Abstract: The method for constructing precast coping for bridge enables for a segment to be match-cast manufactured at the top of a pier body. The method may be applied to small and medium size bridges by introducing transverse tendon force to each segment through tendons after manufacturing a subsegment which is match cast manufactured using sides of a pre-made segment as molding. Further, the method for constructing precast coping for bridge enables to construct precast coping for bridge by easily lifting the coping, which is assembled on the ground, using lifting lugs that are formed on the top of manufacturing segments.

Abstract: Provided are a method, client and system for reservation access to a management server using a one-time password. A generated personal identification number (PIN) is transmitted to the management server when a reservation time comes. The management server generates a random number encrypted using the PIN and transmits the random number to the client. The random number encrypted using the PIN is received, the received random number is encrypted by a symmetric-key algorithm using a client secret key and is transmitted to the management server. The management server receives the random number encrypted using the client secret key, and decrypts the received random number using a server secret key and the PIN. A random number before the encryption using the PIN is compared with a decrypted random number, and access of the client is accepted if the two numbers are identical.
