By comprising specific combinations of compounds according to the present disclosure as the plurality of host materials or by comprising a compound according to the present disclosure, it is possible to provide organic electroluminescent devices having improved lifespan characteristics compared to conventional organic electroluminescent devices.

Abstract: Disclosed herein are an apparatus and method for automatic parking based on recognition of a parking area environment. The method may include searching for an available parking space, determining whether reverse parking is possible by recognizing the environment of the available parking space, recognizing at least one additional vehicle located in the vicinity of the available parking space, and setting a parking destination based on the determination of whether reverse parking is possible and the result of recognition of the at least one additional vehicle.

Abstract: The present invention relates to an organic electroluminescent device comprising at least one light-emitting layer between an anode and a cathode, wherein the light-emitting layer comprises a host and a phosphorescent dopant; the host comprises plural host compounds; at least a first host compound of the plural host compounds has a structure of a nitrogen-containing heterocyclic linker bonded to a nitrogen atom of a carbazole of an indole-carbazole, indene-carbazole, benzofuran-carbazole, or benzothiophene-carbazole residue; and a second host compound has a carbazole-aryl-carbazole or carbazole-carbazole structure. According to the present invention, by using a specific multi-component host different from the conventional organic electroluminescent device, an organic electroluminescent device of significantly improved lifespan is provided.

Abstract: The present disclosure relates to a plurality of host materials, an organic electroluminescent compound, and an organic electroluminescent device comprising the same. An organic electroluminescent device having improved driving voltage, luminous efficiency, and/or lifespan properties compared to a conventional organic electroluminescent device can be provided by including the specific combination of compounds according to the present disclosure as a plurality of host materials or by including the compound according to the present disclosure.

Abstract: The present disclosure relates to a plurality of host materials comprising a first host material comprising at least one compound represented by formula 1 and a second host material comprising at least one compound represented by formula 2, and an organic electroluminescent device comprising the same. An organic electroluminescent device having significantly improved lifetime properties is provided by comprising a specific combination of compounds according to the present disclosure as host materials.

Abstract: A security protocol structure for a Wireless Application Protocol (WAP) standard structure is disclosed. The security protocol structure provides a data security function in an application layer by providing a secret session having a secured session layer security (SSLS) protocol for providing a secret session interface to an application program between the session layer and the application layer.

Abstract: A method of providing wireless Internet service in a gateway system having a conversation function according to short messages includes storing and managing the latest URL web contents in a URL memory using the TTL, expire time and last modification time for URL web contents. Web contents corresponding to URL information requested by a mobile terminal are parsed and stored in a cache, and then transmitted to the mobile terminal through I-SMSC. The service method stores and manages the latest URL web contents in the URL memory using the TTL, expire time and last modification time for URL web contents to directly access the Internet. Thus, the service method provides the URL web contents to the mobile terminal when there is a request for URL information from a mobile terminal supporting no WAP standard for URL information which does not exist in the URL memory.
