  • This study investigated how children rely on the mind of the speaker to infer unfamiliar words. Sixty 3 to 5-year-old children were interviewed individually with word inference and false belief tasks. Children's sensitivity to the speakers' intentions and prior experiences increased with age. Unexpectedly, their performance was not different with the condition of mind construct. Children's inferring word meanings were positively, but not significantly, correlated with understanding others' false beliefs.

  • A TVS and Varistor are preservative equipment against electro static discharge(ESD). We use a TVS for I/O protection of a circuit which has faster response time than a Varistor. And a Varistor has large power capability, therefore, which be used in input stage for internal pressure prevention. This paper will compare a TVS with a Varistor with respect to response characteristic to ESD in DC 24[V] low voltage circuit.

  • 국내 접지시스템 설계시 가장 널리 사용되는 것은 ANSI/IEEE Std. 80-2000이나 국내 접지설계 환경의 적정성 여부는 검토되고 있지 않다. 따라서, 본 논문에서는 국내 접지설계 환경을 고려한 새로운 접지도체의 굵기 산정방법과 접지도체의 위험전압 산정방법, 접지도체의 Grid간격 산정방법을 적용하여 ANSI/IEEE Std.80-2000을 보완한 새로운 접지시스템 설계 방법을 제시하였다.

  • This study is contents about Separation ASCON, the Tiles and the Reds Bricks using the heavy suspension. The specific gravity of ASCON, the Tiles and the Reds Bricks are under 2.3. So we make the heavy suspension which the specific gravity is 2.3 and we separated ASCON, the Tiles and the Reds Bricks.
