Vibration power generation utilizing environmental vibrations to generate electricity has been attracting attention as a sustainable independent power source for such as wireless sensors placed under vibration. For efficient power generation, the resonant frequency of the vibration power generation device must be automatically adjusted to the environmental vibrations. To achieve it, the author's group proposes a method of installing a variable capacitance in the device and adjusting its capacitance by extremum seeking control. In the case of damped vibration applied, even if the amplitude and frequency of the vibration vary randomly if their distributions can be regarded as stationary and identical, an effective extremum seeking control method and its effectiveness are demonstrated using experiments.

Various factors influence the mood, and the interoception, which is sense inside the body may play an important role in clinical psychology and psychosomatic medicine. In this study, we defined the mood as “the persistent and untargeted integration or unity of the state of mind and body situated between affection and emotion”, and examined its relevance to the interoception. A questionnaire survey was conducted in 152 college students using the “Mood Inventory” and “Multidimensional Assessment of Interoceptive Awareness - Japanese Version (MAIA-J)”. The results showed that “refreshing mood” was positively correlated with “attention regulation”,“body listening”, “emotional awareness”, and “trusting” of the interoception . In addition, the mood of “fatigue” and “depression” was negatively correlated with “attention regulation”, “body listening”, and “trusting”. “Anxious mood” was positively correlated with “noticing”, but negatively related to “not-distracting”. There was no correlation between mood “tension and excitement” and interoception. This study suggests that various subjective moods are related to various aspects of interoception in MAIA-J.

It is welcomed that victims policy has developed recently in Japan. In this trend, however, there is a danger that "viewpoints of actual victims" are substituted for "viewpoints of potential victims(namely citizens)" in victims policy. Its typical example is Megan's Law in the U.S.A. In this paper, I examine the legislative process and the problems of Megan's Law. My examinations are following. As problems of the political character of the legislative process of Megan's Low: 1.The panic among citizens provoked by the sensational sexual crime helped Megan's Law pass in a rapid speed; 2.The politicians were very active toward Megan's Law's enactment because they wanted to show citizens that they cared for citizens' safety; 3.The Federal Government's role was great too, because they compelled all states to enact Megan's Law in a certain period. Next, as problems of actual functions of Megan's Law: 1.Megan's Law violates offenders' constitutional rights. And many offender have been attacked and ostracized by citizens; 2.The possibility of grasping sexual offenders. Megan's Law targets only a part of dangerous sexual offenders and gives citizens a false sense of security; 3.There may be the problem of "Crime displacement" and also it has not proved yet that Megan's Law prevent offenders from reoffending. From these perspectives, it can be said that Megan's Law makes it easier for law enforcement officers to track sexual offenders even after their release. As information provision systems for victims are developing recently in Japan, I think that examining problems stated above is important to discuss victims policy in Japan. And at last, I stress that the fundamental issue of victims policy is to respect victims' rights and offenders' rights at the same time, so policies which limits offenders rights too much should be criticized.

The polymeric materials, which have been generally considered to be good corrosion resistant material, are also degraded according to environments. The degradation behavior of polymeric materials can be classified into physical and chemical process. The later behavior in which molecular chain are cut chemically are called as corrosion. In this paper, the behavior, form and mechanism of corrosion of thermosetting resins used as matrix of GFRP (glass fiber reinforced plastics) under several solutions are mainly reviewed based on our experiments. The degradation behavior of GFRP are also mentioned briefly.

1970年代以降に, それまでにKodak社によって築かれた技術基盤の上に, 富士フイルム, コニカ, Agfa-Gevaertなどの感材メーカーが夫々独自に開発した新カップラーを携えて技術革新に参入した. 世界の主要感材メーカーは競合しつつも全技術水準の向上によってカラー写真材料事業の成長維持に協力したのであった. カップラーの主要な技術革新の一つに, 新規の骨格分子構造の導入があった. これによって, 鮮やかな色再現, 画像の長期保存, 感材設計の合理化が実現した. 典型的な新骨格には, マゼソタのpyrazolotriazole, シアソのpyrrotriazoleの新型の反応性縮ヘテロ環と, イエローの置換基としてdioxothiadiazine環があった. これら新世代カップラーの発明は, ヘテロ環化学の適用によるところ大きく, 多くの研究者の長期にわたる組織的協力から産み出された.

Potentiometric titration method, by means of potassium ferricyanide as titrant and recording auto-titrator, was applied to the determination of Phenidone in photographic P.Q. developers. In acidic solution, potassium ferricyanide selectively oxidizes Phenidone without oxiding hydroquinone and sodium sulfite. Therefore, the separation of Phenidone from the other ingredients of developer by extraction, that has been needed in conventional methods, is unnecessary. The reaction is not very rapid, but thesharp potential jump in titration curve was obtained in 2N-sulf uric acid.

Microwave photoconductivity of silver halide emulsions reduces contrary in the course of rising at the leading edge of light pulse. The reduction occurred after a constant exposure of about 41μJ/cm2 regardless of the light intensity. The formation of latent image specks is considered to cause the reduction.

日本の南西端に位置する石垣島は、個体数の減少が懸念されている猛禽類サシバの日本における主要な越冬地である。サシバは毎年10月から翌年の3月まで、石垣島の主要な農地環境である牧草地で採食する。演者らは、まず、この地域での越冬期を通したサシバの生息地利用と食物品目などを2002年から2004年に調査した。ラジオテレメトリーや色足環によって個体識別を行ない、のべ6羽の個体追跡を行った結果、すべての個体が越冬期を通して行動圏を農地内に維持していた。一個体の一日の行動圏面積は、越冬期内の時期によって変化し、最小0.09 km2、最大 0.48 km2だった。サシバの越冬期における食物の95%以上がバッタ類であった。サシバは、止まり場に止まり、その周辺で発見した食物動物を採食する、待ち伏せ型の採食様式をとる。調査地のサシバが止まり場として利用したのは、スプリンクラー、電柱、防風林だった。行動圏内の利用様式に注目すると、観察された採食行動の95%は、牧草地での採食だった。牧草地一区画あたりの面積(2700_から_8100 m2)は、サシバの行動圏にくらべて小さく、サシバは、一日のあいだに何度も採食のために待ち伏せする牧草地の選択と放棄を繰り返していた。牧草地では刈り取りが年4回から6回行われているが、この刈り取りの繰り返し期間は牧草の品種、牧草地の立地、栄養条件などによってちがっているため、サシバの行動圏内にはさまざまな草丈の採草地がモザイク状に存在していた。そこで、演者らはサシバによる牧草地の選択と放棄過程に注目し、牧草の刈り取り、草丈、牧草地の配置、待ち伏せ場所であるスプリンクラー数、そして食物であるバッタの密度などが、サシバの採食パッチ選択と放棄にどう関わっているのかを解析した。今回は、これら越冬期におけるサシバの生息地利用と、その利用様式に関わる採食パッチ選択と放棄に影響する要因について報告を行う。

Tayama Katai's Futon, published in 1907, had created a great sensation in the literary world after the Russo-Japanese War. Futon was said to be the first work of “shi-shosetsu,” which is characterized by the confession of the author’'s own sexual life in a direct and simple manner. Fourteen years later, Yu Dafu’s Chen lun appeared in China, and this work also became a sensation overnight. Similar to Futon, Chen lun also brought about a craze of confession novels among the literary circle of young writers. Although no direct relation could be supposed, there exist various similarities between these two works which should not be disregarded. Yu Dafu had studied in Japan for eight years before he became a writer, and indulged in literature while he was in Japan. Previous researches have already clarified influences of Japanese literature on the creative process of Yu Dafu, but in this essay I describe the similarities between these two works, namely their formal structure and their positions in the context of literary history. Katai and Yu Dafu wrote Shojo-Byo and Yinghui-se de Si respectively, in which the heroes onto whom the authors projected themselves suddenly die from fancy for a girl. But in their next works, Futon and Chen lun, the story begins after the heroes’ love affairs have already ended, and the heroes (literary men, who are also are projected authors) to whom love was forbidden are depicted in an ironical manner. Until now many scholars have identified the protagonists with the authors; but if analyzed in detail, it can be understood that the protagonists are described in an objective manner. In these works the emphasis lies on the power of reason to control the instincts. This power enables these works to describe the complicated state of self-consciousness. Futon and Chen lun were written just the moment when the boundary between literature and non-literature was being drawn, and the great success of Futon and Chen lun had a great impact on the literary world because of the style of portraying self-consciousness.
