Cloud services have become the core infrastructure of the digital economy as a basis for collecting, storing, and processing large amounts of data to trigger artificial intelligence-based services and industrial innovation. Recently, cloud services have been spotlighted as a means of responding to corporate crises and changes in the work environment in a national disaster caused by COVID-19. While the cloud is attracting attention, the speed of adoption and diffusion of cloud services is not being actively carried out due to the lack of trust among users and uncertainty about security, performance, and cost. This study compares and analyzes the "Cloud Service Quality and Performance Management System" and the "Cloud Service Certification System" and suggests complementary points and improvement measures for the cloud service quality and performance management system.

Purpose: This study was based on curation commerce that has been rapidly developing. It looked into the effect of curation commerce's quality of service factors (information quality, information interest quality, interaction quality, and personalization quality) on satisfaction and the mediating effect of consumer empathy and shopping value between service qualities and consumers' satisfaction with curation commerce. Research design, data, and methodology: The survey was conducted on 273 consumers who used Chinese curation commerce services. The research data was analyzed using the Smart PLS 3.0 program. The empirical analysis was conducted with reliability and validity analyses of the questionnaire and hypothesis test. Results: As a result, only the quality of information had a direct impact on satisfaction. The remaining service quaility factors (information interest quality, interaction quality, and personalization quality) were found to affect satisfaction through utilitarian value or consumer empathy. Conclusions: This study is meaningful in that it selected the service quality factors experienced by consumers about curation commerce services in line with the bright market prospects of curation services. In addition, the significance of this study was to reveal the psychological mechanism of the process in which the quality of service reaches consumer satisfaction.

The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.

Second, the key variables of each hospital which turned out significantly different in quality of social work service were the departmental form of social work unit, unit leader's age, educational level, field experience, and job rank. Third, the level of quality of social work service correlated positively with the field experience of unit leader, the size of social work unit, the job rank of the unit leader. Conclusion : The most influential variables to the quality of social work service proved departmental form of social work unit, leader of social work unit.
