This study has been made to research effect of neurofeedback training on the Brain Quotient and baduk strength whose EEC data were obtained both before and after the neurofeedback training from 15th June, to 15th September in 2007. Brain waves were measured on the frontal lobes of subjects (30 baduk players - the experimental group 15 under neuroffedback training and the control group 15 subjects) and analyzed by calculating eight brain quotients characterizing behaviors of EEG rhythms effectively. The results of the analysis show that the experimental group has the higher indexes Attention Quotient(left) p=.041, (right)p=.007, Stress Quotient (left) p=.020, and Stress Quotient (right) p=.019 show statistically significant difference between two groups. The research data show that the experimental group have the higher average than the control group in Baduk strength examination p=.021 after the neuroffedback training. As the brain waves are adjusted by timeseries linear analysis, the brain function quotients can reflect the functional states of the brain.

This experimental study employs a pretest -posttest method concerning the integrated therapy of neurofeedback training, brain gymnastics, and oriental herbal tea effects on seniors living alone. The purpose of the study is to identify effects on brain functions and quality of life. The study participants included 23 seniors living alone (male 10, female 13), ranging in age from 65~90. The experiment lasted 8 weeks, from December 22, 2014, to February 28, 2015. The neurofeedback training utilized the 2 Channel neurofeedback system by Braintech Corporation and was conducted a total of 16 times over 8 weeks, having two sessions per week lasting for 30 minutes focusing on relaxation, concentration and memory. Brain gymnastics, developed by the Korean Science Institute of Psychiatry, ran for 30 minutes, twice a week for a total of 16 sessions administered over 8 weeks. Participants were required to drink 3 cups of oriental herbal tea developed according to Donguibogam for 8 weeks. The results of applying integrated therapy found positive effects on brain function resulting from changes in level of tension and anti-stress quotient. Quality of life, daily life basic measurements, and depression symptoms were significantly influenced by decreases in blood pressure and blood sugar. Results of this study find the integrated therapy of neurofeedback training, brain gymnastics, and oriental herbal tea can significantly enhance brain functions and quality of life within seniors living alone. Therefore integrated therapy involving neurofeedback, brain gymnastics, and oriental herbal tea is a necessary intervention to improve the quality of life of seniors living alone, and will improve the quality of life through healing both mind and body in a more practical and systematical manner.

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.

This study was to examine the effectiveness of brainwave training by observing the pre and post brainwave measurement results of about 48 (experimental group 24, comparative group24) subjects who have shown resistancestress and student assessment. The study took place at neuro-training center in P city I, during Jul. 2008 and Dec. 2008. As the brainwaves are adjusted by Brain Quotient, the tool used to measure the student assessment was 5Likert Scale questionnaire. The result confirmed the differences of both resistance stress quotient and student assessment. The result of the study suggest brainwave technique's possibility in positively affecting the subjects" resistance stress quotient and student assessment. This study revealed meaningful relation between neurofeedback training and stress among several categoties, while suggesting follow-up researches figuring out more detailed explanations.
