In this study, iron oxide/cellulose acetate nanocomposite was prepared by electrospinning method and its performance was evaluated for removal of arsenic. Here, oleic acid coated magnetite nanoparticle was synthesized by co-precipitation method and was impregnated in cellulose acetate solution. This magnetite impregnated polymer solution, was electrospun to form nanocomposite polymer fiber. The cellulose acetate/iron oxide nanocomposite membrane was characterized by SEM and FTIR. The magnetic properties of composite nanofibers were characterized by using vibrational sample magnetometry analysis. The nanocomposite was used to remove arsenic ions from aqueous solution. Batch adsorption experiments were carried out to study the sorption behavior of arsenic ions as a function of pH, contact time and initial concentration. Experimental results showed that the maximum capacity of the cellulose acetate-iron oxide nanocomposite membrane for removal of arsenic from low concentration is 0.36 mg/g at pH 9. For better investigation of the adsorption mechanism, two isotherm models, Langmuir and Freundlich were tested. Based on the isothermal results, adsorption data were fitted well to Langmuir isotherm. The reusability of the nanocomposite membrane was confirmed for several adsorption and desorption processes by acid-alkali treatment.

COVID-19 is rapidly expanding around the world and is one of the most important health problems. The purpose of the study was to determine preventive behaviors from COVID-19 and its determinants based on some constructs of the Health Belief Model.

This cross-sectional study was conducted on 2504 citizens of Rafsanjan in 2020 that were randomly selected by cluster sampling method. Data were collected using a behavior and Health Belief Model constructs (HBMs) researcher-made questionnaire based on the Internet. The validity of the questionnaire was evaluated by ten specialists, and its reliability was assessed by Cronbachchr('39')s alpha coefficient. Data analysis was conducted in SPSS 18 by applying statistical tests such as Pearsonchr('39')s correlation coefficient, independent t-test, One-Way ANOVA, and linear regression.

The means score of knowledge, attitude, perceived susceptibility, severity, benefits, barriers, and preventive behavior were 83.13±10.72, 81.17±8.55, 79.28±17.19, 74.47±14.65, 84.32±16.11, 69.27±14.31, and 87.35±11.16, respectively. There was a significant correlation between preventive behaviors with knowledge, attitude, and HBMs (p<0.001). The attitude was the strongest predictor for adopting preventive behaviors (B=0.446, p<0.001). In total, knowledge, attitude, and HBM constructs predicted 36.8% of the preventive behaviors for COVID-19.

There is a significant correlation between adopting preventive behaviors for COVID-19 with knowledge, attitude, and HBM constructs.

Mindfulness is a therapeutic process that refers to purposeful, non-judgmental attention, along with accepting and acknowledging experiences and living in the moment. This study was conducted to evaluate the effectiveness of mindfulness training on psychological distress and perceived stress in nursing students.

The method of this research was semi-experimental and pre-test-post-test method with control group. The statistical population of the present study consisted of all female nursing students of Rafsanjan University of Medical Sciences. The research sample consisted of 30 individuals selected by targeted sampling method and randomly divided into two experimental groups (15 people) and control (15 people). Perceived stress (2005) responded before and after the intervention. The experimental group underwent 8 minutes of 80-minute sessions (once a week) under the direction of Cabin Dabinchr('39')s mindfulness management (2000) and the control group did not receive any intervention. Subjectschr('39') scores were analyzed using mean, standard deviation and analysis of covariance using SPSS-22 software.

The findings showed that there was a difference between the scores of psychological distress in the pre-test (66.30±6.53) and post-test (89.88±7.12) (P <0.01). Also, a significant difference was observed in the perceived stress scores in the pre-test (28.31 ±4.46) and post-test (21.73 ± 5.24) in the experimental group after the intervention. This difference was not observed in the control group (P <0.01).

Mindfulness training is effective in increasing psychological hardship and perceived stress. Therefore, this type of training can be used to reduce the stress of nursing students.

Diagnosis of mental disorders and resilience of individuals during the epidemic of diseases is necessary for planning. The purpose of this study was to determine the resilience, stress, depression and anxiety of households in Anar city at the time of the outbreak of COVID-19 disease.

The present descriptive study was conducted among 453 households in Anar city (from Rafsanjan County). Data were gathered using questionnaires and in a web-based approach. Data were analyzed using independent t-tests, Tukey’s post hoc test and Spearman’s correlation coefficient.

The results showed that 251 (57.7%), 233 (51.4%) and 260 (57.3%) participants had levels of stress, anxiety and depression, respectively. The mean and standard deviation of resilience score was 37.55±19.18. There was a significant relationship between anxiety and level of education, job and age and also depression and job levels.

Due to the high prevalence of mental disorders and low resilience during the epidemic of the disease and its consequences, psychological interventions are recommended.

One of the problems of nursing students is the reduction of psychological hardship and academic self-efficacy. Study was conducted to evaluate the effectiveness of mindfulness training on psychological hardship and academic self-efficacy.

The method of this research was semi-experimental and pre-test-post-test method with control group. The statistical population of the present study consisted of all female nursing students of Rafsanjan University of Medical Sciences. The research sample consisted of 30 people selected by targeted sampling method and randomly divided into two experimental groups (15 people) and control (15 people) and responded to psychological hardship and academic self-efficacy questionnaire responded before and after the intervention. The experimental group underwent eight 80-minute sessions (once a week) for the treatment of mindfulness-centered management and the control group did not receive any intervention. Subjectschr('39') scores were analyzed using Chi-squar, T test and covariance analysis.

The results showed that the mean and standard deviation of psychological hardship in the pretest in the intervention and control groups were 76.30 ± 6.53 and 77.18 ± 6.54 and in the post-test of the intervention and control groups were 102.88 ± 7.7 and 76.68 ± 6.15. Also, the mean and standard deviation of academic self-efficacy in the pretest in the intervention and control groups were 65.55±5.74 and 66.33 ± 3.74 and in the post-test of the intervention and control groups were 82.82 ± 6.12 and 65.82 ± 3.61. Therefore, in the experimental group, the scores obtained were significantly different compared to the control group (p <0.05).

Mindfulness training is effective in increasing psychological hardship and academic self-efficacy. Therefore, this type of training can be used to reduce the stress of nursing students.

The structure of some families provides conditions for violence against women. Violence threatens the health and security of the family. The purpose of this study was to predict marital forgiveness based on emotional regulation, attachment to God, and religion-based coping strategies in women with experience of family violence.

This is a descriptive and correlational study. The statistical population included all women referring to counseling and psychotherapy centers in Tehran in 2018. A total of 300 people were selected by simple random sampling. The research instruments included marital forgiveness scale, cognitive-emotional adjustment scale, attachment to God's scale, and religious coping scale. Data were analyzed using descriptive statistics, correlation coefficient and regression analysis. In this study, all the ethical considerations have been observed and no conflict of interest was reported by the authors.

The results of the present study showed that emotional adjustment variables (P<0.05, r=0.61), attachment to God (P<0.05, r=0.48), and religion-based coping strategies (P<0.05, r=0.52) have a significant correlation with marital forgiveness in women experiencing domestic violence and can significantly predict 41.8 percent of the variance in marital forgiveness in these women (P<0.05).

Based on the results, it can be concluded that religion-based coping strategy, safe attachment to God, and adjustment of excitement affect the level of marital forgiveness. Therefore, in the plans developed by the authorities, there is a need to familiarize women experiencing domestic violence with Islamic-spiritual structures and emotional management.
