Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes treating modules having an opening for taking in and taking out a substrate and which are stacked on each other; and an air flow generating member for generating a downward airflow at each treating module, and wherein the air flow generating member includes: a pan unit configured to supply an air; a spray unit configured to be provided above the treating module and which sprays an air supplied from the pan unit; and an exhaust unit configured to exhaust an air sprayed by the spray unit to outside of the treating module.

Abstract: Provided are a media scanning method and device for a storage medium of a user terminal. The media scanning method includes: determining, when a terminal is booting, whether a storage medium of the terminal meets an execution condition for media scanning; and performing media scanning of a storage medium when the determining determines that the execution condition for media scanning for the storage medium is met.

Abstract: A method for managing permission information of an application in a mobile terminal includes detecting a reference event associated the application, determining a type of the reference event, determining permission information of the application, determining whether to execute an operation of the application based on the permission information, and storing operation performance information related to the operation of the application in a database. A terminal includes an application layer to detect an event associated with a change in permission information of a first application and a second application, and a framework layer to determine whether permission information of the first application is changed with respect to the second application, to determine an event type associated with the change in the permission information, to determine permission information of the first application and the second application, and to determine whether to execute a security program.
