  • Publication number: 20180268376
    Abstract: A facility management system and a method thereof using perspective definition metadata, and more specifically, to a facility management system and a method thereof using perspective definition metadata, in which a perspective definition metadata structure for interconnecting Building Information Modeling (BIM) and external Facility Management (FM) data considering variability and expandability from the perspective of a user is used to improve expandability of the system by extracting information required for the role of the user from diverse heterogeneous data sources so that management and reusability functions of the system can be maximized even after the system is developed.

  • Patent number: 8518530
    Abstract: The present invention relates to a production method for an ultra-low-dielectric-constant film, in which ratios are optimised in a mixed solution having a matrix consisting of a poly (alkyl silsesquioxane) copolymer and a porogen represented by Chemical formula 1, and in which this mixed solution is subjected to ultraviolet curing during a heat treatment. The ultra-low-dieletric-constant film of the present invention can be used as an intermediate insulating film for next generation semiconductors instead of the SiO2 dielectric films currently used, since pores of from 1 to 3 nm are uniformly distributed at from 10 to 30% and a very high degree of mechanical elasticity of from 10.5 to 19 GPa is achieved at a low dielectric constant from 2.12 to 2.4.

  • Publication number: 20070044147
    Abstract: A network monitoring apparatus collects packets of a first network, and generates visual information by displaying the packets on a parallel coordinate system which has one or more parallel axis for parameters of the packets. The network monitoring apparatus may extract attack packets from the packet, and the network monitoring apparatus may transmit the visual information to a remote server. Through the network monitoring apparatus, the network manager can visually grasp the state of the network or the existence of a network attack.
