고령화 사회의 웰빙트렌드와 생활습관에 의해서 의료서비스는 병원 중심의 치료서비스에서 개인과 의료인이 상호 긴밀하게 협력하여 질병의 예방, 관리, 건강증진 등을 제공하는 u-의료서비스 트렌드로 급속히 변화되고 있다. 최근 Biotechnology (BT), Information technology (IT)의 발달은 다양한 소형 센서 및 기기 개발을 가능하게 하고 있으며, 이렇게 측정한 환자의 데이터가 병원과 의사에게 전달되도록 함으로써 언제 어디서나 검사와 진료가 가능하도록 하는 유헬스케어 시스템이 대두되고 있다. 만성질환에 대한 유헬스케어 분야는 이제 단순한 의료차원이 아니라, BT 및 IT부문에 각각 굉장한 산업적 파급효과를 일으킬 수 있어 차세대 성장동력사업으로 발전할 수 있을 것으로 기대하고 있다.

최근 유비쿼터스 시대에는 사용자의 편의성과 보안을 위주로 한 시스템들이 등장하고 있다. 병원에서는 컴퓨터를 이용하여 차팅을 하는 EMR 시스템을 도입하여 병원 내에서의 사용자 정보의 공유가 쉽게 이루어지고 있다. 사용자 중심의 전자ID지갑은 하나의 ID로 여러 사이트의 가입과 정보공유를 할 수 있다는 편리성과 개인정보보호 서버로 인한 피싱과 파밍으로부터 안전하다는 보안성을 지니고 있다. 이에 사용자는 전자ID지갑의 기능을 EMR시스템과 연동하여, 사용하는 측과 사용 받는 측 모두 효율적인 관리를 할 수 있는 기술이 필요하다. 본 논문에서는 이러한 전자ID지갑과 U-healthcare 시스템의 기능을 이용하여 사용자가 효율적인 서비스를 받기 위한 시스템과 보안관련 사항을 제안한다.

A general medical information service in hospitals recently has been rapidly developed in the effective patient management due to the digitalization. In addition, the hospitals make an effort to support the medical information service in ubiquitous environment. A key requirement in ubiquitous environment is the ability to communicate between the image viewer system using the DICOM standard and a server system to support the medical information service. This paper describes a remote networking system based on the mobile terminal with RFID technology for the medical information service. In order to apply the overall configuration, we first implemented the DICOM viewer system, configured the database to store the patient information, and realized the server/client networking system in mobile terminal environment. In particular, this paper showed the capability for the medical image-based communication as well as the text-based communication.

In this paper, we propose a mobile telemedicine system that acquires more easily and analyzes individual's bio-signal using PDA. It is not easy for modern people who live busily, disabled patients, or old people to visit hospital. The major goal of this study is to implement the mobile telemedicine systems that the captured bio-signal from remote hospital or other medical treatment device is transmitted via Bluetooth module in ubiquitous environment, PDA with built-in Bluetooth module receives its data and displays on the screen in various form. By implemented systems, it is possible to compare current bio-signal with historical bio-signal and analyze bio-signal, and it is able to make a self diagnosis and it is available to be examined and treated remote diagnosis by sending stored bio-signal to a medical doctor.

Today, Hospital Information System that integrates ubiquitous technologies are introduced in limited basis due to problems like standardization and limits on medical use, where responsibilities lie, legal safeguard on transmission, invasion of privacy etc. Particularly, problems like absence of tag design suitable for medical environment, compatibility issue with previous medical information system. In order to solve such problems, we have designed medical tags for the first time that are consistent with future ubiquitous environment by deciding on medically suitable field with 96bit tag offered by EFC as its base. Second, improving on previous multi-tag recognizing crash prevention algorithm, we have designed a priority anti-collision algorithm that reflects priorities on the needs in medical environment.

The purpose of this study is to suggest hospital clothing design which reflects ubiquitous info-communications technology as changing hospital environment in the information-oriented era of the 21st century. The methods of this study are documentary research of previous studies, observation research and deep interviews. Seoul national university hospital is selected as a target of observation for this study. Doctors, nurses, pharmacists, and patients who are the representative jobs in the hospital are interviewed from on July, 13, 2006 to on August, 1, 2006. According to observation research, the computers, OCR, and PACS are applied from registration to dosage through all courses of diagnosis. However, the most inconvenient problems to patients are the location of medical offices and confusion of reservation. Also, the needs and inconveniences of doctors, nurses, pharmacists, and patients are almost solved by using RFID technology as a result of deep interviews. They prefer wearing devices as an accessory to wearing devices as a clothing directly. In conclusion, suggested UFC design for hospital clothing with info-communications technology promotes efficiency, accuracy, convenience of work to medical personnel in changing hospital environment as the flow of the information-oriented era of the 21st century.

유비쿼터스 핵심 기술 중 하나인 RFID 기술은 의료산업분야 전반에 걸쳐 활용이 증가하고 있으나, RFID 기술은 태그의 내용을 리더기를 통해 무선주파수로 식별하는 기술임으로 태그의 크기와 위치에 따라 태그의 인식률에 대한 차이가 크기 때문에 태그의 인식률의 성능이 입증되지 않아 도입의 큰 어려움을 겪고 있다. 본 연구에서는 사물의 다중인식이 가능한 RFID 시스템을 의약품 창고 관리에 적용하기 위하여 병원 내에서 사용하는 기밀용기에 대한 태그 부착위치와 크기에 대한 인식률 연구를 수행하였다. 실제 병원 약제실의 책장을 모델링하여 Test Bed로 구축하였으며, 구축된 Test-Bed를 통해 병원에서 사용하는 의료용 기밀용기에 태그를 부착하여 최적의 위치를 찾고, 리더기의 최적의 위치에 대한 연구를 수행하였으며, 인식률 향상을 위한 최적의 조건을 제공하고자 한다.

The recent medical treatment guidelines and the development of information technology make hospitals reduce the expense in surrounding environment and it requires improving the quality of medical treatment of the hospital. That is, with the new guidelines and technology, hospital business escapes simple fee calculation and insurance claim center. Moreover, MIS(Medical Information System), PACS(Picture Archiving and Communications System), OCS(Order Communicating System), EMR(Electronic Medical Record), DSS(Decision Support System) are also developing. Medical Information System is evolved toward integration of medical IT and situation si changing with increasing high speed in the ICT convergence. These changes and development of ubiquitous environment require fundamental change of medical information system. Mobile medical information system refers to construct wireless system of hospital which has constructed in existing environment. Through RFID development in existing system, anyone can log on easily to Internet whenever and wherever. RFID is one of the technologies for Automatic Identification and Data Capture(AIDC). It is the core technology to implement Automatic processing system. This paper provides a comprehensive basic review of RFID model in Korea and suggests the evolution direction for further advanced RFID application services. In addition, designed and implemented DB server's agent program and Client program of Mobile application that recognized RFID tag and patient data in the ubiquitous environments. This system implemented medical information system that performed patient data based EMR, HIS, PACS DB environments, and so reduced delay time of requisition, medical treatment, lab.

ularly, a points of view Health-care system, it can reduce costs and efforts in order to management of patients. However, Health-care system keep a level of service for person and extends of hospital inner parts system. Although the rate of an addict grow by alcoholic but it is difficult to manage and diagnosis because of patient data gathering. Therefore in this thesis, it is proposed to patient data gathering and monitering method in u-zone. It can collect patient data by pulse, temperature and acceleration sensor and it can diagnosis correct based on emotion change data.

RFID and USN are major technology in Ubiquitous. RFID is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders through RFID reader. USN is wireless sense network and monitoring environment conditions that is temperature, noise, pressure, oscillation. In this paper, we propose wireless sensor network system that is monitoring to optimize environment conditions.
