    Abstract: Example embodiments relate to a membrane, a method of manufacturing the same, and a composite membrane including the same. The membrane may include a polyacrylonitrile-based copolymer that includes a hydrophobic side chain and/or a hydrophobic repeating unit. The membrane may include a skin layer and a porous layer. A thickness ratio of the skin layer relative to the porous layer may be about 0.01 or less. The skin layer may have a thickness of about 1 μm or less. The membrane may have a relatively high water flux. When using the membrane, a water treatment module having higher energy efficiency may be achieved.

    Abstract: A fingerprint recognition method and system for recognizing a fingerprint by storing local fingerprint images inputted from a fingerprint sensor and compositing the stored local fingerprint images into an effective single fingerprint image. The method includes obtaining relative sliding speed and directional information between the local fingerprint images, correcting sliding speed and directional values of the local fingerprint images using the obtained sliding speed and directional information, and compositing the local fingerprint images into the effective single fingerprint image using the corrected sliding speed and directional values.
