Abstract: An apparatus and method of providing a contextual-information-based service are provided. The method includes acquiring information of at least one content posted through a first service based on information on activities of the first service of a user, transmitting the acquired information on the at least one content to a terminal, when any one of the information on the at least one content is selected by the terminal, generating at least one route information for arrival at a time of forming a similar environment to an environment when content corresponding to the selected content information is generated, based on contextual information of the content corresponding to the selected content information, and transmitting the generated at least one route information to the terminal.

Abstract: An autonomous driving control apparatus for controlling an autonomous vehicle to travel by avoiding a static object located on a driving path and a method thereof. The autonomous driving control apparatus may include a memory storing map data including road information, a sensor configured to detect an object, and a processor coupled to the memory and the sensor. The processor may be configured to determine, using the sensor, a static object located in an exit section of an intersection associated with a vehicle, determines a drivable area, based on a location of the static object and the road information included in the map data, determine, based on the drivable area, a driving path for the vehicle to avoid a collision with the static object, and control a movement of the vehicle along the driving path.

Abstract: A battery module includes a module housing, a gauge hole formed in the module housing, a plurality of battery cells in the module housing, a cell pressing plate accommodated in the module housing, and a swelling gauge provided to protrude from a surface of the cell pressing plate. The plurality of battery cells have a normal state and a swelling state. An end of the swelling gauge extends outside the module housing when the plurality of battery cells are in the normal state.

Abstract: A substrate treatment apparatus including a process chamber configured to process a wafer therein; a load lock chamber configured to accommodate the wafer and configured to switch between an atmospheric state and a vacuum state; and a load lock radical supply configured to supply radicals into the load lock chamber.

Abstract: A fronthaul multiplexer according to one aspect of the present invention combines uplink packets in a compressed state that is received from two or more radio units so that the uplink packets are accumulated and combined immediately when received or the uplink packets are recompressed using a compressing method with high compression efficiency when stored in a memory in order to reduce a use amount of memory.

Abstract: A method of combining compressed uplink signals according to one aspect of the present disclosure is a method of combining IQ data of uplink signals compressed without decompression by a block floating point compression method, a block scaling compression method, or a -law compression method.
