  • Electronic device including metal housing antenna
    Patent number: 10283846
    Abstract: An electronic device is provided including a housing including a first plate, a second plate facing the first plate, and a side member between the first and second plate, a radio frequency (RF) circuit, a processor, a ground member, a first electric path connected between a first port of the RF circuit and a first point of a first conductive portion of the side member, a second electric path connected between a second port of the RF circuit and a first point of a second conductive portion of the side member, a third electric path connected between a second point of the first conductive portion and the ground member, a fourth electric path connected between a second point of the second conductive portion and the ground member, and a fifth electric path connected between one point of the second electric path and one point of the third electric path.

  • Method for mass-producing antifreeze protein derived from polar yeast
    Patent number: 9012179
    Abstract: The present invention relates to a method for mass-producing an antifreeze protein derived from a polar yeast, and more particularly, to a method for mass-producing an antifreeze protein derived from Leucosporidium sp., which is the polar yeast, for synthesizing a recombinant polynucleotide by optimizing and altering a gene, which codes the antifreeze protein derived from the polar yeast, for a yeast expression system, and for expressing same using the yeast expression system.
