Abstract: A method of a first user equipment (UE) may comprise: receiving a downlink (DL) reference signal transmitted by a base station using a beam included in a beam candidate group to be used for sidelink (SL) communication with a second UE; measuring a DL reference signal received power (RSRP) of the DL reference signal; determining a transmit power of a beam included in the beam candidate group based on the measured DL RSRP; and transmitting SL data to the second UE with the determined transmit power.

Abstract: The present invention relates to a voice signal processing method according to a state of an electronic device, and an electronic device therefor. An electronic device according to various embodiments comprises: a microphone; and a processor, wherein the processor can be configured to: obtain a voice signal using the microphone, check a state of the electronic device, and generate a first voice signal by filtering the voice signal using a first method, at least based on a determination of the electronic device being in a first state; generate a second voice signal by filtering the voice signal using a second method, at least based on a determination of the electronic device being in a second state; and transmit to an external electronic device a corresponding voice signal of the first voice signal or the second voice signal. In addition, other embodiments are possible.

Abstract: A mobile terminal is provided that does not have a separate dedicated microphone hole. The mobile terminal preferably includes an ear jack assembly and a microphone unit. The ear jack assembly includes an ear jack plug insert hole. The microphone unit is disposed in a neighborhood of the ear jack assembly. The microphone unit is realized to use a microphone hole for receiving an external note also as an ear jack plug insert hole. Since a microphone hole for a speaker phone is excluded, the microphone unit is advantageous in space utilization, and can contribute to designing an elegance appearance of the mobile terminal. In addition, since the microphone unit is manufactured integrally with the ear jack assembly, manufacturing costs reduce and working efficiency may increase.

Abstract: Disclosed are a novel C5 benzothiazolyl sulfone compound having an acetal protecting group, a method of preparing the same, and a method of efficiently preparing an apo-carotene dialdehyde compound having a polyene dialdehyde structure using the same. Also, a method of efficiently preparing lycopene by olefination (Julia-Kocienski) between the apo-carotene dialdehyde compound (C20 crocetin dialdehyde) and C10 benzothiazolyl geranyl sulfone is provided.

Abstract: An earphone and method for forming the same are provided. The earphone includes an earphone housing, a speaker, and an earcap. The earphone housing includes a speaker mounting portion. The speaker is fixed to the earphone housing, and has a cable that passes through the body and is drawn from the body. The earcap is installed to at least partially enclose the speaker and the housing, and has at least one speaker sound emitting hole therein. The earcap is made of a material that solidifies after a predetermined time elapses, and is manufactured by inserting the material into an ear of a user, and then solidifying the material such that it is suited for a shape of the ear of the user.
