Abstract: It is intended to provide a method of three-dimensionally culturing normal joint chondrocytes; the production and supply of chondrocytes; and a transplantation material to be used in an injured site in a joint tissue.

Abstract: It is an object of the present invention to provide a QoS controllable communication device and communication system. A device 114 such as a first IP telephone comprising a QoS control unit 121 of the present invention transmits first transmission control data to a device 111 such as a PC performing lower priority communication. The first transmission control data includes data for changing the communication path of the lower priority communication, and the PC 111, having received the first transmission control data, performs subsequent lower priority communication through the first IP telephone or other device 114, enabling the first QoS control unit 121 to perform priority control. Because the present invention employs widely used protocols such as ARP and ICMP, the device 111 receiving the control data does not need protocols specific to the present invention.

Abstract: An encryption information determination section in a communication device negotiates an encryption algorithm to be used for encrypted communications with an encryption information determination section in a network camera, which is a communication counterpart. At this time, the encryption algorithm to be selected is varied depending on the CPU load of the communication device. That is, if the CPU utilization rate is high, a low-load encryption algorithm is selected, and if the CPU utilization rate is low, a high-load encryption algorithm is selected. A encryption/decryption processing section performs code processing using the encryption algorithm selected by the encryption information determination section.

Abstract: A transmitting side communications device transmits a Delete Payload of an IPsec SA using an ISAKMP SA that satisfies a transmission condition, and more preferably using all ISAKMP SAs that exist between communications devices. The receiving side communications device accepts a Delete Payload by an ISAKMP SA that satisfies a reception condition, and preferably any ISAKMP SA that exists between the communications devices. As long as there exists an IPsec SA that was established using the ISAKMP SA, it remains possible to maintain an ISAKMP SA, without completely deleting it, and to transmit and receive a Delete Payload by that ISAKMP SA.

Abstract: The present invention relates to a new method for extraction and purification of cartilage type proteoglycan, and is to provide a method for extraction of crude proteoglycan characterizing to use acid as eluting solvent of cartilage.

Abstract: Upon receipt of a public value X from a device A, a device B estimates a time to be taken for calculation of a public value Y and a time to be taken for calculation of a common key K, and then calculates a required operation time Tb required at the device B for a key exchanging process for transmission to the device A to report a response delay time S306 and S307. Then, the device B actually calculates the public value Y and the common key K S309 and S310. Upon receipt of the required operation time Tb, the device A extends a waiting limit (timeout time) for a response from the device B to a time when the required operation time Tb elapses from the reception S311.

Abstract: An encryption information determination section 32 in a communication device 24 negotiates an encryption algorithm to be used for encrypted communications with an encryption information determination section 18 in a network camera 12, which is a communication counterpart. At this time, the encryption algorithm to be selected is varied depending on the CPU load of the communication device 24. That is, if the CPU utilization rate is high, a low-load encryption algorithm is selected, and if the CPU utilization rate is low, a high-load encryption algorithm is selected. A encryption/decyption processing section 38 performs code processing using the encryption algorithm selected by the encryption information determination section 32.
