  • Patent number: 11924773
    Abstract: The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.

  • Publication number: 20210147482
    Abstract: The present invention relates to a peptide for inhibiting bone resorption and, more specifically, to a peptide for inhibiting bone destruction by inhibiting the differentiation and activity of osteoclasts. According to the present invention, a peptide for inhibiting bone resorption can inhibit bone destruction by inhibiting the differentiation and activity of osteoclasts, and thus can be used as a therapeutic agent for various bone diseases caused by an excessive increase in the activity of osteoclasts.

  • Patent number: 10821065
    Abstract: The present invention relates to: a composition for inhibiting biofilms, containing, as an active ingredient, a peptide derived from human ?-defensin-3; and a method for inhibiting biofilms by using the composition. The peptide according to the present invention inhibits bacterial biofilms even when used alone and exhibits a remarkably increased biofilm inhibitory effect when used in combination with a conventional dental therapeutic agent, and has an effect of preventing a tooth discoloration side effect caused by a conventional dental therapeutic agent.
