Abstract: A method used by an electronic device receiving a geo-fence service, determines whether a current position of the electronic device, determined using a cellular positioning system (CPS), is located within a first distance from a central point of a geo-fence service area. In response to determining that the current position is located within the first distance, the current position is determined using a Wi-Fi positioning system (WPS) and it is further determined whether the WPS determined current position is located within a second distance from the central point of the geo-fence service area. In response to the determination the current position is located within the second distance, it is determined whether the current position calculated using a global positioning system (GPS), is located within a boundary of a geo-fence service area.

Abstract: A method of detecting a region having a specific shape in a camera is provided. The method includes processing input image data in a camera and detecting the region having the specific shape. The method includes calculating gradation differences between a central pixel and respective peripheral pixels in each of local regions of an image frame, comparing an average gradation difference with each of the gradation differences and obtaining local gradient pattern (LGP) values based on a comparison result in each of the local regions, and detecting the region having the specific shape from the image frame using the LGP values obtained from the respective local regions.

Abstract: Techniques for assisting a designer in correcting discrepancies identified in layout design data. A user interface may be provided listing identified shorts and relevant information related to those shorts. Still further, the user interface may allow a designer to selectively choose a subset of the identified shorts, and to designate or otherwise provide correction data for use to correct the shorts before performing a short isolation process on the selected shorts. Alternately or additionally a user interface may provide a designer with graphical images showing the correction that should be made by a designer to address an identified discrepancy in layout design data.

Network interfaces of the first device and the second device are configured in accordance with the program and the messages exchanged between the first device and the second device. The Internet connection of at least one of the first device and the second device is shared based on the configured network interfaces.

Abstract: Disclosed is a coordination polymer crystal with porous metal-organic frameworks (MOFs), in which, while a crystal state of the coordination polymer crystal is maintained, an additional material selected from the group consisting of an organic compound, a metal cluster, and an organometallic compound is chemically bonded to the coordination polymer crystal. Therefore it is possible easily adsorb and store more guest molecules regardless of a change in an ambient temperature or pressure due to the chemically bonded additional material.
