Abstract: A power converter having a Scott-T transformer includes a direct current to alternating current converter configured to have at least two multilevel converters converting input direct current power to alternating current power, a Scott-T transformer configured to operate in medium frequency of several hundreds of Hz to several tens of kHz, to transform a voltage level of the alternating current power from each of the at least two multilevel converters of the direct current to alternating current converter into three-phase alternating current power, and to output the three-phase alternating current power, and an alternating current to direct current converter configured to convert the three-phase alternating current power from the Scott-T transformer to direct current power.

Abstract: A method and an apparatus produce and reproduce Augmented Reality (AR) contents in a mobile terminal. In the method, contents are produced. An image including an object corresponding to the contents is recognized. Recognition information for the object corresponding to the contents is obtained based on a recognition result. AR contents including the contents and the recognition information are generated. Therefore, AR contents for an input image may be easily produced and reproduced, and the AR contents may be used as independent multimedia contents, not an auxiliary means of other contents.

Abstract: A method and an apparatus for controlling screen display in a portable terminal are provided. In the method, whether a screen touch occurs is determined. When the screen touch occurs, whether the screen touch corresponds to a spiral touch is determined using coordinates at which the screen is touched. When the screen touch is the spiral touch, the screen is magnified or reduced.

Abstract: An apparatus and method for providing a coupon service in a mobile communication system are provided. A method of operating a user terminal for providing a coupon service in a mobile communication system includes receiving coupon information of one or more shops that exist within a specified range around the user terminal from a Social Network Service (SNS) server, displaying the received coupon information, and generating a coupon by using the coupon information of the shop at the request of the coupon information, wherein the SNS server receives coupon information uploaded from a vendor terminal and Global Positioning System (GPS) information of a shop capable of using the coupon service.

Abstract: An apparatus and method display a world clock on the basis of an Augmented Reality (AR) scheme in a portable terminal. The method for displaying information in the portable terminal includes obtaining camera image data from a camera. The method also include searching for a city corresponding to a camera location and a camera viewpoint direction on the basis of a memory. The method further includes obtaining information on the found city and displaying the obtained information on the found city by compositing the information into the obtained camera image data.
