Brain-Waves Analysis according to Ego-state and OK-gram of Transactional Analysis Theory

본 연구는 성격구조인 자아상태(Ego-state)의 변화를 통해 자신의 성장과 건강의 유익성을 평가하고 있 는 교류분석(Transactional Analysis : TA) 과 사람의 생체신호 중 뇌에서 발생하는 전기적 신호를 모니터 링하는 뇌파를 이용하여 객관적으로 측정할 수 있는지를 알아보았다. 뇌파 검사결과, M형은 건강한 성인의 뇌파 소견으로 잠을 자지 않은 상태에서 후두부에서 a, β가 우세하 게 관찰되었다. 특히, β는 긴장하거나 집중되는 정신 활동시 뇌 전체에 광범위하게 나타는데, M형의 실험자 들은 N형의 실험자들과는 달리 안정된 상태에서도 β가 주종을 이루는 것을 알 수 있었다. N형은 건강한 성인의 뇌파 소견으로 잠을 자지 않은 상태에서 후두부에서 a, β가 우세하게 관찰되었다. 특히, 안정시에는 긴장이나 집중하는 M형과 달리, 긴장과 눈깜박임 같은 잡음도 나타나지 않았다. 더불어 이고그램의 패턴과 상관없이 A자아의 수치가 높은 대상자는 안정된 상태로 빨리 돌아오지 않고 눈깜박임과 침삼킴, 잡음이 많은 것을 보였다. 그리고 자아상태와 인생태도의 데이터의 차이가 모든 항목에서 같거나 -5이하인 11명의 뇌파가 전반적으로 20μV의 낮은 진폭을 보였다. 결론적으로 본 연구는 교류분석이론의 성격 패턴의 이론과 뇌파의 소견이 일치하는 것을 규명하였으며, 이고그램의 각 자아상태에 따라 뇌파 역시 관련이 있음을 확인하였다.

Abstract For five diagnostic X-ray generators (DR), four units turned out to be appropriate in tests on the reproducibility of radiation output suggested in the IEC 60601-2-54 standard, but in one unit of the X-ray equipment, an item measured in a combination of 50% of the highest tube voltage of the diagnostic X-ray equipment, the test setting of Group C with authorized output doses between 1 μGy and 5 μGy of mAs turned out to be inappropriate. As a result, the radiation dose to the IEC 60601-2-54 standard for quantification standards proposed by the radiation output from diagnostic X-ray imaging device reproducibility of performance management should be aware that an important evaluation factor.
