It is very difficult for the large-scale retailers, who deal with tens of thousands of items, to price all the items dynamically reflecting all the constraints and policies. In spite of its importance, the prices are determined by human experts because the process of setting the prices of all the items is not established yet. To solve this problem, we adopt a mixed model that combines three typical pricing models: cost-plus model, competition-oriented model, and demand-oriented model. Since each model an be converted to a set of constraints in point and interval forms, solving the pricing problem with the three groups of models requires an algorithm which can solve the problem with weighted constraints of intervals and points. So we have devised an algorithm named “Point Determination Algorithm”. From the rules that represents tile models, the constraints are extracted to be solvable by tile Point Determination Algorithm. A prototype KAPA (Knowledge Assisted pricing Advisor) is developed with this idea using the expert system environment UNIK - a tool developed by KAIST. According to the experiment with 76 items in comparison with 53 human pricing experts we confirmed that the KAPA can perform highly consistent with human experts. This implies KAPA system is applicable to pricing millions of items dynamically.

This study was conducted to evaluate the planar (rolling) shear strength of OSB (oriented strand board) panels and domestic plywood through 5 point bending test method in ASTM D2718 standard. The test specimens were prepared in parallel and perpendicular direction to major axis (along the length of panels) and tested up to failure, and failure modes were also examined. From the test results, rolling shear strength were found to be $1.32{\sim}1.94N/mm^2$ in parallel to major axis, and $1.46{\sim}1.99N/mm^2$ in perpendicular to major axis respectively. Little difference was found between parallel and perpendicular direction of rolling shear strength. There were no statistically significant differences in rolling shear strength between Canadian OSB and domestic plywood in the parallel direction, and between Chilean OSB and domestic plywood in the perpendicular direction. The shear failure was observed in all tested OSB panels, whereas shear failure, glue line delamination, and bending combined with shear failure were observed in the domestic plywood.

Purpose: The aim of this study was to analyze relationships between perfectionism, burnout, and emotional intelligence in APN and to identify the mediating effect of emotional intelligence on the relationship between perfectionism and burnout. Methods: A structured self-report questionnaire was used to measure perfectionism, burnout, and emotional intelligence. Data were collected from 121 APN working in five advanced general hospitals and two general hospitals. Data were analyzed using descriptive statistics, Independent t-test, One-way ANOVA, Mann-Whitney U test, Pearson correlation and Hierarchical multiple regression with the SPSS/WIN 22.0 program. Results: Mean scores for each variable were: perfectionism 3.57 (on a 5-point scale), burnout 3.32 (on a 7-point scale), and emotional intelligence 5.00 (on a 7-point scale). Self-oriented perfectionism had a positive correlation with burnout, as did socially prescribed perfectionism. Emotional intelligence was a significant variable reducing burnout, as it also had a reverse buffering effect on the relationship between self-oriented perfectionism and burnout. Explanatory power of the final model based on variables was 34%. Conclusion: The results of this study suggest a mediating direction regarding burnout by demonstrating that emotional intelligence plays a direct and reverse buffering role to self-oriented perfectionism, which can be used to reduce burnout in APN.

The object-oriented coding technique which is one of the coding methods in very low bit rate environment is suitable for videophone image sequence. The selection of source model affect image analysis. In this paper, an image analysis method for the object-oriented coding is presented. The process is composed of changed region detection andmotion estimateion. First, we use the standard deviation of frame difference as thrreshold to extract themoving area. If thesum of gray values in mask is greater than the threshold, the center pixel of the mask is regarded as moving region. After moving is detected in changed region by edge operator, observation point is determined from moving region. The motion is estimated by 6-parameter mapping method with determined observation point. The experimantal resutls show that the proposed method can significantly improve the image quality.

The starting point of this study was that the Orientalism reflected in the modern clothing is realized the different view by Western and Eastern. Based on this regard, this study semiotically analyse that clothing is creating the cultural values and signification and that the western designers are reproducing an ideology as orientalism being the western-oriented thought when expressing the Asian image in the modern clothing. The theoretical sides are based on the semiotic analyses of F. Saussure, C. Peirce, and R. Barthes. By the result observed through this study, the Orientalism reflected in the modern clothing designed by Western designers are discriminative image, mystic image, past-oriented image, natural image, and complex-eclectic image. The discriminative image is reproduced as a savage and uncivilized image. In addition, it regarded as a decorative and superficial image is expressed as if it is an uncharacterized and underdeveloped image in the modern clothing. The mystic image is reproduced as a romantic image to stimulate Westerners'curiosity. That is, Asian image is regarded as a dream and magical image rather than a scientific and rational image. The past-oriented image is expressed through restricting Asian positive image in Asian historical glory. The natural image differs from Western image based on science in the modern clothing. The modern clothing regards the natural image as a primitive and instinctive image. The complex-eclectic image is the pastish pattern through selecting and distributing heterogeneous materials in the modern clothing. This study critically analyzes the western-oriented thought of orientalism in the modern clothing. The results of the study imply that it is critical that we provide a new contact point for the East and the West in the context of our Asian values and traditions.

The purpose of this study is to look into the support activities of the 17th century spanish plays which had been taken in various paths in terms of responses of the then-public who had been enthusiastic about great plays and artworks. Such a phenomenon clearly appeared in the open-air theater 'corral' where 'Teatro nacional' was performed at that time. Therefore, this study tries to investigate the functional relation between the public's responses and the prosperity of then-plays from the concrete standpoint of Lope's public-oriented plays. Although Lope's plays basically include system-protection ideology, they are thoroughly based on the public's support and popularity. In short, at that time, Lope's dramatic reform and entailing remarkable hit and success were made possible through thorough compliance with the public's preference and thereby the public's absolute support and affection. The tendency of his public-oriented plays appears in two aspects. One is the common people persecuted and punishment of a wicked man of power. The typical plays in point are Lope's Perib??ez y el comendador de Oca?a and El mejor alcalde, el rey. Through the plays, the playwright Lope not only implemented praise of absolute monarch very effectively, but soothed the wounded heart of the common people who had suffered pains due to their unfair and lowly social status. In this way, his plays might give senses of reliefs and satisfaction to most viewers who identified with the common people in the plays. The other one is the decisive raise of status of an exemplary commoner, the subject matter which had been used by Lope as one of useful means to show the public-oriented tendency of his plays. The cases in point are Los Tellos de Meneses and its succeeding work Valor, fortuna y lealtad. The two-part work of Lope is about the hard journey, ups and downs, and ascent to the nobility of Tello, an exemplary and rich farmer, and hits young son Tello. Through the two-part play, Lope demonstrated how an exemplary and good-mannered commoner rose to the nobility and thereby gave vicarious satisfaction to the then-public and received a lot of praise from them. As mentioned earlier, through his public-oriented plays, Lope not only satisfied the public's desires and achieved his realistic goal of big success. Not all Lope's plays are public-oriented. Nevertheless, the popular success of 'Teatro nacional' made by Lope and his followers is based on the public's preference and the plays' dramatic responses to their desires, and the strategic elaboration to comfort the public suffering lot of pains in daily life.

A nonlinear Finite Element (FE) algorithm is proposed to analyze the Reinforced Concrete (RC) columns subjected to Cyclic Loading (CL), Cyclic Oriented Lateral Force and Axial Loading (COLFAL), Monotonic Loading (ML) or Oriented Pushover Force and Axial Loading (OPFAL) in any direction. In the proposed algorithm, the following parameters are considered: uniaxial behavior of concrete and steel elements, the pseudo-plastic hinge produced in the critical sections, and global behavior of RC columns. In the proposed numerical simulation, the column is discretized into two Macro-Elements (ME) located between the pseudo-plastic hinges at critical sections and the inflection point. The critical sections are discretized into Fixed Rectangular Finite Elements (FRFE) in general cases of CL, COLFAL or ML and are discretized into Variable Oblique Finite Elements (VOFE) in the particular cases of ML or OPFAL. For pushover particular case, a fairly fast converging and properly accurate nonlinear simulation method is proposed to assess the behavior of RC columns. The proposed algorithm has been validated by the results of tests carried out on full-scale RC columns.

Euler and Navier-Stokes flow analyses for helicopter rotor in hover were performed as low and high fidelity analysis models respectively for the future multidisciplinary design optimization(MDO). These design-oriented analyses possess several attributes such as variable complexity, sensitivity-computation capability and modularity which analysis models involved in MDO are recommended to provide with. To realize PC-based analyses for both fidelity models, reduction of flow domain was made by appling farfield boundary condition based on 3-dimensional point sink with simple momentum theory and also periodic boundary condition in the azimuthal direction. Correlations of thrust, torque and their sensitivities between low and high complexity models were tried to evaluate the applicability of these analysis models in MDO process. It was found that the low-fidelity Euler analysis model predicted inaccurate sensitivity derivatives at relatively high angle of attack.

This paper presents a newly proposed object-oriented finite element framework and its applications on dynamic analysis of plate girder bridge. The developed framework supports various types of finite elements, materials, constraints, loads, and solution methods. One major feature different from other object-oriented finite element programs is that static model and dynamic state can be easily read from or written to a file. In addition, the framework supports efficient DOF pattern handling for a node connecting elements with different DOF patterns, new multi-point constraint handling, and various scripting languages for easy use of the library. In order to show the applicability to dynamic analysis, dynamic moving load analysis on plate girder bridge is performed.
