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.

Reliable wireless transmission of data generated by the flight critical subsystems or mission equipments of the unmanned aerial system is critical for mission success. As the UAS system becomes more sophisticated, its dependency on a reliable high rate radio communication system also increases. This requirement is applied not only during the operation phase but also in the early development test phase. This paper introduces a practical cost-effective communication system for a UAS. The downlink module combines analog NTSC video signal with onboard data, and send them using 2.4 GHz carrier wave. The uplink system has less a severe requirement on the bandwidth, and thus uses 430 MHz signal. This paper also presents a sample packet structure which can be adopted for many UAS of similar class.

Conventional Augmented Reality has used data gloves or markers for smooth interaction between objects and background. This causes inconvenience of use and lower immersion. To build up immersion in Augmented Reality, additional input devices must be removed. This paper proposes a method to create virtual space coordinates for interaction without wearing additional input devices so as to improve immersion in Augmented Reality. The acquired image was projected to a two-dimensional space and vanishing lines were extracted to calculate the virtual space coordinates. Then the sizes of the inserted objects were varied in accordance with the size of the virtual coordinates area based on the image projected onto the two-dimensional coordinates. This resulted in improved immersion. This method can increase the efficiency of object creation by excluding the use of a 3D modeler for creation of three-dimensional objects.

탄소나노튜브(CNT)를 이용한 초소형 X선 튜브는 근접 암치료, 비파괴 X선 영상 장치, 휴대용 X선 분광계 등에서 X선 발생소스로 많이 연구되고 있다. 2극형 CNT 에미터의 경우 구조가 단순하여 초소형 X선 튜브에 쉽게 장착할 수 있지만 아노드의 전압과 전류가 연동되기 때문에 튜브의 조작성이 제한적이다. 3극형은 상대적으로 복잡한 구조이고, CNT에서 방출된 전자가 게이트 전극으로 흐르는 누설 전류 그리고 절연체와 충돌하여 차징을 발생시킬 수 있기 때문에 직경이 좁은 초소형 X선 튜브에 구현하기가 쉽지 않다. 하지만 초소형 X선 튜브를 다양한 X선 장치에 응용하기 위해서는 아노드 전압과 전류의 독립된 조작이 가능한 3극형 CNT 에미터가 반드시 구현되어야 한다. 본 발표에서는 전자빔의 아노드 집속을 강화하고 절연체에서의 차징을 줄이는 포커싱 기능의 게이트(FFG) 구조를 제안하였고. 이를 적용하여 초소형 X선 튜브들을 제작하고, 분석하였다. FFG 구조가 성공적으로 적용된 초소형 X선 튜브는 게이트 누설 전류 없이 뛰어난 전류 및 X선 방출 특성을 보였다. 이와는 달리, 몇몇 초소형 X선 튜브들에서는 게이트 누설 전류가 나타났고, 아노드 전압에 의한 게이트 전압 상승이 발생하여 불안정한 구동 특성을 보였다. 초소형 X선 튜브를 밀봉하지 않고 진공 챔버에서 실험한 결과, 유도된 게이트 전압은 상당한 시간이 흐르거나 진공챔버에 공기를 주입하고 다시 진공상태로 만들면 유도전압이 제거되는 것을 볼 수 있었다. 결론적으로 CNT에서 방출된 전자빔이 정상궤도를 벗어나 게이트 누설전류와 차징에 의한 게이트 유도전압을 발생시키면 초소형 X선 튜브가 불안정한 구동을 하고, 결국 튜브의 심각한 결함으로 나타나게 된다. 즉, 게이트 누설 전류와 유도된 게이트 전압은 3극형 CNT 에미터가 장착된 초소형 X선 튜브의 디자인과 제작에 있어서 성공 기준이 될 수 있다.

A number of tangible cultural properties have been left to suffering damage without any scientific conservation or maintenance. We conducted nondestructive geophysical explorations around the Western pagoda of the Iksan Mireuksa Temple for the purpose of preparing the counterplan of its conservation and maintenance and of utilizing the geophysical information for the design of repair. Geophysical image of the shallow subsurface around the construct resulting from electric resistivity, seismic refraction, and GPR methods carried out along 6 lines in the site was used to investigate the relationship between the foundation characteristics and the structural safety. Tilting of the pagoda southwest towards seems to result from the low resistivity zones found in the southwestern part. The GPR and seismic surveys revealed a boundary at depth of 3.3～3.5m dividing into two layers, compacted overlaid soil and the original ground. The boundary appears to dip southwest. The artificial layer as a foundation does not covers as much as the bottom area of the pagoda. This top soil dipping southwest seems to result in tilting of foundation southwestward towards. Our geophysical result suggests ground reinforcement in the western part of the survey area for the conservation of the construct.

The study aims to present a solution to the problem of police physical fitness tests as police officers, who tried to subdue the drunk in a video clip titled "Darim-dong female police officer Assault" in May in Seoul, showed a rather lethargic figure, such as being pushed out of a physical fight with the suspect. The police physical fitness test is subject to criticism as it consists of items that are difficult to apply in real life despite having to be linked to job performance. The problem is that the physical fitness test events are not realistic, the physical fitness test standards are set too low, and their credibility is not reliable due to the imbalance of standards between men and women and the vision culture of physical fitness testing methods. First of all, we hope that the Republic of Korea will become a world-class security powerhouse by upgrading its physical fitness standards and establishing a scientific fitness test system for preventing injuries and effectively measuring physical strength.
