Duodenal web is an uncommon lesion that infrequently cause partial or complete intestinal obstruction. If the duonenal web is incomplete and only partially obstructs the duodenal lumen, the onset of symptoms may be delayed for years, and obstructive symptoms will be only minimal and intermittent. Congenital duodenal obstruction is occasionally associated with intestinal malrotation. We experienced a case of duodenal web associated with intestinal malrotation in a 9-year-old girl who had been suffered from intermittent projectile vomiting since birth without failure to thrive. The diagnosis was made by UGI series & abdominal CT. Patient remained asymptomatic after operation.

폐쇄형 SNS란 카페 블로그 등 온라인 상의 커뮤니티 서비스를 모바일로 옮겨 놓은 것이다. 이메일 주소나 전화번호로 연결된 모든 지인을 일괄적으로 친구로 등록하는 개방형 SNS와 달리, 친밀도에 따라 지인을 따로 관리할 수 있다. 개방형 SNS에 비해 가입자 폭은 넓지 않지만 이용자 충성도가 높다는 게 큰 장점으로 꼽힌다. 이에 본 논문에서는 폐쇄형 SNS를 통하여 학교에서 리더를 맡고있는 회장, 학회장 등에게 효과적으로 학생회를 운영 할 수 있는 어플리 케이션을 제공한다. 이를 통해 사용자들은 효과적인 학과 운영과 질높은 행사, 투명한 학회비 관리 등을 제공받을 수 있다.

Congenital duodenal obstruction in the newborn infant may be due to a variety of causes. Duodenal obstruction often presents with bilious vomiting and upper abdominal distention. Diagnosis is usually established on plain x-ray of the abdomen by the classic finding of the double-bubble. In the period July 1986 to June 1990, 16 patients with congenital duodenal obstruction were operated and the following results were obtained. 1. Sixteen patients were comprised of 11 males and 5 females, the ratio of male and female was 2.2:1. 2. Thirteen patients(81%) had been admitted to our hospital during one month of life. 3. Congenital duodenal obstruction was in 16 cases; malrotation in eight(50%), annular pancreas in six(38%), type 1 atresia in one(6%), and wind-sock anomaly in one(6%). 4. There were two premature patients and six patients of small for gestational age. 5. Overall, bilious vomiting, occurring in three fourths, was the single most frequent presenting complaint. 6. Polyhydramnios occurred in two of the patients. 7. Diagnosis was possible with clinical symptom and simple abdomen. 8. The operative procedures performed were ; duodenoduodenostomy in five, duodenojejunostomy in two, excision of wind-sock membrane in one, and Ladd's procedure in eight. 9. A total of ten asociated congenital anomalies were found in six patients. 10. Postoperative complications occurred in five cases(31%).

Nonocclusive mesenteric ischemia (NOMI) is a rare complication that occurs in about 0.05% of patients after openheart surgery, and NOMI refers to the mesenteric ischemia that's caused by splanchnic vasospasm without occlusion of the great intestinal vessels. In the presently reported case, NOMI developed to maintain the blood flow to the heart and brain after several minutes of a hypotensive status and the latter was caused by acute aortic dissection that complicated an aortic cannulation procedure. Unfortunately, the patient died even though the problems were diagnosed early and proper treatment was administered. Early diagnosis of NOMI by angiography and the selective infusion of vasodilators are thought to be the only way to improve survival for patients with clinically suspected NOMI.

천해역의 파랑발달에 대한 태풍경로의 영향력을 분석 하였다. 우리나라 남동해안에 주로 피해를 초래할 것으로 판단되는 태풍의 경로를 '남해안 상륙 후 내륙 통과'와 '대한해협통과'로 분류하고 각 경로에 따른 태풍규모와 파랑발달을 1956년 부터 2004년까지의 기상자료를 바탕으로 검토하였다. 태풍 경로의 영향력 분석은 천해역 파랑발달의 주요외력이 지형조건에 의해 결정되므로(즉, 폐쇄해역은 태풍의 바람장이 주요외력이며, 개방해역은 심해 전달파랑과 바람장의 영향을 동시에 받는다), 개방해역과 폐쇄해역의 경우로 나누어 수치모형실험을 통해 수행하였다. 실험조건은 태풍 "매미"의 강도와 특성 값을 기준으로 하였으며, 대상해역은 부산신항 인근해역과 원전항 인근해역을 개방형과 폐쇄형 해역으로 대별하여 실험을 수행하였다. 자료의 분석결과 최근 이상기후현상으로 태풍의 강도가 커지고 있음을 뒷받침 하는 근거는 찾아보기 힘들었으며, 2000년대 이후로 남해안에 상륙하는 경로'1'이 대한해협을 통과하는 경로(경로'2')보다 그 내습빈도가 커지고 있음을 볼 수 있었다. 태풍의 경로와 풍향이 같은 방향인 경로'1'일 때 에너지가 집중되어 태풍중심기압과 풍속과 파고의 증가가 함께 일어난다. 그러나 태풍의 경로와 풍속의 방향이 일치하지 않는 경로'2'의 경우는 에너지가 분산되므로 태풍중심기압과 풍속은 함께 증가하나 파랑에너지는 함께 발달하지 않는 것으로 보였다. 내습한 태풍의 강도를 경로별로 비교한 결과, 경로'1'이 경로'2'보다 큰 강도를 가지고 연악역에 영향을 미치는 것으로 판단되었다.

For study on the unsteady wall interference effect, flows around a circular cylinder in closed test-section wind tunnels have been numerically investigated by solving compressible Navier-Stokes equations. The numerical scheme is based on a node-based finite-volume method with the Roe's flux-difference splitting and an implicit time-integration method coupled with dual time-step sub-iteration. The computed results showed that the unsteady pressure gradient over the cylinder is enhanced by the wall interference, and as a result the fluctuations of lift and drag are augmented. The drag is further increased because of the lower base pressure. The vortex shedding frequency is also increased by the wall interference. The pressure on the test section wall shows the harmonics having the shedding frequency contained in the wall effect.

Ileal atresia, a subtype of intestinal atresia, is one of the well-recognized causes of bowel obstruction in newborns. Prenatal diagnosis of intestinal atresia is very important in its management and outcome. Unfortunately, there are few cases of ileal atresia diagnosed prenatally, so more appropriate diagnoses and management plans are needed. As an associated gastrointestinal malformation with ileal atresia, hypertrophic pyloric stenosis is rarely reported. We report one case of postnatally diagnosed ileal atresia associated with hypertrophic pyloric stenosis which was complicated initially by bowel perforation and later by vomiting due to pyloric obstruction. Vomiting in the postoperative period is a common problem. But, if vomiting continues after the operation for ileal atresia, hypertrophic pyloric stenosis should be considered as a possible cause of medically retractable non-bilious vomiting.
