The analysis of evaluation of instruction by students can be the most powerful tool available to instructors for the improvement in their own instruction technique. A questionnaire named minute paper soliciting students' evaluation of instruction was given out to the students of 3 courses at Tokai University during 1989 every time. The minute peper has five questions: what are points of important and doubt of this instraction?, how is evaluation by yourself as student in this class?, how is evaluation of this instruction?, What are good items of this instruction?, What are bad items? In this paper, how to use the minute paper, useful point of the minute paper, relationship between evaluation value of the minute paper and total evaluation value of a semester are introduced. The minute paper had 8 useful points : it is possible to make improvement of instruction every time, to see students' understanding and others. The total evaluation value of a semester was higher than it of the minute paper.

本論文はMC/LISPと呼ぶCOMMON LISPに基づいて実現されたLISP処理系の翻訳系の構成を述べたものである.翻訳系はプログラム変換系とコード生成系より成っている.LISPのプログラムはFP/Cと呼ぶカテゴリ風プログラムに変換される.次にFP/Cのプログラムが翻訳関数によって翻訳されコード生成が行われる.プログラム変換は実行時の環境を単純なものとするために,および翻訳の過程を形式的に把握するために不可欠である.この考えに基づきLISPの基本的計算機構のプログラム変換の規則とコード生成の規則を形式的に与えている.

The present authors proposed the adjoint boundary integral method for identifying heat source or force in a domain from values of boundary integrals involving an adjoint operator. The integrals can be evaluated if boundary values are available over the entire boundary of the domain. In the present study a Poisson field source is identified from noisy and discrete boundary observations by applying the method. Adaptive Gauss quadrature enables evaluation of the boundary integrals from observations at discrete points, which deviate from the Gauss points for approximate evaluation of boundary integrals. Numerical simulations are carried out for identifying location and intensity of a concentrated source in a two-dimensional domain. Effects of errors in boundary observations, deviation of locations of observation points from the Gauss points, the order of Gauss quadrature, and the location of source on the accuracy of the identification are discussed. It is shown that the location and intensity of the source can be estimated reasonably from noisy and discrete observations by applying the adjoint boundary integral method with the adaptive Gauss quadrature.

本研究では, マルチエージェント競合系の例としてカードゲームであるハーツを取り上げ, Actor-Cmicアルゴリズムと先読みを用いた強化学習法を提案する. この系では, 部分観測マルコフ決定過程における強化学習を取り扱わねばならない. 提案手法では, ゲームを序盤, 中盤, 終盤の3つの局面に分割し, それぞれの局面でActorを切り換えて行動制御と学習を行う. 中盤においては, 期待TD誤差に基づく先読みを用いた行動選択を行う. この際, Criticによって近似された状態評価関数と相手戦略から推定した状態遷移確率を用いて期待TD誤差を計算することで部分観測性に対処する. 本手法の有効性を計算機シミュレーション実験により確認した.

コンピュータ教育においてプログラミング学習は大きな要素を占める.しかし,個々の理解度に差が生じやすく,学習意欲が低下しやすいという傾向がある.本研究では,遠隔ペアプログラミングやテストファースト指向の課題演習といった,XP(eXtreme Programming)の手法を取り入れたプログラミング学習支援システムを提案する.本システムの利用によって,相互学習による理解度の向上,学習意欲の改善がみられた.本報告では,学習におけるXPの有用性について調査し,通常のペアプログラミングと遠隔ペアプログラミングとの効率の比較,考察を行う.

The third, and final, part of this series deals with theoretical thinking of Otto Neurath, especially concentrating to his discussion on basic problems of scientific learning. This gives also an explanation of philosophical diversification of people of the Vienna Circle, or logical empiricism, which is often thought as a monolithic, rigorous, inflexible rationalist group. On the contrary, Vienna Circle was a movement, opened to all anti-metaphysical people. Influenced by Weber, Simmel and others, who bore the best tradition of German social science in the last phase of the German Empire, Neurath developed his early theoretical activity. He pursued an ideal of pure science on the one hand, and wanted to realize the social reform on the other. It was the common attitude of young scholars who were to join First Vienna Circle. Responding to the evident decline of the mechanistic world picture in the end of the nineteenth century, these young scholars tried to establish a bridge between Machian empiricism and conventionalism of Poincare. Through an intensive study of Duhem's work, Neurath and Hahn reached an assertion, which was an extension of Duhem's thesis from physics to science in general. In the Second Vienna Circle, which had started in early 1920s, Neurath worked as an active member of this group. Several critical discussions or debates, with which he concerned, are discussed: "protocol sentence debate", "Neurath's Boat", "Ballungen", and etc. While he was the hardest critic against all kind of metaphysical thought and preferred the Enlightenment, he was also the left wing critic against the inflexible pattern of logical empiricism. In a sense, he was a forerunner of the post-WWII science studies, which were developed by Thomas Kuhn, Paul Feuerabend and other scholars.

In order to get an insight into the cellular mechanisms for the integration of the effects of gravity,we investigated the gravitactic behaviour in Paramecium. There are two main categories for the model of the mechanism of gravitaxis; one is derived on the basis of the mechanistic properties of the cell (physical model) and the other of the physiological properties including cellular gravireception (physiological model). In this review article, we criticized the physical models and introduced a new physiological model. Physical models postulated so far can be divided into two; one explaining the negative gravitactic orientation of the cell in terms of the static torque generated by the structural properties of the cell (gravity-buoyancy model by Verworn, 1889 and drag-gravity model by Roberts, 1970), and the other explaining it in terms of the dynamic torque generated by the helical swimming of the cell (propulsion-gravity model by Winet and Jahn, 1974 and lifting-force model by Nowakowska and Grebecki, 1977). Among those we excluded the possibility of dynamic-torque models because of their incorrect the oretical assumptions. According to the passive orientation of Ni2+-immobilized cells, the physical effect of the static torque should be inevitable for the gravitactic orientation. Downward orientation of the immobilized cells in the course of floating up in the hyper-density medium demonstrated the gravitactic orientation is not resulted by the nonuniform distribution of cellular mass (gravity-buoyancy model) but by the for-aft asymmetry of the cell (drag-gravity model). A new model explaining the gravitactic behaviour is derived on the basis of the cellular gravity sensation through mechanoreceptor channels of the cell membrane. Paramecium is known to have depolarizing receptor channels in the anterior and hyperpolarizing receptors in the posterior of the cell. The uneven distribution of the receptor may lead to the bidirectional changes of the membrane potential by the selective deformation of the anterior and posterior cell membrane responding to the orientation of the cell in the gravity field; i.e. negative- and positive-going shift of the potential due to the upward and downward orientation, respectively. The orientation dependent changes in membrane potential with respect to gravity, in combination with the close coupling of the membrane potential and the ciliary locomotor activity, may allow the changes in swimming direction along with those in the helical nature of the swimming path; upward shift of axis of helix by decreasing the pitch angle due to hyperpolarization in the upward-orienting cell, and also the upward shift by increasing the pitch angle due to depolarization in the downward-orienting cell. Computer simulation of the model demonstrated that the cell can swim upward along the “super-helical” trajectory consisting of a small helix winding helically an axis parallel to the gravity vector, after which the model was named as “super-helix model”. Three-dimensional recording of the trajectories of the swimming cells demonstrated that about a quarter of the cell population drew super-helical trajectory under the unbounded, thermal convection-free conditions. In addition, quantitative analysis of the orientation rate of the swimming cell indicated that gravity-dependent orientation of the swimming trajectory could not be explained solely by the physical static torque but complementarily by the physiological mechanism as proposed in the super-helix model.

画像検索を高速化するためのフィルタリング法として,特徴ベクトルの次元削減に基づく距離の不等式とクラスタリングに基づく三角不等式とを利用する手法を提案する.画像の非類似度をカラーヒストグラム間の2次形式距離で測り,それに基づいてクラスタリングと類似検索を行う.まずデータベース画像をk平均法でクラスタリングする.このとき特徴ベクトルの次元削減に基づくフィルタリングによって計算時間を短縮する.クラスタリングによって得られる代表点を画像のkNN検索でのフィルタリングに利用する.このときにも特徴ベクトルの次元削減に基づくフィルタリングを組合せて用いる.実験により,次元削減によってクラスタリングが高速化されることと,クラスタリングと次元削減の両方に基づくフィルタリングを用いることにより,画像検索の時間が短縮されることを示す.
