Abstract: A navigation system for downloading adjacent position information of a current user position using a wireless network to display the downloaded information on a screen and method thereof are provided. The method includes the steps of: setting a starting point, a destination, and specific information to be displayed on a screen; calculating a current user position based on position information received from a wireless network and identification (ID) information; displaying a user movement based on information stored in a database, or, alternatively, requesting a server to send specific information about the adjacent position which is set in the setting step; and downloading only the specific information to display the downloaded result on a screen while displaying a user movement on the corresponding screen. According to the navigation system and method thereof, only necessary information about the adjacent position is downloaded, thereby improving the efficiency of the navigation system.

Abstract: The present invention discloses a method for fabricating a semiconductor device using an etch-resistant polymer. The method includes a step for the in-situ generation of a polymer layer on the exposed surfaces of a photoresist film pattern, a pad oxide film, and a hard mask layer. This polymer acts as a protective film and prevents photoresist erosion during trench etching processes and improves the etch selectivity. As a result, trench structures can be formed more easily and with improved dimensional control.

Abstract: A method for displaying a current position of a moving object such that the indication of the moving object when the moving object is positioned above ground is different from that when the moving object is positioned under ground. The method includes the steps of detecting information about the current position of the moving object obtained from a plurality of satellites included in a global positioning system and detecting data about an azimuth angle of the moving object and a speed of the moving object, analyzing whether the moving object is positioned above ground or under ground, based on the detected information, and displaying the current position of the moving object based on the result of the analysis in such a manner that an indication of the current position of the moving object when the moving object is positioned on the ground is different from that when the moving object is positioned under ground.
