The rapidly change of business environments have been required new trade channels as a electronic commmerce(EC) in recent times. The EC is expanded to every part of trade channels in order to achieve goals such as cost-down, quality upgrade, and speed-up of service delivery. In this aspect, internet provides chances like worldwide network, feasible share of information, and low price, and has great influence on the growth and development of EC. This paper discussed to provide a comprehensive coverage of the concept of EC and EC service quality. In addition, this study empirically analyze relations between service quality of EC and CS, and their Repurchase intention and Demographic charcteristics. This means that research enables a marketing manager to take the meaning of comparative weight among the components of EC service quality, and to provide very useful information to establish marketing strategies which are close to the consumers.

Changes of peripheral arterial oxygen saturation(SaO_2) were compared according to the methods of extubation after general anesthesia in 44 pediatric patients in TaeJon ST.Mary's Hospital between March and May in 1992. Patients were divided in two groups. Group Ⅰ (n=22); endotracheal extubation was performed with suctioning by catheter after one or two endotracheal suctions. Group Ⅱ (n=22); endotracheal extubation was performed wit positive pressure administration of 100% oxygen by reservoir bag simultaneously after one or two endotracheal suctions. All patients were administered 100% oxygen for one minute after extubation and transferred to recovery room and administered oxygen 3ℓ/min by face mask for three minutes. The results are as follow: 1) SaO_2 was decreased significantly (p<0.05) after extubation in group Ⅰ compared with control and group Ⅱ. 2) The number of patients whose SaO²bellow 95% are increased in group Ⅰ(77%) compared group Ⅱ(5%) after endotracheal extubation. 3) SaO_2 of all patients were recovered to over 99% after administration of oxygen for three minutes in recovery room.

In order for electronic commerce to be successful, it must have a theoretical framework that considers the characteristics of the internet user who are consumers in the cyber space and impacts their purchase intentions. We were able to obtain participations of 316 people, and derived statistics by means of SPSS/PC version 10.0 and Amos 4.0 statistics package. We found that, the higher the degree of skill and the sense of challenge, the level of involvement and perceived service quality increased. And the degree of skill has a negative influence on awareness of perceived risk than the sense of challenge. Perceived service quality, perceived risk and involvement has a influence on purchase intentions.

Consumer satisfaction is an important concept in marketing practice and theory. Because today's marketing base is consumer-oriented, as a realistic guide, consumer satisfaction is a useful concept. This concept emphasizes delivering satisfaction to consumers and obtaining profits in return, and as a result, the overall quality of life is expected to be enhanced.

최근 역타시공법 등에 의한 콘크리트 구조물의 시공이 증가 추세에 있다. 이 경우, 자주 발생되는 신ㆍ구타설 콘크리트 시공이음부의 공극은 향후 구조물의 구조적인 특성과 내구성 등에 큰 영향을 미치게 된다. 그러나 현재 제안되고 있는 비파괴 검사법으로는 효과적으로 이음부 공극을 평가하기에 많은 한계가 있다. 본 연구에서는 시공이음부의 콘크리트 충전상태를 평가하기 위해 철골철근 콘크리트와 무근 콘크리트 시험체내에 공극을 모의제작한 후, 초음파속도 측정을 실시하고, 화상처리기법을 이용하여 비교적 용이하게 해석 가능한 방법에 대해 검토하였다.

Macrophage play a major role in host defence against infection and tumor development and this activity is regulated through the production of several mediators. In particular, the production of N0 by macrophages mediates killing or growth inhibition of tumor cells, bacteria, fungi and parasites. However, over-expression of iNOS by various stimuli, resulting in over-production of NO. contributes to the pathogenesis of septic shock and some infmammator and auto-immune disease. Thereforc, it would be valuable to develop potent and selective inhibitors of for potential therapeutic use. Thus the agent that supprees the expression of iNOS mRNA or enzyme protein will be usefull for the prevention of various diseases. We are intersted in identifying selective inhibitiors of iN0S which might be useful intreating inlammatory human diseases. In summary, we have demantrated that scopolein, isolated from Seman Armenicae and Radix Trichosalmis the production of NO induced by IFNy plus LPS in RAW 264.7 macrophages, The mechanism for the inhibition of N0 Production was due to suppression of the expression of iN0S mRNA or enzyme protein.

The joint and void treatment of concrete is one of the technical problems in construction. Joints and voids created with the construction result in serious weakness from the aspects of both structural and water-barrier function. Ultrasonic image processing technique was used for the inspection of construction joints of SRC(Steel-frame Reinforced Concrete) column and voids of concrete block in this study. The advantages and limitations of this technique for non-destructive inspection in construction joints and voids are investigated. As a result, it has been verified that the semi-direct measurement type is more effective than the other types for detecting the construction joints and voids using ultrasonic method.

As the technique of automobile industry is being advanced, the advancement of performance for vehicle is being required. In order to achieve this purpose, the study on the handling and stability which are produced by moving vehicle is carried out actively. Ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers. From the previous research. we showed that handling simulation tool developed for J-turn and lane change maneuvers on ADAMS could be used in predicting the performance difference among tires with different specifications in vehicle mild handling behaviors. Through this study, some meaningful correlations were achieved. Also barriers to direct application of the simulation technique to tire development process and several technical problems that should be resolved were iden tified. In this results, ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers.
