  • 부속실 단독가압의 제연설비 구역에서 계단실 출입문의 크기 변화가 개방 및 폐쇄조건에 미치는 영향을 분석하기 위해서 자동폐쇄장치의 구조와 저항모멘트의 관계를 정리하였으며, 부속실 출입문의 크기 변화를 고려하여 개방력과 폐쇄력을 측정하였다. 그 결과 부속실 출입문의 크기가 증가할수록 개방 및 폐쇄조건에 도달하기 위한 힘의 크기는 증가하였으며, 폐쇄시간, 회전속도, 회전각도와 힘의 관계, 자동폐쇄장치의 효율을 고려한 부속실 출입문의 설계범위가 존재함을 확인하였다.

  • In Pusan Paik Hospital, Inje University, we experienced 174 cases of pulmonary resections for pulmonary tuberculosis from Jun. 1979 to Feb. 1990. In all of them automatic stapling devices were used for division of lung parenchyme and /or bronchial closure. The results were as follows; l. In 174 cases[male 100, female 74], third and fourth decades were 116 cases [66.7%]. 2. Indications for lung resection in the radiographic findings were destroyed lung 47 cases[27.0%], destroyed lobe 42 cases[24.1%], cavitary lesions 42 cases[24.1%], tuberculoma 22 cases[12.7%], and bronchial lesions 21 cases[12.1%]. 3. The mean of staplers used in the operations was 1.6, and possible stapler-associated complications were only 2 cases of bronchopleural fistula after pneumonectomy. 4. Twenty-seven of 36 patients with bilateral lesions and 52 of unilateral ones on chest X-ray films were AFB positive on preoperative sputum smears. Twenty-three[85.2%] of bilateral lesions and 51[98.1%] of unilateral ones were AFB negative at 6 months after operations. 5. Main complications of resections were operative death 1[0.6%], empyema 4[2.3%], respiratory insufficiency 3[1.7%], pleural dead space 5[2.9%], and bronchial spreading of tuberculosis 2[1.1%]. Bronchopleural fistula were only 2 cases after pneumonectomy and none after lobectomy or segmentectomy. 6. One hundred and forty two patients[92.8%] of 153 with available follow-up data were in the state of good quality of life.
