Tetradentate Schiff base ligands derived from 2-hydroxy-1-naphthaldehyde and aliphatic diamine have been synthesized. Cu(Ⅱ) complexes of Schiff base ligands have been synthesized from the free ligands and copper acetate. The mole ratio of ligand to copper was identified to be 1:1 by the result of elemental analysis and Cu(Ⅱ) complexes were in a four-coordinated configuration. The electrochemical redox process of Cu(Ⅱ) complexes in a DMF solution has been investigated by cyclic voltammetry, chronoamperometry, differential pulse voltammetry, and controlled potential coulometry. The redox process of Cu(Ⅱ) complexes is one electron transfer process in quasi-reversible and diffusion-controlled reaction. The electrochemical redox potentials and the kinetic parameters of Cu(Ⅱ) complexes are affected by the chelate ring of Schiff base ligands.

The bulk photopolymerization of methyl methacrylate (MMA) with primary arylsilane (e.g., phenylsilane) and various primary alkylsilanes (e.g., benzylsilane, 3-phenoxyphenyl-1-silabutane, 3-naphthyl-1-silabutane, and 3-chlorophenyl-1-silabutane) was performed to produce poly(MMA)s containing the corresponding silyl moiety as an end group. It was found for the phenylsilane that while the polymerization yields increased and then decreased with a turning point at the molar ratio of MMA:silane=10:1 as the relative silane concentration increases, the polymer molecular weights decreased, and the TGA residue yields and the relative intensities of SiH IR stretching bands increased with increment of molar ratio of silane over MMA. The photopolymerization yield of MMA with the arylsilane was found to be higher than those with the alkylsilanes and without the silanes. Thus, the silanes seemed to significantly influence on the photopolymerization as both chain initiation and chain transfer agents.

옛 전남도청과 전남도경찰국이 1980년 5.18 당시 모습으로 복원될 예정이다. 옛 전남도경찰국을 원형복원하여 민주주의의 산 역사 현장으로 전시와 교육, 소통의 공간으로 활용하여야 할 것이다. 옛 전남도경찰국의 원형복원은 5.18 당시 시민군이 옛 전남도 경찰국에서 했던 일과 흔적을 정리해 원형복원해야 할 것이다. 5.18 당시 안병하 도경국장은 근무지 이탈 없이 최선을 다하여 수습을 위해 노력했고, 상부의 강경진압을 거부하고 시민의 안전을 강조하는 소신을 유지해 초기에 광주시내 무기를 소산시켜 탈취방지 뿐만 아니라 경찰무장으로 인한 더 큰 비극을 막았다. 옛 전남도경찰국의 복원공간은 5.18정신을 기리는 시민교육장으로 또 안병하 도경국장의 민주경찰정신과 위민정신을 기리는 공간으로 활용되길 기대한다.

This paper examines the current status of the Korean tea culture industry and explores ways to restore and develop Korean tea culture by referring to the responses of the neighboring countries of China. In order for the Korean tea industry and tea culture to expand, based on a strong tea industry, high-quality tea should be created to satisfy consumers' needs, health, convenience, and reasonable prices, and effective promotion and marketing should be carried out. In addition, it is necessary to reinterpret the traditional tea house and inherit the spirit of tea.
