This thesis examines the origin, the change and the symbolic meanings of class representation, and offers a comparative study on the differences of class representation in the history of Korean and western costume on the basis of class representation methods and types shown from ancient times to 18C. In both eastern and western costume, the differences in status are commonly represented in the width and length of costume, color, textile, ornamental design, wearing, decoration, etc. The costume of noble class was wide and long, while that of common class was narrow and short so that it could be convenient for them to move around. Especially, from 16C to 18C in the west the costume of noble class was expanded to the extent that it was inconvenient for them to move around not only by skirt swelling by using hoop, but also by pad, ruff, lace, etc. This appears to show that they are not working class. Wearing and decoration of noble class were much more colorful, complicated and varied, while those of common class were simple and plain. In the west, the wearing of chiton and toga in Greece and Rome was different depending on social status. More specific look at the differences in class representation shown in the eastern and western costume reveals that the higher the rank, the more the women in both Gothic and Chosun period covered the body, thereby representing rank. In 18C, the women in both Rococo and Chosun period commonly showed excessive decoration and lavishness on their hair, and in this period the width of skirt was also commonly expanded to the longest extent, with a slight difference put aside.

The purpose of this study is to propose a solution for Goguryeo costume and its materials, colors, patterns, and accessories, which have not been dealt with in precedent studies and were treated as irrelevant subjects. The specific object of reconstruction with identification from the historical viewpoint is noble woman's costume(Yu and Gun) on the mural paintings of Jang-Cheon No.1 tomb in Jip-An province. As above, the reconstruction process of Yu(Jacket) and Gun(Skirt) worn by noble woman as depicted on the mural painting of the Baek-Hee-Gi-Ak-Do(百戱伎樂圖) in Jang-Cheon No.1 ancient tomb is suggested in this study. The most important issue for consideration was how to represent and exhibit it so that it resembles the mural painting as closely as possible. And the problems that arose at the time were the ratio and silhouette, which revealed disparities between the one on the mural painting and the costumes reproduced with identification from a historical viewpoint. The most difficult aspect of this work was due to the fact that the actual mural paintings were not available for verification. Therefore accuracy on details such as structure, materials, colors, patterns and accessory were difficult to obtain. So a further analysis of patterns, silhouettes, materials and colors are required for the precise representation of costume and dress on the mural painting.

The purpose of this study is to analyze sexual images in the 21th century men's fashion, including phenomenal formative changes and characteristics. Theoretical framework was developed based on literature reviews. Photo images were collected from collections presented in 2001 to 2008 on the internet sites. By focusing on sexual image. men's fashion design was analyzed. Since 21th century, men have expressed their own fashion sense and sexual image quite freely. Men's fashion has expanded its scope into region which are not exclusively of men's traditional fashion identity realm. The result of this study is as follows: First, Noble Dandyism is common among noble dandies whose desired image is luxurious, soft, and sophisticated. Second, Bisexual Caportism is another appealing 'Youth is beautiful' trend of our modern age. Beyond age and gender, modern people pay a special attention to the Caports look which aims to project an image of healthiness, dynamism, youth, and pure balanced beauty combined with fashion. Third, Macho Narcissism enjoys showing and exposing well-trained and beautiful bodies, compared to the old masculine image which was more known for expressing an authoritative and dominant strength. Fourth, Homme Fatale Vampicism seeks to accentuate deconstructed femininity and bare legs, matted make-up, long and curly hair, especially aims to emphasize sexual charms, which naturally makes its image more fascinating.

A measuring technique for tire-pavement interaction noise that uses a proposed noble close proximity(NCPX) method, which has been proofed in terms of the reliability and consistency of interaction noise measurement through several researches, equipped with surface microphones has been adopted in order to perform bridge deck pavement noise evaluations on four different pavement surfaces. Through field testing measurement of bridge deck pavement in Seoul inner ring road, the appropriate noise-measuring procedures have been used for evaluating the noise characteristics of four different surfaces. Measuring results show that tire-pavement noise levels vary depending on the surface types and vehicle speeds. Furthermore, the different characteristics of tire-pavement interaction noise can be found before and after the new surface construction of bridge deck pavements in terms of the 1/3 octave band analysis of vehicle speed.

The purpose of this study is to investigate the causes of clothes phenomenon of the ruling class women on the Heian period of Japan in the aspects of politics, economics, society, culture, and religion. The findings of the study are as follows. The main characteristics of the Heian period of Japan may include a rare sense of internationalism, low sense of nationalism, and frequent cases of political intrigue. However, noble culture, centered on royal court, was flourished and it enabled to develop sophisticated and graceful culture. During the Nara period and the Heian period (from $8^{th}$ to $12^{th}$ century), there were enormous changes in the clothes, starting from the mid $10^{th}$ century. The clothes of the ruling class in the Heian period underwent changes from the imitative clothes-imitating the clothes of the Tang age of China- to Japanesque clothes-adding the aesthetic consciousness of Japanese ruling class people. Particularly, the clothes of the ruling class women became massive, majestic, and decorative. The changed clothes had also features such as layered look, utilizing underwear as outer garments, using a wide variety of colors, and using hard and solid materials to make clothes. It can be concluded that the clothes of the ruling class people in the Heian period were affected by plural factors such as national and international political situation, economics, society, culture, and religion. The clothes were used by ruling class people as means of expressing their noble and sophisticated beauty, which led to produce humanistic beauty. The Heian period can be described as an era of the highest reach of humanity.

Characteristics of hydrocarbon selective catalytic reduction of NOx using various noble metal catalysts were investigated. The best active metal is Pt, supports are $CeO_2$ and $TiO_2$ by strong interactions between active metals, and 55% of conversion rate of NOx is shown. Pd, Rh and Ag catalysts presented a conversion of less than 20% as active metals, and supports also showed the poor activity compared to $SiO_2$ and $ZrO_2$. Experiments were performed with different types of reducing agents, amount, concentration of oxygen and space velocity in order to investigate the performance of catalysts according to operating conditions. The results confirm that the methane is better than propane as a reducing agent, and as the ratio of methane/nitrogen oxide increases, the catalytic activity increased, as the concentration of oxygen increases and space velocity decreases, the performance of catalysts increased.

In the reversed-phase ion-pair high performance liquid chromatographic (RPIP-HPLC) elution behavior of noble metal-thiacrown ether complexes, the effects of the concentration of ion-pairing reagent and kind of ligands were studied. It was found that the less the number of atoms in the ring of the thiacrown ether molecule was, the larger the selectivity was, and the elution mechanism of the complexes was explained due to the formation of ion-pair when the concentration of sodium dodecyl sulfate (SDS) in mobile phase was lower than 10 mM and due to the formation of micelle when the SDS concentration was higher than 10 mM. As a conclusion, separations of the noble metal-thiacrown ether complexes in an optimum separation condition were accomplished successfully and the method was proved to be an useful one for the separation and determination of Ag (Ⅰ) ion in a black-white photographic fixing solution.

This study examined the document Shaemirok, which recorded the daily lives of people from Jangsoo (長水), Junrado to Pyeongang (平康), Gangwondo, from 1591 to 1601. This book represents the mid Josun dynasty Noble Lineage's diary together with Muk-Jae (默齋日記). This study analyzed the Shaemirok of Noble lineage's seasonal food and traditional Korean food through the lens of the Shaemirok. The Shaemirok recorded that Josun people practiced the Julsa (節祀) and Julshik (節食) during the spring, as follows: Sakil (中和節) five times on February 1, Dapchungil (Samjiknal) six times on March 3, Hanshikil five times on March 8, and Deungsuk (Chopile) three times on April 8. Samjiknal on March 3, which is mentioned six times, is the spring Julsa and Julshik that show up most frequently within the Shaemirok's records. The Shaemirok recorded that Josun people, practiced the Julsa and Julshik during the summer, as follows: Danyang (Danoh) eight times on May 5 Youdoojul six times on June 15, Chilsuk five times on July 7, and Bakjoong five times on July 15. Dangohjul on May 5, which is mentioned eight times, is the summer Julsa and Julshik that show up most frequently within the Shaemirok's records. The Shaemirok's author recorded Julsa and Julshik practiced in the autumn eight times annually. Joongangjul, which is mentioned six times, is the autumn Julsa and Julshik that show up most frequently within the Shaemirok's records. Shaemirok recorded that Josun people practiced the Julsa and Julshik during the winter, as follows: Dongji during November, Sul on January 1, and Daebohrum on January 15 Dongji and Sul, Daebohrum are mentioned eight and seven times, respectively, in the Shaemirok. The people of the Four Main Families of the mid-period Josun practiced more Julsa and Julshik in the winter than in any other season. The Josun people stored the most food during winter, thus had the highest abundance of food. This seasonal factor explains Dongji and Sul, Daebohrum's unusual frequency with which they were celebrated.

This research project focused on the production of hydrogen through ammonia decomposition reactions while investigating how the reactivity of this process varies when employing different catalysts. Several metal oxide supports (Al₂O₃, La₂O₃, CeO₂) were utilized as catalysts, with active metals from both the transition metal group (Co, Ni, Fe, Cr, Cu) and the noble metal group (Ru, Rh, Pd, Pt) impregnated onto these supports. Furthermore, the study examined how the reactivity evolves with changes in reaction temperature when employing the prepared catalysts. Additionally, the research delved into the distinctive activation energies associated with each of the catalysts. In this research, In the noble metal catalyst system, the order of high activity for ammonia decomposition reaction to produce hydrogen is Ru > Rh > Pt ≈ Pd. In the transition metal catalyst system, the order of high activity is Co > Ni > Fe > Cr > Cu.
