脳性麻痺には種々の症状があるため，一人一人の症状に合わせたコンピュータインタフェースが望まれている．本研究では，脳性麻痺の症状を持つ2名の対象者に対して，コンピュータマウスに対する要望をインタビューした．その結果，「Shift・Ctrlキーの状態保持」，「クリックボタンが全方向から押下可能」，「左利き用マウスが即時利用可能」などの要望が抽出された．そこで，これら要望について対策したシステムを実装し，対象者に評価してもらった．, Generally speaking, cerebral palsy has various symptoms. Users with cerebral palsy await the development of personalized computer interfaces. In this research, first, 2 users with cerebral palsy was interviewed for their desire in using computer mouse. As a result, three requests ,“State retention of Shift or Ctrl key”, “Click button of mice can be pressed from any directions”, “Left-handed mouse available immediately” were extracted. Second, we developed interface that matches the three specifications. Finally, the system was evaluated by 2 users with cerebral palsy and got highly rated.

Finished condition of concrete surface is an important factor for architectural concrete. Therefore, the purpose of this study, it is to construct evaluation index and method of uneven color on concrete. This paper clarified effect of testing conditions on sensory evaluation of uneven color. As a result, the sensory scale was shown to symmetry to physical quantity of multiple linear regression analysis., 本研究は，コンクリート表面の視覚的な仕上がり状態を規定する要素の一つである色むらを対象とし，定量的な評価指標および評価方法の構築を最終目的とする．その端緒として，色むらの程度を明度の標準偏差で表現し，明度の統計値が既知の試料を用いて官能検査を行った．ここでは，検査条件の相違が観察者の色むらに対する認識に及ぼす影響を検討した結果を報告する．また，官能検査により構成した心理学的尺度(以降，色むら認識尺度とする)と物理量の対応を試みた．

This paper is reported the result of approaches to nondestructive surface-evaluation of concrete in structure by comparing with strength of core and estimated strength based on lightness changing of concrete surface by water sprinkling. As a result of using cylinder specimen as a fundamental study, the time that lightness of concrete surface after water sprinkling converges before itself gets shorter as water-cement ratio becomes high. Based on this result, using specimen that simulated concrete in structure, we compared with compressive strength of core specimen and lightness changing on surface of that core and found out that average of lightness changing at range and point of image processing and compressive strength of core specimen have relativity., 本研究では，既報⁸⁾の続報として，材齢56 および91 日まで検討した結果を示すとともに，これを発展させ，構造体コンクリートを模擬した部材(以下，模擬部材とする)において，コア強度とコンクリート表面の明度変化の相関性について検討を行い，構造体コンクリート強度の面評価を試みた結果を報告する．

This paper showed the concept of evaluation index to the visual element in the finishing of concrete surface. As a final objective, it is construction of the quantitative quality control system by the image analysis of principally uneven color and surface foam. The image analysis program can evaluate a color tone besides uneven color quantitatively, and there are a sensuality evaluation and correlation. For this reason, we thought that construction advances smoothly by this quantitative quality control system., 本報告は，打放しコンクリート表面の仕上がり状態を規定する視覚的な要素について，定量的な評価と官能評価による感覚量を複合した評価方法を確立し，最終的には，関係者間の合意形成に基づく仕上がり状態の品質管理システムを構築することを目的としたものである． ここでは，打放しコンクリート表面の仕上がり状態を規定する要素の一因である“色むら”を主眼とし，画像解析による定量的な評価方法と官能検査による評価尺度との関係について示し，この評価方法を用いたコンクリート表面の仕上がり状態における品質管理システムのあり方について述べる．

In this paper, we have clarified experimentally that the field coil magnet loud speakers have higher quality than ordinary ferrite loud speakers. Firstly, we evaluated both type loud speakers under the condition that only magnet were different. We have obtained "+2" rank better in the seven grade scale on field coil magnet loudspeakers. As a result of the measurements, we proved that field coil magnet loud speakers have large amplitude and better damping., 本報告では，音楽再生における質の観点から，音楽愛好家の間でも評価の高い電磁石スピーカに注目し，深い感性に関連する物理要因・特性を測定と分析により明らかにする．具体的には，同一形式，同一口径の（磁気回路のみ異なる）電磁石スピーカとフェライト磁石スピーカを用意し，それぞれの音質を深い感性と関連する音質評価語群を用いた主観評価により追求し，評価に深く関連している物理特性を測定分析した7)．更に，前述のスピーカとは違う種類だが，同一形式，同一口径のアルニコ磁石スピーカと，フェライト磁石スピーカを用意し，測定分析する．以上のことより，スピーカにおける磁石の違いを心理物理学的に考察・検討する．

『今まで耳でしか聴いたことがなかった音楽を今回，身体全体の細胞で聴くことができました．透き通った音色は生きており皮膚を撫でて行くようです』の状況は、“こころが感じる”で、芸術と科学の融合を掲げる芸術科学会の基礎テーマであり、正面から対応する。この状況をオカルトとして対応しない大多数の日本の自然科学者を標榜する人も納得させうる、哲学的に客観性を証明した、新・電気音響論である。 それは、客観評価尺度を定義し、人のこころに感動を喚起する高度感性情報を伝える音の音響理論であり、実際に装置を研究開発した。物理歪量のみの定義のみで音質を言及しない従来ハイファイとは別次元の音響理論である。

Conventional audio system is constructed based on the communication theory where the performance of thesystem is described by signal error which does not always represent a true sound quality. In order to make anaudio system which represents true music admirations in one's mind, we have taken a special approach. Since itis considered that true admirations are represented by adjectives, we have obtained two principle phrases byperforming the multivariate analysis on the whole Japanese adjectives. Based on the methodology, we havediscovered necessary physical electric characteristics with which we have successfully achieved a new AudioSystem.

Fundamentally speaking, audio system should be faithfully reproduced deep sensations of human that evoke deep musical emotions such as “atmospherics”, “feel of tension” and “texture of sound”, etc. It is possible to construe faithful reproduction of deep sensations in audio system as an example of process to translation from tacit knowledge into the other tacit knowledge. Therefore, development of audio systems which can faithfully reproduce deep emotions is possible to say the same as “Socialization” in SECI model. However, most of existing audio system can not reproduce such as deep musical emotion. For this purpose, we have been developed such as audio systems focused on the deep musical sensations. In our researches, we found jitter in digital audio systems deteriorate sound quality seriously. In this paper, at first, we investigate the relation between sound quality concerned with deep sensations and jitter in digital audio systems. Accordingly, we speculated that the influence of jitter was transformed to other shapes before or within the D/A converter block. One of the possibilities is that the influence of the jitter affects the sound quality, indirectly, via the power supply line. Secondarily, we attempted to clarify the relation of sound quality and an ideal power supply of audio systems. The measurement result showed the proposed power supply can suppress the turbulence comparing with conventional ones. The assessment result showed that the MOS value of sound quality of the proposed power supply was higher than conventional ones., The original publication is available at JAIST Press http://www.jaist.ac.jp/library/jaist-press/index.html, KICSS 2007 : The Second International Conference on Knowledge, Information and Creativity Support Systems : PROCEEDINGS OF THE CONFERENCE, November 5-7, 2007, [Ishikawa High-Tech Conference Center, Nomi, Ishikawa, JAPAN]
