This study tested the validity of a three-factor model of the centrality of visual product aesthetics developed by Bloch, Brunel, and Arnold (2003) and explored the relationships between the centrality of visual product aesthetics and the relevant constructs. It was hypothesized that the path relationships including innovativeness and consumer independent judgment making are relevant constructs of the centrality of visual product aesthetics. Data were gathered by surveying university students in the Seoul metropolitan area (using convenience sampling) and 322 questionnaires were used in the statistical analysis. Correlation analysis, factor analysis, and regression analysis were conducted to analyze the data. The findings show the validity of the three factors (value, acumen, and response intensity) of the centrality of visual product aesthetics. Tests of the hypothesized path show that innovativeness influences the centrality of visual product aesthetics both directly and indirectly through consumer independent judgment making. Innovativeness positively influenced consumer independent judgment making and the three factors of the centrality of visual product aesthetics, whereas consumer independent judgment negatively influences the response intensity factor of the centrality of visual product aesthetics. The implications of these findings and suggestions for future study are also discussed.

The market for counterfeit luxury fashion goods is proliferating across the globe. In an effort to provide some insight into this phenomenon, this study aimed to identify the antecedents of attitudes toward counterfeits of luxury fashion goods. As antecedents, counterfeit proneness and attitudes toward counterfeiting were considered. It was hypothesized that counterfeit proneness not only influences attitudes toward counterfeits of luxury fashion goods directly but also indirectly through attitudes toward counterfeiting. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred five questionnaires were used in the statistical analysis. SPSS was used for exploratory factor analysis, and AMOS was used for confirmatory factor analysis and path analysis. The results showed that all the fit statistics for the variable measures were quite acceptable. In addition, the overall fits of the hypothesized model suggest that the model fits the data well. Factor analysis revealed that counterfeit proneness and attitudes toward counterfeits of luxury fashion goods were uni-dimensional and that attitudes toward counterfeiting were two dimensional, which are 'normatively less susceptible' and 'value conscious'. Test of the hypothesized path showed that counterfeit proneness influences attitudes toward counterfeits of luxury fashion goods indirectly through the two factors of attitudes toward counterfeiting. The results suggest some implications for anti-counterfeit businesses.

The aim of this research was to track the appropriate path favorable to urban development when finding small streams which had been destroyed during the process of urbanization and restoring the streams to a natural flow. This research located the targeted streams in the urban area by using GIS, and designated 3 main factors in restoring small streams: altitude, the usage of land, and land prices. After analyzing the possibilities and outcomes of each factor, the study found the most suitable remedy reflecting those 3 factors. Since there are various effects on stream restoration, based on these 3 factors, the study found and used the most viable factor in accordance with its importance. Using this template, the study developed a method to track the most appropriate restoration path. The study results will contribute to finding, and the restoration of disappeared streams for making more pleasant urban life and an environmentally-friendly city.

This study tried to test hypotheses, using path analysis, whether the implementation factors of TQM have influences to organization performance through achieving the managerial goals of production, or not. This is an attempt to perform comprehensive analysis instead of using the simple correlation approach between the implementation factors and performances. In order to perform the empirical test, this study has surveyed 98 firms which acquired the ISO authentication and analyzed the data using the path analysis of AMOS. After testing the hypotheses of this study, the cause factor, i.e. TQM implementation factor, has effective influences to the goals of production system, and, also, the goals have a significant influence to managerial performance. Therefore, this study concludes that the implementation factors of TQM have significant effects on the managerial performance.

In this paper, we proposes a sensor node positioning algorithm that utilizes the geo-spatial elements and considers the factors to represent the propagation loss generated by the various obstacles in the urban wireless environments. First, we measures the propagation loss about the radio frequencies in major road of the urban, and defines the correlation between the measured loss and the environment information for the road and its surrounding get from Urban GIS. Secondly, through the utilization of the loss-environment correlation, we describes the detailed instruction for requiring the radio coverage decision and deploy system implementation for the wireless sensor node in urban. By the consideration of interference factor by the building and the linear structure of road, we can evaluate the path loss below 5dB RMS error. And, we proposes the way to revise the sensor node deployment based on the corelation and the measured path loss.

In recent years, with the development of devices to collect multimedia data such as small CMOS camera sensor and micro phone, studies on wireless multimedia sensor network technologies and their applications that extend the existing wireless sensor network technologies have been actively done. In such applications, various basic schemes such as the processing, storage, and transmission of multimedia data are required. Especially, a security for real world environments is essential. In this paper, in order to defend the sniffing attack in various hacking techniques, we propose a multipath routing scheme for physically avoiding the data transmission path from the risk factors. Our proposed scheme establishes the DEFCON of the sensor nodes that are geographically close to risk factors and the priorities according to the importance of the data. Our proposed scheme performs risk factor detour multipath routing through a safe path considering the DEFCON and data priority. Our experimental results show that although our proposed scheme takes the transmission delay time by about 5% over the existing scheme, it reduces the eavesdropping rate that can attack and intercept data by the risk factor by about 18%.

For an complete image composition to be stitched on several mosaic images, tracing displacement of direction and distance between successive images are important parameters. The input image is modeled by using a general second order two-dimensional Taylor-series and then converting it to a $3{\times}3$ correlation block and storing the data. A moving factor and coordinate is calculated by comparing the continuous correlation blocks. The experimentation result has a success rate of 85% for moving path tracing as continuous images are moved to 10% of image central position.

In this paper, Hopfield & Tank model-like artificial neural network structure is proposed, which can be used for the optimal path planning problems such as the unit commitment problems or the maintenance scheduling problems which have been solved by the dynamic programming method or the branch and bound method. To construct the structure of the neural network, an energy function is defined, of which the global minimum means the optimal path of the problem. To avoid falling into one of the local minima during the optimization process, the simulated annealing method is applied via making the slope of the sigmoid transfer functions steeper gradually while the process progresses. As a result, computer(IBM 386-AT 34MHz) simulations can finish the optimal unit commitment problem with 10 power units and 24 hour periods (1 hour factor) in 5 minites. Furthermore, if the full parallel neural network hardware is contructed, the optimization time will be reduced remarkably.

In this paper, the mathematical model on crosstalk effect between acoustic noise sources is presented. Based on this model, a theoretical value to quantitate crosstalk effect of sources can be defined on the authority of reverberation property of surrounding which sources are located, relative magnitudes of sources and phase deference between acoustic wave transferred from all of sources. In order to verify crosstalk effect factor, experiments are made for two cases, weak and strong crosstalk effect condition, by using toro representative transfer path analysis(TPA) methods.

Binary CDMA(B-CDMA) is a new modulation scheme that employs a constant envelope modulation scheme By quantizing the envelope of multi-codes CDMA signal into a small number of levels, the B-CDMA can reduce the peak-to-average power ratio, while preserving the advantages of CDMA signaling such as the soft capacity and robustness to interference. In this paper, we analyze the performance of B-CDMA systems in multi-path channel assuming that the spreading factor is not too small. Finally, the analytic results are verified by computer simulation.
