Abstract: Disclosed is an apparatus for monitoring bioaerosols, including a capturer configured to capture bioaerosol particles in air in a capture solution; a particle sprayer configured to electro-spray the capture solution in a form of droplets such that the particles are included in at least some of the sprayed droplets; and an analyzer configured to analyze the particles, sprayed through the particle sprayer, by machine learning. In accordance with such a configuration, the droplets containing a certain amount of the particles can be continuously analyzed in real time by machine learning, thereby contributing to the improvement of monitoring efficiency for a specific bioaerosol genus.

Abstract: A self-propelled robot for performing jobs while travelling along a route, and more particularly to a mobile robot for correcting a position error generated in the course of movement of the robot to movably control the robot to a targeted area, including a control unit; a driving unit for moving the robot according to control of the control unit; an infrared signal transmitting/receiving unit for transmitting and/or receiving an infrared signal during travel of the robot according to the driving unit; a position correcting unit for receiving the infrared signal from the infrared signal transmitting/receiving unit to output an intrinsic code signal to the infrared signal transmitting/receiving unit, so that a position error data generated during the travel of the robot can be corrected by a predetermined position coordinate data; and a distance detecting unit for detecting a separated distance from the position correction unit to output a separted distance data detected therefrom to the control unit, so that t

Abstract: A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
