A Biotechnological Study on the Sleeve Form Variation according to Arm Movements for Elementary Schoolgirls

학령기 어린이의 상지동작에 관한 인간공학적 연구

The objectives of this study are to investigate the variation of the sleeve form by changing arm movements and to study the relationship among the three aspects of sleeve (sleeve height, width and armhole girth) by changing arm movements. Plasrun gyps were used for this experimental research. The subjects of this study were elementary schoolgirls (9$\~$12 years old). Arm mevements were 4 types($0^{\circ},\;45^{\circ},\;90^{\circ},\;135^{\circ}$) to the vertical directions. The statistical methods used to analyze the data included mean, standard deviation, the Pearson's correlation coefficients and coefficients of determination. The results obtained from this study were as follows; 1. According to the arm movements, the sleeve form changed more in the front than in the back. 2. As the arm movements were increased vertically, the heights of sleeves and the girths of the armholes were decreased, and the widths of sleeves were increased. 3. Variation rates by changing arm movements were different according to the variation of arm movement, and were the highest in sleeve height. 4. There was a negative correlation between sleeve height and width, and a positive correlation between sleeve height and armhole girth.
