The aim of this study is to evaluate the economic feasibility of domestic on-site steam methane reforming (SMR) hydrogen refueling stations. We evaluated the levelized cost of hydrogen (LCOH) for the SMR hydrogen refueling stations, which have production capacities of 100 kg/day (SMR 100), 200 kg/day (SMR 200), and 500 kg/day (SMR 500) utilizing the scale factor. The main results indicated that the LCOH of SMR 100, SMR 200, and SMR 500 were 14,367 won/kg, 11,122 won/kg, and 8,157 won/kg, if the utilizations of hydrogen stations were 70%. These results imply that the production capacity of the domestic SMR hydrogen station should be greater than 500 kg/day to compete with other hydrogen stations when we consider the current sale price of hydrogen at the hydrogen stations.

This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.

이 연구의 목적은 경제공간의 역동성을 이끄는 세계화, 지식기반경제, 정보사회, 서비스세계의 4대 글로벌 메가트랜드를 통해 국가간 및 지역간에 나타나는 공간경제의 불균형을 이해하는 것이다. 동아시아를 대상으로 국가간 불균형과 일본, 한국, 태국을 사례 로 국가 내에서 지역간 불균형을 분석하였다. 4대 메가트랜드와 관련된 변수들을 모두 고려할 때, 4대 글로벌 메가트랜드는 국제적인 차원과 국가내의 지역적인 차원에서 불균형의 변이를 설명해주고 있다. 그러나 개별변수들이 공간적 불균형에 미치는 영향은 분석의 공간적 규모와 국가적 특성에 따라 달리 나타난다. 대체로 동아시아국가들간에 1인당 GNI는 수렴하는 경향을 보이고, 한 국가내의 지역차원에서는 불균형이 줄어드는 경향과 확대하는 경향이 함께 나타나고 있다. 1970년대의 두 차례의 석유파동과 1990년대 말경의 동아시아 금융위기는 일반적인 불균형완화경향의 연속성을 단절시키는 결과를 초래했고, 경제활동의 지역간 국제간 불균형을 증가시켰다. 이는 세계적인 위기의 영향이 국가에 따라 다르지만 일반적으로 주변국가와 주변지역의 경제는 세계적 경제위기상황에서 더욱 취약하다는 점을 시사한다.

In this study, factor and cluster analysis have been conducted to group the differences in Korean view on national economic policy in the sample of the 2006 Korean General Social Survey (KGSS). According to the 2006 KGSS, the 6 items with a 5-point Likert scale include the questions about whether or the extent to which each respondent supports the specific types of governmental economic policy. In our study, at first, the factor analysis has converted the original 6 items into the 3 composite variables that account for 81% in the total variability. As the second step of factor analysis, factor scores have been computed. Then, the K-means cluster analysis based on the factor scores has been conducted to group the survey respondents into the 3 clusters. In particular, the cross-tabulation analysis has shown that the distribution of the 3 clusters varies with the respondents' socio-demographic characteristics.

This study analyzes the factors affecting farmers' recognition and acceptance of sustainable agriculture. To accomplish the objectives of the study a farm survey was conducted using target respondents which were made of the local correspondents and reporters of Korea Rural Economic Institute. The Heckman's model was employed for an empirical analysis on determining the extent of farmers' acceptance of sustainable agriculture. The analysis results show that the more farmers think it is important for Korea to adopt sustainable farming practices, the more they adopt sustainable agriculture. It is also shown that the high incomes farmers earn, the more interest they have in the environment and thus the more likely they are to adopt sustainable agriculture. Based upon the empirical results it is suggested that an adoption of economic incentive instruments, education of sustainable agriculture, research and development of sustainable agriculture technology, and an establishment of sustainable agriculture infrastructure to expand the scale of sustainable agriculture.

This study investigated structural changes of the Korea's agriculture and proposed the new direction of rural and agricultural policy in Korea after economic opening. The major results may be summarized as follows: Firstly, the study identified structural changes of the country's peasantry under the economic opening system. Korean agriculture has been deteriorated in population structure, arable land size, and income composition. Secondly, according to above analysis on these changes it suggested that the traditional rural communities were exposed to collapse and this unwanted disaster could result in serious adversities to the national economy. Thirdly, this study proposed preservation policies for small scale farming households and also administrative preparations of multi-dimensional approaches leading to successful rural and agricultural planning.

The economic development system of Korea is based on export-oriented strategy and the free trade agreement. So Korea is trying to conclude the free trade agreement with China, Japan, and EU. The reason is that Korea will have more chances to develop there economy scale and trade surplus, but it will give the worst economic situation. The research showed that the effects of FTA on Korea's GDP will be much greater than China's and Korea's trade surplus with China will expand in the manufacturing sector, but agricultural and marine products are layed in opposite situation. Especially comparing with other Provincial, Gwangju Jeonnam has a relative importance portion of agricultural and marine products. So, Gwangju Jeonnam have to prepare the effects of agricultural and marine products under the Korea China FTA.

The advent of Electronic Commerce is raising two hypothetical questions conflicting each other in economic point of view. The one is that cyberspace will eventually resolve the problem of economic disparity by presenting equal opportunities to local companies through the removal of barriers in terms of time and space. The other is that the problem of economic disparity will be amplified by the vicious cycle of reproduction on an enlarged scale residing in the new rules of digital economy. As an initial attempt to tackle the questions listed above, by introducing systems thinking and adopting the systems dynamics simulation technique this paper puts an effort to find some tentative answers to the questions possibly raised about the impact of electronic commerce on local economy on which little research has been conducted so far. The general scheme for the dynamism of systems where two groups of electronic malls compete each other and the findings presented in the paper would perhaps provide some ideas and directions for further study.
