This study estimated the social benefits of establishment 01 the Taehwa Field Ecology Park in Ulsan Metropolitan City, using CVM(Contingent Valuation Method) with multiple choices in consideration of respondent's uncertainty. The estimation results 01 lour logit models show that the probability of willingness-to-pay increases significantly with higher income, higher evaluation on the relevancy of establishment of the Park, and male gender, and decreases significantly with the bidding price. Truncated mean household WTP is estimated as 2,409.4 KRW in the MBYES model with the most efficient estimates of WTP among four models. On the basis of the WTP estimates, the present values of total social benefits in Ulsan Metropolitan City are estimated as 236.5 bill ion KRW when applying the 5% discount rate. This result shows that the present values of total social benefits are greater than the total costs in all models, and thus may prove the economic relevancy of the investment for the ecology park establishment.

It is time to develop new renewable energy that could fundamentally replace fossil fuel, which has been increasingly needed due to environmental pollution and energy security. Korean marine bio-energy development project is planned to produce 50% of total bioenergy. This study attempts to measure the greenhouse gas emission reduction benefits of marine bio-energy development project through contingent valuation method. Single bounded dichotomous choice (SBDC) is applied with spike model. The results show that the average willingness to pay are estimated to be KRW 4,190 at SBDC, per household per year. If the result has been expanded to the region which is survey conducted, KRW 50.1 billion annually. These quantitative information can be usefully utilized in the cost benefit analysis to implement project and policy-making for the industrialization of marine bio-energy development project.

Reduced greenhouse gas effect induced by LID (Low Impact Development) technique application in tramway construction was quantified to increase environmental benefit as part of an overall economic assessment. In addition, by application of penetration type permeable blocks, the effect of the urban water cycle was examined as a special assessment item in the policy analysis. The carbon emission ratios of the permeable turf block, according to the turf coverage rate (100%, 50% granite, and 50% HDPE), against the concrete track construction were -184.7%, -127.3%, and -116.3%, respectively. The carbon emission ratios of permeable blocks with granite and HDPE were 30.1% and 52.5%. In the case of the penetration type permeable block, it was possible to store rainfall in the block until 90mm/hr of rainfall intensity (94.3% of water reserve rate); therefore, this method was effective as part of the urban water cycle system. As a result, an increased environmental benefit from LID technique application is expected in tramway construction; this needs to be considered as a policy factor in AHP analysis.

Due to environment problems in end of Life Vehicle in the country, the interest in remanufacturing is heightened than ever. In this study, it is important to quantitatively evaluate the economic effect of the introduction of the automotive remanufacturing business and analyzed cost-benefit for the three species of bumpers, doors, fenders, which is relatively lower remanufactured automotive component. The results showed that cost-beneift of each parts were analyzed 54,000 per one part, and if remanufacturing were 50%, benefits were to occur with a profit of 226,060 won. Thus, remanufacturing of bumpers, doors, fender resulted a significant benefit, and then it is possible that remanufacturing company have enough economic value for remanufacturing.

오래전부터 물은 누구나 사용할 수 있는 자유재로 인식되었지만, 산업혁명 이후 폭발적으로 증가하는 인구와 환경오염 문제로 인해 인류가 사용할 수 있는 수자원이 그 수요에 비해 공급이 줄어들었으며, 이로 인해 자유재로 인식되어 왔던 수자원은 점차 그 가치를 매기는 경제재로 인식이 바뀌고 있다. 하지만 다른 경제재와 다르게 자연자원인 수자원은 환경재, 공공재라는 인식이 강하고, 더불어 공급의 불확실성으로 인해 일반적인 시장경제가 적용되기 어렵고 경제적 가치를 산정하기가 쉽지 않다. 이에 최근 수자원 전문가들은 공급이 한정된 수자원을 효율적이고 합리적으로 배분하기 위해 수자원의 경제적 가치를 산정하는 연구를 진행하고 있다. 예를 들어, 미국 캘리포니아주의 경우 수자원의 용도별, 지역별 경제적 가치를 산정하여 이를 용수배분에 적용한 CALVIN모형(CALifornia Value Integrated Network)을 개발하여 실제 주정부의 수자원 활용계획에 적용한 사례가 있다. 우리나라의 경우 구체적으로 수자원의 용도별, 지역별 경제적 가치를 산정하고, 이를 실제 물 배분 계획에 적용한 사례는 드문 상황이다. 본 연구에서는 국내 실정에 맞는 수자원의 용도별 경제적 가치를 추정하고 편익함수를 산정하는 방안을 연구하였다. 수자원의 용도를 생활, 공업, 농업, 하천유지 용수 등 네 가지로 구분하여 각 용도별로 용수의 경제적 편익을 분석하고 이를 토대로 용수별 편익함수와 경제적 가치를 산정하는 방안을 제시하였다. 본 연구를 통해 제시될 수자원의 용도별 편익함수는 향후 개발예정인 수자원-경제통합 물 배분 모형에 적용될 것이며, 나아가 수자원의 효율적인 배분 계획 및 정책 마련에 기여할 수 있을 것이다.

The aim of this paper is to calculation benefit cost for development of Hwawon leisure & tourism complex. To calculation benefit cost, this paper propose a advanced travel cost method(ATCM) which is to consider Improved travel cost method(ITCM) and variable traffic units with confidence degree cf decision-maker. At the result of calculation, total benefit costs are 292805 million won at 52% of confidence degrees and 10% discount rates.. Also total benefit cost is 304517 million won at 4% of GDP growth rate is 4%.

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.
