    Abstract: PURPOSE: A titanium oxide nanotube material and a manufacturing method thereof are provided to improve electro-optical characteristic by arranging surface or direction of a tetragonal crystal system as a preferred direction. CONSTITUTION: A titanium oxide nanotube material has a crystal structure which is aligned in direction of a tetragonal crystal system as a preferred direction. Full width at half maximum of the rocking curve for surface peak of XRD data(004) is 11.1-20.3 degrees. A manufacturing method of the titanium oxide nanotube material comprises the following steps: preparing electrolyte having the moisture content of 1.5-2.5 wt%; dipping a titanium substrate in a vessel in which electrolyte is put; growing the titanium oxide nanotube on the titanium substrate by processing anodizing; desiccating the titanium substrate by washing; and crystallizing the titanium oxide nanotube by heat-treating the desiccated titanium substrate.

    Abstract: An umbrella for a wheelchair comprises an operating unit; an expansion unit; and an umbrella unit. The operating unit is fixed on the arm of a wheelchair to be rotatable. The expansion unit is fixed on the back of the wheelchair and extends to the upper side of a wheelchair user. At the end of the extension unit, a rotating unit which rotates in the same direction of the operation by the operating unit is fixed. The umbrella unit blocks rain by being fixed on the rotating unit to be detachable.

    Abstract: PURPOSE: A video encoder, a video decoder, a video encoding method, and a video decoding method perform a video decoding by distinguishing a reliable channel. CONSTITUTION: A first encoding unit (100) outputs a generated syndrome bit by channel-encoding a DC conversion factor of a first frame of a video sequence. The first encoding unit selectively channel-encodes the quantized AC conversion factor of the first frame according to channel information between a video encoder and a video decoder. A second encoding unit (200) intra-encodes the key frame of the video sequence. A frame controller (300) outputs the first frame to the second encoding unit or outputs the first frame to the first encoding unit according to the channel information.
