We propose the various Telemedicine applications on the DooRae (Distributed Object Oriented Multimedia Application Crafting Environment for Collaboration) framework(or platform). DooRae-Telemedicine supports the application development of the collaborative multimedia environment connected with the network(LAN, MAN, WAN) in the CBM(Computer based Multimedia) based. Also, it is not restrict on space between a doctor(s) and a patient(s) into cyberspace made by network. The kinds of Telemedicine in this paper have different distinction, and the development of these application system is possible on DooRae environment. DooRae-Telemedicine has a interaction, various communication type, a question and an answer, multi-session, application sharing and whiteboard which resembles chalkboard. Also, various supplementary functions such as video conference and voice conference for DooRae-telemedicine are what makes face-to-face medicine effective. Also it supports real or non-real type. The operating system developed on windows 95 and windows NT This research has been done creating multimedia-based telemedicine system for home PCs in network environment. Most of telemedicine used hardware and exclusive line of high cost as CATV broadcasting technique. But DooRae-telemedicine will contribute to change the Home-PC for better use of collaborations among doctor and patients through various modes o interactions in cyberspace.
