Many women feel pain in their breasts while running due to an excessively large degree of breast movement. Therefore, most sports bras pursue a reduction in breast movement. The purpose of this study is to investigate the breast movement reduction effect of a selection of sports bra designs according to the intensity of the sport and the breast size of the wearer. The study measured differences in the vertical movement of the nipple with 4 types of sports bras and 3 exercise speeds(4km/h, 7km/h, and 10km/h). Subjects included women in their 20s with bra sizes of either B cup(n=3) or C cup(n=3). The results of the study are as follows. Breast movement differed according to running speed and breast size; breast movement significantly increased starting with jogging speed(7km/h), and the C-cup group had a larger degree of vertical movement than the B-cup group. A superior effect on breast movement during jogging(7km/h) and sprinting(10km/h) was observed differently by bra cup sizes. To C-cup group, encapsulation-style sports bra, which provides horizontal support across the upper breast and padding inside the shoulder strap and bra cup to ease impact was most effective and next effective style was the compression-style bra with a princess line to cover the breasts solidly. Most style sports bra were effective in the B-cup group. Besides aforementioned encapsulation-style sports bra, the compression-style bra with a band, which presses the breasts against the chest wall, reduced breast movement effectively.

The purpose of this study was to compare fitting of the upper garment by brassiere cup size and types of bodice block. This study conducted a 3D virtual garment system by applying three types of bodice block (I, II, III) and experimental pattern of the bodice block to 3D avatars of four individuals with the following measurements: under bust circumference of 73.5 cm and bust circumferences of 83.5 cm, 86.0 cm, 88.5 cm, and 91.0cm. The results of the study were as follows. First, for 83.5 cm bust circumference (A Cup), appearance of the three types of bodice block (I, II, III) was appropriate. However, as bust circumference increased in size, shape became inappropriate. The depth and width of the armhole, within 15 cm and 11 cm, respectively, were found to be appropriate. In case of 91.0 cm bust circumference (D Cup), all three bodices (I, II, III) were inappropriate. Second, the results of the draft of the experimental patterns of the bodice block of bust circumference measuring 83.5 cm, 86.0 cm, 88.5 cm, and 91.0 cm in the 3D avatars of the four individuals revealed similarities in the frontal view of the silhouette in the four avatars; in the case of the lateral view of the silhouette, lateral width grew wider as bust circumference of the silhouette became larger, but the shape of armhole showed no changes. The depth of the armhole showed little changes from 15.1 cm to 15.22 cm, and the height of sleeve (armscye depth 13.6 cm within +2 cm) remained similar. The difference in width of the armhole from 11.26 cm to 11.37 cm was rather small. The width of the upper sleeve (8.97 cm) seemed to be appropriate as it remained within the 2-3 cm boundary.

This study was conducted comparative analysis of juvenile brassiere and adult brassiere to identify the problems of brassieres on the market. The raw data for this study was processed by SPSS 10.1 version(statistical software) and the results of this study can be summarized as follows. 1) The result of comparative analysis of juvenile brassiere and adult brassiere pattern is that each pattern showed no difference. 2) The results of the comparative analysis of juvenile and adult brassiere pattern in wing's length and angle is that even though there are some difference between juvenile and adult in side line inclination of brassiere. there is no setting difference but size of that brassiere. 3) The result of a comparative analysis pattern and cup size measurement of juvenile brassiere and adult brassiere is that even though the adult cup girth and angle is bigger than the juvenile because adults have more protrusive and bigger volume and well developed breast, some case rather the adult's cup angle is smaller than the juvenile as brand. And as we grow up to be a woman, difference of lower breast girth and breast girth are become big while difference of upper breast girth and breast girth are become small for that reason upper cup must be lower and lower cup must be higher but there is almost no difference between adult and juvenile. 4) The result of a comparative analysis of juvenile brassiere and adult brassiere bust point of the pattern is that adult brassiere's distance between bust points 6.12cm, and juvenile's 5.6cm, there are only 0.52cm difference between two products and just 0.4cm, size grading. These results are explained that even though when grow up to be a woman the distance between two bust points become to be long and breast toward out side but brassiere size don't vary with body characteristic.

The flash point, explosion limits, autoignition temperature(AIT) are important combustible properties which need special concern in the chemical safety process that handle hazardous substances. For the evaluation of the flammable properties of n-butylacetate, this study was investigated the explosion limits of n-butylacetate in the reference data. The flash points, fire points and AIT by the ignition delay time of n-butylacetate were experimented. The lower flash points of n-butylacetate by using the Setaflash and Pensky-Martens closed-cup testers were $24^{\circ}C$ and $26^{\circ}C$, respectively. The flash points of n-butylacetate using the Tag and Cleveland open cup testers are measured $31^{\circ}C$ and $40^{\circ}C$, respectively. And the fire points of n-butylacetate by the Tag and Cleveland open cup testers were measured $32^{\circ}C$ and $41^{\circ}C$. The AIT of n-butylacetate measured by the ASTM 659E tester was measured as $411^{\circ}C$. The lower explosion limit of lower flash point $24^{\circ}C$, which was measured by the Setaflash tester, was calculated to be 1.40 vol%. Also, the upper explosion limit of upper flash point $67^{\circ}C$ the Setaflash tester was calculated to be 12.5 vol%.

The purpose of this study was to analyze the breast growth variation trends and characteristics of Korean adolescent girls based on 3D body measurements. Subjects were 174 girls aged between 13 and 18. 3D body scanning data were collected and the data were measured by Geomagic Design X program. The total of 18 anthropometric measurements and 4 index items were analyzed. The main results of this study are as follows: 1) Overall, the breast growth of adolescent girls got out of children's body shapes at the age of 14 and the adult's body shapes appeared remarkably at the age of 18. Before the age of 15, the adolescent girls' breast enlarged. 2) The surface lengths of upper body, which means the breast volume, showed significant growth above B cup groups rather than under A cup groups. The demand of B cup size (32.2%) was higher than A cup size (25.9%). And 35.6% of subjects' brassiere band size was 70. 3) The thorax grew evenly in the circumference, depth and breadth. The thoracic development related to the breast volume as well as the whole upper body's development. These results reveal that it is necessary to develop adolescent girls' brassiere reflecting on adolescent girls' breast growth variation trends and characteristics by age, breast size and thoracic development.

The study provides baseline data on developing ready-to-wear clothes for adult females in their twenties who have finished shaping their bodies and have realized an ideal shape. We analyzed the data from females aged from 20 to 29 in "The $5^{th}$ Size Korea Survey" and "The $6^{th}$ Size Korea Survey", and sorted body shapes into several types according to drop values before analyzing and comparing the characteristics among groups. We also referred to the change by year in the size of upper inner wear. To classify body shapes, three drop values were assigned for bust girth - waist girth, hip girth - waist girth, hip girth - bust girth; through cluster analysis all data were classified into three body types. Type 1 is more like normal body shapes with small drop values at the bust girth - waist girth and well-build lower body. Type 2 is X-shaped body shaped like a fiddle with big drop values at all parts. Type 3 is Y-shaped body with a big drop value at the bust girth - waist girth and well-build upper body. Type 2, X-shaped body, has the majority of distribution in every year, which proved to be the most idealistic body shape. There was a change in the brassiere cup size. Korean ladies in their twenties have larger breasts. The body shapes of Korean females in their twenties are increasingly like those of westerners. Bust girth is a very critical element to set measurements and design patterns for upper wear; consequently, a change in the size of breasts should be considered.

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.
