    It is hard for elderly women to fasten or to undo closures of the open part of blouses because careful hand works are required. In order to assess the ability of movement of fastening and undoing various closures such as button, snap hook, string, velcro fastening and sliding fastener, wearing test was carried out. Basic design cotton blouses with different closures were prepared. Test subjects were five elderly women and eleven female college students. The all wore five kinds of blouse samples. The ability of movement in fastening and undoing blouses was examined in the test. We measured the lap time of their achieving the work for wearing and removing while observing the wearer's movement. After each wearing test, the questionnaire survey has been conducted as to the preference of subjects for blouses. Results for elderly women were compared with those of young female students. Significant factors to affect elderly women's movement were derived. The results provided the important information to design the comfortable blouses for elderly people to live clothing lives independently.

    Some tri-valued random patterns, for example tricolor of Red, Green and Blue, were generated using opposite-Sugeno integral filter. In the process of converting images, a conversion function for normalization was inserted between two steps of the filterings applied to independently Red, Green and Blue.
    To make tri-valued patterns from multicolored patterns, they were firstly transformed into gray images. Secondly, the 3-tile thresholding was applied to segment the image into three regions. As the result, three kinds of binary images, and their three kinds of rotated binary images were obtained.
    New type of symmetry was defined in addition reversal symmetry and rotational symmetry as defined in the previous paper. It was named as region reversal symmetry, was defined by equality in the index of contrast calculated from the first three kinds of binary images.
    Ranking of tri-valued geometric patterns (14), random patterns (15) and collected camouflage patterns (135) was synthetically carried out in the evaluation of symmetry goodness using the three types of symmetry.
    Ten ones out of the fifteen tri-valued random patterns were ranked in the twenty bests in the synthetic evaluation among all 164 patterns.
