As tactical networks are gradually shifting toward IP-based flexible operation for diversified battlefield services, QoS(Quality-of-Service) coordination for service differentiation becomes essential to overcome the heterogeneous and scarce networking resources limitations. QoS coordination for tactical network traffic should be able to monitor and react the dynamic changes in underlying network topology and service priorities. In this paper, by adopting the emerging cloud-native service mesh concept into tactical network context, we study the feasibility of intelligent QoS coordination by employing tactical service mesh(TSM) as an additional layer to support enhanced traffic quality monitoring and control. The additional TSM layer can leverage distributed service-mesh proxies at tactical mesh WAN(Wide Area Network) nodes so that service-aware differentiated QoS coordination can be effectively designed and integrated with TSM-assisted traffic monitoring and control. Also, by validating the feasibility of TSM layer for QoS coordination with miniaturized experimental setup, we show the potential of the proposed approach with several approximated battlefield traffics over a simulated TSM-enabled tactical network.

This study attempts to investigate how healthcare service quality impacts upon hospital reputation, service value, and customer satisfaction. Additionally, the association of customer satisfaction with hospital loyalty and the mediation role of service value and reputation are examined. Analysis results can be summarized as followings: First, the procedural convenience and efficiency have significant impact upon customer satisfaction but personnel service and service scape do not significantly affect customer satisfaction. Second, the personnel service and service scape have significant impacts upon both the service value and hospitals' reputation. Third, service value and hospital reputation contribute significantly to the customer satisfaction. Fourth, customer satisfaction enhances significantly customer's satisfaction and intention to recommend. We conclude that a regional medical center should be able to offer high quality medical services to its customers to satisfy or delight them. Only the satisfied customers will have intention to revisit the medical center or to recommend it to their friends.

This study attempts to analyze some determinants of consumers' medical service quality and their complaining behavior. The results can be summerized as follows: 1. The determinants of consumers' perceived medical service quality could be categorized as five factors; i.e. nursery, hospital environment, medical doctors, other staffs service fee. Among them nursery sector consists of 32% variance. 2. According to the discriminant analysis, those determinants are of great value to distinguish between satisfied/unsatisfied group. The hit ratio was 85.4% which is relatively high score. 3. The type of complaining behavior could be grouped into no action, private and public complaining behavior. Most of respondents belonged to no action group and a few showed private complaining behavior. Any respondents who were willing to show public complaining behavior could not be found out. 4. These variables which influence complaining behavior were preconception toward hospital, barrier to complaining process and expected complaining behavior. Among them the first one was most influential variable. 5. In order to distinguish between complaining/non complaining behavior group, discriminant analysis was done. The result showed the above three variables had a significantly discriminatory power, the hit ratio reaching above 70%. In summary, we can see that consumers' evaluation on the whole medical service depends on the external factor such as staffs' attitude or hospital facilities due to the lack of their ability to evaluate highly specialized service like doctor's treatment.

The purpose of this study was to measure the effects of service quality mediating the linkage among food and beverage price, restaurant image and value. A total of 273 questionnaires were completed. MANOVA, ANOVA and ANCOVA were used to measure the mediating effect of service quality on the relationships among food and beverage price, restaurant image, and value. The effects of food and beverage price and restaurant image on service quality and value were statistically significant. As expected, when food and beverage price and service quality were regressed on the value, the service quality was significant and the effect of the food and beverage price was reduced. Moreover, when restaurant image and service quality were regressed on the value, the restaurant image and service quality had a significant effects on value. The results demonstrated that service quality played a mediating role in the relationship between food and beverage price and value, and between restaurant image and value.
