本稿では,ソフトウェア工学の研究,実務における13の重要な課題を明らかにする.すなわち,(1)ソフトウェアの品質とは何か?(2)現在のソフトウェアの技法の背景にあるROI(投資利益率),そして経済とは何か?(3)プロセス改善(process improvement)は重要か?(4)ソフトウェアメトリックスを信用できるか,あるいは解釈ができるか?(5)ソフトウェア工学の基準は余りにも混乱しており,実装,法令順守(compliance)が困難ではないか?(6)なぜ,競合する基準に相互運用性のプリディクター(interoperability predictor)がないのか?(7)遺産的ソフトウェア(legacy software)とそのデコミッショニングをいかに処理するか?(8)テスト終了について使用すべき妥当な基準があるか?(9)COTS(Commercial Off-The-Shelf Software:市販の既成ソフトウェア)にはほとんど相互運用性,結合可能性(composability)がない.なぜか?(10)信頼性評価法,オペレーショナルプロファイルはしばしば疑わしいとみなされる.何が本当のオペレーショナルプロファイルなのか?(11)「…性」を基本にした設計は,ないものねだりの希望的観測である.技術的,あるいは経済的にどのように対応すればよいのか分からない問題である.(12)ソフトウェアの認証(software certification)は必要である.しかし,どのようにしてそれを実施するか,また,それに関連した責任をどのようにとればよいか分からない.(13)インテリジェンス,自律形コンピューテイングは結構である.でも実現可能か?

<p>Today changes are so frequent and extensive so that we cannot predict the future. To cope with this situation, we have to team up to solve the problems. But if we team up with 11 best players, the team will not be the best. The best team is realized when every member of a team can adaptably change his role. Such an adaptable team will be the final winner. But our engineering education has focused on how we can grow up best players and we did not pay too much attention to how we can make our team adaptable enough and how we can increase such adaptability of each player. We should make our efforts to grow such adaptable engineers.</p>

Extraction of emotion from facial expression and voice are attempted in this research. Although there are researches on extracting emotion using still pictures, there are quite few which analyze motion pictures. The eye and mouse motion were observed. Voice analysis was done based upon sound pressure.

This paper describes a new approach in visualizing self-awareness. In particular, Habit of Speaking (HoS) is focused. In the pilot experiment of the chat system 48 kinds of HoS were extracted, and they were altogether called 'Group of HoS.' In the main experiment, all subjects evaluated HoS one by one using the Internet. Then they had to choose one from 4 kinds of Frequency; a) Many times, b) Sometimes, c) Unusual, d) Never, and one from 5 kinds of Impression; a) Best, b) Better, c) So so, d) Worse, e) Worst. Thus, all HoS were ranked by Impression and Frequency, which lead to 4 categories. This experiment demonstrates that although most subjects would like to grasp their own HoS, they felt it too difficult to grasp their HoS by themselves.

The present paper describes a new design of a fluid driven microactuator which comprises a planar piston, a four-way control valve, and a mechanical feedback system that controls the output in accordance with an input displacement. Fabrication processes of the microactuator include bulk micromachining of two sheets of silicon substrate and their assembly by electrostatic bonding to glass plates. The output characteristics were measured supplying the compressed air. Generated output force was partially linear to supplied pressure and to valve displacement. However, the magnitude was asymmetric in terms of driven directions, which results from geometrical configuration essentially introduced by an anisotropic etching of the silicon. The position of the output shaft was sufficiently controlled with a designed magnification factor multiplied to the input displacement in both static and dynamic senses.

A method for supporting industrial design with special attention paid to the diversity of Kansei was proposed to respond to the quickly diversifying customers' requirements. As Kansei is very individualistic in nature, a new approach is needed to accommodate the difference from person to person to really reflect the customer's preference In terms of Kansei or his or her personal evaluation Kansei feature. Therefore, such a method was developed which creates a different Kansei space for each different user, by applying a semantic differential method and a principal component analysis to the impression words. A prototype system was developed with cellular phones as samples and the usefulness of our method was demonstrated.
