We consider the irrational part of the basic pattern drafting of the Geo-Ko-ri so that we want to design it more scientically. So there are problems which is found after we considered with comparison about the existingly basic pattern drafting of Geo-go-ri. (1) there is a difference between the practical and Calculation. (2) The part of the curved line was mad indistinctly There is a difference betweence the calculating expression and calculating value. (4) There are some parts which lack objectivity about the reference size. (5) The calculating method of Collar-width and Neck-Nidth are not formative and rational. These are items that we must consider and study further. Especially if we can make up of the scientific form in consideration of the formativeness focused on "git" I think it will make a great contribution to not only the standardization of the basic pattern of Geo-go-ri and the use of the use of education but also the manufacture of individual clothing the production by Auto CAD. Auto CAD.

Underwear made of plain and 1$\times$1 rib-knit cotton fabric were laundered to evaluate the change of the size and the tensile properties. For laundering pulsator and drum washers were used. After 30 washing cycles the amount of shrinkage and the extension were different with washer types. Underwear laundered by the drum type was shrunken in the neck line armhole line and hem line were extended and the bodice width and side length were shrunken,. Tensile strength of the knitted fabric was not decreased through repeated washings because the fabric density was increased. But it was confirmed by SEM that the surface of the fiber was damaged by washings.

The purpose of this thesis was to develop torso patterns according to the physical types of men in 20s. The procedure and results are as follows; 1. Of the men in 20s meeting the national average of physique, 4 men were selected and classified into 2 physical types according to their chest and waist circumference drops. One group had 20㎝ drop (Y type) while the other had 16㎝ drop (N type). Through evaluation performed by clothing construction professionals on the 4 upper bodice blocks drafted according to the existent drafting method and dressed on the 4 men, several problems have been found. These problems were adjusted and supplemented to make two new blocks. The fit of the new blocks were evaluated and proved to be satisfactory. 2. The following is the adjustments made to the existent men's torso patterns which had been utilized as the objects the first evaluation experiment. ① Though the back waist length of the pattern from the existent drafting method covered the center back length of the body in both Y type and N type, the front length did not causing it to stand away from the body. To adjust this, 2.0㎝ has been added to the center front length of each pattern so that the waist line could make a bar level to the ground. ② The shoulder line of the pattern from the existent drafting method had the tendency to fall backward. To make the shoulder line to fall in place, it has been moved 1.0㎝ to the front. 0.5㎝ has been added to the should length. ③ The neckline had a tendency to climb up. It has been lowered by 0.5㎝ until the line touched the center front neck point. ④ Though different in degree, the neck circumference did not allow enough width for both physique type causing the neckline to pull at side neck point with diagonal crease. To adjust this, 0.3㎝ and 0.6㎝ has been added to the Y type and N type respectively so that the neckline would touch the side neck point and the neckline could naturally fall into its original position. ⑤ Though different in degree, there was not enough space at the armhole causing wrinkles around this area. Therefore, 0.25㎝ and 0.5㎝ has been added to the front and back of the armholes of the Y and N types respectively. The armhole was made 1.0㎝ deeper only for the N type. ⑥ 1.0㎝ in the front and 0.5㎝ in the back were added to the side scam for the Y type while 0.5㎝ in the front and 0.25㎝ in the back were added for N type. This eliminated the unwanted wrinkles to give the silhouette a smooth look.

This study was performed to investigate the effect of suboccipital stretch on the head and neck posture and the electromyographic(EMG) activity of some cervical muscles. For this study, 39 patients with temporomandibular disorders(TMD) and 34 dental students without any signs and symptoms in the masticatory system were selected as the patients group and as the normal group, respectively. Head position by goniometer CROM$^{(R)}$(Performance attainment, St. Paul, USA), EMG activity by BioEMG$^{(R)}$(Bioresearch Inc., Milwaukee, USA), and craniocervical posture by cephaloradiography were observed in both natural head posture(NHP) and head posture with suboccipital stretch(tuck posture) abtained from slight posteroinferior finger pressure on the chin. Variables measured on the cephaloradiograph were SN angle, atlas angle, CVT angle, occiput-atlas and atlas-axis distance, and pharyngeal width. The data obtained were analysed by SPSS windows program and the results of this study were as follows : 1. In the sagittal plane, degree of anterior rotation of the head by suboccipital stretch was 6.3 in the patients group, and 6.2 in the normal group, respectively. So there was no significant difference between the two groups for degree of anterior rotation, but the position of the head in the patients group were more posteriorly extended than in the normal group in both NHP and tuck posture. 2. EMG activity of the stemocleidomastoideus in the patients group, and that of the upper trapezius and the sternocleidomastoideus in the normal group were increased by suboccipital stretch. The range of EMG activity, however, in these cervical muscles were 1.6 -2.3)u.V. 3. Cephalometric variables such as SN angle, atlas angle, CVT angle, occiput-atlas and atlas-axis distance except pharyngeal width were generally increased by suboccipital stretch. There was some difference, however, in results between the two groups. Atlas angle was not changed in the patients group whereas CVT angle was not changed in the normal group. 4. The distance from subocciput to spinous process of axis was significantly increased as much as 3.0mm in the patients group, and 3.7mm in the normal group by suboccipital stretch.

This study classified the body shapes of Korean obese women and investigated the differences of each body shape, using 2004 Size Korea data. For selecting the obesity sample, 7 obesity judgment indices were chosen through previous clothing-related studies. A total of 636 females defined as "obese" by 5 out of 7 indices were selected as subjects and 54 body measurements and obesity judgment indices were used in this study. Firstly, mean, standard deviation, minimum, and maximum values of each measurement and item were obtained from the descriptive analysis of 53 measurements. According to the descriptive analysis, all measurements and obesity judgment indices of the subjects demonstrated a serious obesity level shown by BMI 27.11, R$\ddot{o}$hrer index 1.76, Vervaeck index 104.77, Relative weight 133.00, WHR 0.90, and waist circumference 86.71cm. In addition, the measurements and indices showed considerable differences between minimum and maximum values. Significant differences were identified in all measurements and items at a significant level, p=.001. Each distribution of body types according to age, stature, bust, and waist circumference groups was provided in this study. Secondly, factor analyses were conducted using 38 measurement items to extract the body characteristics of obese women. Factor 1 was "circumference measurements & obesity judgment indices," Factor 2 was "heights & arm-related lengths," and Factor 3 was "size and ratio of waist circumference & hip circumference." Factor 4 was "lengths in upper body," Factor 5 was "back width in upper body," Factor 6 was "side neck point to bust & bust circumference," Factor 7 was "length in lower body & arm circumferences" and Factor 8 was "neck base circumference & front width in upper body." These 8 factors explained 76.54% of the total variance. Finally, 5 body types were selected in the cluster analysis. Type 1 (with big back widths & arm circumferences) was 15.5% of the entire subjects, Type 2 (the shortest and fattest, with big upper body) was 18.8%, Type 3 (with big breast) was 27.8%, Type 4 (the tallest and longest in arm lengths, with the smallest arm circumferences and lengths in torso) was 22.5%, and Type 5 (with big hips compared to waist circumferences, smaller height and upper body) was 15.5%. Fundamental differences were identified in all measurements and items at the significant level of p=.001. In addition, each distribution of body type according to age, height, bust, and waist circumference groups was provided in this study.

Objectives : The purpose of this study was to investigate effects of long-term taxi driving posture on the balance of musculoskelectal system. Methods : The author practiced Moire topography by using IBS-2000 for 30 male taxi drivers and general people. Then we measured difference of contour lines, difference of shoulder joint height, interval between vertical baseline of pelvis and vertical baseline of neck, ratio of thoracic curve and lumbar curve, difference of width between right and left through Moire topography. After we statistically analyzed difference of Moire topography's data between long-term employed male taxi drivers and general people. Results : 1. Taxi drivers, difference of contour lines in scapular, lumbar, gluteal region was bigger than general people and significant difference(p<0.05) was observed between subject group. 2. Taxi drivers, diference of shoulder joint height was more large than general people and significant difference(p<0.01) was observed between subject group. 3. Taxi drivers, diference of interval between vertical baseline of pelvis and vertical baseline of neck was more large than general people and significant difference((p<0.05) was observed between subject group. 4. Taxi drivers, ratio of thoracic curve was more large than general people and ratio of lumbar curve was more less than general people and significant difference(p<0.05) was observed between subject group. Conclusions : According to above results long-term taxi driving posture might cause musculoskelectal system unbalance.

The purpose of study was to measure to body Surface area and the rational rate of Korean adult's women. The subjects are 20 years old to 49 years old women (Their bust width ranges from 74.5 to 101.5 cm, the height from 144.6 to 163.3 cm, the weight from 44.2 to 74.0 kg, Rohrer Index from 1. 02 to 1. 89). As the experimental method, both the gypsum method, by which the shape of body can be copied as it is, and weighing method, from which planed body surface area can be measured with consistant thickness of polypropylene film used. The results were obtained as follows. 1. After dividing the Korean adult's women into four groups (single and married women in their twenties, those in their thirties, those in their fourties). The change of body surface area was reviewed in accordance with age groups. No great difference among age group was showed in whole body surface area. 2. average value of body surface area is 1, 514m^2 and the part of trunk shows the biggest difference to the age groups. 3. After dividing the middle of body into two groups, the relation of symmetry of each parts is reviewed with difference in body surface area. The results shows that the part of head & neck and lower limbs are symmetrical. The part of trunk and upper limbs are unsymmetrical. 4. Regional rates of each part of whole body surface area are follows. head $4.98\%$, each-lobes $0.46\%$, neck $2.01\%$, face$2.48\%$, upper trunk $19.64\%$, lower trunk $13.91\%$, upper armpits $1.76\%$, lower armpits $12.52\%$, hands $4.64\%$, thighs $18.89\%$, lower legs$13.10\%$, feet $6.01\%$.
