Abstract: A novel compound for a capping layer, and an organic light-emitting device containing the same are disclosed.

Abstract: Provided are a method and apparatus for providing a network switching service to a user equipment.

Abstract: Provided are a method and apparatus for a user equipment, a core network, and a second device to enable bidirectional communication for second devices. The method of the second device may include receiving internet protocol (IP) configuration information for automatically configuring an IP version 6 (IPv6) address of the second device from a core network through a user equipment; generating the IPv6 address using information in the IP configuration information; and transmitting the generated IPv6 address to the core network through the UE.

Abstract: A device for preventing slipping of a vehicle is disclosed, which improves a vehicle slipping prevention device in which a plurality of spikes connected with a connection member are inserted into a gap between double wheels disposed at a rear side of a large size vehicle at regular intervals for preventing slipping. In the present invention, a structure contacting with a tire surface along with a spike is newly improved, and a structure of an engaging member used for maintaining the tensional force of a plurality of spikes connected by means of a connection member is newly improved. It is possible to achieve a fast and simple engaging and disengaging work and to keep a substantial tensional force so that a vehicle slipping prevention device is not disengaged even during a long time drive of a vehicle.

Abstract: A device for preventing slipping of a vehicle is disclosed. The device of the present invention includes spikes (10) which are inserted between tires of a double wheel, a connection member (20) which couples the spikes to each other, and a fastener (50) which are provided on the opposite ends of the connection member. The fastener includes a catch (30) which is connected to a first end of the connection member, and a clamp (40) which is connected to a second end of the connection, and to which the catch is locked. When the catch is locked to the clamp to attach the device to the tires, the catch is disposed inside the connection member, that is, in a space between the tires, thus preventing the catch from coming into contact with a road surface when the vehicle travels.
