Software Defined 8, 16

Now-a-days digital circuits are getting more complex One IC in a digital circuit is used for a fixed purpose and its operation cannot be defined through software Because of this limitation digital circuit becomes larger in size When designing an 8bit digital circuit we do not include 16bit or 24bit components but this limits our scope of design and versatility of the design To overcome this problem an 8bit microcontroller is programmed which is able to do addition subtraction multiplication and 28 other digital operations in 8 16 24 bit level To add six 8 bit data 5 adder ICs are not needed anymore This IC can do it all alone For any logic operation the regarding mode needs to be selected in the same IC to perform desired operation It is software defined digital logic design IC This IC will save time space reduce cost in digital circuit designin

Ownership structure and firm performance: Evidence manufacturing companies listed in Dhaka Stock Exchange

Purpose: This study aims at examining the relationship between ownership structure and firm performance about manufacturing companies listed in Dhaka Stock Exchange (DSE). Research Methodology: The analysis empirically uses dynamic panel data from 15 pharmaceutical and chemical companies enlisted in Dhaka Stock Exchange (DSE). The study period was 2011-2020. The study used panel data regression analysis. Results: The study confirms that sampled companies' financial performance represented by ROA and ROE is significantly influenced by institutional ownership, ownership concentration, and foreign ownership whereas, negatively influenced by managerial ownership and insider ownership. The study didn't find any noteworthy association between block holders' ownership with firms' performance. Contribution: This study keeps a significant role in understanding the ownership structures’ influence on firms’ performance. More specifically the policymakers may consider the study for implementing the relevant issues. Limitations: The study's results were restricted to 15 Bangladeshi pharmaceutical and chemical companies enlisted in DSE and could not be applied to other companies doing business in Bangladesh

Determinants of Users’ Satisfaction Regarding Mobile Operators in Bangladesh: An Exploratory Factor Analysis Approach on University Students

Customer satisfaction is an important issue in current marketing field. This paper basically prepared based on 444 respondents (University Students) to understand which factors make them most satisfied toward their using cell phone operator’s service. Five major cell phone operators (Grameenphone, Banglalink, Robi, Airtel, and Teletalk) have been picked up along with 28 service items (Such as call charge rate, network facility, various offers, balance transfer system etc.) The study is conducted by factor analysis to identify the major factors that influencing users’ satisfaction. The study attained 7 factors as-Various Offers, Charge Rate, Digital Services, Internet Services, Recharge Facilities, Network Coverage and Customer Care Services. The study reveals that users (University Students) have more emphasis on various offers. The findings confirmed that Various Offers, Charge Rate, Digital Services, Internet Services, Recharge Facilities, Network Coverage and customer Care Services contribute strongly to generating customer satisfaction. From the study cell phone operators of Bangladesh can get a specific view about the factors that directly influence customer satisfaction especially the University students’ demands. Keywords: Users’ Satisfaction, Cell Phone Operators, Factor Analysis, Banglades

Academic Use of Smartphones in Secondary Level Education in Bangladesh: A Non-Parametric Approach

This study aims to examine the use of smartphones for educational purposes and the acceptance of online learning among secondary students. To investigate the academic utilization of smartphones among secondary students in Bangladesh, a sample of 384 students from different districts of Bangladesh were surveyed. The survey was conducted using a selfadministered, semi-tailored computerized questionnaire. The collected data was analyzed using IBM SPSS statistics 26 and the Mann-Whitney U test. The findings indicate that male students used smartphones for educational purposes with greater confidence and less difficulty than female students. On the other hand, students in 8th to 10th grade classrooms reported a greater willingness to use smartphones for academic purposes, with urban students being more enthusiastic than their rural peers. The study’s findings have implications for the government, policymakers, educators, and non-governmental organizations (NGOs). They highlight the importance of ensuring equal access to resources and tools that support academic success, as well as addressing the adverse effects of excessive smartphone usage. In addition, the government and NGOs should prioritize the elimination of inequities between rural and urban areas and provide subsidies to rural students

Performance of a hermetic device and neem (Azadirachta indica) in storing wheat seed: Evidence from participatory household trials in central Bangladesh

Smallholder farmers in Bangladesh often use low-density polyethylene (LDPE) bags contained within woven polypropylene bags to store wheat seed during the summer monsoon that precedes winter season planting. High humidity and temperature during this period can encourage increased seed moisture and pests, thereby lowering seed quality. Following a farm household survey conducted to inform trial design, eighty farmers were engaged in an action research process in which they participated in designing and conducting trials comparing traditional and alternative seed storage methods over 30 weeks. Factorial treatments included comparison of hermetic SuperGrainbags® (Premium RZ) against LDPE bags, both with and without the addition of dried neem tree leaves (Azadirachta indica). SuperGrainbags® were more effective in maintaining seed moisture at acceptable levels close to pre-storage conditions than LDPE bags. Both seed germination and seedling coleoptile length were significantly greater in hermetic than LDPE bags. Neem had no effect on seed moisture, germination, or coleoptile length. SuperGrainbags® were also more effective in abating seed damage during storage, although inclusion of neem within LDPE bags also had significant damage. Quantification of seed predating insects and diseases suggested that SuperGrainbags® also suppressed Coleopteran pests and blackspot, the latter indicative of Fusarium graminearum. Conversely, where farmers used LDPE bags, neem also had an additional though limited pest suppressive effect. Post-storage treatment scoring by farmers revealed a strong preference for SuperGrainbags® and no preference differences for or against neem. This study demonstrates a process by which farmers can be involved in the participatory co-design and testing of alternative wheat storage options, and stresses the need to develop SuperGrainbag® supply chains so hermetic storage can be made widely available

Exploring barriers to accessing healthcare services for older indigenous people in the Chittagong Hill Tract, Bangladesh

We aim to investigate the obstacles faced by elderly indigenous individuals in the Chittagong Hill Tracts, Bangladesh when accessing healthcare services. A qualitative research approach was utilized, and data collection was carried out in three distinct regions of the aforementioned area. A total of 30 in-depth, semi-structured interviews and participant observations were conducted to achieve the research objectives. Thematic analysis utilizing both a deductive and inductive approach was employed to analyze the data. The Granheim method and Nvivo-12 software were utilized to process, analyze and code the data. The study's findings indicate that a lack of knowledge about healthcare needs, geographical barriers, poor financial conditions, higher cost of medical services, scarcity of hospitals nearby and communication barriers all contribute to inadequate access to healthcare services. By recognizing the factors that impede access to healthcare services in this region, this study offers valuable insight for policymakers and healthcare providers on how to enhance healthcare services for the indigenous population, especially the elderly. Furthermore, the government can adopt a more efficient approach to include these elderly individuals in various social safety net programs
