The purpose of this study was to investigate the changes of self-evaluation and emotion due to gap between social and group norms. Subjects were the university students who had the norm to wear a suit in job hunting scenes. In this study, the subjects were asked to imagine themselves in one of the four scenes of job hunting wearing either a suit or casual wear. The group of wearing casual had lower self-evaluation and higher anxious than the group of wearing a suit. On the other hand, they had low self-evaluation and high anxious due to deviation from group norm when they had a strong need for conformity and/or tendency of an over adaptation to the group of people who had a social clothing norm. As a result, it is considered that a negative change may happen when they deviate from group norms even if they fellow social norms.

The effect of the air flow, parallel to the home-made fabrics with various yarn densities, on the water vapor transfer coefficient (WVTC) has been investigated by simulated technique of the JIS ‘Water Method'. The WVTC value increased for the higher flow rate and decreased for the larger yarn density.

The water vapor permeation coefficient of the fabric (WVPCF), evaluated from the difference of the water vapor transfer resistances with and without the fabric, was linearly dependent on the square of the air flow rate. The tangent of the dependence, expressing the degree of the effect of the air flow rate on WVPCF, increased linearly for the porosity of the fabric higher than 19%, and was ignored for the lower. An experimental formula estimating the WVPCF from the parameters, the porosity of the fabric and the air flow rate, has been obtained for the fabrics.

The technique to dye fibers green by using plant dyes, traditionally pre-mordanted by iron acetate, should be considered from the viewpoint of deepness and light-fastness of the hue. We have therefore investigated the use of vanadium as an alternative mordanting material, as it represents a transition element that is in the same period as iron. Wool fibers were dyed using tetravalent vanadium solutions, with solutions of 5 ×10^-3 mol/L vanadyl sulfate found to produce a deep green color and light fastness with a natural plant dye yashabushi 50 % owf. Electron spin resonance spectrum of vanadium on the wool was identified as signal associated with complex of oxovanadium remained in wool. It was shown that the wool dyed green by vanadium has low irritation to skin and the vanadium is effective as the new mordant which could reduce environmental load．
