In the current situation, due to the  exposure of nurses with the corona epidemic, there is porbably too much work pressure on them, which can be a reason for the increase in job burnout among them. The aim of this study was to investigate the mediating role of problem solving skills in the relationship between job meaning and job burnout among nurses during the corona epidemic.

This descriptive correlational study was performed using structural equation modeling. The statistical population of the present study included all the nurses who were working in Imam Khomeini Abadeh and Khatam-Al-Anbiya Abarkooh hospitals during the corona epidemic in 2021-2022. From these, a sample of 220 nurses was selected using available sampling method. In order to collect data, the Work and Meaning Inventory of Stiger et al. (2012), burnout questionnaire of Yildirim and Solmaz (2020), and Basader’s (1999) problem solving questionnaire were used. Data were analyzed by Pearson correlation test and structural equation modeling.

The results of the study confirmed the direct relationship between the variables of job meaning and job burnout, as well as the mediating role of problem solving skills in the relationship between job meaning and job burnout among nurses during the corona epidemic (p<0.001).

The job burnout in nurses can be reduced by increasing job meaning and improving problem-solving skills, and it leads to an increase in the quality of medical care and patient satisfaction.

Nurses, as members of the therapeutic team in health care centers, are faced with challenging decisions, moral issues and problems. The purpose of this study was based on examining the mediating role of cognitive flexibility in the relationship between Professionl Values and moral sensitivity among nurses during the corona epidemic.

This study was a descriptive-correlational study. By applying quota convenience sampling method, 220 subjects were selected among the nurses working in Khatam Al-Anbia (PBUH) hospitals in Abarkooh and Imam Khomeini (RA) towns, Abadeh town in order to participate in the study. To collect data, The Weis and Shank (2009) Professionl Values Scales, Lutzen et al. (2006) and Dennis and Vanderwall (2010) Cognitive Flexibility Questionnaires were used. The Data were analyzed through Pearson's correlation test and structural equation modeling.

Ethical Considerations: 

In this study, criteria concerned with moral principles as confidentiality, personal satisfaction and freedom of participants in cooperation or non-cooperation during the study process have been observed.

The findings of the study demonstrated that there is a positive and significant relationship between the variables of occupational values and moral sensitivity, Professionl Values and cognitive flexibility (P<0.001). Moreover, it confirmed the mediating role of cognitive flexibility in the relationship between Professionl Values and moral sensitivity among nurses during the corona epidemic (P<0.01).

Considering the findings of the present study, in order to increase Professionl Values, it is recommended that appropriate strategies in line with addressing to the principles and criteria related to this variable, including social, emotional and economic support, especially in the nursing field, should be exerted to be strengthened their moral sensitivity by affecting their cognitive flexibility.

Graphene oxide (nGO) is considred as a good nano carrier for enzymes to protect them in biological media against proteolytic activity and extend their activity and stability. In this paper, we reported a new inexpensive collagenase assay using graphene oxide nanosheets (nGO) for Coomassie brilliant blue (CBB) staining. Collagenase enzymes was attached to nGO and added to microwells containing dried collagen that covered bottom of wells. The optical absorption (590nm) was linearly increased parallel to increasing the concentration of collagen. The concentraton of collagenase enzyme can be measured by this assay after staining with CBB after overnight incubation with collagen. This technique is a simple, safe, inexpensive and relatively fast method for evaluation of collagenase enzyme and could be applicable for pharmaceutical and industrial purposes.
