Abstract: The present embodiment relates to a touch sensing apparatus and a touch sensing method and, more specifically, to a touch sensing apparatus and a touch sensing method, which rapidly and accurately separate a multi-touch in which touch areas are adjacent to each other.

Abstract: Disclosed may be a method for evaluating valet mode driving of a vehicle. The method includes determining whether or not a valet mode entry condition may be satisfied, determining a plurality of driving evaluation factors for valet parking based on at least one of a vehicle status or a driving environment, upon determining that the valet mode entry condition may be satisfied, calculating a valet driving evaluation score by analyzing the determined driving evaluation factors and collecting result values acquired through analysis, and displaying the calculated valet driving evaluation score.

Abstract: Provided is an organic compound which contributes to substantial improvements in the luminous efficiency and viewing angle of an organic electroluminescent device. An organic electroluminescent device includes: a first electrode; a second electrode; an organic layer disposed between the first electrode and the second electrode; and a capping layer. The organic layer or the capping layer includes an organic compound represented by chemical formula 1.

Abstract: Disclosed is an organic compound contributing to improving the substantial light efficiency and field of view of an organic electroluminescent device.

Abstract: Provided is a tertiary amine derivative. The tertiary amine derivative effectively absorbs light in the UV region from high-energy external light sources to minimize damage to organic materials in organic electroluminescent devices, contributing to a substantial improvement in the lifetime of the organic electroluminescent devices.

Abstract: A network security system according to an embodiment may include: a DNS blocking server that is connected to network equipment to which a client terminal is connected and mirrors a DNS query packet going through the network equipment, and that generates and transmits a fake DNS response packet to the client terminal if a DNS query domain address of the DNS query packet is a domain address to be managed; and a proxy server that monitors a request packet from the client terminal generated using the fake DNS response packet.
