To evaluate risks, complications and mortality of reoperations on heart valve prosthesis, we reviewed clinical records of 53 patients who underwent reoperation because of prosthetic valve failure[PVF], from Jan 1959 through Jun. 1991. They had undergone 48 mitral, 10 aortic valve rereplacement Primary tissue failure was the main cause of reoperation : it occurred in 51 valves at a mean postoperative interval of 58 months. Calcification and collagen disruption of prosthesis were main causes of primary tissue failure in macro and micropathology, In 3 failing mechanical prostheses, paravalvular leak was in 2 cases, another one case had the thrombi at the hinge portion. If conditions such as emergency operation with or without endocarditis, thromboembolism and advanced NYHA functional class are prevented, we think that reoperative valve replacement has similar morbidity and mortality to initial valve replacement surgery. But our sturdy represents higher mortality [22.6%] because of late surgical intervention failing the prevention of conditions leading to myocardial damage. In conclusion if the tearing, calcification, and a new murmur were detected the early reoperation should be considered to increase late survival.

국제기구에서의 전자상거래 논의는 범세계적인 전자상거래 확대를 위한 장애요인의 제거와 전자상거래에 적합한 국제적인 규범 제정 논의이다. 따라서 정부의 역할은 전자상거래에 필요한 최소한의 환경조성에 국한하고 창의적인 민간부문의 주도적인 역할을 강조하는 것이 기본원칙이다. 그러나 상품과 서비스의 국경간 이동에 따르는 통관, 조세, 거래 이행에서의 분규 및 소비자 보호 등 다양한 문제의 발생이 예상된다. 그러므로 이들 문제의 사전 예방 및 사후 처리를 위한 국제적 규범화 작업이 OECD 및 WTO 등 국제기구에서 미국의 주도로 진행되고 있다. 그리고 전자상거래의 발전을 위하여는 전자상거래에 참여하는 민간부문의 자율규제가 바람직하며, 전자상거래가 기존의 거래와 차별을 받지 않고 또한 법적 안전성과 예측가능성을 보장하는 차원에서 법.제도에 의한 정부의 개입이 제한적으로 요구되는 것이 바람직하다. Electronic commerce is creating a new mode of delivering new types of production in a global market. Now, electronic commerce is discussed for dismantling the barriers to global electronic commerce and for establishing the global framework by world organization. Therefore, principles for electronic commerce are minimizing the government polices and emphasizing the creative private roles. But various issues are expected for the electronic commerce, for examples, tariffs, taxation, consumer protection, private protection, intellectual property, and security. So, self-regulatory of private sector is desired for the development of eiectronic commerce. The limited government intervention is only required for securing the distinction of transaction.

The purpose of this study is to investigate the best way that health functional food contributes the diversification of pharmacy management at the new point after the separation of prescribing and dispensing practice. In the question of the number of prescription paper, it was more than 200 papers (18.9%), next 100 papers (11.3%). In case of daily total sales volume except prescription fee, it was more than 1,000,000won (28.3%). About the motivation using health functional food, the reason for activation of pharmacy management was 66%. The selling method was mainly by pharmacist recommendation and consumer's need. In comparison with after and before the separation of prescribing and dispensing, more than 60% of subjects answered that sales volume was decreased and no changed. Concerning the ratio of total sales volume to health functional food within 5 years, 66% of subjects expected that it will be increased positively. The type of best pharmacy to handle health functional food was community pharmacy. These results suggest that the handling of health functional food by pharmacist will greatly increase in near futures and will be very important portion for pharmacy management.
