Pulmonary function testing in cement transport workers at incheh borun border, Northeast of Iran

Background: The aim of this study was to evaluate respiratory problems via pulmonary function testing in cement transport workers at Incheh Borun border in northeast of Iran in 2016. Methods: The study was conducted on 358 male workers. All subjects were evaluated for respiratory symptoms via pulmonary function testing and completion of the American Thoracic Society questionnaire. Results: Mean age of workers was 34.8±12.87 yr (age range 16-79 yr). Mean duration of employment was 6.1±4.36 yr. Most workers (75.4) were illiterate or had elementary education. In addition, 56 (15.6) subjects were smokers. Only three individuals (0.3) had obstructive pattern. There was a significant relationship between age of workers and frequency of respiratory problems (P<0.05). Conclusion: It is necessary to educate the workers about the health and safety regulations and use of personal protective equipment in workplace. In addition, periodic evaluation of respiratory function could help protect workers from developing occupational diseases. © 2019, Iranian Journal of Public Health. All rights reserved

The Epidemiology of Aggression and Associated Factors among Iranian Adult Population: A National survey

Background: This survey was conducted to determine the level of aggression among the Iranian adult population and underlying predisposing factors. Study design: A cross-sectional study. Methods: This cross-sectional study included 10,957 participants, involving 23 out of the 31 provinces of Iran in 2019. The outcome of interest was aggression, evaluated by the Buss & Perry aggression questionnaire. The association between aggression and 34 demographic, behavioral, social, and cultural characteristics was assessed using simple and multiple linear regression. Results: The overall mean (SD) score of aggression was 77.10 (22.53). Based on the severity of aggression, the participants were categorized into four groups as follows: 2,464 (23.1) nonaggressive, 4,692 (43.9) mild, 3,071 (28.8) moderate, and 454 (4.2) severe aggressive. Aggression was more likely to occur in people with the following characteristics: younger ages, having several siblings, lower ranks of birth, having an intimate friend of the opposite sex, having an aggressive father/mother, history of parental divorce, interest in watching action/porn movies, listening to music, history of escape from home/school, using neuropsychiatric drugs, using illicit drugs, history of suicidal thoughts/attempt, and family conflict and hostility. Aggression was less likely to occur with the following characteristics: reading, regular physical exercise, the ability to control anger, regular prayer, adherence to avoid lying, respect to other people's rights, sexual satisfaction, and attachment to parents. Conclusions: A majority of the population has some degree of aggression. Aggression is a multifactorial behavior corresponding with several demographical, social, cultural, and religious factors, some of which back to early childhood events

Mapping the global influence of published research on industry and innovation

Public research is critical to the economy and society. However, tangible economic and social impact only occurs when research outputs are combined, used and reused with other elements and capabilities, to deliver a product, practice, or service. Assessing the context and influence of scholarship during the dynamic process of innovation rather than measuring ex post impact, may improve performance. With this aim, we integrated and interconnected scholarly citations with global patent literature, and here we offer new tools enabling diverse stakeholders to freely evaluate the influence published research has on the generation and potential use of inventions as reflected by the patent system. We outline an evolving toolkit, Lens Influence Mapping, that allows assessment of individual scholarly works and aggregated outputs of authors for influence on industry and enterprise as measured by citations within patents. This performance measure, applied at many levels and normalized by either research disciplines or technology fields of use, may expose and highlight institutional strength and practices, and guide their future partnership
