With mobile computing, wireless sensor network and sensor technologies, ubiquitous computing services are being realized and could satisfy the feasibility of ubiquitous healthcare to everyone. This u-Healthcare service can improve life quality of human since medical service can be provided to anyone, anytime, and anywhere. To confirm the vision of u-Healthcare service, we've implemented a healthcare system for heart disease patient which is composed of two components. Front-end collects various signals such as temperature, blood pressure, SpO2, and electrocardiogram, etc. As a backend, medical information server accumulates sensing data and performs back-end processing. To simply transfer these sensing values to a medical team may be too trivial. So, we've designed a model based on context awareness for more improved medical service which is based on artificial neural network. Through rigid experiments, we could confirm that the proposed system can provide improved medical service.

Recently, as people's interest in health care has been rising, the health care service awareness and utilization has been increasing. However, the existing healthcare services have problems such as inconvenience of mobility, the low reliability of input for information and low accuracy of information provided as well. in this study, we developed the m-Health application by utilizing smart phone with improvement of these problems. This application provided the total of 5 services such as notification for risk of cardiovascular disease, personalized dietary recommendations targeted to 20s and 30s who do not properly manage their health care by bad habits. In addition, the benefits and problems of these services were found out through the analysis for the general importance and satisfaction of these services by Importance-Performance Analysis (IPA) technique. In result of IPA analysis, The six items such as 'input accuracy and reliability of information', 'content reliability', 'proper health service recommendations', etc. among 12 of the items needed to receive the effective services on m-Health were belonged to importance and satisfaction area with high level. And, in the 'information security', the importance is high but the satisfaction was low. In conclusion, the further study for strengthening security of information, service update provided with PHR to consistently keep the advantage of these services will be conducted.

유비쿼터스 환경중 상황에 따라 필요한 행위를 컴퓨터가 수행하여 사용자 각각의 특성에 따라 서비스를 할 수 있는 가장 좋은 것이 헬스케어 분야이다. 기존 헬스케어 시스템은 클라이언트/서버 환경으로 많은 환자들의 생체 신호 데이터가 실시간으로 서버로 전송될 때 서버의 일정 수용 한계를 넘어서게 되어 심한 경우 서버가 다운되는 현상이 발생할 수 있다. 이는 긴급한 환자의 처리에 대처하지 못하는 심각한 상황을 초래 할 수 있다. 또한 생체 신호를 보내는 모바일 디바이스의 자체적으로 지원되는 자원 부족으로 환자와 병원 중앙 서버와의 원활한 커뮤니케이션의 제공을 보장하지 못하는 단점도 있다. 이런 문제점을 해결하기 위하여 본 논문에서는 중간에서 환자와 병원사이의 중간 역할을 하는 써로게이트 시스템과 멀티 에이전트 시스템을 제안한다. 멀티에이전트 시스템은 중앙집중적 부하를 줄이고 유연성 있고 복잡한 처리가 가능하도록 한다. 이는 하나의 에이전트로 해결하지 못하는 복잡한 문제의 해결을 여러 에이전트의 협동을 통해 작업을 수행한다. 이를 위해서 본 논문에서는 JADE 를 기반으로 하는 에이전트 기술을 적용하였다. 모바일 디바이스에 인가되지 않은 접근을 막기 위한 수단으로서, 모든 메시지는 써로게이트를 통해 전달된다. 또한 써로게이트를 통해 로컬 및 원격의 에이전트를 쉽게 다룰 수 있다

개인 휴대단말기로부터 측정된 생체정보 데이터가 PHR에 데이터베이스화되기 위해서는 응용 계층 표준 프로토콜인 HL7 CDA 표준에 따라야 한다. 하지만 국제 표준 HL7 CDA는 병원 시스템 간 의료정보 전달을 위한 프로토콜이기 때문에 개인 건강 기기로부터 측정된 생체 정보가 IEEE 11073 PHD 표준에 준하여 전달하더라도 HL7 CDA 프로토콜과 연동될 수 없다. 즉, 모바일 단말기 기반의 u-헬스케어 모니터링 서비스를 위해서는 IEEE 11073 PHD와 HL7 CDA 간 메시지 변환 게이트웨이가 필요하다. 이에 본 논문에서는 개인 휴대단말기를 통해 원격지에 있는 의료진이 사용자의 생체데이터를 실시간 관리하기 위해 ISO/IEEE 11073과 HL7 CDA 간 메시지 변환 게이트웨이 및 HL7 기반 진단지원시스템을 설계하였다.
