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 invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract: Various embodiments provide a method and an apparatus that comprises a memory, a display and a processor that is functionally connected to the memory or the display, wherein the processor is configured, when a user input for selecting a menu item is detected while an execution screen of an application is displayed on the display, to confirm display ratio configuration information, stored in the memory, of the application, to display a button for altering a display ratio of the application onto an application card on a list of applications that have recently been executed based on the confirmed display ratio configuration information, and to alter a display ratio of the application according to a selection of the displayed button. In addition, other embodiments are possible.
