Abstract: The present invention relates to a composition for forming a composite polymer film, a method for preparing the composition for forming a composite polymer film, a composite polymer film and a method for preparing the composite polymer film. The composition for forming a composite polymer film comprises: a fluorine-based polymer solution comprising a fluorine-based polymer; and polyvinylidene fluoride nanoparticles dispersed in the fluorine-based polymer solution. The method for preparing the composition for forming a composite polymer film comprises the steps of: preparing a fluorine-based polymer solution comprising a fluorine-based polymer; and dispersing polyvinylidene fluoride nanoparticles in the fluorine-based polymer solution. The composite polymer film comprises: a polymer matrix formed from a fluorine-based polymer; and polyvinylidene fluoride nanoparticles dispersed in the polymer matrix.

Abstract: There is provided a method for providing driver's driving information of a user terminal device, including accessing a driving information providing server storing data generated in a driving recording device for a vehicle, receiving driving record data including event record data corresponding to a driving-related event of a driver from the driving information providing server, and displaying a driving-related event occurrence location on a map using the received driving record data. The driving-related event may include at least two or more of a lane departure event, a forward collision possibility event, a rear side collision possibility event, a sudden deceleration event, a sudden acceleration event, a sudden stop event, a sudden start event, and a speeding event.

Abstract: A method of reducing access time to a UTRAN in UMTS. Upon receipt of a preamble signature from a UE, the UTRAN determines whether the preamble signature is in current use. If the preamble signature corresponds to an available RACH, the UTRAN transmits a positive AICH to the UE. If the preamble signature corresponds to an RACH in current use, the UTRAN determines whether there is a signature corresponding to an available RACH. If all signatures are in use, the UTRAN transmits a negative AICH to the UE.

Abstract: A method and system for downlink channelization code allocation or assignment in a Universal Mobile Telecommunication System (UMTS) are presented. The method and system generate an optimal channelization or Orthogonal Variable Spreading Factor Orthogonal Variable Spreading Factor (OVSF) code to be assigned to a new channel through a route having the minimum influence while maintaining the existing or assigned OVSF codes. The inventive method and system leave reserved codes by managing generation and release of the OVSF codes. This prevents situations where the new channel cannot be assigned an OVSF code due to a lack of OVSF codes, even though there is enough available power and enough available channels.
