This study aims to feasibility study of the Youth Center. Welfare of adolescents is appeared to a matter of concern and interest as social problems of various kinds related adolescents including the fire at a beer bar in Inchon occur recently. In view of government, in addition to fairness of facility location, location of such facilities arc to be determined the respect to cost of locating facilities and developmental direction in the future. A feasibility study is and effective tool in determining the decision of investment or not and the level of investment priority on projects requiring a sizeable investment and the feasibility of a project. The first, it is to select reasonable location. It was selected three and two by consideration of facilities distribution and connection with others. Five proposal selected was estimated by five element of approach, demand, symbol, reality, environment. In result proposal I was chosen. The next, it is to estimate scales. It was estimated by analysis of catchment area, similar facilities, programs, in result 7,260㎡ come into analysis to the best gross area. The finally, it is to study on economical efficiency. Income Statement estimated was came out ₩1,7billion. in addition, it offer various benefit by public facilities.

2019년 정부는 경제성이 예비타당성조사 통과의 결정적 요소로 작용하는 문제 개선을 위해 종합평가의 경제성 항목 가중치 최대치를 50%에서 45%로 축소하도록 제도를 개선하였다. 이 연구는 2019년 제도개선에 따른 효과를 분석하기 위한 것으로 제도 개선 전과 후의 차이를 검증하였다. 회귀분석과 상관관계 분석결과 두 기간 모두 높은 상관성을 보였으며, Z검증을 통한 차이는 통계적으로 유의미하지 않은 것으로 분석되었다. 이 결과는 경제성의 영향력을 축소하기 위한 제도 개선이 효과가 없었다는 것을 의미한다. 따라서 종합평가 각 항목의 가중치를 기존 사업 등에 다양하게 대입해 재평가 해보는 등의 연구를 통해 보다 실효성 있는 종합평가 연구 설계 논의가 필요할 것으로 판단된다.

Among large developmental projects, those of the government and public institutions with the total budget of more than 50billion wons can be executed only when the feasibility of the project has been testified through the procedure of preliminary feasibility study. Multi-purpose dams are public structures that can supply water, produce electricity, and control flood, they belong to large national projects that require legal evaluation procedures such as preliminary feasibility study and environmental impact assessment(EIA). The index that should be considered to be important in dam plan is the migration of residents in submerged district. The importance in the preliminary feasibility study is 4.93 points(98.6 in the scale of 100 at maximum). Among the 12 assessment elements of the policy and economy in the preliminary feasibility study, the element of environment assessment is turned out to be 4.68 points in the assessment importance (93.5 in the scale of 100 at maximum), which is the second in the total ranking and the first in the field of policy, indicating that the element is very important in dam construction planning.

A marine ranching project in Tongyoung was established in 1998, lasting 9 years to 2006. Project activities included the deployment of artificial reefs, the release of young fishes like jacopever and rockfish, and input/output control for specific marine ranching areas in Tongyoung. This report focuses on the economic feasibility of the project in hindsight. Analysis concentrates on three aspects; (a) direct economic benefits, such as increasing effects of fisheries income and savings in harvesting costs, (b) indirect benefits, including increasing effects of recreational fishing and saving R&D costs, and (c) costs, including releasing and purchasing costs of artificial reef and juvenile fish, R&D costs, maintenance costs and harvesting costs. Results show that NPV=4.7 billion won, IRR=8.55% and B/C ratio=1.286 under Scenario 1, which considers the saving effects of R&D costs, and NPV=0.9 billion won, IRR=6.03% and B/C ratio=1.11 under Scenario 2, which does not consider the saving effects of R&D costs, based on 5.5% of the social rate of discount. According to sensitivity analysis, the economic feasibility is very sensitive to the recapture rate.

This study aims to estimate the optimal probability distribution of daily electricity generation by wind power, in order to contribute in rural green-village planning. Wind power generation is now being recognized as one of the most popular sources for renewable resources over the country. Although it is also being adapted to rural area for may reasons, it is important to estimate the magnitudes of power outputs with reliable statistical methodologies while applying historical daily wind data, for correct feasibility analysis. In this study, one of the well-known statistical methodology is employed to define the appropriate statistical distributions for monthly power outputs for specific rural areas. The results imply that the assumption of normal distributions for many cases may lead to incorrect decision-making and therefore lead to the unreliable feasibility analysis. Subjective methodology for testing goodness of fit for normal distributions on all the cases in this study, provides possibilities to consider the other various types of statistical distributions for more precise feasibility analysis.

The primary objective of this study is to develop a conceptual design of all-in-one attachment based steel pipe pile cutting robot that improves the conventional work in safety, quality, convenience and productivity. For this, the following research works are conducted sequentially; 1)literature review, 2)field investigation, 3)selection of element technology for conceptual design, 4)deduction of conceptual design and its work process, 5)technical feasibility analysis of the conceptual design and its work process. As a result, leveling laser and laser detector, plasma cutter, rotary grapple are selected as core technologies. Futhermore, a conceptual design and work process of an all-in-one attachment based steel pipe pile cutting robot are developed based on the core technologies. According to the technical feasibility analysis result, at least 76.8% of the respondents are selected positive answer about each device of the all-in-one attachment based steel pipe cutting robot. It is expected that the application range and impact on the construction industry will be enormous due to the increasing trend of the steel pipe pile market.

사회간접자본(SOC)은 국가 산업부문과 국민경제에 매우 큰 영향을 끼치는 생산요소로 이에 대한 투자는 경제성장에 있어 필수적이며, 국가 경쟁력을 결정하는 주요 요소이다. 이러한 중요성을 인식하여 정부에서는 지난 1999년부터 예비타당성조사 제도를 도입하여 SOC 사업시행 유 무를 검토하고 있으나 과학적 투자평가방법의 미비, 조사 결과의 신뢰성 저하 등 근본적인 문제가 끊임없이 제기되고 있다. 이를 개선하고자 수행된 주요기관의 선행연구는 대부분 수요추정 및 경제성 분석 중심으로 진행되었고, 예비타당성조사의 주요 단계인 정책적 분석에 대한 연구진행은 아직 미흡한 실정이다. 이에 본 논문에서는 관련 학문과의 적절한 융합과 조화가 요구되는 (예비)타당성조사의 정책적 분석단계에 대하여 현행 전문가의 경험과 관련 자료에 의한 정성적 평가를 개선하고자 가치공학(VE)의 성능평가기법을 활용한 정량적 의사결정모델을 개발 제안하여 분석결과의 정량화를 유도하고 체계적 분석절차에 의한 전략적 판단도구로의 활용과 신규투자사업 목표에 대한 정책적 측면의 가치향상에 기여하고자 한다.

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.

On the contrary to the expansion of feasibility studies on public construction and development projects, there is few feasibility studies on S&T, especially large-scale basic research facilities. Based on this critical mind, we tried the first feasibility study on large-scale basic research facilities, that is, the 4th Generation Light Source. First, it is validated whether the construction of 4th Generation Light Source is economically feasible and second, if economically feasible, the optimal place and time for construction are analyzed by using Analytical Hierarchy Process. This research shows that the construction is economically feasible irregardless of scenarios on future bio-medicine industry growth and to construct at Pohang in 2006 is optimal strategy. On the basis of this analysis, the feasibility studies on large-scale basic research facilities are expected to be more expanded and developed.
