Abstract: Disclosed is a video processing system including multiple unmanned aerial vehicles (UAVs) configured to capture a video of a fire site, wherein each UAV has a control unit including an input layer and a first hidden layer (hidden layer 1) and a central server connected to the multiple UAVs by wireless communication, wherein the central server includes multiple hidden layers and an output layer. The video processing system performs a learning process to determine whether a fire has occurred using a feature map in which an original video is difficult to recognize and personal information is protected. Thus, it is possible to fundamentally prevent the exposure and infringement of personal information.

Abstract: The present disclosure relates to a method for providing information for determining lung tumor through inhalation of a fluorescent contrast agent, more particularly to a method of inhaling a small amount of Indocyanine green. The present disclosure does not have the problem of the existing intravenous injection that the administered fluorescent contrast agent is distributed throughout the body. In addition, when comparing the cancer detection efficiency of inhalation administration and intravenous injection, the inhaled fluorescent contrast agent exhibits remarkably higher cancer detection effect than the intravenously injected fluorescent contrast agent.

Abstract: The present invention relates to an adenine base editor from which cytosine editing activity is removed, a method of editing an adenine base, and method of editing an adenine base. In the present invention, it was confirmed that four mutations (V106W, D108Q, F148A and F149A) in adenosine deaminase increase the specificity for adenine editing by reducing cytosine base editing efficiency, and ABE variants were manufactured by introducing respective mutations into a variety of more improved adenine base editors than ABEmax, and tested, confirming that the mutations significantly decrease a cytosine editing effect. Therefore, the adenine base editor according to the present invention is able to more accurately edit adenine, and the method of editing an adenine base can be effectively used in the field of gene therapy that has to accurately edit only adenine in all living organisms including humans, plants and bacteria or novel crop development.
