This study aimes to investigate the garment ease of pe-school children's clothing in accordance with arm movement. The experiment was done with 4 per-school children fro mage 3 to age 5, and 3 types of experimental clothes were made ; sleeveless, half sleeve, and long sleeve. The waist pattern and the sleeve pattern of each experimental clothes has no garment ease. And experimental clothes were examined to obtain the necessary ease of armcye line and waist lien by cross-cut method. The results of investigation can be summarized as follows ; 1. The resulting movement ranges of experimental clothes with no garment ease were 131.5°(sleeveless), 71.75°(half sleeve), and 62.25°(long sleeve). 2. The size order of cross-cut opening of waist lien movement were (side>front>back), and (half sleeve>long sleeve>sleeveless). 3. When the base point of measurement was set to armpit point by arm the latitudinal length of cross-cut opening of armcye line by arm movement was (anterior armpit part > posterior armpit part), and longitudinal length of cross-cut opening was (upper part>lower part).

The objectives of this study were: 1. To investigate the relationship between arm movement and clothing pressure in the upper arm and shoulder blade area. 2. To find out the relationship between ease of basic pattern and clothing pressure in the upper arm and shoulder blade area. 3. To study any interaction between arm movement and ease of clothing on the clothing pressure. This study was an experimental research using the measuring devices of clothing pressure. The subjects were the unmarried college women. Arm movements were 3 types($45^{\circ}$, $90^{\circ}$, $135^{\circ}$) to the horizontal direction. The ease of basic pattern in the breast was 3 types(4 cm, 6 cm, 8cm). The statistical analyses used in this study included mean, standard deviation and one-way analysis of variance. The results obtained from this research were as follows; 1. The whole clothing pressure increased as the angle of the arm movement increased. Part of upperarm and shoulder blade above axillar gave high clothing pressure while part of upperarm and shoulder blade above upper breast, low pressure. Difference between highest clothing pressure and lowest clothing pressure increased as the arm movementdid. 2. The whole clothing pressure increased as the ease of the basic pattern in breast decreased. No matter how the ease of basic pattern in the breast area varied, the Points where generally showed high and low pressure were identical. 3. The whole arm pressure increased as the movement angle increased and the ease of pattern in breast area decreased. Difference between highest clothing pressure and lowest clothing pressure increased as the movement angle increased and the ease decreased.

The purpose of this research was to analyze the relationship between the ease of crotch depth and the mobility of leg movement. Ten Korean men were participated as subjects and 0. 3, 6cm of crotch ease were inserted for test clothes. To analyze objectively, range-of-motion of four selected movements was measured by Leighton flexometer and goniometer. Also. wearer acceptability rating was measured for subjectively investigation. Anova and Duncan's range tests were used for statistical analysis. According to the results, 3cm of crotch ease was most comfortable. The mobility of test clothes with 3cm crotch ease was improved largely in every test movement(16.2% and 16.6% in segittal plane, and 6.1% and 6.2% in frontal motion).

The purpose of this study was to suggest the proper ease of total crotch length concerning both appearance and comfort. The research processes as follows. 1) For the purpose of obtaining the necessary ease of slacks in body movement, experimental slacks of no ease of total crotch length were made. Three college girls putting on these experimental slacks were examined on their back middle waist lines using cross-cut method. 2) Experimental slacks for suggesting the proper ease consist of 7 types; slacks CO, Wl, W3, W5, W7, C3, C5. The sensory evaluation for appearance and comfort was applied to evaluate the 7 slacks. The results can be summarized as follows. 1. As the leg-movement angle increased, the vertical space increased and the horizontal space decreased. There was negative relationship between vertical and horizontal space. And as the leg.movement angle increased, the area of space increased. The shapes of space showed the amounts of space and the direction of force by the movements. 2. The appearances of slacks C3, W3, C5 were better than the other slacks. The eases of the crotch were better than those of the waist line in appearance. And slakcs W7 was better than any other , ;lacks in comfort. When the amount of each part of eases was same, the comfort in eases of crotch was not as good as that of waist line. 3. In slacks, the proper ease of total crotch length was 3% and 5% of total crotch length.

The subject, in the blouses that sleeve caps and sleeve lengthes are different from, did sensory test by right arm movement and both arms movement. This sensory test which is used in fabric good, is Shef's. RESULTS : 1) The ease of bust size is very significant by cap height, at 5%, 1% level by sleeve length. 2) The front area of arm hole is affected by cap height, sleeve length movements more than the back and the under area of arm hole are 3) Sleeve width is affected by cap height, sleeve length both arms movement. That is, they should be designed according to the use because they affect the ease of blouse very much. Especially bust size should be considered with sleeve pattern because the ease bust becomes different with sleeve pattern.

This study aims to suggest the proper ease for slim-fit jackets according to the number of buttons from a one-button jacket to four-button jackets for men in their 30's. The researchers carried out both an appearance evaluation and movement functionality evaluation. The results are as follows: When conducting the appearance evaluations, meaningful differences were found. The one-button jacket showed high scores for the 7.5 cm ease. The two-button jacket and the three-button jacket showed high scores for the 10.5 cm ease. The four-button jacket showed a high score for the 13.5 cm ease. Next, the results of the movement functionality evaluation showed the same trend; as the ease was increased from 7.5 cm to 13.5 cm, the scores increased. This is because if the garments offer more ease, this gives room for actions. Additionally, it showed that if there were fewer jacket buttons, then the results showed a high score. The researchers believe that if the number of jacket buttons is lower, then the area of the V-zone increases, so that there is more room for movement. The study suggests a proper chest ease of 7.5 cm for the one-button jacket, 10.5 cm for the two-button jacket and three-button jacket, and 13.5 cm for the four-button jacket, respectively.

This study was to compare and analyze the clothing pressure according to arms movements of 4 brands jacket for middle-aged women group by measuring clothing pressure of each brand. The results were as follows: 1. According to the analysis of jackets of 4 brands, in general, jacket C had the largest ease amount. while jacket A had a large ease amount in waist, hip areas compared with bust area. Also jacket B had a small ease amount in bust, waist areas and jacket D had a small ease amount in hip areas. Therefore the ease amount is different between each brand, each size even though jacket designs are similar. 2. It was found that clothing pressure was affected by arm movements than jackets. Since this study was limited to the arm movement for motion variation, it was recognized that a significant difference among each jacket and each movement at shoulder, waist parts existed with relation to this motion. 3. Parts showing a significant difference among each size were bust point, abdomen point, center back point of abdomen level, angulus superior scapulae point and center back point of waist level. Also clothing pressure of size B91 was bigger than size B88 except Center back point of waist level. 4. Clothing pressure in shoulder point, front armpit point, back armpit point, upper arm point areas increased as the angle of the arms movement increased. Also, individual variation of clothing pressure in front armpit point, back armpit point, armpit point and upper arm point was large, and clothing pressure in abdomen point was high in M5(sitting posture).

This study is to research on the rate of expansion or contraction according to movement of the lower body of the man their twenties using Rapid Form software. And aim of this study is to get information of ease allowance in developing slacks pattern using 3D body surface scan data through comparison with existing slacks patterns. Considering on the contraction and expansion according to movement, it need to set the more ease allowance in hip circumference than waist circumference, and the more ease allowance in back hip width than front hip width in slacks. In crotch length, the length of front crotch is revealed contraction but the length of back crotch is revealed expansion. It is desirable lowering front waist line and raising back waist line to possess ease allowance in back crotch area. The length of side seam is revealed a little expansion but the length of inseam is showed a great expansion. To develop slacks pattern of scientific approach using 3D body surface scan data, it need to analysis the rate of expansion and contraction of the lower body based on the movement, shear deformation, slip in fabrics and skin, or in fabrics and fabrics, and slip down from waist line.

This study is concerned with the functional utility of movement in sleeve from an ergonomic viewpoint. Experiments were carried out which include 43 upper extremity segments, 21 motions and 35 female subjects. The major conclusions of the study are. 1. The expansion rate of upper extremity was higher in length than in circumference mesurements. The amounts of expansion were, especially high (more than 60mm) for inner arm length, axillary arm circumference, and outer arm length. Therefore, a lot of ease is necessary for these parts. On the other hand, armhole circumference, forearm circumference, and wrist circumference had low rates of expansion. The sleeve cap length was also contracted in all motions. 2. The expansion rate and the range of expansion and contraction were higher in the upper arm than in the forearm. The main points of expansion were the axillary and elbow parts. The segment of maximum expansi (rate of 44.8%) was Iii of axillary parts. As the body surface expands mainly in some segments, it is desirable to allow ease to the main segments of expansion. 3. In a basic sleeve, necessary ease was lacking in the measurements for outer arm length and axillary arm circumference, while it was too large in armhole circumference, forearm circumference, wrist circumference, and sleeve cap length. Therefore, a basic sleeve is inadequate as a functional sleeve for hard work in point of functional utility of movement. Wider application of these findings would lead to an improvement in the comfort of workers.

The purpose of this study was to analyze the patterns of D level protective clothing, improve their ease of movement by modifying the patterns, and validate the effectiveness of the improvements through 3D virtual fitting and subjective wearing evaluations. Based on previous studies that identified numerous complaints, the patterns of the neck, armpit, and waist areas were modified, resulting in the development of new patterns. To compare and analyze the improved protective clothing with the basic protective clothing, stress and strain were examined after 3D virtual fitting. Additionally, to assess the clothing's allowance, the overall distance between the avatar and the protective clothing, as well as the sectional circumference length and distance of each avatar body part, were measured. Furthermore, the improved protective clothing was manufactured, and a subjective wearing evaluation was conducted with ten males in their twenties as participants. The results showed that the improved protective clothing had evenly distributed stress, larger sectional circumference, and lower average cavity distance. The subjective wearing evaluation also revealed that the suit with improved patterns exhibited superior size suitability, reduced pulling sensation in different body parts, and increased ease of movement. In conclusion, this study confirmed that even minimal pattern modifications can enhance the functionality of protective clothing, alleviating discomfort for wearers.
