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.

The objectives of this research were to find out factor of image perception about women's accessories, to test differences in image evaluation according to materials and forms, and to investigate differences in image evaluation according to total stimuli. The results of this study were as follows. First, the accessory image factor derived four categories: attractiveness, prettiness, gorgeousness, and soft. Second, in two dependent variables, material and form had no significant interaction effects on attractiveness, prettiness, gorgeousness, and soft. In main effect, there was a significant difference of attractiveness, prettiness, and gorgeousness according to form. That is, the lined types had better prettiness and gorgeousness than the attachable ones. There was a significant difference of attractiveness, prettiness, gorgeousness, and soft according to materials. That is, pearl was considered to be the most attractive and soft. Plastic was evaluated image of least fashionable and soft, gold did image of the least gorgeous. Third, the attractiveness of attachable diamond earring was evaluated the highest, and the lined plastic ones did the lowest. It was evaluated and concluded that the lined plastic ones is considered the prettiness and most gorgeous where as any earring with attachable gold earring were considered the least prettiness and gorgeous. The attachable silver or pearl earrings were considered to be projecting the softest image whereas the lined gold and attachable plastic ones the opposite.

In this study, HU(hounsfield unit) value of CT generated by dental prosthesis was measured according to the type of metal when PET-CT was performed, and the degree of distortion and standard deviation of SUV(standard uptake value) and to propose a method to reduce errors in image reading. PET-CT was performed using actual teeth, metal crown, gold crown, titanium, and zirconia dental prosthesis. Compared with general teeth, the SUV value increased with increasing HU value. The SUV value of metal crown, titanium, and zirconia was increased by 37% and the gold crown increased by 45.4%. In addition, image distortions were small in general teeth, metal crown, titanium, and zirconia, but hard curing of the gold crown occurred and image distortion occurred. Therefore, since the metal type of the dental prosthesis affects the SUV value, the NAC(non attenuation correction) PET image of the dental prosthesis can be helpful in the diagnosis of the patient using the gold material.

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.

This report demonstrates the immobilization of uniformly sized gold nanoparticles (AuNPs) on UV cross-linked poly(4-vinylpyridine) (P4VP) polymer thin films and the preparation of micropatterned structures of AuNPs on these films. The polymer thin films were prepared by a spin-coating of P4VP onto a cleaned silicon wafer surface. Upon UV irradiation, these films were then photo cross-linked. Gold nanoparticles were immobilized by immersing the polymer surface in a colloidal solution of gold nanoparticles stabilized by citric acid. The morphology of the films and the immobilization of AuNPs were studied by atomic force microscopy (AFM) and UV-visible spectroscopic techniques. The micropatterned gold structures that were produced on the polymer surface are delineated by combining with the photolithographic method. While untreated and simply spin coated films were physisorbed and unstable that could be easily removed by rinsing with a solvent, the cross-linked and AuNPs immobilized P4VP films were found to be highly stable even after repeated solvent extractions.

The local field distribution around gold nanosphere-gold plane junction has been studied using the finitedifference time-domain (FDTD) electrodynamics calculation procedure. We find that both the in-plane and out-of-plane polarized excitation produce enhanced field strong enough to explain the observed SERS activities of the junctions. Comparison with a simple dipole-image dipole model shows that the enhanced field primarily originates from the multipole-image multipole interaction, which indicates that the detailed fine-structures of the nanoparticles also play a significant role in the SERS activities as well.

Purpose: To monitor the changes of location of prostate gland using DIPS and to examine the adjustment and proton beam therapy depending on the movement of prostate gland in proton beam therapy for prostate gland in which a fiducial gold marker was inserted. Materials and Methods: This study was conducted in ten patients with prostate cancer who received proton beam therapy since April of 2008. To monitor the change of prostate location, three fiducial gold markers were inserted prior to the treatment. To minimize the movement of prostate gland, patients were recommended to urinate prior to the treatment, to intake a certain amount of water and to concomitantly undergo rectal balloon. In these patients, the set-up position was identical to that for a CT-simulation. The PA (posterior-anterior) and lateral images were obtained using both DIPS (digital image positioning system) and a plain radiography, and they were compared between the two imaging modalities. Thus, the changes of the location of fiducial gold marker were assessed based on three coordinates (x, y, z) and then adjusted. This was followed by proton beam therapy. Results: Images which were taken using a plain radiography were compared with those which were taken using DIPS. In ten patients, according to a reference bony marker, the mean changes of the location of fiducial gold marker based on an iso-center were X-axis: $\pm$0.116 cm, Y-axis: $\pm$0.19 cm and Z-axis: $\pm$0.176 cm. These ten patients showed a difference in the changes of location of prostate gland and it ranged between RT: 0.04 cm and RT: 0.24 cm on the X-axis; between Inf: 0.03 cm and Sup: 0.42 cm on the Y-axis; and Post: 0.05 cm and Ant: 0.35 cm on the Z-axis. Conclusion: To minimize the movement of prostate gland, as the pre-treatment prior to the treatment. In all the patients, however, three fiducial gold markers showed a daily variation which were inserted in the prostate gland. Based on the above data, Thus, the requirement of gold marker matching system depending on the daily variation in the proton beam therapy for which more accurate establishment of target was confirmed. It is assumed that an accurate effect of proton beam therapy would be enhanced by adjusting the target-center depending on the location change of prostate gland using DIPS which was used in the current study.

It is very important that analysis of textures in rock, the moving of hydrothermal solution along the structures, epithermal vein textures, mineralization and composition minerals to confirm the hydrothermal ore deposits and ore genesis. The purpose of this study is to confirm the gold mineralization and ore genesis through the moving of hydrothermal solution along the structure lines and epithermal vein textures by using Color-corescanner techniques. The three drilling hole cores of Sunshin Gold Mine in Haenam area in Jeonnam Province were into a digital image data. Digital image data of gold bearing epithermal vein textures were analyzed detaily by Color-corescanner. There are several epithermal vein textures, namely Comb texture, Cavity texture, Bladed texture, Zonal texture, Brecciated texture and Combined texture. Gold mineralization is dominated in vein type textures, but high grade gold are enbedded in brecciated texture. Ore genesis is epithermal gold deposit. This Color-corescanner techniques can cover the missing part of the examine with the naked eye, and can examine closely the situation of ore deposit development and genesis by detail checking the textures in rock, mineralization and so on.

To fabricate uniform and reliable thin gold stripes that provide low-loss optical waveguides, we developed a novel liftoff process placing an additional $SiN_x$ layer under conventional photoresists. By patterning a photoresist and over-etching the $SiN_x$, the photoresist patterns become free-standing structures on a lower-cladding. This leads to uniform metal stripes with good reproducibility and effectively removes parasitic structures on the edge of the metal stripe in the image reversal photolithography process. By applying the newly developed process to polymer-based gold stripe waveguide fabrication, we improved the propagation losses about two times compared with that incurred by the conventional image-reversal process.
