The purpose of this research is to identify causalities among service quality, service value, customer satisfaction and customer loyalty and to compare the causalities between in-patients and out-patients. A multi-group structural equation model was used to test the hypothesis of conceptual model. Empirical results indicate that two factors such as assurance and empathy have direct impact on service value and customer satisfaction in both the patients. In the results of multi-group comparison test, however, the path coefficients from service value to customer loyalty and from customer satisfaction to customer loyalty were different across the two groups. In out-patients, customer loyalty is more positively related with service value. In in-patients, customer loyalty is more positively related with customer satisfaction. It is proven that service quality influences customer loyalty. Therefore To compete successfully in today's volatile & competitive medical markets, the hospital needs to manage the service quality, considering the type of patients.

Currently, research on network functions virtualization focuses on using microservices in cloud environments. Previous studies primarily focused on communication between nodes in physical infrastructure. Until now, there is no sufficient research on group key management in virtual environments. The service is composed of microservices that change dynamically according to the virtual service. There are dependencies for microservices on changing the group membership of the service. There is also a high possibility that various security threats, such as data leakage, communication surveillance, and privacy exposure, may occur in interactive communication with microservices. In this study, we propose an ID-based group key exchange (idGKE) mechanism between microservices as one group. idGKE defines the microservices' schemes: group key gen, join group, leave group, and multiple group join. We experiment in a real environment to evaluate the performance of the proposed mechanism. The proposed mechanism ensures an essential requirement for group key management such as secrecy, sustainability, and performance, improving virtual environment security.

Purpose: The current study was done to identify individual- and group-level factors associated with health care service utilization among Korean medical aid beneficiaries by applying multilevel modeling. Methods: Secondary data analysis was performed using data on health care service reimbursement and medical aid case management progress from 15,948 beneficiaries, and data from 229 regions were included in the analysis. Results: Results of multilevel analysis showed an estimated intraclass correlation coefficient (ICC) of 18.1%, indicating that the group level accounted for 18.1% of the total variance in health care service utilization, and that beneficiaries within the region are more likely to share common features with regard to health care service utilization. At the individual level, existence of disability and types of medical aid beneficiaries showed a significant association, while, at the group level, social deprivation index, and the number of beneficiaries and case managers within the region showed a significant association with health care service utilization. Conclusion: The significant influence of group level variables in health care service utilization found in this study indicate a need for group level approaches, such as policy change and/or promotion of community awareness.

The purposes of this study were to identify the attributes of food and service quality, to examine the levels of satisfaction and plate wastes leftover in school meals and to determine the relationship between student satisfaction and plate wastes. A questionnaire was administrated to 1000 elementary students. The respondents comprised of 505 boys and 494 girls. The satisfaction score with the food service quality was rated as 'average', with a score of 3.06 out of 5. The quality attributes of the food service were categorized into three aspects, which included food, service and hygiene. The satisfaction scores for the food- and hygiene-related factors were 3.20 and 3.24, respectively. However, the aspect of service was rated at 2.74, indicating a low level of satisfaction. The intake rates of soup, kimchi, fish and vegetables were lower than those of other types of foods. Two groups, a no-leftovers group and a leftovers group, were classified based on whether students ate all or left foods. The satisfaction scores for the school food service attributes between the two groups revealed that the no-leftovers group was more highly satisfied with the food service quality than the leftovers group (p＜0.001).

Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.
