Abstract: The present invention relates to a novel 4-carbonylamino-4-phenylpyrimidine compound or a pharmaceutically acceptable salt thereof. Specifically, the present invention relates to a novel 4-carbonylamino-4-phenylpyrimidine compound or a pharmaceutically acceptable salt thereof, which exhibits GDH activity and as such, is effective for prevention or treatment of obesity, diabetes, or fatty liver.

Abstract: A seat adjustment apparatus for a vehicle includes a plurality of connection frames provided along two opposite sides of a seat frame and two opposite sides of a back frame and configured to move forward or rearward depending on a folding direction of the back frame, guide parts provided at middle points of the plurality of connection frames and configured to be moved upward or downward by forward or rearward movements of the connection frames, and a seat cushion pipe provided inside the two connection frames and configured such that front ends of the seat cushion pipe are connected to the guide parts, and a position of a rear end of the seat cushion pipe is adjusted upward or downward by upward or downward movements of the guide parts.

Abstract: A general-purpose audio connector is provided. The audio connector includes an earphone plug that includes a plurality of first terminals, and an earphone connector that includes a plurality of second terminals. The earphone plug is configured to be inserted into and to connect to the earphone connector. The number of poles of the plurality of first terminals that connect to the plurality of second terminals is variable depending on a movement of the earphone plug.

Abstract: An audio output device controls the application of active noise cancellation (ANC) levels based on a current status of the device. The audio output device includes a communication interface configured to provide a wired or wireless connection to a playback device, a signal detector configured to detect an audio signal provided through the communication interface, an ANC module configured to apply a first-level ANC to the audio signal, and a control unit configured to determine a level of the ANC to be applied by the ANC module. Upon determining that the audio signal is not provided based on information provided from at least one of the communication interface or the signal detector, the control unit instructs the ANC module to perform a second-level ANC.
