This research aimed at a clear definition of simplicity and complexity and other elements of product aesthetics and investigated the influence of simplicity/complexity on consumer preference, and balance. The research also made it an objective to find answers to underlying questions of whether there is a relationship between simplicity/complexity, and balance, and if there is, then how is the relationship? and is balance in a product's aesthetics an influential factor? does a relationship exist between consumer preference, simplicity/complexity, and balance? In conclusion, the research process categorized products into groups by use of FCB Grid, and analyze4 each group to establish a prototype which represents the group, then questionnaires where presented to consumers in order to find satisfaction to consumer preference. Also, the research proposes a verification method through design process.

This research basically defines that relationship among simplicity/complexity, other product aesthetics and consumer preference. The goal of this research is to find answer 'How much the simplicity/complexity influence expressed functional shapes on products?' and 'What is relationship between simplicity/complexity and consumer preference?' This is process that first we make categorize products by analysis, and second we analyze each category group for fading propensity from consumers, and finally we verify through design process.

This research, which is quite different from previous studies, has tried to understand the relationships among aesthetic dimensions, on the basis of product aesthetic and how these consumer preferences change according to changes of these dimensions. For this research, the factors of simplicity/complexity and balance among many aesthetic elements were chosen through experiment, and products which are on the market were divided into 4 categories with the FCB Grid. Two products of each respective category were selected and a typical model was chosen for each other. These models were changed only with the factors of simplicity/complexity and balance, in order to make a show-card. The relationships between simplicity/complexity, balance, and consumer preferences has been proven with the show-card. The measured value change of consumer preferences will be provided for design development as basic data. The relationship among the various aesthetic dimensions will improve through consistent research.

Least mean square adaptive algorithms have played important role in radar, sonar, speech processing, and mobile communication. In mobile communication area, the convergence rate of a LMS algorithm is quite important. However, LMS algorithms have slow and non-uniform convergence rate problem For overcoming these shortcomings, various variable step LMS adaptive algorithms have been studied in recent years. Most of these recent LMS algorithms have used complex variable step methods to get a rapid convergence. But complex variable step methods need a high computational complexity. Therefore, the main merits such as the simplicity and the robustness in a LMS algorithm can be eroded. The proposed deterministic variable step LMS algorithm is based upon a simple deterministic function for the step update so that the simplicity of the proposed algorithm is obtained and the fast convergence is still maintainable.

The purposes of this study were to investigate used patterns in Hanbok and to find out a classification and a characteristic of motifs. The data made use of 111 pictures constituted Gegory(a Korean jacket) and Chima(a skirt) in photographs collected in wedding magazine(Wedding 21'). The data was analyzed by frequency, contents analysis. Pattern's use or not in Hanbok and a sort, a arrangement, a way of expression of patterns using frequency Classified and characteristics of motifs were analyzed contents analysis. The results of this study were as follows. First, a sort of patterns was lots of flower motifs of the plant pattern. An arrangement of and expression of patterns used mainly a partial arrangement and embroidery expression. Second, the subjects classified using criterion of classification of a external feature, forms of expression, and simplicity/complexity of line. Third, the motifs classified into plants, an animal, geometry, abstraction, and a natural object. The plant motifs were perceived the focus of flower, a combination of a flower and a stem in the plant motifs. The subjects perceived as a simplicity/complexity of flower and a drawing line of a flower and a stem.

Perception between real object and recognized subject of human on objective subject is not the same. The reason Is that individual perception of visual design components are transmitted as the image of whole. It is required process of visual perception. Therefore, I developed the vision of seeing image of pattern which is based on Gestalt visual perception theory in clothes. The summary of this study's results is like followings. Extremely antagonistic terms which are specialized by formative characteristics of formative components are clearness and blur of outline/ fixed shape and non-fixed shape/ visuality and tangibility of representation/ simplicity and complexity of structure/ invariability and variability of mobility/ symmetry and asymmetry of arrangements singularity and plurality of group number. The expression of motive shows that clearness, fixed shape, visuality and simplicity pursuit Determination image, and blur, non-fixed shape, tangibility and complexity pursuit Ambiguity image. The arrangements of motive shows that invariability, symmetry and singularity pursuit Order image, and variability asymmetry and plurality pursuit Disorder image. Therefore, the standard of the coordinator of Pattern image positioning is established as Determination and Ambiguity of motive are X-axis, and Order and Disorder of pattern are Y-axis. As the frame of Pattern image positioning, four separated dimensions have made.

Capacitive power transfer has an advantage in the simplicity of the energy link structure. So, the conventional phase -shift full bridge sometime is not always the best choice because of its complexity and high cost. On the other hand, the link capacitance is usually very low and requires high-frequency operation, but, the series resonant converter loses zero-voltage switching feature in the light load condition, which makes the switching loss high especially in CPT system. The paper proposes a new low-cost topology based on asymmetric half-bridge to achieve simplicity as well as wide zero voltage switching range. The design procedure is presented, and circuit operations are analyzed and verified by simulation.

The three-step search (TSS) algorithm for block motion estimation has been widely used in real-time video coding due to the simplicity of the algorithm significant reduction of computationl cost and good performance. In this paper an improved three-step search (ITS) algorithm is proposed to improve the performance of the TSS algorithm. Simulation results show that in terms of motion compensation errors the proposed ITSS outperforms some popular fast search algorithms while it has the lower computational complexity.
