Abstract: Provided is an outer covering material for a vacuum heat insulation material, the outer covering material having a laminated structure which sequentially, from the top, comprises: a protecting layer; a barrier layer; and a sealing material, wherein the barrier layer comprises: a polyethylene terephthalate (PET) resin film on which an aluminum oxide film is deposited; and an ethylene vinyl alcohol (EVOH) resin film on which a metal thin film is deposited. Provided is a vacuum heat insulation material, comprising: a core material consisting of glass fibers; and the outer covering material which houses the core material and decompresses the inner portion thereof.

Abstract: Disclosed are a method for SDN based network management and an apparatus performing the same. A method for network management, performed in a central control apparatus, may comprise receiving a path request message indicating a request to configure a path from a terminal; generating path list information including information about at least one configurable path, and providing the terminal with the path list information; receiving information about a specific path selected in the path list information from the terminal; and transmitting information about at least one detail function included in each of at least one node constituting the selected specific path to the terminal. Therefore, a path optimized for user's requirements may be easily configured, and so service quality may be enhanced.

Abstract: A wireless access point apparatus for configuring a multiple data security tunnel, and a system having the same and a method thereof, and more particularly, a technology associated with a wireless access point apparatus that supports a wireless secure throughout all layers in a wireless network section. The wireless access point apparatus for configuring a multiple data security tunnel includes: a control security tunnel managing unit managing a control security tunnel that transfers policies and authentication information for wireless network access control and management; and a multiple data security tunnel managing unit creating a data security tunnel for each of a plurality of wireless terminals, while, creating and managing the multiple data security tunnel for each of application services of the plurality of wireless terminals.

Abstract: The present invention relates to a glass fiberboard and to a production method therefor, and more specifically, to technology for providing a glass fiberboard for vacuum heat insulation and a production method therefor, which have outstanding initial heat insulation performance and economic advantages through application of an optimized inorganic binder.

Abstract: A vacuum insulation panel includes a core, and an outer skin material for surrounding the core, wherein the outer skin material includes a bending portion formed at one side surface thereof and sealing portions formed at three side surfaces thereof. A method for manufacturing a vacuum insulation panel includes preparing an outer skin material envelope by forming sealing portions at two side surfaces of an outer skin material including a bending portion formed at one side surface thereof, inserting a core into the outer skin material envelope, decompressing the inside of the outer skin material envelope, and forming a sealing portion at one side surface of the outer skin material envelope.
