Among the adaptive noise cancellers (ANC), the least mean square (LMS) algorithm has probably become the most popular algorithm because of its robustness, good tracking properties, and simplicity of implementation. However, it has non-uniform convergence and a trade-off between the rate of convergence and excess mean square error (EMSE). To overcome these shortcomings, a number of variable step size least mean square (VSSLMS) algorithms have been researched for years. These LMS algorithms use a complex variable step method approach for rapid convergence but need high computational complexity. A variable step approach can impair the simplicity and robustness of the LMS algorithm. The proposed instantaneous gain control (IGC) algorithm uses the instantaneous gain value of the original signal and the noise signal. As a result, the IGC algorithm can reduce computational complexity and maintain better performance.

This study provides a new fashion design perspective that is rapidly changing and pursues a new one based on maximalism, which is a trend that expresses the sensibility of modern fashion that seeks originality and differentiation in today's fashion world. In this study, based on the domestic monographs and previous studies, the concept and formation background of maximalism are theoretically examined. We want to classify and analyze characteristics based on the analysis and collection image analysis using the internet specialist site (www.vogue.com). We also develope a fashion design that is applied to clothes after deriving typical characteristics. The study results are as follows. The criterion of Maximilian's type criterion required to escape the minimalism that pursues simplicity and simplicity is the need to express the enlargement that expresses exaggeration, decoration to express glamor, the mixture that expresses the mixture and the complexity of the heterogeneous. This then can show the characteristics of the expressed non-structure. We analyzed the formative characteristics of maximalism in modern fashion and developed five types of fashion design.

Personal Digital Assistants (PDAs) have become ubiquitous and continued to gain popularity. Since PDAs have some special contexts such as mobility and limited screen size, icons are utilized frequently because icons allow us to do tasks more rapidly and effectively on PDAs like another information appliances. The study presents a cognitive approach to study human factors affecting icon design with multidimensional Scaling (MDS) analysis. In the experiment, a real PDA was used to investigate 29 attributes and2 preference ratings for 22 PDA icons by 20 Korean subjects. As a result, cognitive positioning about icons, attributes, and preference data were arranged on the two dimensional perceptual map. Attributes were grouped by simplicity, universality, activity, complexity, abstraction, static, and alphanumeric time. Subjects preferences were highly related with simplicity attributes group and positive to universality and activity attributes groups. It was also confirmed that there are some icons unfitted to the mental model of Korean. However, when icons are designed for PDAs or similar information appliances to Korean, it should be designed simply and actively with universal image fitted on target users mental model.

The purpose of this study is to identify the architectural construction of Balenciaga's works. He was perfectionist in tailoring which was based on architectural thought, and couturier who could design, cut, sew and fit a whole gar-ment. Balenciaga has never followed any fashion trend but his own. He designed from within himself, according to his own sensitivity to fashion. Like Chanel, he mad clothes in which women can be comfortable, move in, and get on and off with a minimum of effort. He ap-plied radical shapes to flattering ends, for his clothes echoed movements and gestures, never determined them. He achieved the perfect harmony between the body and the garment, freeing the spirit of the woman within. Reflec-tion his respect for women, Balenciaga never contorted or restriced their bodies. He did not depend on hoops and petticoats to hold out the skirts of his evening dresses but on well-balanced, architectural construction. Therefore in order to identify the architec-tural consturuction, this study hypothesizes (1) the effect of mass and volume, (2) the ef-fect of weight and support, (3) the effect of complexity and simplicity, (4) the effect of line and rhythm etc. The architectural beauty of form in Balenciaga's works are especially based on simplicity and support.

Recently, the aspect of consumers' preference for design has been changed to a pattern of respect for personality, based on 'personal value of passion'. The differentiated personal passion of modern people does not allow them to select mass-produced industrial product, and leads them to choose life style different from others. Specially, consumers want to express. their differentiated personality by preferring and possessing the originally designed products. Therefore, the originally designed products that are clearly identifiable become the object of consumers' consideration, and stimulate the consumers' desire to purchase. According to new needs of consumers, it is required to reconsider the old design pattern of furniture based on simplicity and propose new design for furniture to meet the needs of consumers. Mass production has resulted in a strong focus on simplicity rather than difficulty and complexity of the production process. This tendency shows the design pattern that leans toward one side excluding the expression of correlative concept among design elements. This one sided design leads modern people to have no personality, and shows only simple and uniform expression of passion. Therefore, this paper is purposed to develop furniture with more personality by applying correlative concept that has been taken less seriously in the field of design to furniture design.

Census transform is one of the stereo vision methods which is robust to radiometric distortion and illuminance change. This paper proposes a hybrid census transform using the mini census transform and the generalized census transform concurrently. This method uses simplicity of mini census transform and noise feature of generalized census transform together. This paper performed stereo matching containing post processing to evaluate each methods. The result shows that hybrid census transform has similar performance to generalized census transform and mean value of calculation complexity between mini census transform and generalized census transform.

This paper showed the convergence rate and the performance of interference cancellation using Applebaum and DMI algorithms in adaptive sidelobe canceller. Applebaum algorithm is used widely due to simplicity but it has a slow convergence rate and the problem of eigenvalue spread. DMI algorithm converges rapidly but has computational load and hardware complexity. We compared the performance and complexity using Applebaum and DMI algorithms in Adaptive SLC that requires rapid convergence rate and the performance and conclude that DMI algorithm is more efficient for adaptive SLC.

Apparel goods are classified by many criteria for ease of merchandising implementation. Fashion and basic goods are also an oucome oi classification. Previous studies pnvide some criteria by which apparel products can be classified into fushion and basic goods. Among those ciiteria, seasonality, fashionability, clothing types, complexity in pnduction, simplicity of style, pioducuon volume, degree of style change by season, could be listed. This study, first explored how apparel merchandisers and designers define fashion and basic goods in relation with those criteria. Definitions of fashion and basic goods were explored in terms of design elements (i.e., style, color, material), production volume, sales ratio, proportion in product assortment, and contribution to profit. The study adopted a qualitative approach by use of eighteen infepth interviews with menhandisers and designers. Six were from women＇s wear brand, Seven from men＇s wear brand, and 5 from casual wear brand. All the interviewees agreed that they are using the classification of basic vs. fashion goods. However, they are using diverse terms to indicate the basic and fashion goods. The interviewees defined each group based on its contribution to total sales or profit complexity in design, production volume, and style change by season. Basic goods had a higher level of production quantity, contribute more to profit simpler design, and less style change by season than fashion goods.

The decision-directed blind equalization algorithm is often used due to its simplicity and good convergence property when the eye pattern is open. However, in a channel where the eye pattern is closed, the decision-directed algorithm is not guaranteed to converge. Hence, a modified Bussgang-type algorithm using a hyperbolic tangent function for zero-memory nonlinear(ZNL) function has been proposed and applied to avoid this problem by Filho et al. But application of this algorithm includes the calculation of hyperbolic tangent function and its derivative or a look-up table which may need a large amount of memory due to channel variations. To reduce the computational and/or hardware complexity of Filho's algorithm, in this paper, an improved method for the decision-directed algorithm is proposed. In the proposed scheme, the ZNL function and its derivative are respectively set to be the original signum function and a narrow rectangular pulse which is an approximation of Dirac delta function. It is shown that the proposed scheme, when it is combined with decision-directed algorithm, reduces the computational complexity drastically while it retains the convergence and steady-state performance of the Filho's algorithm.

All vague and constructions of contemporary cultural environment have been reorganized and the relationship between people and culture can't follow development speed of rapid material civilization development and being informationalized. Because of the circumstances, physical environment is changing into other cultural environment, existence of human being is at a crisis. Physical value precedes mental value and rapid changing causes culture lag. Modernism design of 20th century suggested standard, simplicity and mass production methods, but nowaday, as human being complexity is increasing, information-media are needed to satisfy that. Namely usual design thoughts have to be changed because our life is surrounded by many kinds of powerful media sings and various mixed cultural circumstances. People predict that the characteristics of new ages are 'Immateriality', 'Sensoriality', 'multimedia'. Amongst them, medial spatial characteristics will be eventually remarkable in commercial space which is coincided with economic logic and multilateral culture. This study is a focus on commercial space which emphasis contemporary medial characteristics and observes medial meaning and various technique through some experimental works in Korea. Also this study's purpose is to examine design directions which correspond with contemporary Korea culture.
