South Korea is not a wasteland of publicly funded health care-instead, it has a good medical social security system known as the national health insurance (NHI). The NHI of Korea has three unique features; (1) low premiums, low insurance fees, and low coverage; (2) obligatory designation of medical institutions; (3) and allowance of non-benefit services. These features have made hospitals and doctors interested in profit-seeking. However, the commercialization of medical institutions has taken place in both private- and public-established sectors. A basic problem of commercialization is the co-existence of the obligatory designation of medical institutions and non-benefit services. The problem became worse in the Kim Dae-Jung government because it officially permitted non-benefit services. Since 2000, the Korean government has consistently pursued benefit extension policies, but the coverage rates of the NHI have stagnated. In addition, premiums and current medical expenses have markedly increased because policy-makers have emphasized accessibility to the NHI, while ignoring important principles of medical social security such as a needs-based approach and patient-referral system. In order to resolve the commercialization problem, the obligatory designation of medical institutions to the NHI should be changed to a contract system, and non-benefit services should be prohibited at NHI institutions. We must re-establish the patient-referral system via a needs-based approach. We also need to build a primary healthcare system and public health policies. We should make a long-term plan for healthcare reform.

The Purpose of this study is to consolidate the management status of Saggoson in the Choson period by literature research, and examined latest status by field investigation. During the Choson period, there were fish distributors such as Saggoson and Kakju. Saggoson took charge of fish distribution from the fishing ground to the land, and handed over the fish to Kakju who sold over them to the whole country: This distibution system of fish was started from and adapted to the yellow-corvenia fishery of Westhern Sea. There were two resons far this. One was that these fish were. caught much from vast fishing grounds and had a very strong demand, for which professional disributors were needed. The thor was that because fishermen had very limited capital, they had to supply the money for fish production from capitalists like Kakju whom they agreed to sell fish directly to. By this time, it was thought that the fish distibution system for the Westhern Sea fishery was determined by the background and tradition. Meanwile, Saggoson, which has been working far a long time in Westhern Sea, is placed in changing circumstances. That is, small scale fishery Saggoson deals with will be getting fewer, because the big scale reclamation projects in this area threatens the fishery's existence. Also, Saggoson, presently, might be forced to become more efficient in its distribution in the future. In this situation, the management status of a Sggoson in the past and present needs to be consolidated and investigated through this study.

In this paper, the visual tracking system for arbitrary shaped moving object is proposed. The established tracking system can be divided into model based method that needs previous model for target object and image based method that uses image feature. In the model based method, the reliable tracking is possible, but simplification of the shape is necessary and the application is restricted to definite target mod el. On the other hand, in the image based method, the process speed can be increased, but the shape information is lost and the tracking system is sensitive to image noise. The proposed tracking system is composed of the extraction process that recognizes the existence of moving object and tracking process that extracts dynamic characteristics and shape information of the target objects. Specially, active contour model is used to effectively track the object that is undergoing shape change. In initializatio n process of the contour model, the semi-automatic operation can be avoided and the convergence speed of the contour can be increased by the proposed effective initialization method. Also, for the efficient solution of the correspondence problem in multiple objects tracking, the variation function that uses the variation of position structure in image frame and snake energy level is proposed. In order to verify the validity and effectiveness of the proposed tracking system, real time tracking experiment for multiple moving objects is implemented.

Purpose: The purposes of this study were to examine the level of anger, anger expression, depression, psychosomatic symptom and perceived health status, and to identify the influencing factors of anger expression in shelter residents. Methods: This study employed a descriptive correlational design. Data were collected from 407 homeless people residing at 27 shelters using structured instrument. Results: The level of anger expression was different by age, educational level, existence of children, and duration of shelter residency. Anger expression was significantly correlated with depression, psychosomatic symptoms and perceived health status. The predictors of high-level anger expression was younger age, low educational level, duration of shelter residency in Model 1 (F=6.884, p<.001, Adj. $R^2=.065$, and depression and psychosomatic symptoms in Model 2 (F=7.197, p<.001, Adj. $R^2=.113$. Conclusion: This study suggested that the homeless in the shelters had various psychological vulnerabilities, and therefore more individualized programs based on their needs and psychological health status should be provided for the homeless.

One of the historical origins of the modern science education was investigated in this paper. From the view point of the pansophistic educational philosophy which emphasized "man should teach completely all things to all mankind(Omnes, Omnia, omnino)", J.A.Comenius proposed in his book "Didactica magna"(1658) that 'physica' should be learned as one of the most important school subjects. He suggested the completion of human being as a wholeness of the universe could be achieved through the physics teaching. His ideas of science education was, however, directed not to the 'rational konwledge' about the natural world, but to the 'divine wisdom'. His main thoughts and influences on science education can be summarized as follows: 1) The human being as a God's image should know the divinely created nature, because the invisible God's existence can be sensorially recognized in the nature. 2) Physics or science should be regarded as more important objects than verbal learning in general school education. 3) The cognitive union between the words('representative' or 'das Dargestellte') and things('presentative' or 'das Dargebotene') can be achieved through the objects lesson ('Anschauungsunterricht') 4) The realistic and sensor-cognitive learning theory of the object lesson is yet very important especially in the science education of elementary school, even though the inquiry learning process has became more important in the last years. 5) The religious aspect of his idea could not satisfy the social needs of industrialization and the development of professonal technics in the 18 to 19th century.
