Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

Abstract: The present invention relates to an implantable nerve stimulation device, which includes: a body part which is formed of a metal that ultrasonic waves can be transmitted, and includes a stimulation surface and a charging surface facing each other; a header part which is made of a non-metal and is located at one end of the body part; a cover which includes a stimulation electrode, a hinge part rotatably coupled to one side of the stimulation surface, and a coupling part detachably coupled to the other side of the stimulation surface, is positioned above the stimulation surface to interpose a nerve between the electrode and the stimulation surface; and power generation elements which are located inside the body part and are electrically connected to the electrode.

Abstract: A method includes obtaining a color transformation matrix that removes color distortion of an original color histogram of a target color space for an input image of an original color space; obtaining a color transformation image of the original color space from which color distortion of the input image is removed using the color transformation matrix; and obtaining a space transformation image with a minimum target loss value between an output vector of a neural network for one of candidate images and each of a plurality of candidate class vectors of the input image, the candidate images being spaced apart from the color transformation image of the original color space by a distance less than a threshold.

Abstract: A floor selection operation panel for elevating equipment may include a panel including an opening, an electric compartment room disposed at a rear side of the panel, and a floor selection button disposed inside the electric compartment. The floor selection button may include a button body including a first body and a second body selectively exposed to the outside through the opening, a rotation shaft for rotating the button body, a printed circuit board disposed at a rear side of the button body, the printed circuit board including a switch and a germicidal lamp irradiating light toward the button body, and an elastic member disposed between the rotation shaft and the first body and between the rotation shaft and the second body.

Abstract: A system and method for selecting a path for a voice call over an access network from a plurality of access networks. The system includes a call negotiation agent configured to store price information associated with the voice call in which the price information is provided through at least one of the plurality of access networks. According to the present invention, a call negotiation server is configured to store the price information associated with a voice call and store the estimation information indicative of the quality of the access networks after the voice call through the plurality of access networks is completed.

Abstract: A nonstop service system using voting and a method for updating and providing information in the nonstop service system. The nonstop service system includes a plurality of groups of nodes for storing and managing information on the basis of identifiers for distinguishing clients, each group including a plurality of nodes each of which is capable of storing and managing information independently. The nonstop service system further includes a control dispatcher server, which is located between the group of nodes and the clients and manages state information and connection information of the nodes belonging to the plurality of groups of nodes.

Abstract: Disclosed are a presence based telephony system and a call routing method thereof. The telephony system includes a presence server for managing presence of telephone service subscribers, and it routes the call dialed to the subscriber to one of the subscriber's wired/wireless telephone terminal or a VoIP terminal accessed through a VoIP gateway according to the subscriber's presence information established in the presence server. According to the present invention, the user uses a VoIP terminal connected to the Internet to receive calls generated to the previously subscribed wired/wireless telephone number without spatial restrictions. Also, the user can use the wired/wireless telephone service without an additional communication device if he has a VoIP terminal connected to the Internet when he buys no expensive telephone at the time of subscribing to a wired telephone service or a mobile telephone service.

Abstract: The present invention relates to a novel and improved process for preparing 4-acyloxy-2-azetidinone derivatives having the following formula (I) which are useful as an intermediate for synthesis of penem or carbapenem compounds: ##STR1## in which R.sub.1 represents a hydroxy-protecting group; and R.sub.3 represents an acyl group, which comprises reacting an azetidinone derivative having the following formula (II): ##STR2## wherein R.sub.1 is defined as above and R.sub.2 represents an alkyl group or an aryl group, with a N-haloacylimide in the presence of an organic carboxylic acid or a salt of an organic carboxylic acid.The present invention uses the organic compound, N-haloacylimide, as the reactant rather than the heavy metal reactant used in the prior art, and thus provides an economical advantage and does not cause any problem related to safety and waste disposal after the reaction.
