Abstract The effects of ultrasonic surface treatment (UST) on the crystallization behavior and optical emission properties were investigated for the transparent glass-ceramics prepared from calcium aluminosilicate glasses co-doped with Eu(2+), Nd(3+). The glass-ceramics A were prepared by sintering a glass 45CaO・45Al(2)O(3)・10SiO(2) (mol%) containing 0.5Eu(2)O(3)+1Nd(2)O(3) under a 2% H(2)+98% Ar reducing atmosphere. In the glass-ceramics A, three crystalline phases, CaAl(2)O(4) (CA), CaAl(4)O(7) (CA2) and Ca(2)Al(2)SiO(7) (CAS) were commonly confirmed by X-ray diffraction. No drastic change in the amount of the precipitated crystalline phases was observed even in the case using UST of CA powders. It was suggested that the optical emission properties of the glass-ceramics A was responsible for the CA2 crystals. The glass-ceramics B were also prepared from a 51CaO・42Al(2)O(3)・7SiO(2) glass. The CA crystals were separately precipitated in the glass-ceramics B. In particular, a large amount of CA was successfully produced by stirring the UST suspension to prevent the sedimentation of the UST particles. The glass-ceramic B so-prepared showed strong photoluminescence but weak phosphorescence compared with other glass-ceramics B, indicating that the photoluminescence and phosphorescence were originated in different electron-trapping levels. The amount of the trap levels associated with the long lasting phosphorescence, such as oxygen vacancies, was probably small in the glass-ceramic B prepared with the stirring UST.

Abstract c-junはニワトリの癌ウイルスから分離された癌遺伝子(v-jun)のproto-oncogeneであり,その遺伝子産物は細胞内転写促進因子AP-1の主成分である。v-jun,c-junのトランスフォーム能を検討するために,我々はv-jun,ニワトリc-jun遺伝子さらにJUN遺伝子の種々の組換え体を複製能を持つレトロウイルスベクター(RCAS)に挿入し,CEF細胞(ニワトリ胎児線維芽細胞)にトランスフェクションした。その結果4か所存在する両者の構造的相違のうち,アミノ末端近くの27アミノ酸の欠損と3' untranslated regionの欠損が十分なトランスフォーム能と転写促進能発現に必須であることが明らかとなった。これらの部分がどのように機能発現に関与しているかは,これからの研究を待たねばならない。
Abstract Alternative V-jun is the oncogene which was isolated from the avian transforming virus ASV17. C-jun is the proto-oncogene of v-jun. The product of the proto-oncogene, c-jun, is a major component of the AP-1 transcription complex. AP-1 regulates the transcription of several genes through its ability to bind specifically to the sequence TGACTCA and variations of this motif. In order to assess the transforming capability of c-jun protein, we have introduced v-jun, the chicken c-jun proto-oncogene and several mutants into a replication competent avian retroviral expression vector (RCAS). Each of those was expressed in CEF and assayed for transformation by focus formation. Analysis of the results reveals that deletion of a region of 27 amino acids near the amino terminus of c-jun and deletion of 3' untranslated sequences are critical in activating the full oncogenic potential of jun.

Title Alternative Management of Rural Region in Association with Its Regionality of the Western Part of Tottori Prefecture
FullText URL 006_053_065.pdf
Author Ichiminami, Fumikazu|
Abstract In this paper the brief history, the status quo and the problem of regional management in association with its regionality were examined in Yodoe town and Mizokuchi town in the western part of Tottori Prefecture. These areas have the focus of Yonago city. Mt. Daisen and Kaike-spring have been well-known, and Tottori Flower Park recently attracts many tourists. However, agriculture also flourishes remarkably in these areas. Although Yodoe town has been celebrated for the waters and traditional umbrella, the town management recently makes the most of acorn and ancient tombs, giving emphasis to international relations and history. In Mizokuchi town the oldest legend of ogre has been investigated intently and the town management in connection with it has been proceeded. As these plannings use their histories and features peculiar to the area as a management concept, they have high originality. As a future problem, it may be necessary to built up a closer connection and coordinate each regional functions within the extensive areas.

Abstract In functional principal component analysis (PCA), we treat the data that consist of functions not of vectors (Ramsay and Silverman, 1997). It is an attractive methodology, because we often meet the cases where we wish to apply PCA to such data. But, to make this method widely useful, it is desirable to study advantages and disadvantages in actual applications. As alternatives to functional PCA, we may consider multivariate PCA applied to 1) original observation data, 2) sampled functional data with appropriate intervals, and 3) coefficients of basis function expansion. Theoretical and numerical comparison is made among ordinary functional PCA, penalized functional PCA and the above three multivariate PCA.

Author Li, Jinsong| Kawara, Osami| Ono, Yosiro|
Abstract The main problems caused by eutrophication result from the increase of phytoplankton. Therefore, controlling the increase of phytoplankton is the most important. In this study, we discuss the influence of current velocity on the growth of phytoplankton based on the field experiments and laboratory experiments. The laboratory experiments for the influence of current velocity on the growth have been conducted using circular channels, and the field experiments were conducted using a shallow pond. The results of the experiments show current velocity inhibits the growth of phytoplankton.

Abstract Relationship has been discussed by Tanaka and Zhang(1999) between the sensitivity analyses based on influence functions and on Cook's local influence, and it has been shown that equivalent results are obtained under general conditions by these analyses in statistical modeling without/with equality constraints. However, a condition implicitly assumed in the proof in Tanaka and Zhang(1999) in the case with equality constraints does not necessarily hold. The present paper gives a complete proof without assuming the condition. Also a formula for the normal curvature is derived for the convenience of practical computation.

Abstract Analysis of covariance selection models is a useful multivariate method to analyze the covariance structure of a multivariate normal distribution. It is used to reveal cause-and-effect relationships. In the present paper we review the theory and study numerically how the stepwise procedure of covariance selection works in actual data analysis. Then we try to develop a method of influence analysis in covariance selection, and show a numerical example to illustrate the usefulness of the method of influence analysis.

Abstract In many epidemiological and medical studies, a number of cancer motralities in catagorical classification may be considered as having Poisson distribution with person-years at risk depending upon time. The cancer mortalities have been evaluated by additive or multiplicative models with regard to background and excess risks based on several covariances such as sex, age at the time of bombings, time at exposure, or ionizing radiation, cigarette smoking habits, duration of smoking habits, etc. An interest herein to examine an additive, synergistic,or antagonistic relationship between radiation exposures and cigarette smoking habits for cancer mortalities. The results revealed a highly significant antagonistic influence for cancer mortalities from all nonhematologic findings, lung and respiratory system with negative interaction between radiation exposures and cigarette smoking amounts.

Abstract Many kinds of mite was caused by allergy and sick house syndrome, so it has become one of the social problems. Farnesyl acetone is one of the most potent anti-mite agent. However the vapor pressure of farnesyl acetone is high even at room temperature. This indicates the anti-mite effect has not been sustained even though the agent has strong anti-mite effect. In this study, we attempted to prepare polylactide microcapsule with farnesyl acetone for the purpose of sustainable dosage form of anti-mite agent. Microcapsule was prepared by solvent evaporation, which was a method of microencapsulation. The effects of preparation conditions on the enclosing efficiency, the release of microcapsule and anti-mite effect of microcapsule were investigated.

Abstract Polymeric microcapsules encapsulating iron phthalocyanine (Fe-Pc) and zinc phthalocyanine (Zn-Pc) were successfully prepared in this study. Absorption spectra of polymeric microcapsules encapsulating metal phthalocyanines were measured in visible light range. It was expected from the results that the polymeric microcapsules encapsulating metal phthalocyanines showed high photocatalytic activity upon irradiation with visible light such as sunlight. The catalytic and phtocatalytic activities of encapsulated Fe-Pc and Zn-Pc were investigated in the decomposition of methylene blue in water. The encapsulatedd Fe-Pc with H(2)O(2) exhibited a high catalytic activity. Methlene blue was efficiently decomposed by interaction of Fe-Pc with H(2)O(2).

Abstract Nanoporous TiO(2) were synthesized via hydrolysis of titanium tetraisopropoxide (TTIP) in HCl acidic conditions using sodium dodecylsulfate (SDS) as a templating agent. The order of the nanostructure of samples before calcination was improved with increasing the SDS/TTIP molar ratio. The calcined samples presented uniform mesopore structure with the average diameter of 4-5 nm and considerably large surface areas over 200m(2)/g, although the periodicity of the nanostructure was exceedingly reduced by the removal of the template. The prepared TiO(2) exhibited exceedingly higher activities on the catalytic oxidation of benzene compared to the commercial TiO(2), probably due to the difference of their pore suructures.

Abstract 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.

Abstract 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.

Abstract China has achieved a remarkable economic growth in the past two decades. However, the rapid economic development has led to regional disparities between the advanced coastal regions and the other regions. Regional development planning in China has sought to achieve the redress of regional disparities as well as a high economic growth. This paper aims to examine the role of core cities in the development of Chinese regional economy and their impact on regional differentials. Following a brief review of regional development planning in China, the paper examines the role of core cities on the regional development and the trends in regional disparities using data for seven coastal provinces (Guangdong, Fujian, Zhejiang, Jiangsu, Shandong, Hebei and Liaoning) and three municipalities (Beijing, Tianjin and Shanghai) in the period 1989-1997. It shows that while the coastal regions achieved a high economic growth, the extent of regional disparities and the contributions of core cities to the reduction of economic differentials varied among provinces. The paper concludes by proposing future issues on regional development planning in China.
