Abstract: Disclosed is an image data generating method. Operations of emitting electromagnetic waves to an object and receiving scan signals scanning the object are performed by using a multi-static transceiver. First image data of a low resolution are generated based on the scan signals. when a first condition associated with the first image data is satisfied, second image data of a high resolution associated with a sub-region of the first image data are generated. When a second condition associated with the second image is satisfied, third image data based on the first image data and the second image data are generated.

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: Disclosed is a method for fabricating a terahertz device, the method including providing a substrate, doping a conductive impurity on an upper surface of the substrate to form an electrode layer, patterning the electrode layer to form antenna electrodes, and forming a photomixer between the antenna electrodes.

Abstract: Provided is a method and system for providing a QoS in a broadband convergence network deploying a mobile IP. In the method, a service and policy is defined at a first network design stage for guaranteeing the QoS of the broadband convergence network. QoS parameters corresponding to the defined service and policy are reflected in a DSCP field corresponding to the defined service. The DSCP field and the QoS parameters are applied to an access router in a management network. Accordingly, the QoS can be guaranteed to be suitable for the service and policy and a seamless handover guaranteeing the QoS can be provided.
