Objective : Bangpungtongseongsan(BTS) has been used in oriental medicine for many centuries as a prescription for a heat syndrome of apoplexy. The effects of BTS on the vascular system are not well known. This study is designed to identify the effects of BTS on the regional cerebral blood flow(rCBF), arterial blood pressure and action mechanism in mice. Methods : We measured the change of rCBF and BP by BTS. Secondly, we investigated changes of rCBF and BP for 30 minutes interval after venous inject 0.01, 0.1, 1.0, 10.0mg/kg each density BTS infusion into mice, which were premanaged with methylene blue(10mg/kg, i.v), indomethacin(3mg/kg, i.v.), propranolo(3mg/kg, i.v.) for 30minutes. Results : rCBF increased significantly by BTS in a dose-dependent and BP was not affected by BTS in mice. Pretreatment with methylene blue significantly inhibited rCBF increased by BTS and aceelrated BP not affected by BTS. Pretreatment with indomethacin significantly inhibited rCBF increased by BTS and inhibited BP not affected by BTS. Conclusion : These results show that BTS causes the increasement of rCBF and non-change of BP. The action mechanism is related to prostaglandid activated by cyclooxygenase.

Economic systems are the basic concepts or concept clusters which should be emphasized in the economic education. Economic education, practiced in the elementary and secondary level schools, is offered as one realm of the Social studies education. Since the publication of the Process of Education by J. S. Bruner, Social Studies curriculum organizers have tried to seek the structure of social science. Structure is understood to be something which reflect the basic ideas of the related disciplines. This article is aimed to probe the pertinent content materials with respect to economic systems and reflect the structure of the market mechanism. Chapter Ⅱ is intended to present the scheme of the economic systems. In this chapter, the definitions, controversial issues, classifications and performance contrast between economic systems are discussed at large. In the following chapter, to reflect the above mentioned structure, market mechanism is elaborated. The market mechanism, in a word, self-regulating system, is divided logically into four elements. The self-regulating system, Laissez faire, Competitive system, profit motive. Understanding the elements seperately and integrating the elements systematically would lead to the basic ideas of the market mechanism.

In order to apply the Product Liability Law, one’s manufacturer must be identified which is the main agent for compensations. However, under circumstances of fire, most of products are fully burned so it is very hard to specify certain manufacturer and it makes hard for us to apply the Product Liability Law. In this fire case, however, with the victim’s purchase statements and the remote control, the manufacturer approved to apply the Product Liability Law. This case became a starting point of extending the range of applying the Product Liability Law. Also, due to the global warming, there has been an increase of uses in air conditioners. However, the large amount of energy consumption and the expensive electric charges of air conditioners made jet coolers as the alternative. We researched about PCB board by hypothesizing an air jet cooler’s structure and its operation principle as the cause of interior dew condensations, which leads tracking. The purpose of this research is to find out the relation of temperature changes of an air jet cooler and dew condensations while operating. Also, this research is to find out various causes of tracking from the operation of an air jet cooler. And the ultimate purpose of this research is to suggest some ideas related to improvements of an air jet cooler’s structure and the safety standards of electronic products.
