Abstract: The inventive concept provides a teaching method for teaching a transfer position of a transfer robot. The teaching method includes: searching for an object on which a target object to be transferred by the transfer robot is placed, based on a 3D position information acquired by a first sensor; and acquiring coordinates of a second direction and coordinates of a third direction of the object based on a data acquired from a second sensor which is a different type from the first sensor.

Abstract: A method and apparatus for directly writing multimedia data onto a digital device are provided. The method includes sensing multimedia data written on a storage medium; displaying a user interface screen to display the multimedia data and a folder for a digital device; receiving a command to write the multimedia data in the folder; converting the multimedia data to a format which is playable by the digital device; and writing the converted data in the folder. The apparatus includes a sense unit which senses multimedia data written on a storage medium; a display unit which displays a user interface screen; an input unit which provides input in the form of a command to write the multimedia data in a folder; and a converting and writing unit which converts the multimedia data to a format which is playable by the digital device and writes the converted multimedia data in the folder.

Abstract: A system and method for providing an online community service is disclosed. The online community provision system includes a played-content information provision server, a client and a community server. The played-content information provision server provides played-content information about digital content. The client selects digital content through a user, requests played-content information about the selected digital content from the played-content information provision server, and receives the played-content information. The community server provides an online community service corresponding to user preferences based on the played-content information to the client at the request of the client.

Abstract: A method and apparatus for managing a sliding window in an IP security algorithm are provided. The method involves (a) determining whether or not a sliding window, used for determining whether or not a received IP packet is to be transmitted or abandoned, is full of IP packets; and (b) updating sequence numbers stored in the sliding window by adding a size of the sliding window to each of the sequence numbers if the sliding window is full of IP packets. Accordingly, a sliding window is updated by adding the size of the sliding window or a predetermined value to each sequence number stored in the sliding window irrespective of a sequence number of a received IP packet. Therefore, IP packets can be more stably transmitted by checking the sequence number of the received IP packet and abandoning the received IP packet if the sequence number of the received IP packet is not within a predetermined range.

Abstract: Disclosed in this invention is a use of an extract of the root of balloon-flower for preventing and treating a degenerative brain disease or for enhancing memory.

Abstract: A pharmaceutical composition comprising a lower alcohol-soluble extract of Ferula asafoedida L or a compound isolated therefrom including galbanic acid, karatavicinol, umbelliprenin, farnesiferol B, or farnesiferol C exhibits a potent anticancer activity.

Abstract: A combined stylus in which a mike and a wire/wireless interface are mounted, and a method for driving the combined stylus. The combined stylus transmits user's speech to a personal portable terminal in a wire/wireless manner with built-in mike and speaker in a transmission mode, records speech data that is input and plays back the speech data according to record and playback modes. A mike and a wire/wireless interface are mounted in a stylus, and thereby speech can be transmitted to a terminal without an additional input device while using the function of the stylus. In addition, after the speech is recorded in the stylus, the stored contents can be transmitted to the terminal via a communication module.
