The Evaluation of Movement Functionality on Improved Pattern-Design Working Uniform of Construction Site Worker

The purpose of this study is to examine the functionality with improved pattern-design working uniform(protocol, P) and current working uniform(control, C). Movement functionality evaluation of improved pattern-design working uniform was carried out through sensory evaluation of working uniform. Movements for the sensory evaluation consisted of four types of up and down and horizontal movements of the shoulders, four types of waist movements and five types of knee movements. The results have been shown as follows: The sensory value of back girth, wrist, side seam area of the "P" with the posture of raising an arm forward up to $90^{\circ}$ and the maximal arm's vertical movement significantly improved compared to the "C". Therefore, it can be concluded that movement functionality was increased with the improved pattern-design working uniform in the respect of arm's up and down movement. Furthermore, for P, Movement functionality improvements were shown in P with arm's horizontal movement, waist bending movement, and knee movement. Current working uniform(C) is jumper-type which wa designed without consideration for movement functionality of the arms and legs. But Pattern-design uniform(P) which was developed in this study. Therefore, the more patterns development, the better movement functionality in working uniform. The improved movement functionality improvements in working uniform will provide not only personal pleasantness but also efficiency of productivity at construction sites. In respect of human body's movement, further study for improved working uniform is required.
