The clinical assessment for preschool children who are known to have problems in selfreporting tends to be dependent on outsiders' reporting. Thus, the direct assessment of children's inner experience, thoughts and feelings is difficult. MacArthur Story-Stem Battery(MSSB) developed to learn more about preschool children's mental representation in play is used in this study to help assess clinical preschool children through developmental study of normal children's mental representation. Fifty five children(32boys and 23girls) who performed MSSB, IQ Test, Peabody Picture Vocabulary Test-Revised(PPVT) were videotaped and were analyzed. The results of this study were as follows：1) Children frequently displayed negative mental representation such as atypical negative response, reparation/guilt, punishment, personal injury and so on during emotionally laden play situation. 2) Mental representation of parent appeared positive, disciplinary, and negative in respective. 3) As a result of factor analysis of MSSB content themes, aggressive, prosocial, and oppositional content theme composites were generated. Aggressive content included atypical negative response, aggression, personal injury, and exclusion. Prosocial content included affection, affiliation, and reparation/guilt. Oppositional content included punishment and non-compliance. 4) Mental representation of parent and content themes showed significant correlation. Positive, negative, and disciplinary representation were significantly correlated for prosocial(r=0.40), aggressive (r=0.52), and oppositional(r=0.75) content theme respectively. 5) Among the correlations between parental mental representations and emotional responses, positive parental representation and anxiety showed significant negative correlation(r=-0.43). 6) Among the correlations between content themes and emotional responses, there were significant positive correlations between aggressive(r=0.28) and oppositional content themes(r=0.29) and distress, and were significant negative correlations between prosocial content theme and concern(r=-0.29) and anxiety(r=-0.43). According to the above results, preschool children frequently displayed negative mental representation in emotionally conflictual play situation. Children with more prosocial themes in their stories exhibit more positive parental mental representation. Also, children with more aggressive themes tend to display more negative parental representation and negative emotional responses.

Based on translation models, both Gaussian and non-Gaussian wind fields are generated using spectral representation method for investigating the influence of non-Gaussian characteristics and directivity effect of wind load on fatigue damage of wind turbine. Using the blade aerodynamic model and multi-body dynamics, dynamic responses are calculated. Using linear damage accumulation theory and linear crack propagation theory, crack initiation life and crack propagation life are discussed with consideration of the joint probability density distribution of the wind direction and mean wind speed in detail. The result shows that non-Gaussian characteristics of wind load have less influence on fatigue life of wind turbine in the area with smaller annual mean wind speeds. Whereas, the influence becomes significant with the increase of the annual mean wind speed. When the annual mean wind speeds are 7 m/s and 9 m/s at hub height of 90 m, the crack initiation lives under softening non-Gaussian wind decrease by 10% compared with Gaussian wind fields or at higher hub height. The study indicates that the consideration of the influence of softening non-Gaussian characteristics of wind inflows can significantly decrease the fatigue life, and, if neglected, it can result in non-conservative fatigue life estimates for the areas with higher annual mean wind speeds.

The Cyber-Physical Systems (CPS) complexly perform modeling and simulation (M&S) for the various embedded systems. In this case, due to use diverse formatted models, we suggest to apply with the SEDRIS to systematically manage the different formatted data on M&S. The SEDRIS can reduce time and cost with reusing and interoperating environment data developed in the specific domain. To do this, we should input the data transformed the height map for terrain representation in a simulator into raster data of SEDRIS for which interoperate between the existed simulator and the SEDRIS. To solve the problem, we propose the transformation method to transfer the polygon data from RAW file used in terrain representation. With the proposed method, we can provide two advantages. First, it can possibly express the environment data into SEDRIS. Second, we can see the terrain like an image file through a viewer. Therefore, even non-expert easily constructs the terrain environment data.

In the late nineteenth century, British colonial activities became aggressive and annexationist in the tropics, including the Southeast Asian Archipelago, which reflected the historical circumstances of both increasing resistance from the indigenous and severe competition among European powers. Interestingly, the change in English colonial policy toward an annexationist or imperialist vision adopted the motto of a civilizing mission, which was founded on the anthropological assumption that the white English were civilized, while the non-white indigenous were savage. The assumption developed into colonial discourse through systematic gathering of anthropological knowledge about the peripheries of the Empire. The knowledge system was flawed, which stressed the differences of the peripheral populations from the English and served as an inverted discourse on the Imperial Self rather than the description of the Other. Furthermore, the natives were heterogeneous, which rendered indistinct the racial and cultural differences between the English and the natives. Still, the aboriginals called Malays, who were comprised of many ethnic subgroups, needed to be deemed savage or inferior by the English in order to justify the English civilizing work or imperial ambition. Put differently, the representation of the English as civilized necessitated the (mis)representation of the natives as savage. In this context, Clifford's works contribute to systematic misrepresentation of the Malays, on which colonial discourse is founded, though not without self-contradiction. On the other hand, Conrad's novels that are set in the Malay Archipelago resort to a strategic misrepresentation that reveals the relativity of the discourse. Exploring the dilemma of denationalization to various degrees, Conrad's Malay texts problematize the (mis)representation of the indigenous as inferior, which is the basis of English claim to superiority.

A staple of feminist literary anthologies which was instrumental in reevaluating the writer Susan Glaspell, Trifles(1916) has received numerous comments from feminist scholars so far. Most of them tend to concentrate on the themes of female solidarity and justice challenging the androcentric system of law and order. Lacking in the plethora of thematic approaches to the play's feminist subject, however, are formal analyses considering the way in which the play's generic form assists in communicating such thematic concerns of feminism. An alternative to the typical scenario at the courtroom whose mistreatment of women must have loomed large to the young Glaspell as she revisited the old trial of a midwestern murderess which she had covered as a journalist for a local newspaper in Iowa, Trifles serves as a corrective to the courtroom dynamics offering a 'dramatic justice' as opposed to a strictly legal procedure. What this article discovers at the heart of this dramatic justice is the celebration of the unsayable, or what Wolfgang Iser termed negativity, of women's experience which has no room for reflection in the legal discourse at the courtroom tyrannized by the sayable and the evident. Examining how the dramatic form of Trifles gives a voice to the unsayable of woman's experience, which can not be properly represented at the courtroom governed by the straightforward and definitive male rhetoric, the article argues that the play is a better form than its fictional adaptation "A Jury of Her Peers"(1917) in that it syntactically suppresses the monopolizing operation of the verbal by giving precedence to the scenic and non-verbal which is constituted of setting, props, gesture and eye contacts. As a theoretical frame of reference with which to examine the modes of the unsayable in the play the article brings the concept of 'negativity,' defined by Iser as textual effects or modes of the unspeakable and unsaid, into the discussion of the taciturnity of the absent heroine and the non-verbal representation of drama.

Multiple discrete Hilbert type inequalities are established in the case of non-homogeneous kernel function by means of Laplace integral representation of associated Dirichlet series. Using newly derived integral expressions for the Mordell-Tornheim Zeta function a set of subsequent special cases, interesting by themselves, are obtained as corollaries of the main inequality.

Background: In the brain, the dominant primary motor cortex (M1) has a greater hand representation area, shows more profuse horizontal connections, and shows a greater reduction in intracortical inhibition after hand exercise than does the non-dominant M1, suggesting a hemispheric asymmetry in M1 plasticity. Methods: We performed a transcranial magnetic stimulation (TMS) study to investigate the hemispheric asymmetry of paired associative stimulation (PAS)-induced M1 plasticity in 9 right-handed volunteers. Motor evoked potentials (MEPs) were measured in the abductor pollicis brevis (APB) muscles of both hands, and MEP recruitment curves were measured at different stimulation intensities, before and after PAS. Results: MEP recruitment curves were significantly enhanced in the dominant, but not the non-dominant M1. Conclusions: These results demonstrate that the dominant M1 has greater PAS-induced plasticity than does the non-dominant M1. This provides neurophysiological evidence for the asymmetrical performance of motor tasks related to handedness.

Three-dimensional optimum design of coat-hanger die is performed using power-law and Carreau models. It is found that the three-dimensional optimum design algorithm shows good convergence with the non-Newtonian fludis. the nore realistic optimum design is accomplished by employing Carreau model with the three-dimensional design method. The effect of vixcosity modles is investigated by comparing the optimum manifold profiles and flow rate distributions of power-law and Carreau modles. Through the accurated viscosity representation of Carreau model, the effect of total flow rate on the optimum manifold profile is investigated.

A suitable representation for the conceptual simplicity of the data in statistics and signal processing is essential for a subsequent analysis such as prediction, pattern recognition, and spatial analysis. Independent component analysis (ICA) is a statistical method for transforming an observed high-dimensional multivariate data into statistically independent components. ICA has been applied increasingly in wide fields of spectrum application since ICA is able to extract unknown components of a mixture from spectra. We focus on application of ICA for separating independent sources and predicting each composition using extracted components. The theory of ICA is introduced and an application to a metal surface spectra data will be described, where subsequent analysis using non-negative least square method is performed to predict composition ratio of each sample. Furthermore, some simulation experiments are performed to demonstrate the performance of the proposed approach.

The discrete Gaussian-Hermite moment (DGHM) is a global feature representation method that can be applied to square images. We propose a modified DGHM (MDGHM) method and an MDGHM-based scale-invariant feature transform (MDGHM-SIFT) descriptor. In the MDGHM, we devise a movable mask to represent the local features of a non-square image. The complete set of non-square image features are then represented by the summation of all MDGHMs. We also propose to apply an accumulated MDGHM using multi-order derivatives to obtain distinguishable feature information in the third stage of the SIFT. Finally, we calculate an MDGHM-based magnitude and an MDGHM-based orientation using the accumulated MDGHM. We carry out experiments using the proposed method with six kinds of deformations. The results show that the proposed method can be applied to non-square images without any image truncation and that it significantly outperforms the matching accuracy of other SIFT algorithms.
