    Abstract: PURPOSE: An acrylic derivative of cardanol is provided to ensure excellent stability compared with conventional cardanol or derivatives thereof, and excellent polymer reactivity and polymerization. CONSTITUTION: A cardanol derivative is represented by chemical formula 2. In chemical formula 2, A is hydrogen or methyl, and R is represented by chemical formula 2-a. The cardanol is obtained from cashew nut shell liquid. A method for preparing the cardanol derivative comprises a step for reacting cardanol with glycidyl (meth)acrylate in the presence of a base catalyst and then purifying the resultant.

    Abstract: The present invention relates to a technology for preventing the decline of signal delivery efficiency through a probe by controlling the impedance matching between a power amplifier and the probe by using the variability of an impedance variable circuit in an apparatus for thermotherapy when a thermotherapy is conducted. The apparatus for thermotherapy of probe type includes a power detector outputting DC voltages corresponding to electric energies of incident waves and reflected waves, which are separated from each other and output from a directional coupler; an arithmetic unit for calculating a reflection coefficient based on the DC voltages; and a control unit for controlling the impedance variable state of the impedance variable circuit to form impedance matching between the power amplifier and the probe.
