タイトル(別表記) | Process of Acid Sulfate Soil Formation from the Viewpoint of Moisture Conditions on Coastal Muddy Soil and a trial of it's Amelioration |

著者 | 足立 忠司| |
抄録 | According to recent soil survey data, it has been reported that acid sulfate soils cover areas of about 11,670,000 hectares all over the world and about 40% of those are in South-East Asia. Most of crops could not be grown on those areas without any amelioration due to low soil pH. This report consists of two parts. One is on acid sulfate soil formation in laboratory experiment. Another is on a trial of acid sulfate soil amelioration in field experiment. The results obtained on acid sulfate soil formation, in order to make clear the relationships between the process of oxidation of sulfur compounds and the moisture conditions (moisture suction) in coastal muddy soils, in laboratory experiment are summarized as follows; The concentration of sulfuric ions increase as oxidation of sulfur compounds contained in pyrite, etc. occurs, and as a consequence, the soil pH decreases in the coastal muddy soil (Fig.1). Especially, the soil pH decreased remarkably in the range of pF 2.3~3.4. The activity of soil microorganism takes part in this reaction by helping out with bringing about sulfur oxidation and formation of sulfuric ions. The pH decrease in the soil with autoclaved treatment was only slight at pF values lower than pF 3.0. Accordingly, it is concluded that the decrease of pH in coastal muddy soil occurred mainly due to soil microorganisms which oxidize sulfur compounds under the condition of higher-water than pF 3.0. The results of field experiment is summarized as follows; As a general rule, it is able to remedy the surface acidification of peat/acid sulfate soils by mixing lime dust with plough layer. However, the effect of mixed lime dust is easily disappeared in the area where the acidic ground water table is always high and moves up over the surface in rainy season. Therefore, it was carried out that several experiments for seeking protection against surface acidification due to capillary upward movement of acidic ground water by means of inserting a buffering layer of lime gravel (thickness of lime gravel layer =5㎝) between the top soil and the acidic subsoil (20 ㎝ depth) in the fields, Munoh series which is young acid sulfate soil, at the Narathiwat Land Development Center in South Thailand. The results of soil pH measurement carried out in the field in November of 1985, August of 1987 and September of 1990, it coincides with 2,4 and 7 years respectively after the beginning of the experiments, are shown in Table 3. In the plot of P2 and U1, application of lime dust to the plough layer can increase soil pH rapidly but it's residual effect is not so long. Within a 5 year period, the soil pH is likely to return to below 4. On the other hand, an underlaid lime gravel layer tends to improve the soil around the lime gravel only slight but steadily with time. Therefore, it is concluded that surface soil acidification caused by the upward movement of acidified ground water would be protected against, rapidly and continuously, by both mixing lime dust with plough layer and underlying lime gravel below plough layer. If acid sulfate soil areas would be used as upland fields, much of organic matters in soil are easily decomposed by drying. Therefore, it is suggested that it would be better for these areas to be used as paddy fields, also from the above results. |

タイトル(別表記) | Rain-water Retention of a Small-scale Upland Field in a Rainy Year and a Droughty Year |
フルテキストURL | 001_143_149.pdf |
著者 | 四方田 穆| |
抄録 | From the standpoint of water resources development and environmental preservation, rain water retentivity of agricultural and forest lands are evaluated. Measurement of rainfall and runoff has been carried out at the reclaimed upland field of 4.55 ha since 1981. In this article, water retention characteristics of this study basin is compared in a rainy year of 1993 and a droughty year of 1994. In cases of rainfall less than 20mm, most of the rain water infiltrates into the soil layer. On the other hand, about 75% of a heavy rain, such as 300 mm in 1993, runs off the soil surface. Within the infiltrating rain water, the ratio of water which is kept by capillary action and can be used by crops is estimated to be less than 40% in months of rainfall more than 150 mm, but in months of rainfall less than 50 mm, it is estimated that more than 80% of rainfall can be used by crops. The ratio of monthly rainfall which contributes to base flow recharge is 0 to 12% regardless of rainfall amount. |

タイトル(別表記) | Vonnegut's Brain Computer Laying stress on Galápagos and Hocus Pocus |
フルテキストURL | 002_145_161.pdf |
著者 | 諸川 重剛| |
抄録 | As Kurt Vonnegut (1922--) has written his novels to give warnings about the growing danger of society, in the case of valuation, it is very important to understand what happened in his time and how his works resulted from a historic background. In the late of 1970's and 80's, society underwent a few big changes, for example, signs of communism collapse on a line of the Soviet Union's perestoroika, Japanese rapid economic growth, the unbalanced world economy by the heavy fall in stock prices in America and, in the field of science, the progress of computer technology in the use of a semiconductor instead of a vacuum tube. The mentioned above data were input into Vonnegut's Brain Computer. As a result, Galápagos was publishied in 1985, Hocus Pocus in 1990. In this paper, I analyzes Vonnegut's works from such a point of view, laying stress on Galápagos and Hocus Pocus. |

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. |

著者 | 藤原 貴| 藤井 達生| 難波 徳郎| 高田 潤| 三浦 嘉也| |
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. |

抄録 | Our visual actions take both the sensory and reversible views in the relationship of the mutual coordination between them. And the visual actions, as a whole, realize the sensory scene when having the marked tendency to sensory views, and the reversible scene to reversible views. The author of Sakuteiki classified natural scenery into the landscape types called yo. The landscape types were transformed into the places where humans and nature happened to meet harmoniously. It was the main theme of the author of Sakuteiki to discuss how we should compose rocks in the place. We can find, in Sakuteiki, two manners of looking at nature, such as 'changing the taste' corresponding to the sensory view, and 'in compliance with the requesting mood of 'to the reversible view. They were, in the paper, studied to analyze the naturalistic landscaping of Sakuteiki. |

抄録 | Monodispersed porous polymer microspheres having diameter of ca. 50 μm were successfully prepared by suspension polymerization of styrene, polyoxyethylene methacrylate and ethylenegycol dimethacrylate. Monodispersed O/W emulsion was firstly made by SPG membrane emulsification technique, following droplets-swelling method of monodispersed seed emulsion by the addition of secondary emulsion. The effect of solvent used in suspension polymerization on porous structure of prepared polymer microspheres was investigated in this paper by identification with scanning electron microscopy, porosimeter and the performance in gel permeation chromatography. It was found that benzene, 1-butanol and butyl acetate worked as poor solvent for polymer prepared in this study and that polymer microspheres prepared with these solvents had larger pores. Gel permeation chromatography measurements indicates that polystyrene having molecular weight smaller than 50,000-100,000 can be clearly separated by using gel columns packed with polymer microspheres prepared with poor solvents. |

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. |

First, the distributions of population data in both years were drawn, then the population changes and the rates were explained. While large increaces and high growth rates were scattered in the suburbs of the city, large depopulation and high decreace rates were clustered in the old core in the built-up areas and rural areas in the hilly and mountainous areas. Second, the rates of population under 15 years old and the rates of population over 65 years old were analyzed. Finally, the age structure of population was examined with 10 samples of the quarters or sub-areas in anticipation. |
