The present invention relates to a method and system for providing 'diagnosis-aiding information', the method and system being capable of diagnosing cancer and the like of a patient by using medical imaging. According to the present invention, the system for providing the diagnosis-aiding information comprises: the image receiving part for receiving the medical images acquired in the first energy band and the medical images acquired in the second energy band; and the 'analysis- and diagnosis-aiding information providing part for providing diagnosis-aiding information generated by analyzing the medical image acquired in the first energy band and the medical image acquired in the second energy band, wherein the &#x2018;analysis and diagnosis-aid information providing unit' provides the diagnosis-aiding information by measuring the HU values in the region of interest (ROI) of the medical images acquired in the first energy band and the medical images acquired in the second energy band and comparing the HU values of the ROI of two medical images.

Method for providing diagnosis aid information by using medical images, and system therefor

The present disclosure provides a cooling system of an emergency cooling tank, which enables long-term cooling without refilling cooling water, in case of the change in a quantity of heat transferred to the emergency cooling tank according to a lapse of time upon an occurrence of an accident of a nuclear reactor, and a nuclear power plant having the same. The emergency cooling tank cooling system includes an emergency cooling tank, a heat exchanging device installed to be exposed to an outside of the emergency cooling tank to operate in air, and configured to externally emit such that the operation of the emergency cooling tank is continued even without refilling the cooling water, and an opening and closing unit installed at an upper portion of the emergency cooling tank to be located higher than a water level of the cooling water.

The present invention relates to an antimicrobial composition for uracil non-secretory (URA&#x2212;) bacteria, comprising uracil, uracil precursors, uracil analogs, or uracil-secreting opportunistic pathogens as an active ingredient; and a composition for preventing cell damage caused by uracil-secretory (URA+) bacteria, comprising ROS scavengers as an active ingredient. The present invention also relates to food or feed for antimicrobial activity and preventing cell damage, comprising said composition; a method for controlling dual oxidase (DUOX) activation, the generation of reactive oxygen species (ROS), or the level thereof; a method for producing cells, wherein DUOX activation, the generation of ROS, or the level thereof are controlled; and a method for providing information on gut pathogenicity in isolated bacteria. The composition of the present invention has effects for preventing symptoms caused by bacteria according to a mechanism which has been unknown in the art. Further, the present invention can be efficiently utilized for establishing prevention and treatment strategies for symptoms caused by bacteria later, as therapeutic strategies can be readily established by bacterial classification based on criteria that can be easily confirmed.

Composition for controlling a gut immunity and use thereof

The present disclosure may disclose a multi stage safety injection device, including a safety injection tank formed to contain coolant to be injected into a reactor vessel by a gravitational head of water when an accident occurs in which the pressure or water level of the reactor vessel is decreased, a pressure balance line connected to the reactor vessel and safety injection tank to form a pressure balance between the reactor vessel and the safety injection tank, and a set of safety injection lines connected to the safety injection tank and the reactor vessel to inject coolant to the reactor vessel in a pressure balance state between the reactor vessel and the safety injection tank, and connected to the safety injection tank with different heights to reduce a flow rate of coolant injected into the reactor vessel step by step according to the water level reduction of the safety injection tank in order to inject coolant to the reactor vessel at multi stages.
