The purpose of this study is to classify breast types and to inquire about characteristics depending on breast types of women subjects in their twenties. We researched size items affecting breast volume and regression equations for the prediction of breast volume, and thereby, we will be able to provide some basic data, useful to the development of the brassiere depending on breast types. As a result of categorizing the types of three breast types, "type 1" was characterized by big and greatest protrusion of the breast with large breast volume and a large bust, while "type 2" was characterized by flat breasts with the least breast volume and least bust, and "type 3" was characterized by breast location apart from the center front line. Breast volume is significant in establishment of the brassiere cup depending on breast type. Five items such as, the circumference of the breast, the length of the upper breast, the depth of the breast point, the length of the shoulder point-breast point, and the length of the inferior breast were extracted through regression equations for breast volume.

To provide the basic data to manufacture superior brassiere, this study was analyzed the evaluation of wear sensation of brassiere and the satisfaction of breast type by breast circumference and volume of 182 twenties-aged women. The results were as follows: First, it was reliable to set up the cup size of brassiere by using the breast circumference. Hemispherical breast was the same as cone-shaped breast in breast classification by breast circumference and volume. Second, the breast sizes were able to classify into under 200cc, 200~300cc, 300~400cc, and over 400cc by volume, but measuring the volume was more difficult than measuring the breast circumference. Last, there were correlations between breast circumference and breast volume by breast type. And there were differences on improvement, brassiere size, and the satisfaction of breast type by breast circumference and volume. This results will give basic informations for brassiere design that reflects breast type according to breast circumference and volume for functional brassiere.

Volume-up pads are the most common and easiest way to make women with small breasts beautiful. In this study, to develop a volume-up brassiere pad with excellent wearing effects and appearance, 24 different types of volume-up pads commercially available in the online market were investigated and then 11 types were purchased. Among these eleven types, four pads (PAD1, PAD2, PAD3, PAD4) with distinct shapes and materials were selected through a pre-test. They were compared to the newly developed pad for research (PAD5). The results of the study follow. The results of evaluating appearance when wearing the developed pad (PAD5) were significantly higher than that of other pads, and the appearance evaluation score for the full-cup type pad was excellent. In the wearing satisfaction evaluation result, PAD5 showed generally excellent evaluation scores, and in the case of the touch, preference for the fabric material was higher than that of the silicon pad. In the evaluation of motion adaptability, the developed PAD5 showed generally excellent evaluation scores in all movements, indicating that the full-cup type pads had better motion adaptability than the partial-type pads.

본 논문에서는 유방 초음파 볼륨영상에서 진단하고자 하는 종양 영역을 율왜곡 기반(rate-distortion based) 시드영역 확장 법으로 분할하는 알고리듬을 제안한다. 제안된 분할법에서는 율은 윤곽의 거친 정도를 나타내고 왜곡은 영역의 동질성 정도를 나타내는데, 흉부 종양 볼륨으로부터 획득한 2차원 단면 영상에서 설정된 초기 시드영역에서 시작하여 이러한 율과 왜곡을 동시에 최소화하는 주위영역 중 하나씩 시드영역으로 병합한다. 이러한 병합은 시드영역의 윤곽 화소당 평균 율왜곡 비용이 최대가 될 때까지 반복적으로 수행한다. 이렇게 함으로써 최종 시드영역은 동질성이 잘 유지되고 부드러운 윤곽을 갖게 된다. 마지막으로 모든 단면 영상에 있는 최종 시드영역의 윤곽들을 이용하여 3차원 흉부 종양을 추출한다. 실험 결과, 제안한 방법이 초음파 데이터에 대하여 평균 에러율이 약 4% 미만으로 나타났다.

This paper analyzes desirable breast types using measurements from 31 selected female subjects based on the ratio of breast in works of art and to design a brassiere cup design according to the breast type of 182 female subjects in their 20s. The subjects selected for this paper are somewhat larger than a previous study on aesthetically perfect breasts of foreigners according to chest breadth, center neck point to breast point, breast circumference, and breast volume. However, the aesthetic breasts of foreigners are larger than the subjects selected for this study according to chest depth, under-bust circumference, and bust point to bust point. Comparing various breasts types and aesthetic breasts, padding is necessary to complement the form of flat breasts to increase the volume and diameter. Brassiere cups for cone-shaped breasts should be designed to increase breast volume through an increase in nipple height. Hemisphere breasts should be designed to increase the overall volume-leaving diameter. Protrusion breasts should enhance the functions of aggregating and supporting without any increase or decrease of the breast volume. Drooping breasts require the ability to support a large volume to stabilize the breast. Subjects were selected depending on the ratio of breast silhouette as works of art and who have large breasts in disproportional to a slender trunk. Three items, the circumferential length of breast, height of the nipple, and the depth of inner breast using the anthropomorphic measurements of 182 subjects were measured through regression equations for breast volume. Breast volume = -394.86 + 27.52 ${\times}$ (the circumferential length of breast) + 18.73 ${\times}$ (height of the nipple) + 12.85 ${\times}$ (the depth of inner breast). Regression equations to extract the aesthetic breast volume in measurements irrelevant to breasts using the anthropomorphic measurements of 31 subjects were as follows. Aesthetic breast volume = -611.30 + 17.67 ${\times}$ (bust circumference) -24.29 ${\times}$ (under-bust circumference) + 16.31 ${\times}$ (neck point to breast point to waistline) + 22.83 ${\times}$ (bust breadth) + 12.22 ${\times}$ (waist depth) -8.34 ${\times}$ (interscye- front). This prediction equation is useful to develop a breast type brassiere pattern, complement breast enhancement surgery, or minimize the effect a mastectomy.

This study provides basic data to develop a brassiere pattern that can cover the big breast of breast enlargement patients. In this study, we also showed areas of the brassiere cup pattern and the body surface of the breast on a breast enlargement patient. The results of the study are as follows. Correlation analysis was obtained between volume and body surface area and breast detail dimensions. After the correction process, we proposed a research bra pattern for breast augmentation patients. The cup-boundary in bra patterns of breast enlargement surgery patients is longer than the bra patterns of the general breast; therefore, the height of the inner and outer edges of the upper cups is higher. Also, it is necessary to set the new breast upper point when measuring the upper length in patients with breast augmentation surgery because the points of circumference of the breast are marked higher than chest circumference.

Big breasted women often experience dissatisfaction with ready-made brassieres, that do not account for individual breast types nor provide adequate cup sizes. This study was conducted to provide basic information on common breast shape and measurements of Korean big-breasted women, and to facilitate development of big-breasted women's bras with excellent fit and comfort. The study analyzed direct upper body measurements of 178 women in their 20's whith cup size C or bigger in the 5th, 6th and 7th Size Korea. In addition, 3D body scan data of women with bra size 75 and cup size C were re-collected and their breast types were examined. Average under-bust circumference of big-breasted women was 75 size in brassiere size. The average stature was 159.78 cm and the body weight was 60.33kg, indicating "overweight". Also, it was revealed that common breast types of big-breasted women, were hemispheric and cone types. The study can facilitate better understanding of breast shapes and sizes of standard big-breasted women, and will be useful as reference in selection of subjects in future studies.

Gaps between the upper edges of brassiere mold cups and the breasts are one of the most serious issues in realizing comfort wearing of commercial brassieres for small-breasted women. The surplus ease amounts causing the fit problem were measured from 3D wearing images of the small-breasted women's brassieres. The effect after the removing the surplus ease amounts from the upper edge of mold cup was approved by subjective wearing evaluation. Since the volume distribution of mold cup can also affect the wearing sensation of brassiere, the subjective wearing sensation was compared for two brassieres of different volume distributions, V_L, of which volume was concentrated at the lower cup, and V_C, which has the thickest part at the nipple. As the results, the suitable sensation for cup volume and the natural wearing silhouette could be accomplished by removing the surplus ease amounts from the upper edge of mold cup to reduce the gaps between brassieres and the breasts, which could be accomplished through an approach reducing the volume near the upper edge of mold brassiere cup and making the volume concentrated at the lower cup. These works provide a useful information on the design of the brassiere mold cups for small-breasted women. Moreover, modeling methods of 3D scan data and 3D printing technique for making more accurate mold cases used in this research can be helpful to develop and evaluate clothing products in future.
