In December 2017, the government announced plans to increase the current proportion of renewable energy from 7% to 20% by 2030 through a plan called the Renewable Energy 3020 Implementation Plan. Therefore, the demand for installation of photovoltaic(PV), wind turbine(WT) and battery energy storage system(BESS) is expected to increase. In particular, the system combined with energy storage system(ESS) is expected to take up a large portion since PV and WT can receive high renewable energy certificates(REC) weights when combined with ESS. In this study, we calculate the optimal capacity of the power conditioning system(PCS) and the BESS by comparing the economical efficiency and maximize the efficiency of the PV-BESS system in which the PV and the BESS are connected. By analyzing the system marginal price(SMP) and REC, it maximize profits through application of REC weight 5.0 and optimal charge-discharge scheduling according to the SMP changes.

Korea is undergoing a rapid environmental change in health and welfare. Therefore, the law mandates the establishment and implementation of plans in accordance with the changes. A total of 49 long-term plans related to health and welfare were specified by the National Law Information Center, the Korean representative legal information website managed by the Korea Ministry of Government Legislation. Of the 49 long-term plans, 10 plans (20.4%) were not yet fully constructed. Eight out of 10 non-constructive plans have been put into force for more than a year, but these plans still require further systematic planning and development. The complete construction of long-term plans is substantial to account for the changes in South Korean health and welfare. In addition, a systematic plan with solidarity and continuity between the mutual plans should be established in planning.

Through 'The Renewable Energy 3020 Implementation Plan' for carbon neutrality, the government promised to raise the proportion of renewable energy generation to 20% and renewable energy installation capacity to 63.8% by 2030. Therefore, we plan to test a 5.5 MW offshore wind turbine near Maldo, Gunsan. In this project, we measure the level of public acceptance and perform ordinary least squares (OLS) regression analysis to show the determinants of public acceptance. The regression results are as followed. First, it is judged that the closer the distance to the offshore wind turbine, the more the economic effects considered by residents. Second, especially in Maldo, the experience of being discriminated from the Saemangeum project, is understood to have caused distrust in the surrounding fishing villages chief/Fisheries Cooperatives, converted into a local community effect. Finally, the policy implications are as follows. First, a bottom-up problem-solving method is required to improve public acceptance, based on the Living Lab. Second, the island community may be indifferent to the briefings or forums of outsiders. Therefore, a gradual approach is required through (in)formal channels based on reliability from a long-term perspective with nearby universities and research institutes using SamsØ Energy Academy.

Production management in the automobile parts industry is carried out according to the production plan of the customer, so it is important to prevent shortages in product supply. As the product composition became increasingly complex, the MES System was built for the purpose of efficient production plan management and inventory management, but its utilization is low. This study analyzed the problems of the MES system and sought to improve it. Through previous studies, it was confirmed that the inventory management of the pull approach that actually occurred in the warehouse is more suitable than the push approach based on the forecast of the warehouse for the volatility, complexity, and uncertainty of orders in the auto parts industry. To realize this, we tried distributed MRP by using the ADO function of VBA to link the standard information of the MES system with Excel and change the structure of the BOM table. Through this, it can help increase the accuracy of production planning and realize efficient inventory management, thereby increasing the utilization of the MES system in the auto parts industry and enhancing the competitiveness of the company.

Recently changes in the technological environment of marine transportation and the increase of traffic volume have fostered a revolution in the design and operation of port and also playing a major role in the development of new types of port in Asian. These changes are dynamic and will continue to influence port physical distribution system. The port of Pusan has been hardly able to handle the traffic increases in recent years by expansion increased mechanization and other operational and institutional improvements but, further traffic increases bring about critical congestion and such congestion is an economic cost to the country in terms of cost of physical distribution. This paper treats the development of entirely new port of Pusan and related transportation system by considering the existing or expected need for improved port capacity and services. The western part of GADUK island is selected as the optimum port site through the detailed analysis of the physical requirement and careful consideration of regional development and since the lead time of the national development plan including the port project from initial planning to implementation is considered as long as 7 to 10 years the aggregated master plan for port development is made and implemented in the year of 2012.

Objectives: One of the main objectives of the Targeted Subsidies Law (TSL) in Iran was to improve equity in healthcare financing. This study aimed at measuring the effects of the TSL, which was implemented in Iran in 2010, on equity in healthcare financing. Methods: Segmented regression analysis was applied to assess the effects of TSL implementation on the Gini and Kakwani indices of outcome variables in Iranian households. Data for the years 1977-2014 were retrieved from formal databases. Changes in the levels and trends of the outcome variables before and after TSL implementation were assessed using Stata version 13. Results: In the 33 years before the implementation of the TSL, the Gini index decreased from 0.401 to 0.381. The Gini index and its intercept significantly decreased to 0.362 (p<0.001) 5 years after the implementation of the TSL. There was no statistically significant change in the gross domestic product or inflation rate after TSL implementation. The Kakwani index significantly increased from -0.020 to 0.007 (p<0.001) before the implementation of the TSL, while we observed no statistically significant change (p=0.81) in the Kakwani index after TSL implementation. Conclusions: The TSL reform, which was introduced as part of an economic development plan in Iran in 2010, led to a significant reduction in households' income inequality. However, the TSL did not significantly affect equity in healthcare financing. Hence, while measuring the long-term impact of TSL is paramount, healthcare decision-makers need to consider the efficacy of the TSL in order to develop plans for achieving the desired equity in healthcare financing.

본 연구는 과거 이명박 정부 기간 중 국민의 사회안전 인식 변화를 고찰하고 이를 토대로 박근혜 정부 출범에 따른 사회안전 관련 국정운영 발전방안을 제시하는데 그 목적이 있다. 이와 같은 목적을 달성하기 위하여 2008년부터 2012년까지 국민의 사회안전 인식 변화를 분석하고 이에 근거한 박근혜 정부의 사회안전 정책추진 발전방안을 도출하였다. 이와 같은 연구목적과 연구방법을 통하여 도출한 연구결과는 다음과 같다. 첫째, 포괄적인 사회안전 관련정책의 지속 추진이 필요하다. 사회안전이 국민의 생명과 직결되고 실생활에 밀접한 관계가 있다는 점에서 사회안전 주요요인에 대해 어느 하나 소홀히 하거나 간과할 수 없는 실정이다. 따라서 사회안전 주요요인에 대한 포괄적인 국정운영 및 정책추진이 필요하다. 둘째, 국민이 체감할 수 있는 사회안전정책 강화가 요구된다. 범죄 발생의 경우는 국민의 57.1%가 사회불안요인으로 지적할 만큼 그 비중이 높으므로 이에 대한 국가적 관심을 집중함으로써 대(對)국민 신뢰도 제고를 도모하고, 안보에 있어서도 철저한 국방대비태세로 이에 대한 우려를 불식시킬 수 있어야 할 것이다. 셋째, 사회안전 관련부처의 체계적인 조직 운영 및 상호 협력이 필요하다. 제반 사회안전을 체계적으로 관리하기 위해서는 안전행정부, 국방부, 검찰청, 경찰청 등 대표적인 공안기관뿐만 아니라, 정부기구 대부분이 참여하는 체계적인 국정운영이 필요하다. 넷째, 일관성 있는 사회안전 정책 추진이 요구된다. 박근혜 정부가 '안전과 통합의 사회', '행복한 통일시대의 기반 구축' 등을 국정목표로 설정하고 있으나 이는 역대 정부의 사회안전 정책과 유사하므로 과거 정부와 차별화를 기하기보다는 일관성 있는 사회안전 관련정책 추진이 더욱 중요하다.
