In this paper, we propose a new NLM(NMF-based LDA Mixture) algorithm for real-time face recognition system. This system greatly consists of the two parts: 1) face extraction part; 2) face recognition part. In the face extraction part we applied subtraction image, color filtering, eyes and mouth region detection, and normalization method, and then in the face recognition part we used NLM in extracted face candidate region images. The existing recognition system using only PCA(Principal Component Analysis) showed low recognition rates, and it was hard in the recognition system using only LDA(Linear Discriminants Analysis) to apply LDA directly when the training set is small. To overcome these shortcomings, we reduced dimension as the matrix that had non-negative value to be different from former eigenfaces and then applied LDA to the matrix in the proposed system. We have experimented using self-organized DAUFace database and ORL database offered by AT&T laboratory in Cambridge, U.K. to evaluated the performance of the proposed system. The experimental results showed that the proposed method outperformed PCA, LDA, ICA(Independent Component Analysis) and PCA-based LDA mixture method within the framework of recognition accuracy.

In this dissertation a novel speed control system that implements the fuzzy logic controller(FLC) is proposed. The proposed FLC used the speed error its rate of change, and the drive current as three fuzzy variables. The real command output current is chosen by the defuzzification of fuzzy output extracted from the fuzzy control rules. The flex and the torque of the induction motor are estimated using the dynamic model with an excellent dynamic response over a wide speed range and with the rotor flux field-oriented scheme of the decoupling characteristics The performance of this control system is substantiated by computer simulations.

SUMMARY Since the late 1960s when the discussion about software crisis - the problem of building large, reliable software system in a controlled and cost-effective way - was risen, many methodologies have been introduced to solve that problem, and software reuse can be regarded as one of these efforts. Software reuse is using existing software components during the construction of a new software system. The types of components that can be reused are not limited to source code but rather may include design specification, documentation, module-level implementation, a variety of knowledge from all the development phases, and so on. In spite of its promise, software reuse has failed to become standard pratice for software construction. In light of this failure, the computer science community has renewed its interest from the late 1980s. Most of the research has focused only on the technical aspect of software reuse since then, and little attention to managerial considerations. A successful adoption of new technology in an organization, however, cannot be achieved only with technology itself, but rather together with managerial aspects. Therefore, we tried to find a business considerations for strategic implementation of software reuse. To achieve this goal, we first study the concept, history, and the effects of strategic implementation of software reuse from the point of management strategu, motivation, and organization structure. Finally, the case of Motorola company was analyzed. We tried to propose managerial guidelines for strategic implementation of software reuse, and this will be helpful to make plans for that and to decrease the chance of trial and error during the adoption phases of new technology.

One essential contribution to a successful soccer game, which is still not always recognised as such, is the standard and quality of the lighting system. This is not only for TV transmissions, but also for the general practising of the sports. But, on too many occasions, sport activities and events have been allocated with insufficient or Inappropriate lighting system. inadequate lighting spoils not only the pleasure and the interests of active sportsmen, but also the comfort of the spectators in both the stadium and at home watching their TV. So this paper newly proposes the algorithm for searching of luminaire position which can be applied to the design stage.

The auditor's analytical review has recently been the focus of numerous articles and discussions, yeti little knowledge is available on the practice of analytical reviews. Analytical reviews first recived explicit recognition within the auditing standards in 1972 {SAP No.54(AICPA, 1972)}, Presently analytical review are considered substantive tests that can significantly affect the nature, timing, and extent of other procedures{SAS No.23}. In accrdance with this recognition, there exists an increasing awareness of the potential for analytical review to improve audit efficiency and effectiveness.

다수당에 의한 미국 하원 규칙위원회의 장악 : 민주당에 의한 1961년 규칙위원회 구성원 확대에 관한 연구

손병권 서울대학교 국제지역원 1998 국제지역연구 Vol.7 No.3

본 논문은 1961년도 제 87대 의회에서 다수당인 민주당에 의해 실행된 규칙위원회의 구성원 확대에 관한 연구이며, 규칙위원회의 확대가 제 87대 의회에서 발생한 이유를 설명하는 것을 논의의 핵심으로 삼는다. 1961년 하원 규칙위원회의 확대는 당시 다수당인 민주당이 연방정부의 적극적인 개입을 통해서 실업, 교육,최저임금 및 도시 개발 문제등 사회 문제를 해결해야 한다는 필요성과 밀접하게 관련되어 있었으며, 이러한 문제의 해결은 하원 규칙위원회의 개혁을 전제로 하였고, 그 개혁은 또한 보수적인 규칙원원회의 구성원을 부분적으로 변화시키는 갓을 필연적으로 요구하고 있었다. 본 논문은 규칙위원회의 장악을 통해서 다수당이 획득할 수 있는 정책적 이익이 증가함에 따라 다수당의 규칙위원회의 장악의 시도 가능성이 높아진다는 검증 가능한 주제하에서 1961년의 규칙위원회 구성원 확대 문제를 다루었다. 이러한 정당이익적 관점에서 규칙위원회의 장악을 설명하기 위해서 일차원적 공간이론(unidimensional spatial theory)이 방법론적인 측면에서 원용하였으며, 이 이론을 통해서 규칙위원회 장악 이후 다수당인 민주당의 정책적 이익이 비다수주의적(nonmajoritarian), 정당적 정책 결과에 의해 증가햐였음을 밝혔다. The purpost of this article is twofold. The first one is to explain the incidence of Rule Committee capturing (the enlargement of the Rules committee) in the 87th House in 1961 : the second is to provide a partisan context for the Rules Committee enlargement. The main argument of the article is as follows : the 1961 Rules committee enlrgement in the 87th House in 1961 was executed for the purpose of legislating the kennedy programs, which entailed entailed the expansion of the federal govemment and the increase in federal expenditure. In order to legislate liberal kennedy programs, it was necessary for the Democratic majority party to capture the Rules Committee. And the capturing took place in the 87th House when the Democratic party had a substantive incentive. In order to emphasize the partisan nature of the Rules Committee reform, I provide crucial background information on the deteriorating relationship between the Democratic majority party and the Republican minority party since the 1958 congressional election. In line with the revitalized inter-party conflict. I also show the way the increased power of the liveral wing within the Democratic party made Speaker Sam Raybum inevitably consider taking some measures to control the Rules Committee. After that, I develop a formal model to test the incidence of capturing and come to the conclusion that one major necessary condition for the majority party to capture the Rules Committee is that it should be able to increase its policy utility by capturing. In other words, only when the majority party has an incentive to cpature the Rules Committee in terms of policy benefit, does capturing take place. The outcome of the test based on the " Rosenthal and Poole data" of the 87th House proved the thesis.
