An investigation was carried out to compare the pulp responses against a few type of composite and streptococcus mutans contamination under the zinc oxide eugenol cement, and also confirmed pulpal responses of various composites with or without base. Seventy eight teeth from 6 dogs were employed and divided into 6 groups. Class V cavities were prepared on each tooth routinely with low speed dental engine. Paper disc about 0.3mm thick was immersed in the BHI broth in which streptococcus mutans had been enriched and the disc was inserted on the cavity floor prior to filling. Scotch bond puls Silux as Bis-GMA system composite resin and Helimolar as urethane system composite resin were adopted. Control group: Zinc-Oxide Eugenol cement filling Experimental groups: Group 1. Scotch bond + Silux filling with Dycal base Group 2. Heliomolar filling with Dycal base Group 3. Scotch bond + Silux filling without base Group 4. Heliomolar filling without base Group 5. Streptococcus mutans application. All cavities were sealed with thick ZOE cement to avoid marginal leakage. Postoperative intervals of 1, 2, 3, 4, 5 and 6 weeks teeth were carefully extracted, processed and stained with Hematoxylin and Eosin. The results were as follows: 1. S. mutans application group and composites without any base showed more severe pupal response than control group and dyca based groups. 2. The experimental group of S. mutans application showed severe response in the early stage compared to the two groups of composite resin without base, but no significant difference was found following periods. 3. The difference of pulpal response is not significant between Bis-GMA system and urethane system. 4. Streptococcus mutans application group and composites without base groups showed the evidence of histologic recovery at the six week cases and the large amount of reparative dentin was the prominent feature. 5. Pulp responses against every material were inclined to normal according to the time elapsed.

From the deliberation of the Statue of Artificers to its consent, both Elizabeth I and the Parliaments tried to gain benefits and make each one`s parth good respectively, keeping up mutual cooperaton as well. Elizabeth I, on the one hand, realzed her policy controlling the parliaments in the process of its deliberation by the Privy Council; and on the other hand, she had no choice to acknowledge and protect the interest of Parliaments since the Parliaments built and maintained her financial and military foundation. Elizabeth I had a conflict of interests against the group of Parliament, while pursuing the social order consistently, stabilizing the society and consolidating the economic basis. Based on the study of the background and nucles of Statues of Artificers, we can divide its contents and intention into three as follows; First, the group of Parliaents tried to consolidate their social and economic bases. Second, Elizabeth I sought to stabilize the society. Third, Elizabeth I and the group of Parliaments were able to make terms for the engagement qualification in the fields of commerce and industry.

본 연구의 목적은 1990년대 후반 이후 크게 성장하고 있는 스포츠서비스업 분야의 실태를 분석하고 발전방안을 도출하는데 있다. 이를 위해 스포츠소비와 스포츠서비스업에 대한 거시적 분석, 관람소비, 스포츠미디어 소비, 스폰서십, 정부정책 등에 대한 현황을 고찰하고, 스포츠서비스업체에 대한 구조화된 설문조사를 실시하였다. 업체 조사내용으로 사업현황, 조직 및 인력현황, 그리고 향후 사업전망과 사업희망 분야를 포함하였으며, 109개 스포츠서비스업체가 조사에 응답하였다. 조사결과 스포츠서비스업은 사업현황 면에서 영세성과 on-line 부문을 포함한 영업에서 부진을 나타내며, 경기업과 정보업에서는 사업 여건을 부정적으로 평가하고 있다. 조직 및 인력 현황에서 개인사업체가 상당수 있으며, 전문인력의 구성이 비교적 낮고, 마케팅업체와 정보업체는 대부분은 1990년대 이후 설립된 신규 사업체이다. 향후 사업전망에 대하여 마케팅업체는 비교적 낙관적으로 보고 있으며, 상당수 업체에서 스포츠마케팅업과 스포츠방송업에 대한 새로운 적극적 관심을 나타내었다. 마지막으로 이러한 실태분석에 기초하여 스포츠서비스업 사업체가 추진해야 할 발전방안과 정부 및 지자체 등의 공공부문에서 추진해야 할 발전방안을 제시하고, 이러한 두 분야의 발전방안이 동시적으로 추구될 때 스포츠서비스업의 성장과 발전이 이루어질 수 있음을 강조하였다. With the increase of economic values of sport, the sport industry has taken the important position in terms of gross domestic product(GDP). Sport service business as a branch of sport industry has rapidly grown as people`s leisure time increases and the consumption of sports become a popular cultural form. This study attempted to investigate the current status of sport service industry and to discuss the future strategies for developing that industry. The questionnaire method was employed to figure out the business, organization, and personnel situation of sport service industry and 109 companies were investigated. The results showed that the current business of sport service industry doesn`t seem to be profitable and competitive: many sport service companies lose the money, on-line business is rudimentary, there are few professional staffs, and the organizational structures of some companies are less efficient. Many companies are interested in sporting marketing as the new business item and some are thinking about launching sport broadcasting business. The 10 future developmental strategies for sport service industry were suggested and discussed: the companies need to increase their own business competency and organizational effectiveness and public sector needs to establish the sport service infrastructure. The cooperation between private and public sector seems to facilitate the development of sport industry including sport service business.

This study suggests strategy for building information infrastructure of newly established small organization. Based on previous literatures, this study recommends outsourcing strategy which is consisted of 8 points. The suggested strategy includes considerations for building information infrastructure and maintaining it and they are verified with cases. I expect this study gives useful guideline for small organization's information infrastructure building.
사회체육운동의 이념적 배경으로서 1920-30년대 유럽의 노동자 스포츠운동

This study dealt with 1920-30`s worker sport movement in Europe as philosophical backgrounds of sport for all movement. Two main theme were discussed as the characteristics of the 1920-30`s worker sport movement in Europe; one was `sport for all` and the other `participation` rather than `competition`. The ideal for `sport for all` enabled the majority including workers, peasants, women and color of people to involve in sport through their sport organizations. The ideal for `participation rather than `competition made a contribution to building solidarity and togetherness among workers beyond nationality. These two mottos, initiated from `the bottom in social hierarchy`, were concretely expressed as `anti-bourgeoisie`, `anti-commercialism`, `anti-elitism`, and `anti-discrimination based upon skin color` and developed with the socialist labor movement. But worker sports were largely considered as the instrument for class struggle against the bourgeois; worker sports played an important role in building workers` solidarity and class consciousness. Sport itself was not the end for participating individuals but only the means for participating class; the individual enjoyment and satisfaction through sport participation were secondary but the class collective interests were primary concerns. Finally this study argues that the positive sides of worker sport movement, `sport for all` and `participation-oriented`, need to be revived and maintained with the critical review of current sport for all movement which has been deteriorated into `elite sport model`.
