Abstract: A method and apparatus for synchronization of contents in a cloud service system for a mobile environment is provided. The synchronization method of a cloud service system includes uploading, at a device when data is changed, the changed data to a server, processing, at the server, the uploaded data, storing, at the server, the processed data along with a time change, transmitting, at the device, a synchronization request signal including a most recent server connection time at a predetermined time, downloading, at the device, a data log on data changed between the most recent server connection time and the current time, synchronizing, at the device, the data based on the data log, and updating the most recent server connection time.

Abstract: The present invention relates to a method of analyzing a protein or proteins comprising the steps of: (A) pre-treating a mixture containing at least one protein to obtain peptides; (B) obtaining information about retention times and mass values of the obtained peptides by performing data-independent analysis; (C) searching a first database on the basis of the information obtained in step (B) to quantify and qualify a target protein or proteins; (D) extracting information about the quantified and qualified target protein or proteins; (E) obtaining information about retention times and mass values by performing data-dependent analysis from the extracted information of step (D); (F) searching a second database on the basis of the information obtained in step (E) to further quantify and qualify the target protein or proteins; and (G) comparing the search results of step (C) and (F) to verify the quantification and qualification.
