Abstract:
Results: Dirty electricity was reduced by more than 90% in the three schools and during this period teacher health improved as did student behavior in the middle/elementary schools. Headaches, general weakness, dry eyes/mouth, facial flushing, asthma, skin irritations, overall mood including depression and anxiety improved significantly among staff. Of the 44 teachers who participated 64% were better, 30% were worse, and 6% did not change. Behavior of high school students did not improve but elementary/middle school students were more active in class; more responsive, more focused; had fewer health complaints; and had a better overall learning experience.
Conclusions: Dirty electricity in schools may be adversely affecting wellbeing of teachers and behavior of their students, especially younger students in middle and elementary school. Power line filters improve power quality and may also protect those who are sensitive to this energy. Work on electric and magnetic field metrics with and without Stetzer filters urgently needs to be carried out to determine just what characteristics of the dirty electricity may be interacting with the people.
-결과:불량전기는 3개의 학교에서 90%이상 줄어들었으며 이 기간 동안 교사의 건강은 초중교 학생들이 했던 행동 처럼 향상되었다. 두통, 일반적인 신경쇠약, 건조한 눈/입, 얼굴홍조, 천식, 피부 자극, 우울증과 불안을 포함한 전반적인 분위기는 직원들 사이에서 크게 향상되었다. 참가했던 44명의 교사중 64%는 더 좋아졌으며 30% 나빠졌고 6%는 변함이 없다. 고등학교 학생들의 행동은 개선되지 않았지만 초중교 학생들은 수업에 적극적이었다. 또한 건강이상이 줄었으며 전반적으로 좋은 학습경험이 되었다.
결론: 학교에서 불량전기는 반대로 교사들의 행복과 그들 학생들(초중학생)의 행동에 영향을 미친다. 필터는 전력품질을 향상시키고 이 에너지에 민감한 사람들을 보호할 수 있다. 스테이쳐 필터 없이 전기 및 전자기장에 대한 작업은 불량 전기가 사람들과 상호작용할 수 있다는 특성을 결정하기위해 수행할 필요가 있다.
