本研究では,再発事象の発現が定常ポアソン過程に従うと仮定し,再発事象の発現頻度が変化する点(変化点)の存在に関する仮説検定を考え,検定統計量の帰無分布について考察した.再発事象がn件発現した場合の検定統計量の帰無分布は,互いに独立でないn-2個の自由度1のカイ2乗分布(χ^2_1分布)の最大値の分布で与えられる.しかしながら,その分布を導出することは難しいため,帰無分布の下界及び上界が,それぞれ,独立なn-2個のχ^2_1分布の最大値の分布及びχ^2_1分布で与えられることを理論的に示し,下界及び上界を用いた線形結合により,帰無分布を近似することを検討した.本研究で導出した下界及び上界を用いた近似は,必ずしも近似が十分でないこともあることから,さらに,経験分布関数による近似について検討した.シミュレーション研究の結果,検定統計量の帰無分布は,発現件数nに応じたガンマ分布による近似が可能であると考えられ,ガンマ分布のパラメータを,発現件数nに基づき決定する回帰式を求めた.このガンマ分布を用いた経験分布による近似は,全ての領域で帰無分布の良い近似を与え,また,検定における第1種の過誤確率を名目の有意水準に保つ観点からも,下界及び上界を用いた近似に比べて,帰無分布の良い近似を与えることがわかった.

A list of Heteroptera species found in the Kuril Islands, a history of investigation and brief zoogeographical analysis are presented. Heteroptera were found on 24 islands of 30 studied. The check-list encompasses 236 species belonging to 27 families. The number of species found on individual islands ranges from 1 to 218 (Kunashir). The fauna of the southern islands is much more diverse than that of the northern islands. The fauna of the Kuril Islands is more diverse than the faunas of Kamchatka (110) and Sakhalin (226), but much less diverse than the fauna of Hokkaido (450). Ninety-eight species occurring in the Kuril Islands have wide ranges, 98 species are restricted in their distribution to southeast Palaearctic, and 40 species have exclusively island ranges, occurring only in the Kurils and adjacent islands. Only one species of bugs is known to occur exclusively in the Kuril Islands: Aneurillodes glaberrimus Kerzhner, 1979.

According to the course of study for high school biology, the purpose of study is to develop inquiry ability and positive attitudes toward science through experiments and observations. However, because of increased access to the virtual world, modern high school students have had less contact with nature in their childhood. Therefore, it has become harder for them to have an concrete understanding of biological concepts. This makes it difficult to see the relevance of living things and biological phenomena in class.Many high school students would not believe that egg embryos could become fully hatched birds with only a 34- or 46-hour incubation period, even with careful observation. Therefore we developed lesson plans not only to observe avian embryos, but also to continue incubation until the eggs hatched. We also made students study about egg incubation methods themselves using Bio-STEM ideas.As a result, these inquiry lessons did not only encourage expansion of the students’ biological knowledge, but also generated ideas connected to STEM fields. We found them to be effective in the promotion of learning aims in the context of Japan. They also brought cross-cutting scientific thoughts, similar to the context of United States STEM education, to our local classrooms.

The weaving spiders live by making their webs according to their own weaving mode. The weaving mode consists of web form, web size, web angle, web height, web thread character, etc., and it is generally similar within a species, a genus or a family. The basic weaving modes are as follow: vertical (both single layer and multi-layer), horizontal (both small and large), cubic (both true cubic and line), sheet (inverted dish, with or without cradle; saucer, with or without cradle), and fixed (flat and curved surface) (See table 1). But the basic mode may be modified by situations such as growth and developmental stage, or slight individual variations, etc..In the classification of the spider's webs only their shapes have been noticed. This paper suggests a modification of this classfication by adding the important factors of the spatial Orientation and the spatial surrounding micro-habitat to which the web is attached.Web of any types are attached to some objects (such as tree branches or windowframes); these objects form scaffolding stands which have several possible characters: form, size. mobility, condition of surface, etc.. There are several shape types of scaffolding stand as follows: lengthwise, box with ceiling, widthwise with ceiling, widthwise with underbase, flat surface (See Fig. 1).On the other hand, from the viewpoint of weaving condition the surface of the earth has several types of habitat (Table 3). And each habitat consists of various micro-habitats. For example, a forest consists of 4 micro-habitats as follows: open area among trees, peripheral foliage, central foliage, basal area (soil, trunk, lowest branches, and open space) (See Fig. 2). such micro-habitats offer the scaffolding stands for making webs.These scaffolding stands, along with the shape and spatial orientation of webs themselves make up the weaving environment of the weaving spiders.

Since the isolation of the cDNA of macrophage migration inhibitory factor (MIF), a number of novel biological properties of this cytokine have been discovered. The primary amino acid sequence of MIF is well conserved among a wide range of species. MIF is constitutively expressed not only in T cells, but also in a variety of other cells, including macrophages and epithelial cells of various organs. With regard to its biological function, MIF plays an important role as a proinflammatory cytokine, initiating production of other inflammatory cytokines, and as an anterior pituitary-derived hormone, potentiating lethal endotoxemia. In particular, it should be emphasized that this protein has the potential to override the glucocorticoid-mediated suppression of inflammatory and immune responses. Judging from an array ofin vivostudies, it is clear that anti-MIF antibodies efficiently suppress endotoxin-and exotoxin-induced inflammation and immune responses as well as tumor growth and angiogenesis. This review presents the latest findings on the roles of MIF in inflammatory and immune responses, as well as in cell growth and differentiation.

群馬県において昭和54年に出生した2,500g以下の低出生体重児の母と,その低出生体重児と地域や出生時期を極力マッチさせ出生体重が3,000~4,000gの正常児の母との間で症例一対照研究を行ない以下の結果を得た.1)低出生体重児には女児が多く,新生児期の死亡率は8.1%で,体重別にみた予後は1,500g未満の場合に悪い,2)低出生体重児に関与すると思われる妊娠前の危険因子としては年齢,体格,月経歴,既往歴等がある.3)社会医学的要因には職業,学歴,喫煙,睡眠時間,母子健康手帳の交付時期,健診回数等があげられる.4)妊娠中の危険因子としては,流早産徴候としての出血,腹痛や貧血,妊娠中毒症等が関与している.5)低出生体重児には多胎,骨盤位,前置胎盤,早期剥離などに伴うことが多い.A case-control study was made in Gunma Prefecture of 1,390 mothers of babies born weighing 2,500 grams or less and an equal number of mothers of 3,000-up to-4,000 gram babies matched by place and month of birth. A correlation was found between low birth weight babies and maternal age, stature, menstrual history and past history. The mother's occupation, educational career, smoking habits, amount of sleep each day, date of issue of the Mother's Handbook and the number of the periodical health examinations received can be listed as socio-medical factors. Bleeding and lower abdominal pain during pregnancy, anemia and toxemia of pregnancy are found as prenatal factors. Low-birth-weight babies are found to be correlated with multiple pregnancy, breech presentation, placenta previa and premature separation of the placenta, also.

A neural network model to read aloud proposed. Although two succeeded models\r were proposed so far, some problems still remained unsolved. The problems are the way\r of implementation about the“lookup table”in the dual route cascaded model, and the\r existence of“division of labor”in the triangle model. The model proposed here was\r intended to integrate both models in order to give a solution to these problems. The model\r is consisted of two local perceptrons to deal with information of orthography and\r semantics, and a gating perceptron to adjust outputs of local perceptrons. Introducing a\r Gaussian function and its interpretation, this model can describe contribution of semantics\r clearly. This model can also explain the grapheme-to-phoneme-correspondence rule to\r read regular words, and the way of reading irregular words. According to this model,\r there is no difference between the dual route cascaded model and the triangle model. The\r outward difference between these models can be absorbed in a variance parameter. The\r variance parameter will be adjusted or learned through training many times. Therefore,\r this model can formulate for the problems in which both models could not describe. This\r model can be regarded as an extended and generalised version of previous models which\r are absorbed in this model.

脳の情報処理機序の解明には,非線形な神経電気活動パターンのダイナミクスを理解することが重要である.また,近年ディープラーニング(DL)が多分野で高い識別精度を発揮している.そこで本研究では,ラット海馬から調製した生体神経回路網に対して,電気刺激を印加することで観察される誘発応答電位を含む神経電気活動を計測し,異なる刺激に対する応答パターンの識別に対するDL手法の有効性を検証した.時空間的情報の連続性を保持するようにしながら,入力データを画像として作成し,事前学習手法として積層オートエンコーダを用いた積層人工ニューラルネットワークで,神経電気活動パターンの特徴抽出を試みた.その結果,パターン識別の精度は充分ではなかったが,刺激直後2秒のデータのみを識別対象とすることで,識別精度は刺激直後10秒のデータを対象とした場合と比較して約2倍に向上した.神経電気活動のように「ゆらぎ」の大きい現象について,DLの手法によってパターン識別を行う場合は,分類判別基準に対するデータのゆらぎに応じた相当数の入力データが必須であることが確認された.
