In order to improve the calculation speed of an integrating-sphere simulator based on a ray-tracing method, parallel processing with OpenMP directive was implemented into the simulator and the randomness of Monte Carlo method was guaranteed by utilizing a parallel random number generator. It was confirmed that simulation results obtained with more than $10^7$ rays showed good agreement with theoretical results within the error range of 0.5%, and that the calculation speed improved as the number of threads increased. Finally, the spatial response distribution functions of a real integrating sphere were simulated and compared with previous results.

In this study, the propagation characteristics and the fabrication tolerance of an optical wire in a flexible optical PCB were analyzed by using a ray-tracing method. It is found from the analysis that the sidewall angle of a core should be controlled within $1^{\circ}$ in order to maintain the propagation loss to less than -1 dB/mm, and that the bending radius of the optical wire should be larger than 5 mm in order to suppress the bending loss below -1 dB. In addition, it is confirmed that the lateral misalignment of ${\pm}15\;{\mu}m$, and the angular tilting of VCSEL of $6^{\circ}$ are allowable for the coupling loss of -1 dB.

This study researchers the libretto and the original novel of the opera to propose fashion styles and stage costumes for the opera, "La $boh\grave{e}me$." This article studied the meanings of the $boh\grave{e}me$ in the 1830's France and the characteristics of the $boh\grave{e}me$ that appeared in the original novel, "$Sc\grave{e}nes$ de la vie de $boh\grave{e}me$." The characteristics of bohemian fashion styles in the $Sc\grave{e}nes$ de la vie de $boh\grave{e}me$ were not normal, not related with trends, and not new. Before presenting the new fashion styles, this study examined the stage costume problems of La $boh\grave{e}me$ with five existing performance materials. In conclusion, this study proposed new stage costume designs that reflect more dramatic fashion expressions of the characters, expression on the passage of time, and contemporary fashion records.

The purpose of this study is to research the similarity and difference of color application in culture of Korea and China. The subject of this research is the costume color of Changgeuk and Beijing opera. First, a bibliographical inquiry includes the attributes of cultural color in Korea and China and the costume attributes of Changgeuk and Beijing opera. Second, this survey analyzes Munsell's 3 attributes(Hue, Value, Chroma), tone by extracted color data. The results of this study are as follows: 1. The cultural color factors of Korea and China are classified geographical factor, internal cultural factor and external cultural factor. 2. Changgeuk costume much more used high value and medium & low chroma for korean temperate climate. But Beijing opera costume prefers high-medium value and low chroma color, various ranges of color because of China huge land and various climates, as geographical factor. 3. Changgeuk costume much more used YR color(no-dyeing color) because of korean white robe preference. Beijing opera costume much more used R color than Changgeuk costume because of traditional preference of R color, as infernal cultural factor. 4. Changgeuk costume and Beijing opera costume show the practical use of ascetic cole. like as jade green. Ojungsaek much less used than Obangsaek by the theory of exponents of the five elements doctrine, as external cultural factor.

Historically, garments have been spontaneously made with human instinct in order to warm and decorate the body using textiles that have been made and used by various peoples in different cultures. Contemporary garments have been used as a means of warming as well as express individual personality and a desire to pursue beauty. They have a unique formativeness and a symbolic nature according to cultural phenomena that reflect a cultural outcome that expresses contemporary thinking and ideology as well as their aesthetic consciousness. This study globally promotes Chinese opera mask culture and proposes the possibility of creative thinking through the introduction of Chinese opera mask elements into contemporary fashion, expressing them as patchworks. In order to endow artistic value (required in contemporary fashion) this study creates works by analyzing and applying a formative sense seen in patchwork techniques and the characteristics of Chinese opera masks; in addition, it sought the possibility of new expressions in garment designs. The results obtained from the research involve the following. First, the introduction of the traditional patchwork technique to contemporary garments may be a dynamic theme of garment expression and exceed stereotypical ideas that enable the creation of designs attuned to the globalization era. Second, it was possible to pursue independent formativeness which is in harmony with a modern sense through the restructuring of the harmony of colors and practical characteristics found in patchworks. Third, it was possible to demonstrate their artistry and unique effect in the expression of contemporary garments by the expression of the analyzed results of characteristic patterns of Chinese opera masks with a patchwork technique in creating works. Results show that it is necessary to conduct research into a patchwork technique that applies diverse materials as a new method to develop contemporary garment design also as a creative design. In addition, if the analyzed results of the characteristic patterns of Chinese opera masks can be expressed with a patchwork technique, they may be able to exhibit a genuine effect along with the artistry of expression in contemporary garments; thereby, relevant follow-up research should be further continued.

The purpose of this research was to study the forms and styles of the costumes in the Peking Opera of China and to figure out the symbolism and aesthetic value of the costumes. The research was done using documentary Peking Opera, the costumes can be seen as a special kind of language which audience members can clearly understand it. Therefore, the spectators can understand instantly the sex, age, personality, and position of the character by seeing the style, color, and patterns of the costumes. As a result, one can call the costumes of Peking Opera, "picturizing costumes". The typical costumes are mangpao, pi, kao, xiezi, yi. Mangpao is the ceremonial robe often used by emperors and officials. It can be worn by lao sheng, xiao sheng and wu sheng. Bright yellow and apricot yellow colors are used exclusively by those who play the parts of emperors, foreign rulers, princes and the Monkey King. The next costume style to be discussed is Pi. Pi is the informal dress for the emperor, and young officials that are involved in civilian or military duties. The third costume style to be explored is Kao: the garment that a stage warrior wears when going into battle. This warrior can have three kinds of armor: the hard armor, the soft armor and the newly revised armor. Fourthly, the costume that is the most commonly worn, xiezi, is examined; it is the informal coat for every one regardless of one's age, sex, role, or level of nobility. Finally, the last of the typical costumes is Yi; this costume category includes numerous kinds of costumes, such as kaichang, baguaiyi, fayi, guanyi, yulinjia, kanjian, toupeng, jianyi, etc

The costumes (including mask) of the first World Master series of The National Changguk Company of Korea, Achim Freyer's 'Mr. Rabbit & Dragon king' is directly designed by Achim Freyer who was in charge of direction and stage design. The new form called Pansori opera is proposed for modernization of Korean traditional opera, it maintained the original form of music yet introduced play form of opera. The costumes and stage also promoted modernistic transformation while maintaining the original Korean form. The overall concept of 'Mr. Rabbit & Dragon king' costumes emphasizes comical effect by abstractness like childlike scribble. It expressed characteristic of characters diversely through exaggeration and expansion while maintaining original form of Hanbok, used surface of costumes as a drawing board, and created flat and geometrically transformed silhouette. The complicated characters was caricatured like everyone is doing mask play by using masks, and it still maintained sophisticated oriental color with modern application of five cardinal colors. It may seems it just mixed our traditional elements like a hint of humor, however, it could be known that it introduced various techniques in it to deliver new subject while maintaining the original form of 'Mr. Rabbit & Dragon king'.

Besides, the costume in performing art which play a major role in opera's visual impact, characterize figures, set the tone for performance and greatly contribute to the perfection of the stage. Under these circumstances, the study developed designs of stage costumes and built a full-scale production of the Magic Flute, one of three greatest Mozart operas. The opera based on a fiction, is still popular today since it is a fantastic fairy tale introducing moral and ethical lessons. The play's background itself is Egypt. But due to its fairy-take-like storyline, it has been performed focusing on various concepts rather than on costumes prepared through background research. As such, this study conducted research on designs of stage costumes that contains the element of Egypt and also take athleticism and comfort into consideration. The results derived from the study were as follows. First, traditional dresses of ancient Egypt were used as a basis while adding some modem touch in terms of forms or colors, which resulted in a new design. Second, a variety of images were captured using textures and colors that fit the characteristics of attributes of the figures. Third painting techniques were used to help highlight the symbolic image of Egypt-simple, not heavy and extravagant-with fairy-tale-like fantasy.
