  • Publication number: 20150141532
    Abstract: Provided are a solvent-substitution solvent for producing a hydrophobized aerogel and a method for producing a hydrophobized aerogel. The solvent-substitution solvent includes pentanol in an amount of 41 wt % to 100 wt % and n-butanol in an amount of 0 wt % to 59 wt %. The method includes performing a solvent substitution process using the solvent-substitution solvent. If the solvent-substitution solvent is used for solvent substitution and/or hydrophobization in an aerogel production process, water (moisture) contained in a wet gel may be effectively substituted with the solvent-substitution solvent, and the solvent-substitution solvent may easily be collected at a high degree of purity and may be reused if necessary. Therefore, the rate of solvent loss may be minimized.

  • Publication number: 20100290415
    Abstract: A transmission delay caused by a Bandwidth Request (BR) of a Mobile Station (MS) in a broadband wireless communication system can be avoided. An operation of the MS includes performing an initial BR to allocate resources across a plurality of frames. When a resource is allocated according to the initial BR, an adaptive BR is performed on the resource in a piggyback manner by using the resource while transmitting an acknowledge (ACK) message corresponding downlink Transmission Control Protocol (TCP) data.

  • Publication number: 20080097003
    Abstract: Disclosed herein is a method for preparing a food packaging film containing chitosan comprising 90.0 to 98.0% by weight of polyethylene resin and 2.0 to 10.0% by weight of a premix containing chitosan, in which the premix comprises fine flakes of polyethylene film and chitosan powder in a ratio of 80.0 to 99.5% by weight: 0.5 to 20.0% by weight. According to the method, in order to evenly disperse and distribute chitosan in the food packaging film, chitosan powder is previously mixed with synthetic resin film flakes to prepare a premix. The premix is mixed with a synthetic resin in a predetermined ratio and extruded to prepare the food packaging film. As a result, it is possible to industrially mass-produce the food packaging film, which has chitosan powder particles evenly dispersed and distributed therein and maintain excellent elongation and tensile strength.

  • Publication number: 20060159015
    Abstract: A method and apparatus is provided for transmitting data in a broadband wireless access communication system. If transmission data is generated, a data packet generator sets information corresponding to a service type of the generated data in a predetermined field of the generated data. A data packet parser parses the set information, and quality-of-service determiner determines a quality-of-service of the data set in the predetermined field according to the parsing result. A data mapper maps the data to transmission traffic according to the determined quality-of-service before transmission.
