| 抄録 | Morphology and formation mechanism of poly (4'-oxy-4-biphenylcarbonyl) (POBP) crystals obtained by solution polymerization were firstly treated. It was concluded that the formation mechanism of the bundlelike aggregates of fibrillar crystals in POBP was fundamentally simillar to that in POB whiskers. Secondly the copolymerization effects of m-acetoxybenzoic acid and 4-(4-acetoxyphenyl) benzoic acid on the morphology of POB whiskers were studied. The experimental results strongly supported our proposal for the formation mechanism of whiskers which was consisted of crystallization of oligomers with a critical length as lamellae from solution and solid state polymerizationof oligomers between lamellae. Finally, the formation mechanism of poly (p-oxycinnamoyl) spherical products during solution polymerization was treated. The formation of these spherical products could be understood by overlapped phase diagram of melting depression curve and consolute curve of oligomers-solvent system. |

| 抄録 | An alumina-zirconia (AZ) composite powder was prepared by thermal decomposition of the organic precursors, which were synthesized from ethyl acetoacetate aluminium diisopropylate and zirconium n-butoxide. Specific surface area of AZ was higher than that of alumina-zirconia (ALK) prepared from aluminium sec-butoxide and zirconium nbutoxide. True density of AZ was lower than that of ALK. Selective reduction of nitrogen oxide with propylene in oxygen-rich atmosphere on AZ was superior to that on ALK. |

| タイトル（別表記） | Secular changes of air temperature and precipitation in Okayama City. |
| フルテキストURL | 001_163_168.pdf |
| 著者 | 三浦 健志| |
| 抄録 | In this paper, secular changes of air temperature and the amount of precipitation in Okayama city are discussed using observed values at Okayama meteorologiccal station. Special reference is made to 1993 and 1994 in which peculiar changes occurred. The results obtained are summarized as follows: (1) The increasing rate of the annual mean air temperature at Okayama city is 0.85℃/100y. This value is nearly equal to the average of Japan; 0.87℃/100y. (2) The increasing rate indicates seasonal changes, and the rate is high especially in April and May. (3) The rapid increase of the air temperature in the 1980s is due to removal of Okayama meteorological station from the edge of town to the center. (4) The annual mean air temperature in 1994 is 16.9℃, and the monthly mean temperature for July and August are 29.8 and 29.6℃ respectively. These values are new records at the Okayama station. (5) The air temperature in July and August, 1993 are higher than in 1980 when it was much colder in the summer. (6) The amount of precipitation does not show any secular changes. |

| 抄録 | Encapsulation of thiophen and bithiophen in two kinds of hexagonal faujasites (Na-EMT and H-EMT) with various concentration of Cu(2+) ions have been investigated and characterized by means of themoanalytic and spectroscopic methods. From the results, it was found that the progress of polymerization of thiophen and bithiophen in the lattice space depended on Cu(2+) contents, and the encapsulation of thiophen in Na-EMT and H-EMT with Cu(2+) ions yielded polythiophen clusters with electron states of bipolaron. On the other hand, polythiophen clusters synthesized by the encapsulation of bithiophen in H-EMT were found to be mostly polaron states. |

| 抄録 | Corrosion behavior of silica glass was investigated in high-pressure water vapor and water at 300℃. A linear weight loss in water vapor and a parabolic weight loss in water were observed. The weight loss for the former was larger than that for the later. The fracture strength of the corroded silica glass increased with the content of molecular water in the glass. The strength reduction was observed for the corroded silica glass after dehydration at 400℃ for 1 day. |

| 抄録 | Zinc oxide films were prepared on silica glass substrates by the use of an r.f. activated reactive evaporation (ARE) method, and were examined by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrical conductivity of the films and the doping effect of Al ions were also investigated. XRD measurements indicate that the films were c-axis oriented and that an r.f. plasma of Zn and O was necessary for the ZnO film deposition. Substrate temperature, oxygen gas pressure, evaporation rate, r.f. power and Al doping amount affect the c-axis orientation, the growth rate, the microstructure of the films and electrical conductivity. Optimum conditions with a fine texture of the surface and having good ctystallinity as well as good conductivity (≒10(-4)Ω・cm) were as follows : the substrate temperature; 200℃, the total evaporation rate; 1.0Å/s, the oxygen pressure; 2.0×10(-4) Torr, the r.f. power; 250W and the Al evaporation rare ratio; 2～6%. The films with 1.0×10(-3)Ω・cm were prepared at 50℃ for the substrate temperature. |

| 著者 | 西村 伸一| 清水 英良| 藤井 弘章| 島田 清| |
| 抄録 | A calculation method of probability of liquefaction is proposed in this paper. The spatial variability of soil parameters for the dynamic shear strength, i.e., N-values, median grain size, fines contents, and the statistical characteristics of the earthquake frequency are considered in the analysis. The standard penetration test (SPT) is convenient to estimate the spatial variability of the dynamic shear strength and mainly used in this study. Furthermore the determination of dynamic shear strength based on Swedish weight Sounding test also introduced here, because it is the simpler test than SPT. While the statistical model of the earthquake frequency is determined based on the record of historical earthquakes. Using this method the probability of liquefaction is calculated. The sand compaction pile method is considered for the ground improvement against the liquefaction. Finally, the relationship between the sand replacement rate and the probability of liquefaction is clarified. |

| 抄録 | In this paper, first it is investigated illegally parked bicycles around the Okayama station, withdrawal, storage and return of them. Second, there will be a questionnaire to understand citizen's consciousness and clarify how they have been grasped present condition. Furthermore, it is aimed that considering how to carry out an efficient activity for reducing number of illegally parked bicycles. The results are concluded as follows. It is much more required to strengthening in the criminal prohibition zone by applying withdrawal activities and regulations. Presumably, first it is required to change storage area in order to increase the rate of returned bicycles. Besides, it will be great improvement in rate of return, if definite proportion of area is confidentially secured on storage area near the Okayama station. Moreover, it was remarkable that a citizen was not known in detail about an illegally parked bicycle. On the other side, recognition of most of the suburbanite of Okayama-shi tends to be impervious and replied to affirm illegally parked bicycle. However, the residents who live an area near to station understood the present condition well, and they disapprove to the illegally parked bicycle. Finally, in order to improve present condition, to prevent completely and to decrease the number of illegally parked bicycles publicity work is required. |

| 抄録 | In this paper, the nature of Tsuyama region was explained in terms of several changing features such as agricultural, industrial, commercial, and sight-seeing activities. Also, short history of mining sulfide ore at Yanahara Town was described and the population change of surrounding area was analyzed. Although the vitality of agriculture in general has gradually fallen mainly due to the decrease of number of farm household, of the rate of full-time farm household, of the area of farmland, and of the harvested area of rice, tobacco, and Japanese radish, the production of black syobean and the rate of vegetables, etc. have increased. After the highway of Chugoku line was opened to traffic, the number of industrial parks and establishments suddenly increased in and around Tsuyama City and they employed many workers. Within the industries of Tsuyama City, manufactures of genaral and electrical machineries, equipment and supplies developed, but the ones of textile mill products, apparel and other finished products made from fabrics and similar materials declined. In sight-seeing, tourists of Yunogou spa have increased in a satisfactory. Population of the municipalities except Tsuyama City have decreased since 1970 and a number of large-sized stores have come to be located in the suburbs of Tsuyama City. |

| 抄録 | The aim of the study is to explain the present condition of the rows-of-houses preservation policy of Okayama Prefecture and to examine the samples in Maniwa city, Katsuyama area. Besides, the interview investigation was mainly conducted for residents in the rows-of-houses of preservation area in Katsuyama for giving the concluding remarks about the findings. The traditional private houses in Katsuyama preservation area were partially restored in the 1985-89 and 1993-97 fiscal years by the subsidy from the prefecture. Furthermore, Katsuyamacho at that time founded the subsidy system for maintaining rows-of-houses preservation area (about 25.3 ha) independently in 1993, restored 9 private houses, and made and updated the shop curtains; "Noren". In the point of the observable items, the ground warehouse of structures with gable tile-roofing is visible and it is also in use. Moreover, a latticed window structure, a white wall, and a sea cucumber wall constitute the charm of new rows-of-houses. A stone pavement follows on the riverside at the site facing the Asahi River. There are the remains of an arrival-and-departure place of a flat boat and a brewery, etc. According to our investigation in 2002, the residents were satisfied with "It is easy to live quietly", "the beauty of a natural landscape", "harmony of rows-of-houses and a shop curtain", and "a historical atmosphere", but the recognition of "the creation of active rows-of-houses" was unexpectedly low. Therefore, cooperation between residents and informational sharing are much more required. Consequently, since both the visitors and the residents are satisfied very much with each facilities, such as the whole rows-of-houses, a samurai residence, a brewery, and a restaurant etc., town planning is well organized and attained the priority targets. |

| 抄録 | The agricultural water has manifold functions for farming at community level. However, along with the difficulties to maintain the agriculture water path that are caused by the decreasing of farmers and the aging of the society, the agricultural water is losing its functions even that as water resource for local community. This paper presents a survey of the residential awareness on regional water utilization to find the possibility for the maintenance of agricultural water path. Economic evaluation is tried for the regional warter utilization function. This study is carried out at a regional level that covers both farming households and non farmers. Following three points can be confirmed based on the results of questionnaire survey. Firstly, local citizens admit that the agricultural water does have some values (3,037 Yen per household per year). Secondly, the higher the environmental awareness is, and the longer the citizen has lived there, the higher evaluation to function of the agricultural water can be observed. Thirdly, even within those who is holding high evaluation to the agricultural water, it is thought to be quite difficult to maintain the agricultural water path due to the aging of the society and uneven distribution of the participants. |

| 抄録 | Experience of flux measurements over tall canopies has revealed that the eddy flux of sensible plus latent heat is about 30% smaller than the available radiant energy flux. A systematic observation was carried out to investigate the imbalance problem on rice field. The rice field represents a complex system consisting of rice plant, irrigated water and soil. Date obtained in this experiment show that appreciable understimations of sensible and latent heat fluxes are not recognized but understimations of 15 to 23% are counted in the soil heat flux. |
