Item EXPERIMENTAL INVESTIGATION ON THE IMPACT OF CONCRETE STRENGTH ON THE DUCTILITY OF REINFORCED CONCRETE FRAME STRUCTURES(R&D Wing, MIST, 2019-12) Golam Kibria, Lieutenant Colonel Bhuiyan MohammadThis experiment was undertaken to study the impact of concrete strength on the ductility of reinforced concrete frame structure. Two half scale interior joint with monolithic transverse beams and slab from a six storied residential building were selected for the experiment. The joints were constructed without any shear reinforcement within the joint region to evaluate the contribution of concrete strength in bond stress between the longitudinal reinforcement and concrete. Bond stress has important specific roles on the ductility of the joint in particular and on the ductility of the global structure in general. The models were subjected to incremental static cyclic lateral loading provided by hydraulic jacks under constant axial loading. Deflections and rotations were measured by dial gauges and a video extensometer. It is found from the study that ductility of the structural members i.e. beams, columns and joints increased remarkably with increased concrete strength.Item SPATIAL ANALYSIS OF THE INTEGRATION CORE OF COMILLA CITY CORPORATION AREA AND THE IMPACT OF THE BY-PASS ROAD - A SPACE SYNTAX ANALYSIS(R&D Wing, MIST, 2019-12) Hossain Mou, Ishrat ZerinUrban area changes according to different uses of space and movement with the passage of time, as seen in land use, road network etc. Urban morphological transformation constantly remains under succession. The urbanization process substantially increases the demand for urban services such as transport, on whose efficiency and availability, the successful and continued existence of urban society depends. Transportation has a strong influence on the spatial structure at the local, regional and global levels. Historically, both social and economic growth within civilizations, have been structured by routes of travel. Thus, it is not surprising that a city’s circulation system has become an important facet in today’s communication-oriented urban life. Adequate transportation facilities are vital to promote growth, manage the effects of development and protect and improve city’s quality of life. The paper is intended to analyze the present land uses of Comilla city (area under the newly formed City Corporation) by drawing axial lines over the collected base map and identify the integration core of the city, in relation to the introduction of the Dhaka – Chittagong by-pass road. The town though facing tremendous pressure of haphazard development, has the scope for suggested and designed development through rigorous surveys and analytical methods using space syntax analysis. This study helps to assess the spatial impact of introducing a by-pass road on the existing physical city in relation to its functional organization.Item ORGANIZATION AND MANAGEMENT PRACTICES OF UNIVERSITY LIBRARIES IN BANGLADESH: AN EVALUATION(R&D Wing, MIST, 2019-12) Sanaullah, Lieutenant Colonel Muhammad; Uddin, Md. MoslemThis article provides an overview of the university libraries and explains in detail their various organizations, management, collections, functions, systems, and services as a whole. It also profiles careers in library work, the education of librarians, and several professional organizations for librarians. Academic libraries function almost as the hearts in the academic activities of the University. The libraries perform their functions properly, a body of knowledge has been developed and incorporated within the scope of the training programs in library management. That’s why a qualified librarian is needed to meet up such requirements. It is quite impossible to control the entire library in pen and paper where there are a huge amount of books for the librarian. A librarian (he/she) has to serve not only a single job, but also multiple jobs simultaneously. That’s why it is difficult to keep track of those jobs. Library management is the theoretical concepts of managing such a library efficiently. Finally, the article describes contemporary library management in various university libraries in Bangladesh.Item APPLICATION OF SPACE SYNTAX ANALYSIS IN LALBAGH Exploring The Links Between Spatial Analysis And Drug Crime Pattern In Selected Streets Of Lalbagh, Dhaka(R&D Wing, MIST, 2019-12) Ahmed, SabbirDrug crime is an urban problem, and in Lalbagh, its occurrence is fairly common. It can nevertheless be prevented with surveillance, a feature of urban design. Spatial studies and criminology enable us to know significantly about where and why crime occurs. Criminals are rational individuals and they weigh risks and opportunities. A direct correlation can thus be found between the following variables: 1. Risk & Opportunity and 2. Physical Implications of Urban Design which includes spatial attributes. The aim of this paper is to identify the spatial attributes of a major drug crime location (Lalbagh) for helping urban planners, designers and crime control authorities to identify crime zones easily for acting “proactively” rather than “reactively” to the crime. While designing or examining neighbourhoods, for high values of Integration, Integration R=3 and Integration R=10 and Connectivity of an area, we can predict that area to be less crime-prone; because with higher levels of movement, levels of co-presence and co-awareness are expected to be higher. Based on this principle, selected streets of Lalbagh have been studied. Out of the other smaller streets of Lalbagh, Road 10, Shahidnagar was found to be particularly prone to criminal activities and this paper is focused on finding out the reasons behind it, on the basis of space syntax analysis. Depthmap software has been used as a tool to analyze and explain this pattern of drug crime.Item LOCAL RESIDENT’S ATTITUDES TOWARDS THE IMPACT OF TOURISM DEVELOPMENT: A STUDY OF SAINT MARTIN ISLAND, BANGLADESH(R&D Wing, MIST, 2019-12) Miah, Masum; Mawa, Mst.

The study is based on a total number of 20 commercial banks and total 120 respondents consisting the bank owners. This study is an outcome of both the primary and secondary data. The requisite primary data were collected using structured questionnaire. The main objective of this study is to critically evaluate the role of sustainable finance in the growth and development in the banking industry in Bangladesh. This study reveals that the levels of perceptions of the most of the respondents were found to be very high in terms of their awareness, beliefs, attitudes and understanding as regards the dimensions of sustainable finance viz. customers’ satisfaction, employees’ welfare, contribution to govt. exchequer, generating revenues, cost savings, products or services with rescannable charge, brand awareness and addition to capital and the shareholders’ equity representing value of the firm was found to be influenced to the extent of 41.6 percent by the relevant independent variables representing sustainable finance of the sample banks. The major suggestions for addressing challenges put forward by the respondents have been loan sanctioning founding on proper appraisal of loan applications and improving operational efficiency. The relevant bank authorities should implement the suggestions in order to improve the sustainable finance related factors.Item ACCOUNTING INFORMATION SYSTEM (AIS) PRACTICES AND ITS EFFECTS ON SMES: THE BANGLADESH HANDLOOM INDUSTRY EXPERIENCE(R&D Wing, MIST, 2019-12) Hossain, Md. Ismail; Rahman PhD, Major Md. FerdausurThe study is aimed to identify the scenario of practicing the Accounting Information System (AIS) by Benarashi, Jamdani, Reshmi, Shari, Lungi and Gamcha producing Handloom industry of Bangladesh. A qualitative research design was employed and a non-probability sampling design in the form of a convenience sampling method was employed to gather the data. Data were drawn from both primary and secondary sources. Primary data was drawn from 30 small-scale Shari-Lungi producers, 5 each from Pabna, Sirajgonj, Tangail , Dhaka , Narayangonj, and Narshingdi of Bangladesh by administering semi-structured questionnaires through personal interviews. There are many perceived factors affecting their adoption of accounting information system practices and their effects on their business operations in the area. Among such factors include; lack of adequate knowledge and training, willful misconduct, and negligence from owners as well as controlling authority part. It is also revealed that, all levels of employees are ignorant about the use of Accounting Software; rather they try little to keep accounting records manually. It was also found that accounting illiteracy is the root cause of that. It was concluded that the lack of accounting knowledge and skills may in future threaten the financial steadiness of the Handloom Sector. In sustaining the sector, the findings recommends operators to undergo basic accounting training as well as Accounting Software training to acquire relevant knowledge and skills, employ qualified accounting information systems personnel and providing them with good motivational packages to ensure that their efficiency and morale is enhanced and, maintain strong internal control to check the practice of misappropriating funds in the business.Item ASSESSMENT OF FUTURE WATER DEMAND OF DHAKA CITY(R&D Wing, MIST, 2019-12) Haque, Lieutenant Colonel Md EhsanulDhaka, the capital of Bangladesh, is one of the fastest growing cities of the world. It remains a great challenge to ensure uninterrupted water supply in the city with adequate quantity and quality round the year. Necessary measures are undertaken to meet the growing demand of water supply which is presently dependent on abstraction of groundwater. It appears that no further abstraction is feasible as the groundwater level is declining very fast. To reduce the overwhelming dependence on groundwater resources, surface water in the vicinity of the Dhaka city can be utilized. The study includes water demand and population projection upto 2035.Item BEHAVIOR OF CONCRETE FILLED STAINLESS STEEL TUBULAR COLUMN UNDER AXIAL LOADS(R&D Wing, MIST, 2019-12) Sanaullah, Lieutenant Colonel Muhammad; Rahman, Jesika; Ibrahim, Ibriju; Rahman, Major Md.
