  • Extended Drude model has been used to obtain information of correlations from measured optical spectra of strongly correlated electron systems. The optical self-energy can be defined by the extended Drude model formalism. One can extract the optical self-energy and the electron-boson spectral density function from measured reflectance spectra using a well-developed usual process, which is consistent with several steps including the extended Drude model and generalized Allen's formulas. Here we used a reverse process of the usual process to investigate the extended Drude analysis when an additional low-energy interband transition is included. We considered two typical electron-boson spectral density model functions for two different (normal and d-wave superconducting) material states. Our results show that the low-energy interband transition might give significant effects on the electron-boson spectral density function obtained using the usual process. However, we expect that the low-energy interband transition can be removed from measured spectra in a proper way if the transition is well-defined or well-known.

  • The reinforced concrete (RC) structures usually suffer large residual displacements under strong motions. The large residual displacements may substantially reduce the anti-seismic capacity of structures during the aftershock and increase the difficulty and cost of structural repair after an earthquake. To reduce the adverse residual displacement, several self-centering energy dissipation braces (SCEBs) have been proposed to be installed to the RC structures. To investigate the seismic responses of the RC structures with SCEBs under the earthquake excitation, an extended Bouc-Wen model with degradation and self-centering effects is developed in this study. The extended model realized by MATLAB/Simulink program is able to capture the hysteretic characteristics of the RC structures with SCEBs, such as the energy dissipation and the degradation, especially the self-centering effect. The predicted hysteretic behavior of the RC structures with SCEBs based on the extended model, which used the unscented Kalman filter (UKF) for parameter identification, is compared with the experimental results. Comparison results show that the predicted hysteretic curves can be in good agreement with the experimental results. The nonlinear dynamic analyses using the extended model are then carried out to explore the seismic performance of the RC structures with SCEBs. The analysis results demonstrate that the SCEB can effectively reduce the residual displacements of the RC structures, but slightly increase the acceleration.

  • In Meditation II, Descartes questions "sed quid igitur sum" ("But what then am I?"). To this question to rule our essence, A. Clark insists that "We are soft selves". The idea by Clark is a spontaneous conclusion of the extended mind theory stating that cognitive process, cognitive state, and self may be extended over biological organisms. However, it seems that it is difficult for the extended self to have the qualifications as a moral agent. There have been disputes about expandability of cognitive process and cognitive state, but there have not been many disputes about the possibility of accountability of behavior by the extended self. First of all, in this thesis, it will be revealed that the extended self through the analysis of metaphorical theories and the ontological essence of agent and behavior by G. Lakoff and M. Johnson is just metaphorical rhetoric, which is not suitable for rational comprehension of ontological essence of agent and behavior. Moreover, the analysis of problem about artificial moral agent (AMA) proposes the "Strong First-person Viewpoint" as a requirement of the agent. Finally, the concept of extended self will be shown to be unsuitable for theoretical explanation of us, and the concept of human person will be proposed as an alternative solution.

  • As Chinese luxury consumption is rapidly expanding and dominant in global luxury market, it becomes very critical to understand Chinese consumers' luxury consumption pattern. Under this circumstance, this study empirically tested the impacts of Chinese consumers' perceived service quality of luxury stores and extended self of luxury on luxury purchasing intention. The result of this study is as follows. First of all, Chinese consumer' perceived service quality of luxury store and extended self of luxury have positive impacts on luxury purchasing intention. However, Chinese consumer' extended self of luxury has partial interaction impact on luxury purchasing intention. From the results, to promote Chinese consumers' luxury consumption, marketers must improve the service quality of luxury store and extended self of luxury. This research not only enrich theoretical knowledge about Chinese consumers' luxury purchase behavior, but also assist marketer to develop luxury marketing strategies in China.

  • Purpose - This study presents the relationships between parent brand-self image congruence, parent brand -functional congruity, perceived fit between parent brand and extension product, and consumer's attitude toward extension product using the structural equation model. As for preceding concepts having a direct effect on consumer's attitude toward brand extension, the study focuses on parent brand-self image congruence and parent brand-functional congruity. It also looks at the effect of parent brand-self image congruence and parent brand-functional congruity on the consumer's attitude toward extension product and identifies if the perceived fit between parent brand and extension product is a concept playing a mediating role between parent brand-self image congruence or parent brand-functional congruity and consumer's attitude toward brand extension product. Research design, data, and Methodology - SPSS for Windows 18.0 and AMOS 18.0 were used for data analysis. Then, the Cronbach's α coefficient was obtained using SPSS for Windows 18.0 to measure reliability. In addition, the convergence and discriminative measures of the measured items were statistically verified using AMOS 18.0. Finally, we have validated a path model and a parameter model in which brand personality-self-matched attitude toward brand extension. Results - Studies have shown that the impact of parent brand-self image consistency and parent brand-functional consistency on the attitude of extended products was positive. Perceived fit between parent brand and extension products has been shown to play a role of intermediary between parent brand-self image congruence and consumer attitudes to extended products. However, perceived fit between parent brand and extension products did not play a role as intermediary between the parent brand-functional congruity and the attitude toward the extended product. Finally, in relation to the causal relationship between parent brand-congruity (self image/functionality) and attitudes to extended products. The effect of parent brand-functional coherency on attitudes toward extended products was found to be greater in groups with higher involvement than in those with lower involvement. Conclusions - Although few studies have been done on what variables mediated when parent brand-self image consistency and parent brand-functional coherency affect consumer attitude, this paper is significant in finding whether perceived fitness between the parent brand-congruity and the extension product is mediated.

  • Purpose - This study attempted to identify any influencing relationships, between the antecedent variables and the members' innovative work behavior, which were expected to influence organizational performance based on the extended theory of planned behavior (ETPB). Research design, data, and methodology - The survey was conducted on SMEs in Seoul and its metropolitan area. A total of 158 copies of effective questionnaires were used and were analyzed through correlation analysis, regression analysis, and multiple regression. Results - Self-efficacy, value, intrinsic motivation, and self-enhancing bias have been found to have a positive relationship with innovative work behavior. In addition, transformational leadership was found to moderate the existence of a statistically significant negative influence between value, intrinsic motivation, and innovative work behavior. Conclusions - The results suggest that leaders will be successful in winning members' trust through conducting their behaviors in accordance with the applicable ethical and moral standards and through their fair, transparent, and legitimate management practices with an attitude of 'taking the initiative and setting an example', and this will help solve such problems.

  • In the original incremental Extended Horizon Control, the control inputs are computed recursively each step in the prediction horizon. But in this paper, we propose another incremental Extended Horizon Self-tuning Control version in which control inputs can be computed directly in any time interval. The effectiveness of this algorithm in a variable time delay or load disturbances environment is demonstrated by computer simulation. The controlled plant is a nonminimum phase system.

  • In this paper the PID-B self-tuner[1] is extended to allow a less abrupt response to set point or plant parameter changes and to control a nonminimum phase plant. The proposed extended PID/ST derived from the direct pole-placement PID/ST is obtained with the Bezout identity as the underlying design method. And its control gains are normalized by the integral control gain. Although the integral control gain is normalized to 1 in our scheme, the so-called "set point and derivative kick" can be avoided sufficiently by normalizing the measurement vector and set point.
