언제 어디서나 예방, 진단, 치료, 사후 관리의 보건 의료 서비스를 제공하는 Ubiquitous-Healthcar(U-HC)는 최근 초보적인 단계로 IT기술과 의료 시스템이 결합된 원격 또는 재택 진료 시스템이 선을 보이고 있다. 하지만 원격 의료 시스템의 개인 신상 및 바이오 유출은 환자의 프라이버시 침해의 가능성을 내포하고 있다. 따라서 본고에서는 원격 의료 정보 시스템의 인증을 강화하기 위하여 Telebiometrics X.tsm과 X.tai 표준을 기반으로 하는 바이오 인식 기반 원격의료 정보 시스템의 사용자 인증 모델의 예를 제시하고 Telebiometrics의 X.tpp를 기반으로 시스템에서 발생 할 수 있는 취약성 및 위협을 분석한다.

This paper introduces an implementation of the diagnosis software for CC-NUMA systems. The CC-NUMA architecture is composed of two or more SMP nodes installed with the specialized hardware to provide cache-coherent operation and the high-speed interconnection network to connect each node, it enables both the high performance and the high scalability. While the CC-NUMA system provides the single system image in the operating system aspect, it should be considered the multiple systems by the diagnostic software. Thus it is difficult to diagnose and manage CC-NUMA system using commercial administration software due to characteristics of the complicated architecture. The remote diagnosis and management are also required with a view to reduce Total Cost of Ownership. In this paper, we design diagnostic software to manage CC-NUMA server system, and propose its mechanism in client-server manner to support remote administration. Additionally, we use the Java-based user interface to enlarge an administrator's accessibility.

A u-healthcare remote diagnosis system is proposed for chronic disease and medical vulnerable groups check the health systematically and support for the most optimal environment to improve the quality of life. The u-healthcare remote diagnosis system using wireless measure the thoracic sound in the chest. And this is demonstrated that the system using radio frequency is not be affected by the electromagnetic wave with the use of an experiment and by confirming that this u-healthcare remote diagnosis system can not affect the doctors and the patients.

Along with the aging of the population, the number of dementia patients is increasing, and the social and economic burden is also increasing. Currently, the effective way to manage dementia patients is to identify patients with dementia early. However, in rural and island areas where medical staff are scarce, there is a problem that it is difficult to visit a hospital and get an early examination. Therefore, we propose a remote early detection system for dementia to solve the problems. The remote dementia early diagnosis system is a system that allows a patient to receive examination and treatment from a remote dementia expert using remote medical technology based on real-time image communication. The remote early diagnosis system for dementia consists of a local client system used by medical staff at health centers in the island, an image server that transmits, stores and manages images, and an expert client used by remote dementia experts. The local client subsystem satisfies the current medical law's remote collaboration by allowing the patient to use it with the health center's medical staff. In addition, expert clients are used by dementia experts, and can store/manage patient information, analyze patient history information, and predict the degree of dementia progression in the future.

In this paper, we describe an abvanced medical diagnostic system using multimedia technologies in netwok environments. In the system, docotors in remote sites perorm medicl diagnosis by exchanging information about patients and 3-D medicl images of malfunctioning body parts, which are reconstructed from 2-D images such as MRI, CT, CR, Angio. The diagnosic conferencing system controls the conferencing process by exchanging audio, information about patients, 3-D medical images and control data. 3-D medicl images are reconstructed by a ray casting method that uses an nalytical integration. Medical databae conists of absic information about patients, Information about medicl images, users, results of dianosis.

초고압 선로에 대한 풍부한 진단 경험과 축적된 Know-how를 바탕으로 선로의 이상유무를 원격으로 진단, 감시하는 On-line PD Monitoring System을 개발하였다. 초고압 선로의 이상 유무를 활선상태에서 정밀하게 진단할 수 있는 전기적인 측정방법으로 부분방전이 유일하다. 그러나 부분방전 신호는 미약하고 주위 노이즈와 구분이 어렵기 때문에 측정 뿐만 아니라 분석하기가 어렵다. 부분방전 측정 장비는 이러한 노이즈를 효과적으로 제거하고 측정된 신호를 의미있는 정보로 가공하여 사용자에게 제공해 주어야 한다. 본 논문에서는 이러한 조건들을 충족하는 고성능의 원격 진단시스템에 관하여 서술하였다.

본 논문에서는 중수로 원자력발전소에서 사용되는 핵연료 교환기 브리지의 상태를 감시하는데 필요한 진단 방법을 도출하였다. 핵연료 교환기는 고방사능 지역에서 작동하기 때문에 신호의 취득은 원격에서 비침투적으로 이뤄져야한다는 제약이 있다. 따라서 비침투적으로 원격에서 측정 가능한 신호들이 선정되었고 선정된 신호를 이용하여 정확한 진단을 위해서 필요한 여러 가지 진단 신호들의 장단점을 비교하였다. 진단 신호로는 모터의 출력 토크를 선정하였고 진단 신호의 타당성을 모형 브리지를 대상으로 수행한 실험을 통하여 검증하였다. 그리고 마지막으로 다양한 환경에서 실험을 하여 브리지의 작동 특성과 결함과 진단 신호와의 관계를 살펴보았다.

Radiologic images are widely used in hospitals for diagnosing and treating patients' diseases. The radiologist accurately reads radiologic images, and thus helps diagnose patients correctly. The number of radiologists is much smaller than is necessary, however. In some small or rural hospitals, there are no radiologists residing there. In these cases, correct diagnosis and treatment are infeasible. Also, radiologists are not resident at hospitals all day long. Thus, emergency patients would suffer from the absence of radiologists at night. XRay21 Inc. and Data & Knowledge Engineering Lab. at Kangwon National University have been working together since 2000 in order to alleviate the problems above. Currently, the advances of the computer and network technology make it possible to connect a lot of radiologists and hospitals together through the Internet. By fully utilizing the Internet environment, we have developed an Internet-based medical diagnosis system, thus permitting remote diagnosis of radiologic images. This paper presents the technical experiences obtained in developing the system.

Data transmission via the car driver's tethered smart phone may have a volume-dependent billing in case car driver' phone transmits data in real-time to the remote data center. The on-board diagnosis data generated are temporary stored locally to mobile remote diagnosis application on the car driver's phone, and then transmit to the data center later when car driver connects to the Internet. To increase the easiest of using the remote vehicle application without blocking other tasks to be executing on the cloud, node.js stands as a suitable candidate for handling tasks of data storage on the cloud via mobile network. We demonstrate the effectiveness of the proposed architecture by simulating a preliminary case study of an android application responsible of real time analysis by using a vehicle-to- smart phones applications interface approach that considers the smart phones to act as a remote user which passes driver inputs and delivers output from external applications. In this paper, we propose a study on development of Remote Vehicle fault diagnostic system features web server architecture based event loop approach using node.js platform, and wireless communication to handle vehicle diagnostics data to a data center.
