군에서의 경계근무는 방위 임무에 있어 아무리 강조해도 부족할 정도로 중요한 업무이지만, 인간이라는 한계 때문에 어쩔수 없이 소홀히 되어지는 부분이 있다. 이에 본 논문에서는 뇌파를 사용하여 경계병의 졸음을 검출하는 시스템을 제안하였다. 이 시스템은 IoT를 기반으로 설계되었으며, 주요기능으로는 뇌파 측정 기능, 신원 확인 기능, 졸음 판별 표시 기능, 실시간 뇌파 전송 기능 등이 있다. 현재 각 기능에 대한 구체적인 방법들을 구현하여 성능 분석중에 있으며 향후 이 시스템이 완전히 개발 된다면 국방 경계태세 강화 등 다른 여러 분야에서 유용하게 쓰일 것으로 기대된다.

Brain Computer Interface(BCI)분야는 뇌파를 이용하여 컴퓨터를 컨트롤 하는 기술로 최근 많은 연구가 이루어 지고 있다. 뇌파는 주변 상황과 개인, 상태에 따라 그 변화가 명확하기 때문에 BCI 분야는 앞으로 많은 응용 프로그램 개발에 충분한 자원이 될 수 있다. 기존의 BCI 연구는 뇌파를 입력 값으로 사용하여 컴퓨터를 컨트롤 하였다. 하지만 뇌파 값은 환경과 상황, 개인마다 다르기 때문에 특정 값으로 사용하기에 어려운 점이 있다. 본 논문에서는 이러한 뇌파의 특징을 이용하여 집중력을 향상시키는 개인용 게임시스템을 제안하고자 한다.

This study was to examine the effectiveness of neurofeedback training by observing the pre and post brainwave measurement results of about 16(Primary Student 6, middle school student10) student who have shown resistance stress and body stress, mental stress. The study was examined at S city M dong A hearing impairments student, from Mar. 2008 and to Feb. 2009. The methodology used in the study is the Coloring Analysis Program of the Brain Quotient Test. As the brain waves are adjusted by timeseries linear analysis, the brain function quotients can reflect the functional states of the brain. The training took place two times a week, for about 40 minutes per session. The result confirmed the differences of both resistance stress quotient and body stress, mental stress. The results of the analysis show that neurofeedback training plays positive role in changing the brain function. Therefore, the result of the study shows that there is possibility that Neuro Feedback technique might be positively affecting resistance stress of the hearing impairments student, relationship between neurofeedback training and stress among several categories.

Brain computer interface(BCI) technology has been continuously developed due to the continuous development of interface technology and the promotion of brain wave research. In this paper, we propose a driving habit management system by adopting BCI to transportation. The proposed system consists of the electroencephalogram(EEG) measuring unit, the EEG analysis unit, the memory section for storing the state information of drivers, the speed controller unit and the alarming section for generating warnings. Our proposed system can reduce the drowsy driving, improve the driving habits of users and help to prevent traffic accidents.

With the technological development, benefits of Virtual Reality (VR) has become a key of medium in communication research. In addition, explaining human minds with physiological data has become more popular since more accurate and detailed data can be expressed. However, reading brain signals in a virtual environment setting with psychophysiological measures (e.g. EEG and fNIRS) has remained a difficulty for researchers due to a technical constraint. Since a combination of cables for brain measures attached to a head cap obstruct wearing a Head-Mounted Display (HMD) over the cap, measuring brain activities with multiple channels on several areas of the brain is inappropriate in the VR setting. Therefore, we have developed a new brain measurement cap that includes probe connectors and brackets enabling a direct connection to the HMD. We highly expect this method would contribute to cognitive psychology research measuring brain signals with new technology.

Recently, the meditation is getting a major concern because of the trend of wellbeing. The various meditation methods are introduced, but, we need to take an appropriate method for himself or herself. Especially, the numbers of meditators who are using meditation music while they are meditating are increasing. Some people say it is helpful, but others don't. Therefore, I have studied the impact of the meditation music in this paper. I have compared between the meditation with the music and without the music by measuring the channels of left and right hemisphere of prefrontal lobe with 14-channel EEG device. For the result, I have found that there are great difference between two experiments.

User interface design environment has been known to be part of important elements in user experience and play, and its significance of functionalities are growing bigger each year. In present day, use of intuitive user interface design are on demand. Player can expect to get a new experience that they can not get from other exiting or similar form of games. For the better user experience, essential use of intuitive game play is necessary along with its perceptive user interface. This paper describes intuitive game environment design which will enhance user experience with use of brainwave signal for Brain Computer Interface.

Recently, systematic research on the brain has been conducted and BCI(Brain -Computer Interface) technology applying electroencephalogram has been actively researched. Especially, serious game technology using BCI device has been the subject of interest. This paper develops a "twosome collaboration dance game," which is a serious game that takes advantage of NeuroSky's SDK(System Development Kit) and helps developing the spirit of team work and sociality based on attention and meditation, unlike existing single player games. We expect that this game will help to visualize brain functions of people and to cure ADHD children and the elderly people with MCI(Mild Cognitive Disorder). It is also expected to play a role of social catalyst to the game culture of the adolescent.

In cloud, everything can be provided as a service wherein a large number of users submit their jobs and wait for their services. hus, scheduling plays major role for providing the resources efficiently to the submitted jobs. The brainwave of the proposed ork is to improve user satisfaction, to balance the load efficiently and to bolster the resource utilization. Hence, this paper roposes an Adaptive Multilevel Scheduling System (AMSS) which will process the jobs in a multileveled fashion. The first level ontains Preprocessing Jobs with Multi-Criteria (PJMC) which will preprocess the jobs to elevate the user satisfaction and to itigate the jobs violation. In the second level, a Deadline Based Dynamic Priority Scheduler (DBDPS) is proposed which will ynamically prioritize the jobs for evading starvation. At the third level, Contest Mapping Jobs with Virtual Machine (CMJVM) is roposed that will map the job to suitable Virtual Machine (VM). In the last level, VM Scheduler is introduced in the two-tier VM rchitecture that will efficiently schedule the jobs and increase the resource utilization. These contributions will mitigate job iolations, avoid starvation, increase throughput and maximize resource utilization. Experimental results show that the performance f AMSS is better than other algorithms.
