Abstract: Provided are a hybrid supported catalyst which includes two or more kinds of transition metal compounds having the following Chemical Formulas 1 and 2, thereby preparing a polyolefin, particularly, a high-density polyethylene having a molecular structure which is optimized to improve tensile strength of a chlorinated polyolefin compound, and a method of preparing a polyolefin using the same: wherein all the variables are described herein.

Abstract: Provided is a method of operating a terminal. The method includes determining a profile item applicable to the profile view for the account based on an input received by the terminal and a coordinate indicating a position where the profile item is provided on the profile view. The method includes displaying the profile item on a screen of the terminal based on the determined profile item and the determined coordinate. The method includes receiving an input related to the profile item, and displaying a visual effect corresponding to the input on the screen.

Abstract: An aerosol generating system includes: a cavity configured to accommodate at least a portion of a cigarette; a first induction coil located around the cavity; a second induction coil located around the cavity and connected to the first induction coil in parallel; and a battery configured to supply an alternating current to the first induction coil and the second induction coil, wherein the first induction coil and the second induction coil have different resonant frequencies.

Abstract: A vector map display method executed by a user terminal device may include: a web vector map display viewpoint change step of changing a viewpoint of a web vector map according to the directions of previously stored first and second viewpoints; a background or POI information extraction step of extracting a background or one or more pieces of POI information corresponding to a current position of the user terminal device from data of the web vector map by reflecting the first and second viewpoints; a size ratio adjusting step of adjusting the size ratio of the extracted background or POI information; a current web vector map data generation step of generating data of the current web vector map corresponding to the current position; and a current web vector map display step of displaying the data of the current web vector map.

Abstract: A graphics-based web vector map display method may include: extracting object information from map sheet information of a previously stored original vector map; extracting an input array of a display engine for each type of the original vector map; storing the object information in the extracted input array of the display engine; separating the input array having the object information stored therein into property layer arrays according to property information of map information; storing the separated property layer arrays as map sheet information of a web-based vector map; and generating service-specific vector map information from the map sheet file of the web-based vector map.
