PURPOSE: Fall protection shoes, a fall protection method using the same, and a record medium of the method are provided to prevent fall accident by using an electromagnet, and to able to immediately signal through a transfer module in case of fall accident. CONSTITUTION: Fall protection shoes comprise an electromagnet(10), a pressure sensor(20), a state information output unit(30), a power control unit(40), a power supply unit(50) and a piezoelectric element(60), a transfer module(70), and a GPS receiving unit(80). The electromagnet on the bottom of the fall protection shoes exhibits attractive forces to metal surfaces. The pressure sensor measures pressure based on the weight of a wearer. The state information output unit outputs information about a state of a wearer. The power control unit outputs operation signals for operating the electromagnet. The power supply unit supplies current signals to the electromagnet. The piezoelectric element supplies power to the power supply unit based on the pressure. The GPS receiving unit recognizes an abnormal location change of a wearer as a fallen state, and allows detection of the location of the wearer after accident.

PURPOSE: A device and a method for estimating the improvement in concrete curing strength using guided ultrasonic wave are provided to reduce construction time by optimizing curing time of concrete. CONSTITUTION: A device for estimating the improvement in concrete curing strength using guided ultrasonic wave comprises a piezoelectric sensor(10), an arbitrary waveform generator(20), a self sensing circuit(30), a digitizer(40), and a controller(50). The piezoelectric sensor is installed in the inner side or the outer side of a concrete structure and generates guided ultrasonic wave by receiving a frequency signal from outside. And the piezoelectric sensor receives reflected wave from the concrete structure. The arbitrary waveform generator is connected to the piezoelectric sensor. The self sensing circuit converts the reflected wave into a voltage signal. The digitizer eliminates noise from the voltage signal and extracts the frequency in a specified area. The controller measures a strength change of the concrete structure.
