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: An electronic device includes a display device, which may be fabricated using a described method. The display device includes a glass substrate including a first surface, a second surface opposite the first surface, and a side surface between the first surface and the second surface, an outermost structure on the first surface of the glass substrate and located adjacent to an edge of one side of the glass substrate, and a display area including a plurality of light emitting areas on the first surface of the glass substrate and located farther from the edge of the one side of the glass substrate than the outermost structure is. A minimum distance from the side surface of the glass substrate to the outermost structure is equal to 130 ?m or less.

Abstract: An apparatus for generating a multi-view face descriptor includes a multi-view face database storing sets of training face images and sets of test face images, each set including a mosaic view of a single identity; a basis matrix generator generating a basis matrix of the training face images shown from respective viewpoints searched from the multi-view face database; a feature extractor extracting feature vectors of a test face image shown from each viewpoint using the basis matrix of the training face images searched from the multi-view face database; a to-be-registered view selector searching the test face images using the feature vectors extracted by the feature extractor and selecting a plurality of viewpoints as registered viewpoints according to the search results; and a face descriptor generator generating a multi-view face descriptor by synthesizing face descriptors having the plurality of selected viewpoints.
