Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

Abstract: A method and an apparatus for performing transmission power selection of a wireless access device and channel allocation in a combination manner, for resource management optimized for a wireless network environment supporting multimedia traffic are provided. In a method for managing a radio resource of at least one Access Point (AP) in a wireless communication network, a transmission power select operation for the AP is performed on each of a plurality of channel settings, and a network performance value is predicted. Optimized channel setting is selected among the plurality of channel settings depending on the predicted network performance value. The optimized channel setting and optimized transmission power corresponding to the optimized channel setting are allocated to the AP.

Abstract: A signal link selection method between exchange systems having a plurality of signal links of a destination exchange comprises the steps of obtaining a total number of signal links and a total link list, obtaining a number of unavailable signal links, obtaining a total number of available links by subtracting the number of unavailable links from the total link number, obtaining a first link number comprising a remainder obtained by dividing a signal link selection (SLS) value of a signal message (i.e., the decimal (numerical) equivalent of the binary code for the signal message) by the total link number, checking whether the first link is available, selecting the first link if it is available, and outputting a message. If the first link is not available, the method further comprises the steps of obtaining a second link number comprising a remainder obtained by dividing the first link number by the total number of available links, selecting the second link, and outputting a message.
