Abstract: The present invention relates to a respirator without breathing resistance, which has an air inlet duct that passes through an inside and an outside of the respirator and that has asymmetrical electrodes and particle capturing plates formed on an inner surface of the air inlet duct; ozone removing element that removes ozone generated by micro-plasma; and high voltage dc-dc converter that provides high voltage to the asymmetrical electrodes. It employs asymmetrical electrodes and particle capturing plates to filter air without generating breathing resistance. When the respirator according to the present invention is used, safety of a wearer may be maintained in accordance with an environment and breathing may be smoothly performed even while introduction of pathogenic bacteria, viruses, fungi, spores, fine dust, or the like included in air may be effectively blocked. Accordingly, the respirator may be widely utilized to maintain the safety of the wearer in various environments.

Abstract: A learning situation determining method and apparatus is disclosed. The learning situation determining method includes collecting psychophysiological response information of a learner on a first learning image, collecting stimulated recall response information of the learner based on a stimulated recall of the learner in response to a second learning image including a same learning content as the first learning image, determining cognitive load in the leaner that is recalled in each learning interval of the second learning image based on the psychophysiological response information and the stimulated recall response information. Alternatively, the learning situation determining method includes determining cognitive load in a learner learning a learning image for each learning interval of the learning image using psychophysiological response information of the learner based on prior knowledge possessed by the learner and task complexity of the learning image.

Abstract: The present invention relates to a method for promoting the generation and secretion of extracellular vesicles from cells by using extracorporeal shockwave. More precisely, the inventors confirmed that the generation and secretion of extracellular vesicles from vascular endothelial cells were promoted by extracorporeal shockwave and further confirmed that siRNA can be transferred into cells without any help of a carrier. The inventors continued to find out that angiogenesis could be inhibited by introducing siRNA to an animal tumor model and succeeded to measure the size and amount of extracellular vesicles secreted by extracorporeal shockwave. Therefore, the present invention can be used in various fields since it can safely promote the generation and secretion of extracellular vesicles from cells.
