Material and Methods: This cross-sectional study was conducted on 273 of 914 nurses working in the hospitals affiliated to Ardabil University of Medical Sciences. The sample size (N= 273) determined via Krejcie and Morgan table were asked to fill out the three questionnaires of Servant leadership style (by Gholipour et al), organizational learning (by Chiva et al) and job engagement (by Salanova and Schaufeli). The data was analyzed by SPSS-21, using descriptive statistics (data frequency tables, mean, and standard deviation) and inferential statistics (stepwise multiple regression method and Pearson correlation). 

Results: The results showd that there was a positive and significant relationship between servant leadership, organizational learning, and job engagement (p≤0.01). Furthermore, servant leadership and organizational learning can predict job engagement. 

Conclusion: The improvement of organizational learning and servant leadership can enhance the nurses’ job engagement.

Material and Methods: This descriptive study was conducted on 500 parturients, in Taleghani hospital of Tabriz, divided into two equal groups of latent phase (N = 250) and active phase (N=250). For data collection, we used a demographic Questionnaire, a Checklist for assessing the third and fourth labor stages and the results of mothers' physical examination (pre discharge and 10 days after delivery).

Results: In accordance with age, number of pregnancy, delivery , abortion, stillbirth and the number of natural pregnancy, the difference between two groups was not significant. But about the complications of 4th stage of labor, postpartum hemorrhage and pre- discharge Hb & Hct, the difference was significant. Apgar score in the first minute (p<0.03), Cord ABG (p<0.001) and the interventions conducted on infants such as resuscitation (p<0.001) were significantly different between two groups of latent and active phase. 

Conclusion: Admission in the latent phase is accompanied by increased complications and early medical interventions. Hence, admitting in latent phase is not recommended unless there are some specific medical indications.
