Statement of problem : Since the concept of osseointegrated dental implant by $Br{\aa}nemark$ et al was first applied to mandibular full edentulous patients. Recently it is considerated the first treatment option on missing teeth. A common problem associated with dental implant restorations is loosening of screws that retain the prosthesis to the abutment and the abutment to the implant fixture. Purpose : This study is to examine the influence on screw loosening of implant-abutment designs. Material and methods : External hex, cone screw, beveled hex, cam cylinder, cylinder hex by means of evaluating the loosening torques, with respect to a range of tightening torques after repeated loading. Result : 1. Cone screw, beveled hex groups are the highest initial tightening rate and cylinder hex, external hex groups are the lowest initial tightening rate (p < 0.05). 2. Cone screw groups are the highest after repeated loading tightening rate and cylinder hex groups are lowest after repeated loading tightening rate(p < 0.05). 3. Cone screw groups have the highest initial stability and anal stability. 4. All groups are decreased tightening rate after repeated loading.

Today, Korea is changing to leisure society. With that stream, leisure becomes important policy area due to the roles of meeting desires for better quality of life, promoting social integration and industrial resource. But in case of Korean leisure policy, it still has no independent policy area because of unclear object and high relations with similar areas like culture, sport and social welfare. So, this study suggests arguments on identity of leisure policy, to confirm independent area of leisure policy for comprehensive policy making. First, in terms of policy purpose, precedent leisure policies and studies have suggested improvement of life quality as eventual purpose of leisure policy, mainly. But improvement of life quality is common goal of most public policy, so, that can’t confirm identity of leisure policy. On the other hand, in case of advanced countries and some independent leisure policies, they set getting leisure life or promoting of leisure culture as goals. Thus, to confirm identity of leisure policy and get independent policy area, it is needed to set leisure’s own policy goals as highest purpose under eventual goal for improvement of life quality, and try to practical application of that in actual fields. Second, in terms of policy instrument, precedent leisure policies and studies have tried to include the other policy area’s means having even small relations. But those attempts would confuse identity of leisure policy, because those policy means would treat leisure as instrument, but not goals, and change characteristics of leisure policy through that. Therefore, to confirm leisure policy’s identity, efforts to search leisure policy’s own goals and recognition changes to distinguish policy means treat leisure as instrument should be performed. Third, in terms of policy target, precedent leisure policies and studies have classified and set targets by metrics of social welfare, economical and social status. Thus, to confirm identity of leisure policy, from the perspective of social right of leisure, leisure policy targets should be set according to levels of leisure participation capability as leisure’s own standard.

This study has an aim to construct a reference frame to analyze the appropriateness of environmental education(EE) materials of elementary schools, and to search the basic direction of the scheme for analysis. In addition, this study has an aim to induce what the results of this analysis suggests for the development and reconstruction of EE materials. It was analyzed how truly EE materials reflected contents selected as an analysis scheme, after grasping practical use and features of textbooks, audio-visual materials, and a web-site that are typical materials in EE of elementary schools.<br/> The results in textbook analysis were that there were a human-centered environmentalism in the EE unit (Environmentally Sound National Development, 5th Grade) of Social Studies. The result in analysis of audio-visual materials Environmental Warrior, Zentaforce of EBS, were that there are unhealthy environmentalism in that material. In other words, technology itself is considered as a almighty means to solve environmental problems.<br/> Finally, the result in web-site analysis were that the Environmental Class of Ministry of Environment did not have sound environmentalism. <br/> The above result of study shows us that the most important thing in developing and using the environmental education materials is to have sound environmental values and EE perspective, to evaluate EE material with various point of view, to judge its result, and to use it.

스포츠 경기의 특성에 따른 스포츠 감정 유형 분석 : 소셜 빅데이터를 중심으로

김영미,양재식,Kim, Young-Mee,Yang, Jae-Sik 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.7

본 연구는 스포츠 경기의 특성에 따른 스포츠 감정 유형을 분석하였다. 이를 위해 2018년 아시안게임 중, 대한민국 대표팀이 출전한 축구 7경기, 야구 6경기를 선정한 후, 이에 대한 소셜 네트워크 서비스 상 기사와 그 댓글을 조사대상으로 선정하였다. Python을 이용하여 수집된 댓글은 전문가 회의를 통해 해당 감정을 분석하였다. 스포츠 경기의 승패, 상대 팀의 수준 및 대한민국 대표팀의 경기력에 따른 스포츠 감정을 분석한 결과, 첫째, 승패와 상대 팀 수준은 특정한 유형의 스포츠 감정을 형성한다고 보기 어려웠다. 둘째, 스포츠 경기의 경기력은 좋다는 평가를 받을 경우 만족, 열광, 기쁨 등의 긍정적 감정을, 나쁘다는 평가를 받을 경우 실망, 분노, 창피의 부정적 감정을 형성하였다. 셋째, 스포츠 경기와 연관된 사회·문화적 배경이나 해당 경기의 특정한 사건 또한 스포츠 감정의 유형에 영향을 미쳤다. 추후, 본 연구에서 다루지 못한 다양한 스포츠 경기의 특성을 추가하여 보다 많은 스포츠 경기를 대상으로 분석하는 연구가 필요할 것이다. This study tried to analyze the types of sport emotion by sport game characteristics. For that, 7 soccer games and 6 baseball games of Korean team in 2018 Asian Games were selected, and the articles and their replies about those on social network services were collected as study materials. Python was used for the collecting and expert group meeting was held for the emotion analysis. As the results of the analysis on sport emotion types by win or lose, the level of opponents and the performance of Korean team as game characteristics, the following conclusions were drawn. First, it was hard to say that win or lose and opponent's level make certain sport emotion type. Second, The performance could made contended, enthusiastic and joyful emotions when judged good, but frustrated, angry, humiliated emotions when bad. Third, social·cultural background or certain event of the games also could effect on the sport emotion types. Follow-up studies with the other game characteristics and more game cases were needed to find out more clear causal relationship.
