  • Tunnel behavior measured by monitoring during construction is a main item for safety evaluation and it depends widely upon local geological characteristics. To assess in this study how much the geological factors influence on tunnel behavior for each RMR factor, a quantification analysis was carried out using tunnel face maps and measurements as explanatory variables and dependent variables, respectively. The results showed that average significance of the influence of RMR factors - R1, R2, R3, R4 and R5, on tunnel displacements are 17.0%, 20.4%, 20.4%, 11.6% and 30.6%, respectively, and this probably indicates that the groundwater condition played a significant role for the tunnel displacement.

  • Drilled sediment core was acquired from Jinheung catchment which was located at Jeollabuk-do Jeongeup city. Elements concentration variation were studied by neutron activation analysis using sediment core by divided 1 cm depth interval. The concentration of major element such as Na, K were increased but Fe was decrease with depth. Minimum elements concentration and particle size were observed at 17 cm depth. This depth was considered 1969 year which was great dry year recorded from the rain fall data and the sedimentation rate was calculated $0.197g{\cdot}cm^{-2}{\cdot}year^{-1}$.

  • The purpose of this study is to measure the trust and distrust perception of our society about science and technology. In addition to examining trust and distrust in science and technology, we also looked at trust and distrust in geoscience technology. In addition, by comparing the levels of trust and distrust in science and technology and geological resource technology, the implications for improving the reliability of geological resource technology are drawn. This study surveyed male and female office workers over 20 years of age working in the Seoul metropolitan area on the trust and distrust of science and technology. The results of this study show that respondents showed above-average trust in science and technology and geological resource technology. According to the gender or age of respondents, there was no difference in trust and distrust of science and technology and geological resource technology. As a result of examining the difference between trust and distrust in science and technology and geological resource technology, respondents showed higher trust scores in science and technology than geological resource technology. These results suggest that current communications activities on geological resources should be more active and diversified.
