We describe a regional safety information sharing system based on CMS and online map system. The system is characterized by extending the functional capability of XOOPS, which is a type of CMS, with online map system. It accumulates local knowledge through mapping of safety information by local residents. To evaluate it by a field experiment, we introduced it into Higashi ward in City of Nagoya. As the result of the experiment, we found that our proposed system was effective for sharing regional safety information among the community. [ABSTRACT FROM AUTHOR]

In this study, we build a knowledge database that consists of topics planetarium curators have about astronomy and the stars. We suggest that the database should have a structure based on constellations and that mirrors the basic way in which humans perceive the night sky. Furthermore, we developed a web system for astronomy education using Ajax. The web system's interface is based on the planisphere, which is most basic tool for finding stars. [ABSTRACT FROM AUTHOR]

In this paper, we propose a Web-based system to promote public safety and security that uses grassroots information to prevent and solve crime. The feature of our system is that it gathers and formalizes information related to crime or suspicious activities. The system provides useful information by arranging it with time and geographical attributes. As a result, people can find out about crime and suspicious happenings in their local area. Using this system enables people to share their experience and knowledge before crime actually occurs. This can lead to strategies for self-defense against ever-evolving criminal techniques. Keywords: Crime Prevention, Local Community, CMS, Information Sharing. [ABSTRACT FROM AUTHOR]

In the field of edutainment, it is very important to produce Web3D works efficiently, and to be able to visualize or interactively experience obscure heritage architectures and historical events. In this article, we describe 3Dblog technology, which we have proposed and developed. In addition, we explain a virtual system that we constructed by applying the proposed 3Dblog technology. In addition to being a useful and enjoyable learning tool, 3Dblog not only enables non-professional users to construct objects easily, it also allows both object constructors and users to easily participate in the construction of a virtual environment collaboratively. This brings forth new possibilities in experiencing virtual heritage ... [ABSTRACT FROM AUTHOR]

This research paper aims to develop a simple Web mail system for senior citizens to make the best use of their empirical knowledge as social properties, which is one plan of an informationization promotion project by industrial-government-academic cooperation begun in 2004. A simple Web mail system is made for trial purposes as a concrete example for senior citizens based on their needs, and an indicator of grappling with the current state in development and future problems is described.
