This Study has attemped to compare the health care systems of South and North Korea. There has been a wide difference in the health care System between the South and North of Korea. In this paper, I have also shown that each health care system has its own unique response to the social, political, and economic conditions of the country. Therefore the author analyzed and summarized the important difference of health care system between the South and the North of Korea as follows. 1. Compared with the Laissez-faire health care system of South Korea, North Korea has the state socialistic health care system which provide health care services to the people free of charge. And the North Korea is marking positive efforts toward the scientification and systemization of Oriental Medicine which is called Dongui-Hak in the North-on the basis of Ju-Che idea. 2. North Korea's health care system appears to be strongly geared toward extensive and preventive treatment and launched the massive sanitary propagation campaign. which have resulted in a great success. North Korea has a system of universal comprehensive care for its population. The government has a central role in planning and regulating health care. 3. The government also employs physicians, nurses, and other professionals to provide health care to patients at public expense. In North Korea, health professionals are government employees. They work for a salary and the system is funded through general taxation. 4. In the North Korea, health services area system of the cities and countre's unit is strictly conducted along with the doctor's area responsibility system. And so without referal card, patients can not use the upper-grade medical facilities. The health care delivery system of North Korea is made up of the fourth level procedue unlike South Korea. 5. General office of Oriental Medicine, Academy of Oriental Medical Science and Guidance Bureau of Oriental Medicine are established in the organization of the Department of Health in the North Korea. And nowadays much emphasis are equally placed on the Oriental Medicine as well as Western Medicine. Both South and North Korea have faced with a critical moment of developing a mutually agreeable and acceptable system of health care for the unified nation.

During maintenance or construction works in or at the tracks of railways, high risks for passengers and railway staff, especially for the workers on the construction site exist. The high risks result out of the movement of rail vehicles, like trains or construction vehicles, which must be faced by using any available technical and operational technologies for securing them against the environment. Therefore, it is necessary to evaluate the level of protection continuously and to identify new and innovative methods and technologies for the protection of the gang (construction worker, machines and material). Especially on construction sites at line sections with two or more parallel tracks but also with single tracks, there are still a lot of incidents and accidents mostly with seriously injured persons or fatalities. These were mainly gang members that breach the railway-loading gage. By using proper warning or protection systems, the avoidance of such accidents must be achieved. The latest developments. in gang protection systems concern on the one hand fixed barriers in the middle between the construction site and the operated track and on the other hand construction vehicles equipped with automatic warning systems. The disadvantage of such protection methods is that the gang can be warned against an approaching train but a monitoring of the gang members cannot be performed. Only one part of a potential dangerous situation will be detected. If the gang members will overhear the acoustic warning signal of the security staff and the workers will not leave the danger zone in the track, the driver of the approaching train had no chance to react to the dangerous situation. An accident is often inevitable. While the detection of acoustic warning signals by the gang members working on a construction site is very difficult, the acoustical planning of an automatic warning system has to be designed for an acoustic short range level of one meter besides the construction vehicle. The decision about the use of today's technical warning system (fixed systems, automatic warning systems, etc.) must be geared to the technical feasibility and the level of safety which is needed. Criteria for decision guidance to block a track should be developed by danger estimation and economical variables. To realize the actual jurisdiction and to minimize the hazards of railway operations by the use of construction vehicles near the tracks further developments are needed. This means, that the warning systems have to be enhanced to systems for protection, which monitor the realization of the warning signal as a precondition for giving a movement authority to a train. This method can protect against accidents caused by predictable wrongdoing. The actual state of the art technique of using a collective warning combined with additional security staff is no longer acceptable. Therefore, the Institute of Transportation System of the German Aerospace Center in Braunschweig (Germany) will develop a gang warning and protection system based upon imaging methods, with optical sensors such as video in visible and invisible ranges, radar, laser, and other. The advantage of such a system based on the possibility to monitor both the gang itself and the railway-loading gauge either of the parallel track or of the same track still in use. By monitoring both situations, the system will be able to generate a warning message for the approaching train, that there are obstacles in the track, so that the train can be stopped to prevent an accident. And also the gang workers will be warned, while they breach their area.

Objectives : The purpose of this study was to examine the general characteristics, oral health knowledge and oral health behavior of elderly people and the relationship of their oral health knowledge to practice of the knowledge in an attempt to provide information on the development of the senior oral health care system. Methods : The subjects in this study were 324 elderly people who used five different social welfare centers in the regions of Sooncheon and Yeosoo. Results : 1. The oral health knowledge of the elderly people investigated was at a low level. Among different sorts of oral health knowledge, they had the best knowledge on the cause of dental caries, and they were most ignorant about the right time for regular dental checkup. 2. Regarding connections between general characteristics and oral health knowledge, the elderly people who never went to a dentist had a better knowledge on oral health, and those who cared about oral health had a better knowledge than the others who didn't. 3. As to practice of oral health knowledge, the best oral health behavior they did was to clean the tongue during toothbrushing, and oral health behavior was not to have an unbalanced diet. The second best one was to be well-nourished, and the third best one was to refrain from drinking, smoking and eating sugar-containing food. The fourth best one was to get a regular dental check-up and teeth cleaned. 4. There was a positive correlation between oral health knowledge and oral health behavior. A better oral health knowledge led to a better oral health behavior. Conclusions : The better oral health knowledge of the elderly people was followed by a better oral health behavior, and the development and implementation of customized oral health education programs geared toward the elderly are urgently required. Oral health professionals should direct their energy into providing sustainable and systematic oral health education, and institutional measures should be taken to make it happen.

현재 참여정부에서는 지역균형발전을 높은 우선순위의 정책목표로 삼고 이를 위한 다양한 정책수단을 강구하고 있다. '전국이 개성 있게 골고루 잘 사는 사회 건설'을 비전으로 하고 '자립형 지방화'를 전략으로 삼고 있는 정책의 틀은 각 지역의 독자적인 발전을 추구한다는 점에서 긍정적으로 평가되지만, 문화 사회적인 발전보다는 경제적 측면에 치중되어 있다는 점이 지적된다. 이에 따라 정책수단에 있어서도 지역혁신체계나 전략산업, 산업클러스터 등 산업, 기술 경제를 중심으로 제시되어 있다. 이 논문에서는 향후 지역균형발전 정책이 균형발전의 개념을 명확히 설정하고, 기존 정책의 미진한 점을 철저히 평가하며, 지역특성에 맞는 다양하고 신선한 정책을 도출할 것을 제안한다. 아울러 실행성을 도모하도록 하며, 효율적인 추진체계를 마련할 것을 제시한다.

In this paper, we introduce a category of Multi-FNN (Fuzzy-Neural Networks) models, analyze the underlying architectures and propose a comprehensive identification framework. The proposed Multi-FNNs dwell on a concept of fuzzy rule-based FNNs based on HCM clustering and evolutionary fuzzy granulation, and exploit linear inference being treated as a generic inference mechanism. By this nature, this FNN model is geared toward capturing relationships between information granules known as fuzzy sets. The form of the information granules themselves (in particular their distribution and a type of membership function) becomes an important design feature of the FNN model contributing to its structural as well as parametric optimization. The identification environment uses clustering techniques (Hard C - Means, HCM) and exploits genetic optimization as a vehicle of global optimization. The global optimization is augmented by more refined gradient-based learning mechanisms such as standard back-propagation. The HCM algorithm, whose role is to carry out preprocessing of the process data for system modeling, is utilized to determine the structure of Multi-FNNs. The detailed parameters of the Multi-FNN (such as apexes of membership functions, learning rates and momentum coefficients) are adjusted using genetic algorithms. An aggregate performance index with a weighting factor is proposed in order to achieve a sound balance between approximation and generalization (predictive) abilities of the model. To evaluate the performance of the proposed model, two numeric data sets are experimented with. One is the numerical data coming from a description of a certain nonlinear function and the other is NOx emission process data from a gas turbine power plant.

This study was conducted from Sep., 1999. to Nov., 1999. It researched approximately 60 specialized manufacturers who had homepages on the Internet. Of the 60 manufacturers, 20 of them were chosen for the study all of whom had relatively were made homepages that were geared towards sales. 1. Daily Hanboks on the homepages were put in an electronic catalog. They were photographed and well described. Each picture could be enlarged when needed. 2. The Hanbok's were made for men, women and children. There were every couple's Hanboks. The Hanboks used natural material, mixed spinning and chemical textile, which was easily kept and washed. It was intended, as clothes for everyday wear Silk was used for formal clothes. 3. The prices ranged from low-middle to high clothing for everyday life is reasonable and street wear and formal dresses are priced high. The color of the dresses are not vibrant, but natural and light. As Hanboks become more in demand, there will be more choices available. 4. As matter of the sizes shows weakness. In general they use the western size system. The purpose of this study is to show the direction that Hanbok manufacturers may take for the internet sales and for being more active to promote the spread of the dress. This research came to the fellowing conclusion. Even though Hanbok manufacturers operate homepages. it seems that they are not well used. However, many internet shopping malls have been opened and they have put Daily Hanboks into one of their sales categories. The internet malls are getting more active and are expanding more. Therefore the market value of the Hanboks in the future look optimistic. If smaller sized manufacturers of Daily Hanbok's establish cooperative network that have no time and space limit, they can use the strong power of the market as the market development for Daily Hanboks is endless.
