Abstract:
PURPOSE: A refrigerator for Korean beef is provided to store Korean beef for a long time by allowing ultraviolet lamps to properly irradiate the Korean beef with ultraviolet rays. CONSTITUTION: A refrigerator for Korean beef comprises a loading frame(2), loading shelves(2a), ultraviolet lamps(3), and a controller(5). The loading frame is installed inside a main body. The loading shelves are installed in the loading frame. The ultraviolet lamps are installed in both sides of the rear surface of the loading frame. The controller has a PCB(printed circuit board) and a control panel. The control panel is connected to the PCB and is installed on the front surface of the main body.

PURPOSE: A method and a device for determining a heading angle of a wireless LAN are provided to prevent the accumulation of PDR position errors by using a heading angle detecting algorithm based on a wireless LAN even in a GPS shadow region and to accurately determine the information of a user position. CONSTITUTION: A device for determining a heading angle of a wireless LAN comprises modems(710,715), a control unit(720), and a memory unit(730). The modems perform communication with other nods. The control unit test whether the rotation of a user is sensed or not by using the modems. A moving direction vector is obtained when sensing the rotation of the user, and the heading angle is obtained by using the obtained moving direction vector. The memory unit records signal intensity according to distances to reference points and signal intensity according to a distance to an AP.

Abstract:
알코올 발효저해물에 대한 저항성을 증대시키는 단리된 폴리뉴클레오티드, 이를 포함하는 벡터, 알코올 생산성 균주 및 이를 이용한 알코올의 생산방법에 관한 기술로서, 특정한 단리된 폴리뉴클레오티드가 호스트셀 내에서 과발현됨으로써 호스트셀의 알코올 발효저해물에 대한 저항성이 증대되므로 알코올 발효시 생산성이 증대될 수 있다.
Abstract:
PURPOSE: An apparatus and method for detecting location information using a navigation algorithm like radio navigation and walking navigation are provided to accurately identify the location information of a user even in an environment in which a car navigation system is unable to provide the location information of the user. CONSTITUTION: An apparatus for detecting location information comprises an UI(User Interface), a GPS(Global Positioning System) receiving unit(103), and a navigation algorithm control unit. The UI interfaces with a user. The GPS receiving unit searches around a GPS satellite and receives pseudo range information from at least one of searched GPS satellites. The navigation algorithm control unit calculates the displacement of a pedestrian terminal based on detected steps of a pedestrian and corrects the displacement of the pedestrian terminal calculated by using the received pseudo range information. The navigation algorithm control unit measures the location of the pedestrian terminal by using a corrected value.
