Abstract: The awareness of users regarding uses of reused products are raised, and their awareness regarding the environment is thereby increased. An information processing system includes information acquisition means for acquiring reuse information, the reuse information being information about an operating status of a reused product; storage means for storing association information associating the reused product with information about a terminal of a previous owner of the product before the product is reused as the reused product; and transmission processing means for transmitting, based on the association information stored in the storage means, the reuse information of the reused product acquired by the information acquisition means to a terminal associated with the reused product.

Abstract: The information processing system includes: a data acquisition unit that acquires component data of a reusable product related to environmental contribution of the reusable product including at least the number of times of reuse of the reusable product; a selection unit that selects a candidate of the reusable product that is a replacement component candidate when the user replaces the component; a calculation unit that calculates an environmental contribution degree of the candidate of the reusable product selected by the selection unit based on the component data of the reusable product acquired by the data acquisition unit; and a presentation unit that presents, to the user, the environmental contribution degree of the candidate of the reusable product calculated by the calculation unit together with the candidate of the reusable product selected by the selection unit.

Abstract: A distributed processing system wherein client-side process is simplified and system reliability is improved. An information transmission requesting section makes a request for transmission of information, and an information providing section provides received information to a user. An information management section manages the information, and an information relaying/transmitting section relays the information to be transmitted to a client application. An account authentication section verifies authenticity of account of the client application, and an information storage section stores the information. After the authenticity is verified, a service application control section controls the start and termination at logon and logoff, respectively, of a service application corresponding to the client application.

Abstract: An object management system and data processing system which enable the containment relationships among a plurality of resource managers to be changed without affecting client applications which use services of those resource managers. A tree manager maintains tree structure data that defines the containment relationships among resource managers, together with identification data that is used to distinguish between them. From this tree structure data, an object manager builds a containment tree to grasp the containment relationships among the resource managers. When a client application issues an operation request to one of the resource managers, a message processor receives and forwards it to the object manager. The object manager then searches the containment tree to find identification data of a relevant resource manager for which the received operation request should be destined, thus sending the request to the found destination resource manager.

Abstract: An object-oriented type information managing system includes a network control system and a network managing system, the network control system includes an upper control object, and the network managing system includes a plurality of processes each having one or more objects. One object is used as a relay object for receiving a request message from the upper control object, and other objects are used as request message destination objects (or, control target objects) managed by the relay object. Each destination object returns a response message. Further, at least one process in the plurality of processes comprises a reply object for receiving the response messages sent from the destination objects and directly sending them to the upper control object.

Abstract: A method of controlling objects in an information processing system includes the steps of representing objects by a tree having a hierarchical structure, providing each of the objects with a first operation-target flag which indicates whether a corresponding object is a target of a given operation, and performing the given operation on an object upon receiving of an object handling request for the given operation only if the first operation-target flag of the object indicates that the object is a target of the given operation.
