Surficial sediments from the northern coastal area of Jeju Island, southeastern Yellow Sea (South Sea of Korea) were analyzed for grain-size texture, some geochemical characteristics and clay mineralogy in order to assess their provenance. Rare-earth element compositions and some geochemical discrimination diagrams, especially of Ti/Al, Nb/Al and Rb/Al ratios, were revealed to be useful indices for identifying the origin of sediments. These indices, together with clay mineral compositions, suggest that the coarse-grained sediments originate from the volcanic rocks of Jeju Island, whereas the fine-grained sediments are derived from Chinese rivers, especially the Changjiang River. The oceanic circulation pattern and the physical-chemical properties of seawater in the Yellow and East China seal support the possibility that the fine-pained Changjiang (Yangtze River) sediments can reach the coastal area of Jeju Island (southeastern Yellow Sea).

Deer antler has been widely prescribed in Chinese and Korean pharmacology. Although there have been several reports concerning the effects of deer antler, such as anti-aging action, anti-inflammatory activity, antifungal action and regulatory activity of the level of glucose, the effect on bone has not determined yet. The purpose of this study was to examine the effect of deer antler on osteoblast differentiation. Hexane extract(CN-H) and chloroform extract(CN-C) were acquired from deer antler(Cervus nippon) and MC3T3-E1 pre-osteoblasts were cultured in the presence or absence of each extract. Osteoblast differentiation was estimated with the formation of mineralized nodules and the mRNA expression of alkaline phosphatase(ALP), osteocalcin(OC) and bone sialoprotein(BSP) which are markers of osteoblast differentiation. Non-treated group did not show mineralized nodule. CN-C or CN-H-treated group showed minerlaized nodules in 16 days. In northern blot analysis, CN-C or CN-H-treated group showed the elevated expression of ALP, BSP and OC in 16 days. These results suggest the possibility to develop deer antler as a bone regenerative agent in periodontal therapy by showing the stimulating activity of deer antler on differentiation of osteoblast.

The corridors to the north and south of the $Takl{\bar{a}}m{\bar{a}}k{\bar{a}}n$ (塔克拉瑪干 Ta-ke-la-ma-gan) Desert are the most important regions for cultural confluence on the Silk Road, where caravans made it to the Chinese capital or the Korean Peninsula by the northern road, through the city of Turfan, or the southern path of Khutan. Being an important part of the Silk Road in the course of history, this region was heavily influenced by the cultures of various nations and ethnic communities whose merchants utilized the road to advance their business. The region's language, writing system and literary structure were also affected, so much so that in the course of its tumultuous history, many words, phrases and terms belonging to neighboring cultures found their way into the region, leaving their mark on its linguistic structure. Of the cultural exchanges that took place between the peoples of the region, conspicuous traces can be seen in the architecture, music, literature, texts, and inscriptions. Located in the Turfan region, the minaret of Su Gong (蘇公 Su Gong ) is host to an inscription which bears many signs of such exchanges. As so far no independent research has been conducted to identify the cultural, literary and structural features conveyed in this inscription, the present paper is an attempt to study the inscription in terms of the script, language and syntax in order to unravel the effects of cultures prevalent on the Silk Road on this particular inscription. This study mainly aims to investigate the linguistic structure of the inscription and the impact of the Persian language on Silk Road culture. In fact, we approach the inscription as a symbol of cultural exchange on the Silk Road and will focus on the tradition of Persian inscription-making which affected the Turfan inscription.

Actin is a ubiquitous and highly conserved protein found in eukaryotic organisms. In this study, we describe the cDNA cloning and mRNA expression of an actin gene from the mulberry longicorn beetle, Apriona germari. The A. germari actin cDNA is 1524 bp containing a complete 1128 bp open reading frame that encodes a polypeptide of 376 amino acid residues with a predicted molecular weight of about 41.5 kDa. The deduced amino acid sequence of the A.germari actin cDNA showed 99% protein sequence identity to Homalodisca coagulata actin, differing at only two amino acid positions, and 92-98% protein sequence identity to known insect species actins. The predicted three-dimensional structure of A. germari actin revealed the four residue hydrophobic pulg loop characteristic of the actin family. Northern blot analysis showed that A. germari actin is highly expressed in epidermis and muscle, and less strongly in midgut, but not in the fat body of A. germari larva.

This paper is an attempt to look up the life of Guanyu who was a sainted warrior of Shu Han(蜀漢) and later, was revered as God, especially focusing on the Political perspective of Chinese Dynasty. People represented Guanyu as the general during the Wei Jin Southern and Northern Dynasties(魏晉南北朝), however, throughout the Su-Dang Dynasty(隋唐), Guanyu was Honored in the Wuchengwangmiao(武成王廟) then, was promoted from Hou(侯) to Gong(公), Gong(公) to King(王) in the Song-Yuan Dynasty(宋元). In the Ming-Qing Dynasty(明 淸) when the deification of Guanyu was proceeded most positively, he became a Di(帝) over a King and was endowed with the power over the Three Worlds(三界). He had an influence on nobility as well as the people in Folkbelief over Moral Spirits, and consequently rose through the ranks to become the spiritual guardian. The rulers gave him various names(封號) celebrating the life and work of Guanyu, In fact, they showed interests in the Belief of Guanyu as they attempted to establish an ideological base for the solution of the national disaster and maintenance of feudal system which came to the fore along with the reinforcement for emperor's power.

The province of the People's Republic of China, the Xinjiang Uygur Autonomous Region has historically been known under various names - Eastern Turkestan, Chinese Turkestan, Kashgaria, etc. In the early 19^th century this region was one of the least explored in Western scholarship and for the influence over which the so-called 'Great Game', geopolitical rivalry between Great Britain and the Russian Empire, gradually unfolded. This rivalry was one of the significant factors stimulating increased interest in an in-depth and comprehensive study of the geography, nature, and population of Kashgaria. Accordingly, in the second half of the 19^th to early 20^th centuries, several expeditions were organized that pursued serious academic goals alongside military, diplomatic, and commercial purposes. One of these expeditions, organized by the Imperial Russian Geographical Society, was the so-called 'Tibetan expedition' led by a talented scientist and military figure M.V. Pevtsov in 1889-90. The expedition followed the routes of Eastern Turkestan, the northern outskirts of the Tibetan Plateau, and Dzungaria studying this vast region's geography, topography, nature, climate, and population. The results of this investigation were presented by M.V. Pevtsov in a detailed and comprehensive report published in St. Petersburg in 1895. An important part of this narrative is the so-called "Ethnographic Essay of Kashgaria," which reflects the author's observations and thoughts on this region's ethnic composition, religious beliefs, language, customs, and rituals. This article offers insights and analysis of the content of Pevtsov's report, which provides valuable information about the daily life of the population of Kashgaria at the end of the 19^th century to an English-speaking audience.

In this study, we investigated the time signal devices of Deungnu (circa 1270) and Gungnu (1354), the water clocks produced during the Yuan Dynasty (1271-1368). These clocks influenced Heumgyeonggaknu (1438) of the Joseon Dynasty (1392-1910), exemplifying the automatic water clocks of the Yuan Dynasty. Deungnu, Gungnu, and Heumgyeonggaknu can be considered as automatic mechanical clocks capable of performances. The Jega-Yeoksang-Jip (Collection of Calendrical and Astronomical Theories of Various Chinese Masters) contains records of Deungnu extracted from the History of the Yuan Dynasty. We interpreted these records and analyzed reproduction models and technical data previously produced in China. The time signal device of Deungnu featured a four-story structure, with the top floor displaying the four divine constellations, the third floor showcasing models of these divinities, the second floor holding 12-h jacks and a 100-Mark ring, and the first floor with four musicians and a 100-Mark Time-Signal Puppet providing a variety of visual attractions. We developed a 3D model of Deungnu, proposing two possible mechanical devices to ensure that the Time-Signal Puppet simultaneously pointed to the 100-Mark graduations in the east, west, south, and north windows: one model reduced the rotation ratio of the 100-Mark ring to 1/4, whereas the other model maintained the rotation ratio using four separate 100-Mark rings. The power system of Deungnu was influenced by Suunuisangdae (the water-driven astronomical clock tower) of the Northern Song Dynasty (960-1127); this method was also applied to Heumgyeonggaknu in the Joseon Dynasty. In conclusion, these automatic water clocks of East Asia from the 13th to 15th centuries symbolized creativity and excellence, representing scientific devices that were the epitome of clock-making technology in their times.

The cDNA cloning and developmental profiles of the mRNA for A. pernyi arylphorin was determined. The complete A. pernyi arylphorin cDNA sequence comprised 2,234 bp (without the poly $A^+$ tail), including an open reading frame of 2,112 bp beginning with a methionine ATG at bp34. The A. pernyi arylphorin contained 704 amino acids which are highly enriched in aromatic amino acids, phenylalanine and tyrosine. The calculated molecular mass of the A. pernyi arylphorin from the ORF was 83,439 Da. The deduced amino acid sequence of A. pernyi arylphorin showed 78, 71, 62 and 64% identity with those of H. cecropia, M. sexta $\alpha$ subunit, M. sexta $\beta$ subunit and B. mori storage protein. In Northern blot analysis, the A. pernyi arylphorin mRNA only in the fat body of the 5th instar larvae was responsible for gene expression of the protein, and the synthetic activity of the mRNA was detected strongly in the early larvae, but not in the middle or late-stage larvae. In addition, a very weak signal in mRNA activity was detected in pupal stages, but this was considered to be inactive mRNA after reviewing the results of the labeling experiment of this protein.

The purpose of this study is to grasp the commencement date of Korean-type bronze dagger through the chronology of Chinese data. It focuses on the fact that the same section polishing technique appears both in Korean type bronze dagger and Dongzhou type bronze dagger. Dongzhou type bronze dagger in Anqiu Shandong, in which A1 type section polishing technique is observed, was said to have been collected remains in 1958, but the clear excavation cannot be identified. Therefore, this study presents Tomb No.1 Zuojiawa Jinan, Dongzhou type bronze dagger, and associated products. As associated products, bronze weapon and bronze ware were excavated, whose periods are estimated to be in the Spring and Autumn period, the transition period of Warring States, and the former part of the China's Warring States. Accordingly, the Korean bronze dagger, excavated in the remains of the Han Peninsula appears to have run parallel with the Dongzhou type bronze dagger of the A1 type section polishing technique, excavated in China for a fixed period. In addition, the chronology of Tomb No. 61MI grave in Wanrongmiaoqian, Shanxi is estimated to range from the former part to the middle part of the China's Warring States, which is identified to be connected to the A1 type section polishing technique. Examining the data of the relative date, we can find out that the Commencement Period of the Korean type bronze dagger Culture is seen to be the transition period and the former part of the China's Warring States, which is estimated to be the 5th and 4th centuries BC. This chronology is followed by Tomb No.6512 Zhengjiawazi Shenyang, recorded as the 6th century B.C. which reveals that Liaoning type bronze dagger culture and Korean-typed Bronze Dagger Culture are naturally connected. Furthermore, the A1 type section polishing technique was distributed in the southwestern area of the Korean peninsula and Shandong, China, while the A2 type section polishing technique was distributed in the southern area of the Korean peninsula, Shanxi-Province in China, and Northern Kyushu region in Japan. Seen from the weapon-shaped bronze ware of the section polishing technique, Shanxi area(Central Plains area), China. the southwestern area of the Korean peninsula (northwest area), and Northern Kyushu region in Japan are set up as one traffic road(spreading route). This demonstrates that the section polishing technique emerged around the Han Peninsular, spreading the technique regionally.
