Systems Health Care the aspect of home and medical care

The importance of measuring vital signs and life style activities in ordinary life besides in medical field has been realized more and more. This is because the affect of life style disease in super aging society has been strongly associated with long term nursing care. Additionally, sensing and information technology has been developed for realizing ease of use, cost reduction, and low intrusion. In this article, systems approach to health care is developed by centering home and medical care. The essence of the notion is using sensory data of vital signs and life style activities in both medical field and home by bridging between them to make medical treatment and home self-care efficient and effective. Systems Health Care mainly composes of Health Management and Knowledge Harvesting technologies. First one is designed for continuous health care and improvement by applying index, criterion, and causality. The second is for causal knowledge extraction process from sensory database, which is used in Health Management. The notion and the technologies are studied and discussed in the article. Application studies follow them by centering health care supporting system and employing both vital signal and life style activities monitoring. Blood pressure analysis program used in medical field as vital signal monitoring is employed. Regarding life style activities, active mass monitoring, non-contact sleep monitoring, and weight-loss programs are introduced.
