본 연구에서 부산대표도서관 건립 기본계획 연구의 일부로 수행된 건립타당성 분석 중 경제적 타당성 분석에 대한 기초적인 작업을 수행하였다. 이를 위해 비용편익 분석과 순현재가치, 내부수익률의 방법을 활용하였다. 조건부가상가치법(CVM)을 활용하여 편익분석을 실시하였으며 부산대표도서관 건립부지를 중심지 또는 외곽지로 할 때의 값을 조사하여 비교분석하였다. 분석 결과, 중심지에 건립할 경우 부산대표도서관은 충분한 경제적 타당성을 갖는 것으로 나타났으며 외곽지에 건립할 경우 그렇지 않음을 확인하였다.

The most concerning issue of these days is the energy crisis caused by increasing threat of dependence on imported oil and volatile market trend. Under these circumstances, the PHEV(plug-in hybrid electric vehicle) is drawing attention for the next generation's car which could give a chance to decrease the dependence on imported oil and reduce the environmental impact of vehicle. The fueling cost of PHEV, one of the core factor of decision about buying car, should be calculated in the circumstances of Korea to make sure that PHEV has competitive power in real market. The fuel cost saving of PHEV versus CV(conventional vehicle) is simulated and discussed in the condition of increasing gasoline cost, electricity rate, and city-gas rate. In conclusion, the PHEV60-FS shows the best economic feasibility when gasoline price goes up. The PHEV20 has the most stable economic feasibility as electricity rate increases. The fuel cell cogeneration system for RPG could be an alternative for charger of PHEV in the near future.

예비타당성조사는 대규모 신규 공공투자사업에 대한 신중한 접근을 진작하고자 1999년에 도입되었다. 사업 타당성에 대한 결론 도출 시 비용편익분석으로 대변되는 경제적 타당성 분석을 중요시하므로, R&D사업의 분석과 결론 도출에 있어서 다양한 쟁점이 제기되어 왔다. 본 연구에서는 연구개발부문 예비타당성조사에서 표준화하여 적용할 수 있는 사항을 살펴보았으며, 대표질문과 평가항목 간의 상관관계를 통하여 쟁점 도출을 표준화하는 방안을 제시하였다. 그리고 R&D효과 분류와 논리분석의 적용을 통해 분석전략을 표준화하여 R&D투자 의사결정의 합리화에 기여하고자 한다.

The purpose of this study was to set and analyze the feasibility and survey of the Hanok(The traditional Korean style house) housing complex project within Seoul metropolitan area. The results of this study were as follows. First of all, a survey was carried out to find out the optimum Hanok style. The survey showed that many people chose a frond and back yard garden as a merit of Hanok and pointed out the weak crime prevention as a weakness of Hanok. The optimum size for a Hanok was from $264m^2$ to $330m^2$ and living space was from $100m^2$ to $132m^2$. And people considered about 120% of what the apartment sells for as the reasonable price of a Hanok. Based on the survey, this study planned a Hanok housing complex on a lot that has competitive price and analysed the feasibility of the housing plan. The result was that Hanok's construction cost per $3.3m^2$ to be a marketable product has to be below about 6 million Won. As a result, the construction cost-saving through the advanced technology and planning to meet the changing customers' needs are needed to vitalize Hanok's supply.

The purpose of this study is to provide the feasibility of apartment remodeling types in DaeJeon City. This study was conducted by survey for the residents' perceptions of the apartment remodeling. In addition, this study estimated the cost according to remodeling types by comparing it with that other apartments in DaeJeon City. By doing so, this study evaluated the feasibility of remodeling. The results of this study are as follows: 1. Not only the level of the residents' perception but also the intention of apartment remodeling was high. 2. The cost of remodeling was similar to that of residents had answered at questionaire. Thus, the remodeling cost proven to be very reasonable. 3. The cost of horizontally expanding remodeling type was cheaper than that of moving within the same apartment complex or into the new apartment. The cost of others (duplex, expansion or reduction of household) are cheaper that of moving. But one of the difficulties in carrying out these types lies in the fact that the remodeling should be performed in the apartment complex or building. Accordingly, this study proposes that horizontally expanding remodeling type is more feasible in DaeJeon City.

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.

Korea classified into a development country when UNFCCC was concluded in 1995. So Korea doesn't have a GHG reduction duty until 2012. As the UNFCCC is strengthened, recently there is a growing interest in renewable energy and energy usage efficiency improvement for reducing GHG emission. It is associated with CES and renewable energy. CES is a total energy (heat, cooling and power)supplier in aggregated demand zone like a hotel, building, hospital and redevelopment district using CHP and it improves energy usage efficiency. At present, renewable energy is needed for GHG reduction duty but renewable energy doesn't have economic feasibility. So renewable energy is needed various support system to popularize which is a FIT and RPS. Especially RPS is carrying out instead of FIT in many advanced country and it will be inroduced in Korea. RPS is a duty which electricity service provider must guarantee renewable energy as much as specific ratio of total capacity. Therefore this study conducts an economic feasibility estimation of CES considering renewable energy when RPS will introduced in the future.

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.

아파트 재건축사업은 신축사업과 달리 재건축조합의 설립 등, 사업시행의 절차가 복잡하고, 개발사업의 타당성을 조사할 능력이 없는 비전문가들로 구성된 조합이 사업주체가 되어 자율적으로 추진하는 민간사업으로 재건축사업의 타당성을 분석하고 검증하는 객관적인 절차가 없는 상태에서 설계사, 시공사 등 많은 주체들이 참여함에 따라 각 주체별 이해관계가 복잡하게 얽혀있고 오해와 불신 비리와 분쟁 등 주민마찰의 온상이 되어왔다. 본 연구는 아파트 재건축사업 타당성조사 분석모델 개발을 위한 기초적인 연구로서 아파트 재건축사업의 특성을 분석하여 타당성분석절차와 각 수익 비용항목에 대한 산정기준을 제시하였다.
