  • The purpose of this study was to examine the relationship between children's information processing ability and basic learning abilities. To collect the data, two tests were given to 99 children. The Korean K-ABC(Moon & Byun, 1997) and Pictorial Basic Learning Abilities for Children(Kim, 2011) were used to examine the relationship between children's information processing and basic learning abilities. The collected data were analyzed by correlation analysis and multiple regression analysis. According to the results of this study, there was a significant positive correlation between information processing(sequential processing, simultaneous processing) and basic learning abilities including reading, writing, and basic mathematics. And information processing significantly affected basic learning abilities. Namely, simultaneous processing explained 22% of basic learning abilities and by adding sequential processing, the explanation was increased to 25%. In conclusion, the results of this study suggest various implications about children's basic learning abilities. These implications will help teachers and parents to understand their children's learning.

  • Rocking behavior of shallow foundation during the earthquake can reduce the seismic load of the superstructure. The dynamic centrifuge tests were performed to investigate the availability of using rocking behavior for the weathered soil condition. The centrifuge test model was composed of the weathered soil, shallow foundation and single degree of freedom structure. And the accelerations of soil, foundation and structure, and the foundation settlement were measured during the earthquake. From the test result, the seismic load of the structure for the strong earthquake input was reduced by the rocking behavior with foundation uplift and the maximum foundation settlement was less than 0.5% of the foundation width. This shows the potential that the rocking foundation concept can be used in the economical seismic design of foundation for the weathered soil in the future with additional research and verification.

  • 지진 등과 같은 외부 진동하중에 의해 발생되는 구조물의 진동은 구조물의 독립적 거동뿐만 아니라 지반과 구조물 기초의 접촉면을 통해 상호 영향을 미치게 된다. 특히 LNG 저장탱크나 원자력발전소 등과 같이 대현 상부구조물의 경우 상호작용력은 크게 작용하게 된다. 본 연구에서는 상부 구조계의 단순화된 형태인 기초계의 동적거동을 파악하기 위해 주파수영역 경계요소법을 사용하여 수치적으로 연구하였다. 반무한체 상에 존재하는 무질량 강체 표면기초에 대해 반무한 기본해를 이용하여 동적거동이 고찰되었으며 기존의 해석결과와 비교, 검토하여 본 연구방법의 타당함을 입증하였다.
