Abstract: A method of manufacturing a multilayer electronic component includes cutting a stack, in which internal electrode patterns and ceramic green sheets are alternately stacked in a stacking direction, to obtain unit chips and attaching a portion of a ceramic green sheet for a side margin portion to the unit chips in a direction, different from the stacking direction. The attaching includes attaching the portion of the ceramic green sheet to the unit chips by compression between a first elastic body on which the ceramic green sheet is disposed and the unit chips. The first elastic body includes a first elastic layer having and a second elastic layer having an elastic modulus different from the first elastic layer, and disposed between the unit chips and the first elastic layer. An elastic modulus of the first elastic body is greater than 50 MPa and less than or equal to 1000 MPa.

Abstract: A proxy server for uploading a file according to an embodiment of the present disclosure improves the upload speed of a file and to minimize upload delay due to the occurrence of an error in the upload process. Due to the fact that the upload of the upload target file is started by the client delivering only one HTTP request to the proxy server to start the upload of the upload target file instead of requesting an upload link for each divided chunk to the backend server and receiving the response message from the backend server, a transaction over a network having a relatively slow communication speed can be minimized and the upload speed can be improved accordingly.

Abstract: A method for managing contents shared by a Social Network Service (SNS), executed by a cloud server which is associated with an account of the SNS. It is detected whether a first content has been newly uploaded to the SNS or whether a metadata related to the first content previously uploaded to the SNS has been newly added. A second content corresponding to the first content is searched. The cloud storage is updated by linking context information related to the first content to the second content corresponding to the first content. The cloud server interworks with an account of the SNS of each user's individual to link context information of content shared on the SNS with the content stored in the personal cloud storage, thereby enabling easier update of the cloud storage. A user may easily search for desired contents using the context information.

Abstract: In a synchronization system including a local terminal, latest metadata of a file in a local storage and latest metadata of a file in the server storage are managed in a first tree database, which is a virtual database in a local terminal, and each of the local terminals is allowed to upload or download a changed file on the basis of the metadata in the first tree database so that a conflict that may occur due to multiple users simultaneously changing files can be minimized.

Abstract: A method for uploading and downloading file includes receiving, by a request receiver of the server, an upload request of a file from a first user terminal; transmitting, by the request receiver, a location information of a storage for storing the file to the first user terminal, verifying, by an upload confirmer of the server, whether the file is uploaded to the storage by the first user terminal, and storing, by a DB manager of the server, a metadata of the file including the location information in a metadata database (DB) when the file is uploaded to the storage by the first user terminal. A user may directly upload/download a file to/from the storage through the user terminal, and in this case, even if the number of users is increased, the server may not directly upload/download the file, thereby minimizing load burden of the server.

Abstract: Disclosed is a synchronization method of a cloud file system that enables a portable terminal to not consume excessive amount of battery power for data synchronization with the portable terminal such as a smart phone, enables a portable terminal and a stationary user terminal such as a personal computer to upload and download data in an appropriate time, and prevents time delay caused by the excessive traffic, during the data synchronization.
