From January 1989 to December 1993, cardiac catheterization and open heart surgery for ventricular septal defect closure were performed in 115 pediatric patients who were selected as meeting the criteria for elective closure of restrictive ventricular septal defect. These criteria included age greater than 1 year and less than 15 years, no evidence of congestive heart failure, Qp/Qs 2.0, pulmonary artery systolic pressure 35mmHg, and no associated cardiac anomalies. Mean age of patients was 5.25$\pm$ 3.53, and 72 patients were male, 43 patients were female[male:female=1.9:1 . Mean systolic pulmonary artery pressure was 19.66$\pm$4.79mmHg, and mean pulmonary to systemic flow ratio was 1.27$\pm$ 0.28. Aortic cusp prolapse was present in 30 patients [26% , aortic insufficiency was present in 1 paient, and 1 patient had prior bacterial endocarditis. There were no instances of complete atrioventricular dissociation, reoperations for bleeding, or reoperations for recurrent ventricular septal defect, but wound infection was present in 1 patient, and there were 7 patients who had the hemodynamically insignificant remnant shunt. There were no early or late deaths or major morbidity.

To determine the role of mediastinoscopy in the preoperative staging of the primary lung cancer, we studied 23 patients from January 1993 to December 1993 and compared the results of mediastinoscopy and computed tomographic scanning with the findings at thoracotomy. Mediastinoscopy was performed in 14 patients when they had larger than 10mm mediastinal nodes at computed tomographic scanning. Six of them were found to have metastatic nodes. Nine patients, who had negative computed tomographic scanning and negative mediastinoscopic results,underwent thoracotomy. One of them was found to have a metastatic mediastinal lymph node. When results from both series of patients were compared, the sensitivity and specificity of computed tomographic scanning showed 83.3% and 47.1% respectively with an accuracy of 56.5%. The results of mediastinoscopy showed that the sensitivity was 85.7%, the specificity was 100% and the accuracy was 95.7%.Because of the low accuracy rate of computed tomographic scanning, a more routine use of mediastinoscopy seems to be justified.

본 논문에서는 서울시 본청 공무원 531명을 설문조사하여 조직효과성에 미치는 영향요인을 분석하였다. 연구모형은 리더십요인(변혁적리더십, 거래적 리더십), 개인적요인(교육훈련, 직무만족), 환경적요인(시민사회의 감시와 비판, 참여와 거버넌스)을 독립변수로 하고 조직몰입을 매개변수로 하여 종속변수인 조직효과성에 미치는 영향력을 검증하였다. 분석의 결과 서울시 실·국·본부장들의 리더십은 조직몰입과 조직효과성에 모두 영향을 미치는데 특히 거래적 리더십의 영향이 큰 것으로 나타났다. 다른 요인들도 대부분 조직몰입과 조직효과성에 영향을 미치지만 교육훈련과 환경적요인들은 영향을 미치지 못하거나 그 영향력이 매우 미약한 것으로 나타났으며, 연구 결과에 따라 서울시 본청 행정조직의 조직효과성을 높이기 위한 대안으로 실·국·본부장들의 거래적 리더십을 강화하기 위한 임파워먼트와 교육훈련과 직무만족도의 개선 그리고 시민사회와의 교류와 협력 확대를 제시하였다. The purpose of this paper is to find out the influencing factors on organizational effectiveness of SMG headquarter organization. To find out the factors, this study carried out a survey targeting 531 SMG Headquarter employees. The analysis model of this study is composed of the 6 independent variables, a parameter and a subordinate variable. The 6 independent variables are transformational leadership, transactional leadership, training, job satisfaction, civil societies monitoring and criticism, and their participation and governance. A parameter is the organizational commitment. And the subordinate variable is organizational effectiveness. The results of statistical analysis shows the transactional leadership influences both organizational commitment and effectiveness much more than that of transformational leadership. Other variables such as job satisfaction, civil societies participation and governance are found out as the influencing factors on organizational effectiveness and commitment of SMG headquarter organization. Training and civil societies monitoring and criticism do not influence on that of SMG headquarter organization. To improve the organizational effectiveness of SMG headquarter organization, this paper suggested SMG first, empower management class officials above the 3th grade for enhancement their transactional leadership, second, upgrade the training system and job satisfaction, and third, expand exchanges and cooperation with civil societies.
