    Abstract: Provided is a digital feedback linearizing apparatus 100 and method to linearize a power amplifier (PA), which is intended to improve the linearity of a mobile communication base station PA 10, and more particularly, a digital feedback linearizing apparatus 100 and method to linearize a PA 10 using a digital signal process (DSP) 110 and a feedback technology, in which a predistorted signal u(t) required for linearization is generated by adding an input signal x(t) input through a predetermined path to an inverse distortion component e(t) corresponding to a distortion component of the PA 10 and in which a linearly amplified output signal y(t) is obtained by passing the predistorted signal u(t) through the PA.

    Abstract: The present invention relates to a plastic photonic crystal fiber for terahertz wave transmission and a method for the manufacturing thereof. More particularly, the present invention is directed to a plastic photonic crystal fiber that can be easily manufactured and has low loss characteristics to be used as a waveguide of terahertz waves. The plastic photonic crystal fiber includes a crystal defect component having a longitudinal axis and a photonic crystal component surrounding the crystal defect component. The photonic crystal component has an array of a plurality of plastic elements having longitudinal axes and forming a 2-dimensional photonic crystal structure with a predetermined lattice constant. Further, the plastic photonic crystal fiber of the present invention can be used as a preform from which a plastic photonic crystal fiber for an optical communication (400-800 nm) can be drawn.

    Abstract: The present invention relates to calix[4]arene-nucleoside hybrids containing calix[4]arene moieties and calix[4]arene-oligonucleotide hybrids as a DNA hairpin structure mimics synthesized by using the calix[4]arene-nucleoside as a key building block. Calix[4]arene-nucleoside and calix[4]arene-oligonucleotide hybrids of the present invention can effectively recognize DNA or RNA through triplex formation by bonding between calix[4]arene containing cavity and biologically active substance.

    Abstract: Disclosed are novel peptides inhibitory of the activity of vascular endothelial growth factor (VEGF) and their use in the treatment of angiogenesis-related diseases, including cancer. A combinatorial library of peptides consisting of six amino acid residues were chemically synthesize and, from the library, specific amino acid residues for each amino acid position were screened by comparing their inhibitory activity against VEGF binding to the cell surface receptor. The novel peptide sequences thus obtained bind to VEGF and block the binding of VEGF to its receptors present on the surface of vascular endothelial cells, thereby inhibiting the hormonal activity of VEGF. The peptides inhibit the angiogenesis induced by VEGF and human cancer cells. Also, the peptides inhibit growth and metastasis of human cancer cells transplanted to mice. Thus, the peptides can be used to treat angiogenesis-related diseases, including cancer, diabetic retinopathy, rheumatoid arthritis, etc.
