Abstract: The present invention relates to a proton-transport vesicle and a method for preparing the same, the proton-transfer vesicle comprising: (a) a single phospholipid bilayer liposome; (b) a rhodopsin protein; and (c) a photosystem II protein, wherein the rhodopsin protein and the photosystem II protein are inserted and located in a bilayer of the liposome. Since the heterologous photosensitive proteins are inserted and located in the bilayer of the liposome, the vesicle has an absorption wavelength band of the whole region of visible light by utilizing absorption bands of different lights of the respective photosensitive proteins. Thus, the restricted efficiency caused by utilizing only a specific wavelength in existing organisms or artificial vesicles was improved, and the wavelength region can be enlarged to the all wavelength ranges of visible light.

Abstract: An electrical dust-collecting filter is provided. The electrical dust-collecting filter includes a dust-collecting unit having a dust-collecting body and dust-collecting electrodes configured to generate an electrical field in the dust-collecting body. The dust-collecting body has a plurality of air channels laterally formed therethrough and discharge apertures formed in upper and lower surfaces thereof at inlets of the plurality of air channels. A discharge unit is integrally formed with the dust-collecting unit at the inlets of the plurality of air channels to facilitate corona discharge in air introduced into the inlets of the plurality of air channels.

Abstract: Disclosed are user equipment and a base station in a carrier aggregation system, and a call admission method thereof. The user equipment includes a plurality of physical layers, and the base station provides multiple component carriers. When messages for connection setup are transmitted and received between the user equipment and base station, the messages include information about what component carriers are selected by the physical layers, information about what component carriers are selectable by the physical layers, and information about calculations for uplink timing alignment, and call admission control and load balancing is performed based on the information included in the messages. Accordingly, in the carrier aggregation system, quicker call admission and load balancing are achieved.

Abstract: The present invention relates to a method and a process of preparing precipitated calcium carbonate of high purity by extracting calcium ion contained in an alkali ion-containing inorganic material such as mineral, steelmaking slag and waste concrete with the use of an acidic aqueous solution, separating other metal ions from the extracted solution, preparing an alkaline earth metal hydroxide using an alkaline aqueous solution and then contacting the same with carbon dioxide.

Abstract: Disclosed is a cooling system for a vehicle, in which coolant coolant, a blend of an antifreezing solution and water flowed into a radiator generates turbulent flow when a vehicle is in a state of a critical driving mode of a vehicle for example, a hill-climbing mode, thereby enhancing heat radiating performance and reducing pressure drop amount at the same time.
