Recent expansion of the ubiquitous environment and improvement of the USN give lots of U-healthcare systems. In this paper, we design and implement a wireless ECG measurement system that can send ECG signals among the sensors and collector. It can also give almost the same precision as a hospital ECG system with mobility. The most important fact of the mobile ECG system is the signal data connectivity among the sensors and device such as signal cables or wires. we can eliminate the signal cable through the Zigbee sender and collector via implementing Zigbee-SD communication system that can receive the ECG signal data. We also implement ECG app software on the smart phone that can analyze and show the data results directly. It can give lots of mobility and usability under ubiquitous environment and would be a very efficient wireless ECG system for U-healthcare service.

This study aims to investigate the impact of a mobile-based human coaching healthcare service provided for diabetic patients by nurses on their self-management ability. This study collected data from 311 persons who were diagnosed with diabetes from all over the country, and the collected data were analyzed through SPSS Win 23. The results of the study are summarized as follows: First, it was found that the utilization of a glucose meter by the provision of the mobile-based human coaching healthcare service was men group, and there was a statistically significant difference (${\chi}^2=6.059$, p= .048*). Second, there was a positive correlation in the utilization between the glucose meter and an activity tracker band by the provision of the mobile-based human coaching healthcare service, which was statistically significant (r=.660, p< .001). Third, as a result of checking the changes of the utilization of the glucose meter by the provision of the mobile-based human coaching healthcare service, it was maintained between 79% and 41% from Week 1 through 49. In conclusion, this study partially confirmed that the mobile-based human coaching health service was easily accessible and cost-effective in enhancing the participants'self-healthcare ability.

The purpose of this study was to identify the effect of the Smart Care ubiquitous healthcare service on hypertension management. Fifty one patients with inadequately controlled blood pressure (Systolic Blood Pressure ${\geq}$ 140 mmHg despite prescribed antihypertensive medication) from 4 local clinics participated in this study. Remote biometric monitoring and healthcare consultation via videophone was provided to the participants during 24 week - Smart Care service. The average number of blood pressure monitoring and the average day of remote consult using Smart Care Service system was 121 and 14.8 per participant. As a result of analyzing change in blood pressure during 24 weeks, there was a significant difference in blood pressure between baseline and 24 weeks. Systolic blood pressures of 86.3% participants were dropped within a normal range at 24 week. Smart Care u-health service could be effective in reducing blood pressure.

Nowadays hospitals have been improving their job performances through informatization and also establishing an advanced, integrated medical information system through their manager's decision making support system in order to play roles as a hub hospital providing high quality medical services integrated with ICT technology. This study connects the OCS system and HIS system to the integrated medical information system to design an optimized, customized mobile health care and medical treatment environment and also investigates the systematic medical system that can perform patients' cure and medical treatment promptly and accurately in order to maximize convenience of treatment by inquiring into patients' information and information of medical treatment promptly.

Wireless access network section needs strong security which supports high data rate and mobility not to invade patient's privacy by exposing patient's sensitive biometric from automatic implantable device that is adapted to u-healthcare service. This paper builds test bed and performs assessment and measurement of security ability of WiMAX network to transmit and receive mobile patient's biometric by building WiMAX network in wireless access network not to expose paitne's biometirc at wireless access network section to the third person. Specially, this paper compares and assesses data security, MAC control message security, handover conection delay, and frame loss and bandwidth of ECDH at the layer of WiMAX security compliance, WiMAX MAC IPSec, and MAC.

최근에 우리 사회는 불규칙적인 식습관, 부족한 운동, 과도한 스트레스 등으로 만성질환 및 성인병 환자가 늘어나는 심각성이 날로 커지고 있다. 성인병의 심각성은 40대 이상에서 크게 대두 되었던 과거와 달리, 최근에는 20대를 넘어서서 10대 청소년에게까지 성인병을 앓고 있는 환자들이 날로 많아지고 있다. 세계적으로 IT가 크게 발달함에 따라 병원과 환자가 서로 만나지 않아도 24시간 소통이 되는 u-Healthcare 시스템이 크게 대두되고 있다. 이에 따라서 환자 개개인과 주치의가 시 공간에 제약받지 않고 상호 긴밀하게 진료, 검사 및 피드백이 가능하게 된다. 본 연구진은 u-Healthcare 시스템에 부합하고 스마트 폰을 이용하여 만성질환자를 관리할 수 있는 u-DailyCare 시스템을 설계하고 구현하였다. 스마트 폰 사용자로부터 얻어진 생체 정보 데이터 및 행위 데이터들을 수집하여 서버에 보내면, 주치의는 종합된 전체적인 데이터를 실시간으로 확인하여 환자의 상태를 검토 및 진단하여 피드백을 준다. 본 논문에서는 u-DailyCare 시스템의 설계 및 구현과정을 설명할 것이다.

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.

In this paper, we developed u-Care service system using technologies of USN and LBS to help construct social welfare infrastructure and social safety net for lone seniors and handicapped people. This service not only monitors the in-house and outdoor activities of those disabled people but also sends the messages, whenever abnormal behaviors are detected, to the people related to them as well as the social welfare organizations and public safety institutions such as police and emergency services and etc in order to alert them.
