Abstract
Introduction:
The maximum aerobic capacity (VO2-max) can be used to assess the cardio-respiratory
condition and fit the physiological characteristics of workers to the work.
This study was conducted to determine the correlation between the two methods
of estimating the maximum aerobic capacity and its affecting factors among
students of Shiraz University of Medical Sciences.
Materials
and Methods: In this cross-sectional study, 104 students (54 males and 50
females) participated voluntarily (age ranged from 18 to 28 years). The
subjects were assessed by step test according to Åstrand and ACSM protocols.
The data collecting tool was a questionnaire including separate sections of
demographic (age, sex, etc.), anthropometric (height, weight and BMI) and
physiological (VO2-max) characteristics.
Results:
The results revealed that the maximum aerobic capacity estimated from Åstrand
and ACSM protocols were 3.21 (0.825) and 3.13 (0.707) l.min-1, respectively.
Pearson correlation test showed high correlation between estimated maximum
aerobic capacity via two protocols of Åstrand and ACSM (r=0.958). Meanwhile,
there were significant associations among maximum aerobic capacity with weight,
height, BMI and the number of hours of exercise per week.
Conclusion: The two
methods for estimating the maximum aerobic capacity (Åstrand and ACSM) were
highly correlated. Variables such as weight, height, BMI, and number of hours
of exercise per week can be named as effective factors on VO2-m

Abstract
Introduction: In an
educational environment, the quality of vision is integral to educational
progress. Creating visual comfort and increasing efficiency and the desire to
study are among the benefits of adjusting the lighting in classrooms and
preventing visual impairment in the students. The present study was conducted
to evaluate the degree of internal lighting in girls' schools across Hamadan in
2006 and 2014 so as to help identify their potential problems.
Materials and
Methods: The present study was conducted in girls' schools across Hamadan on two
different occasions –in 2006 and 2014. On each occasion, the average general
and local lighting on the classroom blackboards were measured by the
recommended methods of the Illuminating Engineering Society of North America on
non-sunny days using a Lux Meter and were then compared to the standard limits
recommended in the Health and Safety Code of schools and by the Illuminating
Engineering Society of North America. In addition to the degree of lighting,
certain quality assessment criteria were assessed, including the lighting
layout, lamp maintenance, contrast, internal surface cleaning, lighting system
maintenance, type of lamps and technical suitability of the design.
Results: Taking the
criteria for favorable lighting conditions into account, less than 25% of the
sites examined had favorable lighting on both occasions in 2006, only 16% of
the classes had favorable general lighting and in 2014, the degree of lighting
fell to an unacceptable range in all classes and only 6% of the entire
classroom were covered by a standard degree of local lighting on the
blackboard. The results also show that surface reflection coefficients are
within the desirable range.
Conclusion: The lack of
favorable general and local lighting on the blackboard at schools in 2014 and
its comparison with the results of the 2006 lighting assessment indicate that
providing standard lighting is still a problem for schools. Improper lighting
layouts and the use of incandescents or inappropriate light bulbs are among the
major causes of poor lighting conditions in girls' school across Hamadan.

Abstract
Introduction: Sleep disorder is very common among employees and is considered as one of the crucial health problems. Sleep disorders have a negative impact on job performance. The present study was regarding the relationship of sleep quality, sleepiness and sickness absence.
Methods: This cross-sectional study was conducted on 400 employees of a gas company through random sampling. The study data were collected using the Pittsburg Sleep Quality Index (PSQI) and the Karolinska Sleepiness Scale (KSS). Mann-Whitney U test and Spearman’s correlation coefficient were applied for data analysis.
Results: While 43.2% of the participants enjoyed satisfactory sleep quality, 56.8% had unsatisfactory sleep quality. Statistical tests indicated a significant difference in sickness absence of the personnel with good and poor sleep qualities (P = 0.0001). Spearman’s correlation coefficient (ρ = 0.777) indicated a statistically significant correlation between sleepiness index and sickness absence (P = 0.0001).
Conclusions: The results showed a strong positive correlation in sleep quality, sleepiness index of the personnel and sickness absence; i.e. along with decline in sleep quality and incline in sleepiness, the personnel’s sickness absence increased.

Abstract
Background and Objectives: Factors affecting one's job performance include job stress, job calling and burnout. The purpose of this study was to determine the causal relationship between job stressors, job calling and job burnout among employees of Hamadan University of Medical Sciences.
Methods: This descriptive-analytical cross-sectional study was performed on 378 non-faculty members of Hamadan University of Medical Sciences. Data were collected using Maslach Burnout Inventory, Job Stress Questionnaire (HSE-Q) and Dik's job calling. To investigate the relationship between variables, Structural Equation Modeling (SEM) method was used in AMOS version 24 software.
Results: The mean age of participants was 38.93 years. The components of job stressors and job calling had a positive and significant correlation with the components of job burnout (P<0.05). The measurement model was acceptable with the collected data. Job stressors indirectly and mediate the dimensions of presence and search of job calling are related to job burnout of medical university employees. The sum of squares of multiple correlations for job burnout variable was 0.56. This finding indicated that occupational stressors and job calling account for 52% of the variance in burnout.
Conclusion: Given the detrimental effects of burnout on employees, it is suggested that authorities reduce stressors such as the psychological and physical needs of the workplace, lack of support, job insecurity, and job calling.

Abstract
Background and Aim: A good work environment is a place where one can feel relaxed and focused. In the field of environmental psychology, color is one of the environmental factors that greatly influence human perception and behavior. The purpose of this systematic review study was to investigate the effect of color on work environment.
Methods: This article is a systematic review study. Full-text and English-language articles published in PubMed, Scopus, Science Direct, Google Scholar were searched using the following keywords: Color perception, color ergonomics, color psychology, color effect, mental health and Workplace. The search was without time limit, and 45 eligible articles were reviewed.
Results: Initially, 262 articles were identified from different databases. Among them, 93 articles met the criteria for entering the study. After that, 48 articles were removed from the study due to lack of experimental studies and 45 articles were selected for final review. A total of 18 studies focused on color priority, 25 studies on mood and emotions, 6 studies on health outcomes, and 19 studies on the effect of workplace color on work-related outcomes. The results showed that color has a significant effect on emotions (eg mood), well-being (eg stress, comfort, well-being) and performance (eg productivity, creativity).
Conclusion: Workplace color should be considered as one of the main ways to promote the (mental and physical) health of individuals.

Abstract
Background and Objectives: One of the most important aspects of ergonomics is physiologic balance between human characteristics and their jobs. This study aimed to investigate the physiological characteristics of janitor, safety guard and facility workers of a work organization and determine their physiological fit.
Methods: A total of 70 staff were evaluated using Queen's college step test, N20 body composition analyzer, SECA scale, RS800CX Polar pacemaker. Descriptive statistics and analytical tests including ANOVA and Pearson correlation were used. The data was analyzed using SPSS 20.
Results: Body Mass Index (BMI) and fat percentage (Fat%) of employees were beyond the optimal range, but Waist to Hip Ratio (WHR) were in the range. Also, the average Maximum Volume of Oxygen consumption (VO2max) were 42/1±62/33 mL/kg/min and the average of working capacity (maximum Physical Work Capacity: PWCmax) were 16/63±4/46 kcal/min.
Conclusion: The results indicated that the level of some physical characteristics is inappropriate, physical fitness is poor and individual capabilities and job requirements are not in balance. Using standardized recruitment tests, providing the possibility of sports activities (by organizations) and finding integrated indicators that simultaneously take into account the physical, mental, social and environmental capabilities of individuals to determine work capacity (by researchers), can be facilitating steps to establish an ergonomic balance in the workplace.

Abstract
Objective: The emergence of presenteeism in the organizational environment can have significant negative consequences. A key point in this regard is that the quality of leader-member exchange can influence the increase or decrease of presenteeism. Additionally, organizational commitment has a meaningful relationship with presenteeism. Therefore, the present study aims to analyze the relationship between leader-member exchange and organizational presenteeism among university employees through the mediating role of organizational commitment.
Method: To achieve this goal, a descriptive-correlational method was used based on structural equation modeling. The research population consisted of all 145 male and female employees of Malayer University, and due to their small number, a census method was used to select the samples. For data collection in this study, three questionnaires were used: Leader-Member Exchange, Organizational Presenteeism, and Organizational Commitment. For data analysis, descriptive statistics and inferential statistics were used in two software packages, SPSS version 23 and SMART PLS version 3.
Results: The research findings showed that leader-member exchange has a significant negative path coefficient (-0.271) on organizational presenteeism, leader-member exchange has a significant positive path coefficient (0.585) on organizational commitment, and organizational commitment has a significant negative path coefficient (-0.286) on organizational presenteeism, all at the 0.01 level of significance. Additionally, the indirect effect of leader-member exchange on organizational presenteeism through the mediating role of organizational commitment is significant, with a Sobel test statistic of 2.627 at the 0.05 level of significance.
Conclusion: Overall, the results of this study indicate that improving leader-member exchange as well as increasing organizational commitment can lead to a reduction in organizational presenteeism in an academic environment.
