  • 본 연구는 집중력, 기억력 및 학습 능력의 뇌기능 증진을 위한 의식적인 손 운동에 관련된 연구이다. 우선 효과적인 재활을 위한 손가락 운동 패턴을 연구하였다. 단순한 손가락 운동(Simple Finger Movement ; SFM) 패턴과 의식적인 손가락 운동(Intentional Finger Movement ; IFM)패턴을 비교하였다. 다음으로 각각 두 패턴 운동을 시켜 피험자의 집중력과 학습 능력의 증진을 검증하고자 한다. SFM 패턴과 IFM 패턴의 비교와 집중력과 학습 능력의 증진의 검증은 뇌파(mid $\alpha$파)를 이용하였다. 실험은 먼저 SFM 패턴의 운동을 시키고 다음에 IFM 패턴의 운동을 시키는 실험을 하였다. 결과적으로 IFM 패턴에서 mid $\alpha$ 파의 증가가 이루어졌음을 측정함으로써, IFM 패턴이 뇌의 집중력과 학습 능력을 증진시킨다는 결과를 얻었다.

  • This study was to examine the effectiveness of prefrontal Neurofeedback training by observing the pre and post brainwave measurement results of about W kindergarten kids 52 (experimental group 26. comparative group 26) subjects who have shown brain quotient and master ability, in between the months of Mar. 2010 and Nov. 2010. As the brainwaves are adjusted by timeseries linear analysis, the result confirmed the differences of both brain quotient and master ability. The result of the study suggest Neurofeedback technique's possibility in positively affecting the subjects' brain quotient and master ability.

  • This research is about the effect on children's brain before and after learning Baduk. The research was performed on 20 pupils attending I Baduk school with the contrast group of 20 pupils who did not take Baduk instruction. The pre-test on the brain waves before learning Baduk were measured from October 27, 2008 to November 7, 2008 and the post-test on the brainwaves after learning Baduk were measured from November 2, 2009 to November 4, 2009. The result confirmed the differences of both resistance activity quotient and emotion quotient. The result of the study suggest baduk study possibility in positively affecting the subjects' brain activation and emotion.

  • World Health Organization reveals its plan for listing 'Gaming Disorder' on the 11th International Disease Codes (ICD-11) in 2018 and it opens hot debate among scholars on its validity and timeliness. Korea, however, seems to have avoided the issue without appropriate academic refutation. In this paper, we review past academic studies related to game addiction or disorder focused on their validity of disorder measurement tools, research designs and the effect of neuroimaging studies. This analysis reveals that excessive use of gaming is not sufficient to register it as a disease and there is a risk of stigmatizing healthy gamers.

  • This study intends to examine the effects of education using robot on computational thinking and attitudes according to left and right brain preference. To execute the study, 17 elementary students at A youth training center in Seoul were selected to participate in the education. And the mean difference was analyzed using matched pair t-test and Mann-Whitey U test. As a result, after participating in the education, there was some statistical significance found in the scores to test student's computational thinking, but not statistical significance on the attitudes. Furthermore, there was no significance found in computational thinking or attitude according to the left and right brain preference. The purpose of this study can be found in that it expands the understanding of education using robot by verifying the efficacy and analyzing differences according to left and right brain preference.

  • This study is about how differ math anxiety according to the features of brain preference. In order to solve questions, BPI test and math anxiety test were done to high school students in the second grade. The test sheets were analyzed by ANOVA and MANOVA using SPSS 14.0. The result was found out that math anxiety was high in the order of left-brain preferences, both-brain preferences, and right-brain preferences. High level of math anxiety among students with right-brain preferences seem to be influenced by the right brain which prefers emotional features. Therefore, students need to stimulate their left brain by writing and reading something a lot when they solve math questions. Also, teachers can lessen math anxiety of students by give them opportunities to solve step-by-step questions, using various visual teaching materials promoting students' reasoning ability which can help them solve questions in a systematic and analytic way.

  • In this study, a meta-analysis was conducted to investigate the effect of community-based rehabilitation on patients with brain injury by ICF factor in previous studies and examine the application of recent community-based rehabilitation program. Total 15 articles that satisfied the selection criteria were divided by ICF factors to obtain the effect size. Homogeneity and publication bias were tested for those selected papers. As a result, the overall effect size of community-based rehabilitation was 0.22; the effect size by physical function and structure among the ICF factors came to be 0.21; and the effect size of activity and participation was 0.20, indicating a small effect size. The studies involved in a meta-analysis were considered as the absence of heterogeneity and publication bias, which indicates that the results of this study are subjectively reliable. These results well explained the level of change on ICF factors, especially physical function and structure, activity and participation, in other words, the intervention effect of community-based rehabilitation on patients with brain injury.

  • We applied fMRI to examine brain activation at intentionality detection (ID) task. The main purpose of this study was to explore whether brain activation regions involved in intentionality detection (known as the basic mechanism of theory of mind) differ or not, according to prior instruction. Left uncus, superior temporal gyrus and right inferior occipital gyrus, supramarginal gyrus, inferior parietal lobule, thalamus (medial dorsal nucleus), and precuneus were activated with prior instruction. In contrast, ID task with no instruction activated merely inferior parietal lobule and superior parietal lobule. Common activated area between the two instruction conditions was inferiordparietal lobule. Our results suggest thar prior instruction activated ID-related brain regions more explicitly. furtherdinvestigations would be loused on spontaneity of intentionality detector and characteristic of participants.

  • Purpose : Instead of conventional two-dimensional (2-D) visual stimuli, three-dimensional (3-D) visual stimuli with stereoscopic vision were employed for the study of functional Magnetic Resonance Imaging (f-MRI). In this paper f-MRI with 3-D visual stimuli is investigated in comparison with f-MRI with 2-D visual stimuli. Materials and Methods : The anaglyph which generates stereoscopic vision by viewing color coded images with red-blue glasses is used for 3-D visual stimuli. Two-dimensional visual stimuli are also used for comparison. For healthy volunteers, f-MRI experiments were performed with 2-D and 3-D visual stimuli at 3.0 Tesla MRI system. Results : Occipital lobes were activated by the 3-D visual stimuli similarly as in the f-MRI with the conventional 2-D visual stimuli. The activated regions by the 3-D visual stimuli were, however, larger than those by the 2-D visual stimuli by $18\%$. Conclusion : Stereoscopic vision is the basis of the three-dimensional human perception. In this paper 3-D visual stimuli were applied using the anaglyph. Functional MRI was performed with 2-D and 3-D visual stimuli at 3.0 Tesla whole body MRI system. The occipital lobes activated by the 3-D visual stimuli appeared larger than those by the 2-D visual stimuli by about $18\%$. This is due to the more complex character of the 3-D human vision compared to 2-D vision. The f-MRI with 3-D visual stimuli may be useful in various fields using 3-D human vision such as virtual reality, 3-D display, and 3-D multimedia contents.

  • In this thesis, we made a sheet to improve the concentration of study. To demonstrate the improvement in the concentration of study, we obtained functional magnetic resonance imaging (fMRI), which has superior time resolution and measures brain noninvasively by using intrinsic contrast agent. As a result of Brainwave measurement, we could verify the blood flow's activate in the nearby frontal lobe related to memory process and noticeable ratio change in absolute alpha wave and beta wave after the analysis of Brainwave measurement. fMRI ascertains the physiological function of the brain and is being used to prevent the trouble medically that can be caused before and after the operation. For the visibility of cranial nerve network, many researches will be carried out to develope the product which is related to brain like concentration of study.
