For the establishment of ready made Hanbok for the people in their 20's this study aims to develope Bagi-chogori pattern that revives the esthetic quality of the traditional Hanbok as well as comfortably fit the body. Direct method was used in Measuring the 33 parts of men which was selected as items needed for the analysis of the body and the development of patterns. In accordance with the body measurement and the analysis of the result the bust girth and height which has interrelation was chosen as the standard size for the development of pattern. Men's Baji-chogori(Korean traditional Jacket and Pants) which doesn't request fitness for instance we drew out a cross table by giving 5cm intervals each for breast waist hip girth and height. Size system of Baji-chogori was 4 steps. 1st was bust 95cm height 165cm 2nd was bust girth 95cm height 170cm 3rd was bust girth 100cm height 175cm and the 4th was bust girth 105cm height 180cm. In the case of Men the grouping of bodies was attempted by concentrating on the difference of the drop amount(Bust girth to hip girth), However 90% of men in their 20's showed a silhouette of an inverted triangle. Therefore attempt for an additional grouping wasn's Only calculation concerning the ease amount of items such as bust which and length was considered to enhance the silhouette of Hanbok when worn. Men's body for instance have a tendency to change to a rectangular shape as they get older. specially the abdominal girth trend to increase greatly. So study and development of pattern should be made for all age groups.

Purpose: Good color match holds a key position in facial reconstruction for good aesthetic result. To correct the wide facial soft tissue defect were usually used the tissue expanded cheek flap, deltopectoral flap or radial forearm free flap. This study is aimed to analyse the color difference after flap surgery by using chromameter. Method: From August 1995 to December 2006, 30 patients underwent flap operations were chosen randomly and evaluated color differences between flap site and adjacent skin. Reconstructive procedures included tissue expanded cheek flap(n = 10), deltopectoral flap(n = 10), and radial forearm free flap(n = 10). The measured sites were flap center within a radius of 1 ㎝ and four points of adjacent skin along the flap margin. The color was quantified in a three dimensional coordinate system $L^*$ (brightness), $a^*$ (redness), $b^*$ (yellowness). Results: There was no significant color difference between the pedicled flaps(tissue expanded cheek flap and deltopectoral flap) and adjacent skin area. On the other hand, color values of the radial forearm free flap were statistically different from those of adjacent skin area. Total color difference(${\Delta}E$) of tissue expanded cheek flap and deltopectoral flap were $7.45{\pm}5.78$ versus $9.41{\pm}7.09$, and that of radial forearm free flap was $11.74{\pm}3.85$. They suggest that pedicled flaps have a potential of better color match than radial forearm free flap. Conclusion: Thus, better esthetic result and satisfaction is more likely to be expected in pedicled flaps as long as it could be applied comparing radial forearm free flap.

The lower extremity injuries are extremely increasing with the development of industrial & transportational technology. For the lower extremity injuries that result from high-energy forces, particularly those in which soft tissue and large segments of bone have been destroyed and there is some degree of vascular compromise, the problems in reconstruction are major and more complex. In such cases local muscle coverage is probably unsuccessful, because adjacent muscles are destroyed much more than one can initially expect. Reconstruction of the lower extremity has been planned by dividing the lower leg into three parts traditionally The flaps available in each of the three parts are gastrocnemius flap for proximal one third, soleus flap for middle one third and free flap transfer for lower one third. Microvascular surgery can provide the necessary soft tissue coverage from the remote donnor area by free flap transfer into the defect. Correct selection of the appropriate recipient vessels is difficult and remains the most important factor in successful free flap transfer. Vascular anastomosis to recipient vessels distal to the zone of injury has been advocated and retrograde flow flaps are well established in island flaps. Retrograde flow anastomosis could not interrupt the major blood vessels which were essential for survival of the distal limb, the compromise of fracture or wound healing might be prevented. During 5 years, from March 1993 to Feb. 1998, we have done 68 free flap transfers in 61 patients to reconstruct the lower extremity. From analysis of the cases, we concluded that for the reconstruction of the lower extremity, free flap transfer yields a more esthetic and functional results.

PURPOSE. We aimed to identify a more esthetic width-to-length ratio by analyzing maxillary central incisor of Korean adult population. Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. MATERIALS AND METHODS. A total of 40 men and 40 women were included in this study. The NON-MEDIA group included 40 non-celebrities, who were healthy and 25 to 39 years old, with normal dentofacial appearance. The MEDIA group consisted of 40 celebrities selected only on the basis of their soft-tissue facial appearance. The facial photographs of 40 celebrities were collected from the Internet websites. The width and length of the maxillary central incisor were measured using Adobe $Photoshop^{(R)}$ 7.0, a software for analysis, measurement and edition of photographs. Data were analyzed statistically using the Independent t-test at 5% statistical significance level. RESULTS. The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88. The difference between the two groups was statistically significant. No significant gender differences were found in the width-to-length ratio in MEDIA group. In NON-MEDIA group, however, there were significant differences between female and male. CONCLUSION. After analyzing maxillary anterior teeth of Korean adults, our results were in accordance with the general Western standards of esthetics. A dentist restoring the natural look and beauty of teeth will have to consider those standards.

This study aims to integrate sports uniform design into fashion as an effective communication means by analyzing the uniforms of women's pro basketball and volleyball teams in the country. As part of the research method, a literature review was conducted on the domestic pro sports background and women's basketball and volleyball uniforms. For empirical research, an analysis was performed of the uniforms of 12 teams in total: six women's pro basketball teams and six women's pro volleyball teams in the 2013~2014 league. The following results were obtained. First, in terms of formativeness, sleeveless shirts and shorts are basic in both basketball and volleyball. However, there are remarkable differences between the two. Shirts in volleyball are tighter, with the body figure visible, and shorts are shorter in length than those in basketball. Most basketball uniforms have a V-neckline and are collarless, while volleyball uniforms have a standup collar in all teams. Second, both basketball and volleyball apply the representative color of the sponsoring company and the team's typical color, but common colors, such as blue, navy, and white, are used in many teams, which fails to represent a uniquely differentiated image. Third, the logo or symbol of a sponsor is excessively applied to both basketball and volleyball uniforms. This downgrades the uniform's own esthetic features. Fourth, a fashionable uniform design, that reflects the bodily characteristics of women and the characteristics of the sports game would be a beneficial communication tool for all the tiers to become involved in participation and entertainment.
