The endowment and concession has been put to practical use for the relocation projects of military Facilities. Yet, in terms of the project implementation, delay of a great deal of the projects is occurring due to related regulations and standards, as well as a lack of mutual understanding between project implementers and military units. This study analyzes the risk factors by identifying and prioritizing the potential risk factors at each stage of project implementation such as the issues that limit project characteristics and implementation. Among the derived risk factors, request exceeding facility standards in the licensing and design phases, opposition to troop relocation in the project approval phase, design change during construction phase in the construction and completion phases, dissenting opinions on endowed/conceded property in the property disposal phase and absence of facility standards in the MOA conclusion phase were found to be the main object of consideration in risk management. This study is expected to provide project managers with a guideline for effectively pursuing the projects, as it provides prioritization and optimization of risk management.

As gas hydrate is recently emerging as a new energy source to solve environmental and exhaustion problems caused by fossil energy, Korea is working on a gas hydrate development project under a 10-year plan from 2005 to 2014. Gas hydrate is expected to have a big effect on the economy and society of Korea, which is largely depending on energy imports besides water energy and atomic energy. However, it is uncertain whether the project will produce successful results. Thus, it is very important to improve its validity and to propose effective execution strategies by evaluating the value of the project in advance. Thus, this study intended to include new information, which had not been evaluated in existing methods, and to reduce biases or errors in value evaluation results by applying a fuzzy risk analysis to the real option model in order to evaluate the value of a gas hydrate development project. It is advantageous that the real option model based on the fuzzy risk analysis modelizes the vagueness and inexactness of intangible element judgment into an appropriate language scale so as to evaluate these elements clearly and integrate them with estimated financial performance results. The application of the fuzzy risk analysis makes it possible to conduct an analysis by dissolving a decision-making issue with complicated and various attributes into several simplified problems. With the continuing high oil prices and today's demand of clean energy, the necessity of energy resources and technology development projects keeps growing. Amid this situation, it is expected that these study results will contribute to proposing a guideline not only for gas hydrate projects but also for policy decision-making related to future energy industries.

The purpose of this study is to maximize project efficiencies in construction management by analyzing hierarchical factors that effect in project supervision system, and consequently constructing managerial CSF(Critical Success Factors). For this study, the tools for evaluating operating and management abilities of site engineers are built from analyzing status and issues, deducing influence factors and rating cardinal scales of these factors from survey results. These evaluation tools are reflected to the construction supervision decision making process so that can improve project management effectiveness.

전력산업 구조개편 이후 여러 가지 형태의 새로운 전력시장 참여자가 나타났다. 지역 에너지 사업(CES : Community Energy Service) 사업도 이러한 새로운 시장참여자의 하나로 소비자에게 전기뿐만 아니라 열과 냉, 난방 서비스를 동시에 제공하는 역할을 수행한다. 대부분 분산전원 기술을 이용하는 지역 에너지 사업은 기존 발전 사업자들이 경험하는 환경문제나 대규모 투자에 따른 위험을 피할 수 있는 새로운 전력사업 형태로 각광받고 있다. 또한 송전망의 부담을 주지 않고 소비지에 인접하여 전력을 공급할 수 있기 때문에 송전망 투자도 절감할 수 있는 장점을 보인다. 본 연구는 지역 에너지 사업의 편익을 알아보기 위하여 부하 모델링을 통하여 지역 에너지 사업의 운영 경제성을 평가하였다. 특히 연료인 천연가스 요금과 전기부하의 변화에 따른 경제성 변화를 평가하여 민감도를 분석하였다.

우리나라에서는 이제까지 치수사업의 타당성 분석시 경제성 분석에 너무 치우쳐 사업에 대한 의사결정과정이 단편적으로 진행되어 왔다. 이러한 문제를 개선하고자, 본 연구는 AHP(Analytic Hierarchy Process)과 효용함수(utility function)를 이용하여 대안의 수립, 평가, 선정, 우선순위 결정에 이르는 치수사업 의사결정과정을 모형화 하였다. 모형의 적용결과, 최선대안의 선정시 경제성 기준이 여전히 큰 비중을 차지하고 있었으나 단위 사업안의 투자우선순위 결정에는 위험성, 지속가능성 기준의 영향도 상당부분 있었다. 그러나 대안들 간에 변별력을 높이기 위해서는 경제성 이외 기준들의 속성에서 공간적 정밀도를 높이는 추가연구는 필요한 것으로 판단되었다. 본 연구는 치수사업 계획이 유역 내 단위사업안들로 조합된 대안들의 평가를 통해 이루어져야 한다는 점을 보여주고 있으며, 향후 점차로 유역단위의 치수계획이 정립됨에 따라 본 연구를 바탕으로 보다 구체적인 연구가 수행되리라 기대된다.

Purpose: In this study, potential demographic, social, and economic factors causing tuberculosis were identified, and eight cities in South Chungcheong Province were compared and analyzed with the IPA method. Method: The factors potentially affecting the prevalence of tuberculosis were categorized demographically, socially, and economically, and selected through brainstorming. Furthermore, potential factors affecting tuberculosis were derived using the revised IPA. Based on this analysis, areas with a potential risk of tuberculosis were classified, and the following policy implications were suggested. Result: The analysis found the three cities of Nonsan, Boryeong, and Gongju to have the highest potential risk of tuberculosis, and the frequency of potential risk factors in the above three cities to be 6 or more. Thus, an urgent policy response to prevent tuberculosis in these regions is required. Conclusion: According to the results of this study, it is necessary to take potential risk factors into account when promoting tuberculosis prevention policies and projects in South Chungcheong Province.

This research presents a methodology to define and apply appropriate index that can measure the risk of regional flood damage. Pressure-State-Response structure has been used to develop the Flood Risk Index(FRI), which allows for a comparative analysis of flood risk assessment between different sub-basins. FRI is a rational assessment method available to improve disaster preparedness and the prevention of losses. The pressure and state index for flood at 117 sub-basins from the year 1980s until the t 10s showed proportional relations, but state index did not decrease even though response index increased. This shows that pressures for flood damage relatively exceed countermeasure for flood. Thus this means we need to strengthen design criteria for flood countermeasure in the future. The FRI is gradually going down in consequence of continuous flood control projects. Flood risk of Han River and Nakdong River area is relatively lower than that of Geum, Seumjin, and Youngsan River area.
