여대생의 체형별 신체만족도와 의복이미지 연구

To find the differences between the real somatotype and the ideal somatotype, WHR(Waist to Hip Ratio), WCR(Waist to Chest Ratio), and body cathexis were analysed by using ANOVA test, Duncan`s multiple range test, and test. Fashion image sought by female collegians was surveyed, too. The results were as follows. WHRs in slim, usual, fat body type were 0.75, 0.76, and 0.83 and WCRs were 0.77, 0.81, 0.80. The respondents who considered themselves to be overweight recognized themselves to be fatter than their real weight. They were not satisfied with their bust girth in slim body type, thighs and calves in usual body type, and all parts except for foot length, hand length and arm length in fat body type. 60% of the thin people considered their body hourglass shape, 30.4% of regular people recognized their body triangle type, 43.8% of fat people thought their body was round form. They thought current ideal body size was bigger in height and bust girth and smaller in waist girth and hip girth, and weight than real body size. Also they responded ideal body shape was an hourglass type independent of somatotype. The pursuit of clothing image was that 45.5% of female collegians were fashionable and raffine and 10.4% of female collegians was elegant and graceful. Among the body area, body parts that may have an effect on body image were body length in 13.1% of the respondents, waist girth in 10.7% of the respondents, and hip girth in 10.0% of the respondents.

중년 비만여성을 위한 수영복 치수규격 제안

Abstract This study helps out-size consumers purchase swimsuits and improves fitness by classifying the torso ofmiddle-aged obese women; in addition, it creates a size system based on each size interval for obese types.The criteria for subjects in this study were over 25kg/m 2 of the BMI, over 85cm of waist, and over 95cmof bust; 199 females were surveyed. Three torso types were categorized by a cluster analysis into X type(the vertical size of hip girth was the biggest of the three and the waist was slender), H-O type (larger thanother groups in bust girth with more fat above the circumstance of the abdomen), and Y type (the upperhalf of body development type and lower body fatness were between those of type X and those of type H-O). As a consequence of size system establishment according to obesity types, the basic body sizes andreference body sizes were different according to types even in commonly-appeared size names at sectionsof respective types. The research findings show the necessity to understand obesity types according to bustgirth and hip girth sizes that represent basic sizes as well as to design patterns in consideration of thecharacteristics of obese body shapes when swimsuits are designed for obese groups. The findings can beused as basic data to decide the desirable output of production according to respective body types.Key words: Swimsuit, Size-designation, Size-interval, Drop-value; 수영복, 치수규격, 치수간격, 드롭치

The aim of this study is to develop clothing size system according to each size interval for obese girls aged 10~12 by classifying the upper bodies. The criteria for subjects in this study were girls who had over 1.46 of the R<TEX>$\ddot{o}$</TEX>hrer Index. A total of 229 schoolgirls who met these criteria were enrolled. Results are as follows; 1st, 5 factors were extracted by factor analysis and 3 clusters were categorized by cluster analysis, cylinder-type, inverted triangle-type and inverted trapezoid-type. And 2nd, as a consequence of size system establishment, the basic body sizes and reference body sizes were different according to types even in commonly-appeared size names at sections of respective types. The research findings above suggest that it is necessary to figure out the obesity types according to height and bust girth sizes representing basic sizes and to design the patterns in consideration of the characteristics of obese body shapes. And it may be used as a basic data to decide the desirable output of production according to respective body types.

비신축성 코르셋의 의복압으로 인한 생리적 반응의 변화

The purpose of this study is to analyze the physiological effects of non-elastic corset on women's health and pain through measuring the clothing pressure, subjective pressure sensation, blood velocity and metabolism. 5 women in their twenties were picked as our subjects, their average size being 85cm at bust girth, 69 cm at waist girth. With the subjects each wearing a corset, we are testing in artificial environment with a treadmill according to the planned exercise procedures. The average pressure of the corset is 0.938 kPa (maximum 3.006 kPa at 45 degree front bowing), which is 10.2 times higher than the control group, averaging from 9.3 times higher at resting, 11.4 times at walking, 11.1 times at running. The effect of corset pressure on the physiological responses of the body is increased more when exercise than when resting. Clothing pressure increased in the order of the postures: sitting > standing with 45 degree bowing > standing. They experienced a high level of tighten discomfort of 5.6 in the scale of 1.0 to 7.0 due to the high pressure of the corset when resting, after intense exercise the level increased to 6.0, while without corset the level increased 1.7 to 2.2. With corset on, the blood circulation did not increase even though when the body exercised and blood flow became unbalanced making great gaps between both at the right and left finger tips. Perspiration of chest and back decreased 37.3% when wearing corset; 27.5% at resting, 56.7% at walking, 25.8% at running, and 39.0% at recovery. With corset on oxygen consume and metabolism increased 9.0%, 7.9%, respectively, which means the corset makes the body uncomfortable. Lung volume exchange VE decreased almost 4.1~7.3% with corset on and <TEX>$VCO_2/VO_2$</TEX>, RER and total volume in lung, VT also decreased too, which means the digestion of stomach and lung function are inhibited due to the high corset pressure.

3-D breast anthropometry of plus-sized women in South Africa

Exploratory retail studies in South Africa indicate that plus-sized women experience problems and dissatisfaction with poorly fitting bras. The lack of 3-D anthropometric studies for the plus-size women's bra market initiated this research. 3-D body torso measurements were collected from a convenience sample of 176 plus-sized women in South Africa. 3-D breast measurements extracted from the TC2 NX12–3-D body scanner ‘breast module’ software were compared with traditional tape measurements. Regression equations show that the two methods of measurement were highly correlated although, on average, the bra cup size determining factor ‘bust minus underbust’ obtained from the 3-D method is approximately 11% smaller than that of the manual method. It was concluded that the total bust volume correlated with the quadrant volume (r = 0.81), cup length, bust length and bust prominence, should be selected as the overall measure of bust size and not the traditional bust girth and the underbust measurement. Statement of Relevance: This study contributes new data and adds to the knowledge base of anthropometry and consumer ergonomics on bra fit and support, published in this, the Ergonomics Journal, by Chen et al. (2010) on bra fit and White et al. (2009) on breast support during overground running.

A study of the relationship between clothing pressure and garment bust strain, and Young’s modulus of fabric, based on a finite element model

In an effort to provide a technology platform for the mechanical analysis of the clothing pressure on the bust and to investigate the relationship of clothing pressure on the bust and garment bust strain, and Young’s modulus of fabric, accurately, a finite element model of the standard female body bust cross-section was created. The model was composed of skin, soft tissue and bone. The clothing pressure exerted on the busts by 10 elastic sports vests of two types of extensibility in fabric with different bust girth and identical style was measured, then the pressure was taken as load and applied to the model. The bust strain of 10 sports vests after wearing was calculated based on the finite element model. The data from eight out of the 10 vests was chosen to find the linear equation of the relationship between the clothing pressure exerted on the bust, the vest bust strain and Young’s modulus of fabric. The data from the other two vests were used to verify the equation, and results indicated that the calculated clothing pressure was very similar to that measured, proving that the equation can provide a database for the design, from bust size, of functional pressure comfort tight-fit garments.

Classification of body shape characteristics of women's torsos using angles

PurposeThe purpose of this paper is to classify body shapes using angular defects instead of sizes.Design/methodology/approachA large amount of dimensional data from a national anthropometry survey was analysed, and a basic pattern and its polyhedron were also used to create a three‐dimensional body shape from three body sizes. Using this method, the sizes were converted into nine angular defects.FindingsThe authors could define the factors explaining body shape characteristics and classify the body shapes into four groups. The four groups could be characterised by two pattern making difficulties of the upper and lower parts of the body as well as by two proportions, of waist girth to bust girth and bust girth to back length. Furthermore, depending on the age, the authors could understand body shape by the angle made.Originality/valueUsing a polyhedron model, the angles could be calculated using an enormous existing data set of sizes. An angular defect serves as an index to indicate the degree of difficulty for developing a flat pattern. If an angular defect of the bust is large, it is difficult to make a paper pattern of a bust dart. On the other hand, if an angular defect of the waist is large, it is easy to make a paper pattern of a waist dart. Thus, each body shape could be simultaneously characterized by two difficulty indices and two proportions of sizes.

비만여성의 의복치수체계 연구

본 연구는 20세 이상 비만여성을 위한 의류치수체계를 제안하기 위한 것으로, 2003~2004년 한국인 인체치수조사사업의 원시자료 중 선행연구에 의해 의류학 분야에서 주로 사용되는 비만판정지수 및 비만판정용 측정치 7개 항목(Rohrer지수, Vervaeck지수, BMI, 상대체중, 허리둘레, WHR, 젖가슴둘레) 중 5개 이상의 비만판정도구에서 비만으로 판정된 499명을 대상으로 하였다. 연구의 결과는 다음과 같다. 치수체계 제안에 앞서 2,212명의 성인여성 전체의 인체치수와 499명의 비만여성의 기초통계치수를 제시한 결과, 키 등의 높이항목 전체와 키와 상관관계가 높은 몇몇 길이항목을 제외한 대부분의 치수항목 즉, 둘레항 목, 두께 및 너비항목 등에서의 인체측정치가 크고, 비만판정지수도 높은 것으로 나타났다. 상의류의 치수체계 제안을 위해 젖가슴둘레, 엉덩이둘레, 키가 기본신체부위로 선정되었으며, 하의류의 치수체계 제안을 위해 허리둘레와 엉덩이둘레가 기본신체부위로 선정되었다. 치수체계 제안을 위한 교차분석표에서 젖가슴둘레, 허리둘레, 엉덩이둘레 등 둘레항목은 3cm 간격과 5cm 간격을 비교하여 제시하였으나 키는 5cm 간격으로만 한정하였다. 두 치수간격 중 보다 높은 커버율과 커버효율을 보이는 치수간격을 선택하고, 사용자의 분포율도 전체 비만여성의 1% 이상, 2% 이상 및 3% 이상으로 나누어 각각의 분포율별로 커버율과 커버효율이 높은 치수구간을 선정하였다. 상의류와 하의류 치수체계 모두에서 3% 이상의 사용자 분포율을 보이는 5cm 치수간격이 가장 높은 커버효율을 나타냈으므로, 이 결과를 바탕으로 상의류를 위한 치수호칭으로 10개, 하의류를 위한 치수호칭으로 9개를 제안하였으며, 각 호칭별로 기본신체부위의 평균 인체측정치와 참고신체부위의 평균 인체측정치를 제공하여 호칭별 의류제품의 설계에 기초자료로 활용할 수 있도록 하였다. This study suggests apparel sizing systems for obese women in their twenties to fifties. Size Korea body measurement data were used for sampling the obese subjects by obesity judgment indices. A total of 7 obesity judgment indices frequently used in the clothing field were inspected and the measurement data of 499 females defined as "obese" by over 5 obesity judgment indices were analyzed. The results of the study were as follows: A total of 2,212 female body measurement data for the Size Korea Project were collected. These were compared with the 499 data of the obese women in the study. Except for all heights and some lengths correlating with heights, the measurements of obese women were larger than the entire group of females. Bust girth, hip girth, and height were selected as control dimensions of the outerwear covering the upper body; waist girth and hip girth were selected as control dimensions of the outerwear covering the lower body. In each crosstabulation table, 3cm pitches and 5cm pitches by bust girth, waist girth, and hip girth were compared in the aspects of coverage and coverage efficiency. Finally, sizing charts for outerwear covering the upper body and the lower body of obese women were established in the study through the comparison of the coverage and the coverage efficiency. These Size charts were given by 5cm pitches as final sizing systems. Size number of outerwear covering the upper body was 10 and size number of outerwear covering the lower body was 9. In addition, the body measurements of control dimensions and referable dimensions for making garments are given.

여대생의 브래지어 착용과 선호에 관한 연구

To provide basic data to manufacture superior brassieres, we performed a survey on the wearing and buying habits, and preference of functions and materials of brassieres for 189 women subjects in their twenties. The results of this research are as follows; Style and size are the most important in purchasing brassieres. Flat breasted and sagging breasted subjects were dissatisfied in the fit of the upper cup. 70% of the subjects were ignorant of their brassiere size. Sagging breasted subjects were less satisfied with smoothness, softness, and weight when wearing their bras in comparison with the other types. Conical type breasts were common amongst women in their 20s. They are more likely to wear size 75A and 80A where the full bust girth is 10cm larger than the under-bust. They preferred demi cup brassieres with thin or moderate padding to full cup brassieres with thick padding. On the other hand, 56.8% of subjects wore brassieres all day. The subjects were dissatisfied with the slipping down of the shoulder straps. Large-breasted subjects were concerned more with dampness and the fit on the center front of the brassiere, and brassieres with too thick padding had a poor fit on the center front. Sports-brassieres which fit close to the skin and used stretchable fabric caused more itching and dampness and dissatisfaction in removal of the brassiere.

This research was to develop Taekwondo trunk protector(Hogu) and head protector's sizing systems corresponding the regulations by World Taekwondo Association. These sizing systems were established using 2003-2004 Size Korea anthropometric data. The result can be summarized as follows: According to the analysis of correlation, most measurements had high relationship with weight for Hogu and head girth for head protector. Six sizes(47, 54, 59, 64, 70, 76) for Hogu and 4 sizes(52, 54, 56, 60) for head protector were suggested in this study. Hogu sizes indicate body weights and head protector sizes express head girth measurements. By the comparison between current Hogu sizes and new sizes, the smaller sizes of new Hogu were bigger than current sizes in bust girth, back fastening length, shoulder length. On the other hand, the bigger sizes of new Hogu were larger than current sizes in bust girth, back fastening length, shoulder length. In addition, new Hogu's lengths were shorter than current Hogu in all sizes. The lengths of Neck to collar bone in new Hogu sizes were longer than current Hogu. In case of the head protector, there were no measurements besides outer circumference of helmet in recognized specifications of WTF. Therefore some referable measurements such as head girth, head length, bitragion arc, sagital arc were suggested in new size specification. When helmet sizes were suggested, the thickness of the NBR foam also were considered.

Age‐variability in Body Shape Associated With Excess Weight: The UK National Sizing Survey

The health risks of obesity are disproportionately due to central abdominal adiposity; however, the extent to which age is associated with the body shape of obese adults is not known. Three-dimensional (3D) data on body shape from the UK National Sizing Survey were analyzed to investigate age-associated changes in body shape within the BMI bands <20, 20-24.99, 25-29.99 and > or =30 kg/m(2). Measurements of anthropometry (weight and height) and a 3D body scan were obtained in 4,344 men and 5,266 women recruited from eight British cities. The body shape of men showed high consistency within BMI bands between early adulthood and old age. In contrast, the body shape of women altered within each BMI band with increasing age. In obese, overweight, and normal weight women, age was associated with decreased thigh girth, increased waist, and bust girth. Whereas young obese women maintained an hourglass shape, in old age the body shape of obese women converged on that of obese men. The association of age with body shape is markedly different between the sexes, with the impact of obesity on shape strongly age-dependent in women but not in men. The age delay in the association between obesity and high waist girth in women may contribute to the sex-difference in life expectancy. The relationship between body shape change and cardiovascular risk merits longitudinal investigation within individuals.

Development of a new chinese bra sizing system based on breast anthropometric measurements

Since 1935, the bra sizing system has been based on bust girth and underbust girth. Woman's breast is however a very complex 3D geometry, the existing sizing system based on just two girth measurements may be inappropriate in the categorization of breast sizes for bras. Through analyzing the nude breast measurements from 456 subjects aged between 20 and 39, we hereby propose a new bra sizing system for Chinese women. The new sizing system uses underbust girth and the breast depth width ratio as the classifying parameters. They were identified through principal component factor analysis and K-means cluster analysis as the two most critical parameters out of 98 measurements obtained from 3D body scanning and 5 supplementary manual measurements as well as other relevant breast parameters including breast angles, distance, width, thickness, volume and curvature. Relevance to industry The existing bra sizing system is inadequate in classifying breast sizes for bras. This paper presents a method for classifying nude breast shape for establishing a new bra sizing system. The application of the new sizing system will be important to improve fitting comfort in intimate apparel.

The propose of this study is to develop the optimal sizing system of ready-to-wear far elementary school boys using a newly invented statistical technique. The body measurements was classified by the method that equalizes the distribution of the subjects using the probability density function, to theoretically systemize a method to determine a size range of ready-to-wear for elementary school boys between 7 to 12 yeiws old. The results were as follows: 1. Height group includes 9 types of heights: 115, 120, 125, 130, 135, 140, 145, 150 and 155. 2. In the case of short children`s groups, the variance in bust girth and waist girth is narrow. The people cluster together around the average. The size deviation of ready-to-wear is small. 3. In the case of tall children`s groups, the variance in bust girth and waist girth is wide. The people spread widely around the average. The size deviation of ready-to-wear is large. 4. The optimal size system is suggested considering the weight of growth exponent of children according to their respective ages. Clothing companies can selectively choose sizes that meet the target of their brands. 5. It suggests the body sizes chart, which based on their means by the middle size children for each height group, so that clothing companies make use of it.

Garment Sizes Analysis on Target Ages and Body Shapes

This study was performed to narrow down the Sizing System for Female Adult's garments(KS K 0051) following age target and body shapes. The study was based on the sizing system and the anthropometric measurements, called Size-Korea, which were surveyed in the years 2003 and 2004. At first, the subjects of the survey were classified into 4 age groups, , based on the most significant differences of body sizes. Secondly, the ranges of four key dimensions - height, bust, waist and hip-of normal sizes were identified through analyzing Rohrer index and percentile. The selected sizes within the ranges were grouped by the drop which was the subtraction of bust girth from hip girth. In conclusion, there was the most frequent drop for each age group; 9cm drop for the years old group, the 6cm drop for the years old and years old and 3cm drop for years old. The upper body garment sizes of the same drop and target ages could be merged to 10 to 12 sizes, which were remarkably smaller than the Female Adult garment sizing system, and further to 2-5 sizes, considering the percentile importance. However, years old group needed to be analyzed in different ways, because the number of subjects of normal size in the age decreased rapidly, that the normal sizes for them were very limited. In addition, the reference body sizes of each garment size were apparently different when they were compared to each age groups. These basic data for garment size specification could be usefully adapted for the apparel companies' own sizing system according to their age target and body shapes, to achieve efficient production and better fit.

Anthropometric Data Application in Product Design

Anthropometric data are collected and used by all types of organizations for many types of applications. These including universities, hospitals, health statistics departments, militaries, apparel companies, furniture manufacturers, automobile manufacturers, safety equipment companies, aerospace companies, and many other industries and organizations. This paper was performed to summarizes some of the objective data to get the comparison of the body shape between generations. Height, bust girth, waist girth and hip girth were used to define the body size shape. Whole data were obtained from sixty families. Height in young female from the 2002 measurement data showed greater values 3cm in young aged women from 1997 measurement data. For the drop values between hip girth and bust girth, the results were 7cm in twenties, 4cm in fifties. This paper also will discuss some of the most important issues, how family models were changed, and any changes in how we would do this study if we were to do it over again.

This study was initiated to develop a methodology for devising Korean virtual models for apparel shopping at internet shopping site. The data base for this study was the Korean National Anthropometric Survey in 1997. The subjects were 493 women and 626 men in 20's. The researchers also measured 88 males and females in age 20's to suggest back and front depth proportions which are not available from the survey. The virtual models' figure types were classified by the heights, drop value and bust(chest) girth. It was evaluated whether it is needed to separate figure type with bust(chest) girth. The body sizes of virtual models were suggested for side view model and front view model in 13cm height. Four female virtual models were suggested for front view and side view. Eight male virtual models were suggested for front view and side view. Each virtual model's height, breadth and depth proportions were calculated. Shoulder breadth. Bust(chest) breadth, waist breadth, hip breadth and proportions were calculated for front view model. The bust(chest) depth, waist depth, abdomen depth, hip depth and proportions were calculated for side view model. Height proportions were suggested for female and male virtual models.

Garment‐sizing Systems: An International Comparison

Reviews the sizing systems developed in several countries — the USA, Austria, England, Germany, Hungary, Japan and South Korea. A comparison of these systems shows that: the way of labelling garment sizes has varied from one sizing system to another; most of the sizing systems classified figure types by height and drop value (the difference between hip girth and bust girth measurements), and the way of classifying garments and the key dimensions of garment types in each system was slightly different. Recognizing the need for greater uniformity, the International Organization for Standardization (ISO) developed an international size labelling system. Many countries, including England, Japan, South Korea and Hungary, revised their size labelling systems by adopting the ISO system.
