    In Japan, there has recently been an increasing interest in health, home care and welfare, as we enter into a society occupied by more and more elderly people and a smaller number of younger citizens. The Japanese government and the administrative divisions of Japan, including Tokyo, Hokkaido, Osaka, Kyoto and all the prefectures, have been adopting many kinds of health and welfare policies. As one such policy, the Ministry of Health, Labor and Welfare designated an instrument for blind people and elderly people as a "daily life tool" in April 2003. This instrument translates information printed on paper to voice reading. The Ministry's policy and the associated budget will enable blind people to purchase the instrument with very little cost. Our company developed this instrument, called "SPEECHIO," as well as the new software that converts text to two-dimensional symbol named "SP-CODE." The SPEECHIO reads SP-CODE and changes text into voice reading automatically. We believe this new barrier-free communication system will greatly help blind people and old-aged people who have difficulties in reading small prints. In this article, I describe this system and our ongoing and future activities with the system.

    The rapid advances in digital technologies and networks have radically altered and improved the ways that data can be produced and used in science. The public domain information is defined as sources and types of data and information whose uses are not restricted by intellectual property or other statutory regimes and that are accordingly available to the public for use without authorization or restriction. It is increasing the pressure between the need of science for the free flows of data and information, and the considerations of the intellectual property rights with regards to the same data and information under the digital network environment. It is discussed in the case of the Global Biodiversity Information as the one of academic data and databases how to implicate the intellectual property rights on the databases. The EC Database Directive 1996 is created by a two-tier structure of intellectual property protection for original databases through copyright, and a new sui generis right for other unoriginal databases. In the United States, the bill named the Database and Collections of Information Misappropriation Act of 2003 (H.R.3261) is now in the process of legislation on the Congress. Where access to information is at issue, it would be necessary to introduce the new model of database rights as balanced with the free flows of academic data and databases in Japan.

    Classification of research fields for the Grants-in-Aid application has been changed a great deal since 2003 fiscal year. Changes in the interdisciplinary and new area are marked especially. It is interesting to find out where the usual research fields are moved to in the new classification. In this study, we focus on Information Science fields which were extended from the three to 11 research fields, and investigate which new research fields have strong relationship with and how they are located in the usual three Information Science fields by making use of those continuing adoption research started before 2002 and by analyzing keywords of research themes as well.

    In recent years, an information technology has been progressed. And our country is establishing to a highly information-oriented society. Then, the support system to information practical use is aimed to build for personal-use. However, in a meaning of making good use of material information, there are still many inadequate systems. Then, this paper considers the development technique and the state of the support system which surround material information by making into an example the database application system which supports archaeological data research.

     e-ラーニングでは教育の効率向上を目指した遠隔授業システムやWBT(Web Based Training)などが先行して実用化された。しかしこれらのシステムでは教育者と学習者とのインタラクションが低下し、教育の質を改善が図れるとは言いがたい。これに対して最近、学習者の進捗や理解状態をリアルタイムで教育者にフィードバックし、教育者の教育活動を支援して教育の質的改善を図るシステムが提案された。その一つは、標準的な知識提示はWBTで自動的に行いつつ学習者の行き詰まりや理解状態を示す情報を教育者に提示しそれに基づいて教育者を個々の学習者の教育に専念させるものである。もう一つは大人数授業で学習者全員の演習問題の進捗を教育者に提示し、教育者に授業の運営判断を行わせるものである。またe-ラーニングで蓄積した教育ロブを分析し、教育方法の改善に資する事も有効である。この分野は現在まだ萌芽の段階だが期待は大きい。

     A method in an innovation and effects caused by it are described in patent document. We regard the method-caused effect as causal relationship and consider it available to construct creativity support system, therefore we have extracted some causal relationships. In the future, we try integrating hierarchical relationships into causal relationships to construct funcion of analogical reasoning. Therefore, in this work, we extracted hierarchical relationships from patent documents, especially selecting medical field as extracting target.

    Free term search is one of the most effective ways to search text data. However, it is difficult to search for specialized texts such as historical official records, in which there are many specialized terms different from currently used. It is also difficult to compile a thesaurus, which covers all diversified historical terms. This paper proposes one solution using a specialized dictionary compiled for the Japan Center for Asian Historical Records.

     1990年代以降、複雑なデータ構造をもつ様々な対象に対する情報視覚化の研究が盛んに行われるようになった。 EDR電子辞書やNTT日本語語彙体系のような階層構造を有する大規模用語知識ベースを対象として、単一円錐モデルに基づく仮想3次元表示プログラムをJAVA3Dを用いて実装した。さらに表示用語総数に対する実行時間の計測を行った。描画対象オブジェクトの総数をnとすると、描画処理そのものは計測結果からO(n^3)となることが判明した。プログラム言語の制約、仮想3次元描画対象としての用語知識ベースの特性から、高速化の可能性について議論した。

     本稿はUNIXワークステーションのアカウンティング情報を用いて利用者のネットワーク構造を抽出する手法について述べ,得られた大学生計算機利用者の人間関係の特性について考察する/情報システムというように「人」が主役の場では人の関係が重要である.例えば,初対面の人と会った場合には,自分とその人とのつながりや,趣味,共通の知人などが分かれば,コミュニケーションがよりスムーズに進むと考えられる.このように情報システム利用者の社会ネットワークは非常に重要な情報のひとつであると考えられるが,これまで情報支援の研究において着目されることは少なかった.これは利用者のネットワーク構造を情報システムが獲得することが困難であるめであると考えらえる.本稿の手法を用いた結果,大学生の人間関係は任意の二者間の平均経路長が2.95人であるスモールワールドネットワークの特徴を持つことがわかった.

     The availability of complete genomic sequence data allows one to develop new methods of reconstructing phylogenetic trees. A simple method of reconstructing branching orders based on gene transposition (or lateral transfer) is presented. It is shown that specific gene arrangements on four different genomes could determine a branching order. A computer search for such gene arrangements was carried out against gene order data of the completely sequenced Gram-positive bacteria, and the results will be discussed.

    We developed a remote aged care system for Hanazono village which is one of the typical underpopulated villages in Japan. In many of such depopulated villages, there is the problem that the number of visiting nurses who provide aged care services is not enough. As a result, visiting nurses can visit aged people not so often (it might be once a week or so), and hence aged people is easy to lose their health. To improve this situation, our system helps visiting nurses get hold of the health condition of aged people by showing the information of their daily health condition which is input everyday by aged people at their own houses. Here, to make a easy input operation even for aged people, we use L-mode terminals at each house and design easy-to-operate Web pages which are accessed by the terminal. We further performed a test operation of our system in Hanazono village and confirmed the effectiveness of our system.

     We have presented the concept and planning of the project ICJS: International Collaboration for Japanese literary Studies, in the 10th annual conference of JSIK held on 2002 in Tokyo. The project has been started from 2001 as the five-years program, founded by the Grant-in-Aid Scientific Research (S). In this presentation we will generally report on the interim result for three years, and particularly focus on the new collaboration system through feasibility experiments.
     We are now in feasibility studies, an example of simultaneous searching using a Dublin Core meta-database system is shown as follows. The six databases are currently connected to the collaboration system at the NIJL: the microfilm resource directory (a catalog of the microfilm held at the Institute), the old Japanese book directory (a catalog of the manuscripts held at the Institute), the thesis directory (a directory of theses related to Japanese literary research), the historical material location directory (a directory of the places historical resources are held at the Institute), the image database (an image database of materials held at the Institute), and the moving picture database (performing arts video data).
     Then, we have been making arrangements expand and develop enlarge the system to Inter-university or Institute common collaboration system. For example, we will construct among the Institute such as National Museum of Japanese History, International Research Center for Japanese Studies, National Museum of Ethnology, The Historiographical Institute University of Tokyo, Osaka City University and Kyoto University. At the next stage we will be connecting to Italy, France, U.K. U.S., etc.
