Managerial intuition is a well-recognized cognitive ability but still poorly understood for the purpose of developing effective decision support systems. this research investigates whether the differences in accuracy of "time series forecasting" are related to the differences in one's cognitive style, using statistical test The hypotheses established in the research model did not have positive correlation The lack of correlation between "cognitive style and physiological measures" and accuracy in forecasting may be caused by uncontrolled external variable. Thus, further analyses on physiological characteristics and brainwaves are needed. The approaches such as neural network and data mining are proposed.

The purpose of this study was to analyze the affection of plan configuration on human emotion using Virtual Reality. A total of four different plan configuration was selected according to the prior study and built using Virtual Reality. The EEG was measured and then calculated using FFT to measure human emotion in different plan configurations. The measurements were shown to lead there was a significant statistical difference in four types of brainwaves between the plan types(p<0.05). This indicates that there is a possibility of plan configuration may exacerbate psychological disorder among single-person household and suggests that it is possible to counteract those stress among single-person household by changing the plan configuration in the earlier designing stage.

Purpose: Breathing can be controlled either unconsciously or consciously. In Asian countries, various conscious breathing-control techniques have been practiced for many years to promote health and wellbeing. However, the exact mechanism underlying these techniques has not yet been established. The purpose of this study is to explore the physiological mechanism explaining how conscious breathing control could affect the autonomic nervous system, brain activity, and mental changes. Methods: The coupling phenomenon among breathing rhythm, heart rate variability, and brain waves was explored theoretically based on the research hypothesis and a review of the literature. Results: Respiratory sinus arrhythmia is a well-known phenomenon in which heart rate changes to become synchronized with breathing: inhalation increases heart rate and exhalation decreases it. HRV BFB training depends on conscious breathing control. During coherent sinusoidal heart rate changes, brain ${\alpha}$ waves could be enhanced. An increase in ${\alpha}$ waves was also found and the synchronicity between heart beat rhythm and brain wave became strengthened during meditation. Conclusion: In addition to the effect of emotion on breathing patterns, conscious breathing could change heart beat rhythms and brainwaves, and subsequently affect emotional status.

There are a lot of games which have good benefits in the game genre such as serious game. In this paper we implement an serious game for increasing intensive power by calculating the index of the intensive power based on EEG signal. First we explain the definition of the EEG and the classification of the brainwaves and we depict the method for increasing the intensive power. Then we apply the index of the intensive power to the game production to train the intensive power. At last we make an experiment on the effect of an game which increases the intensive power and the analysis shows the increase of the intensive power.

Objectives: In this case report, we will show the effectiveness of herbal medicine with neurofeedback treatment on social phobia. Methods: First, we diagnosed the patient by interview and questionnaire as having social phobia and suffering from anxiety, shaking and palpitation in public places and fear to meet new people. Beside, we examined the pattern of brainwaves by QEEG-8 system. Second, we treated the patient by herbal medicine with neurofeedback treatment for 4 months. Then we conducted new assessments by SCL-90-R, BDI, BAI and QEEG-8 system. Results: The patient's psychological and physiological symptoms were significantly improved. Conclusions: Herbal medicine with neurofeedback can be effective in the treatment of social phobia. Especially, it can be helpful to improve the patient's sensitivity to its physiological symptoms.

This study was to examine the effectiveness of BGA education program by observing the pre and post brainwave measurement results of about W, S city kindergarten kids 200 (experimental group 100. comparative group 100) subjects who have shown brain quotient, in between the months of Jul. 2010 and Dec. 2010. As the brainwaves are adjusted by timeseries linear analysis, the result confirmed the differences of both brain quotient. The result of the study suggest BGA education program possibility in positively affecting the subjects' brain development.

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.

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.

To improve the quality of life, wireless ad-hoc network technologies are considered as one of the key research areas in computer science and healthcare application industries. The ubiquitous healthcare systems also provide alerting mechanisms against ill conditions in real time. This minimizes the need for care-givers and helps the chronically ill and elderly to survive. For the application of the system, supporting the efficient and proper network system is essential. So in this paper, I suggest some hospital network environments including patient mobile nodes continuously sending brainwaves to the server of the hospital area. Finally, the network systems are simulated by OPnet simulator and evaluate the performance among various mobility of the mobile nodes and topologies of the network for the efficient system.
