in Chapter 2, it may be said that the scenario is a kind of strategy to realize societal value by methods of science and technology, which is an important point for creating innovation. Authors describing processes and results of science and technology in the existing scientific journals, however, are not requested to describe the scenarios in their papers. The scenarios are not described often in the technical reports, "Giho," published by companies, either.The Editorial Board of Synthesiology started the journal assuming that the scenario plays a central role in synthetictype research and that it could be described by researchers verbally (using languages) and visually (using figures). Thus the editorial board requested the authors of the journal to describe scenarios in their own papers. This was an unprecedented attempt having never been made by the conventional scientific journals. Synthesiology has been published for eight years during which more than a hundred original papers have been issued. [1] We investigated those papers to see what role the scenarios played in synthetic-type research and how the scenarios were described verbally and visually. We attempted to see whether the assumption of the Editorial Board was valid.In Chapter 2, characteristics of synthetic-type research are clarified in comparison with those of the analytic-type. Then the first hypothesis that the scenario plays a central role in synthetic-type research is presented.In Chapter 3, the scenarios in synthetic-type research are described as having common and general characteristics. Then the second hypothesis that the authors of synthetic-Scenario in synthetic-type research: its role and description
