자기지전류 탐사의 적용에 있어 인공잡음의 영향은 탐사의 승패를 좌우하는 매우 중요한 요소이며 인공잡음의 영향을 최소화할 수 있는 탐사의 설계와 자료처리가 요구되고 있다. 본 연구에서는 수치공간자료들에서 추정되는 인공잡음의 영향과 실제 탐사 자료 간의 상관관계를 살펴봄으로써 자기지전류 탐사에 있어 공간자료의 활용가능성을 고찰하였다. 60Hz 조화파 대역에서는 건물과 도로가 주요한 인공잡음원이며 잡음원의 분포와 자기장의 파워가 서로 상관관계를 가짐을 확인하였다. 'Dead band'로 불리는 0.05-0.5Hz 대역에서는 매우 강한 분극을 가지는 신호가 광범위하게 관찰되고 있으며 이는 탐사지역에 인접한 거대도시의 영향으로 추정된다.

The purpose of this study was to examine the relationship between science teaching practices and beliefs about the nature of science. Defining teachers' beliefs as a broad construct, the researcher tried to examine not only the teachers' understanding about the nature of science, but also the effect and reflection in science teaching practices with regards to the nature of science. Guiding research questions were how the teachers' science teaching practices reflected their beliefs about the nature of science. The methodology of this study was qualitative approach that included interviews, classroom observations, and instructional materials. At an urban area of Korea, five beginning elementary teacher was chosen. The cross-case and grounded theory study design were adopted as data analysis process. The results of data analysis were checked by teachers for internal validity. This study identified the teachers' beliefs about the nature of science suggested by many researchers and revealed that these teachers' beliefs reflected a little in science teaching practices. On the occasion it was reflected, restricted merely within the narrow limits the way to teach the concepts and contents presented in science curriculum. In addition, some of the obstacles that these teachers' beliefs did not reflect the science teaching practices with regards to the nature of science were investigated in this study.
