ABSTRACT
In this paper, an emergency telemedicine system was designed for the transmission of real-time multimedia for remote consultation, including radiological images, patient records, video-conferencing, full-quality video, ECG, BP, respiration, temperature, SpO2, systolic and diastolic pressures and heart rate. The standardized, modular, software-based design architecture, without resorting to external hardware compression boards, enables the low-cost implementation of the telemedicine system, using the unified, systematic and compact integration of multimedia on general personal computers. Experimental tests on local networks analyze the technical aspects of designed systems, and inter-hospital experiments demonstrate its clinical usefulness.

Asthma is a chronic disease, which requires a successive and long-term management. In this paper, we implemented a web-based caring system for a more effective management of the asthmatics. The service of this asthmatic-caring system targeted on both the doctor and the patient. The patient connects to the asthma management server through the Internet everyday and inputs his or her daily condition and dosage. Then the doctor will give a proper comment or order to the patient according to the data that patient has filled in. By merely connecting to this web-site, doctors can manage asthmatics everyday and the patient can be under the doctor's management without frequently visiting the hospital. The test verifying the user's satisfaction of the implemented system has been taken by both the doctor- and the patient-groups. The doctor-group pointed out the successive management, an easy inspection of the patient condition, and the accumulation of clinical data for future researches as advantages. The patientgroup pointed out being under the daily management without visiting hospital and the active attitude they can have toward their diseases as advantages.

Telemedicine is described as combination of topics from the fields of telecommunication, medicine, and information and literally telemedicine means medicine at a distance. In this study, we present a web based real-time telemedicine application(WEBRETA) that was designed for patients who needs diagnosis on the Internet. The WEBRETA system is supporting transmitting of MPEG-4 video format(640*480)that was appropriate for Internet and designed with ActiveX controls technology that is also suitable for telecommunication link such as ADSL, VDSL and Cable modem which are very popular communication link in Korea. To improve the reliability and the usefulness of this prototype we involved the PSNR method and subjective score measuring from doctors. Futhermore, we will evaluate the WEBRETA with various communication network environment to improve how this system can contribute the diagnosis of patients and to analysis.

Using a high bandwidth cellular communication network is appropriate to implement a high-quality mobile emergency telemedicine system. In Korea, the commercial service of CDMA2000 1X-EVDO has been providing since 2002. In this paper, we designed the system that transfers the biological signal and the video information of a patient simultaneously based on this CDMA2000 1X-EVDO network environment. In CDMA2000 1X-EVDO, the maximum speed of its reverse link can be observed within 153.6Kbps. Before the system design, several field tests had been performed using commercial CDMA2000 1X-EVDO reverse link with the UDP data segments. The test had been taken under several velocity and tunnel areas of Seoul. With the test result we implemented an efficient emergency telemedicine system fitted to the features of CDMA2000 1X-EVDO reverse link using UDP packets. Additional header information is added to the UDP packet data. With the header information the emergency system can transmits the ECG signal prior to the video data and controls the transmission error. The designed system has the ability to transmit both the biological signals and MPEG4 video of 640x480 spatial resolution at the same time. We set up the ambulance with this system and test it on the road.
