This study tries to find the policy instruments that have used in the process of social insurance policy implementation. The results can be summarized as follows: First, in case of compulsory policy instrument, the government uses the regulation, public enterprise and government insurance in the process of implementing of all the social insurance policy. Second, in the case of mixed policy instrument, the government use the user' contribution in the process of implementing of all the social insurance policy but the subsidy was used in the process of implementing of the medical, pension, unemployment and long-term care insurance for the aged policy. Also, the information and discipline was used in the process of implementing of unemployment insurance policy and the partnership was used in the process of implementing of long-term care insurance for the aged policy. Third, in case of voluntary policy instrument, the government uses the family and community in the process of implementing of almost the whole social insurance policy.

This paper analyzes the economic and environmental impacts of domestic policy to reduce greenhouse gas emissions by focusing on carbon tax, domestic emissions trading and the mixture of these policies. By utilizing a dynamic CGE model, KORTEM, this study shows that the economic cost under carbon tax is projected to be higher than that under emission trading. It is because under carbon tax scheme each emitter in economy must meet its emission target regardless of the abatement cost. On the other hand, emission trading allows emitters to reduce the marginal cost of abatement through trading of emission permits. In designing policy portfolio to address the climate change problem in Korea, therefore, this paper proposes the introduction of domestic emission trading scheme as the main domestic policy Instrument.

국가 에너지원의 다원화와 환경공해 저감은 정부의 저탄소 녹색성장 정책과 에너지 안보를 위해 달성해야만 하는 필수불가결한 과제로 자리 매김한지 오래이다. 또한, 화석연료의 환경문제 유발과 석유자원의 고갈위기 등으로 인해 이를 대체할 수 있는 신재생에너지 개발에 대한 관심이 고조되고 있으며 이러한 과제를 해결하기 위한 친환경 연료로써 DME(Dimethyl ether)에 대한 관심이 날로 증가하고 있는 추세이다. 특히 높은 세탄가를 지니고 물성이 LPG와 유사하여 디젤차량 및 LPG 대체 연료, 연료전지 등의 다양한 용도로 사용할 수 있고 수송 저장 수단, 인프라 구축 등의 장애가 적다는 장점이 있으며, LPG와 물리적 특성이 비슷해 기존 LPG 인프라를 개조하지 않고도 LPG와 혼합해 난방 및 취사뿐 아니라 차량 연료용으로도 시범사업이 활발히 추진되고 있는 상황이다. 그밖에도 액화상태로 저장 운송 등의 취급이 용이하다는 장점이 있다. 한국가스공사의 경제성 분석 결과, 본격 보급시 LPG대비 20~30% 저렴하게 공급가능하다고 판단되어짐에 따라 LPG사용자 부담을 완화할 수 있는 기대를 가지게 한다. 이에 우리협회는 지경부 한국가스공사등과 함께 프로판에 DME가 20%의 혼합된 DME혼합연료 소비자에게 보급하는 시범사업을 전개하고 있으며 현재까지 진행된 내용과 향후 계획등을 소개함으로써 DME에 대한 이해를 높이고자 한다.

The Purpose of this study is to present effective Anti-Drone systems to protect national important facilities against drones that are illegally used by crime groups and terrorists with malicious intents. In order to accomplish the purpose of the study, technical and policy reports regarding Anti-Drone systems, open documents from manufacturers and various research papers are reviewed, and in-depth interviews with experts were conducted. Studies have shown that it is effective to overlay and mix different detection systems so that they can improve detection rates by supplementing each other's advantages and disadvantages, and that the means of incapacitation need to acquire flexibility by using both soft-kill and hard-kill methods in accordance with operational environment for the effective usage. In other words, the establishment of an illegal drone pre-management system, mixed and overlapping detection assets, determining appropriate countermeasures, and multiple distribution of means of incapacitation. The establishment of a protection system for important national facilities through the operation of overlapping and complex anti-drone systems is the most urgent task.

This study examines and identified a series of strategies of Russia's political elites to maintain and strengthen their dominance by reviewing the case of revisions in the election laws of Russia in 2014. At that time, a mixed-member electoral system was newly introduced, and on the surface, it seemed that the new system was a step toward meeting the demands of the people for "enhanced democracy". However, in 2016 and 2021, the ruling party of Russia won the general elections by making the most of the factors that could distort the election results inherent in the mixed-member electoral system. Therefore, this study aimed to analyze whether the revision of election laws was a mere vehicle used by the ruling party, United Russia, to maintain its political power, or whether it was a leap forward to achieve democracy. The study result indicate that the revision of election laws in 2014 was part of the policy responses to the internal conflicts in the circle of Russia's political elites, which had been rising since 2008, as well as to the public resistance. In other words, it was confirmed that the revision of election laws was one of the measures taken to "minimize competition" and "reproduce political power on a stable basis".

This paper discusses the European Union's smart specialization strategy and US manufacturing renaissance policy and then proposes new directions for regional industrial policy in Korea. The smart specialization strategy is summarized as the entrepreneurial self-discovery and strategic coordination; the manufacturing renaissance policy as the construction of industrial commons based on ecosystem; and Korea's regional industrial policy as the build-up of regional innovation system based upon industrial clusters. The policy cases of the EU and the United States demonstrate the fact that regional industrial policy should be geographically embedded. Also, they show the relevance of policy mix by linking industrial policy with innovation policy for cross-fertilization between different industry and technology. In addition, the state plays a role as a coordinator and mediator by embedding the democratic discipline into industrial ecosystems. Considering these points, regional industrial policy should be transformed into a platform system that can facilitate linkage between industry and technology.

The existence of rebound effect from road extension in Korea has been quantitatively verified using cross-sectional, time series data on four major cities - Seoul, Busan, Daegue and Incheon - between 2000 and 2013. The linear mixed effects model was constructed from six variables: total vehicle miles traveled (VMT), road extension, public transport users, gross regional domestic product (GRDP), regional population and fuel consumption. The main results can be summarized as VMT is positively correlated to road extension while negatively with public transport users. It indicates that the road extension-centered "supply-side" transportation policy induces "additional travel" and create "generated traffic" by enhancing driving efficiencies directly, or degrading other transport modes indirectly. Hence, the ultimate goal of road congestion reduction requires public transport-centered "demand management" rather than current supply-side policies.

Recently, there has been a debate as to whether bioethanol should replace some portion of gasoline for fuels in South Korea, as energy security as well as climate change issues are rising as a significant national agenda. However, a considerable amount of subsidy will be required to compensate for the higher price of bioethanol-blended gasoline. In this context, government subsidy will obtain justification only when the positive social gains from consuming bioethanol for fuels can exceed the negative social costs. Through a nation-wide choice experimental survey, we examine if South Koreans have a positive value as well as non-linear preferences on substituting bioethanol for gasoline. The results reveal that the willingness to pay for purely domestic bioethanol-blended gasoline within 10% is about 52 KRW; Koreans have concave preferences on the blending ratio of bioethanol to gasoline. The turning point of the blending ratio of bioethanol was 6.5%. Also, we found inverse U-shaped curve between income and bioethanol choice probability and the turning point of the income was calculated as 250~299million KRW. Politically conservative propensity advocates uses of bioethanol blended gasoline, but awareness on bioethanol or more weights on environmental conservation have significantly negative effects on the choice of bioethanol. However, the design of the survey questionnaire is incompatible with the RFS of Korea and assumes orthogonality among the following four interrelated attributes: (i) domestic or offshore procurement of feedstocks in the case of domestic production, (ii) domestic production or import of bioethanol, (iii) the blending ratios, and (iv) the retail price increases. In addition, the results of model estimation and of model selection test are not definite. Hence, the results in this study should not be directly applied to the design of the specifics of the Korean RFS. Hence, the results in this study require cautions in applying to the design of the Korean RFS policy.

It is important to empirically investigate the typological characteristics of subway station areas considering the comprehensive elements of transit-oriented development (TOD) planning so that its implementation can be effective in attaining both increase in transit ridership and decrease in inordinate automobile dependence. This article aims to identify diverse features of subway station areas in Seoul known for good public transit system. After collecting and manipulating the measures on planning elements such as density, diversity and accessibility for TOD planning by distance-based buffer from a subway station, the article tried to interpret analysis results on their typological characteristics. They can be summarized with two conclusions. First, characteristics of landuse and public transit system can be distinctly differentiated in the Seoul subway station areas. It implies that both planning elements should have not been integrated for now. Second, the characteristics of public transit system can be divided by modes. They provide us that public transit system in Seoul needs to be more strongly integrated than current system.

Many soil amendments have been used nowadays to improve physical and chmical condition of turf soil, which might ultimately optimize turfgrass growth in golf courses. This study was carried out to Investigate the effects of new organic soil amendment containing pig excreta 50% and sawdust 50% on growth of zoysiagrass (Zoysia japonica L.) and kentucky bluegrass (Poa pratensis L.) in greenhouse. Three applicable treatments with soil mixtures of 10, 20, and 30% (v/v) animal organic soil amendment (AOSA) with sand, were tested for chemical property, physical property, visual quality and root length of zoysiagrass and Kentucky bluegrass. As results, application of $10{\sim}30%$ AOSA mixtures were proper to grow turfgrass in soil nutrition. Especially, the treatment with 20% AOSA mixtures showed 0.7% in organic matter, which meets to green standard of USGA. Also, 30% AOSA mixtures was 1.1% in organic matter, which might be desirable for zoysiagrass-planted golf courses in Korea. It was turned out that addition of AOSA decreased the hydraulic conductivity in soil physical property Because the sand possess high hydraulic conductivity, it is recommended to combine $10{\sim}30%$ AOSA with sand in order to sustain soil balance. The treatment with $10{\sim}30%$ AOSA noticeably increased visual quality of both zoysiagras and Kentucky bluegrass during 90 days. However, treatments with either 20% or 30% AOSA were effective to develop root length of zoysiagrass but treatments with 20% AOSA were more effective than that of 30% AOSA mixtures to promote root length of Kentucky bluegrass at 60 days. In conclusion, considering all vital factors such as visible quality, root growth, organic matter content, and economical efficiency, was taken, it is recommended that a $20{\sim}30%$ mixture of AOSA with sand is good for the growth of zoysiagrass and 20% mixture for Kentucky bluegrass.
