In this brief, a generation method of chaotic binary sequence is presented, and it has been also shown that chaotic binary sequence generator using the piecewise linear one-dimensional chaotic map(sawtooth map) with the inputs of irrational numbers generates more longer sequence than random binary sequence obtained from the mLFSR(maximum-length Linear Feedback Shift Register). The sawtooth map of 8-bit finite precision representation used in this paper is implemented with the digital device, 256×8 ROM(Read Only Memory).

An adaptive fuzzy sliding-mode control system, which combines the merits of sliding-mode control, the fuzzy inference mechanism and the adaptive algorithm, is proposed. A fuzzy sliding-mode controller is investigated in which a simple fuzzy inference mechamism is used to estimate the upper bound of uncertainties. The fuzzy inference mechanism with centre adaptation of membership functions is investigated to estimate the optimal bound of uncertainties.

본 논문에서는 1차원 혼돈맵들 중의 하나인 톱니맵을 16비트의 유한정밀도로 이산화시켜 설계하였고, 이 이산화된 톱니맵을 사용한 혼돈 2진 순서 발생기의 회로도도 제시하였다. 설계된 혼돈맵의 실제 구현은 이산화된 진리표로부터 얻어진 출력변수의 간략화된 부울함수에 따른 입력선과 출력선들의 정확한 연결에 의해 실현하였다. 최대길이를 발생시키는 선형궤환이동레지스터(mLFSR)에 의해 발생되는 난수성 2진 출력 순서들을 이산화된 톱니맵의 입력순서로 사용함으로써 결과적으로 최소 16배 더 긴 주기를 갖는 혼돈 2진 순서들을 발생시켰다. The discretized saw-tooth map with the 16-bit finite precision which is one of the 1- dimensional chaotic maps is designed, and the circuit of chaotic binary sequence generator using the discretized saw-tooth map is presented also in this brief. The real implementation of designed chaotic map is accomplished by connecting the input and output lines exactly according to the simplified Boolean functions of output variables obtained from truth table which is discretized. The random binary output sequences generated by mLFSR generator were used for the inputs of descretized saw-tooth map, and, by the descretized map, chaotic binary sequence which has more long period of 16 times minimally is generated as a results.
한국의 문화 : 경성제국대학 안의 "동양사학" - 학문제도,문화사적 측면에서 -

경성제국대학 출신의 조선인 동양사학 전공자의 의식 속에 동양사학은 "국사학"이라는 권력과 잠재적 "국사학"=조선사학이라는 상상 사이의 중간지점에 있었다. 그들이 식민지 학문의 중추 역할을 맡았던 경성제대 출신이었기 때문에, 그런 학문의 권력 문제와 관련한 고민을 더욱 심각하게 받아들였는지 모른다. 그들은 "동양사학" 출신자라는 학문적 동질감을 느끼지 못했기 때문에, 다른 학과와 달리 자신들만의 학술공간을 만들지도 못했다. 그와 같은 동양사학 전공자로서의 정체성은 그들의 독립 이후 활동과 지위에서도 잘 나타난다. 그들은 동양사학자의 지위에서뿐만 아니라, 대한민국 건국과 함께 대학과 문부 행정에서 오히려 ``국사학=한국사학`` 건설에 깊이 관여하게 된다. 1970년대에 들어서는 동양사연구자들 사이에서 동양사를 "조선 및 인접 지역을 대상으로 했던 이른바 조선학의 연구전통" 위에 "국사의 외연이나 관계사의 일환"으로 여기는 태도에서 벗어나야 한다고 비판하는 결과에 이른다. 그런 자기반성의 중심에는 이 대학의 출신자들이 있었다. 그들은 경성제대 사학과의 전공편성과 관련한 정치성의 자장으로부터 결코 자유로울 수 없는 존재였다. 따라서 그들의 존재는 한국의 동양사학 성립 과정에서 상징적이라고 할 것이다. When founded, Kyungsung(Keizo) Imperial University set it a goal to define the distinctive orientalism of Joseon based on cultural relationships with Japan and China. This is explained well by how Historical Studies department was organized. There were three majors including National History(that is Japanese History), Joseon History and Oriental History in that department. This was framed through modeling three major system in Imperial University in Japan while Joseon History major was included with World History left out. This disciplinary organization reflects how they tried to make this university as the supreme one in ``Japan empire`` as well as the center of ``oriental cultural studies``. Among three majors, Oriental History was considered as the most important one. It is notable that the consciousness of Korean students majoring in Oriental History was posited in a conflicting intermediate terrain between ``Japan History`` as power and ``Korean History`` as potential. They couldn`t help but doubt that their education and work were related to imperial power as the Kyungsung university played an important role in colonial studies. Obviously, the Korean students didn`t identified themselves with ``Oriental History`` in the university so that they couldn`t harbour their ambition of enlarging their work. Their unique identities as Oriental History scholars had a particular effect on the position that they occupied after the liberation of Joseon. They had instrumental in setting up National History(Korean History) as a new discipline under the establishment of the Republic of Korea. Since then, they continued to play important roles in that field. However, during 1970s the disciplinary scheme ran into the criticism from many researchers on the ground that it was narrowing Oriental History as a field by confining it to only "Korean History and other related countries` histories with it" and it came from colonial educational system, especially in Kyungsung Imperial University. Several researchers in favour of this criticism were in fact graduates of this university. And they were even right in the center of this criticism. In sum, they couldn`t stay away from the politics related with the disciplinary system coined in that university. Their positions stands as symbolic ones on the process of reestablishing Oriental History as a disciplinary in Korea.
