Abstract: Disclosed herein are a method for analyzing heavy metal removal efficiency using phase difference analysis and an apparatus using the method. The method for analyzing heavy metal removal efficiency using phase difference analysis includes applying a magnetic field to a magnetite onto which a heavy metal is adsorbed, based on a first solenoid coil and a second solenoid coil that have an identical winding direction, applying a high-frequency signal to the magnetite, based on a third solenoid coil having a winding direction that differs from that of the first solenoid coil and the second solenoid coil, detecting a high-frequency signal transformed by the magnetite, and calculating a phase difference between a previously detected default high-frequency signal and the transformed high-frequency signal, and analyzing an efficiency of heavy metal removal by the magnetite by measuring a concentration of the heavy metal based on the phase difference.

Abstract: Disclosed herein are a signal transmission/reception method for signal analysis in FMMD technology and an apparatus using the method. A signal transmission apparatus includes a signal generation unit for generating two sine wave signals having different frequencies in consideration of a voltage of an excitation coil included in a magnetic particle measurement sensor, a signal addition unit for generating an input signal for producing a magnetic field by electronically adding the two sine wave signals, a differential signal generation unit for generating a differential signal for the input signal to minimize transmission noise, and a signal transmission unit for amplifying voltages of the input signal and the differential signal and transmitting the amplified input signal and differential signal to the excitation coil so as to produce a magnetic field in the excitation coil and apply the magnetic field to a measurement target sample.

Abstract: Disclosed herein are an apparatus for writing a motion script and an apparatus and method for self-teaching of a motion. The method for self-teaching of a motion, in which the apparatus for writing a motion script and the apparatus for self-teaching of a motion are used, includes creating, by the apparatus for writing a motion script, a motion script based on expert motion of a first user; analyzing, by the apparatus for self-teaching of a motion, a motion of a second user, who learns the expert motion, based on the motion script; and outputting, by the apparatus for self-teaching of a motion, a result of analysis of the motion of the second user.
