Research paper : Analysis of synthetic approaches described in papers of the journal Synthesiology (N. Kobayashi et al.)−39−Synthesiology - English edition Vol.5 No.1 (2012) reviewed from the chemical and engineering aspects, laboratory level preparation method was completed as the important elemental technology, and commercialization was achieved through joint research with the catalyst producing company. Therefore, the elemental technologies broken down from the social demand had the multistep structure that was an aggregate of detailed elemental technologies. Since the lower level elemental technologies are solved by breakthrough type research and then are integrated, the overall scenario is the “strategic selection type + breakthrough type” synthesis (Fig. 2).Another example of this type is the “Establishment of compact processes” by Suzuki et al.[9] To respond to the social demand of emission control of the environmental load substance from the chemical process, the technology using supercritical fluid of water or carbon dioxide instead of an organic solvent, which was a technology that was theoretically possible but not readily realized, was reviewed by breaking down into individual elemental technologies. It was found that unnecessary reactions occurred before reaching the optimal condition due to slow reaction, and the rapid heating and pressurizing methods were developed to attain the optimal condition rapidly as the elemental technology, and this process was synthesized along with other peripheral elemental technologies. The breakthrough was the process called detuning that involved purposefully withholding the ideal condition to create the optimal condition.In the environment and energy field, since the goal is to fulfill the social demand by integrating the necessary elemental technologies, the synthesis is essential to meet the specific demand. In general, the strategic selection type scenario can be taken in the cases where the elemental technologies are identified by conducting strategic selection in the first stage and the results of R&D up to a point or their improvements to match the goal are used. This type of synthesis can be seen in three papers. On the other hand, in the case where there are major issues among the elemental technologies, which is shown in the low environmental load technology mentioned above, the breakthrough technology becomes essential, and the social demand can be met only if such breakthrough is realized. In these cases, the general scenario is the “strategic selection type + breakthrough type” synthesis, and there were three such cases.There were also two aufheben types and one breakthrough type. The categorization is shown in Table 1.(2) Life science fieldThe characteristic synthesis method in the life science (biotechnology) field is the cyclical development method. Suwa and Ono developed the comprehensive functional Fig. 2 Strategic selection + breakthrough type synthesis in the environment/energy fieldTable 1.
