I have investigated lifestyles, behavior patterns, causative factors, and progression of hearing loss in many patients with Meniere's disease, and found that lack of recompense for pressure of business, patience or service is responsible for the onset or progression of the disease. Further, aerobic exercise proved very effective to stop vertigo and improve fixed hearing loss. Three years ago, I advocated a new therapy for Meniere's disease consisting of aerobic exercise and countermeasures to remove the harmful factors in daily life (aiming at good sleep, omission, and relaxation). Because the new therapy has been far more effective than any conventional therapies, we must renew the treatment concept of and therapeutic strategy for Meniere's disease. I suspect the possibility that the CNS emotional center, stimulated by lack of recompense against stress in activities of daily living, influences the hypothalamus, which in turn reduces blood flow to the inner ear, and produces endolymphatic hydrops. Aerobic exercise, together with correction of irregular or inactive lifestyles, removes unhealthy factors, improves the subject's general physical condition, and finally cures endolymphatic hydrops.

近年、音声認識・音声合成を利用したエージェントベースの音声対話システムの研究が多くみられるようになってきた。エージェントに様々な表情を持たせることで新しいヒューマンインターフェイスを提供している。しかし、エージェントに様々な表現力を持たせる反面、それらの人間に与える影響が考慮されていない。そこで、本研究では人間とコンピュータ内のエージェントが互いに音声を用いてやりとりする上で、エージェントからの情報提示の変化による人間側の発話に与える影響を調査するために、Wizard of Oz(以下WOZ)方式による模擬音声対話システムを構築し、その実験の結果について考察を加えることとする。

人の発声する母音は, 一般にピッチと呼ばれるほぼ同じ形状をした単位波が繰り返される基本構造を持つが, 繰り返されるピッチ毎にその周期間隔および波形は微妙に"揺らぐ"ことが知らされている.この母音に含まれるピッチの"揺らぎ"は, 母音が人間的で自然な発声音として知覚されるために必要不可欠であることが分かってきた。現在の主流な音声合成法の一つである線形予測符号化法でも, 人間的性質持った母音を合成するために, 自然なピッチ揺らぎを再現することはきわめて重要である。そこで本論文では、「線形予測符号化法の枠組で自然な音声を合成するために重要な要素は何か?」について比較検討を行なう。

本研究は,知覚実験にもとづき「同化現象は知覚上許容される調音上の簡略化である」という仮説の妥当性を検討するものである。また,Steriade(2001)が提案した「P-map仮説」,つまり人間の知覚能力が母語や母語の音韻構造にかかわりなく同一であるという仮説も検討する。鼻音と側音の連続に関して異なる音韻パターンを示す3つの言語-朝鮮語,モロッコアラビア語,スウェーデン語-の話者を被験者として知覚実験を行なった結果,部分的ながら「P-map仮説」の妥当性が証明された。また同じ知覚実験から/ml/,/ŋl/という鼻音-側音の連続に見られる/l/の鼻音化が普遍的知覚原理に支配されており,n/lの連続に見られる/n/の側音化と/l/の鼻音化がともに知覚的に許容される変化であるという結果も得られた。

Rolling motion is one cause of mechanical sound. Rolling sound may cause serious problems when it is excessive in machines and structures, for example. A series of studies have been carried out in order to obtain basic information for the reduction of rolling sound. This third report concerns the generation mechanism of the sound. Horizontal square steel plates with different surface finishes were simply supported at four points. Nylon and steel balls with different surface finishes were rolled at various rolling velocities on the plates, and the sound was measured using a condenser microphone. Surface topographies of the balls and plates were also measured by a device measuring the deviation from circular form and surface roughness, respectively. The signals obtained in the measurements were analyzed by an FFT analyzer. From the experiments, analysis and considerations, the generation mechanism of the sound was clarified.

A single subcutaneous injection of a preparation of heat-killed Lactobacillus casei (LC 9018), given before or after irradiation, significantly increased the survival rate of mice that had received 8.5-Gy 137Cs whole-body γ-irradiation. A similar radioprotective effect was observed when LC 9018 was administered within the period from 2 days before irradiation to 9 h after irradiation, the pre-irradiation treatment being slightly better than the post-irradiation treatment. Increases in the weight of the spleen and in the number of endogenous spleen colonies on days 8 and 12 after irradiation suggested that the radioprotective effect was based on enhanced recovery of hematopoietic tissues. The activity of macrophage colony-stimulating factor (M-CSF) in serum was rapidly increased by the treatment and was maintained at the elevated level for 13 days. At the same time, an increased level of M-CSF mRNA was detected in the livers of the treated mice. However, LC 9018 failed to save the lives of mice when administered 3 days after irradiation, although it increased serum M-CSF as effectively as noted above. The small advantage of the pre-irradiation over the post-irradiation treatment was not explained by the increases of metallothionein in the hematopoietic tissues of the treated mice.

Business administration has made rapid progress as the practical science. It tends to discuss mainly with managerial phenomenon of growing companies, markets and industries. But it tends not to discuss with managerial phenomenon of maturing or declining markets and industries as if they lack appeal for study. It is a long time since Japan reaches the mature society and economy. In such situation, we suppose that we need to investigate managerial phenomenon of not only growing but also maturing or declining markets and industries. By investigations of managerial phenomenon of maturing or declining markets and industries, we should find the key for avoiding decline firms which drive for long-range survival and growth, and getting rid of stagnation. This paper focuses on "the phenomenon of Market Revitalization", which transform regrowth stage from maturity or decline stage of market evolution. Based on previous researches, we search some germs of new paradigm for anatomizing the mechanism of market revitalization. We advocate "The theory of Market Revitalization", which get down to understanding the interaction with firms and market in which firms enter. The new paradigm is presumed on the logic of environmental determinism, which changes of market environment determine firm's strategy and action. But this logic doesn't dominate the new paradigm. The new paradigm emphasizes on the logic of environmental determinism and environmental formation. The logic of environmental formation focuses the aspect that firm's strategy and action form market environment toward evolution. The theory of Market Revitalization focuses on the interaction with firms and market in which firms enter. And it aims for coevolution them. It suggests great ripple effects by new directions of innovation and innovation's intensification through interlocking of actions which entering firms compete or cooperate in market.

Average horizontal crustal strain rates during interseismic period in the Japanese Islands, except the Hokkaido district, are deduced from precise geodetic survey, which has been conducted since the Meiji era. First, distance change rates between the first order triangulation stations are calculated using the weighted least squares method. In regions which suffered from disastrous earthquakes or volcanic eruptions, data before the events are neglected in the above calculation. Second, strain rates in arbitrary triangular regions are estimated.The estimated strain rates ate less than 6×10-7/yr, which is greater than those derived from seismic moment release rate or displacements of active faults. The Japanese Islands may be divided into several provinces on the basis of disstribution of strain rates. In the Tohoku district, a N-S to NE-SW extension is prevailing, and there is a zone of small strain rates which runs parallel to the Oga-Ojika tectonic line proposed by MOGI (1985). This zone may be a boundary between crustal blocks. In the northern Kanto district, strain rates are very small, while a NW-SE compression is predominant in the southern Kanto district. These facts indicate that compressional forces due to the subduction of the Philippine Sea plate may not be transmitted to the northern Kanto district. There is a zone of large compression which runs from Niigata to Gifu through Matsushiro. These high strain rates show a good correlation with seismic activity in the crust. Although compressional strain rates are prevailing in both the Chubu and the Kinki-Chugoku districts, principal axes abruptly change their directions from NW-SE to E-W at around lake Biwa. The westernmost Chugoku and the northern Kyushu districts are characterized by small extension, which suggests that compressional stress predominant in the Chubu and the Kinki districts may fade out. In the Shikoku district, NW-SE compressional strain rates are prevailing. However, temporal variations in baseline lengths show that the elastic rebound associated with the 1946 Nankaido earthquake did not occur in the western part of shikoku. It is considered that the coupling between the subducting Philippone Sea and the overriding Eurasia plates may vary significantly from east to west. Large N-S trending extensions appear in the central Kyushu district, which is consistent with the spreading of the Beppu-Shimabara graben.

This paper focuses on "the phenomenon of Market Revitalization", which transform re-growth stage from maturity or decline stage of market evolution. We review some previous researches and construct the perspective of market revitalization. There are some revitalizing factors, which account for market revitalization. Previous researches discuss about secrets of vertical interaction between entering firms and customers in market. Before this interaction, firm's view about market environment contributes to market revitalization. But they don't definitely discuss about mechanism of horizontal interaction among entering firms in market. This interaction centers on competition and cooperation among firms. Assuming that certain firm's action is trigger factor for market revitalization, there are great ripple effects by new directions of innovation and innovation's intensification through interlocking of actions which entering firms compete or cooperate in market. We try to organize four Market Revitalizing Strategies. Market Revitalizing Strategies are compounded vertical interaction between entering firms and customers in market. Next, we try to organize four patterns of horizontal interaction among entering firms in market. Finally we try to construct the perspective of market revitalization by taking vertical and horizontal interaction into consideration.

This paper focuses on "the phenomenon of Market Revitalization", which transforms from maturity or decline in the process of market evolution into a stage of regrowth. We review some previous research about market revitalization and look for clues about constructing perspectives on market revitalization. There are some revitalizing factors, which account for market revitalization. Revitalizing factors consist of external factors which firms can't control directly, and working factors which firms can work on entering market independently. Previous research discusses the secrets of vertical interaction between the firm's entry and its customers in market. Before this interaction, the firm's view about the market environment contributes to market revitalization. But the previous research doesn't concretely discuss the mechanism of horizontal interaction between firms entering the market. This interaction centers on competition and cooperation among firms. Assuming that a certain firm's action is a trigger factor for market revitalization, there are great ripple effects from new directions of innovation and innovation's intensification through interlocking of actions as entering firms compete or cooperate in the market.

結品性物質が塑性変形する際の微視的機構であるdislocationのダイナミクスについて解説する。dislocationとは「線状の格子欠陥」であり、また「すべった面とまだすべってない面とを分ける界面」でもあるので、物理の言葉で言えば欠陥ダイナミクスであり、界面ダイナミクスである。そのようにみた場合、dislocationダイナミクスは二つの特異性をもつ。すなわち、ひずみ場を介した長距離相互作用と、格子に起因する離散性である。dislocation理論は1945年にOrowanらにより提唱されて以来古い歴史を持ち、とくに材料工学の文脈で多数の教科書やモノグラフが出ているが、非線形動力学という観点からはほとんど論じられていないようにみえる。この小論ではdislocation理論を非線形動力学の観点から紹介する。ただし筆者白身非平衡物理の出身であって材料科学の専門教育は受けていないので、dislocation理論の包括的な入門を書くことなどは不可能である。そのような知識の網羅は材料科学の教科書に譲り、ここでは「古い題材に対する新たな見方」の提供を試みる。この小論が物理説にdislocationへの興味を喚起するきっかけとなれば幸いである。
