Abstract: Provided are a magnetic cell for controlling a shape of a pipe with fluid flow including a magnetic material in the cell, a method of producing the same, and a system for controlling a shape of a pipe with fluid flow and an artificial intelligence planning system for controlling a shape of a pipe with fluid flow using the same, and a repulsive force or attractive force between the magnetic cells is used to induce expansion or contraction of the pipe with fluid flow to control the shape of the pipe with fluid flow.

Abstract: Provided is an obstructive sleep apnea syndrome diagnosis method using machine learning. An embodiment of the present invention is directed to providing an obstructive sleep apnea syndrome diagnosis method using machine learning, which diagnoses obstructive sleep apnea syndrome by extracting parameters related to obstructive sleep apnea syndrome from a geometrical shape of an airway and performing machine learning using data calculated through simulation. Another embodiment of the present invention is directed to providing an obstructive sleep apnea syndrome diagnosis method using machine learning, which improves accuracy of diagnosis of obstructive sleep apnea syndrome and proposes a quantitative standard by diagnosing the obstructive sleep apnea syndrome from the geometrical shape of the airway as described above.
