  • Heavy metals, Cd, Pb, Cu, Mn, Zn in water, sediments and molluscs along coast line of Hwang-hae(Yellow sea)were examined. The collection sited werer close to esturies of Kum-gang and Mankyeong-Gang, where industries have been rapidly developed along the rivers in recent in recent years. Cadmium and lead in water were 0.32ppb and 4.12 ppb respectively on Kun-san, but not on Jang hang. In general, Cd, Pb, Mn and Zn were detected in the regions of mouth paart of rivers, whereas none or far less amounts were detected from Puan, a control site: 20km apart from estury of Mangyeong Gang. Cd and Pb in sediments of Kunsan were 0.46ppm and 9.31ppm respectively and 0.36ppm and 0.41ppm in Shim-po, but far less amounts in Byeon san.Heavy metals in shellfish were: Cd 0.78ppm and Pb 0.42ppm in Kun san, 0.74ppm and 0.74ppm in Shim po, and showed higher values compare to other sites. In general, heavy metal contamination of sedimets and molluscs in each are were correlated with grade of the water pollution due to heavy metals.

  • Lineament is defined generally as a linear feature or pattern on interpretation of a satellite image and indicates the geological structures such as faults and fractures. For this reason, a lineament extraction and analysis using remote sensing images have been widely used for mapping large areas. The Gyeong-gang Fault is a NNE trending structure located in Gangwon-do and Kyeonggi-do district. However, a few geological researches on that fault have been carried out and its trace or continuity is ambiguous. In this study, we investigate the geologic features at Gyeong-gang Fault Zone using LANDSAT ETM+ satellite image and SRTM digital elevation model. In order to extract the characteristics of geologic features effectively, we transform the LANDSAT ETM+ image using Principal Component Analysis (PCA) and create a shade relief from SRTM data with various illumination angles. The results show that it is possible to identify the dimensions and orientations of the geologic features at Gyeong-gang Fault Zone using remote sensing data. An aerial photograph interpretation and a field work will be future tasks for more accurate analysis in this area.

  • "HanBangEuiHakGangSupSeo" is a total medical book written by Sung Joo Bong and published in 1935, to be used in a Korean medical school in Daejon. It was published to raise generation and reconstruct Korean medicine and get the authors medical expriences across to lots of people and get it more useful. "HanBangEuiHakGangSupSeo" strengthen the study of classics of Korean medicine and it shows various efforts to reconstruct Korean medicine done those days.
