Living environments in rural area have become deteriorated rapidly. Increase of aging population, decline in agricultural income, polarization of wealth in rural community due to rural returners have caused severe decline and imbalance of living environments in rural area. Responding to this circumstances, governments currently develop projects for improving living environments focusing on individual housing which were excluded from governmental supports because those had been regarded as private property. Nevertheless, there are still some gaps and problems in evaluating the quality of living environment and suggesting effective solutions. It would be because standards and guidelines of the projects have been based on urban housing system. In order to support the implementation of the projects, this research has developed an index for evaluating and monitoring the quality of living environments in rural area. By applying Delphi method, the index has been created in four categories of 'security', 'convenience', 'comfortability', and 'durability' 'Security' consists of structural safety, crime, disaster, accident prevention. 'Convenience' includes three divisions of living, traffic, farm working. 'Comfortability' is divided into sanitation, indoor environments, and aesthetic appreciation. Lastly, 'durability' has four divisions of energy conservation, environmental friendliness, efficiency, and economics. Each sub-division also has different items from three to twelves. In the case of an index for performance evaluation, items have been derived from energy conservation(6-items), and environmental friendliness(7-items). Items developed as an index for evaluating rural living environments in this research might be good background information for remodeling project in rural housing development.

Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intra-abdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.

3색 화살표 신호등(3색 신호등)을 시범 설치하여 운영하던, 2011년 5월 대한민국은 열띤 토론에 휩싸였다. 논란의 핵심은 두 가지로 요약 할 수 있다. 첫째 3색 화살표 신호등이 운전자에게 혼란을 일으켜 교통사고를 유발 할 수 있다는 것이고, 둘째 예산낭비라는 것이었다. 본 연구에서는 이러한 핵심 논란 중, 3색 화살표 신호등이 운전자에게 혼란을 초래하는지에 대해 초점을 맞춰 연구를 수행하였다. 효과척도(MOE)로는 차두시간을 선정하였다. 운전자가 교차로에 진입하면서 혼란스러워 머뭇거리면 출발손실시간과 차두시간에 영향을 주기 때문이다. 따라서 3색 화살표 신호등 설치 전/후 비교분석을 통해 기존 4구 신호등과 차이가 있는지에 대해 분석을 실시하였다. 현장조사는 총 3개 지점에서 실시하였으며, 설치 전/후 비디오 촬영을 통해 정지선을 통과한 차량의 차두시간을 측정하여 각 지점별 설치 전/후 차두시간을 비교분석하였다. 분석결과, 3개 지점 모두 3색 화살표 신호등 설치 전/후에 차두시간은 통계적으로 차이가 없는 것으로 분석되었다.

중피낭종은 드문 종격동질환으로서 주로 우측 심장횡격막 각에서 잘 발생한다. 그러나 드물게는 비전형적인 위치에서 발생하며 특히 후 종격동에서의 발생은 매우 드물다. 교통사고로 내원한 30세 여자환자에서 우연히 심낭과 척추체 사이의 후 종격동에 위치하는 큰 낭종이 발견되었다. 낭종은 장축이 18 cm에 이르는 매우 큰 크기였으며 주로 좌측 흉강 쪽으로 커져 있었으나 환자는 증상을 호소하지 않았다. 반대측 흉강으로의 박리에 어려움이 있어서 작은 수술창을 동반한 비디오흉강경 수술로 완전 절제를 시행하였다. 장기 관찰에서 재발 없이 경과는 양호하였다.

A clinical analysis was performed on 404 cases of the chest trauma who were admitted and treated at department of thoracic and cardiovascular surgery, Chung Ang University, Yong San Hospital during the past 8 years from July 1984 to April 1992. The results were as follows. 1. The sex ratio was 3: 1 with male predominence. 2. The common age groups were 3rd, 4th, 5th and 6th decades. 3. The most common chief complaint was chest pain[58.2%]. 4. Of 404 cases of chest trauma, 50 cases were resulted from penetrating injuries whereas 354 cases were from non penetrating injuries. The most common cause of the non penetrating injuries was traffic accident[234/354, 66.1%] and of the penetrating injuries were stab wound[47/50, 94%]. 5. The left thorax was the preferred site of chest trauma. 6. The range of hospital stay was from less than 1 week to over 6 weeks and the average duration was about 2 weeks. 7. The common chest trauma was rib fracture[51.6%] and others were simple contusion [18.8%], hemothorax[14.6%], hemopneumothorax[14.9%] and pneumothorax[8.7i]. The rib fracture was prevalent between 4th to 9th rib laterally. 8. There were 92 cases of associated injuries which were bone fracture[66/92, 71.7%], head injury[17/92, 18.5%] and abdominal injury[9/92, 9.8%]. 9. The methods of treatment were conservative management[58.6%], closed tho-racostomy[23.3%], open thoracotomy[3.4%] and others. 10. There were 28 cases[6.9%] of complication, such as pneumonia, atelectasis, emp-yema, respiratory failure and others. 11. The overall mortality was 2.5%[10 cases] and causes of death were hypovolemic shock, acute renal failure, adult respiratory distress syndrome, sepsis and multiple organ failure.

During the period of 4 years from August 1, 1975 to August 1, 1979, authors have experienced 100 cases of multiple rib fractures by nonpenetrating injury at Department of Thoracic Surgery, Paik Foundation Hospital in Seoul, Korea. 1. The ratio of male to female patients with multiple rib fracture was 2.6:1 with male predominance and 84% of the total cases were between 20 and 50 years of age. 2. The most common cause of multiple rib fracture was traffic accident and falls accounted for the next largest group. 3. The most common site of rib fracture was 4th rib to 7th rib level on both hemithorax [52%]. 4. Associated injuries were cerebral contusion in 26%, clavicular fracture in 22%, long bone fracture in 22%, pelvic bone fracture in 10%, and scapular fracture in 8%. 5. Early complications and/or result of the multiple rib fractures were lung contusion in 23 cases, subcutaneous emphysema in 21 cases, hemothorax in 21 cases, hemopneumothorax in 6 cases, and flail chest in 12 cases. 6. The flail chests were managed by strapping the chest with adhesive plaster, external traction of flail segment with towel clip, ventilatory assistance for marginal clinical indications, and in cases of complicated with intrathoracic hemorrhage, wire fixation of flail segment through open thoraco-tomy. 7. The principles of therapy for hemothorax and/or pneumothorax were rapid reexpansion of the lungs by thoracentesis [11%] and closed thoracostomy [22%], but open thoracotomy had to be done on 3 cases because of massive bleeding or intrapleural hematoma and diaphragmatic rupture. 8. The over all mortality was 4% [4 among 100 cases] and the cause of all deaths was head injury.

Chest injuries due to blunt trauma often result in severe derangements that lead to death. And we have to diagnose and treat the patients who have blunt chest trauma immediately and appropriately. A clinical analysis was made on 324 cases of chest injury due to blunt trauma experienced at department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyung Hee University during 8-year period from 1972 to 1979. Of 324 patients of blunt chest injuries, there were 189 cases of rib fracture, 121 of hemothorax or/and pneumothorax, 108 of soft tissue injury of the chest wall only, 41 of lung contusion, 24 of flail chest, 13 of scapular fracture, 7 of diaphragmatic rupture and others. The majority of blunt chest injury patients were traffic accident victims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 3rd decade and 4th decade [60%] and 238 patients were male comparing to 86 of female [Male: Female = 3:1 ]. In the patients who have the more number of fractured ribs, the more incidence of intrathoracic injury and intraabdominal organ damage were found. The principal associated injuries were head injury on 58 cases, long bone fractures on 37, skull fractures on 12, pelvic fractures on 10, renal injuries on 6 and intraabdominal organ injuries on 5 patients. The principle of early treatment of chest injury due to blunt trauma were rapid reexpansion of the lung by closed thoracotomy which was indicated on 96 cases, but open thoractomy was necessary on 14 cases because massive bleeding, intrapleural hematoma and/or fibrothorax, or diaphragmatic laceration-On 15 cases who were young and have multiple rib fracture with severe dislocation delayed elective open reduction of the fractured ribs with wire was done on the purpose of preserving normal active life. The over all mortality was 2.8% [9 of 324 cases] due to head injury on 3 cases, massive bleeding on 2,wet lung syndrome, acute renal failure on 1 and septicemia on 1 patient.

Background: Blunt traumatic cardiac rupture is rare. However, such cardiac ruptures carry a high mortality rate. This study reviews our experience treating blunt traumatic cardiac rupture. Methods: This retrospective study included 21 patients who experienced blunt traumatic cardiac rupture from 1999 to 2015. Every patient underwent surgery. Several variables were compared between survivors and fatalities. Results: Sixteen of the 21 patients survived, and 5 (24%) died. No instances of intraoperative mortality occurred. The most common cause of injury was a traffic accident (81%). The right atrium was the most common location of injury (43%). Ten of the 21 patients were suspected to have cardiac tamponade. Significant differences were found in preoperative creatine kinase-myocardial band (CK-MB) levels (p=0.042) and platelet counts (p=0.004) between the survivors and fatalities. The patients who died had higher preoperative Glasgow Coma Scale scores (p=0.007), worse Trauma and Injury Severity Scores (p=0.007), and higher Injury Severity Scores (p=0.004) than those who survived. Conclusion: We found that elevated CK-MB levels, a low platelet count, and multi-organ traumatic injury were prognostic factors predicting poor outcomes of blunt cardiac rupture. If a patient with blunt traumatic cardiac rupture has these factors, clinicians should be especially attentive and respond promptly in order to save the patient's life.
