Background and Aim: Job enrichment is a method that has been used to increase employee satisfaction and work motivation. The Hackman and Oldham job characteristics model (1976) has served as the foundation for many job enrichment efforts. In particular, a considerable amount of research has been devoted to the study of the job characteristics-job satisfaction relations. Te purpose of this study was to statistically determine the relation between job characteristics and job satisfaction among employees of hospitals affiliated to Tehran University of Medical Sciences (TUMS) in 2007.
Materials and Methods: This study was a cross-sectional one, including 6 TUMS-affiliated hospitals-Emam, Shariati, Baharlo, Ziaeian, Madaen and Azadi. The sample size was 400, consisting of 200 administrative employees (50%), 151 nurses (38%) and 49 physicians (12%). The random sampling and stratified proportional sampling methods were used to select the hospitals and interviewees, respectively. Two questionnaires were developed and used to identify job characteristics and job satisfaction: 1) job diagnostics surveys (JDS) and 2) Hertzberg's job satisfaction questionnaire. The reliability of the questionnaires was ascertained by test-retest using the Pearson correlation coefficient (r = 0.88). Linear-by-linear association and ordinal logistics regression analysis were used for analyzing the data gathered.
Results:The relations between the Motivational Potential Score (MPS) and job characteristics (except for feedback) with job satisfaction were statistically significant (p<0.05). Task identity was the most effective determinant of job satisfaction.
Conclusion: It appears that all the job characteristics (except feedback) are important determinants of job satisfaction of the hospital employees. Although the work environment is in need of restructuring, it is important to note, from a positive perspective, that the job characteristics discussed in this study are readily amenable to change job satisfaction at the organizational level.

  Background and Aim: Physical inactivity is one of the 10 leading causes of mortality and disability. This study aimed to investigate the effect of e-learning on physical activity and body mass index (BMI) of female-employees.

Materials and Methods: In this semi-experimental interventional study, 120 female-employees of Tehran University of Medical Sciences were selected randomly and assigned to a case or control group. Data were collected using a demographic and an international physical activity questionnaire. Pre-test and post-test questionnaires were completed by the case and control subjects prior to, and 2 months after the final phase of, the intervention. The intervention included virtual education through short message service (SMS), email messages or messages via intanet, and educational films for a period of 16 weeks. SPSS-17 was used to analyze the data, the statistical tests being Chi-square, independent and paired-t, and Fisher's exact tests.

  Results: The mean age of the participants was 41 and 39 years in the case and control group, respectively. Most of them held a bachelor's degree and were married with 1 or 2 children. After the intervention, the mean score of physical activity in the intervention group increased significantly as compared with the control value (p<0.001). However, the intervention did not produce any change in the mean BMI of the case in comparison with the control group (p=0.119), although it brought about a statistically significant reduction in the initial BMI (p<0.001).

  Conclusion: Web-based education, SMS and multi-media messages can increase physical activity in female-employees and might prevent illnesses caused by physical inativity.

Background and Aim: As a crisis, the Covid-19 disease affected all aspects of people's lives, especially the occupational aspect.  Bank employees were more under pressure due to the type of service they provided to the public. The aim of this study was to analyze the challenges affecting the job efficiency of some of the Bank Melli Iran personnel during the Covid-19 pandemic.
Materials and Methods: This was a qualitative research project with a phenomenological approach. The research population was the employees of Melli Bank branches in the 10th district of Mashhad City, Iran in 2021, from among whom a sample of 10 people was selected by purposeful sampling, the sampling process continuing until saturation. Data were collected through semi-structured interviews and analyzed using the inductive thematic analysis method.
Results: Data analysis showed 12 sub-themes, 3 main themes including challenges at the individual, interpersonal and organizational levels, and a core theme.
Conclusion: The findings of this study show that the Bank employees’ concept of the Corona pandemic can affect their work efficiency.  These findings can be used for planning to solve the problems and challenges of this group of people after the Corona pandemic.
