Pax Sinica is a historiographical term, modeled after the original phrase Pax Romana. It refers, in Latin, to a Chinese-provided peace which in turn is used to describe an era of peace in East Asia sustained by Chinese hegemony. In historical terms, both the Pax Sinica of the Eastern hemisphere through Han China and the Pax Romana of the Western hemisphere through Rome signified a trans-regional order based on rules and regulations. This orderly world of the Pax Sinica generated a number of positive results such as the intensification of travel, ever-expanding trade relations, an increase in the overall living standards of the populace, the proliferation of cities, and a demographic upsurge in Eurasia along the ancient Silk Road. During this period, China was the dominant civilization not only in the Eastern hemisphere but also in the Middle hemisphere due to its political, economic, military and cultural influence. This paper aims to reintroduce this historiographical term to elucidate the recent Chinese initiatives in Eurasia along the Silk Road to facilitate the integration and connectivity of the continent.

The purpose of this paper was to take an in-depth look at early American English around the $17^{th}$ and $18^{th}$ century when immigrants from different European countries started to move into the New World. The paper attempted to describe early American English in relation to the process of immigration and settlement from a historical perspective. With a focus on major features of early American English such as uniformity, archaism and richness of lexicon, the paper tried to answer the questions such as how settlement influenced the formation and distribution of regional dialects across the continent, why immigrants tended to show a preference for a uniform way of speaking rather than choosing a variety of regional dialects for communication, and what role foreign languages played in the development of early American English. The overall findings based on the answers to these questions showed how American English went through a variety of processes and changes at the early stages of its development to become a national language later. The paper concluded with some remarks about the implications of the findings for EFL learning and the direction of future research on early American English.

The purpose of this study is to research the ideologies of African-American hair-styles according to cultural phenomena. This is a qualitative research using the books and theses about society, culture, hair and beauty, and materials of internet. The results are; Firstly, African-Americans are citizens or residents of the United States who have origins in any of the black populations of Africa. About 75 percent of the dark-skinned people on this continent have hair labeled "kinky". Secondly, African hair-styles expressed Supernaturalism and Traditionalism in the formative period of African culture. African-American hair-styles reflected Colonialism in the period of slaves. African-American citizen's hair-styles showed Nationalism after 1960s' Black Pride Movement in the period of settlement in America, and expressed De-territorialism since the boom of 1970s' Reggae. Today, the wearing of dreadlocks, cornrows, and afros has transcended racial and religious barriers. No longer necessarily reflections of ancient traditions and cultural identification, they are just as often fashion items.

The long-term variability of sea surface temperature in the East China Sea was reviewed based mainly on published literatures. Though the quantitative results are not the same, it is generally shown that sea surface temperature is increasing especially in recent years with the rate of increase about $0.03^{\circ}C$/year. Other meaningful results presented in the literatures is that the difference of water properties between layers upper and lower than the thermocline in summer shows an increasing trend both in temperature and salinity, suggesting that the stratification has been intensified. As a mechanism by which to evaluate the wintertime warming trend in the region, the weakening of wind strength, which is related to the variation of sea level pressure and atmospheric circulation in the western North Pacific and northern Asian continent, is suggested in the most of related studies.

We investigate the provenance of detrital garnets in Middle-Upper Jurassic sandstone of the Mino terrane, an accretionary complex in Southwest Japan, based on their chemical composition. The garnet grains in the Mino sandstone are mostly Fe-rich (almandine) and slightly Mg-rich (pyrope) species derived from high-grade metamorphic and intermediate to acidic plutonic rocks. The composition and interpreted origin of the garnets are generally consistent with those of metamorphic and igneous rocks of the Yeongnam Massif on the Korean Peninsula, a possible source region suggested in previous studies. In addition, two single grains of chromian spinel, an accessory mineral found in mafic to ultramafic rocks such as mantle peridotite, were found in one of the Mino sandstone samples. This finding suggests the possible presence of mafic to ultramafic rocks in the source area. The results of this study provide complimentary evidence for establishing a comprehensive tectonic and paleogeographical framework for the Mesozoic East Asian continent.

A cyclopoid species from several salt marshes and estuaries on the west coast of South Korea were identified as Halicyclops continentalis Ueda and Nagai, 2009, recently described from Ariake Bay at northwestern Kyushu, Japan. Detailed examination on the Korean specimens justifies Ueda and Nagai's proposition that the H. sinensis sensu Tai and Chen, 1979 formerly known from the Chinese coast of the Yellow Sea should be identical to H. continentalis. Furthermore, this report reinforces their assumption on the geographical distribution of H. continentalis, that is, the Ariake Bay population is a continental relict of the East Asia continent. Herein, a redescription of the species is provided on the basis of the Korean specimens, with a comment on the morphological comparison among three populations around the Yellow Sea.

The central-western Korean Peninsula contains records of an Early Mesozoic collisional event related to the final amalgamation of the East Asian continent. Here, we present a renewed geologic map of the Deokjeok and Soya islands in the central-western Korean Peninsula and its explanatory note. Our geologic map was based on a detailed investigation of the northeastern area of both islands, which is characterized by a complex fault and shear zone system that accommodated the crustal deformation related to the Mesozoic post-collisional orogenic collapse and the subsequent structural inversion. We suggest future directions of study aiming at addressing issues regarding the deformational responses of crust to the Mesozoic tectonic transition and orogenic cycles.

To reduce the cost and the time of transport in Eurasian railroad networks such as TKR, TCR and TSR owing to the problem of different track gauges (narrow/standard/broad gauge), it is important to develop the gauge - adjustable wheelset system to adapt easily to these gauges. The gauge - adjustable wheelset system in the transcontinental railway have been proposed as a more effective way in comparison with other techniques for overcoming difference in track gauges. Assume that the freight train with gauge adjustable wheelset system is running from domestic train network to TCR, TSR in Eurasian continent, it is necessary to estimate the safety of this system. This study is evaluated at examination of safety for freight train with gauge adjustable wheelset system by simulated durability analysis. Moreover, the predicted fatigue life at running track using the durability simulator was verified by the durability test according to UIC standard.

The influence of soil particles on TSP transported from China contient to Seoul by the Yellow sand phenomenon was investigated from the analytical results of TSP during three years, April 1988 through May 1991. The TSP was collected by a high volume air sampler abour five times a month, and then analyzed by A.A.S. and UV-Visible spectrophotometry. During the Yellow sand phenomenon, the mean concentration of TSP at Seoul was about 578 $\mug/m^3$ and three times higher than that in the ordinary time which was about 194 $\mug/m^3$. The mean contribution of soil particles calculated by Al content to TSP was 28% in the ordinary time, but the degree of contribution jumped to about 60% during the Yellow sand phenomena. The concentration of soil particles transported from China continent to Seoul was estimated to be 175.1 $\mug/m^3$ on an average(104 $\mug/m^3-231 \mug/m^3$).

The Antarctic soft-shelled clam, Laternula elliptica is widely distributed in shallow waters around the Antarctic Continent and islands. This bivalve species occurs in densepatches particularly in sheltered but frequently ice-impacted areas. This species mostly occurs at atound 20-30 m depth and is rarely found at depths shallower than 5 m where ice abrasion by drifting or grounded icebergs is severe. It burrows deep into sedimint(frequently >50 cm), which seems to be primarily a means for avoiding ice impacts. A pair of stout and highly extendable siphons appear to be a morphological reature to feed in the ice-scoured substrates while staying deep in the sedimint. As one of the largest bivalves in the Antarctic waters, L. elliptica appears to grow rapidly, reaching to a shell length of approximately 100 mm in 12 or 13 years. L. elliptica feeds sctively during summer when food is sufficiently provided, implying that food may be the most inportant fator regulating the growth. Seasonal variations in food availability, and metabolic process in starvation condition possibly during winter, however, are yet to be further investigated.
