This study aims to investigate national image of South Korea held by russians. Surveys(based on Free-association Image) and discussion were conducted on LiveJournal (internet blog) with russian netizen. A national image is influenced by a subjective perspective rather than an objective one. Therefore, an image can differ substantially from reality. Futhermore, it takes a long time to change an established image, particularly to a positive image. According to the results, the image of South Korea were dominated by unstable political situations, especially factors related to North Korea. In addition, based on Free-association image, thinking about Korea or Korean, most russians recognize Korea(South) with North Korea. Above all Russians recognize Korea, basing their images on factor of the past or their neighbors-russian korean- or famous Korean brand like Samsung, LG, Hyndai, "Dosirak". Russian netizen did not recognize South Korea as one of leading countries in Asia, paying little attention to South Korea compared to China or Japan. We belive that it is necessary to consider these situations in future efforts to enhance the national image of South Korea.

Ginseng and ginseng products are distributed in approximately 190 countries around the world. The size of the ginseng market varies by country and there are no accurate statistics on production and distribution amounts per country. Therefore, it is difficult to make predictions about the global ginseng market. Governments and ginseng trading companies are in need of comprehensive data that shows the current status of the ginseng market to help them establish effective import, export, and sales and marketing policies. To addressthis need, this study examines the approximate size of the world ginseng market based on estimates of recent quantities of ginseng distributed in specific country as well as production by major ginseng producing countries. In 2018, global ginseng production was about 86,223 tons based on fresh ginseng. China produced 50,164 tons, South Korea 23,265 tons, Canada 11,367 tons, the US 1,285 tons, Japan 30 tons, and other countries a combined 112 tons. The value of global ginseng production is estimated to be approximately $5,900 million, with $2,870 million (48.6%) in China, $2,489 million (42.2%) in South Korea, $478 million (8.1%) in Canada, $54 million (0.9%) in the USA, $4 million (0.1%) in Japan, and $5 million (0.1%) in other countries. The value of ginseng products consumed for the last five yearsin South Korea was $1,162 million in 2014, $1,280 million in 2015, $1,548 million in 2016, $1,638 million in 2017, and $1,762 million in 2018, showing that the market has been increasing in recent years. In particular, the Korea Ginseng Corporation (KGC), the biggest global ginseng company in South Korea, recorded sales of $1,207 million in 2018. This represents about 69% of the South Korean ginseng market, and about 20% of global production. Since interest in alternative medicine and health food among consumers is increasing globally, the market for ginseng is expected to expand into the future.

Characteristics of precipitation in South Korea during the 2016 Changma period (6/18~7/30) are analyzed in great details. El $Ni{\tilde{n}}o$-induced tropical Indian Ocean (IO) basin-wide warming lasts from spring to early summer and induces the western North Pacific subtropical high (WNPSH) circulation anomaly through an equatorial Kelvin wave during the 2016 Changma period. Along the northern edge of the WNPSH, strong precipitation occurred, in particular, over eastern China and southern Japan. During the Changma period, South Korea had the near-normal mean precipitation amount (~332 mm). However, about 226 mm of rain fell in South Korea during 1 July to 6 July, which amounts to 67% of total Changma precipitation in that year. Upper-level synoptic migratory lows and low-level moisture transport played an essential role, especially from 1 July to 3 July, in triggering an abrupt development of fronts over the Korean Peninsula and the eastern continent China. The front over the eastern China migrates progressively eastward, which results in heavy rainfall over the Korean peninsula from 1 to 3 July. In contrast, from 4 to 6 July, the typhoon (NEPARTAK) affected an abrupt northward advance of the North Pacific subtropical high (NPSH). The northward extension of the NPSH strengthens the Changma front and induces the southerly flows toward the Korean peninsula, giving rise to an increase in heavy rainfall. The NEPARTAK is generated due to interaction of the Madden-Julian Oscillation (MJO), equatorial Rossby wave and Kelvin waves.

In the global economy, trade is not confined in geological boundaries, enhancing the international relation among countries. However, the trade tension between the largest economy and the second-largest economy raise concerns among the world economies, enhancing the uncertainties around world. In particular, the trade tension between the two countries is highly related with South Korea's trade balance, because the country is highly dependent on the trade with the two countries. Given this, we analyzed the news editorials published in Korean quality newsaper, with related to U.S. and China Trade War by looking at the ideological perspectives of news outlets or journalists to the issue within the framework of critical discourse analysis. In particular we gave a special attention to the attitude to each country in order to investigate their ideological stance to the country, following van Dijk (1998)' ideological square. The results are as follows: first, the Chosun Ilbo emphasized 'their' bad properties directly and aggresively, while the Hankyoreh designated the U.S. as a member of an out-group, thus mitigating 'our' bad quatilies; Second, the two strategies of emphasis and mitigation enabled both newspapers to reinforce in-group homogeneity and out-group exclusion. Thus, we could conclude that the editorial is a clear indicator to show the news outlet's ideological stance to each country in regard to the trade issue.

In accordance with the time series of rainfall in summer (June, July and August) in South and North Korea for recent 28 years (1981-2008), rainfall is substantially increased in South Korea since 1996, while it is significantly decreased in North Korea. In particular, the decreasing tendency of rainfall in summer in North Korea is more definitely observed during the $2^{nd}$ rainy season (late August - mid September) in intraseasonal variation. Such a feature is also confirmed in the spatial distribution of oscillation pattern between South and North Korea on the basis of 1996 which is obtained by empirical orthogonal function analysis using the summer rainfall observed in all weather observation stations in South and North Korea. For the decreasing tendency of rainfall in North Korea, it is found that northeasterlies from anticyclonic circulation centered on around Baikal Lake weaken convective activity during summer. On the contrary, the increasing tendency of rainfall in South Korea is related to the strengthened cyclonic circulation in the southern region of China and accordingly, enhances southwesterlies in South Korea.

This study examines the technical level of North Korea's S&T and identifies areas for potential North-South cooperation. First, North Korean media is analyzed for situations and trends from 2010 to 2015. Despite some commendable achievements, North Korean S&T remains lacking in basic science and commercialization potential. Despite an awareness of the importance of international cooperation, North Korea is hampered by international sanctions and their own caution, consequently concentrating their efforts on China. Details of their cooperation reflect their interests and needs to a certain extent, although their collaborations were mainly in the form of meetings and conferences rather than active joint research. To assess the potential areas of cooperation with South Korea, this study also draws on interviews with NGOs and professionals working with North Korea. The country's present situation is analyzed and some practical examples of possible cooperation is suggested. North Korea has the potential to expand its cooperation not only with South Korea but with many other countries. North Korea also promisingly expresses interest in cooperation.

SeaWiFS자료를 Maximum Normalized Difference Carbon Index(MNDCI) 알고리즘을 이용하여 추정된 particulate organic carbon(POC)는 장강에서 유입된 담수의 영향을 받는 동중국해에서 시/공간적 해양환경 변화를 조사하는데 사용했다. 10년 평균한 POC 농도는 (1997년-2007년) 뚜렷한 계절적 변화를 보인다. POC 경년 변화는 전체 지역 평균값과 표준편차를 이용하여 세 개의 지역으로 나누어 평균한 결과에서 1998년 이후 꾸준한 감소를 보이는 장강과는 달리 감소되는 경향이 관측되지 않았다. 자세한 POC 시/공간적인 변화를 관측하기 위하여, 2000년부터 2007년까지 여름철 (6월-9월) 자료를 선정하여 empirical orthogonal function(EOF) 분석을 실시하였다. 첫 번째 성분은 장강으로부터 유입되는 담수의 영향으로 공간적인 변화가 이루어졌다. 두 번째 성분은 장강의 유출량과는 약한 상관관계를 보이고, 공간적으로 남-북 방향의 변화가 관측되었다. 2000년부터 2003년까지 상대적으로 높은 POC 분포는 연구지역 남쪽 부분에서 나타난다. 2004년부터 2007년까지 이런 변화는 연구지역 북쪽 부분에서 관측되었다. 장기적인 변화는 방류량의 감소에 의한 영향보다는 공간적인 변화에 기인한 것으로 사료되며, 이는 현장 관측자료에서 유사한 결과를 보였다.

Most literature on the "comfort women" social movement focuses on the case of Korea. These works tend to transpose the meanings generated by South Korean organizations onto the transnational network, assuming certain homogeneity of repertoires and identities among the different social actors that comprise this network. Even though there is some degree of consensus about demands, repertoires, and advocacy strategies at the international level, does this same uniformity exist at the national level? In each country, what similarities and differences are present in the laboratories of ideas, relationships, and identities of social actors in the network? Symbolically and politically, do they challenge their respective societies in the same way? This article compares this social movement in South Korea, China, and Taiwan. My main argument is that the constitutive base for this transnational network is the domestic actions of these organizations. It is in the domestic sphere that these social actors reinforce their agendas, reinvent their repertoires, transform their identities, and expand their submerged networks, allowing national movements to retain their latency and autonomy. Following Melucci's relational approach to the study of social movements, this research is based on a qualitative analysis of institutional documents, participant observation, and open-ended interviews with members of the main social actors.

The Chandi Borobudur was likely constructed around 800 AD, during the period of the Sailendra dynasty in central Java, Indonesia. The Chandi Borobudur have 1460 narrative panels of reliefs which are distributed from the hidden foot to the fourth gallery. The 160 panels show various scenes of actions producing the corresponding results according to the Karmavibhanga(分別善惡報應經) text. Blameworthy activities with their purgatorial punishments and praiseworthy activities with their subsequent rewards are both shown. The 120 panels depict the biography of Buddha according to the Lalitavistara (方廣大莊嚴經) text. The 620 panels depict stories from Jatakas (本生譚) and Avadanas (譬喩經). The stories of 560 panels are based on Mahayayana (入法界品, 488 panels) and Bhadrucari (普賢行願讚, 72 panels) of Gandavyuha (華嚴經) text. In this study, among the 120 narrative reliefs which tell the life story of Buddha according to the Lalitavistara text in Chandi Borobudur, the images of Birth of Siddhārtha(誕生), The Great Departure (出家), Attaintment of Enlightenment (成道) and The First Sermon (初轉法輪) have been compared with the images of biography of Buddha showing in Ancient India, Gandhara and South India, and China. From a historical perspective of cultural exchange, Borobudur is very important site because it is located on the south route of transmission of Buddhism from India to South Asia, China, Korea and Japan. Study on the reliefs sculptured on the wall of Chandi Borobudur provide us information to understand the process of spreading and changes in styles of Buddhist arts.
