Abstract: A server including an image storage, an image processor, a progress managing unit, and a UI controller. The image storage stores medical images of different body regions of a subject. The image processor receives requests related to each medical image from one of multiple clients and executes processing of the medical images. The progress managing unit creates progress information on the processing of each medical image based on the stage of the processing performed by the image processor on each of the multiple medical images, and centrally manages progress information for multiple medical images. In accordance with the processing stage indicated by the progress information, the UI controller generates display screen data which presents the processing status of the medical images of the corresponding body regions on multiple screen regions corresponding to multiple body regions and transmits the display screen data to either one of the multiple clients.

Abstract: A communication support system is connected with a network enabling communication among user terminals and is capable of accessing a user information recording portion in which shared information concerning users and access information showing users who accessed the shared information are recorded. The communication support system includes: a user identification portion that acquires a communication start request from a user terminal and identifies an originator and a receiver; a retrieval portion that retrieves shared information concerning the receiver that the originator has not accessed from data recorded in the user information recording portion; and a control portion that, based on a result of the retrieval by the retrieval portion, controls the communication. Thereby, the communication support system can control whether or not to start the communication based on the presence or not of information about the receiver that the originator should confirm.

Abstract: In a presence system in which one user users a plurality of terminals, dynamically changing buddy lists are synchronized between the terminals. A presence notification message is sent to all the terminals of the user. The timing of sending includes, for example, when the presence information of a buddy is updated, when a new buddy is set, when display attribute information is updated, when a buddy is cancelled, and when a presence notification of unknown presentity is made. Thus, when one user uses a plurality of terminals in the presence system, dynamically changing buddy lists can be synchronized between the terminals. In addition, the display formats of the buddy lists do not differ from one terminal to another, and the same display format is attained.

Abstract: A ubiquitous communication system that can be used without changing a user ID etc. of a terminal of others or causing problems such as information leakage is provided.

Abstract: An object of the present invention is to manage presence update by publishers that a presentity does not recognize. When the presence server 100 receives status information that indicates a status of presentity A from publisher B (#1), the presence server 100 stores it in the history table 9 and transmits a change notification to a watcher C (#3). Subsequently, the presence server 100 makes an inquiry to presentity A as to whether or not to allow an update by publisher B (#4). When it is allowed (#5, #6), publisher B is added in the allow list 8a of the allow list DB 8 (#7). Also, presence information is generated based on status information retrieved from the history table 9 (#8), is notified to the watcher C and is stored in the presence management DB 2b (#9, #10). When it is denied (#11), publisher B is added in the deny list 8b of the allow list DB 8 (#12). Also, status information received from publisher B is deleted from the history table 9.

Abstract: The input unit stores data input by the user in the data storage. The status determiner determines reception status of the screen data to be one of three statuses of “abnormal”, “normal”, and “recovery” from “abnormal” to “normal” on the basis of frame losses. In a case of the “abnormal” status, a transmission controller does not read the input data stored in the data storage. In a case of the “normal” status, the transmission controller reads the input data stored in the data storage, transmits the input data via the transmitter, and deletes the input data stored in the data storage. In a case of the “recovery” status, the transmission confirmer instructs the output unit to output the input data stored in the data storage to ask the user whether to transmit the input data to the server.
