This paper addresses the vertical class fragmentation in distributed object-oriented databases. In the proposed vertical fragmentation, after producing the attribute fragment by partitioning attributes, then the method fragment is produced by gathering methods referring the attribute in each fragment. For partitioning attributes, we define query access matrix(QAM) and method access matrix(MAM) to express attributes that method refers, and extend QAM, MAM and attribute usage matrix(AUM) to universal class environment for representing relationship among other classes through class hierarchy and class composite hierarchy.

In this paper, we propose a randomized response model with discrete quantitative attribute by three-stage cluster sampling for obtaining discrete quantitative data by using the Liu & Chow model(1976), when the population was made up of sensitive discrete quantitative clusters. We obtain the minimum variance by calculating the optimum number of fsu, ssu, tsu under the some given constant cost. And we obtain the minimum cost under the some given accuracy.

In this paper, we explore a new data mining capability that is based on Quantitative Attribute and Time Series. Our solution procedure consists of two steps. First, We derive an algorithm to contain the Quantitative Attribute into a set of candidate item. Second, We redefine the concepts of confidence and support for composite association rules. It is shown that proposed methode is very advantageous and can lead to prominent performance improvement.

The subject of nonlinear control is an important area of automatic control. The behavior of nonlinear systems is much more complex. If the operating range of a control system is small, and if the involved nonlinearities are smooth, then the control system may be resonably approximated by a set of linear differential equations. This paper presents the deadbeat response attribute of some nonlinear systems, e.g., magnetic levitation, pendulum, van der pol oscillator etc.. The studied results through the computer simulation are shown a promising attribute of deadbeat response that the outputs of the systems are reached relatively fast the steady state.

A salient identity influences individuals' judgment on products. The current research investigates why identity salience sometimes produces asymmetric effects on an individual's judgment such that a salient identity often influences judgment on identity-congruent products only or identity-incongruent products only. Across two experiments, this research proposes and shows that the valence of identity-incongruent and identity-congruent attributes determines the direction of the asymmetric identity salience effects. Specifically, when an attribute of an identity-incongruent product is positively- (negatively-) valenced, identity salience influences judgment through a decreased (increased) preference for the identity-incongruent (identity-congruent) product.

The purpose of this study is to clarify the cause and effects of evaluation attribute, visitor's satisfaction and behavioral intentions focused on Busan International Film Festival(BIFF). To achieve the study objective, 277 valid questionnaires were statistically analyzed, using frequency analysis, exploratory factor analysis, confirmatory factor analysis, reliability analysis and path analysis. The results show that the evaluation attribute of local festival exerts a positive influence on visitor's satisfaction and behavioral intention. Second, visitor's satisfaction had positive effects on behavioral intention. The regional festival can vary depending on the visit is satisfied. Consequently, it was revealed how evaluation attribute is in the visitor's satisfaction and behavioral intention in local festival.
