Exercise capacity is a valuable trait in horses, and it has been used as a horse selection criterion. Although exercise affects molecular homeostasis and adaptation in horses, the mechanisms underlying these effects are not fully described. This study was carried out to identify changes in the blood profiles of microRNAs (miRNAs) and mRNAs induced by exercise in horse leukocytes. Total RNAs isolated from the peripheral blood leukocytes of four Warmblood horses before and after exercise were... -

Stems and pods of hyacinth bean cultivated in a farmer’s field in Gazipur District, Bangladesh, were found rotted in nearly 5% hyacinth bean plants. A fungus having fluffy mycelium and large sclerotia was isolated from affected tissues. Combined results of morphological, molecular and pathological analyses identified the fungus as Sclerotinia sclerotiorum (Lib) de Bary. Inoculating the fungus on healthy hyacinth bean plants and pods reproduced the symptoms previously observed in the field. The... -

Maintenance of a beneficial microbial community, especially in the rhizosphere, is indispensable for plant growth and agricultural sustainability. In this sense, plant growth-promoting rhizobacteria (PGPR) have been extensively studied for their role in plant growth promotion and disease resistance. However, the impact of introducing PGPR strains into rhizosphere microbial communities is still underexplored. We previously found that the Proteus vulgaris JBLS202 strain (JBLS202) promoted growth... -

a typical PVY isolate. Phylogenetic analysis indicated that this isolate belongs to the N-Wi strain group of PVY recombinants (PVYN-Wi) and also shared the highest overall sequence identity (nucleotide and amino acid) with other members of this strain group. However, recombination analysis of isolate HLJ-C-44 revealed a recombination pattern that differed from that of other PVYN-Wi isolates. Moreover, biological assays in four different potato cultivars and in Nicotiana tabacum also revealed a... -

is a major factor in the cloud computing environment which has many benefits in terms of low cost and accessibility of data, as users often store sensitive information with cloud storage providers, unaware that these providers may be compromised. Dealing with “single cloud” providers is predicted to become less popular with customers due to risks of service availability failure and the possibility of malicious insiders in the single cloud. A movement towards “multi-clouds” or in other words,... -

New Paradigm and its Policy Framework in Decision-making on Large Dams
한국습지학회 한국습지학회지 2006, Vol.8 No.1 5 97-106 (10 pages)
This study discusses two canceled dam projects, Youngwol Dam in South Korea and Two Forks Dam in Colorado of the United States. Both of them illustrate how the new paradigm applies to regional water projects because they became victims of environmental opposition in the new paradigm. While the cases have no apparent close relationships and they occurred in different decades, they offer interesting comparisons. They were basically struggles between water development coalitions and environmental... -

there was a significant improvement in social efficacy overall, and in systems thinking, there was a significant improvement in mental model, personal mastery, systems thinking, shared vision, and overall. It was found that applying artificial intelligence education to information-gifted students can have advantages. It is hoped that the paper will contribute to the expansion of artificial intelligence education for information-gifted students who will be the main players in the future. -

본 논문에서는 무선 인터넷 프록시 서버 클러스터를 사용하여 무선 인터넷의 문제와 요구들을 캐싱(Caching), 압축(Distillation) 및 클러스터(Clustering)를 통하여 해결하려고 한다. 무선 인터넷 프록시 서버 클러스터에서 고려되어야 하는 것은 시스템적인 확장성, 단순한 구조, 캐시간 협동성(Cooperative Caching), Hot Spot에 대한 처리 등이다. 본 연구자들은 기존 연구에서 시스템적인 확장성과 단순한 구조를 가지는 CD-A라는 구조를 제안하였으나 캐시간 협동성이 없다는 단점을 가진다. 이의 개선된 구조로 해쉬를 이용하여... -

저장 시스템에 대한 사용자 요구가 증가하고 있다. 네트워크 연결형 자료 저장 시스템인 SAN(Storage Area Network)은 호스트와 디스크를 광채널 스위치로 연결하는 구조로서 저장 공간과 서버에 대한 확장성을 제공한다. SAN 환경에서는 다수의 호스트가 네트워크에 연결된 저장 장치를 공유하므로 공유 데이타에 대한 일관성 유지가 필요하다. 이를 위해 각 호스트가 수정한 데이타를 즉시 디스크에 반영하는 방법을 사용하고 있지만 이는 느린 디스크 접근 시간(Disk Access Time)으로 인해 시스템의 성능을 저하시키는 요인이 된다.... -

처리과정이 필요하다. 본 연구에서는 DTD가 있는 XML 문서의 관계 데이터베이스 저장을 다루고 있다. 기존의 Shared Inlining 방법과 Hybrid Inlining 방법을 보완한 릴레이션의 단편과 과도한 조인 연산을 줄여주는 Association Inlining 방법을 제안하고 실제 실험을 통하여 성능이 개선되었음을 보인다. DTD를 단순화시켜 이로부터 저장구조 정보를 추출하고 관계 데이터베이스의 저장구조로 사상시키기 위하여 기존의 맵 클래스를 확장하였다. XML 문서의 분석을 통하여 다중값 엘리먼트, 여러 개의 상위 엘리먼트를 갖는 엘리먼트,... -

이에 대한 장기적이고 체계적인 방안을 모색하려는 노력이 이루어 진 바 있다. 특히 인쇄본저널의 경우 디지털저널의 등장이후 지속적인 이용률 감소와 도서관의 공간 부족 문제로 이어지면서 인쇄본저널의 새로운 보존 및 영구적인 아카이빙 구축에 대한 필요성이 대두되었다. 본 연구에서는 디지털시대의 인쇄본저널 아카이빙 관리 전략에 대한 선행연구 및 북미를 중심으로 진행된 웨스트 공동보존협약(WEST, Western Regional Storage) 프로젝트 사례를 고찰하고 분석함으로써 인쇄본저널의 보존에 대한 새로운 관리방안 및 향후... -

Dear fellow symposium participants -- I am very grateful for this opportunity to introduce to you some observations and information on the open-air museums in Sweden. I hope this will be of interest in an international perspective, as well as for my Korean colleagues whom I understand are actively engaged in expanding the role and the enormous potential of open-air museums here in Korea -- clearly a very worthwile endeavor. As the director of the Museum of Far Eastern Antiquities, I cannot claim...
