Outline of Final Research Achievements

As for the most of the decorated kofun, paintings or carving are applied directly on the surface of the soft and fragile stone and tuff stone which is often used for the stone chamber deteriorates easily due to condensation. Hence, for the preservation of these decorations, we examined the influence of the covering condition of the tumulus mound upon the condensation inside the stone chamber.
Furthermore, we examined an environmental control methods by numerical analysis to inhibit the condensation upon the stone chamber. It is suggested that with the shelter which covers the stone chamber and by the appropriate ventilation to exhaust the moisture generated from inside the stone chamber, condensation inside the stone chamber would be reduced effectively.
