Ankylosis of the mandible is a serious and most disabling condition. Impairment of speech, difficulty with mastication, poor oral hygience, facial asymmetiry, and mandibular micrognathia invariably result in much physical and psychologic disability, particularly in young children with complete inability to open the mouth. We performed a one stage reconstruction of temporomandibular joint at the same time as performing multiple additional oateotomies to correct the facial asymmetiry. Temporomandibular joint was reconstructed with costchondral graft or interpositional arthroplasty with silastic implant. Breakdown of 36 cases is as follows. 1. Most prevelent incidence is at age of 21-30 revealed no sex predilection. 2. Trauma was the most common cause, found in 8 patients. 3. Average preoperative mouth opening was 21mm and postroperative mouth opening was 39.8mm 27 patients with interincisor lengh greater than 30mm resumed a satisfactory life style with no discomfort. 4. Anethesia was done by fiberoptic nasotracheal intubation in 31 patients. 5. Postroperative complication included infection in 3 patients which was treated with local and systemic antibiotic therapy. 1 patient developed transient lower lip hypoesthesia.1 patient complained remained facial asymmetiry, which was corrected by fat injection. 6. In 20 patients simultaneous total correction of temporomandibular joint ankylosis and facial asymmetry were done.

Epidemiological studies suggest that 30-50% of patients diagnosed with symptomatic congestive heart failure(CHF) have electrocardiographic evidence of a major intraventricular conduction delay, which may worsen left ventricular systolic and diastolic dysfunction through asynchronous ventricular contraction and paradoxical interventricular septal wall motion. Biventricular pacing is an emerging therapy allowing simultaneous electrical stimulation of the both ventricles with an implantable pacing system and it improves hemodynamics and well-being of patient by reducing ventricular asynchrony. Recently, we underwent biventricular DDD pacemaker implantation in a patient with CHF and Left bundle branch block and was significantly improved exercise tolerance and quality of life in that patient.

21세기 지식기반사회는 자기 주도적으로 정보를 처리하고 해석하며 판단하는 능력과 지적 가치를 창조할 수 있는 능력을 길러주는 학교수학 교육을 요구하고 있다. 이에 수학교육과정에 담겨져야 할 수학적 지식의 구조․내용․범위, 지식기반 사회에 적합한 수학과 교수-학습, 평가, 교사역할 등 역시 새로운 관점에서 재조명될 필요가 있으며, 이러한 연구는 학교 현장에 대한 이해에서 출발하고 개인의 필요성과 사회의 요구를 반영한 것이어야 한다. 이에 본 연구에서는 지식기반사회에 대비하기 위한 수학과 교육과정 개발 연구의 기초 단계로 교사, 학생, 학부모를 대상으로 현장 설문 조사를 전국 규모로 실시하였다. 설문 조사는 Goodlad의 학교 교육과정 탐구의 개념적 구도를 바탕으로 한국 교육의 실정을 반영하여 설계되었다. 수학 교육과정 실체의 다양한 국면을 조사하기 위한 설문 내용은 목적 및 목표, 교과내용, 교수-학습방법, 평가, 수학적 지식의 성격, 교육정보화, 교사교육, 사교육, 교육과정일반으로 구성되었다. 본 고에서는 Goodlad의 교육과정 탐구모형과 그 모형에 기초하여 작성된 본 연구의 수학교육과정 탐구모형, 실시된 설문조사의 방법 및 절차를 소개하였고, 설문조사의 주된 결과를 토대로 수학교육과정 개발연구에의 시사점을 찾고자 하였다. This study is to provide suggestions for the development of better mathematics curriculum model of Korea based on a national survey of teachers (527), students (1314), and parents (638). It is our belief that understanding the perceptions and experiences of those involved in the process of teaching and learning of mathematics education needs to be the first priority in any effort to explore better mathematics curriculum model. For the study, Goodlad's conceptual system for curriculum inquiry has been used, but modified to take into account Korean context and the nature of mathematics curriculum. In this paper we introduce the Goodlad's curriculum inquiry model and mathematics curriculum inquiry model based on the Goodlad's conceptual system as well as the survey process. We made few recommendations from the main results of the survey for the research and development of mathematics curriculum model in Korea.

면외변위의 정량적 계측을 위한 ESPI와 Shearography의 비교

최정구,김경석,장호섭,정성욱 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.2

Electronic Speckle Pattern Interfrometry is a common method for measuring out-of-plane displacement and in-plane displacement and applied for vibration analysis and strain/stress analysis. However, ESPI is sensitive to environmental disturbance, which provide the limitation of industrial application. On the other hand, Shearography based on shearing interferometer can directly measure the first derivative of out-of-plane displacement, which is insensitive to vibration disturbance. This paper proposes the out-of-plane displacement extraction technique from results of Shearography by numerical processing and measurement results of ESPI and Shearoraphy are compared quantitatively.

Trauma is one of the most common causes of death. Recently, injury severity score(ISS) is widely used to evaluate and classify the patients with multiple injury. Trauma score(TS) was developed as a means of providing rapid accurate assessment of the injured patient. Authors conducted a review of trauma patients who visited the emergency department of YongDong Severance Hospital from September 1992 to August 1993. ISS and TS were collected from comprehensive initial evaluation. The results were as follows : 1) The subjects were 10.2%(2,666 patients) of total 26,202 emergency patients. 2) Male to female ratio was 2.1 : 1. The age distribution was highest under 10 year(24.9%). The mean ISS was 3.5, and the mean ISS increased with ago. 3. Analysis of injury mechanism showed high incidence of traffic accident(35.3%), blunt trauma 25.7%, fall 24.2%, stabbing 10.7%, and others 4.3% in order. 4. The 8.0% of patients were admitted after initial management and their mean Iss was 12.6 mean TS was 15.5. 5. Among admitted traffic accident patients, the mean ISS of passenger T.A., pedestrian T.A. and driver T.A. were 19.0 ±9.9, 14.4 ±10.6, and 11.3 ±7.7 respectively. 6. Among 42 mortality cases, 25 patients were D.O.A. and 17 were expired. The mean ISS of D.O.A. Patients was 30.0; the mean Iss and mean Iss and mean TS of expired patients were 28.3 and 11.8 respectively. 7. The most common cause of death was head trauma(66.7%). 8. By comparing the ISS and TS of admitted and expired patients, mortality occurred above 16 point of ISS. The mortality increased with increasing ISS, but it was influenced by the trauma site and the severity of the particular injury site. Mortality also occurred below 15 point of TS, the mortality increased inversely with TS, and the mortality with TS, and the mortality was high below 13 point (above 40%).

Seong, Dong-Ook,Lee, Mi-Sook,Park, Jun-Ho,Park, Hyeong-Soon,Park, Chan,Yoo, Kwan-Hee,Yoo, Jae-Soo The Korea Contents Association 2008 International Journal of Contents Vol.4 No.4

With the development of information communication and network technologies, ubiquitous era that supports various services regardless of places and time has been advancing. The development of such technologies has a great influence on educational environments. As a result, e-learning concepts that learners use learning contents in anywhere and anytime have been proposed. The various learning contents authoring systems that consider the e-learning environments have also been developed. However, since most of the existing authoring systems support only PC environments, they are not suitable for various ubiquitous mobile devices. In this paper, we design and implement a contents authoring system based on learning activities for u-learning environments. Our authoring system significantly improves the efficiency for authoring contents and supports various ubiquitous devices as well as PCs.
