본 연구는 지역별 우수수업 동영상에서 나타나는 수학적 의사소통이 어떻게 이루어지고 있는지를 분석하여 양질의 수업을 찾아 교사의 수업 관행에 도움을 주고자한 것이다. 교사와 교실 전체 간에 이루어지는 담화를 중심으로 수업을 분석하기 위해 다음과 같은 연구문제를 설정하였다. 첫째, 지역별 우수수업 동영상의 수학적 의사소통 수업유형은 무엇인가? 둘째, 지역별 우수수업은 의사소통이 어떻게 이루어지고 있는가? 셋째, 담화중심 수업의 수학적 의사소통 수준은 어떠한가? 공개된 24개의 수업을 수업 유형에 따라 분류한 결과 초등학교 수학 수업의 특성상 조작 중심수업 유형이 가장 많은 것으로 나타나 다른 유형의 수업도 좀 더 이루어질 필요가 있음을 알 수 있었다. 그리고 교수 학습 지도안에서 수학적 의사소통 능력을 고려한 수업은 5개이며 이 중 1개 수업만이 수학적 의사소통 능력을 인지적 영역에 포함시키고 있어, 수학적 의사소통 능력에 대해 교사가 정확히 알 필요가 있었다. 또한, 학생 간 질문하기를 수업에 반영할 필요가 있었다.

An efficient synthesis method of cellular architecture FPgA is proposed in this paper. To generate a logical representation called complex term which is to be directly mapped onto the cellular architecture FPGA, and SO or ESOP minimization tool was used in previous methods. Instead, we use a logic function transformed into BDD (binary decision diagram) in the actual generation of the complex temrs. In this process it estimates the cost(i.e. the number of complex terms) for three branches, 0-branch and 1-branches. This process is continued over the whole BDD to do such computation, and we observed that the number of complex terms has been reduced compared to the previous results.

In the framework of linear representation which allows for no internal structure within features, there is no way to represent nonlinear phonological phenomena such as complex segments. This paper shows how we carl solve some problems of the linear feature theory in relation to the hierarchical feature theory. The purpose of this paper is to explain lateral assimilation under hierarchical feature representation. Although arguments for the position of classes of distinctive features have been made the position of (lateral) remains the issue of debate. Sagey(1988) argues that the feature [lateral] is structurally dependent on the root node. In contrast Rice & Avery (1991) put the feature (lated) under the spontaneous voicing. I have discussed previous studies of feature hierarchy and I propose a revised model of feature representation. Within this model I have shown how well feature geometry describes lateralization as feature spreading.

To accomplish various and complex tasks by intelligent robots, improvement is needed not only in mechanical system architecture but also in control system architecture. Hybrid control architecture has been suggested as a mutually complementing architecture of the weak points of a deliberative and a reactive control. This paper addresses a control architecture of robots, and a behavior representation methodology. The suggested control architecture consists of three layers of deliberative, sequencing, and reactive as hybrid control architecture. Multi-layer behavior model is employed to represent desired tasks. 3D simulation will be conducted to verify the applicability of suggested control architecture and behavior representation method.

Vector fields in three-space admit bundles of internal variables such as a Heisenberg algebra bundle. Information transmission along field lines of vector fields is described by a wave linked to the Schrodinger representation in the realm of time-frequency analysis. The preservation of local information causes geometric optics and a quantization scheme. A natural circle bundle models quantum information visualized by holographic methods. Features of this setting are applied to magnetic resonance imaging.

This study investigates great potential of architectural representation drawings for architects as well as designers to realize their design concept into visual forms. In 1988, an exhibition called "Deconstruction in Architecture" at Modern Art Museum, New York, was an important turning point in design representation. The study examines design drawings of architects of deconstructivism to analyze new attitudes toward building forms and programs in contemporary architecture. The study found in the drawings that initially, collages in many different types are often utilized to express simultaneous time and space. Secondly, section drawings become more important to explain ambiguous and complex floor system than before. Thirdly, cinematic montages are utilized to express indeterminate or loose programs. Fourthly, diagrams are utilized to visualize initial conditions and clues of design solution. The study concludes that design drawings are not only representation media admitting of changes and progress but also tools of design creation. creation.

An operator T on a complex Hilbert space H is called skew symmetric if T can be represented as a skew symmetric matrix relative to some orthonormal basis for H. In this paper, we study skew symmetric operators with eigenvalues. First, we provide an upper-triangular operator matrix representation for skew symmetric operators with nonzero eigenvalues. On the other hand, we give a description of certain skew symmetric triangular operators, which is based on the geometric relationship between eigenvectors.

The level-m scaled circulant factor matrix over the complex number field is introduced. Its diagonalization and spectral decomposition and representation are discussed. An explicit formula for the entries of the inverse of a level-m scaled circulant factor matrix is presented. Finally, an algorithm for finding the inverse of such matrices over the quaternion division algebra is given.

In the paper, we investigate the representation of the numerical range W(An) for the 2 × 2 complex matrix A, in terms of the numerical range W(A) of the matrix A, and the elements of A or the eigenvalue of A.

In this paper, a new seven-parameter Mittag-Leffler function of a single complex variable is proposed as a generalization of the standard Mittag-Leffler function, certain generalizations of Mittag-Leffler function, hypergeometric function and confluent hypergeometric function. Certain essential analytic properties are mainly discussed, such as radius of convergence, order, type, differentiation, Mellin-Barnes integral representation and Euler transform in the complex plane. Its relation to Fox-Wright function and H-function is also developed.
