In this paper, using the Android-based mobile platform designed and integrated U-healthcare systems for personal health care system is proposed. Integrated Biometric systems, electrocardiogram (ECG), oxygen saturation, blood pressure, respiration, body temperature, such as measuring vital signs throughout the module and signal processing biometric information through wireless communication module based on the Android mobile platform is transmitted to the gateway. Biometric data transmitted from a mobile health monitoring system, or transmitted to the server of U-healthcare was designed. By implementing vital signs monitoring system has been measured in vivo by monitoring data to determine current health status of caregivers had the advantage of being able to guarantee mobility respectively. This system is designed as personal health management and monitoring system for emergency patients will be helpful in the development looks U-healthcare system.

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.

Purpose: This study was conducted to explore the experience of smart-home healthcare among older adults who had participated in the smart-home technology development project. Methods: Data were collected by focus group interviews with 7 hypertension or diabetes participants(mean age 75 years). Qualitative contents analysis was used to analyze the verbal data. Results: The results were composed of 27 meanings units, 10 categories and 6 themes. The 6 themes are: 'improvement of health conditions through anytime anywhere self-monitoring', 'attractive experience to be counselling at home', 'frequent system and telecommunication problems', 'unfamiliar devices for elderly users', 'complementary strategies for activation', 'advancement of elderly-friendly devices and programs'. Conclusion: The smart-home healthcare system should be developed based on older adults' preferences. It is essential to make progress with professional resources and organizational supports in the future.

We developed a Smartphone application based on PHR(Personal Health Records) provided by a tertiary hospital to provide users personalized diet, exercise contents. It uses Relevance ratio algorithm of diet and excercise being correlated with diseases listed on PHR to provide personalized contents to management of individual diseases and record the amounts of food taken and exercise along with calories consumed through exercise. Besides, developed U-Health Service also considering users' conditions and conveniences, as a service to use contents and record suitable for the individuals who share the information on restaurants locations, their menus, and nutrition based on users' location information.

Purpose: The purpose of the study was to understand low-income elders' experiences of community-based u-Health services. Methods: Qualitative data were collected from 11 participants. All interviews were recorded and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. Results: Three themes and eight sub-themes emerged as a result of analysis. The three main themes were 'recovered confidence and health condition,' 'trial and error in change,' and 'hope.'The eight sub-themes were 'the burden and efforts to overcome it in using bio-signal device,' 'ambivalence due to changing lifestyle,' 'increase of care time, decrease of pressure', 'conflict under environmental constraints,' 'difficulty in prioritizing health management,' 'discouragement in handling new devices,' 'desire not to be a burden to their children-gradual fulfillment of learning needs,' and 'long for broadening coverage range of services.' Conclusion: The findings of this study demonstrate that low-income elders among the participants have different needs in using u-Health services. Therefore, health professionals need to give personalized education to deal with their conflicts and requirements, especially emotional and environmental support in order for them to successfully accept the u-Health services for self-care.

생활 속 사물들을 유 무선 네트워크를 이용하여 상호 연결하고 정보를 공유하는 환경을 사물인터넷이라고 한다. 즉, 인터넷을 기반으로 모든 사물을 연결하여 사람과 사물, 사물과 사물 간의 정보를 상호 소통하는 지능형 기술 및 서비스로서 기존의 유선 통신 기반 인터넷 및 모바일 인터넷보다 진화된 다음 단계의 인터넷을 의미한다고 볼 수 있다. 이러한 사물인터넷은 가전제품을 비롯한 전자기기뿐만 아니라 원격검침, 헬스케어, 스마트홈, 스마트카, 스마트팩토리 등의 다양한 분야에서 가정 및 산업용으로 응용되고 있다. 본 논문에서는 임베디드 디바이스를 사용하여 가정의 전자기기를 사용환경을 구성하고 이러한 장치들과 소통하고 제어할 수 있는 웹 기반의 플랫폼 환경에 대하여 제안한다.

This study empirically analyzed the factors affecting satisfaction and consistent use of 'home training' on personal media service YouTube based on Post-Acceptable Model. To this purpose, data were collected from adult men and women with personal media service using experience. As for data analysis, frequency analysis, correlation analysis, confirmatory factor analysis, reliability analysis and path analysis were performed by using SPSS 21.0 and AMOS 21.0. The results of the study were as followed. First, using motivation of YouTube home training had a positive effect on usefulness. Second, health literacy had a positive effect on usefulness. Third, it was found that the expectation confirmation of the home training on personal media service positively influenced usefulness. Forth, expectation confirmation of the home training on personal media service had a positive effect on satisfaction. Fifth, usefulness had a positive effect on satisfaction. Sixth, usefulness had no significant effect on consistent use intention. Seventh, satisfaction had a positive effect on consistent use intention. Behavioral analysis with collective demographic factors and diverse analysis considering the differentiation of the personal media service are suggested for further research.

The world today, has come to an age of diverse paradigms and technologies being developed, and technology of a new field is realized by merging technologies of different fields.One of such, u-Health system refers to a system which can monitor its users, regardless of time and place, using many body sensor datas based on USN (Ubiquitous Sensor Network). In the past, this kind of u-Health system was able to collect sensor datas through wires and could be monitored only by using PC (Personal Computer), but with development in technology, the system is now becoming possible to collect sensor datas wireless and monitor unhindered by time and place. This research aims to collect sensor datas of the user, and through Jena inference network, provide web service and smartphone application which enables checking of user's body datas in times of emergency, whenever, wherever.

The rapid aging is increasing as the shortage of medical facilities and the resulting of decline in the quality of public health. In order to ease the burden of rising medical expenses, advanced medical institutions are expanding their remote medical care to lower the cost of services. U-healthcare detects the changes in physical and chemical phenomena occurring in the human body and converts them into electrical signals that can be processed and feeds back to the results through analytical and visualization processes to select only the desired information from the measured signals. The service is provided through a process of providing an alarm to a user. However, traditional biometric methods of attaching sensors directly to the body can be annoying and rejected in daily life. Therefore, there is a need for a method of continuously measuring biometric information without causing inconvenience to daily life. In this paper, we propose an IR-UWB-based non-contact and non-responsive respiratory measurement system that can continuously monitor biological information without any inconveniences to daily life.
