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.

Purpose: We analyzed the need for home care services and awareness of U-healthcare in nurses of the Catholic Parish Home Care Center to link the ubiquitous health care system and the home care. Methods: We recruited 46 nurses from a home care center in the catholic parish of the C medical center from April 4th to June 8th, 2007. Results: The highest needs were 'assessment and diagnosis of the problem', 'management of hypertension & diabetes patients', 'counseling of the patient', and 'counseling of major caregiver and family problems'. Therapeutic nursing showed the highest needs in bedsore care. Nurses want hospital medical records available through the ubiquitous health care system. Conclusion: Home care services are supported from the agency, with high needs in assessing and diagnosing the problem, counseling, and managing of hypertension & diabetes patients. Education and public relations efforts on the U-healthcare system should improve system awareness.

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.

This paper is to estimate the market potentiality of ubiquitous health(u-health) from a viewpoint of communication companies. For this estimation, we used the CVM and adopted the ratio of ovum(2000) in overall market of u-health. That is, firstly, we assumed the u-business model was based on mobile business approach. Through this estimation, we conclude that communication companies at the initial stage of the u-health market can continuously promote the market share ratio via strategic alliance with the players participating.

In the era of ubiquitous computing, human-friendly man-machine interface is getting more attention due to its possibility to offer convenient services. For this, in this paper, we introduce a 'Half-Mirror Interface System (HMIS)' as a novel type of human-friendly man-machine interfaces. Basically, HMIS consists of half-mirror, USB-Webcam, microphone, 2ch-speaker, and high-speed processing unit. In our HMIS, two principal operation modes are selected by the existence of the user in front of it. The first one, 'mirror-mode', is activated when the user's face is detected via USB-Webcam. In this mode, HMIS provides three basic functions such as 1) make-up assistance by magnifying an interested facial component and TTS (Text-To-Speech) guide for appropriate make-up, 2) Daily weather information provider via WWW service, 3) Health monitoring/diagnosis service using Chinese medicine knowledge. The second one, 'display-mode' is designed to show decorative pictures, family photos, art paintings and so on. This mode is activated when the user's face is not detected for a time being. In display-mode, we also added a 'healing-window' function and 'healing-music player' function for user's psychological comfort and/or relaxation. All these functions are accessible by commercially available voice synthesis/recognition package.

With the advancement of ubiquitous computing technology, u-Healthcare (i.e. ubiquitous health care), is regarded as a key application for information society, which provides health management service at anytime in anywhere. To implement U-Healthcare system, it is essential to monitor stable biological information in daily life. In this paper, we proposed a small size, light weight, patch type real time temperature monitoring system based on wireless sensor network (WSN) technology to monitor patients' body temperature without any inconvenience of activity.

Various kinds of studies for building up U-Korea are now underway. Especially, RFID comes into the spotlight as a core technology of Ubiquitous. Though, the development of higher levels of application is far behind the hardware-based technology in RFID application system. For that reason, In this paper suggests technology using RFID on Ubiquitous and embodies the effective health care application which is one of the application services of user-centered environment It realizes the system which enables us to manage and send data about changing prescriptions and locations of patients effectively under the basis of RFID tag and mobile devices. It also provides the high quality of practical effectiveness of entire system throughout the realization of applications of application server and mobile device. on the basis of framework for providing the various kinds of services and physical elements.

Various studies on individual health-care application services have been lively going on due to recent development of information and communication technology and improvement of life quality. Moreover, U-health care area is emerging as a new growth industry as the demand of U-health care service for a quality life grows with the development of medical technology and ubiquitous environment. U-health care system for crew members on ships, who need to spend much time on sea far from their families, is especially needed because they find their job much more stressful not only physically but also mentally than any other people in different jobs do and have less chance to get proper medical services in time. In this paper, we suggested how to get more accurate and objective U-health wellbeing index by complementing SF-36, the general heath care index model in order to managing health of crew. Also we designed the U-health wellbeing index service system which can provide appropriate sports programs or diet contents according to health index.

The use of Radio Frequency Identification technology (RFID) in medical context enables not only drug identification, but also a rapid and precise identification of patients, physicians, nurses or any other healthcare giver. The combination of RFID tag identification with structured and secured Internet of Things (IoT) solutions enables ubiquitous and easy access to medical related records, while providing control and security to all interactions. This paper defines a basic security architecture, easily deployable on mobile platforms, which would allow to establish and manage a medication prescription service in mobility context making use of electronic Personal Health Records. This security architecture is aimed to be used with a mobile e-health application (m-health) through a simple and intuitive interface, supported by RFID technology. This architecture, able to support secured and authenticated interactions, will enable an easy deployment of m-health applications. The special case of drug administration and ubiquitous medication control system, along with the corresponding Internet of Things context, is presented.
