Abstract: The present disclosure relates to a plurality of host materials, an organic electroluminescent compound, and an organic electroluminescent device comprising the same. By comprising a specific combination of host compounds and/or an organic electroluminescent compound according to the present disclosure as an organic electroluminescent material, an organic electroluminescent device having low driving voltage and/or high luminous efficiency and/or long lifespan characteristics can be provided.

Abstract: The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure, it is possible to produce an organic electroluminescent device having improved driving voltage, power efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

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

Abstract: The present disclosure relates to an antimicrobial peptide analog derived from abalone and an antimicrobial pharmaceutical composition containing the same. The antimicrobial peptide analog according to the present disclosure is designed based on hdMolluscidin which is a peptide derived from the gill of abalone and has been designed to be commercially viable by reducing the number of amino acids. Despite the reduced number of amino acids, the designed peptide analog exhibits very superior antimicrobial activity as well as high membrane permeability and low hemolytic activity.
