U-healthcare system has an aim to provide reliable and fast medical services for patient regardless of time and space by transmitting to doctors a large quantity of vital signs collected from sensor networks. Existing u-healthcare systems can merely monitoring patients' health status. In this paper, we describe the implementation and validation of a prototype of a u-health monitoring system based on a wireless sensor network. This system is easy to derive physiologically meaningful results by analyzing rapidly vital signs. The monitoring system sends only the abnormal data of examinee to the service provider. This technique can reduces the wireless data packet overload between a monitoring part and service provider. The real-time bio-signal monitoring system makes possible to implement u-health services and improving efficiency of medical services.

For digital TV, the recommendation of u-health personalized service of semantic environment should be done after evaluating individual physical condition, illness and health condition. The existing recommendation method of u-health personalized service of semantic environment had low user satisfaction because its recommendation was dependent on ontology for analyzing significance. We propose the personalized service recommendation method based on Naive Bayesian Classifier for u-health service of semantic environment in digital TV. In accordance with the proposed method, the condition data is inferred by using ontology, and the transaction is saved. By applying naive bayesian classifier that uses preference information, the service is provided after inferring based on user preference information and transaction formed from ontology. The service inferred based on naive bayesian classifier shows higher precision and recall ratio of the contents recommendation rather than the existing method.

Because Korea has the excellent informational technology, it was expected to be able to improve the accessibility to healthcare and compete with other nations in excellence through u-Healthcare. But we can't complete the excellent u-Healthcare because of the law to be able to use only the tele-counselling between doctor to doctor or doctor to nurse. First of all, we must complete the law to be able to use the improved u-Health containing of telemedicine between doctor to patient. Though other factors, the procurement of safe IT, the credibility to healthcare service provider containing of nutritionist and occupational therapist etc. are prepared for erecting u-Healthcare, we can get the final and decisive u-Health policy only by means of Law for supporting u-Healthcare's Activation. The important sections of Law for supporting u-Healthcare's Activation are as follows. Sec. 4 The Minister for Health, Welfare and Family Affairs and the dean of associated administrative division have to erect the combined plan for u-Healthcare's Activation. Sec. 11 Government and local autonomous entity can support the facility and equipment to be necessitated for using u-Healthcare to improve the medical accessibility of person in the region with poor medicine. Sec. 13 Doctor can support other doctor's medical action through IT and if there are not medical risk, doctor can give medical act directly to the special patients. Sec. 21 If pharmaceuticals is necessitated in u-Healthcare, remote doctor has to send the patient the electronic prescription and the pharmaceutist to receive the electronic prescription has to delivery the pharmaceuticals in accordance with patient's demand.

Korea is experiencing a rapid increase in the number of elderly living alone accompanying the aging society problem, a nd is making efforts to solve the problem through the policy of 'living alone u-care service'. The purpose of this study is to propose a better u-Care service improvement method by applying new technology to improve the user experience of ucare service for the health and safety of the elderly living alone. First, the improvement of u-Care service for elderly livin g alone by applying IoT technology. It provides remote monitoring service using health information data measured through wearable device, and transmits personal health status to medical institution by using personal device such as smart phone, so that remote medical consultation or telemedicine can be connected in the future. Second, improvement of u-Care service through consideration of emotional stability of elderly living alone as well as simple safety and health care through applica tion of emotional service robot technology.It is expected that it will be able to help independent living of one person's elde rly person in the future by providing caring function service to existing u-care service providing service.

This paper shows a u-Health management system in user's Life environment, which is different from previous ones by enterprises. It's designed for users(citizens) and service provider(especially providing medical service). This paper is discussing on the proof on the service model being operated near the Tancheon stream in the city of Sung-nam. To maximize users' satisfaction, this service has been designed on four disciplines(so easy, so simple, well-customized, funny feedback) in the viewpoint for users. Its algorithm has 4 levels which are measurement, prescription, monitoring and feedback. In the system. there are HCBs(health check boothes) checking out status and assessment of users, customized health prescription customized a health management service prescription engine, exercise programs customized on exercise equipments near the stream and monitoring system.

The purpose of this study is to analyze the demand for telemedicine and telehealthmanagement services, which are key elements of home based u-health. The conjoint analysis, which is a conventional method for demand analysis for newly introduced products, is employed, utilizing the survey data on 500 seoul citizens. Further, multivariate probit model is used to estimate the demand. The result shows that the demand for telemedicine services is greater than that of telehealthmanagement services. Further, home-based u-health services will play a role as a complementary for face-to-face medical treatments, rather than a substitute. Meanwhile, the demand for home-based u-health services is found to be very sensitive to price.

기존의 u-HealthCare 서비스는 환자에 대해서 일정한 공간에서의 센서의 on/off 타입에 대한 모니터링/환자관리의 서비스를 제공하였다. 이러한 환경하에서의 주된 서비스는 현재 환자의 상태에 대한 수동적인 형태이다. 이러한 문제점들을 해결하기 위해 센서 데이터에 대한 연속센서 데이터마이닝 기법을 이용한다. USN의 응용서비스인 u-HealthCare 서비스는 센서데이터로부터 생체정보 및 위치정보를 이용하여 환자/보호자/관련 의료진에게 필요한 정보를 제공한다. 이것은 환자에 대한 관리/모니터링뿐만 아니라 환자의 상태에 따른 센싱(sensing)된 데이터를 이용한 패턴(pattern), 예측-(prediction), 이상치(outlier)를 분석함으로써 보다 나은 서비스를 제공할 수 있다. 본 논문에서는 센서 데이터에 대해 새로운 연속 센서데이터 마이닝 기법을 적용하여 질의를 통해 지식을 추출하고 보다 지능화된 서비스를 제공할 수 있는 응용서비스 기법을 제안한다.

Ubiquitous healthcare is a recent technology and a new methodology of medical diagnosis and medical care. However, in order for u-Healthcare service to become a general technology, there are some technological barriers(mobility, minimization, battery consumption etc) to overcome. In this paper, we developed a spectrum analysis system for smart phones. The results showed that compared to other solutions, our's were not only small in size but also almost the same in performance(reproducibility comparison experiments, Spectrum, Calibration Curve and Prediction). Therefore, the proposed solution is expected to be widely used in u-Health area.

Recently, the RFID technology is combined with a u-healthcare services is an emerging trend in the field of medical services. u-healthcare service, as covering the field of personal health information beyond the level of simple health screening and treatment of life are closely related. Considering security, invasion of privacy, as well as life may be threatened even if your personal health information to be exposed or exploited illegally u-Healthcare services certification is essential. In 2012, Jeong proposed J-L patient authentication protocol that Initialization process, and patients using RFID technology separates the certification process. Jeong, such as the claim that the proposed protocol for reuse attacks, spoofing attacks, prevent information disclosure and traceability fire safety, but raises issues of security and operations efficiency. Therefore, in this paper, Jeong, such as the security of the proposed protocol and to prove the computational efficiency issues, and to enhance the safety and efficiency of RFID technology based on practical u-Healthcare services authentication protocol is proposed.
