  • The Gyeong-Ju earthquake in the magnitude of 5.8 on the Richter scaleoccurred in September 12, 2016. Because there are many nuclear power plants (NPP) near the epicenter of the Gyeong-Ju earthquake, the seismic stability of nuclear power plants is becoming a social problem. In order to evaluate the safety of seismically isolated NPP, the seismic response of a NPP subjected to the Gyeong-Ju earthquake was compared with those of 30 sets of artificial earthquakes corresponding to the nuclear standard design spectrum (NSDS). A 2-node model and a simple beam-stick model were used for the seismic analysis of seismically isolated NPP structures. Using 2-node model, the effect of internal temperature rise, decrease of shear stiffness, increase of lateral displacement and decrease of vertical stiffness according to nonlinear behavior of lead-rubber bearing (LRB) were evaluated. The displacement response, the acceleration response, and the shear force response of the seismically isolated nuclear containment structure were evaluated using the simple beam-stick model. It can be observed that the seismic responses of the isolated nuclear structure subjected to Gyeong-Ju earthquake is significantly less than those to the artificial earthquakes corresponding to NSDS.

  • This study was investigated preschool the prinicipal and mother's agreed to the question sheet by writing mother's along with hand From April 3 distribute to May 30th 2006 collected. The Target was a part preschool childern between analysis Taegu city 242 persons and Gyeong-ju city 201 persons. The results were follows; 1. The most popular by the reason hungry eating of bewteen-meal intake. 2. The most popular by the choice motive of between-meal intake to mother's of admonition (Taegu city of 61.2%, Gyeong-Ju city of 63.7%.) 3. The most popular by the time of bewteenmeal intake to afternoon between evening (Taegu city of 90.5%, Gyeong-Ju city of 88.1%.) 4. The most popular by the place of between-meal intake to Taegu city and Gyeong-Ju city it's home.
