Considering the impact of service quality in the hemodialysis departments on the survival rate and quality of life (QoL) of patients, it is important to monitor the performance of this department. In this regard, identifying key performance indicators (KPIs) can be useful. This study aims to determine the k KPIs in the dialysis management dashboard.

This is a descriptive cross-sectional study that was conducted in 2022. Participants were 346 nephrology specialists in Iran which were selected using the census method. The data collection tool was a researcher-made questionnaire with acceptable validity and reliability. Data were analyzed using SPSS software, version 16.

A total of 40 KPIs were identified in three main categories: Structure (n=16), process (n=11), and outcome (n=13). The most important structure-related KPIs were: Underlying cause of kidney failure, comorbidity diseases, blood type, history of viral diseases, dry weight, and history of kidney transplantation. The most important process-related KPIs were: Type of filtration, type of vascular access, and duration of dialysis. The most important outcome-related KPIs were: Kt/V, urea reduction ratio, normalized protein catabolic rate, and fistula infection.

Accurate identification of KPIs and their use in continuous monitoring of dialysis department performance can help improve service quality and patient safety.

The aim of this study was to investigate the mediator role of enjoyable experience in the relationship between similarity with the team and the re-visit of football fans to the website of Esteghlal Club. The statistical population of the study was the fans of Esteghlal football team, which collected a total of 230 acceptable samples. The instruments used were the identity card questionnaire (Wann & Branscombe, 1993), the enjoyable experience (Okas and Carlson, 2010 and Hsu et al., 2017) and the re-visit intention questionnaire (Cronin et al., 2000). The face validity of the questionnaire was assessed by 5 professors and PhD students in sports management and then distributed online in the study population. Smart PLS software was used to measure the Farshiat. Reliability, convergence validity and divergent validity indicated that the external model of the research was desirable. Also, the model fit (SRMR) 0.09 confirmed the goodness of fit. Findings showed that assimilation with the team has an effect on enjoyable experience (0.49) and intention to revisit (0.26). Also, enjoyable experience had an effect on intention to revisit (0.57). In general, increasing the level of solidarity of fans with their favorite teams leads to close emotional and emotional connections of fans with the teams' websites, and when these connections are accompanied by a pleasant experience on the site, it causes more visitors to desire from the sites of football clubs.

The main aim of this paper is the study of the strength of AM-2 matting plate made of Al6061-T6 under impact loads due to aircraft landing. In this study, the damping effects of the aircraft tire have been modeled by means of Mooney-Rivlin hyperelastic criterion. Effective parameters such as the landing vertical velocity at 1.5, 2, 2.5, and 3 m/s; the landing horizontal velocity at 42, 45, 50, 55, and 60 m/s; the CBR value of subgrade at 5, 10, 15, 20 and 25; and the thickness of subgrade at 160, 200, 300, and 500 mm, have been studied. The results showed that the stresses in matting plate increases with increasing both horizontal and vertical components of landing velocity, but decreases by increasing the CBR value. On the other hand, considering the subgrade thickness greater than 300mm has no significant effect on stresses. In order to have safe situation, the CBR value be 15 and greater has been recommended. Comparison of the results with those obtained without modeling the damping effects showed that the stresses be 15% greater in conditions without modeling damping of the tire.
