  • We carried out geometrical, kinematic, and geomechanical analyses on a lineament (the Imgok fault) near Gangneung, observed in ASTER images and aerial photographs, and field surveys. Earthquake focal mechanism solutions, used to estimate the present-day stress state, revealed that the direction of maximum compression is approximately N$70^{\circ}$E and that the stress condition is in favor of either strike-slip or reverse movement on the fault. The strike of the fault is not ideal for slip under the present-day stress field and thus the fault has a low slip tendency. However, the fault may be able to slip if the frictional coefficient (${\mu}$), representing the resistance of the fault to slip, is sufficiently low (e.g., ${\mu}$ < 0.25).

  • The systematic study of recent freshwater ostracods were conducted on the materials collected from 48 localities in South Korea. Four species of ostracods are identified, and all of them are new to South Korea : Cyprinotus uenoi Brehm , 1936, Heterocypris incongruens (Ramdohr, 1808), Dolerocypris fasciata(O.F.Mller, 1776 ), Dolerocypris sinensis Sars, 1903. Up to now seven species (5 species and 2 subspecies ) of recent ostracods are known to South Korea.

  • The residual lipid analysis has been used for finding out the information related to the life style of ancient people. In order to achieve this goal, it must be precedented by building a database of residual lipid analysis of the present creatures. In this study, we performed residual lipid analysis of a cow and a dog, which were the present samples. We hope the results of this study will be a primary reference for the future analysis of archaeological materials.
