  • This paper investigates the stress-reducing preventive maintenance model through numerical experiments. The preventive maintenance model is used to analyze the relationship between related conditions and variables to gain insight into the efficient operation of the system when performing preventive maintenance in real-world situations. Various preventive maintenance models have been developed over the past decades and their complexity has increased in recent years. Increasing complexity is essential to reflect reality, but recent models can only be interpreted through numerical experiments. The stress-reducing preventive maintenance is a newly introduced preventive maintenance concept and can only be interpreted numerically due to its complexity, and has received little attention because the concept is unfamiliar. Therefore, for information purposes, this paper investigates the characteristics of the stress-reducing preventive maintenance and the relationship between parameters and variables through numerical experiments. In particular, this paper is focusing on the economic feasibility of stress-reducing preventive maintenance by observing changes in the optimal preventive maintenance period in response to changes in environmental stress and the improvement factor. As a result, when either the environmental stress or the improve effect of stress-reducing preventive maintenance is low, it is not necessary to carry out the stress-reducing preventive maintenance at excessive cost. In addition, it was found that the age reduction model is more economical than the failure rate reduction model.

  • From the start of the residency trainingship in 1963, the residency training programs have been contributed much on the establishment and development of preventive medicine in Korea. But these programs are now have several problems to update the changes in health service needs of the population that were caused by a rapid epidemiologic transition from the acute infectious diseases to chronic diseases in last a few decades. Strengthening in medical practice, not just in knowledge is urgently required. Must have more concentrate on preventive service for the individual, as in clinical preventive medicine. Training residents by the systematic and well scheduled programs, not just 'teacher' assistant' in the academic facilities. Trying the change in the system of Specilty of Preventive Medicine to the well established several subspecialty, so more specific competency can be gained through the training. These approach and reformation may not only contribute for the better future of the preventive medicine, but also improve in disease prevention and health promotion, which required by the society in Korea.
