Based on the hadro-molecular simulation based on an event generator URASiMA, we evaluate the coefficients for a hot and dense hadronic fluid.To appear in the proceedings of "International Workshop On Hadron Physics and Property of High Baryon Density Matter" held at Xian on Nov.22-25, 2006High Energy Physics - PhenomenologyNuclear Theorytext
