The optical method Digital Speckle Correlation Measurement (DSCM) has been extensively applied due its capability to measure the entire displacement field over a body surface. A formula of displacement measurement errors by the gradient-based DSCM method was derived. The errors were found to explicitly relate to the image grayscale errors consisting of sub-pixel interpolation algorithm errors, image noise, and subset deformation mismatch at each point of the subset. A power-law dependence of the standard deviation of displacement measurement errors on the subset size was established when the subset deformation was rigid body translation and random image noise was dominant and it was confirmed by both the numerical and experimental results. In a gradient-based algorithm the basic assumption is rigid body translation of the interrogated subsets, however, this is in contradiction to the real circumstances where strains exist. Numerical and experimental results also indicated that, subset shape function mismatch was dominant when the order of the assumed subset shape function was lower than that of the actual subset deformation field and the power-law dependence clearly broke down. The power-law relationship further leads to a simple criterion for choosing a suitable subset size, image quality, sub-pixel algorithm, and subset shape function for DSCM.

The purpose of this study is to investigate how the shape of the lower body influences an individuals' ease in fitting skirts. Subjects in this study consisted of 188 adult females categorized into two groups(the first group were subjects 18∼33 years of age and the second group 34∼59 years of age), whose measurements were taken and then compared between the two groups. The subjects were also categorized into 5 different lower body types. The following are the results; (1) The comparative analysis of the ease from the two a9e groups showed a bigger value of waist girth in the young age group. And thereverse results were found when measuring hip firth. (2) The correlation analysis between the ease and the anthropometric data showed a weak statistical correlation in the older group, and showed no statistical correlation in the younger group. However, there was correlation between the ease and the body measurements as well as between the differences of waist girth and hip girth. (3) The most appropriate average ease of skirt in the young age group was 1.03 cm for waist and 5.71 cm for hip; the most appropriate average ease of skirt in the older age group was -0.76 cm at the waist and 4.10 cm at the hip. (4) Analysis of variance with a special emphasis on the ease of waist girth and hip girth according to the anthropometric data of the lower body revealed a statistically significant correlation.

The purpose of this study is to analyze the perceptions of obesity among appearance-conscious women in their 20s. It is intended to provide data necessary to produce garments for obese body types by identifying adult women's subjective assessments of obese body types and characteristics. The data were analyzed using Q Methodology in the QUANL program for PC. Type 1 was recognized as uniformly fat in the abdomen, with almost the same width and thickness. Type 2 was perceived to have more fat in the upper body and back, broad shoulders, and an inverted body type. Type 3 was perceived as having a fat lower half of the body, hips wider than the chest, and large thighs. Type 4 was identified as having few curves and fat concentrated in the abdomen. Further research of other age groups and regions is needed to ascertain the difference between perceived and actual body types.

The purpose of this study was to identify the body shape satisfaction and body shape esteem according to the state of obesity in elementary school students. The data were collected from May 1st to 31th, 1999 using the questionnaire and the physical examination record. The subjects were 669 in 12-year old children. Data were analyzed with frequency, percentages, crosstabs, ANOVA, pearson correlation using the SPSS program. The results were as follows: 1. The prevalence of overweight was 14.0% of total students, 21.4% of mail students and 6.6 % of female students. 2. There were significant differences in the body shape satisfaction according to the state of obesity in total students(($chi^2$ = 110.31, p = .000), in mail students(($chi^2$ = 99.97, p = .000), in female students(($chi^2$ = 62.23, p = .000). The percentages of the body shape satisfaction were highest the underweight group in total and female students but in mail students the normal weight group was highest 3. There were significant differences in the body shape esteem according to the state of obesity in total students(F = 8.634, p = .000), in mail students(F = 11.738, p = .000), in female students(F = 4.502, p = .004). The mean scores of body shape esteem were highest the normal weight group in total students, overweight group in mail students and underweight group in female students. The higher the state of obesity was, the lower body shape esteem. 4. The relationships between body shape satisfaction, body shape esteem and obesity index were significant. Obesity index were significantly and negatively related to body shape satisfaction(r = -.2081, P = .000), to body shape esteem(r = -.2250, p = .000). 5. There were significant differences in the state of obesity according to sex(($chi^2$ = 88.136, p = .000) and the perception of body shape(($chi^2$ = 242.371, p = .000) in total students. There were significant differences in the state of obesity according to the body shape of father(($chi^2$ = 15.11, p = .019), the perception of body shape(($chi^2$ = 138.95, p = .000) in mail students. There were significant differences in the state of obesity according to the education of mother(($chi^2$ = 19.46, p = .022), the perception of body shape(($chi^2$ = 143.35, p = .000) in female students.

The purpose of this study was to classify the upper torso body types of obese Korean adult women using the 7th Korea National Anthropometric Study data and compare the body type differences according to three age groups: 20s~30s, 40s~50s, and 60s. A total of 548 adult women whose BMI was in the obese range of 25 or higher and whose age ranged from 20s to 60s were selected from the anthropometric database. Twenty-nine body measurements related to torso and arm areas important for torso and sleeve pattern development were chosen. Five drop values by differences between bust, waist, and hip circumferences were also chosen for analysis. The number of obese women increased with age. The results revealed seven factors according to the factor analysis and three obese body types based on the cluster analysis. Body type 1 (47.3% of obese women) was characterized by narrow shoulders, a small or medium torso, and a straight waist. Body type 2 (42.4% of obese women) was characterized by a defined waist and a larger lower torso than upper torso. Body type 3 (10.3% of obese women), the largest obese body type among the three types, was characterized by a large bust, large abdomen area, and long upper torso. Women in their 20s to 30s were most likely to have body type 2, women in their 40s to 50s were evenly distributed between body types 2 and 3, and women in their 60s were most likely to have body type 1.

This study surveyed some general fit problem of the ready-to-wear slacks of women in 20＇s. A questionnaire survey was administered to 80 women in 20＇s. 14 body dimensions were measured fer 53 women among the subjects who participated in this survey. Their anthropometric data were analyzed and the difference between actual and perceived body shape was compared. The results of this study showed that the subjects experienced poor slacks fit at thigh, crotch, and hip areas. Occasionally subjects altered the waist size of slacks after purchasing them. Despite the subjects＇ waist measurement was ranged from 22 to 33 inches, most of them purchased slacks with size 26 or 27 inches. The researchers claimed that the manufacturers did not provide various slacks sizes for women in 20＇s. The subjects, who had problems with poor slacks ft, preferred to buy customized slacks. The most of subjects preferred to buy mass customized slacks to have chance to choose their own style from pool of various styles. The subjects tended to perceive their body size larger than actual at hip and thigh. The most critical body dimension reflected their perception on lower body fitness was waist circumference.

This study analyzed the relationships among actual body types, perceived body types, body-image discrepancy(difference between perceived and ideal body), and body satisfaction, and their effects on jacket fit satisfaction at 17 body parts of women in their 20s. To apprehend the actual body type of subjects, total 18 items were measured according to the anthropometric method of the 6th anthropometric survey project. The relationship between body-image discrepancy and body satisfaction was correlated in all body parts. Body-image discrepancy and body satisfaction were more affected by perceived body size than actual body size. The fit satisfaction level of the jacket was found to be lower as the discrepancy between the body type and the ideal body type was recognized. As the waist girth, hip girth, armscye girth, and upper arm girth were smaller, the height was taller, bust girth and breast size were larger, these body sizes were considered as closer to the ideal body shape and the jacket fit of the area was more satisfied. When the perceived body sizes and the actual body sizes were compared, the women in their 20s tended to perceive their waist, abdomen, and hip as larger, their shoulder length and front/back interscye as longer, their breast size as smaller, and their waist height as lower than the actual size.

The purpose of this study was to make a pants pattern suitable for women 70 to 85 years of age, then analyze that- pattern's shape, size, appearance, fit, allowance and air gap. Participants made the pattern using 3D simulation program DC Suite version 5.1. The results suggest a design method suitable for the lower-body shapes of elderly women. In external appearance, the A-type earned the highest evaluation in all items except the allowance of the back waist and back hip. The L type earned the highest evaluation in the allowance of back waist and hips. The A-type's, back waist appeared set at an angle that did not match the body shape of an old-old aged woman in the center-back-line setting. Therefore, the pattern method of A-type combined with L-type's method of center back, produces an excellent pants pattern. Evaluation of the air gaps among patterns revealed that; the A-type showed the largest air gap in waist and hip circumference and the smallest air gap in thigh circumference. The waists, abdomen, and hip circumferences of older women often become larger while their legs become slimmer. This study accounted for those factors in determining a pattern suitable for the lower-body shape of old-old aged women. However, participants only analyzed four patterns and compared them with women 70 to 85, years of age. Therefore, it is necessary to develop industrial patterns applicable to a wide age group.

To give satisfaction with the fit to a wearer, the wearer's body size and body types should be considered first, this study conducted the descriptive statistical analysis on the upper body measurements of women in their 20s because their body shape has reached the completion stage of adult female's physical development. Also, the analysis classified their upper body types into groups to secure basic data for (maximum satisfaction with the fit of ready-to-wear clothing. The factor analysis was conducted using 49 items of measurement. The main factor analysis was used as a factor extraction method. After extracting the factors with Eigenevalues over 1, the factor loadings were drawn using the Varimax rotation. As a result, 6 factors were extracted. To secure internal consistency, factors that could lower the reliability of the experiment were taken out, so only 36 of the 49 items were used for the analysis. After selecting the items to recognize the main features of each body type, they were used for the final factor analysis. The entire R square of the 6 factors was 84.06%. To classify the upper body types of women in their 20s and to recognize the main features of each body shape type, the researcher conducted the cluster analysis with the items generated from the factor analysis. Through the cluster analysis, the upper body type of women in their 20s were classified into 3 body types. Also, since there are some restrictions on this research objects in terms of local and numbers of measured objects, the results of the this research should only be used as basic data.
