Abstract: Proposed is a refillable cosmetic container to which an inner container containing cosmetic contents is coupled. The inner container is inserted into an outer container so that a coupling part (22) provided on the upper portion of the inner container (20) is coupled to the stepped part (12) provided on the upper portion of the outer container (10), and a press groove (15) is formed on the first side of the stepped part of the outer container to be recessed downward, so the inner container can be simply separated by the gap formed as the upper portion of the second side of the inner container is lifted upward from the outer container by downwardly pushing the press groove of the outer container on the first side of the upper portion of the inner container, thus making it convenient to refill and use the inner container.

Abstract: An embodiment of the present disclosure provides an arc risk management method comprising: pre-processing measurement values of currents flowing into an electric apparatus; estimating a level of arc energy in the electric apparatus by inputting the measurement values into one artificial intelligence network comprising a first layer including a dilated convolutional neural network and a second layer including a recurrent neural network; and indicating an arc risk to the electric apparatus in a quantitative way according to the level of arc energy.

Abstract: A mobile terminal including a touch screen and a method of controlling an operation thereof are provided. The method of controlling an operation of a mobile terminal includes: displaying a thumbnail image corresponding to an image file on a touch screen to be randomly overlapped; selecting any one of thumbnail images by touch input; and displaying the selected thumbnail image together with an option icon for selecting a quick menu to be distinguished from other thumbnail images. Therefore, a list of stored image files can display thumbnail images in a new arrangement manner and it possible to quickly enter a related menu from the thumbnail image.

Abstract: A method of controlling a mobile terminal and which includes displaying a first screen image on a touch screen of the mobile terminal as an idle background screen, receiving a touch and drag input operation being performed on the touch screen including the displayed first screen image, and displaying a second screen image corresponding to a direction of the touch and drag input operation, said second screen image corresponding to a new idle background screen.
