Abstract | At the early stage of this paper, Okayama prefecture was analyzed by the author focusing on the tendency of main sightseeing-areas based on the number of tourists for three decades (Ichiminami, 2002). In this study, the main sightseeing spots in Okayama pref. are also examined and the developments are explained in a more detailed and updated perspective by extending over current features and the number of tourists. One of the important reasons in a significant increase in tourists in Okayama is the opening of the highways, the bullet train and cross-linking of the Seto Ohashi Bridge. At the same time, there are some waves in the increase or decrease of the tourist trends appearing from several vital developments such as environmental, climatic, social, economic and spatial. In this regard, research objectives of the study are mainly based on investigating and making a comprehensive study on main sightseeing spots in Okayama pref. to find new tourism values and to provide a tourism inventory of Okayama pref. by means of information, data and clues from the field in/between the tourist destinations such as hotel guests, gardens and castles. Therefore, Okayama pref. has a rich potential of historical and cultural heritage in terms of spatial planning and growth. The important point is that the structural adaptation between historical and cultural assets and the city life should be provided and protected for domestic and foreign tourism as much as creating better futures in health tourism, gastronomy tourism, cultural tourism, belief tourism, congress tourism, thematic tourism and local tourism. |

Title Alternative | Changing Food Production based on Agricultural Enterprises in Tottori Prefecture |
FullText URL | fest_022_029_054.pdf |
Author | Ichiminami, Fumikazu| |
Abstract | The study aims to explain the main features of food production in Tottori prefecture focusing on agricultural enterprises. First, the number of farmers and farm households, the area of cultivated land, and their spatial distribution were analyzed. Then, the production trend on rice, livestock, vegetables such as watermelon and leek, and pears was surveyed. Furthermore, by overlooking the features of each enterprise, food production as a regional agriculture was briefly examined. Farm management in Tottori pref. has long been a small scale selfsufficiency property, but has gradually decayed or specialized. Because agricultural workers are continuously decreasing and aging, farming in Tottori pref. should pay attention to the demand of world food while publicizing a process on food production and farmmanagement carefully. |

Abstract | We have developed a minimum air temperature forecasting system using local meteorological observation data in order to prevent or mitigate the frost damage. In this paper, the correlation between the meteorological factors and the decrease in air temperature during the night was shown. Then minimum air temperature was predicted by the multiple regression equation that uses air temperature and humidity at 18:00 as explanatory variables. As the result, the root mean square error (RMSE) was 2.8°C. When the difference of air temperature between 17:00 and 18:00 was used for the prediction instead of humidity, the RMSE was 3.5°C. Next, the prediction was carried out only in clear nights, then the equation that use air temperature and humidity at 18:00 showed that the RMSE was 1.3°C. Although the predictive accuracy of the equations for clear nights is low on cloudy or rainy nights, we can forecast safely on frosty nights by using those equations in combination with the equations for all nights. |

Abstract | Statistical change in official temperature records at Okayama City caused by relocation of meteorological observation field of Meteorological Agency was evaluated. The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃. |

Abstract | A questionnaire survey by interview to the farmhouse in Nakhon Pathom Province in Thailand had been carried out, where the asparagus farming as the cash crop have spread rapidly. Valid response from 24 farmers were obtained and Asparagus had been planted in 30 plots within 74 plots (40.5%). As the result of statistical analysis on the geospatial preference for asparagus fields by logit model in which the geospatial characteristics of plots such as elevation, slope, curvature, acreage and distance from farmhouse were adapted as the explanatory variables while the category of the cultivated crops in there was adapted as the independent variable, it became clear that as for the asparagus plots, small lots were more preferred. On the other hand, the geospatial preference for asparagus plots such as elevation, slope, curvature and distance from farmhouse did not became clear. |

Title Alternative | Measurement of thermal conductivity in the soils of Shirakami Mountains |
FullText URL | 011_089_092.pdf |
Author | Hanzawa, Wakako| Moroizumi, Toshitsugu| Sasaki, Choichi| |
Abstract | Thermal conductivity of soils in Shirakami Mountains that was registered on UNESCO's World Natural Heritage in 1993 were measured using a twin transient-state cylindrical-probe method. The typical results were as follows:(1) Thermal conductivity of the soils in Shirakami Mountains increased according to an increase of soil water content, which was the same tendency as the other soils. (2) The thermal conductivity of the soils was about 0.2~0.3 Wm(-1)K(-1) smaller than volcanic ash soils, and it showed the same tendency as leaf mold. |

Abstract | There have been proposed so far many methods of statistical diagnostics in Cox regression for checking the goodness of the estimated model or checking the adequacy of the data. The former type contains the checking of the overall goodness of fit, the validity of the assumption of proportional hazards and the proper functional forms of the effects of covariates. While the latter type contains the checking whether there exist singly and/or jointly influential observations in the data set. In the present paper we study numerically the performances of various methods of diagnostics including our method of influence analysis for multiple-case diagnostics (Sung and Tanaka, 2003) by analyzing a real data set of lung cancer patients. |

Abstract | Studies on the existing non-symbiotic diazotrophic systems still are the most promising for better use of biological nitrogen fixation (BNF) in agriculture. The possibilities for the extension of nitrogen fixation to rice plants still speculative. The prospect of extension of N(2)-fixation to other plants was originally formulated to simulate the possibilities for the biological use of atmospheric nitrogen in order to overcome the ecological and economical problems of nitrogenous fertilizers. In view of this, the present study was conducted for the characterization and identification of N(2)-fixing bacterial strains at the maturity (110 days) stage in rhizosphere of rice (BR 10, Oryza sativa L.) grown in Brahmaputra Alluvium soil of Bangladesh. The soil is characterized as 'Inceptisol' order and 'Aquept' suborder. It was identified as 'Dhamrai series', had 'silt' texture, pH 6.0 and 6.8 C/N ratio. The present results of the microbial tests on the rice rhizosphere soil demonstrated that out of 401 isolates, only 94 were branded as nitrogen fixing organisms per gram of soil, which is about 23.4% of the total isolates. Based on the selection criteria, four individual strains were selected for identification. Biochemical tests were conducted for proper identification. They were identified as Closteridium spp., Klebsiella spp., Bacillus spp. and Azospirllum spp. |

Abstract | According ot previous studies, we may expect that slow oscillations can occur in dynamics of a parameterized family of systems in which a biochemical oscillator is coupled to a stationary systems. We introduce some numerical results that confirm our expectation. The results suggest that it is possible for slow oscillations to occur in dynamics of a system in which an active oscillatory unit is coupled to a passive medium, and that it is possible for circadian oscillations to arise from fast glycolytic oscillations in such a coupled system. |
Keywords | circadian rhythm glycolytic oscillation nonlinear oscillator |
