Background: ATS mechanical valve is a recently introduced pyrolytic carbon bileaflet prosthesis. This report is to evaluate the results of hemodynamic and anticoagulant therapy after ATS valve replacement. Material and Method: From May 1995 to October 1998, 53 patients received 65 ATS prosthesis; 38 Mitral(27-33 mm), 27 Aortic(19-25 mm). 2 CABGs and 5 Tricuspid annuloplasty were taken concomitantly. The follow up period was 769 patient-months(mean 16.2$\pm$10.0), varied from 1 month to 39 months with 92.5% follow up rate. All patients were evaluated with Doppler echocardiography, 7-14 days after operation. Result: NYHA functional class was improved significantly, from 2.6$\pm$0.8 preoperatively to 1.3$\pm$0.4 postoperatively. The average value of peak and mean transvalvular pressure gradients were 25.7$\pm$13.5 mmHg, 12.7$\pm$8.3 mmHg in aortic position. In the mitral position, the average values of peak and mean transvalvular pressure gradient and valve area were 5.9$\pm$2.5 mmHg, 3.1$\pm$0.8 mmHg and 2.9$\pm$0.5 $\textrm{cm}^2$, respectively. In the anticoagulant therapy, mean INR was 2.5$\pm$0.6 in mitral valve replacement and 1.9$\pm$0.5 in aortic valve replacement. There was no anticoagulant related complication. During that period, there were 3 hospital death(5.9%) and 1 late death(1.9%). Conclusion: The early clinical results of the ATS heart valve replacement is quite satisfactory, and low target INR reginmen is safe. And long term follow of hemodynamic characteristics is also necessary.

휴대용 공기호흡기 제품은 재난 및 위험 상에서의 구조를 위한 제품으로서, (주)데크는 국내 최초로 핵심기술인 저장용기의 복합재료 기술을 보유하고 있다. 국내외에서도 안전 및 방재에 대한 제품시장이 큰 성장을 하고 있으며, 현재 소방방재제품의 대체수요와 소방법 개정에 따른 공공건물의 신규 시장이 급성장하고 있다. 현재 (주)데크 제품은 소재기술 및 기술개발능력의 우수성에도 불구하고 시장 진입 상 후발주자이고, 통합화된 제품이 국내에 아직 미비하기 때문에 신제품으로서의 성능과 가격가치에 장애요인이 되고 있으며 동시에 제품의 특성을 정확히 파악한 컨트롤조작기기의 인터페이스개발이 필요한 상황이다. The portable respirator is a product for rescue under disaster and hazard while the Dacc Co., Ltd possesses the compound material technology of storage container which is a core technology as the first in our country. Even in foreign countries, the product market on safety and disaster prevention is going through a tremendous growth while the new market of public buildings is rapidly growing followed by replaced demand of fire prevention products and amendment of fire prevention law. Currently, the Dacc Co., Ltd is a later starter according to market penetration despite the excellence of material technology and technological development ability in its products and because the integrated products are still lacking in our country, the performance and price value as new product are becoming obstacles while the situation is that the development of control device interface that has precisely identified the characteristics of product is necessary at the same time.

The autoimrnune chronic hepatitis is a rare cause of chronic liver disease in Korea. A case of autoimmune chronic hepatitis was diagnosed in a 24 year-old female. She was admitted to the hospital due to the pain and swelling of the right parotid gland. Her liver function test had been known to be abnormal also. The liver biopsy was performed for the further evaluation of abnormal liver function. It showed chronic active hepatitis without evidence of viral infection or injury by hepatotoxin. Laborotory test showed hypergammaglobulinemia and autoantibodies. We report this case as a autoimmune chronic hepatitis with literature review. (Korean J Gastroenterol 1995;739 - 743)

It is important to complete the project within the specified time period and the limited budget in the current rapidly changing business environment. It is difficult to predict the cost of the project in early stage because of the large-scale trend. Budget shortfall due to the failure of cost prediction serves as a higher risk of success. Most previous studies to prevent the risk such as budget shortfall have investigated the direct costs. However, research on the overhead costs are insufficient in terms of both quality and quantity. Direct costs are easily computed for each basis of calculation. But overhead costs that include indirect costs except indirect material cost(IMC) are necessary reasonable and efficient management because they are changed in accordance with the rate of overhead costs. In this paper we introduce an analysis method of overhead costs applied for a Space Launch Vehicle R&D Project.
