본 연구는 2010년 2월부터 2010년 7월까지 B. 뇌 훈련 센터에 자기주도학습 능력 향상을 위하여 방문한 내담자 60명(실험군 30명, 대조군 30명)의 뇌파를 검사하여 뉴로피드백 훈련 전과 훈련 후의 뇌기능과 자기주도학습 능력 변화를 보고자 하였다. 자기주도학습 능력에 영향을 미치는 특정한 뇌 기능의 훈련 전과 후의 결과를 시계열 선형분석으로 비교하였다. 연구의 결과로는 자기조절지수, 훈련모드, 자기주도학습 능력에서 집단 간에 유의미한 차이가 나타났다. 이는 뉴로피드백의 기술을 적용한 뇌 훈련은 자기조절지수와 자기주도학습 능력에 긍정적인 영향을 미친다고 볼 수 있겠다.

This research aims to assess whether neurofeedback training can reduce theta waves in adolescents. The experiment was conducted on 35 early youths living in Gyeonggi-do at youth counseling centers during April-October. According to circumstances and opinions of participants in the pre-brain analysis, they were classified into a non-training group (A), 12-week training group (B), and 24-week training group (C), containing 10, 15, and 10 members, respectively. EEG measurement and neurofeedback training was performed using the prefrontal 2-channel NeuroharmonyS and Brain Optimization program. EEG data was processed utilizing Brain Analysis ver1.3. Deducted data was converted to SPSS 21.0 to enable statistical processing. As a strategy to reduce theta through the Beta increase training, we applied the appropriate Alpha, SMR, Beta low reward training to the individual. Study results confirmed that theta waves of adolescents decreased through the prefrontal neurofeedback training. Groups (B) and (C) exhibited a greater decrease in theta waves compared with the control group.

The purpose of this study was to verify the effect of Neurofeedback training on adolescence groups that are different in Age. The experiment was carried out with 90 students who living in Kyonggi-do. From Nov. 2009 to Mar. 2010, each were under training about 20-25 times, 2-3 times a week, during 20 to 50 minutes, was conducted by limiting training. Statistical data collected were processed with the SPSS 12.0. For the purposes of t-test showed that differences in the effects of age. The result, the effects of Neurofeedback training on age difference groups were reflected characteristics of brain's development in adolescence. The most effective showed in middle school students. Also, Significant effects of Neuofeedback training that were confirmed in attention quotient, Activation quotient, Stress resistence quotient.

This Convergence study aimed to investigate the effects of changing brainwave neurofeedback training on life stress and depression in female college students. Twenty-six of the subjects were selected into the experimental group and the control group respectively intervention for 8 weeks, the following results were obtained. First, experimental group and control group presented statistical significant difference before and after intervention on life stress, and life stress in experimental group was statistical significantly decreased than control group. Second, experimental group and control group presented statistical significant difference before and after intervention on depression, and depression in experimental group was statistically significantly decreased than control group. The results obtained from this study expect us that applying the neurofeedback training for the decrease of life stress and depression, has a positive effect.

This study was to examine the effectiveness of neurofeedback training by observing the pre and post brainwave measurement results of about 39(experimental group 25, comparative group 14) student who have shown emotional. The study was examined at S city M dong A hearing impairments student, from Mar. 2009 and to Feb. 2010. The training took place two times a week, for about 40 minutes per session. The tool used to meas ure the psychological reaction was POMS (Profile of Mood State). First, the result confirmed the differences of both attention quotient(L R) and resistance stress quotient(L R). Second,, the results of the analysis show mood state. Therefore, the result of the study shows that there is possibility that NeuroFeedback technique might be positively affecting emotional of the hearing impairments student.

Objectives: Insomnia is one of the most prevalent sleep disorders. Recent studies suggest that cognitive and physical arousal play an important role in the generation of primary insomnia. Studies have also shown that information processing disorders due to cortical hyperactivity might interfere with normal sleep onset and sleep continuity. Therefore, focusing on central nervous system arousal and normalizing the information process have become current topics of interest. It has been well known that neurofeedback can reduce the brain hyperarousal by modulating patients' brain waves during a sequence of behavior therapy. The purpose of this study was to investigate effects of neurofeedback therapy on electroencephalography (EEG) characteristics in patients with primary insomnia. Methods: Thirteen subjects who met the criteria for an insomnia diagnosis and 14 control subjects who were matched on sex and age were included. Neurofeedback and sham treatments were performed in a random order for 30 minutes, respectively. EEG spectral power analyses were performed to quantify effects of the neurofeedback therapy on brain wave forms. Results: In patients with primary insomnia, relative spectral theta and sigma power during a therapeutic neurofeedback session were significantly lower than during a sham session ($13.9{\pm}2.6$ vs. $12.2{\pm}3.8$ and $3.6{\pm}0.9$ vs. $3.2{\pm}1.0$ in %, respectively; p < 0.05). There were no statistically significant changes in other EEG spectral bands. Conclusion: For the first time in Korea, EEG spectral power in the theta band was found to increase when a neurofeedback session was applied to patients with insomnia. This outcome might provide some insight into new interventions for improving sleep onset. However, the treatment response of insomniacs was not precisely evaluated due to limitations of the current pilot study, which requires follow-up studies with larger samples in the future.

This study aims to identify the effect of neurofeedback training by observing the pre and post brainwave measurement results of about 60(experimental group 30, control group 30) subjects who have shown self directed learning ability. The study took place at neuro-training center B, in between the months of Jan. 2010 and Jul. 2010. As the brainwaves are adjusted by timeseries linear analysis. The result confirmed the differences of both self regulation quotient, training protocol, and questionnaire. The result of the study suggest neurofeedback technique's possibility in positively affecting the subjects' self directed learning ability.

Recently, many people have suffered from insomnia, labor loss, cognitive decline, and mental illness. The solution to this problem is almost entirely cognitive therapy or medication, but it is not recommended in the long term due to side effects and dependency problems. Therefore, in this paper, we propose a neuro feedback system based on portable EEG that helps induce sleeping. We design and evaluate the EEG classifier, which is the most important function to implement the system, and propose an optimized classifier modeling method for various factors that can affect performance. When using the proposed classifier, we could distinguish 97.9% of awakening and sleep phase in portable EEG.

본 논문은 동적 3-D 뉴로 시스템(A Dynamic 3-D Neuro System)모델을 이용하여 오프라인 필기체 숫자 인식 실험을 하였다. 3-D 뉴로 시스템 모델을 사용함으로써 기존에 교육된 정보를 유지하면서 새로운 정보를 추가할 수 있는 추가학습이 가능했고, 동일한 범주의 정보에 대해서는 반복교육 횟수에 따라 교육정도가 점점 누적되는 반복교육이 가능했다. 교육과정을 통해 누적된 정보로부터 일반화된 패턴(Generalized Pattern)을 도출해 인식시 사용할 수 있었다. 패턴 인식기는 피드백루틴을 통해 미지의 입력이미지를 원형이미지로 복원한 후, 그 결과 데이터를 사용하여 문자를 인식하도록 동작한다. NIST의 MNIST 데이터베이스를 사용해 실험을 하였고, 결과로 $99.0\%$의 정인식률을 얻었다.
