In this paper, we present a symbolic formulation of the error obtained due to an approximation of a given function by the mixed-interpolating function. Using the proposed symbolic method, we compute the error evaluation operator as well as the error estimation at any arbitrary point. We also present an algorithm to compute an approximation of a function by the mixed interpolation technique in terms of projector operator. Certain examples are presented to illustrate the proposed algorithm. Maple implementation of the proposed algorithm is discussed with sample computations.

The main purpose of this study was to investigate the elements which influence the symbolic consumption in clothing. Materialism and agent of socialization have been studied and the affect of these two are also developed. The theoretical study and survey methods were used. The survey was administered to 426 women in their twenties living in Seoul and Kyungki region. SPSS packages were applied to find out the results of ANOVA Duncans multiple range tests, means, standard deviation, factor analysis, and regression analysis. The major findings of this study could be summerized as follows; First, the subordinate parts of symbolic consumption was divided into these three parts; fashion oriented consumption, brand oriented consumption, hedonic consumption. The average of hedonic consumption was higher than other subordinate parts of symbolic consumption. Second, symbolic consumption was seemed to have the differences according to materialism and its subfactors. The higher materialism indicated, the higher symbolic consumption was. Third, symbolic consumption was proven to have the differences according to agent of socialization such as reference group and mass media. The higher the influence of the reference group and mass media was, the higher symbolic consumption was. Fourth, according to the results of the regression analysis examing the relative influences of variables affecting symbolic consumption in clothing, the influence of the reference group was the most important variable. The influence of mass media and materialism was related positively to the symbolic consumption.

The objectives of this study are to examine the degree of propensity for symbolic consumption among adolescents and its factors, and to investigate the effects of demographic variables - sex, grade, father's education, mother's education, father's job, mother's job, monthly allowance, monthly household income - self-esteem, and socialization agents variables - parents, friends, mass media - on the propensity. In this study, the propensity for symbolic consumption is defined as the propensity to consume products through their affective, subjective, and symbolic value rather than through their practical and utility value. The data used in this study were collected from 509 adolescents who are in the 2nd grade of middle or high schools in Pusan. The research results can be summarized as follows: 1. The propensity for symbolic consumption were found to have significant differences according to sex, father's education, mother's education, mother's job, and monthly allowance. 2. It differs significantly according to adolescents' self-esteem. That is, the lower self-esteem adolescents have, the higher propensity for symbolic consumption they show. 3. It also differs significantly according to the degree of communication with parents, the degree of accepting friends' view, the degree of communication with friends, the degree of informative influence from friends, and the degree of taking in mass media.

Nowadays computers can perform symbolic computations in addition to mere number crunching operations for which they were originally designed. Symbolic computation opens up exciting possibilities in Structural Mechanics and engineering. Classical areas have been increasingly neglected due to the advent of computers as well as general purpose finite element software. But now, classical analysis has reemerged as an attractive computer option due to the capabilities of symbolic computation. The repetitive cycles of simultaneous - equation sets required by the finite element technique can be eliminated by solving a single set in symbolic form, thus generating a truly closed-form solution. This consequently saves in data preparation, storage and execution time. The power of Symbolic computation is demonstrated by six examples by applying symbolic computation 1) to solve coupled shear wall 2) to generate beam element matrices 3) to find the natural frequency of a shear frame using transfer matrix method 4) to find the stresses of a plate subjected to in-plane loading using Levy's approach 5) to draw the influence surface for deflection of an isotropic plate simply supported on all sides 6) to get dynamic equilibrium equations from Lagrange equation. This paper also presents yet another computationally efficient and accurate numerical method which is based on the concept of derivative of a function expressed as a weighted linear sum of the function values at all the mesh points. Again this method is applied to solve the problems of 1) coupled shear wall 2) lateral buckling of thin-walled beams due to moment gradient 3) buckling of a column and 4) static and buckling analysis of circular plates of uniform or non-uniform thickness. The numerical results obtained are compared with those available in existing literature in order to verify their accuracy.

This paper aims to revisit William Faulkner's Absalom, Absalom! by focusing on the corporeal body and its role in dismantling the Southern ideology of white patriarchy. The latter, which is represented by Thomas Sutpen and his attempt to establish a white male dynasty, is a symbolic space in which the corporeal body turns into a symbolic one through the process of inscribing social ideologies on it. However, this symbolic space is also a contending site between the two bodies. The symbolic body of Sutpen cannot entirely erase its corporeal traces, and therefore the corporeal body, which is buried but nonetheless existent, threatens to undermine rules and premises of the symbolic order. Given that, this paper approaches Faulkner's critique of the Southern white patriarchal ideology from the tension that the corporeal body and the symbolic body create. The 'flesh' roughly corresponds to racial and sexual otherness, namely black flesh and the homoerotic desire of male body. Although they-as the matter of race and that of gender - function in different levels of signification, they still share a common purpose in revealing the logical paradox within Sutpen's symbolic order. The idea of pure whiteness that Sutpen subscribes to is a concept that prerequisites the existence of blackness. Likewise, his idea of male homosociality based upon patriarchal legacy stands precariously on the verge of disintegrating into homoetoricism. As internal otherness that Sutpen's symbolic order cannot fully incorporate, the corporeal body functions to indicate the limitation of Sutpen's Design and its body-signification process.

We introduce the notions of symbolic expansivity and symbolic shadowing for homeomorphisms on non-metrizable compact spaces which are generalizations of expansivity and shadowing, respectively, for metric spaces. The main result is to generalize the Smale's spectral decomposition theorem to symbolically expansive homeomorphisms with symbolic shadowing on non-metrizable compact Hausdorff totally disconnected spaces.

The present study examined the symbolic levels of early pretense in 67 children from 19 to 48 months of age. Subjects were selected from 3 non-profit, play oriented daycare centers. Children were observed during free play. Age and sex differences were examined with 2-way ANOVA performed on case analyses of individual children. Results showed that the symbolic level of pretense increased with age, but no significant sex differences were found. Some children below 2 years of age showed high levels of symbolic play, presenting the possibility of high levels of representational thinking from this early age.

We propose a novel hierarchical clustering for distribution valued dissimilarities. Analysis of large and complex data has attracted significant interest. Symbolic Data Analysis (SDA) was proposed by Diday in 1980's, which provides a new framework for statistical analysis. In SDA, we analyze an object with internal variation, including an interval, a histogram and a distribution, called a symbolic object. In the study, we focus on a cluster analysis for distribution valued dissimilarities, one of the symbolic objects. A hierarchical clustering has two steps in general: find out step and update step. In the find out step, we find the nearest pair of clusters. We extend it for distribution valued dissimilarities, introducing a measure on their order relations. In the update step, dissimilarities between clusters are redefined by mixture of distributions with a mixing ratio. We show an actual example of the proposed method and a simulation study.

We propose a rigorous and practical methodology to evaluate the performance of symbolic manipulation program such as Mathematica, Maple, and Maxima. First, we demonstrate an inverse method to construct the benchmark problems of an initial value problems. The benchmark problems associated with the discrete version of the Chebyshev polynomials provide a rigorous and objective measure to evaluate the performance of symbolic manipulation programs. We compare three symbolic manipulation programs, which are Mathematica, Maple and Maxima, using this methodology. The computation time, the used memory and the perturbation terms are chosen for comparison parameters.
