IPv6 and Ubiquitous Healthcare Environment (UHE) has become a main stream of the next generation technologies. IPv6 is designed in many ways with enhanced features such as a routing, mobility, scalability, QOS and security as a replacement of IPv4. Also, UHE is developed to provide patients with convenience and efficient healthcare services using the remote home healthcare system. However, IPv4 currently used as an Internet protocol does not have enough capability to fully support UHE. It may result in a restricted implementation of UHE. As a result, research on IPv6 implementations in UHE is increasingly becoming an issue within the healthcare industry. IPv6 has enhanced features to implement the remote healthcare system such as Neighbour Discovery process and address auto-configuration. In this paper, a basic of IPv6 and UHE will be firstly introduced and secondly, benefits brought by IPv6 in UHE will be discussed. In addition, security issues in IPv6 will be analysed to conclude this paper.

u-Healthcare 활성화의 필요성이 꾸준히 제시되어 왔으나, 아직까지 이해자들의 공감대를 이끌어 낼 수 있는 개념정립 및 분류체계가 미비한 실정이다. 새로운 서비스 영역인 u-Healthcare 분야 산업 발전을 위해서는 정책적 전략과 제도적 정비 등의 기반조성이 필요하며, 이에 앞서 명확한 개념 정의와 영역 범주화의 필요성이 제기되고 있다. 본 연구에서는 ubiquitous computing 속성에 대한 이해를 통해 u-Health 환경과 u-Healthcare를 정의하며, 보건의료적 접근에 의한 분류를 통해 보건의료서비스에의 적용가능 분야를 제시하고자 한다.

When unapproved users access to healthcare system and use medical information for other malicious purposes, it could severely threaten important information related to patients' life, because in ubiquitous environment healthcare service makes patient's various examination results, medical records or most information of a patient into data. Therefore, to solve these problems, we design RBAC(Role Based Access Control) for U-healthcare that can access control with location, time and context-awareness information like status information of user and protect patient's privacy. With implementation of the proposed model, we verify effectiveness of the access control model for healthcare in ubiquitous environment.

요즘 현대인들의 최우선 관심사라고도 할 수 있는 '웰빙(Well-Being)'과 다가올 '고령사회'를 대비하여 유무선 네트워킹 기술을 활용하여 "언제 어디서나" 이용 가능한 건강관리 및 의료서비스가 필요하다. u-Healthcare 시스템을 이용하여 개인의 건강상태를 실시간으로 모니터링하고 치료나 관리가 필요한 적절한 시점에 자동으로 조치를 취하기 때문에 개인은 최상의 건강상태를 유지할 수 있고 편리한 한방 의료서비스를 제공받을 수 있다. 본 논문에서는 심전도(ECG), 혈압, 맥박 등의 생체신호 측정센서를 이용한 센서네트워크 기반 u-Healthcare 시스템을 설계하고 구현하였다. 센서노드에서 게이트웨이를 경유한 생체신호는 healthcare센터로 전송되며, 질환별 건강관리 표준 프로그램을 통하여 생체신호를 분석하고 예측된 병증에 관련된 운동요법, 식이요법, 한방요법 등의 정보를 환자에게 피드백하여 건강관리를 할 수 있게 하였다.

The workflow, one of core features for modern business operation, models common elements and their relationships in business processes. The research is focused on how to adapt the workflow model to the healthcare examination which becomes popular these days. Especially, we intend to have fully automated process for healthcare examination by providing customers with PDA with RFTD chip. In order to realize this goal, this paper proposes the design of software architectures the class structures, and the definition of messages used for the system interactions. In other word, the paper shows the analysis of healthcare application in terms of service scenario and the design of workflow engine ant ubiquitous healthcare application under the Object-Oriented programming environment. the The result of the study may also enable the unmanned healthcare examination as well as ubiquitous based healcare examination sooner or later.

The importance of hi-tech communications technology including mobile or ubiquitous system and the related business field is currently expanding. In terms of wellness for enhancing quality of individual life, ICT technology became a requirement, not an option. The first purpose of this study is to identify factors that influence user's perceived usefulness & perceived ease of use related to the acceptance of TAM focused on ubiquitous fitness service through multiple regression analysis, thereby discovering important factors influencing consumer behavior. In conjunction with the result, the second purpose of this study has also its implication on the u-Healthcare system development using QFD. That is, this research is to propose the possibility of combining the external variables of TAM to u-Healthcare system service characteristics with user requirement reflected by using QFD method. Based on these results, the suitable system may be constructed and developed.

Studies on human-centered services are approaching their highest peak with the emergence of a new concept of the network environment, a ubiquitous environment. Among these ubiquitous service technologies, services related to health care are very closely related to the current social environment. In this paper, With social aging and changes in ubiquitous IT environment, studies on health care, which is among the essential application services and which has been defined as a key application technology, and studies related to it have been conducted. In addition, healthcare services, which are essentially applicable to the ubiquitous environment, were suggested by analyzing existing healthcare studies and drawing from them the requirements for such. This paper proposes management protocol for serious case except from health care research. This system is constructed database using RFID, it has location information. It provides procedures to consistently monitor the status of patients and process the outcome in real-time.

The ubiquitous healthcare environment is one of the systems that benefit from wireless sensor network. But one of the challenges with wireless sensor network is its high loss rates when transmitting data. Data from the biosensors may not reach the base stations which can result in missing values. This paper proposes the Health Monitor Agent (HMA) to gather data from the base stations, predict missing values, classify symptom patterns into medical conditions, and take appropriate action in case of emergency. This agent is applied in the Ubiquitous Healthcare Environment and uses data from the biosensors and from the patient’s medical history as symptom patterns to recognize medical conditions. In the event of missing data, the HMA uses a predictive algorithm to fill missing values in the symptom patterns before classification. Simulation results show that the predictive algorithm using the HMA makes classification of the symptom patterns more accurate than other methods.
