Hanging boards of the Joseon royal court are hung on buildings related to the royal family, such as palaces and Jongmyo Shrine, to show the hierarchy and character of the building. In addition, the manufacturing method and materials are recorded in the royal protocols of the Joseon Dynasty, so it is an important material for studying the manufacturing method and material changes at that time. However, the hanging boards were restored several times due to fire or war, and it is presumed that there is a change in the original form and material of the hanging boards. In particular, many hanging boards of the Joseon royal court were written with calligraphy by kings, so there are many forms consisting of gold letters on a black background. This study tried to analyze the pigments remaining in the letters of 44 of the Joseon royal hanging boards, which are presumed to be gold letters, and to find out the changes in the hanging board production method and materials by referring to the analysis results. The letters of the hanging boards studied were classified according to the current state of the gold pigment and the detected components. As a result of the analysis of character pigments, 24 embossing techniques and 5 intaglio techniques were mainly detected with gold (Au), but 15 embossing techniques were detected with brass (Cu, Zn). Only blue-green substances, not gold pigments, remain in some of the hanging boards in which brass components were detected. A reproduction experiment was conducted because the pigments of the brass component were not recorded in the literature and were not currently used as Dancheong pigments. In the reproduction experiment, it was difficult to confirm the application and use of brass pigments due to the limitations of materials, but it is judged that research on the timing and method of using brass pigments is needed in the future.

Symbolizing holiness, wealth and power, golden color was most effective to express the absolute power of royal family and aristocratic society as well as the beauty of magnificent and brilliant authority. Such golden color was understood as the artistic color formed in the dictatorial society as well as the society under the rule of absolute monarch. Thus, it has been used in the costume that symbolizes nobleness, holiness, brilliancy, ethnicity and future-oriented property. In this sense, the image of golden color shown in contemporary fashion was analyzed as follows in this research: First, showing the future-oriented image, golden color expresses avant-garde, cyber and cosmic future-oriented image by using diverse new materials which introduce the state-of-the-art technology sense in addition to metallic textile. Second, getting hint from the ethnic costume of many countries around the world such as brilliant embroidery using golden-thread, ornament with exaggerated technique such as gold foil, mark and character in peculiar tint, the ethnic image of golden color expressed the peculiar color or materials of ethnic costume, handicraft details, etc in golden color. Third, since golden color is expressed in ostentatious image to which elegance and luxuriousness that looks like the work of haute-couture costume of royal family or sensuality that voluptuously expresses the beautiful body line of women are added, the viewers are enchanted or attracted.

Purpose: HCD ion plating apparatus by hollow cathod discharge method was fabricated and TiN films were deposited on stainless steel by this apparatus with increasing in $N_2$ gas flow and the fine color changes of TiN films were analyzed. Methods: The spectroradiometer and spectrophotometer were used to observe optically the fine color changes of TiN thin films, and XPS was used to analyze the compositions of TiN thin films with increasing in $N_2$ gas flow. Results: The color coordinate of TiN thin film with $N_2$ 120 sccm gas flow showed (0.382, 0.372) which had the mixed colors of gold and silver, and the color coordinate changed to the increasing value of (x,y) with increasing in $N_2$ gas flow which indicated the deep gold color. It was found that the slopes of the reflectances at 550nm were increased with increasing in $N_2$ gas flow. And from the Ti scans using XPS, it was found that the peak heights of 455 eV derived from TiN composition were increased with increasing in $N_2$ gas flow, while the peak heights of 459 eV from $TiO_2$ composition were decreased. Conclusions: The results obtained above were that the color of TiN film with 120 sccm $N_2$ gas flow had been observed from the mixed color of silver and gold due to TiC, $N_2$, TiN on the surface and TiN, $N_2$ inside film, and the color of TiN films changed a deep gold color with increasing in $N_2$ gas flow due to increasing TiN composition.

The Nongso tomb of Sunchang was built in a relatively deep place; hence there was little damage from grave robbers. The tomb was completely filled with a large amount of charcoal, and therefore the wooden coffin was excavated in relatively good condition. On the basis of the structure of the tombs, excavated artifacts, and radiocarbon dating results, the tomb is estimated to be from between the late Goryeo and the early Joseon period. The wooden coffin excavated is double-layered structures consisting of an outer coffin and an inner coffin. The outside of the wooden coffin is thickly lacquered and decorated with yellow letters and white motifs. An analysis of the pigments' components revealed that the major component of the letters was gold (Au) and the major component of the motifs was silver (Ag). The coffin lacquer had three layers: a pigment layer, a yellowish-brown layer, and a black layer. The wooden bases of the coffins were painted with a black substance, such as soot, as mineral elements were not detected in the black layer. The yellowish-brown layer is presumed to be refined lacquer. From the analysis of the structure of the layers and pigments, we can estimate the method was adopted for making lacquer for wooden coffin. It is assumed that the method used gold leaf and gold powder. The form of the pigment and the internal structure are likely to be gold leaf, but the shape of the surface letters appears to have been formed using gold powder. This study will serve as important information for understanding lacquer making techniques at the time of the tombs' construction by confirming the making method through reproduction experiments using gold leaf and gold powder.

Purpose: TiN films were deposited on sus304 by unbalanced magnetron sputtering system which was designed and developed as unbalancing the strength of the magnets in the magnetron electrode. The color and hardness of deposited TiN films was investigated. Methods: The cross sections of deposited films on silicon wafer were observed by SEM to measure the thickness of the films, the components of the surface of the films were identified by XPS, the components of the inner parts of the films were observed by XPS depth profiling. XPS high resolution scans and curve fittings of deposited films were performed for quantitative chemical analysis, Vickers micro hardness measurements of deposited films were performed with a nano indenter equipment. Results: The colors of deposited films gradually changed from light gold to dark gold, light violet, and indigo color with increasing of the thickness. It could be seen that the color change come from the composite change of three compound,$TiO_{x}N_{y}$, $TiO_2$, TiN. Especially, the composite change of$TiO_{x}N_{y}$ compound was thought to affect the color change with respect to thickness. Conclusions: Deposited films had lower than the value of general TiN film in Vickers hardness, which was caused by mixing three TiN, $TiO_2$,$TiO_{x}N_{y}$ compound in the deposited films. The increasing and decreasing of micro hardness with respect to thickness was thought to have something to do with the composite of TiN in the films.

The purpose of this study was to compare surface hardness between titanium-nitride coated crowns (TiNCs) and stainless steel crowns (SSCs), and to evaluate the corrosion resistance and color sustainability of TiNCs. Ten TiNCs and 10 SSCs were used for the hardness test. Measurement was performed 30 times for each type of crowns, and the mean values were compared. Metallic raw material plates (before being processed into crowns) of TiNCs and SSCs were prepared for the corrosion resistance test. The total amounts of metal ion releases in the test solution were detected by inductively coupled plasma-optical emission spectrometry. Five TiNCs were subjected to the color sustainability test by applying repetitive brushing forces. The mean hardness values of TiNC group and SSC group were 395.53 ± 105.90 Hv and 278.70 ± 31.45 Hv respectively. Hardness of TiNCs were significantly higher than that of SSCs. The total amounts of metal ion releases from the materials of TiNCs and SSCs satisfied the criterion in International Organization for Standardization 22674. The results mean that TiNCs and SSCs were not harmful in an acidic environment. The golden coating was stable against the repetitive physical stimulations for a given period time.

In order to investigate the color variation and the solubility limit in wagnerites by metal ion substitution, wagnerite ($A_2XO_4Z$) was synthesized and then, substituted by coloring metal ions, especially $CO^{2+},Ni^{2+}$ and $Cu^{2+}$ ions. When calcium was replaced with Mg, Co, Ni and Cu divalent ions, solid solutions were formed with a limited solubility. Single phase wagnerites were synthesized by the substitution of Ca with Mg and Co, and their colors were white and purple, respectively. Substitutions with $Li^+$ were succeeded in the specific composition and the substitution of vanadium for $X^{5+}$ were attempted, resulting in the wagnerites of dark purple, dark gold and light yellow colors. The substitution of chlorine was, also, attmepted for the fluorine site.

In this research, TiN films has been grown to the stainless steel substrate by ion beam assisted deposition. TiN film was grown to the nitrogen atmosphere of around $10^{-15}$ Torr with Arion bombardment. The chemical composition, color and adhesion of TiN films were examined as a variation of En(ion energy per atom). The N/Ti ratio increased linearly as the increase of En and saturated around 1.2 at high En. As a results, the bright golden color was obtained when En reached a certain value of Ecn. As a results, the N/Ti ratio is about 0.9.

This thesis aims to examine the symbolism of color in the clothing of women, focusing on the protagonist of the movie Elizabeth: The Golden Age (2007). At the beginning of the movie, the Queen wears gowns with cartwheel ruff and wheel farthingales, symbolizing the attempt of establishing a powerful majesty. However, the Queen falls in love with Walter Raleigh and her clothing comes to emphasize femininity displaying her cleavage. Later on, her clothing indicates charismatic authority as she prepares for the Spanish war. At the end of the movie, the Queen who led the the country to victory in war puts on a luxurious gown with butterfly wings that reminds of a fairy queen. The colors of the Queen's clothing are categorized into three groups. First, the color red represents two opposite allegories. The positive image of red denotes Christ's blood, the love of God, and noble status of the Queen's image as a savior of England. On the other hand, red represents lewdness and evil which insinuate that the Queen is being attacked on her religious and political genuineness. Second, the color blue represents Saint Maria, chastity, and divinity. Third, the color goldw and white represent the Queen's ideals which are chastity as a virgin Queen and divinity.
