Abstract: Disclosed herein is an apparatus for managing disaggregated memory, which is located in a virtual machine in a physical node. The apparatus is configured to select, depending on the proportion of valid pages, direct transfer between remote memory units or indirect transfer via local memory for each of the memory pages of the source remote memory to be migrated, among at least one remote memory unit used by the virtual machine, to transfer the memory pages of the source remote memory to target remote memory based on the direct transfer or the indirect transfer, and to release the source remote memory.

Abstract: The present invention relates to a method of coating the surface of inorganic powder particles with a silicon-carbon composite and to inorganic powder particles coated by the method. More specifically, the invention relates to a method of coating the surface of inorganic powder particles with a silicon-carbon composite by mixing inorganic powder particles with a solid organic silicon polymer and heating the mixture, and to inorganic powder particles coated by the method.

Abstract: The present invention relates to a visible light-responsive photocatalyst with an excellent removal efficiency of environmental contaminants, and a method of preparing the same. According to the present invention, the TiO2 surface having an increased visible light absorbance due to nitrogen-doping has been modified into a hydrophilic surface using polydimethylsiloxane (PDMS), i.e., a silicon-carbon precursor, and thereby significantly improved the removal efficiency of environmental contaminants under visible light. Additionally, the photocatalyst of the present invention for removing environmental contaminants is applicable to environment-friendly fields such as removal of volatile organic compounds, air purification, wastewater treatment and sterilization, and enables to remove contaminants by being attached to the surfaces of external walls of buildings, construction materials, glass windows, sound-absorbing walls, road facilities, signboards, etc., while preventing damages by sunlight.
