Abstract: The present invention relates to a 4-gingerol derivative compound, or a racemate, isomer, or pharmaceutically acceptable salt thereof, the compound being capable of inhibiting biofilm formation and production of virulence factors. The 4-gingerol derivative compound according to the present invention has binding affinity to RhlR and corresponding RhlR antagonism activity that are significantly improved, and therefore can effectively inhibit biofilm formation and production of virulence factors. Furthermore, various bacterial infectious diseases caused by biofilms can be fundamentally prevented or treated by using a pharmaceutical composition comprising the 4-gingerol derivative compound, or a racemate, isomer, or pharmaceutically acceptable salt thereof as an active ingredient.

Abstract: The present disclosure relates to creating a map by identifying a moving object, and a robot implementing the method, and the method comprises, by a sensing unit of a robot, sensing a first object located outside the robot, by a control unit of the robot, calculating mobility of the sensed first object, and storing sensed information and sensed time information of the first object in a map, as a fixed object, when the mobility of the first object calculated by the control unit of the robot is lower than a preset reference.

Abstract: The present disclosure relates to a method of identifying a functional region in a 3-dimensional space and a robot implementing the method, and the robot comprises a sensing module that senses a protrusion located outside a robot and provides height and depth information of the sensed protrusion; a functional unit that provides a predetermined function to the outside; a moving unit that moves the robot; a map storage unit that stores a map required for movement of the robot; and a control unit that controls these components.
