Technical report of IEICE. SS ( The Institute of Electronics, Information and Communication Engineers ) 104 ( 570 ) 7 - 12 2005.01

The purpose of this research is supporting the Web application development which utilized the power of expression on a client side. Therefore, we propose and develop a new Web application framework. Struts is adopted on the server side as the base of Web application development. On the other hand, Flash is adopted on the client side in order to realize abundant power of expression and operation in a user interface. In this paper, first, described that we propose and implementation experiment the combination technique of Struts and Flash. Next, we propose and build the Web application framework which utilized Flash. Finally, the usefulness of the Web application framework is examined.

TANI YOSHITO, MITSUDA NARUKI, AJISAKA TSUNEO （Part： Corresponding author )

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 144 ( 30 ) 131 - 138 2004.03

Web sites on the Internet has been increasingly provided and used for wide variety of application. They are implemented by using various techniques such as markup, scripting, programming, and form specifying languages. It makes the web application software ill-formed and difficult to maintain. This paper presents a method for implementing the front-end of a web application using XSLT. As it is a homogeneous construction, modular approach to development and maintenance is possible for web software of high quality. The proposed method is implemented as a framework, that is, a collection of servlet classes to be the components of a target web software of which overall logic is written with XSLT. A case study using the framework is shown in this paper, with discussing a particular information architecture within the framework.

Data Schema Extraction from XML-DTD Based on Entity Collection Patterns

TANI Yoshito, MITSUDA Naruki, AJISAKA Tsuneo （Part： Corresponding author )

Technical report of IEICE. SS 103 ( 102 ) 25 - 30 2003.05

Information systems using XML as backend data are promising in interoperabilty, extendability, etc. A major issue in developing such systems is constructing efficient data schema for the system's database engine. A straightforward transformation from a DTD to DB schema would not work. This paper proposes a method of generating schema appropriate for data base functionality from XML-DTD. The method is based on an idea of the entity collection pattern, that enables to make resultant schema reusable. While the core of the method is automatic, optional design considerations are also discussed.

UEHARA Tetsutaro, SAITO Shoichi, MITSUDA Naruki, IZUMI Yutaka, TSUMAKI Yusuke, NISHIYAMA Yasufumi, KUNIEDA Yoshitoshi

情報処理学会研究報告インターネットと運用技術（IOT） ( Information Processing Society of Japan (IPSJ) ) 26 ( 82 ) 37 - 42 2002.08

When offering wireless LAN hotspots for free of charge, the user-authentication system may often become the important issue. Without any user-authentication mechanism, the hotspot could be a fat target as the entrance of anonymous internetworking for crackers, but if we force the users to be registered in advance it is too cumbersome and causes the decrease of them. In this paper we propose a simple user-authentication system using mobile phones with e-mail and browsing services to make the authentication easy for the users and also to reduce the administration cost of the hotspot.

Structured Scenario Description and Deriving Operation Models for Use-case Based Design

TANI YOSHITO, MITSUDA NARUKI, AJISAKA TSUNEO （Part： Corresponding author )

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 127 ( 46 ) 47 - 54 2000.05

Software systems design should get started with requirements description written down from the endusers' viewpoint such as use-cases. The use-case model is however not enough utilzed for detailed design in real processes. This paper aims at effective use of use-case models by deriving operation models from them. In order to derive operation models automatically, it is firstly needed to make use-case scenarios structured, and then the deriving rules are defined. An experimental tool is implemented to evaluate the structuring methods and deriving rules. According to some experiments on an example system description, several sorts of information are found additionally required to derive complete operation models.

Analyzing Changes in Design Information for Supporting Software Evolution using Repository Framework

SAWADA Atsushi, MITSUDA Naruki, AJISAKA Tsuneo

Technical report of IEICE. SS ( The Institute of Electronics, Information and Communication Engineers ) 99 ( 424 ) 7 - 14 1999.11

We are aiming at developing a software environment which can provide systematic support to designers who are required to manage evolving software. In this paper, we claim the necessity of a middleware which can handle software product in a semantically modularized manner. We adopt our repository system named Prism (Portable Repository Interfaces of Semantic Modularity) as the underlying middleware, and analyze changes in design information using Prism's schema language. Based on the analysis, we elaborate how we realize tools which can support schema changes on the top of Prism.

An User Interface Design Method Focusing Operation Information

MITSUDA Naruki, SAWADA Atsushi, AJISAKA Tsuneo

Technical report of IEICE. SS ( The Institute of Electronics, Information and Communication Engineers ) 99 ( 424 ) 23 - 30 1999.11

In recent development of application software, developers make many efforts to design and implement user interfaces. Our research is aiming at reducing such efforts with middleware services. We propose a design method of user interfaces in this paper. The method focuses a scenario of user operation. A scenario is derived from usecase description which defines user requirements of application software. There are mapping rules from elements of usecase to a state transition model which represents a scenario of user operation.

Towards a Design of Structural Constraints Management for Software Repositories

BAN Keita, SAWADA Atsushi, MITSUDA Naruki, AJISAKA Tsuneo

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 107 ( 6 ) 65 - 72 1996.01

Data integration facilities in CASE environments are provided by software repositories, which involve all aspects of software subject information with various kinds of constraints. For consistent management of them, structural and semantic constraints should be layered in a repository apart from tool programs. In this paper, we examine several limitations on the E-R model to find a model that represents pure structural constraints and therefore that is independently plu-gable with semantic constraints. Those alternative E-R models are compared using some quantitative metrics, giving a guide for a universal structural management in software repositories.

Design of User Interfaces for Process Integration

MITSUDA Naruki, AJISAKA Tsuneo, MATSUMOTO Yoshihiro

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 102 ( 11 ) 177 - 180 1995.01

This paper describes a design strategy for user interfaces which provide process integration services in a CASE environment. This strategy is based on a classification of information used by user interfaces. At the physical level, the UI designer models structures of presentation areas in a bitmap window and constraints among them. At the logical level, he makes another model which shows a process of input and output of his tool. This model includes events, states, and the relation of cause and effect on them. The UI library should provide a mapping mechanism between tow levels.

Data Access Programs Derived from PCTE Schemas

Mitsuda Naruki, Sawada Atsushi, Ajisaka Tsuneo, Matsumoto Yoshihiro

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 1994 ( 6 ) 17 - 24 1994.01

PCTE uses extended ERA models called SDSs (Schema Definition Sets) to define data models used by tools. An SDS very much reflects logic of tools when it is designed specially for them. In this paper, we propose the system which automatically generates the typical data access programs from SDSs. The C++ classes are derived from the object types, and the C++ methods are derived from the link types or the attribute types which are applied to the object types. A small example shows how this system generates the data access programs. We also discuss the extension of the system which enables the system to work with the future PCTE.

Defining an action by examples in CBAD

笹倉万里子, 岩間憲三, 満田成紀

全国大会講演論文集 45 ( 0 ) 239 - 240 1992.09

われわれが研究開発中のCBADはアニメーションに登場する対象(actor)とその動作をあらかじめ定義しておき,それらの対象に対する動作要求を継ぐことでアニメーションを作成するシステムである.CBADの特徴はものとものとの関係をconstraintで表わすことができるということである.これにより,ユーザはプログラミングよりも一歩抽象度の高いレベルでアニメーションを記述することができる.CBADに関しては第43回大会で発表した.今回は,CBADにおけるactorの定義,特にその中のactionの定義について述べる.アニメーションを作る時にユーザが独自のactionを定義する必要があることもある.独自のactorには表示されるactorのイメージを新たに登録したりすることも必要であるし,また,独自のactorを作成する必要に迫られることがある.actionの定義はactorの動きを定義することであり,一般的にはプログラミングが必要である.しかし,われわれはプログラマでないユーザにも使えるようにするために動き方を示す何枚かの図をユーザに入力してもらうことによってactionを定義する方法を提案する.例題によりものの指定を行うことは特にノンプログラマにとって有効であると考えられている.ユーザインターフェース関係で例題による指定を実現したものとしてはユーザインタフェース構築に例題による入力を用いたperidotとグラフィックエディタに例題による入力を用いたmetamouseが有名である.
