Ancient metal objects with inlaid designs were mainly decorated using the wire inlay technique in which "V"- or "U"-shaped grooves were cut in a metal object and then filled with gold or silver. Previous studies on ancient metal objects featuring wire inlay generally attempted to ascertain the inlay techniques applied by examining photomicroscopes acquired during conservation treatment. However, they had limitations when examining wire inlay technique to the minute details. Wire inlay technique can be better investigated by enlarging X-ray films of relics using stereoscopic microscopy under transmitted light. The core processes of the wire inlay technique involve cutting grooves using a chisel and creating the inlay wires, but researchers hold varying opinions about the two processes. This study analyzed the entirety of the materials able to shed light on the main processes applied in Baekje wire inlay by examining X-ray films of relics through stereoscopic microscopy. This exhaustive research revealed that two types of techniques were used for wire inlay during the Baekje period. One is a plastic process of engraving dotted lines using a chisel and is found mostly in objects from the Cheonan and Gongju areas. The other is a cutting process that incises fine lines and was used mostly in relics from the Osan, Seosan, and Wanju areas. It is likely that the Baekje wire inlay techniques feature regional differences because the respective techniques were used or introduced by different groups of people.

This research is about the reproduction of Baekje's armor-lamellar made for the Hanseong Baekje Museum exhibition. The purpose of the research are as follows. First, to categorize Baekje armor by type based on ancient documents and the excavated relics. Second, to reproduce categorized armor that provide a visual work for use in diverse areas. Baekje armor can be examined through the ancient records and several excavated relics. The results of the research are as follows. First, Baekje armor can be categorized into four types by material: 1) brass 2) iron 3) leather 4) bone. The can also be categorized into three types by finishing a) Hyeongnyubongnyun type (the leather skin interweaves with the lamellar armor method) b) Hyeokpobongnyun type (the method which wraps around the edges of leather skin) c) leather cloth added to clothe type. Second, we reproduced metal armor, iron armor and leather armor using brass, iron and leather (but not bone). Each type of armor were made life-size for exhibition purposes. We used Hyeongnyubongnyun method, Hyeokpobongnyung method and leather cloth; in addition, reproductions were made based on the Yangdang method that connected the front and the back from both sides of the shoulders so it can be open and close at the side part.

In this article the purpose of the study on Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" is to ascertain the era of that publication according to recent investigation and find the properties of that book through comparision with other "Huangjenaegyeongsomun(黃帝內經素問)" published in ancient Korea, Choseon Dynasty. Because we are not yet secure more various Eulhae metal type(乙亥字) books and collaterally printed books, and there would be more unknown Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" in Korea or abroad, so this study focuses on investigation of publish are only based on the record in that book, and comparision with the context of other Korea-published "Huangjenaegyeongsomun(黃帝內經素問)". As a result Eulhae metal type(乙亥字) "Huangjenaegyeongsomun(黃帝內經素問)" was published in Myeongjong era about 1554-1557, was the very original book of exiting Naeeuwon(內醫院) type "Huangjenaegyeongsomun(黃帝內經素問)". This Publication of this book published with Eulhae metal type(乙亥字) "Huangjenaegyeongyeongchu(黃帝內經靈樞)" at the same period explains that at that time Choseon Dynasty lay emphasis on promoting Medicine and teach "Huangjenaegyeong(黃帝內經)".

This study intends to identify manufacturing techniques, including casting and alloy composition, of nine metal Buddha statues excavated from archaeological sites in Bagan, Myanmar. Two Buddha statues from Pyu city state(2^nd to 9^th century) contain Cu-Sn alloy(including <1 wt% Fe), with different relatively high percentages of Sn(16 wt% and 25 wt%) identified from each Buddha statue, and no Pb detected. Five Buddha statues from the Bagan dynasty contain various alloy ratios of Cu-Sn(including <1 wt% Pb), Cu-Sn-Pb, and Cu-Sn-Zn-Pb. All Buddha statues appear to be fabricated by casting, as there is no evidence of other heat treatments. The silver Buddha statue manufactured in the 18^th century includes >1% Cu besides silver with no additional metallic components identified. The bronze Buddha statue manufactured in the Konbaung dynasty(18^th century) is of Cu-Sn-Pb alloy. The Buddha statues of Pyu was alloy of Cu-Sn without Pb including ahigh percentage of The Buddha statues of both the Bagan and Konbaung dynasties are comprised of ternary Cu-Sn-Pb alloys, with a heterogeneous distribution of lead and tin. Some of Buddha statues of the Bagan dynasty have similar alloy ratios as those of Pyu, suggesting that similar manufacturing techniques were used.

Questions of how our Milky Way evolves through the interaction with its environment have been constantly raised. One particularly interesting question is how the metallicity would change as our Milky Way goes through collision with HVCs. Because of the possibility of HVCs providing fuel for star formation in the Galactic disk, we simulate the collision between HVCs and the Galactic disk. More specifically, we trace how the Galactic metallicity changes throughout the process of HVCs colliding with our Milky Way based upon a specific scenario that HVCs are primordial gas left-overs from an ancient galaxy formation. Such mixing between metal-rich gas (disk) and metal-poor HVC can be traced by running numerical simulations with the FLASH code due to its capability of tracking down the abundance change of a specific element such as carbon at each time step of the hydrodynamic evolution. As for now, we give how this mixing depends on model parameters that we choose such as collision speed, initial metallicities, temperature and so on.

The metal-manufacturing method and smelting temperature of ancient metal-production processes have been studied by analyzing the principal elements and microstructures of slag. However, the microstructure of slag varies according to the solidification cooling rate and types and relative amounts of various oxides contained within the smelting materials. Hence, there is a need for accurate analysis methods that allow slag to be distinguished by more than its composition or microstructure. In this study, the microstructures of slag discharged as a result of smelting iron sands collected from Pohang and Gyeongju, as well as the slag excavated from the Ungyo site in Wanju, were analyzed by using metalloscopy, scanning election microscopy-energy dispersine X-ray spectroscopy(SEM-EDS) and wavelength dispersive X-ray fluorenscence(WD-XRF). Furthermore, the microcrystals were accurately characterized by performing Raman micro-spectroscopy, which is a technique that can be used to identify the microcrystals of slags. SEM-EDS analysis of Pohang slag indicated that its white polygonal crystals could be Magnetite; however, Raman micro-spectroscopy revealed that these crystals were actually $ulv{\ddot{o}}spinel$. Raman micro-spectroscopy and SEM-EDS were also used to verify that the coarse white dendritic structures observed in the Gyeongju-slag were $W{\ddot{u}}stites$. Additionally, the Wanju slag was observed to have a glassy matrix, which was confirmed by Raman micro-spectroscopy to be Augite. Thus, we have demonstrated that Raman micro-spectroscopy can accurately identify slag microcrystals, which are otherwise difficult to distinguish as solely based on their chemical composition and crystal morphology. Therefore, we conclude that it has excellent potential as a slag analysis technique.

Modern metal craft is losing our tradition and personality with simple expressive methods and limited techniques without artistry with the purpose of mass production. In order for development of modern metal craft and to succeed our unique culture, there is a need to consider traditional craft techniques that have been delivered since the ancient. Inlay craft requires high concentration and technology, and it is typical traditional metal craft techniques that show contemporary culture and ideas well. the period of the Three States was the time when inlay technique was introduced the first, and it can be seen in Baekje, Gaya and Silla. Furthermore, when inlay craft is applied for modern metal craft, a possibility was found to grant artistic expression and historical value of our unique artistic expression and historical value. For this purpose, it is expected to establish development of modern metal craft and our unique individuality firmly when continuously seeking practical measures that can accept contemporary crafts and expanding opportunities of education to learn traditional techniques.

This study investigates the symbolism and meaning of the bead design, its relationship with the Silla culture, and the conditions of glass bead manufacturing to verify the theory of Silla's production of Silla face-inlaid glass beads with excellent artistry and technology. The research method includes investigating the design analysis, ancient documents, myths, relics, glass, and metal production techniques. Moreover, Hongshan cultural relics and other cases of inlaid glass beads were collected. There are records in the literature that the people of Makhan, Buyeo and Silla of ancient Korea people considered beads as treasures and used them for accessories. It was confirmed that all the design elements of the bead-patterned hair topknot, golden crown, birds, and flower trees were closely related to the myth of Kim Al-ji of Silla, the oviparous tales and the sacred birds and divine beasts of the north. Moreover, the pattern and arrangements were found to be similar in other Silla relics. The origin of beads and face pendants was Hongsan culture, and a stone cast for beads was discovered in Bukpyo of Gojoseon, the lower-level culture of Hajiajeom. In addition, excavating inlaid glass beads from Sik-ri tombs of Korea and a face-inlaid glass bead from Toganmori tombs in Japan confirms the theory of Silla's production. The fact that the Baekje people of ancient Korea had a glass bead manufacturing office in Japan in the fifth centuries suggests that the Silla people also had a manufacturing plant in Java, Indonesia, because this place was a crossroads of Silla's Sea Silk Road and a source of raw materials and labors with a close relationship to Silla. Therefore, the face-inlaid glass bead was indeed self-made by Silla, who possessed the tradition of bead myths and hair topknot, and the high-level skills such as gold crowns and metal inlays.

The purpose of this study is how have the form and theory of the five element theory in the (黃帝內徑) by the investigation of the course of the course of the five element introduced the ancient oriental medicine from ancient oriental philosophy. The following results were obtained. 1. The five elements in (尙書) meaned the uses of water, fire, earth, wood, metal which were important in living. Because these had very important meaning in ancient political and economic society, emphasized to big law(洪範) 2. The five elements in (左傳) and (國語) mean the five uses too, and there are the phases of "five win metal"(火勝金) and "wather win fire"(水勝火), but these only meaned the physical interrelation. 3. In the five circulating factor theory made by Chu Yen(鄒衍) which have the attribute of the five elements, he more reasonably had argued human affairs like that a dynasty become different in step with the circulating five favors. There is the regular annual policy in the (呂氏春秋) which closely connected nature and human living, and attached the various colors, animals, visceras, flavors, sounds, the sexagenary cycle and so on to the five elements. 4. In the (春秋繁露) writed in fore-period of Han(漢) dynasty, the interactions of the five elements are concretely applicated to policy, Dong Jung Soe(童仲舒) had discrived the interactions of the five elements by Dong Lyu Sang Dong theory(同類相動說) and the misfortune theory(災異說), emphasized the sympathy of nature and human. Thought there is many content which are superstitious and contradictory, I concider which that affcted many effects in the formation of five element theory of oriental medicine. In the (淮南子) the order of matters were explained by the five element theory too, as the interrelations of the five elements were explained by the sexagenary ctcle, I assume that the bud of O-Un theory(五運理論). And there was not founded the fullscale intriduction of the five element theory in the Ma Wang Tye(馬王堆) excavated finds, the Mu Yyi medical writings formed the dynasty(武威漢代醫簡) and the documents about Pyun Jak(偏鵲) and Sun U Ie(淳于意). 5. The application of the five element theory in the (Whang Di Nei Qing) (黃帝內徑) is devided into the attachement to the five elements, the interelations of the five elments, and Un Gi theery(運氣論). In the attachment to the five elemeant theory, it made the attachment of the five viseras of (今文尙書) party a standard and attached the sections of a human body, the whole internal organs of sense, the five colors, the five flavors and the five sounds and so on to the five elements. It put to use by means of the apllivation of the interrelation of the five elements in the transferations of the diseases and the relative severeness of a disease in step with change of time and season. Un Gi theory(運氣論) which synthesized by the attachment to the five elements, the inter-relations of the five elements and the climate which observerd from ancient times systematically argued the effects of weather to human. 6. The application of the five elements theory in (黃帝內徑) have the significant what had get rid of irrational factors like that the emotion and action of human could to influense the weather, what had been formes more rational thingking by the obesrvation of human and nature. It is required more reserches about the possibility of the formation of the doctrinal faction bt the geographical effect of the Yon, Je(燕,薺) region, the application of the five element theory in other ancient medical books and the relationship of the five element theory and Yin Yang(陰陽)
