Abstract
Background: Nickel is a toxic metal used as a pigment in ceramics industries. The purpose of this study was to assess inhalation exposure to nickel in the breathing zone of glazers and non-exposed group of workers. We also compared pulmonary function between ceramic glazers and the non-exposed group. Methods: In this cross-sectional study, 49 glazers and 55 office workers were investigated. Air sampling in the breathing zone of each glazer was taken on a cellulose ester membrane filter with 37-mm diameter. The samples were then analyzed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). All the participants were required to fill out questionnaires on descriptive information. The parameters of pulmonary function were measured for both exposed and non-exposed participants. Results: The mean nickel concentration in the breathing zone of glazers was 0.09 mg/m3. Glazers had a significantly lower parameters of pulmonary function than office workers (p<0.05). Level of nickel was significantly higher in tile glazers in comparison with pottery glazers. Conclusion: In factories where local or general control is not feasible, workers must use personal protective equipments. Workers also should not be allowed to eat or smoke in the workplaces with toxic materials.

Abstract
Background: The spread of coronavirus (Covid-19) had many psychological consequences. Nurses experience anxiety due to their professional duties. Considering the importance of mental health and caring behaviors in nurses, the present study was conducted to investigate Covid-19 anxiety in nurses and its relationship with cognitive flexibility. Method: The present study was conducted on 100 nurses of a selected hospital in 2021. Data collection tools included demographic questionnaire, Corona Disease Anxiety Scale (CDAS) and Cognitive Flexibility Inventory (CFI). Data analysis was performed through version 22 of SPSS software using Mann-Whitney, Kruskal–Wallis, independent sample t-test, one-way ANOVA and correlation tests. Results: The mean of cognitive flexibility was 96.68 (13.72). The median of Covid-19 disease anxiety was equal to 8 (9). Accordingly, the results of data analysis showed that there was no significant relationship between demographic variables and covid-19 anxiety (P>0.05). Furthermore, no significant relationship was found between cognitive flexibility and covid-19 anxiety (P>0.05). Conclusion: In this study, cognitive flexibility had no significant effect on Coronavirus disease anxiety. Considering the presentation of contradictory results in this field, authors suggest that a similar study be conducted with a larger sample size and different variables be taken into account.
