抄録 To acclimate under orthophosphate (Pi) starved environment, plant species and cultivars display an elegant myriad of Pi-adaptive and rescue responses via reprioritizing internal Pi use and maximizing external Pi acquisition by reprogramming metabolism and restructuring root system architecture.Exploitation of considerable genetic diversity both between and within crop species and harnessing of these genetic variations can lead us to develop smart plants with improved P-acquisition, growth and yield under P-deprivation. To elucidate the effect of P-stress on plant growth, and P-efficiency under Pstarvation, 14 diverse Brassica cultivars were grown hydroponically in a climatically controlled chamber using sufficient (200 and 400 μM) and stress (10 and 20 μM) P-levels using ammonium phosphate (NH4H2PO4) as a P source. Cultivars showed differential growth behaviour in terms of biomass accumulation (shoot and root dry matter partitioning), percent distribution of Pi-concentration ([P]) and P-contents in plant parts (roots and shoots), and P-efficiency ratio (% PER)(relative shoot growth) indicating considerable genetic diversity among the tested Brassica cultivars. PER and the proportional increases in shoot dry matter (SDM) accumulation (SDMmax/SDMmin) in response to the P levels assisted in categorizing the cultivars into efficient and inefficient utilizers of the absorbed P from an ambient environment. Cultivars were classified into efficient responsive (ER), efficient non-responsive (ENR), non-efficient responsive (NER) and non-efficient non-responsive (NENR) by plotting ordination plots between PER and SDMmax/SDMmin under P-stress environment. Differential PER values at stress P levels corresponds to high P levels suggest that P efficiency mechanisms can be different from one cultivar to another within a give plant species and cultivars exhibiting high PER values are better choice to thrive under P-starvation.

抄録 A simulation study was conducted to evaluate the effects of basic slag (BS10 and BS20: basic slag 10 and 20 t ha-1), aggregate size (A20 and A30: aggregate sizes of soil, less than 20 and 20-30 mm) and groundwater depth (Gw0: no influence of groundwater and Gw50: groundwater beneath 50 cm of the soil surface) as physico-chemical amendments in two pre-leached (leached for a week through tap water to remove excessive acidity and salinity from the soil before transplantation) acid sulfate soils of Badarkhali (Salidic Sulfaquept) and Cheringa (Typic Sulfic Halaquept) series in relation to the production of Chilli (Capsicum annum L.). Maximum growth and yield of chilli were recorded by the treatment combining A30Gw50BS20 in both the Cheringa (green chilli weight: 4.82 t ha-1) and Badarkhali (4.51 t ha-1) soils. The application of basic slag (BS20) was found to be the most effective among the individual treatments, followed by the BS10 > A30 > Gw50 treatments. The application of BS20 increased the yield in combination with the Gw0 treatment by 40% for A20, while by 107% for A30 in the Badarkhali soil. On the other hand, in the case of Gw50, these increments were 49 and 141% for A20 and A30, respectively. The application of BS at the highest rate (BS20) to the Cheringa soil was more effective compared with the A20 and A30 treatments in the Badarkhali soil. The same rate of BS20 in combination with the Gw50 treatment increased the yield by 59 to 147% in the Cheringa soil compared with 49 to 141% in the Badarkhali soil. Almost similar and significant (p≤0.05) effects were observed for the other growth parameters of chilli cultivated in both soil series.

抄録 The application of basic slag (BS20 and BS30: basic slag 20 and 30 t ha-1) and aggregate size (A20 and A30: aggregate sizes of soil less than 20 and 20-30 mm) and different techniques (Tech 1: pyrite at top, jarosite at middle, and top soil at the bottom of ridge; Tech 2: top soil at top, pyrite at middle, and jarosite layer at the bottom of ridge) exerted significant (p≤0.05) positive effects on the growth and yield of eggplants cultivated under field condition and the effects varied not only with the kinds and amounts of amending materials but also with the techniques applied. The soil showed a silty clay loam texture, initial pH value of 4.1, pyrite content of 55 g kg-1, base saturation of 47%, ECe value of 3.6 dS m-1, high exchangeable Fe3+ and Al3+ contents of 1.47 and 5.29 cmolc kg-1, respectively. The pH value of the average soil data obtained from all the treatments during fruit set (95 days after transplantation) of eggplants was found to be increased in pH by 1.2 units higher compared with the control (i.e. initial pH value). The contents of P, K, Ca and Mg in the average soil data during fruit set were found to be increased (IOC = increased over control) by 41 to 127% IOC, while the contents of Al3+, Fe3+, Na+, Cl- and SO4 2- in the soil were found to be decreased by 28 to 92% IOC. The different treatments on eggplants grown under the modified-plain-ridge-ditch techniques in the Cheringa acid sulfate soil significantly (0≤0.05) increased the fresh yield of eggplants, and the increment was more pronounced with Tech 2. The maximum yield of 17.8 t ha-1 of eggplant for Tech 1 and 20.1 t ha-1 for Tech 2 were recorded by the application of BS30 in the soils of smaller aggregates (A20) at the ridges of Tech 2, followed by the A30BS30 treatments in both the techniques. The lowest quantity of 1.7 t ha-1 yield was recorded by the control treatment. The eggplants grown in the ridges of both the techniques exhibited the best responses on N, P, K, Ca and Mg contents in eggplant tissues during fruit set. As expected, the lowest contents of these nutrients in the eggplants were recorded in the control treatment. Sulfur content of the eggplants grown in the control plots was 3.6 g kg-1 and was in the range of adequate S content (4 g kg-1). However, the S contents in the eggplants grown in different treatments were significantly (p≤0.01) lower compared with the adequate level. The effectiveness of the treatments for the reclamation of the soil in relation to the growth of eggplants was: Tech 2 > Tech 1, BS30 > BS20, and A20 > A30. The results suggest that the physicochemical properties of the soil, and the growth, yield and nutrition of eggplants were strikingly improved by the application of flash leaching followed by BS30 and A20 treatments in the ridges of Tech 2, and are regarded as the best reclamation measures for this acid sulfate soil.

著者 市南 文一|
抄録 In this paper, we aim to explain the history and areal distribution of grape production in Okayama prefecture with the special attention to the main kinds of grapes. Although Muscat cultivation in glasshouse was already been introduced in the 19th century, grape production had remarkably increased up to mid-20th century. After various kinds of grapes such as Neo-Muscat and Campbell Early have been cultivated, it has come to concentrate on the production of Pioniere in Okayama prefecture. The cultivated area of grapes is, however, decreasing gradually due to aging in the farm labor force and the lack of agricultural successors. In the light of the investigations, this research subsequently stated the outline and the transition of the grape production with the exsisting statistical materials etc.

抄録 An incubation study was conducted with the topsoils (depth: 0-20 cm) of two different series namely Cheringa (silty clay loam, pHwater 3.6, electrical conductivity = EC 18.5 dS m-1, CEC 17.2 c mol kg-1, organic matter = OM 39.1 g kg-1, and Badarkhali (silty clay loam, pHwater 3.9, EC 19.0 dS m-1, CEC 18.40 c mol kg-1, OM 30.7 g kg-1) acid sulfate soils to evaluate the effectiveness of basic slag (BS) for the neutralization of acidity and solubility of basic cations. These soils received BS at the rate of 0, 11, 22 and 33 t ha-1 under various moisture regimes (moisture at saturated condition, i.e. 100 % moisture, moisture at field condition, i.e. 50 % and wetting-drying cycles of those 50 and 100 % moisture levels). The impacts of these treatments on some selected properties and changes in water soluble bases in these soils were studied at different periods of 180 days of incubation. The application of BS was found to be increased the pH of soils from 3.6 to 5.1 for Cheringa; 3.9 to 5.2 for Badarkhali soils during the 180 days of incubation. These increments were more striking with the highest doses of BS at 33 t ha-1 under saturated moisture conditions in both the soils. The EC of the soils had not much influenced by the application of BS, regardless of time. The treatments were exerted significant (p≤0.05) effects on the solubility of basic cations in different periods of incubation. The maximum release of the bases were recorded during 180 days of incubation under saturated moisture condition and the findings will be supportive for planning of crop production on these soils.

抄録 Filters are essential in the design of embankments/dams, drains and wells for water and oil supplies. As a result of these functions, filter use is increasing. In order to use the required filter, various empirical relations have been given based on mathematical and field experience. However, these guidelines have not worked to perfection considering the fact that clogging within the filter face is a serious challenge. A short review on filter design criteria is given in this script coupled with a numerical formulation to propose the design limits.

抄録 Echelon analysis (Myers et al., 1997) is a method to investigate the phase-structure of spatial data systematically and objectively. This method is also useful to prospect the areas of interest in regional monitoring of a surface variable. The spatial scan statistic (Kulldorff, 1997) is a method of detection and inference for the zones of significantly high or low rates based on the likelihood ratio. These zones are called hotspots. The purpose of this paper is to detect the hotspot area for spatial data using echelon. We perform echelon analysis for Korea earthquake data. We use ESRI’s ArcGIS that is geographical information system (GIS) software to make the meshed areas and get contiguity information of these areas. With this contiguity information on the meshed areas, we detect the hotspot area using echelon analysis and spatial scan statistics. In addition, we compare with the result of analysis based on the total of number of times simply and the seismic wave energy.

抄録 The purpose of this study was to develop an instrument to measure the school administrators' assessment scale of teacher performance. First, organizational psychological research on performance appraisal and the factors that affect the rating was reviewed. Next, organizational research on the school administrators' assessment scale of teacher performance was reviewed. It was noted that performance appraisal must be accurate because it is used the decisions about promotion, salary, assignments, and education. After problems were described, a new version of the school administrators' assessment scale of teacher performance was developed. In the Study 1, an inventory of the principals' assessment scale of teacher performance was conducted by 98 primary school principals. Factor Analysisof scale of the principals' assessment resulted in 6 factors (Treatment of school business, Classroom management and Pupils' Guidance, Educational guidance, INterpersonal skills with children, School-based training of teachers, Educational guidance, Organizational activity). In the Study 2, an inventory of the assistant principals' assessment scale of teacher performance was conducted by 104 primary school assistant principals. Factor analysis of scales of the assistant principals' assessment resulted in 5 factors ( Interpersonal skills with children, Organizational activity, Classroom management and Pupils' Guidance, School-based training of teachers, Intersonal skills with parents and collegue). Results were discussed from multi-dimentional assessment scales of teacher performance including of contextual performance.

抄録 「権威」や「規律」の問題は、一方では子どもを上から外から強制し規制する、いわば反教育的なものとされ、他方、今日の教育問題は「規律」を育てられない親や教師の教育力の低下、親や教師の「権威」の失墜にあるとし、その回復を能力に見合った教育と究極における家族愛や国家愛の教育に求める。いま、教育における「権威」や「規律」の問題は、批判の対象であるとともに回復すべき事象ともなっている。本論文ではこの間題について、日本での実践・理論と重ね合わせつつ、ドイツを代表する教授学者の一人でもあるエブリの論考を手がかりに考察し、第一は、「権威」や「規律」という問題は、好むと好まざるとにかかわらず、教育実践において常に存在しているということ、第二は、教育的権威を四つの枠組みにおいて捉えること、第三に、個人の規律と集団の規律を相互関連的に捉えることの重要性について論究した。

タイトル(別表記) A Synchronic and Diachronic Analysis of the Word 'Creature' : With Special Reference to Richardson's Epistolary Novels
フルテキストURL 137_115_124.pdf
著者 脇本 恭子|
抄録 The present paper aims at examinig the word 'creature' from both synchronic and diachronic perspectives. The first section begins with providing several definitions of 'creature,' along with its etymology, in reference to such major dictionaries as the Oxford English Dictionary and Johnson's A Dictionary of the English Language(1755). In the subsequent three sections, the frequency and the collocation of this word are investigated through Richardson's Pamela and Clarissa as our main linguistic materials. A comparative discussion is made with several literary works from the late 16th to the early 19th centuries. Our final purpose here is to explore one of the stylistic features peculiar to 'sentimentalism' - a literary trend in eighteenth century English where Richardson played a significant role as its founder.

タイトル(別表記) The Process of a Search for Meaning in Middlemarch

著者 福永 信哲|
抄録 The present paper focuses attention on the process of a search for meaning conducted by Dorothea the major protagonist in George Eliot's Middlemarch during her days of the honeymoon in Rome. The process of her growing awareness of Casaubon her husband's pathetic reality is seen to represent her emergence from narcissistic idealism into a higher vision of seeing things as they are and sympathizing with fallible fellow beings. First it is made clear that Dorothea's self-idealized sense of devotion in regard to her subsequent husband Will Ladislaw the romantic voice of George Eliot's own. Then we place the process of Dorothea's self-discovery in the light of the author's own spiritual autobiography. Lastly we bring into focus a stylistic analysis of the discource depicting Dorothea's awakening. Thus we see how scientific imagination and the romantic vision of seeing into a whole organic unity behind the seeming miscellaneousness strike a subtle balance in the conception of Dorothea's drama.

抄録 The current state of English as a Lingua Franca (ELF) used in communication between nonnative speakers of English seems to require a change in the way English is taught and learned. However, English has still been taught and learned as a foreign language as ifit were mainly used in communication with its NSs. This article attempts to review some ofthe recent advances in ELF research and then to draw their pedagogical implications.

抄録 Although previous studies investigating physical performance and biomechanics in wheelchair-bound athletes were reported, few studies have characterized the psychological state of these athletes. This study investigated differences in psychological characteristics among 37 wheelchair-bound athletes (Japanese males, n=11; Japanese females, n=9; Korean males, n=17). All subjects belonged to their own national teams for disabled wheelchair basketball. All subjects completed both the Diagnostic Inventory of Psychological-Competitive Ability for Athletes (DIPCA) and the Profile Of Mood States (POMS). Statictics analysis of DIPCA showed that the psychological competitive abilities in the Japanese males were significantly better than those in the Korean males in this series. However. the scores on POMS did not show significant differences between the Japanese and Korean males, expect for the score for "anger". Neither DIPCA nor POMS showed any significant differences with regard to gender. Above all, we conclude that the psychological differences between Japanese and Koreans reflected the outcomes of international competitions and these there was no gender difference in psychological characteristics.

抄録 This note refers to recent problems of the technical terms used in the social sciences in Poland. The current system transformation process in Poland has a great influence upon the political, economic and social life. Many new technical terms are flowing into Poland with the progress of the radical transformation of the system. In part one, the author presents the general situation of the inflow of the words of foreign origin, the occurence of the new words and concepts in connection with the change of economic relations, the social life and the basic ideology of society. Part two is an introduction of new Polish basic dictionaries, other dictionaries of technical terms for social sciences, and the new texts of economics. The author also makes some comments on these dicitionaries and texts. This note is an attempt to make clear the main problems of current Polsh language for the editing work on "The Polish-Japanese-English Dictionary of Political Economic Terms".

抄録 This is a translation of the paper (mimeo) written by Mark Mazur, the economic adviser to the Deputy of the Minister of Finance in Poland. The subject of considerations in this paper is the development of the Polish banking system and its current problems. The banking sector in Poland is in the process of restructuring and development. State banks have been privatized and financially restructured. Many small banks have established. On the other side, banking sector has been affected by diffictlties asocciated with the period of transformation to a market economy. The author analizes the process and its problems from the viewpoints of credibility, quality, of service, competition, privatization and consolidation. The author indicates; decreasing trend of bad dubts, passive financing activities of banks to private sector and inclination to investment into the state bonds, regional and segmental monopolization of the main banks, and difficulties in the process of consolidation.
