Abstract: Methods of manufacturing a semiconductor device are provided. The methods may include forming a fin-type active region protruding from a substrate and forming a gate insulating film covering a top surface and both sidewalls of the fin-type active region. The gate insulating film may include a high-k dielectric film. The methods may also include forming a metal-containing layer on the gate insulating film, forming a silicon capping layer containing hydrogen atoms on the metal-containing layer, removing a portion of the hydrogen atoms contained in the silicon capping layer, removing the silicon capping layer and at least a portion of the metal-containing layer, and forming a gate electrode on the gate insulating film. The gate electrode may cover the top surface and the both sidewalls of the fin-type active region.

Abstract: The present disclosure relates to an organic electroluminescent compound of Formula 1 (variables R1-R10 defined herein), and an organic electroluminescent device comprising the same. By using the organic electroluminescent compound according to the present disclosure, it is possible to produce an organic electroluminescent device which can be operated at a lowered driving voltage, shows excellence in luminous efficiency such as current efficiency and power efficiency, and has high color purity and improved lifespan.

Abstract: Disclosed is a method for reselling contents registered in contents selling apparatus by a content reselling apparatus. The method includes: accessing the content selling apparatus based on reseller information of the content reselling apparatus; selecting at least one reselling content in which reselling is allowed from contents registered in the content selling apparatus; receiving and notifying information of the selected reselling content; receiving reselling content information which is requested to be purchased from a user terminal among the notified reselling contents; and transferring purchase request information of the to user terminal to the content selling apparatus.

Abstract: A communication signal processing apparatus for a repeater includes an interface for receiving the communication signals of at least two different communication services, and a communication signal processor for combining a pair of different communication signals into a single digital signal, converting the single digital signal into a frame and serializing the frame.

Abstract: A cascade-type multiplex radio communication relay system, in which a donor and a Main Hub Unit (MHU) are connected to each other through an Unshielded Twisted Pair (UTP) cable to enable duplex communication, and in which a plurality of remote units are connected to the MHU through UTP cables to enable duplex communication. The cascade-type multiplex radio communication relay system adopts a method of converting at least two different RF communication signals into a single UTP transmission frame, and relaying the UTP transmission frame through a UTP cable in a digital communication manner.
