The purpose of this study is to improve the fitness of clothes by producing patterns considering body proportions at a time of producing clothes for export through extracting factors comprising body types and conducting comparative analysis of proportions by body part using body indexes of Korean women in their 20s living in both Korea and foreign countries. The study results are as follows. Factor analysis by group was conducted for body indexes in order to examine body types of Koreans living overseas. As a results, six factors were extracted from all of three groups; Joseonjok(Koreans living in China), Goryeoin(Koreans living in Russia) and Korean residents in Japan, and their explanatory powers were 60.42%, 63.62%, 63.15%, respectively. Obesity factor was extracted as the 1st factor, and the groups showed differences in other factors. As a result of proportion comparison using body indexes of Koreans living in foreign countries and Korea, it was found that, in height item, when regarding the height as 100, the length of the lower part of the body was long in the order of Goryeoin. Joseonjok, Koreans living in Korea and Korean residents in Japan. Also in width item, when regarding the waist as a standard, it was observed that Joseonjok people have the shoulders, the breasts and the hips that look relatively wider comparing with the width of the waists because they have very narrow waists and the width between shoulder length is big. In addition, the study examined proportions of the breast thickness/the breast width, the waist thickness/the waist width, the hip thickness/the hip width to height. From the analysis, it was found that breasts of Koreans living in Korea are flattest while their waists are slender, and Goryeoin and Joseonjok have round body shapes from the waist to the breast.

The study was aimed to develop a torso-type dress form representing body features of the female fashion models in Korea. To fulfill this purpose, 5 female fashion models aged between 20 and 26 having the average body measurements of professional fashion models in Korea were selected and their 3-D whole body scanned data were analysed. The 3-D whole body scanning method enabled to generate a virtual female fashion model within the CAD system by measuring the subjects' body shapes and sizes. In addition, the virtual model's body data led the development of a standard female fashion model dress form for the efficient fashion show preparation. In order to manufacture the real dress form for female fashion models, 3-D printing technology was adopted. The consequent results are as follows: (1) the body measurements (unit: cm) of the developed dress form were: biacromion length, 36.0, bust point to bust point, 16.6, front/back interscye lengths, 32.0/33.0, neck point to breast point, 26.0, neck point to breast point to waist line, 41.5, waist front/back lengths, 34.5/38.5, waist to hip length, 24.0, bust circumference, 85.0, underbust circumference, 75.0, waist circumference, 65.0, hip circumference, 92.0. (2) the body measurements differences between the developed and existing dress forms were highlighted with the body measurements of neck point to breast point and waist to hip length. (3) the body shape features of the developed dress form showed that bust, shoulder blade, shoulder slope, abdomen and back waist line to hip line parts were more realistically manufactured.

The early detection of brest cancer is clearly a key ingredient for any strategy designed to reduce breast cancer mortality. Microcalcification(MCC) is one of the primary signatures to discriminate between normal and cancerous tissue. The detection and locating procedures can be automated by digital image processing, however, MCCs have various sizes, shapes, and intensity levels in film images, so it is difficult to find accurate locations and sizes. Firstly, we made quantitative analysis for many characteristic features of mammograms that can be used to segment MCCs from normal tissues. Secondly, we developed algorithms proper to segmentation like pattern matching. The performance was evaluated with TP and FP rates.

목적: 유방암 환자에서 부분적 유방절제술 후 내유림프절(internal mammary lymph node: IMN)을 포함하여 방사선 치료하기 위한 최적의 치료 방법을 찾고자 하였다. 대상 및 방법: 초기 유방암으로 부분적 유방절제수술을 받고 방사선치료를 받은 10명의 환자들의 CT simulation 데이터를 얻어서 각 환자들에서 4가지 치료방법을 계획하고 평가하였다. 5명은 오른쪽 유방을, 나머지 5명은 왼쪽 유방을 치료 받았다. 각 환자에서 유방, 쇄골 상부 림프절(supraclavicular lymph node: SCL), IMN (위쪽 3개의 늑골 사이에 있는 림프절만 포함)을 조사하는 치료계획을 하였다. IMN을 조사하는 방법으로 4가지 방식, 즉 표준적인 접선방향 치료(Standard Tangential Field: STF), 확장접선치료 방법(Wide Tangential Field, WTF), 부분 확장접선치료 방법(Partially Wide Tangential Field: PWT), 광자와 전자를 혼합한 방법(Photon-Electron Mixed 5 Field: PEM)을 사용하였다. SCL field는 3 cm에, 유방조직은 중심점에 50.4 Gy를 28회에 나누어 치료하도록 처방하였다. 결과: 각각의 치료 기법은 환자마다 차이는 있었으나 뚜렷한 특징을 보였다. 유방조직의 선량은 각 치료 기법마다 큰 차이가 없었다. IMN는 치료 기법마다 차이가 있으나 STF를 제외한 세 가지 방법은 대체로 IMN을 잘 감싸고 있었다. 왼쪽 유방을 치료하는 경우 심장이 받는 선량은 고선량 영역에서는 WTF, PWT, PEM, STF의 순으로 많은 체적에 선량을 받았으며 낮은 선량 영역에서는 PEM, WTF, PWT, STF의 순이었다. 동측 폐의 선량 역시 마찬가지의 순서를 보였다. Lyman-Kutcher-Burman model에 의한 방사선 폐렴에 대한 NTCP는 개인별 편차가 컸다. 대체로 STF가 가장 작고 PWT가 다음이었으나 PEM와 WTF의 경우는 환자마다 큰 차이를 보였다. 결론: 환자들의 다양한 체형에도 불구하고 IMN를 포함하여 치료하는 경우 PWT가 폐와 심장의 조사선량을 줄이고 IMN에 표적선량을 전달하는데 적합한 것으로 생각된다.

Background Various shapes and designs of the gluteal artery perforator flap have been used for treating sacral pressure sores and reconstructing breasts. To establish the ideal fasciocutaneous flap design for use in the gluteal area, the soft tissue thickness distribution was measured. Methods Twenty-one buttocks of adult Korean cadavers were analyzed through rectangular subfascial dissection. Each buttock was divided horizontally into 10 sections and vertically into 10 sections, and then, the thickness at the corners of the sections was measured. For the sake of comparison and statistical verification with living bodies, computed tomography (CT) images of 120 buttocks of patients were randomly selected. Five horizontal sections and 4 vertical sections were made, and the thickness at each corner was recorded. Results According to the dissection and the CT images, the area with the thinnest soft tissues in the buttock was around the posterior superior iliac spine, close to the sacral area. The thickest area was the superolateral area of the buttock, which was 3.24 times and 2.15 times thicker than the thinnest area in the studies on cadaver anatomy and the CT images, respectively. Conclusions The thickness of the soft tissues in the buttocks differed by area. The superolateral area had the thickest soft tissues, and the superomedial area had the thinnest. This study includes information on the distribution of the thickness of the gluteal soft tissues of Koreans. The outcome of this study may contribute to the design of effective local flaps for pressure sore reconstruction and free flaps for breast reconstruction.

Gold nanoparticles (AuNP) and their conjugates have been gaining a great deal of recognition in the medical field. Meanwhile, extended-spectrum ${\beta}$-lactamases (ESBL)-producing bacteria are also demonstrating a challenging problem for health care. The aim of this study was the biosynthesis of AuNP using Rosa damascenes petal extract and conjugation of ceftriaxone antibiotic (Cef-AuNP) in inhibiting ESBL-producing bacteria and study of in vitro anticancer activity. Characterization of the synthesized AuNP and Cef-AuNP was studied. ESBL-producing strains, Acinetobacter baumannii ACI1 and Pseudomonas aeruginosa PSE4 were used for testing the efficacy of Cef-AuNP. The cells of MCF-7 breast cancer were treated with previous AuNP and Cef-AuNP at different time intervals. Cytotoxicity effects of apoptosis and its molecular mechanism were evaluated. Ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy established the formation of AuNP and Cef-AuNP. Transmission electron microscope demonstrated that the formed nanoparticles were of different shapes with sizes of 15~35 nm and conjugation was established by a slight increase in size. Minimum inhibitory concentration (MIC) values of Cef-AuNP against tested strains were obtained as 3.6 and $4{\mu}g/ml$, respectively. Cef-AuNP demonstrated a decrease in the MIC of ceftriaxone down to more than 27 folds on the studied strains. The biosynthesized AuNP displayed apoptotic and time-dependent cytotoxic effects in the cells of MCF-7 at a concentration of $0.1{\mu}g/ml$ medium. The Cef-AuNP have low significant effects on MCF-7 cells. These results enhance the conjugating utility in old unresponsive ceftriaxone with AuNP to restore its efficiency against otherwise resistant bacterial pathogens. Additionally, AuNP may be used as an alternative chemotherapeutic treatment of MCF-7 cancer cells.

The aim of this study was to analyze the features of bodice patterns modeled using a dress form that represents Korean female fashion models' body features. A controlled experiment was carried out using an existing dress form that has been frequently used in South Korea. The purpose of the study was to suggest notable findings derived from understanding the development of bodice patterns for Korean female fashion models. The comparison of features of bodice patterns from the developed and existing dress forms was carried out with consideration of the upper body features of the developed dress form, such as body angles and body cross-sectional shapes. The following results were derived from the investigations. (1) The angles of the upper and lower breast cups of the developed dress form differed to those of the existing dress form, showing a 5.0cm smaller front shoulder dart and a 3.5 larger ㎝ ㎝ front waist dart within the bodice patterns. (2) The body angle features of the developed dress form included a straighter neck and shoulder blade and more concave center back than the existing dress form, with a 2.0 reduced back neck height and a 4.8 larger back waist dart for ㎝ ㎝ the bodice back panel. The more realistic body angles of the developed dress form anticipate the improvement of garment pattern-making. (3) The altered shoulder angles resulted in an increased size of the back shoulder dart and a decreased size of the front shoulder height within the bodice patterns. (4) The increased rate of curvature of cross-sectional shapes on the bust and waist circumferences of the developed dress form resulted in an increase in the sizes of the front and back waist darts.

Pearl gowns(Jeanju-eui)' of Princess Jekukdaejang which were imported from Yuan to Goryeo in 13'th century, but correct shape and detail were unkown. Princess Jekukdaejang was a queen of Goryeo and a daughter of Kublai Khan of early Yuan period, and pearls were the most precious jewel in Mongolia of medieval time. It is possible that the shapes of Jeanju-eui were nomadic mogolian women's costume or very new style yet in early Yuan just like sleeveless long vest. In the period of Yuan, pearls were beaded on the stiff thin fabric for summer or ornaments of ladies. Big pearls were made use of point spot of pattern or line of pattern, and small pearls were usually used to fill up devided parts or to bind outline. The shapes of deducted pearl gown are five kinds of women's deel and four kinds of long vest, and deducted parts for pearl decoration are golden band from shoulder to wrist and on the knees of gown, cloud shape collar, patches on the breast and on the back, slant collar, and patterns of fabric. Red color(the favorite color of Yuan ladies), artifical pearls, ramie, and golden brocade with the gloss of satin are selected as stuffs for sample of pearl gown, but 'reproducting old fabrics' was the most important problem in making correct pearl gowns. Suggested is a cooperation with fabric makers to develop alternate fabircs with patterns just like Yuan's.
