The purpose of this research study is to present some new operations, including rejection, symmetric difference, residue product, and maximal product of Pythagorean fuzzy graphs (PFGs), and to explore some of their properties. This research article introduces certain notions, including intuitionistic fuzzy graphs of 3-type (IFGs3T), intuitionistic fuzzy graphs of 4-type (IFGs4T), and intuitionistic fuzzy graphs of n-type (IFGsnT), and proves that every IFG(n−1)T is an IFGnT (for n ≥ 2). Moreover, this study discusses the application of Pythagorean fuzzy graphs in decision making.
The q-rung orthopair fuzzy set is a powerful tool for depicting fuzziness and uncertainty, as compared to the Pythagorean fuzzy model. The aim of this paper is to present q-rung orthopair fuzzy competition graphs (q-ROFCGs) and their generalizations, including q-rung orthopair fuzzy k-competition graphs, p-competition q-rung orthopair fuzzy graphs and m-step q-rung orthopair fuzzy competition graphs with several important properties. The study proposes the novel concepts of q-rung orthopair fuzzy cliques and triangulated q-rung orthopair fuzzy graphs with real-life characterizations. In particular, the present work evolves the notion of competition number and m-step competition number of q-rung picture fuzzy graphs with algorithms and explores their bounds in connection with the size of the smallest q-rung orthopair fuzzy edge clique cover. In addition, an application is illustrated in the soil ecosystem with an algorithm to highlight the contributions of this research article in practical applications.
Introduction: Nursing is a very demanding career. In nursing work nurse’s work not only have tons of things to get done. Nurses scores in time management were more than those of men, with statistically significant difference: (p<0.05). There was a positive significant relationship between individual skills and organizational skills in time management (p<0.05). The purpose of this study was to determine the factors affecting time management of professional nurses. Methodology: A descriptive cross sectional analytic study was conducted at government hospital of Lahore. Data was collected from 211 registered nurses using convenient sampling. Data was analyzed using SPSS version 21. Results: There is statistically significant differences, in the significance level 0.05, of effective time management for nurses according to gender. Professional nurses spend much time in gossiping of both gender as (p <0.05), time allocated for socialization were more among female nurses Shortage of staff contributes poor time management towards patient care, working under pressure is significantly associated with poor patient care (p <0.05). Nurses spend much time using mobile phone is statistically significant (p <0.05). Conclusion: Time management is very crucial to the nurses and helps them to plan for their available time and use it to manage their tasks. This research identified and evaluated time management in professional nurses. Based on the results, it was found that shortage of staff contributes poor time management towards patient care, working under pressure affect patient care negatively, proper supervision will improve time management. It is also conclude that time management is necessary for medical workers, especially nurses. Thus, it would be interesting to conduct comparative cultural studies to better evaluate time management.Int. J. Soc. Sc. Manage. Vol. 5, Issue-3: 231-235
