 Soccer is one of the most popular sports and it is necessary to use preventive exercises in this sport. Therefore, the aim of this study was to investigate the effect of the exercise programs obtained from the functional movement screening tests on hip muscle strength and dynamic postural stability to prevent anterior cruciate ligament injury in healthy male soccer players.

 The statistical population of the present study consisted of healthy male football players aged 18-27 years and with a history of playing in provincial league teams who were eligible to enter the study. Thirty football players (age: 22 ± 2.98, height: 185.93 ± 6.5, and weight: 83.06 ± 6.27) were selected as a sample and randomly divided into two equal experimental and control groups. Kincam isokinetic dynamometer and Biodex balance device were used to evaluate the strength of hip muscles and dynamic postural stability, respectively. An exercise program as the warm-up was performed for 20-25 minutes per session, three sessions per week, and for eight weeks, by the experimental group. The Control group continued to perform their daily program. It should be noted that informed consent and voluntary consent were obtained from all subjects. Correlated t-tests and analysis of variance with repeated measures were used for statistical analysis at the significant level of P≤0.05.  

 Significant differences were observed in the strength of the hip extensors, external rotators, and abductors muscles in both legs (P<0.05) as well as total deviation index, anterior-posterior deviation index, and a medial-lateral deviation index (P <0.05) between experimental and control groups.

 It could be concluded that training programs obtained from functional movement screening tests effects hip muscle strength and dynamic posture stability in healthy male soccer players. Therefore, it may prevent Anterior Cruciate Ligament injuries.

With the prevalence of Covid-19 and the involvement of many countries, nurses as a large segment of the medical staff on the front lines of the disease, have the most contact with patients and rich resources of experience, while caring for patients from attendance hours. The hospital is until his discharge or death. Accordingly, the purpose of this study was to investigate the experiences of nursing managers at the time of the onset of the Covid-19 epidemic in one of the leading hospitals in the reception and treatment of Covid-19 patients. Methods and Materials: This was a qualitative study with a conventional content analysis method. The study population in this study consisted of nursing managers including head nurses and supervisors who were active in the Covid ward in relation to Covid-19 patients.

Data were collected and analyzed from 15 participants, including 12 females and 3 males. The results showed that the challenges that nursing managers, including head nurses and supervisors, presented as the experiences of Covid-19 time include the three main categories of physical and mental issues, health literacy, and barriers to patient service.

By properly implementing health measures through access to adequate resources including medical and pharmaceutical equipment, efficient manpower, and financial interactions, the challenges raised in the experiences of nursing managers can be overcome.

Work-related musculoskeletal disorders are the most important occupational diseases. This study aimed to investigate the correlation between company ergonomic situation and anthropometric dimensions with musculoskeletal disorders in workers.

82 female and male volunteer workers participated in this cross-sectional study. The musculoskeletal disorders, ergonomic situation, and anthropometric dimensions were examined using the Nordic and Dutch musculoskeletal questionnaires and tape meters. The study protocol was approved by the Committee for Ethics in Biomedical Research of the Allameh Tabataba’i University with obtaining ethics. Data were analyzed using SPSS ver.26 software and running Spearman and Chi-Square tests at the significance level of 0.05.

Significant correlations were found between the company ergonomic situation with musculoskeletal disorders in the neck (P=0.001), shoulder (P<0.001), elbow (P=0.004), wrist (P=0.004), upper back (P<0.001), lumbar (P<0.001), thigh and buttock (P=0.028), knee (P<0.001), and ankle (P=0.036). Moreover, there were significant correlations between the ratio of chair height to popliteal height with musculoskeletal disorders in lumbar (P=0.026), thigh and buttock (P=0.015), knee (P<0.001), and ankle (P=0.038), also between the ratio of chair depth to thigh length with shoulder (P=0.043), upper back (P<0.001), lumbar (P<0.001), thigh and buttock (P=0.001), and knee (P=0.004), and between the ratio of chair height to shoulder height with shoulder region (P=0.002).

It seems that there is a correlation between company ergonomic situation and the proportion of anthropometric dimensions with chair dimensions with the prevalence of musculoskeletal disorders in workers.

 Although there are no exact statistics on the number of motorcycles in Iran, apparently due to the danger and increasing use of motorcycles, the incidence of motorcycle-related traffic accidents in Iran is rapidly increasing. Therefore, the present study aims to determine the epidemiological status of accidents leading to death in motorcyclists in Dezful, Iran.

 The present study was a descriptive-analytical and cross-sectional study that was conducted in 2021. The statistical population included the deaths due to motorcycle traffic accidents, whose burial certificates were issued by the office of legal medicine in Dezful. The samples were selected as a census from legal medicine statistics during the years 2015-2018. The data were confidentially entered into a researcher-made checklist without mentioning the name of the deceased and then analyzed using SPSS 24.

The highest number of victims was under 30 years old and the lowest number was 40-50. The cause of death was due to head injuries (63.8 percent), multiple trauma (26.2 percent), bleeding (5.7 percent), and other reasons (4.3 percent). Most of the deaths were related to men and due to traffic accidents that occurred in September, October, and November months. Also, 50.4 percent of the accidents occurred in the city and 49.6 percent on suburban roads.

 Most of the traffic accidents among motorcyclists are related to the youth age group. Therefore, it is imperative to pay attention to this group in order to reduce casualties. Therefore, appropriate traffic culture should be promoted and measures should be taken to reduce the occurrence of accidents by strictly enacting and enforcing the laws.

The Arbaeen ceremony has increased the volume of road traffic in Kermanshah province, so accident analysis can improve policy-making and traffic accident prevention programs. The purpose of this study was to analyze traffic accidents on suburban roads of Kermanshah province using GIS in Arbaeen trips.

This applied study was performed descriptively-analytically in 2019 in the ArcGIS 10.6 software environment. The study was conducted in three phases: data collection, database preparation, and data analysis. In the first phase, the vector layers of the study were created and the accident data of 2018 were collected from Police Office, then the accident data related to the Arbaeen days (13.10.2018- 2.11.2018) were extracted from this collection. In the second phase, the study environment map was entered into ArcGIS 10.6 and their vector layers and descriptive tables were created. Phase 3, data analysis was performed to identify the cause, type, and condition of accidents, accident hotspots, and distribution.

In the Arbaeen days of 2018, 149 accidents occurred, as a result of which there were 20 deaths and 129 injuries. Personal vehicle crashes with 110, multi-vehicle collisions with 65, and speeding with 54 were the most common types of vehicles, modes, and causes of accidents.

High vehicle traffic in the Arbaeen days requires careful planning. Therefore, improving the infrastructure will improve the traffic situation and reduce traffic accidents. Proper distribution of resources and facilities, relief, and rapid response in Arbaeen traffic routes are also essential.

Numerous theories and frameworks have been used to understand and intervene in behavioral determinants, but these variables have not been validated in the safety behavior of individuals in all industrial societies and diverse industries with different cultural characteristics. The purpose of this study is to identify and prioritize the factors affecting the improvement of safety behaviors of the executive staff of Tehran Municipality.

The statistical population of this study is HSE experts of Tehran Municipality. The data collection tool in this study is the use of library studies and the Delphi technique to identify individual and organizational factors affecting the correction of employee behaviors. Data analysis was performed using AHP hierarchical analysis and EXPERT CHOICE software.

According to the results of the identification of the organizational factors, it can be stated that among the organizational factors affecting the improvement of safety behaviors of municipal executive staff, safety culture with a relative weight of 0.109 is recognized as the most important organizational factor. In general, it can be said that between individual and organizational components; Individual components had a higher rank than organizational components. On the other hand, the findings of ranking individual factors also expressed that the risk perception component with an average rank of 0.179 has the highest rank.

 For earlier conclusions in advancing the system and correcting the behavior of Tehran Municipality employees in the fields of safety, it is suggested that goal setting and planning be prioritized on 1- risk perception 2- attitude 3- awareness and knowledge 4- culture) Safety 5- Management commitment 6- Organizational safety atmosphere 7- Effective communication.

National Disaster Response Framework has been developed in order to properly direct the operation process and response to various types of disasters in the health system in order to use this framework to unify the guidelines related to disaster risk management and according to the current structures. , Related laws and regulations are implemented. The aim of this study was to investigate the effectiveness of the implementation of the national program of the health system response to disasters and emergencies based on the views of healthcare providers working at North Khorasan University of Medical Sciences in 2021.

This descriptive-analytical study was conducted in 1400. The target population was healthcare providers. The data collection tool was a researcher-made questionnaire with two areas of preparation and response, which was designed and developed according to the areas of the National Health System Response Program. SPSS software version 22 was used for data analysis and logistic regression was used to analyze the data to examine the relationship between variables. In this study, the principles of the Helsinki Declaration were considered.

The number of participants in this study was 453, of which 146 (32.2%) were male and the rest were female. 65.6% of the participants in this study considered the effectiveness of the national health system response program in disasters and emergencies as favorable. The effectiveness of effectiveness in the field of preparedness was equal to 66.7% and in the field of response 55.6%. According to the results of multivariate logistic regression tests, there is a significant relationship between the experience in disaster situations, responsibilities in disasters, city of providing care, place of employment with effectiveness score status, and sub-areas of preparedness and response.

It seems that the national response plan is far from achieving the desired results in terms of the areas under study, and measures such as staff training, in-service orientation courses, and training should be provided to increase staff preparedness to deal with the crisis.

 Noise is the industry's most common occupational harmful factor. Therefore, the present study aimed to identify and prioritize occupational groups exposed to noise in an oil field.

 This cross-sectional study was started in the winter of 2021 by examining the job description of employees and performing dosimetry using the CEL-360 device. The sound pressure level distribution was measured using the Casella CEL device and based on ISO 9612-2009 (E). Using Surfer 21 and AutoCAD 2020 software, an isotonic map was prepared, and priority occupational groups and primary noise sources were identified using Noise Control Priority Index (NCPI). In stations with more than 85 dB sound pressure levels, noise frequency analysis was performed, and in the last stage, appropriate corrective action was presented according to the production process.

 The findings of this study showed that 16% of the area has the priority for control measures in the danger area, and 23.56% is located in the precautionary area. Operations were identified among the occupational groups with the highest NCPI score (1.5) to be prioritized in the hearing protection program.

 The present study results show that the combined sound pressure level, duration, and the number of exposed people can provide a suitable model for prioritizing voice control and identifying occupational groups in need of care in the hearing protection program.
