Abstract: This application describes a method, a device, and a computer readable recording medium for maintaining meta information of a secure document. The method may be performed by identifying a reading target document and acquiring information of the reading target document, identifying a window of a program where the reading target document is read and acquiring information of the window, mapping information of the reading target document and information of the window by using a regular expression for the program, mapping meta information of a secure document and the reading target document based on information of the reading target document and mapping meta information of the secure document mapped to the reading target document to a new document created from the reading target document.

Abstract: The present disclosure relates to a method for managing an object, an apparatus for the same, a computer program for the same, and a recording medium storing computer program thereof. A method for managing an object using a trace-identifier ID) according to the present disclosure may comprise: updating T-ID information for the object at a timepoint at which the object is saved after the object is opened at an endpoint; writing the updated T-ID information as metadata of the object; and transmitting the metadata including the T-ID information to a server.

Abstract: A soil remediation facility includes a first screen apparatus including a vibratory screen, a drum mixer apparatus mixing the contaminated soil with a diluent, a saturated steam and hot water, a scrubbing apparatus including a mixing container and an impeller, a second screen apparatus including a vibratory screen. The facility further includes a floatation apparatus which adds a chemical agent for generating bubbles to the soil mixture, injects an air into the soil mixture to desorb contaminants from the soil mixture, and separates the desorbed contaminants by causing the desorbed contaminants to float. The facility further includes a hydro-cyclone apparatus which swirls substances contained in the soil mixture to sort the substances depending on a particle size and a desilter which swirls substances in the soil mixture at a higher angular velocity than an angular velocity in the hydro-cyclone apparatus to sort the substances.
