Abstract
There is great scientific progress in areas which combine knowledge and scientific paradigms coming from different scientific domains. We will discuss some examples of combinations between relatively close areas in Computer Media and Communication Sciences. We will also discuss examples like Bio-Informatics or Medical-Informatics which combine widely different areas. Some projects will be outlined demonstrating the problems but also the great potential of the approach. New carreer possibilities are open for people properly trained in these Bi-Tri Sciences.
