抄録	To explore the ceramic materials appropriate for the coatings with high mold releasability, molecular orbital (MO) calculations have been applied to the ceramics with NaCl structure, such as TiN, TiC, CrN, etc. Chemical bonding characters were evaluated based on the MO calculations, which were correlated to the experimental surface free energy. The dispersion and polar components of surface free energy indicated high correlation with the bond overlap population of the surface bonds and the net charge of inside atoms of the cluster models, respectively. Among the ceramic materials investigated, MoN had the lowest surface free energy, being expected to be most suitable as the ceramic coating material with high releasability

抄録	In this study, we examined the change of rice cultivation in consideration of the global warming. In Japan, rice which is suitable for subtropical zone is grown even in an environment of cool-temperate climate. Since the rice varieties that resist of cold weather have been developed, rice cultivation spread to north parts of the country gradually. Land productivity of rice has also improved markedly. As a result, northern Japan became the main producer of rice. Now, taking not only crop production but also the landscape formation and preservation of the natural environment into account, we should think about the rural society from different aspects.

抄録	For evaluating statistical models one of the most effective criteria is cross-validation. But it requires a large amount of computation. Various alternative schemes are considered to reduce its computation. Modified generalized information criterion is one of those alternative schemes. In this criterion an influence function is used to estimate the parameters of the models. By the numerical simulation we studied the effect of an influence function.　 Surveying data of the lake depth are used as the sample data. We estimate the shape of lake bottom as spline surface. The estimated parameters and the estimated depths obtained by two criteria are compared and the effect of an information function is analysed.

抄録	In Japan, the number of full-time farm households had continued to decrease since the latter half of 20th century. The number of part-time households has been also decreasing remarkably in the last twenty years. Cultivated acreage also aligned with these tendencies and it has decreased. As a result, the farmland which is not cultivated increased and it may also grow into a social problem. Therefore, the present condition and future view of Japanese agriculture was elaborately examined in the study by analyzing the transition of non-cultivated arable lands from a historical perspective.
