An embolus is a blood clot or other foreign material in a vessel located distal to the place of origin of the clot or foreign material. Arterial embolectomy, designed to restore patency of an acute occluded vessel has great advance since Fogarty balloon catheter was introduced in 1963. At present, in spite of all these advances responsible for the current higher rate of limb salvage, limb loss and mortality rate are still high in a certain group of patient, and concept of arterial embolism and its management are still undergoing changes. Twenty one cases of arterial thromboembolism, which were seen during the periods of 4 years and 7 months from January 1983 to July 1987 at Chonnam National University Hospital, were studied and divided into two groups, good prognosis group and poor prognosis group according to the absence or presence of death and limb loss, and the prognostic factors were evaluated. The results were as follows; 1) The arterial embolism was most frequently seen in 5th decade in good prognosis group (41.6%) and 7th decade in poor prognosis group (44.5%). Male: female ratio were 8:4 in good prognosis group and 8:1 in poor prognosis group. 2) In good prognosis group, no identified diseases were seen in most cases (7 cases: 58.3%) and atherosclerotic heart disease was most common in poor prognosis group (4 cases:44,4%). 3) The most common clinical manifestation was pain in both groups. 4) Time interval from onset of symptoms to treatment; Within 1 day was most common in good prognosis group (5 cases; 41.7%) and over 1 month was most common in poor prognosis group (6 cases: 66.7%). 5) The most common site of embolism was femoral artery in both groups. 6) Operations were done in 15 cases, among them, 9 cases were good prognosis and 6 cases were poor prognosis. Most common anesthesia was local anesthesia in both groups. 7) The operative mortality was 20%.

As modern society becomes very complex, there has been steady increase in violence, and antomobile and industrial accidents. This has resulted in the increased incidence of facial injures including mandible fracture. We have analyzed 270 such cases from May, 1986 through May, 1996 at the Department of Plastic and Reconstructive Surgery, Chosun university Hospital. Anatomic classification of mandibular fractures is not standardized, we propose a fracture classification that combines several preexisting schemes and takes into account inherent areas of strength and weakness in the mandible. The role of dentition, in particular the canine and third molar teeth, and their relation to fracture patterns is assessed. 1. Ratio of incidence between male and female was 4:1. 2. The Most common age group was the 3rd decade. 3. The Most common cause was the automobile accident (53.3%) 4. Regional frequencies of mandibular fracture were : symphysis (41.9%), angle (21.5%), condyle (18.8%) body (13.3%), ramus (1.7%), coronoid process (1.7%) and alveolus (1.1%) 5. The Most common associated injury was other facial bone fracture(23.3%) 6. The Most common complication was postoperative wound infection (3%) 7. There were more simple fractures (67.4%) than multiple fractures (32.6%), which are on the increase.

The aims of this research is to analyze the middle school students consciousness about folk dance. This research analyzed the answers of 820 students, consisted of 410 boys and 410 girls, to the several questions. The results are followed. 1. Students are generally ignorant of folk dance because of the lackness of edecation in school, and students wants to learn folk dance so as to make school life more enjoyable. 2. The ones who teach students folk dance in school are in order as followers : a class teacher, a physical teacher, and a dance teacher. The motive of students learning folk dance is to participate in a sports meeting in elementary school. 3. The answers on how much facilities they have to do folk dance are in order as follows : Dissatisfied, Satisfied, and Insensible. In general boys want a gymnasium and girls want dancing room to satisfy their wants to folk dance. With an analysis on provincial middle school students consciousness of folk dance I suggest some methods which can increase the needs that students have to folk dance. 1. To understand what real folk dance is students must to be more educated in school. 2. The education of ones who can teach us folk dance from early stage of our life must be reinforced. 3. More facilities in which we can enjoy folk dance must be built

고속 비행체 공기흡입관 설계에는 유체-열-구조 다분야 통합설계의 한 개의 부분으로 비행체 엔진흡입관 구조에 대하여 설계/해석을 수행하였다. CATIA 3 차원 모델에서 PATRAN 으로 상세 평판 구조형상 모델을 생성하여 NASTRAN 으로 강도 및 강성을 만족하는 평판 두께를 정의하는 구조설계와 함께 구조해석을 수행하였다. 공력 GRID 로 표시된 공력과 온도 데이터는 FSI 코드를 이용 구조 GRID 데이터로 변환된다. 구조에는 고온이 작용함으로 내열재, 단열재, 냉각장치 등을 함께 적용하여 고온에서 강도를 만족하는 구조물을 설계하였다. 구조물에 작용하는 온도는 단열 및 냉각장치를 포함하는 시편 모델을 생성/계산하여 구조 GRID 에 입력하였다. 온도가 매우 높은 전반부는 내열재료를 사용하고 비교적 높지 않은 중반이 후 부분은 고강도 철 합금 재료를 사용하여 설계할 수 있었다. As one of MDO of fluid, heat and structure for high supersonic vehicle design, the simultaneous design and analysis of vehicle engine inlet structure was performed. The overall solid configuration was come from CATIA Model, the detail plate model was made by PATRAN and the structural design and analysis were performed by NASTRAN with the definition of the plate thickness to meet the requirements of strength and stiffness. The air-load and temperature input data were from aerodynamic team at the aerodynamic GRID and the loads were transformed to structural GRID by FSI(Fluid Structure Interaction). Since the applied temperature is too high, the heat-resistance material, insulating material and cooling device are used together to meet the strength requirement. The applied structural temperature of the plate were calculated with the specimen model and the temperature distributions were input to the FEM model.

Congenital arteriovenous malformations are abnormal communications between the arterial and venous system, These lesions are the result of faulty development of blood vessels. Their extenaive manifestations create occasional disgnostic and frequent therapeutic problems, their pathologic and clinical characteristics are not widely known. During the periods between 1989.1.1 and 1995.6.30, we experienced 12 cases of congenital arteriovenous malformations and we evaluated various clinical features of the cases, and the results were as follows; 1) The range of age was 6 years to 52 years and 6 cases(50%) of the patients were between 2nd and 3rd decade and the rate of male to female 7:5. 2) The duration between appearance of first lesion and medical examination was less than 1 year in 6 cases(50%). 3) The frequent symptoms and signs were pain and tenderness(50%), pulsating mass(41.7 %), skin discolorization(33.3%) and swelling,limb hypertrophy(25.0%) as in the order. 4) The location of AVM were in lower extrimity (50.0%), face(25.0%), upper extrimity(16.7), pelvic cavity(8,3%) 5) The combined theraphy of embolization and feeding artery ligation and exision were performed in 4 cases(36.4%), the excision in 3 cases(36.4%), the exision and feeding artery ligation in 2 cases(18.2%), the embolization only in 1 case(9.1%), the amputation due to necrosis at admission in 1 case(9.l%). 6) In localized type, complete excision was done in 5 of 8 cases.But in diffuse type, therapeutic intervention was impossible. In conclusion, good results are achieved in sharply localized lesions with sugical approach. But manegement of diffuse lesions should be carefully planned.
