Yatsushiro Shrine on the island of Kamishima located in Ise Bay, Japan, contains many cultural artifacts with ancient mirrors in significant numbers. Also included among the artifacts are horse gags and reins that are clearly of the same lineage as the horse harnesses from the unified Shilla era and Goryeo era in Korean history. Type classification and position establishment were carried out on the horse reins kept in the Yatsushiro shrine, including items such as those mentioned previously. Type A horse harness can be classified into 3 types. Based on this classification scheme, the harness type in the Yatsushiro shrine was found to belong to the most recent period. The blacksmith workshop that made the harness was producing iron wares and bronze wares, and it possessed metal forging and metal casting technologies. Note, however, that it was primarily a workshop where iron wares were made. The parts that were visible from the outside when the harness was attached were made from composite bronze, and the reins and bridle linkage were made from iron. Such integration of bronze ware production techniques and iron ware production techniques was an attempt at enhancing the practicality and embellishments on the harness.

This study makes clear Huang Yuan-Yu(黃元御)'s medical thoughts Yi-philosophically. Yi-philosophy(易學) since ancient times is occupied by fundamental problems of various fields of Oriental Science. Confusian Medicine Reseachers of Zhang Jie-Bin(張介賓), Zhang Nan(章楠), Zhu Zhen-Heng(朱震亨) was seriously affected by Yi-philosophy(易學) and Confucianism(儒學). But I don't think that the majority of their medicine theories are occupied by Yi-philosophy(易學) and Confucianism(儒學). But Huang Yuan-Yu(黃元御) studied medicine thoughts on the basis of Tu Shu Yi(圖書易) in almost whole medicine theories and clinical contents. Therefore this study researched medical thinkings of Huang Yuan-Yu(黃元御) on Yi-philosophical medical viewpoint Tu Shu Yi(圖書易)-scientifically. Especially in this paper the author examined a characteristic point in medical thoughts of Huang Yuan-Yu(黃元御), the difference of existing medicine on Nei-Jing(內經) and Yi-medicine of Huang Yuan-Yu(黃元御), a commonness of medicine principles of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬)), medicine theories of Huang Yuan-Yu(黃元御) on Tu Shu Yi(圖書易) and a background of Yi-philosophical medical standpoint. The results was summarized as follows; First, Huang Yuan-Yu(黃元御)'s standpoint on five phase is that the relation of earth and wood fire metal water is form and use(體用). Huang Yuan-Yu(黃元御) insists that the earth represents existence itself and wood fire metal water is concepts that represents actual states. Second, the concept of Four-Constitution of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬) is same. Third, Huang Yuan-Yu(黃元御) doesn't have a standpoint of five-phase on Nei-Ching Medicine, but a standpoint of five-phase on Yi-philosophy. Fourth, water, fire, metal, wood is Four-Constitution that middle qi transformed. Fifth, the middle qi is yang-earth and yin-earth of the spleen and stomach, the physiological function of four viscera is maintained by the movement of ascending and descending of yin and yang earth. Sixth, The middle qi is main role of Four-Constitution. Exchanging of water and fire and the movement of ascending and descending of metal and wood depends on the earth. Seventh, generally medicine researchers speak that human mind is a main role of psycho-function of heart, but Huang Yuan-Yu has the standpoint of spleen-stomach oriented seven emotions not human-mind oriented viewpoint. It represents that a existing thinking of heart-earth center is changed to medical viewpoint of spleen-earth center. Eighth, There is enough ground for controversy on where is the middle point of human in five viscera. Is that spleen or heart? Huang Yuan-Yu(黃元御) insists that the spleen and stomach is middle point, but the standpoint in Four-Constitution medicine of Li Ji-Ma(李濟馬) is that middle point is heart.
This study analyzed 19 samples of harness fittings and pendants, which were excavated in Tomb No. 15 in Songhyeon-dong, Changnyeong. Harness fittings and pendants are used for ostentation, rather than practicality, and were excavated from ancient tombs in Gaya culture. So, they are considered artifacts that compare the production techniques and raw materials. This study aimed to examine the production techniques and provenience studies of Bihwa Gaya, which is estimated to be from the 5th to 6th centuries. According to the research, harness fittings were made of pure copper and were gilded with Au·Ag alloys on their surfaces. Hg was detected together and plated with a mercury amalgam method. As a result of the pendant (fish scales-pattern, oval and fish-tail shape), analysis showed that Fe in the background metal, Cu in the middle layer, and Au and Ag on the surface were the main components. The method of adhesion between Cu and Au·Ag gilded layers are plated by a mercury amalgamation method. So, it was identified by the gilt-iron·gold·bronze technique. Since the pendant (heart shaped) is found to be the main component of Fe in the background metal and Ag in the surface layer, the metal was made gilt-iron·silver technique. The background metal and gilding were additionally fixed using a rivet. The raw materials of 3 harnesses excavated from Changnyeong are plotted in zone 2 in the southern Korean Peninsula. And 16 harnesses were plotted in Chinese copper ore by Mabuchi Hishao in the Chinese Peninsula.
The structure such as building and cultural properties was composed of various materials like wood, metal and stone that have been utilized and exposed to air, wind and rain far a long time. However, because of their special characteristics as structure, collecting of samples that may involve their destruction cannot be permitted, ever for material analysis. Therefore, h order to study the Influence of atmospheric pollution on structure, atmospheric corrosion tests were achieved by making use of materials(bronze. ancient copper, copper, steel and marble) in field exposure tests. Atmospheric exposure sites are selected from places which are characterized by urban, rural, Industrial and marine enoronments In Northeast Asia. According to the results of atmospheric corrosion tests: The corrosion rates of Industrial states In china were more serious than other sampling sites. In the correlation of meteorological factors. wet hours was defiled as Intogeacted hours under that atmospheric temperature is above $0^{\circ}C$ and relative humidity in above 80% that has a great influence on corrosion tests of materials in case of a short time. The relative humidity was above about 75% that resulted in great increase of corrosion rates. In the esimation of corrosion rates between materials, corrosion rates of steel was about thirty times and decuple larger than that of other materials excluding marble in unshelterd exposure and In sheltered exposure.
Radionuclide X-ray fluorescence analysis is a method, which has many advantages for analysing various historic artefacts, as it is relatively cheap, sensitive and non-destructive, and it allows measurements in-situ. However, this analysis has also certain limitations especially concerning sensitivity to chemical elements only, irrespective of the compounds or chemical forms in which these elements have been bonded. In addition, light elements emitting very soft X-rays cannot be measured, and in order to detect a wide range of elements, it is necessary to carry out repeated measurements with different radiation sources. Despite these limitations, valuable information can be obtained about the composition of historic materials and data about the origin and age of these artefacts can be derived. Analyses of wall paintings, ancient metal sculptures or other objects of art provide the basis for historic considerations documented in our results for some objects belonging to the Czech cultural heritage. The results are promising. Thus it is expected that our laboratory will expand its work into more fields of the fine and applied arts.
The Yo-Dae(belt) was made of cloths and leather orginally. Then, it was decorated with metal decoration to become more developed luxury one. The Kwa-Dae of the Three Kingdom period is called as final shape among those ancient mode. Dae-Gu(The origin of belt buckle) was the metallic decoration of the leather belt that the northern nomadic tribe used to wear it. It was considered that the Dae-Gu was more decorated and changed to Kwa-Dae with Yo-Pae. The first stage Dae-Gu didn't have the hook, but a short hook only could move the belt itself was created, and then a movable short hook(China-Jin period Kwa-Dae, etc) to be inside of belt was showed, after that an axis was necessary when it became to long one, It was completed as a belt buckle. The stick shape hook was main stream in China an dthe other northern countries. Meanwhile, Korea has mostly "T" shape hook, and it shows that we developed our own unique style. Classifying the type of the belt plague, there are five types due to the scarved shapes on the Kwa-Dae and the changes. Mainly based on the excavated tomb articles of the three kingdoms and referred to Chinese and Japanese ones. It showed that the belt plague was lightly influenced by the times and area, but was slowly changed and developed to different types through those each ages generally.

Soybean composition, which is different from those of other beans and grains, gives from 35 to 40 percent protein, 15 to 20 percent oil, and 20 to 25 percent sugar. Soybean has been extensively used as the raw material for traditional foods such as bean curd, soy sauce, soy paste and so on, since ancient times in Korea. Ultracentrifugal components of the soybean proteins represent four major peaks with sedimentation constants of about 2, 7, 11 and 15S. The two major reserve protein of soybean, 7S and 11S globulins, have been isolated and characterized by many works. The curd made with microbial enzyme exhibited minuter structure than those of the metal ion-and acid-treatment. Thus, the curd obtained by enzymatic operation serves as a material for further development of food items, and the procedure may by widely applicable in food processing.
Electrochemical Impedance Spectroscopy (EIS) was used to predict corrosion behaviour of metallic Cultural Heritage assets in two monitoring campaigns: 1) an iron bar chain exposed indoor from over 500 years in the Notre Dame Cathedral in Amiens (France); and 2) a large weathering steel sculpture exposed outdoor from tens of years in Ferrara (Italy). The EIS portable instrument employed was battery operated. In situ EIS measurements on the iron chain could be used to investigate the phenomena involved in the electrochemical interfaces among various corrosion products and assess and predict their corrosion behaviour in different areas of the Cathedral. Meanwhile, the sculpture of weathering steel, like most outdoor artefacts, showed rust layers of different chemical composition and colour depending on the orientation of metal plates. The EIS monitoring campaign was carried out on different areas of the artefact surface, allowing assessment of their protective effectiveness. Results of EIS measurements evidenced how employing a simple test that could be performed in situ without damaging the artefacts surface is possible to quickly gain knowledge of the conservation state of an artefact and highlight potential danger conditions.
We have tried the experimental research of lost-wax casting to reconstruct Gilt-Bronze Pensive Bodhisattva; preliminary and reconstruction experiment based on ancient texts. Main object to reconstruct is Korean National Treasure No.83, Gilt-Bronze Pensive Bodhisattva (Maitreya), then we measure alloy ratio and casting method based on the scientific analysis. Other impurities were removed from the base metal components(copper : tin : lead) and their ratio was set to 95.5 : 6.5 : 3 where the ratios for tin and lead were increased by 2.5% each. The piece-mold casting method was used, and piece-mold casting experiments were carried out twice in this study but supplementary research on piece-mold casting was necessary. The microstructure was confirmed to be typical cast microstructure and the component analysis result was similar to that of the prior study. Analysis of the chemical composition is confirmed to copper, tin, lead, and zinc, and the chemical composition of the matrix was 87.8%Cu-7.5%Sn-2.7%Pb-2.1%Zn, and similar to previous experimental research. Also resulted in the detection of small impurity in Zn. Analysis of the mould revealed that the mould was fabricated by adding quartz and organic matter for structural stability, fire resistance, and air permeability. We expect that our research will contribute to provide base data for advanced researches in future.
Ancient Iranians highly esteemed the horse and horse tacks, one of which is the jul (saddlecloth). It is a felt, sheepskin, or woven pad placed between the horse's back and saddle. The aim of this paper is to identify and categorize jul designs in the Sāsānian period. The research questions are about the variety of jul designs and how to categorize them. This is fundamental research and the method is descriptive and analytical. Neither a jul nor a saddle-cover remains from the Sāsānian period, therefore the statistical population includes all available items, such as metal and stone items and parget and plasterworks, in which juls are recognizable. Due to the scarcity of such items, all the available samples were studied; so the sampling method is a total enumeration. This is documentary research by means of note-taking and using reliable websites; the data has been analyzed qualitatively. The results show that jul designs were not diverse in the Sāsānian period. All-over designs were dominant. In terms of pattern types, these designs are classified into five groups, each of which has its own formal and aesthetic characteristics: all-over design with a four-petal flower pattern, allover design with a checkered pattern, all-over design with a spotted pattern, allover design with a tiger stripe pattern, and all-over design with a zigzag pattern.
