Abstract The importance of the presence of butenolide groupings in biologically active substances has been recognized increasingly. (1) In our search for new pesticides we have prepared 26 α-arylamino-γ-aryl-⊿(α,β)-butenolides (1-26) and 9 α-arylidene-γ-aryl-⊿(α,β)-butenolides (27-35) which seemed to us of interest as test materials for the screening. α-Arylamino-γ-aryl-⊿(α,β)-butenolides were prepared by the reaction of sodium or potassium arylidenepyruvate with arylamines in the medium of glacial acetic acid as is reported by Meyer and Vaughan(2) (Scheme I, see also Experimental Section). α-Arylidene-γ-aryl-⊿(β,γ)-butenolides were prepared by the condensation of aromatic aldehydes with β-aroylpropionic acids in the presence of anhydrous sodium acetate. The analogous procedure for this purpose has been reported by several authors(3) (Scheme II). The physical properties, yields, and analytical data of these compounds have been summarized in Table I (1-26) and Table II (27-35).

Abstract An information processing task which generates combinatorial explosion and program complexity when it is treated by a serial algorithm is investigated using both Genetic Algorithms (GA) and a neural network model (NN). The task in question is to find a target memory from a set of stored entries in the form of "attractors" in a high dimensional state space. The representation of entries in the memory is distributed ("an auto associative neural network" in this paper), and the problem is to find an attractor under a given access information where the uniqueness or even existence of a solution is not always guaranteed ( an ill-posed problem ). The GA is used as an algorithm for generating a search orbit to search effectively for a state which satisfies the access condition and belongs to the target attractor basin in state space. The NN is used to retrieve the corresponding entry from the network. The results of our computer simulation indicate that the present method is superior to a search method which uses random walk in state space. Our technique may prove useful in the realization of flexible and adaptive information processing, since pattern search in high dimensional state spaces is common in various kinds of parallel information processing.

Abstract Numerical simulations of a single layer recurrent neural network model in which the synaptic connection matrix is formed by summing cyclic products of succesive patterns show that complex dynamics can occur with the reduction of a connectivity parameter which is the number of connection between neurons. The structure in these dynamics is discussed from the viewpoint of realizing complex function using complex dynamics.

Abstract 光ディスクとパーソナルコンピュータを組み合わせた内視鏡画像ファイリングシステムは電子内視鏡の画像の保存・管理,検索・再生などに威力を発揮する。今回,われわれはオリンパス社製内視鏡ファイリングシステムSDF-3を使用する機会を得たので,その有用性や問題点の検討を行った。有用性としては,①内視鏡画像を検査終了後直ちに再生し,再検討できる,②多数の項目についての検索や統計処理が可能である,③限られたスペース内で大量の画像データの一括保存・管理が可能であるなどが挙げられる。一方,問題点としては,①内視鏡再生画像は画質が劣化する,②検索機能を十分に活用するにはかなり煩雑な人力操作を必要とする,③光ディスクの清掃が必要であるなどがあげられる。本内視鏡ファイリングシステムに今後必要な改良点やその展望についても合わせて考案を加えた。

Abstract 医療の高度化に伴い,放射線治療分野においても急速な技術革新が行われている。QOL(Quality of Life)を考慮に入れた治療が求められる多くの場合,放射線治療が大きな選択肢の一つであることは言うまでもない。このような状況下の中で,正常組織に影響を与えず病巣に限局した放射線を照射する技術が開発され,外照射においては,欧米に習い我が国でも研究段階から臨床へ移り変わろうとしている。その際に,投与線量評価を欠かすことができないが,従来から使用されているいずれの線量計も新しい治療法に対応しきれていない。そこで,フィルムタイプ線量計, Gafchromic MD-55-2 film の開発により,いくつかの問題が解決されてきている。しかし,この線量計を精度良く測定する濃度測定器が必要になるが,現段階において規格化されたガイドラインが存在しないのが現状である。そこで本研究では,当施設で保有しているⅩ線フィルム線量測定用 Laser Densitometer Model 1710 を用いて Gafchromic MD-55-2 fllm による線量測定を行い,問題点の抽出を行うとともに線量測定精度の考察を行った。

Abstract 本研究は,「介護者の会」参加によってもたらされる介護への影響を,現役介護者と介護終了者の相互作用に焦点を当てて探求しようとするものである。特に介護終了者が介護を終えた今もどういう意図で会に参加し,実際に何が得られているのか,また介護終了者の参加がもたらす現役介護者への影響は何なのかを,明らかにすることを目的とした。2つの「介護者の会」に依頼し,現役介護者10名,介護終了者13名を対象として,半構造的面接を行った。その結果1)現役介護者は,会への参加によって将来への不安が軽減し,相談できる人が出来た,適切な介護用品を活用できるようになった等の変化が見られた。 2)現役介護者は介護終了者が「介護者の会」の世話役を行ってくれることで安心して会に参加でき,介護終了者から安心感や介護ヒントを与えられていた。3)介護終了者は,次第に聴く立場から語る立場へと変化すると同時に,自らの介護の振り返りも行っていた。4)介護終了者もまた「介護者の会」から情報や現役介護者からの信頼感を得ており,会の成長・活動意欲へと繋がっている,といったことが明らかになった。

Abstract 本研究では、学習指導要領と教科書の分析、新聞記事の検索やアンケートを行うことによって、高校理科における「微生物」に関する学習の現状と問題点を探求した。 その結果、地球環境/健康/食料生産に関与する微生物については多く科目で取扱われていた。その一方でバイオマスからエネルギーを製造に関与する微生物については、社会的に注目されているにもかかわらず十分な学習内容が構成されていなかった。

Abstract A variety of studies on face components such as eyes, lips, noses, and teeth have been proceeding in medicine, psychology, biometrics authentication, and other areas. In this paper, we present an algorithm of extracting eye contours from a face image using the deformable template matching method. Our template for an eye contour is composed of three quadratic functions for the perimeter and one circle for the pupil. In our algorithm, a digital color face image is rst converted to a binary image of representing eyes, after the region around eyes is identied on the face image by using hues and values of the color image. Then, parameters in the template are optimized by a local search method with a tabu period and a hill-climbing, so as to t the template to the eye contour in the binary image. The accuracy of our algorithm is evaluated through sample face images of students. In addition, the application of our proposal to eye shape indices is investigated in a face image database "HOIP", where recognizable dierence exists in index distributions between males and females.

Abstract Dense point matches are generated over two images by rectifying the two images to align epipolar lines horizontally, and horizontally sliding a template. To overcome inherent limitations of 2-D search, we incorporate the “naturalness of the 3-D shape” implied by the resulting matches. After stating our rectification procedure, we introduce our multi-scale template matching scheme and our outlier removal technique using tentatively reconstructed 3-D shapes. Doing real image experiments, we discuss the performance of our method and remaining issues.

Abstract We classify and review existing algorithms for computing the fundamental matrix from point correspondences and propose new effective schemes: 7-parameter Levenberg-Marquardt (LM) search, EFNS, and EFNS-based bundle adjustment. Doing experimental comparison, we show that EFNS and the 7-parameter LM search exhibit the best performance and that additional bundle adjustment does not increase the accuracy to any noticeable degree.
