Abstract: The present disclosure relates to a non-alcoholic fatty liver artificial tissue model. As compared to a conventional technology by which tissues are cultured only in Matrigel including a device composed of a decellularized liver tissue-derived extracellular matrix and a plurality of microchannels or a decellularized liver tissue-derived extracellular matrix, the present disclosure enables better mimicking of an actual non-alcoholic fatty liver disease due to the presence of Kupffer cells and hepatic stellate cells. Also, according to the present disclosure, the growth of liver organoids can be improved and fat accumulation and inflammation in the liver organoids can be caused to occur well through free fatty acid treatment, and the phenotypes of non-alcoholic fatty liver can be better expressed.

Abstract: Embodiments include a method for manufacturing a hot-rolled coil and a method for correcting the shape of a hot-rolled coil. In one embodiment, the method for manufacturing the hot-rolled coil includes the steps of: reheating a steel slab comprising 0.18 to 0.56 wt % carbon (C), 0.1 to 0.5 wt % silicon (Si), 0.7 to 6.5 wt % manganese (Mn), more than 0 wt % but not more than 0.02 wt % phosphorus (P), more than 0 wt % but not more than 0.02 wt % sulfur (S), more than 0 wt % but not more than 0.3 wt % chromium (Cr), more than 0 wt % but not more than 0.004 wt % boron (B), 0.01 to 0.04 wt % titanium (Ti), and the remainder being iron (Fe) and other inevitable impurities; hot-rolling the steel slab at a finishing mill delivery temperature of 850° C. to 950° C., thereby forming a hot-rolled sheet; and cooling the hot-rolled sheet, followed by coiling at a coiling temperature of 700° C. or higher.

Abstract: An apparatus for measuring a temperature of a material includes a body unit disposed on an exit side of a heating furnace; a temperature measuring unit installed on the body unit and constructed to measure a temperature of a material which is extracted from the heating furnace; a foreign substance removing unit installed on the body unit and constructed to inject a fluid toward the material so as to remove foreign substances adhered to the material; and a moving unit installed on the body unit and constructed to move the temperature measuring unit.
