Using Dong's guider takes the operation time only three to five minutes and attains to high efficancy. This new technique is merely simple and lessens the patient's distress.

文體論的 作品考 : 憑虛의 境遇

이동희 安東敎育大學 1974 論文集 Vol.7 No.1

If we want to see the real visage of Korean modern literature, there is no denying a fact that the procursors of the realism which embraces also naturalism are Dong-In Kim, Sang-Seop Yeom and jin-Keon Hyeon. Strictly speaking, one of them, Jin-Keon Heon, as compared with Dong-In Kim and Sang-Seop Yeom who stand up for a naturalism, is the most representative auther in the meaning of realism. In the consequence of this view, after my study on the analysis of a style with Dung-In Kim's, here my papers in regular sequence, addition to seek after Jin-Keon Hyeon's works on his literary style, intended to search for its character and to dare answer the visage on the other styles of Korean realism.

슬개골 골절의 수술적 치료

김동휘,김정만,고인준 대한골절학회 2004 대한골절학회지 Vol.17 No.4

목적 : 슬개골 골절 치료의 일반적 치료 지침을 얻고자 하였다. 대상 및 방법 : 평균 2.2년간 추적이 가능하였고 내고정을 시행한 23례를 대상으로 하였다. 주 고정 방법은 금속 나사 7례, Dall-Miles' cable을 이용한 환상 강선 고정 14례, 그리고 이들 두 가지 방법의 겸용이 2례였다. 추가 공정으로는 장력대 강선 고정 9례, 부하배분케이블 고정 3례 그리고 이들 두 가지 겸용이 5례였다. 수술 후 고정은 굴곡위로, 가능하면 90°고정을 7일간 시행하였다. 결과 : 전 예에서 유의한 골편 전위 없는 골유합이 이루어졌다. 일 례를 제외한 전 례에서 완전 운동 범위를 얻을 수 있었다. 결론 : 고정 방법의 선택은 골절의 분쇄 정도, 골의 강도, 골절 부위 및 연부 조직의 손상 정도에 따른 개별화가 필요하다. 강력한 고정, 초기 굴곡위 고정과 조기 관절운동으로 좋은 결과를 얻을 수 있었다. Purpose : To establish general guide line in the treatment of the patellar fracture. Materials and Methods : Twenty three patellar fractures followed for 2.2 years in average, treated with internal fixation were evaluated retrospectively. The primary fixations were the metal screw fixation in 7, the Dall-Mlles' cable circumferential fixation in 14 and combination of both methods in 2 cases. The additional fixations were the tension band wiring in 9, the load sharing cable fixation in 3 and combination of both methods in 5 cases. The initial postoperative immobilazation of the knee joint in flexion, preferably 90°, for 7 days was effective to gain full range of motion. Results : Complete union without displacement was achieved in all cases. Full ROM was achieved in all cases except one. Conclusion : The choice of internal fixation need to be individualized according to the level of comminution, bone strength, fracture site and soft tissue damage. A strong internal fixation, initial immobilization in flexion followed by early ROM exercise were important factors to gain good result.

Purpose: To prove the efficacy of locking compression plate (LCP) in proximal humerus fracture. Materials and Methods: Forty four out of 48 patients who had proximal humerus fracture operation with LCP from November, 2004 to June, 2008 and available for follow up for more than 6 months were evaluated. Eighteen cases were male and 26 cases were female with mean age of 56 years (range 29-85 years). Cause of injury was traffic accident in 17 cases, slip down in 20 cases and fall down in 7 cases. Mean interval from injury to operation was 6.8 days (range 2-30 days) and mean operation time was 80. 5 minutes(range 40-130 minutes). Open reduction and internal fixation with LCP using deltopectoral approach was used in all cases. Postoperative clinical evaluation was done using Constant-Murley assessment and bone union and neck-shaft angle was checked using radiographic exam. Results: Bone union was achieved in 41 out of 44 cases at mean interval of 11.2 weeks(range 6-16 weeks). Mean neck-shaft angle was 129.7 degree (range 101-146) with more than 20 degree of angular deformation in 2 cases. For the complication, 2 cases of temporary axillary nerve injury, 1 case of nonunion, 2 case of delayed unions with angulation, 2 case of ankylosis was observed. Conclusion: LCP can prevent reduction loss and minimize soft tissue injury which result in firm fixation and early immobilization. It seem to be very efficient in treating proximal humerus fracture in elderly.

공진효과 및 비선형 마찰이 존재하는 서보 시스템의 μ-제어기 설계에 관한 연구

황인휘,임동진 漢陽大學校 工學技術硏究所 1998 工學技術論文集 Vol.7 No.1

공진 효과와 비선형 마찰은 거의 모든 서보 시스템(servo system)에 존재하며, 이를 무시하고 제어기를 설계한 경우 성능 저하를 초래하거나 전체 시스템이 불안정해지는 등, 제어 시스템의 성능에 큰 영향을 주게 된다. 본 논문에서는 이러한 공진 효과와 비선형 마찰이 존재하는 서보 시스템에 대하여 μ-제어기법을 적용하여 제어기를 설계하는 방법을 제시한다. 정상상태 오차 없이 마찰력을 보상할 수 있는 제어기를 설계하기 위하여 원래의 시스템을 적분기로 확장한다. 이렇게 확장된 시스템에 대하여 μ-제어기 설계 방법을 적용하여 제어기를 설계한다. μ-제어기 설계 방법은 부분적으로 H∞ 제어 방법을 사용하는데 일반적으로 적분형 서보 시스템에 H∞ 제어 방법을 적용한 경우 과도응답 특성이 나빠지므로, 과도응답 특성을 개선하기 위하여 제어기를 2-자유도 구조로 변환한다. 때때로 전체 제어 시스템에서 비선형 마찰과 적분기의 상호작용으로 인하여 리미트 사이클이 발생할 수 있으므로 기술 함수법을 사용하여 리미트 사이클의 존재여부를 확인한다. In the designing servo controllers, the most important problems which should be considered are resonance effects and nonlinear frictions. These problems exist in almost all the servo systems, and sometimes cause difficulties in designing controllers. In this thesis, a controller design procedure with employ μ-control method is proposed for the servo systems with these problems. In order to design a controller which is capable of compensating frictions and ensures no steady-state error, the original system is augmented with an integrator and μ-control method is applied. In the course of μ-control method, H∞ control method is partially used. Since a conventional H∞ control problem for integral type servo systems sometimes presents poor control performance in transient response, a control structure is transformed into 2-degree of freedom structure in order to obtain satisfactory control output in transient response. And, sometimes, there is a possibility of limit cycles due to the interaction between the nonlinear friction and integrator. To check the possibility of limit cycles, describing function method is used.

안선희,안경미,이경원,장보영,안미라,손동석 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.1

It has been reported that for implatns to become osseointegrated, they must heal in the absence of functional loads for 4 to 6 months. The provisional implants were designed to support provisional restorations and to allow for load-free osseointegration of definitive implants, while the was provided with immediate esthetic and function. In addition, the provisional implant protects graft site. Also the provisional implant provides anchorage for orthodontic treatment and reconstructs vertical dimension in edentulous condyle fracture to practice functional therapy. The provisional implant system is a sound and economical method to achieve patient's immediate masticatory and esthetic function. Three cases are presented to document and illustrate the clinical application.

개인화 서비스 프레임워크 : 사용 예

김동희,이재오 한국기술교육대학교 2006 論文集 Vol.12 No.1

현대인들은 타인들과 동일한 서비스 보다는 자신에게 맞추어진 서비스를 제공 받길 원하고 있다. 또한 변화하는 서비스에 개인의 습관이나 스타일을 변경하여 맞추기 보다는 서비스가 개인에게 맞춰 제공되기를 원하고 있다. 이러한 사용자의 요구를 충족시키기 위한 개인화 서비스 개념이 등장하였다. PDA, 셀룰러 폰, 노트북 컴퓨터 등 다양한 이동이 가능한 기기들이 컴퓨팅 환경의 구성 요소로 등장했으며, 그들의 인기는 증가하고 있다. 그러나, 이러한 이동 기기들은 사용할 수 있는 대역폭 및 디스플레이 능력에 있어 한계를 가지고 있다. 이에 본 논문에서는 OPES(Open Pluggable Edge Service) 프레임워크에 인증서버(Authentication Server), 권한부여 서버(Authorization Server), 정책 관리자(Policy Manager) 등을 추가함으로써 개인화 서비스를 제공하기 위한 컨텐츠 변환 프레임워크를 제안하는 동시에 간단한 구현을 통해 이동 기기에서의 개인화 서비스 제공의 예를 보여주고자 한다. 정책 관리자는 사용자 및 네트워크 자원정보를 근거로 룰을 생성하며, OPES 중개자는 사용자가 원하는 서비스 제공을 위해 서비스 응용 호출 시 룰을 이용함으로써 개인화된 서비스를 제공할 수 있다.

境界로 보는 新羅와 渤海의 관계

李東輝 부산경남사학회 2003 역사와 경계 Vol.47 No.-

After the unification of Three nations, there was no political system except Silla in the Korean Peninsula. Silla had expanded its territory into Deokwon(德源) area and had settled its border by building a long wall and a boundary gate for 721-757. After the unification, Silla's advance into the north was active in the northwestern direct. Silla started to advance in 735 and settled its border by building a long wall in 826. Parhae's expansion of territory probably began about 705-713. Parhae widened its sphere of influence to Deokwon area in the east coast under the reign of Daemuye(大武藝) and to the north of Daedong river in northwestern district under the reign of Daeinsu(大仁秀). Both nations settled their borders on the northeastern district in 721 and on the northwestern district in 826 by building long walls and counties and prefectures. I examined side by side their relation centering around their opposition on border, their expansion of territory and negotiations on border, Silla's Road(新羅道).
