본 연구는 해외조림을 통한 목재의 안정적 확보를 기하기 위하여 태국을 대상으로 투자환경과 수익성 분석을 하였다. 연구결과 태국은 정책적으로 산림률을 현재 25%에서 40%로 유지하려고 노력하고 있기 때문에 조림을 널리 장려하고 있으며, 조림과 목가공산업(합판, 베니어, Chip board, Hard board)은 최소한의 투자요건을 요구하는 업종으로 구분하고 있어 다른 분야보다 상대적으로 유리한 입장이다. 태국에서 현재 가장 역점을 두고 있는 조림수종은 유칼리로서 특히 펄프용으로 이용할 경우 유칼리의 벌기령은 4~5년으로서 매우 짧고 IRR도 29.1~59.3%로 매우 높게 나타났다.

This study suggests a method for calculating the benefits of water pipe renewal based on an estimate of the water supply suspension risk. The proposed method based on five benefit items is more direct and specific than other benefit estimation methods. In addition, a methodology evaluating the economics of pipe renewal based on pipe failure rate is proposed for estimating the optimal renewal point from an economic perspective. By estimating the optimal renewal period based on a yearly benefit cost ratio per pipe in a case study area, it was possible to draft an optimal renewal plan for the subject region from an economic perspective. Compared with other methodologies, a reasonable optimal renewal period was derived from an economic point of view. The result of this study may be used to develop future water pipe renewal plans. Moreover, the proposed methodologies and results derived from this study can be applied to asset management plans.

본 연구는 공공도서관 건립 타당성조사보고서에 있어서 경제적 타당성 접근방법과 정책적, 기술적 타당성 접근방법을 비교$\cdot$분석하고 문제점을 구명하였다. 경제적 타당성 분석에서 사용된 비용편익분석은 편익추정과 할인율 적용에 문제가 있는 것으로 나타났으며 정책적, 기술적 타당성 분석은 건립이 확정된 사업을 합리화하는 수단으로 잘못 활용될 수 있는 문제가 나타났다. 본 연구의 결과는 공공도서관 건립을 계획중인 관련기관에서 타당성조사를 준비하는데 유용한 자료가 될 것으로 기대한다.

This paper presents the economic validity with the cost/benefit analysis on establishing R&D Supreme Academy. To evaluate the profitability of R&D Supreme Academy, willingness to pay (WTP) is measured by contingent valuation method (CVM) and then the net present value (NPV), internal rate of return (IRR) and benefit/cost ratio(BCR) are calculated. The results of economic evaluation verified that the establishment of R&D Supreme Academy is timely and effective in an economic perspective.

좌석 안전띠는 자동차 안전장치 중 차량의 안전상 가장 중요하고 효과적인 장치로 알려져 왔다. 우리나라의 경우 운해중 안전띠의 착용률, 특히 뒷좌석의 착용률이 낮다. 최근 조사 자료에 의하면 뒷좌석의 안전띠 착용률은 20%의 수준이다. 최근 좌석 안전띠 미착용 알림장치(Seat Belt Reminder, SBR)를 의무화하는 것을 고려중에 있다. 본 연구는 SBR의 의무화할 경우의 도입효과에 대한 분석이다. 본 연구에서 안전띠 착용효과는 해외의 연구사례(Evans(1991) 모형)를 준용하였다. 주요 변수로 안전띠 초기착용률은 국내 조사자료, SBR로 인한 목표 착용률은 운전자 순응도에 따른 시나리오에 따라 추정하였다. 연구 결과, 좌석안전띠 미착용 경고장치의 운전자 순응비율이 90%이상일 경우 매해 119명의 사망자의 감소효과를 가져올 것이고, 편익비용비가 1.84에 달할 것으로 분석되었다.

Since 1989, 9 major complex have been invested with government funds, for the purpose of developing agricultural tourism to increase agricultural income and job opportunity, as well as providing urban population leisure opportunity. However, systematic and comprehensive approaches were rarely done in analyzing its economic impacts. This study, therefore, focuses on analyzing tourism effect and its economic value and implication for a representative rural tourism site,"Daeho rural tourism complex". To analyze travel pattern, expenditure pattern, and degree of satisfaction from travel to Daeho complex, Travel Cost Method(TCM) was employed based on survey method. Results from linear model with statistical significance implies that tourism benefit for each visitor is 28,373 won and total annual benefit for the Daeho site is 7 billion won. Considering annual benefit stream, the present value of total benefits are 132.9 billion won and 70 billion won at 5% and 10% of discounting rate, respectively. Using the values of benefit estimated from this study and investment cost, B/C ratio, IRR, and NPV were calculated to be 1.01, 1.67 billion won, and 5.19% at 5% of discounting rate. These results could be directly compared with the previous analyses.

The purpose of this study is to measure the cost-benefit of a road construction project in Vietnam through international development cooperation, which includes private grants and Official Development Assistance(ODA). In developing countries, it is difficult and costly to use data on markets, the CVM(Contingent Valuation Method) to measure the WTP(Willingness-to-Pay) as the benefits of road construction are used. A total of 232 villagers in 16 villages of Lao Cai Province in Northern Vietnam have been surveyed. It is found that the Benefit-Cost Ratio(B/C) in all 3 models are found to be well over 1.0, ranging from 2.8 to 3.64 with the discount rate of 0.06. These BC ratios imply the road construction project in Lao Cai can be justified. Also, it is found that the shortened travel time is the most relevant factor for WTP among direct benefits and the enhanced academic achievement of the children is the most relevant factor among indirect benefits, due to easier and faster access to schools, which in turn increase the school attendance rate. The result of this study can be used to justify other similar projects in Vietnam, even though the benefits may have to be reassessed in other countries.

The main purpose of this research is to analyze economic feasibility of biodegradable sonw crab gill net model project. The results of benefit/cost analysis show that use of the biodegradable gear is economically feasible. Assuming that the rate of gill net lost is 5 percent, net present value was estimated 311,898,282-590,533,375won, benefit-cost ratio 1.816-1.923 and internal rate of return 7.96-10.59%. The development and diffusion of biodegradable fishing gear appear to make a significant contribution to fisheries resource conservation and marine ecosystem protection. In addition, biodegradable gear production firms may have a good opportunity of exporting it to other coastal states, depending on the progress of WTO subsidy negotiation.

Feasibility which is complimented before Social Overhead Capital Project and National Policy Project is analyzed by economic and political benefits. The projects will be performed if the benefits are bigger than the project cost. In this study, feasibility was examined at various viewpoints on sewer rehabilitation projects implemented with private capitals. To achieve the feasibility analysis, the B/C (Benefit/Cost Ratio), IRR (Internal Rate of Return) and the returns ratio of the Build Transfer Lease project implemented in 2007 at W city were estimated. At the same time, the correlation with B/C and benefit sensitivity of concessionary rate fluctuation were analyzed to evaluate the efficiency and feasibility of the seven sewer rehabilitation projects promoted by a local autonomous entity.

This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.
