The growth of the middle school girls show big difference among the individuals and the development of each area of the body is not uniformed but diverse which could be understood as the period that the problems on the fit of the clothes occur extensively. Therefore, in this study, the somatotype of the middle school girls are intended to be categorized for the highly applicable clothes design. For this, the 3 middle schools in Jeonju were selected for anthropometric measurement of 324 middle schools. The items of measurement are related to the somatotype of middle school girls, clothes design which is consisted of total of 50 items. For the basic data of clothes was judged that the classification of somatotype related to the tops and bottoms would be rational; hence, it is classified into the upper part and lower part of the body to extract the body shape consistent factor. As a result of analyzing the factors, the upper body consistent was extracted as the 4 items: upper body circumference, upper body length, breast growth and arm length. It was displayed as 75.26% explicability. The lower body consistent factors are extracted as lower body height, lower body circumference, hip length, and rear shape with 78.62% explicability. To classify the somatotype of upper body and lower body, each factor score is made into the independent viable for group analysis. As a result, the upper body was classified into the 'upper body with small breast and long' and 'upper body with big breast'. The lower body was categorized as 'lower body with long hip length' and 'standard lower body'.

The aim of this study was the kinematics and kinetics analysis of the movement of throwing a ball between boy and girl middle school students. The subjects of this study were seven boys and girls respectively and all of them were middle school students. T

본 연구는 과외 스포츠활동이 여자중학생들의 신체적 자기개념에 미치는 효과를 검증하기 위하여 학년별, 1회 참여시간, 주당 참여빈도에 따라 신체적 자기개념을 분석하였다. 연구 대상자는 Y시에 소재하는 J여자중학교 1, 2, 3학년 학생들 중 방과 후 과외 스포츠활동에 참가하는 학생들 267명이었으며, 신체적 자기개념 수준은 10개의 하위요인으로 구성된 한국어판 PSDQ(Physical Self-Description Questionnaire)를 이용하여 자료를 수집하였고, 다변량 분산분석(MANOVA)을 사용하였다. 분석결과 학년에 따라 체지방, 외모, 자기존중감 요인에서 그룹별 차이가 있었으며 3학년이 1, 2학년보다 높은 수준으로 자신을 인식하고 있었다. 1회 참여시간에 따라 스포츠유능감, 건강, 신체활동, 지구력, 신체전반에서 그룹간 차이가 있었으며, 1시간 이상 참여하는 집단이 다른 집단보다 자신의 신체를 높게 평가하고 있었다. 주당 참여빈도에 따라 스포츠유능감, 건강, 신체활동, 자기존중감, 유연성, 지구력에서 그룹간 차이가 있었으며, 주당 참여빈도가 많은 집단이 자신의 신체를 높게 평가하고 있었다.
