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.

Objectives: his study was performed to examine whether a community organization strategy had been driven by core values explicit in Ottawa Charter and to give some suggestions for using values in health promotion practice in Korea. Methods: We searched literature online with key words of 'values', 'health promotion', and/or 'Ottawa Charter', etc, and reviewed published papers on design, implementation, and evaluation of Health Plus Happiness Plus Projects in Gyeongsangnam-Do, a community organization strategy. Results: Evident core values since Ottawa Charter had been holistic definition of health, empowerment, community participation, addressing the impact of broader determinants of health, reducing social inequities and injustice, and intersectoral collaboration. A community organization strategy was good at realization of most values. Some ways for value-driven health promotion practice were suggested. Conclusions: More discussion and debate on values in health promotion are needed in Korea.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated services requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with the service diversification.

The purpose of this research is to introduce the best practice of the Japanese national dementia strategy and explore implications to the Korean national dementia strategy. Interview was conducted among professions those who is in charge of Kumamoto dementia care practice in Kumamoto province, upon review of related literature and public documents. The Kumamoto model is implemented by the department of neuropsychiatry in public university hospitals, which can offer dementia-specialized medical services. Medical centers for dementia in public university hospitals play a leading role for managing practice and training local dementia centers specialist, coordinating medical services among medical institutions and community welfare facilities. In reference to the Kumamoto model, the Korean national dementia strategy can find implications in the direction of current system, specifically its approaches toward policy governance.

Bridge construction is almost complete in many countries. Thus, the government and highway agencies change their focus from constructing to maintaining. Effectively maintaining bridges require predicting their lifespan using a system reliability viewpoint. Likewise, maintenance models based on the system reliability concept should be developed. Thus, this study developed maintenance models for preventive maintenance and essential maintenance using system reliability and lifetime distributions. The optimal maintenance strategy for an existing bridge was obtained using the developed maintenance models.

The degeneration of tool in material removal processing machinery can be characterized by wear, deflection, chattering and any failure in tool or in the material In be processed. In the previous studies, first three of them are analyzed as a preventive maintenance strategy in quality control area. The last of them, any failure, is analyzed as a preventive maintenance strategy in reliability area. In this research, we propose a simple integrated mathematical model which minimizes the cost of machinery failures and producing defects. We determine the optimal wear limit of tool by considering the percent defects. cost, the preventive maintenance cost, and the corrective maintenance cost.

As a system complexity increases and technology innovation progresses rapidly, leasing the equipment is considered as an important issue in many engineering areas. In practice, many engineering fields lease the equipment because it is an economical way to lease the equipment rather than to own the equipment. In addition, as the maintenance actions for the equipment are costly and need a specialist, the lessor is responsible for the maintenance actions in most leased contract. Hence, the lessor should establish the optimal maintenance strategy to minimize the maintenance cost. This paper proposes two periodic preventive maintenance policies for the leased equipment. The preventive maintenance action of policy 1 is performed with a periodic interval, in which their intervals are the same until the end of lease period. The other policy is to determine the periodic preventive maintenance interval minimizing total maintenance cost during the lease period. In addition, this paper presents two decision-making models to determine the preventive maintenance strategy for leased equipment based on the lessor's preference between the maintenance cost and the reliability at the end of lease period. The structural properties of the proposed decision-making model are investigated and algorithms to search the optimal maintenance policy that are satisfied by the lessor are provided. A numerical example is provided to illustrate the proposed model. The results show that a maintenance policy minimizing the maintenance cost is selected as a reasonable decision as the lease term becomes shorter. Moreover, the frequent preventive maintenance actions are performed when the minimal repair cost is higher than the preventive maintenance cost, resulting in higher maintenance cost.
