A mural was discovered in the Ssanggyesa temple located in Jindo island, during repair of the Daeungjeon Hall. A study was conducted to determine the binding medium used for preparing the mural. Pyrolysis/GC/MS and IR spectrometry were used to analyze a painting specimen. Direct approach and on-line methylation approach were attempted for the pyrolysis/GC/MS. In IR analysis, the spectra of the specimen were found to be different from those of Asian lacquer, yellow lacquer, animal glue, and acrylic emulsion resin. They were also not identical to the standard IR spectra of drying oils such as linseed oil. Pyrolysis/GC/MS results of the specimen were different from those of Asian lacquer, yellow lacquer, animal glue, and acrylic emulsion resin. In the mean time, palmitic acid, octadecanoic acid, nonanedioic acid, and octadecenoic acid, which are characteristic pyrolysis products of dried drying oil, were detected. In addition, the pyrolysis/GC/MS chromatograms of the specimen and dried drying oil were also very similar. Therefore, it was concluded that the painting was prepared using drying oil as a binding medium.

In this study, the researchers attempted to automate the process of painting the characters on the road surface, which is currently done by manual labor, by using the information and communication technology. Here are the descriptions of how we put in our efforts to achieve such a goal. First, we familiarized ourselves with the current regulations about painting letters or characters on the road, with reference to Road Mark Installation Management Manual of the National Police Agency. Regarding the graphemes, we adopted a new one using connection components, in Gothic print characters which was within the range of acceptance according to the aforementioned manual. We also made it possible for the automated program to recognize the graphemes by means of the feature dots of the isolated dots, end dots, 2-line gathering dots, and gathering dots of 3 lines or more. Regarding the database, we built graphemes database for plotting information, classified the characters by means of the arrangement information of the graphemes and the layers that the graphemes form within the characters, and last but not least, made the character shape information database for character plotting by using such data. We measured the layers and the arrangement information of the graphemes consisting the characters by using the information of: 1) the information of the position of the center of gravity, and 2) the information of the graphemes that was acquired through vertical exploration from the center of gravity in each grapheme. We identified and compared the group to which each character of the database belonged, and recognized the characters through the use of the information gathered using this method. We analyzed the input characters using the aforementioned analysis method and database, and then converted into plotting information. It was shown that the plotting was performed after the correction.

In this study we investigate the problem of reducing color change cost at painting operations in an automobile assembly plant. Changing control logic at conveyor junction points prior to the top coat line has been proposed and analyzed using the discrete event simulation model we developed using AutoMod. We also discussed the project which initiated this research as well as the details of painting operations. Simulation analysis showed that the grouping ratio increases from 1.8 to 2.5 if the proposed control logic change is applied to the plant. Contrary to other approaches such as using dedicated equipment for resequencing, our approach has the merit of less investment cost, no need for additional space consumption. We finally note that the grouping ratio can be further increased if our algorithms is implemented as well as CRS (Color Rescheduling Storage) is installed.

Heungdukwang's(興德王) costume ordinance(834A.D.) is a very important written historical record because it reveals Tongil Shilla's(統-新羅) costume. And among the clothing pieces that appeared in Heungdukwang's(興德王) costume ordinance, from Pyosang(表裳), Naesang(內裳), we know they wore one skirt over another. But skirts appearing in visual records are wort in waist line or breast line, and when they wore skirts in breast line, there were shoulder belts or not. Also among the clothing pieces that appeared in Heungdukwang'a (興德王) costume ordinance, Yo( ) and Ban( ) seems to be connected with skirt. but it is not clear. So this study focuses on the history of wearing skirt in breast line and one skirt over another, shoulder belts of skirt, and relation among yo( ), Ban( ) and skirt. The results are as follows. First, wearing skirt in breast line is already appeared in Ancient Shilla's(新羅) clay figure, and wearing one skirt over another is also appeared in Sunhung tomb's mural painting. so it is not completely under the influence of Tang(唐). Second, the shoulder belts of skirt is for convenience of action, But, at that time, there is no shoulder belts of skirt in Tang(唐). Third, between Yo( ) and Ban( ), If Yo( ) is connected with skirt, it is a shoulder belts of skirt or waist of skirt. And Ban( ) is a ire of skirt.

The purpose of this study is to compare the style of clothing by type of the Goguryeo and Xianbei Tribe based on the examination of the literature centered on the historical relationship between Goguryeo and Xianbei Tribe. The research results are as follows. First, it was found that both the apparels of Goguryeo and Xianbei Tribe had hemp cloth with the V-neckline with the blocked front part and hemp cloth with the open front that is worn by overlapping the straight collars of the upper garment. Both men and women wore the garment of the straight line collar that is worn by folding towards the left or right, or upper garment of the round shaped collar. Women wore an upper garment with short sleeves on top of the upper garment of Korean traditional clothes while men wore pants for the lower garment, and women wore skirt and apron with triangular cloth decoration on top of the skirt. Second, Goguryeo Anak Tomb No. 3 mural painting(year 357) shows that apparel worn by the lady who is the wife of the owner of the tomb is similar to the apparel worn by the lady in the lacquer painting for folding screen of the Sima Jinlong Tomb ancient painting on the woman of chaste reputation in terms of the form and structure.

Recently, various attempts are being done to apply off-line programming system to field of paint robot. But most commercial simulation softwares have problems that are slow simulation speed and not support various painting paramenters on simulation. This paper proposes enhanced paint simulation method for off-line programming system. For these, this method used the mathematical model of flux field from a previous research. The flux field has the flux distribution function, which reflects on the feature of paint spray. A previous research derived this flux distribution function for an integral function and calculated paint thickness function for an integral function. But if flux distribution function is defined as an integral function, it is inadequate to use for real-time simulation because a number of calculation is needed for estimation of paint thickness distribution. Therefore, we defined the flux distribution function by numerical method for reducing a mount of calculation for estimation of paint thickness. We derived the equation of paint thickness function analytically for reducing a mount of calculation from the paint distribution function defined by numerical method. In order to prove proposed paint simulation method this paper compares the simulated and measured thickness. From this comparison this paper show that paint thickness distribution is predicted precisely by proposed spray paint simulation process.

The dragon of the East was an object of worship and an authority to make rain, unlike the West. The dragon image, one of the positively accepted Chinese motifs with the blue-and-white porcelain of the Ming dynasty by the Ottoman Empire in the 16th century, was combined with gigantic saw-edged leaves to create a genre in Saz style. By combining Eastern dragons with plant motifs instead of clouds, dragons were no longer accepted as authority and nobility but as symbols of life and longevity. Unlike Iran and other countries, the image of dragons in Turkish miniature paintings has evolved into a unique style using Turkish calligraphy. The stylistic feature is that a thick black line that gives the impression of calligraphy forms the dragon's back or a huge saz leaf stalk and forms the axis of the screen. Most of the work was black ink drawing, not painting, and partly lightly painted. In the development stage, the dragon appears as a protagonist on the screen of the early works, but the dragon retreats to the latter half and the saz leaves play a leading role on the screen. A common feature in all paintings, whether early or late, is that they have a militant character and create tension on the screen. From the viewpoint of comparative culture, Turkish dragon miniature drawings of the 16thcentury Ottoman period and the Joseon dynasty are somewhat similar in that they are based on calligraphic character and desire for longevity and loyalty, and are drawn according to certain iconic principles.

In this paper, we have designed an optical measurement system for authenticity of paintings. Using a simple and compact optical measurement system, the surface characteristics of paintings could be measured, and we obtained information about paintings. First, the paintings that were painted in various colors could give characteristic information on the color of paintings. Second, tomographic information about the surface of a painting could be obtained, using a line laser. To assess the reliability of the optical measurement system, forgeries looking like the originals were created, and we could distinguish the originals from the forgeries through experiment. Thus, we could obtain data about the paintings and create a numerical database.
