    摘要: A method for setting digital rights associated with content the method includes receiving a request from a user to access content comprising digital rights defined by a first set of attributes, identifying if the user has existing digital rights to the content, wherein the existing digital rights is defined by a second set of attributes, and modifying the existing digital rights associated with the content to include the first set of attributes. A terminal for issuing digital rights includes a digital rights management (DRM) server for issuing a rights object to a terminal or a content server; and a content server for encoding content using encryption keys issued from the DRM server and providing encoded content to the terminal in response to a content download request wherein the DRM server also issues content encryption keys to the content server.

    摘要: A process is disclosed for preparing N,N'-disubstituted urea by reacting an amine and CO/O.sub.2 mixture gas in the presence of a catalyst system comprising at least one selenium compound selected from SeO.sub.2, (CH.sub.3 O)Se(O)(OH) and (CH.sub.3 CH.sub.2 O)Se(O)(OH), and M.sub.2 CO.sub.3 (M=alkali metal) as a co-catalyst. The process enables less active aromatic amine with a low reactivity as well as an aliphatic amine to be easily transformed into disubstituted urea avoiding the use of expensive precious metal catalysts.

    摘要: There are provided an ionic liquid having ether group(s) in which a copper(I) compound is included, a method for preparing the same, and a method for removing traces amounts of acetylene-based hydrocarbon compounds included in olefin by absorption or extraction using the same. When the disclosed solution is used, oxidation of Cu(I) to Cu(II) is prevented since CuX is stabilized by the ionic liquid. Thus, selective removal efficiency of acetylenic compounds is improved greatly while the removal performance is retained for a long period of time. Further, since the solution according to the present disclosure is applicable as an extractant as well as an absorbent, the associated operation is simple and apparatus cost can be decreased.
