Abstract: Disclosed herein are a method and apparatus for converting a credential data schema.

Abstract: Disclosed herein is a method for user-centered visitor access management, which may include issuing, by a management office server, a digital certificate to a householder terminal; registering, by a wall-pad, a householder in response to a request to register the householder based on the digital certificate; requesting, by the householder terminal, the management office server to register a visitor based on a visit request from a visitor terminal and delegating the digital certificate to the visitor terminal; making an entry request to a management terminal based on the digital certificate; verifying, by the wall-pad, the digital certificate based on a request for verification for entry from a wall-pad management terminal and providing a verification result to the wall-pad management terminal when the management terminal is the wall-pad management terminal; and managing and controlling, by the wall-pad, permission to use home devices based on delegated permission information of the digital certificate.

Abstract: The present disclosure provides a mobile communications system line number sheet management device and method. Provided, according to one aspect of the present disclosure, is a line number sheet management device and method, for automating access network-related line number sheet management by automatically collecting and updating line number information, the line number information being collected from a mobile communications base station management server (mobile communications system management server) and a fronthaul management server. Provided, according to another aspect of the present disclosure, is a fronthaul device for: acquiring unique information of a base station by receiving an optical signal from any one of a radio unit (RU) and a digital unit (DU); and transmitting the unique information of the base station to a fronthaul management server.

Abstract: A pellicle for extreme ultraviolet (EUV) lithography is based on yttrium carbide and used in a EUV lithography process. The pellicle for EUV lithography includes a pellicle layer that has a core layer containing yttrium carbide. The yttrium carbide is YCx in which the atomic percentage of carbon is within a range of 25% to 45%.

Abstract: Disclosed is a cosmetic composition having a double-shell type nano-structure. More particularly, the nano-structure of the cosmetic composition includes: a water-soluble bioactive ingredient core; a core shell containing poly(ethyleneglycol)-poly(caprolactone)-poly(ethyleneglycol) (PE-PCL-PEG) triblock copolymer in order to include the bioactive ingredient core therein; and an outer shell containing phospholipids or derivatives thereof in order to enclose the core shell therein. Such a cosmetic composition improves stability of active components which are prone to oxidation, light degradation, heat degradation, etc., is formed in a nanoparticle size which in turn shows high transdermal absorption and is very useful to prepare a cosmetic composition stably encapsulating various bioactive ingredients with anti-wrinkle effects, whitening effects, and so forth.
