The purpose of this study was to establish objective data for marketing of industries and product development design by researching popular singer fashion of Korea, investigating the preference for popular singer design in street fashion among adolescents on the basis of the research, and drawing an conclusion. To analyze street fashion, total 190 young men and women in their 20s, including teenagers, were surveyed mainly in downtowns around Daehakro, Gangnam and Hongik University. First, in relation to the upper garment, men were found to wear T-shirts and hood T-shirts the most, while women were found to wear T-shirts and one-piece dress the most. Second, in relation to the lower garment, the ratio of those who wore skinny clothes was high both among men and women. Third, in relation to the outer apparel, the ratio of men who wore casual jacket and hood zip-up was high, while the ratio of women who wore tailored jacket and leather jacket was high. Fourth, in relation to shoes, the ratio of men who wore sports shoes was high, while the ratio of women who wore heeled-shoe was high. Fifth, it was found that plane pattern was preferred the most. As it was stated above, the findings of this study on the effect of entertainers' fashion on adolescents through street fashion indicated that the number of adolescents who imitate the fashion of entertainers increased.

This study aimed to investigate the effect of differing heel heights on the electromyographic (EMG) activity in vastus medialis (VM) and vastus lateralis (VL) during stair ascending and descending activities. A total of 26 healthy women volunteered to perform stair-ascending and stair-descending tasks with 3 heel heights: barefoot, 3 cm, and 7 cm. The EMG activities of the VM and VL were recorded during the tasks. During the stair ascending and descending tasks, the EMG activities of both VM and VL significantly changed with differing the heel heights (p<.05). Moreover, the EMG activities of VM and VL during the stair ascending task were significantly higher than the corresponding values during the stair-descending task (p<.05). However, there were no significant differences between the VM:VL EMG ratios for the 3 heel heights (p>.05). The VM:VL EMG ratios between the 2 tasks differed significantly in the 7 cm high heel condition (p<.05). Despite an increase in the EMG activities in both VM and VL during stair ascending and descending tasks, there was no change in the relative EMG intensities of VM and VL, which was measured by calculating the VM:VL ratio this result indicates that no VM:VL imbalances were elicited. The relative EMG intensities of VM and VL during stair descent were lower than the corresponding values during the ascent, suggesting that VM and VL may show an imbalance in the eccentric activation during the weight-acceptance phase. This study provides useful information that will facilitate future research on how heel height affects muscle activity around the knee joint.
