When it calculates the optimum price of filter coefficient, the many operation quantity is necessary. Is like that the real-time control is difficult and the hardware embodiment expense is big. The case which does not know advance information of input signal or the case where the statistical nature changes with change of surroundings environment is necessary the adaptive filter. Every hour to change a coefficient automatically and system in order to reach to the condition of optimum oneself, the fact that is the adaptive filter. When it does not the quality of input signal or it does not know the environment of surroundings every hour changing, it does not emit not to be, in order to collect, the fact that is the adaptive filter. The case of the Acoustic Echo Canceler does thousands filter coefficients in necessity. It reduces a many calculation quantity to respect, it uses the IIR filter from hour territory. Also it uses the block adaptive filter which has a block input signal and a block output signal. The former there is a weak point where the stability discrimination is always demanded. Consequently, The block adaptive filter is researched plentifully. This dissertation planned the block MADF adaptive filter used to MADf algorithm.

As essential element of designers, foundation studies program helps student deal with the individual expression of imagination and variety of correspondence for solving design problem through the understanding of 2-D, 3-D basic design elements, principals, structures. Liberal art and foundation studio courses provides embodiment and settlement of design principal through the foundation studies expand to experiences systematically and deeply. After the Industrialization, foundation studies have developed from Bauhaus in German, the courses have been progressing and systematizing with the demand of time in United States. Growth of Industrialization, expanded design areas departmentalized to various of fields, then the segmentation of foundation courses tend to important than basic design courses. The introduction of information era, the appearance of computer is placed as a tool of design development and added to applied basic courses. This study is intended to know how to change the leading foundation courses in United State due to the revitalization of industrialization and information through the research and analyse to foundation design education curriculums. As a result, most of design school in United States provide drawing, 2-D, 3-D, and 4-D courses included 3-D design element as a basic studies and provide to students introduction to fundamental principal of design concept and communication in both theoretical and applied form.

This paper aims to provide pragmatic application guidelines of the interior finish materials for apartment houses with newly-established evaluation methodology of the sustainable degree of interior products. With reference to the standards and criteria of domestic eco-labeling accreditation schemes for sustainable products in the area of architecture which focus on the sustainable elements classified as the health, recyclability, durability, and energy efficiency, in this study, a systematic evaluation method has been established for interior finish products with quantifiable indicators for sustainable performance. Base on the evaluation system introduced here, most interior finish products can be classified into a database and applied effectively to the realities from the perspective of the sustainability. There are the necessities of enforcement issues with the idea of revising or taking remedial measures of the current performance criteria of domestic eco-labeling accreditation to bolster their reliability. As well as already-commercialized products, hereafter, continued efforts are needed to control the whole process of manufacturing new interior finish products from their designing, constructing, consuming, recycling and to dismantling in terms of sustainability, which promises more pragmatic follow-up measures for the detail embodiment of the environment-friendly spaces.
