Impatience characteristics are an important factor to be considered in the defense field, which is sensitive to time, but there are not many cases applied. In addition, due to the difficulty of analysis that must consider various probabilistic factors (breakdown/maintenance distribution, impatience characteristics, etc.), military decision makers consider only simple data (number of occurrences per year, maintenance time, etc.) Therefore, in this study, a model capable of analyzing the performance of the emergency maintenance system for determining the appropriate size and organization of military and civilian maintenance personnel was presented in consideration of impatience characteristics and probabilistic factors. And through numerical analysis, the appropriate size of the military and civilian emergency maintenance teams was analyzed. This study is significant in that it can improve readiness of operational power and prevent waste of defense budget through efficient operation of the military's emergency maintenance system.

This paper explores antecedents of entrepreneurial and job search intentions based on the theory of planned behavior. Additionally, it examines the impact of entrepreneurship and job search education on these antecedents of entrepreneurial and job search intentions. The research model has been validated by analyzing 1,432 responses from undergraduate students in South Korea. The results of analysis provide several findings: First, entrepreneurship attitude, entrepreneurship subjective norm, and entrepreneurship self efficacy showed significant positive effects on entrepreneurial intention, but their effects on job search intention were insignificant. Second, while job search attitude showed significant positive effects on both intentions, job search subjective norm showed a significant effect only on job search intention, and job search self efficacy showed a significant effect only on entrepreneurial intention. Third, entrepreneurship education increased all the antecedents of entrepreneurial intention, and reduced job search attitude. These results imply that entrepreneurship and job search education should be managed comprehensively, considering their cross-effects on the antecedents of entrepreneurial and job search intentions.

Eco-driving is the best of the ways to reduce fuel consumption as a driver"s effort because it has the merit that don"t need a initial facilities cost. So, many countries have been developing the ways of eco-drivng and conducting the campaign to promote eco-driving to their own citizen. In this paper, the fuel economy and the emission was measured to verify the effects reducing the blower strength of an air conditioner and a heater(HVAC) of a vehicle. The result showed that the way can decrease the rate of increase of fuel consumption and some emission caused by using HVAC.
