Objectives: This study aims to evaluate the economic efficiency of a nutrition management program for children under 5 years of age in Kenge, Kwango District, Democratic Republic of the Congo (DR Congo) from 2014 to 2016. Methods: The economic efficiency of a nutrition management program for children under 5 years of age who have recovered from malnutrition status was evaluated using a cost-benefit analysis. The costs were analyzed according to the executed budget incurred during the project period. The benefits were estimated as the monetary value of the saved lives of children under 5 years of age. The economic efficiency of the program was determined by the Benefit-Cost Ratio (BCR). The BCR was calculated by dividing the total discounted benefit by the total discounted costs. The project is economically efficient when the BCR is greater than 1. Results: The costs of the nutrition management program were calculated as 1,677,609,648 Korean Won (KRW). A total of 2,466 children survived with improved malnutrition status through this program. The benefit for the reduction of mortality for children under 5 years of age was estimated to be 6,814,354,467 KRW, the estimated value of life for 2,466 children. The BCR was 4.06. Conclusions: The nutrition management program for children under 5 years of age in DR Congo was found to be a cost-effective project. Successful and efficient Official Development Assistance (ODA) for a health project requires integrated and comprehensive strategies and specialized international development consulting to improve efficiency. Future nutrition management programs should take into account the national health program to maintain the sustainability of the project.

The objective of this study is to estimate the cost and benefits of street trees for their planting types, specifically, single row, single row+bottom, double row, double row+bottom. Different planting types are compared and analyzed by using Net Present Value (NPV) and benefit-cost ratio (BCR). Existing data are collected from the literature reviews for the use of meta-analysis method for estimating cost and benefit. The elements for analyzing costs are management and planting costs, and benefits are air purification, energy saving and landscape view. The discount rate is applied at a minimum of 3% and a maximum of 5.5%. The unit used in this calculation is km/year. The result shows that the net benefit is highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR is the highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR reaches the break-even point from 9 to 17 years depending on the planting types.

This study analysed the economic feasibility per hectare of grow out phase production of Oyster farming by rising water temperature in Ocean. Elevated Water temperature by climate change had a bad influence for oyster production and economic feasibility. In the case of production units, the total output of oyster decreases from 213,840 to 205,594 units. Using cost-benefit analysis with discounting rates (5.5%), we estimated the net present value (NPV) and benefit cost ratio (BCR) until 2100 years. The model results showed that the NPV without water temperature rise was 1,565,619,893 won and the NPV with water temperature rise was 1,540,493,059 won. Also, BCR estimated that the former was 2.095 better than the latter was 2.077. To summarise, the economic effect per hectare of water temperature rise in ocean did the damage to the economic loss about 25,126,834 won.

The purpose of this study is to estimate the economic value and productivity achieved through a reduction in fishing vessels engaged in coastal and offshore fisheries. We found that the value of increasing catch by types in offshore and coastal fisheries was about 17,338 billion won. To examine the economic value, a cost-benefit analysis was applied. This is based on the total cost of vessel reduction (4,576 billion won) assumed to be invested equally each year for five years. BCR and NPV with a discount rate (5.5%) were used to compare the profit of fishery activities in offshore and coastal areas. The model results showed that the NPV and BCR in offshore and coastal fisheries was 5,522 billion won and 2.340 respectively.

Objectives: There is no systematic review on economic evaluations of telemedicine in Japan, despite over 1000 trials implemented. Our systematic review aims to examine whether Japan's telemedicine is cost-saving or cost-effective, examine the methodological rigorousness of the economic evaluations, and discuss future studies needed to improve telemedicine's financial sustainability. Methods: We searched five databases, including two Japanese databases, to find peer-reviewed articles published between January 1, 2000 and December 31, 2014 in English and Japanese that performed economic evaluations of Japan's telemedicine programs. The methodological rigorousness of the economic analyses was assessed with a well-established checklist. We calculated the benefit-to-cost ratio (BCR) when a reviewed study reported related data but did not report the BCR. All cost values were adjusted to 2014 US dollars. Results: Among the 17 articles identified, six studies reported on settings connecting physicians for specialist consultations, and eleven studies on settings connecting healthcare providers and patients at home. There are three cost-benefit analyses and three cost-minimization analyses. The remaining studies measured the benefit of telemedicine only, using medical expenditure saved or users' willingness-to-pay. There was substantial diversity in the methodological rigorousness. Studies on teledermatology and teleradiology indicated a favorable level of economic efficiency. Studies on telehomecare gave mixed results. One cost-benefit analysis on telehomecare indicated a low economic efficiency, partly due to public subsidy rules, e.g., a too short budget period. Conclusions: Overall, telemedicine programs in Japan were indicated to have a favorable level of economic efficiency. However, the scarcity of the economic literature indicates the need for further rigorous economic evaluation studies.

폐플라스틱에 대한 국가 간 수출입 제한에 따라, 폐플라스틱의 국내 처리 및 재활용 방안을 모색할 필요성이 커지고 있다. 본 연구에서는 국내 A 기업의 폐필름 발생 현황 및 운영 정보를 참고하여 가구 표면 마감용 sheet 및 edge 제조시 발생하는 PET·OPP 합성 폐필름의 재활용사업에 대한 비용 편익을 분석하였다. 폐플라스틱 처리는 그간 영세업체에 맡겨져 현황 파악이 어렵고 수익성 담보가 되지 않아, 재활용 기술이 있더라도 활용되기에 어려움이 따랐다. 본 연구에서는 폐플라스틱 물질 재활용 방안의 하나로써, 폐필름 발생 사업장에서 PET·OPP 합성 폐필름을 박리하여 폐PET 재활용이 이루어지는 것으로 가정하되, 재활용 비율은 정부가 「전주기 탈 플라스틱 대책」에서 제시한 수치를 활용하여 2%, 10%, 20%, 30% 재활용할 경우 비용편익을 분석하였다. 본 연구에서는 폐PET 재활용 방안으로 물리적 박리 기술이 도입되는 것으로 가정하여 폐PET 재활용 비율에 따른 비용편익분석을 수행하였다. 그 결과 폐PET의 재활용 비율이 30% 이상일 경우에만, 비용 편익비율(Benefit-cost ration, BCR)이 BCR ≥1 에 해당하여 최소비용 편익비율을 충족하는 것으로 나타났으며 이 때, BCR 값은 1.32였다. 향후 정부의 지원금 할당비율과 단가가 상향될 것으로 예상됨에 따라 비용 편익비율은 더욱 높아질 것으로 사료된다. 해당 사례는 유사 업종의 사업장에 폐PET 재활용 및 수익 창출을 위한 시범 Case가 될 것으로 기대된다.

This study investigates to identify the impact factors of timber production cost on the relationship between production cost components and revenues generated by evaluating the entire timber supply chain. In this research, selected 13 logging zones as target areas and classified 14 forest production cost factors, six groups. Additionally, established 13 externalenvironmental factors with related stakeholders and forestry experts. And the BCR (Benefit Cost Ratio) method was then used to analyze the economics of each zone. Filled up a checklist and rated using 5 point scale for each target region, and extracted major cost factors for the production economy of the item. The analysis of major cost factors in the timber production revealed that wood grab equipment usage fee was the first ranked and forest trees purchase cost was ranked in the $2^{nd}$Also, the $3^{rd}$ranking was logging expenses, and transport cost, which accounted for 84% of the total cost, was ranked in the $4^{th}$. In addition, the rock land ratio, slope, timber payment (forest trees purchase cost), special timber, ratio of timber, DBH (Diameter at Breast Height), and mixed forest ratio were the factors that most affected the timber supply chain cost.
