본 연구는 모로베레칸의 잎도열병 저항성유전자를 탐색하고, 이 저항성유전자와 연관된 분자표지를 탐색하기 위해 수행되었다. 도열병에 이병성인 일품벼와 도열병에 강한 모로베레칸을 교잡하여 육성된 140개 BC3F3 계통을 도열병 균계 반응을 통한 저항성 유전자 탐색에 이용하였다.

1420년대 강원도 관아는 일본과의 접촉이 거의 없었고，그때까 지 왜구들과의 접촉은 평화적인 교역으로 이루어지고 있었다. 이러한 일본인과의 교류방식 변화는 조선전기 강원도의 우산도와 울릉도 섬에 대한 정책으로 조선조정에게 알려졌다. 그리고 경상도 의 제포，부산포，그리고 염포 3개의 항구에서 접촉이 주로 이루어진 교역은 수군영의 보호된 지역에서 일본과의 교역통로로 집중되었다. 조선조정은 경상도 삼포에서 성공적으로 일본인 교역을 허용하는 정책을 수행함에 따라 모든 강원도 지역을 일본인들의 출현을 금지하였다. 강원도 지역에는 일본인들이 문인을 가지고 도항할 곳이 없었다. 즉 조선조정은 일본 배가 부적절한 방식으로 해안 수역에 나타나지 못하도록 제한하였다. 강원도 해안에는 섬이 적은 관계로 일본인들이 강원도로 내왕하기 어려웠다. 조선시대 우산도와 울릉도 역사는 일본인 접촉과 교류로 연관되어 있었다.

식용으로 사용되는 산채의 일종인 어수리의 지상부로부터 peroxynitrite 소거활성을 나타내는 성분을 분리한 결과 플라보노이드 성분인 hyperoside와 astragalin이 분리되었다. 특히, 높은 활성을 보였던 hyperoside는 이 식물재료 중 함량도 높아 어수리 잎은 peroxynitrite 과잉생산시 유발될 수 있는 당뇨병, 비만, 고지혈증, 심장질환 등의 예방과 치료에 유익한 식품이라 할 수 있을 것이다.

The purpose of this study is to grasp what characterizes the vegetation base of the natural forest as a latent vegetation in the middle region of Korea and thus to offer basic data when improving the vegetation base in the middle region being built or to be built in the future. The findings of this soil section survey show the following: The soil is brown to red color soil group on the whole. In addition, the soil’s physical features like soil hardness are rated as high level, which results from the fact that the forest soil exits in its natural form under less influence of stamping. The pH of soil shows a weak acidity, like Korean normal soil. Specific electrical conductance is also rated as middle to high level in accordance with the standards of landscape architecture. The Salix koreensis community and the Pinus rigida community are different from other communities in terms of total nitrogen, available phosphate and exchangeable K+ content. Specifically, the two communities are opposed to each other in terms of total nitrogen and available phosphate, while being similar to each other in terms of available phosphate and exchangeable K+ content. This seems to result from the fact that they are located near each other. In addition, the two communities are characterized by the fact that they are distributed at the altitude mean relatively lowest and in the valley. To sum up, the forest soil around Goesan Gun is of middle level on the whole according to the landscape standards, when judging it in terms of vegetation base. Accordingly, it seems that the construction of the vegetation base around Goesan Gun will not require large investment expenses for soil improvement. Also, it seems that the spatial scope of research is needed to expand the basic data on the construction of the vegetation base for the whole middle region of Korea.

In this paper, changes in the intensity (e.g., central pressure and maximum sustained wind speed) of Tropical Cyclone (TC) in summer in the regions located at 30 oN in East Asia from 1988 to 1991 were found. The intensity of TC from 1991 to 2007 was much higher than that of TC from 1965 to 1988. The reason for this was that the frequency of TCs passing China from 1991 to 2007 was much lower than that of TCs from 1965-1988 because a northeasterly wind caused by high-pressure circulation in East Asia got severer along the East Asian coast. Instead, TCs moved from the eastern region of the Tropical West Pacific to Korea and Japan mainly after passing the East China Sea due to the low-pressure circulation strengthened in the subtropical waters of East Asia. In addition, low Vertical Wind Shear (VWS) was created along the mid-latitude regions of East Asia and the main path of TCs from 1991 to 2007. Most of the regions in the Northwestern Pacific showed higher Sea Surface Temperature (SST) from 1991 to 2007, and had a good environment where TCs were able to maintain a higher intensity on the mid-latitude. In particular, a low sensible heat flux occurred due to high snow depth in East Asia in the spring of 1991 to 2007. Accordingly, the lower layer of East Asia showed high-pressure circulation, and the sea surrounding East Asia showed low-pressure circulation. Thus, the typical west-high, east-low pattern of winter atmospheric pressure was shown. The possibility of snowfall in East Asia in spring to be used as a factor for predicting the summer intensity of TC in the mid-latitude regions of East Asia was insinuated. The characteristics of TC in a low-latitude region were the same in Korea. The latest intensity of TCs got higher, and the landing location of TCs gradually changed from the west coast to the south coast.

This study found that tropical cyclones (TCs) formed for fall in 2007 over the western North Pacific were distributed in high-latitudes comparing to 56-year (1951-2006) climatological mean. The frequency and latitude of TC genesis became higher than 56-year climatological mean from September onward in 2007 and all the TCs that formed to the north of 20°N was also distributed after September in 2007. These characteristics of TC genesis for fall in 2007 could be confirmed through analyzing various variables, such as a large-scale atmospheric circulation, outgoing longwave radiation (OLR), vertical zonal wind shear, and sea surface temperature (SST). On the other hand, a frequency of the TC that occurred to the north of 20°N showed a clear interdecadal variation and its decreasing trend was distinctive in recent years. Its intensity was also weaker that TCs that did to the south of 20°N. However, a latitude of TC genesis showed an increasing trend until recent years, whose variation was consistent with trend that through a SST analysis, warm SST went north in recent years.

Visions of ubiquitous robotics and ambient intelligence involve distributing information, knowledge, computation over a wide range of servers and data storage devices located all over the world, and integrating tiny microprocessors, actuators, and sensors into everyday objects as well in order to make them smart. In this paper, we introduce our ongoing research effort aimed at realizing ubiquitous robots in an information structured space. For this, a ubiquitous space and ambient intelligent systems for a librarian robot are introduced and the RFID technology based approach for these systems is described.
