Method: Forty-seven depression patients referred to psychiatric outpatient clinic who were not on treatment and 47 normal healthy volunteers were enrolled in the study. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), the Hamilton Depression Rating Scale (HAM-D), and the Clinical Global Impression (CGI) Scale were administered to all participants. Peripheral blood samples were collected following a 12-hour fasting at the beginning and three months after the start of treatment. Serum apelin and nesfatin-1 levels were measured. Results: Of the 47 depression patients, 35 (74.5%) were females and 12 (25.5%) were males. Thirty-one (66%) of the 47 volunteers were females and 16 (34%) of them were males. Age, marital status, occupation and Body Mass Index (BMI) did not differ between the groups. Serum apelin level was significantly higher in the patient group than in the control group. There was no significant difference between the patient group and the control group in terms of serum nesfatin-1 levels. There was no significant difference in serum apelin and serum nesfatin-1 levels after 3 months of treatment. Conclusions: Serum apelin levels were significantly higher than healthy controls at the time of admission and there was no change in apelin levels after 3-months of treatment (antidepressant, antidepressant + electroconvulsive therapy, antidepressant + therapy) despite clinical recovery. Serum nesfatin-1 levels in the patient group were not different from the control group at the time of referral and at the end of 3 months treatment. There was no relationship between serum apelin level and BMI in our study. Serum nesfatin-1 level and BMI were correlated at the time of admission.

Therefore, the relationship between socioeconomic status and safety behaviors is not far-fetched. The present study aimed to investigate the effect of socioeconomic status on safety behavior in workers of the subway construction project in Qom, Iran. Materials and Methods: The present cross-sectional study was conducted on workers of the subway construction project in Qom in 2020. The sample size was determined by a census of 200 people based on the study criteria. Socioeconomic status and safety behavior questionnaires were subsequently completed for the participants. The data were extracted and analyzed by SPSS software (version 21) after completing the questionnaires. Results: The results of the study revealed no significant relationship between the level of education and safety behavior (P-value> 0.05); however, a significant relationship was observed between that and safety compliance (P-value= 0.006). No significant relationship was discovered between the type of employment and socioeconomic status (P-value=0.008). Also, No significant relationship was found between economic status with safety observation, participation, and behavior (P-value> 0.05). Conclusion: The results of the present study indicated no significant relationship between socioeconomic status and compliance, participation, and safety behavior of individuals. Organizational, cultural, and individual factors affect safety and safety behavior along with socioeconomic status. No relationship was observed between socioeconomic status and employee safety behavior which can be attributed to coverage of other factors that failed to be examined in this study.

Printing industry workers are involved in tasks that increase the risk of musculoskeletal discomforts. Therefore, the present study aimed to investigate the relationship of musculoskeletal discomforts with manual load lifting and workers' postures in a printing industry. Materials and Methods: In the current study, the prevalence of musculoskeletal discomforts among the workers in the printing industry was investigated using the Cornell questionnaire. Manual load lifting tasks in the industry were also assessed in three methods of Snook tables, WISHA, and KIM-LHC. Workers' postures were assessed using the REBA method. Data were analyzed using SPSS (version 22) through Mann-Whitney U test and Kruskal-Wallis non-parametric tests. Results: The results of the Cornell questionnaire showed that the most common complaints were related to pain in the lower extremities, including feet, legs, and knees. The comparison of the results of Cornell questionnaire and the results of WISHA method using Kruskal-Wallis test showed that the neck (P=0.016), right shoulder (P=0.028), left shoulder (P=0.031), back (P=0.022), and right forearm (P=0.045) had a significant relationship with WISHA results. Conclusion: The association of the prevalence of some musculoskeletal discomforts with the results of WISHA method indicated the superiority of this method to KIM-LHC and Snook tables methods for the assessment of manual load lifting tasks in printing industries. Moreover, the lack of correlation between musculoskeletal discomforts and posture assessment using the REBA method revealed that the reasons for the prevalence of these discomforts in the industry should be sought in cases other than inappropriate postures.

Also, it is intended to analyze the role of individuals and job characteristics on using earplugs or earmuffs. In this study, workers participated from 16 printing industries located in five areas of Tehran province and completed the questionnaire knowledge, attitude, and practice (KAP) about hearing conservation. Noise measurement was performed based on participants' tasks. With increasing attitude, practice improved (P = 0.001). The results revealed that positive attitude led to improved practice of workers in hearing conservation (r = 0.172; P < 0.001), and with increasing knowledge, negative attitude diminished (P=0.014). The results indicated that awareness is correlated with attitude, and attitude could directly affect the behavior. Thus, awareness as an intermediate or primary factor might play an important role in developing...

METHODS Considering the 135 fall accidents collected between 2013 and 2018 from fifteen residential construction projects, 70 factors and sub-factors affecting the occurrence of construction falls were determined based on the safety experts' opinions. Then, questionnaires based on the former and the latter were distributed among 10 occupational health and safety specialists to determine the effectiveness of the factors. The interactions and important degree of each factor are specified, using DEMATEL-ANP approach. RESULTS Findings showed that organizational factors and their sub-factors have the greatest impact on construction falls and were considered as causal variables (D-R>0), while individual and environmental factors were considered as the effect variables (D-R<0). The results of prioritization using the ANP method showed that the work platform altitude, psychological/occupational stresses, and interactions were ranked as the first through third priorities affecting the falls, respectively. CONCLUSIONS It is necessary to implement a systematic strategy to reduce the unsafe conditions in construction projects and to pay more attention to organizational factors.

After determining the subjects of the study, the questionnaires of safety behavior and job security were completed for subjects. Also, the salary of subjects was determined. Structural equation modeling was used in smart PLS software to modeling. The results revealed that job security had a direct and significant correlation with safety compliance, safety participation, and safety behavior (P<0.001). The salary as a moderator had a positive and significant effect on the relationship between job security and safety behavior (P<0.05). Generally, it can be deduced that job security had a positive impact on safe behaviors, and the salary as a moderator enhanced this impact. To improve safety behavior in workplace, employers should increase the job security of workers.

The results revealed that positive attitude led to improved practice of workers in hearing conservation (r = 0.172; P < 0.001), and with increasing knowledge, negative attitude diminished (P=0.014). The results indicated that awareness is correlated with attitude, and attitude could directly affect the behavior. Thus, awareness as an intermediate or primary factor might play an important role in developing...

METHODS Considering the 135 fall accidents collected between 2013 and 2018 from fifteen residential construction projects, 70 factors and sub-factors affecting the occurrence of construction falls were determined based on the safety experts' opinions. Then, questionnaires based on the former and the latter were distributed among 10 occupational health and safety specialists to determine the effectiveness of the factors. The interactions and important degree of each factor are specified, using DEMATEL-ANP approach. RESULTS Findings showed that organizational factors and their sub-factors have the greatest impact on construction falls and were considered as causal variables (D-R>0), while individual and environmental factors were considered as the effect variables (D-R<0). The results of prioritization using the ANP method showed that the work platform altitude, psychological/occupational stresses, and interactions were ranked as the first through third priorities affecting the falls, respectively. CONCLUSIONS It is necessary to implement a systematic strategy to reduce the unsafe conditions in construction projects and to pay more attention to organizational factors.

After determining the subjects of the study, the questionnaires of safety behavior and job security were completed for subjects. Also, the salary of subjects was determined. Structural equation modeling was used in smart PLS software to modeling. The results revealed that job security had a direct and significant correlation with safety compliance, safety participation, and safety behavior (P<0.001). The salary as a moderator had a positive and significant effect on the relationship between job security and safety behavior (P<0.05). Generally, it can be deduced that job security had a positive impact on safe behaviors, and the salary as a moderator enhanced this impact. To improve safety behavior in workplace, employers should increase the job security of workers.

Job stress is the harmful responses that result from a mismatch between onechr('39')s abilities and knowledge with job pressures and demands. Stress is one of the most important and effective factors in disturbing peoplechr('39')s health, that makes a person unable to perform his or her individual, family and social duties and commitments optimally. Public health means complete physical, mental and social welfare (Not just lack of illness and disability). One of the most common disorders in general and occupational groups is mental disorders. The most important signs and symptoms of mental health include self-reliance, independence, the ability to cope with others, the ability to accept responsibility and the duty, to express love and affection, the ability to endure failure, and so on. Manpower is one of the most important re...

This study will determine the role of different machine learning components such as feature selection and classification to determine suitable factors for safety construction signs comprehensibility. A total of 2310 participants were requested to guess the meaning of 20 construction safety signs (four items for each of the mandatory, prohibition, emergency, warning, and firefighting signs) using the open-ended method. Moreover, the participants were asked to rate the cognitive design features of each sign in terms of familiarity, concreteness, simplicity, meaningfulness, and semantic closeness on a 0–100 rating scale. Subsequently, all eight features (age, experience, education level, familiarity, concreteness, meaningfulness, semantic closeness, and simplicity) were used for classification....

In this descriptive-analytical study, the relationship between organizational safety culture, job stress and satisfaction has been investigated to have a better understanding of the effect of this organizational factor on employee job stress and satisfaction. Three valid tools, including the Safety culture questionnaire, standard job stress questionnaire (JSQ), and Standard Minnesota Job Satisfaction Questionnaire, were used. The study population consisted of 210 workers working in 13 production halls of an automotive industry who were selected by a simple random sampling method. After data collecting, SPSS software version 22 was used for data analysis, and AMOS software version 24 was used for confirmatory factor analysis. The results show a significant relationship between trained and untrained groups and safety culture (p = 0.002), job stress and education level (p ...
