This research aims to suggest methods to improve object tracking performance by combining CAM shift algorithm with 8-way search window, and reduce arithmetic operation by reducing the number of frame used for tracking. CAM shift has its adverse effect in tracking methods using signature color or having difficulty in tracking rapidly moving object. To resolve this, moving search window of CAM shift makes it possible to more accurately track high-speed moving object after finding object by conducting 8-way search by using information at a final successful timing point from a timing point missing tracking object. Moreover, hardware development led to increased unnecessary arithmetic operation by increasing the number of frame produced per second, which indicates efficiency can be enhanced by reducing the number of frame used in tracking to reduce unnecessary arithmetic operation.

This paper presents a hole-filling method using extrapolated spatio-temporal background information to obtain a synthesized view. A new temporal background model using non-overlapped patch based background codebook is introduced to extrapolate temporal background information In addition, a depth-map driven spatial local background estimation is addressed to define spatial background constraints that represent the lower and upper bounds of a background candidate. Background holes are filled by comparing the similarities between the temporal background information and the spatial background constraints. Additionally, a depth map-based ghost removal filter is described to solve the problem of the non-fit between a color image and the corresponding depth map of a virtual view after 3-D warping. Finally, an inpainting is applied to fill in the remaining holes with the priority function that includes a new depth term. The experimental results demonstrated that the proposed method led to results that promised subjective and objective improvement over the state-of-the-art methods.

Religion affects all the dimension of human beings, and at the same time it forms one dimension of human beings. Costume Is considered as a result that reflects the phases of the time and the characteristics of a wearer. Costume, also, has been influenced by religion that has led one's belief, social spirit and culture for a long period of time. The Eastern aesthetics has expanded the area of thoughts with the concepts that originated from Buddhism, Taoism, and Confucianism. Among the concepts, Non-Dualistic Theory is the core idea of Buddhism.'rho theory contains the moaning that one should not lean to one side between existence and nonexistence and should not be obsessed with the center. It was the most powerful Buddhistic idea that had an influence on Asian aesthetics. Korean traditional costume is not an exception. This study has a significance that it was conducted to understand the relation between religious principle and traditional custom through mainly using documentary records. The formative characteristics of Korean traditional costume influenced by Non-Dualistic Theory ran be summarized as non-structure like, indeterminate forms, amorphousness and anti-decoration such as plainness, temperance and achromatic color. Aesthetic value was expressed through 'the aesthetic of emptiness', 'the aesthetic of hiding', and 'the aesthetic of nature'. Although the appearance of a religious symbol can change, an essential element in religion lasts as human society remains. Although our clothing culture has converted to western style, Korean traditional aesthetics is placed deep inside of 'the Koreans' spirit and has a consistent effect on our overall culture of clothing.

Woman leadership has been remarkably highlighted with women's accelerating entry into society. Domestic and overseas interests about political leaders began with the age of media and they are rapidly spreading worldwide with the development of internet, SNS and blog. Along with this phenomenon, exposure of images has been remarkably increasing and fashion has been also used as a political strategy. However, the research on woman political leaders has been insufficient so this study selected Geunhye Park, Michelle Obama and Hillary Clinton as representative woman leaders for the research. 149 pictures of Geunhye Park, 171 pictures of Michelle Obama and 124 pictures of Hillary Clinton from the articles containing their pictures from Jan. 2002 to Dec. 2013 were analyzed, focusing on their gender. The three woman political leaders' typical images of femininity, masculinity and androgyny were categorized respectively and the period and works in which those images had been expressed were reviewed. Also, fashion styles of the images pursued by each gender were analyzed through their color, material, silhouette, design point, items and accessories. As a result, Geunhye Park had femininity image at the beginning and had masculinity image when she did election campaigns, which led to her current image of androgyny. Michelle Obama uses the image of femininity, masculinity and androgyny simultaneously. It was found that Hillary Clinton emphasized the image of masculinity and androgyny but she emphasizes femininity image these days.

The 21st century is the age when a sensational image has more explanatory power and can deliver a more powerful message than a message consisting of logical thinking. Powerful visual images create a big impact on many people throughout the world, overcoming linguistic barriers and even replacing language as a means of communication. In the fashion field, the concept and power of visual images within the new multimedia of the 21st century are becoming increasingly important. In recent years, other than the above methods, videos, movies and animation features have been produced directly to enhance visual effects and attempts are increasing to use these new tools as communication methods. This study focuses on animation contents that have been used in the fashion industry to overcome prejudice of luxury international brands that feature images that emphasize value, quality and heritage. The purpose of this study is to focus on the specific character of fashion animation in order to overview the concept of 21st video fashion communication and to show how the collection concept that includes color and detail places an emphasis on visual images. Analysis of previous research, theoretical research through literature and case study on Prada fashion animation led to the following conclusion. The common features of two different Prada fashion animation show that both animation have the following features in common : realism, dramatic impact and convergence for expression methods, and creativeness, hybrid and a happy ending for contents. Beginning with this study, I believe that various angles of interest and concern about communication in the fashion world, which is a social and cultural phenomenon that changes rapidly, can be will be looked at and learned from.

This study proposes a pixel-patterning method for organic light-emitting diodes (OLEDs) based on thermal transfer. An infrared lamp was introduced as a heat source, and glass type donor element, which absorbs infrared and generates heat and then transfers the organic layer to the substrate, was designed to selectively sublimate the organic material. A 200 nm-thick layer of molybdenum (Mo) was used as the lightto-heat conversion (LTHC) layer, and a 300 nm-thick layer of patterned silicon dioxide (SiO₂), featuring a low heat-transfer coefficient, was formed on top of the LTHC layer to selectively block heat transfer. To prevent the thermal oxidation and diffusion of the LTHC material, a 100 nm-thick layer of silicon nitride (SiN_x) was coated on the material. The fabricated donor glass exhibited appropriate temperature-increment property until 249 ℃, which is enough to evaporate the organic materials. The alpha-step thickness profiler and X-ray reflection (XRR) analysis revealed that the thickness of the transferred film decreased with increase in film density. In the patterning test, we achieved a 100 ㎛-long line and dot pattern with a high transfer accuracy and a mean deviation of ± 4.49 ㎛. By using the thermal-transfer process, we also fabricated a red phosphorescent device to confirm that the emissive layer was transferred well without the separation of the host and the dopant owing to a difference in their evaporation temperatures. Consequently, its efficiency suffered a minor decline owing to the oxidation of the material caused by the poor vacuum pressure of the process chamber; however, it exhibited an identical color property.

In fashion, there are various cultural aspects that exist in complexity, where according to the era, even fashion items newly develop and prevail into various designs in the organic function with reality of related cultural phenomenon and aesthetic aim. Among the fashion items, the shoe is historically considered as the shield from lust and also the provision of praise against the most emotional incitement. Mankind has started wearing shoes out of the functional purpose of protection since the ancient Egyptian times. Thereafter humankind has been creating shoes artistically in respect to shape, color, and quality of material, etc, as an expression of aesthetical awareness and introspective desire for beauty. As modern fashion increasingly regards the total fashion image much more important than each items consisting the whole outfit, the role of shoe became essential more than ever. Contrary to its relative importance, little academic attention was given to this area yet, while prestigious museums and galleries in Europe and the USA have held exhibitions of shoes in view of both historical and artistic aspects. This study aims to make a historical inquiry of western shoes. through which their aesthetic values can be drawn. Literature on this subject including aesthetics, history of costume and arts were referred. Fashion magazines and catalogues were investigated for additional information. The process and results of this study are meant to be a suggestion not only to further studies but also to artistic and creative shoe design. Originated for the functional purpose, shoes have evolved in various shapes with different meanings attached to it. When the technological development made the satisfaction for functional needs possible, the intrinsic attribute, the aesthetic value was pursued. The historical contemplations of shoes from Egyptian times to the 1990's led to the results that the intrinsic aesthetic value of shoes can be summarized as follows: 1) protection and extension of body, 2) need for decoration, 3) erotic expression, 4) symbol of dignity and class, 5) fashion.

The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly. Egg weights and egg quality were measured daily. Corticosterone treatment resulted in a remarkable increase in feed intake and sharp decrease in egg production compared with control (p<0.05) whereas body weight remained unchanged. Decreased albumen height, but no changes in egg weight, led to decreased Haugh unit (p<0.05). Corticosterone caused elevated eggshell thickness (p<0.05) without altering weight and strength, suggesting possible changes in shell structure. Yolk color and redness were increased by corticosterone (p<0.05) but lightness and yellowness were either not changed or inconsistent over the time period of measurements. Increased concentrations in plasma were also found for corticosterone, glucose, cholesterol, creatinine, uric acid, albumin, aspartate aminotransferase, creatine kinase, lactate dehydrogenase, total protein, and amylase (p<0.05), suggesting that corticosterone increased protein breakdown, renal dysfunctions and pancreatitis. Together, the current results imply that dietary corticosterone affects egg quality such as yolk colors and shell thickness, in addition to its effects on feed intake and egg production.

The purpose of this study is to grasp creation background and social position of courtesan which is treated in social and cultural context and its effect on fashion and research representative courtesans from ancient hetaera to the 19th century and their costume characteristics. Its another purpose is to analyze the costume of Violetta, who is a heroine of opera and its costume characteristic as a courtesan. Most Courtesan clothing were made from bright color, silk and lace which were light, or transparent materials. Using silk and cashmere which were the symbols of class, she took the cutting edge fashion and struggled to break the social barriers. The clothing which the Courtesan wore always became a gossip among people and popular to the designers who could show their creativities because the Courtesan boldly wore the cloth like movie actresses or stars. The Courtesan who led the fashion not only showed the fashion as a simple expression of the beauty but also as a socio-cultural phenomenon which reflected their social awareness with arts, and changed according to the situations of the time and people. Violetta's party dress which was shown in the first and third acts of showed the shoulders and chest because of the deep and wide cut decollete, the waist was tightened with a corset as much as possible, and the opulent hips were inflated by the crinoline so when they walked it was swaying. Also it was decorated with splendid materials such as silk and lace, and sparkling jewels, fans, and neckless and even in case of the general clothing in the second act, it was decorated with braids and lace, frills and ribbons. In the third act, the weakness of the sick woman who was closing her life as the splendid Courtesan was emphasized by using colors of white and light purple and thin transparent materials.

Objective: The purpose of this study was to observe stress distribution and displacement patterns of the entire maxillary arch with regard to distalizing force vectors applied from interdental miniscrews. Methods: A standard three-dimensional finite element model was constructed to simulate the maxillary teeth, periodontal ligament, and alveolar process. The displacement of each tooth was calculated on x, y, and z axes, and the von Mises stress distribution was visualized using color-coded scales. Results: A single distalizing force at the archwire level induced lingual inclination of the anterior segment, and slight intrusive distal tipping of the posterior segment. In contrast, force at the high level of the retraction hook resulted in lingual root movement of the anterior segment, and extrusive distal translation of the posterior segment. As the force application point was located posteriorly along the archwire, the likelihood of extrusive lingual inclination of the anterior segment increased, and the vertical component of the force led to intrusion and buccal tipping of the posterior segment. Rotation of the occlusal plane was dependent on the relationship between the line of force and the possible center of resistance of the entire arch. Conclusions: Displacement of the entire arch may be dictated by a direct relationship between the center of resistance of the whole arch and the line of action generated between the miniscrews and force application points at the archwire, which makes the total arch movement highly predictable.
