설악산에 자생하는 관속식물상을 1984년부터 2010년까지 조사한 결과, 총 109과 463속 814종 1아종 122변종 57품종 총 994분류군이 분포하는 것으로 확인되었다. 조사된 994분류군 중 한국특산식물은 53분류군, 희귀 및 멸종위기식물은 60분류군, 식물구계학적 특정종은 V등급 42분류군, IV등급 27분류군, III등급 58분류군, II등급 57분류군, I 등급 64분류 군 등 총 248분류군이 분포하였다. 그리고 귀화식물은 60분류군이 확인되었는데 국화과가 전체의 31.7%로 가장 높게 분포하였으며, 귀화율은 6.0%로 나타났다. 또한 생활형조성은 반지중식물(27.6%), 지중식물(25.0%), 지상식물(21.8%) 등이 높게 나타났다.

This study was conducted to investigate the specific expression genes in the cloned bovine tissues. Donor cells, cloned tissues were analysed by RAPD-RFLP method. The results were detected three genes (CH-U7B, CH-U7M and CH-U7P) in the cloned fetus. It was found a single copy genes by southern hybridization. Sequence analysis of CH-U7M gene was shown 99% homology to a previously reported EST from a cloned bovine fetus. The putative ORF was encode a protein of hydrophobicity index 0.03. Semi-quantitative RT-PCR by using the CH-LS001 specific primer was remarkably detected in the lung tissue of cloned fetus. Further investigation of these genes may provide one of the key information to explain the early death, abnormal fetus, large off-spring and the low pregnancy rate in the production of cloned bovine.

Among the efforts to increase the efficiency of organic light-emitting device (OLED), there is a way: doping phosphorescent materials. As a phosphorescent material, complexes of heavy transition metal, platinum, were synthesized. Cl- ion and phenyl group were used as ancillary ligands with 2-(2-pyridyl)benzimidazole (pbi) as a chromophore. The complexes were analysed by FAB-mass spectrometer and absorption and emission spectra were obtained. A phenyl group was able to shift the emission band of the complex even if it's not a chromorphore.
