다중 클러스터 시스템을 위한 Co-Allcation 알고리즘

본 논문에서는 Grid 시스템에서 작업을 할당하기 위해서, 가능한 모든 작업 분할 방법을 찾는 기법에 대해 연구 하고자 한다. 즉 다수의 노드를 가진 여러 클러스터 사이에 많은 노드를 필요로 하는 작업을 할당하기 위해 변형된 깊이 우선 탐색 트리를 사용하여 작업 분할 리스트를 찾는 방법을 만들고, 그 알고리즘의 속도 및 효율을 평가하였다. 제안된 알고리즘은 전체 리스트를 검색하는 방법에 비해 속도 측면에서 빠른 효율을 보이는 것을 알 수 있다. 따라서 제안된 알고리즘은 동기화된 작업의 스케줄링에 사용할 경우 유용할 것으로 생각된다.

Cancer-preventive effects of ethanol extract of elm tree root (EEE) were investigated. In the in vitro cytotoxicity assay, colon cancer cells were incubated with a chloroform fraction of EEE (CF-EEE). CF-EEE significantly inhibited the proliferation of cells and induced apoptotic cell death in a dose-dependent manner. For the assessment of chemopreventive efficacy in vivo, male F344 rats were fed with EEE (0.5 or 1%) in diet for 8 weeks, and were subcutaneously injected with 1,2-dimethylhydrazine (DMH) to induce colonic aberrant crypt foci (ACF). EEE (0.5 and 1%) significantly decreased both the numbers of AC (1191.1/colon) and ACF (529.3/colon) induced by DMH. In addition, in the Western blot analysis on the colonic mucosa, administration of EEE triggered expression of caspase-3, a key factor of an apoptotic cascade. These results suggest that extract of elm tree root may have potential chemopreventive principles that lead to apoptosis of cancer cells, and thereby suppress colorectal carcinogenesis during the initiation stage.

The biggest obstacle in utilizing Telerobotics is that an exclusive line is necessary to connect the distant place and manipulator for the purpose of remote control Moreover, installment of an exclusive line is limited to relatively short distance, as the installment entails more difficulties with longer distance and increasing installment cost The purpose of this paper is to suggest a methodology of factory automation by using Lab VIEW to control and monitor actuators, which are the basis of controlling manipulators, form distant places
