摘要:
The present invention provides a novel biphenyl compound or pharmaceutically acceptable salts thereof, methods for preparing the same, and pharmaceutical compositions for preventing or treating diabetic complications containing the same as an active ingredient. Novel biphenyl compounds, according to the present invention, effectively suppress generation activity of advanced glycation end products, which cause diabetic complications and are a criterion for evaluating the effectiveness of a treating agent for diabetic complications, and show an excellent therapeutic effect on retina blood vessels, increased occludin, and decreased angiogenic growth factor in actual diabetic retinopathy induced retina. Thus, novel biphenyl compounds according to the present invention can be used effectively as an active ingredient in compositions for preventing or treating diabetic complications such as diabetic retinopathy.

In accordance with another representative embodiment, a high-frequency signal transmitter a power amplifier configured to supply a high-frequency signal; an antenna configured to transmit the high-frequency signal; a transmission line configured to transfer the high-frequency signal from the power amplifier to the antenna; and an impedance matching circuit connected to the transmission line. The high-frequency signal transmitter also comprises a mismatch detector. The mismatch detector is configured to designate a comparatively poor linearity region and a comparatively good linearity region by dividing a Smith chart into the two regions based on Adjacent Channel Power Ratio (ACPR) contours drawn on the Smith chart at a point on the transmission line where the impedance matching circuit is connected, to measure a time-dependent reflection coefficient of the high-frequency signal transmitter in terms of a phase and a magnitude, to determine whether the reflection coefficient is located in the comparatively poor linearity region or the comparatively good linearity region, and based on a result of the determination, to improve the linearity of the high-frequency signal transmitter.

Provided are an apparatus and method for processing motion picture and a record medium, which decompose a motion picture into unit frames and insert copyright information into the unit frames, enabling to determine the infringement of copyright when the motion picture is illegally circulated. The apparatus includes a processing unit, a merging unit and an output unit. The processing unit decomposes a motion picture into a plurality of unit frames, and generates a main frame, a sub-frame including copyright information for the motion picture and a degree frame which is paired with the sub-frame, based on the unit frames. The merging unit merges the sub-frame into the main frame according to a degree of mergence of the degree frame. The output unit continuously outputs the merged frames in time order.
