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.

This study examined for which socio-economic difference effects on brain function and Problem behavior syndrome in children. About a children with no disorders, diseases or cognitive dysfunction-30 were from LIC children and another 30, from MC ones, the study was conducted by measuring and analyzing the data using brain function analysis and K-CBCL from January to April, 2013. The results of the study are as follows. First, it was found that the ratio of LIC's theta(${\Theta}$) and SMR waves and that of delta(${\delta}$), high beta(${\beta}h$), alpha(${\alpha}$) and low beta(${\beta}l$) waves showed significantly higher values than MC children. Second, concerning the symptoms of child behavioral problems, LIC showed significantly higher values than MC children in symptoms of the body, depression and anxiety, social immaturity, thinking problems, attention problems, aggression, internalization, externalization, overall behavioral problems, and emotional instability. MC children showed significantly higher values than LIC chidren in symptoms of social, academic-performance, total social skills. In conclusion, the significant difference of the brain functions and the symptoms of child behavioral problems between LIC and MC children showed that the socio-ecnomic difference has an influence on the same functions and symptoms above.

This study was to examine the correlation between the brain function of adult suffering from obesity and the level of their obesity based on brainwave measurements. Based on the result of Body Composition Analysis (BCA) examination, population of 651 overweight pupils was chosen from June 2011 to December of 2012 in S city, I hospital. These patients were measured by timeseries linear analysis for their brain function and observed via brainwave activities. The results have been thus far; first, as their BMI (Body Mass Index) and level of obesity (body fat percentage) were higher, degree of mental stress and resistant to stress marked lower. These results prove that by managing the stress resistant ability and attention ability, self-controlling ability, one can expect a positive effect on finding a methods to ease the obese-related problems.

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.

In this paper, the characteristics of online game addiction have been analyzed using fMRI. The fMRI images are taken from six target subjects who are around 20 years old, right-handed, and undergraduate male students with online game stimulations. The images are processed using SPM5, and statistical analysis showed following characteristics. First, online game stimuli produces an activation in BA18 of brain, and the Pearson correlation coefficient between the activation intensity of BA18 area and the addiction index value is very highly as .94. Second, the Pearson correlation coefficient is .75 between addiction index of subjects and activation index of the mesencephalon. From these observations, we found that the online game stimuli were processed as visual stimuli by subjects' brain, and the subject's brain with bigger addiction index processes more actively from the online game stimuli. Also, the online game stimuli activate the mesolimbic system, and therefore these findings may contribute for comparing the mechanism between general addiction and online game addiction.

This study was to examine the effectiveness of neurofeedback training by observing the pre and post brainwave measurement results of about 52 (experimental group 26. comparative group 26) subjects who have shown self regulation ability. The study took place at neuro-training center B, in between the months of Jan. 2008 and Dec. 2008. As the brainwaves are adjusted by timeseries linear analysis, the tool used to measure the self regulation ability was 5 Likert Scale questionnaire. The result confirmed the differences of both self regulation quotient, training protocol, upper deviation and questionnaire. The result of the study suggest prefrontal lobe neurofeedback technique's possibility in positively affecting the subjects' self regulation ability. This result suggested that follow-up researches should be figuring out more detailed explanations for journal of adolescent welfare.

This study is analized with how Dance as a healing art influence to elderly women's brain function measured by 2 channel system EEG(Electroencephalogram). The objects in this study are 60 aged over 65years in K city. The study started from March to July in 2013. The treatment was conducted by ones a week, 60minutes a time for 16 weeks. Participants are 30 of the experimental group and 30 of the control group checked by EEG before and after treatment. The result in experimental group is indicated as followed. The Basic Rhythm Quotient Lt(79.11/89.56, p<.015), wave length Rt((8.33/9.37, p<.003), amplitude Lt(39.87/47.19, p<.006), amplitude Rt(40.09/49.87, p<.000) did show statistically higher score after treatment.

본 연구는 발달적 위기에 놓여있는 중년여성의 피로도와 스트레스 저항력 그리고 정서와의 상관관계를 알아보기 위하여 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 분석해 보고자 하였다. 2005년 3월부터 2009년 6월까지 한국정신과학연구소에 뇌파 측정을 의뢰한 우리나라 중년여성 4403명(35세~65세)을 기준으로 선정된 뇌기능 지수(긴장도, 항스트레스지수, 정서지수)를 시계열 선형분석과 상관분석으로 한 결과 중년여성의 피로도, 스트레스 저항력 그리고 정서에는 밀접한 관계가 있었다. 그러므로 사회적으로나 가정적으로 성숙하고 책임감 있는 중년여성의 역할이 필요한 현대사회에서, 중년기의 심리적 생리적 문제에 적극적으로 대처하는 것이 개인생활은 물론 가족의 원만한 기능과 안녕을 유지, 증진하는데 반드시 필요하다.

Objective : The purpose of this study was to investigate the effects of virtual reality-based activities of daily living (ADL) training on ADL and rehabilitative motivation in patients with traumatic brain injury. Methods : This study was performed using a pre-post design with seven traumatically brain injured patients. Subjects were subjected to virtual reality-based ADL training for 30 minutes a day, 2 to 3 times a week for 4 weeks. Evaluation was conducted before and after the intervention using the Korean Modified Barthel Index (K-MBI), Cognitive Functional Independence Measure (C-FIM), and Volitional Questionnaire (VQ). Changes before and after intervention were analyzed by Wilcoxon signed-rank test, and correlations were analyzed using Spearman's coefficient. Results : After intervention, patients with traumatic brain injury showed significant improvements in K-MBI (p<.05). There was no significant change in total C-FIM score and VQ score (p>.05). Total C-FIM score correlated significantly with VQ score (p<.05, r=.755). The social cognition domain of C-FIM had a significant correlation with VQ score (p<.05, r=826). Conclusions : Virtual reality-based ADL training can improve ADL performance, but further research is needed to determine whether improvements in social cognition and rehabilitative motivation are possible.
