Shinzo Kohiya received his PhD from Kyoto University in 1974. His reserach interests include kinetic studies on ionic polymerizations, development of soft rubbery materials of high functionality, structural studies on polymeric amorphous materials and their applications, and scientific elucidation of filler dispersion in rubbery matrix. He is currently a professor emeritus, Kyoto University. He is the author of several books, and about 350 papers which appearred in decent international journals. He won the Oenslager award from Society of Rubber Industry, Japan, in 1994. He has 23 years, 13 years and 3 years of teaching experiences at Kyoto Institute of Technology, Kyoto university, and Mahidol University in Thailand, respectively.Atsushi Kato rreceived his PhD from Tohoku University in 1985. His research interests include unusual stress-strain properties of natural rubber vulcanizates with high primary molecular weight, fatigue characteristics ofglass fiber reinforced polyamide, study on microfracture mechanism of glass fiber reinforced polycarbonate by using acoustic emission, optical transparency and silica network in cross-linked natural rubber as revealed by spectroscopic and three-dimensional transmission electron microscopy technique, reinforcement mechanism of carbon black (CB) in natural rubber vulcanizates, and so on. He is currently working on development of analysis technology of soft materials at the automotive analysis department of NISSAN ARC, LTD. He won the Materials Life Society Review Award from the Materials Life Society, Japan in 2009, and the Rubber-Technical Merit Award from the Society of Rubber Science and Technology, Japan in 2012. Yuko Ikeda received her Ph.D. from Kyoto University in 1991. The title of thesis was “Studies on Blood-Compatible Polyurethanes with Triblock Polyether Soft Segments”. Her research interests include fundamental studies on the sulfur cross-linking and reinforcement of rubbers by using new analytical methods. Characterization of natural rubbers are also studied by using synchrotron X-ray analyses. She is currently a professor at Kyoto Institute of Technology. She published 137 original papers, 67 review papers and 16 essays, and contributed to 48 books. She won the 29th Oenslager award for her study on “Fundamental study on cross-linking of rubber” from Society of Rubber Industry, Japan, in 2014. She has 31 years of teaching experience at Kyoto Institute of Technology.
