방송용 위성시스템과 디지털 영상 전송시스템을 이용한 원격강의의 효과 평가: 참가자 설문조사로 비교

초록

Background/Aims: Telemedicine is a useful tool for remote education to overcome limitations of location. We have shared medical knowledge by the use of a real-time, high quality digital video transfer system (DVTS). The study aim was to evaluate the use of the DVTS by viewer questionnaire. Methods: After an endoscopic live demonstration using DVTS and satellite broadcasting system (SBS), questions were provided for the degree of satisfaction about image and sound of the presentation. A questionnaire was composed of 11 questions concerning factors such as a comparison of image quality between the two systems. The preference between DVTS with SBS was analyzed. Results: For image quality, SBS was more preferable than DVTS (65.6% versus 16.7%). However, 16.7% found no difference between the use of DVTS and SBS. For the time delay between the image and sound, 62.5% preferred SBS and 11.5% preferred DVTS. The satisfaction for combining DVTS with SBS were 68% as good and 22% as very good. Conclusions: We have demonstrated the feasibility of telemedicine by the demonstration of a satisfactory teleconference, although DVTS was utilized as an assistant tool. DVTS should prove to be a promising tool as a useful and economic means to provide remote medicine.
