  • 차대 보행자 교통사고는 발생빈도에 비하여 사망률이 매우 높은 특징이 있다. 전세계적으로 정부 및 보험사에서는 보행자 보호를 위한 새로운 안전기준을 수립 및 강화하는 추세이다. 보행자 보호 성능을 향상시키기 위하여 한국정부는 2007 년부터 신차안전도평가에서 보행자 안전을 평가하고 있다. 보행자 보호 성능은 점진적으로 향상되었으나 여전히 미흡한 상태이다. 전개형 후드 및 보행자 에어백 등으로 구성되어 있는 보행자 보호 시스템은 보행자 보호를 위한 대안이 될 수 있다. 보행자의 머리상해기준값을 감소시키기 위하여 새롭게 정의된 설계방법론을 바탕으로 보행자 에어백 설계 절차를 제안하였다. 제안된 설계방법론을 실용적인 측면에서 검토하였고 보행자 보호 시스템의 제작에 적용이 가능하다.

  • Background: Rib fractures are the most common type of thoracic trauma and cause other complications. We explored the risk factors for pneumonia in patients with multiple rib fractures. Materials and Methods: Four hundred and eighteen patients who visited our hospital with multiple rib fractures between January 2002 and December 2008 were retrospectively reviewed. Chest X-rays and chest computed tomography were used to identify injury severity. Patients with only a single rib fracture or who were transferred to another hospital within 2 days were excluded. Results: There were 327 male patients (78%), and the median age was 53 years. The etiologies of the patients' trauma included traffic accidents in 164 cases (39%), falls in 78 cases (19%), slipping and falling in 90 (22%), pedestrian accidents in 30 (7%), industrial accidents in 41 (10%), and assault in 15 (4%). The median number of rib fractures was 4.8. Pulmonary complications including flail chest (2.3%), lung contusion (22%), hemothorax (62%), pneumothorax (31%), and hemopneumothorax (20%) occurred. Chest tubes were inserted into the thoracic cavity in 216 cases (52%), and the median duration of chest tube insertion was 10.26 days. The Injury Severity Score (ISS) and rib score had a median of 15.27 and 6.9, respectively. Pneumonia occurred in 18 cases (4.3%). Of the total cases, 33% of the cases were managed in the intensive care unit (ICU), and the median duration of stay in the ICU was 7.74 days. Antibiotics were administered in 399 patients (95%) for a median of 10.53 days. Antibiotics were used for more than 6 days in 284 patients (68%). The factors affecting pneumonia in patients with multiple rib fractures in multivariate analysis included age (p=0.004), ISS (p<0.001), and rib score (p=0.038). The use of antibiotics was not associated with the occurrence of pneumonia (p=0.28). In-hospital mortality was 5.3% (n=22). Conclusion: The factors affecting risk of pneumonia in patients with multiple rib fractures included age (p=0.004), ISS (p<0.001), and rib score (p=0.038). Elderly patients with multiple traumas have a high risk of pneumonia and should be treated accordingly.

  • Pedestrian to vehicle traffic accidents show a very high mortality rate compared to the frequency of occurrence. In order to improve the pedestrian protection performance of the vehicle, the korean government added a "pedestrian safety" entry from the year 2007. The performance for pedestrian protection of current vehicles gradually improved compared to the past, but it is still insufficient. It was found that the pedestrian protection performance was very weak, such as the top of the bonnet, the A-pillar and under the front windshield. A application of an active hood and pedestrian protection airbags can be countermeasures for these weak points of pedestrian safety. The active hood and pedestrian protection airbags are designed and manufactured to apply to the top of the hood and to the bottom of the windshield. The manufactured system is equipped in a test vehicle and evaluated based on the Korea New Car Assessment Program(KNCAP) test procedures for the performance of pedestrian safety. As a result, the outstanding effect of pedestrian protection has been achieved by the active hood and the pedestrian protection airbag. The rates of pedestrian injury are reduced by 82.2% and 95.4%, respectively.

  • Purpose: One of the main contributors to proximal fifth metatarsal fracture is ankle inversion and the incidence of recurrence may increase in patients with ankle instability. So, the authors confirmed the patients of proximal fifth metatarsal fracture with ankle instability by checking the history and magnetic resonance imaging (MRI) and assessed the value of MRI as therapeutic prognosis and clinical indicators for prevention of recurrence. Materials and Methods: Patients with proximal fifth metatarsal fractures visited our hospital during recent five years were reviewed. 35 patients with suspected damage by ankle inversion had been identified a history of ankle instability and checked the hindfoot malalignment through hindfoot alignment view and MRI was performed prospectively. The patients was devided to three groups on the location of fracture site and the groups were compared each other. Results: The mean time from injury to checking MRI was 10.7 days. There was no structural abnormality and was no significant difference according to the location of fracture. The patients with history of ankle inversion were 31(88.6%) and the patients with history of chronic or recurrent injury were 22 patients (62.9%). The lesion of MRI related to lateral ankle instability were identified in all patients. Conclusion: This study noted a high incidence of lateral ankle instability that was identified by MRI in the patients of proximal fifth metatarsal fracture. Aggressive treatment for lateral ankle instability should be needed for complications as proximal fifth metatarsal fracture to reduce the recurrence and occurrence.

  • Purpose: Bone contusion is usually treated with conservative therapy for 3 months. Bone contusion around knee and hip joints has been extensively reported on, but there are scant reports on this condition in foot and ankle joints. This study evaluated the nature, characteristics and location of bone contusion around foot and ankle joints to enlighten clinicians on how to better treat this disease entity. Materials and Methods: We classified bone contusion of the 76 patients into three types (102 sites; 47 ankle sprains, 18 traffic accidents, 11 falls) according to the Costa-Paz system with employing magnetic resonance imaging (MRI), and the study then analyzed the common sites and areas of occurrence according to the mechanism of injury and duration of pain after first conducting conservative therapy. Results: Of the 76 patients (102 sites) on the MRI, 43 case (42.2%) for talus, 19 cases for distal tibia, and 12 cases for calcaneus were involved. The classification, according to the Costa-Paz system, was Type I, 51 cases; Type II, 32 cases; and Type III, 19 cases. The duration of pain after conservative treatment was 12.15±2.17 weeks for Type I, 14.5±2.15 weeks for Type II, and 21.0±3.8 weeks for Type III. Conclusion: The most common location of post-traumatic bone contusion around both the foot and ankle is the talus, distal tibia, and calcaneus. The most common type of injury noted on MRI is a diffuse signal with change of the medullary component (Type I), In cases of bone contusion extending to a subjacent articular surface or disruption or depression of the normal contour of the cortical surface (Types II, III), the patients' pain appears to last longer. Thus, it is necessary to consider a longer period of conservative treatment in cases of Types II and III bone contusion because the patients' pain may last longer than 3 months.

  • Childhood injuries are the primary cause of death and disability among children aged 5 to 14. Consistent practice of learned safety behaviors can reduce the occurrence of severe injuries among children. However, safety behavior concern is low among Korean-American children specifically and American children, in general. The objective of the study is to evaluate the impact of an unintentional injury prevention curriculum, Risk Watch among Korean-American children. A quasi-experimental design with a nonequivalent control group was used for the designed of the study. Two intervention and two control Korean schools in Atlanta participated in this study. The intervention consisted of weekly lessons in traffic, bicycle, pedestrian, and fire safety. One hundred and two students completed a pre-test and a post-test. The main outcomes were safety behaviors (seat belt use or helmet use), behavioral intentions, and safety knowledge. Analysis of covariance was used for the statistical analyses. Strong intervention effects were found for increasing knowledge of all safety topics in the intervention group. Additionally, statistically significant intervention effects were detected for increasing seat belt and helmet use, as well as behavioral intentions of wearing a seat belt and wearing a helmet, among pre-kindergarten and kindergarten students. For students in grades 1 and 2, intervention effects were found for increasing helmet use. Among students in grades 3 to 8, the intervention group showed statistically significant increases for seat belt use. Limitations of the study and recommendations for modifying and supporting unintentional injury prevention programs for school children are discussed.

  • 현대사회는 끊임없이 발전하고 있고 그로 인하여 최근 지어지는 건축물들은 다양할 뿐만 아니라 초고층화, 대형화 되고 있다. 이런 현실에서 건축물이 지어지는 건설현장에서는 안전관리 시설의 설치, 안전관리 교육, 근로자들의 인식의 전환 등으로 안전관리가 이루어져야 하지만 그렇지 못한 현실에서 안전사고가 다발하고 있는 건설현장에서의 안전관리 확보를 위하여 현 안전관리 실태와 문제점을 분석하여 현행 안전관리 제도를 살펴보고 분석하고 현행 법규와 안전관리 방법 및 근로자들이 안전에 관한 인식의 문제점이 개선될 필요성이 대두되고 있다. 따라서 현장 안전시설 설치의 법적으로 의무화하는 방법과 건설 감리자에 대한 안전관리 권환 및 책임을 확대시키는 방법, 안전사고 발생시 시공회사 뿐만 아니라 발주자${\cdot}$설계자${\cdot}$감리자${\cdot}$하도급자 등 공사참여자 모두에게 책임을 부여하는 방법, 그리고 현행되고 있는 안전교육의 실효성을 확보하기 위하여 안전관리 교육체계를 개선하는 방법 등의 결론을 제시하였다.

  • 목적: 본 증례 보고는 드물게 보고되고 있는 간질 발작과 동반된 견관절 전방 불안정성에서 발견되는 골병변을 기술하고 고빈도의 재발 요인을 파악하고자 하였다. 대상 및 방법: 저자들은 전간 발작과 동반된 2례의 재발성 전방 탈구를 경험하였으며 본 증례 통하여 일반적인 재발성 견관절 탈구에 준하여 치료하면서 정기적으로 경과를 관찰하였다. 결과: 본 두 증례에서 수술의 경과는 전간 발작의 조절 여부에 따라 경과가 결정됨을 알 수 있었다. 즉 간질 조절이 잘된 환자에서는 안정성을 유지할 수 있었으나 발작이 조절되지 않은 전방 불안정성의 경우 결국 재발성 탈구가 유발되게 되었다. 결론: 전간 발작과 동반된 견관절 불안정성에서 재발 방지를 위해서는 경련 조절이 필수적인 인자임을 인지하게 되었다.

  • The medical records of 69 dogs with history of bite wounds, between 1998 and 2006, were reviewed. Information obtained from these files included the general statistics of the patients (sex, age, breed, weight), season on occurrence of injuries, body areas wounded, therapeutic regime used and mortality rates. Intact male dogs were more frequently bitten. The weight distribution of the bitten population was varied 41% for small, 16% for medium and 17% for large dogs. The highest incidence was in young animals. The distribution of bite wound injuries over the year was recorded with peaks in April (13%), March (12%), August (12%) and September (10%). The common regions of injury were the head (22), fore-limbs (17), hind-limbs (15), abdomen (15), thorax (15) and neck (14). Mortality tends to be increased in cases of thoracic or abdominal injury. The results about the prevalence of bite wounds in Daejeon and Chungnam area are intended to use as a reference data in veterinary practice.
