The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.

In order to identify the current state of the $CO_2$ concentrations at the Gosan site in Jeju, the data from the Gosan station was compared with the ones from domestic and foreign sites registered in the World Data Centre for Greenhouse Gases(WDCGG). As a result, the $CO_2$ concentrations in the Asian region including Gosan site were higher than in the other continents, which can be explained that the $CO_2$ emissions in the Asian region have been rapidly increasing due to the recent economic growth. In comparison with ther Asian-Pacific sites (i.e., Ryori, Waliguan, and Mauna Loa), Gosan site showed the highest $CO_2$ concentrations because this site can be easily affected by China emissions. With the trajectory analysis and the ratios of air pollutants, we found that the high concentrations of Gosan site in January were mainly caused by the long-range transport from China, while in August the high concentration in the night time by the stagnation and the active plant respiration. Also, in May and November it occurred as the polluted air from China was transported with migratory cyclone.

The appearance of abnormal weather caused by climate change have both direct and indirect impact on the society. Especially, agriculture is brought up as a socially important interest having direct impact of climate change in growth and harvest of crops. This study aims to perform vulnerability assessment for the South Korea's two main imported grains, maize and wheat. The production vulnerability assessment of maize and wheat in USA and China to temperature variability, which has a great impact in production, is performed. First, grain cultivation period which affects productivity of main grain production country was selected based on the main cultivation period from several references and previous studies. Then, Intergovernmental Panel on Climate Change AR5 greenhouse gas scenario RCP(representative concentration pathways)8.5 scenarios was used to select the future climate that correspond to the cultivation period of maize and wheat for each producing country. According to the result of production vulnerability analysis using adaptation (temperature changing trend) and sensitivity(temperature variability), the productivity of wheat was higher in USA, while productivity of maize was higher in China. In the future, the result showed that productivity of all two grains will be favorable in USA. The result of production vulnerability assessment through this study can later be used as a preparation data for the coming fluctuation in grain price due to climate change.

Marine heatwaves (MHWs), referring to anomalously high sea surface temperatures, have drawn significant attention from marine scientists due to their broad impacts on the surface marine ecosystem, fisheries, weather patterns, and various human activities. In this study, we examined the impact of the distribution of Changjiang diluted water (CDW), a significant factor causing oceanic property changes in the East China Sea (ECS) during the summer, on MHWs. The surface salinity distribution in the ECS indicates that from June to August, the eastern extension of the CDW influences areas as far as Jeju Island and the Korea Strait. In September, however, the CDW tends to reside in the Changjiang estuary. Through the Empirical Orthogonal Function analysis of the cumulative intensity of MHWs during the summer, we extracted the loading vector of the first mode and its principal component time series to conduct a correlation analysis with the distribution of the CDW. The results revealed a strong negative spatial correlation between areas of the CDW and regions with high cumulative intensity of MHWs, indicating that the reinforcement of stratification due to low-salinity water can increase the intensity and duration of MHWs. This study suggests that the CDW may still influence the spatial distribution of MHWs in the region, highlighting the importance of oceanic environmental factors in the occurrence of MHWs in the waters surrounding the Korean Peninsula.

The Northern Song Dynasty Period (北宋時代) was a drastic transitional era in all aspect of Chinese society including the politico-economic system, ideology and cultural trait. These changes that began in the late Tang (唐) Dynasty Period accomplished in the Northern Song Dynasty. In this phase, the fundamental change influenced in all institutional area; and among them, the capital city planning and its associating building technology to pile stone walls shows one of the significant change of those time. Based on the geographical factor, confluences of many rivers, the Kaifeing (開封) area where the BianLieng palace had developed as a political and economical centre since the Tang Dynasty when the Grand Canal was constructed. According to archaeological researches, the central city structure of Dongjing Walled Town was begun to plan in the late Tang Dynasty and formed in Five Dynasties. The fundamental functional change of city completed in the Midnorthern Song Dynasty. In spite of the relatively late beginning of archaeological investigations to Kaifeng Walled Town and Dongjing Walled Town due to unfavourable natural environment, excavations inaugurated since 1981 have achieved the significant investigations including the actual measurement and excavation to the outer wall, the preliminary excavation to the inner city area, the investigation and excavation to the royal palace of Song and the survey to the royal palace of King Zho in the Ming (明) Dynasty. These surveys have provide important data to reconstruct the 변량 palace, and elucidate the characteristics of city plan in the Dongjing Walled Town and the institutional change of capital city plan of the Northern Song Dynasty. The basic layout of Dongjing Walled Town reflect the realisation of ideality of the late Chinese medieval capital city structure that establish the commercial and economic centre based on the intensification of emperor's power by means of the organisation of ethical institution and the development of commercial economy. Firstly, the central place of the Kaifeng area is encircled with triple walls. This emphasise the authority of emperor located on the summit in the hierarchical ethic system succeeding to the main capital city plan of the late phase of ancient China. Secondly, the location of Dongjing Walled Town was decided by the transport network and the commercial function and defence function. Thirdly, this site shows the change of city structure and landscape of the Northern Song Dynasty. The closed Fengri (坊里: block) system transferred the open Jiexiang (街巷: road) system. Fourthly, the capital city was characterised by the free market trade and the diversification of market place. Fifthly, a convenient transport network in the Bian River, a centre of the Grand Canals, enabled to construct the Kaifeng Walled Town. Therefore, the Northern Song Dynasty continuously accomplished the developed water system as concerning about the utilisation of waterways after the construction of city.

When analyzing make-up trends of figures shown in portraits of different eras in Chinese painting history, you can see that red color was used much. This can be because the red color is the most outstanding among all the colors and was most preferred by ancient people, as the color of the sun, the blood, and the sacredness. The women in the Tang Dynasty was especially using the red color much. Though Seongrihak (Neo-Confucianism) in Song Dynasty was the governing ideology, it had an influence even upon its aesthetics. Thus, during Song Dynasty, the beauty of logos appeared too. This phenomenon showed a conservative tendency even in make-up as well as in costume, thereby the concept of clear and elegant beauty was emphasized. The real figure in the Ming and Ching Dynasty, was so young and weak as a sample of a delicate woman that a woman who had feminine beauty was regarded as an ideal type. The feminine image had been gradually generalized from the literary works in the latter half of Ming Dynasty. However, the painters in the era still preferred the beauty of a healthy woman. That tendency probably had an influence even upon make-up culture that was shown in portrait. As an analysis result of make-up culture in Chinese portrait paintings, it reveals that ancient make-up trends much reflected the social and cultural phenomena of the periods.

Caulis Bambusae in Taenia is widely used in Korea and China due to its various pharmacological activity. The present study aims to investigate the effect of the methanol extract of Caulis Bambusae in Taenia (CB) from Phyllostachys nigra Munro var. henonis Stapf (Gramineae) on amyloid ${\beta}$ protein (25-35) $(A{\beta}\;(25-35))$, a synthetic 25-35 amyloid peptide, -induced neurotoxicity using cultured rat cortical neurons. CB, over a concentration range of $10-50{\mu}g/{\mu}l$, inhibited the $A{\beta}\;(25-35)\;(10\;{\mu}M)$-induced neuronal cell death, as assessed by a 3-[4,5-dimethyIthiazole-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and the number of apoptotic nuclei, evidenced by Hoechst 33342 staining. CB $(50\;{\mu}g/{\mu}l)$ inhibited glutamate release into medium induced by $10\;{\mu}M\;A{\beta}$, (25-35) which was measured by HPLC. Pretreatment of CB $(50\;{\mu}g/{\mu}l)$ inhibited $10{\mu}M\;A{\beta}$ (25-35)-induced elevation of cytosolic calcium concentration $([Ca^{2+}]_c)$, which was measured by a fluorescent dye, fluo-4 AM, and generation of reactive oxygen species. These results suggest that CB prevents $A{\beta}$ (25-35)-induced neuronal ell damage in vitro.

We study, in this paper, on the decorative design of the Treasure-architectural form for the Silla Buddhist reliquary and this research went through the observation on the Buddhist Reliquaries of the Song-Lim-Sa, the Eastern-Western three floor pagodas in the Kam-Eun-Sa, the three floor pagodas in the Bul-Guk-Sa and the reportedly discovered Nam-Won. The Buddhist reliquaries of these 5 Reliquaries, when compared with those of China and Japan in the same period, they worshiped the Buddhist reliquary as a Buddhist God itself and put them as a part of the architectural decoration, being installed in the construction forms. In the form and the composition of the architecture, we can see those having been designed with very detailed and brightly decorated form. The Buddhist reliquaries in the Song-Lim-Sa and Kam-Eun-Sa, the most important ones in this research, were in a royal palace shape having completely the altar part, interior space part, and the ceiling part, which inform us the whole structure of the architecture in details. In particular, for the case of Kam-Eun-Sa, the columns in the shape of bamboo trees, the expression of the gates, the terrace of double parts formed of word-shape Man, and the statue of a general with superhuman ability in the shrine explain us the description of the Gyun-Bo-Tap-Pum of Lotus Sutra. After all these researches, we conclude that the Buddhist reliquaries in form of the Treasure-architecture represented the architectural style of the same period as a form of industrial arts and we can see that they tried to use all of their highly skilled and talented methods to describe the Buddhist Pure Land.

A battle royale game is a multiplayer video game genre that blends the survival and exploration with last-man-standing gameplay. The genre has been hot in recent years and the 'Player Unknown's Battleground' produced by Korean enterprise PUBG had been the hottest during 2017 and the first half of 2018. However, a similar battle royale game 'Fortnite' became the game of the year in 2018 and the Player Unknown's Battleground sustains the predominance only in Korea and China. In this paper, we investigate the game structure of those two games on combat, survival, farming and charging elements, We also conduct a user survey on what might be the weak point of the Player Unknown's Battleground and why they choose Fornite among users played both but currently play Fortnite. The result shows that the Player Unknown's Battleground sustains the advantage on battle elements but creative charging policy and the efficient survival elements are the reasons of choosing Fortnite between the two.
