The urban center of a large city has a high concentration ratio of population, commerce, and traffic. Therefore, the expected effect is high from the introduction of the urban utility tunnel and it also has sufficient economic feasibility considering life cycle cost. Moreover, the construction cost can be greatly reduced if it is included in a large underground development such as a subway or a complex transfer center construction. However, it is not reflected in actual underground development plan. When planning a urban utility tunnel in Korea, it is expected to have difficulties such as the cost of relocation of the existing Life-Line, conflicts among the individual facility institutions, procurement of construction resources and sharing. Furthermore, it is possible to promote the project only if a consensus is drawn up by a collective council composed of all facilities and project developers. Therefore, an optimal alternative should be proposed using economic analysis and feasibility assessment system. In this study, the analytic hierarchy process (AHP) is performed considering the characteristics of urban areas and the importance of each indicator is quantified. As a result, we can support reasonable design capacity optimization using the feasibility assessment system.

Recently, remodeling has been introduced in the domestic construction industry as an alternative new construction. Its economic evaluation is the essential part of remodeling business. Therefore, this study has the purpose of presenting the method that is able to evaluate the actual value in the market. And this method can compare before & after value of remodeling in feasibility study. For this, this study reviews economic evaluation methods in construction and real estate fields and analysis their problem and merits & faults. With those facts, this study makes a mixed economic evaluation method that can be used in construction and real estate fields.

본 논문에서는 공공기관이 자체적으로 보유하고 있는 특허기술의 이전 및 사업화를 활성화하기 위하여 개발된 선별평가모델에 대한 타당성을 검토하고 공공기관이 보유하고 있는 1,166개의 특허기술을 공공기관과 평가전문기관이 각각 평가하여, 공공기관의 자체평가결과와 전문평가기관의 선별평가결과를 비교함으로써 공공기관의 자체평가능력을 제고하기 위한 방안을 수립한다. 선별평가점수와 자체평가점수의 차이를 분석한 결과 상용화가능성 항목은 차이의 평균(0.092)은 작으나 차이의 표준편차가 커서 공공기관과 평가기관의 견해 차이가 큰 것으로 분석되었다.

Korea Meteorological Administration has promoted the next generation urban and rural smart weather service project. The purpose of this project is to provide the necessary information to urban and rural districts by using the subdivided meteorological information. This study attempts to assess the value of the next generation urban and rural smart weather service project by using contingent valuation method. According to estimating result, annual mean willingness to pay per household for the next generation urban and rural smart weather service project is 2,947 won.

Under traditional analysis of the capital budgeting, NPV, it is assumed that management cannot react to deviation from the expected scenario of cash flow at the time of evaluation. In practice, however, it is less likely that the expected scenario will come true when new information arrives and uncertainty is resolved. Uncertainty and risk can be influenced through 'managerial flexibility', which becomes a central instrument for value creation. Real option framework including option to defer, option for staged investment, option to alter, option to abandon, option to switch, etc. takes this managerial flexibility into account. Therefore, it is more appropriate to use real option method to evaluate the project than the traditional DCF(discounted cash flow) tool if the firm has high volatility of the expected returns.

The purpose of this study is to analyze the outcomes of experts' survey for Cultivation techniques of good seed bulb in garlics program, purpose of introduction, and performance analysis this program. As a result of survey on new technology adoption to be cultivated in cultivation techniques of good seed bulb in garlics, technique satisfaction scored the highest with 4.3 points whereas innovation scored 4.21 points. On the other hand, risk scored the lowest with 2.53 points. Also, using BMO model business attractiveness and business fit scored 44 points, 45points respectively. Thus, the project rate of success were analyzed by more than 80 per cent. Finally, the management performance is analyzed on the garlic farms by selecting the highest awareness collected. As a result of effects after new technology adoption, 43% of the surveyees stated that the relative management costs dramatically decreased, and increase in production.

After the global financial crisis, domestic construction industry has gone through a rapid recession. This resulted in gradual market shift towards architectural remodeling. Architectural remodeling not only improves residential environment but it has many advantages such as increase of each unit's exclusive area, free space within the horizontal or extension of an annex building, and increase number of household through splitting the household of bigger pyeong, etc. However, in case of the Korean market for apartment remodeling, due to various regulations and problem with business promotion procedures, majority of business is slow despite the figure that remodeling volume is not that small. Also, feasibility study which decides to push ahead public house remodeling business will have a flaw using net present value's law; it has a flaw of not considering properties of each phase of remodeling business and future's uncertainty. Hence, this research will improve the problem of traditional value assessment method of net present value's law. It will also consider one of the real options such as binomial model in order to supplement NPV which is used in current feasibility study. This research was based on real successful cases of public house remodeling and it was possible for feasibility study which was more realistic and valid. This research provided foundation for development of Korean public house remodeling market. There is high anticipation of increasing the validity by improving the problems of current feasibility study and economic efficiency assessment.

In 1995 of May, the Ministry of Construction and Transportation (NOCT) developed the First Nation-wide Master Plan of GIS. It is set up in response to an increasing and various demands on spatial informations. Until now, a set of diverse projects related to spatial information have been proposed and executed. However, cost-benefit analysis of investment and decision making for alternatives have not been carried out appropriately because scientific evaluations for obtaining efficiency and economical validity of investment have been deficient. Optimum decision making for projects based on itemized priority order using effect or cost of proposed alternative plan is a fundamental expedient for demonstration of propriety of projects and enhancement of efficiency of investment. From such understanding, this paper applied the analytic hierarchy process (AHP) technique to the cost required to construct a GIS so that analyze the weight of each cost factor.

In case of low benefit project with low traffic or high-priced project, existing analysis of cost and benefit tends to present a low feasibility. However, considering the improvement of environment, intensification of disaster prevention, public stability of countryside area and formation of good scenery, these projects can have a feasibility. This paper analyzes and summarizes the indirect benefit of some ripple effects, caused by road projects, and presents the methodology and process in order to change the indirect benefit into monetary value.

Even though the pre-feasibility study was introduced in 1998, it mainly has focused on transportation social overhead capital(SOC) such as road and railroad. Last year, however, the government newly launched R&D project area for the pre-feasibility study. This paper tries to analyze the pre-feasibility study methodology and system that applied to R&D facility, cluster, and sized R&D infrastructure projects. In depth study of economic, policy, and AHP analysis, this paper shows that the preliminary feasibility study have some caveats and suggests a way of improvement for making up for limitation. Main suggestions are as follows; First, to improve the fit in R&D sector analysis, using consistent method is important. Second, technology analysis is essential for R&D evaluation. Third, technology experts should take part in AHP analysis.
