Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.

Abstract: The present disclosure provides a seat cushion extension device for a fold-and-dive seat. The seat cushion extension device may include a pair of seat cushion side frames arranged at a predetermined interval, a seatback frame rotatably connected to the pair of seat cushion side frames and having a guide pin formed on an outer surface thereof, a seat cushion frame, a pair of links rotatably connected between the pair of seat cushion side frames and a front end of the seat cushion frame, and a pair of extension frames. Each of the pair of extension frames may have a front end connected to the seat cushion frame, and a rear end formed with a guide hole, into which a guide pin may be inserted. The seat cushion extension device may facilitate a forward extension of a seat cushion regardless of a position of a seatback of the fold-and-dive seat.

Abstract: The present disclosure relates to a technical virtual sensing idea of indirectly measuring structural vibration information on an unmeasured point while minimizing the number of sensors attached for actual measurement, and more particularly, to a technique of estimating measurement data of an unmeasured point using a finite element model, synchronized and updated based on experimental data of an actual measurement subject structure, and a virtual sensing algorithm.

Abstract: A method and apparatus for providing a help guide are provided. The method and apparatus for providing a help guide by an electronic device includes acquiring an image by using a camera, detecting a face from the image, and providing a help guide corresponding to the task being executed, when a user's input is not received with respect to a task being executed while the face is being detected and a predetermined help guide providing condition is satisfied.
