The present study examines whether consumers' perception of waiting time and their behavioral intentions are influenced by the presence of background music in an online shopping environment. In particular, this study aims to explain the underlying mechanism for the effects of background music on consumers' perceived wait and behavioral intentions toward the online retailer by proposing the mediating role of emotions drawing on the Stimulus-Organism-Response (S-O-R) framework. A lab experiment was employed to test the hypotheses. A total of 102 college students were used for data analyses. Results show that the presence of music has a significant impact on participants' emotions, perceived waiting time, and approach behavior. Moreover, the findings show that pleasure and the perceived waiting time serve as mediators in the relationship between the presence of music and approach behavior. Implications of the model for theory, practice, and further research are discussed.

Recently, as the alternatives to preserve environment such as effective usage of wastes or unusable resources are drawing attentions, researches and measures for the two tasks, which are reuse of waste wood and development of eco-friendly materials, are being examined and established in various fields. However, they are still insufficient. Therefore, in this study, for the efficient application of waste woods and eco-friendly effects, mortar was produced using sawdust as the waste wood and mineral material cement for combination, in order to produce inorganic boards using waste woods. which were made when sawing. This study attempted to suggest a basic material about the physical properties of mortar, which used waste woods, after examining the features of wood mixture rate, water-cement rate, consolation according to the mixture rate of the setting accelerator, specific gravity, compression intensity, and bending intensity as experiment factors.

A variational formulation and the associated finite elemet equations have been derived for general three-dimensional deformation of a planar anisotropic rigid-plastic sheet metal which obeys the strain-rate potential proposed by BARLAT et al [13]. By using the natural convected coordinate system, the effect of geometric change and the rotation of planar anisotropic axes are considered efficiently. In order to check the validity of present formulation, a cylindrical cup and a square cup deep drawing test was modeled. good agreement was found between the FE simulation and the experiment. The results have shown that the present formulation for planar anisotropic deformation can be efficiently applied to the analysis of sheet metal working processes for planar anisotropic nonferrous metals.

An optimal design procedure is proposed to effectively reduce the torque ripple by optimizing the rotor pole shape of the spoke type IPMSM with concentrated winding. The procedure is composed of two steps. In step I, the steepest descent method (SDM) is used with only two design variables to rapidly approach the optimal shape. From the near optimal rotor shape as a result of the step I, the design variables are reselected and the drawing spline curves are utilized to explain more complex shape with the Kriging model in step II. By using an optimal design procedure, we show that the optimized rotor pole shape of the spoke type IPMSM effectively reduces the torque ripple while still maintaining the average torque.

This paper presents the control X-Y table being the precise movement by point-to-point in the x-y plane. The dual modulus technique is used for our system to control the frequency of pulse supplied to the motors. Such technique is used to stop motor of both axes accurately as the desired target point in the same period. Both motors are stepping motor. To Improve steps per revolution, we employ ministep form to drive motors. In system, personal computer, using parallel port, is used for computing algorithm in open-loop form to control motors. In experiment, our system applies on the X-Y table for drawing to test system performance.

This study analyzed the mechanical behavior of lithium-ion battery pouch material and predicted its formability. A homogenization method was used to evaluate the physical properties of the pouch, and a new hardening model was developed. The yield function for the plastic model was optimized, and the anisotropic property was determined. Also, the forming limits were measured and predicted using the M-K forming limit diagram. Finally, a square cup drawing experiment confirmed the accuracy of the measured mechanical properties and the formability calculation.

Due to the differences between and distinct consumer perceptions of domestic and cross-border e-commerce (CBEC), e-consumer misconduct, which we call "cunning behavior," has emerged. This study examines cunning behavior in CBEC and compares e-consumer perceptions about environmental factors and their own personal traits using a vignette experiment and survey. The vignettes of this study were developed for three situations: illegal, deviant, and unethical behavior. Drawing on vignettes, we collected survey data and then examined the research model using the analysis of moment structure statistical tool. The results show that perceived benefit and past experience with CBEC are strong triggers for cunning behavior, while the ability to exercise self-control restrains this behavior. This study provides an understanding of why cunning behavior occurs in the CBEC context and describes different cunning behavior types.

This study was performed to survey the achievements in problem solving by the inquiring experiment, which was done by the superior group in the traditional cocepts-centered written tests. The purpose of this study was to identify characteristics of inquiring experimental assessment by analyzing differences between concepts-centered written and inquiring experimental tests. The subjects of this study was 211 applicants. They are the superior group of the 9th grade students, and score in the top 1% of total achievements percentage in school. They also have passed the primary entrance examination. The inquiring experimental test was developed according to the curriculum in school, and is composed of 5 subcategories: problem-perception and formulating hypothesis, designing an experiment, carring out an experiment, recording data and drawing conculsion, and generalizing conculsions and communicaton. The checklists of each subcategory were made and testing methods were divided into observation and report. The major results of this study are as follows: 1. The achievements in each subcategory of inquiring experimental performance were very low in the superior group who took the concepts-centered written tests. 2. The results of factor and correlation analyses in this study confirmed the abilities measured by inquiring experimental assessment differed from abilities measured by existing tests. These results indicated that even students who achieved high in scientific knowledge, these abilities were not automatically transformed inquiry process which many other abilities were integrated into. Therefore, problem solving ability requires integrated abilities which are fostered by inquiring experimental tasks. This suggests that new instrument for assessment must be developed to measure integrating ability especially where scientifically gifted students are selected, or where entrance examinations to the science schools are administered.

The purpose of this study is to investigate the effect of tone-on-tone coloration on the visual images of traditional Korean dress. The materials in the experiment developed for this study were made up of various stimuli and the response scales for each stimulus. The stimuli were 48 color pictures with various combination of colors, in which the tones of jackets and skirts were manipulated by computer drawing. 24 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate each image. The subjects were 576 female students in Jinju City. This experiment was based on the $3{\times}4{\times}4$ factorial designs: color (red, yellow and green), jacket tone (vivid, light, dull and dark) and skirt tone (vivid, light, dull and dark). The results of the study can be summarized as follows; Impression factor of the stimuli consisted of the 5 different dimensions - youthfullness and activity, attractiveness, gracefullness, visibility, and tenderness. The colors and the tone of jackets and skirts used in this experiment influenced 5 impression dimension by interaction of two valuables or working independently. Yellow and green with vivid or light tone had an effect on the formation of youth and activity image, and dark-light combination had an effect on the formation of attractiveness image. In case of green color, light tone of a jacket and vivid or dull tone of a skirt affected gracefulness, while yellow has no impact on visibility image regardless of skirt tone. Red and yellow with vivid or light tone were a factor to decide tenderness.
