In cold winter season, the apparatuses of heating and heater which warm up the interior of a room are necessary element and the used amount of these apparatuses from the year 2000 has been increased abruptly. But, the fire accident and the danger of fire are also increased. Therefore, 3D modelling is done by referring three kinds of the electric heaters as the heaters of ceramic, carbon and near infrared ray sold in the city for the design of more safe heating apparatuses in this study. The thermal analyses with these models are carried out and the durabilities due to the thermal deformation and stress are studied. By the background of the study results derived in this study ultimately, the durabilities of electric heater models due to each shape can be anticipated and contributed to the development of new heating apparatus with more safe resistance to fire. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

In this study, CFRP and metal or nonmetal were bonded with adhesive and the fracture study on this material was carried out. CFRP at the upper side of specimen and metal or nonmetal were assigned at the lower side of specimen by using DCB specimen as the analysis condition. And it was desribed that the structural adhesive were bonded between both upper and lower sides. As this analysis result, the least equivalent stress was shown at the specimen bonded with aluminium. The maximum shear stress was shown to become lowest at the de-bonded CFRP specimen when titanium was used. In conclusion, it was shown that the deformation of specimen became lowest when titanium was used. On the basis of this study result, the esthetic sense can be shown as the fracture data of bonded interface using adhesive are grafted onto the real life.

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.

Excessive teeth abrasion causes pathologic changes of oral environment and masticatory system due to decrease in occlusal vertical dimension. When establishing new occlusal plane and recovering vertical dimension, accurate diagnosis and analysis are essential. In this case, after appropriate centric relation in elevated vertical dimension was taken using Gothic arch tracer, full mouth rehabilitation was performed. A 70-year-old male patient had the chief complaint that he could not eat due to teeth wear. He showed generalized teeth wear and decreased vertical dimension. Elevation of vertical dimension was planned by model analysis. According to increased vertical dimension, centric relation was recorded using Gothic arch tracer and temporary prostheses were applied. Appropriate occlusion was established by temporary prostheses for 4 months. Final prostheses were fabricated using vertical dimension adapted by temporary prostheses. Through this procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.

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.

In this paper, the fracture behaviour at CFRP laminated structure due to the vertical falling impact of the fight drone frame composed of CFRP was investigated through the analytical study. As CFRP consists of fiber differently from the existing plastic material, the fracture behaviour becoms complex. So, the preceding study is important through the analytical study before this experiment. By comparing with the existing study model at the same condition as the result of this study, the applied stress value is shown to decrease greatly at the analysis model with the center notch hole of the laminated CFRP drone frame. On the basis of this study result, the esthetic sense can be shown as the foundation data about the notch hole of drone frame are grafted onto the convergence technique.

Secondary deformities of the lip and nose in individuals with repaired unilateral and bilateral clefts may vary in severity, depending on the state of the original defect, the care taken in the initial surgical procedure, the pattern of the patient's facial growth, and the effectiveness of interceptive orthodontic technique. Because each patient has a unique combination of deformities, their surgical reconstruction usually requires the modification and combination of several surgical techniques. Residual lip deformities after primary repair may be esthetic or functional and include scars, skin shortage or excess(vertical and transverse), orbicularis oris muscle malposition or diastasis. The key to accurate repair of secondary cleft lip deformities is a precise diagnosis. This requires observation of the patient in animation and repose. The quality of the scar is not the only factor determining the overall appearance of the lip. Observing the patient in the animated position is critical to assess muscular function. Factors that require precise analysis include lip length, the appearance of the Cupid's bow and philtrum, and nasal symmetry. Only after this detailed analysis can a decision be made as to wether a major or minor deformity exists. We report successful cases using various techniques for the secondary lip deformities.
