This paper presents the test-tube experimental results of thermal properties of TMA clathrate compounds for latent heat storage applications. The results are : ⅰ) subcooling in TMA clathrate compound is the lower than water, ⅱ) Phase change temperature in TMA clathrate compound is the higher than water. ⅲ) Latent heat of 25wt% TMA clathrate compounds of 220.4kJ/㎏K appear to be maximum. ⅳ) Comparing with water, volume of TMA clathrate compounds decreased as the phase change. ⅴ) TMA clathrate compounds precipitated because of increase of density as phase change. Thus, TMA clathrate compounds are found to be the promising compounds for the heat storage from the viewpoint of thermal property.

This study deals with two topics on scour-protection method: field experiments laboratory experiments. Field experiments for scour protection method showed that the effectiveness rap-rap is highly dependent on the prediction of flow velocity and that debris deposited in front of bridge piers increase the dimensions of scour hole. The laboratory experiments were performed in order to compute the effectiveness of several protection methods. Among the protection methods tested in this study, gabion is proved to be most effective counter measure against scouring.
