Abstract: A privacy protection policy is present in a content sharing system. A method for managing contents in a content sharing system includes receiving a content download request from a first account through a first device; and determining whether to carry out the download by considering at least one of a sharing range of a download-requested content, a content access right of the first account, a content access right of an owner account of the first device, a sharing range of a download folder, and sharing acceptance or rejection of an owner of the content.

Abstract: A method for determining a source and a transmission path to provide content includes receiving a message comprising at least one of channel information of a link between a request device which requests content download and a central management device, available resource amount information of a candidate device, channel information of a link between the candidate device and the central management device, and channel information of a link between the request device and one candidate device. The method also includes determining a source device and the transmission path for providing the content to the request device using an available resource amount of the candidate device, a data rate of the link between the request device and the central management device, a data rate of the link between the request device and the candidate device, and a data rate of the link between the candidate device and the central management device.

Abstract: A cloud service system includes at least one user device, a plurality of clouds for providing different cloud services, and a gateway connected between the user device and the clouds. The gateway selects at least one of the clouds according to predefined Service Level Agreement (SLA) information, and stores content provided from the user device to the selected cloud.

Abstract: Provided are a method and apparatus for driving a PDP for widening a driving margin and improving contrast. The method for driving a PDP includes a first step of forming wall charges in cells with a set-up discharge using a set-up signal in a first sub-field and erasing the wall charges with a set-down discharge using a first set-down signal to initialize the cells, and a second step of erasing the wall charges with a set-down discharge generated using a second set-down signal different from the first set-down signal in a second sub-field, to initialize the cells. The method and apparatus for driving a PDP uniformly initialize sub-fields to widen the driving margin of PDP and remove a set-up discharge in at least one sub-field to improve the contrast of PDP.

Abstract: A composition with improved shelf life for filling small gaps in a semiconductor device is provided. The composition comprises an end-capped silicone polymer. The molecular weight of the end-capped silicone polymer is not varied during storage. In addition, the dissolution rate (DR) of the composition in an alkaline developing solution is maintained at a desired level during storage. That is, the composition is highly stable during storage. Therefore, the composition is suitable for use in a node separation process for the fabrication of a semiconductor capacitor.
