  • Publication number: 20140377773
    Abstract: The present invention relates to specific markers capable of detecting the development of colorectal cancer and the colorectal cancer inhibitory effect of SeMet (selenomethionine) having a chemopreventive effect against colorectal cancer. When the expressions of the biomarkers according to the present invention are measured and the expression levels thereof are analyzed in combination, whether SeMet (selenomethionine) is to be administered to prevent colorectal cancer can be determined and the development of colorectal cancer and the inhibitory effect of SeMet (selenomethionine) against the development of colorectal cancer can be monitored. Thus, these markers can be effectively used to observe the colorectal cancer inhibitory effect of SeMet (selenomethionine) and the prognosis of colorectal cancer resulting from the intake of SeMet (selenomethionine).

  • Patent number: 8811560
    Abstract: A system and a method of transforming a gain and an integral time constant of a proportional-integral (PI) controller according to a timer lapse time to relieve an excessive phenomenon of a steam generator level caused by rapid changes in open degrees of a downcomer feed-water valve and an economizer feed-water valve when reactor power transfers between low and high power sections. Accordingly, an excessive phenomenon of a steam generator level is relieved at a transfer time when reactor power transfers between low and high power sections. Therefore, a possibility of a stop of a reactor caused by the excessive phenomenon of the steam generator level is reduced to relieve burden on an operator and improve an operation rate and economic feasibility of a nuclear power plant.

  • Patent number: 8555058
    Abstract: A method of distributing group identifiers IDs (GIDs) in a power line communication (PLC) network, a method of receiving the GIDs, an authentication apparatus, and a PLC apparatus are provided. The authentication apparatus includes: an authentication mode storing unit which stores an authentication mode having a value including one of an authentication authorized mode and an authentication unauthorized mode; a GID request receiver which receives a GID request message from a PLC apparatus; and a GID transmitter which, if the authentication mode is the authentication authorized mode, transmits a GID corresponding to the PLC apparatus to the PLC apparatus. Authentication is realized in a PLC media access control layer distributing the GIDs between a PLC apparatus and an authentication apparatus, so manually inputting a GID into the PLC apparatus is not necessary. Further, the GIDs are distributed via the authentication apparatus, thereby centrally managing the GIDs.

  • Patent number: 8406298
    Abstract: A method and apparatus to efficiently transmit data. The method and apparatus effectively aggregate data and transmit the data in a high-speed power line communication (PLC) network. The method of transmitting the data includes combining each of at least one or more data units transferred from an upper layer, with a field to indicate attribute information of the data unit, dividing the combined data units and fields into frame blocks of an identical size, and aggregating the divided frame blocks and transferring the aggregated frame blocks as one frame to a PHY layer. In this way, data units of a variety of types and sizes transferred from the upper layer are aggregated and transmitted as the one frame.
