Nylon tube를 이용한 대동맥 Prostheses (2례)
윤윤호,정영환,김근호 대한흉부심장혈관외과학회 1970 Journal of Chest Surgery (J Chest Surg) Vol.3 No.1
This is a report on two cases of aortic prostheses using Nylon tube. (Edwards-Tapp A-G Tube, Chemically treated braided Nylon arterial grafts). Especially, the complications after infection of synthetic graft are discussed with reviewing literature. First case was the patient who came to our hospital with rupture of the right femoral artery at the femoral fossa due to pyogenic necrotic process. After femoral arterial prostheses, good pulsation of dorsal artery of foot was obtained. However, the tube was obstructed after 8 weeks postoperatively due tll the complication of infection. In spite of the tube was removed because of obstruction and foreign body reaction of synthetic graft, an amputation of the leg was not necessary for formation of good collateral circulation. Second case was a case of aortic aneurysmal rupture in thoraco-abdominal junction which developed by the trauma of rib resection for osteomyelitis of the left 12th. rib An implantation of aortic graft was performed at the lowest tho13cic aorta by the way of thoraco-abdominal bypass without arterial pump. However, infection produced pyothorax in the left pleural cavity, exposing the tube within the pyothorax. The rupture of the anastomosed upper line occurred in 8 weeks postoperatively and the patient expired.

A clinical investigation was reported on 17 cases of spontaneous pneumothorax requiring surgical mana-gement. Males outnumbered females 15:2. Determination of the etiology in this series showed that the majority were pulmonary tuberculosis and paragonimiasis. Several others had pneumonia, lung abscess, cyst and blebs. It is of particular interest that the acute inflammation of respiratory system was younger age group, pulmonary tuberculosis & paragonimiasis were between 2 nd and 3 rd decades, and lung abscess, cyst, blebs were above 4 th decade. Pulmonary tuberculosis was far advanced bilateral and active. The ratio of right to left side was 13:6 and both side involved in 2 cases. In about half cases of patients, above 50%-collapsed lung associated with mediastinal shifting developed. The complications were pleural effusion and bronchopleural fistula. The former was 13 cases [76.4%] in which 3 cases combined with mixed infection, and latter was 5 cases. As the management, 11 cases were subjected to intercostal or rib resection drainage with continuous suc-tion. Among 11 drainage cases, 8 cases were successful in acute stage and 3 cases failed in chronic stage. This faiure was due to interference with re-expansion of collapsed lung for peel formation and broncho-pleural fistula. The open thoractomy was applied in 9 cases, among which primary operation were 5 cases and drainage failure were 4 cases. Among 11 cases subjected to the open thoracotomy, wedged resection was performed in 3 cases including paragonimiatic cyst, and pneumonectomy in 1 case-tuberculosis, and decortication only was performed in 2 cases in paragonimiasis. Decortication & lung resection was carried out in 2 patients among which ruptured lung abscess 1 case and ruptured multiple blebs 1 case. There was no case of death but prognosis of the tuberculosis may be poor because of far advanced bilateral and active pulmonary tuberculosis.
直射日光의 水面反射遮蔽를 위한 窓計劃에 관한 硏究 : 大邱 地方을 中心으로
韓允昊,金相徹,尹亨洙 嶺南大學校 環境問題硏究所 1990 環境硏究 Vol.9 No.2
窓의 前面에 넓은 수면이 전개되어 있는 경우에 直射日光 뿐만이 아니라 水面에 의한 反射光이 동시에 室內로 사입되어 실내의 熱環境을 열악하게 만들며 수면으로 인한 Glare 현상으로 眺望機能이 극히 악화된다. 따라서 本 稿에서는 建築的 手法을 통한 효율적 조절방법으로서, 遮陽과 발코니를 이용하여 眺望의 기능을 최대한으로 확보하면서 室內過熱의 원인이 되는 直射日光 및 反射光의 遮蔽 방법을 연구하였다. 그 결과를 요약하면 다음과 같다. 1. 水面 反射光은 넓은 발코니를 이용하여 日照環境이 나빠지기 쉬운 向에서도 眺望機能의 큰 손상없이 효율적으로 차폐가 가능하다. 2. 連續窓 계획시 遮陽計劃은 각 陰影角에 변화를 주어 格子遮陽裝置로 개량할 수 있다. 3. 日射遮蔽를 목적으로 계획된 遮陽裝置가 그 차양장치의 陰影마스크 만큼의 기간동안에는 窓을 통한 Glare 현상을 防止할 수 있다. In a case that there is broad water surface in front of windows, not only direct sun beams but also reflected sunbeams get into interior spaces. So indoor thermal environment is ready to spoiled and view from interior spaces through windows could also be impaired because of glare caused by reflected sun beams from water surface. In this paper, as an effective passive control, a method to provide a large solid angle for view through windows and to prevent direct and reflected sun beams with shading devices and balconies is studied. Results are as follows. 1. Planning broad balconies, reflected sun beams from water surface could be prevented effectively without damaging the view through windows. 2. In cases of planning shading devices for horizontally linear windows, eggcrate shading devices could be made by altering shading mask of horizontal and, or vertical shading devices. 3. Although shading devices are designed for covering direct and reflected sun beams from water surface, they could also prevent the glace from sky and water surface during the period of shading masks of shading devices.
