Circuit configurations for realizing of biquadratic current transfer functions using current conveyors (CCIIs) are presented. The circuits are composed of three multiple-output CCIIs and four passive elements (two resistors and two grounded capacitors), and when current controlled conveyors (CCIIs) in place of CCIIs are employed, the circuit can be realized using three multiple-output CCIIs and two grounded capacitors. Use of grounded capacitors is suitable for integrated implementation. The cutoff frequency of a realized filter with current gain K can be tuned independently of Q by the value of K.

The e-business strategies ultimately Pursue creating the maximal value for customers through the competitive advantages and business opportunities newly created on the basis of information technologies. For the realization of e-business strategies, the successful implementation and operation of e-business system must be the crucial activities in and out of an organization. Therefore, in physical world, there were lots of interests that what kind of key factors can lead the success of e-business system. Moreover, in the field of academia also, there have been many research results for investigating and finding out the key success factors for e-business system. However, the perceptual level of the significance of key success factors that organization members perceive can be changed over each phase of system life cycle such phases as introduction, growth, maturity, and decline. This study investigated that there might be significant differences in the perceptual level regarding importance of success factors among phases of system life cycle.

This paper presents Spectral-Domain optical measurement system using self-fabricated CCD sensor driver. The light source is a high brightness white LED and the detector is a 2048 array typed CCD image sensor. I have fabricated the CCD sensor driver to generate four pulse signals, which are the CCD-driving pulses. Using this Spectral Domain optical measurement system, the distance value between the reference mirror and the sample mirror can be obtained successfully.

From designers' viewpoint, today, the major environmental change can be found in the digital environment. Especially, more than the development of physical product which can be characterized as the backup of old function and realization of new function in the field of product design, as the digital product development of program style that exists without substance is deepened, the development of the digital design media has been accelerating. However, it is the recent matter that the link with educational system about the added value which could be embodied by digitech, and the interdisciplinary research about producing goods become regular. The construction of the industrial design development process based on the digital environment must be the major research object. Therefore, the goal of my research is to present the concept of the product design process model required in the digital environment.

This paper concerned about a imputed color printed material image in camera to decrease noise and distortion by processing median filtering with input image to identical condition. Also this paper proposed the way of compares a normal printed material with an abnormal printed material color tone with trained a learning of the error back-propagation to block classification by extracting five place from identical block(3${\times}$3) of color printed material R, G, B value. As a representative algorithm of multi-layer perceptron the error Back-propagation technique used to solve complex problems. However, the Error Back-propagation is algorithm which basically used a gradient descent method which can be converged to local minimum and the Back Propagation train include problems, and that may converge in a local minimum rather than get a global minimum. The network structure appropriate for a given problem. In this paper, a good result is obtained by improve initial condition and adjust th number of hidden layer to solve the problem of real time process, learning and train.

Manners is important factor of healthy family life and helps to form diverse human relationship properly at university and society. The main purpose of this research was to emphasize the importance of manners by examining university student's conduct of manners which is basically demanded for harmonious social life and progressive human relationship. First, the health level of the conduct of the subject students appeared to exceed the average. Second, as a result of examining conduct of manners and strengths of healthy family life, it has been analyzed that humanitarian value, number of siblings and realization of the significance of the healthy family life are serious variables. Third, it has been analyzed that the higher the level of university student's conduct of the manner of family life, the higher the level of strengths of healthy family life.

This paper deals with the microcomputer realization of EMG pattern recognition system which provides identification of motion commands from the EMG signals for the on-line control of a prosthetic arm. A probabilistic model of pattern is formulated in the feature space of integral absolute value(IAV) to describe the relation between a motion command and the location of corresponding pattern. This model enables the derivation of sample density function of a command in the feature space of IAV. Classification is caried out through the multiclass sequential decision process, where the decision rule and the stopping rule of the process are designed by using the simple mathematical formulas defined as the likelihood probability and the decision measure, respectively. Some floating point algorithms such as addition, multiplication, division, square root and exponential function are developed for calculating the probability density functions and the decision measure. Only six primitive motions and one no motion are incorporated in this paper.

This study explored the literature review for intending to make contemporary furniture expressed as postmodern aesthetics accessible to the broadest possible public, particularly through an examination and realization of art and everyday life, using qualitative analysis about the related literature as the principal methodology. The postmodern furniture aesthetics of communication expressed through double-coding, which was seen by Charles Jencks as the defining element of Post-Modernism, is characterized by the use of ideas from the traditions of craft. Hence, I dealt with pre-Modern furniture and Modern-furniture aesthetics as the background of postmodern furniture called New design furniture. As a result, contemporary furniture called New design furniture represented the use of ornament, craftsmanship, or beauty from the traditions of craft, which was a main source for communication value in postmodern furniture aesthetics.

Korean elementary school facilities are a lot of changes since the mid-1990s. Creative learning ability to become more important. Interior space environment and the hardware changes needed improvement. In this study, depending on the teaching methods and curriculum characteristics to suggest design guidelines for a more effective lesson plan by changing the terran out. Open education free to enhance the development and creativity of the human spirit, the human, and realize the value of education is to increase the relevance of education for self-realization and social. Space for open educational practices through advanced layout is proposed. There is a need for the development of new school furniture for a variety of lay-out. It is important to develop a spatial variability in new school furniture.
