By using personal health devices, a type of bio-censor at home and building, for telemedicine, this paper proposes a new method to protect more robust patient's privacy than before scheme [1] by ensuring the integrity and the secure transmission further when it communicates with gateway which collecting bio-information from them. As the suggested method is designed to conform with ISO/IEEE 11073-20601 [2], which is international standard, it considered interoperability with various health devices.

최근 급성 질환으로 인한 사망률은 꾸준히 증가하고 있다. 이러한 급성 질환은 초기 증상 발생 시 올바른 인지와 신속한 대처가 요구된다. 그러나 유지 관리비용 면에서 모든 개인의 응급상황을 관리할 수 있는 의료시스템은 구축하기 어렵다. 본 논문에서는 언급한 문제점을 해결하기 위해 웨어러블 디바이스와 개인건강기록 시스템을 제안한다. 웨어러블 디바이스에서 측정한 심박 체온의 생체신호로 응급 상황을 판별해 지정된 보호자에게 알린다. 또한, 응급버튼을 통해 곧바로 응급상황을 알린다. 개인이나 가족과 관련된 건강정보를 관리할 수 있는 개인건강기록(Personal Health Record)을 제공한다. 본 시스템을 통해 사용자의 응급상황에 신속하게 대처하여 생명을 보호할 수 있을 것으로 기대한다.

통신기술의 발전이 가져온 스마트 시대로의 진입은 다양한 스마트 디바이스와 콘텐츠 및 문화를 보급, 창출해내며 우리 사회 전반적인 라이프 스타일의 변화를 선도하고 있다. 특히 국민소득의 증대로 건강에 관한 소비자 욕구가 증대하면서 더 나은 삶의 질을 추구하는 웰니스가 급부상함에 따라, 치료 중심이 아닌 예방과 케어, 힐링을 위한 다양한 서비스를 위한 디바이스와 플랫폼, 분석기술의 개발 및 적용이 요구되고 있다. 또한 단순히 서비스를 제공받던 수동적인 과거 소비자 형태가 스마트 디바이스를 적극적으로 활용해내는 능동적 소비자의 모습으로 변화함에 따라 이러한 움직임은 앞으로 단순히 서비스 제공의 측면이 아닌, 웰니스 증진을 위해 특화된 스마트 디바이스와 컴퓨터, 소비자와의 상호작용에 기반한 기술로 발전되어갈 전망이다. 본 논문에서는 건강은 물론 개인의 라이프 스타일을 포함한 라이프로그 기반의 다차원적인 정보 수집과 체계적 분석, 그를 통한 모니터링과 맞춤형 서비스를 실현하는 개인화웰니스기록을 활용한 개인맞춤형웰니스 관리 시스템을 설계하고자 한다.

As smart phone market has been rapidly saturated, wearable devices have been emerging as a new growth power in the post smart phone era. This study aims to comprehend the influential factors of purchasing intention of product features(perceived usefulness, perceived ease of use) and individual characteristics(innovation, fashion leadership, self-efficacy, concern for health) of wrist wearable device. The result shows that fashion leadership and health concern among consumers' individuality, and perceived usefulness and perceived usability among product features are proved to be significant factors. This means that both usefulness and usability have significant impacts on purchase intention of wearable device and product development should be made to enhance user experience.

The emergence of diverse medical Internet of Things (IoT) devices has facilitated the collection and analysis of medical contexts to assess health conditions. However, the complexity of IoT-based systems for health assessment is quiet high and it requires high development cost, since the designs of the systems highly depend on the heath aspects to be evaluated. In this paper, we propose a design of the platform that provides generic functionalities to various health evaluation applications. We first define a metric for computing a health index, which is a generic health assessment model. And, based on the proposed generic health index, we propose a design of the platform to evaluate diverse aspects of the health including its hardware architecture, software architecture and database design. We describe the result of developing Rainbow Toilet System based on the proposed platform, and assess the practical applicability.

Recent advances in wearable devices and quantified-self movement increase the number of personal informatics application that may cause an concern to health industry and user. In this light, the goal of this study is to identify more effective ways of design and evaluation of personal informatics application for self-tracking and delivering health information to users. For this goal, this study conducted areal-world study that processes such that user can assess, be aware of, and self-reflect on their data and behavior activity. In doing so, this study aims to determine the psychological effects of forms of health feedback (comparative vs. non-comparative) and presentation modes (text vs. image) on users' tendencies toward health conservation. Results from a between-subjects experiment revealed that health information in a comparative and textual format was more effective in encouraging health conservation in participants than identical information presented in a non-comparative and image format. In addition, participants' level of health consciousness emerged as a significant predictor. Through this analysis of quantitative data and inferences, this study make a number of contributions to the user affordance research and its methodology of health informatics study and designing personal informatics application that support user's behavior change in various contexts.

This study aims to examine the preferred device types, the difference of device properties by service types, and acceptance intention for applications and willingness to pay for healthcare services. To attain this goal, this research conducted a survey targeted to the subjects of those concerned in hospitals and medical institutions, the aged and patients with chronic disease, and consumers having interest in health maintenance. According to the result of the analysis, acceptance intention for mobile devices for healthcare services was high in general. And patients with chronic disease and those concerned in hospitals showed high acceptance intention. Smart phones were preferred the most in the support of healthcare services. And there was the difference of device properties by service types, and in health maintenance, easiness and playfulness were somewhat high. Acceptance intention for mobile applications was rather high in personal use, and regarding the properties, personal information protection was valued highly.

개인건강에 대한 관심이 날로 증대함에 따라 개인 건강 상태를 파악하기 위한 사용자 생활패턴인지 연구에 대한 관심이 높아지고 있다. 행위 인지 연구는 오랜 시간 진행되어 왔지만 고수준행위인지의 정확도가 여전히 미미하며 고수준행위의 세부 행위는 인지하지 않았다. 본 논문에서는 스마트폰과 웨어러블센서를 이용하여 실생활에서 보다 정확한 고수준행위데이터를 도출함으로써 더욱 넓은 분야에서 활용 가능한 기술 연구에 목적이 있다.

Recently, research about ESS(Emergency Support System) has been actively carried out to provide a variety of medical services using smart devices and wearable devices. Smart healthcare provides a personalized health care service using various types of bio-signal measuring sensors and smart devices. For the smart healthcare using a smart device, it is need to research about personal health monitoring using a smart wearable devices, and also need to research on service methods for first aid measures after an emergency. In this paper, we proposed about group management based emergency support system, that is monitoring about personal bio signal using smart devices and wearable devices to protect patient's life. The system notices to the medical volunteers based on the position information when an emergency situation. In addition, we have designed and implemented an emergency support system providing the information of the patient on the display when transmitting a picture of a patient using a smart device to the server.

모바일 헬스케어는 다양한 스마트 디바이스를 활용한 개인건강관리 기술을 말한다. 특히 스마트폰 보급과 근거리 무선 통신 기술의 발전으로 모바일 헬스케어와 관련한 여러 디바이스와 서비스들이 개발되고 있다. 그러나 이러한 디바이스와 서비스들이 대부분 자체적인 규격에 의해 굿현 되고 있으며 이로인해 기기 간 호환이 안 되고 서비스가 종속되는 등의 문제가 있다. 특히 규제가 엄격한 의료 서비스와 거리를 둔 일상적 생활에서의 건강관리 기기나 서비스들은 그 문제가 더욱 심각하다. 본 논문에서는 이러한 모바일 헬스케어 환경에서의 문제점 해결을 위한 표준 요소와 그 현황에 대해 살펴보고 관련 표준의 모바일 헬스케어 적용 모델을 제안 한다.
