Shahr-e Sukhteh (meaning burnt city in Persian) in Iran is an archeological site dated back to around 3,200-1,800 BC. It is located in Sistan and Baluchistan Province of Iran and known as the junction of Bronze Age trade routes crossing the Iranian plateau. It was appointed as current study area for paleoparasitological investigations. Excavations at this site have revealed various archeological materials since 1967. In the present study, sheep and carnivore coprolites excavated from this site were analyzed by means of rehydration technique using TSP solution for finding helminth eggs. Dicrocoelium dendriticum, Capillaria sp., and Taenia sp. eggs were identified, while some other objects similar to Anoplocephalidae and Toxocara spp. eggs were also retrieved from the samples but their measured parameters did not match those of these species. The present paper illustrates the first paleoparasitological findings of Bronze Age in eastern Iran supporting the economic activities, peopling, and communication as well as the appropriate condition for zoonotic helminthiasis life cycle in Shahr-e Sukhteh archeological site.

In metalcraft, there are two kind of skills, one is forming and the other is decoration. And we could discern these skills as metal casting and metal hammering.. In metal casting, there are sand mould, cire perdus, stone mould and sealed monld; In metal hammering, metal forging, repousse technique and metal sheet making. After make form, craftman can use the decoration skills. There are chasing hammering, line carving, dotted line engraving, hair line engraving, kicking line engraving, ring punched ground, inlay, filigee and granulation skills. In korean traditional copper alloy, the craftman used forming and decoration skills. In Korea, tradionally the clatter use bronze for copper alloy; in case of Japan, they use violet coloring, and in case of Chinese, they like to use bronze used copper alloy. In case of Alloy, korean craftman used bronze traditionally, but recently the copper alloy skill is usually used; in case of Japan shibuichi and shakudo skills are used; and in Chinese copper, brass and cupronikel alloy are used.

The contemporary shoes have been progressively trying a variety of designs using patterns as well as the formative change. However, for making those patterns secure the continuing values as the design having global competitiveness without being a temporal trend, it is required to develop the patterns which reflect the unique identity of Korea. Such development can be realized through the analysis on the traditional patterns of Korea. The patterns are the symbol of collective values. The traditional patterns implicitly express the philosophical thinking of members in a society as having been inherited up to now. Thus, this paper analyzed the gilt bronze shoes in Three Kingdoms Era using the patterns as unique design elements among traditional shoes of Korea. The symbolism of those patterns was expressed as transcendence of time and space, harmony of spirit and materials, and convergence of a region and religion. On the aspect that our ancestors interpreted and overcame the bounds of nature around human beings, pursued the ideal beyond reality and accepted a variety of thoughts, it is considered that the patterns used in gilt bronze shoes expressed anthropocentricism, idealism and inclusivism.

This paper was researched that provenance of the raw material for bronze relics excavated Cheonghaejin using the distribution of lead isotope ratio based on galena ores of South Korea. Also we want to make sure that the trace elements appearing as a by-product can be used as a secondary indicator for provenance research. In the case of the galena map of the East-North Asia (Mabuchi, 1985), data are plotted in China area. Therefore it is estimated that most bronzes were produced with lead ore from China. On the other hand, the same data are plotted in the Okcheon Metamorphic Belt and Yeongnam Massif of the galena map of South Korea (KOPLID, 2012). Also the contents of Ag and Sb are available as indicator due to separate ores from similar zone in lead isotope ratio.

Isotope amount ratios of lead in a bronze sample have been successfully determined using multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS). Matrix separation conditions were tested and optimized using ion exchange chromatography with anion-exchange resin, AG1-X8, and sequential elution of the 0.5 M HBr and 7 M $HNO_3$ to separate lead from very high contents of copper and tin in bronze matrix. Mercury was also removed efficiently in the optimized separation condition. The instrumental isotope fractionation of lead in the MC-ICP-MS measurement was corrected by the external standard sample bracketing method using an external standard, NIST SRM 981 lead common isotope ratio standard followed by correction of procedure blank to obtain reliable isotope ratios of lead. The isotope ratios, $^{206}Pb/^{204}Pb$, $^{207}Pb/^{204}Pb$, $^{208}Pb/^{204}Pb$, and $^{208}Pb/^{206}Pb$, of lead were determined as $18.0802{\pm}0.0114$, $15.5799{\pm}0.0099$, $38.0853{\pm}0.0241$, and $2.1065{\pm}0.0004$, respectively, and the determined isotope ratios showed good agreement with the reference values of an international comparison for the same sample within the stated uncertainties

An ancient Korean bronze dagger excavated from Yongjai-ri, Iksan-kun, presumed to be manufactured in the pre-historical age, was examined by means of chemical analysis, energy dispersive spectrometry, optical and scanning electron microscopy. Also the measurement of lead isotope ratios was carried out in order to predict the site where raw materials were produced. The composition was identified as 75.3% Cu, 17.1% Sn and 6.8% Pb which was a typical composition of Korean bronze dagger. The microstructure was consisted of ${\alpha}$ and (${\alpha}+{\delta}$) eutectoid. The (${\alpha}+{\delta}$) eutectoid can be easily corroded in comparison with ${\alpha}$. The segregation was frequently observed in the interior of the sample. According to the lead isotopes ratios, raw materials have possibility to be from North China.

This paper focuses on the relationship between center and periphery by discussing the circulation of rare resources, such as bronze, stamped hard pottery, and proto-porcelain. The discussion includes two parts: the internal Shang culture region and the region outside of Shang. Within the Shang culture region, all the resources mentioned above were brought from different places to the Panlongcheng site and then transferred to Zhengzhou Shang city. On the other hand, they also produced and consumed the resources in a special way, which indicates a certain degree of independence. Outside the Shang region, bronze products and maybe even raw copper resources were circulated from Zhengzhou Shang city to the Chengyang site, while stamped hard pottery and proto-porcelain were transferred to Zhengzhou through the Panlongcheng site. Resource circulation was bi-directional. Thus, this resource circulation was one of the key factors to building the relationship between center and periphery.

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.

In excavated bronze artifacts, corrosion products of various shapes and colors are observed due to multiple corrosion factors coexisting in the burial environment, and these corrosion products can constitute important data not only in terms of long-term corrosion-related information, but also in connection with preservation of artifacts. As such, scientific analysis is being carried out on the corrosion layer and corrosion products of bronze artifacts, and the corrosion mechanism and the characteristics of corrosion products elucidated, which is essential for interpreting the exposed burial environment and its association with corrosion factors inside the burial environment. In this study, after classifying excavated bronze artifacts according to alloy ratio and fabrication technique, comprehensive analysis of the surface of corrosion artifacts, corrosion layer, and corrosion products was carried out to investigate the corrosion mechanism, formation process of the corrosion layer, and characteristics of corrosion products. The study designated two groups according to alloy ratio and fabrication technique. In Group 1, which involved a Cu-Sn-Pb alloy and had no heat treatment, the surface was rough and external corrosion layers were formed on a part, or both sides, of the inside and the outside, and the surface was observed as being green or blue. α+δ phase selection corrosion was found in the metal and some were found to be concentrated in an empty space with a purity of 95 percent or more after α+δ phase corrosion. The Cu-Sn alloy and heat-treated Group 2 formed a smooth surface with no external corrosion layer, and a dark yellow surface was observed. In addition, no external corrosion layer was observed, unlike Group 1, and α corrosion was found inside the metal. In conclusion, it can be seen that the bronze artifacts excavated from the same site differ in various aspects, including the formation of the corrosion layer, the shape and color of the corrosion products, and the metal ion migration path, depending on the alloy ratio and fabrication technique. They also exhibited different corrosion characteristics in the same material, which means that different forms of corrosion can occur depending on the exposure environment in the burial setting. Therefore, even bronze artifacts excavated from the same site will have different corrosion characteristics depending on alloy ratio, fabrication technique, and exposure environment. The study shows one aspect of corrosion characteristics in specific areas and objects; further study of corrosion mechanisms in accordance with burial conditions will be required through analysis of the corrosive layer and corrosive product characteristics of bronze artifacts from various regions.
