    Abstract: Provided are a dendrimer solid acid and a polymer electrolyte membrane using the same. The polymer electrolyte membrane includes a macromolecule of a dendrimer solid acid having ionically conductive terminal groups at the surface thereof and a minimum amount of ionically conductive terminal groups required for ionic conduction, thus suppressing swelling and allowing a uniform distribution of the dendrimer solid acid, thereby improving ionic conductivity. Since the number of ionically conductive terminal groups in the polymer electrolyte membrane is minimized and the polymer matrix in which swelling is suppressed is used, methanol crossover and difficulties of outflow due to a large volume may be reduced, and a macromolecule of the dendrimer solid acid having the ionically conductive terminal groups on the surface thereof is uniformly distributed. Accordingly, ionic conductivity is high and thus, the polymer electrolyte membrane shows good ionic conductivity even in non-humidified conditions.

    Abstract: An oligomer solid acid and a polymer electrolyte membrane using the same. The polymer electrolyte membrane includes a macromolecule of oligomer solid acid having an ionically conductive terminal group at its terminal end and the minimum amount of ionically conductive terminal groups required for ion conduction, thus suppressing swelling and allowing a uniform distribution of the oligomer solid acid, thereby improving ionic conductivity. Since the number of ionically conductive terminal groups in the polymer electrolyte membrane is minimized and the polymer matrix in which swelling is suppressed is used, methanol crossover and difficulties of outflow due to a large volume are minimized, and a macromolecule of the oligomer solid acid having the ionically conductive terminal groups on the surface thereof is uniformly distributed. Accordingly, ionic conductivity is high and thus, the polymer electrolyte membrane shows good ionic conductivity even in low humidity conditions.

    Abstract: An apparatus for coding keys of graphic animation data and a method thereof are provided. The coding apparatus for encoding key data corresponding to time variables among graphic animation comprises a quantizer which quantizes the key data and generates quantized data; a differential pulse code modulation (DPCM) processing unit which DPCM processes the quantized data, receives the DPCM processed data, and by repeatedly performing DPCM processing, selects and outputs DPCM data having the lowest dispersion among N-th order DPCM data generated in the DPCM processing; a polar value removing unit which reduces the range of data by removing a polar value in the DPCM data output form the DPCM processing unit; and an entropy encoder which removes the redundancy of binary bits in the data output from the polar value removing unit and generates a compressed and encoded binary bit stream. In the method, by selecting a code where data dispersion is the lowest according to the characteristic of key data to be coded, redundancy of data to be coded increases such that coding efficiency increases. Also, by removing polar values appearing after DPCM, the coding efficiency increases.
