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.

When infeasible interior-point methods are applied to large-scale linear programming problems, they become unstable and cannot solve the problems if convergence rates of primal feasibility, dual feasibility and duality gap are not well-balanced. We can balance convergence rates of primal feasibility, dual feasibility and duality gap by introducing control parameters. As a result, the stability and the efficiency of infeasible interior-point methods can be improved.

본 연구에서는 타 신재생에너지에 비해 영구적으로 사용이 가능하며, 예측가능한 대용량의 균질 에너지 생산이 가능하며, 발전효율이 높은 조력에너지를 활용하기 위한 조력발전 개발사업에 대한 경제적 타당성을 분석한다. 이를 위해, 세계적으로 청정에너지 프로젝트의 경제성 및 민감도 분석을 위해 널리 활용되고 있는 캐나다 천연자원부 산하의 CANMET 에너지기술센터에서 개발한 RETScreen을 활용하였다. 분석 대상 조력발전 개발사업과 관련된 자료가 총괄적으로 존재한다는 한계점에도 불구하고, RETScreen의 기능을 이용함으로써 기획단계에서 사업의 경제적 타당성을 검토하기에 충분한 예측력을 가진 분석 결과를 도출할 수 있었다. 경제성 및 민감도 분석 결과, 사업과 직접적으로 관련된 현금의 흐름만을 고려할 경우, 국내에서도 조력발전 개발사업은 충분한 경제성을 갖고 있으며 탄소배출권 시세와 전력 판매단가의 상승폭에 따라 조력발전 사업의 경제성은 더욱 높아질 수 있을 것으로 예측되었다. 본 연구의 결과를 바탕으로, 자연환경을 파괴하지 않는다는 전제 아래 조력발전소의 건설이 활성화된다면, 가까운 미래에 닥쳐올 에너지 문제를 슬기롭게 해결할 수 있을 것으로 기대된다.

건축개발사업은 목적물을 완성시킴으로써 이윤을 창출하는 사업이고, 프로젝트의 성공을 좌우하는 것은 프로젝트 초기에 사업타당성을 정확히 분석하고 예측하는 것에 달려있다. 사업타당성 분실은 본질적으로 현재시점에서 미래예측이라는 불확실성을 내포하고 있으므로 불확실한 상황 하에서 의사결정을 할 수밖에 없다. 이러한 불확실성 하에서의 의사결정방법은 통계학의 확률이론에 기초하고 있지만, 지금까지 사업 타당성 분석은 확률론적 결정방법에 의한 타당성 분석이 아니라 결정론적 방법에 의한 타당성분석을 적용하여 왔다. 따라서 본 연구에서는 초기 사업 타당성 분석 시 프로젝트의 성공을 위해 확률론적 방법에 의한 의사결정을 함으로써, 의사결정 자에게 좀 더 정확하고 신뢰성 있는 자료를 제공할 수 있는 시뮬레이션을 이용한 확률론적 분석방법을 제시한다. 본 연구 결과 확률론적 시뮬레이션 기 법은 건축개발사업의 재무적 타당성 분석 기법으로 적합하다. 중요한 사업 또는 신중한 의사결정시 이 방법을 활용함으로서 정확성과 신뢰성에 근거하여 효율적인 판단이 가능해 질 것이므로 그 활용성이 기대된다.

This study sought to contribute to the revitalization of local economy by developing a natural recreation forest, which is the base of ecotourism recreation, through utilizing forest resources and the natural environment of Gwangju-si. The study conducted a feasibility assessment through on-site surveys such as the suitability of the candidate sites, location analysis, and possibility of damage to the forest, before developing recreation forest sites in Gwangju-si and, based on the result, selected appropriate subject sites. The candidates for this study were 5 forest sites such as one site in the Mokheon-dong area, two in the Docheok-myeon area, and one in the Toechon-myeon area. For this study, the current status of the natural recreation forest was surveyed, its feasibility index and assessment process were investigated, and the local status and related regulations of Gyeonggi-do and Gwangju-si were reviewed. The final subject sites were selected after feasibility assessment utilizing assessment index in order to evaluate the candidate sites. The feasibility assessment was conducted after three separate on-site surveys for each candidate site between October 2018 and January 2019 utilizing "The Feasibility Assessment Criteria for Natural Recreation Forest (Notification 2018-71)" of the Korean Forest Service. The items instrumental to the feasibility assessment were classified into landscape, location, water system, induction of recreation, and development condition; the assessment was made after redefining each item into detailed items. Through this process, the Usan-ri area was selected as the final site for developing natural recreation forest, having obtained more than 100 points according to "The Feasibility Assessment Criteria for Natural Recreation Forest" of the Korean Forest Service. In order to develop natural recreation forest in the Usan-ri area in the future, further discussion is necessary with the relevant departments in consideration of the degree of ecological zoning map.

Purpose: The planning of medical facilities involves formulating a comprehensive medical basic plan, translating it into spatial dimensions through a space program. Feasibility assessment often relies on empirical methods like floor area per bed. However, with the shift towards specialized medical concepts, proportional scaling to bed numbers is challenging. This study proposes scale planning improvements during the feasibility assessment stage for comprehensive hospitals, analyzing cases using area determination factors and standard areas based on medical resources. Methods: The Korean Development Institute's Public Investment Management Center (KDI) identified issues in the scale determination of medical facilities in the Preliminary Feasibility Study Guidelines and investigated alternative approaches for determining the scale of a case that passed the preliminary feasibility study in 2019. The study assessed the feasibility of applying individual factors to determine not only the number of beds but also the scale at the sector and department levels. Additionally, a statistical analysis was conducted to examine the correlation between the total number of beds and various area determination factors. Results: Results suggest a strong correlation between total beds and major equipment needs, but in hospitals with <500 beds, this correlation weakens. Ward section scale is better calculated per ward type, not just total beds. Outpatient department scale depends on specialists, influencing treatment room numbers. Medical personnel play a crucial role in determining the scale of sections like rehabilitation therapy rooms, operating rooms, dialysis rooms, and overall facility scale.

This paper introduces a feasibility evaluation method for prognosis systems based on an empirical model in nuclear power plants. By exploiting the dynamical signature characterized by abnormal phenomena, the prognosis technique can be applied to detect the plant abnormal states prior to an unexpected plant trip. Early $operator^{\circ}{\emptyset}s$ awareness can extend available time for operation action; therefore, unexpected plant trip and time-consuming maintenance can be reduced. For the practical application in nuclear power plant, it is important not only to enhance the advantages of prognosis systems, but also to quantify the negative impact in prognosis, e.g., uncertainty. In order to apply these prognosis systems to real nuclear power plants, it is necessary to conduct a feasibility evaluation; the evaluation consists of 4 steps (: the development of an evaluation method, the development of selection criteria for the abnormal state, acquisition and signal processing, and an evaluation experiment). In this paper, we introduce the feasibility evaluation method and propose further study points for applying prognosis systems from KHNP's experiences in testing some prognosis technologies available in the market.

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.
