Abstract: A curtain integrated door regulator structure includes a motor, a drive gear, a drum retainer, a glass driving drum, a curtain driving drum, gear keys and key grooves. The motor generates a rotational driving force to rotate a driving shaft. The drive gear has a shaft receiving hole into which a driving shaft of the motor is fitted. The drum retainer has a spiral groove shaft supporting part spirally coupled to a spiral protrusion disposed on an outer circumference of the drive gear. The glass driving drum and the curtain driving drum are rotatably received in the drum retainer and disposed at an outer side of the drive gear. The gear keys are disposed on the outer circumference of the drive gear. The key grooves are formed in the glass driving drum and the curtain driving drum, respectively, and have a shape corresponding to that of the gear keys.

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.

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.

Abstract: Provided is an apparatus for concurrently detecting a defect occurring in a heat exchanger tube and a geometric transition of the heat exchanger tube. The apparatus for detecting the state of a heat exchanger tube, including: the first detection unit detecting a defect of the heat exchanger tube; and the second detection unit detecting a geometric transition of the heat exchanger tube, in which the first detection unit and the second detection unit are disposed at the same circumferential position of a cylindrical body separately, installed to have a certain distance in the lengthwise direction of the cylindrical body, and inserted inside the heat exchanger tube. According to the present invention, not only a defect but also the type of geometric transition, which may accelerate the initiation and growth of a defect, is identified and the size of the geometric transition is concurrently measured, thereby improving the reliability in early detection of a defect.

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.

Abstract: The present invention relates to an accounting information processing method using a wireless communication network, and in particular to an accounting information process method using a wired communication network which is capable of classifying an accounting information input work into a work which may need an accounting knowledge and a work which may be performed without an accounting knowledge and is capable of implementing an accounting information generation work based on the internet by a plurality of part time workers who do not have an accounting knowledge with respect to an accounting information input work or who are capable of performing an accounting work at home.

Abstract: Disclosed herein is a method of discriminating a through-wall crack and measuring the through-wall length of the crack in a steam generator tube of a nuclear power plant. The method of the present invention is characterized in that the through-wall crack is discriminated and the through-wall length of the crack is measured in such a way that there are measured the number and positions of inflection points of a graph that is plotted by relating characteristic amplitude values of eddy current signals, which are generated whenever a coil of a motorized rotating probe passes the crack while being spirally rotated, to the positions in the length of the crack.
