Rostam Golmohammadi, Mohammad Hajiakbari, Rashid Heydari Moghadam, Razie Zare, Seyede Khadije Hoseini, Samane Karami,
Volume 2, Issue 4 (3-2015)
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.

Mohammad Amin Mououdi, Seyed Noroddin Mousavinasab, Seyed Mohammad Reza Gramian, Jafar Akbari,
Volume 4, Issue 1 (6-2016)
Abstract

Introduction: Introduction: Inappropriate sizes of school furniture and the deformation of children’s bodies is one of the issues of concern in the world. The aim of this study was the evaluation of anthropometry of primary students aged 6-12 years in Mazandaran, Iran and the design of school furniture based on the anthropometric criteria of the students.

Methods: In this cross-sectional study, 18 anthropometric dimensions of 2336 boys and girls aged 6-12 years in 2014-2015 were measured. To collect data, anthropometric chair, camera and camera stand, and Anthropometric photo graphical software were used. After determining the anthropometric dimensions, ergonomic school furniture was designed.

Results: Average, minimum, maximum, standard deviation, median and percentile value of 2.5 to 97.5 of the anthropometric dimensions of students were calculated. The results showed that gender had no effect on the popliteal height in the age groups of 6 to 7 and 7 to 8, but age had effects on popliteal height (P < 0.001). In the age groups of 8 to 9 and 9 to 10 years and also the age groups of 10 to 11 and 11 to 12 years both gender and age had effects on popliteal height (P < 0.001).

Conclusions: The results showed that by eliminating the effects of gender, 16.2 mm popliteal height increased per year. It was also found that after eliminating the effects of age, popliteal height increased 20.39 mm more in girls than in boys. Until the age of puberty, the anthropometric dimensions in girls increased more than in boys. The dimensions of ergonomics tables and chairs for students were designed in three sizes.

Saeed Ilbeigi, Aboozar Kabootari, Mohamadesmaiel Afzalpour, Hossein Farzaneh,
Volume 5, Issue 3 (11-2017)
Abstract
Background: Undesirable sit-up and deviation from desirable status is one of the factors affecting the health of students in the classroom. The purpose of this study was to evaluate the relationship between posture and musculoskeletal pain in boys 9 to 13 years old.
Methods: In this correlation study, the population consisted of all boy students in the primary city of Birjand. 60 students were selected as a sample group based on random-cluster method. Two video cameras were recorded 30 minutes of sitting position for every student. The anthropometric characteristics of subjects including height, weight, etc., were measured with a standard tool. The back and neck pain were collected using a modified Nordic questionnaire. Moreover, the kinovea software was used to analyze the flexion and rotation angle during sitting. The statistical calculations were applied by Kolmogorov-Smirnov normality test. The ETA correlation coefficient also was used to identify the relationship between variables. All statistical calculations performed using SPSS version 21.
Results: The result indicated significant relationship between bending and rotation angles with both neck and back pain (P≤0.05). Therefore it would be noticed that improper sitting can be accounted as a cause of muscle-skeletal pain in boy students based on bad postures during sitting.
Conclusion: According to the results, the posture of students while sitting in class is inadequate and harmful. Thus performing some intervention and education for students is recommended.

Volume 11, Issue 1 (5-2023)
Abstract
Objectives: School counselors are responsible for addressing academic, personal/social, and career development needs through the design, implementation, evaluation, and enhancement of a comprehensive school counseling program that results in improved student achievement. Therefore The aim of this research was to investigate the effectiveness of the intervention based on the empowerment model on the job performance of school counselors.
Methods: The method of the current research was a mixed sequential exploratory type. For this purpose, a semi-experimental method with a pre-test-post-test design with a control group was used to check the effectiveness of the training package. The statistical population of the research included all the school counselors working in the first secondary school of Ardabil city (areas 1 and 2) in the academic year 2021-2022, among them based on the cut-off point of the school counselor occupational performance scale (score 86) and taking into account the entry criteria For the research, 30 people were selected as a sample by random sampling method and according to the results of the pre-test, they were randomly replaced in two experimental and control groups (15 people in each group). The members of the experimental group received the desired educational content in one introductory session and 11 sessions of 120 minutes, while the members of the control group did not receive any intervention. The follow-up test was also done after 3 months. The obtained data were analyzed using spss software and multivariate analysis of covariance test.
Results: The results showed that the intervention based on empowerment has a positive and significant effect on the job performance components of school counselors. This means that school counselors as a result of participating in training sessions based on the empowerment model, in the dimensions of knowledge (F = 0.20 and P = 0.001), skills (F = 0.69 and P = 0.001) and attitude and behavior (F=0.47 and P=0.001) had a positive and significant performance.
Conclusion: Teaching the content related to the empowerment model is an effective way to improve the performance of school counselors.

Volume 12, Issue 3 (12-2024)
Abstract
Objectives: Various factors, including a lack of attention to the adaptation of educational spaces, can significantly impact the quality of education. Consequently, this study aims to comprehensively review and analyze all research conducted on school ergonomics in Iran.
Methods: A bilingual search was conducted in this study utilizing Persian keywords such as "Student," "Elementary, middle or high school," and "Physical, environmental, and general ergonomics," along with their Latin equivalents. This search was performed across databases, including Google Scholar, PubMed, Web of Science, and Scopus, covering the period from the inception of research in Iran until 2024. Subsequently, articles relevant to the topic were collected and examined according to the established criteria.
Results: Among the identified articles, only 30 were recognized as relevant to the study's objectives, focusing on physical, environmental, and general ergonomics. A comparison of these studies revealed an upward trend in musculoskeletal disorders, with many of these issues linked to ergonomic problems in schools, including the mismatch between students' body dimensions and the desks and chairs used, as well as improper carrying of school bags.
Conclusion: The poor ergonomic conditions in Iranian schools have led to an increase in musculoskeletal disorders among students. It is vital to evaluate these schools based on ergonomic standards and implement necessary enhancements. Furthermore, it is important to raise students' awareness about proper task performance and appropriate backpack usage.
