Abstract. This literature review paper discusses the proper use of qualitative research methodology to discuss several research aspects for the improvement of the readers' skill. During the last few decades, the use of qualitative research has been increased in many institutions. It can be used to explore several areas of human behavior for the development of organizations. The purpose of this study is to provide inspirations to the new researchers for the development of their qualitative articles. The paper analyzes the design of qualitative research giving some methodological suggestions to make it explicable to the reader. In thispaper, an attempt has been taken to study the background of the qualitative research methodology in social sciences and some other related subjects, along with the importance, and main features of the study.

Abstract

Research is the framework used for the planning, implementation, and analysis of a study. The proper choice of a suitable research methodology can provide an effective and successful original research. A researcher can reach his/her expected goal by following any kind of research methodology. Quantitative research methodology is preferred by many researchers. This article presents and analyzes the design of quantitative research. It also discusses the proper use and the components of quantitative research methodology. It is used to quantify attitudes, opinions, behaviors, and other defined variables and generalize results from a larger sample population by the way of generating numerical data. The purpose of this study is to provide some important fundamental concepts of quantitative research to the common readers for the development of their future projects, articles and/or theses. An attempt has been taken here to study the aspects of the quantitative research methodology in some detail.

Knowledge is mainly divided into two types: tacit and explicit. The purpose of this study is to examine the concept of tacit knowledge and the application of it for the development of organizations. It is evident that tacit knowledge has a strong connection with the research area of knowledge management. The present global economy is tacit knowledge based for the sustainable development. Since it is very complex in its nature, therefore acquire and extract of tacit knowledge is not a very easy task. It is unwritten, unspoken and hidden vast storehouse of knowledge of a person. It stresses on the success and well-being of humankind. It is obtained as a result of the direct interaction between individuals and their environments. The paper analyzes the importance of tacit knowledge for the sustaining of the long-term capabilities and performance in organizations. An attempt has been taken here to discuss sharing of tacit knowledge in organizations. This paper also tries to explore the properties of tacit knowledge in some detailed.

Myanmar is a resource-rich country especially in oil and gas. The country is involved in ethnic conflicts since its independence in 1948. Recently violation of human rights against the Rohingya Muslims become severs. The main cause of Rohingya crisis is a question about its origin. Rakhine (or Arakan) is a State located in the west coast of Myanmar. The population of Arakan State is largely agrarian and more than 43.5% live below the poverty line. The Rohingya, a Muslim ethnic minority group in Rakhine, consider as the most persecuted, vulnerable, and oppressed minorities around the globe. Recently, the persecution on Rohingya Muslims has increased due to Buddhist nationalism in Myanmar. Rohingyas are continued to suffer from several forms of restrictions and human rights violations in Myanmar due to deny Myanmar citizenship. They are victim of various oppressions, such as, arbitrary taxation, land confiscation, destruction of mosques, torture and ill-treatment, extrajudicial executions, restrictions on movements, forced eviction and house destruction, forced laborers on roads and at military camps, and financial restrictions on marriage.  Oppression on Rohingya started since 1962, when General Ne Win took power of Myanmar after a coup. Since the 1970s, a number of crackdowns on the Rohingya in Rakhine have forced hundreds of thousands to flee to neighboring countries. Sever Rohingya oppression took place in 2017 and 2018. More than one million Rohingya have migrated in Kutupalong-Balukhali, and Nayapara refugee camps, respectively, in Ukhia, and Teknaaf of Cox’s Bazar district of Bangladesh. This article deals with the origin of Rohingyas and their citizenship in the Rakhine State of Myanmar.

Knowledge is considered as the basis for developing sustained long-term competitive advantage for every organization. In the 21 st century every organization becomes knowledge based for the sustainable development. Knowledge sharing is an important instrument that turns individual knowledge into group organizational knowledge. It is one of the main knowledge processes in a present dynamic and competitive era for the development of organizations. The knowledge sharing practice plays a remarkable role in the development and innovation in many areas of organizations. In this paper an attempt has been taken to discuss techniques, barriers and benefits of knowledge sharing in organizations.Barriers are the hinder of flow of knowledge among employees in organizations. KS practices have not accomplished properly in many organizations due to possible KS barriers. Lack of trust is a significant barrier for KS in organizations. The influence of the organizational culture, lack of proper leadership, and lack of appropriate rewards in the organization are barriers of KS (Zawawi et al., 2011). Lack of communication, inequalities in status, lack of leadership and managerial direction, deficiency of sharing resources in organization, lack of formal and informal mechanisms and spaces to improve sharing activities, missing of sharing initiatives into the organization, deficiency of sharing resources, lack of proper space of KS, unwilling of sharing knowledge of highly skilled and experienced staff, and lack or an exiguity of network connections are barriers to organizational KS (Riege, 2005).Shortage of skilled personnel, finance, and information and communication technology are also barriers to KS in organizations. Most cases employees in organizations are reluctant to share knowledge among themselves because of lack of time and effort to KS, lack of motivation and credibility, fear of one's KS may lessen job security, poor evaluations by the receiving unit, differences in education levels, and lack of social network (Chiu et al.

This article tries to discuss profit maximization policies by using four variable inputs, such as capital, labor, principal raw materials, and other inputs in an industry, where mathematical economic models are applied by considering budget constraint. For the sustainable production, every industry should apply scientific method, such as mathematical techniques to obtain more accurate results. In the study Cobb-Douglas production function is analyzed with detail mathematical analysis. The sensitivity analysis is included in the operation to show profit maximization that is a pivotal goal of the industry. The economic predictions of future production are provided through the comparative statics to become sure of profit maximization before starting of production in the industry. In the study Lagrange multiplier technique is applied to achieve optimal result in every step of industrial operation.

A consumer is considered as a person or a group of people who uses purchased goods, products, or services only for personal use, and not for manufacturing or resale. Consumers usually purchase valuable and useful commodities or goods by spending all or partial of their income. The property of a commodity that enables it to satisfy human wants is called utility. Producers must be conscious to increase the utility among the consumers. This study has considered the maximization of utility problem of consumers of Bangladesh subject to two constraints; namely, budget constraint and coupon constraint. Consequently, in the study two Lagrange multipliers are used and interpreted these with mathematical analysis. Prediction of consumer behavior will help both producers and consumers to take decision of their future economic productions and consumptions, respectively. This article is ornamented with sufficient theorems and economic analyses. So that all the readers find interest when go through the economic analysis of utility maximization.
