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.

This study attempts to estimate economic benefits in terms of cost sayings and qualitative effects resulting ken implementation of new vehicle maintenance information system. It is widely expected that the effect of new vehicle maintenance information system will be significant in cost savings by information sharing and electronic documentation. To evaluate the economic feasibility of new system implementation, the study conducted seven subsystems case studies on the vehicle maintenance information system of Seoul Metro. Economic benefits are estimated by measuring the time savings, in turn, are calculated into cost savings by multiplying the average wages per hour of employee. The result of case study showed that over the 20 billion Won will be saved owing to new vehicle information system implementation. In conclusion, this study will contribute to the field of practices for the most, in evaluation of the economic benefits resulting from new information system implementation in the railway organization.

A coastal marine ranching project in Uleungdo had been conducted for 5 years from 2013 to 2017 with investment costs of 5 billion won, for the special purpose of the deployment of artificial reefs, the release of young fishes. The paper focuses on an ex-post analysis of the economic feasibility for the project after completing the project, which is apart from a preliminary viability. For economic analysis, the economic benefits are derived from direct benefits including increasing effects of fisheries income and saving effects of harvesting costs, and indirect benefits including increasing effects of recreational fishing and preservation effects of coastal marine ecosystems while economic costs include releasing and purchasing costs of artificial reef and juvenile fish, R&D costs, maintenance costs and harvesting costs. The result shows that the project should not be accepted according to NPV=-0.125 billion won, IRR=4.5% and B/C ratio=0.98 under Scenario 1 which considers direct benefits and indirect benefits excluding the preservation values, while the project should be accepted under Scenario 2 indicating NPV=30.9 billion won, IRR=11.3% and B/C ratio=1.49 which considers the direct benefits as well as the indirect ones including the preservation values, based on 4.5% of the social rate of discount.
