In a patient with blunt abdominal trauma with small bowel injury, early diagnosis is clinically challenging due to unclear clinical symptoms and signs in the early stage of an injury. On the other hand, a delay of diagnosis of bowel disruption may lead to increased complication and mortality. The diagnostic laparoscopy is very useful for the evaluation of the small bowel injury. Laparoscopy can reduce unnecessary open surgery in a patient with blunt abdominal trauma with subtle symptoms and imprecise findings on abdominal computed tomography. Also it can prevent delay of treatment and be converted immediately to open surgery as soon as bowel damage is revealed. Furthermore, extracorporeal repair of small bowel via mini-laparotomy after a single incision diagnostic laparoscopy in a patient with traumatic small bowel perforation was a feasible and safe alternative to conventional laparoscopy. We are pleased to introduce successfully treated cases by extracorporeal repair of small bowel via mini-laparotomy after a single incision diagnostic laparoscopy in a patient with small bowel perforation after blunt trauma.

Duodenal injury following blunt abdominal trauma is a relatively unusual complication, and it may sometimes be difficult to distinguish a duodenal hematoma from duodenal perforation. According to recent reports, intramural hematomas typically resolve spontaneously with conservative treatment. Surgery, however, is occasionally necessary in some cases if the diagnosis is delayed, conservative therapy fails, or a high degree of suspicion of duodenal injury persists. We experienced a case of delayed manifestation of a duodenal intramural hematoma that was surgically treated.

Pseudocysts of lung by blunt chest trauma are rare lesion with 1 to 2 % incidence. The symptoms are nonspecific and misled or confused with lung abscess or congenital cystic disease of lung occasionally. Diagnosis is not difficult by radiographic findings and history of blunt chest trauma. There courses are benign and spontaneously absorbed and require no specific treatment mostly. Recently, we had the one case of 8 year-old female with traumatic lung cyst and its cavities filled the entire right lower lobe. The destruction of lung was severe, so, right lower lobectomy was done and recovered, discharged without event.

A design optimization of Sphere-Cone blunt nose hypersonic flight vehicle has been studied by using upwind Navier-Stokes method and numerical optimization method. Heat transfer coefficient and drag coefficient are selected as objective function or design constraint. Control points of Bezier curve are considered as design variable.

흉부둔상에 의한 심막기종은 매우 드물다. 교통사고에 의해 응급실로 내원한 환자로 초기 흉부단순 촬영에서는 발견되지 않았으나, 흉부단층촬영상 좌측 기흉과 함께 심막기종이 발견되어 좌측 흉막에 관을 삽입한 후 해결된 경우가 있어 보고한다.

A tracheo-esophageal fistula following from blunt chest trauma is one of less common lesion and few guidelines are available to direct its optimal management. Herein, we report a 24-year-old man injured in a motor vehicular accident sustained a nonpenetrating double blowout injury of the thorax and large tracheoesophageal fistula occurred. Tracheal defect required resection and reconstruction, of which the membranous portion underwent closure with borrowed adjacent esophageal wall primarily and substernal left colon interposition was performed 4 weeks later.

We have experienced 21 cases of traumatic diaphragm injury between October, 1989 and September, 1993. Of these patients, 17 cases were caused by blunt trauma and 4 by penetrating injury. Among 17 blunt traumas, 10 cases developed at left side, 6 at right and 1 at central subpericardial diaphragm, and among penetrating injuries, 3 cases developed at right side and 1 at left. Overall mortality rate was 21% and one due to blunt trauma was 29%. Initial hypotension was a predisposing factor to presume future death. When associated injuries involved 4 or more organs, mortality rate was high.

We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

Myocardial infarction (MI) secondary to coronary artery fistula and the subsequent occlusion of the distal right coronary artery (RCA) after blunt chest trauma is a rare entity. Here, we describe a case of coronary artery fistula and occlusion with an inferior MI that occurred following blunt chest trauma. At the initial visit to the emergency room after a car accident, this patient had been undiagnosed with acute myocardial infarction, readmitted five months after ischemic insult, and revealed to have experienced MI due to RCA-right atrial fistula and occlusion of the distal RCA. He underwent coronary surgery and recovered without complications.

A design optimization of hypersonic flight vehicle has been studied by using upwind Navier-Stokes method and numerical optimization method. CFD method is linked to numerical optimization method by using a Bezier curve and a design optimization of blunt nose hypersonic flight vehicle has been studied. Heat transfer coefficient and drag coefficient are selected as objective functions or design constraints. The Bezier curve-based shape function was applied to blunt body shape.
