ABSTRACT
Hypercubes and regular cross polytopes, which are generalizations in
higher dimensions, of the cube and the regular octahedron of the third
dimension, are not only useful, for example, in the analysis of the
partition of Euclidean regions in applications, but also interesting on
their own mathematical right. The present note discusses some properties
of their degenerate cases in the first and the zeroth dimensions defined
through analytical continuations, using Gamma functions and
differentiations as tools for their analysis.
ABSTRACT
The number of co-authors for Japanese scholarly papers tends to be
larger than that for foreign papers, as is occasionally indicated. This
should be attributed to the way of conducting research, and to the
cultural and social climate in Japan.
The present paper consists of two parts: a report of the results
obtained in a preliminary survey on the number of co-authors in
abstracting databases; and an essay on Japanese environment for research
activities that brings about heavily co-authored papers. The preliminary
survey has indeed indicated that Japanese papers have more co-authors
than USA papers. However, the variations among fields of research are
expected to be substantial, and consideration on designing the complete
statistical future survey is discussed.
In the second part, characteristics and creativity of co-authored papers,
and editorial policy of academic journals, of Japan are compared to those
of Western countries through the actual examples. Although advanced
electronic media is expected to make joint research be conducted more
easily, it may also make the publication more individualized to reflect
personal contribution of every researcher.
ABSTRACT
The diagnositc process of physitians has been studied from very early
stage of artificiall intelligence research. It seems that physicians
perform information acquisition from patients and diagnostic hypothesis
generation simultaneously at the first clinical encounter. The authors
classify the diagnostic prosess for a first-encounter-patient into seven
basic tasks performed simultaneously. According to this model, the author
also proposed a framework for parallel prosessing of these tasks on a
computer.
ABSTRACT
A new method is proposed for identification of document records in
bibliographic databases. In databases, documents are often specified
in a format that can be found, for example, in reference list. On the
other hand, in information retrieval system it is required to retrieve
the most likely record based on insufficient information concerning a
specific document given by a user.
In this paper, an algorithm to cope with input error, abbriviation and
special notation and a method to estimate likelihood of documents are
proposed.
A core system was implemented to demonstrate these algorithms with
syntax analysis software which operates in accordance with this core
system. A evaluation was also done, using actual bibliographic records
from NACSIS databases and a high rate of identification was achieved
with the proposed method.
ABSTRACT
Oohashi et al. have experimentally shown that inaudible high-frequency
components in music nevertheless constitute a contributory factor to the
pleasure in listening. Based on their findings and some certain facts
from auditory physiology and brain science, we critically examine some
aspects of musical qualities of analog LP and digital CD records. We
then suggest some future research topics and mention some relevant
issues of ethnic and cultural heritage.
ABSTRACT
Recent development of chemical information databases, in particular,
those of chemical structure and fact databases are discussed. There has
been major development in the area of chemical structure search systems,
chemical reaction databases, generic structure databases, physical
properties data and spectral databases, and biological databases.
Database activities in Japan are briefly summarized.

ABSTRACT
Field surveys on Japanese collections in Korea, Europe and US were
conducted to identify the problems as the information sources on
contemporary Japanese studies.
The current survey of 9 Chinese institutions was carried out with three
points in mind: 1) comparisons with the results of previous surveys, 2)
feasibility of union catalogs for Japanese materials, and 3) review of
supporting elements such as materials and librarians inseparable from
Chinese Japanology. Consequently, characteristics of Chinese Japanology
including 1) concerted interest in Japan's modernization, 2) direct
access to corresponding Japanese scholarly community, and 3) prominence
of Japanese language as the source materials were identified. China has
both favorable and unfavorable conditions for construction and
maintenance of union catalogs of Chinese materials, whereas, for
Japanese materials, some plans are going to be formulated.
International cooperations on union catalog compilation may be feasible.
The validity of viewpoint to regard Chinese Japanology as inseparable
from its supporting elements may be confirmed by the nature of Japanese
studies in China.
ABSTRACT
"Feasibility Study on International Exchange of East Asian Databases''
was a FYs 1989-1991 three-year international research project of the
National Center for Science Information Systems (NACSIS) of Japan, which
is one of the Inter-University Research Institutes under the Ministry of
Education, Science and Culture (MESC), supported by the grant-in-aid of
MESC, as the first phase of the study to stimulate international
exchange of scholarly information available in non-alphabetic scripts,
in particular, Kanzi (Kanji) in China, Japan and Korea (CJK). The
present note describes the objectives, background, methodology, and
achievements of the study, and suggests future tasks to be pursued in
the second phase of the study.
