Preface
Knowledge, the object of knowledge, and the knower are the
three factors that motivate the action; the senses, the work, and the doer are
the three constituents of action.

From September 1996 to August 1997, we worked together at the
Delft Univetsity of Technology, The Netherlands, in order to realize future
wireless personal multimedia communications (WPMC). During our joint research period,
research and development were done on higher layers such as the media access
control (MAC) layer and the physical layer, and many researchers came from
Europe, Asia, the United States, and The Netherlands to work with us. We also
starred new projects and established a joint cooperation with several research
institutes, companies, and universities. Once a project is defined, many new
researchers are allocated. Among the researchers, some newcomers arc
occasionally involved. Moreover, most projects are time-limited. In this
situation, the answer to the question of how newcomers prepare to evaluate the
target is one of key issues to success in the time-limited project. We
considered the answer carefully.
