    Evaporative heat transfer properties through fabrics were evaluated with a sweating hot cylinder which was designed so as to maintain both temperature and wet condition of the skin constant for more than two hours. Samples used were twelve kinds of typical kimono fabrics. The skin surface of sweating cylinder was controlled at four different wet conditions. A (skin wettedness, w=1.0), B (w=0.54), C (w=0.16), and D (w=0.82) . The results obtained were : 1. Evaporative heat transfer through fabrics for summer casual use were the highest of all fabrics in any wet conditions, and those through fabrics for autumn and winter use were the lowest. Polyester leno, in spite of for summer use, showed low values under the conditions B and C. 2. Evaporative heat resistances of each fabric was little affected by wet conditions of the skin, but the evaporative efficiency was much affected by it due to the water absorption properties of the fabrics.

    Evaporative heat transfer properties through fabrics were evaluated using a sweating hot cylinder which was developed in the previous study. Samples used were twelve kinds of representative kimono fabrics, each of which was wrapped around the cylinder with a 4mm air layer between the fabric and the cylinder. The conditions of skin wettedness of the cylinder were controlled at 1.00 (A), 0.55 (B), 0.17 (C) and 0.83 (D) .
    1. Evaporative Heat transfer (He) through the fabrics was decreased 30-75% by putting a 4mm air layer between the fabric and the cylinder. The fabrics which showed large He were silk-plafain gauze and silk-leno, both of high air permeability, and those which showed small He were linen, wool and cotton yukata-ji made of span yarn.
    2. Evaporative heat resistances (Re) of the fabrics was effectively estimated by the multiple regression equations which were obtained for every condition of skin wettedness.
    3. Evaporative efficiency (EE) of eath fabric ranged from 0.4 to 1.2, which was much lower than in the case where no air layer under the fabric was present.
    4. As a result of principal component analysis, evaporative heat resistance, air permeability and water and moisture absorption properties were extracted as the three largest components.

    The purpose of this study was to compose a three-dimensional computer graphics model of human body parts, called joint divisions, using truncated ellipse cones. Truncated ellipse cones are more suitable than polyhedrons for approximating human body shapes. Thus, a new effective vector expression Φ with lists of six components was used for these joint divisions. Using the Φ joint division vector, the graphics forms fitting these joint divisions were generated by vector expressions S, the outside surface generating function. Furthermore, Gen (Φ), joint division generating functions, which compose several joint division vectors, were used to make lager human body divisions. By allowing these joint division vectors to be manipulated by computer, more complex human body divisions could be represented.
