Abstract: A call control device including: a memory, and a processor coupled to the memory and configured to: receive a call request from a communication device, a source of the call request being a terminal, the call request being transferred by the communication device when the terminal is registered in a management device, and request the management device to deregister the terminal when the call control device is determined that the call control device is attacked from the terminal based on the call request.

Abstract: When a connection control device determines that the connection control device is in a congested state, based on whether a usage of at least one of hardware resources necessary for call processing to establish a call connection is equal to or more than a predetermined threshold value, the CPU of the connection control device forcefully disconnects an established call connection after a connection available time elapses, and, when an INVITE message is transmitted from a terminal device, the CPU of the connection control device receives the INVITE message, calculates the wait time, creates and transmits a response message stating the wait time, and stores the message as a reserved call on a reservation list.

Abstract: A water vapor plasma generating apparatus which is able to generate water vapor plasma stably is provided. By applying the water vapor plasma generated by the apparatus to an object to be treated, a sterilization and disinfection treatment can be performed. In addition, by applying the water vapor plasma generated by the apparatus to a substance containing an oily ingredient, an antioxidative treatment can be performed.

Abstract: A communication system capable of securely preventing illegal use of addresses and enhancing confidentiality of communication. Based on an originating-side real address which is the real address of an originating-side client terminal and specific information included in a registration message, a conversion data generator generates conversion data which the local server alone can convert to a receiving-side real address which is the real address of a receiving-side client terminal, and transmits the conversion data to the originating-side client terminal.

Abstract: A tampering monitoring apparatus (10) for monitoring whether or not application information in an information processing device (100) is tampered includes: a tampering verification program storage section (117) for storing a tampering verification program for verifying whether or not the application information is tampered: a first processing section (110) capable of verifying whether or not the application information is tampered, by using the tampering verification program: and a second processing section (200), communicably connected to the first processing section (110), capable of receiving the tampering verification program from the first processing section (110) and verifying whether or not the received tampering verification program is tampered. When the second processing section (200) verifies that the tampering verification program is not tampered, the first processing section (110) verifies whether or not the application information is tampered, by using the tampering verification program.

Abstract: A broadcast information receiving terminal which notifies a user, when a broadcast program is unreceivable, of such unreceivability, and also notifies the user, when a reception of the broadcast program has been recovered, of such recovery of the reception is provided. In the broadcast information receiving terminal which reproduces a TV number or the like, an at-reception-recovery-time processing preprogramming control section (3) determines, when a reception of a desired broadcast program which was determined as unreceivable has been recovered, whether or not to notify the user that the reception of the broadcast program has been recovered. An at-reception-recovery-time processing section (7) notifies the user that the reception of the desired broadcast information has been recovered.
