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 an apparatus and method for controlling the capture of an image of a cut surface. The apparatus for controlling the capture of an image of the cut surface of material that is cut using a cutting device includes a signal generation unit for outputting a signal, a sensor unit for sensing the output signal using multiple sensors and generating a sensing signal, and an image capture control unit for controlling an image-capturing operation of an imaging device, which captures the image of the cut surface, using the sensing signal.

Abstract: The present invention relates to a motion based interactive service method and system which provide various motion based interactive services such as repeated training of a motion, progressive difficulty adjustment, evaluation for every body part, and feedback based on the analysis result of the user's motion so that a user of a dance game or a dance lesson can efficiently perform a motion based performance or take a lesson by easy and various methods.

Abstract: The present invention provides a choreography searching system and method based on a motion inquiry which inputs a choreography video which is captured by a user at real time when the user dances in front of a camera and inputs the choreography video as an inquiry to compare the choreography with choreographic works such as K-POP stored in a choreography database to provide a list of choreographic works which are arranged in the order of similarity in order to provide intuitive choreography input based search rather than text based search such as a music title, a choreographer, or a name of a unit motion.

Abstract: A communication method in a network robot system having a middleware processing communication between a plurality of sensors, a server, and a robot, the method including: setting previously a communication framework of the middleware for distributed processing of function of the robot by using the plurality of sensors and the server; and performing a communication between the plurality of sensors, the server and the robot by using the communication framework set previously, wherein one of synchronous and asynchronous operations is performed according to a size of data for a remote object called from the robot.

Abstract: A method for eliminating state objects by using an object transaction service coordinator is disclosed. The method provides the state object delete unit and the state object delete adapter in the java transaction service. At the completion step of an object transaction, the state object delete unit in the state object delete adapter deletes a transaction state manager and objects, which are excessively occupied a memory for improving the repeatedly performed object transactions.

Abstract: A parallel logging method for a transaction processing system for simultaneously executing transactions of a plurality of application programs is disclosed. According to the method, a transaction control section instructs transaction participants to execute a transaction preparing step and a transaction commit step in accordance with transaction end requests of the application programs that have executed transaction operations. A log queue manager receives a log write request for status information of the transactions requested from the transaction control sections. Then, a plurality of log managers simultaneously execute the log write of the corresponding transactions in parallel in accordance with a request of the log queue manager that has received the log write request.
