Abstract: When the status of a client X is changed to a status i, a group management unit generates a group agent Xi, corresponding to the status i and registers the generated group agent in the server S, and the presence issuing unit issues the status i and the identifier of the group agent Xi. Initially, a member management unit of the group agent xi manages the client X only. When other clients, such as clients B and C, that are observing the status of the client X send an instant message (IM) to the group agent Xi identified by the issued identifier, an IM delivery unit of the group agent Xi adds the clients B and C, which are IM senders, to the members managed by the member management unit and sends the IM to all members.

Abstract: The present invention provides a PoC system which has the following capabilities: 1) it enables communication content to be confirmed afterwards; 2) by recording communication content in conjunction with information such as a caller identifier, it makes it easy to retrieve communication content afterwards; 3) it can record communication content only when this is necessary; 4) it can change as desired the criterion for deciding whether or not to record communication content; 5) it can record even during communications that include off-record content. Accordingly, when PoC group communication is taking place, the exchanged communication content is recorded during each session. Recording is only carried out when it is decided that recording is necessary. It is also possible to change whether communication content is recorded or not on a per-utterance basis.

Abstract: A communication agent apparatus includes at least one mobile unit, a presence information inquiring unit, a handling method determination unit, and a handling method execution unit. The mobile unit transports a communication device. The presence information inquiring unit acquires presence information indicating the current situation of a called user. The handling method determination unit determines a handling method for communication made from a calling user to the called user on the basis of the acquired presence information. The handling method execution unit executes the determined handling method. When the handling method determination unit determines a handling method of delivering a communication device used for communication to the called user, the mobile unit delivers the communication device to the called user in accordance with a move command from the handling method execution unit.

Abstract: A document processing apparatus implemented in a client/server system to add and modify a document conversion function without modification for either client or server. The apparatus comprises a client requesting acquisition or storage of a document, a server performing management such as transfer and storage of the document, a network connecting the client and the server, and a proxy server existing on the network and relaying interaction between the client and the server. The proxy server has a document data conversion section for performing conversion of the document based on the structure of document.

Abstract: A polymer light emitting material, wherein the material has a light emitting mechanism based on transition from an excited triplet state to a ground state or transition through an excited triplet state to a ground state of an electron energy level, and the material comprises a nonionic light emitting part which constitutes a part of the polymer or is bound to the polymer. The polymer light emitting material exhibits high light emission efficiency above 5%, which is the limit of external quantum efficiency of fluorescence and can be designed so as to have a large area and hence are suitable for mass production of organic light emitting devices.

Abstract: An information management system allowing the improved efficiency of data transfer in a network composed of a server and a plurality of clients is disclosed. The server stores a structured document to be shared among the clients and each of the clients stores a duplication of the structured document. When a part of the structured document is updated, the server notifies the clients of an update of the structured document using an updated minimum unit of the structured document including the updated portion of the structured document.

Abstract: A presentity service client has a presentity that issues presence information to a presence service and a watcher which observes presence information for other presentities; a presence change rule holding part holds a presence change rule; and a presence calculating part changes the presence information for the presentity, using as a trigger a change in presence information of other presentities, based on the presence information of other presentity acquired by the watcher and in accordance with the presence change rule held by a presence change rules holding part.

Abstract: The invention relates to a light-emitting material having high emitting efficiency, high luminance and durability for use in an organic light-emitting device and to an organic electroluminescent (EL) device, in which the light-emitting material is used. The light-emitting material contains a light-emitting substance which is spatially constricted and confined in an order of two dimensions or more, thus providing a high efficient organic light-emitting device based on emission of phosphorescence from an excited triplet state.

Abstract: The object of the present invention is to provide a hair treatment having high dechlorinating and hydroxy radical-scavenging abilities, excellent safety to skin, low irritation and sufficiently high storage stability required in view of the production of preparations, and provide a hair care composition using the hair treatment agent.

Abstract: An organic polymeric phosphorescent compound that is stable and emits very highly efficient phosphorescence, used as a material of an organic light-emitting device is provided. Also, an organic light-emitting device employing the organic polymeric phosphorescent compound's provided. The phosphorescent compound according to the present invention is a neutral organic polymeric phosphorescent compound emitting phosphorescence and used in an organic light-emitting device, characterized in that a phosphorescent unit being a repeat unit for emitting phosphorescence and a carrier transporting unit being a repeat unit for transporting a carrier are included.

Abstract: The contents conversion system of this invention comprises a style sheet storage means for storing a plurality of style sheets and an XML document storage means for storing XML documents for which the style sheet specifications are undefined, that selects a style sheet from the style sheet storage means, based on an XML document identified from the XML document storage means as the XML document required in relation to a contents request from client system and based on circumstance information of the client system from which the contents request is received and on the identified XML document.
