昭和35年7月における道東農民の食糧構成ならびに熱量,蛋白質の摂取状況を階層別に比較考察した。その結果を総括すると1.全般的に,米以外の穀類および牛乳の消費量が多く,米および肉,果実が著しく少ない。2.カロリー摂取は1人1日平均2,135cal.であり,この89.8%は植物性食品から得ている。D階層のカロリー摂取は1,805cal.で著しく低い。3.蛋白質は1人1日平均77.Og摂取しており,そのうち24.5g(31.5%)は動物性蛋白質である。動物性蛋白質の摂取量は低階層にゆくほど低くなり,特にD階層は少ない。

Although heat conduction with phase change has a great field to be solved for its application not only to the study of various natural phenomena, but also to the practices, it seems that the study has not yet been sufficiently developed for the above mentioned purposes because of its difficulties. The authors, therefore, have tried to get a broad outlook in this field from a stand-point of dimensional analysis. Using dimensionless quantities derived from such an analysis, the partial differential equations of heat conduction can be changed to ordinary ones and it is shown that the general solutions obtained in this way include the exact solutions which have been solved likely by chance. Considerations of a dimensionless quantity being a ratio between the effect of latent and sensible heat, give an approximate and very convenient method to obtain a solution sufficiently exact when the value of the above-mentioned dimensionless quantity is large. This report also gives a rule to decide whether the moving velocity of an interface obtained in this way is higher or lower than that which would be given by the exact solution. The numerical analysis following E. Schmidt is also discussed briefly.
