심전도 데이터 압축에 관한 연구는 참고문헌에서 보는 바와 같이 선진외국에서는 꾸준히 이루어져 왔지만, 국내에서는 활발하지 못하다. 경미한 심장질환자들이 항상 병원내에 입원하여 갇혀있지 않고 자유롭게 사회활동을 할 수 있도록 무선 이동통신을 통한 원격 진단시스템도 연구되고 있으며, 적어도 위급한 상황은 자동 판별하여 경고(warning)해 주고 즉시 의료혜택을 받을 수 있게 해 주는 것도 연구대상이 되고 있다[1]. 국가가 발전해 나가면서 경제규모에 비례하게 의료기술도 발달하게 되고 국민들의 건강에 관한 관심도 높아지는데, 특히 식생활의 서구화에 의해 심장질환자가 급증하고 있는 시점에, 심장질환자들의 치료와 구명차원에서 판단하건데, 이러한 분야 연구의 필요성이 있다고 본다.

In this paper, we proposed a multi-agent based healthcare system (MAHS) which is the combination of medical sensor module and wireless communication technology. This MAHS provides wide services to mobile telemedicine, patient monitoring, emergency management, doctor's diagnosis and prescription, patients and doctors, information exchange between hospital workers in a long distance. Also, MAHS is connected to Body Area Network (BAN) and a doctor and hospital workers. In addition, we designed and implemented extended JADE based MAHS that reduces hospital server's burden. Agents gather, integrate, and deliver the collected patient's information from sensor, and provide presentation in healthcare environment. Proposed MAHS has advantage that can handle urgent situation in the far away area from hospital like Islands through PDA and mobile device. In addition, by monitoring condition of patient (old man) in a real time base, it shortens time and expense and supports medical service efficiently.

This paper describes the implementation of a 3 channel ECG monitoring system. This system consists of an IBM-PC and simple accessory only. A PDTS (parallel data transmission system ) was designed to do monitor the data being operated with no effect and no exchange of software and hardware on the main transmission system in LOCAL mode. And it receives patient's ECG data from EPTS ( ECG processing and transmission system) of distant region. It provides on-line ECG waveform display, waveform storage, recall and editing the waveform. We have implemented the monitoring system by tw methods, and with system, we could directly monitor the EPTS and also receive the data from the remote ㅁe잉ion. This system was tested by experiments and examined its practical use.

To order to remain competitive, a manufacturing company need to maintain the optimal condition of its manufacturing system. Machine tools as an important element of a manufacturing system comprises complex mechanical as well as electronic components. So, diagnosing the troubles of machine tools is tricky process which requires a lot of experience and knowledge. Since providing machine tool users with necessary serices at the right time is very difficult,a remote diagnosis system is to be regarded as a good alternative, with which users can diagnose and fix the machine troubles. This paper presents a method to implement a remote machine tool diagnosis system using the world wide web technology and backward reasoning expert system.

This paper presents a remote patient monitoring system for diagnostic pure-tone audiometry. A pure-tone audiometer was developed for basic hearing screening; its performance was evaluated according to international standards in terms of linearity, accuracy, and total harmonic distortion. Pure-tone audiometry has a maximum hearing level of 104.9 dB HL that is comparable with other commercial products. The audiometer shows satisfactory linearity with a deviation of ${\pm}0.4dB$, an accuracy of ${\pm}0.025%$, and a total harmonic distortion (THD) of 0.21%. The remote patient monitoring systems include remote control devices based on wide area network (WAN) connections and an audiometer connected in series. Through experimentation, we successfully performed real-time diagnostic communication without delay in transferring audiometric data. This system is expected to supply domestic equipment in the audiometric market and to improve the quality of life of patients in non-clinical environments.

With the rapid growth of the up-to-date smartphone and wireless network technologies, huge and various types of smart applications using these technologies are actively developed recently. Especially, multiplex types of smart applications using smartphone are developed and diffused with the rapid development of the ubiquitous sensor network technology using various sensors and the mobile computing technology that enables us to get network services at any time in any places. In this paper, we design a smart application that can accurately diagnose and process the current state of the local environment, objects, and persons remotely based on the context information such as local ecology, circumstances, medical or healthcare records and realtime sound or motion pictures using up-to-date samrtphone technology on the USN based mobile computing environment.

개인 휴대단말기로부터 측정된 생체정보 데이터가 PHR에 데이터베이스화되기 위해서는 응용 계층 표준 프로토콜인 HL7 CDA 표준에 따라야 한다. 하지만 국제 표준 HL7 CDA는 병원 시스템 간 의료정보 전달을 위한 프로토콜이기 때문에 개인 건강 기기로부터 측정된 생체 정보가 IEEE 11073 PHD 표준에 준하여 전달하더라도 HL7 CDA 프로토콜과 연동될 수 없다. 즉, 모바일 단말기 기반의 u-헬스케어 모니터링 서비스를 위해서는 IEEE 11073 PHD와 HL7 CDA 간 메시지 변환 게이트웨이가 필요하다. 이에 본 논문에서는 개인 휴대단말기를 통해 원격지에 있는 의료진이 사용자의 생체데이터를 실시간 관리하기 위해 ISO/IEEE 11073과 HL7 CDA 간 메시지 변환 게이트웨이 및 HL7 기반 진단지원시스템을 설계하였다.
