2D 데이터에 의한 여고생의 발바닥 유형 분석

Abstract

This study classified the type of sole for female high school students and analyzed the characteristics of each type by the shape of the sole (plantar view) using 2D scan data. The data were collected from a foot anthropometry of 310 female high school students in Gwangju and Jeollanam-do. Left feet and right feet were measured indirectly by using flatbed scanner. The sole anthropometric measurements consisted of 24 items. The results of the investigation into the differences between left and right feet soles by the 2D measurements data indicated that there was no significant statistical differences in the length of items. The left sole had higher values than right sole in the width items and angle items; however, the lateral side of the right feet projected to the outside more often than left feet. In analyzing foot sole of female high school students, the shapes of sole were classified into three types. Type 1(41.94%), Type 2(36.77%), Type 3(21.29%). The most characteristic sole type for female high school students was Type 1. Type 1 referred to a narrow foot width with little or no curvature of the toe. Type 2 represented the longest foot, with foot width shown as a spacious and distinctive feature in width at the medial area of the foot. Type 3 represented the shortest and widest of ball width, gathered inside toe 5, and lateral side as the most projected among the three types.
