Mesoscale low is often observed over the downstream region of the East Sea (or, northwest coast off the Japan Islands) during East-Asia winter monsoon. The low system causes a heavy snowfall at the region. A series of numerical experiments were conducted with the aid of a regional model (MM5 ver. 3.5) to examine the formation mechanism of the mesoscale low. The following results were obtained: 1) A well-developed mesoscale low was simulated by the regional model under real topography, NCEP reanalysis, and OISST; 2) The mesoscale low was simulated under a zonally averaged SST without topography. This implies that the meridional gradient of SST is the main factor in the formation of a mesoscale low; 3) A thermal contrast (>10˚C) of land-sea and topography-induced disturbance served as the second important factor for the formation; 4) Paektu Mountain caused the surface wind to decelerate downstream, which created a more favorable environment for thermodynamic modification than that was found in a flat topography; and 5) The types of cumulus parameterizations did not affect the development of the mesoscale low.

2006/2007년 한반도에 이상적인 온난 겨울을 가져온 원인을 규명하기 위해 동아시아 지역 대기 순환의 특징을 조사하였다. 2006/2007년 겨울철 동안 대기 상태는 시베리아 고기압 및 알류산 저기압의 약화, 한반도 부근으로 하층 남동류의 강화, 일본 남쪽으로 상층 제트의 약화로 특징지워질 수 있다. 이러한 패턴은 시베리아 지역(60-140E)으로 블로킹 흐름이 없을 때 나타나는 대기 상태와 상당히 밀접한 관련성이 있다. 아울러 엘니뇨 및 북극 진동 역시 이런 패턴을 만들어 내는 것으로 보인다. 따라서, 블로킹과 무관한 대기 상태, 엘니뇨 및 양의 북극 진동이 원인이 되어 1958/1959-2006/2007 기간 중 2006/2007 겨울철에 한반도에서 가장 기온이 높았던 것으로 판단된다.

동아시아에서 일산화탄소의 지역적 배경 농도 수준을 분석하기 위해, 1991년부터 2004년까지 장기간 중국 Waliguan(WLG), 몽골이아의 Ulaan Uul(UUM), 한국의 태안반도(TAP), 일본의 Ryori(RYO)에서 관측한 일산화탄소 농도를 분석하였다. 연평균 일산화탄소 농도는 WLG(135±22ppb), UUM(155±26ppb), RYO(171±36ppb), TAP(233±41ppb) 순서로 높은 농도를 보이고 있었다. WLG를 제외하고 전체적으로 봄철에 높고 여름철에 낮은 계절 변동의 특징은 동아시아 다른 지점들에서도 공통적으로 나타나고 있다. TAP는 WLG, UUM, RYO와 비교하여 전체 계절에 높은 일산화탄소 농도를 보이고 있으며 히스토그램에서 넓은 농도 분포를 보이는데 동아시아 대륙, 특히 중국의 가까운 풍하측에 위치하고 있어 광역적 대기 오염의 영향이 크기 때문이다. TAP는 중국 동부 지역을 경유하는 RPC가 봄, 가을, 겨울에서 높은 농도를 나타내었고, 여름철에는 저위도 북태평양으로부터의 OBG에 의해 낮은 일산화탄소 농도를 갖고 있는 해양성 기단의 영향을 받고 있다. NOAA 위성 영상과 GEOS-CHEM 모델 시뮬레이션은 중국 남동부 연안으로부터 황해를 거쳐 한반도와 동해로 확산하고 있는 광역적 대기오염 이동 사례를 확인하고 있다.

동아시아 지역에서의 원자력 수요는 경제 발전을 뒷받침하기 위해 급격히 증가하고 있다. 9.11 사태 이후 전 세계적으로 핵비확산은 세계적인 현안이 되고 있으며 이와 함께 타 지 역과는 달리 동아시아 지역에서는 향후 10년 후 몇몇 국가들이 원자력을 새로이 도입하려는 움직임이 있다. 이와 같은 현안에 대처하기 위해 공급 확약과 핵비확산을 목적으로 새로운 지역적인 다자간 원자력 협력 체제가 제안되었다. 이러한 새로운 제안은 신뢰성 증진, 자발적 참여 및 동기 부여의 원칙을 바탕으로 하고 있다. 또한 동아시아에서 다자간 체제를 실행하기 위해 단계적인 접근 방법을 제안하고 있다.

We had the first committee meeting of the East Asia VLBI Consortium during the EAMA6 meeting held in Seoul. A VLBI network composed of telescopes in the East Asia region could provide extreme properties, and the coordination of them has been expected. The Committee of the East Asia VLBI Consortium is a standing committee to promote activities of the consortium, in which participating countries at present are China, Japan, and Korea over eight institutes/observatories. Here we introduce the Consortium and Committee.

In this work, the present concentration levels of total gaseous mercury (TGM) are compared among three East Asian countries, Korea, China, and Japan. Comparison of Hg distribution patterns was made by selecting representative figures for each type of land use among those three countries. The results of the analysis indicate that Hg concentrations within a country can fall into a wide range due probably to the diversity of source processes. It is seen that the urban areas of China and Japan generally exhibit large spatial variability with notably high Hg levels (above 10 ng m-3), compared to their Korean counterparts. Although the presence of high Hg levels in Chinese locations can be accounted for by the major man-made source processes (e.g., the use of coal), the causes of unexpectedly high Hg data in Japanese sites appear to be rather complicated. The Hg concentration levels in relatively remote locations however show much reduced values, above 3 ng m-3, which is still higher than the typical background concentrations of 1 to 2 ng m-3 in Europe or America. Considering that the presence of unusually high Hg levels in urban areas of Asia is the consequence of man-made activities, the prevalence of excessively high Hg values in certain regions of the Asian continent needs further research to accurately assess the fundamental picture of Hg geochemistry in the East Asia.

Fiften new species of the genus Stenoloba Staudinger (Lepidoptera, Noctuidae, Bryophilinae) are described in this second part of the article, with 21 colour photos of adults and 33 genitalia figures.

In the revision of the genus Stenoloba Staudinger, 1892, which distributed mostly in the Oriental region(South-East Asia) and partially in Manchurian subregion of the Palaearctic region, 47 species including 25 new species and three new subspecies are recognized. In the first pat of this revision, 21 species with descriptions of 10 new species and two new subspecies are reviewed, with illustrations of 42 genitalia and 29 colour photos of adults. One species, Stenoloba albiangulata (Mell, 1943), comb. nov. is newly combined and transferred to this genus. The 2nd part will include 26 species, with descriptions of 15 new species.

Main theme of this study is the acceptance phase of western architectural culture in modern east-north asia through a series of actual survey and typological analysis of existing church buildings in modern Korea. China. Japan. For this study, 126 modern church buildings of Korea, China, Japan are selected. Also, main subject of this study has deal with the side of culture - thought which background of christianity acceptance and acceptance mind of acceptance main-body, culture adaptation and transformation based on characteristic culturalization of Korea, China, Japan. Especially, I would consistently tried to see the acceptance phase of western architectural culture according to differential acceptance mind of acceptance main-body based on characteristic culturalization of three countries. Conclusively, in the point of view of western architectural culture acceptance phase, it could be said that Korean church architecture had characterized as a blending phase of the two eclectic architectural culture. And in the case of china, as a coexistance phase of the two architectural culture with more western style-oriented. On the other hand, Japanese church architecture had characterized as a syncretism phase of the both traditional and western architectural culture, though it is eclectic style-oriented. Therefore, it is thought that different acceptance mind of western culture had main factors caused of differential acceptance phase, when the two architectural culture, the traditional and the western, encounters.

[Goshogi] which is held from 9th to 16th January, every year is the Buddhist service of praying for the soul of Shinran's (l173~1262) after death. It is the most majestic high-filling style and also unparalled in the annals of Japanese history in sacrificial offering. Shinran was horned in the Fujiwara's family. And not only he believed Prince Shodoku's belife but also retired to the mountain to enter the priesthood by it. Prince Shodoku built Horyu temple which is the typical temple of Nara ages. Buddism was transmitted from Korean peninsula, three countries of Silla, Bekje and Kokuryo effected on many field of Japnese culture during that ages. At the same time, Kasugadaisha and Danjanjinja of Shinto religion was built by Fujiwara Family. Both of them was Buddhist temple before. Throughout like these historical background, the facts what the religious services and the sacrificial offerings for Prince Shodoku, Wakamiyasai of Kasugas' and Kakitsusai of Danjanjinja must be influenced from Korean Peningula. So the dietary culture of the religious rites and traditional customs between two countries could be thought the relation with a narrow stream strait. But among them, in the size, color and shape, the cooking method and technique in the usage of rice powder and sugar, it is tops in value. The noteworthy points of the thought were as follows: 1. high-filling style of the sacrificial offerings what is mixed and harmonized with Buddhism, Confucious, Sharmanism, Toaism and Korean traditioal customs. 2. eating together of god and human. 3. the fusion of gods and Buddha.

꼭지매미충(Macrosteles striifrons)은 각종 농작물을 가해하고 식물병원균을 매개하며 동부아시아 지역에 널리 본포하고 있으나, 종내변이는 물론 근사종과의 형태적 유사성이 심한 주요해충 중의 하나이다. 본 조사는 동부아시아 6개 지역에서 선발된 꼭지매매충의 수컷 8개체군을 대상으로 총 23개 정량형질에 대해 각 주요지역 계통간 이소적 특성, 기주식물 및 계절 등의 요인에 따른 동소적 특성, 우열도 및 그 상호관련성등을 알아보기 위해 전자영상 미세측정방식과 고급 다변량 전산통계 분석법에 의한 종내 수리분류를 실시하였다. 그 결과, 지역별 평균분리도가 최저 90% 이상으로 매우 높았고, 기주별 및 계절별 등에 따른 종내 개체군간 평균분리도는 80% 이상으로 나타났다.

Soybean was originated from the regions of Manchuria where it was processed into Dujang, the fermented soybean souce. It was not until the Han dynasty in China that 'Shi', one type of Dujang, was introduced. 'Shi', which is also known as 'Sanguk'(loose soybean Meju), is made by first boiling and then fermenting the kernel of cooked soybean. It was admitted by the Chinese scholors that the 'Shi' which was used in China was introduced from Manchurian, the neighboring people to China at that time and the concestor of Korean. 'Maljang' is a form of caked-shaped 'Meju' which is made by formenting cooked and mashed soybean. The 'Maljang' of Manchuria was introduced to China, where it was called 'Maldo'. This fact is stated in a book, 'Saminwolyong', written during the 2nd century. 'Maljang' is presently used in Korea, but China has abandoned the use of 'Maljang' since the 6th century. It was introduced to Japan from Korea around the 7th century, and is remained in a few local regions. Although the term 'Jang' is representing all sort of fermented soybean preducts, including 'Shi' and 'Maljang', today, the definition of 'Jang' differs between China and Korea. According to the Chinese definition of 'Jang'. it is fermented soybean mixed with other cereal Koji. 'Jang' was first mentioned in 'Jaeminyo sool' in China and it was lator introduced to Japan However, in Korea, the Chinese type of 'Jang' was not commonly used due to the popularity of 'Maljang'.
