摘要： The present invention relates to a method for manufacturing a transition metal-carbon nanotube hybrid material using nitrogen as a medium. The present invention is characterized in that nitrogen-added carbon nanotube is grown in the presence of metal catalyst particles by reacting an hydrocarbon gas with a nitrogen gas by a chemical vapor deposition (CVD) and a transition metal-carbon nanotube hybrid material where a transition metal is uniformly attached to the entire carbon nanotube structure in which nitrogen with a great chemical reactivity is added as heterogeneous elements is chemically manufactured. Therefore, the present invention does not use an acid treatment required to attach transition-metal atoms to the carbon-nanotube, a surface treating process using a surfactant and the like and an inhibitor for preventing the coagulation of the transition metal so that a simplification of the process is obtained and the method is an environment-friendly method. The transition metal-carbon nanotube hybrid material manufactured by the above can be applied variously as a hydrogen storage material, a catalyst material, an electric field emission device and an electrode material.

摘要： The present invention provides a network-based location measurement method using a pCELL database, comprising the steps of establishing a pCELL database in which a location measurement service target area is divided into lattices each having a predetermined size; continuously determining whether a request for location measurement occurs by a service subscriber; and, when the request for location measurement is generated, comparing fundamental information received from a mobile terminal with the pCELL database, determining a matching pCELL, and reporting the pCELL to the service requester. Furthermore, the present invention is constructed to periodically update a initially established pCELL database using the results of A-GPS-based location measurement and reflect variation in BTSs within a mobile communication network to the pCELL database, thereby always maintaining the optimal databae. The present invention contributes to the activation of location-based services by resolving problems related to stability of location measurement due to relays, and the degrading of accuracy of location measurement in a network-based location measurement method in a mobile communication system. Furthermore, the present invention improves the service usage rate of indoor subscribers, occupying about 70% of overall location measurement attempts and service quality and minimizes the need for human and physical resources upon initial commercialization and optimization by resolving the problem due to the considerable amount of human and physical resources required upon initial commercialization and optimization. Therefore, it is possible to replace A-GPS-based location measurement with relatively small costs.
