  • U.S. National Research Council proposed benefits framework for energy R&D project as economic benefits, environmental benefits, security benefits and knowledge benefits. Following this framework, U.S. National Renewable Energy Laboratory evaluated the projected benefits of Federal Energy Efficiency and Renewable Energy Programs in the indicators of energy-expenditure savings, energy system cost savings, $CO_2$ emissions reductions. oil savings, natural gas saving and avoided additions to central conventional power. As this result, geothermal energy have predominant position in the energy-expenditure savings, natural gas saving and avoided addi t ions to central conventional power to FY2050. The projected benefits, in monetary value, of the whole supply-potential of geothermal energy in Korea were evaluated as 480.2 billion Won, 43.1 billion Won and 135.8 billion Won for the private energy-cost savings, social environmental-cost savings, and import energy-cost saving, respectively.

  • Effects on feed intake, liveweight gain and economic benefits of supplementing lambs with urea molasses blocks, were studied. Forty eight crossbred lambs were divided into 6 groups and assigned randomly to grazing on native pasture (CONT) or along with supplements of Commercial ration (COM) and urea molasses blocks (UMBs) containing two levels of cement and calcium oxide as a binding agent. Analysis of variance revealed highly significant (p<0.01) differences in dry matter (DMI, g/day), crude protein (CPI, g/day) and metabolizable energy (MEI, MJ/day) intakes. Differences in liveweight gain (LWG, g/day), feed conversion ratio (FCR) and net economic benefit of supplementation were also highly variable. The intake of DM, CP and ME varied from 974 to 1002, 66-70 and 7.6-8.4 in lambs supplemented with UMBs, significantly (p<0.01) greater than 848, 52.5 and 5.6 in lambs supplemented with COM or FCR and net economic benefits (54.3; 57.8; 17.1 and 1.96; 2.4) in lambs supplemented with COM and UMB-2, were CONT or supplemented with UMB-1, UMB-3 and UMB-4 respectively. Factors responsible for differences in feed intake, liveweight gain and economic benefits, are discussed.

  • PURPOSES : This study is to analysis for benefit and construction cost in underpass for small vehicles. METHODS : The study was performed using the traffic software VISSIM 5.20 for analysis on a variety of traffic conditions and analysed of benefits of changes through analysis of travel speed and travel time after modeling of existing underpass and small vehicle underpass. RESULTS : Results of this study, the benefits will be reduced by the introduction underpass for small vehicles were analyzed because heavy vehicles use the intersection above the underpass. However, it was required economic analysis considering both the benefits reduction and the construction costs reduction because it has the effect of reducing the construction cost. Showed that the difference in benefit changes depending on the v/c and heavy vehicles ratio and construction cost was difference by types of underpass. As a result of performing economic analysis with total benefits and construction cost, it was analyzed to be economical in underpass over a certain size. CONCLUSIONS : The result of this study are expected to be able to contribute to reviewing for feasibility due to the small vehicles underpass introduction and economic analysis. The study is case study to the underpass in Daegu. Therefore, the future requires the calculation of benefits reflect a wider range of traffic conditions and the economic analysis to construction cost calculation for various types of grad separation facilities.

  • As vehicle sharing service is being widely used in China. The sharing economy appeared to be a way to make people's lives more convenient and to utilize limited resources efficiently. Sharing economy companies have created an app to satisfy users' needs with providing more benefits. Although research on vehicle sharing services has been continuously conducted at the level of the sharing economy, there are not many empirical studies related to the perception of the sharing economy from the consumer's point of view. In this sense, this study considered the perceived relationship benefits (social benefits, economic benefits, psychological benefits, and functional benefits) of Didi chuxing service as the key independent variables influencing users' confirmation and satisfaction, And suggests that users' confirmation and satisfaction are the key determinants of Didi continuance intention . To test the proposed research model, this study conducted structural equation model using 268 data collected on the users who have experience of Didi service. According to the empirical analysis results, This study verifies that: First, social benefits, economic benefits, psychological benefits, and functional benefits are determinants of user's satisfaction. Second, expectation confirmation depends on economic benefits, psychological benefits, functional benefits and social influence, meanwhile, social benefit has no effect on expectation confirmation. Third, expectation confirmation is proved to be a positive predictor of users' satisfaction. Finally, this results indicate that continuous use intention is determined by users' satisfaction.

  • In this study, we analyzed the economic feasibility of the swimming crab (Portunus trituberculatus) fry releasing program in the West Sea of Korea. The catch rate of released fry in 2010, measured by genetic markers, was applied to the economic surplus method to estimate benefits. As a result of our analysis, the B/C ratio, as an indicator of economic evaluation, was determined to be 2.168, which means that the releasing program was economically feasible. And it was shown that the benefits to consumers is six times greater than the benefits to producers, confirming the necessity of the releasing program as a public work.

  • 울릉 연안바다목장 사업은 조성사업을 위해 5년(2013~2017년) 동안 총 50억원(국비 25억+지방비 25억)의 사업비가 투입되어 어장조성, 자원조성, 종자방류, 효과조사 등을 수행하였다. 경제적 편익은 크게 어업순소득 증대효과와 어업 생산비용 절감 효과를 포함한 직접적 효과와 유어낚시 편익 증대효과와 연안바다생태계의 보존가치를 포함한 간접적 효과로 구성한다. 증분율(1안)을 바탕으로 분석한 결과 현존량 평균기준과 총량기준에 의한 어류어업 순소득 증대효과는 '283,958.79천원/년'으로 추정되었고, 어류어업 생산비용 절감효과는 '51,695.46천원/년', 비어류어업의 생산비용 절감효과는 '6,420.65천원/년'으로 추정되었다. 울릉군 유어낚시객 263명을 대상으로 조사한 결과 1년 동안 울릉도 유어낚시 횟수는 평균 7.9회, 1일 유어낚시 어획량은 평균 5.85kg, 왕복여행비용은 평균 659만원, 조획증가율은 평균 12.7%, 가계소득은 평균 462.8만원인데, 이에 따른 울릉도 연안바다목장의 유어낚시의 연간 경제적 편익은 '29,944.75천원/년'으로 추정되었다. 이와 같이 울릉도 연안바다목장 경제성 분석결과 시장가치만을 적용한 보수적 경제성 분석에 의하면 사회적 할인율 4.5%에서의 순현재가치(NPV)는 -1.25억원, 내부수익률(IRR)은 4.30%, 편익/비용비율(B/C ratio)은 0.98로 평가되어 경제적 타당성을 약간 확보하지 못하고 있다. 비시장가치를 포함한 확대된 경제적 타당성 분석결과는 순현재가치가 30.9억원, 내부수익률이 11.3%, 편익/비용비율이 1.49으로 보존가치를 포함할 경우 보수적 방법에 의한 것보다 상당한 경제성을 가지고 있는 것으로 평가된다.
