This study focused on the Gaya mural tomb located in Goa-ri, Goryeong-gun, North Gyeongsang Province, Republic of Korea. Environmental factors such as ambient temperature, relative humidity and surface temperature, and microbial distribution on mural tombs were monitored for one year to gather data on the conservation environment of the mural tombs. The average internal temperature difference with reference to the ambient outer temperature was observed to be $11.7^{\circ}C$ for the monitoring period and the internal temperature of the tomb was found to change periodically every one or two months in response to the outer temperature. The highest temperature was observed in September and the lowest in March. The relative humidity in the mural tomb remained constant at 100%. Between December and April, condensation occurred on the ceiling of the main room of the tomb, where the murals are located. On the ceiling of the aisle, the condensation occurred throughout the year. The inside and surface wall were isolated from microorganisms, which could grow when a suitable growth environment suitable is established. Based on microbial growth temperature conditions, risk periods of microbial hazards were established, where in the period from August to October was identified as the most dangerous.

The conservation of damaged object should be restored by the similar material with the original and they have to reversibility as possible as. The characteristics of Buddhist mural paintings composed of clay are with soft material. So far, there have been a number of researches done on filling material that reinforces cracks and exfoliation of mural painting. Based on the application of traditional materials, it was found that they are appropriate to various applications. However, only based on those research results, there are some constraints to the application in the field. In addition, there has been only a few researches done on physical characteristics of filling materials. A major issue is that there is not any standard established on various mixing ratio, which is required for treatment of mural painting. This study was carried out to understand the physical characteristics of filling materials on clay mural painting. The 1st test was conducted to analyze test specimen in twelve different conditions by varying soil mixing ratio and organic medium. The 2nd test was conducted to manufacture filling materials appropriate to the mural painting, based on the result of stable condition from the 1st test, and which was applied to treatment in field.

For the conservation treatment of the Central Asia mural painting which is to be exhibited in the new museum in Yongsan, we analyzed the pigments used in this mural painting and examined to identify the species of the straw in the wall. We also analyzed the species of the wood of the wooden protective frame and the material of the paper in it, in order to review the material and technique of the conservation treatment performed before the mural painting had been brought to the National Museum of Korea in 1916. The results were as follows: the black pigments of Bon4075 and Bon4078 is carbon(C); the white pigment on the background is gypsum[Ca(SO)₄(H₂O)₂]; the red pigment is lead oxide(Pb₃O₄) and hematite(Fe₂O₃) etc. The straw, which had been mixed into the wall to prevent the wall from cracking, was proved to be either wheat straw or oats straw. The wooden protective frame, which protects the mural painting now, was proved to be made of Salix, Populus, Cryptomeria japonica and pine. The paper discovered in the frame was proved to be made of the bark of a mulberry.

This study suggests a board fence design with a convergence-style mural. The basic structure contains pictorial factors with mural paintings on the fence. It is also equipped with electricity facilities inside the fence itself, so it has not only the unique function of the fence but also the complexity and expandability in order to be used as a garden lighting and security alarm system. All the components meet the standard so they can be manufactured in a factory. Through this design proposal, this study tries to suggest a fence which encourages personal or social communication one another as well as the basic function of the fence. As a result, the fence realizes a broad convergence function of its usefulness for social functioning such as the crime prevention as well as an esthetic function.

The culture of the play of Korean ancient times is well described in the mural painting of Goguryeo. The example is people appearing in the play painting of performance, dance, hunting, and acrobatics out of 20 mural painting of genre. Their costume is broadly classified into performance, dance, hunting, and acrobatic costume and can be subdivided according to the types of costume. First, the head gear of play costume reflected the formality and social conditions of play. In the performance and hunting costume, all performers wore gwanmo(official hats), which seemed to make it a rule to wear gwanmo. Gwanmo was borrowed intactly from Goguryeo without any changes or decorations, which showed that the status symbolism of head gear was applied intactly to play costume. Second, the play costume of Goguryeo enhanced efficiency by blending daily costume with elements and decorations needed for play performance. Specifically the change of length was prominent: the short sleeves of jeogori(traditional blouse), the long sleeves of dance costume, and fastening below the knee or putting into the long shoes to shorten the length of baji(traditional pants). Finally, as it is well known that there was some differences in the expression modes of daily clothes in Goguryeo between Tonggu and Pyeongyang. Similarly, play costume tried to change costume according to the subject of play but maintained the locality and peculiarity of Goguryeo costume. Although performance costume showed many local differences, it also had similarity and peculiarity. In dance costume, long sleeves and patterns which frequently appeared in the Tonggu area reappeared in the Pyeongyang.

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 the past, PVAc [poly(vinyl acetate)] was used as a fixative for the conservation of the murals in the murals of the Payathonzu temple located in Bagan, Myanmar. In this study, attention was paid to gel cleaning as a method for stably removing such PVAc fixatives. Based on the recent research trend related to the cleaning of murals in Bagan ruins, 3 types of gelling agents (Nevek^®, Laponite^®RD, Carbopol^®980) and 2 types of organic solvents (Acetone, Dimethyl carbonate) were selected. Six types of gel cleaners were prepared by mixing gelling agents and organic solvents, and the properties and fixative removability of these cleaners were compared. As a result of confirming the properties of the prepared gel cleaners, the pH of the cleaners was all in the weak acidic to weakly alkaline range, which was a stable condition for mural application. Also, there was no difference in the viscosity of the cleaners depending on the type of solvent, but there was a difference depending on the type of gelling agent used. Regarding the weight loss ratio of PVAc, which is an indicator of removability, the exposure conditions of the gel cleaners, the boiling point of the solvent used, and the viscosity of the gelling agent acted as factors affecting. As a result of comparing the removability of gel cleaners, it was confirmed that the solvent's fixative solubility, the volatility of the solvent itself, and the solvent release control properties of the gelling agent had a great effect on the removability of the gel cleaners. In Part 2, the stability and the running applicability of the gel cleaners will be investigated by making mockup samples reflecting the properties of the materials and techniques used to produce the mural paintings in the Payathonzu Temple.
