The applications of Distributed Generation (DG) in a smart distribution grid environment are widely employed especially for power balancing and supporting demand responses. Using these applications can have both positive and negative impacts on the distribution system. The sizing and location of their installations are the issues that should be taken into consideration to gain the maximum benefit from them when considering the economic aspects. This paper presents an application of the Bat Algorithm (BA) for the optimal sizing and siting of DG in a smart distribution power system in order to maximize the Benefit to Cost Ratio (BCR), subjected to system constraints including real and reactive power generation, line and transformer loading, voltage profile, energy losses, fault level as well as DG operating limits. To demonstrate the effectiveness of the proposed methodology and the impact of considering economic issues on DG placement, a simplify 9-bus radial distribution system of the Provincial Electricity Authority of Thailand (PEA) is selected for the computer simulation to explore the benefit of the optimal DG placement and the performance of the proposed approach.

This research evaluates cooperation in transboundary rivers with special reference to the Great Mekong Subregion (GMS) program in the Mekong River Basin. The benefit sharing approach has been deployed as a theoretical framework to analyze the extent to which the riparian states have achieved cooperation. The river basin governance led by the Mekong River Commission since 1995 has not adequately performed due to non-participation of upstream countries and the lack of law enforcement mechanism. Since the late 1980s, China has undertaken hydropower development unilaterally, thereby triggering discomfort from the Lower Mekong countries. The GMS program has led China to strengthening economic ties with the downstream countries through hydropower development as investors and developers. The program has also supported the establishment of economic corridors, and removal of physical barriers and has paved the way for cooperation in other sectors, such as the environment, agriculture, tourism and energy. There are challenges for further cooperation, including the development gaps between China and the downstream countries, political tensions and environment impacts of hydropower dams in the river basin. The Mekong River Basin shows the possibility of cooperation through benefit sharing. Sharing benefits accrued from the river and beyond the river between China and the downstream countries have enhanced economic ties, thereby consolidating cooperation each another.

Purpose - This study aims to analyzing of solar power generation cost-benefit. Design/methodology/approach - We analyzed whether there is economic feasibility by selecting parking lots and idle sites located in four areas of Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang areas nationwide, and analyzing site conditions and installation capacity. Findings - According to the results of the analysis, it was found that there is low profitability in Seoul, Gyeonggi and Chungcheong regions, where the solar radiation was not excellent even if REC is selected through the contract market. However, it is necessary to analyzed the economical validity the profitable validity including environmental benefits (greenhouse gas reduction, NOx, SOx reduction effect) and social benefits (renewable power supply) that is analyzed by income and operating costs which is occurred from electricity sales and REC sales when installing solar power generation facilities. Research implications or Originality - In this study, economic feasibility was evaluated additionally in consideration of environmental and social benefits. In conclusion, it was shown that businesses are not economical when considering only simple financial aspects are also sufficiently economical when it is considering environmental and social benefits.

The economic feasibility analysis including benefit-cost ratio and internal rate of return of a land consolidation and on-farm development project was mainly depended upon the direct benefits and costs arising during project life. Therefore the projects were neglected in allocating the government's financial funds and loans on account of the low economic rate of return of the project. Accordingly the extended benefit-cost analysis method should be introduced and adapted to cover not only the benefit s such as non-market values of environmental and food security fun ct ions of the project but also market values of the project outputs. The main purposes of this study are (1) to prepare a guide line for economic feasibility analysis based on the IBRD and ADB guidelines, (2) to estimate the benefits from productivity increase, labor saving, savings of O&M cost of farm mechanization and project facilities, savings of farmer's burden for their public health, increasing environmental and public functional value of paddy fields, improving food security condition and formation of peaceful and uncontroversial rural society by implementing the land consolidation and on-farm development, (3) to introduce the newly adapted analytical method as the extended benefit cost analysis which could make possible to be included the values of non-market goods such as the food security and the environmental public function of paddy fields. To carry out this study, the existing publications on the guidelines for economic agricultural projects were reviewed and consultation was made with a For the post evaluation study of the land consolidation and on-farm development project, field survey in Jigok and other comparative area were made to get available information. According to the project completion report, Jigok land consolidation and on-farm development project has 55ha of benefit area out of 69ha of gross area. The project was started in November 11th, 2000 and completed october 30th, 2001. The total project costs were amounted to 2,548 million won and the annual project benefits were estimated at 335million won evaluated by domestic market prices. The ERR(Economic Rate of Return) and SRR(Social Rate of Return) of the project based on the shadow pricing system were estimated at 4.4% and 16% respectively. On the other hand, the ERR and SRR based on the domestic market value system were amounted to 6.37% and 14.62%. In conclusion, Korean land consolidation and on-farm development projects have not carried out from the view point of economic rate of return under shadow pricing system but from the view point of domestic pricing system. For the future feasibility studies on land consolidation projects have to be carried out including the non-market values as environmental and food security function of the projects.

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.

This study empirically analyzes the economic validity of rape farmers. The analysis of economic evaluation is based on the benefit-cost analysis. Previous studies have undoubtedly expanded our understanding of the importance of substitution effects on a rapeseed for bio-fuels. However, earlier studies have mostly dealt with the concept of biodiesel's economics analysis, but this paper's attentions have been paid to the economic analysis of farm. The aim of this paper is suggesting the most appropriate policy brings about why farmhouses should cultivate the rape. To answer this question, this paper adopts a scenario analysis and the B/C ratio is used.
