Vintage fashion is a lot influenced by colors because an emotion is transmitted via images of "old feeling", "worn-out feeling" and "faded feeling" etc. Colors are visual sensation occurring at a time when lights stimulate an eye, which is a representative factor which humans first perceive when they touch objects. And colors in clothing function as a critical element which indicates an individual's impression and character as well as aesthetic sensation. In this study, I examined on the theoretical consideration and aesthetic characteristics via the previous literature on vintage fashion and colors. As an empirical study, I investigated on the colors of vintage fashion appearing in Pr$\hat{e}$t-$\grave{a}$-porter Collections, Paris from Spring/Summer, 2003 to Fall/Winter 2008. As a way for study, I investigated into the total 197 vintage fashion photos and calculated their RGB values by using photoshop. And I converted the values of the colors extracted into H V/C values by using Munsell Conversion Version 9.0.6 and analyzed on Munsell System of 10 Color Notation and the PCCS colors, classifying a color scheme by visual sensation measurement. The result of analyzing on the concept of vintage fashion and its color characteristics is as follows; Vintage fashion made an appearance the most in 2003 and 2004 and its colors appeared a lot in Y, YR, R and PB lines. Color tone concentrated on black and white, achromatic color and low chroma colors in a grayish line, chromatic color. Thus, the study found that colors suitable for a "worn-out", "faded" and "old" image are properly reflected in vintage fashion rather than a clear and bright background. In a color scheme, I found contrast color and same color appearing a lot, which gave an unharmonious feeling and a smack of the country. The study reveals that the color characteristic of vintage fashion is relatively diverse and complex in color, color tone or shade and color scheme, which shows a color trend which reflects a non-constructive and complex coordination characteristic instead of a standardized simple and clear image.

According to the capacity design concept underlying current steel seimsic provisions, the braces in concentrically braced frames should dissipate seismic energy through cyclic tension yielding and compression buckling. On the other hand, the beams and the columns in the braced bay should remain elastic for gravity load actions and additional column axial forces resulting from the brace buckling and yielding. However, due to the difficulty in accumulating the yielding and buckling-induced column forces from different stories, empirical and often conservative approaches have been used in design practice. Recently a totally different approach was proposed by Cho, Lee, and Kim (2011) for the prediction of column axial forces in inverted V-braced frames by explicitly considering brace buckling. The idea proposed in their study is extended to X-braced seismic frames which have structural member configurations and load transfer mechanism different from those of inverted V-braced frames. Especially, a more efficient rule is proposed in combining multi-mode effects on the column axial forces by using the modal-mass based weighting factor. The four methods proposed in this study are evaluated based on extensive inelastic dynamic analysis results.

This paper evaluates the effects of privatization and deregulation on the firm-specific efficiency and total factor productivity (TFP) growth in the Korean and Japanese railways. Using a stochastic frontier approach and a generalized translog functional form, the paper specifies the equation system consisting of a multiproduct variable cost function and input share equations which is estimated with Zellner's iterative seemingly unrelated regression and the corrected least squares method. The Korean and Japanese railway firms are assumed to produce three outputs (Shinkansen passenger-kilometers, incumbent railway passenger-kilometers, ton-kilometers of freight) using three input factors (labor, fuel, maintenance and rolling stock). A monetary value of the ways and fixed installations held by the railroad firm is also included as a quasi-fixed input. The empirical results indicate that the average estimate of cost inefficiency is 2.57% for the total sample and on the average, JNR and JR Kyushu are found to be worst efficient while the most efficient railway firm in the sample is JR West. Also the cost efficiency levels of seven JRs have been improved after the reform and privatization of JNR. The findings also indicate that TFP growth of the privately-owned JRs are higher than those of the government-owned KNR and JNR. Three-island JRs and JR Freight have slightly higher TFP growth than Honshu JRs as well. Thus, the results suggest that managerial autonomy and increased competition via deregulation have improved efficiency and TFP growth.

The aim of this study is to analyze the effects of DVR(Driving Video Recorder) operation on decreasing the number of traffic accidents, the cost of traffic accident claim, and the behavioral change in drivers' driving. The data for this research are obtained from taxi drivers in Busan. For this, Structural Equation Model and two-way ANOVA are employed for empirical analysis. Overall results of this study show that the number of traffic accidents of 4 taxi corporations in Busan has decreased by average 32.7 percent after using DVRs. In addition, as to the cost of taxi accident claims, it is expected that the DVR operation has a considerable effect on economic benefits of taxi corporations. Moreover, this study could make clear the difference in behaviors between DVR users and non-users, and discriminate the positive and negative impacts of the DVR operation on the drivers' driving behavior. The study quantitatively examined the indirect impact of 'attitude', 'subject norm' and 'behavioral control' factors on planned 'behavior', and the direct impact of 'behavioral control' factor on the planned 'behavior'. This study suggests that they should add the video recoding function of DVRs when operation recorder(blackbox for the car) is obligatorily set up on cars for business by traffic security law.

This study investigates the effects of product strategies and CEO characteristics on the growth of venture firms. These factors are related with strategic behaviors and managerial capabilities of small and dynamic firms. According to empirical results of FGLS regression with the data of the Korean venture firms, both product strategies and CEO characteristics have significant effects on firm growth and additionally explanatory powers. In general, the growth rates of venture firms tend to increase with the level of product's diversity and marketing-enhancing strategy, but decrease with the degree of product's innovation-enhancing strategy. The growth rates are higher when CEO is non-founder and has sufficient experience related to current business, and CEO's career development is focused on general management area. The effects of product strategies and CEO characteristics are moderated by the firm-internal factor such as organizational growth stage. The positive effects of some product strategies (e.g. marketing-enhancing strategy) and CEO characteristics(e.g. career focused on general management) become stronger for firms operating in the stage of start-up or initial growth, while their effects become negative or insignificant for firms operating in the mature or declining stage in which the negative effect of innovation-enhancing strategy does not exist.

The importance of securing water resources and their efficient management has attracted more attention recently due to water deficit. In water budget analysis, however, evapotranspiration (${\lambda}E$) has been approximated as the residual in the water balance equation or estimated from empirical equations and assumptions. To minimize the uncertainties in these estimates, it is necessary to directly measure ${\lambda}E$. In this study, using the eddy covariance technique, we have measured ${\lambda}E$ in a mixed forest in the Seolmacheon catchment in Korea from September 2007 to December 2008. During the growing season (May - July), ${\lambda}E$ in this mixed forest averaged about 2.2 mm $d^{-1}$, whereas it was on average 0.5 mm $d^{-1}$ during the non-growing season in winter. The annual total ${\lambda}E$ in 2008 was 581 mm $y^{-1}$, which is about 1/3 of the annual precipitation of 1997 mm. Despite the differences in the amount and frequency of precipitation, the accumulated ${\lambda}E$ during the overlapping period (i.e., September to December) for 2007 and 2008 was both ${\sim}$ 110 mm, showing virtually no difference. The omega factor, which is a measure of decoupling between forest and the atmosphere, was on average 0.5, indicating that the contributions of equilibrium ${\lambda}E$ and imposed ${\lambda}E$ to the total ${\lambda}E$ were about the same. The results suggest that ${\lambda}E$in this mixed forest was controlled by various factors such as net radiation, vapor pressure deficit, and canopy conductance. In this study, based on the direct measurements of ${\lambda}E$, we have quantified the relative contribution of ${\lambda}E$in the water balance of a mixed forest in the Seolmacheon catchment. In combination with runoff data, the information on ${\lambda}E$ would greatly enhance the reliability of water budget analysis in this catchment.

In this study, We have newly introduced consumption emotions and switching cost, as a means of managing existing customers, to examine influencing determinants in repurchase intentions along with customer satisfaction and service quality which have been important determinants in previous researches on repurchase intentions. To test them empirically, data from corporate customers of a bank in Korea and corporate banking related bankers are collected and analyzed by LISREL 8.12.. The result of this study can be summed up as follows. First, the most important determinant factor in repurchase intentions is customer satisfaction. Second, it is desirable to measure service quality not only in terms of process service quality, a process of service delivery to customers, but also outcome service quality, what customers receive from services or from service providers. Third, positive consumption emotions have positive influence upon customer satisfaction, negative consumption emotions have negative influence upon customer satisfaction and repurchase intentions. Fourth, switching cost, even though small in its influence, has been proved to be antecedent in repurchase intentions along with customer satisfaction and negative consumption emotions. After research, as precedents in customers' repurchase intentions, customer satisfaction and process service quality have exercised the biggest influences. Also, positive consumption emotions, negative consumption emotions, outcome service quality and switching cost can be used as determinants in predicting corporate customers' repurchase intentions.

This study explores the effect that unresearched organizational conduct has on employee engagement (job immersion) as a cause variable and the results from it. Major results identified in an empirical analysis are as follows. First, the main causes of organizational citizenship behavior (such as altruism, conscientious behavior, moral behavior, participatory behavior, and fair play) are shown to not affect job immersion. In other words, conscientious, participatory, and fair behavior affects job immersion, with participatory behavior having the greatest impact. Second, employees' concentration in an organization was only affected by participatory behavior and fair play behavior from among the factors of organizational citizenship behavior, only more so. That is, it has been shown that some of the causes of organizational citizenship behavior, including participatory behavior and fair play behavior, affect employee inter-behavior, and some of them are more influential than others. Third, the only factor that influences the intention to switch jobs among the organizational citizenship behavior is participatory behavior. In other words, altruism, conscientiousness, politeness, and fair play behavior do not affect the way people move from job to job. Participation in organizational citizenship behavior and fair play may affect employee inter-behavior, and the more influential participatory behavior may also affect the intention to relocate.

For the empirical analysis in this study, 335 cabin crews from large airline companies and budget airlines were interviewed using self-reporting questionnaires. The data was analyzed using the SPSS 23.0 and AMOS 23.0. First, of the organizational culture types, the relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were found to have negative impacts on job stress. Second, the innovation-oriented organizational culture, relationship-oriented culture, and hierarchy-oriented culture were found to have positive impacts on empowerment. Third, empowerment was found to have a negative impact on job stress. Fourth, as for the mediating effect of empowerment, the innovation-oriented culture, relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were verified to be all significantly mediated by empowerment in their relationship with job stress. As a result, it was shown that cabin crews of airline companies found their work more fun, interesting, and valuable in an organizational structure that was more oriented toward flexibility, rather than the hierarchical, task-oriented cultures that are more focused on control and order. It was also found that empowerment was a mediating factor in the relationship between organizational culture and job stress.

Most research on web site design has focused on technological factors, while visual aesthetic factors have been considered less important. In contrast, this study focuses on visual aesthetic factors in web site design. Findings of this study can be summarized as follows : (1) The result of SPSS-factor analysis shows that there are 3 distinct factors, 'classical aesthetics', 'expressive aesthetics', and 'usability' 'Classical aesthetics' and 'expressive aesthetics' can be described by visual aesthetic design, 'Visual aesthetic design' can be distinguished from 'usability'. This conceptual confusion relating to 'usability' and 'visual aesthetic design' can be clarified by these findings. (2) As a result of multiple regression analyses, 'classical aesthetics', 'expressive aesthetics', and 'usability' have a positive influence on 'interactivity' and 'web site evaluation'. This research clarifies the concepts of 'expectations' of Grier [18] and 'engagement' of Rosen and Purinton [33] as the 'interactivity' between users and web sites. Furthermore, this research suggests a valid model with high $R^2$(interactivity, 48% : web site evaluation, 68%). (3) Empirical tests show that the differences among users in 'entry point' are related to the characteristics of web sites and the personal characteristics of users. The differences among users in terms of 'scanning time' are closely related to the attitudes and evaluation tendencies of users with respect to web sites. These findings could contribute to the 'search phase' of the Faraday model [16], enabling it to be more precise and extensible. The managerial implication of this study is that customers' preferences regarding web site designs are differences, as their preferences are based on their individual characteristics. Therefore, marketing managers should consider promotional tools on web sites that are relevant to the target market. An optimal strategy for web design could be a carefully-selected combination of factors that are relevant to the 'interactivity' and 'evaluation' of web sites. Additionally, if marketing managers want to attract more favorable attitudes and more affirmative evaluations from users, web sites should be designed so that they are understood more quickly by users. finally, this study suggests that 'good design' for web sites depends on understanding how to attain the appropriate balance between 'classical aesthetics' and 'expressive aesthetics', based on the target customer.
