There is a wide gap of understanding modern history of East Asia by Koreans and Japanese people. It sometimes prevents two contries from improving the relationship. The aim of the present paper is to clarify such a gap in order to open the mutual educational horizon. The focus is a gap of understanding the separation and reunification of Korean Peninsula. The author summarizes recent surveys on mutual recognition between the two contries. Japanese indifference and ignorance of history and Koreans misperception were analized. By pointing out both Japan's and Korea's responsibility in the separation of Korean Peninsula, the present paper proposes the Japan's task and role for the reunification of North and South Korea to establish the peace of East Asia.

The present author visited El Salvador in August, 2007. In El Salvador, even the present, some workshops produce roof-tiles with craft of “Spanish roof-tiles” introduced by Spanish people. Current houses in El Salvador are roofed with concave flat-tiles, on the other hand eave tiles were not observed in this visit. As for the craft of roof-tiles production, workshops produce tiles with a table which make a tile concave. The structure of kilns built of bricks, with holes connected to the chamber for firing is similar to the structure of Japanese updraft kilns with roaster. This article shows results of ethnological researches which taken at 3 roof-tiles workshops in El Salvador. These results not only contribute to Salvadoran archaeology and ethnology, but also become ethnological data for the study about history of Japanese roof-tile production.

Detailed rupture processes of six intraplate earthquakes in Japan, the 1961 Kitamino earthquake, the 1969 GifuKen-Chubu earthquake, the 1974 Izu-Hanto-Oki earthquake, the 1975 OitaKen-Chubu earthquake, the 1980 Izu-Hanto-Toho-Oki earthquake, and the 1984 NaganoKen-Seibu earthquake, are compiled and compared to each other to make clear common features of an earthquake rupture process. The rupture processes are obtained by waveform inversion using strong motion seismograms in previous studies. Five of these rupture processes are also compared with distributions of precisely determined aftershocks. Earthquakes with relatively smooth rupture propagation, such as the 1974 Izu-Hanto-Oki earthquake and the 1961 Kitamino earthquake, represent smoother slip distribution than earthquakes with relatively irregular rupture propagation, such as the 1969 GifuKen-Chubu earthquake and the 1980 Izu-Hanto-Toho-Oki earthquake. It is also recognized that aftershocks of magnitude greater than 4 do not occur in the large slip area. Most large aftershocks take place near the edge of the large slip region and in the small slip region. Aftershocks also tend to cluster near the edge of the large slip region. These results are very consistent with numerical experiments of dynamic rupture, so it is suggested that the relation between aftershocks and coseismic slip pattern obtained in this paper hold generally for earthquake rupture processes. A clear delay of rupture propagation occurs in the large slip area during the 1969 GifuKen-Chubu earthquake: on the other hand, the small slip area in the 1980 Izu-Hanto-Toho-Oki earthquake is characterized by a deceleration of rupture propagation. The large slip area in the former case is interpreted as a barrier which resisted fracturing at first and was broken with a high stress drop. In the latter case, mechanical weakness due to volcanic structure located around the source region, seems to have affected the rupture process. A similar geological condition may have affected the rupture process of the 1978 Izu-Oshima-Kinkai earthquake which occurred about 10 km south of the 1980 Izu-Hanto-Toho-Oki earthquake.

The purpose of our study is to examine what is the determining factor of the amount of “okozukai” (an allowance) and how it influences elementary/ junior high school students’ consciousness and behavior. / As a result of our analyses, we got the following findings. First, parents who are concerned about their children's education are likely to reduce the amount of “okozukai”. Second, the amount of “okozukai” have effects on children's behavior but it depends on whether parents take interest in education of children. “Okozukai” as a family education strategy doesn't necessarily have an equal influence on every child.
