In this study, we used 170 copies of the 190 questionnaires from March 18 to April 20, 2018, except for 20 that can't be used as statistical value. The purpose of this study is to analyze the relationship between organizational entrepreneurship and social capital, organizational performance, and the relationship between entrepreneurship and social capital. The main implications of this study are as follows. First, the entrepreneurship of the executives recognized by the organization members has a positive influence on the social capital in the organization. In other words, the higher the entrepreneurship of management, the higher the social capital in the organization. Second, the effect of the entrepreneurship of the management on the organizational performance is shown to have a statistically significant positive effect. In other words, the entrepreneurship of management was a key factor in achieving organizational performance. Third, social capital in the organization has a statistically significant effect on organizational performance. In order to improve organizational performance, it is necessary to systematically improve and reinforce entrepreneurship and social capital in management. On the other hand, it is considered that the executives' entrepreneurial spirit consistent with the characteristics of the company type, management environment, and organizational members should be continuously demonstrated, and the implementation plan for the social capital in the organization should be developed. Therefore, high quality organizational performance for corporate sustainability management emphasized the importance of executive power on the systematic and continuous implementation of management entrepreneurship and the improvement of social capital for strengthening cohesion.

Purpose: The old axion to put the customers first (e.g., customers are king, customers are always right) has been taken for granted in the service sector. In addition, many companies in South Korea are providing customer-first education for employees at their contact points to strengthen their competitiveness. However, excessive increase in the psychological power of the customer can lead to a problem of abuse of power, called 'Gap-jil.' Despite these concerns, most companies hardly discard policies to give high priority to customers because of the assumption that it enhances customer satisfaction leading to organizational performance. However, in recent years, some franchise catering companies have posted warnings about the abuse of power by customers, and a movement to pursue a power-balancing between service providers and their customers is spreading. Research design, data, and methodology: This research is conducted to reconsider the principle of the customer-first perspective and to create a basis for arguments that can solve the problem of abuse of power, which is recognized as a serious social problem. In this research, we test and analyze the effect of customers' psychological power in the context of a restaurant on expectation for service and response to service failure. Result: The result of an experimental study shows that the effect of psychological power on customer satisfaction can be somewhat negative. Also, customers with high psychological power are more likely to have high service expectations. Especially high psychological power of customers causes a difference in the expectation level of human factors such as employee attitude, while the difference in expectations of non-human factors such as restaurant atmosphere was not statistically significant. In addition, when customers with high psychological power encounter service failure situation, they are more likely to feel disappointment and regret with a service provider. Meanwhile, the effect of psychological power on complaining behaviors are not significant. Conclusions: The findings of this research provide meaningful implications that the service providers should reconsider their existing corporate culture and management policies that put customers first. In addition, the result of this research is provided meaningful opportunities to review the management philosophy for the company's customers and the education philosophy for the employee education.

The equipment for marine IoT service have to overcome the effect of seawater. Furthermore, the free floating transmitter in seawater will be less affected by the seawater environment. The results of the design and fabrication of antenna, which is embedded in buoy, are shown in this research. The proposed antenna is used to supervise the states of fishing gears in monitoring system for real-name system of electric fishing gear. The selected frequency band of the proposed antenna is 920 MHz, and PCB pattern type is selected for subminiature and light weight. It is confirmed that RF characteristics is more degraded, however, the radiation is gradually upward as the contact surface of buoy with seawater is more broaden through the simulation results. That is, the RF performance of the proposed antenna is more deteriorated but beam radiation characteristics is more suited the marine IoT, the seawater effect is more increased. It is expected that the proposed antenna will contribute the implementation of IoT network based on low power wide area (LPWA) when the degradation of RF performance will be settled.

The UCA is a standard-based approach to utility communications which provides for wide scale integration of functional areas including customer interface, distribution, transmission, power plant, control center, and corporate information systems. Field devices in the power facilities require real-time communications, and they must be interconnected into fieldbus. This study introduces a method of implementing gateway that interfaces UCA and fieldbus. In this study, PROFIBUS and FOUNDATION Fieldbus are selected as candidate fieldbus protocols. Protocol interface in the gateway can be accomplished by mapping objects and services of UCA and fieldbus. MOst of the UCAs CASM objects and services are directly mapped into those of the application and user layers of fieldbus. However, some CASM services are not supported in the application and user layers of fieldbus. This study presents the method of implementing those services. In order to show that the implementation of interface is possible, this study presents pseudo-codes of interface program that maps the objects and services of UCA and fieldbus.

Purpose -The purpose of this paper is to advance the understanding of affective commitment in employees of Korean companies' subsidiaries in Mexico. Specifically, we study the moderating effects of cultural orientation on the relationship between perceived corporate social responsibility (CSR) and affective commitment among these Mexican employees. Research design and methodology - This study was designed to explore the impact of perceived CSR on affective commitment and the moderating roles of collectivism and power distance on the employer-employee relationship. We applied hierarchical regression to survey data collected from 296 employees working for Korean company subsidiaries in Mexico to examine the proposed hypotheses. Results - The results show a significant positive effect from perceived CSR on affective commitment. In addition, this study confirms a positive moderating effect from collectivism and a negative moderating impact from power distance on the relationship between perceived CSR and affective commitment. Conclusions - Drawing upon social identity theory, this study found that Mexican employees' perceptions of their company's CSR and their own cultural value orientations influence affective commitment to the organization. This study extends the understanding of perceived CSR and affective commitment, and particularly demonstrates that the relationship between perceived CSR and affective commitment is influenced by employee collectivistic and power distance orientation.

Modularized charge equalization converter for HEV lithium-ion battery cells is proposed in this paper, in which intra-module and inter-module charge equalization can be achieved at the same time. For intra-module charge equalization, the conventional flyback DC/DC converters of low power and small size are employed, in which all of the primary sides are coupled in parallel for selective charge of the specific under charged cell within the module. For inter-module charge equalization, the flyback DC/DC converters are also added, in which all the secondary windings are electrically linked in parallel for automatic charge balancing among the modules. An engineering sample of forty cells hiring the proposed cell balancing scheme is implemented and its experimental result shows that the proposed modularized charge equalization circuit has good cell balancing performance.
