Electric power is an important element in any modern economy. The availability of a reliable power supply at a reasonable cost is important for the economic growth and development of a country. Electric power utilities throughout the world therefore strive to meet customer demands economically with high quality and reliability. As the power industry moves towards open competition, therefore, there has been a call for a methodology by which to evaluate power system reliability through the use of customer interruption characteristics. This paper presents the results of an investigation and analysis of interruption characteristics of an industrial customer in Korea. This study used a direct visit survey to determine the investigation and analysis of electric service quality and the characteristics of industrial customers in Korea. A customer survey conducted throughout Korea via personal interviews of 660 sample customers is presented here. Variation according to characteristics of interruption such as duration, time of day, frequency and day of interruption was also investigated

This study identified the brand personality of domestic take-out coffee shops and examined its effects on customer satisfaction and brand loyalty. The research subjects were college students in Busan who visited a coffee house. Overall, four major empirical results were obtained. First, five factors of brand personality were identified: "energy", "competence", "familiarity", "reliability", and "sophistication". Second, all brand personality factors had significant effects on customer satisfaction, but "familiarity" (${\beta}$=0.429) and "reliability" (${\beta}$=0.381) appeared to have the greatest effects. Third, brand personality factors had significant effects on brand loyalty, with"reliability" (${\beta}$=0.447) appearing to have the greatest effect on brand loyalty. Fourth, customer satisfaction had a significant effect on consumer brand loyalty. These results show that brand personality can be an important means of marketing differentiation in an intense competitive coffee market atmosphereto increase customer satisfaction and build brand equity.

Purpose - Current study aimed at investigating customer experience types (gain vs. loss avoidance performance experience and hedonic vs. reliability imagery experience) and their influences on satisfaction and positive emotion as antecedents of customer engagement. It also explored moderation role of regulatory focus in the influence of each experience type on satisfaction and positive emotion. Research design, data, and methodology - 416 Vietnamese local tourists were selected to test hypotheses by structural equation model in AMOS 21.0. Results - First, customers actually achieving gain or avoiding loss are more satisfied. Second, customers with hedonic and reliability imagery experience feel more positive emotion. Third, both positive emotion and satisfaction have positive influences on customer engagement. Last, regulatory focus moderates the positive effects of either gain or loss avoidance performance experience on satisfaction and also moderates the positive effects of either hedonic or reliability imagery experience on positive emotion. Conclusions - Focusing on both cognitive satisfaction and affective emotion resulted from experience, this study could advance customer engagement theory. Managerially, brand managers should induce gain performance and hedonic imagery experience (loss avoidance performance and reliability imagery experience) from promotion (prevention)-focused customers to enhance their engagement.

SAIDI(System Average Interruption Duration Index) is the index that signifies the power quality of customers. SAIDI is also used to know how well utilities operate their systems. The annual interruption time in the areas that consists of widely distributed customers, is generally longer than that in the areas that consists of heavily concentrated customers. The Reliability index of huge system is not necessarily better or worse than that of small system, because SAIDI is irrelevant to the total amount of power sold or the total number of customers. This paper proposes a customer density very relevant to SAIDI. The proposed customer density is used to modify the existing SAIDI to more clearly express the service level of power supply. A modified WSAIDI(weighted SAIDI) can be a useful indicator helping utilities improve the reliability of their systems and customers evaluate the service level of receiving power.
