Health industry, a knowledge based high value-added industry, is being considered as a strategic area for the 21C and many advanced countries are making every endeavors for the promotion of health industry along with information technology, new materials, and mechatronics. Korean health industry, however, has been excluded from the governmental supports as well as bound by strict regulation so far, and there is a significant gap in technology compared with advanced countries. In 21C, technology is the main factor of national competitiveness and that is why the role of R&D institutes are so important in the high level of competition to cope with the technology protection policies of advanced countries. In this article, with Directory of Korean R&D Institutes published by Korea Industry Technology Association, I reviewed the trends of R&D institute of health industry. Main findings of the research can be summarized as follows. The portion of health industry R&D institute is 3.6% of total R&D institute but the amount of R&D investment is over than 5% This means health industry are knowledge based and R&D intensified industry, meanwhile the variations of same industry R&D institutes of health industry is huge in R&D investments and other activities. Regional distributions of health industry institutes show some kind of different patterns in each industry areas. Medical devices and Medical informatics's preference of metropolitan region are distinguished with other industry areas. Many of the institutes are located in same site of it's company rather than operating separate building for R&D specific uses. It is better for transforming ideas to products and close cooperation of research body with product lines, but it is a handicap for networking and communicating with other research institutions too. It takes 18.4yrs for bearing R&D institute on the average. For a long times 'copy products' or 'me too products' policies were easy way to maintain business entities. But recently, it is recognized that research activities are essential component of sustaining it's own business firms. This means technology itself is leading power of corporation itself in the high level of competition.

본 연구는 All-In-One system의 적용 시간과 도포횟수에 따라 유치 상아질과 복합레진의 접착 강도와 혼성층에 어떤 영향을 미치는지를 규명하고자 Single bonding agent(Scotchbond Multi-Purpose Plus, 3M, USA)와 All-In-One system(Prompt-L pop, 3M ESPE, USA)를 사용하였고 수복용 레진으로 복합레진(Z-250, 3M, USA)를 사용한 결과 다음과 같은 결과를 얻을 수 있었다. 1. 전단 결합 강도는 Single bonding agent를 적용한 경우 All-In-One system을 적용한 군보다 유의하게 높게 나타났다(P<0.05). 2. Prompt L-pop을 2회, 3회 적용한 경우에 전단 결합 강도는 1회 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 혼성층의 두께는 1회 적용군보다 2회, 3회 적용한 군에서 증가하였다. 3. Prompt L-pop을 15초 적용한 경우에 전단 결합 강도는 7초 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 30초 적용군과는 차이가 없었다. 혼성층의 두께는 7초 적용군이 가장 얇고, 15초군과 30초군에서는 차이가 없었다. 4. Single bonding agent를 이용한 경우 두터운 $2-4{\mu}m$의 혼성층이 관찰된 반면, All-In-One bonding system(Prompt L-pop, 3M ESPE, USA)에서는 비교적 얇은 혼성층($1-2{\mu}m$)이 형성되었다. The purpose of the present study was to evaluate the patterns of hybrid layer according to the application time and the frequency and its effects on the shear bonding strength of All-In-One system in primary teeth. A single bonding agent(Scotchbond Multi-Purpose Plus, 3M) and an All-In-One system(Prompt L-pop, 3M ESPE) were applied on the dentin varying the application time and the frequency in primary teeth. Shear bond strength was measured and the patterns of hybrid layers were observed by SEM. The following results were obtained ; 1. The shear bonding strength of single bonding agent was significantly higher than that of All-In-One system(P<0.05). 2. The shear bonding strength of All-In-One system applied twice or 3 times were higher than that of applied once (P<0.05). And thickness of the hybrid layer was increased when applied twice or 3 times compared to once. 3. The shear bonding strength of All-In-One system when applied for 15 second and 30 second were higher than that of 7 second (P<0.05). And the hybrid layer thickness of 15 second and 30 second's application time were higher than that of 7 second. 4. Thickness of hybrid layer applied with single bonding agent was $2-4{\mu}m$ and that of All-In-One system was $1-2{\mu}m$.

The purpose of this study was to examine the relation between thoracic scoliosis and gastroenteric disorder. In this article, We surveyed sixty two patients and investigated through a questionnaire the health and meal habits, digestive trouble levels, stress levels(BEPSI-K), and the stress response index(SRI). Participants were classified according to each group in over 10°(vertebral scoliosis), under 10°(functional scoliosis) and made a diagnosis of X-ray of scoliosis grade. The data was took statistics on two group by independent t-test, chi-square test with SPSS/PC+ 10.0 program. The statistically significance was a p<.05 and the following results were obtained; 1. In general characteristics, The thoracic scoliosis was as many as women, weight 50-60kg, height 160 -170cm, married person. 2. Relations between health and meal habit with thoracic scoliosis was not statistically significant(p>.05). 3. Relations between thoracic scoliosis and digestive trouble level was statistically significance (p<.05). 4. Relations between thoracic scoliosis and incidence rate of internal disease was statistically significant(p<. 05). 5. Relations between thoracic scoliosis and stress(BEPSI-K) was statistically significant(p<.05). 6. Relations between thoracic scoliosis and stress(SRI) was statistically significant(p<.05). These results lead us to the conclusion that thoracic scoliosis influences digestive trouble, incidence rate of internal disease and stress. However, there results are not easy to explain because of the limitations of a few subjects and a single comparison. Therefore, further research on this study thoroughgoing inspection would clarify the association of thoracic scoliosis and gastroenteric disorders.

The purpose of this research was aimed to find out what kinds of assessment factors associated with website have on user`s satisfaction and revisit intent in the context of tourism. A research model that had been formed to find the tourism website assessment factors was based on several empirical studies up to the present. We adapted those studies to tourism information context by combining existing researches on general assessment factors and quality assessment factors. The model incorporates two assessment factors dimensions including the trust, usefulness, playfulness. convenience. economy. expression in general assessment factors and information quality, system quality, service quality in website quality assessment factors. And an attempt was made to empirically examine the relationship between variables of these dimensions, user`s satisfaction and revisit intent. The results of this study revealed that five general assessment factor variables and three quality assessment factor variables were found to significantly contribute to the user`s satisfaction and intent to revisit the site. But expression in general assessment factors had no positive influence on user`s satisfaction. The paper concludes that the assessment factor dimensions can serve as a useful framework to evaluate the quality of tourism information websites in an attempt to improve the user`s satisfaction with the website.
