  • The advancement of medical technology has made it possible to treat various incurable diseases. Especially organ transplantation can give another life to the patients who have organ failure and could not find any other ways to treat their diseases. According to the development of medical technology and immunosuppressive drugs, the rate and extent of organ transplantation is increasing these days. New medical technologies like organ transplantation brought on critical issues and these have changed the way of thinking and morals that has been the fundamental rules in our society. Bioethics is already an important field of medicine and oriental medicine should investigate the problem caused by the development of medical technology and life science and should form a view of life in oriental medicine. Oriental medicine is East Asian traditional medicine based on "Huangdi-Neijing", constructed by the system of Jangfu and meridian. The traditional therapies of oriental medicine have completed a scientific system on the point of view that looks on human and nature equally. This process continued to form a new medical theory as the environment was changed and the new diseases were appeared since "Huangdi-Neijing" and "Shoganron" showed a new scope to investigate human and diseases. Therefore, it is important to develop the point of view of oriental medicine as the medical situation was changed. Oriental medicine has a holistic view that considers human as a little cosmos resonated by a big cosmos and regards the possibility to recover and to regulate the energy in our body. This theory is a basic idea of oriental philosophy. Oriental medicine focuses on the balance of yin and yang of the body and tries to harmonize the imbalance of yin and yang caused by the life style and environment. This can solve many problems that cannot be settled by modern medicine and this can accomplish the new paradigm of oriental medicine that is needed these days.

  • Since the middle of 1990s, in Korea a few researches on the optimal management technologies combining numerical model and GIS for the management of water environment in drinking watershed area and reservoir such as Paldang Lake have been carried out. In this study, the integrated water environment management system was been suggested to efficiently reflect the public awareness of the environment by integrating the web based distributed data collection system, GIS, public hearing system and water quality model. As all the components of the system have been developed using the World Wide Web and all data have been collected from the relevant agencies through the Internet, the water quality model could be implemented on the web directly. In consequence, the environmental geographic information in Paldang Lake could be acquired and analyzed through the Internet. The system can rapidly respond to the public right to know on environment, so the public will willingly participate in the governmental projects on environment. To verify the usability of the developed system, it has been applied to Paldang Lake. Especially when the web based model has been used, users can easily and confidentially get the prediction results by applying the minimum number of parameters for the water quality model. This model will provide clearness and scientific bases in the process of water quality prediction for the sensitive sites where there are critical conflicts between the residents and the developers. In this study, rapid water environment management technique without spatial and time limit has been suggested, which can contribute to the efforts on the government and the public participation.

  • We have witnessed several kinds of new discourses and practices in health and medicine since the 1970s, such as popular concerns with alternative or complementary medicine, inordinate attention to the promotion of 'healthy' living, rapid resurrection of traditional medicine and ecological management of health. Four structural and situational factors are discussed to underlie these new trends:(i) as 'crisis' in health care of the 1970s was translated into health care reform of the 1980s backed up by neo-liberal political philosophy, the state responsibility for nation's health is being transferred to the individual ;(ii) it resulted from the limits of biomedical paradigm in dealing with chronic diseases;(iii) medico-scientific knowledge of disease is transformed into the subjective discourses and technologies of health in postmodern society ; and (iv) it is deeply associated with the considerable increase in environmental risk perception of health and disease. There are some inherent countervailing forces in these new discourses and practices. First, while they derive from lifestyle-oriented behavioral change, medicalization of life and death is still consolidated in the new trends. Second, inasmuch as new tides are reliant upon science, they. are likely to be remote from techne that means not the practical application of theoretical knowing but a special form of practical knowing. Third, as new discourses and activities accomplished'in the name of health'increasingly occupy important strategies in forming the self-identity, they serve as moral apparatus which involves prescriptions about how we should live our lives and conduct our bodies, both individually and collectively. Therefore, two points are suggested to consider seriously whether these streams will succeed in improving the‘healthy’living of all the people. Instead of limiting tile perspective to medicine, healing and health care, a new matrix that interweave welfare, ecology and labor along with them is timely needed for enhancing the health for all. In addition, as the World Health Report fm strongly shows, inequality in health heavily depends upon socio-economic development of a society, and it is not the richest countries that have the best health status, but those that have the smallest income differences between rich and poor.

  • The history of nuclear fusion research in Korea is rather short compared to that of advanced countries. However, since the mid-1990s, at which time the construction of KSTAR was about to commence, fusion research in Korea has been actively carried out in a wide range of areas, from basic plasma physics to fusion reactor design. The flourishing of fusion research partly owes to the fact that industrial technologies in Korea including those related to the nuclear field have been fully matured, with their quality being highly ranked in the world. Successive pivotal programs such as KSTAR and ITER have provided diverse opportunities to address new scientific and technological problems in fusion as well as to draw young researchers into related fields. The frame of the Korean nuclear fusion program is now changing from a small laboratory scale to a large national agenda. Coordinated strategies from different views and a holistic approach are necessary in order to achieve optimal efficiency and effectiveness. Upon this background, the present paper reflects upon the road taken to arrive at this point and looks ahead at the coming future in nuclear fusion research activities in Korea.

  • 이제까지 수행된 우주 탐사 임무에서 임무 궤도의 설계는 행성 혹은 위성과 인공위성의 2체 문제 (two-body problem)에 기초한 Hohmann transfer를 기반으로 하는 Patched Conic Approximation 방식이 주로 사용되어져 왔다. Hohmann transfer는 원 궤도에서 다른 원 궤도로 천이할 수 있는 타원 천이 궤도의 설계 방식으로서, Patched Conic Approximation은 태양계를 여러 개의 2체 문제로 분해하고 각기 분해된 2체 시스템 사이의 Hohmann 천이 궤도를 설계하여 조합함으로써 행성 간의 임무 궤도를 설계하는 방식이다. 이 방식은 하나의 행성만을 고려했을 때, 즉 행성과 인공위성의 2체 문제일 때, 가장 효율적인 천이 방식으로 알려져 있고 현재까지의 우주 탐사 임무 설계에 주로 이용되고 있다. 하지만, 우주 탐사 임무가 점차 다양화되고 소형 위성을 이용한 임무 수행의 필요성이 증가함에 따라 기존의 Patched Conic Approximation은 요구되는 연료의 양이 크다는 점과 원뿔꼴(conic) 특성을 가지는 궤도만을 표현할 수 있다는 점에서 한계점을 보이기 시작하고 있다. 이에 반해 3체 동역학의 기하학적 특성은 기존의 태양계의 패러다임을 획기적으로 변화시킨다. 개념적으로는 요구되는 에너지가 매우 적은 에너지로 태양계를 모두 연결하는 궤도를 구성할 수 있기 때문이다. 본 논문에서는2체문제 기반의 임무 궤도 설계 기술의 한계성에서 벗어나 유연하고 효율적인 탐사 임무를 설계한다.

  • Nanotechnology, one of the technologies that forms the core of the recent scientific innovation, is used much in our real lives. Especially products that use nano silver are being sold, with its positive characteristics resulting from the antibacterial effects of both nano materials and silver. But critiques have pointed out that nano silver diffused into everyday life too quickly as we do not have done any comprehensive research about the material, and worry that nano silver will affect the ecology adversely. Therefore, this research focuses on investigating the toxicity of silver nanoparticles first. To compare the effects of exposure to silver nanoparticles at pre-somite stage and somite stage(10 hours after fertilization), we exposed zebrafish embryos to silver nanoparticles(15, 30 ppt) during embryogenesis, and then checked the details of catalase enzyme activity. The hatch rate decreased in the silver nanoparticles exposed groups(15 and 30 ppt); furthermore, the hatched fishes had an abnormal notochord, damaged eyes and curved tail. The catalase activities of the 15 ppt exposed group at somite stage increased relative to those in the control group. Therefore, the silver nanoparticles could seriously damage the development of zebrafish embryos. Especially, exposure to silver nanoparticles at somite stage did severer damage than exposure since pre-somite stage did.

  • To build a suitable National Health Care System for the coming 21s1 century, Nursing must also be renewed. The future Korea will be united and the majority of its population will raidly consist of the aged. Economically standing on the same level with developed countries the growth of scientific technologies will foster communications, firing astounding changes in the medical field. While the overall life style pattern of Koereans not to mention the structure of diseases undergo change, the possibility that the reckless induction of high-tech health care may only cause medical fees to eascafate. It can전so be expected that the health care system will evolve towards the consumers. Nursing in the 21s1 century will be of two scenarios according to WHO, which presents the role of the nurse. The first scenario is that "a gen-eric health care work force" namely a "care giver" will replace all other health professions. If Nursing does not become the compatent profession fitting to this purpose it will eventually dei out. The second scenario is that nurses who are educated in a well grounded and extensive general background and have command of a specialized area will undertake services varying from health pro-motion to treatment and rehabilitation both direct and indirectly, while supervising other personnel. The nurse here would become the "care giver". To become the necessary health care profession in the 21s1 century, nurses should be provided with more educational opportunities, variating in its con-tents, course, and system, enabling them to grow. Clair Faign points out that the minimal educational entry for the nursing profession is a 4 year undergraduate education in this aspect, now in the time to set the future of Nursing into the course of the first scenario. A new educational system stipulating a baccalaureate nursing degree is in urgent need, and aside from govermental actions nurse themseives should formaily officiallze this process, striving for quality assurance. While considering 6 years nursing education programs, multifarious degree courses for existing 3 years educated nurse should be provided Junior nursing schools must devise measures to grow into baccalaucate institutions, also. Among the existing courses, the Self Study Degree Program should be converted into RN, BSN courese provided by universities, and clinical training for the University on the Air must be supplimented, The possibility of establishing nursing courses into commercial high school programs only jeopardizes the development of the nursing profession.

  • 최근 국 내외 건설 환경은 대형화, 전문화, 다양화되고 있다. 이러한 건설 환경의 변화로 인하여 강구조물 프로젝트의 수요가 점차 증가하고 있으며 강구조물 공사의 효율적 품질관리의 중요성은 더욱 부각되고 있다. 강구조물 공사는 다수의 협력업체와 수많은 공종에 따른 많은 기술력을 요구하는 공사이기 때문에 다양한 리스크와 불확실 요인을 내포하고 있다. 하지만 현재 강구조물 공사의 리스크 대응 및 관리는 과학적이고 체계적 인 방법으로 진행되는 것 보다 공사자의 직감과 경험에 의존한 방법으로 진행되고 있다. 강구조물 공사의 리스크 요인을 파악하고 대응방안을 세우는 것은 강구조물 공사의 품질관리 성패를 좌우한다고 할 수 있다. 따라서 본 연구는 강구조물 공사의 과학적이고, 체계적인 리스크 관리를 위하여 전문가들의 설문조사를 실시하고 계층적 분석법(Analysis Hierarchy Process : 이하 AHP)을 통하여 리스크 중요도와 분석된 리스크 요인의 대응방안을 제시함으로써 강구조물 공사의 품질관리 체계를 정립하고자 한다.
