Abstract. These days, aging of population is becoming serious problem more
and more. Due to this aging, problems of suffering of unbearable pains of
lonely single living old people with inconvenient movement in loneliness are
occurring. Existing studies have focused only on the management of physical
health of the aged but in this paper, on the contrary, psychological issues of the
aged, in particular, lonely situation of the aged is reviewed. For this, system that
can recognize lonely situation of the aged automatically and solve loneliness by
monitoring behaviors of the aged is necessary. However, it is impossible to
quantify lonely situation as there are lots of differences per each individual. In
order to solve this problem, flexibility of system is required in adding or
revising situations in which each individual feels loneliness. Therefore, in this
paper, methods to ratiocinate lonely situation using rule are suggested. This
method has advantage of no need to revise internal code as only rule can be
modified when situation, in which the aged feels loneliness, is added or revised.
In this thesis, system ratiocinating loneliness of the aged was designed and
realized using RFID tag and reader and matters to be improved in the future are
pointed out.
Keywords: Loneliness, RFID, Elderly People, Rule.
1 Introduction
These days, aging of population is becoming serious more and more. Because of this,
a variety of social issues are generated and among them, the most representative issue
is the health management of the aged. However, since most studies focus only on
physical health of the aged, other factors of the aged such as emotion are not
receiving attention comparatively. Cases of old people with inconvenient movement
or lonely single living old people have not only physical pains but also mental pains
caused by loneliness are also unbearable pains. To solve this, service, that can find out
lonely situation of the aged and to alleviate loneliness of the aged, is necessary.
Therefore, system, which can recognize and automatically solve lonely situation by
Monitoring behaviors of the aged, is necessary.
In this study, RFID tags were attached to objects such as home appliances
(refrigerator, water purifier, gas range, and etc.), furniture (chair, bed, sofa, and etc.),
