Introduction: Nurses' job satisfaction is a serious issue for health care systems so that decreased job satisfaction can cause problems for nurses and health systems. Job satisfaction can be affected by sleep quality and the morningness- eveningness preference (chronotypes) of nurses. The present study aimed to determine the predictive power of job satisfaction by sleep quality and morningness-eveningness chronotypes of nurses working in Urmia teaching hospitals in 2020. Methods: A total of 327 nurses working in teaching hospitals affiliated to Urmia University of Medical Sciences were enrolled in the study. Sampling was conducted using simple random method. Data were collected using Demographic information questionnaires, Pittsburgh Sleep Quality Index, Minnesota Satisfaction Questionnaire, and Composite Scale of Morningness. Data were analyzed using descriptive statistics, measures of central tendency, Pearson correlation coefficient, independent samples t-test, two-way ANOVA, and linear regression analysis. All statistical analysis were conducted using SPSS software version 16.0 (SPSS Inc., Chicago, Ill., USA). Results: The results of linear regression analysis and Pearson correlation coefficient indicated that there is a significant correlation between the job satisfaction and the sleep quality in nurses as an improvement in sleep quality leads to higher job satisfaction (P <0.01) and the sleep quality is one of the predictors of job satisfaction (P = 0.002). However, there was no significant correlation between the nurses’ job satisfaction and their morningness-eveningness chronotypes (P> 0.01). Conclusion: Nurses with higher levels of sleep quality have higher job satisfaction, although the morningness-eveningness chronotypes of nurses have no significant effect on their job satisfaction.

Ellipsoidal Model

Eigenvolumes calculated from a linear transformation model were found previously to be linearly related to balloon volumes in excised hearts. The present study analyzed endocardial marker kinematics in intact, contracting left ventricles by biplane cinefluorography. Ejection fractions of the linear transformation model were compared by linear regression analysis with those of an ellipsoidal model, whose ejection fractions had been documented previously in closed and open-chest dog preparations. Data from 10 dogs indicated a correlation coefficient of 0.98 and a regression equation with close similarity to the line of identity. Ejection fractions calculated from the linear transformation model are concluded to be proportional to actual ejection fractions in intact, beating left ventricles.

Conjugated Bilirubin

Abstract A new, simple, and rapid assay for conjugated bilirubin that does not require serum-matrix standards was developed by using the enzyme bilirubin oxidase (EC 1.3.3.5). This procedure can also be modified to measure total bilirubin. Measurements from these assays were compared with results obtained with the Sigma 605 (Jendrassik-Gróf method), Sigma 550/551 (Walters-Gerarde method), and Kodak Ektachem (BuBc) bilirubin assays. The one-year study involved serum specimens from 283 infants younger than 30 days. Linear-regression analysis of data for conjugated bilirubin collected by this assay and by the Kodak Ektachem assay yielded a slope of 0.975, an intercept of 0.088, an Syx of 1.47 mg/L, and a correlation coefficient of 0.94 for a total of 49 specimens. Correlation was also good (r = 0.95) between results for total bilirubin by this assay and both the Sigma 605 and the Kodak Ektachem methods.
