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 relates to a method of providing a proximal user networking service by means of a near-field communication network and a system therefor. Specifically, the present disclosure implements an environment in which, when an ad packet is broadcast using a certain host device, a guest device that receives the ad packet in the vicinity uploads relevant information to a service server, thereby allowing the host device to check guest devices that have been present in proximity thereto in the vicinity.

Abstract: Disclosed herein are a reasoning method based on a structural attention mechanism for knowledge-based question answering and a computing apparatus for performing the reasoning method. The reasoning method includes: recognizing one or more entities in a query including content and a question, and linking the recognized entities to a knowledge base; constructing a question hypergraph and a query-aware knowledge hypergraph by performing a multi-hop graph walk on a question graph and the knowledge base; and inferring a correct answer to the question by applying as attention mechanism to a query hyperedge and a knowledge hyperedge included in the question hypergraph and the query-aware knowledge hypergraph, respectively.
