세계 최고로 예상되는 급속한 인구구조의 고령화로 향후 우리나라는 보건, 의료, 복지 등에서 심각한 사회 문제에 직면할 것으로 예상되고, 고령화 사회로 인한 만성질환 증가는 의료비 증가로 이어져 국가 재정에 대한 부담으로 작용할 것이다. 정보통신기술을 이용하여 시간과 공간에 구애 받지 않고 언제 어디서나 건강과 생활을 관리하여 건강한 삶을 유지시키는 새로운 형태의 서비스인 유헬스(ubiquitous-Health)가 주목을 받고 있다. 일반인, 고령자, 만성질환자를 대상으로 하는 유헬스용 개인 건강 기기의 개발은 기존의 제품에서 네트워크와 연동이 되는 제품으로 보급되고 있으나, 데이터 상호 운용성이 고려되지 않은 제품이 주류를 이루고 있어 향후 진정한 유비쿼터스 개념의 건강관리를 위한 서비스를 실현하는데 문제가 될 것으로 예상되고 있다. 유헬스 기술이 표준화 되면, 생체정보 데이터의 취합 및 전송, 분석 및 피드백이 표준적인 방법으로 운용이 될 수 있으므로, 개인 건강 기기들과, 이들을 처리하는 유헬스 서비스간의 상호 운용성이 보장이 된다. 본 고에서는 최근 유헬스 분야에서 가장 활발한 표준화가 진행중인 IEEE 11073 PHD 표준화 동향에 대해서 살펴보고, 본 연구원에서 개발한 국제 표준기반 유헬스 플랫폼에 대한 소개를 한다.

Lately, in accordance with the improvement of living standards and income level, concern about the health is continuously increasing and the desire is also becoming diverse. This study focused on the user's acceptance of converged smart u-health system. For the study purpose, this paper analyzed the health and technology factors influencing the user's acceptance on u-health system. Thus this study was carried out by using covariance based SEM in order to test the model fitness and path coefficient. As the results, the health management experience among HPM factors and perceived usefulness among TAM had a positive effect on attitude and the perceived usefulness had a direct effect on behavioral intention.

The advancement in ubiquitous healthcare specifically in preventive healthcare can lead to longer life expectancy especially for the elderly patients. To aid in preventing premature loss of lives as well as lengthening life span, this research aims to implement the use of mobile and wireless sensor technology to improve the quality of life and lengthen life expectancy. The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. Therefore, we propose Context-aware Service of U-Healthcare Application based Knowledge using Ontology in secure health information exchange. This research also applies ontology in secure information exchange to support knowledge base, context modeling, and context reasoning by applying the general application areas for ontologies to the domain of context in ubiquitous computing environments. This paper also demonstrates how knowledge base, context technologies, and mobile web services can help enhance the quality of services in preventive ubiquitous healthcare to elderly patients.

The purpose of this study was to analyze the factors on behavioral intention in u-health system using Health Promotion Model(HPM) by Pender [11]. This study used PLS-SEM(Partial Least Squares-Structural Equation Modeling) method for verification of the proposed model and conducted the analysis with sample data of 216 respondents. As a result of the analysis, a path from individual experience to personal health and also, path from self-efficacy to behavioral intention had the highest influence in the research model. Also, it was confirmed that the only factor that affect health promotion behavior was 'self-efficacy' variable in u-health system. However, in the future time, additional research is needed in that this study has small sample data and needs more clear definition on u-health system.

The aim of this study was to search for the effects of health self-efficacy and technology self-efficacy on user's behavioural intention by the extended TAM focused on smartphone base ubiquitous health system. In this research, in view of small sample size, PLS - SEM methodology was applied to this study in order to the proposed research model. As a result of analysis, the statistical fitness of proposed research model was confirmed through GoF value and the path coefficient was calculated for the hypotheses test. Finally, the implications of analysis result showed that when the use of smartphone device could be easily accessed in the side of technology self-efficacy, the possibility of user's behavioural intention also might be higher.

The aging population and the advancement of science and technology are transforming the healthcare industry to focus on health management for the prevention of diseases. The U-health and remote healthcare services have not yet achieved the social agreement in the nation; however, these have been extensively used in the global scale. The innovation of user experience through cognitive computing are expected to increase the health effects of consumers, by converging with healthcare information services. This study suggests the conceptual model of healthcare information service converged with cognitive computing. Then, the acceptance factors for consumers have been investigated. For this purpose, reliability and validity analysis have been conducted using an online survey. The path analysis was performed to verify the hypotheses and moderating effect based upon the gender, by using structural equation modeling.

u-Health refers to "Always, ubiquitously" prevention against disease, diagnosis, medical treatment service that can receive treatment even if patient does not visit hospital as abbreviated word of ubiquitous and health. U-Health transmits in individual's living body sign and measuring of health information and health information system that is consisted of process of analysis and feedback transmiting and measure individual's living body signal and health information and health proprietary company or medical institution operates. If analyze pattern to information that health information system is transmited, health care officer or chief physician means that offer healthcare and medical treatment service to remote about target customer. Wish to present authoritativeness model for u-Health's inside and outside of the country same native place and u-Health's BMT in this research.

As a key technology of U-health, RFID can be applied to the hospitals in a variety of cases such as patient tracking, medical instrument management, and so on. However, adoption of RFID in healthcare does not reach expectations because of huge cost. Exact estimation of cost and effectiveness will boost adoption of RFID in healthcare. This study proposes a novel simulation technique to evaluate cost and effectiveness of RFID in hospital environment. To do this, this study proposes a technique for modeling patients' movements in a hospital. Based on the model, this study provides how to obtain tag event dataset by means of simulating identifications of RFID tags that are attached to patients.

This paper provides a review of the electrical sensing biosensors and examine research cases of biosensors based on clothing and textiels. A biosensor which can measure bio-signals is a device that senses the physical and chemical characteristics of biological materials by using biological sensing materials. Therefore, wellness wear that is closely integrated with the user's real life will play an important role in achieving U-Health. The biosensors' unique feature which can be differentiated from the existing sensors is it's using of selective reactions and binding of biological substances. The electrical sensing biosensors are very small in size due to the processing of electrical signals, which can be used to create ubiquitous. Therefore, it is necessary to study electrical sensing biosensors that are easy to miniaturize to develop wellness wear. This paper describes the electrical sensing biosensor (an electrochemical method nanowire/carbon nanotube FET method) in detail. Finally, the future direction of biosensors to be applied to wellness wear is suggested.
