중국이 명실상부한 세계적 강대국으로 부상하고 있다. 2011년 현재 보편적 국력으로 보았을 때 중국은 미국 다음으로 강한 국력을 가진 국가로 아시아를 넘어 세계적인 패권국으로 성장하고 있다. 중국이 이와 같은 강대국으로 부상하면서 동아시아에서 미국중심의 국제정치질서가 도전받고 있으며, 특히 동아시아 해양패권을 놓고 기존의 패권국인 미국과 경쟁이 본격화 되고 있다. 이러한 중국과 미국과의 경쟁은 동아시아의 해양을 무대로 진행되고 있어 해양을 통해 국가의 안전과 번영을 유지하고 있는 해양국가인 한국의 안보에 직접적인 영향을 미치고 있다. 중국의 부상에 따른 동아시아 해양에서의 미-중 군사경쟁 배경과 현황, 그리고 이러한 경쟁이 동아시아와 한국안보에 미치는 영향과 대책을 모색해 본다.

A new gastrotrich species of the genus Dendrodasys (Dactylopodolidae) is described on the basis of specimens collected from sublittoral fine sandy bottoms at Uljin, East Sea and at Gujwa, the northeastern coast of Jeju Island, South Korea. Dendrodasys duplus is characterized by a triangular head with lateral lobes extending outward, two pairs of pestle organs posterior to the lateral cephalic lobes, a pair of anterior adhesive tubes, the absence of dorsal, lateral and ventral adhesive tubes, large posterior adhesive tubes arising from the anterior third of the caudal peduncle, and paired testes of different lengths. The genus Dendrodasys is recorded for the first time in East Asia.

본 논문의 목적은 지난 2010년 이후 우리의 수출 대상인 아시아, 북미, 유럽, 중남미, 중동, 아프리카를 중심으로 수출액의 상승률 동향과 변동성 그리고 상관관계와 모형분석 등을 살펴보고 향후 성장 방향을 찾아보는데 있다. 분석 결과 아시아, 북미, 유럽, 중남미, 중동, 아프리카 순으로 높은 수출 비중을 보여주었으며 수출액 상승률은 아시아, 북미, 유럽이 상대적으로 높게 나타났고 전윌대비 변동률은 아시아와 북미가 안정된 움직임을 보여주었다. 이 연구를 통해 우리의 수출액을 증가시키기 위해서는 아시아, 북미, 유럽으로의 수출 향상에 많은 관심을 보여야 할 것이다. 특히 50%가 넘는 아시아 즉, 중국, 일본, 베트남, 홍콩, 대만, 인도 등으로 수출 향상과 수출전략 방안이 필요해 보인다. 아직은 수출 비중이 크지 않지만 향후 중남미, 중동, 아프리카 등의 신시장 개척에도 많은 관심을 가지고 수출향상방안이 체계적으로 진행되기를 기대해 본다.

This paper presents the effects and the regional power distribution of an increase or a decrease of a power reserve by load flow calculations under seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of the South Korea in North-East Asia. In these connections, the types of a power transmission for interconnection consist of the 765kV HVAC and the HVDC. In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. The power flow map is drawn from data simulated and the comparative study is done. In this future, a power flow analysis will be considered to reflect the effects of seasonal power exchanges And the plan of assumed scenarios will be considered with maximum or minimum power exchanges during summer or winter in North-East Asia countries.

In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. Data for simulation were obtained from the 2-th long term plan of electricity supply and demand in KEPCO. The power flow map is drawn from simulated data and the comparative study is done. In the future, a power flow analysis will be considered to reflect the effects of seasonal power exchanges. And the plan of assumed scenarios will be considered with maximum or minimum power exchanges during summer or winter in North-East Asian countries.

Material exposure experiments were performed to evaluate the relationship between air pollution and material corrosion rates based on collaboration with researchers in China, Japan, and Korea. Qualitative and quantitative atmospheric corrosion was estimated from damage caused to bronze, copper, steel, marble, cedar, cypress, and lacquer plates exposed to outdoor and indoor conditions in certain East Asian cities. The effects of atmospheric and meteorological factors on the damage to the copper plates and marble pieces were estimated using a regression analysis. The results indicated that sulfur dioxide produced the most destruction of the materials, especially in South Korea and China. In Japan, the copper plates were damaged as a result of natural conditions and sea salt. Copper was also found to be damaged by the surface deposition of sulfur and chlorine. Meanwhile, marble was substantially degraded by gaseous sulfur dioxide, yet sulfate ions in rain had no effect. Accordingly, the analysis of air pollution from the perspective of material damage was determined to be very useful in evaluating and substantiating the intensity of air pollution in East Asia.

In this study, 15 simple sequence repeat (SSR) markers were used to analyze the population structure of 55 mungbean accessions (34 from South Asia, 20 from West Asia, 1 sample from East Asia). A total of 56 alleles were detected, with an average of 3.73 per locus. The mean of major allele frequency, expected heterozygosity and polymorphic information content for 15 SSR loci were 0.72, 0.07 and 0.33 respectively. The mean of major allele frequency was 0.79 for South Asia, and 0.74 for West Asia. The mean of genetic diversity and polymorphic information content were almost similar for South Asian and West Asian accessions (genetic diversity 0.35 and polymorphic information content 0.29). Model-based structure analysis revealed the presence of three clusters based on genetic distance. Accessions were clearly assigned to a single cluster in which >70% of their inferred ancestry was derived from one of the model-based populations. 47 accessions (85.56%) showed membership with the clusters and 8 accessions (14.54%) were categorized as admixture. The results could be used to understanding the genetic structure of mungbean cultivars from these regions and to support effective breeding programs to broaden the genetic basis of mungbean varieties.
