    E-Classroom Project is a project to create an advanced learning community beyond usual curricula on the Internet in cooperation with junior and senior high school students, researchers and teachers. We adopted “Net-Commons” as the platform of e-Classroom; Net-Commons is information sharing portal system which was developed by Noriko Arai and NTT-Data Pocket Cooperation Ltd. “Net-Commons” provides online concerted learning environment which allows both administrators and common users to utilize digital contents available on the Internet. The main communication tool provided by Net-Commons is a user-friendly bulletin board system; users can post their text messages combining with images and files. A flexible page layout function of “Net-Commons” easily actualizes the optimum page layout which fits needs of the community on the Web. Observing the advances of learners, the teaching staffs flexibly change the page layout and provide necessary learning materials timely. Consequently, teaching staffs pursue the best blend of various e-learning tools without paying any additional costs. Learners together with teaching staffs build learning community on the Internet, and the data shows that the more learners attend e-Classroom, they improved logical way of thinking and presentation, and they attained better online communication methodology.

    The author tried to clarify bibliometrical characteristics of Japanese university articles published on an electronic journal system. The basic data for this research was collected in July and August, 2003. Firstly, specified top 30 universities for 2003 in article publishing, and then extracted bibliographical information including number of articles and coauthoring in 1997 and 2003 from the basic data set. Number of citation those articles received was investigated about 11,921 articles published in 1997 as well. This study shows that publication of university articles tends to concentrate on limited journal titles. Although coauthoring ratio with foreign organizations increased by 4 points from 1997 to 2003, but the ratio with industry was unchanged. As for 1997, 1/3 or more of the university articles were cited 0 times.

    To find out promising intermediates in fine chemical area the authors introduces exploring method using search results of Chemical Abstracts. All the extracted intermediates are compounds that are cited in CA and registered assigned CAS Registry Number. Among those intermediates which can be used in synthesis of investigative new drugs, a growing business field in the market, the authors particularly extracted intermediates which are available in plural number of investigative drugs (so-called common intermediates). It is said to be significant factor in intermediate business that those compounds can be applied in diversified uses. It is found that the common intermediates covered in this study are highly expected to be used not only in investigative drugs for a diversity of diseases but also in investigative drugs a number of companies deal with in the new drug development.

    In order to see how user-friendly a digital library is, the author takes a navigation as a viewpoint. A digital library has no librarians in it. Instead, navigation has such a role that it guides the visitors to the location inside the site or materials they want, or show them around inside the site. This article considers what a desirable navigation is by showing three digital library cases. It founds the two requisites of the navigation, 1) to enable visitors at any location of the site to grasp the whole information and organization of the digital library, and 2) to enable the visitors at any location of the site to get idea for their research or searching. The author find it necessary that the contents are hierarchically organized, and such relationships as subordinate/coordinate classes, related classes are set among contents.

    The protection of digital content in connection with acts of reproduction, public transmission and making transmittable is provided for under the Copyright Law, and digital content protection technologies, such as copy control and access control technologies, are protected under both the Copyright Law and the Unfair Competition Prevention Law. Further, a certain means for the restraint of illegal digital content distribution is available under the Provider Liability Law. But the fact is that, the total volume of “reproduction for private use” of digital content by way of downloading has become so large with the mass proliferation of computers coupled with the Internet and enabling P2P software, etc. that the situation is getting beyond the reach of existing laws, which only regulate acts of public transmission. Lost profits of right holders are becoming increasingly difficult to ignore. In all, it is imperative that legislative measures be taken.
