The results of special research project carried out for "Molecular approaches to non-equilibrium process in solution" were presented during the 42nd Yamada Conference on "structure, fluctuation and relaxation in solution" which was held from 11-15 December, 1994. The following topics were discussed at the conference: 1. Solvation dynamics. 2. Relaxation, fluctuation and reaction dynamics. 3. Dynamic structure and reaction mechanism in solution. These topics were the main concern of this conference.
