This study was to provide the fundamental data for a scientific and rational clothing construction by investigating the length variation of the upper arm surface, using the method of surgical tape, and to understand the expansion and contraction of parts of body for the making of clothing adaptable to movement. The subjects were li early elementary schoolgirls in Busan area classified with three somatotypes, and arm-movements consisted of 6 types. The statistical analyses used in this study were mean, standard deviation and the ANOVA and LSD procedure. The results of the analysis of the length of the upper arm surface are as follows: By arm-movements, in the items of horizontal, upper arm length changed more in the front than in the back, and in the items of vertical, represented the opposite of horizontal items. In the items of upper arm, the anterior-posterior axilla length and under arm length were influenced by arm-movements, and the under length of the upper arm represented the maximum rate increase of 74.59%(3.20cm)$\sim$138.72%(4.28cm). In the somatotypes of early elementary schoolgirls, type II was more influenced by arm-movements, and for the making of clothing adaptable to movement, type III needed to reflect more surplus length(2cm) than the other types.

This study aims at designing sleeves which are suitable for arm shapes and arm movements. With the samples of of ordinary 24 women aged from 20 to 22, the arm shapes and movements were measured 3-dimensionally using a motion analyzer and a sonic digitizer, and then clasified into three characteristic types (A, B, and C). Our analysis leads to the following conclusion. The factors classifying arm shapes are the length from acromion to posterior armpit point, arm hole length, the cap height, difference in height between anterior and posterior armpit points, armhole circumference, upper arm circumferemce, armhole depth, and underarm circumference. The characteristics of arm type A is that the armhole depth and the length from acromion to posterior armpit point are the largest, while the circumference inbe- tween upper arm and elbow is the smallest among the three arm types. Thus, the large circumference difference between upper and lower arms is the most notable in arm type A. The factors classifying arm shapes for arm type B are the smallest except for the circumference inbetween upper arm and elbow which is larger than that for arm type A. The circumference difference betweemn upper and lower arms is small for arm type B. Arm type C has the smallest armhole depth, while other factors are similar to those for arm type B. In type C, the size of upper arm is comparatively small on the frontal plane, while it is the largest on the sagital plane.

This study was done to analyze the surface development of upper arm for planning sleeve armhole line. The major conclusions of this study are: 1. The surface development by arm movements made the expansion and contraction of upper arm surface changes easily visible. Armhole lines of 90$^{\circ}$and 135$^{\circ}$~180$^{\circ}$movements deviated from those of standard posture. 2. According to regression analysis, armhole lines on the upper arm were adapted to sleeve patten, following the axillary circumference line changed to biceps line. Sleeve cap length ranged from armhole/4+2.5cm to armhole/4$\pm$0.5cm. 3. Compared to Rim's pattern method, ascending and descending amounts of armhole lines were represented as fixed values.

In our previous work using a motion analyzer and 3-dimensional sonic digitizer, the arm shapes for 23 women in their early twenties were classified into three characteristic types. In order to design sleeves, suitable for arm movements for the three characteristic arm shapes, a relationship between arm length variation and shoulder/elbow angles has been investigated for four cases of arm movements (flexion, extension, adduction and abduction). Each arm movement can be characterized by the changes in shoulder angle and the changes in elbow angle at the maximal shoulder angle. In all the four cases of arm movements, the changes of shoulder length and cap height are largest at the maximal shoulder angle. These changes were little affected by changes in elbow angle. The changes in the lower arm length and the difference between cap height and upper arm length are the largest at the maximal elbow angle of the maximal shoulder angle. There is a linear relationship between cap height and shoulder angle during arm movements; thus, in designing sleeves the cap height can be determined from the regression of cap height vs. shoulder angle.

A clothing-erogonomics study was performed to investigate the difference of the upper arm skin skin surface and the relationship among the three aspects of upper arm (height of sleeve rap, sleeve width and armhole girth) by changing arm movements. Plaster cast was used for this experimental research. Arm movements consist of 9 types; just carmly standing on ($0^{\circ}$), and each 4 types ($45^{\circ},\;90^{\circ},\;135^{\circ},\;180^{\circ}$) to the vertical direction in front and in side. The results were as follows; 1) As the arm-movement angle increased, the height of sleeve cap decreased and that ratio was largest in the portion A-B3. 2) The steeve width was enlarged with the increment of movement angle in all portions of upper arm except B1-B5. 3) As increasing the movement angle, the whole armhole girth decreased and the ratio o(front armhole girth (F-A) was larger than that of back. 4) In the vertical direction in front, the height o( the sleeve caps was larger, the sleeve widths were smaller than in the vertical direction in side in all movement types, but there was no significant difference in arm-hole girth between the two cases. 5) There were significantly negative relationships between measurements in height of sleeve cap and those in sleeve width, and also between those in height of sleeve cap and in arm-hole girth. And significantly positive relationships were found between neasurements in height of sleeve cap and those in arm-hole girth.

This study was done to analyze the body surface developments of armhole area. The major conclusions of this study are: 1. The body surface developments showed the characteristics of expansion and contraction of body at armhole area. By arm movements, front armhole lines on the body surface developments of upper arm were slow going, but back armhole lines were full and round. As a whole, armhole line of the back torso was swollen outside especially at backarmpit point area, it seemed like a line of raglan sleeve. 2. Regression Analysis was carried out to adapt armhole line on the upper arm and upper body to bodice and sleeve pattern, following the axillary circumference line and chest breadth line changed to the basic pattern form. As the result, armhole lines of 90$^{\circ}$ and 135-180$^{\circ}$ movements deviated from those of standard posture. U-type, clear armhole curve of standard posture turned to V-type, slanting line by arm movements.
