Rotterdam: Erasmus Plus BV, OECR ISBN 90-9016127-9 ; Traditionally medical specialists attended seminars organized by clinical university departments of the K.U.Leuven Medical Faculty. However due to increasing travel and traffic problems the Pentalfa project was initiated in an effort to replace face-to-face seminars. We applied ISDN-videoconferencing technology to interconnect the video and sound signals of the different sites in real time. In all sites the session could be followed on two screens. On one screen, either the speaker/moderator or person involved in dialogue at a remote site could be seen or whatever else was being sent via videoconference. On the second one, which was linked to a multimedia computer, digitized images are projected. A voting system was used to interconnect all sites and allowed the participation in the various voting opportunities, which occurred during each session. For each session, a topic within a specific discipline was chosen and treated in a multidisciplinary way. The Pentalfa project was initially planned for a period of 3 years. During each academic year, 2 to 3 periods of 8-9 sessions each were organized (total of 74 session). A questionnaire, completed with open questions, was given to all participants (over three years 13 489 participants). 28.2 % of the questionnaires were returned. We reached 64.6 % male and 35.4% female participants with the program. The percentage female participants was higher at the central than at the guest sites. The mean age of the participants was 37.7 years. Male participants were older than female. At the central location the mean age was lower than at the guest locations. The percentage female participants decreased in the older age groups. Timesaving was an important goal for starting up the project. Nearly 90% of the public at the guest sites said they saved time by attending the session. The averaged time ...
