Abstract
Introduction: Working with Visual Display Terminals (VDTs) can be associated with visual complaints particularly visual fatigue and symptoms including headache, disruption in continuing the work and ocular disorders. The objective of the present study was to determine the prevalence of visual fatigue and its related risk factors in computer users of Kermanshah University of Medical Sciences in 2013.
Materials and Methods: This descriptive-analytical study was achieved on 260 computer users. The data were collected by Visual Fatigue, demographic and job questionnaires. For data analysis, Spearman, Mann-Whitney and Kruskal-Wallis tests were used.
Results: The mean (SD) age of the users was 36.74 (7.74) and daily working time with VDTs was 5.85 (2.28) hours. Visual fatigue score was 2.99 (1.97), so that 32.3% of computer users had severe eye fatigue. Meanwhile, 45.4, 21.9, 32.7 and 46.2 percentage of users suffered severely from eye strain, visual impairment, eye-surface disorder and extra-ocular problems. Visual fatigue incidence and its compliments were significantly increased with increasing of age, work experience and daily working hours with computer (p<0.05). Visual fatigue was higher in users wearing glasses than those not wearing glasses (p<0.001) and was lower in monitor to window angle of 90º than two other monitor to window positions of 0º (p=0.041) and 180º (p=0.036).
Conclusion: The prevalence of visual fatigue among computer users was very high. Visual fatigue and its serious consequences can be prevented by applying the principles of ergonomics such as regular and short breaks, looking at distant objects, blinking regularly and reducing the direct and indirect glares.

Abstract
Background: Nurses’ Burnout can lead to increasing absenteeism and also decreasing energy and quality of service that provided by them. The aim of this study was to determine the prevalence of occupational burnout and its related factors among nurses of a hospital in Kermanshah city in 2013.
Materials and Methods: In this cross-sectional and descriptive-analytical study 189 nurses were selected randomly. Data were collected by demographic questionnaire and Maslach Burnout Inventory (MBI). The gathered data were analyzed by Pearson, Independent T-test and ANOVA in statistical level of p≤0.05.
Results: Mean score of occupational burnout was 61.89. 39.2% nurses reported high emotional exhaustion, 37.6% high depersonalization and 73.5% of them had low personal accomplishment. There were statistical relationship between emotional exhaustion with employment status (p=0.015) and educational degree (p=0.041), between depersonalization with employment status (p=0.022) and working shift (p=0.023), and also between personal accomplishment with age (p=0.010), working experience (p=0.002) and shift working (p=0.045).
Conclusion: The level of nurses’ occupational burnout was average to high. The causes may be high workload, unsafe and boring work environment and high stress. It can be increased the commitment, positive sense to work and personal accomplishment can be reinforced by correct management of human resources including the determination of duties and strategies according to nurses’ ability, new approaches for encouragement and motivation as well as running stress management workshops.

Abstract
Introduction: Job involvement is defined as one’s psychological dependence on his/her job. Employees with high job involvement
pay more attention to their job. The present study aimed to determine the relationship between teachers’
job involvement and demographic characteristics in Kermanshah (Iran) secondary
schools during 2013.
Materials and Methods: This cross-sectional study was
performed on 211 teachers (161 male and 50 female). Data were collected using
the Job Involvement Scale. The collected data were analyzed using Spearman’s
correlation coefficient, independent t-test, and analysis of variance (ANOVA).
P values less than 0.05 were considered significant.
Results: The teachers’ mean age and work experience were 32.21 and
8.49 years, respectively. Low, moderate, and high levels of job involvement were
detected in 22.3%, 54.5%, and 23.2% of the teachers, respectively. Job
involvement was significantly higher in married teachers than single subjects
(p = 0.027). Moreover, teachers without a second job had higher job involvement
than those with a second job (p = 0.006). There were no statistical
correlations between job involvement and age, sex, work experience, or level of
education.
Conclusion: The participating teachers
generally had low-moderate levels of job involvement. Low salary, working
multiple jobs, and low social prestige were mostly responsible for such low
levels of job involvement. Therefore, increasing teachers’ salary, providing
teachers with special facilities (e.g. low-interest loans), and developing a system
for teachers’ promotion (similar to that existing for faculty members) can be
effective in increasing job involvement among teachers

Abstract
Objectives: A significant indicators of progress and development is the publication of books within any scientific domain. Ergonomics, a critical field associated with human and occupational health, contributes to enhancing productivity and the health level of employees. The present study aims to investigate the state of production and publication of ergonomics books in Iran.
Methods: The current study employed a descriptive approach and content analysis with a bibliometric perspective. The research population encompaased all ergonomics books registered on the National Library website. To access relevant books, searches were conducted without temporal limitations using keywords such as ergonomics, human factors engineering, and other related terms. The collected data were then entered into a pre-designed form in Excel software and, in the final stage, were analyzed using descriptive statistics.
Results: In total, 313 book titles in the field of ergonomics have been published between the years 1989 to 2023, indicating an increasing trend in the publication of books in this area. The highest frequency was for authored books, accounting for 78.27 percent of the publications. Mohammad Amin Mououdi, Majid Motamedzadeh, and Alireza Choobineh were the most active authors in this field. The subject areas of ergonomics principles and application, occupational ergonomics, and human factors engineering had the highest frequency. Fanavaran publications held the highest rank among all publishers. In total, 38 book titles reached multiple editions.
Conclusion: The results of the current study signify an upward trend in book publication within the field of ergonomics in Iran. However, there is a need for more attention from authors in some specializations of this science, including occupational biomechanics, urban ergonomics, ergonomics in domestic settings, and ergonomics for children. Additionally, there is a notable lack of focus on the publication of electronic books in this scientific field. Therefore, to give more consideration to the advantages of electronic books and consider their publication.
