The identity crisis of preventive medicine appears to have been deepening. As a solution, it is insisted that preventive medicine should focus on clinical preventive medicine. However, in the field of heath policy and management, the better solution should be found in a serious search for visions and perspectives of its study on population and society. In this regard, the specialist who studies the field can be defined as a medical doctor majoring in public health. In this paper, I first forecasted major socioeconomic changes to occur in medical and public health arena and explored the role of those studying health policy and management. Secondly, I summarized their career paths and main activities in order to establish visions. Finally, I proposed curriculums on health policy and management for medical school undergraduates and for specialists majoring in preventive medicine, respectively.

Hydrogen, as a future energy source, is thought as an alternative of fossil fuel in view of environment and energy security. Hydrogen has the properties of both fuel and electricity so that it can make the energy paradigm shift in the future. Therefore, researches on hydrogen in power system area are essential and urgent due to their huge effects on current paradigm. In this paper, the visions and technical challenges of hydrogen in power system are reviewed as energy storage, dispersed generation (DG), DC generator, and combined heat and power (CHP).

This study investigated the use of community information and communication technologies in light of its dual visions (i.e., serving as an affordable Internet service provider and a community building tool). Surveying the randomly selected users of a community network (n = 213), this study examined the influence of the community features on service use compared to that of Internet features. The present study found that the respondents were using the service mainly for general Internet features, such as email and web access. More than two-thirds of the respondents did not recognize community contents as available service. Community features of the service were found as significant predictors of use only among people who were aware of community contents but not among people who were not. Nonetheless, there was no difference in the amount of use between the two groups, indicating that the awareness of community contents itself did not increase use. Findings suggest that the service providers did not fully communicate the community aspect of the service with the users although the very aspect distinguishes the service from other Internet services.

In this paper, we propose a system that is configured with double stereo-visions to measure jaw movement. This new system measures not only left and right hinge points of jaw motion but also floating paths of hinge points during lateral and protrusive movement. The resulting 3D position and path data can also be used for 3D graphic simulation technique for occlusion diagnosis and therapy. The system also considers the compatibility with conventional occlusion therapy devices.

Purpose: This study shows a changing tendency of Japanese psychiatric hospitals, presenting "Visions in Reform of Mental Health and Medical Welfare", changed to "Hospitalized Medical Treatment to Living in the Community" and reducing the number of beds since 2004. Methods: This study uses a documentary survey, especially Jananese "Visions in Reform of Mental Health and Medical Welfare System" and a field survey on hospital built for early treatment and return to society after 2004. Results: Change tendencies of psychiatric hospitals are 1) diversification of isolation room and ward, 2) cluster of patient's room, 3) phased organization of space, 4)individualization. Implication: This study will be an important data for researching plan of Korea psychiatric hospital which needs to change by global tendency.
