左心室-右心房短絡治驗 1 例 : A Case Report
申基雨,崔順浩 圓光大學校 醫科學硏究所 1985 圓光醫科學 Vol.1 No.1
The prevalence of the left ventricular-right atrial shunt has been estimated as slightly less than 1% of all congenital heart diseases, but is being encountered with increasing frequency. The diagnosis is often not suspected on the basis of clinical findings. Frequently the diagnosis is made at the time of cardiac catheterization or is confirm by the selective left ventriculography. Recently, we experienced left ventriclar-right atrial shunt, which was underwent successful surgical repair under the cardioplmonary bypass. The type of left ventriclar-right atrial shunt was supravalvular, which was repaired by direct mattress suture with pledget.

Acute gastric volvulus is one of the most fatal complications of the eventration of diaphragm and require emergency surgical treatment unless it is possible to pass a nasogatric tube. This 10 year old female patient was admitted because of severe abdominal pain and marked abdominal distention before about 3 days. On chest P-A and plain abdomen, there were the elevation of the left hemidiaphragm and marked dilatation of stomach and the triad of symptoms emphasized by Bochdalek in 1904 was present. Emergency operation [wedge resection of necrotic area of stomach and gastropexy after gastric decompression and plication of diaphragm] was performed. The type of gastric volvulus was organo-axial rotation, in which the stomach rotated around the line that connects the cardia with the pylorus [Fig. 4].

Over a period from May, 1977 to SEptember, 1982, 101 cases ofopen heart surgerywere done under cardiopulmonary bypass. There were 50 male and 51 female patients, and the ages of the patients ranged from 19 months to 48 years. Sixty-nine cases were congenital heart disease and 32 cases were acquired heart disease, which consisted of 30 valvular disease, 1 IVC obstruction, and 1 myxoma. Among the 30 cases of valvular disease, 12 MVR, 4 MVR+TAP, 2 MVT+AVR, 1 MAP, and 11 OMC were done. There were 3 operative deaths (17.5%) in 16 MVR, 1 in 2 MVR+AVR, and 1 in 11 OMC. Operative mortality in 69 congenital heart disease was 13.0% ; 3 deaths (6.7%) in 45 acyanotic and 6(25.0%) in 24 cyanotic cases. The overall mortality for 101 cases was 14.8%; 13.0% for congenital and 18.8% for acquired heart disease.

Left ventricular-right atrial [LV-RA] shunt is a relatively uncommon defect but is being encountered with increasing frequency. The diagnosis is often not suspected on the basis of clinical findings and so the specific anatomic diagnosis depends upon the use of selective left ventriculography. Recently we experienced LV-RA shunt associated with PDA, which was underwent successful surgical correction under the cardiopulmonary bypass. On the preoperative diagnosis coexistence of PDA was overlooked and identified at the time of operation. The type of LV-RA shunt was supravalvular, which was closed by direct suture with pledget.
그룹 인증 기법을 이용한 이동 멀티미디어 방송 콘텐츠 사용자 관리 방안
신기우(Shin Ki-Woo),박영훈(Park Young-Hoon),서승우(Seo Seung-Woo) 한국방송·미디어공학회 2010 한국방송공학회 학술발표대회 논문집 Vol.2010 No.11
급증하고 있는 이동 멀티미디어 방송 콘텐츠 서비스의 수요에 발맞추어 이 서비스를 이용하는 사용자들을 효율적으로 관리하는 방안에 대해 관심이 집중되고 있다 . 1991 년 Chaum과 vanHeyst에 의해 소개된 그룹 인증 관리 기법은 익명성의 보장이나, 관리상의 편의로 인해 앞에서 언급된 문제를 해결하는 데 중요한 역할을 할 것으로 예상되었다. 하지만, 이후 소개된 몇개의 그룹 인증 관리 기법들이 실제로는 익명성을 보장하지 못 하거나, 외부 그룹에 의해 악용될 수 있다는 점이 증명되어, 그룹 인증 관리 기법을 실제로 응용하기 이전에 안전성 보장을 위해 요구되는 적합한 기준들을 선정하고 , 이 기준에 부합하는지를 살펴보는 일이 더욱 시급한 문제로 대두되었다. 이에 본 논문은 이동 멀티미디어 방송 콘텐츠 서비스를 이용하는 사용자들을 그룹 인증 기법으로 관리하는 데 있어 , 요구되는 안전성 조건과 이에 적합한 그룹 인증 기법을 소개하고 , 실제로 소개한 그룹 인증 기법이 본 논문에서 선정한 안전성 조건에 부합하는지를 증명하였다. 더불어, 그룹 인증 기법을 실제 효과적으로 응용할 수 있는 비즈니스 모델을 제안하여 그룹 인증기법의 효용 및 앞으로의 개발 방향을 제시하였다.

Over a period from July 1984 to June 1985, 39 cases of open heart surgery were done under cardiopulmonary bypass. There were 23 male and 16 female patients, ranging in age from 18 months to 58 years. Thirty cases were valvular disease. The most common of congenital heart disease is VSD. Among the 9 cases of acquired valvular diseae,1 MAP, 5 MVR, 2 MVR+TAP, and 1 MVR+AVR were done. There were 1 operative death[11%] which was done MVR+TAP. Operative mortality in 30 congenital heart disease was 7%; 1 death [5%] in 22 acyanotic and 1[13%] in 8 cyanotic cases. Finally, overall mortality for 39 cases was 8%; 7% for congenital heart disease and 11% for acquired heart disease.
