Abstract: A method of controlling injection of a drug includes receiving a captured medical image of an object, identifying an object of interest from the medical image, based on a position and a shape of the object of interest, determining a drug injection position, based on the position and the shape of the object of interest, determining a plurality of electrode insertion positions, the plurality of electrodes being configured to supply a current to move the drug, defining a drug movement path based on a shape of the identified object of interest, generating current sequence information to move the drug along the drug movement path, the current sequence information defining a current applied over time to each of the plurality of electrodes, and outputting the current sequence information to a current source apparatus.

Abstract: A diffuser which reduces noise generated due to a flow of cool air when the cool air is discharged from a supply duct configured to supply cool air generated from a body provided at outdoors to the indoors, and an air conditioner having the same are provided. The diffuser includes a coupling part coupled to the supply duct, an extension part extending from the coupling part while having a taper shape such that cool air supplied through the supply duct is guided to the indoors, a mesh provided to surround an outer side of the extension part, and a housing accommodating the coupling part and the extension part, and having an opening configured to discharge the cool air supplied to the extension part to the indoors.

Abstract: A diffuser capable of reducing noise generated due to a flow of cool air when the cool air is discharged from a supply duct configured to supply cool air generated from a body provided at outdoors to the indoors at a high speed as the diffuser is coupled to the supply duct, and an air conditioner having the same are provided.
