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

Introduction: the quality of life of nurses and nurse aides is under the influence of various factors including the occupational ones, which affect the quality of their services. The purpose of this research was to investigate the occupational and demographic factors effective on the quality of life of nurses and nurse aides working in teaching hospitals affiliated to Kerman University of Medical Sciences.

Methods: the present research was a cross-sectional one conducted in 2014 on 620 nurses and nurse aides. Simple random sampling method was utilized. The data were collected via the World Health Organization Quality of Life short form (questionnaire). Shift working, having a second job, marital status, length of marriage and having a shift working spouse were the independent variables of this study. Data were analyzed in SPSS 18 software using analysis of variance (ANOVA), Pearson’s correlation coefficient, independent t and linear regression statistical tests.

Results: the average age, length of marriage and work experience in hospital were 32.81 ± 7.84, 10.61 ± 7.30 and 10.29 ± 7.68, respectively. The number of children, having a second job, satisfaction from the hours spent with family, and belief in the effect of night work on family life were factors effective on quality of life (P > 0.05). The highest relationship of quality of life was with environmental health (r = 0.87, P = 0.001) and the lowest was with social health (r = 0.75, P = 0.002).

Conclusions: Avoiding to have a second job, scientific planning of shift work schedules and trainings relevant to life skills in shift workers would help improve the quality of life of nurses and nurse aides.

Volume 8, Issue 2 (Iranian Journal of Ergonomics 2020)
Abstract
Background and Aim:  Accurate and rapid measurement of cardiorespiratory system performance by estimation methods regardless of basic physiological fitness level, geographical environment, culture and nutrition is of paramount importance. The purpose of this study was to design linear regression equations to estimate the aerobic capacity of healthy adolescent boys without the use of sport tests and validation of this equations.
Methods: In the present semi-experimental study, 156 healthy adolescent boys aged 13 to 17 years with a mean body mass index of 21.43 ± 4.5 Kg / m2 were selected by purposive sampling method. To design the non-sport equation for estimating maximum oxygen consumption (VO2peak), a multiple regression linear model and Pearson correlation were used to validate the equations.
Results: Significant correlations were observed between the measured VO2peak and the anthropometric and physiological variables (R=0.122 - 0.799, P<0.001). Also, a valid non-exercise linear equation for boys' VO2peak prediction was designed with variables such as age, BMI and resting heart rate (SEE = 3.59 mL/kg/min, R2 = 0.712, P<0.001). The estimated VO2peak from equations had a significant correlation with the obtained criterion value. (R = 0.707 – 0.730, P<0.01).
Conclusion: According to the results of the present study, it is possible to use aerobic capacity estimation equations, is a simple, accurate, safe tool in assessing the baseline cardiorespiratory fitness (VO2peak). The use of non-Exercise equations in the planning of exercise in large populations of adolescent boys and even as a daily clinical practice in the elderly and heart patients with the goals of promoting health, cardiovascular health, preventive actions is very important.

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.
