Abstract: In a diagnosis system using fluorescence information and acidity information and a diagnosis method using the same, the diagnosis system includes a fluorescence information obtainment part, an acidity information obtainment part, a derivation part, an acidity information calculation part and a diagnostic part. The fluorescence information obtainment part is configured to obtain fluorescence information from a sample and a specimen subject to diagnosis. The acidity information obtainment part is configured to obtain acidity information from the sample. The derivation part is configured to derive a correlation between the fluorescence information and the acidity information. The acidity information calculation part is configured to calculate acidity information of the specimen based on the fluorescence information obtained from the specimen, using the correlation.

Abstract: Disclosed are an apparatus and method for extracting synchronization by acquiring a boundary between uplink and downlink signals in 5G networks. In an embodiment, the synchronization extracting apparatus may include a reference detector and a synchronization extractor. The reference detector detects a start position of a radio frame from a signal broadcasted by a base station. The synchronization extractor collects resource allocation information and extracts synchronization by acquiring a boundary between an uplink (UL) signal and a downlink (DL) signal from the resource allocation information, based on the start position of the radio frame. The resource allocation information indicates information about arrangement of the UL signal and the DL signal in the radio frame. Other embodiments are possible.

Abstract: The present disclosure relates to an optical repeater system for 5th generation (5G) mobile communication. The optical repeater system does not require an additional optical wavelength for a plurality of remote units and can increase the transmission capacity by adding a remote unit without incurring an unnecessary cost, thereby facilitating high-speed and large-capacity data transmission. In addition, the optical repeater system can transmit/receive both a high-speed and large-capacity service signal, as an analog optical signal, and a management control signal, as a digital optical signal, between a master unit and a plurality of remote units. Also, the optical repeater system can selectively and differently compensate for propagation delay times of multiple paths between a terminal and a base station in a mobile communication system, especially, in the 5G mobile communication system.
