  • Recently, a brain imaging system with microwave devices has been proposed. The brain imaging system requires a small antenna which has ultra wide band(UWB) operating frequency bandwidth(0.5~2 GHz) and non-varying boresight of antenna over the frequency band. This paper proposes asymmetric corrugations on a tapered slot antenna (TSA) so that the size of the TSA is reduced by 14 % while 10 dB return loss bandwidth is satisfied over the operating frequency band from 0.5 GHz to 2 GHz. A miniaturized TSA with symmetric corrugations shows tilted boresight whilst frequency is getting lower; however, the proposed TSA with asymmetric corrugations maintains direction of boresight for different frequencies. This enhancements make an asymmetric corrugated TSA meet the requirement of the brain imaing system.

  • 목적 : 전통적으로 태충($LR_3$)과 양릉천($GB_{34}$)은 운동기능과 관련된 질환에 사용되어 왔다. 우리는 두뇌에 신경독을 주입하여 파킨슨병 쥐모델을 제작하였고, 쥐는 운동기능이 손상되고 도파민성 신경세포가 선택적으로 소멸하였다. 병증 모델 쥐에게 태충과 양릉천에 자침한 결과 운동기능이 개선되고 신경세포보호효과가 나타남을 관찰한 바 있다. 이에 실제로 태충과 양릉천에 자침하여 운동기능과 관련된 추체외로 영역에서 신경의 활성화가 나타나는지를 fMRI를 통하여 관찰하였다. 방법 : 자침은 수기침을 선택하였으며, 혈위는 (1) 태충, (2) 양릉천, (3) 태충+양릉천의 세군데를 설정하였고, 자침에 대한 대조자극으로 피부자극을 채택하였다. fMRI 스캐너는 3T를 사용하였고 뇌신경 활성화의 신호는 BOLD(blood-oxygen-level dependant)를 관찰하였다. 두뇌에서 관찰부위는 중뇌를 중심으로 추체외로로 한정하였다. 결과 : 태충에 자침하였을 때 두뇌의 substantia nigra, subthalamic nucleus, red nucleus, pons 등이 활성화 되었다. 양릉천에 자침하였을 때 substantia nigra, subthalamic nucleus, caudate nucleus, thalamus가 활성화 되었다. 태충과 양릉천에 동시에 자침하였을 때는 substantia nigra, subthalamic nucleus, red nucleus, globus pallidus가 활성화되었다. 대조자극에 의해서는 위의 영역들이 활성화되지 않았다. 결론 : 태충, 양릉천, 태충+양릉천 자극은 대뇌에서 추체외로 영역을 활성화시키며 특히 substantia nigra의 활성화는 파킨슨병과 같은 질환의 조절가능성을 시사한다.

  • The hamonious development of human brain has been an indigenous objective of each age. A variety of training programs related to the purpose have turned up at an educational market and a commercial market, as well. I'd like to indicate, however, that these training methods are somewhat prejudiced and have some elements, inherently, which are against the development of human brain for one's whole personality. Therefore, the most desirable brain training program is to induce it to respond to various stimuli, to educate for itself and to generate continuously, to create and strengthen an innumerous synapse among brain cells, so as to form a nero-network. In this study, I have used a brain training program with multimedia which have been produced for a specific purpose. With this method, by measuring directly the effectiveness of human brain development, I have analysed more objectively and more quantitatively.

  • Many researchers are studying about human Brain-Computer Interface(BCI) that it based on electroencephalogram(EEG) signals of multichannel. The researches of EEG signals are used for detection of a seizure or a epilepsy and as a lie detector. The researches about an interface between Brain and Computer have been studied robots control and game of using human brain as engineering recently. Especially, a field of brain studies used EEG signals is put emphasis on EEG artifacts elimination for correct signals. In this paper, we measure EEG signals as human emotions and divide it into five frequence parts. They are calculated related the percentage of selecting range to total range. the calculating values are compared standard values by Bayesian Network. lastly, we show the human face avatar as human Emotion.

  • Researchers in the field of psychology used Electroencephalographic (EEG) to record activities of human brain lot many years. As technology develope, neural basis of functional areas of emotion processing is revealed gradually. So we measure fundamental areas of human brain that controls emotion of human by using EEG. Hands gestures such as shaking and head gesture such as nodding are often used as human body languages for communication with each other, and their recognition is important that it is a useful communication medium between human and computers. Research methods about gesture recognition are used of computer vision. Many researchers study emotion recognition method which uses one of physiological signals and gestures in the existing research. In this paper, we use together physiological signals and gestures for emotion recognition of human. And we select the driver emotion as a specific target. The experimental result shows that using of both physiological signals and gestures gets high recognition rates better than using physiological signals or gestures. Both physiological signals and gestures use Interactive Feature Selection(IFS) for the feature selection whose method is based on a reinforcement learning.

A Study on Reading Guidance for Creativity Enhancement by Using Fantasy Literature (팬터지를 이용한 독서지도에 관한 연구: 학생들의 창의력 제고를 중심으로)

  • The author describes the reasons why fantasy literature is more useful for reading guidance than realistic fiction. The activities of the human brain are in accordance with the activities of creating fantastic stories. She explains that the characteristics of creativity. according to the findings of psychologists and neuroscientists, are inherent in the activities of the human brain which is integrating information. These properties of information integrating are strongly immanent in fantasy literature. Fantasy literature provides the brains of readers with opportunities to integrate information because of its heterogeneity, for fantasy literature includes both realistic and unrealistic characters and settings comparable to those of realistic fiction. Also fantasy literature appeals to the curiosity and interest of young people, so students easily pay attention to it. Therefore, the author recommends that teacher-librarians use fantasy literature for reading guidance for students. In order to achieve successful reading guidance at school libraries, the author recommends the following. 1) A school library should have teacher-librarians who are well grounded in literature. 2) School authorities should elevate the teacher-librarian’s status to the same level as that of other teachers and create conditions such that teacher-librarians can best carry out their responsibilities. 4) It is necessary that a variety of lesson plans be developed for use by teacher-librarians.

  • Now a days, according that the occurrence of industrial disaster is on the increase, the necessity of protective goods is increasing. Specially estimate of safety helmet for protect of head is very important. On this, in this paper, amplification ratio and natural frequencies of fire safety helmet and general safety helmet are estimated by falling impect test and frequency analysis. Also. trend of damping is estimated by using these test results. And we know that the fire safety helmet is more safe than general safety helmet for protect of head.
