Abstract: A central management server includes a determination module determining a landable local delivery hub among a plurality of local delivery hubs located within a preset radius centered around a destination, when a location information request for the landable local delivery hub is received from an unmanned cargo aircraft; and a control module configured to transmit a landing command including the location information of the determined landable local delivery hub to the unmanned cargo aircraft, and transmit a task execution command to cause the unmanned cargo aircraft to deliver goods to the destination. The determination module determines the landable local delivery hub, based on a combination of an expected landing standby period of the unmanned cargo aircraft, an expected battery consumption amount of the unmanned cargo aircraft, an expected delivery period of the unmanned delivery robot, and an expected battery consumption amount of the unmanned delivery robot.

Abstract: A delivery management server includes: a control module for searching for a plurality of delivery locations located on a navigation route among the navigation information and transmitting the searched delivery locations, when order information and navigation information of goods are received; and a determination module for determining an assembly point to receive goods loaded in an unmanned cargo aircraft according to the order information and an unmanned delivery robot to receive the goods from the assembly point and deliver them to the delivery location to receive the goods from the assembly point and deliver the same to the delivery location, so that the goods can be delivered to the delivery location within the estimated arrival time, when the delivery location selected by the user among the plurality of delivery locations and the estimated arrival time of the vehicle to the selected delivery location are received.

Abstract: An apparatus for loading and unloading cargo, capable of loading cargo while distributing the weight of the cargo and unloading the cargo regardless of the loading order of the cargo, is provided. The apparatus for loading and unloading cargo may include: a base portion; a rail installed on the base portion; a plurality of movable plates disposed on the rail, supporting the cargo, and moving along the rail; and a raising-lowering portion connected between the base portion and a body so that the base portion can be raised and lowered.

Abstract: The present invention relates to a hybrid catalyst composition comprising different transition metal compounds, to a catalyst for olefin polymerization comprising the same, and to processes for preparing the same. Specifically, the present invention relates to a hybrid catalyst composition comprising two or more types of transition metal compounds having a non-bridged biscyclopentadienyl group with different central metals, to a catalyst for olefin polymerization comprising the same, and processes for preparing the hybrid catalyst composition and the catalyst.

Abstract: A service robot for guiding and describing a displayed vehicle and a method for operating the robot, may include a projector for projecting visual information related to a target vehicle; monitoring means for monitoring a state of a user; and a controller configured to: suggest, to the user, presentation of visual information in conjunction with a guide description of the target vehicle; determine, via the monitoring means, whether the user has accepted the suggestion; and upon determination that the user has accepted the suggestion, present the visual information via the projector.

Abstract: A pair of detachable crutches extends in a longitudinal direction, where each of the detachable crutches includes a metal ball having magnetic properties and a holder having magnetic properties. A magnetic force is generated between the metal ball provided at one of the crutches and the holder provided at the other one of the crutches so as to maintain attachment therebetween. Each of the crutches further includes a sensor configured to sense whether the metal ball and the holder have been attached to each other.

Abstract: An apparatus for providing a vehicle sharing service, a system including the same, and a method thereof, may include setting a vehicle sharing service mode through a vehicle terminal or a user terminal to protect private information and provide a user customized vehicle sharing service.

Abstract: A charge management server and a method of controlling the same are provided. The method includes receiving a reservation time and reference usage fees of a first charger that is disposed in a first charging station from a first charging station server. The reservation time and real-time usage fees are transmitted to a first vehicle that generates a request for charging station information. In response to receiving a charging reservation request with respect to the first charger from the first vehicle, the reservation information is transmitted to the first vehicle. The real-time usage fees are determined as the sum of the reference usage fees and variable usage fees.

Abstract: An advertisement system using a vehicle and an advertisement method using the same are provided. The advertisement system includes an advertisement server that stores advertisement contents regarding a plurality of advertisers and at least one advertisement playback unit that is mounted to a vehicle and plays back the advertisement contents. An advertisement controller receives the advertisement contents from the advertisement server by communicating with the advertisement server and controls the received advertisement contents to be played back through the advertisement playback unit. When parking the vehicle, the advertisement contents supplied from the advertisement server are played back through the advertisement playback unit mounted to the vehicle.
