Abstract: The disclosure relates to a wireless communication system, in which a method performed by a user equipment includes receiving, from a base station, information configuring a plurality of sounding reference signal (SRS) resources that are related with one channel state information-reference signal (CSI-RS) resource, receiving an SRS resource indicator (SRI) indicating at least one SRS resource from among the plurality of SRS resources, obtaining, based on an implicit precoding being indicated for an uplink channel, precoding information for the uplink channel based on the CSI-RS resource related with a most recently transmitted SRS of the at least one SRS resource indicated by the SRI, and transmitting, to the base station, the uplink channel based on the precoding information.

Abstract: In the case of a gas in which several gases are mixed, a type and concentration of the gas may be incorrectly measured when measured using only an optical band-pass filter. The invention of the present application is directed to providing a technology in which a plurality of broadband band-pass filters having overlapping regions are provided to calculate a magnitude of absorption for each wavelength band for light passing through each broadband band-pass filter, thereby identifying the presence of a gas of interest and the presence of a gas other than the gas of interest.

Abstract: The present invention relates to an electronic vote system and method which integrally administrates and operates various vote methods by using the electronic vote, and at the same time, performs a mirroring backup synchronization, and the present invention integrally administrates and operates, by using the electronic vote, various vote methods such as an electronic vote using a separate vote terminal, or a mobile electronic vote using voter terminal, or an on-line electronic vote through the Internet using the voter terminal, and at the same time, performs a mirroring backup synchronization with the electronic vote provision server through the mirroring backup server.

Abstract: An apparatus for earthquake evacuation and rescue comprises a sensor module that senses occurrence of earthquake, a lighting module that provides visibility, a communication module that supplies information, a power supply module that provides electric power to the apparatus, a display module, a location transmitter module that transmits signal for location of the apparatus, a GPS module that obtains location data for the apparatus, an actuator module that is adapted to be linked to a gas line and an electric power line of a housing, and a control module that controls the operation of the other modules. The control module turns on the lighting module when the control module determines that an earthquake of predetermined level occurred.
