The simulation for medical and healthcare applications has recently been employed in our country in medical colleges for students' educational purposes. In terms of simulation, aviation, nuclear experimentation, as well as banking services have employed their own simulation programs. In the medical field, there are macro- and microsimulations. Full-scale human simulator and part task trainers belong to macrosimulation, and PC-based virtual realties belong to microsimulation. Both are very effective educational tools to bridge the medical knowledge to clinical practices. In simulations the role of the facilitator is very important and most learning activities are accomplished during "debriefing." Nowadays some centers in our country are introducing medical simulation. An increasing attention to simulation technologies would be critical for the dissemination of the concepts and their applications.
