In 24 men and 12 women recovery of heart rate after strenuous exercise was observed before and after administration of total ginseng glycosides. In men 100 mg of ginseng glycosides were given twice with a 3 hour interval on the day of treadmill test and in women two more administrations of ginseng glycosides were added on the day before the exercise test. The action of ginseng glycosides was interpreted as an adaptogen, i.e., to enhance the recovery to the physiological equilibrium from the displace4 state. Recovery of heart rate to the pre-exercise state was observed for 20 minutes after strenuous exercise of 2 minutes duration on a treadmill (8 km/hr, 15% grade). In men the recovery of heart rate was enhanced$(P<.2{\sim}.4)$ after ginseng glycosides administration. In women the acceleration of recovery heart rate was highly significant $(P<.01{\sim}.05)$ after ginseng glycosides administration. In men and women recovery heart rate at 3 minute of recovery period after ginseng glycosides equaled to the value at 6 minute of recovery period before ginseng administration.
일반화된 자기일치모델과 수정된 에쉘비 모델을 이용한 나노유체의 등가열전도계수 예측에 대한 연구

복합재의 물성치 해석에 일반적으로 사용되는 일반화된 자기일치모델(Generalized Self-Consistent Model)과 수정된 에쉘비모델(Modified Eshelby Model)을 이용하여 나노유체의 열전도계수를 예측할 수 있음을 보였다. 이 유체의 열전달효과를 대폭 향상시키는 대표적인 메카니즘 중 하나인 나노입자와 기본유체 사이에 존재하는 나노층의 영향을 고려하여 나노유체의 열전도계수를 예측하였다. 본 연구는 나노층의 열전도계수가 일정한 값을 가질 때 기존 대표적인 모델과 동일한 결과를 보였으며, 선형적으로 변할 때 역시 문헌에 있는 모델과 동등한 수준의 예측 값을 보였다. 알루미나와 산화구리를 나노입자로물과 에틸렌글리콜을 기본유체로 한 나노유체의 열전도계수에 대한 실험결과와 본 모델의 예측결과를 비교함으로써 본 모델의 타당성을 입증하였다. Effective thermal conductivity of nanofluids has been predicted by using generalized self-consistent model and modified Eshelby model, which have been used for analysis of material properties of composites. A nanolayer between base fluid and nanoparticle, one of key factors for abrupt enhancement of thermal conductivity of nanofluids, is included in the analysis. The effective thermal conductivities of the nanofluid predicted by the present study show good agreement with those by models in the literature for the nanolayer with a constant or linear thermal conductivity. The predicted results by the present approach have been confirmed to be consistent with experiments for representative nanofluids such as base fluids of water or ethyleneglycol and nanoparticles of Al₂O₃ or CuO to be validated.

The purpose of this study is to investigate the impact of urban tourism Behavior patten on urban image influence upon Visit satisfaction and Behavioral intention, There are 3 hypotheses based on urban tourism reviews, Then we tested the data from questionnaires using SPSS 17,0, The data were collected from September to November, First, it is higher urban imagination of business-travelers who visited Incheon than Seoul , Second, vacation travelers who visited in Incheon are also higher than Seoul, Third, four facts out of six as cognitive facts of urban image influenced on visit satisfaction, Last, visit satisfaction influenced on behavioral intention, The result of this study on impact of urban tourism Behavior patten on urban image influence upon Visit satisfaction and Behavioral intention show that there is a purpose to know a realistic character and to become a big power of tourism nation in the world,

This study was conducted to come up with strategies both for the current urban brand value management of some cities as well as for their future brand management. In order to achieve the research goal, the study measured brand equities of those major cities which are being evaluated as the biggest tourist cities in the world, and compared their brand equities with each other. In addition, before evaluating the brand equity of Seoul from an aspect of the urban tourism belt, the study selected three cities, New York, Boston and Washington, as sample cities to be compared with Seoul. As for the empirical analysis, the study extracted a total of 342 samples from tourists who have toured the research subjects, those four urban tourism belt brands. The key results are summarized as follows. Regarding the brand strength as in the future value of the urban tourism belt, all of the sample cities came up with high scores on relevance. It was also analyzed that the brand stature as in the current value has high scores on knowledge. Add to that, in terms of the general scores on the brand equity of the urban tourism belt, the scores on the brand stature appeared high. This study is considered academically significant for it has applied this BAV model not only to re-establishing the concepts of the urban tourism belt and measuring the brand equity but also to evaluating tourists`` perceptions towards various brands.

The purpose of this study is to investigate the impact of affective image by urban tourism foreign tourists` country on visit satisfaction and revisit intention. There are 3 hypotheses based on urban tourism reviews. Then we tested the data from questionnaires using SPSS 18.0. the data were collected for a month from March 31 to April 30. First, according to analysed result, Chinese-speaking country`s urban tourists is higher the affective image of urban tourists visiting Seoul about 2 facts which are uniqueness and amenity than English-speaking country. Second, three out of four as affective facts of urban image influenced on visit satisfaction. Last, visit satisfaction influenced on revisit intention. As the result of this study, we will attract English-speaking country`s tourists with better tourism products. And if Seoul makes use of public relations of traditional image to foreign tourists because traditionality didn`t influence on foreign tourists, They will feel higher visit satisfaction levels in visiting urban. For this reason, Seoul will have to try to show the indigenous culture of Korea.

Exhibition-Event as mans of a struggle for existence marketing for company or nation have become ones in witch spectators actively take part in the aspect of a scheme and event factors have been emphasized in planning theme since the beginning industrial society. In this situations, eechibition-event has been a plan of efficient marketing promotion and displaying to make objects consurre-s and buyers. This thesis is aimed to verify eachibition-event effect, to be considered in the cotese of administration planning exhibition. therefore the administration planning obtained are as follow : establishing of planning, preparing in advance, a work of participation books, peepaW g the opaiing, managing of an exhibition, analysis of result, and exact calculation. This study eredeavcue to present a adrrinistration planning about the increase of exhibition-event in quantity and quality which will grow. I hope that this study will give some help to producer and enteaepaise managers.
