Presence information is shared between a plurality of applications, to grasp a change of presence information of a different kind of application. An IM(X) server 3 receives a notification of a change of presence information from a client A1 (S902), and sends a change notification message for notifying the change of the presence information to a presence server 5 (S906). Then, the presence server 5 sends the change notification message received from the IM(X) server 3 to the IM(Y) server 4 (S908). The IM(Y) server 4 sends the change notification message received from the presence server 5 to a client B2 (S910).
摘要:
When starting subscribe for acquiring presence information, there is no need of acquiring an identifier of the presentity or an identifier of the group, which have been conventionally indispensable. There is provided a state information management system including a management server for managing state information on a plurality of terminals. Instead of specifying a presentity, a condition of the presentity, such as a value of presence, is specified for subscribing. For example, when subscribe is established by specifying the identical current position as a condition, subscribe for the user matched with the condition is automatically started and the presence can be acquired. When the presence of a partner or user himself/herself is changed to a different value, the presentity is automatically changed.

A data distribution system is provided which, in a network where data is exchanged between users, prevents the users from downloading malicious data without knowing whether the data he or she is going to download is the desired data. In a system configuration, a network administrator makes publicly known to the users, distributor identifiers uniquely assigned to data distributors in advance, and prohibits a data distribution by a user with a distributor identifier when the administration is notified that a malicious data has been distributed from the user, thereby securing reliability of the data distributors. A signature of the data is used to detect tampered data and prevent such data from being redistributed. Further, a user who tampered with the data is identified and then prevented from using the network.

Novel crystal modifications of (+)-catechin monohydrate and of (+)-catechin anhydrate more suitable for pharmaceutical preparations for reasons of higher stability against moisture and/or light and distinguished from hitherto known modifications by unique X-ray diffraction spectra are produced by specific recrystallization and/or crystal rearrangement processes and pharmaceutical preparations comprising the novel crystal forms.

Provided is a computer system, comprising a management server and a presence server. The user terminals include a first user terminal for originating a question and a second user terminal for responding to the question originated from the first user terminal. The management server comprising: an interface coupled to the network; a processor coupled to the interface; and a memory coupled to the processor. The management server calculates an unresponsive time taken until the second user terminal becomes ready to receive a notification of the question transmitted from the first user terminal by referring the presence information acquired from the presence server upon detection of an origination of the question from the first user terminal, estimates an expected response time of the second user terminal based on the calculated unresponsive time, and notifies the first user terminal of the estimated expected response time.
