This report deals with the relations between the vibration restraint and the stress-strain properties of the stretch fabrics. For this purpose, a survey was carried out about the preferences in sports-brassiere. Six experimental sports-brassieres of an equal design, but of different materials were tested for vibration using an accelerometer and a motion analyzer while the subject is jogging. 1. The results of the survey on sports-brassiere preferences are as follows; Preferable factors are simple design, shield and close adhesion of sports brassiere. Dissatisfied factors on the sports-brassiere are drooping, vibrating of the breast, itching and wetting. The B-cup-size group perceive the bigger vibration and drooping than A-cup-size. 2. The results of the wearing tests are as follow; This experiment shows the vibration restraint effects on different stretch fabrics, such as hard, medium and soft nature. There was a linear relationship between the vibration restraint and combination of different types of stretch fabrics. Among different brassiere types, the 2-layered brassiere (inner layer of high tension fabric and outer layer of lower stretch fabric) showed the least vibration. In the case of 2-lay brassiere, the wearing comfort rate was highest.

The object of this study is to perceive the discomforts of the brassiere consumers according to their age groups & weight groups. The study procedures consisted of a status quo study, a rating on fit and performance according to brassiere types. 1. The result of the status quo study are as follows. (1) The study showed that with getting age bust circumference and bust size become larger with a bigger tendency to droop. Thus older age, bigger bust circumference and size require a technically improved version of brassieres. (2) Slightly tight fit brassieres were favored over more ample ones. The hobbling areas were center front, under armpits, and shoulder strapareas in that order. 2. The results of fit rating on different brassiere types are as follows. (1) The areas affected by brassiere performance were length from side neck point to bust point (bust length), width between bust points and bust height. (2) Compared among brassiere types, the wire type proved most effective. The bigger cup size group had higher satisfactory rate and low discomfort on wearing.

The integrative Internet program was developed for the selection of optimal brassiere components according to the breast types of middle-aged women. In this program, a customer is classified into a certain group through three steps of a discriminant analysis. Three variables used in the analysis include breast volume, radii of curvature of under-breast curve, and a distance between inner breast points. Using individual data of three variables, the optimal brassiere components, i.e. brassiere cup size, curvature of front panel and wire, distance between cups, are suggested for each customer. Discrimination of breast types using only 2D measurements is also included for those who do not have easy access to a 3D measurement device.

This study analyzed the perception types of women over the age of 60 in regards to attitude and the effect of wearing brassiere. In addition, it was also to provide the basic data demand for the development of a brassiere for elderly women. Q methodology was used for this study. Analyze the data using the QUANL pc program. Type 1 was the nipple cover non-preferred type. Type 1 thought brassiere has uplifting effect, but is uncomfortable and only worn when going out. Type 2 was a function-oriented preference type. They wore a brassiere for beauty and psychological satisfaction. The brassiere push-up the breast and enhanced volume. Type 3 was the pursuit of vibration reducing and beauty type. The brassiere reduced breast vibration and kept armpits comfortable. The brassiere was worn for beauty. In the future, the actual development of brassieres for elderly women should be investigated for wearing sensation and satisfaction.

This study was performed to analyze the wearing practice and the purchasing characteristics of brassieres in order to offer basic data to produce superior brassiere and to improve the wearing comfort. The questionnaire were 146 Korean college female students. For data analysis, descriptive analysis, crosstabs, factor analysis and one-way ANOVA were used. The results were as follows, first, most subjects didn't know the sizing system of brassiere and their own breast size. So the degree of satisfaction of wearing brassiere was low than subjects who knew their own breast size. And they replied that the most unsatisfaction factor was brassiere size. Second, when subjects decided to purchase a brassiere they considered size, design, color, cost, fabric and brand and so on. Among them size and design were considered the most important. Third, the subjects who wear brassiere all day long, they considered wearing comfort and cost rather than design and collar. Therefore, the markets with brassieres would be able to segmented based on consumers' characteristics. Firth, the subjects were dissatisified at size, the taking off wire and shape modification after washing. And they requested the development of various size, fabric and cost improvement and fittness of brassieres. These results imply that to improve the wearing comfort of brassiere, it is so important to produce and develop various types of size first of all. And consumers should know size system of brassiere and their own breast size.

The purpose of this study was to research on breast shape and size to suggest a brassiere sizing chart for elderly women. For this purpose 90 elderly women aged between 55 and 69 were sampled at random to review their breast types by age group, and thereby, suggest the basic measurements and production ratio of each brassiere size in reference to KS K 0070: 1999. The collected measurement data were processed statistically using the SPSS PC/WIN program for technical statistical analysis. The results of this study can be summarized as follows; 1. Analysis of Breast Measurements To find out difference among age groups, the 90 subjects were grouped into three(Group 1 ; aged 55 to 59, Group 2 ; aged 60 to 64, Group 3 ; aged 65 to 69). The results of the comparative analysis of anthropometric data from three groups show that getting older;- Various length measurements related to the drooping degree of breast were increased. It was found that the older group in their 65-69's had more drooping breasts than their 55-59's or 60-64's counterparts. Such findings suggests that older women's drooping can be corrected by a brassiere which serves to support the breasts. 2. Suggestions on a Brassiere Sizing For the basic measurements of brassiere parts for the elderly women, the correlation between underchest circumferences and cup sizes were analyzed. 3% or higher occurrences among the whole sample elderly women were included in the brassiere sizes. thus, the under-chest measurements were set at four intervals from 75 to 95, while the cup measurements were determined also at four intervals from "AAA" to "B" sizes. The resultant 6 sizes excluding the least frequent occurrences covered 73.2% of the sample elderly women actual breast sizes. As a consequence of reviewing the production ratio of each brassiere size for the women, it was found that the brassiere size of highest production ratio was "85A" (17.4%), followed by 80A (14.5%), 85AA 90A (10.1%) and 75A (8.7%) in their order.

The object of this study is to develope an improved version of brassiere with better fit and improved performance by conducting a try-on test on 6 types of revised brassieres (constructed on above basis). The study procedures consisted of a try-on test of experimentally constructed brassieres and a sensory test on fit. The results of experimentally constructed brassiere trial are as follows. 1. The sizes showing performance effects due to different types of experimentally construct- ed brassieres were bust length, bust height, under bust curve length, vertical and horizontal bust diamenter, upper-lower bust slope angle (direct measurement, parallel standard, upper torso tilt rate), side bust slope angle and top bust slope angle. 2. Concerning the changes in lower cup interior, elastic materials and wider portions perfor-med better in bust up effect. 3. No effects due to different shoulder strap positions were observed, but combined with lower cup interior changes the side types proved more effective than the standard types.

The purpose of this study is to investigate the visual sensibilities of brassiere design. Brassieres were divided into three types according to connection of a cup and a strp. In each type Lace was used where the part of the cup divided by Lines which were constructed such as a mold a horizontal a vertical a mixed and an oblique design. As a result 39 brassieres were obtained. The experiment has been done for seven groups which were divided by the type line and lace with 5 semantic differential bi-polar scales and 10 specialists. The data was analyzed using the statistical SPSS package. The major findings of this research were as follows. An oblique design line in the brassiere were effective in making the breast look bigger more buxom and more voluminous. To make the breast look small and unvoluminous the use of a mold in the 1/2 cup brassiere was effective. Also a mold using lace ion the 1/2 cup brassiere had an effect in making the breast look flatter and broader.
