A portable computing apparatus and a processing method using the same, the portable computing apparatus including a management module and a processing module, wherein the management module provides a predetermined function list to a sub-display module when a specific event occurs, and the processing module processes a function selected from the function list by a user. Each of the combustible flakes 1 comprises a fibrous, carbon containing substrate on to which has been vapor deposited on one or both faces thereof a combustible material layer which is capable, in use, of igniting substantially simultaneously the entire surface onto which it is deposited. The entities can be Social Networking Sites, device, and contact groups in the device, contact groups in the SNS, content hosting servers or the like. The first electrode is formed on the same planar side of the first conductive type semiconductor layer as the second electrode, and is disposed in the same direction as the pad electrode with respect to the ohmically connected region. The present invention provides live information selection and analysis and provides basic functionality of crawling, indexing and summarizing chat room data, as well as generating messages, such as advertisements, responsive to the subject matter of the communication. The coordinate locations of the plurality of reconstructed pixels are adjusted based on the gantry tilt angle and used to form a reconstructed image.
