Abstract: An example user terminal apparatus includes communication circuitry configured to be connected to a home network comprising a plurality of devices; a display configured to display a UI screen for managing the home network; a sensor configured to sense a user manipulation of the UI screen; and processing circuitry configured to change the UI screen displayed on the display according to the user manipulation. The UI screen is one of a plurality of service pages that are changeable according to a user manipulation in a first direction, the plurality of service pages being pages for respectively providing different home network management services. At least one of the plurality of service pages comprises an area that is displayable on the display according to a user manipulation in a second direction.

Abstract: An electronic stethoscope apparatus includes a bioacoustics sensor configured to sense bioacoustics; a noise sensor configured to sense noise in the sensed bioacoustics; and a noise remover configured to remove the sensed noise and output the bioacoustics from which the noise has been removed.

Abstract: A method, performed by a device, of providing security content includes receiving a touch and drag input indicating that a user drags a visual representation of a first application displayed on a touch screen of the device to a fingerprint recognition area while the user touches the visual representation of the first application with a finger; performing authentication on a fingerprint of the finger detected on the touch screen using a fingerprint sensor included in the fingerprint recognition area; and when the performing authentication on the fingerprint is successful, displaying the security content associated with the first application on an execution window of the first application.

Abstract: A method and apparatus for outputting a bell sound are disclosed. The method includes receiving an ambient noise; extracting a target frequency band from the ambient noise; changing volume of a pre-stored bell sound by using the target frequency band; and outputting the changed pre-stored bell sound. In the apparatus for outputting a bell sound, when a bell sound outputting apparatus receives an incoming call signal, a user may hear a bell sound including a signal in a frequency band not existing in a peripheral environment, and thus may easily recognize the bell sound.

Abstract: A multi-color ink for 3D printing, a 3D printer, and a method of controlling the 3D printer are provided. The multi-color ink for 3D printing including a first ink composition that includes a photocurable material, a photoinitiator configured to cure the photocurable material, a first colorant, and an anti-intercolor bleed agent configured to prevent intercolor bleeding occurring when the plurality of ink compositions come into contact with each other, and a second ink composition that includes a photocurable material, a photoinitiator configured to cure the photocurable material, and a second colorant having an acid moiety involved in a reaction with the anti-intercolor bleed agent to cause aggregation. The multi-color ink for 3D printing may enable a clear image by inhibiting intercolor bleeding that occurs when ink compositions with different colors are printed to be adjacent to each other before curing during 3D printing.

Abstract: A voice converting apparatus and a voice converting method are provided. The method of converting a voice using a voice converting apparatus including receiving a voice from a counterpart, analyzing the voice and determining whether the voice abnormal, converting the voice into a normal voice by adjusting a harmonic signal of the voice in response to determining that the voice is abnormal, and transmitting the normal voice.
