This paper attempted to analyze impacts of transition in electricity generation system on a national economy and environmental level in Korea using a recursive computable general equilibrium(CGE) model. In particular, the paper presented a hybrid model combining the top-down CGE model with the bottom-up model which describes the structure of electricity production in detail. The impacts were analyzed by two policy scenarios base on the basic plan for electricity supply and demand proposed by the Korean government. As a result, the paper specifically showed that there exists a trade-off relationship in the policy-making between economic efficiency and environmental level. The paper also suggested that the transition in electricity generation system should be done more gradually and carefully.

The study was conducted to project supply and demand of the physicians from year 1991 to year 2010 based on the analysis of supply and demand of the physicians up to year 1989. Results of the study will provide information for the physicians manpower planning of the 7th 5-year Economic Social Development Planning(1992-1996) and contribute to the overall health manpower planning for the 21the century. It is projected that physician will be oversupplied from the very near future based on the current productivity or underestimated based on the optimal productivity. Thus, it is desirable not to change size of training and education during the 7the 5-year planning period and re-examine the status of the physician manpower at the end of the 7th 5-year period taking into consideration medical services utilization pattern, patients' satisfaction, and physicians' productivity.

The objective of this study is to analyze how much economic impact is changed before and after the designation as biosphere reserve area by tourism. The subject region of this study is Hajun mud village which is the famous place to experience eco-tourism located in Gochang-gun. This region has been designated as a UNESCO biosphere reserve in 2013. In order to estimate the regional economic effects, we employ a regional input-output model which is derived by a RAS method. Using regional input-output model analysis, this study estimates direct and indirect effects of tourist's expenditure on experience of Hajun mud village in Gochang-gun across associated industries between 2011 and 2013. Also, we tried to calculate a net increase in number of visitors in 2013 with considering the trend of tourist in this region and estimate a net regional economic effect after the designation as a biosphere reserve area by tourism. The empirical result could be summarized as follows : (1) the change of production inducement effect shows that regional outputs is approximately increased by 386 million won between 2011 and 2013, (2) regional value-added is increased by 223 million won during the same period, (3) regional employment is approximately increased by 20 according to the labor inducement effects of expanding tourist's expenditure in biosphere reserve area. (4) social service industry has highly been benefited by increase in experience tourist after Gochang-gun was designated as the biosphere reserve area. (5) estimated net increase in number of visitors after the designation as biosphere reserve area is about 37,364 which is 93.4% of the absolute increase in number of visitors amounting 40,011 between 2011 and 2013.

Recent urban sprawl has destroyed various kinds of green space in tile city. It has affected duality of people's life in the city, as well as urban ecosystem. Recent study shows the possibilities of roofs as green spaces in urban central site where the land costs are generally high. This research focuses on Jung-Gu district in Daegu Metropolitan city as a study area and calculates possible area of green roof using 2002 Autocad program based on aerial photographs and land registration maps. And the purpose of this research is to analyze environmental and economic effects of green roof. The environmental effects are as follows. It is expected that $91,106m^2$ green spaces, 12.13 % of study site, will be added if green roof is performed in the study site. It is assumed that the expanded areas could reduce the highest temperature to $0.5-1.0^{\circ}C$ during the summer in terms of environmental effect. And the following shows the economic effects. If green roof and greening urban central site are created as a same size of $91,106m^2$, it will be expected that the costs of green roof will be much more in-expensive than about 98 billions won. It will be also found that the expense of cooling energy can be saved out about 8 millions won per day in summer, if grass planting is accomplished on the possible areas of green roof in the study site. Therefore, it is desirable to take legal supports such as enacting regulations to activate green roof for more environmental and economic effects. For instance, green roof for public institutions, school and model area selection are desirable method to publicize the effect of greening program for citizen's participation.

In order to export Korean spray roses to the China, it is needed to analyse chinese preferences, rose attributes, and purchase intentions. The purpose of this study is to present the implications on the production and distribution of roses for export by analyzing the quality preference attributes and purchase intention of Korean rose for Chinese flower experts. A survey on the preference and purchase intention of Korean flower roses by Chinese flower experts was conducted through face - to - face interviews with flower show participants in China. Approximately 100 Chinese flower experts who participated in the Flower Show in 2016 received the questionnaire, and 86 survey results could be used for analysis. Survey data were analyzed using ordered probit and bivariate probit models. As a result of an analysis, it was found that Chinese flower experts were more likely to buy Korean roses than Chinese roses even if they consider flower color, leaf shape and size and color diversity. The probability of purchasing more than twice the price was higher than that of the color diversity considering the flower shape, leaf shape and size, but the bivariate order probit model was larger than that of flowers, leaves and size, and the order of probability size was changed. In order to increase the export of Korean spray roses to the Chinese market, We need to increase Chinese experts' preferences and satisfaction. For this purpose, it is very important to develop export varieties of roses with large flower buds and shape / coloring, and to apply the useful post-harvest technology that can extend freshness and distribution period of export roses.

바이오플라스틱은 탄소중립적이며 생분해가 가능하다는 점에서 기존 플라스틱의 대체재로 주목받고 있다. 이 연구는 일국 축차동태 연산가능일반균형 모형을 사용하여 석유 기반 플라스틱산업 규제와 바이오플라스틱산업 육성에 따른 경제적 환경적 파급효과를 추정하였다. 분석결과, 플라스틱산업 규제 시 온실가스 감축과 폐기물 감소 효과가 나타나 긍정적인 환경적 파급효과가 발생한 반면, GDP는 감소하여 경제적으로는 부정적인 파급효과를 확인할 수 있었다. 한편 플라스틱산업 규제와 바이오플라스틱산업 육성이 동시에 이루어지는 경우, 플라스틱 산업 규제만 시행하는 시나리오와 비교하여 유사한 수준의 온실가스 감축과 폐기물 감소효과가 발생했으나 바이오플라스틱산업 생산 확대가 기존의 경제적 손실을 상쇄시켜 GDP를 증가시키는 것으로 나타났다. 따라서 바이오플라스틱 생산 확대를 통해 석유 기반 플라스틱을 대체해 나간다면 온실가스 배출 및 플라스틱 폐기물 발생과 같은 환경문제를 개선하면서 경제성장을 가능하게 하는 탈동조화(decoupling)에 기여할 수 있을 것으로 판단한다.

This paper presents an engineering approach to derive the optimum price levels of transacted power. In this paper, with the assumption that power import is possible through the system connection in Northeast Asia regions, the upper price limit of imported power deserving economic efficiency was derived with respect to the time and amount of power import. The proposed approach was demonstrated based on the data from the National Power Development Planning in 2004 with the WASP model.

The purpose of this study was to test system model for family resource management. The data were collected by means of a questionnaire distributed to the sample of 650 wives living in Seoul and Daejeon. The data were analyzed using mean, multiple regression. The result were shown as follows: 1) There were significant differences in three measure of satisfaction ―economic concern, financial satisfaction, general life satisfaction― according to contextual variables, perceived resource adequacy, planning style. 2) Planning style measures provided a unique contribution to the explanation of wives' satisfaction when contextual variables and perceived resource adequacy were controlled, but the degree of contribution was weak.
