The purpose of this paper is to perform empirical studies on the impact of pollution intensity on international competitiveness using 1993 and 1998 data, and to estimate the change in environmental regulation level faced by the firms during 1993~1998. Collecting relevant data and providing them for further studies in the area are another purposes of the paper. The first method is the regression of various indices of international competitiveness on factor costs, such as labor, capital, R&D and pollution abatement costs. Goal of the regression analysis is to estimate the scarcity and comparative advantage effect of each production factor, especially environmental resource. Regression results show that those industries which employ more environmental resource have higher comparative advantage in both years, which implies that Korean firms are endowed with abundant environmental resource compared to other countries. The second method is to compute the relative scarcity indices(HOVL indices) of production factors, proposed by Leamer based on Vanek's generalized Hecksher-Ohlin Theorem. This method estimates the relative scarcity of production factors by computing factor costs embodied in import and export of commodities. This method shows similar results as the regression method; i.e., trade pattern of production factors implies that the manufacturing sector in Korea is endowed with abundant environmental resource compared to other countries. Considering population density, water resource endowment, intensity of economic activity per unit area and current air and water pollution levels, it is evident that Korea is never endowed with abundant environmental resource compared to other countries. Then the abundance of environmental resource revealed by the trade patterns of commodities and production factors implies that Korea's environmental regulation level is excessively generous compared to environmental capacity, and that this increased the environmental resource endowment supplied to firms and thus distorted the inter-industry comparative advantages. Both regression and HOVL methods, on the other hand, show that overall environmental regulation level faced by the firms has been strengthened during 1993~1998.

This study examined the influence of social responsibility awareness (economic and social-environmental responsibility) and trust in corporate social responsibility on sustainable diets. The subjects of the study were 468 university students. The main research results were as follows. First, the social responsibility awareness of the study subjects was 4.03±0.72 points for economic responsibility and 3.48±0.81 points for social-environmental responsibility. An awareness of economic responsibility showed differences according to gender. Trust in corporate social responsibility was 3.62±0.61 points, and there was no statistical significance based on gender. Second, the level of a sustainable diet was food safety and consideration (4.06±0.63), knowledge of the environment and diet (3.94±0.68), understanding of the food circulation system (3.45±0.77), and healthy diet (3.26±0.89). Among the factors influencing a sustainable diet, female students had higher attitudes toward food safety and consideration and understanding of the food circulation system than male students. Third, the social responsibility awareness (economic responsibility and social-environmental responsibility) and corporate social responsibility trust variables influenced university students' sustainable diet. Among these, social-environmental responsibility awareness had the highest influence.

In addition to simply providing quality food to the people, the fishery industry must be maintained and developed because it has various functions such as national food security, preservation of natural scenery, protection of national territory, and revitalization of the local economy. However, risk factors such as climate changes and environmental destruction have raised concerns about the sustainable development of the industry. Since these risk factors are becoming larger and more complex over time, it is time to conduct research related to the risk of the fishery industry. Therefore, the purpose of this study is to explore the risk factors facing the fisheries at this point, to analyze the economic ripple effect of regional fishery product supply shortage, and to draw implications. As a result of this study, the economic ripple effect of fishery product shortage per won was highest in Busan, followed by Gangwon, Gyeongnam, and Gyeongbuk. Considering the size of the local fishery industry, Busan had the highest supply shortage per 1% of local fisheries production. It is also necessary to prepare special risk management and countermeasures for these regions since the effect of supply shortage in regions such as Jeonnam, Gyeongnam, and Jeju is large compared to other regions.

In this paper, we design a green supply chain (gSC) network model. For constructing the gSC network model, environmental and economic factors are taken into consideration in it. Environmental factor is to minimize the $CO_2$ emission amount emitted when transporting products or materials between each stage. For economic factor, the total cost which is composed of total transportation cost, total handling cost and total fixed cost is minimized. To minimize the environmental and economic factors simultaneously, a mathematical formulation is proposed and it is implemented in a genetic algorithm (GA) approach. In numerical experiment, some scales of the gSC network model is presented and its performance is analyzed using the GA approach. Finally, the efficiencies of the gSC network model and the GA approach are proved.

This study attempted to investigate the factors influencing alcohol drinking habit of college students in Korea. To find how many students are alcohol dependents and what factors are related to problem drinking habit, the current study estimated problem drinkers and analyzed the relationship of problem drinking and various factors. In 2000, 736 students reported the questionnaires. Estimated rates of problem drinkers standardized by age were 0.7% of male and 0.5% of female students by NAST, amounting 9,300 college students. Age of initiation of alcohol drinking, alcohol or drug use problems of parents or mends, psychological factors, emotional factors, and two of MMPI scales were significantly different between moderate drinkers and alcohol dependents. The moderate and problem drinkers were significantly different in Mf and Pa average scores. However, economic factors were not significantly different between the moderate drinkers and alcohol dependents. Based on the results, this study suggested that further multivariate studies with large sample need be conducted to investigate the relationship between alcohol dependency and its factors.

Rail transport has been considered as an environmental-friendly transport mode compared with other transport modes such as ship, truck, and aircraft. However, rail industry can not avoid a duty of alleviating Greenhouse gases emission owing to the Korean government polices for green growth which is an economic paradigm that simultaneously pursues growth and environmental improvement. The purpose of this research is to develop a methodology of determining an economic speed of freight train to be green freight train by considering fuel cost, environmental cost, and time cost. In the methodology, we first define a cost function based on cost factors and then suggest an economic speed of freight train by deriving a property.

This study is aimed at the deduction of the important priority factors by setting the comprehensive rate in each of the economy, sociability and environmental areas for the sustainable development of fishing villages. As the research methods, review of domestic and overseas literature and Delphi questionnaire survey on experts, and hierarchical structure analysis were executed. Accordingly, this study is aimed at providing the basic data at the time of establishing plans by assessing the level of importance and priorities for each item through the deduction of the elements necessary for the fishing village plan. Key results of the study are as follows. First, as the results of review of domestic and overseas literature related to sustainability indices of fishing villages, a total of 50 items in the areas of economy, sociability and environment were deduced. Second, validity for each area was confirmed through Delphi questionnaire survey on experts. Third, as the results of factor analysis conducted on the basis of the hierarchical structure analysis for detailed items for each sector, 3 factors in the economic area, 2 factors in the social area and 3 factors in environment area were deduced. Fourth, as the results of the relative importance of the higher tiers, economic sector (0.528) displayed results that are more than 2 times higher than the social (0.261) and environmental (0.212) sectors. Establishment of foundation for independent competition (0.105), balanced development of small fishing village (0.086) and population engaged in economic activities in comparison to the fishing village population (0.077) were analyzed as the most important detailed items. Based on these results, experts pointed out that the economic sector is most important for the sustainable development of fishing village and, in detail, priority must be placed on the balanced development on the basis if the extent of independence of the fishing villages, and emphasized activation of residents engaged in economic activities in fishing villages in order to support them. That is, in order to increase the level of independence of the fishing villages, it was determined that there is a dire needs for expansion of diversified specialized businesses and infrastructural facilities through agreement by the residents capable of economic activities, and means of activating fishing villages through securing of budget at the local autonomous government level to provide support for the residents.

This paper is aimed to analyze the determinants and their relative importance that affect regional competitiveness in the era of globalization and climate change. The panel model was set by a balanced panel data for 7 metropolitan areas & 9 provinces and for the period of 2001~2010. Gross regional income per capita is used as the dependent variable and competitiveness-based factors, economic production factors, and climate change adaptation factors are selected as the explanatory variables. In this study, Model 1(typical regional competitiveness model) and Model 2 (added adaptation to climate change adaptation factors) were compared. The important findings can be summarized as follows. The most influential determinants on regional competitiveness are the ratio of knowledge-based industries and human capital and energy inefficiencies decrease the regional competitiveness. Compared to Model 1, Model 2 showed that the effects of the regional openness and the technology innovation capital are relatively more influential in Model 2. The results of this empirical study provide policy implications to strengthen the regional competitiveness in the future of the era of globalization and climate change.

In this study, Ichon basin is selected as study area and regional analysis of geological structure are done by using lineament analysis. The factors which affects slope stability, are chosen, and integrated to database using GIS (Geoscientific Information System). Landsat TM band 4, 5 and 7 are choosen and processed by various image enhancement technique to analyse the regional geological lineaments. Spatial distribution of lineament is analysed through lineament density map and study area can be divided the eight structural domains. Considering environmental geological characteristics of study area, rating and weighting of each factors for slope stability analysis are determined and spatial analysis of regional slope stability is examined through overlaying technique of GIS. The result of areal distribution of slope stability shows that the most unstable area is all over Mt. Buksung, Mt. Daepo, Mt. Songrim and Mt. Yankak.

Regional evaluations of slope stability by the failure criterion and by environmental geological factors were conducted. The failure criterion is the general conditions for plane failure which consider the geometrical conditions between geological discontinuities and topographical slope planes. The factor focused in this condiction is dip and dip direction. Geostatics, named semivariogram was used for establishing structural domains in slope stability evaluation by the failure criterion. The influential range was calculated to 6 km in the case of dip direction of dominant joint set and 7 km in the case of dip of the same dominant joint set. Then applying this failure criterion to the study area produced a slope stability map using the established domains and slopes generated by TIN module of ARC/INFO GIS. This study considered another regional slope stability analysis. 5 failure-driven factors 9the unstable slope map, geology, engineering soil, groundwater, and lineament density) were selected and used as data coverages for regional slope stability evaluation by geoenvironmental factors. These factors were weighted and overlayed in GIS. From the graph of cumulatave area (%) and instability index, finding critical points classified the instability indices. The most unstable slopes are located in the southern area of Mt. Eorae, Dabul-ri, and the eastern area of Junkok-ri in the first area is plane failure. Also, the expected orientations of failure are 59/338 and 86/090 (dip/dip direction).
