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: Provided are a communication terminal operable as a server and a method for processing a request therein. The communication terminal comprises a user input unit, a storage unit, a communication unit, and a control unit. The user input unit receives a user input. The storage unit stores software storing software necessary to process a request from a client terminal. The communication unit receives the request from the client terminal connected to a relay server, and sends data through the relay server in response to the request. The control unit receives the request from the client terminal, processes the request, and controls the communication unit according to the user input or the software stored in the storage unit. Here, the communication terminal is connected to the client server via a gateway server converting a private IP address into a certified IP address and the relay server having a common IP address and forwarding data.

Abstract: Provided are a remotely controllable communication terminal and a method for processing a request thereof. The remotely controllable communication terminal comprises a user input unit, a storage unit, a communication unit, and a control unit. The user input unit receives a user input. The storage unit stores software called by Application Programming Interfaces (APIs) corresponding to a plurality of functions, respectively. The communication unit sends a file comprising a list of the APIs to a client terminal, receives one of the APIs from the client terminal, and then sends an execution result to the client terminal. The control unit receives the API and performing a function corresponding to the API.
