Purpose: This study aims to explore how consumers respond to the immoral actions of a CEO. More specifically, this research focuses on the moral reasoning processes used by consumers in order to maintain support for the CEO despite the immoral action. In addition, this research suggests that support for the CEO would improve product purchase intention. Research design, data, and methodology: To test the hypotheses presented, an online research company was hired and online survey was conducted with adult participants. Online research company sent an email to the potential subjects asking their participation in an online survey. Subjects were able to participate in the online survey by clicking a link to the survey. When the participants clicked the link, they were instructed to read a fictitious newspaper article on a CEO's immoral action. And then, they were asked to answer several questions online. Responses were obtained from 336 adults participants and data were analyzed using SPSS Hayes Macro for a moderation effect and AMOS for a structural equation model. Result: Moral reasoning processes were divided into moral decoupling and moral rationalization and analyzed to determine their influence on product purchase. Also in this study, we suggest the public self-consciousness of consumers as an antecedent of moral reasoning processes, and argue that consumers with high public self-consciousness are more likely to engage in moral decoupling than moral rationalization. Conclusions: Our results showed that moral decoupling and moral rationalization improved the consumer's perception of corporate ethicality, which increased product purchase intention. In addition, consumers with high public self-consciousness were more likely to engage in moral decoupling than in moral rationalization. In addition, this research suggested that severity of the scandal would moderate the impact of public self-consciousness on moral decoupling. However, this hypothesis was not supported statistically since most participants perceived the scandal to be a highly severe incident, that may lead to an insignificant interaction effect between severity of the scandal and public self-consciousness. This research expands the scope of available research on corporate ethics and consumer responses to negative information involving celebrities and provides practical implications for corporate crisis management.

A simple technique to decouple the modal equations of motion of a linear nonclassically damped system is to neglect the off-diagonal elements of the modal damping matrix. This is called the decoupling approximation. It has generally been conceived that smallness of off-diagonal elements relative to the diagonal ones would validate its use. In this study, the relationship between elements of the modal damping matrix and the error arising from the decoupling approximation is explored. It is shown that the enhanced diagonal dominance of the modal damping matrix need not diminish the error. In fact, the error may even increase. Moreover, the error is found to be strongly dependent on the exitation. Therefore, within the practical range of engineering applications, diagonal dominance of the modal damping matrix would not be sufficient to supress the effect of modal coupling.

Simultaneous Switching Noise (SSN) propagated through parallel power and ground planes in high-speed multilayer printed circuit boards (PCBs) causes malfunction of both digital and analog circuits. To reduce SSN, decoupling capacitors are generally used in the PCBs. In this paper, we improve the equivalent circuit model of decoupling capacitor in high-frequency range to analyze the effect of SSN reduction accurately. The analysis is performed by the microwave and RF design system (MDS) method and the finite difference time domain (FDTD) method. We compared the results by the ideal capacitor model with those by the proposed model.

The iron and steel industry is a manufacturing industry with the largest greenhouse gases emissions and has a great ripple effect on the national economy as a core material industry. This study internationally compared the decoupling patterns of greenhouse gases emissions in the iron and steel industry from 1990 to 2019, focusing on Korea, Japan, and Germany. In particular, unlike previous studies that considered only fuel combustion emissions, this study considered all fuel combustion emissions, industrial process emissions, and indirect emissions from the use of electricity and heat. As a result of the analysis, Korea is interpreted as expansive coupling, Japan as decoupling, and Germany as unclear. Therefore, the decoupling path that the Korean iron and steel industry should take should not be in Germany, but in the form of seeking a decoupling method similar to Japan or more effective than Japan. In addition, this study considered the characteristics of the iron and steel industry as much as possible and presented the causes of the decoupling analysis results and implications for the Korean iron and steel industry through comparison with Japan and Germany. In particular, four factors were suggested as factors which has promoted decoupling in Japan: high value-added of Japanese iron and steel products, development of energy efficiency technology in the Japanese iron and steel industry, strategic M&A of the Japanese iron and steel industry, and maintaining competitiveness according to the closed distribution structure of Japanese iron and steel products. The Korean iron and steel industry should also use the case of Japan as a benchmark to further increase added value through quality uprade and product diversification of iron and steel products, while at the same time making efforts to fundamentally reduce greenhouse gas emissions through the development of new technologies.

Automotive inverters may require current sensors for motor torque control, especially, in applications of hybrid electric vehicles or fuel cell vehicles. In this paper, to achieve a compact, integrated and low cost current sensor, a hall current sensor without magnetic core is introduced for integrating an automotive inverter. The compactness of the current sensor is possible by using integrated magnetic concentrators based on the Hall effect. Magnetic fields caused by three-phase currents are analyzed and a magnetic shield design is proposed for decoupling the cross-coupled field. It offers galvanic isolation, wide bandwidth (>100kHz), and accuracy(< 1%). Using 2D FEM analysis, its performance is demonstrated with design parameters at a U-shaped magnetic shield. The proposed coreless current sensor is tested with rated current to validate the linearity and accuracy.

In general, a power decoupling method using electrolytic capacitor is used to solve a problem that appears 120[Hz] ripple of grid at the PV module output. But electrolytic capacitor has a effect on the short lifetime and low reliability of PV system. Therefore, studies which replace the large electrolytic capacitor with small film capacitor have been researched in resent years. This paper proposes flyback inverter which can be replaced with film capacitor by connecting the circuit implementing zero voltage switching in PV side. The proposed system is validated by PSIM simulation.

In this paper, we study a Lotka-Volterra type simple food chain model. We investigate the positive coexistence of the steady states to the model and give some results for the extinction of species under certain assumptions which can be interpreted as Domino effect and Biological control. The methods of a decoupling operator and the fixed point index theory on a positive cone are used as well as the comparison argument. Numerical evidences for our results also are provided.
