Abstract: An implementation relates to a polyester-based film having low hygroscopicity, a manufacturing method therefor, and a membrane electrode assembly comprising same, and the polyester-based film has excellent flexibility, adhesion and durability and has a moisture absorption represented by formula 1, which meets 0.25% or less, and thus has excellent hydrolysis resistance so as to be applied as a film for a fuel cell sub-gasket and exhibit excellent characteristics.

Abstract: Disclosed herein are a fixed mobile convergence (FMC) apparatus and a method for searching an access point. The FMC apparatus and method effectively search an access point using a frequency searching method of a radio access technology (RAT) service in which a discontinuous reception (DRX) operation is used to increase efficiency in power consumption of the FMC apparatus. The FMC apparatus recognizes an area available for a wireless local area network (WLAN) service and may automatically search an access point in the corresponding area so that it is possible to decrease inconvenience to a user.

Abstract: There is provided a WORM type organic optical recording media comprising a recording layer, a reflective layer and a protective layer which are formed in sequence on a substrate, the recording layer consisting of near infrared absorbing dye able to absorb a laser beam and to generate heat and of a thermosetting or photocuring resin. The organic optical recording medium can be prevented from being rewritten by heating up to 50.degree. C. or irradiating with a UV light, said dye being capable of absorbing near infrared rays and generating heat.The medium exhibits stable reading characteristics of at least 45 dB even after irradiating with a light with a short wavelength. In addition, it also has a function of record locking by curing the resin of the recording layer, so that, once recorded, rewrite or additional recording is not allowed therein.
