The purpose of this research was to compare the concentration variation between the sport talented children who have been applied with a sport program and the ordinary children who did not. The experiment group was composed of 59(male:32, female:27) sport talented children who were selected from the center of Busan University sport talent in April 2010. The control group was made up of 148 students who participated in 3 elementary schools located in Busan. Among these ordinary students 80 participants were finally used, as some of the students were excluded who were playing as athlete or studying in Science gifted program, FAIR concentration test sheet was used for this study, which was reformed for Korean version by Oh(2002). Covariance analysis was applied for using SAS 9.1 package, and the following conclusions were drawn. First, both the sport talented group and ordinary group of FAIR concentration's 3 subfactors were improved significantly after 8 months. Second, no difference between the sport talent group and ordinary group were found in the variations of post test of concentration's 3 subfactors. Especially there was no difference among groups in oneway-ANOVA using data of post test.

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.

In this paper, we analyze the interaction features using eye-tracker and the characteristics of attention concentration of children with intellectual disabilities, and present gamification elements that can be used when designing digital contents for them. For children with quadriplegic cerebral palsy, eye-trackers will increase the accessibility of digital contents. Foreground gamification can be used for selective attention concentration, background gamification and intrinsic motivation to sustain attention concentration, and foreground gamification and extrinsic motivation for mobility.

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.

The stability behavior of the cantilever beam carrying several masses and subjected to a follower force at its free end is investigated. The effects of the location and the mass ratio of the concentrated masses on the stability of the system are discussed. An optimal location of the concentrated mass is determined to give maximum critical follower force. Discontinuities of the flutter load are observed for the system with more than two concentrated masses.

In this paper, the effect of neurofeedback training program on attention ability of ADHD children is studied. The main concept of a neurofeedback training program is a robot control with brain wave. To do this, Mindset(neurosky, ltd) was used as a brain wave measurement and lego NXT was used to a robot kit. The developed brain wave training program has a 12 chapter. Students meet a problem situation and they invent and make a problem solving robot with NXT kits. After that, they control the their own robot by their brain wave. Developed program was applied to 8 student who live in chunan area. To monitor a change of attention ability, attention behavior checklist, K-CBCL, CTRS-R, ADS were used. These checklist were recorded with before and after the program. The result shows that student attention ability is increase after the program in the most of the checklist.

Neuro-feedback is a technology that can identify your brain state and you can intentionally change your brain state. People with attention deficit and hyperactivity disorder need this technology but existing neuro-feedback training has a problem, which is not interesting and maintains a static state for a long time. In this paper, we proposed and implemented a neuro-feedback game that combines neuro-feedback and gun-shooting games to enhance concentration training. The neuro-feedback game has been implemented with the design of EEG measurement system, game controller and gamesoft. We hope that this study will be useful for people suffering from attention deficit and hyperactivity disorder.

In this paper, we measured and analyzed the EEG signals related to the relativity between musical stimuli and human concentration for memorization. In our experiments, the subjects carried out the tasks related to human memorization exposing to musical stimuli and the tasks are to memorize the english words. We used two kinds of musical stimuli, one is a sedative tendency music and the other is a stimulative tendency music. We presented the results that are analyzed as the EEG signals by frequency bands, respectively.

The study was to find out the effects of computer game and stretching on muscle tone and concentration. The subjects were 30 adults, who were divided into 15 stretching group and 15 control group after applying computer game for 120 minutes. The subjects measured muscle tone and concentration before experiment, the same measurements were made before and after applying the stretching. The muscle tone was respectively measured after 60 minutes and 120 minutes of computer game. The results showed that muscle tone increased significantly after 60 minutes and 120 minutes of computer game, and significantly decreased in the stretching intervention group. Concentration increased significantly after computer game, but there was no significant difference after application of stretching. In this study, computer game increased muscle tone and concentration, and stretching decreased increased muscle tone. Therefore, proper stretching after computer games will reduce musculoskeletal diseases caused by increased muscle tone, and development of appropriate game contents will be an effective tool for concentration training.

지난해 12월 국회를 통과한 개정 공정거래법은 기업결합규제의 개선, 과징금의 상향을 통한 카르텔 억지력의 강화, 역외적용의 근거규정 신설과 손해배상의 활성화 등 주요 내용을 담고 있다. 특히 경제력집중억제와 관련해서는 2003년 시장개혁 3개년 로드맵에 기초하여 공정위가 제시한 원안대로 출자총액제한의 존치, 금융계열사의 의결권제한 강화 등이 이루어 졌다. 아쉬운 점은 경제력집중억제에 관한 이슈들이 객관적인 입장에서 심도 있게 다루어지기보다는 여야간, 당정간, 부처간, 정부와 재계간 이해관계의 차이만을 주로 반영하고 있다는 사실이다. 그간 이 문제에 관한 학계에서의 진지한 논의가 결여되어 있던 것도 이러한 난맥상을 더욱 심화시켰음은 물론이다. 법률의 개정으로 모든 쟁점이 해소된 것은 아니므로, 차제에 특히 경제력집중억제, 손해배상의 활성화 및 역외 적용과 관련하여 남겨진 향후 과제를 살펴보는 것은 중요한 의미를 갖는다.
