Abstract: Disclosed is an endoscope apparatus. The endoscope apparatus of the present invention includes: an endoscope including a flexible insertion section to be inserted into a human body; a flexible channel attached to the insertion section so that a part forms a passage in a longitudinal direction of the insertion section; and an assistant arm movably inserted into the passage and manipulated by a control device, and the assistant arm includes forceps capable of gripping a human body tissue, and a bending section bent by the control device to pull the human body tissue griped by the forceps.

Abstract: Disclosed are a method and a system for solar photovoltaic power station and the system includes: an unmanned aerial vehicle flying over the sky of a plurality of solar photovoltaic panels included in a solar photovoltaic power station and obtaining and providing a monitoring image by photographing the solar photovoltaic panel; and a computing device correcting the monitoring image and obtaining the corrected monitoring image, and executing a solar photovoltaic power station monitoring application of performing a malfunction area inspection process for the solar photovoltaic panel based on the obtained corrected monitoring image.

Abstract: The present invention relates to a device and method for reconstructing low-frequency conductivity images using MRI without current injection. In the device according to the present invention, low-frequency conductivity is deduced using high-frequency conductivity obtained using MR-EPT, the calculated directional tensor of ions from the water diffusion tensor in a subject, and the volume fractions and diffusion coefficients of the intracellular/extracellular spaces, and low-frequency conductivity images are reconstructed based on the deduced low-frequency conductivity. According to the present invention, low-frequency conductivity images in a subject to be measured such as the human body and an object may be reconstructed using an MRI device without applying current to the subject.
