Abstract: An apparatus for punching an anchor bolt insertion hole is disclosed. The apparatus enables punching work for forming the anchor bolt insertion hole, of which the bottom side is wider than an inlet, on a panel surface for constructing a concrete structure to be performed regardless of the skill of a worker. During operation, the apparatus provides the movement direction of a hammer drill into the vertical direction and the inclination direction so as to enable precise punching work, and doubly arranges springs, which are elastic devices for adjusting the movement range of the hammer drill, so as to uniformly maintain the angle and size for cutting a wall such that a cross-sectional diameter is large at a portion adjacent to the bottom of the anchor bolt insertion hole.

Abstract: Provided are a system and method for protecting private information of UICC. The system includes an initialization management server and a short message service center. The initialization management server generates an initialization station incoming message which includes an initialization command for initializing private information stored in a UICC according to an initialization request to the private information of the UICC, and uses a phone number assigned to the UICC as a reception number. The short message service center transmits the initialization station incoming message transmitted from the initialization management server to the phone number assigned to the UICC.
