This study examined the variables that affect whether consumers change broadband internet services by examining their past experiences and intention to switch carriers by targeting consumers who have switched broadband internet service providers. Among adult consumers who intended to switch broadband providers, 341 people who had experience were subject to logistic regression analysis using SPSS for Windows ver. 17.0 to examine frequencies, means, percentages, and factor analysis. The following results were revealed. First, the targets were currently using broadband internet service in the order Company S > Company L > Company K > others. Excluding the others, Company K had the most conversions (from 96 to 78), followed by Company S (from 107 to 97), and Company L (from 43 to 97), which more than doubled the number of subscribers. The reasons for switching carriers in the past were as follows: for Company K, consumers switched to other companies because of unsatisfactory fee services; for Company S, consumers switched to other companies because of quality, advertising and promotional activities, and commitment periods ending; for Company L, the consumers switched to other companies because of fee, quality, and service; and for other companies, the consumers switched to other services because of unsatisfactory quality. Second, the analysis of the elements that determined whether a consumer will switch broadband internet service providers showed that college graduates and individuals who had switched carriers voluntarily in the past were more likely to switch to a new broadband internet service provider. Furthermore, passive consumers had a higher probability of switching. Moreover, when consumers were less satisfied with the fees and services, there was a greater chance of switching to another company.

In call centers where customers contact a firm's customer service without face-to-face interaction, customer service representatives (CSRs) determine its service competitiveness. In other words, a firm's service excellence relies on its CSRs. Drawing on the concept of agility from service and information technologies studies, this study conceptualizes customer response capability as a variable consisting of customer response expertise and customer response agility, and further verifies its effects on customer service performance. Moreover, this study examines whether a firm's digital and human knowledge resources are related to CSRs' customer response capability. To empirically test the proposed hypotheses, the partial least squares analysis is conducted with a total of 371 responses collected on CSRs from two insurance call centers. The findings indicate that a firm's digital and human knowledge resources enhance CSRs' customer response expertise and customer response agility, thereby increasing customer service performance. The results draw the conclusion that CSRs' customer response capability is a key antecedent of superior customer service.

The purpose of this study is to explore ways of service recovery and procedures through the service failure cases depending on the employee capacity that leads to improving quality of the airline cabin service. This study was tested using the failure case of airline in korea. Since interrupting and discontinuing of customer service affect customer defections, customer satisfaction must quickly respond to the service's error situation. The service of the cabin crew is closely related to the customer's evaluation, the direct connection. Customer's objectives are to meet employee needs for service recovery and to recognize and analyze customer perceptions of human resources services, restore customer expectations and maintain contracts with customers. Therefore, this study proposes a set of strategies for effectively preventing and responding to customer related service failure in the airline cabin service.

This paper tried to research the relationship among the passenger's satisfaction and expectation of in-flight service quality, overall satisfaction and passenger's Loyalty by emphasizing on two groups of passengers and cabin crews from K-airline to find out which service quality area should be focused on for pursuing premium in-flight service. Such six service quality areas as in-flight equipment, food&beverage, duty-free sales, service ability, service image and specialized service were conceived and survey questions were made based on relevant previous researches. The analysis has used the data of 281 passengers and 336 cabin crews from K-airline. According to the analysis, in physical service factors, passengers perceive satisfaction from duty-free sales contributes to overall service satisfaction. However, cabin crews believed in-flight equipment and food&beverage are important to overall service satisfaction. In human service factors, both groups seemed to agree service ability and service image have a positive impact on overall service satisfaction. Among service satisfaction factors, the customer's satisfaction from cabin crew's service ability(service response, professional knowledge and foreign language skill) is also proven to be directly connected to customer loyalty.

This paper presents the psychomotorik-based play activities executed by the social robot at home which helps children's social and emotional development. Based on the theory and practice of the psychomotorik therapy, the play activities were implemented in the close collaboration between psychmotorik experts, service designers and robotics engineers. The designed play activities are classified into four categories depending on the main areas of child development. The robotic system that can express verbal and nonverbal behaviors was developed in order to play games with children and but also to make children have continuous interest during the play activities with it. Finally, the psychomotorik-based play service scenario and interactive robot system were validated by the expert group from the domain of child psychotherapy. The evaluation results showed that the play service and the robot system were appropriately developed for children from the experts point of view.
