A simple test method using small sized specimens is often required for the effective development of ceramic materials. In the present work, the Modified Small Punch (MSP) test was employed for evaluating the thermal shock resistance of Y<SUB>2</SUB>O<SUB>3</SUB>-ZrO<SUB>2</SUB> and SiC ceramics.<BR>The change in strength after quenching from various temperatures was evaluated accurately by the MSP test. The load vs. deflection curves obtained by the MSP test provided more detailed information about the thermal shock by quenching. It has been found that the measured values of the critical temperature difference which indicates the thermal shock resistance of the ceramics are in good agreement with the theoretically calculated values for the materials investigated in the present work. The results show that the combination of water quenching and MSP test is effective for the evaluation of thermal shock resistance of ceramics.

明治の後半からの北海道の雪崩情報を新聞から収集した。過去95年間の雪崩災害件数は666件,死者は722人におよんだ。雪崩災害の内容をみると,北海道の開拓の歴史を反映している。明治時代は海岸部の民家の被害が,昭和に入ると鉄道や鉱山が,戦後は森林伐採やダム工事,道路が,さらに近年は登山やスキー関連の事故が目立っている。

We have a variety of the social problems like the poverty, the human right, environmental problems and so on, especially after 1990's. But they identify that the central government or the municipality at fiscal risk don't have the capability enough to respond to such social problems. Therefore, the enterprises which detect the solution of such social problems in their business recently emerge. We call them the social enterprise. We examine the movements and the development of the social enterprise in this article.

Natural disaster such as a drought or a heavy rain destroys environment of a farm village. On this account farmers poor economically increase and they throw away the cultivated land and come to run away from a farm village. Decrease of farming population becomes a big burden for daimyo finance. Quantity of agricultural production decreases, and the yield of taxes to the government decreases. The government carries out a policy to relieve a poor farmer. For example, the government provides it with food and money for relief for a farmer temporarily. However, a farmer is not satisfied with a relief system of the temporariness when the government performs it. The relief system that the government holds protects a rich farmer. However, a relief measure is insufficient for a very poor farmer. In other words this relief measure is unequal. On this account a phenomenon that a farmer runs away from a farm village is not finished. Because they think unless enough relief is taken. However, the government must stop such an economic vicious circle. The government takes new means. It is a policy to give new people the abandoned cultivated land. They did work looked down upon and lived a poor life. It is work considered to be vulgar processes the body, and to make Japanese sandals. The people who had been discriminated against got the cultivated land and got possible to earn a stable income. It was the thing that was epoch-making for their history that had own cultivated land. Because they did not have means of main production till now. This is the original policy that is not examined in daimyo territory nearby. However, the people continued discriminating against them even if some their life became rich. Rather I can point out that a discrirr}inatien pollcy was strengthened socially more in the latter half of the Edo era. Social discrimination is not broken off by the economic richness.
