Abstract:
PURPOSE: In case a user terminal has no within a transmission range of a base station in multimedia data transmission, a multimedia broadcasting service providing device in a mobile network and a method thereof are provided to improve QoS by blocking multimedia data transmission. CONSTITUTION: In case a user terminal has no within a transmission range of a base station, if a new user terminal enters into the transmission range with hand over, a service start decision unit(350) outputs a service start command about a broadcasting service. In order to transmit multimedia data to the new user terminal through a broadcast channel, a data transfer unit(320) offers the multimedia data from a data receiver(310) to a data transmission part(330).

PURPOSE: A P2P service providing device, a method and a recording medium for executing a data exchanging method within a peer node consisting of a P2P network in a computer are provided to perform an efficient data exchange by acquiring necessary data rapidly. CONSTITUTION: A plural peer nodes consisting of a P2P network offers receiving object data. A node information storage(110) stores information about the receiving object data in a peer node information table corresponding to an identification number of each peer node. The peer nodes are classified based on a data amount of the receiving object data which each peer node holds. A node group forming unit(120) forms a node group. A group information providing unit(130) offers group information about the node group which the other peer nodes belongs to each peer node.

Abstract:
A gas sensor and a manufacturing method thereof are provided to manufacture a gas sensor using a nano material, such as nano tube and nano wire, in large quantities. A gas sensor using a nano material includes a semiconductor substrate(100), a heater electrode(130), an insulation layer(140), a sensor electrode(150), a detection portion(160), and an upper portion protective layer(170). The semiconductor substrate consists of a silicon oxide layer(110) and a silicon nitride layer(120) which are deposited in sequence. The heater electrode is formed on the silicon nitride film and consists of heater arrays in the IDE(InterDigitated Electrode) pattern. The insulation layer is formed on the heater electrode except an electrode terminal portion. The sensor electrode is formed on the insulation layer and consists of sensor arrays in the IDE pattern. The detection portion is formed on the sensor electrode and is distributed to electrically contact the sensor electrode through a nano tube or a nano wire. The upper portion protective layer is laminated on a portion except the detection portion and the electrode terminal portion.
