3rd party content service is a consumer-based wide selection of contents in which IPTV provider believes will enhance the service considerably extending the variety of contents to finally provide a personalized service. Therefore, the combination of 3rd party content services and the IPTV infrastructure creates a good revenue opportunity but they need to be created. IPTV offers to create personalized channels to distribute 3rd party content service. However, the cost of $3^{rd}$ party content delivery is high when the service is provided from a faraway server. IPTV provider requires an effective strategy of replica placement to minimize the cost without a tradeoff on the performance. We propose a cluster-based strategy of replica placement to find the right balance between cost and performance. The results demonstrate the achievement of an outstanding delivery time and low cost.

Purpose: Delivery food continues to grow. In the past, restaurant companies directly hired delivery workers to deliver food, but now, restaurant companies use delivery service platform companies to carry out delivery work rather than directly hiring delivery workers. Therefore, this study seeks to determine the impact of delivery food benefits in the restaurant industry on brand image, trust, and word-of-mouth intention. Research design, data, and methodology: To test the hypotheses of this study, 400 questionnaires were distributed and 340 were collected. Among these, 321 questionnaires, excluding 19 questionnaires that were answered insincerely, were used in the final analysis. Result. First, delivery food benefits were found to have a significant impact on brand image and trust. Second, brand image was found to have a significant effect on trust and word-of-mouth intention. Third, trust was found to have a significant effect on word-of-mouth intention. Conclusions: First, existing research focused on studying the attributes of delivery food in the restaurant industry, but this study studied the benefits that consumers can obtain through purchase among these attributes. Second, delivery food restaurants need to design promotions and advertisements in a way that displays coupons, points, or mileage. Third, quick delivery of orders can be a competitive advantage for delivery food restaurants.

Purpose: Healthy and balanced meal is very important for the elderly to maintain the quality of life in community. Senior meal delivery system and congregate meal services have been played an important role to prevent premature institutionalization of the elderly. Food delivery system and lunch service spaces for the Korean elderly were mostly focused and limited on low-income family. The purpose of this study is to analyze community food services environments for the elderly in the UK, the U.S. and Japan for the possibility of applying those service spaces to Korean community. Methods: Lunch service spaces of these three countries were investigated by literature research and visiting of venues. Pilot study of the elderly meal services in Seoul was done for comparing environments and future research. Results: Lunch service spaces in three countries were mostly community based for accessibility and the types of management were various for the elderly to choose the most suitable services for them. The group dining spaces are usually small and designed to give de-institutional atmosphere. Implications: Food service environments for the elderly in Korea should develop more community based model of food delivery and congregate meal service spaces as well as more de-institutionalized design of those spaces.

With the activation of non-face-to-face services, the use of delivery service platforms has been increasing. At this juncture, this study empirically analyzed the impact of customer experience on customer satisfaction and customer loyalty in the context of delivery service platforms. Specifically, the study segmented customer experience into four sub-factors: product experience, moments of truth, outcome focus, and peace of mind, and analyzed their individual impacts on customer satisfaction and customer loyalty. The independent variables, representing customer experience, were divided into the aforementioned four sub-factors. The mediating variable was customer satisfaction, and the dependent variables were repurchase intention and recommendation intention. A survey was conducted with customers who have used delivery service platforms, and 300 valid responses were utilized for the analysis. The empirical results are as follows: all four sub factors - product experience, moments of truth, outcome focus, and peace of mind - significantly and positively influenced satisfaction with the delivery service platform. Among these, peace of mind had the most substantial impact. Additionally, customer satisfaction was found to mediate the relationships between product experience, moments of truth, outcome focus, peace of mind, and both repurchase intention and recommendation intention. This study is academically significant as it segments and examines customer experience into four distinct factors. Practically, it highlights the importance of providing peace of mind to reassure customers as the most crucial factor in enhancing their satisfaction and loyalty.

This study examined the consumer response of the current O2O service between service types. Previous studies mainly focused on the quality factor of O2O service or Technology Acceptance Model or extended TAM, This study is different from the fact that there are differences in factors that consumers consider important and consumer reactions by service type. It is also significant that we compared between representative food delivery services and car sharing services that are actively used among O2O services. As O2O service is closely related to consumer's life, this study chose three factors that the issue of personal information security and trust of intermediary platform companies, and finally subjective norm based on individuals and groups who are aware of new O2O service. To test hypotheses, data were collected and analyzed for 301 samples, focusing on delivery and car sharing service, As a result, the delivery service among the O2O services was more positive to attitude toward service in the consumer group with lower personal information security, trust in platform, and subjective norm than car sharing service. Based on these results, implications and future research directions were presented.

This study empirically analyzed the effect of perceived injustice on service recovery measures proposed by online food delivery service (OFDS) companies on consumer disappointment. This study adopted interaction justice, information justice, procedural justice, and distributive justice as sub-variables of justice perception based on the justice theory. In addition, the differences by generation (MZ generation and other generations) were examined in the relationship between negative word-of-mouth behavior and switching intentions due to service recovery failure. An online survey was conducted targeting 250 adult consumers in the U.S for the empirical analysis of this research model. The results of the data analysis demonstrated that negative perceptions about the procedural justice and distributive justice among the service recovery strategies had a positive effect upon the consumer's disappointment. Furthermore, it was confirmed that the consumer's disappointment due to the perceived injustice of the service recovery strategy had a positive effect on the consumer's negative word-of-mouth behavior and switching intentions. The verification results of the moderation effect in the relationship between negative word-of-mouth behavior and switching intention, it was found that the younger the age(MZ generation), the higher the possibility of causing dysfunctional behavior. This study expands the scope of related research by presenting a new perspective on the justice perception in the service recovery process by verifying dysfunctional behavior of consumers caused due to the failure of the service recovery strategy. It is believed that the results of this study will be used as basic data for the establishment of practical strategies for OFDS companies to prevent double defection of their customers.
