Objective: Hospitals are the first place to refer the victims of emergencies and disasters. Hamadan province, as one of the provinces in western Iran, like other parts of this country is exposed to various emergencies and disasters. This study was conducted to evaluate the level of hospital disaster preparedness in the Hamadan province of Iran using a standard tool.Methods: This study was conducted in Hamadan province’s hospitals in Iran. The Persian version of the World Health Organization Hospital Emergency Response Checklist was used as an evaluation tool. It consists of nine key components: command and control, triage, human resources, communications, surge capacity, logistics/supply management, safety and security, continuity of essential services, and post-disaster recovery. Data entry and analysis were performed using IBM® SPSS® software (version 18).Results: Fifteen hospitals participated in this study (response rate 83 percent). Most hospitals (53.33 percent) were in moderate preparedness level, 26.66 percent are in good, and 13.33 percent are at a poor level. There was no significant relationship between “the hospital type” and “the hospital size” (number of beds) and preparedness score (p 0.05).Conclusions: This study showed that most of the hospitals in the Hamadan province regarding the components of “logistics” and “essential services” are at a poor disaster preparedness level. Accordingly, the hospital authorities and managers must adopt a comprehensive strategy for strengthening the hospital disaster preparedness measures, especially in these components.

: Studies have documented criteria for the prevention, diagnosis, and treatment of COVID-19 pneumonia as more information has become available about its symptoms and complications. Similar to other coronavirus-induced cases of pneumonia, COVID-19 pneumonia causes acute respiratory problems. The chest CT scan, which is easily available in almost all areas, is a common imaging technique for diagnosing pneumonia. Its findings, which are accompanied by high speed, quality, and accuracy, allow the radiologist to easily identify affected areas of the lungs and to determine typical radiological features of patients with pneumonia caused by COVID-19. These features include ground-glass opacity, multifocal patchy consolidation, and interstitial changes with the peripheral distribution. The highest incidence occurs in the 4th and 5th lobes, where about 50% to 75% of the lesions observed. For infected patients, the CT scan protocol includes administration of HRCT technique in the inspiration phase with spiral 4-slice devices and higher. Scan parameters also include KV: 100 - 120, and mAs: 20 - 30, thickness = 1 - 2 mm, spiral, single breath-hold, and Pitch = 0.8 - 1.5, which are determined for all patients. Since there are restrictions on using ionizing radiation for pregnant women, it is recommended to initially conduct PCR tests. If necessary, typical radiography with an abdominal shield can be used for women in the first trimester of pregnancy, and the HRCT technique in low doses can be used for those in the second and third trimesters.

Introduction: With the alternation of the educational system from a three-stage into a two-stage system in Iranian schools since several years ago, five-year-old children entered from kindergartens to primary schools. This study was conducted to investigate the harmonization of classroom furniture with anthropometric dimensions in preschool students.  Methods: In this cross-sectional study, 366 male and female preschool students were selected by cluster sampling method in Kerman, Iran.  Some of the anthropometric dimensions such as shoulder, elbow, and popliteal height, popliteal buttock length, and buttock breadth were measured. mean, maximum, minimum, standard division, and 5th, 50th, and 95th percentiles were calculated for both the sexes and were compared with five dimensions of the existing seats. Next, the dimensions of the standard seats were determined according to the anthropometric dimension’s students. Data were analyzed using SPSS 21 . Results: Independent-Samples T-test between girl and boy pre- school students in Kerman city showed just popliteal height had a siginificnt diference (p ≤0.05). Match of antropometric musurmants with seat dimentions indicated that there is no consistency between the seats and anthropometric dimensions in. Armrest height, seat height, backrest height, seat depth and seat breadth were matched with (0, 0.5, 10, 6.7, 0) and (0.7, 28.7, 6, 2.5, 0) percent of anthropometric musurments of girl and boy students respectively Conclusions: Due to adding a new grade to primary school, it seems that no work has been done for improving the furniture. Therefore, in this article, we presented the dimensions of an appropriate seat. This may help not only save production costs in the industry but also increase the matching between students' anthropometric and seat dimensions.
