Bronchial Adenomas are rare entity among the primary bronchopulmonary neoplasms. But they have received attention because of debate on their malignant nature, prognosis, and mode of therapy. We have four carcinoids and two cylindromas from Jan. 1972 to Jun. 1983. Operations include two pneumonectomies two lobectomies and one bilobectomy. In one cylindroma, resection was impossible due to its invasion into mediastinum and pericardium. There were no hospital deaths.

Twelve patients underwent surgical correction of total anomalous pulmonary venous connection[TAPVC] between Sep. 1989 and May 1993. There were 9 boys and 3 girls whose ages ranged from 10 days to 17 month [median 1.2 month]. Six patients were less than 1 month of age at operation. The anomalous drainage was supracardiac in 6, cardiac in 2, infracardiac in 2, and mixed in 2. There were 3 early death, and its mortality rate was 25%. There were no operative mortality after Sep. 1991. Age at operation, presence of preoperative pulmonary venous obstruction, preoperative assisted ventilation and type of anomaly did not affect early mortality. Late pulmonary venous obstruction was developed in 4 patients between 1 month to 4 month after operation. Among these patients, 2 were died and one was reoperated and well, and the other one was not operated because of patient`s refusal. We conclude that late pulmonary venous obstruction is fatal and its early detection and correction is important for improving late survival.

During the 3 years through December 1992, 118 cases of coronary bypass graft were performed at Department of Cardiothoracic Surgery, Asan Medical Center. They consisted of 80 males and 38 females with the mean age of 59. History of myocardial infarction was noted in 23 cases[20%], congestive heart failure in 11[10%], left ventricular aneurysm in 6, postinfarct VSD in 2, and mitral regurgitation in 1. The angina was stable in 13 cases, and unstable in 104 cases[89%]. Left main stem disease were 41 cases[35%], triple vessel 36[31%], double vessel 30[26%] and single vessel involvement[LAD] in 10. We performed 335 distal bypasses out of 117 cases, with single bypass in 9, double 29, triple 52, quadruple 23, and quintuple 4. Myocardial protections were cardioplegia in 29 and intermittent aortic occlusion 79 and continuous aortic perfusion 7. The ischemic time per graft was 13 minutes[intermittent aortic occlusion group] and 20 minutes [cardioplegia group] respectively, and the mean number of graft per patient is 2.85. Early mortality was 6.8% [8/117]. If we exclude the patients with LV aneurysm, the surgical mortality could be downed to 4.5% [5/111]. The causes of deaths were cardiogenic shock[6], aortic dissection[1], and neurologic complication[1]. We conclude that noncardioplegic myocardial protection may be equally beneficial or sometimes advantageous to cardioplegic technique in aortocoronary bypass graft surgery.

모바일 컴퓨팅 환경의 발전에 따라, 실시간 문자 중계 서비스나 하이라이트 경기 영상 스트리밍 서비스가 인기를 얻고 있다. 실시간 문자 중계 서비스는 현재의 상황을 요약하여 실시간으로 제공하여 주지만, 전반적인 경기 상황을 제공하지는 못한다. 한편 하이라이트 경기 영상 스트리밍 서비스의 경우 경기 주요 장면을 제공하여 사용자에게 현장감 있는 정보를 제공하여 주지만 실시간으로 제공되지 못한다는 단점이 있다. 본 논문에서는 실시간 문자 중계 서비스와 하이라이트 경기 영상 스트리밍 서비스에 소셜 미디어를 더하여 통합 환경의 서비스를 제공하는 소셜 미디어와 실시간 TV 중계 영상을 활용하는 실시간 스포츠 문자 중계 서비스 시스템을 제안한다. 제안하는 시스템은 모바일 또는 웹 환경에서 문자 중계를 기본으로 하여 소셜 미디어와 TV 중계 영상을 이용한 하이라이트 동영상 서비스와 소셜 미디어 요약 서비스를 함께 제공한다. 또한, 이를 바탕으로 사용자가 원하는 하이라이트 영상들을 선택하여 자신 만의 하이라이트 영상을 저작하는 시스템을 제안한다.
