Abstract: A method of detecting mobile security file leakage of the present disclosure includes receiving, by a detection server, an operating system type from a mobile device, connecting, by the detection server, to the mobile device depending on an operating system to load a media file system, checking an analysis setting time by the detection server connected to the mobile device, analyzing, by the detection server, the media file system to detect presence or absence of an abnormality, generating, by the detection server, an analysis result based on presence or absence of an abnormality, checking whether there is an error in the analysis result and extracting an original file and a thumbnail file if there is no error by the detection server, deleting, by the detection server, a file from which an abnormality is detected based on the analysis result, and generating and storing a result report on the analysis result by the detection server, wherein the operating system type is at least one of a first operating system

Abstract: The present invention provides a polyurethane foam and a manufacturing method therefor, the polyurethane foam being a reaction product of a polyester polyol and an isocyanate and having a flame retardancy index (FRI) of 130 or less, wherein the polyester polyol is formed from a composition comprising an alcohol and two or more types of aromatic carboxylic acid including isophthalic acid and phthalic acid. The polyurethane foam can have both improved flame retardancy and heat resistance, and has total heat release and total smoke release that are significantly lower than those of a conventional polyurethane foam, and thus has an excellent fire protection effect when used as an interior material for buildings and low toxic gas generation.

Abstract: The present invention relates to a method of manufacturing a mat containing aerogel and to a mat manufactured using this method. A method of manufacturing a mat containing silica aerogel according to an aspect of the invention includes: (S1) producing a wet gel by mixing water glass and alcohol in a reactor; (S2) modifying a surface of the wet gel by adding an organic silane compound and an organic solvent to the reactor and mixing; (S3) separating a upper liquid from a solution in the reactor and impregnating a fibrous matrix with the upper liquid; and (S4) drying the fibrous matrix impregnated with the upper liquid. According to an aspect of the invention, a mat containing silica aerogel can be manufactured using only water glass as raw material, even when applying the drying process in an ambient environment, without using expensive materials or supercritical apparatus.
