Abstract: The present disclosure relates to an apparatus and a method for processing road situation data. A road situation data processing method according to an exemplary embodiment of the present disclosure is a road situation data processing method which is performed by a processor of an apparatus for processing road situation data including: collecting sensing data on objects on a road from a plurality of sensors provided on the road; modeling a relationship between the objects on a graph based on sensing data on the objects; constructing a grid-based spatial index with respect to the graph modeling result; removing redundant sensing data among sensing data on the objects included in the grid-based spatial index; extracting an object corresponding to a response to a query by performing a predetermined query on the objects from which the redundant sensing data is removed; and outputting context awareness data to the object corresponding to the response to the query.

Abstract: A method and device are disclosed for channel connection in a wireless communication system supporting multiple links. An operation method for the device comprises the steps of: performing a first back-off operation in a first link among multiple links; stopping the first back-off operation when the first link is determined to be in a busy state due to the first back-off operation; and using a new back-off counter value to perform a second back-off operation in a second link among the multiple links when the second link is in an idle state in a preset period prior to the point in time at which the first back-off operation is stopped.

Abstract: Disclosed is a method of producing an olefin using a circulating fluidized bed process, including: (a) supplying a hydrocarbon mixture including propane and a dehydrogenation catalyst to a riser which is in a state of a fast fluidization regime, and thus inducing a dehydrogenation reaction; (b) separating an effluent from the dehydrogenation reaction into the catalyst and a propylene mixture; (c) stripping, in which a residual hydrocarbon compound is removed from the catalyst separated in step (b); (d) mixing the catalyst stripped in step (c) with a gas containing oxygen and thus continuously regenerating the catalyst; (e) circulating the catalyst regenerated in step (d) to step (a) and thus resupplying the catalyst to the riser; and (f) cooling, compressing, and separating the propylene mixture, which is a reaction product separated in step (b), and thus producing a propylene product.

Abstract: Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.

Abstract: Disclosed are a metal-nanoparticle-based liver-specific nucleic acid delivery system, a method of manufacturing the same, and a liver disease treatment composition containing the same. The liver-specific nucleic acid delivery system is coated with a bile acid-glycol chitosan polymer, so that it provides excellent liver-tissue specificity and high absorbance through digestive canals. Since the nucleic acid of the nucleic acid delivery system is coated with the bile acid-glycol chitosan polymer, it can be protected from decomposition of enzymes and the like inside a living organism. The liver-specific nucleic acid delivery system can be developed as an oral-administrating liver-disease treatment.
