        스트링의 최대 서픽스를 계산하는 효율적인 외부 메모리 알고리즘

        김성권,김수철,조정식 한국정보처리학회 2008 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.15 No.4

        We study the problem of finding the maximum suffix of a string on the external memory model of computation with one disk. In this model, we are primarily interested in designing algorithms that reduce the number of I/Os between the disk and the internal memory. A string of length N has N suffixes and among these, the lexicographically largest one is called the maximum suffix of the string. Finding the maximum suffix of a string plays a crucial role in solving some string problems. In this paper, we present an external memory algorithm for computing the maximum suffix of a string of length N . The algorithm uses four blocks in the internal memory and performs at most 4 disk I/Os, where L is the size of a block. 외부 메모리 계산 모델에서 스트링의 최대서픽스를 찾는 문제를 고려한다. 외부메모리 모델에서는 디스크와 내부메모리 사이의 디스크 입출력 횟수를 줄이는 알고리즘을 설계하는 것이 중요 사항이다. 길이가 N인 스트링은 N개의 서픽스를 가지는데, 이중에서 사전 순서에 따라 가장 큰 것을 최대 서픽스라 부른다. 최대서픽스를 구하는 것은 여러 스트링 문제를 해결하는 데 중요한 역할을 한다. 본 논문에서는 길이가 N인 스트링의 최대 서픽스를 구하는 외부메모리 알고리즘을 제시한다. 이 알고리즘은 네 개의 내부 메모리 블록을 사용하고 최대 4(N/L)번의 디스크 입출력을 한다. 여기서 L은 블록의 크기이다.

      • 消費者行動 모델의 評價

        金聖權 又石大學校 1983 論文集 Vol.5 No.-

        One of the most challenging task facing consumer behavior researchers is that of integrating various research findings. It is all too easy to speak only of consumer's attitudes or their social roles. Yet, there is no single phenomenon, such as altitudes of roles or learning, which fully explains and predicts what consumers really do. The difficult task is to understand all of the separate components of consumer behavior and how they fit together. It may come as a surprise to discover that several comprehensive models of consumer behavior have been proposed to perform this difficult task. These models (The Forward-Sheth model, The Sheth Model of Industrial Buyer Begavior, The Engel, Kollat, Blackwell Model, The Kerby Model, The Andreasen Model, The Nicosia Model) are explained, compared and then evaluated in this study. The criteria for evaluating models are : Capable of prediction as well as explanation General High in heuristic power High in unifying power Internally consistent Original Plausible(Have face validity) Simple Supported by facts Testable, Verifiable There is not, nor is it possible that there could be, a model of consumer behavior which could satisfy all of these criteria. Thus, it is not necessarily a justifiable criticism to say that a particular model does not meet one of the criteria. To some degree, the reader must supply the missing parts or processes that tie together or complete the representation. Any criticism of specific models must be accepted in this light.

      • 敎育課程 構造化의 發達的 基調(1)

        金聖權 대구교육대학교 1969 論文集 Vol.5 No.-

        In the latter half of 1950s, the curriculum reformation movement took place, and it has been imprinted on the structuralization theory. It has attempted the modernization of the contents and method of education, and also intended to reform the old traditional school educatation fundamentally as well as qualitatively. In America the attempt for the structuralization of PSSC, BSCS, CBA, and UICSM, etc. - which have been with the development of the modern scientific technique for the background, and centered in the fields of science and mathematics - has brought good result, as it were, to the ardent discussion about the principle of the disciplinary approach. Thus nowadays the structuralization movement comes to be founded on the discipline centered curriculum. The previous studies by the internal of foreign scholars have greatly helped me for this study. For the purpose of finding out the point of reformation with regard to the curriculum structuralization in our country, and also by means of the analytical method of bibliography. 1. I largely divided the contents of this study into two parts: (1) The problem for the curriculum structuralization in a narrow(general) sense. (2) The problem for the curriculum structuralization in a wide sense 2. The aims of this study are divided into three parts. They are as follows: (1) To investigate the background of the educational history of the structuralization movement, and to define the foundation (2) To explain the basic conception of the stucturalization, and to show the way so as to solve the question of the structuralization (3) To awaken and show new ways and consciousness, concerning the teaching method, in clarifying the connection between the learning theory and the structuralization. 3. As the result of this study I want to give the following three kinds of suggestions. (1) It is necessary for us to clarify the structuralization conception more highly, for the structuralization has the various differences according to the study course and the classifying datum point. So we need the research in this field. (2) Instead of giving up the structuralization of department system centered only in the science and mathematics course, we have to solve the structuralization problem throughout all the lessons. (3) In the curriculum structuralization problem, five have to investigate the best teaching methods that are fit for the conditions such as the contents of knowledge, the aim of education, the developmental processes of learners, and tile individual differences, etc. I lastly come to the conclusion that not only the curriculum structuralization problem is based on the educational philosophy in the educational object, contents and method, but also its indispensable conditions are the organic and concentrative research, the practice, and the evaluation. It seems that the generalization and continuity of the researching result are secured for the first time from such a basic point of view as his study.

      • 고속무선LAN설비를 위한 저소비전력형 OFDM LSI구현에 관한 연구

        김성권 木浦海洋大學校 2005 論文集 Vol.13 No.-

        OFDM(Orthogonal Frequency Division Multiplexing)변조방식은 데이터를 다수의 반송파를 이용해서 주파수상에서 분산해서 전송하는 디지털변조방식의 일종으로, 멀티패스 간섭에 강한 이점 등으로 인해 디지털음성방송이나 지상파 디지털TV방송 등에 적용되고 있으며, 1997년부터는 5GHz대역의 구내용 초고속무선LAN설비로서 IEEE 802.11 TG(Task gruoup)a에서의 규격작업이 이뤄짐에 따라, 관련된 연구들이 활발하게 진행되어지고 있다. OFDM방식의 초고속무선LAN설비를 구현하기 위한 송수신부의 핵심소자로서는 IFFT 및 FFT모듈이 있다. 본 논문은 IFFT 및 FFT 모듈을 행렬 원소의 라운딩기법을 기반으로한 전류모드회로를 이용해서 설계 및 구현함으로써 저소비전력화와 고속처리동작이 가능하도록 하였다. 또한 제안한 IFFT 및 FFT모듈을 IEEE 802.11a규격에 근거한 송수신부 모뎀에 적용한 경우에 대한 BER특성을 모의실험을 통해 확인함으로써, 제안한 IFFT 및 FFT모듈을 이용한 송수신 시스템 설비가 AWGN채널 환경에서 유용하게 동작함을 입증하였다. OFDM(Orthogonal Frequency Division Multiplexing)is a one of most promising digital modulation techniques adapted for Digital audio broadcasting or Digital TV since it is very robust against multipath fading channels. From 1997, since the OFDM technique was considered as the physical layer standard for the high data rate wireless LAN systems in the 5GHz band, related studies have been studied actively. The key elements to implement high data rate wireless LAN system using OFDM technique are IFFT and FFT modules. In this paper, new IFFT and FFT module are designed and implemented using current cut circuit based on the matrix-rounding process for the low-power consumptive operation and high-speed data processing. In addition to, we certify the available operation of the rounded IFFT/FFT module in the AWGN channel by using the BER performance simulation of IEEE 802.11TGa based OFDM modem with rounded IFFT/FFT module.

      • 굵은 골재 종류에 따른 포장 콘크리트의 피로특성

        김성권,김동호,윤병성,이봉학 江原大學校 産業技術硏究所 2004 産業技術硏究 Vol.24 No.A

        It is the purpose of this study to identify comprehensive fatigue characteristics of pavement concretes considering coarse aggregate types. The types of coarse aggregates considered are limestone, sandstone and granite, which are the most representative stones in Korea. The static strength tests were carried out to check the compressive strength, flexural strength at 7 and 28 days, and split tension strength at 56 day in order to minimize the various effect of strength during the test. The results are follows. The comprehensive fatigue models of pavement concretes were developed considering coarse aggregate types. The developed model showed a good relationship between aggregate types. The fatigue models with coarse aggregate types were shown, respectively. The combined fatigue models was also shown.
