| Abstract | The purpose of this study is to build a forecast system for predicting at minimum air temperature in the next morning from the meteorological data, such as air temperature, humidity, and the amount of solar radiation, in a field in the evening on the previous day. The meteorological data are sent to a relay server, and then, transferred to a PC in our laboratory of Okayama University by executing the computer program to import the data which are used to calculate the predicted values of minimum air temperature. The predicted minimum air temperatures are released for the farmers on the website in the server of Okayama University. The website is also created by our laboratory. As a result, the predicted minimum air temperatures agreed with the measured ones. |

| Title Alternative | Production and Shipment of Eggplant in Okayama Prefecture Focusing on the Eggplant Cultivation in Greenhouse in the 7th Division of the Kojima Bay Reclaimed Land |

| Abstract | The main purpose of this study is to explain the production and shipment of eggplant and the management of farm households in the 7th division of the Kojima bay reclaimed land in Okayama prefecture. 10 pioneers began to cultivate eggplant in a greenhouse in 1969 and the number of farm households, acreage and shipment increased dramatically until the early 1980s. However, decline or stagnation trend has continued thereafter. Farm workers are often 50 years old or more, each farmer has cultivated eggplant, rice, two-rowed malting barley in family management by 2 or 3 persons. Work begins in July. Eggplant seedlings are planted in August, harvest begins in October and heating in November. Pest control is necessary throughout the year, but pesticide use has decreased in recent years. In order to suppress the occur -rence of the pests, workers use both the bunker crops like sesame and natural enemies like Amblyseius swirskii . However, because the prices of agricultural materials and fuel are recently soaring, the farm management of eggplant has become increasingly severe. We propose to expand the sales network by advertising and a more aggressive acceptance of new farmers. |

| Abstract | This study investigated the civil consciousness on the preserved trees in Himeji city, Hyogo prefecture. We conducted data collection in the city hall,,observed preserved trees, and examined the awareness of citizens against the preserved trees in the central area and Syosya-zan Engyo-ji. As a result, it was revealed that the citizens are not indifferent to the natural environment of trees, etc., they also do not have a strong interest in it in particular. As for preserved tree system, there were some slight differences in the recog -nition between the people who actually take care of trees and administration. People are in favor of the need for the current system of preserved trees. However, in Japan, which is blessed with many things, people do not recognize strongly appreciating the natural environment. |

| Title Alternative | Material design for the ceramics coating with high mold releasability by using molecular orbital calculations |
| FullText URL | fest_019_022_025.pdf |
| Author | Nanba, Tokuro| Fujihara, Jiro| Sakida, Shinichi| Benino, Yasuhiko| |
| Abstract | 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 |

| Abstract | 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. |

| Title Alternative | Numerical Evaluation of the Approximation by an Influence Function |
| FullText URL | fest_019_001_007.pdf |
| Author | Bao, Hong Mei| Fueda, Kaoru| |
| Abstract | 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. |
