본 연구의 목적은 모바일 헬스케어 앱의 사용자 경험 요인을 분석하여 제안하는 데 있다. 의료 관련 앱은 주로 의료 서비스 제공자 중심의 기능으로 디자인되어 개인의 서비스 접근성이 낮으며, 데이터 활용에 대한 고려가 부족하다. 개인이 주도적으로 건강 데이터를 활용하기 위해서는 개인 - 건강 데이터 커뮤니케이션을 고려한 앱 개발이 필수적이며, 이와 관련된 사용자 경험을 평가하는 도구가 필요하다. 먼저 문헌 조사를 통해 사용 편의성, 사용 만족도, 정보 구조, 유용성, 정보 품질, 심미성 6가지 사용자 경험 요인을 수집하였다. 이후, '나의건강기록' 앱을 대상으로 사용자 심층인터뷰를 진행하여 모바일 헬스케어 앱 사용자 경험에 영향을 주는 요인을 분석하였다. 심층인터뷰 결과, 사용자 경험 요인에 정보의 이해용이성 요인이 새롭게 도출되었다. 정보의 이해용이성은 건강 정보를 알기 쉽게 제공하여, 사용자들이 어려움 없이 정보를 이해할 수 있는 능력을 의미하고 건강정보이해능력과 관련이 높다. 각 도출된 요인은 정보 주체(사용자)의 편의성, 활용성, 유지율을 높일 수 있는 모바일 헬스케어 앱을 디자인하는 데 유용할 것으로 기대된다.

Hypertension is one of the major causes of death in the world as it is related with cardiovascular or cerebrovascular disease, so it is needed to provide continuos management for blood pressure. This study selected Health Level 7 Fast Health Interoperability Resources (HL7 FHIR) as a bio-signal data exchange service model that can provide constant blood pressure management in the rapidly growing mobile health care environment. The HL7 FHIR framework developed communicates with the IEEE 11073-10407 Personal Health Device (PHD) protocol through the bluetooth Health Device Profile (HDP) between the manager (smart phone) and the agent (hemomanometer) and acquires information about blood pressure. According to the test results, it performed its tasks successfully including hypertension patients' blood pressure monitoring, management on measured records, generation of document, or transmission of measured information. Because in the actual, clinical environment, it is possible to transmit measured information through the TCP/IP protocol, it will be needed to conduct constant research on it and vitalize it in the field of mobile health care afterwards.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.

In recent years the combination of IT and BT for U-Healthcare Medical Services has attracted popular attention as an alternative for solving health problems due to aging issue. Active oxygen as free radicals causes unstable state of the body resulting to other disease on which approximate 90% of the diseases are associated with active oxygen. The severity is even higher along with increasing age. Therefore, there is a need for systematic management of active oxygen saturation for the elderly and chronic patients. In this paper, the data about active oxygen measurements from the body measurement is sent to the data storage of medical facilities by the service provider. Medical information is measured by devices provided complying with the standard, support and information using Bluetooth communication. Users can check their health status themselves using the proposed system through 3G/4G mobile devices like smart phone to medical institutions in which the smart phone act as a gateway for medical data transferred from patient to medical institutions and vice versa. Users can get and experience a diagnosis and effective U-Environmental Health Services from Medical institutions anywhere using the proposed built system.

Mobile healthcare is a fusion of information technology and biotechnology and is a new type of health management service to keep people's health at anytime and anywhere without regard to time and space. The WBAN(Wireless Body Area Network) technology that collects bio signals and the data analysis and monitoring technology using mobile devices are essential for serving mobile healthcare. WBAN consisting of users with mobile devices meet another WBAN during movement, WBANs transmit data to the other media. Because of WBAN conflict, several nodes transmit data in same time slot so a collision will occur, resulting in the data transmission being failed and need more energy for re-transmission. In this thesis, we proposed a MAC protocol for WBAN with mobility to solve these problems. First, we proposed a superframe structure for WBAN. The proposed superframe consists of a TDMA(Time Division Muliple Access) based contention access phase with which a node can transmit data in its own time slot and a contention phase using CSMA/CA algorithm. Second, we proposed a network merging algorithm for conflicting WBAN based on the proposed MAC protocol. When a WBAN with mobility conflicts with other WBAN, data frame collision is reduced through network reestablishment. Simulations are performed using a Castalia based on the OMNeT++ network simulation framework to estimate the performance of the proposed superframe and algorithms. We estimated the performance of WBAN based on the proposed MAC protocol by comparing the performance of the WBAN based on IEEE 802.15.6. Performance evaluation results show that the packet transmission success rate and energy efficiency are improved by reducing the probability of collision using the proposed MAC protocol.

The research focused on plastic surgery clinics in Seoul, which recently responded to foreign patients who wanted to get plastic surgery, to recognize the need for the use of mobile healthcare applications to promote medical tourism and to see the expected effects in the future. For the analysis of data, SPSS 21.0 was used. Based on personal characteristics and medical institution characteristics, the future expected effects of using mobile healthcare applications were analyzed to find ways to help vitalize medical tourism. The result showed that the more mobile applications they wants to use in the future and the higher the number of foreign patients of the medical institutions, the more positive the expectation on the use of mobile healthcare application in the future. Also, the higher evaluation on the need for mobile healthcare application, the more helpful in vitalizing the medical tourism in the future, and the higher the positive awareness. I hope that this research will provide an IT foundation for the and expansion of mobile service app on demand analysis and service utilization of medical workers in order to promote medical tourism.

모바일 환경의 발달과 스마트 폰 사용자가 증가하면서 의료서비스 환경에도 큰 변화를 가져왔다. 시간과 장소에 구애 받지 않고 실시간으로 의사와 환자의 소통이 가능해졌다. 하지만 무선환경에서 환자의 의료정보가 허가되지 않은 사용자에 의해 유출 되고 개인의 사생활의 침해가 우려되고 있다. 또한 헬스케어의 데이터는 환자의 건강과 밀접한 관계가 있어 데이터 위/변조가 일어날 경우에는 환자의 생명에도 영향을 미칠 수 있다. 따라서 본 논문에서는 스마트 헬스케어(Smart Healthcare)의 스마트보안 기술 핵심요소인 기밀성, 무결성, 사용자인증, 모바일 보안에 적합한 시스템을 설계하였다.

This paper implemented the u-Healthcare Context Information System (HCIS) supporting ubiquitous healthcare by using location, health and titrating environment information collected from sensors/devices equipped in home for healthcare home service. The HCIS is based on the Distributed Object Group Framework (DOGF), a management model which can customize distributed resources, and manages various context information, applications and devices as a group in healthcare home environment, as one more logical units. Also, this system provides continuous healthcare multimedia service considering a resident's location using Mobile Proxy, and the healthcare context information through Context Provider to a resident in home. For verifying execution of our system, we implemented the seamless multimedia service based on resident's location and the prescription/advice and schedule notification/alarm service as healthcare applications in home. And we showed the executing results of healthcare home service by using service device existed in the residential space on which the resident is located according to the healthcare scenario.
