Purpose: Nurses' infection prevention and control responsibilities have been emphasized owing to the increasing infection rate in long-term care facilities in South Korea. The aim of this study was to explore nurses' perspectives on challenging situations and the areas of improvement related to their role in infection management. Methods: An exploratory descriptive qualitative study was conducted with a purposive sample of 15 nursing staff from five long-term care facilities. A focus group interview with semi-structured questions was conducted between January and May 2017. The study participants' discussions were analyzed using conventional content analysis with line-by-line coding. Results: The participants discussed the breadth of challenges interfering with their ability to provide optimal infection care, from practical human resource management issues to organizational and environmental barriers, and laid a foundation based on which lacking areas can be improved. The analysis produced key themes centered on healthcare personnel-related professionalism, professional role boundaries, daily workflow and management, interdisciplinary collaboration, standards and protocols, and technological infrastructure. Conclusion: Although participants expressed negative feelings toward the constraints in long-term care facilities, they demonstrated the willingness to create a positive change and offered suggestions for improvement and support to improve resident safety and care management. Therefore, special attention should be paid to nurses' perspectives on their work and roles regarding infection control practices and supporting them with available sources.
In this paper, a monopulse sensor which determines a target location using amplitude-comparison monopulse technique is presented. This sensor can allow the missile to track the target when additional jamming signals are not presented. Then, we applied the spot noise jamming technique to the monopulse sensor. Based on the simulation results, we can effectively figure out the performances of the spot noise jamming technique for the monopulse sensor in various jamming scenarios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
