Gastric artery bleeding after blunt trauma is rare. In such cases, if vital signs are stable, angiographic embolization may be performed. Although gastric artery embolization is known to be safe due to its anatomical properties, complications may occur. We report a case of gastric necrosis after gastric artery embolization in a patient with blunt abdominal trauma. The 55-year-old male patient was found with gastric arterial bleeding after a traffic accident. His vital signs were stable, and gastric artery embolization was performed. Gastric necrosis was subsequently found, which was treated surgically.

In recent years, due to the occurrence of traffic accidents caused by black ice in winter, the number of personal injuries is increasing rapidly. Black ice is a phenomenon that occurs like a thin layer of ice on the road surface. Accordingly, many developments of heat-generating concrete are being developed to remove ice by increasing the temperature by supplying constant electricity to places where black ice is likely to occur. These heating elements are being developed by mixing a conductive material represented by carbon nanotubes with concrete. However, research up to now has been focused on efficient temperature rise and derivation of the optimum mixing ratio, and the evaluation of maintaining heat generation performance during continuous repetition is insufficient. Therefore, in this study, a heating test specimen was manufactured and 50V power was repeatedly supplied to evaluate the heating characteristics.

Epiphyseal dislocations and fractures frequently occur in children and adolescents. However, these injuries seldom involve the distal femur, and bilateral cases are even rarer. We present an unusual case of bilateral epiphyseal detachment of the femur in a 21-year-old man who was involved in a traffic accident. Open reduction and fixation surgery were performed 5 days after the incident. The patient experienced favorable progress, with consolidation occurring at 3 months. No lower limb length discrepancies were observed at the 20-month follow-up. In summary, bilateral distal femoral epiphyseal detachment is an uncommon condition that can be effectively treated through surgical intervention.

서론 : 급성 전방 십자 인대 파열이 있는 환자에서 동반된 반월상 연골 손상의 발생 빈도, 위치, 형태 및 치료에 대해 분석하고자 하였다. 대상 및 방법 : 1997년 3월부터 2002년 2월까지 수상 6개월 이내의 급성 전방 십자 인대 파열이 있는 환자 73례를 대상으로 하였다. 남자가 66례, 여자가 7례였으며, 평균 연령은 33($16\~62$세)였다. 수상 원인으로서는 스포츠 손상(45례), 교통사고(19례)순으로 많았으며, 스포츠 손상에서는 축구 손상이 34례로 가장 높은 비율을 차지하였다. 모든 환자들은 관절경을 이용하여 반월상 연골 손상의 위치, 형태에 대해 확인하였으며 치료에 대해서도 분석해 보았고 특히 축구 손상으로 인한 군과 교통 사고로 인한 군에 대해서 비교 분석하였다. 결과 : 급성 전방 십자 인대 파열이 있는 환자에서 반월상 연골 손상이 동반된 경우는 48례$(65.8\%)$로 그 중에서 외측 반월상 연골 손상이 26례$(54.2\%)$로 가장 많았으며, 위치는 후각부에서 52례$(91.2\%)$로 가장 흔하였다 형태는 방사상 파열이 15례$(26.3\%)$로 가장 흔하였으며 치료는 부분 절제술이 38례$(66.7\%)$ 가장 많았다. 이들 중 축구 손상으로 인한 군에서는 반월상 연골 손상이 동반된 경우는 28례$(82.4\%)$였으며, 그 중에서 외측 반월상 연골 손상이 17례$(60.7\%)$로 가장 많았으며, 위치는 후각부에서 30례$(90.9\%)$로 가장 흔하였다. 형태는 방사상 파열이 9례$(27.3\%)$로 가장 흔하였으며 치료는 부분 절제술이 22례$(66.7\%)$로 가장 많았다. 결론 : 급성 전방 십자 인대의 파열시 외측 반월상 연골 손상의 빈도가 내측 반월상 연골 빈도보다 많았으며 후각부 손상이 가장 흔하였다. 본 연구의 결과로 급성 전방 십자 인대 파열이 있는 환자에서 동반된 반월상 연골 손상의 진단과 치료에 도움이 되리라 생각된다.

This study was aimed at furnishing the data of Naso-orbito-ethmoidal fractures and aiding treatmenting Naso-orbito-ethmoidal fractures A 5-year review of Naso-orbito-ethmoidal fractures and concomitant injuries is presented. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wankwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The results were as followes: Male predominated over female by a ratio of 4.6 : 1. The most common reasons is traffic accident(88.2%). The elapsed time from injury to operation is average 9.2 days, and the mean admission days were 79 days and removal of plates were average 217.3 days. The most associated facial bone fractures is Zygomatico-Maxillary complex fracture(20%). Associated injuries were neurologic injury(29.4%), orthopedic injury(23.5%), opthalmologic injury(17.6%), body injury(5.8%), neuropsychologic injury(5.8%) and otolaryngologic injury(5.8%) in this order. The most injured teeth were upper and lower incisors. The intubation methods for surgery were orotracheal(29.57%), submental(29.5%), and nasotracheal technique(41%). Most patients had complications, that were post-traumatic telecanthus, nasal depression, scar formation. This results suggest that early diagnosis and treatment is prerequisits to satisfactory result. Aggressive management of NOE fracture with direct or bicoronal exposure with aid of CT is now an accepted norm.

To investigate epidermiologic trend in maxillofacial fractures. We retrospectively studied 934 patients with maxillofacial fractures between $1981{\sim}1987$ and $1995{\sim}1999$. The results were compared in the previous group (Group A, patients treated between $1981{\sim}1987$) with those in the recent group (Group B, $1995{\sim}1999$). Also, we studied 516 patient between $1995{\sim}1999$ for occupation, associated injuries, treatment and complications. The sex ratio of men to women decreased (5.6 : 1 in Group A vs. 3.5 : 1 in Group B), and the largest age group was 20 to 29 years. There was the highest incidence in September and Fall. The most frequent cause of maxillofacial fracture in both Group A and B was traffic accidents. The distribution of fracture site did not change appreciably, but the frequency of midfacial fracture increased. In the recent group, the largest occupational group was salaried men, and the largest associated injuries of maxillofacial fracture was head and neck injury. Open reduction was used in 91% of the cases, and post-operation complications were infection, neurologic problem, malocclusion, and mouth opening limitation etc. Our results suggest that the clinical features of patients with maxillofacial fractures have changed during the past decade.

집중강우에 의해 주로 발생되는 절토사면 붕괴는 인적, 물적 피해를 초래한다. 한국건설기술연구원은 예방 수단으로서 위험사면을 집중관리하고 있다. 지속적인 사면관리에도 불구하고 지구환경의 변화로 절토사면의 붕괴발생 빈도는 점차적으로 증가하고 있다. 이에 대책공법 적용이 어려운 절토사면에 대하여 상시계측시스템을 설치하고 있다. 상시계측시스템의 운용은 대인 대물 피해에 대한 조치로서 활용될 수 있으나, 강우시 절토사면의 붕괴 징후를 인지하더라도 관리자가 현장관리 작업을 수행함에 있어서 시공간적 제약으로 인한 한계가 있다. 낙석신호등은 상시계측시스템을 통하여 사면 위험 징후가 발견될 시, 도로이용자에게 낙석발생에 대한 위험을 주지시키고, 붕괴시 도로관리자의 현장 도착 전까지 자동적으로 또는 수동적으로 도로를 차단시킴으로서 사면붕괴에 의한 피해를 예방하는 관리시스템의 일종이다.

The fracture and fracture-dislocation of the neck of the talus (Hawkins' type I-IV) are uncommon injuries and represent only 0.12 to 0.32% of all fracures. Authors clinically evaluated in 12 cases Whom treated fracures of the neck of the talus, at department of orthopaedic surgery, Sun General Hospital, from 1990 to 1996, and the following results are obtained. 1. Of 12 cases, there were 11 males and 1 female, average age was 30 years. 2. Causes of fracture was fall down injury in 7 cases(58%), traffic accident in 4 cases(33%), direct trauma in 1 case(8%). 3. According to the classification by Hawkins' type I in 2 cases(17%), type II in 7cases (58%), type III in 3cases(25%). 4. Associated injuries were calcaneal fracture in 3 cases, fracture-dislocation of talus in 3 cases, subtalar dislocation in 3 cases, medial malleolar fracture in 5 cases, soft tissue injury in 3 cases, femur and tibia fracture in 1 case, and lumbar Spine compression fracture in 1 case. 5. Average time to operation after injury was 2.5 days. 6. In 2 cases were treated conservatively and 10 cases were treated open reduction and internal fixation with screw or K-wire. 7. Complications were avascular necrosis in 4 cases, post traumatic arthritis in 2 cases, skin necrosis in 4 cases, and then ankle fusion was done in 2 cases. 8. High rate of complication was seen in the talar neck fracture associated with calcaneal fracture. In the analysis of above results, evaluated by Hawkins' scoring system were excellent to fair in 75%.
