본 논문은 공공부문에서 정보화사업의 타당성 검토 방법론을 비교분석하고 문제점을 도출하여 문제점 극복방안을 제시한다. 기존의 방법론이 재무적 성과에 중점을 두고 있는 반면에 가치 중심의 평가를 제안하고 특히 EA 기반의 타당성 검토방법이 더욱 합리적이고 포괄적인 방법임을 제시한다.

Feasibility study on large scale projects like an investment on infrastructure development is very important because it provides fundamental data which determine the total investment size and duration. However, previous feasibility studies have a few problems of ambiguous estimation standards, unsystematical estimation methods, and so on. Accordingly, this study intends to regulate tile problems on economic feasibility as well as financial feasibility study which have been considered more critical in recent time, subsequently presents a reform measure. Also, this study identifies predictable risks during the feasibility study, presents a scheme which lets investor and owner control the risk themselves through a process which uses theoretical and political management plans.

폐기물과 오염물질 투기로 인해 발생된 오염지의 복원은 1980년대 초반 미국이 본격적으로 시도하여 현장조사, 위해도 평가, 타당성 검토의 3단계를 거쳐 복원대책을 수립하는 정형이 이루어졌다. 이 정형에서는 먼저 현장조사로 오염상태에 대한 자료를 수집하고 위해도 평가로 오염도가 인체와 환경에 미치는 위해도를 정량화하며 타당성 검토에서 위해도를 제거하기 위한 각종대안을 검토하여 최종안을 선정한다. 이 과정 자체는 합리적이었으나 여러 가지 시행착오를 거치며 과잉대책이 남발되고 사업효과도 미흡하여 점차 예산낭비의 대표적인 사례로 비판이 제기되었다. 시행착오의 가장 큰 기술적 원인은 위해도 평가와 별개로 타당성 검토를 수행하며 비현실적인 완벽복원을 추구한 탓이며 이를 극복하려는 최적화 기법이 90년대 초반에 소개되었다. 이 최적화기법은 타당성 검토단계에서 각 대안의 잔류 위해도를 산정하고 해당대안의 비용과 비교하여 위해도를 허용수준으로 줄이는 최소비용 대안을 발견하는 방법이다. 이 최적화기법을 실제 프로젝트에 적용한 결과 복원대책 수행에 기대 이상의 비용절감을 이루고 정부의 수용도도 높았다. 특히 정비대책에 현장조건의 특성을 활용하는 창의적 대안을 도입하면 효과를 극대화 할 수 있는 바 두 가지 사례를 소개하였다. 앞으로 상당한 투자가 예상되는 폐광오염 문제에도 이 기법을 적용하면 비용과 효과를 최적화할 수 있을 것으로 기대되어 그 모델을 제시하였다.

Recently our country need to change about hospital building operation and business change.The recent real estate development projects are made in very complex due to the diversity of development method or its legal aspects. Under such a real estate investment, the review of investment yield rate is fundamentally important for the one that invests and the one that finances it. Previously, the focus was in the review of the time to turn the surplus or the plan for making repayment of the borrowings, and without the analysis of sufficient investment yield rate. For a simple issue of finding the most advantageous project method, there is a need for reviewing the taxation issues, fund procurement method, legal aspects, policy analysis aspects and others. Therefore, the real estate investment is now likely to encounter the form of having the time of venture as well. In conclusion, the scientific and reasonable decision making in investing on the real estate does not suggest the absolute evaluation standard but the need and the use are more and more demanded.

Environmental impact is getting more attention in many feasibility studies for railroad-related projects and research items. For sustainable growth and green transportation, the benefits typically used for feasibility studies in railway-related projects, are composed mostly of economic criterions which is not considering growing attention on changing paradigm. Based on the analysis of current methodologies, improvements in estimating environmental impact especially on noise and pollution are suggested. Active steering bogie has been proposed to satisfy stabilizing and steering performance of railroad. This paper describes the feasibility study of the active steering bogie for a urban railway vehicle based on environment-related criteria.

The development project usually aims to get a certain amount of return for its investment in land and capital. The success of such project is dependent on the accurate analysis of the feasibility and for casting. It is, however, very difficult to predict due to various environmental factors. For this, it is necessary to constitute a systematic and objective method of analysis. However, there is no method of analysis for numerous qualitative factors, such as legal, environmental, marketability. Moreover, conventional methods have some limitations because they are processed without all the scope of analysis items and any evaluation criteria. Therefore, this study will provide computerization model for feasibility study focusing on the apartment development project by a pre-sall method. This research does casestudies to assess the feasibility analysis by the computerization model and compares to the results of the conventional methods. It showed that the evaluation results for the qualitative analysis were proportional to actual sale result. This implies that qualitative subjective factors have high correlation with sale rate and sale prices.

Preliminary feasibility study(PFS) was introduced in 1999 by financial authority to encourage a cautious approach to new large-scale public investment project. As it applied cost-benefit analysis as prime measure for decision-making, various issues have been arisen concerning feasibility analysis on R&D programs. This work is intended to suggest standard approaches to be established in PFS on R&D program as follows: 1. The issue questions can be induced in a standard way by 15 representative questions and their correlation with evaluation criteria. 2. The analyzing strategy can be standardized by establishing standards for classification of R&D effects and R&D logic analysis.

The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.
