    The experiment was carried out on the roof of our college building from May to June 1990 in order to study the effects of high- and low-heeled shoes on skin temperatures and clothing microclimate with six female young adults. Two types of shoes used in the experiment were the highheeled shoes (the height of the heel: 6.0cm, weight: 330g) and the low-heeled shoes (2.5cm, 320g) . The shoes materials were leather of which colour is white. In the experimental field, air temperature ranged from 23°C to 28°C, relative humidity from 55% to 65%, globe temperature from 28°C to 36°C and air velocity from 0.6 to 1.7m/sec. Thermophysiological parameters and clothing microclimate were continuously measured during the 90 min experimental period. The subjects walked for 20 min with a speed of andantino keeping steps with a metronome in the sunshine and took a rest for 10 min in the shade. These cycles were repeated three times. Major findings were summarized as follows: 1) Leg and instep skin temperatures were significantly lower mostly during the 90 min experimental period in the high-heeled shoes than in the low-heeled shoes. 2) Clothing microclimate temperature and humidity near frontal leg were significantly lower nearly half and mostly during the 90 min experimental period in the high-heeled shoes than in the low-heeled shoes, respectively. The present findings that there existed different skin temperatures in the leg and instep between two types of shoes were discussed from the viewpoint of different excitement level of sympathetic nervous system controlling cutaneous vasomotor activity caused by the high-heeled and low-heeled shoes.

    The effect of a washing net on detergency in a new flow type washing machine has been investigated in relation to mechanical energy input to cloths evaluated by calorimetry.
    The results are as follows:
    1) An assumption is made that the energy input to the cloths corresponds to the energy increase due to the addition of cloths into the washing system. For any given cloth load in kilograms per liter of bath volume, except very low cloth load, the energy increase per unit weight of the cloths in washing with the net is lower than that in washing without the net. The use of the net makes a distribution of cloths in the bath uneven, and so lowers apparent viscosity of the bath.
    2) Detergency depends on whether the net is used or not. For any given energy increase, lower detergency is obtained in washing with the net.

    A study has been made on the wearing consciousness on the styles of underwear and outerwear. More specifically, the relationship of the wearing consciousness has been examined between underwear and outerwear, wearing purposes of which are different from each other. The relationship has also been examined between wearing consciousness on underwear and outerwear, and socio-psychological characteristics.
    A questionnaire survey has been conducted to investigate the consciousness of women's college students, their mothers and women clerks. The results of the surveys are as follows:
    1) The factor analysis on the wearing consciousness of underwear and outerwear has revealed eight factors for each wear. Factors governing underwear are coordination, design, normality, functional property, custom, personal taste, economy and comfort. The factors governing outerwear are fashion, versatility, psychological comfort, self-expression, individuality, economy, outward appearance and material.
    For underwear, mothers tend to give their emphasis particularly on functional property, and college students on economy. For outerwear, on the contrary, students and women clerks tend to give their emphasis particularly to fashion to get a psychological stability through clothing. Mothers tend to give their emphasis on an functional aspects such as economy and material.
    2) A canonical correlation analysis has been made by using a factor score to evaluate the relationship among eight factors constituting the wearing consciousness on underwear and eight factors constituting the wearing consciousness on outerwear. The analytical results have shown that an economy of underwear correlates with an economy and a versatility of outerwear. An economy of underwear correlates most closely with factors of outerwear. In addition, the coordinative factor of underwear is related with four factors of outerwear, i.e., factors of self-expression, fashion, psychological stability and material. The factor of material consciousness correlates with factors of coordination and functional factors of underwear. Those who lay emphasis on material of outerwear have also close concern with underwear.
    3) An investigation of the relationship between wearing consciousness on underwear and outerwear and social psychological characteristics has shown that a significant correlation has been found between clothes of self-expression and those of curiosity. Furthermore, it has been revealed that those who have strong self-expression and curiosity are strong in fashion consciousness of underand outerwear.

    The ultraviolet rays shielding properties of various kinds of fabrics were investigated and their results are as follows;
    1) Aromatic polyester fibers and wool fibers have better shielding properties than other fibers.
    2) Fabrics made of staple fibers are better than those made of filament yarns, and textured filament yarns are better than flat yarns.
    3) Woven goods are better than knitted, and higher weight or higher density of fabrics are more capable of shielding from UV rays.
    4) Darker or deeper colored fabrics are more able to absorb UV rays, and so have better properties.

    In order to estimate the force necessary to detach solid particulate soils, polystyrene latex particles adhered to cellulose, acetate and polyester films were removed in the third model of the washing device, as has already been reported, and FH1/2, the force necessary to detach the soils, was estimated. The particle behavior was recorded on video tape, and analyzed by VTR system and personal computer. The results were compared with the results adhered to a glass substrate.
    The following insights were obtained:
    1) FH1/2 existed in order of: 1.Olμm<5.OOμm<15.0μm, and the order of polystyrene latex particles was: cellulose<glass<acetate<polyester.
    2) The particle behavior was ascertained to be of the two types, that have already been reported, namely A type removal and B type removal. The ratio of A type removal was affected by the hydrophilic property of substrates.
    3) The particle behavior of A type removal was ascertained to be of two types, namely A1 type removal and A2 type removal. As for the flow speed, the A1 type removal rate was higher than the A2 type removal rate. The moving speed of A1 type removal particles was faster than that of A2 type removal, that have already been reported as glass substrate. In 5.OOμm polystyrene latex particles, the ratio of A1 or A2 to A type removal, cellulose<glass<acetate<polyester, were affected by the hydrophilic property of substrates.

    Body image seems to be closely related to the interest in others and his (her) sensitiveness to the estimation by others. The qestionnaire was conducted on 272 male college students to investigate the relationship between body image and self-consciousness.
    The results were as follows:
    1. As for private self-estimation, the degree of the consciousness of bodily traits was low, but on the other hand, as for the consciousness of bodily traits of female, especially that of waist and bust, was rated high.
    2. The degree of bodily satisfaction was medium. Self-consciousness of face had positive correlation, and self-consciousness of the other bady parts had negative correlation with the degree of satisfaction.
    3. The degree of public self-consciousness was related to many of the bodily traits, but on the other hand the degree of private self-consciousness was not related to the body image.

    The effects of the concentration and pH of lactic acid, the time of immersion, the methods of squeezing, and the concentration of dye on cotton fabrics on the fading for C.I. Reactive Red 22 and a copper-complex azo dye were studied in detail to improve the testing methods for color fastness to light and perspiration. Since high water content gives more remarkable initial fading for dyes which undergo oxidative fading, centrifugal dehydration after the immersion is better used to get the reproducible results. The moderate pH conditions but severe ones give a small effect of pH on the fading. The optimum cencentration of sodium lactate was found to be 0.20 M, where the fading occurred in proportion to the time of exposure and the effect of dye concentration on the rating was small.
