Love which is one of the emotional of mankind, has been studied in sociology and psychology as a matter of grate concern. In this paper we represent romantic behaviors in the love equation of Romeo and Juliet as time series and phase portraits in the case of with and without time delay. And we also analyze their difference.

Love which is one of the emotional of mankind, has been studied in sociology and psychology as a matter of grate concern. In this paper We represent romantic behaviors in the love equation of Romeo and Juliet as time series and phase portraits. Also we analyze the behavior's relation by using time series and phase portraits when external force applied as the third person between Romeo and Juliet.

Historical compliance with economics in a political interchange accepts the elements of multiculturalism to develop a new field in the research with China. New research seeks to point out the characteristics of the Baekje dress style in relation to studies on East Asian fashion that observe the role and place of Baekje apparel. This study reveals the formation background of Baekje dress culture. Examined are the cognitive world of Baekje dress culture. The study reveals the form of the three Baekje Kings and royal dress.

Mareel and Bitmead proved the presence of chaotic signal in random noise by applying dead beat control theory to adaptive mechanism. In this paper robust adaptive theory is proposed. With the property of chaotic signal that has order and law, the proposed theory can enhance the control Performance by applying the recursive algorithm that uses dynamic relation which have small correlation. The performance of proposed algorithm is demonstrated with the computer simulation of position control of electric motor. In this simulation, the adaptive low is adopted to control electric motor and the Presence of chaotic signal in feedback signal is proved by using several method such as time series, fourier spectrum phase portrait method.

Young-dang(影堂) is a ritual pavilion where figures of a dedicated person is enshrined. According to literature, establishment of Young-dang architecture is thought to have the affinity with Buddhist tradition in the beginning of its history. A tradition of enshrining figure could be found especially in Buddhism. Until the mid Joseon dynasty, enshrining figure made of wood, clay and bronze was quite often at Young-dang. In Confucian ritual tradition, a pavilion where enshrining ancestor's sprit tablet called Sadang(祠堂) or Myo(廟). In regarding portrait is a sort of figure, it has to be concerned with Buddhist ritual tradition. For this reaseon, Young-dang started to be distinguished from older aspect of existence in mid Joseon dynasty when the study of Confucian courtesy widely spread. It show the transformation process of Young-dang architecture from Buddhist tradition to Confucian tradition in J oseon dynasty.

This paper focuses on historical instances of iconoclasm after the Reformation to reveal how iconoclasm had greatly contributed to the formation of the Protestant mindset in the early modern times. During the English civil war, when iconoclastic campaigns and movements were in full tide, the paper argues that the notions of novelty and progress were more positively accepted among radical religious groups. To put it in another way, the paper suggests a different way of looking the formation of Protestant habitus by giving accounts of how iconoclastic impulses spurred diverse religious groups during the civil war to break the mold of conservative thinking and to revolutionize the print culture hitherto based on patronage and served as a buttress for status-quo. From this analysis, then, we are ledto the different portrait of the protestant in the seventeenth century, whose mindset was not quite as solitary and guilt ridden as Max Weber would have us believe.

Noise is a fundamental factor to increased validity and regularity of spike propagation and neuronal firing in the nervous system. In this paper, we examine the stochastic version of the Izhikevich-FitzHugh neuron dynamical model. This approach is based on techniques presented by Luo and Guo, which provide a general framework for the bifurcation and stability analysis of two dimensional stochastic dynamical system as an Itô averaging diffusion system. By using largest lyapunov exponent, local and global stability of the stochastic system at the equilibrium point are investigated. We focus on the two kinds of stochastic bifurcations: the P-bifurcation and the D-bifurcations. By use of polar coordinate, Taylor expansion and stochastic averaging method, it is shown that there exists choices of diffusion and drift parameters such that these bifurcations occurs. Finally, numerical simulations in various viewpoints, including phase portrait, evolution in time and probability density, are presented to show the effects of the diffusion and drift coefficients that illustrate our theoretical results.

본 연구는 휴머노이드 로봇 중에서 사람과 같은 방법으로 초상화를 그리는 로봇 암의 이동 궤적 최적화에 대해 기술한다. 이전에도 이러한 사람의 얼굴을 초상화로 그리는 로봇이 존재하였지만 대부분 인간과 유사한 움직임을 보이지 못하고 딱딱하고 단조로운 움직임을 보였다. 이런 단점을 보완하기 위해 가장 짧은 궤적을 찾는 알고리즘을 사용하여 보다 유연한 움직임을 구현하고, 초상화를 그리는 일련의 과정 중에서 입력된 영상을 가공하여 인간과 같이 그릴 수 있는 좌표를 효과적으로 정렬하고, 추출된 좌표를 바탕으로 로봇 암의 가장 빠르고 효율적인 이동궤적을 구한다.

최근 다양한 영상 매체가 활발히 발전함에 따라 1인 방송자가 늘어나는 추세이다. 방송 중 타인의 동의 없이 얼굴이 노출되는 경우 초상권 침해가 발생한다. 이러한 경우를 방지하고자 본 논문에서는 딥러닝 기반 실시간 객체 인식 기술을 통하여 방송자의 얼굴을 인식하고 방송자의 얼굴이 아닌 일반인으로 인식되는 얼굴은 실시간 모자이크 처리를 통하여 일반인의 초상권 보호를 목적으로 한다.

본 연구는 초상권을 보호할 수 있는 실시간 영상 모자이크 서비스이다. 실시간 모자이크 서비스에서는 모자이크 처리를 제외하기 위한 이용자 얼굴 등록 기능을 갖고 있다. 이렇게 등록된 얼굴정보는 실시간 영상 스티리밍 서비스에서 모자이크가 되지 않도록 한다. 즉, 모자이크를 원하지 않는 정보를 미리 시스템에 등록하여 실시간 서비스에 어떠한 부분을 모자이크에서 제외 할 것인지 세팅하여 실시간 스트리밍 서비스를 제공한다. 기존 기술과의 차이점은 사람의 얼굴뿐만 아니라 방송에 나오면 안 되는 흉기나 담배 등을 모자이크 처리해 줄 수 있는 기능을 제공하고, 실시간으로 모자이크된 영상 스트리밍 서비스를 제공할 수 있는 장점을 갖는다.
