This study aimed to compare and analyze the differences between the real flared skirts and the virtual flared skirts using the emulator function of CLO 3D. For this purpose, eight real skirts and eight virtual skirts were created by applying four types of fabrics (Muslin 30s, Polyester, Cotton Gabardine, Wool Blend ; 80% wool + 15% acrylic + 5% spandex) and two cutting methods (straight direction and bias direction). In the appearance evaluation results, both real and virtual skirts showed differences in their appearance depending on the fabric used. The virtual skirts appeared to spread out more widely than the real skirts, while the drape was observed to be less pronounced. Furthermore, the cross-sectional shape analysis of the skirts revealed that the draping of the real skirts appeared irregular, whereas the virtual skirts exhibited a more symmetric and regular draping shape. As a result, the virtual flared skirts were evaluated to achieve a more stable draping shape, providing a better representation of the draping compared to the real flared skirts. In the analysis of the skirts’ flatness, it was observed that the real skirts exhibited a slightly rounder shape compared to the virtual skirts, and there were no significant differences based on the cutting direction. It was observed that the virtual skirts had approximately 3 to 6 fewer nodes compared to the real skirts, resulting in an inadequate representation of the actual fabric’s drapability. Furthermore, the analysis of the maximum distance between nodes revealed that as the bending strength of the fabric increased, the maximum distance also increased. Additionally, significant differences were observed between Muslin 30s and Wool blend fabrics in terms of the maximum distance between nodes. Indeed, based on the findings, it can be concluded that there are differences between real and virtual skirts, especially when using fabrics with higher bending strength and heavier weight. These fabric properties seem to influence the draping and overall appearance of both types of skirts, leading to variations between the real and virtual representations.

This study was to compare and analyze the foot size according to sex and age group and to classify and provide adults foot types. 219 adult men and 181 adult women were randomly sampled and measured by using a one dimension direct measurement method. 1. According to the results of T-test according to sex, there was a significant difference between men and women in all measurement items. In other words, men gained an advantage over women in all measurement items. Also, according to ANOVA, no significant difference existed among age groups for men in the degree of foot metamorphosis, while there was a significant difference among age groups for women. This results illustrated that womens foot was metamorphosed more than men as they grew older (getting lower in height, wider in breadth, and bigger in girth). 2. Five factors were extracted form the factor analysis of direct measurement for each sex group. For men, five factors were size, heel, external internal, and height factor. For women, five factors were size, instep, external, and heel factor. From these results, we could identify that the size and heel factors affect foot type for men, while the size and instep factors affect foot type for women. That was, for women, there was a significant difference in instep related items as they grew older, meaning that the instep factor affect womens foot type more than other factors. 3. Mens foot type was classified into 4 types ; totally big type(18.7%), totally small type(34.2%), middle girth and high instep type(24.7%) and middle girth and low instep type(22.4%). On the other hands, womens foot type was classified into 3 types ; totally small type(40.9%), wide ball breadth and high instep type(29.8%) and narrow ball breadth and middle instep type(29.3%). Therefore, this study explicates that the shoe size specification needs to be developed based on not only foot length and foot girth but ball breadth and instep height in order to design a functional and comfortable shoe.

This study is to compare and analyze the body size of Middle-aged women group (40∼49 years old) and Ms group (25∼29 years old) and to identify any difference between the two groups in terms of jacket patters of B88 size (old size specification 66). The followings are the results of this study. 1. Although the Ms group is younger than Middle-aged women group, their body size is almost same as Middle-aged women group as they are growing stout. About 75% level of Ms group showed almost same size as Middle-aged women group in most of body part only except in waist and shoulder area. 2. When it comes to overall body shape, the Ms group tends to be tall and broad-shouldered compared to the Middle-aged women group. The waist and abdomen size of Ms group are smaller than that of the Middle-aged women group, implying that the two parts tend to be changed a lot as getting old. 3. The basic size for women's apparel applied by brands tend to be different regardless of the standard measure, KS K 0051. For example, size specification for the B85 (old size specification 55) was unlike among brands, which increases consumers confusion. 4. When analyzing pattern size difference between the two group, with the same B88 size apparel, jacket for Ms group is short in back area, shallow in armhole depth small in bust girth and shoulder length compared to that of Middle-aged women group. Based on the results from this study, we can conclude that the basic measure for the ready-made apparel is different among current brands, which makes consumers have a trouble to choose a well-fitting apparel. Since there exists a significant difference in body shape and size between the Ms group and the Middle-aged women group, the size specifications for the two different groups need to be different according to their somato-type.

The purpose of this study were to analyze the anthropometric data of feet of Korean women with aging, to categorize the women's foot shapes, and to compare the shoe size according to the foot shapes in order to provide the basic information for more comfortable shoes. Subjects of this study were 181 women over age 20. Theey were measured with the direct measurement method and the indirect measurement method, 26 items were measured from the right foot and 6 items were taken on foot outline. Factor analysis, cluster analysis, analysis of variance, post-hoc test, and cross tabs were performed for statistical analysis of the data by SPSS program. There were significant differences in height items, breadth items, girth items, and angle items by subjects' age. The older subjects' feet were wide and thick with big deformity on toes. The arch height of the older ones was low. This implicates that the degree of deformity on toes, the foot ratio, the foot girth, the foot breath and the arch height as well as the foot length are needed to be considered in developing comfortable shoes. Nine foot construction factors were extracted by the factor analysis of anthropometric measurements; foot size factor, heel and instep factor, malleolus lateralis factor, malleolus medialis factor, foot shape factor, shape of toes factor, heel height factor, big toe height factor, and intemal factor. On the basis of the cluster analysis, three different foot shapes were categorized. Type 1 was large and wide foot with little deformity on little toe. Type 2 was medium foot with defrmation of big toe, and with the lowest arch height. Type 3 was small and narrow foot with the highest arch height. Distribution of shoe size according to the foot shape was analyzed. The ball of foot breath was of wide distribution than the ball of foot girth. This implicates that girth items and breath items of the foot should be enclosed for the same foot length in the sizing system.

This study was to evaluate the fitness and the suitability of size specification of the ready made jacket for women by analysing pattern size and space between skin and clothing using 3D scanner. The results were as follows: 1. Pattern B had the lowest score and the feeling of wearing was significantly different among the given patterns even though all jacket size specification were the same. 2. Ease amount was different between each brand even though the jacket size specification was the same due to the different pattern grading rules. And increasing grading amounts were bigger in horizontal direction rather than in vertical direction. 3. We could obtain accurate a 3 dimensional figure, using 3D scanner which was very useful and more accurate than 2 dimensional data using photography method. 4. Analyzing the average space between skin and clothing of each pattern, there was no significant difference in the average space between skin and clothing among all patterns except waist part of B88 size. And analyzing the average space between skin and clothing of each measured body parts by each size, there existed a significant difference in the interscye, abdomen and hip parts.

This study was designed to examine the currently-used 3-D scanner and automatic body measuring program and to verify the usefulness of automatic body measuring program through the comparative analysis of results of direct body measuring with the automatic body measuring method using 3-D scanner for elderly women. 1. The analysis on the 3-D scanner and automatic body measuring program used in Korea showed that the 3D whole body scanner(WB4)(Cyberware Inc., USA) and Scan Worx VV2.6(Techmath Inc., Germany) had a comparatively high performance in terms of data gathering function and interchangeability between programs. 2. According to the results of comparing direct body measuring with automatic body measuring, no significant differences existed in all measurement items except back length. This result assures that the automatic body measuring is greatly reliable. In case of measuring the back length of elderly women using the automatic body measuring program, a scrupulous attention should be paid since the automatic body measuring program measures a vertical distance from back neck point to center back waist point, whileas the elderly women's back tends to be bent. 3. Comparing the Body measurement report for Elderly women(2002) with the results of this study, the measurement results in most of measurement items turned out to be similar, meaning that the results of this study can be used in body shape analysis as well as apparel production. 4. According to the somatotype analysis based on the KS K0055, the body type can be classified in the order of EN type(60.0%)-normal type, EA type(26.7%)-large hip type, and EH type(13.3%)-small hip type. According to the results of body type analysis, there was no significant differences in all measurement items except in thigh girth left, right item. 5. From the results of this study, the body measurement results acquired by using the automatic body measuring program turn out to be very useful. Especially for elderly women, however, the automatic body measuring program was disagreeable in such parts as back length, bust point width, side neck point to bust point length since the program was developed for general people not for the specific elderly women. Therefore, a special care needs to be paid when measuring those items for elderly women by using the program.

남녀 고등학생들의 성장에 따른 체격조사에 관한 연구

This study was to analyze high school students'(boys and girls) body growth rate during their high school period by looking into their three years' health record. This study bald attention to the body growth status especially when the growth rate of height turns to stagnate. Therefore, the results of this study can be used as a basic data for the apparel sizing system for high school students. The results of this study are as follows. 1. According to high school students' health records, there was a significant difference in all measurement items between boys and girls. The result shows that boy's growth rate was significantly bigger than that of girls on the average. 2. According to the height growth distribution chart, 63.9% of boys fall into the category of below 2cm growth between 16 years old and 17 years old. In case of girls, most of them(98.1%) shows below 2cm height growth during the same age period. Also, 90.4% of girls grow below 2cm during the period of 17 years old to 18 years old. 3, By comparing the average growth rate of each measurement item, it was found that there are significant differences in all measurement items for boys only except sitting height. It means that boys tend to grow steadily in terms of the height, weight and bust girth. In case of girls, the differences are apparent in the height and bust girth measurements. 4. After Spearman's correlation analysis, the order of correlation based on height was sitting height > weight > bust girth. It was found that the correlation between height item and girth item was low. 5. The fatty ratio of boys and girls were similar. Rohrer's index showed that there were many thin type in both boys and girls group due to the high correlation between height and weight. However, Vervaeck's index showed that normal type was the majority followed by thin type and fat type. 6. Based on the average of height and bust girth size, this study developed apparel sizing system for high school students as follows. M size for boys - height :170cm~175cm, bust girth :85cm~91cm. M size for girls - height :155cm~165cm, bust girth :79cm~85cm. The distribution of boys based on the proposed sizing system was M>S>L, while that of girls was M>L>S.
