Abstract: PURPOSE: An ammonum rhenate manufacturing method is provided to collect rhenium in an ammonium rhenate form which is used as a rhenium source from gas generated from the concentrate calcination of a rhenium containing aqueous solution and/or waste molydenite. CONSTITUTION: An ammonium rhenate production system(10) comprises a wet scrubbing unit(400), a sulfate ion removing unit(500), a solvent extraction unit(100), a precipitation unit(200), and a residual liquid treatment unit(300). The solvent extraction unit collects rhenium ions in a rhenium containing aqueous solution with an organic solvent, and reverse-extracts the rhenium ions into ammonia by treating the organic solvent with the ammonia. The precipitation unit precipitates the rhenium ions in an ammonium rhenate form from the rhenium ion containing ammonia. The residual liquid treatment unit evaporate-crystallizes the residual solution after separating the precipitated ammonium rhenate into solid and liquid, and precipitates the rhenium ions in the ammonium rhenate form by re-dissolving the obtained crystal in ammonia.

Abstract: A method and a device for setting up a security policy for a secure OS(Operating System) are provided to remove complexity by reducing the number of types and rules remarkably based on comparison with a usual SELinux(Security Enhanced Linux) security policy setting mode, and enable a user having no specialize knowledge to set up or control the desired security policy easily. An SELinux security policy template(51) comprises a form for setting up a subject, an object, and a subject's right for the object. A converting module(52) converts the security policy template into a TE(Type Enforcement) security policy(53) applicable to SELinux. The security policy includes a subject element defining the subject accessing the object, an object element defining the object accessed by the defined subject, a right element defining an access authority between the defined object and subject, and a transition element defining domain transition. The converting module includes a parser(521) parsing the security policy template, and a generator(522) generating more than one of a subject domain, the domain transition, an object type, and a TE operation from the parsed data, and generating TE context by combining the same.
