This study analyzed Korean middle-aged men``s fashionable styles according to ageless trends as their representative characteristic and deriving their special features from men``s magazines. Literature and case studies were conducted together. The research findings are as follows. First, it showed uniformity, conformity, passive clothing selection and consumption in 1990s as characteristics of middle-aged men``s wear by period. However, clothing became an expressive way to pursue individuality and an ageless trend gradually, and middle-aged men positioned themselves as subjects of a consumer market for men``s wear after 2010 through active clothing selection and consumption. Second, along with a trend change preferring a comfortable and active to formal atmosphere, it showed that casual style became diversified and segmented gradually in Korean middle-aged men``s ageless trend and fashionable style. Third, as for formative characteristic changes in middle-aged men``s fashionable style by period, it contained a slim silhouette, bright and splendid colors and patterns, increase of light, active and functional materials, generalization of casual items and pursuit of individuality by various mix & match styles. Fourth, in Korean men``s ageless trend and changing fashionable style, four kinds of special characteristics were derived that included a change of the traditional clothing symbolism, weakened conformity & pursuit of personality, obscured boundaries between age and wearing style, and active embracing of a trend.

Purpose: The purpose of this study is to investigate the effect of visual and auditory stimulation randomly applied to healthy adults on walking. Design: Randomized Controlled Trial. Methods: Twenty-six healthy students in S college were randomly divided into visual feedback group (n=13) and auditory feedback group (n=13). The visual feedback group walked using four conditions. 1) In the red screen was shown, clap twice to the right, 2) In yellow screen, clap twice to the left, 3) In green screen, clap twice over head. 4) Do not clap in purple screen. The auditory feedback group walked using four conditions. 1)in red, clap twice to the right, 2) In yellow, clap twice left, 3) In green, clap twice over your head. 4) Do not clap in purple. All subjects measured gait variables before and after the test using G-walker. Result: The visual feedback group showed a significant decrease (p<.05) in the number of steps per minute, walking speed, and step length compared with that of normal walking. The auditory feedback group showed a significant decrease (p<.05) in the number of steps per minute, walking speed, and step length than that of normal walking. Conclusion: The results of this study suggest that visual and auditory stimulation applied to healthy adults may have significant effects on walking.

도시철도 이용객의 증가로 수도권 일부 정거장의 경우 일일 이용객 수가 20만명 이상이며, 특히 환승통로의 극심한 혼잡상황이 반복되고 있다. 이에 본 연구에서는 LOS등급별 밀도에 따른 속도 및 보행패턴 검증을 위해 보행특성 관찰이 가능한 모션인식 카메라를 이용한 현장실험을 수행하였다. 실험장소는 도시철도 대림역으로 역사 내 환승인원이 가장 밀집한 구간을 선정하여 평일 1일간 시간대별 밀도, 속도, 시간 및 행동패턴을 측정하였다. 도시철도 면적산정 시 평균속도는 1m/s이나 실험결과 LOS D등급은 0.8m/s, E등급은 0.58m/s로 분석되었다. 도출된 결과로부터 도시철도 이용객 LOS 수준을 효과적으로 예측 및 평가하고, 정거장의 개선 또는 신설 시 경제적, 효율적 면적 산정을 위한 기초자료로 활용하고자 한다. In the case of some stations in the metropolitan area by increasing of metro passengers, it is more than 200,000 the number of daily passengers. Especially serious congestion of transfer passage is repeated. In this study, it was conducted field experiments using the motion sensing camera capable of walking characteristics observed for the verification of the walking speed and the patterns of behavior in accordance with the LOS graded density. Experiment location is a metro Daerim Station. The transfer passage in the most crowded section was selected. Hourly the density, walking speed, time and the behavior patterns were measured for one weekday. The average speed in metro area estimates is 1m/s. The results of the experiment were analyzed to LOS D in 0.8m/s and LOS E in 0.58m/s. The LOS of metro passengers were effectively predicted and evaluated from the derived results. The results of this study utilized as a basic data to calculate an appropriate area when the improvement or construction of the station.
