1 except 3rd sowing whereas it was negatively associated with 100-seed weight and harvest index. It was suggested that for better growth and yield performances, seeds of blackgram should be sown on 3rd week of August (21 August) in the northern part of Bangladesh. LOCAL VARIETY B-10 may be considered as more widely adapted variety for this region.

"Background: In Bangladesh, remittances constitute a substantial portion of the country's foreign exchange earnings and serve as a primary source of income. However, a considerable number of Bangladeshi citizens reside overseas without proper documentation, exposing them to significant challenges such as limited access to healthcare and socioeconomic opportunities. Moreover, their irregular migration status often results in engaging in risky health behaviors that further exacerbate their vulnerability. Hence, this study aimed to investigate the risky health behavior and HIV/STI susceptibility of Bangladeshi irregular international migrants residing across the globe with undocumented status. Methods: Using a qualitative Interpretative Phenomenological Approach (IPA), 25 illegal migrants were interviewed who are currently living illegally or returned to their home country. The author used a thematic approach to code and analyze the data, combining an integrated data-driven inductive approach with a deductive approach. Concurrent processing and coding were facilitated by employing the Granheim model in data analysis. Results: The study identified four risky health behaviors among irregular Bangladeshi migrants: hazardous living conditions, risky jobs, suicidal ideation, and tobacco consumption. Additionally, the authors found some HIV/STI risk behavior among them including engaging in unprotected sex, consuming alcohol and drugs during sexual activity, and having limited access to medical facilities. Conclusions: The findings of this study can be used by health professional, governments, policymakers, NGOs, and concerned agencies to develop welfare strategies and initiatives for vulnerable undocumented migrant workers."

In recent times, global student migration has been growing rapidly, including an increase in student migration from Bangladesh. However, the field of student migration from Bangladesh remains relatively neglected in migration research. Hence, this study aims to explore the factors which influence Bangladeshi students in their migration decision. This study employed a qualitative research design to investigate the research questions. Specifically, the data collection involved ten focus group discussions with university students in Bangladesh. Subsequently, the researchers conducted a thematic analysis of the data using the Granheim approach, which involved identifying patterns and themes in the data. The NVivo 12 software was utilized to facilitate the analysis. The present study employs the push–pull theory to shed light on the determinants of student migration decisions. The research findings elucidate the salience of push factors, such as corruption, discrimination, lack of good governance, political instability, and limited freedom of expression, which potent motivators students to leave their home countries. In contrast, the study identifies various pull factors that attract students to settle abroad, including better living standards, economic opportunities, as well as career advancement and social value that impact migration choices. The study outcomes have crucial implications for policymakers, stakeholders, and the Ministry of Education to formulate appropriate policies in this domain.

(2023-09-15) Obaidullah, Md.; Hossain, Meherab; Raihan, Md. Showkat; Hossen, Md. Sohrab
The humanitarian response and refugee crisis are two of the most pressing global issues today. The Rohingya refugee crisis, in particular, is crucial for global peace, but it has also placed a significant burden on Bangladesh. Although the government initially framed the response as a humanitarian one, this study examines the shift in perception of the crisis from a humanitarian issue to a burden for the host country. The study is qualitative in nature and aims to explore the narrative transformation of Rohingya refugees from aid beneficiaries to a burden for Bangladesh. The study was based on secondary data, using critical discourse analysis. To explore the factors behind the transformation, we employed integrated threat theory. The findings of this article indicate that the community’s support for Rohingya refugees has turned to hostility, and economic, political, environmental, cultural and security risk factors have contributed to the Rohingya refugee crisis in Bangladesh becoming a burden. This study will be valuable for understanding how perceptions of a humanitarian crisis can change over time and the various factors that contribute to this shift. It will also provide insight into the challenges faced by host countries in managing refugee crises and the importance of addressing these challenges to ensure that the crisis remains a humanitarian issue and not a burden for the host country.
