COO(원산지 효과)에 대한 많은 기존의 연구들이 이루어졌음에도 불구하고, 대부분의 기존의 연구들은 주로 전자제품 등의 공산품을 중심으로 또한 선진국-고품질 제품, 개발도상국 - 저품질 제품의 틀 속에서 연구가 주로 이루어져 왔다. 또한, COO를 통한 전반적인 마케팅 전략의 수립보다는 마케팅 프로세스의 일부분에 COO가 미치는 영향을 연구한 단편적인 연구가 대부분이었다. 이에 본 연구에서는 기존 연구와는 달리 선진국인 미국과 일본 시장을 대상으로 한국의 고품질 농산품인 “고려인삼”의 마케팅 전략의 수립이라는 전체적 측면에서 COO에 대한 기존 이론들을 검토하고 이를 실증하였다. 연구의 결과 고려인삼은 미국과 일본시장 모두에서 원산지 효과가 있는 것으로 나타났다. 하지만, 시장 세분화를 위한 가설인 고연령 - 저학력의 사람들에게 원산지 효과가 보다 유용하다는 가설은 기각되었다. 이는 과거의 연구와는 달리 개발도상국-고품질 제품의 조합이라는 제품 특성 때문인 것으로 보인다. 또한, 마케팅 전술을 세우기 위한 특정 유통 경로가 원산지 효과에 영향을 미친다는 가설은 미국과 일본시장에서 모두 지지되었으며, 제품에 대한 정보 원천이 원산지 효과에 영향을 미친다는 가설은 미국에서만 지지되고 있음을 확인하였다. 또한, 이러한 결과를 바탕으로 토의 부분에서 한국의 고품질 농산품인 고려인삼의 효과적인 미국과 일본시장에서의 마케팅 전략을 제시하고 있다. Most of the previous studies concerning American or Japanese market have focused on the difference in COO effects between indigenous product mostly with positive COO effect and foreign products mostly with negative COO effect. and, the previous COO research has concerned with the electric home appliances like TV or automobiles while there has hardly been research concerning the COO effect and its application strategies on agricultural products. But, our exploratory research on the agricultural product extends the product categories regarding COO effects and our study is concerned with foreign product which has positive COO effects in American and Japanese market. We can observe that there exists the COO effect on ginseng in American and Japanese market. but we can find some results which are not consistent with the previous research - especially, in demographic factors of america and information source of Japan. We explain the reason of this results and suggest new strategy of COO. Also, we suggest the marketing process to make use of the COO effects, which can be applied various product categories.

The tandem network composed of the existing circuits network and packets network will integrate into a single network after this. that is, the circuit-based services of PSTN/ NISDN will integrate into the packet-based tandem network by using the devices of Media Gateway etc. moreover, because it is possible to multiplex the connections assigned to each subscriber by using AAL2 switching function of ATM network, we can heighten the utilization efficiency of network. In this paper, we described the VoDSL using an ATM tandem network and the call admission/ departure control algorithm, and appeared the performance estimation for the numerical results of multiplexer with bit dropping.

『管子』四篇 等에 나타난 精氣說 考察

崔昇勳,朴奭濬 대한동의병리학회 1993 동의생리병리학회지 Vol.8 No.-

연구배경 : 본 논문은 韓醫學 이론의 가장 기본이 되는 氣槪念의 역사적 형성 과정을 추적하여 한의학의 철학을 확립하기 위한 연구의 한 부분이다. 『黃帝內徑』이 저작된 시기를 전후하여 어떠한 사상적 흐름이 있었으며, 그것이 한의학 이론의 형성에 어떤 영향을 미쳤는지를 氣개념 형성을 중심으로 해명하고자 한다. 이를 위해 『管子』의 사상에 대하여 氣(精氣)論을 중심으로 알아보고 그것이 당시의 韓醫學 理論의 形成過程에 어떤 영향을 미쳤으며 그 결과 韓醫學의 내용과 방향은 어떻게 변해 갔는지를 알아보고자 하였다. 방법 : '『管子』四篇' 과 더불어 「水地」編, 「四時」編, 「五行」編 등을 주요한 연구 대상으로 하여, 당시의 시대적 배경과 사상사적 배경을 알아보고 특히 黃老之學의 내용이 무엇이었는지를 살피고 주제와 연관된 『管子』의 원문을 정리·분석하여 그 결과를 요약하는 것으로 한계를 설정하였다. 결과 : 戰國未에서 漢初에 걸친 사상계의 큰 흐름은 도가였으며 그 주류는 다름 아닌『관자』를 중심으로 한 黃老之學이다. 黃老之學은 단순한 諸思想의 集合이 아니라 "당대의 과학의 총채" 나아가 패러디임 혹은 사상의 전환으로도 이야기될 수 있다. 『관자』의 정기설은 고대의 氣개념과 '精'개념을 결합시킨 것으로 이는 '精氣一元論'이라고도 할 수 있는데 『內徑』의 精氣개념과는 그 기본 발상에서 일치하고 있다. 결론 : 養生이 精氣의 문제와 결합되어 의학이론발전에 많은 역할을 했다. 「水地」篇은 물이 만물의 근원이라는 입장에서 인체 역시 물에서 근원하는 것으로 본다. 한편 「水地」篇의 오행체계는 古文·今文의 문제와 함께 앞으로 연구해야 할 과제이다. 四象醫學의 '四元論' 역시 새롭게 연구할 대상으로 부각되었다. In order to investicate into the process of formation of Oriental Medicine Theory in ancient China Kuan Tzu(『管子』) may be a proper source. Especially five chapters of the text(「心術」上,「心術」下,「內業」,「白心」,「水地」) are abudant in the concept of 'Ch'i’or 'Jing'(精). The results of the analysis of Kuan Tzu are as follows. 1. Kuan Tzu was constituted in the time of Warring States and became one of the most important works of Huang-Lao school(黃老學派). Huang-Lao school is characterized by the unification of Taoists and Legalists. It was the summit of all sciences at that time, and became the basis of further unification of all thoughts. 2. Besides Kuan Tzu, the famous works of Huang-Lao school are Four Books of Huang-ti(黃帝內經),Huang-ti nei-ching(『黃帝內經』),Huai-nan-tzu(『淮南子』),Annals of Spring and Autumm(『呂氏春秋』), and they made a contribution to the establishiment of Confucian classics(經學). 3. Inspite of the concepts like Tao that is inherited from Taoism, Kuan Tzu proceeds the Taoism. That is, the concept of Tao in Kuan Tzu is more realistic and concrete than that of Taoism. Tao in Kuan Tzu is unificated into the concept of ‘Jing CH'i’(精氣), thus it may be called ‘Jing CH'i monism.’ 4. Kusn Tzu is combined with health preservation, so it contributed to the formation of medical theory, and is closely related with the formation of Huang-ti nei-ching. 5. The chapter ‘Sui-chi’(「水地」篇) recognizes Water to be a source of the world. Man is derived from Water, too. Water can be substituted for‘Jing CH'i’. So-called ‘Jing CH'i monism’is a fluent and open system. 6. The expression that “Water is a blood vessle in the Earth. It is just like the blood vessle in the body” gives us the fact that the concept of Meridian was generalized at that time. 7. The systems(arrangements) of Five Elements in Kuan Tzu are different from those of Huang-ti nei-ching. And the system of Sasang-EuiHak(四象醫學) is different from that of other medical systems. The reason why they are so different from each other should be invesgated into forward. These are the results of this paper.

The purpose of this study is to provide professional and amateur golfers with the basic guide to prevent injuries when playing golf. In order for that, the researcher has first researched the individual background of golfers and the parts, forms, and causes of injuries that they have according to their level of function. And also the researcher has taken a survey from professional and amateur golfers living in Seoul, Kyung-gi, and In-cheon in 2003. In order to compare and analyse these information gathered from each golfers about the injuries, questionnaires have been arranged on the basis of the studies of Batt(1992), Lee(1996), Roh(1996), Lee(1997), and Park(1998), Lee(2002). The appropriateness and validity of the contents of these questionnaires were verified after taking a preliminary test choosing each 20 of the professional and amateur golfers. Therefore, this source of questionnaires is believable with its high reliability. The statistic method in this study is frequency Analysis and x test. The results are as the followings. Injuries occur more to professional golfers than amateur golfers. And also they often have the skin injury and muscular injury because of the pressure they get to win the game doing over-exercise.

Cadmium, a potent toxic metal, posses a serious environmental threat but the mechanism of its toxicity remains unclear. Also, cadmium is a known immunotoxic agent in animal studies and induces pathophysiological effects by modulating components of immune system. Cytokines are being increasingly recognized as essential mediators of normal and pathologic immune response. Cells of mononuclear phagocytic system are strategically located at portals of entry in humans and therefore may be particularly at risk for cadmium exposure through contaminated air, food, and drinking water. In the present study, we investigated the effect of cadmium cytotoxicity for the monocyte and expression of cytokine gene in the control and cadmium treated human monocytic cell lines using RT-PCR method. The results showed that cadmium inhibited cell proliferation at 0.1mM cadimium treated cells for 24 hours. The TNF-α mRNA was expressed in both control and cadmium treated cells but not IL-6 and IL-1β. The mRNA levels of TNF-αwere examined during 24 hours culture period, at different time points. The expression of TNF-αmRNA increased in both 0.01mM and 0.1mM cadmium treated cells, but did not show dose-response relationship. According to cadimium treated duration, expression of TNF-αmRNA was more decreased in 24 hours than 6 hours. The decreased levels of mRNA of TNF-α suggest that cadmium suppresses its production at the transcription level.

We consider a step stress life testing which is deviced for a two-component parallel system with the considerable long life time. The purpose of this paper is to suggest an optimal time for changing the stress when the simple step stress life test is carried out. The life distribution is assumed as the ACBVE by Block and Basu(1974) and the expanded CE model is suggested for the bivariate case. The criterion for optimality is to minimize the variances of the maximum likelihood estimators of the mean life times under the normal stress.
