This study was to examine the correlation of Personality and EEG. Personality test and EEG of the 40 team leader of a business enterprise were carried out at the same time and the correlation of test results were analyzed. Personality test was done by Big 5 and brain waves were measured by 2-Channel EEG System at Fp1 and Fp2. The analysis showed a positive correlation between the Big 5 agreeableness and SRQ(Self Regulation Quotient) relaxation status which is related with alpha rhythm, and showed a negative correlation between the Big 5 openness and SRQ concentration status which is related with low_beta rhythm. It means that the personality is closely correlated with human brain cortex activation and can be checked by brainwave analysis.

Purpose: This study aimed to measure COVID-19 stress and the quantitative electroencephalography (QEEG) stress quotient and identify the coping styles of face-to-face service industry employees during the COVID-19 pandemic. Methods: This cross-sectional study administered structured questionnaires consisting of sections on general characteristics, COVID-19 stress, and coping style for stress to 21 face-to-face service industry employees between April 1 and April 18, 2021. The physical tension & stress quotient and psychological distraction & stress quotient were measured in the prefrontal lobe with QEEG. Results: Emotional easiness (r=.62, p=.002) and escape-avoidance (r=.55, p=.009) as a passive coping style were associated with COVID-19 stress, and seeking social support as an active coping style was associated with the left physical tension & stress quotient (r=.47, p=.031). Conclusion: These findings provide evidence regarding the objective status of the mental health of face-to-face service industry employees using both a self-reported scale and neuroscientific indicators, including brain quotients.

Morbidity, mortality, mental health and problem behavior appears to be high in adolescence, but there is no proper intervention. This quasi-experimental study examined the effects of the neurofeedback training on the general health status, mental health and problem behavior, and the brain function quotient through structured questionnaires and brain waves of 11 high school students (experimental group 5, control group 6). The study was conducted at I high school in Seoul from September to December, 2012. The subjects participated in the neurofeedback training twice a week for a total of 20 sessions by trained researcher. The data was analyzed using paired t-test or Wilcoxon signed rank test depending on the normality using SPSS 20.0. Significant improvement was observed in the emotion quotient and stress resistance quotient (left, right) among the brain function quotient, but not in the general health status, mental health and problem behavior.

This study examined the influence of a Mindfulness Based Compassion Meditation Program on the brain activation and stress of elderly women who experienced loss of spouse using 2 channel EEG (Electroencephalography). The total number of subjects was 60, consisting of elderly women aged from 65~75years of in Y county; 30 in the experimental group and 30 in the control group who were checked by EEG before and after the study. The study was conducted from August to November, 2015. The Mindfulness Based Compassion Meditation Program was designed for the convergence of body and mind integration with compassion meditation for the purpose of developing love, sympathy, and compassion. The treatment was conducted once a week, for 60 minutes at a time, over a period of 16 weeks. The results in the experimental group showed an increase in the Activity Quotient (ATQ) Rt(82.51/85.83, p<.013) and AntiStress Quotient (ASQ) Lt (74.711/71.17, p<.050). The Activity Quotient shows the mental function and behavior tendency in the brain, while the AntiStress Quotient shows the state of physical and mental relaxation. The Mindfulness Based Compassion Meditation Program was shown to influence the brain activation and stress of the elderly women using the practical application of neuroscience.

This study aims to identify the mediating effect of school satisfaction in the effect of self-esteem on resilience, and to examine the relationship between brain function quotient and resilience. In this descriptive study, questionnaires and brainwaves were collected from 145 female high school students in Seoul from November 22 to December 23, 2012. Data were analyzed by Pearson's correlation coefficient and three-step mediated regression analysis using SPSS 21.0. Among brain function quotients, stress resistance quotient were highly correlated with resilience, and both attention and brain quotient were significantly correlated with resilience. Moreover, school satisfaction showed the mediating effect in the effect of self-esteem on resilience. The findings suggest that brain function quotient, in specific, stress resistance quotient, should be considered in studies regarding resilience. Furthermore, predictor variables of resilience such as self-esteem and school satisfaction should be considered for preventive and therapeutic intervention to reduce various maladaptive problems in adolescents.

The purpose of this study was to determine the relationships between fatigue, stress resistance and emotion in middle aged women under the developmental crisis using a brain wave measurement which is a cranial physiological index. From March 2005 to June 2009, women aged between 35 and 65 (N=4402) who volunteered for a brain wave test at the KRIJUS( Korea Research Institute of Jungshin Science) were monitored the brain function quotient (tension degree, anti-stress quotient and emotional quotient). Correlation and time-series linear analysis revealed significantly the relationships between fatigue, stress resistance and emotion. Also, according to the emotional propensity, cheerful propensity was higher in the cheerful and depressed propensity, positive propensity was higher in the positive and negative propensity, during the whole test, cheerful and positive propensity was higher. Therefore, it is necessary to increase the quality of life by decreasing fatigue and stress level of the middle-aged women to maintain and increase their individual health and the better family relationship.

The purpose of this study is to examine the relationship between the Minnesota Multiphasic Personality Inventory(MMPI-2) clinical scales and the self-regulation quotient of the brain quotient. The test in this study was performed by 41 adults over 20 years old and was done using the MMPI-2, which is a self-reporting method. EEG was performed using a 2-channel EEG System at Fp1 and Fp2. The analysis showed a negative correlation between scale 2(D), which is the MMPI-2 clinical scale, and the SRQ(Self Regulation Quotient) relaxation status, which is the related alpha rhythm. Scale3(Hy) showed a positive correlation with the SRQ concentration status and low ${\beta}$ rhythm. Scale7 in the MMPI-2 clinical scales showed a negative correlation with the SRQ relaxation status, which is the alpha rhythm. This means that MMPI-2 and SRQ can be used complementarily in the field of counseling. These results could be interpreted in three ways. First, people with depression are sensitive to other people's attention and evaluation. Therefore, they tend to expend a lot of energy when forming interpersonal relationships, and if they do not learn to relax, their fatigue can easily be increased. Second, people who seek other people's interest and have a cheerful spirit are considered to be highly active. Third, highly stressed people with anxiety and tension seem to easily become tired and their irritation and discomfort may be increased in consequence.

Brainwave can be the most effective means of detecting the state of the brain that changes moment by moment. Since brain has closed relations with hormones which are a foundation of metabolism, it needs to examine closely the mutual relationship between brainwave and hormone. We examined the possibility to find out such information about metabolism by comparing brainwave with cortisol hormone. The major variables are anti-stress quotient of brainwave and cortisol density which give stress information of the working women, to measure from March 3 to May 28, 2007. To find out the relationship between them, we performed such statistical analysis about the before and after of brainwave training as t-test, correlational analysis and regression analysis. We obtained following results: First, considerable changes of variables is shown by brain-wave training. Second, there exist a correlation between variables. Third, according to regression analysis, influence between variables is verified. Thus, we found that stress information of hormone analytical level can be obtined only through brainwave analysis.
