Background: The purpose of this study is to emphasize the importance and necessity of the government's old-age preparation service by measuring the economic value of the old-age service and the policy direction and policy implications of the government's old-age preparation service project. Methods: Contingent Valuation Method (CVM) was used as an analytical method. CV methodology was used to calculate the Willingness to pay (WTP) for old-age preparation service and its value was estimated and the economic benefit of the project was estimated. Results: As a result of the analysis, the average monthly payment amount for the old service was calculated as 5,100 won, and the annual average payment amount was estimated to be 61,197.1 won. Conclusion: The present value of the benefit for 10 years with the discount rate of 5.5% is 484,651 won. Based on the value of peruser benefit, the total benefit value calculation result of the old-age preparation service considering the Willingness to pay for the next 10 years shows that the total benefit value of the old service, which occurs during the period from 2016 to 2025(10 years) was estimated at 415.1 billion won. As a result of calculating the benefit for each scenario, the present value of basic service is higher in all scenarios than the linked service.

The purpose of this study is to suggest the benefit-cost analysis for photovoltaic system in greenhome. Perspectives of benefit-cost analysis for photovoltaic system in greenhome is participant, non-participant, administrator and nation. This study identifies the cost and benefit components and benefit-cost calculation procedures from four major perspectives : participant, non-participant, administrator and nation. The results of benefit-cost analysis from each perspective can be expressed in a variety of ways, but in all cases it is necessary to calculate the net present value of photovoltaic system impacts over the lifecycle of those impacts.

Purpose: The objective of this study is to verify the economic validation of quality management integrated train freight car by analyzing economic evaluation indicators such as benefit and cost, net present value, and inter rate of return. Methods: First, we itemize benefit and cost field by reviewing literatures; Benefit consists of 1)Safety, 2)Operation, and 3)Maintenance; Cost consists of 1)Set-up fee, 2)Wireless internet fee, and 3)Cloud storage using fee. Second, based on these estimated values, we conduct an economic evaluation analysis. Among them, benefit and cost, net present value, and internal rate of return are selected. Results: As a result, all estimated values are highly over criterion of economic validity($$B/C{\geq}_-1$$, $$NPV{\geq}_-0$$, $$IRR{\geq}_-R$$); 1)benefit over cost ratio is 28.22, 2)Net present value is 8,121.66million KRW, and 3)Internal rate of return value is 2272%. Conclusion: The findings of this study will help making a decision when train industry adopts IoT technology for improving the effectiveness.

Environmental pressures from such sources an economic condition, the government and inter-institutional competition create managerial challenges. Economic pressures may be forcing dietetic dept, in hospital to utilize cost∙benefit analysis to assist them in their problem solving. Cost∙benefit analysis have been widely used in business, industry and many other fields with only limited application to foodservice. Due to the lack or this information the purposes of this study were to identify use of cost∙benefit analysis in hospital foodservice system to evaluate the economic efficiency of alternatives, and to make recommendation for operation system change. Using the cost∙benefit method, cash flows are separated into cost and benefits. For an alternative to be selected, indicators, such as NPV, benefit-cost ratio (B/C ratio) with 5% discount rate per annum. The sensitivity analysis was also conducted with difference rate 3%, 7% respectively and reduced employee payroll change. The result of this study can be summarized as follows : 1. The total cost of investment for operation system change was 390,570 thousand won and the total benefit through operation system change was 865,808 thousand won. 2. Net present value(NPV) for 5 years was 475,239 thousand won and benefit-cost ratio was 2.22. 3. In sensitivity analysis with different discount rate 3%, 7%, benefit-cost ratio was 2.25, 2.18 respectively, with total reduced employee payroll change, benefit-cost ratio was 2.86. In conclusion, total benefits were exceeded total costs. Therefore, the project of operation system change in hospital foodservice was found to be economically efficient.

Fishing population has been increasing with national income improvement and the five-day workweek in Korea. Recently commercial fishing facilities like pay fishing pond are emerging as demand of saltwater fishing increases, unlike the past when inland fishing was prominent. In order to do businesses, economic analysis should be done in advance. This study aimed to make an Economic analysis of Uljin pay-fishing place by estimating the cost and benefit, and calculating the rate of economic return. The results show the Uljin pay-fishing place's net present value of 3.5 billion won, internal rate of return of 14%, and benefit cost ratio of 1.16 at 5.5% social discount rate.

The main purpose of this study is to analyse economic feasibility of low-carbon-oriented gear for anchovy boat seine. The results of benefit/cost analysis showed that use of the low-carbon fishing gear is economically feasible. Considering the fuel saving and relatively low $CO_2$ emission by reducing the resistance of gear, net present value by such type 1 gear improvement was estimated about -2,490 ~ -1,580 million won with the benefit-cost ratio 0.81~ 0.88. And net present value by such type 2 gear improvement was estimated about 6,540 ~ 7,780 million won with the benefit-cost ratio 1.79 ~ 1.94. Development of lowcarbon trawl gear would render significant contributions to reducing $CO_2$ emission in fishing operations and lead to reduce fishing costs due to fuel savings.

본 연구는 북한 산림복원을 생태계 서비스의 관점에서 비용-편익 기반 경제적 가치로 확인하였고, 산림복원 형태에 따른 경제성을 비교하였다. 특히 산림복원에 따른 편익을 탄소저장, 수자원공급, 토양유실방지, 재해저감 등 생태계 서비스로 분류하고 경제적 가치로 환산하여 종합적 편익을 산출하였다. 산림복원 시나리오에서는 최근의 북한 조림실적과 산림정책을 고려하여 '단독조림 시나리오'와 '산림협력 시나리오'를 구성하여 동일한 복원기간이나 조림의 양적 물량 차이를 시나리오로 도출하였다. 단독조림 시나리오에서는 향후 20년 동안 3조 8,294억원의 비용으로 80만 ha의 산림을 복원하여 6조 8,684억원의 편익이 발생할 것으로 산출되었다. 순현재가치로 경제성을 평가하였을 때, 3조 390억원으로, BCR은 1 이상이었다. 산림협력 시나리오에서는 10조 531억원의 비용으로 220만 ha의 산림을 복원하여 18조 8,909억원의 편익이 발생할 것으로 산출되었다. 마찬가지로 순현재가치로 경제성을 평가하였을 때, 8조 3,599억원이며, BCR은 1 이상이었다. 두 시나리오에서 모두 BCR은 1 이상으로 경제성을 갖는 것으로 도출되었으나, 예상되는 편익의 양에는 큰 차이가 있었다. 다만, 조림면적에 따른 단순화된 비용-편익 분석이므로, 경제성(BCR)이 유사하게 나타나는 한계가 있으며, 조림속도나 생물리적 차이를 고려하지 않았다. 결론적으로 산림복원은 비용보다 편익이 높은 사업이 될 수 있으며, 산림협력을 통해 그 가치를 증진시킬 수 있다. 장기적으로 이러한 경제성이 근거가 되어 기업과 국제·민간기구 등의 협력을 통해 다양한 형태의 산림협력이 추진되길 기대한다.

제조업을 중심으로 분석한 환경관련투자 효율성의 주요 연구 결과는 다음과 같다. 내부수익률과 편익의 현재가치를 가변비용절감부문, 투자비용절감부문, 임대수입부문으로 분해함으로써 기존 연구의 범위를 확장했다. 그리고 단기총비용과 임대수입의 역할을 탐구하여 편익의 현재가치는 편익의 크기만을 나타내는 반면, 내부수익률은 효율성의 존재여부를 나타냄을 발견했다. 그리고 내부수익률과 시장이자율을 비교하는 투자효율성 방법론으로 환경관련투자와 관련된 투자효율성과 편익을 분석함으로써 사후 비용편익분석을 수행했다. 그 결과 환경투자, 공해방지투자 모두 비효율적인데, 공해방지투자가 환경투자보다 더 비효율적임을 발견했다.
