The purpose of this study is to evaluate the economic validity of artificial reefs facilities and seeds release programs in Jeju Trial Sea Farm Project for raising fishing people’s revenue. The results of this study show the artificial reefs facilities and seeds release programs have net present value of 15,962.63 million won, internal rate of retrurn 13.86%, and benefit-cost of 1.912 under a 5.5% social discount rate. This suggests that in Jeju trial sea farm project, artificial reefs facilities and seeds release programs increase fisherperson’s revenue.

This study has performed comparative analysis on benefit indicators in agricultural irrigation and drainage project cases between Korea and Japan. The irrigation and drainage project with publicity should do economic analysis of direct benefit factors as well as indirect benefit factors. However, traditional economic evaluations are used that benefit factors are lack of consistency and focused on direct benefits. Therefore, the purpose of this study was to develop indicators for the economic evaluation of irrigation and drainage projects. We conducted a case study between Korea and Japan. The resulting benefit factors was divided into direct factors and indirect factors. The direct benefit factors were increase in income, cost savings. The indirect benefit factors were protection of property due to flooding, agricultural promotion, aesthetic improvement. The implications of this study are that the indicators of economic analysis can be evaluated and easily applied. Moreover, these indicators could promote the feasibility of economic analysis.

The waste treatment cost and energy production benefit of Wonju city RDF plant, the first RDF manufacturing plant in Korea, were investigated in this study. All plant operation data, like total weight of received wastes, produced RDF and separated rejects in processes have been fully recorded for mass balance calculation of the plant. Also all consumed oil and electricity have been recorded for energy balance calculation. The results showed that the waste treatment cost not included the RDF sales price of 25,000 won/ton-RDF was 139,316 won/ton-MSW and it went down to 128,640 won when included the RDF price in 2011. Produced RDF was 42.7% of total received waste in weight. Three components analysis by mass balance calculation of total received waste showed that Wonju city's MSW was 34.0% of combustible, 35.0% of water and 31% of incombustible respectively. Energy effect was found that total amount of produced energy was about 4 times more than that of consumed energy. Analysis data for 5 years since 2007 were summarized and shown in this study.

댐이 건설된 이후 댐직하류 하천구간은 하천구역내 사유지 경작과 하상주차장 등의 입지, 사주가 발달하여 하폭감소에 의한 문제가 발생하였다. 특히 하천정비의 미흡으로 홍수시 하천통수능력이 감소하여 유역전반에 영향을 미치고 있다. 댐 운영조건도 일부 제약을 받고 있는데 이의 해소를 통한 댐 기능의 회복과 운영의 효율성 제고가 하천의 치수 안정성 확보와 함께 개선대책이 필요하였다. 따라서 댐 운영관리개선과 연계된 댐직하류 하천정비사업이 시행되고 있는데 사업의

오늘날 세계 해운 시황의 호황에 따라 컨테이너 정기선 부분에서는 선복량의 부족 현상이 초래되고 있으며 선사는 신조선 발주와 중고선 구입 및 정기 용선을 통해 부족한 선복 문제를 해결하고 있다. 특히, 정기선사들은 신조선 발주시 TUE당 운송비용을 절감하기 위하여 컨테이너선의 대형화를 적극적으로 추진하고 있다. 이러한 대형 컨테이너선박의 발주를 통한 선복 확보 방안은 차후 선복 과잉 문제가 발생될 수 있음이 컨테이너선의 실증 분석을 통해 연구되었다. 본 논문에서는 2008년 이후 대형 컨테이너선이 대거 인도되는 시기에 선복량의 과잉공급으로 인한 해운시황의 변동에 따른 선사의 대응 전략 방안에 대해 연구한다. 즉, 경제성 분석을 바탕으로 한 초대형 컨테이너선의 Space Chartering 시점에 대한 선사의 전략 수립에 대해 논의한다.

There are recently many studies on evaluating the economic value of multi-functionality of rural areas. However, the regional difference of economic value leads a problem of different evaluation on its economic value for each region in its application to government policy. This problem causes an increase in cost because it creates restriction in policy decisions which put their importance on the time of their execution. This study investigates the propriety of value transfer using Meta Analysis after evaluating the social and cultural value of rural areas among their functions based on CVM model. It finds that the regional difference in the willingness to pay is 0.13% to 31.42%.
