Abstract: The present invention relates to a method for removing water from swollen superabsorbent polymers in a gel state, and a method for recycling sanitary absorbent articles using the same. According to the method of the present invention, water is removed from swollen superabsorbent polymers by immersing swollen superabsorbent polymers in a gel state into a composition wherein sea water that is readily available and calcium chloride that is readily available at low cost are mixed for a specified period of time. The method makes it possible to easily and economically remove water from swollen SAPs in a gel state. Thus, the method provides an economical and environmentally-friendly means for recycling sanitary absorbent articles comprising an absorbent that consists of SAP and cellulose pulp, after being used for absorbing human waste.

Abstract: A method and apparatus for supporting a hibernation function in a mobile device are provided. In the method, the mobile device detects a wakeup event in a hibernation mode and, in response to the wakeup event, loads a snapshot image into a volatile memory from a snapshot image region of a nonvolatile memory. After the loading of the snapshot image, the mobile device determines whether there is a system status has been modified. If the system status has not been modified, the mobile device finishes a system boot. If the system status has been modified, the mobile device performs data synchronization and then finishes the system boot.
