The bamboo, one of staples of South-East Asia, has 1, 250 species in 46 Genus throughout the world South-East Asia, it's main habitat, has 1, 180 species, while South America has about 70 species or so. Major places of it's production in Asia are Korea, southern China, Japan, Malay, Ceylon, Formosa, and Philipine, but of these, Korea, southern China, and Japan are the most famous places for their production of excellant bamboo. In Korea, Kyongsang-Namdo and Cholla-Namdo are known as it's home, occupying 80 per cent of the total area of bamboo production in this country. Kyongsang-Pukdo, Cholla-Pukdo, Chungehong-Namdo, and Kangwon-do are also known as it's minor production. The importance of the bamboo can not be ignored, considering it's role in the industrial development of this country; the bamboo-ware is indispensable for the culture of laver which annually secures a considerable amount of foreign money. But it has long been regreted that the home-made bamboo-ware is far from being able to meet the ever increasing demand in quantity and is forced to be imported annually. In the light of the above mentioned fact, much interested; I undertook the task of investigating the bamboo in this country, Primarily concerned in it's kind and distribution, and could draw the following conclusions as the first phase of my investigation: (1). The amount of the bamboo accumulation in this country, compared with that of pre-worldwar II, is reduced as much as 300, 000 fagots(on fagot amounts to 25 pieces), and now the acreage of the bamboo field is 32, 200$\textrm{km}^2$s. (2). At a mountian peak in Kunoe-myon Wando-kun Cholla-Namdo, I found out a new specis. (Shasamorpha chiisanensis NAKAI Forma wan-Ponia H. P. CHONG) (3). The kinds of the autogenous wild bamboo in this country are as follows; a). 8 kinds in Sinoarundinaria. (5 Spp; 2 For; 1 Var) b). 1 kinds in Pieioplastus. (1 Spp) c). 2 kinds in Pseudosasa. (1 Spp; 1Var.) d) 4 kinds in Sasamorpha. (2 Spp; 1 For.; 1 Var.) e). 4 kinds in Sasa. (4 Spp) In total there are nineteen(19) kinds of autogenous wild bamboo in this country. When adding to this thethirty five (35) species which the japanese has transplanted in Kyongsang-Namdo Forestry Expreimental stations, there are in all fifty four (54) spe ies in this country. (4). As for the distribution of the Northern limitation of the bamboo growing, I found that Sinoarundinaria nigra OHWI var, Henonis HONDA can be cultivated as for as Kosongkun, Kangwon-Do, andSinoarundinaria pubescens HONDA as for as Clung Chong Namdo, and Sinoarundinaria reticulata as far as chung Chong-Pukdo.

The Republic of Korea (Korea) and the Russian Federation (Russia) are actualizing the cooperation in the Arctic area. As a result, Korean companies have begun to enjoy real economic benefits. However, since there are some troublesome aspects associated with this cooperation, measures that can lead to sustainable development through the supplementation of relevant norms are critical. Russia is also aware of these problems in obtaining economic benefits in the future; cooperation between the two countries should be extended to sufficiently cover this point. The laws related to the region are vague and do not encompass every field. In addition, when it comes to national interests, many situations arise from areas where international and national laws are not clearly harmonized. Therefore, efforts should be made to reflect the interests of both sides and to maintain economic benefits, in case Korea participates in Russia's development of the area, as well as for the legal foundation to reduce negative issues. The Korea-Russia Free Trade Agreement (FTA) negotiation is on the track for the purpose. The two governments should consider various tasks, such as harmonizing with the former FTAs and dealing with the domestic law in accordance with the new FTA. The two countries also have to conduct researches on the efficient use of the FTA and for the 'Sustainable Arctic Development'.

The family Thapariellidae has been reported in only 3 countries since 1990. The objective of this study was to identify Thapariella anastomusa metacercariae in snails in Thailand based on morphological traits using a light (LM) and a scanning electron microscope (SEM). A total of 94 Filopaludina snails were collected and identified as 50 F. martensi martensi and 44 F. doliaris. Metacercariae of T. anastomusa were recovered from the snails by the crushing method. The overall prevalence was 22.3% (21/94), and the mean intensity was 17.0 per snail. The prevalence in F. martensi martensi was 24.0% (12/50) and F. doliaris 20.5% (9/44) with the mean intensity of 18.8 and 14.8 per snail, respectively. SEM revealed traits such as a concave ventral body and well-developed oral and ventral suckers. This study represents the first report of T. anastomusa in South East Asia. While LM and SEM observations provide novel insights into T. anastomusa metacercarial morphology and life history, the trematode's life cycle remains unclear. To date, there has been no report of T. anastomusa causing infections in humans. However, the snails F. martensi martensi and F. doliaris carrying the infective stages of T. anastomosa are frequently consumed by Thai people. This consumption, particularly uncooked snails, may present a risk of Thapariella infections in humans.

The positive and negative opinion to cargo demand of Incheon's SAMT in the near future remains cloudy. Considering port and shipping environmental changes and the logistics situation of China which explains the lack of facilities in Chinese airports, the creating of SAMT cargoes of the Incheon region could catches a favorable opportunity to be a logistics hub in the North-East Asia. On the other hand, as open-sky policy and direct-call service has been carried out between China and N.A.(North America), Incheon could cause a loss of competitiveness in SAMT because the enhancement in the aspect of the connectivity of Chinese airlines and shipping lines makes customer sent to last destination their cargoes whenever they want. In the same context, this paper analyses on conditions of domestic and international SAMT and proposes in this uncertainty future forecasting of SAMT of Incheon by scenario planning according to changes in integrated SAMT, measuring the likelihood of final scenario. This study shows the Sea & Air multi-transport volume will have either slight increase or decrease from the current condition. Consequently, RFS expansion and system & service improvement through strong ties with major cities in China will be required in a short run aspect. Nonetheless, we also need to take domestic & international transportation environment into account in the long run.

Analyzing the observational data of volcanic activities around the northern part of Korean peninsula, the odds of volcano eruption increases continuously. For example, the cumulative seismic moment and frequence observed near Mt. Baekdu show a sudden increased values. In this study, predicting the diffusion of volcanic ash for two cases were carried out by using interactive realtime simulator, which was developed during last 2 years as a research and development project. The first case is Sakurajima volcano (VEI=3) erupted in August 2013. The second case is assumed as the volcanic eruption at Mt. Baekdu (VEI=7) under landing circumstance of typhoon Maemi (August 2003) in Korean peninsula. The synoptic condition and ash diffusion for the two cases were simulated by WRF(Weather Research and Forecast) model and Lagrangian dispersion model, respectively. Comparing the simulated result of the first case (i.e., Sakurajima volcano) with satellite image, the diffusion pattern show acceptable result. The interactive realtime simulator can be available to support decision making under volcanic disaster around East Asia by predicting several days of ash dispersion within several minutes with ordinary desktop personal computer.

Yiguandao missions arrived in Korea no later than 1947. Despite many obstacles, including war and internal dissension, the movement has flourished in South Korea. Today there are three active major lineages and another seven smaller networks. This article relates the movement's overall development in Korea. We begin by discussing key missions dispatched to Korea by Yiguandao's founder Zhang Tianran. The northern port city of Tianjin was key to this effort, in particular a single temple, the Hall of Morality. In Korea the leaders found an unfamiliar cultural landscape that was soon engulfed in war. The Yiguandao missions tended to develop independently, without coordination. In an effort to unify the movement, the Morality Foundation was established in Busan in 1952. The article shows how Yiguandao's subsequent success in Korea is connected to the development of indigenous leadership. Local Korean leadership ousted Chinese members from the Morality Foundation in 1954, and this branch has continued under Korean leadership to this day. The ousted Chinese leaders continued to develop their own lineages. Two major leaders, Zhang Ruiquan and Kim Bokdang, were able to establish enduring legacies. A final section looks at organizational traits that will determine the movement's future prospects in modern Korean society.

Over the past few years, due to the climate change of the earth, the Arctic's sea ice cover is undergoing a historic transformation - thinning, extent reduction in all seasons, and mitigation in the area of multi-year ice in the central Arctic Ocean. These changes allow for increases in maritime access throughout the Arctic Ocean and for potential longer seasons of navigation and possibly transarctic voyage in the summer. These changes also allow more exploration for oil, gas, and other minerals. The Arctic is now an archetype of the complex, multi-dimensional global problems of the twenty-first century. Military security, environmental security, and economic security interact. The potentially enormous economic stakes, sufficient to change the strategic balance among the states of the region, set off competitive pressures for national advantage. Korea, which is heavily dependent upon the sea lane in terms of transportation of its exports and imports, is very much interested in the Arctic sea routes. Korea believes that the Artic sea route, particularly the Northern Sea Route (NSR), could serve as a new useful sea lane, which will enable shorter times between East Asia and Europe, thus resulting in substantial cost saving for ship operators. In addition to shipping, Korea is interested in other Arctic-related maritime industries. Korea, as a leading shipbuilder in the global market, is interested in building ice breakers, drill ships, and other vessels which can contribute to safe operation in Arctic resource development and exploration. Korea, as one of the future stakeholders in Arctic maritime activities, should be ready to foster international cooperation in the region.

우리 나라와 일본, 러시아의 총 44개 관측점에서의 수위 자료에서 조석을 제거, 해입을 계산하여 연별최대양의 해입값, 최대음의 해이값을 구하고 그 값들의 평균을 구하여 각 해안에서 발생하는 해익의 특성을 고찰하였다. 우리 나라 의 경우는 양의해 익과 음의해익 모두 그 진폭이 서해안에서 크고 남해안과 동해안으로 갈수록 점차 줄 어드는 양상을 보였다. 각 관측점에서 발생한 양의해익과 음의 해익의 진폭의 평균을 비교해 보면 서해안의 경우는 음의 해익의 진폭이 양의 해익의 진폭보다 더 크고, 우 리 나라 의 남해안과 동해안 또 일본 서해안의 경우는 그 반대였다. 또한 동해에서는 북부 러시아 해안에서는 해익이 남부 일본 서해안에서는 해익에 비해 상대적으로 큰 결과를 보였다. 국내 각 관측점간의 해익의 연중 최대치를 비교해 본 바에 의하면, 서 해안에서 양의 해익 최대치가 나타난 것은 열대성 저기압에 의한 강풍의 결과이고, 남 해나 동해에서 나타난 경우는 여름철 태풍에 의한 결과였다. 음의 해익의 경우는 거의 대부분 서해, 특히 인천에서 열대성 저기압에 의한 연중 최대치가 나타났다.
