By analyzing one-parameter families of totally interpolating multiwavelet systems of minimal total length with low approximation orders, whose explicit formulas were obtained with the aid of well-known relations of filters, we demonstrate the infinitude of such systems.

The purpose of this study is to help the efficient and practical teaching and learning of a mathematic subject in schools by comparing and analyzing the sixth and seventh curriculum of mathematics on the basis of the demand that the current curriculum should be improved, made, and adapted newly. This paper 1. studies the meaning of the curriculum and the theory of the curriculum of mathematics 2. looks into the history of the curriculum of mathematics from the first to the sixth. 3. compares an outline of the sixth and seventh curriculum. As a result, it exhibits the great difference in giving students choices for subjects and nullifying the meaning of the subject distinction, which means a new system with consistency based on the concept of a grade system instead of the present school system. 4. summarizes the result of comparing and analyzing the sixth and seventh curriculum which will be practiced from the year 2002 5. The beginning of the seventh curriculum in high schools will be from the year 2002 and the ministry of education is expected to take proper actions for its successful settlement, yet at this point this study gives some suggestions for its smooth and normal operation.

This study is aimed at finding some drawbacks of current elementary mathematics textbooks and to give suggestions for ongoing new textbooks according to 2009 revised curriculums, by comparing and analyzing Korean textbooks and chinese textbooks of People's Education Press. The areas are confined to number concepts, addition and subtraction for comparative analyzing. The results are followings: Korea textbooks have more verbal expressions, designated instructive activities for students to do, similar algorithm applied for enlarging mathematical concepts, bigger number concepts and number usage of operations, and monotonous number sense activities. Therefore Korean textbooks, compared to China's, is more weaker in areas such as encouraging student's interest, in challenging mathematics, and in forming fundamental mathematical concept.

A physical variable is customarily thought of as a function. Another way of describing a physical variable is to specify it as a functional, whose special type is called a distribution. It turns out that the distribution concept provide a better mechanism for analyzing certain physical phenomena than does the function concept. By using wavelets with high regularity we give a resolution of functions with slow growth.

A dual algorithm based on the smooth function proposed by Polyak (1988) is constructed for solving nonlinear programming problems with inequality constraints. It generates a sequence of points converging locally to a Kuhn-Tucker point by solving an unconstrained minimizer of a smooth potential function with a parameter. We study the relationship between eigenvalues of the Hessian of this smooth potential function and the parameter, which is useful for analyzing the effectiveness of the dual algorithm.

Teacher knowledge needed for teaching is bound to be revealed in teaching the subject matter in relation to the given instructional context. Given this, recent studies on mathematics teacher knowledge tend to analyze actual Mathematical Knowledge in Teaching [MKiT]. This study focused on the dimension of transformation and its related codes in Knowledge Quartet, which has been recognized as a MKiT framework, and analyzed a Korean teacher's transformation knowledge revealed in her elementary mathematics teaching. The analysis showed that the codes related to the dimension of transformation were useful in analyzing teacher knowledge in the Korean context. However, a few codes need to be revised or added for more suitability. On the basis of these results, this paper closes with implications for analyzing teacher knowledge in mathematics teaching.

The purpose of this study is to search whether mathematical beliefs have changed when new social norms are formed in math classroom through research using survey papers about mathematical beliefs and math class video photographing. In addition, it would search for social norms of mathematical classroom which affects to students' mathematical beliefs by analyzing culture of mathematical classroom. The result was that the class focusing only general social norms wasn't enough to change students' mathematical beliefs. And as we have examined sociomathematical norms of math classroom through analyzing culture of mathematics classroom, it has affected students' mathematical beliefs.

In this paper, we investigate the methodology to calculate the volume of sphere in SanHakSeos. Comparing and analyzing content in Korean and Chinese mathematics education textbooks that uses as a foundation the aforementioned methodology, it is proposed that in future development of mathematics education curriculum the area of solid geometry be taught in greater depth in basic study guides.

Because all areas of mechanical engineering involves the use of mathematics, mechanical engineers need mathematical understanding and skill enhancement. To achieve the effective mathematics education for mechanical undergraduate students, it should reorganize the important subtopics of mathematics. In this paper, we explore the direction of the development of mathematics education for mechanical engineers by analyzing the teaching hours of each topics in the mathematics and by comparing the results with significance analysis of expert survey. To do so, syllabuses of mathematics courses of the selected mechanical engineering departments were analyzed and the survey responses of professionals in the Korean Society of Mechanical Engineers were also investigated. Finally, the revision of mathematics curriculum in the mechanical engineering was proposed.

Teachers and students' knowledge of zero was investigated through data collected from 16 preservice secondary mathematics teachers and 20 gifted secondary school students. Results showed that these teachers and students had an inadequate knowledge about zero. They exhibited a reluctance to accept zero as an attribute for classification, confusion as to whether or not zero is a number, and stable patterns of computational error. Although leachers and researchers have long recognized the value of analyzing student errors for diagnosis and remediation, students have not been encouraged to take advantage of errors as learning opportunities in mathematics instruction. The article suggests using errors as springboards for inquiry in action, discusses its potential contributions to mathematics instruction by analyzing students and preservice teachers errors related to zero.
