目的 2本の円管をT形に結合した合流路を用いて, 三次元的にニュートン流体と粘弾性流体の流れを可視化して観察し, さらに粘弾性流体とニュートン流体の流れを比較してその特徴について検討する.結果 粘弾性流動においては, 平行平板管路を用いたT形流路の場合と同様, 合流部の凸状角部の上流側に循環二次流れが発生する.循環二次流れの生長による合流部付近の流線長さの変化は, 流れの弾性的効果を現わすワイセンベルグ数で整理すると, 管路の絞り比や流体の高分子濃度にかかわらずほぼ1本の曲線に載る.これらのことから循環二次流れの発生及び生長には流体の弾性的性質が大きく寄与していることがわかった.

The wear sensations of wet fabrics have been examined by the wear trials. Four arm covers consisting of cotton, wool, polyester and acrylics fibers are used as specimens. The results are summarized asfollows :
(1) This wear trials have been examined under three ambient conditions, i. e., 10°C/65% R.H., 20°C/65% R.H. and 30°C/65% R.H. The most significant difference of the wear sensations are found between the dry and the wet fabric at an amebient temperature of 20°C. The subjective estimation of coolness is obtained at an ambient temperature of10°C. The subjective estimation of the sence of touch and humidity is obtained at an ambient temperature of 30°C.
(2) The features of various kinds of wet fabrics are found by this wear trials. It is found that a wet wool fabric is better than other textile fabrics in the subjective estimation of warmness and humidity.

Two surveys were conducted to investigate possible relationships between clothing behaviors and socio-psychological characteristics. The survey (I) and (II) were undertaken to examine relationship between fashion-oriented behaviors and socio-psychological characteristics of 78 high school girls, and relationship between aesthetic-oriented behaviors in dress and the characteristics of 141 collegewomen respectively.
Instruments used in data collection were, measure consisting of 10 fashion-oriented variables, . measure of 18 aesthetic-oriented variables, and Suzuki's socio psychological characteristic measure, which is consisted of 12 scales, namely, self-actualization, inferiority feeling, self-display, deorganization, curiosity, information seeking, feminity, sensitivity, conformity, physical strength, intellectual interest, and delinquency. Coefficients of reliability for the fashion-oriented measure and the aesthetic-oriented measure were 0.81 and 0.80 respectively.
Data were analyzed by using the Hayashi's Quantification Theory I in which the independent variables were the socio-psychological characteristics and the dependent variables were the fashionoriented behaviors. Analysis indicated that a significant relationships do existed in the clothing behaviors and the socio-psychological characteristics and that “curiosity” and “delinquency” in the socio-psychological scales were important variables relating to the fashion-oriented behaviors. For the aesthetic-oriented behaviors, “conformity”, “delinquency”, “sensitivity”, “curiosity”, “femininity”, and “selfdisplay” were found to be variables greatly contributed to the relation.
