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.

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.

A breast model was for the human body was devised by studying a body scan and human body index of a desirable breast type. Thus, when manufacturing various 3D models, these results can accordingly become a fundamental basis for realizing a desirable breast model. This study aims to provide a basic data for designing the cup patterns of brassieres in order to improve the function and wearing comfort. The comfort of three kinds of brassieres were compared: one manufactured by the actual measured size; another manufactured as per the ratio of desirable upper and lower breast lengths; and the third manufactured by the 3D model attained by the desirable human body ratio. In this study, we suggest a process for realizing the desirable breast model using the ratio of bust breadth and waist front length, which are the components for deciding the appropriate position and size of breast, and which are easy to measure. The ideal breast shape is an equilateral triangle formed by connecting the nipple with the center of the clavicle. After deciding the interval between the nipples, this value can be used to configure the locations of nipples by drawing a tangent, with equal length, from the anterior neck point (which is the center of clavicle) to the nipple. Also, since inside points of breast do not exist, the outer point of breast, upper point of breast, and below point of breast on the same plane, and the depths from the nipple point to the respective points, are applied to simulate a 3D image, by modifications along the x, y, and z axes. Depending on the type of breast, the length from the center of shoulder to the nipple, the diameter of breast, upper length of breast, and the position of nipple, are different. In conical or protruding breast, the wearing sensation is better when the nipple point of brassiere was lifted, by modifying the upper and lower lengths of breast. Considering the wearing sensation and function of a brassiere, it was better to leave the wearer's size as it is and use a pad within the same cup, rather than increase the basal area of the breast in order to increase the volume.

The breast types of middle-aged women of 80A (formerly 80B) size were classified through a 3D scanned nude body. Thirty seven measurements including the radius of curvature, surface area, volume, surface length, and breast displacements were used as input variables. We extracted five main factors through the factor analysis of the measurements and classified 36 subjects into 3 clusters through the cluster analysis. As a result of the factor analysis, the size of the breast, breast sag, the curvature of the inner and the outer breast curve, the width of the breast, and the nipple direction were found as the main factors. For the results of the classification of breast types, Cluster 1 was characterized by narrow breast width and unsymmetrical under the breast curve, whereas Cluster 2 was a wide and sagged shape. Cluster 3 was classified into big breast volume and symmetrical under-breast curve. The results are useful to the product development of high quality brassieres which reflect the 3D characteristics of breast types of middle-aged women.

This study looks into the appearances and contents of undercloths advertisements by analyzing them appeared in women\`s magazines of Korea, which are , and published between 1965 and 1999 mainly targeting the women at the age of 20s through 40s. This study leads to the following conclusions : 1. Most of advertisements use 1 or 2 pages of the magazines with colored pictures. 2. The most frequently advertised underclothes is brassieres and white and pastel are dominant colors. Also, spandex and cotton are the most frequently appeared fabrics in the advertisement. 3. Professional Korean female models in twenties are the most favored choice for those underclothes advertisements and those models dominantly face their fore part with showing the body parts higher than their knees. Solo model appear in most of the advertisements and independent appearance is dominant. 4. In the visual expression of the advertisements explicitly show the products for visual expression, whereas verbal expressions mostly emphasize the benefits to be obtained from the underclothes advertised. 5. Advertisement appeals are mainly base on readers\` reason rather than sensibility.

We studied on the development of clothing pressure measurement system for wear comfort of foundations(girdle, brassiere, all-in-one). Measurements of clothing pressure were made on subjects wearing girdles, brassieres, all-in-ones of several type(material, size) using by CPMS(clothing pressure measurement system: Tech-Storm. Co). Wearing experiments have been carried out using nine women in the twenties and six women in the forties. The results obtained are as follows: 1. The clothing pressure applied by girdle was higher in the hard type than the soft type by $5-10gf/cm^2$, also recorded a high clothing pressure at points of waist band line and thigh lateral. 2. Clothing pressure of brassiere with wire was high at the point of underbust line and shoulder strap. Pressure for 40s showed higher than 20s by $6-7gf/cm^2$. 3. The pressures of abdominal part applied by both of girdle and all-in-one were much greater than those of girdle or all-in-one. 4. We demonstrated the adaptability and conformity of the CPMS by inquiring into the clothing pressure of various foundations.

A Study on the Development of Brassiere Pattern for Elderly Women The purpose of this study is to develop functional and sensible brassiere for elderly women. For this purpose, 6 elderly women(aged between 65 and 69) were sampled to be measured for their body sizes and tested for their bressiere wearing. he results were as follows; 1. In order to develop the basic patterns of elderly women's bressieres, 90B size was selected and then, their bressiere fitting was tested. The foundation pattern of the size 90A was proved for the body by the wearing tests. Each angle and length of the parts on the basic line of the breasts played an important role on setting the pattern. 2. As based on the body surface shell extracted from a plastic mold(photo.2), the cup of brassiere pattern were applied to the body surface shell(photo.4), and full side stretch-wings were applied to 13% reduced body size. The design pattern of elderly women's brassiers were characterized by a round wired as well as a full cup(3piece) embracing the entire breasts. 3. As the result of the wearing test, the excellence of the experimental brassiere was recognized objectively, with high marks in all the items(fig. 6). The experimental brassiere was covering the whole breasts to cope with change according to breasts loosing. It was designed to support the breasts firmly.

The wearing of the correction bra is very important to stabilize the shape of an implant after breast enlargement surgery; however, the verification of the wearing effect is insufficient. This study surveyed women who experienced breast augmentation surgery, to investigate wearing condition and satisfaction with bras worn immediately after surgery and during the recovery period as well as to collect basic data for the development of an improved patient bra. The study results are as follows. More than half of the respondents stated that they wear a cupless brassiere. As a result of the satisfaction by brassiere types, the cupless bra showed the highest satisfaction. The most important factor in choosing a patient's bra after breast augmentation surgery was the "degree of breast compression". Through the application of the results of this study, the necessity of development of the brassiere for breast enlargement patients with improved function and comfort was understood. It is therefore necessary to improve the function of holding the shape of the breast and applying appropriate pressure as well as designing the ventilated material without skin irritation that is superior to the existing brassieres.

This study was peformed to establish the standard size system to be required for the production of brassiere. The subject were 155 Korean twenties-aged women and were directly measured anthropometrically. From 27 measurements, 5 factors were extracted through factor analysis. The accumulative contribution ratio is 76.92％. Factor 1 indicates the degree of obesity around the chest, factor 2 is the drooping degree of breast, factor 3 is the contours and prominence, factor 4 is the breast breadth and breadth of bust point, factors 5 is the volume of breast. The subject were classified into 3 cluster as their breast types through cluster analysis. Type 1 is the closest to the ideal breast shape and not too droopy. This group belonged to 75A. Type 2 has small breast and belonged to 70AA group. Type 3 is the obesest and has the biggest and droopy breast. This group belonged to 75B. The distribution of size of brassiere had 3 sections from 70 to 80 showing a rate of 81.94% and the sin of the cup had 4 sections from AAA cup to B cup showing a rate of 89.70％. The production ratio of each brassiere size, it was found that the brassiere size of highest production ratio was 75A(16.39％) in type 1,70AA(16.27%) in type 2, and 75B(13.72％) in type 3. This suggests that it is necessary to adjust for the production rate of brassieres.

The purpose of this study was to investigate the necessary functions and areas of improvement in bras worn by patients during the initial three-month recovery period after a breast augmentation procedure, and a functional bra that fits properly was designed. In order to analyze the necessary functions, a bra was designed after relevant discussions with medical staff and patients who underwent breast augmentation surgeries and considering the advice from bra designers and clothing and textile experts. This bra was designed to protect the surgical scars and minimize the compression by inserting a nonwoven fabric into the shoulder and front parts. In addition, it was designed in a way that could fit the individual breast volume by using a mesh material partially on the upper side of the molded cups. Underwires that could support the breasts were inserted, and a detachable wire was used to suit the patient's needs and the diagnosis by the medical staff. As the bra designed in this study received excellent scores during the evaluation by research subjects and experts, it can be used for designing the prototype of a functional bra.
