Abstract: The present invention relates to a method for preparing an inorganic compound using desulfurization gypsum for reducing greenhouse gas emissions, and, more specifically, to a method for preparing an inorganic compound, in which calcium sulfate and calcium carbonate, which have various uses as construction materials and the like, can be prepared using, as raw material, desulfurization gypsum which, being a recycled resource, is industrial waste, and an extraction agent, and the extraction agent can be reused after separation, and thus, compared to existing processes, greenhouse gases and manufacturing costs can be remarkably reduced.

Abstract: The present invention relates to a composition for detecting microbial contamination comprising a preparation for detecting nucleases, and a use thereof. A probe for measuring nucleic acid double-stranded nucleases, according to the present invention, may detect the comprehensive nucleic acid degradation capability of nucleases, whereby it is possible to quickly and precisely detect and quantify live microorganisms in a sample in a simple manner. Moreover, since the probe of the present invention is characterized in that signals of fluorescence consistently increase; is capable of measuring live microorganisms; and consists of a double-stranded nucleic acid, the probe is excellent for storage in a kit or a cartridge. As such, it is expected that the probe of the present invention may be used to easily and simply measure and compare the degree of contamination of microorganisms in an environment.

Abstract: A dish washer for commercial use is provided. The dishwasher according to current application is used for restaurants, hospital, school and military camp, etc. The dish washer of the current application has an auxiliary rinsing water pipe that is embedded inside of a washing water pipe. The rinsing water supplied to the washing water pipe drives the remaining soapy washing water out of an upper washing water impellor just after the washing step is finished. In rinsing step, rinsing water is supplied to an upper rinsing impellor via main rinsing water pipe. Rinsing water is sprayed to the bottom of the washing water impellor to remove the residual soapy washing water droplets. The dish washer of the current application removes a chance of contamination of dishes and cups by soapy washing water drops after washing is finished.

Abstract: The present invention provides a microfluidic device, comprising: a substrate; a sample solution inlet provided on the substrate for introducing a sample solution; a washing solution inlet provided on the substrate for introducing a washing solution; a washing valve provided on the substrate at which the sample solution and the washing solution stops and in which passive washing is induced by pressure difference between the sample solution inlet and the washing solution inlet when the sample solution and the washing solution join together; and a plurality of channels connecting the sample solution inlet and the washing solution inlet to the washing valve, within which channels the sample solution and the washing solution can move by capillary force.
