Abstract: The present invention discloses a power control apparatus and method in a wireless communication system. According to the present invention, among FUE units neighboring to an MUE unit of a victim cell, an FUE unit of an aggressor cell may be derived on the basis of information on RSRP of the FUE unit registered in a closed subscriber group, and a threshold interference value of the FUE unit. Also, power of the derived FUE unit of the aggressor cell may be gradually decreased until an interference of the MUE unit of the victim cell becomes greater than a predefined threshold interference value, and an SINR of the FUE unit of the aggressor cell becomes equal to or greater than a target SINR. Accordingly, CCI can be reduced in a heterogeneous network environment, data transmission speed can be improved, and latency time can be reduced by reducing feedback time.

Abstract: The present invention relates to a variable resistor comprises a first electrode, a second electrode, and a resistive switching layer disposed between the first electrode and the second electrode, wherein the resistive switching layer has a Brown-Millerite structure crystallized in an inclined orientation across the first electrode and the second electrode as an initial structure.

Abstract: Provided is a method and composition using ROS to increase the production of bacteriophage. According to the subject matter, a production amount of bacteriophage is increased several times in the presence of the sublethal concentration of ROS for host bacteria. Therefore, the method and composition of the subject matter can be useful for producing bacteriophage, which is used as an alternative to antibiotics that cause a serious resistance problem.

Abstract: Provided herein is a method of automatically evaluating non-native speakers' pronunciation proficiency, wherein an input speech signal is received, the speech recognition module transcribes it into a text; the text is converted into a segmental string with temporal information for each phone; in the key module of feature extraction, nine features of speech rhythm and fluency are computed; and then all feature values are integrated into an overall pronunciation proficiency score. This method can be applied to both types of non-native speech input: read-aloud speech and spontaneous speech.

Abstract: An antimicrobial peptide and an antimicrobial peptide composition comprising the same are provided. The antimicrobial peptide and the antimicrobial peptide composition have remarkably high antibacterial activity against gram-positive (+) and gram-negative (?) bacteria, compared to wild-type LPcin-I having an antimicrobial ability, which consists of a sequence of 23 amino acids. Also, the antimicrobial peptide can be useful in being easily synthesized and saving production costs since the antimicrobial peptide has a smaller number of amino acids, compared to the wild-type LPcin-I.
