      • 치조골 파열 환자에서의 골 이식술에 대한 임상적 고찰

        배진오,이동근,민승기 원광대학교 생체재료·매식연구소 1997 원광생체재료·매식 Vol.6 No.2

        Bone grafting in the reconstruction of cleft alveolus has become a stable procedure. It provides a continuous and stable maxillary dental arch, closure of oronasal fistula and bone for tooth eruption and orthodontic treatment. But the time, type and site of bone grafting is still debated. The result of bone grafting in 21 patients were evaluated clinically and radiographically in retrospective study. Marginal bone level was evaluated to age group, cleft width and graft materials. and the incidence of flap dehiscience as a negative factor of success rate were evaluated according to age group, cleft width and graft materials. The following results are obtained : 1. Overall success rate is 86.7% 2. Allogeneic bone graft may be a alternative treatment option as a substitute of autogenous bone graft according to our successful results. 3. Flap dehiscence is an important factor of decreasing success rate and clinically, the tension-free flap design and oral hygien care are very important for prevention.

        하악 시상골 절단술 후 고정 방법에 따른 회귀 성향에 대한 비교 연구

        배진오,이동근,오승환,신기영,장관식 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.2

        Objective : To compare two different methods of rigid fixation in postoperative stability after mandibular setback, Material and Methods : 28 patients with Class III malocclusion were treated by bilateral sagittal split ramus osteotomy(BSSRO) and mandibular setback were selected for this study. Group A(n=14) had the bone segments fixed with monocortical miniplate on the lateral side of the mandibular body and Group B(n=14) had three noncompressive bicortical screw inserted at the genial area through a transcutaneous approach. Cephalograms were taken preoperatively, postoperatively within 1 weeks and at a follow-up period (mean 8.9 months after surgery) and the amount of setback and postoperative change were measured. Results : Postoperative relapse between two groups was minimal in setback of the mandible. Statistical analysis showed no significant difference in postoperative relapse. Conclusion : This study suggests that both methods of skeletal fixation investigated give comparable postoperative stability and their use in mandibular setback appears to be a fairly stable clinical procedure.

        유아교사의 핵심역량에 대한 인식

        배진오 ( Jin Oh Bae ),이연승 ( Yeon Seung Lee ) 한국어린이문학교육학회 2014 어린이문학교육연구 Vol.15 No.1

        본 연구는 유아교사들이 인식하고 있는 현재 핵심역량의 수준은 어떠한가를 알아봄으로써 유아교사의 전문성 신장에 도움을 주는데 목적이 있다. 본 연구의 대상은 부산광역시에 재직 중인 유아교사395명이며, 수집된 자료는 PASW 18.0 프로그램을 이용하여 분석하였다. 연구결과 첫째, 유아교사 핵심역량 수준 전체 평균은 3.51(SD=.47)로 "보통" 보다 높게 나타났다. 둘째, 일반적 특성에 따른 유아교사의 핵심역량 수준은 연령, 담당학급연령, 교육경력에 따라 유의미한 차이가 나타났다. 이러한 연구결과를 토대로 결론을 제시하면 다음과 같다. 유아교사들은 자신의 수준을 "보통"보다는 높게 인식하고 있었으나 충분한 역량을 갖춘 것으로 보기는 어렵기 때문에 역량 수준을 높이기 위한 체계적인 연수프로그램이 마련되어야 한다. 또한 교사의 일반적 특성에 따라 유아교사의 핵심역량 수준이 다르므로 개별 교사의 수준을 고려한 맞춤형 역량 개발 프로그램이 필요하다. 유아교사의 핵심역량의 수준에 대해 조사한 본 연구는 교사 양성, 교사 교육, 교사 평가, 교사 임용 등과 연계하여 다양하게 활용될 수 있을 것이다. The purpose of this research is to be helpful for improving early childhood teacher`s professionalism by examining the current standard of core competency that childhood teachers recognize. The subject of this research was 395 early childhood teachers who are working in Busan. The data were analyzed by Statistics Program, PASW 18.0. The results of this reserch are summed as follows. The first, the general average of early childhood teacher`s core competency was 3.51(SD=.47) which is higher than "common" The second, The standard of early childhood teacher`s core competency by general characteristics showed significant differences by age, class age and educational career. Based on these results, the following conclusions are presented. children teachers recognized their standard as more than "common", but it`s difficult to consider they have sufficient competency. Therefore, systematic training program must be prepared for improving the standard of competency. Also, the standard of early childhood teacher`s core competency is different by teacher`s general characteristics. Therefore competency developing program customized to the standard of individual teacher must be developed. This research which studied on the standard of early childhood teacher`s core competency will be utilized variously in relation to teacher cultivation, teacher education, teacher evaluation, teacher recruitment, etc.

        하악 과두 골절 환자에서 Lag Screw를 이용한 치료시 예후에 관한 임상적 연구

        민승기,이동근,배진오,양희창 大韓顎顔面成形再建外科學會 1997 Maxillofacial Plastic Reconstructive Surgery Vol.19 No.2

        Treatment of condylar fracture is still controversial, but the indication of surgical mangement is increased due to improved fixation methods and surgical techniques. In this article, we report our clinical and radiological results with the use of lag screw osteosyn-thesis for fixation of fractured mandibular condyle. 12 case of condyle fracture treated by open reduction and fixation with lag screw were monitored for an average of 10 months (range from 6 months to 19 months) postoperatively. The obtained results are as follows : 1. Postoperative maximum mouth opening is achieved over 40mm except one patient. 2. Although slight crepitus and deviation of mandible during mouth opening were found, Tempo-romandibular joint problem is satisfactory in all but one patient. 3. Distal migration of screw and resorption of fractured fragment were found in each 2 patients, but good functional recovery was achieved in all. According to the above results, we think that lag screw osteosynthesis is relatively indicated in level III or IV condylar fracture.

      • 개구제한 치료에 있어서 Therabite ^�Jaw Motion Rehabilitation System^TM의 효과

        김수남,이동근,배진오,우승철 원광대학교 생체재료·매식연구소 1996 원광생체재료·매식 Vol.4 No.3

        In oral maxilofacial surgery, limited mouth opening (trismus) is a common symptom resulting from traumatic and postoperative conditions involving the muscles of mastication and their attachments. The limited mandibular function of trismus can result in impaired nutrition, speech, oral hygiene and lifestyle. In the head and neck cancer patient, these symptoms can occur at a time when nutrition, attitude and oral hygiene can be very important to comfort and recovery. Limited jaw mobility can make it difficult to introduce food into the mouth and interferes with the oral preparatory phase of swallowing. Therefore we have to treat the limited mouth opening with various method such as hot pack, muscle massage, muscle stretch with manual, tongue blade and therabite jaw motion rehabilitation system. This study has demonstrated the efficacy of therabite jaw motion rehabilitation for treatment of limited mouth opening in mandibular fracture, internal derangement of TMJ, deep facial infection patients. Ten patients complaining of limited mouth opening were treated by therabite jaw motion rehabilitation system. This treatment was found to be effective in reestablishing normal mouth opening within 4 week in postoperative. It is suggested that therabite jaw motion rehabilitation system is simple, non-invasive, inexpensive, and highly efficient procedure in patients with limited mouth opening.
