Abstract: The present invention provides an apparatus for recycling of waste batteries, the apparatus including a work part in which objects are placed to heat the objects and recover valuable metals from the objects, wherein in the work part, the objects are heat-treated in a mixed reducing gas atmosphere in which log(PCO2/PCO), which is a logarithmic value of a division value of partial pressures of carbon dioxide and carbon monoxide, ranges from ?2.15 to 2.5. According to the present invention, heat treatment efficiency can be maximized by preventing carbon emission in a process of heat treatment of waste batteries and actively controlling a gas environment in which carbon monoxide and carbon dioxide are mixed.

Abstract: The present invention provides an apparatus for vertical recycling of waste batteries, the apparatus including a heating part heating objects located inside a work part and a controller controlling an operation of the heating part, wherein the controller controls at least one or more of a temperature increase rate and a temperature increase time of the heating part. According to the present invention, through heat treatment based on an optimal temperature increase rate, it is possible to maximize heat treatment efficiency, since a storage part to which objects are input can be easily moved and firmly fixed and worker intervention in a high-temperature, high-pressure environment can be minimized, convenience and safety can be significantly improved, and through the present invention that adopts a vertical dry smelting method, mass treatment of objects is possible without performing pretreatment processes thereon, and the generation of harmful substances can be minimized.

Abstract: Disclosed are a content box providing method and a user terminal.

Abstract: A link shared through a chat room in a chat application is displayed. When a selection of the link is received, a content execution result corresponding to the link through an in-app browser of the chat application or an external browser distinct from the chat application is displayed. A notification for a new chat message is then displayed while the content execution result is being displayed through the in-app browser or the external browser. When a selection for the notification of the new chat message is received, the display of the content execution result is switched to a display of the chat room in which the new chat message was received. A content box, which enables access to the content execution result, is displayed on the switched display of the chat room.

Abstract: Disclosed are a content box providing method and a user terminal. The method may comprise the steps of: displaying a link shared through a chat room in a chat application; when a selection for the link is received, displaying a screen of a content execution result corresponding to the link through an in-app browser of the chat application or an external browser distinct from the chat application; displaying a notification for a new chat message while the screen of the content execution result is being displayed through the in-app browser or the external browser; when a selection for the notification of the new chat message is received, switching the screen of the content execution result to a screen of the chat room to which the new chat message received; and displaying a content box, which enables access to the content execution result, on the switched screen of the chat room.

Abstract: A hearing assistance device for informing about the state of a wearer includes: an input part configured to receive a selection input for either an ambient listening function or a music listening function; at least one microphone configured to pick up ambient sound; a speaker configured to send the ambient sound to the wearer; a communication part configured to perform wired or wireless communication with an external electronic communication device; an indication part configured to indicate that the ambient listening function or the music listening function is being performed; and a controller configured to perform the ambient listening function to pick up ambient sound from the microphone according to a selection input from the input part and send the ambient sound to the speaker, or perform the music listening function to play stored music or music received from the communication part and send the music to the speaker.

Abstract: Provided is a computer-implemented display control method including a first display operation of displaying, in a second region of a screen, a first page on which contents belonging to a first category are arranged, and listing a plurality of categories in a vertical or horizontal direction and displaying the plurality of categories in a first region of the screen, wherein the first page is displayed to be scrollable in a direction in which the plurality of categories are listed, a recognition operation of recognizing a scroll signal which is input with respect to the first page, a determination operation of scrolling the first page based on the scroll signal, and generating a category change command based on the scroll signal if scrolling is not possible according to a position of the first page, and a second display operation of displaying, on the second region, a second page on which contents belonging to a second category are arranged, if it is determined to change the category based on the scroll signal.
