Education Provision to Internally Displaced Children in Northern Shan and Kachin States in Burma

Thousands of people have been displaced from their villages and have remained in the internally displaced camps since the fighting resumed in Northern Shan and Kachin states in Myanmar (Burma) in 2011. Displaced families and children experience a number of challenges in the camps, one of which is access to education. This capstone explores the non-governmental organization professionals’ perspectives about the challenges they face with regards to providing quality education to displaced children in Burma through these research questions: 1) How do NGO professionals address the challenges they experience in the provision of education to internally displaced children in Burma? 2) How do NGO professionals ensure the provision of a quality education to internally displaced children in Burma? Drawing on a qualitative research methodology employing individual interviews and document analysis, the findings revealed four main challenges organizations experience in education provision to internally displaced children: access to internally displaced persons (IDPs); collecting comprehensive data of IDPs and displaced students; coordination with the national government; and funding for education for displaced children. These challenges are complicated by Myanmar’s internal politics, which further makes it difficult for international organizations to provide education to displaced children

Investigation of Fineness and Calcium-Oxide Content in Fly Ash from ASEAN Region on Properties and Durability of Cement–Fly Ash System

Fly ash is a ubiquitously used pozzolan in cementitious material. Its technical knowledge has been widely studied for several decades and seems very well-established. However, a practical challenge currently exists. Different fly ash, even in different batches produced from similar power plant, has a wide variation of properties. To better control the wide variation of properties, this study aims to assess the effects of cementitious mixtures containing different fly ash properties (degree of fineness and CaO content) on heat release, flow, compressive strength, chloride ion penetration resistance, and carbonation resistance. Results from statistical analysis of 270 tested data of fly ash in various ASEAN countries indicate that the fineness of fly ash particle influences on the compressive strength, chloride ion penetration resistance, and carbonation resistance. Whereas, the CaO content of fly ash only statistically impacts on the compressive strength, but not on the chloride ion penetration resistance and carbonation resistance. To reduce the current practical challenge of the wide variation of cement–fly ash composite properties, their durability properties can be improved by adding smaller fly ash particle in cement system. The control of fly ash production by delivering its optimal degree of fineness is more important than selecting the optimal CaO content of fly ash. The study offers a deep technical value differentiating between effects of its fineness and CaO content such that the fly ash producers and consumers can realize and offer the optimized fly ash for good product quality

Exploring ASEAN Fly Ash for Enhancing Cement Hydration and Service Life Prediction of Portland Cement Mortar

The durability of cementitious materials can be improved with the widespread utilization of fly ash (FA). Although FA has been available for use in cement and concrete industries for decades, there is still a practical barrier associated with its application. The difficulty stems from its wide variety and heterogeneity. The purpose of this research is to conduct both experimental and numerical investigations to achieve a better understanding of managing the variation of FA, which reflects its durability. The chemical properties and particle size distribution of FA from five distinct sources in ASEAN region were analyzed. In addition, the degree of reactivity, flow, toughened porosity, and apparent chloride diffusivity coefficients of blended FA-cement systems were studied (Da). The Life365 service life model was executed. Using analysis of variance (ANOVA) and sensitivity analysis using linear regression, the experimental outcomes were statistically examined. Having a 15% FA replacement level resulted in a roughly 70% decrease of the Da value, extending its serviceability by around 13%. The chemo-physical processes in multi-scale structures were shown to be the most important element by statistical analysis, and the degree of response in blended FA-cement systems and its toughened porosity were found to be among the most beneficial aspects affecting its durability

A Study of Eastern Culture from the Philosophical Perspective

In the world philosophies the Eastern has investigated everything in their aesthetic component on the other hand the Western has investigated these things in their theoretic component. The main objective of this paper is intended to study on Eastern culture from the philosophical Perspective. Most of the Easterners emphasized on man than on his natural world and one of the characteristics of Eastern culture is fundamentally religious in character. The research problem of this paper is “why the Easterners’ ways of thinking seems to emphasize on the human concern in aesthetic component?” The solution of this paper is that Easterner’s ways of thinking generally based on emotional sense than rational sense. Hence they place emphasis on knowledge by intuition and on contemplation of everything in their aesthetic immediacy. This research paper will contribute to promote understanding that people can put into practice reconciliation of the philosophical perspective of the East and the West in order to achieve a comprehensive integration. As a consequence we enable to establish mutual understanding and good communication among different cultures
