본 연구는 질적 연구를 통하여 의료급여환자들의 의료이용 경험을 이해함으로써 의료급여환자와 건강보험환자 간 의료이용량의 통계적 차이현상의 원인과 과정을 파악하기 위해 수행되었다. 주요 분석결과는 다음과 같다. 첫째, 의료급여환자의 과잉의료는 대체로 존재하지 않으며, 복합적 질병을 가지고 있어서 발생하는 것이다. 그러나 물리치료와 한방 침에 있어서 일부 과잉이용이 발생하고 있는 것으로 판단된다. 둘째, 의료급여환자들은 의료비를 마련하기 위하여 생계급여에서 일부를 활용하거나 주변 가족이나 이웃의 도움을 받고 있었다. 그러나 과도한 의료비 부담으로 비급여 의료서비스와 대형병원 의료이용은 실제 의료필요만큼 이용하지 못하고 있었다. 또한 일부 환자는 아파도 우선 참고 견디고 있었다. 한편, 일부 의료기관에서는 의료급여환자에 대한 차별적 진료행위를 여전히 하고 있었다. 셋째, 공무원과 의료기관 모두는 의료급여환자에게 의료비 지원정책에 대한 미흡한 정보 제공 등 충분한 도움을 주지 못하고 있었다. 넷째, 정부가 수행하고 있는 의료급여정책인 선택병의원제도, 의료급여사례관리제도, 진료연장승인제도 모두는 불필요한 의료이용을 감소시키는데 기여하고 있는 것으로 판단된다. 그러나 의료급여환자들에게 필요한 의료이용을 제한하는 문제를 초래할 수 있어 이에 대한 대책마련이 요구되었다. 이상의 연구결과를 살펴보면 건강보험환자와 의료급여환자의 의료이용량의 차이를 통계적으로 검증한 선행연구와는 달리 의료급여환자들은 의도적인 과잉이용을 하지 않고 있으며, 오히려 필요한 의료서비스 이용에 제한을 받는다고 생각하고 있었으므로, 이에 대한 대책마련이 요구된다.

We propose an Agricultural Infrastructure Expansion Plan (AIEP) for North Korea following unification from the standpoint of a united Korea's social stability. We predict the food demand after unification, according to four different development scenarios based on the AIEP. These scenarios include meeting a self-sufficient level in the staple food crop, satisfying long-term food supply and demand for the North Korean people, achieving a level of North Korean food consumption comparable to that of South Korea, and maintaining productivity to stabilize of North Korea's rural society. We present the results of a 'benefit-cost' analysis in meeting the production targets of predicted food demands after unification from a civil engineering perspective. We found that the estimated total costs would range from 15.2 to 43.0 billion dollars depending on the particular AIEP scenario. In our analysis, all of the four scenarios presented above demonstrated a high degree of economic validity. We conclude that the AIEP is a necessary and economically valid project for a united Korea's future because it would forestall the collapse of North Korea's rural communities, thereby preventing tremendous economic losses upon unification.

The objective of this research was to estimate residents' willingness-to-pay using contingent valuation method and to investigate their environmental sensibilities prior to conduct the costbenefit analysis on the watershed management program of integrated sewerage construction and operation in the catchment of Dam Chung-Ju. A set of questionnaire was prepared and asked to 1,200 residents at downstream area as well as upstream area of Dam Chung-Ju. As a result, environmental sensibility of the residents living in the catchment of upstream of Lake Chung-Ju seemed very high. However, the substantial practice in their own life for conserving their environment was inactive, although residents' efforts trying to collect and dispose garbages in separate containers and to minimize the waste discharge load were actually made. The willingness-to-pay on each month for 20 years was estimated as 4,841 wons for the openended question and 3,411 wons for the close-ended question. Factorial analysis was also performed to obtain correlation among the questions asked. Seven groups of the correlated questions were identified and their contribution to the estimated willingness-to-pay was analyzed.

The controls of Information Systems (IS) have been an more critical issue controls as the sophistication and integration of IS is more proceeded. ITGI (The Information Technology Governance Institute) of ISACA (Information Systems Audit and Control Association) has suggested COBIT (Control Objectives for Information and related Technology) and this has been widely recognized the evaluation model of IS controls. In COBIT, IS was evaluated in terms of process, information quality, and IT resources. This study used COBIT in order to suggest and empirically test an evaluation model of IS service. The data was collated from one major Chinese SI (Systems Integration) company in four domains of processes : planning and organization, acquisition and implementation, delivery and support, and monitoring. Seven factors are extracted using an exploratory factor analysis as follows : Overall IT planning process, technological assessment process in IT planning of IT, cost-benefit assessment process in IT planning, implementation process, support process, monitoring process, post-implementation evaluation process. The results of confirmatory analysis of three alternative measurement models indicated that the measurement model with one inherent or conceptual variable has greater model fitness than the other models. This study suggests the logical and general way to test and apply COBIT in evaluating IS services.

This study suggests systematic procedures to improve safety policies on prevention of industrial accidents associated with industrial machines and devices. Specifically, new method of cause analysis of industrial accidents associated with industrial machines and devices is suggested and the related accident data are re-analyzed. Effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, safety device regulation and safety inspection of industrial machines and devices are also analyzed. Based on those analysis results, transition from the current user-oriented safety device regulation to more balanced direct regulations on both manufacturer and user is suggested. Together with severity and frequency of industrial accidents, unit severity and unit frequency need to be taken into account to further assess the risk associated with a particular industrial machine or device. Balance between safety regulations will be realized by proper adjustment of lists of safety certification and inspection, and certification and inspection standards. This will also guarantee the maximum benefit over cost in such safety regulations.

The choice of big public investment project needs an appropriate feasibility analysis before it is implemented, bemuse a rot wisely chosen one would bring about big and longrun societal costs. But the feasibility analysis for the big public investment project in Korea has been done without linking the economic benefits and environmental damages. Consequently social conflicts arose frequently during and after project implementation, owing to such concerns asincreasing costs and serious ecological damages. The recent social conflict over the Saemangeum Project is a typical case. This reclamation project began in 1991 and finished 60% of the whole process in 1999, when its feasibility was again assessed under the public pressure by the joint assessment team consisting of both citizen's and government's professionals. Even the assessment report by this joint team could not show the convincing results owing to the improper assessment procedure and failure to set proper feasibility criteria. This paper pointed out the limitations of our current procedure of feasibility assessment and identified the concrete problems that atosee during the recent reassessment process of the Saemangeum reclamation project by the joint team. In order to improve the current problem-ridden practices, it is concluded by the policy recommendation for establishing a right feasibility assessment procedure for the public investment projects.

The use of national R&D reports becomes a difficult task due to the different level of service being provided and the different way used for its construction by the institute in management. One-stop service of its contents is impossible and there is a lack of specialized service such as a system to satisfy the various needs of the researchers. This study analyzes the laws related to the national R&D reports and the evaluation system of the R&D outputs for the design and construction of the DB and system for the management of the national R&D reports. We also perform an analysis of the economic effect of the system.

As the chemical industry becomes more advanced, the awareness of chemical accidents is rising, and legal systems for chemical safety management are strengthened. In this study, quantitative risk assessment of liquid chlorine leak was conducted. Risk assessment was performed in the order of frequency analysis, consequence analysis, and risk calculation. The individual risk was presented in the form of contour lines. The social risk was expressed by the FN curve. The risk of day and night was in an unacceptable area, so it was required to mitigate risk. Therefore in-building, which could trap the pool, was selected as a risk mitigation measure. As a result of the cost benefit analysis, it was concluded that this measure should be reasonably implemented.

Until now, it has been for choosing most economic result to be generally used for designing remote MicroGrid (MG) system. It is able to make economic benefit by reducing operation cost, but proportion of renewable energy will be minimum. In other words, it is difficult to get an effect by renewable energy because economic feasibility is an only consideration. Therefore, various factors should be considered and design objectives should be are diversified to design proper remote MG system. In this paper, remote MG system is classified into two types according to design objectives, and they are analysed through case study based on economic evaluation. In addition, economic feasibility for each type is analysed through sensitivity analysis according to various factors that affect the design results of the system.

The Formal Safety Assessment (FSA) is a structured and systematic methodology developed by the IMO, aimed at assessing the risk of vessels and recommending the method to control intolerable risks, thereby enhancing maritime safety, including protection of life, health, the marine environment and property, by using risk analysis and cost-benefit assessment. While the FSA has mostly been applied to merchant vessels, it has rarely been applied to a DP vessel, which is one of the special purpose vessels in the offshore industry. Furthermore, most of the FSA has been conducted so far by using the Fault Tree Analysis tool, even though there are many other risk analysis tools. This study carried out the FSA for safe operation of DP vessels by using the Bayesian network, under which conditional probability was examined. This study determined the frequency and severity of DP LOP incidents reported to the IMCA from 2001 to 2010, and obtained the Risk Index by applying the Bayesian network. Then, the Risk Control Options (RCOs) were identified through an expert brainstorming and DP vessel simulations. This study recommends duplication of PRS, regardless of the DP class and PRS type and DP system specific training. Finally, this study verified that the Bayesian network and DP simulator can also serve as an effective tool for FSA implementation.
