Abstract
Introduction: Many calls already perform by cell phones that have need to radiation exposure by users. Because of health reasons and some doubts about effects, this study was conducted to determine the extent of the mobile phones radiations and self report symptoms of users.
Material and Method: In this cross-sectional study, 80 available randomly users contain students and staffs of Hamadan University of medical sciences in 2012 were selected. Electro Smog meter TES-593 was used as radiation measurements tool. In order to assess health effects of mobile phones’ radiation, a self-administered survey questionnaire were used. Statistical analyses were performed using T-test, ANOVA and X2 tests by SPSS 11.5.
Results: Results showed that the conversation mode had a highest level of electromagnetic indices in the studied cell phones. Compare means of power density that emitted from studied mobile phones had significantly difference (P=0.001). Relationship between exposure to the mobile phones radiation by symptoms of head-ache, anxiety and sleep disturb were significant (P=0.02, P=0.03, and P=0.002 respectively).
Conclusion: Although, there is founding the relations between exposure to cell phones electromagnetic fields and some self-reported symptoms in line with same reports, These symptoms can not be absolutely attributed to the use of mobile phones. With these considerations it is recommended that for prevention of health risks from cell phones, safe type selection, control of call duration and frequency of use of these devices should be mentioned.

Abstract
Objectives: Scientometrics is a research field that examines and analyzes scientific trends and patterns in various scientific journals. This study aims to analyze the content of articles published in the Journal of Applied Ergonomics in the last ten years and determine the distribution pattern of the articles according to the themes extracted.
Methods: Using the method of directed content analysis, the number of 2,148 articles published in the last 10 years were extracted from the "Journal of Applied Ergonomics" website and categorized according to the topic, the nationality of the authors, and the year of publication. For the topic categories of articles, the existing categories of published articles and the topic tree schema of the article submission website of selected international journals were used. EXCEL 2021 software was used for data preparation and analysis.
Results: Among the twenty-two extracted topics, three main topics, including "Physio-psychological Status and Occupational Factors," "Human-machine interaction, Human-computer interaction", and "Ergonomic product and service design" elucidated approximately 50% of the variance in published articles in this reputable journal under study. Among these, there was a particular emphasis on the topic of "Physio-psychological status and occupational factors." The subjects of "Physio-psychological status and occupational factors," "Human-machine interaction," and "Human-computer interaction" have had an upward trend in recent years. Moreover, authors from the United States of America, with 25.84% frequency, have contributed the most to the publication of articles in this Journal.
Conclusion: The thematic framework and distribution patterns extracted in this study can contribute to the educational and research planning in the field of professional health for universities, research centers, and relevant organizations. These findings can guide strategic decisions and support targeted efforts to advance ergonomic practices and the dissemination of knowledge within the field.
