In authors’ previous papers the essential meaning of
the ubiquitous system has been presented as it is in the
idea that the functions that the today’s ordinary and
healthy society lives have lost should be recovered as
before or supported up to their ordinary average levels.
On the other hand the authors have discussed the
design technique and direction of the expanded EMR
(Electric or Electronic Medical Record), and at same
time, in parallel, have developed the communication
system in which the “YUBITSUKIYI (which is the
name of communication tool for blind deaf persons.
See Fig.3)” system is included. Therefore the authors
have proposed that the Life Support System to be
developed from the expanded EMR system should be
restructured and synthesized and used on the basis of
the essential meaning of the ubiquitous concept. And
by using this Life Support System the lost functions are
able to be recovered as before and supported up to the
ordinary average levels. Now when the authors treat
the dementia situation, by considering an ontology of
the situation it is treated as a kind of handicapped
situation from the point of view that the dementia
situation is the situation in which the function to be
gained before has been lost. As a result it is able to be
estimated that the Life Support System can be used to
find and support the dementia situation, especially to
find and support the early dementia situation not only
of the blind deaf persons, but also of the ordinary
persons. And also it is able to be estimated that the
dementia situation can be treated quantitatively by this
Life Support System through the communication
process and the consideration of information
processing. From the point of views of communication
process and information processing the authors have
already presented the new information contents able to
be applied to the dementia situation, at present it is
becoming more clear that the new concepts are able to
be applied to a kind of human error situation of the
ordinary people. On such new information contents at
same time the authors have studied these concepts in
parallel for three directions as main directions. The
first of them is the direction that such information
concepts themselves must be newly considered from
the entirely different view point, and the second of
them is the direction that such concepts should be
studied on the philosophical view point (for example,
Peirce’s semiotics and its interpretant etc.), and the
third of them is the direction that these concepts are
treated on the basis of Fuzzy concepts and expanded
from the ordinary Shannon’s information theory by the
use of Fuzzy system’s idea. In this paper the discussion
of the third one is developed over the discussion which
was already described in the authors’ previous papers.
From the third one of discussing direction authors have
already studied the new information contents on the
basis of Fuzzy concepts and have gained some
important ideas and relations among the information
structures and the meaning and concepts of such
factors. At this time, expanding such results it is
described that the Fuzzy model expanded from the
model of ordinary Markov’s information source is
introduced into the object of Fuzzy set model and some
relations of the Fuzzy information system derived from
the Markov’s information source are described.
