It is essential to apply compression bands or pressure garments that can stabilize the breast implants and breast shape as well as help shape the breast to the desired shape immediately after breast augmentation surgery. It is necessary to study the compression garment which is able to properly cover a deformed breast due to the operation and shape it as a beautiful breast. The subjects of the study were 6 women who experienced breast augmentation surgery with an under bust size of 70 or 75, cup size of C cup with a hemispherical and conical shape. We analyzed the dissatisfaction and satisfaction factors through the evaluation of the 4 types of commercial compression garments and developed the new functional post-operative bra which can be worn immediately after the operation according to the breast characteristics of breast augmentation patients. We have developed new bra patterns; a front opening type garment with wings and a band type garment both sides that allow the band to be pressed from the front center. The comparative wearing evaluation indicated that the superiority of the new compression garments also provided a higher the satisfaction of the newly developed bra (front adjustable style) than a commercial band.

Due to recent changes in increased life expectancy, economic power and social development, the new senior generation (focusing on people in their fifties) represents a new market power with strong competitiveness. The new senior generation is the generation after the baby boomers, with characteristics that include a high-level of education, increased income, a high-level of consumption, increased assets, self-fulfillment desires and individuality. Demands in the senior fashion industry are expected to gradually increase and the underwear industry that targets the new senior generation is expected to grow rapidly. These demands will require product development for the new senior generation based on emotional and socio-cultural characteristics. The current new senior underwear market is under the process of R&D with a focus on body shape changes; however, there are limited studies on emotional and socio-cultural approaches. This study formulates a basic design plan for different age groups based on an analysis of the situation of bra wear (current inconveniences, demand and needs) by women in their fifties and over. Subsequently, a functional active bra top that considers activity and comfort was proposed for women in their fifties, an all-in-one foundation bra top that shapes the body was proposed for women in their sixties, and comfort bra tops that are comfortable and easy to put on and take off were proposed for women in their seventies and over.

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.

This thesis intends to suggest a new wedding dress pattern through researches on history and changes of wedding dress, researches on silhouette and details and analyses of existing basic patterns. In this study, to develop torso patterns of top dresses selected as preferred designs through literature reviews and company surveys, dress form sizes suitable for standard sizes were selected and study basic patterns were made using draping techniques. The study finds characteristics of body type dimension that is changed when wearing brassiere (hereinafter, 'bra') for wedding dress through customer surveys for development of basic patterns of wedding dress. That is, wearing wedding bra was used for the purpose of increasing the bust size and we will evaluate later whether this increase helps completeness of aesthetic impression through wearing evaluation. As the result, it was found out that top torso pattern wearing wedding bra made wearers feel more comfortable and in the aspect of aesthetic impression, it provided impacts on women's beautiful silhouettes. The effects of whether a bra is used or not on changes in patterns were reviewed through the degree of polymerization of finished patterns. When a bra for dresses was worn, the waist front length increased by1.7cm, the bust circumference increased by 2.1cm, and the amount of dart increased by 1.5cm in the patterns. A new torso pattern for top dresses, which will solve problems evaluated in each of the above from the aspect of composition of pattern by a method through analysis of existing basic patterns and multi-dimensional cut patterns wearing wedding bra, will be suggested.

This research sought to analyze the characteristics of breast movement at the treadmill activity levels. It also examined the effect of wearing a sports bra in reducing breast displacement. The subjects for the data collection were females in their 20s (n=2) with C-cup size breast. The experimental conditions were three different moving speeds (4 km/h, jogging: 7 km/h, and sprinting: 10 km/h) and two types of sports bras. Three dimensional breast displacement was measured. The displacement of the right nipple point was measured with a 3D motion analyzer. The results show that the breasts were greatly displaced from the walking speed (4 km/h) when subjects did not wear any bra. Whereas their breast displacement distance decreased remarkably when they wore sports bras. The nipple point moved 42~44 mm in the vertical direction at walking speed with naked condition. But it was reduced by 80% after wearing sports bras. When subjects running (7 km/h, 10 km/h) without any bra, the nipple point moved 122~141 mm. However it was reduced by 60~70% when they wore sports bras. The apartment time (time delay) between at the highest point of the upper body and the nipple was 0.25 seconds at the running speeds (7 km/h, 10 km/h) without wearing any bra. After wearing sports bras, the time delay was cut to 0.06~0.12 seconds. These results implies that without wearing any bra the skin surrounding the breasts might be seriously pulled at running activity. The functional sports bra suppress breast movement. It might prevent the sagging of breasts by preventing the damage of the Cooper's ligaments.

In the agricultural industries, LEDs are used as supplementary, as well as main lighting sources in closed cultivation systems. In cultivation using artificial light sources, various light qualities have been tried to supplement fluorescent lamps to promote plant growth and metabolism. Microarray analysis of Brassica rapa seedlings under blue and fluorescent mixed with blue light conditions identified changes in three genes of the glucosinolate pathway. This attracted attention as functional materials highly expressed 3.6-4.6 fold under latter condition. We selected four more genes of the glucosinolate pathway from the Brassica database and tested their expression changes under fluorescent light mixed with red, green, and blue, respectively. Some genes increased expression under red and blue mixed conditions. The Bra026058, Bra015379, and Bra021429; the orthologous genes of CYP79F1, ST5a, and FMOGS-OX1 in Arabidopsis, are highly expressed in Brassica rapa under fluorescent mixed with blue light conditions. Further, Bra029355, Bra034180, Bra024634, and Bra022448; the orthologous genes of MAM1, AOP3, UGT74B1, and BCAT4 in Arabidopsis, are highly expressed in Brassica rapa under fluorescent mixed with red light conditions. The various light conditions had unique effects on the varieties of Brassica, resulting in differences in glucosinolate synthesis. However, in some varieties, glucosinolate synthesis increased under mixed blue light conditions. These results will help to construct artificial light facilities, which increase functional crops production.

The purpose of this study was to investigate the effects that breathing, thoracic and abdominal, had on the smoothness while performing ballet pour de bra. Five skilled ballet dancers(age: $24{\pm}1$, height: $163.4{\pm}2.88$, weight: $44.4{\pm}1.34$) with experience of over 10 years participated in this study. Each participant performed the ballet movement three times with abdominal respiration and with thoracic respiration. The kinematic data was recorded at 60 Hz with three digital cameras (Sony VX-2100). The pour de bra movement consists of two phases, up and down. The up phase is defined as the movement from the en bas through the en avant to the en haut. The down phase is defined as the movement from the en haut through the $\grave{a}$ la seconde to the en bas. During these two phases the Jerk Cost (JC) factor was calculated for the shoulder, elbow and wrist to quantify the smoothness. The group who performed the movement while abdominal respiration had a lower JC factor and so it was concluded that while abdominal respiration the smoothness of the movement was increased as opposed to the thoracic respiration.

The bra is one of the most essential pieces of women's underwear which gives support for the breasts and holds them in position to make better outer appearance of upper body. Despite being worn by most women of all ages, brassiere manufacturers often use brassiere sizes and shapes that are close to the body measurements of women in their 20s, which raises questions whether the bras are suitable for older women's physique. Also, many lingerie markets tend to center on designs and tastes of younger women, leaving those of older women are largely ignored in the manufacturing process despite the fact that their purchasing power and market shares are expected to grow in conjunction with the aging of the global population. Against this backdrop, this study attempts to provide information about bra preferences and breast perceptions of the middle-aged and older US women over the age of 40 years to help manufacturers better understand the bra purchasing priorities and bra elements of older women and prompt them to design bras with a high level of fit and comfort that are appreciated by the population groups as a means to ultimately acquire competitive edge in the fast growing aging market. An email survey and interviews were conducted with 301 US women who live in New York City. The findings of this study suggest that there are internal and external factors such as changes in body and breast shapes with age influence the level of fitness and effectiveness of bra components, and thus the responses to the questions on bra preferences and breast perceptions varied between the researched age groups.

We analyzed QTLs for alkali-related digestion by using 120 population crossed Cheongcheong and Nagdong derived from anther culture (CNDH). The DNA markers located in the QTLs gene were selected and applied to existing cultivars. As a result of the investigation of the alkali decay degree, brown rice of Cheongcheong and Nagdong was 1.9 and 1.6, respectively, and the CNDH was $3.79{\pm}2.01$, and the distribution of variance was distributed to 7.0-1.0. The milled rice of Cheongcheong and Nagdong was 5.6 and 4.1, respectively. The mean of the CNDH was $4.86{\pm}1.55$, and the distribution of variance was distributed to 7.0-2.0. Variation distribution curves showed continuous variation that was close to non-normal distribution. In the QTLs analysis, qBRA2, qBRA6, and qBRA11 were mapped in 1-2 replications of brown rice. QHRA2-1, qHRA2-2, qHRA2-3, qHRA3, and qHRA8 were mapped in the first replication. QHRA2-1, qHRA2-2, qHRA2-3 and qHRA3 were mapped in the second replicates. And mapped to qHRA5 in 4 replicates. These were found on chromosome 2, 3, 6, 8 and 11, respectively. The phenotypic variations of qBRA2, qBRA6, and qBRA11 on the chromosomes of brown and milled rice were 1-9%. The polymorphism was analyzed for 12 types of the japonica type and six types of the indica type, based on the nine markers found in the QTLs analysis of alkali digestion. Chromosome 11, RM27258, was selected to determine the segregation ratio, which shows the difference in size by the band pattern. The results of this study will be used as basic data for the development of high-quality rice cultivars.
