The present invention is directed to novel retinoid-related orphan receptor gamma modulators, processes for their preparation, pharmaceutical compositions containing these modulators, and their use in the treatment of inflammatory, metabolic and autoimmune diseases mediated by ROR\u03b3. The operation analysis section regenerates the operation state on which the specified solution is reflected, and the display section displays the cause of the defect, the solution and the regenerated operation state to the user. The magnetic field forms the magnetic lens and focuses the electrons emitted from the emitter.
