본 연구는 2009년 3월부터 2010년 2월까지 S시 M동에 위치한 A청각장애특수학교 학생 39명(실험군 25명, 대조군 14명)을 대상으로 뉴로피드백 훈련이 청각장애학생들의 정서적 성향에 미치는 영향을 보고자 하였다. 이를 위하여 뇌파측정을 하였으며 뇌파 정보를 토대로 뉴로피드백 훈련을 적용하여 훈련 전과 후의 뇌 기능 변화 결과를 분석하였다. 뇌파측정 결과 가장 낮은 점수를 훈련 모드로 채택하여 A학교 훈련실에서 일주일에 2회 실시하였으며, 1회당 훈련 시 간은 40분간, 방학을 제외한 9개월 정도를 실시하였다. 정서적, 심리적 반응 측정을 위한 도구는 POMS(Profile of M ood State) 기분상태 설문지를 사용하였다. 연구결과 첫째, 주의지수(좌 우), 항스트레스 지수(좌 우)가 통계적으로 유의 하였다. 둘째, 청각장애 학생들의 기분상태 설문지가 통계적으로 유의하였다. 이상의 연구 결과를 종합해 볼 때 청각장애학생 들의 정서적 성향에 뉴로피드백 훈련이 긍정적인 효과를 미치는 것으로 검증되었다.

The underlying changes in biological processes that are associated with reported changes in mental and physical health in response to yoga breathing ($pr{\bar{a}}n{\bar{a}}y{\bar{a}}ma$) have not been systematically explored yet. In this study, the effects of a yoga breathing program on prefrontal EEG were tested with middle-aged women. Participants were collected as volunteers and controlled into two groups. Two channel EEG was recorded in the prefrontal region (Fp1, Fp2) from the yoga breathing group (n=17) and control group (n=17). QEEG quotients were transformed from the EEGs and analyzed by the ANOVAs on gain scores. As a result, ${\alpha}/{\delta}$ (left, right) and CQ (correlation quotient) for yoga breathing participants were significantly decreased compared to control group (p<.05). ${\alpha}/{\beta}_H+{\alpha}/{\delta}$ (left, right) were increased significantly (p<.05). For those significantly changed QEEG quotients, the interaction effects of Group x prefrontal alpha (${\alpha}$) and beta (${\beta}$) asymmetry were tested. Only the ${\alpha}$ asymmetry showed main effect on the gain score of ${\alpha}/{\beta}_H+{\alpha}/{\delta}$ (right) with F (1, 34)＝5.694 (p<.05). Pearson's correlation coefficient between ${\alpha}$ asymmetry and gain score of ${\alpha}/{\beta}_H+{\alpha}/{\delta}$ (right) was .374 (p<.05). The gain score of ${\alpha}/{\beta}_H+{\alpha}/{\delta}$ (right) was increased for the right ${\alpha}$ dominance of yoga breathing group. On the contrary it was decreased for the left ${\alpha}$ dominance of yoga breathing group as well as the control regardless of the dominance. The result of this study implies that yoga breathing increases stress resistance and is effective in the management of physical stress. Emotionally relaxed people may have greater instantaneous stress reduction after yoga breathing. Moreover, yoga breathing could be also beneficial for depressed who may be more vulnerable to stress.
