Abstract
Musculoskeletal disorders, early fatigue induced by static work and the same symptoms are caused by inappropriate designed tools, equipment, building and workplace. Inadequate educational furniture is taken to be the reason of severe posture problems such as low back pain, spinal disorders, fatigue, shoulder and neck pain, and disturbance circulation in legs. So ergonomic design of educational furniture should be carefully considered. Materials and Methods: The present research was a cross-sectional study. Samples included desks and chairs (n=150) chosen from reading rooms of dormitories and faculties of Isfahan university of medical sciences Isfahan- Iran. In the study 2 parameters from desk and 5 parameters from chairs were assessed using a tape-measure and a set-sqare. Data were analyzed by SPSS ver 10 software. Results: Comparing the results from the mean of measured values (for seating height, desk height and desk clearance) indicated a significant difference between them (p<0. 00). Conclusion: Findings of the study showed that existing standard in Iran about chairs and tables for educational institutions should be reviewed. Also the most important problem with chairs and desks are seating height and desk surface height respectively. These two parameters didn’t match with anthropometric dimensions of the sudents of Isfahan university of medical sciences.

Abstract
Background: The present study investigated the prevalence of intestinal parasites in individuals who referred to hospitals affiliated with Zahedan University of Medical Sciences, Zahedan, from 2019 to 2023.
Materials and Methods: The present descriptive study was conducted cross-sectionally and consisted of 5,976 individuals referring to the hospitals with gastrointestinal. To describe the data, mean (standard deviation) and number (percentage) were used according to the studied groups.
Results: The results of the study showed that 1,510 people were diagnosed positive. The highest rate of infection by intestinal protozoa was related to Giardia, affecting 528 people (8.8%), while the lowest rate of infection was related to Endolimax nana, affecting 10 people (0.16%). The highest prevalence rate of infections by intestinal worms was related to Entrobius vermicularis, with 64 people (1.07%), whereas the lowest prevalence rate was associated with Trichuris trichiura, with 19 cases (0.31%).
Conclusion: The comparison of the percentage of pollution in the current study with other relevant studies in the past years showed that the prevalence of intestinal parasitic diseases in this region has decreased significantly, similar to other regions of the country. At the same time, the rate of infection by intestinal protozoa is significantly higher than by intestinal worms. This issue can be due to their direct and easier transmission compared to the worm eggs or larvae.
