Ground Based Search and Rescue Operation during Cyclone Hazard in the Coastal Area of Bangladesh: A Disaster Management Perspective

Dr. Afzal Ahmed

Abstract: Bangladesh is frequently hit by many natural disasters, which cause tremendous damages to lives and properties. During severe cyclone in the coastal areas, timely and effective emergency response i.e., relief works and search and rescue (S&R) operations conducted by ground workers are greatly hindered due to the inaccessibility to the hit area. Sometimes it takes several days to gain access to some of the hardest-hit areas. On the other hand, aerial surveillance for S&R operations is also unsatisfactory due to lack of resources as well as of modern technologies. This paper discusses the existing approaches and associated problems of S&R operations during emergency response phase in the context of Bangladesh. Particular attention is given to the limitations of the spatial information acquired through conventional aircraft or satellite system. The limitations of such spatial information are evaluated in terms of temporal and spatial resolutions that are required for S&R operation. Finally, this research proposes a new tool for acquiring and processing geospatial information. Such tool is intended for strengthening ground-based emergency response which could be effectively utilized for timely and planned response.

POLYGYNY: A Misconception, Virulent and Formidable Misuse in Bangladesh

Md. Emran Parvez Khan, Anup Kumar Biswas, Mohammad Monir Hossen

Abstract: Polygyny has been an issue of widespread misunderstanding since laws and provisions regarding polygyny differ greatly throughout the world. Polygynous practices among the Muslims in Bangladesh are considered valid but at the same time an erroneous notion is spreading out in the country that Muslims are freely allowed to contract four marriages. In this article, an attempt has been made to clarify the justification of the issue. The article focuses on the development of polygyny from ancient period, the vision of Islam and the objectives for sanctioning polygyny. It also refers to the existing laws prevailing in the country and provides a comparative study with the laws and practices of other Muslim countries throughout the world. At the end of the article, recommendations have been made regulating the practice of polygyny in accordance with the present context of Bangladesh. The study of polygyny is mainly focused on misinterpreting the sense how the ordinary people misuse it. In the light of the objectives of the study, materials have been collected from different sources like enactments, books, journals, internet articles and case-laws. This is a short research because extensive fieldwork is not possible due to its nature. So it has been done in inductive method and it is concluded mainly with secondary information.


Critical Analysis of Soft Handover Performance in UMTS Cellular Network

Muhammad Golam Kibria, Dr. Sati McKenzie, Al-Imtiaz

Abstract: Comparing to conventional hard handover (HHO) in 2G system soft handover (SHO) in Universal Mobile Telecommunication System (UMTS) supports more than one connection simultaneously where a new connection is established before the first one is released. In SHO mode user establishes an extra connection with neighboring cell which enables the user to use the first connection with lower quality leads to decrease in interference level and hence increases system capacity. In this research paper several functionalities and performance of SHO have been analyzed. The relation between traffic load and coverage area as well as capacity has been analyzed. Performance of the system in terms of load interference in both SHO and HHO mode has also been analyzed. According to the analysis of the performance gained due to SHO implies that SHO is an evolution in UMTS cellular system.

Chloride Durability of Supplementary Cementitious Materials – An Electro Chemical Experimental Study

Syed Jamal Uddin Ahmed


Abstract: This paper describes how supplementary cementitious materials are resistant to chloride ingress when the concrete specimens were subjected to electro-chemical rapid chloride migration tests of two different kinds, namely, Potential Difference (PD) and Multi-Regime (MR) tests. Both the tests measure chloride durability in terms of D, the Coefficient of Chloride Diffusion. The concrete specimens were prepared with Portland cement partially replaced with fly ash, Ground Granulated Blast-furnace Slag (GGBS) and limestone filler and with varying w/c ratio. The PD and MR test results show that in the early ages, 100% Portland cement concrete performed well against chloride diffusion. However, fly ash and GGBS concrete showed higher resistance against chloride migration at later stage. At equal strength grade, w/c ratio and age, GGBS concrete had the highest resistance against chloride among other cement types.

A Study of Essential Oil Content of Cinnamomum Tamala (Tejpata)

Mohammed Jamil, Dr. Kaniz Sohana, Dr. Md. Shahjahan

Abstract: Cinnamomum Tamala1 leaf (Tejpata) is a popular spice of Bangladesh. Steam distillation of Tejpata gave 1-2% essential oil. The oil showed specific gravity of 1.002 at 32 OC and refractive index of 1.517 at 29 OC. It also showed an acid value of 5.3%; aldehyde value of 38.43%; ester value of 64.56%; phenol content of 78%; and alcohol value of 47.59%. The GC-MS analysis (Tejpata oil) showed that the major components of the oil were Eugenol (50.64%), α-phellandrene (5.97%) and γ-elemene (5.75%).


Implementation of a User-Friendly, Device Independent, Secure Key Deployment Technique for Sensor Nodes

Kishwar Ahmed, Samia Tasnim

Abstract: One of the most important steps in establishing wireless sensor networks is the deployment of cryptographic keys which, if compromised during initial key setup, could leave the network vulnerable and make it possible for attackers to access transmitted data. Message-In-a-Bottle (MIB), a user-friendly, secure mechanism for key setup on wireless sensor node serves the purpose of implementing cryptographic key on a sensor node; this mechanism relies heavily on metal ware instead of software. This paper focuses on different techniques of implementing cryptographic keys on sensor node, specially the MIB protocol. To the best of our knowledge there has been no such comparative study of these protocols. Additionally, we also focus on the weaknesses of the MIB protocol and propose possible improvements on those faults.

State of Primary Education in Bangladesh and Scope for Improvement

Mohit Prodhan, Mondar M. M. Ahmed

Abstract: Education is key to the overall development of a nation and primary education, upon which all higher education depends, deserves priority. This realization exists among the post independence government education policy makers of Bangladesh. Nonetheless, serious problems in the primary education system mar success achieved thus far. Education in Bangladesh is not internationally competitive and this has serious implications upon the overall progress of the nation. Lack of a unified curriculum has been the bane of the primary education sector for the past 40 years in Bangladesh. Other problems such as the quality of teachers and facilities, problems inbuilt within the syllabi and lack of political will to implement judicious recommendations of the different education commissions also have had ruinous effects. After decades of lagging behind the more developed countries in almost every sector, it is time to rise above political agenda and make objective analytical studies of the prevailing situation in the education sector and identify weaknesses for remedy. Such an initiative has been undertaken within the limited scope of this paper and several suggestions have been put forward. Through a strong primary education a highly qualified generation may emerge to lead Bangladesh in realizing the dreams and goals of the great Liberation War of 1971.


The Role of Financial Derivatives in Recent Capital Market Condition of Bangladesh

Md. Nazmul Hasan, Arif Rana, Nazia Nabi

Abstract: Derivatives instruments have been a feature of modern financial markets for several decades. They play a vital role in managing the risk of underlying securities such as bonds, equity, equity indices, currency, and short-term interest rate asset or liability positions. In the commodity markets, they have been around for a great deal longer. This study analyses the significance of introducing Derivatives in the capital market of Bangladesh for economic growth and to hedge risk and create overall liquidity in the stock market and above all to stabilize the Capital Market avoiding its unexpected crash.

Class Structure and Income Inequality in Contemporary Bangladesh: A Comparative Observation with China

Mr. Qin Guangqiang, Dr. Arifatul Kibria

Abstract: This article is the analysis of a comparative study between Bangladesh and China; here China provides a good reference system for our understanding of the social structure and income inequality in Bangladesh. To describe the class structure of contemporary Bangladesh and China by constructing the EGP class scheme under neo-Weberian theoretical point of view, 2005 Labor Force Survey data (LFS2005)of Bangladesh and 2005 General Social Survey data (CGSS2005) of China are respectively used in this article. On that basis, the article focuses on the decisive influence of class location on individual income. The study finds that class location not only directly influences individual’s source of income and the average income level of class groups but also structurally adjusts effects of individual characteristics ( Such as gender, age, education) on the income within class groups.

From Microcredit to Microfinance: Towards a More Sustainable Way of Poverty Alleviation.

Dr. Tazul Islam

Abstract: This paper explores the principles that could, and perhaps should be followed by the Microfinance Institutions (MFIs) when considering why and when microfinance works-and when and why it fails to achieve its promise of poverty alleviation. Taking the Grameen Bank (GB) of Bangladesh as a case study, this paper specifically examines microcredit’s poverty-alleviating ability and argues that microcredit has insurmountable limitations as a model of sustainable poverty alleviation. Developing client-responsive, flexible, and quality financial and skill-enhancing, non-financial services is imperative now. Thus, the more appropriate and higher the quality of services on offer, the better will be the impact on poverty alleviation.

Keywords:  Micro Credit, Grameen Bank, Poverty
