To improve access to the learning opportunities of students with disabilities, this study is to identify the potential of the information communication technology in education for the disabilities and to suggest the policy reforms for the special education technology. To answer it, the related literatures of other developed countries and Korea were collected and analyzed by desirability and feasibility as criteria. From the view of the desirability, this study found that the policies of special education in Korea were still regarded as subsidiary and separated from the general students. Moreover, from the view of the feasibility, the law and financial support was relatively insufficient than other countries to implement the policy more effectively and stably. To solve these problems, this study suggests the policy reforms in Korea as five areas and seven tasks.

Objective: The purpose of this study is to survey trend and the real state of ageing population in UK, and its charge organizations, relevant policies and studies. Background: As in other countries, UK population is ageing and people aged 65 or over account for about 17% of population in UK. Considering this ageing population, there are varying basic studies and policies for older people in UK. Method: First, the author consulted ageing and its policies in UK with some faculties in an UK university. Next, based on the results of consultation, wide literature survey was conducted, which includes papers in relevant academic journals, publications and website surfing. Results: A number of basic studies for surveying status and characteristics of older people as well as simple population trend for them have been conducted in UK. Healthcare services are free for all UK residents, and varying social care services including equipment, home and residential cares, financial support, etc., are provided by local governments. Cost of social cares is means-tested and is not free for everyone. There are a number of governmental or non-profit organizations dedicated to help older people access social care services or to financially fund research projects older people. Conclusion: There are more basic studies, and healthcare and social care services for older people in UK, compared to Korea.

Background & objective: The Korean government has expanded its benefit coverage to enhance patients' access to orphan drugs and cancer medicines. However, the number of new drugs whose indications were not applied to reimbursement in health insurance was increased. This study aimed to understand the perspectives of experts and various stakeholders on the introduction of a new funding program for cancer treatment and orphan drugs. Methods: We conducted email surveys comprising 19 questions, from September 9 to 26, 2016. We distributed questionnaires to members of the Pharmaceutical Benefit Appraisal Committee and Cancer Assessment Committee. We also conducted a qualitative study through group interviews with stakeholders, including pharmaceutical companies and some patient groups for diseases. Results: A total of 35 survey respondents recommended the introduction of a funding program for orphan drugs, whereas 66% recommended the launch of funding for anticancer drugs. In addition, most pharmaceutical companies and patient groups recommended the introduction of new funding programs targeting patients with cancer and rare diseases. However, some participants asserted that it would be more appropriate to modify the existing reimbursement scheme than launch new funding. Conclusion: This study concluded that introducing new funding needs a social consensus to relieve financial hardships at the patient level.

This study aims to contribute to urban policy for more effective disaster prevention, as abnormal natural disasters are becoming more frequent. Up to now, the urban plan for disaster prevention in Korea merely includes basic principles and necessities of measures as an early stage. Furthermore, there are difficulties to make specific programs because the legal system, technical instruments, and financial supports are not sufficient. Therefore, this study figures out problems in the current plan related to urban prevention after analyzing the legal system and practices. Resulting from case studies in developed countries, the study draws significant implications, as follows: enhancing legally binding force; improving the procedures for the programs; establising technical infrastructure. It first suggests a way for the urban policy for disaster prevention by considering our local features comprehensively. It then defines the roles of central, local governemnts and research institutions, and the procedure for urban disaster prevention planning building on the individual roles. This study concludes that an emphasis should be placed on institutional tools necessary to publish technical guideline and establish the system so that urban planners more easily access to disaster risk information.

The study empirically examines the effects of loan portfolio diversification on bank risk and return in the nascent banking market of Vietnam. Loan portfolio diversification is captured through the Hirschman-Herfindahl index and the Shannon Entropy with sectoral exposures. We access each bank's financial reports to collect the required data, especially the breakdown of sectoral loan portfolios, thus constituting a unique dataset. To compute bank return, we use the traditional accounting indicators, including return-on-assets, return-on-equity, and net-interest margin. For bank risk, we utilize the loan-loss provisions and non-performing loans relative to gross customer loans. Using a sample of 30 commercial banks over the period from 2008 to 2019 and the system generalized method of moments estimator for the dynamic panel, we indicate the downsides of portfolio diversification. Concretely, we observe that all diversification measures exhibit significantly negative signs in all regressions across different bank return proxies. At the same time, the estimates display the significant and positive impact of diversification on the non-performing loan ratio. Hence, sectoral loan portfolio diversification significantly hampers bank performance in both aspects of lower return and higher credit risk. The results are robust across a rich set of bank performance and portfolio diversification measures.

In this paper, we describe a case study to improve performance through the load testing of multi-tired system for financial accounts before the system opening. The load test was conducted after the data collection tools(Performance Monitor, DB PSSDiag) were installed. By analyzing the collected log, we were able to identify the main sector requiring performance improvements among the presentation tier, web tier, business logic tier and data tier. The ASP.NET server-down on the web tier could be improved by modifying the parameter values in the configuration file. Some server downs occurred on the business logic tier when a large number of users access at the same time, were more difficult to be solved. By analyzing the hang-dump at the server-down time, we were able to find a process that caused the problem. and we had to modify the relevant codes. For major performance improvements of the data-tier, indices of some queries was optimized by using the built-in DBMS query analyzer, after analyzing the log of long-response-time queries. The problems and solutions considered in this case study will be a reference for the performance improvement of a multi-layer system with the similar structure.

This paper examines the factors that drive temporal income diversification in rural areas of the Mekong River Delta in Vietnam, based on a framework that conceptualized diversification as a function of a household's capacity to diversify and incentives (both push and pull factors) to diversify. Drawing from five rounds of the Vietnam Living Standard Measurement Surveys covering a 13-year span (1993-2006), two panel datasets made from five cross-sectional samples are used for the analyses. The data are drawn from the Vietnam General Statistics Office. Both tobit model and Ordinary Least Squares model with random and fixed effects are applied. The main points emerging from the analysis is that income diversification is strongly influenced by household labor capacity. The relationship between household labor capacity and increasing insertion in non-farming wage activities is not driven by unobserved time-invariant factors such as household ability and motivation, but is instead driven by the higher labor capacity of households. In terms of the other household capacity variables, the effect of farm size is much larger in terms of retaining households in traditional occupations as compared to pushing them towards non-farm wage employment. Other variables such as household access to financial capital do not play an important role.

Livelihood capitals have a clear influence on livelihood development. As for the livelihood results, it has been pointed out in the analysis of the poor households that the ability of people to escape poverty depends especially on the access to livelihood capitals. This study aims to analyze the impacts of livelihood capital on poverty among mountain people who depend on forests through human capital, social capital, natural capital, physical capital and financial capital. This research employs the model of binary regression function. Independent variables x1, x2, …, xn are targets of livelihood strategy, vulnerability context, and livelihood capitals. These variables were selected to be included in the original model with dependent variable Y as poor and non-poor households. This study surveys households living in upland areas, near forests, and households of ethnic minorities. The results show that,out of the poor household rate, nearly 4% are newly-poor households or those falling back into poverty. Therefore, the government needs to pay more attention to this disadvantaged group and implements policies such as education and training policies, credit support policies, policies to support forest development, and payment for forest environmental services in the context of emerging countries like Vietnam.
