최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

홍용신,박은진,김성균,곽재영,허성주,박지만 大韓齒科保存學會 2011 Restorative Dentistry & Endodontics Vol.36 No.6

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

신은경,이익섭,손주영 한국장애인고용촉진공단 고용개발원 2009 장애와 고용 Vol.19 No.2

청각장애인은 고용상태가 불안정하며, 삶의 속도가 빨라지는 정보화 시대에 사회통합에 필요한 실제적인 지원체계가 결핍된 채 살아가고 있다. 이러한 상황은 그들의 장애정체감을 왜곡시키고, 타인과의 관계형성에 어려움을 겪게 하며, 나아가 사회통합을 저해하고 있는 것이다. 이에 본 연구에서는 청각장애인의 사회통합에 영향을 미치는 결정요인을 고용유무, 문제실제지지, 장애정체감, 사회적 교제관계로 설정하고 각 영향요인과 사회통합의 관계 경로를 검증해 보았다. 본 연구는 전국에 거주하고 있는 청각장애인 134명을 대상으로 조사하였으며, 확인적 요인분석을 통하여 분석한 결과, 모형의 적합도는 좋은 적합도(close fit)를 보여주었다(TLI .912, CFI .942, RMSEA .049). 변수 간의 관계구조의 검증결과를 보면, 청각장애인의 문제실제지지는 장애정체감에 정적영향을 주며, 장애정체감은 사회적 교제관계에 정적영향을 주고 있었다. 또한 사회적 교제관계는 사회통합에 정적영향을 주었다. 고용유무는 사회통합에 직접효과를 가진다고 검증되었다. 본 연구를 통하여 청각장애인의 고용에 관한 정책적 지원과 그들의 문제를 구체적이고 실제적으로 지지해줄 수 있는 체계의 마련이 필요함을 알 수 있었다. 이러한 지원체계의 마련이 궁극적으로는 사회통합에 영향을 주며, 동시에 장애인의 긍정적 정체감 형성을 돕고, 친밀한 대인관계를 형성하게 되는 것에도 효과가 있음이 검증된 것이다. The condition of employment the deaf is unstable, and they are maintaining their life with lack of practical support system for social integration in this fast turning information-oriented society. These circumstance distorts their disability identity, distresses on having relationship with other people, moreover it is hindering social integration. At this point, the study verifies the effect factors of the deaf to integrate in society by setting up an employment status, a disability identity, a problemoriented instrumental support and a social association relationship. This research targeted 134 the deaf group from the whole country, and by analyzing confirmatory factor analysis, it revealed suitability of the model is close fit(TLI .912, CFI .942, RMSEA .049). A result for verification in relationship system among variable is that, problemoriented instrumental support has positive relationship with the deaf ’s disability identity and disability identity is also related with social association relationship in affirmative way. It verified that an employment status has direct effect on social integration. Through this research, we felt the necessity of providing the political support for the employment and the system which could sustain their problems concrete and practically. By providing these supports, it will bring a good effect on social integration ultimately, and simultaneously, it will help disabled to form an positive identity, and it verified that it will support them to make a intimate personal relations.

신위재,주창복,고은배 慶南大學校 附設 工業技術硏究所 1993 硏究論文集 Vol.11 No.-

본 연구에서는 제어시스템에서 필연적으로 발생하는 오브슈터(overshoot)와 정상상태오차를 줄이기위해 P-D(Proportional-Derivation)부가 SOFC (Self-organizing Fuzzy Control)를 설계하였다. 제어규칙 생성에서 전문가 지식과 시행착오의 반복수행에 대한 계산시간과 메모리 용량을 줄이기 위해 변형된 P-I-D 앨고리듬이 사용되었으며 P-D제어기에서 발생되는 오브슈터의 증가를 P-D부가 SOFC로서 해결 하였다. 본연구에서 제안한 설계방법의 타당성을 로보트 매니퓰레이터의 컴퓨터 시뮬레이션으로 확인하였다. In this paper, PD plus SOFC is designed to reduce the steady state error and overshoot which is easy to occur in system control. And modified PID algorithm is used to decrease calculation time and memory space due to iteration performance. SOFC and PD gain is also changed to solve the problem of overshoot. The proposed control strategy is applied to computer simulation of a manipulator and demonstrated the effectiveness of this control strategy.

This study was planned to suggest countermeasure of nutrition education by investigating adolescents, dietary behavior, food weight, and acknowledgement of food calories. 210 middle school boys were selected and asked to fill out the questionnaire. The subjects were divided by nutrition education experience; 1st grade who received nutrition session and 3rd grade who divided subjects. In terms of acknowledgement of food calories subjects nutrition education experience had more recognition for calories than the other group(p<0.01). When one bowl of rice, a potato, a bowel of kimchi and a carrot were asked. However recognition for meats, fishes and eggs were not different between two groups. Among milk and dairy foods the educated group showed high recognition both calories and weight of a piece of cheese than the other(p<0.05). The educated group showed better recognition for calories and weight of tea-spoon of butter, a tea spoon of oil and a tea-spoon of mayonaise, compared to the other group(p<0.01, p<0.05, p<0.05). Also the educated group showed better recognition for calories and weight of a packet of shrimp snack than the other group. The results of this study suggest that nutrition education improved the recognition of calories and weights of foods in study subjects. Also, the number of foods recognized for their calories and weights was higher among subjects who received nutrition education. These results will influence the choice the food by adolescents. Also the nutrition education are thought to be more effective by using photographs or food models, not just by lectures on theories.
