TG Osseotite 임플란트의 성공률에 대한 임상적 연구
오승환,민승기,채영원,Oh, Sung-Hwan,Min, Seung-Ki,Chae, Young-Won 대한악안면성형재건외과학회 2005 Maxillofacial Plastic Reconstructive Surgery Vol.27 No.1
The purpose of this study is to review the prognosis of the TG Osseotite implant(3i Co, USA) placed in partial edentulous area of oral cavity and to suspect the possible causes leading to failure. 124 TG Osseotite implants that had been inserted between 2000 - 2002 were followed up for 2 years(avg : 9.5 months) in function. Medical records, and radiographs were evaluated and analyzed by the over all success rate, gender and age factor, general disease, implant fixture length and diameter, implant site, bone density, and various surgical methods. Chi square test was used statistically. Of the 124 TG Osseotite implants, 9 implants(7.3%) were removed in early phase and 3 implants(2.4%) were in late phase. The cumulative survival rate was 90.2%. The failure of the TG Osseotite implant was closely related with the use of bone graft techniques such as sinus elevation or immediate implantation and not with the age, sex, general disease, implant site, bone density of implanted site. The failure of the TG Osseotite implant was well developed when it was the wide type of implant and it was inserted for single tooth replacement. The developement of peri-implantitis was the most important factor in the failure of the TG Osseotite implant.

직무도전성이 학습민첩성을 매개로 주관적 경력성공에 미치는 영향
심지현(JiHyun Shim),채영원(YoungWon Chae) 한국자료분석학회 2023 Journal of the Korean Data Analysis Society Vol.25 No.2
본 연구는 최근 경제사회적 변화로 인해 경력이 개인중심으로 바뀌면서 주관적 경력성공에 대한 관심이 높아지고 있다. 주관적 경력성공의 다양한 선행요인을 밝히기 위해 본 연구를 수행하였으며, 이와 함께 직무도전성과 학습민첩성을 함께 분석하였다. 3개의 변수를 통합적으로 분석한 실증연구가 부족한 상황에서 각 변수들의 개념적 특성을 바탕으로 이론적 관계를 가정하여 연구모델을 설정하였다. 가설 검증을 위해, 국내 기업을 대상으로 진행한 설문에서 수집한 248개의 자료를 분석하였다. 신뢰도분석, 상관관계분석, 가설검증을 위한 위계적 회귀분석과 매개효과분석을 통한 Sobel test를 수행하였다. 분석결과 직무도전성은 학습민첩성과 주관적 경력성공에 통계적으로 유의한 정(+)의 영향을 주는 것으로 나타났다. 또한 직무도전성은 학습민첩성을 매개로 주관적 경력성공에 통계적으로 유의한 정(+)의 영향을 주는 것으로 나타났다. 본 연구에서 다뤄진 변수에 대한 실증연구가 부족한 상황에서, 분석결과를 바탕으로 개인의 주관적 경력성공을 높이기 위해, 기업차원에서 도전적인 직무를 구성하는 것의 필요성과 학습민첩성을 높일 수 있는 조직의 분위기와 교육의 필요성 등을 실무적 시사점으로 제시하였다. This study analyzed job challenge and learning agility together to reveal various antecedent factors of subjective career success, which increased interest as careers changed to individuals due to recent economic and social changes. In a situation where empirical studies that analyzed three variables integrally are insufficient, a theoretical relationship was assumed based on the conceptual characteristics of each variable. 248 data collected in a survey conducted on domestic companies were analyzed. Along with reliability analysis and correlation analysis, hierarchical regression analysis was performed for hypothesis verification. In addition, Sobel test was performed for mediating effect analysis. As a result of the analysis, job challenges had a significant positive (+) effect on learning agility and subjective career success. In addition, job challenges was found to have a statistically significant positive (+) effect on subjective career success through learning agility. Based on the analysis results, the necessity of constructing challenging jobs at the corporate level, the atmosphere of the organization that can increase learning agility, and the necessity of education were presented as practical implications.

The management of mandibular condyle fractures continues to be a subject of much debate. It is suggested that, if not properly managed, these fractures may give rise to serious problems, such as malocclusion, mouth opening limitation, temporomandibular joint disorders. Treatment planing of mandibular condyle fractures is very important. The aim of this present study was to evaluate the long-term results according to treatment methods in condylar fractures. Also, it was to evaluate results of treatment according to condylar fracture level. We conducted a retrospective analysis of 43 mandibular condyle fractures. 43 patients followed for average period of 9.00 years(mini. 7yr, max. 12yr). All patients underwent a clinical and radiologic evaluation focusing on mouth opening, mandibular movements, TMJ function, change of ramal height, condylar remodelling. If the level of fracture was positioned in high, especially in level II, mandibular movement disability and ramus length loss was more prominent. This results were similar to the cases of treatment of fragment removal. In high level fracture and fragment removal cases, It is thought that more intensive and long term management are needed than other treatment cases using different operation methods. Also, direct fixation by each approach showed good results in mandibular movement, ramal height change and condylar shape. Through this results, accurate reduction of the mandibular condyle fractures was a very important factor in postoperative prognosis.
