Purpose : This study was designed to evaluate the efficacy and utility of panoramic radiograph for the improvement of the periodic oral examinations. Materials and Methods : Clinical examinations and panoramic examinations were done for the 242 subjects of oral examinations. The results of panoramic radiograph interpretation were compared with the clinical findings. Two questionnaires were created. One was carried out before the panoramic examination and the other done afterwards, to find out the subjects' cognition and satisfaction for the clinical and panoramic examinations. Results : 1. Panoramic findings showed a higher detection rate of 31.9% for periodontal diseases, and 23.1% for dental caries than clinical findings. 2. The additional abnormalities detected through panoramic examinations were impacted tooth in 81 subjects (33.6%), maxillary sinus abnormalities in 28 subjects (11.6%), condylar abnormalities in 5 subjects (2.1%), congenital and acquired dental anormalies in 59 subjects (24.5%), and other miscellaneous abnormalities in 34 subjects (14.1%). 3. 164 subjects (67.8%) were satisfied with the current periodic oral examination, and 75 subjects (31.1%) hoped for better accuracy. 4. In the first and second questionnaire, 154 subjects (67.0%) and 163 subjects (70.6%) responded respectively that panoramic examination was necessary, and 193 subjects (83.2%) responded that it actually helped. Conclusion : The panoramic examination was revealed to improve the effectiveness of the periodic oral examination and to increase the satisfaction of the subjects of examination.

A nearly equatomic nickel-titanium alloy(Ni-Ti alloy, Nitinol) is a metal alloy composed of Ni and Ti around 50% respectively in that it possesses a so-called shape memory. Nitinol can be put use for various applications which need purity and high precision surface of product using surface treatment methods. So, ectropolishing is adopted to final polishing of nitinol. Electropolishing has been used in metal alloy, but its essential details and electropolishing mechanism for nitinol have not been reported yet as a demand. So, the aim of this study is to investigate the characteristic of electropolishing nitinol in terms of current density, polishing time, electrode gap. And the optimum experimental condition about each parameters was obtained using by response surface methodology.

온라인 비디오 게임 사용과 사회성 연구의 주요 쟁점에 관한 문헌고찰

신민정(Min Jung Shin),이경민(Kyoung Min Lee),유제광(Je-Kwang Ryu) 한국인지과학회 2020 인지과학 Vol.31 No.3

사회성은 인간 삶의 고유 영역이자 종합적인 능력으로서 중요한 가치를 지닌다. 일반 통념상 사회성 부족이 게임 이용의 대표적인 문제점으로 지적되는 가운데, 본 문헌 고찰에서는 비디오 게임 중 온라인 비디오 게임을 대상으로 사회적 역량과의 관계를 살펴본 연구들을 분석했다. 해당 분야에는 현재 온라인 게임안의 관계가 실제 관계를 대체하거나 보완하여 사회성 발달을 저해할 것이라는 견해와 온라인 비디오 게임이 직접적으로 사회성에 악영향을 미치지 않으며 오히려 사회적 학습의 공간을 제공함으로써 유익한 결과를 낼 수 있다는 주장이 팽팽하게 맞서고 있다. 또한 온라인 게임 이용과 심리특성 및 사회적 역량을 측정한 대규모 설문 조사에서도 게임 이용과 사회성 저하 간의 뚜렷한 관계성이 관찰되지 않았다. 이에 본 문헌 고찰 연구를 통해 온라인 게임 플레이가 사회성 저하를 초래한다는 고정관념에서 벗어날 것과 관련 연구의 타당성을 높이기 위한 노력이 필요함을 제안한다. Sociability is an inherent part of human life and also possesses an important value as a comprehensive ability. While the lack of sociability has been pointed out as a representative problem of game use in general, this paper analyzed studies on the relationship between online video games and social competence. In this field, the view that the relationship in the online game may replace or complement the actual relationship and will potentially hinder the development of sociability currently faces a conflict with the opinion that online video games may not directly have a negative effect on sociability but rather result in a positive outcome by providing a social learning space. In a large scale survey that measured the use of online games, psychological characteristics, and social competence, no distinct relationship between game use and degradation of sociability was observed. Based on this analysis, we suggest that efforts are necessary to break away from the stereotype that online game play may cause a decline in sociability and to improve the validity of related research.

신민정(Min Jung Shin) 한국복지행정학회 2022 복지행정논총 Vol.26 No.2

본 연구는 자발적 주민조직에 참여하고 있는 주민의 지역사회 애착과 주민조직 참여 간의 관계에서 집합적 효능감의 조절효과를 검증하는 것을 목적으로 한다. 연구대상은 활동기간 3년 이상의 자발적 주민조직이며, 사용된 측정도구는 지역사회 애착, 주민조직 참여, 집합적 효능감의 세 가지 척도이다. 수집된 데이터는 사회과학 통계프로그램인 PASW Statistics Ver.18을 이용하여 주요변수 간 상관관계를 분석하고, 조절효과분석을 실시하였다. 본 연구를 통하여 밝혀진 주요 결과를 요약하면 다음과 같다. 첫째, 자발적 주민조직에 참여하고 있는 주민의 지역사회 애착, 주민조직 참여, 집합적 효능감 사이의 상관관계를 분석한 결과, 모두 정적인 상관관계를 나타내며 통계학적으로 유의미하게 나타났다. 둘째, 자발적 주민조직에 참여하는 주민의 지역사회 애착과 주민조직 참여의 관계에서 집합적 효능감의 조절효과가 나타났다. 셋째, 집합적 효능감의 하위변인인 사회적 응집력, 비공식적 통제의 조절효과를 살펴본 결과, 지역사회 애착과 주민조직 참여 간의 관계를 두 하위변인 모두 각각 조절하는 것으로 검증되었다. 이러한 연구 결과를 바탕으로 본 연구의 의의 및 주민조직 참여를 위한 제언과 시사점에 대해 논의하였다. The purpose of this study is to verify the moderating effect of collective efficacy on community attachment and participation in resident organizations of residents participating in voluntary resident organizations. The subjects of the study were voluntary resident organizations with an activity period of more than 3 years, and the measurement tools used were three measures: community attachment, resident organization participation, and collective efficacy. For the collected data, correlations between major variables were analyzed using PASW Statistics Ver.18, a statistical program for social sciences, and moderating effect analysis was conducted. The main results revealed through this study are summarized as follows. First, as a result of analyzing the correlation between community attachment, participation in resident organizations, and collective efficacy of residents participating in voluntary resident organizations, all of them showed static correlations and were statistically significant. Second, there was a moderating effect of collective efficacy in the relationship between community attachment and participation in resident organizations of residents participating in voluntary resident organizations. Third, as a result of examining the moderating effects of social cohesion and informal control, which are sub-variables of collective efficacy, it was verified that both sub-variables each moderated the relationship between community attachment and participation in resident organizations. Based on these research results, the significance of this study and suggestions and implications for participation in resident organizations were discussed.
