A learning-support device offers a sufficient learning effect even in a field of learning that sets its goal on mastering a motion itself. A question-screen display part displays a question-screen composed of a question and moving images as choices for an answer. A selection reception part receives a user-selection indicating which of the moving images on the question-screen is selected by a user. A correct/incorrect determination part determines whether the user-selection is correct or incorrect. When the user-selection is determined as correct, a correct-answer-explanation-screen display part displays a correct-answer-explanation-screen including an explanation for the correct answer and the correct moving image. When the user-selection is determined as incorrect, an incorrect-answer-explanation-screen display part displays an incorrect-answer-explanation-screen including an explanation for the incorrect answer and the correct moving image.

A justification/authentication personal certificate system stores in a remote database a counterpart of an identifier and a digital watermark contained in the personal certificate. The personal certificate includes the digital watermark embedded in an authentic image such as a facial photograph, a retinal scan, or a fingerprint. When the personal certificate is used, the authentic image is read from the personal certificate, and the digital watermark information is extracted. The digital watermark information and the identifier are compared with the counterparts stored in the database. If the extracted digital watermark information is identical to the information in the database, then the personal certificate is judged to be unjustifiable. In one embodiment, at least one of the identifier and digital watermark are changed each time the system justifies the personal certificate.

The optical recording medium comprises a light-transmitting substrate 11 having a spiral groove 11a formed thereon and a recording layer 21 containing an organic dye wherein the average inclination angle θa of the wall of the groove 11a on the inward side thereof is greater than the average inclination angle θb of the wall of the groove on the outward side thereof. In this arrangement, when the recording layer 21 is formed by a spin coating method, the dispersion of the thickness of the recording layer 21 inside the groove 11a can be prevented, making it assured that the recording layer 21 can be provided with a desired thickness over an area inside the groove 11a ranging from the inward side thereof to the outward side thereof. As a result, heat of laser beam emitted during recording can be almost uniformly dissipated over the area inside the groove ranging from the inward side to the outward side thereof to eliminate the effect of thermal interference between marks, making it possible to secure a wide power margin during a high speed recording.

Access from a terminal of an outside network to a server of an inside network is put under control. A repeater and the server permit a packet transmission from the terminal to the server under limited conditions. When the server acknowledges connection for the permitted packet, the transmission conditions for packets to be sent to the server are loosened. After then, packet transmission between the terminal and the server is controlled under the loosened transmission conditions. As for encrypted packets, the server decodes the encrypted packets and notifies the relevant information to the repeater.

An object of the present invention is to reduce information volume going through a network when a multi-media E-mail is transmitted/received therethrough, which includes various types of media information being temporally and/or spatially related to one another. To attain the object, a return mail is composed by utilizing any object (received object) included in an incoming mail. Thereafter, the return mail is structured in a format for a multi-media E-mail including every object included in the return mail exclusive of the already-utilized object(s) and control information indicating how the objects in the return mail are temporally and/or spatially positioned, and then is transmitted to a computer system from which the incoming mail was transmitted.

The communication system supports reservation of network resources. The base stations relay packets among the terminals, and perform priority control based on the priority set to the packets. In the terminal, the communication-managing table stores communication information of own terminal and a partner thereof. The packet-transmitting unit, setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.
摘要:
A resource request is continuously accepted within predetermined time by a resource management device that comprises a resource request accepting unit, a measuring unit, and an allocating unit. The resource request accepting unit accepts a resource request that is necessary for communication. The resource request includes priority of communication. The measuring unit measures the accepting time when the resource request accepting unit accepts the resource request. The allocating unit allocates resource to the resource request accepted in accepting time based on priority. As a result, suitable resource allocation according to the priority instead of the order of arrival is realized.

The present invention provides an aqueous curable resin composition which comprises: [A] a resin component containing, as functional groups, a specific aprotic onium salt-containing group, a hydroxyl group, an epoxy group, and a hydrolyzable group directly bound to a silicon atom or a hydroxysilyl group, and [B] a metal chelate compound selected from aluminum chelate compound, zirconium chelate compound and titanium chelate compound. The composition of the present invention is an aqueous composition which has an excellent storage stability and good curability and is capable of giving a cured product having a high water resistance.
摘要:
A resource management server that manages information concerning the resource reservation status and the information of groups of all electronic equipments connected to hubs. When an electronic equipment is newly connected to a port of one of the hubs, the electronic equipment issues a resource request and the group information to the resource management server. The resource management server sets up a network path between the newly connected electronic equipment and the other electronic equipments belonging to the same group as the newly connected electronic equipment, and judges if the resource request can be accepted on the setup network path.
摘要:
A terminal comprises a packet receiving unit, a packet sending unit, a link-state detecting unit that detects a link-up to a switching device, a configuration-change notifying unit, and a resource reservation table. When the link-state detecting unit detects a link-up, the terminal notifies network configuration information and network resource reservation information to a management device. When a link state is changed, the management device can immediately manage the network based on the latest network configuration information and the latest network resource information.
