The purpose of the present study was to investigate personality type with evoked potentials. Teenage students(121 males, 69 females) tested Myers Briggs Type Indicator and raven like discrimination task by evoked potential. Raven like discrimination tasks were made of low, medium and high levels. Conclusively extraversion and introversion while accomplishing the raven like discrimination tasks, showed the significant difference between two groups in the power of concentration. M-Beta(middle beta), Gamma and H-Beta(high beta) were also appeared significant differences between two groups. The sensing and intuition type partially appeared the different tendency of two groups while accomplishing easy and medium of difficulty tasks. Thinking and Feeling type while accomplishing raven like discrimination tasks, showed difference of the concentration power and H-Beta at Fp1. But judgment and perception type did not appear the difference between two groups while accomplishing raven like discrimination tasks of low, medium, and high. These results implied that the personality type can be affected brain wave by evoked potentials.

The purpose of this study is to observe the changes of EEG signals in the process for solving the problems in concentration. In the experiments, subjects were given two tasks. The first task is to memorize the words after they used their own smart phone for ordinary commercial games and the second task is to memorize the words after they read a page of a p-book. In this paper, we present SMR waves and mid-beta waves to analyze from the EEG signals of the subjects because the waves are the EEG components related to concentration of human.

경제력 집중에 따른 부작용을 원천적으로 치유하거나 시장규율을 통하여 치유하기에는 오랜 시간이 필요하고 그 효과가 매우 더디다는 점이 인정된다. 또한, 계열사간 출자, 지급보증, 그리고 상호주는 이론상 어느 정도 긍정적인 측면을 갖는 것도 인정되므로, 원천적 치유가 가능한 시기까지 존재하는 경제적 부작용을 필요악으로 인정하고 그대로 둘 것이 아니라 한시적이나마 정부가 일정한 역할을 할 필요가 있다고 할 때, 그리고 현 자본시장의 감시 및 견제기능이 제대로 작동하지 않는다고 파악할 때 경제력 집중을 억제하기 위한 정책수단인 출자총액제한, 지금보증, 그리고 상호주에 대한 규제는 어느 정도 설득력을 갖는다.

Concentration is one of the most important factor in learning ability. It is important to improve concentration for learning ability. Most digital kids have been accustomed to addictive media like games since childhood, so traditional methods of teaching and learning has been difficult to give interests for them. Therefore introducing a new teaching methods was inevitable for students with low concentration. This is an experiment to prove the hypothesis that the concentration training by certain serious game would be helpful for improving students' concentration. Not only some serious games but also meditation by music was effective to improve concentration in the experiment. Average people is hard to immerge in meditation. but some serious games involve fun factors like curiosity, challenges, competitions and rewards. Games are not more negative to young people, will be helpful to society in various forms.

The purpose of this study was to investigate the effects of game-based-digital textbook on the basic arithmetic abilities and the task attention of students with mental retardation. To do this, 38 students with mental retardation participated and were assigned to the three groups. The first group only used the traditional text book, the second group only used the game-based-digital textbook, and the third group used both the traditional textbook and the game-based-digital textbook. The third group using both the traditional textbook and the game-based-digital textbook revealed more higher improvement than the other two groups in the basic arithmetic and the task attention.

Students with learning disability have difficulty with attention and academic achievement Music can be an effective tool to enhance level of participation. The purpose of this study is to examine how much can be structured to enhance the attention span and related academic skills needed to achieve educational goals. The study has implemented structured music therapy sessions for three middle school students with learning disability. They participated in 20 sessions which were 30 minutes in length for ten weeks. The implemented music therapy sessions were designed using songs, playing, and listening to music. In order to test their level of attention, Frankfurter Aufmerksamkeits-Inventar(FAIR) Attention Test is implemented and Conners' Comprehensive Teacher's Rating Scale(CTRS-10) are used on the week before and after music activities. Also videotaping is used so as to analyze how correctly they do their task and how the correctness is changed period by period and to evaluate how often for ten minutes they make an eye contact with their teacher. The conclusions of this study are as follows: Firstly, the organized music activities have a positive affection on improving the attention of three middle school students who have learning disabilities. Fair Attention Test shows that they can do their task with more accuracy than in the previous period. Secondly, three students of this study improved their attention and made an eye contact more often than before this study, which is revealed through the analysis of the pre and post test results evaluated by CTRS-10. The results of the study indicate that structured use of music in various level of activities can help students to enhance attention span and the related academic skills.

The purpose of this study was to investigate the visuo-spatial attention ability and the emotional perception ability of people across the normal range of the scores on the bipolar disorder scale. The Korean version of the Mood Disorder Questionnaire (K-MDQ) was used to measure the bipolar disorder tendency of normal people. A useful field of view (UFOV) task and an emotional perception task were used to measure visuo-spatial attention and emotional perception ability, respectively. The participants did not have any mental illness history or other medical problems. The participants were divided into three groups according to K-MDQ score (low, normal, and high), and their performances were compared. In the UFOV task, the high K-MDQ score group had lower level of performance than the other groups, suggesting that a high bipolar tendency is associated with reduction of visuo-spatial attention ability. In the emotional perception task, the group with the high K-MDQ score showed higher perception of negative emotion bias than the other groups, suggesting a high bipolar tendency to associate with reduction of emotional perception ability. These results suggest that visuo-spatial and emotional attention abilities are related with bipolar disorder tendency even in the normal population.

Objective : This study was conducted to find out the electrophysiological abnormalities of the patients with attention-deficit/hyperactivity disorder(abbr. ADHD) through identifying the profiles of the event-related potentials. Methods : Through measuring event-related potentials of 20 patients with ADHD and 16 normal control children using Oddball paradigm, we evaluated the latencies and amplitudes of each wave form. Results : In the group older than 9 years old, the latencies that reflect selective attention and discriminative capacity of the patients with ADHD were significantly longer than those of normal controls, which suggests that patients with ADHD be more distractible to non-significant stimuli and that they be in lark of sustained attention and discriminative ability. Conclusions : We concluded that the patients with ADHD are more distractible to trivial stimuli than normal children but they lack discriminative, sustained ability of attention.
