The purpose of this study was to develop a new basic skirt pattern for 4 lower body types of Plus-sized women. To reduce a time and economic loss about putting it on, This study applied a 3D sample module in the course to develop a basic skirt pattern which is fit, functional and beautiful. A data analysis used the SPSS 11.0 statistics program. To verify the difference, This study used the variance analysis and Duncan's test for the postmortem verification. The result was as follows. To reflect a feature according to an abdomen projection and hip projection, we added the maximum hip circumference to the waist circumference and hip circumference for necessary for a skirt draft item. The front hip circumference sets to the H/4+1cm(ease)+D/4. The back hip circumference set to the H/4+0.5cm(ease)+D/4. The D is the hip circumference in the maximum hip circumference to subtract. The front waist circumference sets to the W/4+0.5cm(ease)+0.5cm(A front and back's difference)+D/4. The back waist circumference sets to the W/4+0.5cm(ease)-0.5cm(A front and back's difference)-D/4. Compare with 4 lower body types of Plus-sized Women, A type 2 and type 4 abdomen projections are bigger. We raised a front waistline of skirt pattern to a 0.3cm upside, and take about 1.3cm down the skirt length from a developed skirt pattern. Consequently, the appearance of a front skirt length was improved with a side skirt length.

In this study 61private brand skirts and 67 brand name skirts were compared to see if the skirts from the different markets were suitable for both comfort and movement. The researcher chose size 66 skirts with a waist circumference of 68~70cm and hip circumference of 92cm. The resets are as follows. (1) In the waist measurement, the minor brand skirts were made at the maximum measurement (70cm) and the department store brand skirts were at the minimum (68cm). (2) Compared with the standard back split length of 9cm for a 48cm-long skirt, the minor brand skirts had a split of only 4.5cm, while the department store brand skirts were 3cm less (split length-6cm). From this result, we see that both of them are less practical than they are supposed to be (3) For the department store skirts, the hip circumference and waist circumference show a significant correlation to skirt length (p<0.05) and back split length (p<0.001). Larger waist & hip measurements equal longer split length. For the minor brand skirts, the length of the split shows a significant correlation to the depth of the hem-line Shorter split equals smaller hem depth. From these results, it can be concluded that the two groups of skirts do not differ except for back split length and waist circumference, but regarding the split length, both of them should be modified for else of movement and comfort.

From the menopause, women's aging progress is accelerated. Changes of lower body somatotype are accentuated in abnormal of body index and proportion. The purpose of this study is making more functional, more beautiful and more comfortable slacks for the postmenopausal women who actively participate in social activities. The results of this study are as follows: As the characteristics of this study pattern, hip circumference was replaced with maximum lower body circumference, the crotch length was defined as H/4, front crotch extension was H/16 and back crotch extension was defined as H/8. The center backline was set up with half of crotch level line. As characteristics of style, waist line is lowered 2cm at the center front, 1cm at the center back with a little bent waistband. Knee line was set up heightened 6cm from crotch level to the ancle, and widened the width of the knee and ancle, and made in semi bell bottom. 6 women who put on slacks designed from their body size evaluated that their experimental slacks were superior than ready to wear.

The purpose of this study is to provide a basic pattern to assist in the development of formal pants that reflect the physical characteristics of women with lower-body obesity. The subjects selected for this study were women in their 20s and 30s with a Rohrer index of 1.6 or higher, a waist circumference 78.5cm to 83.5cm, and a lower drop of at least 18cm. The experimental pants patterns were developed by varying the waist line position, the waist ease, the ease in the hip area, the crotch length, the front and rear crotch width, the leg width, and the total length. Data analysis was performed using the SPSS statistics program(version 18.0). To verify the difference, this study used a variance analysis and Duncan's test. The conclusions drawn by the study are as follows. To reflect the form element of an abdomen with fatty deposits, the waist circumference should have an ease of 2cm. The front waist result was W/4+0.5cm+0.75cm and the rear waist result was W/4-0.5cm+0.25cm. The hip circumference showed a total ease of 4.5cm. The front hip result was H/4+0.75cm and the rear hip result was H/4+1.5cm. The crotch width set to H/16-1cm and the applied rear crotch width was H/16+2cm. The rear hip area was given more ease to reflect the protrusion of the hip. Along the line extending from the knee area to the crotch line, the outer seam line was designed with a gradual S-shaped curve to accommodate the protrusion from the maximum thigh width.

Obesity has been directly associated with the development of hypertension and cardiovascular disease. The purpose of this study was to investigate the blood pressure response during graded exercise test in obese adults. 189 subjects (age: $47.96{\pm}10.23$) were assigned to two groups: non-obese group (N=105, BMI: $22.05{\pm}1.57$, waist circumference: $76.90{\pm}6.17$) and obese group (N=84, BMI: $26.96{\pm}2.51$, waist circumference: $88.29{\pm}6.41$). The subjects underwent health screening and exercise treadmill test from January 2012 to December 2014. Graded exercise test was performed according to the Bruce protocol. Exercise duration (P=0.046) and METs (P=0.015) were significantly lower in obese group than non-obese group. There was no difference in the rate of change in blood pressure response between obese group and non-obese group during exercise, and the recovery rate of systolic blood pressure was delayed in the obese group compared to non-obese group in the first recovery period (P=0.020). The significant factors of increasing rate of change in maximum systolic blood pressure was waist (P=0.046) and hip circumference (P=0.008). In conclusion, these results demonstrate that, for hypertension prevention in obese adults, waist and hip circumference levels should be managed within normal range.

In this study, fitness tests for slacks were divided into shape fitness test and motion fitness test, and the fitness test conditions for slacks were designed as the first step for standardization of measuring scales. Shape fitness test consisted of analyzing the parameters of appearance sensory tests as described in preceding studies, performing a simulated appearance sensory test, collecting and considering apparel experts' opinions about the test parameters, and establishing test conditions in terms of test regions, descriptions and faces. For the regions of the abdomen, hip, crotch, thighs, and knees, the parameter of unnecessary wrinkle/stretch was observed from the anterior and posterior body, and then evaluated; for waist, hip, crotch, knee and hem circumference, the parameters of ease and horizontality were observed from the anterior body and posterior body followed by evaluation; and, at the levels of waist, hip, crotch, knee and hem circumference, the division of the lateral line were observed from the lateral body followed by evaluation. Motion fitness test was composed of reviewing and analyzing comparatively the methods of motion fitness tests as mentioned in preceding studies, and establishing test conditions in terms of test motions and test regions. For each of the waist, abdomen, hip, crotch, and knees, wear sensation was tested in the positions as follows: upright standing, moderate walking, chairsitting, bending forward to the maximum, and kneeling down, provided that as the measured points of garment pressure, anterior waist, abdominal protrusion, buttock protrusion, crotch, and midpatella were set and tested.

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.

The study aimed to evaluate the appearance of the men's work clothes jumpers developed to suggest the prototype work clothes jumper patterns by using the 3-D clothing simulation technology. The 3-D simulated clothing images considered the upper body features of men in the age range between 20 and 59 in South Korea. A questionnaire survey conducted previously suggested a basic jumper style with shirt collar and snap opening cuffs for the heavy industry workers; and discomforting parts of the work clothes jumper of the subject workers have been referred to for the experimental jumper appearance test. Besides, defining the measurements of men's upper bodies enabled to generate the men's 3-D virtual models representing each age group's average body feature. The significant body measurement factors for men's 3-D body modeling and jumper pattern-making were stature for the height factor; chest, waist and hip circumferences for the circumference factor; waist back, hip and arm lengths and interscye front/back for the length factor; and back neck breadth for the breadth factor and armscye and scye depths for the depth factor. The men's body measurements of 30's were implemented to three experimental jumper pattern-making methods, i.e. the 1st method using the relations based on stature and chest circumference; the 2nd method using the direct body measurements; and the 3rd method adopting the maximum ease amount of given body measurements whether relations or direct measurements except the direct measurement of scye depth. A comparison among the three experimental jumpers' simulated images highlighted that the appropriate ease amount of the jumper gained higher scores in terms of the jumpers' front, side, back and sleeve parts and the total silhouettes. Therefore the 3rd experimental jumper was finally selected for the heavy industry workers.

This study developed and proposed a pattern that can fit the body and compensate for the defects of the body type by applying shoulder princess line to the torso pattern and including formative characteristics of each object on the study of body shape's change in 40-59 year old middle aged women. The results of this study are as follows; First, according to the analysis of 'Size Korea 2010' such as average, standard deviation, minimum value, and maximum value of 48 items, women showed increase in most of the items except height as they became aged. Second, factor analysis was made to understand the shape component factors of middle aged women and to use them for the body type classification. Third, cluster analysis was made according to the shape of front and sides which should be considered in pattern production based on the factor analysis results, and the body type with the measurement values most similar to the average of direct measurement of 'Size Korea 2010' was set as standard. Fourth, in designing torso patterns through the $1^{st}$ and the $2^{nd}$ wearing experiments according to the body type, body shapes such as Chest Circumference, Waist Circumference, Hip Circumference, and Waist Back Length were considered in pattern design, goodness-of-fit was enhanced with difference in margin according to body type and different margins in front and back, and fitting satisfaction was improved by applying princess line.
