After-all some 38years chemical engineering and fluidization research, which was of course enjoyable, I found it'd be much more fun and of value if I tie myself realistically to people/nation tackling their socio technological problems. Then I was luckily able to engage in survival science/engineering study and JST-RISTEX's environment/energy/community program and also in teaching at School of Policy Science, Ryukoku University (Kyoto) for five years able to design the framework of my present work.
