국내 해양레저산업 중 세일요트산업은 현재 초기시장을 형성하고 있으나, 현재 정부의 해양레저 활성화 정책과 해양레저 인구 또한 관련 협회, 클럽 등의 중심으로 급속한 증가세를 이루고 있다. 이에 요트수요 증대에 따라 요트 관련 부품 소재의 경우에도 향후 그 수요가 대폭 증가할 것으로 예상되어지고 있으며, 그 중 요트용 돛(Sail)의 경우에는 전량 해외 수입에 의존하고 있어 제품개발을 통해 국산화함으로써 해외 제품의 수입대체가 요구되고 있다. 본 연구는 해외의 산업용 폴리에스터 원사로 제조된 요트세일 제품의 특성 및 성능 분석 결과와 국산 고강력 폴리에스터 소재로 제조된 요트 세일 개발 제품의 물성 및 성능을 비교 분석하고자 한다. 세일 제품 개발을 위해 해외 요트용 세일 제품을 분석한 결과, 소재는 고상중합형태의 폴리에스터 산업용 원사를 사용하여 직물자체의 고강도 및 저신도 특성발현을 위한 고밀도 제직을 실시한 것으로 분석 되었으며, 가공에서는 해양에서 사용하는 세일 직물의 특성 상 일광 및 자외선에 대한 내구성을 높이고, 황변을 방지할 수 있도록 하기 위해 직물표면에 멜라민계 수지를 이용한 함침방식의 특수코팅을 실시한 것으로 분석되었다. 이러한 해외 요트용 세일 제품의 분석결과를 바탕으로 국산 고강력 폴리에스터 고밀도 직물에 자외선 및 일광에 대한 내구성이 우수한 무황변 타입의 폴리에스터계 수지를 사용하여 단면 코팅으로 양면코팅 가공효과를 부여하는 나이프 방식의 특수코팅, 에이징 처리를 통해 세일을 제조하였다. 본 연구에서는 제조된 세일 직물 제품에 대해, 물리적 특성을 분석하기 위해 인장 강신도, 무게, 두께 및 주사전자현미경 관찰 등의 테스트를 실시하였으며, 세일 성능 분석을 위해 공기투과도, 일광견뢰도 자외선 조사 후 강도변화, 황변 Test 등의 테스트를 실시하여, 해외 선진 제품과 개발제품의 물성 및 성능에 대해 고찰하였다.

I examine the situation in which the players compete to obtain economic rents which is generated by the market-based environmental regulation, such as carbon taxes or tradable permit allocations. Drawing on contest theory, I employ the sharing rules which is devised to motivate players best effort, and consider two models in carbon taxes: one model with observable sharing rules and the other model with unobservable sharing rules. I show that, first, the overall welfare of carbon taxes is always less than that of tradable permit allocations under the model with observable sharing rules. Second, depending on the share of the preassigned allocation in tradable permit allocations, the overall welfare of carbon taxes may be larger than that of tradable permit allocations under the model with unobservable sharing rules.

This research target students who are majoring in sports at junior colleges and it purpose lies in analyzing the differences in the perspectives towards sports related occupations following the individual characteristics of the students. First, when it comes to the difference of the interest in an organization, sophomore shows more difference than freshman and students who are more than 23 years old shows more difference than students who are 21 or 22 years old. Second, when it comes to the difference in economic incomes, sophomore shows more difference than freshman and students who are more than 23 years old shows more difference than students who are 19 or 20 years old. Third, when it comes to the difference in societal status, sophomore shows more difference than freshman. Fourth, when it comes to the difference in the sense of pride towards one's occupation, male students shows more difference than female students, freshman shows more difference than sophomore and students who are more than 23 years old shows more difference than students who are 21 or 22 years old and 19 or 20 years old. Fifth, when it comes to the difference in preference, male students shows more difference than female students. Sixth, when it comes to the rise of social position, there is no difference in sex, school year or age.

How to obtain the financial resources has not been sufficiently addressed, although the unification of Korea incurs enormous cost. This study explains what tax payers of Korea think with regard to the unification tax which is a contradictory issue as a financial resource. The authors analyzed demographic factors, an initial attitude to unification and tax system, and the degree of knowledge as independent variables affecting the intention to pay the unification tax. Furthermore, through the prospect theory, the authors found out how the attitudes of tax payers change by providing them with different messages according to whether they support or oppose the unification tax. The results showed that a group who are male, a group who are old, and a group with high income tend to support the unification and the unification tax more than others. And the results presents that a group who has more interests in both the unification and the unification tax and a group who has more knowledge about the unification and the tax system have more willingness to pay the unification tax than others. In addition, with regard to the persuasive effect of distinct message types, a message which conceals the cost of attitude change was demonstrated to be more effective than a message which emphasizes the benefit.

Miticidal and repellent activity of twenty plant essential oils against the adults of two spotted spider mites, Tetranychus urticae, were examined. Sandal wood oil was the most potent one in mortality, whereas clary sage oil exhibited the greatest repellent activity. On those twenty essential oils tested, no apparent correlation between toxicity and repellency was observed. When the most active oils were blended, the combinations tend to exhibit antagonistic interactions in both toxicity and repellent activity. The chemical compositions of sandal wood oil and clary sage oil were identified via GC/MS analyses, and the major constituents of sandal wood oils were sesquiterpene compounds, whereas the major ones for clary sage oil were monoterpenes. Among the major components in clary sage oil, linalyl acetate was not only the most abundant constituent, but also the most responsible one for its repellent activity.
