We introduce a new multimedia telemedicine system which is called Telemedicine for Real-time Emergency Multi-consultation(TREM), based on multiple connection between medical specialists. Due to the subdivision of medical specialties, the existing one-to-one telemedicine system needs be modified to a simultaneous multi-consulting system. To facilitate the consultation the designed system includes following modules: high-quality video, video conferenceing, bio-signal transmission, and file transmission. In order to enhance the operability of the system in different network environment, we made it possible for the user to choose appropriate data acquisition sources of multimedia data and video resolutions. We have tested this system set up in three different places: emergency room, radiologist's office, and surgeon's office. All three communicating systems were successful in making connections with the multi-consultation center to exchange data simultaneously in real-time.

In an emergency telemedicine system such as the High-quality Multimedia based Real-time Emergency Telemedicine(HMRET) service, it is very important to examine the status of the patient continuously using the multimedia data including the biological signals(ECG, BP, Respiration, $SpO_2)$ of the patient. In order to transmit these data real time through the communication means which have the limited transmission capacity, it is also necessary to compress the biological data besides other multimedia data. For this purpose, we investigate and compare the ECG compression techniques in the time domain and in the wavelet transform domain, and present an effective lossless compression method of the biological signals using PEG Huffman table for an emergency telemedicine system. And, for the HMRET service, we developed the lossless compression and reconstruction program or the biological signals in MSVC++ 6.0 using DPCM method and JPEG Huffman table, and tested in an internet environment.

Telemedicine system means a remote support system among 4 remote telemedicine services of u-Health. A currently available service in Korea is the one checking and maintaining patient's status and supporting in emergency through video communication between an ambulance transferring patients and hospital under HSDPA and WiBro environment with coding of MPEG-2 and MPEG-4. With that, this paper improves the stability of the current telemedicine system service of ambulance confirms the improvement compared to the old system by generating a system communicating by RTP/RTCP under coding process through H.264/AVC after converting RGB video to YUV in order to improve network efficiency.

This research intended to analyse the perception level of seafarers in order to propose enhancement of health management for seafarers and improvement of marine telemedicine assistance system. To this end, questionnaire survey was conducted for 422 seafarers in relation to current status of utilizing Emergency Medical Advice by radio(EMAR). By trading area, experience of benefiting EMAR by coastal seafarers was higher than that of ocean-going seafarers. By kinds of ships the rate of utilizing EMAR by fisherman was higher than that of seafarers of merchant ships. The level of satisfaction on the EMAR was 14.9% and regarded to be very low while the answering rate of necessity and urgency toward introducing marine telemedicine assistance system for the future through utilizing telemedicine equipment what is called U-helath including motion pictures information was very high. The answering rate of willingness to provide their personal health information positively when introducing marine telemedicine system was very high(97.4%). It is thus necessary to permit marine telemedicine service system, establish service model of marine telemedicine through conducting demonstration projects, promote marine telemedicine actively at the level of government, etc.

최근 육상에서 원격진료에 대한 많은 연구와 기술개발이 수행되어 왔으나 해상에는 적용되지 않고 있다. 본 논문에서는 해상의 선박에서 긴급한 응급의료 지원상황이 발생했을 때 환자의 생체정보를 측정하여 원격지에 있는 의사에 게 전달하고 진료 받기 위한 원격 진료 시스템을 설계하고 구현하였다. 현재 해상에서 응급상황이 발생 시 주로 무선통신이나 위성 전화를 통한 단순한 문답에 의한 의학 자문에 의존하고 있다. 본 논문에서는 이를 개선하기 위해 전문적으로 진단에 필요한 환자의 기초 신체상태 즉, 혈압, 맥박, 호흡, 심전도, 체온 및 영상 등을 선박 내 현장에서 측정한 후 전문 의료진에 원격 전송함으로써 보다 정확한 처방이 가능하고 보다 높은 의료서비스를 제공할 수 있도록 개발하였다. 개발된 시스템으로 해상상의 응급환자에게 의료 서비스의 질을 높여 응급상황에 적절히 대처할 수 있다고 본다.

Expansion and spreading of marine telemedicine is rather restricted due to the conflict of laws relating to medical service and lack of provisions in the Seafarers' Act, Medical Service Act, etc. Thus, this study is intended to reveal the current status and problems of marine emergency medical advice system for the furtherance of health care of seafarers and emergency medical assistance conditions and deduce relevant proposals for legislative improvements thereof in order to resolve underlying problems and issues. The results of this study can be summated as follows. First, in respect of directions to provide marine emergency service based on marine telemedicine system, emergency radio medical advice system needs to be strengthened to meet domestic and international instrument, marine telemedicine system needs to be provided through integrating u-Health technology and special marine medical center needs to be established. Second, regarding directions to provide health promotion service based on the marine telemedicine system, a new process of health care service for seafarers needs to be devised and provided involving seafarers' life cycle covering from prior to boarding to after leaving a ship. The conclusions of this study can be given as follows. First, the following new provisions need to be introduced in the Seafarers' Act. (1) The Minister of Oceans and Fisheries and a shipowner shall conduct matters pertaining to preventive health promotion and care for seafarers; (2) a provisions regarding establishment of seafarers' health promotion center by the Minister; (3) a special exemption permitting marine telemedicine service and qualification requirements for marine telemedicine assistant; (4) shipowner's obligation of carrying seafarers' health measuring equipment on board. Second, the relevant provisions regarding medical care persons needs to be revised in such a way that master or chief officer shall be appointed to be in charge of medical care on board. Last but not least, it is also essential to amend and update the minimum standards on drug and medicines to be carried on board and medicine chest and equipment on board.

IT 및 통신 기술의 발달로 의료시스템 분양에 적용하여 원격진료 서비스를 제공하게 되었다. 원격진료 서비스는 인력 및 장비가 부족한 보건소, 학교, 도서지역 등에서 원격진료 서비스를 이용하여 2, 3차 의료기관의 의료진과 원격 자문과 진단 서비스를 통하여 양질의 서비스를 받을 수 있다. 원격진료를 이용하는 환자와 의료진은 다양한 통신망을 사용하여 원격진료 서비스를 이용 할 수 있지만, 통신망에 따라 대역폭의 차이와 공인 IP, 사설 IP의 특성으로 인하여 원격진료 서비스를 원활히 이용하는데 어려움이 있다. 따라서 본 논문에서는 다양한 네트워크 환경에서도 원격진료 서비스를 원활하게 이용 할 수 있고, 의료진과 환자 사이의 연결 리스트를 관리하여 효율적으로 원격진료 서비스를 제공할 수 있도록 다중접속 제어서버를 구현하였다. 다중접속 제어서버는 환자와 의료진의 리스트관리, 네트워크 타입, 사용자 장치타입을 이용하여 최적의 정책을 결정하여('Flowing'과 'Bypassing') 서비스하고, 사용자(의료진과 환자)의 연결 정보를 모니터링 할 수 있는 시스템을 구현하였다.

In emergency telemedicine system based on wireless communication system with limited transmission capacity, it is necessary to transmit the biological data (ECG, BP, Respiration, $SpO_2$) of the patient continuously and reliably in real time. For this service, it is necessary to data compression and error control. In this study, we designed an protocol for error control in application layer and implemented it on the biological data transmission program for an emergency telemedicine system based on wireless data communication system.
