Abstract: The present invention relates to a method for detecting a void in a concrete composite member covered with a steel plate using a thermal image, and a method for managing the construction of a concrete composite member covered with a steel plate by applying same. According to the present invention, since the presence of the void is determined based on the steel plate surface temperature measured using the thermal image during the construction of the concrete composite member covered with the steel plate, the void generation may be precisely expected.

Abstract: A contents receiving device may automatically receive contents, and a recording medium may store a contents receiving program. The contents receiving device may refer to an agent table, receive contents having the greatest weight of the agent having the least preference deviation as a top priority from a contents providing server or a P2P network, and store the contents in a contents storage unit. Therefore, the contents receiving device and a device for operating the contents receiving program may automatically download contents satisfying the user's preference. Further, the devices may allow easy finding of user preferences on the contents and similarities on contents preference with respective agents.
