  • In this paper, I will report the cases of children who are able to study at kindergarten or elementary school because they learned how to move by themselves using a moving aid before school age, and I will also discuss the development of a mobility device which allows severely disabled preschoolers to practice moving around by themselves safely and easily at home and institutions.

  • This study aims to develop a current building condition database of an important folk culture village of South Korea considering their fire spread risk. We have selected a folk cultral village, and conducted field survey to reveal structure of buildings, materials of building wall, and roof style which make us understand current vulnerability of the village to fire spread. As a result, we made a current building condition database with map, which showed that the village had mixture of reinforced concrete and wood. Besides, we proposed a conceptual idea to prevent from large fire accident in the village.

  • Thermoelectric conversion efficiency of thermoelectric elements can be increased by using a structure combining n-type and p-type semiconductors. From the above point of view, attention was directed at ZnO as a candidate n-type semiconductor material and investigations were made. As the result, a dimensionless figure of merit ZT close to 0.28 (1073K) was obtained for specimens produced by the PCS (Pulse Current Sintering) method with addition of specified quantities of $TiO_2$, CoO, and $Al_2O_3$ to ZnO. It was found that the interstitial $TiO_2$ in the ZnO restrains the grain growth and CoO acts onto the bond between grains. The influence of the inclusion of $TiO_2$ and CoO onto the sintering behavior also was investigated.
