초고층 구조물에 대한 구조 설계 시, 구조물의 바람에 대한 동적응답특성을 파악하는 것은 매우 중요하다. 본 연구는 자기상관함수와 상호상관함수의 퓨리에 변환을 통해 얻어진 스펙트럼밀도와 크로스 스펙트럼밀도를 이용하여 주파수영역에서의 상관성을 분석하여 이를 파악하고자 한다. 이를 위해 풍동실험을 통해 형상비(H⁄√BD)가 4와 6인 정형적인 건축물에 대하여 우리나라 지표면조도구분 A, B, C, D와 기본풍속 25, 35, 45m/s에 따라 수평방향과 수직방향에 대하여 코히어런스와 디케이 팩터를 분석하였다.

Purpose: The purpose of the study is to examine the influence of physical fitness on a nonverbal intelligence score and cortical networking. Methods: Participants were twenty four high-fit and twenty one low-fit middle school students. K-CTONI-2 was used to measure nonverbal intelligence less influenced by educational experience and verbal ability. Cortical activation at F3, F4, C3, C4, P3, P4, T3, T4, O1, and O2 has been recorded during intelligence test. Inter-hemispheric and intra-hemispheric coherences were calculated to examine cortico-cortical communication. Results: As the behavioral results, nonverbal intelligence score and accuracy were not significant different according to physical fitness. The result of coherence revealed that coherence at right hemisphere which is related to visual-spatial processing was higher in high-fit but coherence at left hemisphere related to verbal-analytic processing was higher in low-fit group. Conclusion: The results imply the greater neural efficiency during intelligence test in high-fit relative to low-fit group.
