From 1982 to 1987, six patients underwent left ventricular aneurysmectomy with concomitant myocardial revascularization. Simultaneous repair of postinfarction ventricular septal defect was performed in 3 patients and left ventricular thrombectomy in two. There was no hospital mortality and late mortality during 220 months* follow up period-.[Mean 36.7 months, range 13 to 72 months] Their condition was improved in all. They live in physical condition of NYHA class I-II. We believe early surgical intervention can be life-saving, and can be done without undue surgical risk, even in cases of postinfarction VSD and LV aneurysm with failing heart.

For the treatment of acute respiratory failure and emergency care of an urgent patient, tracheostomy in itself may have been a life saving procedure. But, tracheal stenosis gives serious clinical manifestation which can only be corrected by surgical intervention in many occasions. We experienced one case of tracheal stenosis following tracheostomy for assisted ventilation. Tracheogram showed a 4.0 cm segmental narrowing below the tracheostoma. Before reconstruction, we tried to T-tube cannulation, but the result was not satisfactory. So we resected the narrowed segment and tracheal reconstruction was performed with uneventful result.

본 연구는 가계의 저축운용형태에 따라 가계저축유형을 분류하며 또한 각 저축유형 의 결정요인을 규명하고자 하였다. 분석을 위하여 국민은행이 실시한 1990년도 가계금융이 용실태조사 자료를 이용하였다. 군집분석에 의해 가계저축의 유형을 분류하였으며 가계저축 유형에 대한 결정요인을 찾기 위하여 로짓분석을 사용하였다. 가계적축은 상이한 5개의 유 형으로 분류하였으며 각 유형은 그에 해당하는 가계 저축행태의 특징에 근거하여 수익추구형, 안전지향형, 지역밀착형, 인간관계중시형 및 유비무환형으로 명명하였다. 가계저축유형별 결정요인을 유형에 따라 다소 차이를 보였으나 가계소득, 가구주의 직업, 가구주의 학력이 가장 중요한 결정요인 것으로 나타났다.

많은 선박 사고에서 해상 조난자를 수색 및 구조하는데 매우 많은 시간이 소요되며, 수중에서 체온저하 등으로 적정 시간 내에 구출되지 못한 조난자의 경우 사망 위험이 매우 높은 실정이다. 이러한 위험을 줄이기 위한 기존 기술로는 발광막대, SOS 부이, SART, EPIRB 등이 있으나, 급박한 상황에서 개인이 활용하는 데에는 한계가 있다. 이에 따라, 이러한 문제를 해결하고 효율적인 수색 및 구조 활동을 위한 새로운 방법을 연구하게 되었다.

This paper is seeing as one big cause that reduce Life Time of sensor node become soft if BackOff Time is prolonged in CDMA/CA of competition way that consist at data transmission of each sensor nodes base sensor network environment. So solution method uses GTS, wish to reduce competition Node's, and minimise data transmission delay.

A 6 yers old German Shepherd dog was diagnosed to a ruptured gallbladder subsquently causing a diffuse peritonitis with bile-contaminated ascites. Surgical exploration could not determine its causes of pathogenesis. A marked leukocytosis and increased alkaline phosphotase were the pronounced clinical pathologic features. Delayed surgical exploration was critical therapeutic failure of this particular case. An immediate surgical intervention could be a life saving therapy of choise. The author report an uncommon clinical case presentation of the ruptured gallbladder in a dog and an importance of immediate surgical correction.

There are in many instances emergent cases in traumatic lesions of neck, which require emergency treatment for life saving. The authors experienced a case of multiple lacerations including anterior neck, both forearms and abdomen, that have psychological problems. This is the report of this case along with literature survey.

Recognition of the importance of saving energy and resources compelled us to develop technology for higher efficiency and longer serviceable life. Tribotechnology in recent years evidently reflects this demand. An updated version of a review is made of selected topics of tribotechnology in Japan, which includes high-speed bearings, bearings for office and home appliances, tribology for magnetic recording devices, tribology in architecture and tribo]ogy for automobile.
