A heart supplies bloods of about 15, 000 liters to each human organ in a day. A normal function of heart valves is necessary to this act of heart. The disease of heart valve develops to a narrowness of a closure, resulting in an abnormal circulation of bloods. In an attempt to eliminate the affliction of heart valves, the operation method to repair with artificial heart valves has been developed and saved numerous patients over past 30 years. This replacement operation has been performed since early 1960`s in Korea, but all the artificial heart valves used are imported from abroad with very high costs until recent years. The artificial heart valve using pyrolytic carbon has been developed at KAIST, which was proved to be stable in the mechanical performance and durability. Therefore, the in viva performance of this valve was examined through animal tests. The artificial heart valves used in this study are tilting disc type valves, in which the disc were made of graphite coated with pyrolytic carbon and the cages were made of titanium. In viva testings of these valves were performed in 12 dogs, in which right ventriculo-pulmonary arterial [Croup I] or inter-aortic [Croup IV] valved conduit was implanted using polytetrafluoroethylene conduits containing KAIST valve and aortic valve [Group II] or pulmonary valve [Croup III] was replaced by a KAIST valve with a 21mm or 19mm tissue annulus diameter. In group I and II, pre-and post-operative transvalvular pressure gradient was measured and compared with other prosthetic valves. During post operative period laboratory examination was performed including hemoglobin, hematocrit, red cell count, white cell, lactic acid dehydrogenase and platelet. The eight surviving dogs were sacrificed and autopsy was performed at 2, 6, and 8 weeks. KAIST valve has low transvalvular gradient and relatively high orifice area. Average ventriculo-aortic peak systolic transvalvular gradient was 14 mmHg in 21 mm valve and 19 mmHg in 19 mm valve. The valve has slight intravascular hemolysis effect. Thrombogenic effect of low polishing quality and eddy currents around small orifice is high. The valve has vulnerability of disc movement. These animal tests suggest that the improvement of the heart valve design, surface polishing state and prescription methods.

Apartments have become the most popular type of residential building in Korea since the 1960s. The dwelling space should be designed to accomodate various life styles or changing needs of family members. This research is conducted to analyze flexible interior space types of apartments and to improve the architectural planning and design of apartments that can satisfy various needs of residents. In this study, apartments of 10 - 90 pyeongs built in the region of Seoul, between 1998 and 2007, are investigated in terms of the unit plan, the number of open sides, and a distribution of flexible apartment types for each year, Apartments with flexible space are classified into 10 different types, including a flexible type between bedrooms, a flexible type between a bedroom and the livingroom, and a flexible type between the dinning room and the livingroom. According to the composition of unit plans, apartments are also differentiated as a single-corridor type, a double-corridor type, a stairway type, a hall type, and a combination type. According to these classifications, the characteristics of desirable unit plans were analyzed. The results of the analysis showed that, as the unit size of apartments get bigger, the ratio of width/depth of the front side unit plan is increased. This result reflects a trend of high-rise apartments which have an increased number of front-side bays and a shorter depth for better penetration of daylight. In addition, a hall type is found to have a wider front side and shorter depth. According to open sides, a flexible type of the livingroom and the dinning room/kitchen (L-D.K) is found to be most common for the front/back open space, and the livingroom is usually placed on the front/side open space. To meet the changing needs of residents, more research should be conducted on flexible dwelling space.

In the 1960s, rapid urbanization and industrialization created the social atmosphere of individualism in Korea. Individualism has weakened social ties, led to the breakdown of communities, and caused various social problems. So, the paradigm is shifting to a shared society and there are moves to seek ways to solve social problems through community. As part of the initiative, the value and importance of common space in multi-unit dwelling, the typical Korean housing type, is increasing. Thus, the purpose of this study is to identify the trends of domestic research about common space, to assess the current state of domestic academic world and explore the future plans of the common space. The content analysis method was mainly used and statistics were additionally used to analyze 172 preceding research. As a result, research on common spaces showed a steady increase to the current time. And research was being diversified in the field of publishing journals, research contents, research methods and facilities. Until now, most studies have focused on improvement of plan and the quality of common space by identifying the attitude survey, space planning, and the actual situation. Thus many more studies about proper way to operate and manage common space need to be conducted. it is considered that the common space will develop more efficiently. The study is expected to be used as groundwork for the development of the common space and serve as concrete data to show future development directions.

The importance of trade in services has been increasing day by day, but the research on it is insufficient so far in terms of basic information, statistics, influence, industrialization and so on. To foster of professional trader in services, we need curriculums, textbooks and training centers like academy or college in advance. We have well developed curriculums for trade in goods since 1960's in Korea, so we can transfer the trade in goods' curriculum to trade in services. There are some differences between trade in goods and trade in services basically, but we can borrow a lot of idea from trade in goods in terms of basic framework like international economics, international business and international commercial transactions. This study propose the basic framework for trade in services' curriculum. First, trade in services economics handle the basic concept, statistics, characteristics, theories etc. Second, trade in services business treat the global companies to expand their business to global market, so characteristics of service companies, marketing plan and strategies and so on. Third, international commercial transaction of trade in services concentrate for procedures and contracts in terms of formation, implementation and finish of contract. Finally, Services industries can be a future strategic industry to any contries, so there are some national and corporates' strategy for expanding their business. This study acts on the initial idea for curriculums of trade in services, so I am looking forward to many criticism and development from another researchers to develop the model curriculums and textbook for education of specialized trader in services.

SHOP DWG의 현주소 어디까지 왔는가? 설계에서 제조에 이르는 전 과정을 컴퓨터로 제어하고 관리하는 기술. 캐드(CAD)와 캠(CAM)은 각각 computer-aided design,computer-aided manufacturing의 약칭으로 컴퓨터보조설계와 컴퓨터보조생산을 뜻한다. CAD는 설계도면을 한 장씩 수작업으로 제도하지 않고 설계 데이터베이스의 정보를 CRT(cathode ray tube)에서 화상을 보고 합성하면서 설계하므로 작업을 최적화 할 수 있다. CAD로 설계된 설계도의 내용은 CAM을 통해 NC(수치제어)공작기계에 정확한 작업동작을 지시하게 되며, 작업관리∙가공∙조립∙검사 등의 제조과정을 컴퓨터로 관리하여 작업속도와 제품의 정밀성을 높이게 된다. 최근에는 건축현장의 2D system이 보편화되어 있지만 건축현장의 핵심이라고 할 수 있는 기계설비의 기계실, 또는 조립화 공법 등에는 3차원 CAD∙CAM시스템이 개발되어 입체형상을 화면에 3차원으로 재현할 수 있고, 대상물의 표면적∙부피∙무게∙강도 등의 물리적 성질도 자동 계산하여 최적상태에서 현장의 시공에 적용할 수 있게 되었다. 1960년대 초 미국에서 자동차 모델∙엔진, 항공기 부품 등 의 설계에 수작업의 한계를 느껴 개발되었으며, 한국에서는 70년대 중반에 도입되어 운용되고 있다. 이에 따라 프로그램 회사들은 다양한 방법 등을 SHOP DWG에 적용하여 판매경쟁이 치열하다. (주)우진아이엔에스는 급속한 산업경제의 변화와 무한경쟁시대에 보다 나은 기술개발 투자에도 노력을 기울여, 2000년 11월 용인공장, 생산라인을 천안으로 이전, 확장 하여 배관 및 닥트의 CAD-CAM SYSTEM, P.F.P공법, 기계실3D, 블럭화배관, 닥트자동화 시스템, 설계, 용접공정을 공장화시켰으며, 신 개발품인 S.C.D(SEMI-CON DUCT)를 신설하여 모든 건축물에 맞는 필수적인 제품을 생산함으로써 선택의 폭을 넓히고, 현장 시공능력 효율을 높이고 있다. 이번 호에서는 (주)우진아이엔에스가 95년 설계팀을 발족하여 제로시스템의 3D공법을 공장 및 현장의 SHOP DWG에 적용해왔고 최근에는“서초 프로젝트A”현장에 SHOP DWG의 최대 결집체인 3D활용의 조립화 공법을 적용하여 초고층 오피스텔현장을 시공한 사례를 게재한다. 우진아이엔에스는 30여년의 기술 축척을 바탕으로 최고의 기술력과 풍부한 경험을 통해 아셈무역센타, 타워팰리스1차, 3차 및 목동트라팰리스, 분당트리폴리스, 수원삼성전자 R4, 등 국내굴지의 초고층빌딩 시공을 근거로 초고층의 기본설계를 이해하고 SHOP DWG을 통해서 기계설비공사의 향후 나아갈 지표를 제시하고 있다.

Since the establishment of health centers in the 1960s, the centers have been played an important role in providing basic health care for the people. Although the health centers made a great effect to prevent diseases and promote the health status of the people for the last three decades, the function of health centers should be strengthened to meet the health care need of individual, family and community. Over the last ten years, there have been great changes and developments in health related environments, such as population size and age, rapid urbanization, up-grading of the educational level, increase of income, health care demand for promotive health care measures and practical measures for chronic diseases and also practicing healthy life. According to the great changes in health related environments, the health centers should be reformed. The following policy options are recommended as a summary; First, the function of health centers should be converted from providing basic health services into promotive and preventive health care services, to meet changing needs of people. Second, the health center personnel should be reinforced for their competency to provide a qualitative services to people and also the operation of health center should be reactivated. Third, a close linkage of health centers with the private sector is an essential requirement for the operation of the health care delivery system within a health district in order to improve the health status of people. Fourth, type of manpower mix, scope of organization and health care program should be varied, based on the health care needs of people, geographical characteristics and size of population etc. Fifth, a comprehensive health care delivery system should be developed, for maintaining healthy life style of people and also the health and welfare services should be integrated in order n ensure an effective service.

A substantial literatures on environmental risk perception have emerged since the late 1960s. Most these works focus on how people form risk perception, on what people believe, on difficulties in communicating information about health, safety, or environmental risks to non-experts. In this study, questionnaire surveys were conducted to sample from stakeholders(general public, environmental specialist, governmental official, non-government officials, journalist) during March and Aprils, 2000. Total number of responses was 1,803 including 773 persons of general public, 353 experts, 390 governmental officials, 111 journalists and 176 NGO members. Risk perception on 26 environmental issues were statistically analyzed to relate with the need to regulate each issues, interest and knowledge, experience of hazard, satisfaction in environmental situation, etc. This research aims to aid risk analysis and policy-making by providing a basis for understanding and anticipating group responses to environmental issues and improving the communication of risk information among general public, lay-people, technical experts, and decision-makers. This study concludes that those who are in charge of promoting and regulating health and safety of citizens should understand how people perceive about and respond to environmental risk. Without such understanding, well-intended environmental policies of governments would be ineffective.

Lime-bordeaux mixture (LBM) has been used instead of pesticides in ginseng field and orchard since the 1960's in Korea. In this experiment, LBM was made with different concentrations and sprayed in the field of ginseng for eco-friendly cultivation. Growth characteristics and disease such as alternaria blight, anthracnose, and gray mold were investigated in 4-5 year old ginseng after spraying LBM. LBM caused a little damage on leaf when it was sprayed at the time of leafing stage, late April and early May. Root weights of five-year-old ginseng were 43.1~51.5 g and 41.2~46.6 g in the plot of mid-April and mid-May treatments, respectively. These growth levels were further reduced as compared with that of the chemicals treatment plot. The rate of diseases in the plot of 6-6 and 8-8 ratio were 0.0~4.8% and 0.0~4.4%, respectively, which was similar with that in the plot of chemical control for alternaria blight and anthracnose. However, LBM had little effect on controling gray mold. It showed lower control effect in the plot of 4-4 ratio than that of chemical control. This result will be expected to be a useful guide that can be used in the field to the farmers of the ginseng.
