In order to preserve the Korean traditional gold foil, to develop as Korean traditional textile art by utilizing in modem fashion for textile industry, and to examine utility of the material which can be used in the modem wearing, interior goods and fashion terms, Textiles Applied Korean Traditional Gold Foil were developed. The results are as follows: First, important factors of the gold foil image should be extracted as materials quality, color and pattern, and modem and practical qualities should be proceeded when developing the image of the gold foil into modem quality material. Second, since gloss of fabric developed by a traditional method is somewhat strong, uniformity being a little bit low for hand-made manufacturing, and practical quality is low for high cost, deletion of the gold foil, etc. So it hasn't been appropriate for studying modem fashion material. Third, Jacquard weave has been examined as the most appropriate method in order to present the gold foil image among a number of textile manufacturing techniques Fourth, considering factors deciding the image of the gold foil and a sense of beauty of modem society, gloss of the foil has been lessened by expressing pattern to lower traditional quality and primary color. Fifth, pattern motives of developed materials have been extracted tram traditional gold foil patterns, and materials have been chosen considering of concepts and motives, and dragon pattern, crane pattern and bat pattern, Sixth, wearing, pin-up works, bed linen, fabrics for chairs, ties, bags, shoes, umbrellas, etc. are produced with the developed materials, and practical use and modern quality have been examined. The result is very satisfactory.

In reality, the distinction between the Korean traditional culture and the cultures of other countries is at a delicate boundary. Additionally in the wake of the recent socio-cultural confrontation between Korea and China, it has become necessary to establish the foundation and area of Korean traditional culture and to actively utilize the importance of improving awareness of Korean traditional culture. To reorganize the reckless use of the gold foil pattern shown in the rental hanbok, data on the museum's collection of gold leaf patterns were collected and analyzed. Based on the gold foil, Gilsang characters such as Phoenix pattern, Crane pattern, Bat pattern, Flower pattern, Fruit pattern and recovery advice were extracted through references. The traditional gold foil pattern was reconstructed and relocated to design the gold leaf patch. Based on the collection and analysis of the museum's relics, the Wonsam & Daedae, Dangeui, Sranchima, Sagyusam, Jeonbok, Bokgun, and Daenggi were produced. Therefore, we present the possibility of producing gold foil and modern methods for producing gold foil using laser cutting techniques that can express refinement and complexity well, and gold foil thermal transfer paper with retouchable effects. Additionally, we would like to reflect upon the practicality and the convenience to modern people by considering the complexity and hassle of the traditional gold foil production process, and the disadvantages of processes that require relatively longer time. It intends to help revitalize the market of Korean traditional clothing and fashion products.

Those records indicate that Jik-geum Hyoong-bae fabric was imported from China and its period was during the fourteen and fifteen century. Gold threads used in three Jik-geum Hyoong-bae artifacts were all wrapped gold thread and gold thread of Danryeong from Young-dukdong, Yong-in, did not have a base, but instead the gold foil itself was attached to the silk cord. Such form of artifact had never been discovered before in Korea. Wrapped gold thread of Seoknamdong's basis was presumably bamboo paper. Three Jik-geum Hyoong-bae have the same weave structure. The ground is woven in a warp-faced 5-end satin weave. The pattern is brocaded with supplementary gold wefts. Supplementary gold wefts are composed of 1/4 twill binding by the odd number pairs of warps within every group of 10 pairs of warps. All of the Jik-geum Hyoong-bae textile were designed and weaved according to the overlapped collared costume's structure. This is also known as 'Jik-seong-pil-ryo'. One symmetric collared jacket excavated in Seok-namdong, Incheon, only has the right half of Hyoong-bae in the front. This is because symmetric collared jacket was made from overlapped collared costume. Tiger and peacock are the main patterns of Jik-geum Hyoong-bae which have realistic and free screen composition and this shows a huge difference to the later generation's standardized Hyoong-bae pattern.

Zinc Phosphate Cement hand been used for about more than 100 years in luting of cast gold inlay. But many scientists had been trying to develop the new form of luting agent because the ZPC hand shown the lack of adhesiveness on the tooth structure and the toxicity to the pulp tissue. Recently many researches about the surface treatment of the cast body are being done to increase the adhesion of cement to it. The conventional Class I gold inlays were fabricated in the 20 permanent molars. After the internal surface of the cast body was sandblasted with $Al_2O_3$ particles and was tin-plated, the inlays were cemented with adhesive cement [G I cement and resin cement(Super-Bond & $Panavia_{EX}$)] and the evaluation on the adhesion pattern, adhesive strength and the fracture pattern of the adhesive cast gold inlay was compared to that of the cast gold inlay cemented conventionally with ZPC. The results were as follows : 1. The surface roughness of the cast body was increased significantly after sandblasting with the $Al_2O_3$ particles and the tin oxide layer, which was consisted of round particles, came into being. 2. The bond strength was in the order of Super-Bond, ZPC, Fuji I, $Panavia_{EX}$ group. The group cemented with Super-Bond showed statistically greater strength than the other groups(p<0.05). 3. The group cemented with ZPC was fallen apart by principal adhesion failure and that with Fuji I was by complete adhesion failure. But the group with Super-Bond showed pricncipal cohesive failure pattern and in the group with $Panavia_{EX}$, complete cohesive fracture pattern was shown and small protion of tooth structure was fractured out with cast body and the fractured surface showed the figure just as the enamel prism. 4. Various gaps were shown at the pulpal side regardless of little gap at the side walls of the cavity in all groups. Only the Super-Bond was attached to the tooth structure and the other cements were detached from both the tooth and the cast body.

The purpose of this study was to compare the casting problem and corrosion behavior in two types of HL Hexed abutments of the Steri-Oss system ; gold/plastic coping and gold coping. The anodic Polarization behavior, the galvanic corrosion between abutments and Type III gold alloys, before and after casting were analyzed, and the crevice corrosion of casting samples was analyzed with the CPPT test and the SEM. The results are as follows : 1. Anodic polarization behavior of samples ; Before casting, gold/plastic coping and gold coping was shown to have a similar corrosion pat-terns. Type III casting gold alloy was shown to have a lower corrosion potential and passivation film. Corrosion potential of the case of gold/plastic coping after casting was higher than that of gold coping, but the region of passivation film for gold/plastic coping was smaller than that of gold coping. 2. Galvanic corrosion behavior of samples ; Contact current density between casting gold alloys and gold/plastic before casting was higher than that between gold coping and casting gold alloy Galvanic corrosion of samples after casting was shown to have similar contact current density 3. Crevice corrosion behavior of samples ; Crevice corrosion resistance of casting sample using gold coping was lower than that of cast-ing sample using gold/plastic coping, and a severe corrosion pattern was observed at the abutment-casting gold alloy interface by the SEM.

As to the reflection electrode of LCD (liquid crystal displays), silver-copper-gold alloy (hereafter, it is called as ACA (Ag98%, Cu1%, Au1%)) is an effective material of which weathering resistance can be improved more compared with pure silver. However, there is a problem that gold remains on the substrate as residues when ACA is etched in cerium ammonium nitrate solution or phosphoric acid. Gold can not be etched in these etchants as readily as the other two alloying elements. Gold residue has actually been removed physically by brushing etc. This procedure causes damage to the display elements. Another etchant of iodine/potassium iodide generally known as one of the gold etchants can not give precise etch pattern because of remarkable difference in etching rates among silver, copper and gold. The purpose of this research is to obtain a practical etchant for ACA alloy. The results are as follows. The cyanogen complex salt of gold generates when cyanide is used as the etchant, in which gold dissolves considerably. Oxygen reduction is important as the cathodic reaction in the dissolution of gold. A new etchant of sodium cyanide / potassium ferricyanide whose cathodic reduction is stronger than oxygen, can give precise etch patterns in ACA alloy swiftly at room temperature.

The purpose of this study is to figure out the types and characteristics of golden decoration technique out of various techniques of expressing patterns on the costumes. This study reviews both costumes decorated with gold in the relics of Chosun dynasty and literatures focused on domestic and Chinese documents and records. The types of decoration technique using gold include JigGeum (brocade technique), InGeum (gold powder and flake attaching technique), and GeumSaJaSu (embroidery technique). The JigGeum is weaved using golden thread instead of silk thread in order to express patterns. The InGeum technique is to attach gold or silver powder or thin gold or silver flake on the surface of the fabric. The GeumSaJaSu technique is to embroider with gold thread on fabrics. 82 pieces of costumes made using gold in Chosun dynasty era are analyzed. The results follows; In terms of types of technique, is shown to take the majority; JigGeum (43.90%), InGeum (30.49%), GeumSaJaSu (23.61%). Looking at the patterns used by the types, plant pattern and letter pattern are mostly used for both the JigGeum and the inGeum. In terms of the characteristics by their uses, the InGeum is used for court dresses (52%). It is also used for ordinary dresses (12%) and for other purposes (36%). It is mostly used in the court dresses in the late period of Chosun dynasty era. The JigGeum is used for ordinary dresses (47.22%), for court dresses (44.44%) and for other purposes (8.34%). It is evenly used for court dresses and ordinary dresses.

This study aims to expand the scope of use for relics by applying the patterns and characteristics of embroidered fabric pieces, such as gold foil, excavated from the Mireuksa Temple Site in Iksan for fashion products. The artifact was a ra decorated with flower and vine patterns, embroidery using gold and red thread, and the unique stitching of Baekje. The pattern was reconstructed, as the embroidery was not well-preserved. This study used two types of gold-foil techniques: laser-cut and stone-stamp gold foil. Considering practicality, the gloss, toughness, custom production possibility, and design implementation were emphasized. The form of the laser-cut gold foil could be transformed; however, a recognition problem with the machine increased the thickness of the stitching. It was used for half-finished goods and commercial casual fashion. The stone-stamp gold foil was finely implemented, but the design was difficult to change. It was used for half-finished silk fabric for making hanbok po and lattice-patterned silk skirts. Applying the developed gold foil to suitable clothing can further enhance the effect.
