For pruning shears handle design, the author proposes to create a product database by collecting all information including handle size, mechanics for engineering, and biomechanics. Then, a knowledge database will be created through a parametric coordinate file by applying Extension Markup Language (XML). Finally, a shape design system will be established which integrates Case Based Reasoning (CBR) theory and internet browser user interface. The system can help designers to cope with difficult market environments, preserve original design style, shorten design time, and reduce the possibility of design mistakes. The system also develops a network user interface for which designers can discuss a design project together for improving the design quality and efficiency. In addition, the knowledge database combines Grey Prediction Theory to create a variety of shapes, which can transform automatically according to the design parameters. This system can achieve the purpose of concurrent design, and decrease the mistakes forthcoming from production.

この研究は,コンピュータによるデータベースシステムの効果的教育の達成を目的としている。1994年に設立された広島市立大学では,情報科学部のカリキュラムを米国計算機学会ACMが提案したモデルカリキュラムに準拠して編成・運用している。特に,情報処理技術者の育成に重要なデータベースシステムの教育は学部2年後期に実施されている。
学部2年後期に関係データベースのようなデータベースシステムを習得させるには,講義や机上演習だけでは不十分であるという問題点がある。そこで,学内LANの上に実用規模のデータベースサーバとWWW(World-Wide Web)サーバを導入し,関係データベースシステムに関する教育システムを構築した。本稿では,そのコンピュータ教育の実施方法やその実施結果について報告する。

This paper presents a framework for constructing database of supervisory control systems. The proposed framework utilizes generation-based approach and object-oriented framework library. In this framework, a database of a target system is designed from a design template, and software of a database system is generated from the database design. The generated database system includes dorhain-specific object system, and diagram and plant data editor, which provides effective data input functions.

Among learning management systems (LMSs), there are proprietary learning-support systems that have been developed by researchers at different universities. Often time, these researchers also manage both research and education in the laboratories and lectures for which they are responsible. However, when these LMSs are rolled out for an entire university, it can be difficult for individual faculty members to adequately assess and respond to the high costs associated with the infrastructure or to manage the costs. This study addresses this type of virtual private server and proposes a framework for a personal LMS that is able to manage a proprietary LMSs, without assuming an immediate large-scale rollout and while keeping the scope of the system restrained, such that the costs and labor for the system can be handled by an individual. As a result, while maintaining focus on the scale of e-learning in addition to operating the system accounting for cost and management aspects, I was able to avoid running the risks anticipated earlier on.
