Abstract
Recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. Life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after disasters are helpful. This article considers the related texts with the aim of reviewing the indicators of recovery after disasters. The examined issues are basics of recovery, recovery in the form of process, as well as components and dimensions of recovery.

Abstract
Background: To reduce traffic injuries in the country, health professionals should have accurate estimates of road traffic deaths. Multiple and sometimes inconsistent statistics presented by organizations in charge create high degree of uncertainty for planners and decision makers. To achieve an accurate estimate, several methods are available. Of them, capture-recapture
method seems to be an appropriate and affordable method regarding the reliability of the data sources. This study aimed to estimate the number of road traffic deaths in Kurdistan Province during 2004-2009, using capture-recapture method and based on 2 sources of data obtained from Death Registration System and Forensic Medicine Department.
Materials and Methods: All deaths due to road traffic accidents in Kurdistan Province were extracted during 2004-2009. These deaths were legally registered in Death Registration System and Forensic Medicine Department. Shared cases among these 2 sources were identified based on full name, age, gender, and date of death and finally the accurate number of deaths was
calculated using the correct volume formula.
Results: During study period, Forensic Medicine Department of the province had registered about 3289 cases of road traffic mortalities and Death Registration System had registered 3771 cases of death resulting from road traffic accidents. Using capture-recapture method, the number of deaths in the same years was estimated as 5726 people (5818-5634:CI95%). The
proportion of mortality registered in the Death Registration System and Forensic Medicine Department of the province to the total estimated deaths were 65.8% and 57.4%, respectively and both systems together covered 85.4% of road traffic deaths, i.e. under-reporting of about 832 people.
Conclusion: The results of the present study indicate that none of 2 sources of Forensic Medicine Department and Death Registration System, per se or both, fully covered road traffic mortalities and using capture-recapture method can help estimate the actual number of deaths.

Abstract
Background: Traffic accidents are the main cause of death and disability in the world and Iran. The Injuries caused by traffic accidents may result in severe limitations and worst outcomes in various aspects of lives of traffic accident injured people and their families. Therefore, understanding their experiences is very important to design better programs with regard to their treatment and returning to the society. In this regard, we conducted this study with the aim of understanding and describing the experiences of encountering with physical trauma resulting from traffic accidents.
Materials and Methods: This study was conducted with qualitative research approach, using qualitative content analysis method. The study participants had a record of upper and or lower extremity injuries caused by traffic accidents of at least 3 months and at most 2 years after the accident. They were chosen by purposeful sampling method. Data were collected through semi-structured interviews and continued until data saturation. Data analysis was carried out using content analysis method.
Results: The study findings based on the experiences of participants were conceptualized in three main categories; experiencing some limitations, disturbances in performing professional duties, and family problems caused by trauma. Conclusion: The study findings showed that injured people due to traffic accidents experience numerous constraints in different areas of their lives. Accordingly, proper interventions can be designed based on understanding these needs and experiences from participants’ own words to alleviate these problems. Finally, the study results provide a new insight to the medical team to understand these patients and their real health problems in a more realistic way.

Abstract
Background: Although natural disasters leave thousands of deaths and wounded, one of their most significant outcomes is empowering women as well as taking measures with special attention to women. This study aimed to analyze women’s cooperation and its affective factors in natural disasters and accidents.
Materials and Methods: The study design is cross-sectional and descriptive. The study population comprised the women living in Bam, Iran and the sample size was calculated as 385. The study instrument is a researcher-made questionnaire. To analyze the data, the descriptive statistical methods, the statistical correlation test, and 1-way analysis of variance were performed by using SPSS 16.
Results: The study result about the effects of the women demographic characteristics on their cooperation showed that there were no relationships between women’s cooperation and their marital status or degree of education. However, there were significant and positive relationships between their cooperation and variables of age, being indigenous, and occupational status.
The results have also indicated that there were significant relationships between women’s cooperation and variables of knowledge and attitude.
Conclusion: Women, despite their vulnerability in natural accidents, have the capability in performing different tasks such as taking care and accommodating the injured family members, and making peace and relief in difficult and undesirable situations after natural disasters such as earthquake. However, the results of this study revealed that women’s cooperation in different parts of crisis management was very limited. This matter demands more attention of the responsible authorities.

Abstract
Background: Many organizations, especially at the time of accidents, disasters, and critical conditions, cannot provide their services without the presence of volunteers. When accidents and disasters occur, the first persons who normally appear at the scene are citizens. Volunteer citizens with the skills and local knowledge can play important roles when accidents and disasters occur and can provide valuable assistance to the relief forces. The current article aimed at examining the role of volunteer citizens in response to accidents and disasters.
Materials and Methods: The current study examined the published articles from 2000 to 2016 based on the following keywords: informal volunteers in the disasters, challenges facing volunteer citizens in accidents and disasters, informal volunteers and disasters in local and foreign electronic databases including SID, Magiran, Iran Medex, ISC, Google Scholar, PubMed, ISI, and Scopus.
Results: Based on the search strategy, 50 articles were examined and the keywords, definitions, volunteer roles, role of volunteers in accidents and disasters, various types of informal voluntary activities, and volunteer citizens’ participation were examined.
Conclusion: Studies referred to the roles, definitions, and challenges that informal volunteers face in various stages of accidents and disasters and the obvious point in the research was that more adaptive and comprehensive crisis and emergency management models are needed to utilize the capacities and flexibility of volunteers available within and between communities in disasters, and the network structure management can be helpful to manage the volunteers.

Abstract
Background: Collaboration of patients in caring is regarded as a gold standard in professional care associated with modern nursing. Considering the complexity of the concept, it is imperative to analyze caring of patients with motor disability caused by traffic accidents.
Materials and Methods: This is a qualitative study to analyze the concept of collaboration in caring for traffic casualties using a hybrid model in three stages. In the first stage, to conduct a systemic review, a literature search was performed using databases such as Blackwell, CINAHL, MEDLINE, and Elsevier with the keywords: Collaboration in caring and orthopedic victims of traffic accidents. The literature search resulted in 110 related reviews up to 2016. In the second stage or field stage, for the importance of collaboration in caring for traffic casualties, 7 traffic victims and 3 nurses were interviewed and data were analyzed by content analysis. Finally, in the third stage, an overall analysis was performed according to the findings in previous stages.
Results: Combining the results of reviews and findings of field study, we obtained 87 codes, 14 subcategories, and 5 categories (“organizational factors in sharing information and knowledge”, “promoting a sense of responsibility in patient”, “patient empowerment for health promotion”, “mutual trust”, and “hypersensitivity to active engagement to return to normal life”) in content analysis.
Conclusion: Recognizing the concept of collaboration of patient with motor disability in caring from the orthopedic viewpoint, managers and nurses will be able to plan and execute management and educational activities according to the insight obtained from scientific findings to provide suitable conditions in this regard.

Abstract
Background: Human factors have the most significant effects on the occurrence of traffic accidents among the three factors of human, road, and vehicle. The driver is a significant traffic safety concern. Interventions that enhance driver’s safety are required. Risky behaviors of drivers on the road influence physical healthy and personality. The aim of this study is to report the protocol for a sequential explanatory mixed methods study that set out to determine the drivers’ traffic factors, the associated factors and exploring the perception of drivers about the risky traffic factors on the road. The ultimate purpose of the study is to design a preventive and cultural based strategy to promote driver’s safety.
Materials and Methods: This is a sequential explanatory mixed methods design. The study has two sequential strands. The follow-up explanation model has used to develop the quantitative results by gathering qualitative data from participants who could assist in elucidating the results correctly. During the first strand (a quantitative phase) and a population-based cross-sectional survey of a sample of drivers of all ages and level of experiences will be carried out using the proportional random sampling method, in Tehran, Iran. Data will be collected by questionnaires involving items on socio-demographic information, items on measuring health (Drivers Medical Questionnaire), and questions on five-factor Personality (NEO-FFI), drivers risky behaviors (Manchester driving behavior questionnaire). Questionnaires will be completed through a face-to-face interview. In the second strand, a qualitative study will be conducted. A purposeful sampling strategy will be used, and participants who can help to explain the quantitative findings will be selected. Individual fully developed interviews will predominate data collection in the qualitative strand the. A qualitative content analysis approach will be undertaken to create an itemized understanding of the traffic-risky behaviors among drivers of all ages and level of experiences.
Conclusion: The findings of this explanatory mixed methods study will provide information on traffic-risky behaviors by all drivers. The results will be implemented to design a cultural based strategy, and intervention programs are to be designed to promote driver’s health in the community.

Abstract
Background: Driving fines are one of the tools to reduce driving violations, and consequently, injuries due to car accidents. In 2010, a new set of laws and fines were passed with the aim of deterring driving violations. Since the second half of March 2013, the new laws and fines were enforced throughout the country. To compare the number of accident victims referred to the hospitals affiliated to Mashhad University of Medical Sciences before and after the implementation of the new traffic offenses law.
Materials and Methods: This was a descriptive-analytic study. The study population consisted of all accident victims referred to the emergency department of hospitals of Mashhad University of Medical Sciences from March 2014 to September 2017. Sampling method was total enumerative method. For data collection, a checklist was used. After obtaining the necessary permissions, the researcher completed the checklist by referring to the hospitals and the Deputy of Treatment of Mashhad University of Medical Sciences. The relevant data were extracted from the Hospital Information and MedCare Systems. In addition to comparing the average number of victims before and after the implementation of the new law, the average number of victims were compared in terms of the body part injury, the site of the accident before and after the implementation of the law. The obtained data were analyzed by using descriptive and analytical statistics including t test.
Results: The average monthly number of casualties before the implementation of the new law was 3053 and after the implementation it increased to 3492 people. This difference was statistically significant (P≤0.05). Although this increase was observed in the average number of the victims in all four body parts groups, after the implementation of the law, only the difference between the average number of victims with multiple body injuries was statistically significant (P≤0.05). In addition, the average number of the accident location in all four groups of the accident locations increased after the implementation of the law. However, only the difference between the average number of the accidents occurred on suburban roads before and after the implementation was statistically significant (P≤0.05).
Conclusion: On the whole, increasing driving fines does not seem to have a significant impact on reducing road traffic injuries. A more detailed investigation of this challenge is recommended to identify possible causes of the ineffectiveness of fines.

Abstract
Background: Due to the importance of industrial accidents in workplaces, the current study aimed at epidemiologically investigating occupational accidents in some industrial sites in Semnan, Iran.
Materials and Methods: The current descriptive-analytical study was conducted on all accidents taking place from 2014 to 2016 in some industrial sites in Semnan. The data were extracted from the Department of Labor and Social Affairs of Semnan. SPSS software version 21 was employed to analyze data using Chi-square and logistic regression tests.
Results: The mean and standard deviation of workers age in non-fatal and fatal accidents were 30.58±16.14 and 35.17±12.34 years, respectively. There was no significant difference in variables such as gender, workers experience, marital status, type of industry (construction, mining, rubber, and agriculture), and educational level between fatal and non-fatal accidents (P>0.05). A significant relationship was observed between insurance coverage status and fatal accidents (P=0.001). The rate of fatal accidents was about five times more in 2015 than 2014 (P=0.01; OR=4.76).
Conclusion: The rate of accidents in industrial sites can be significantly reduced by taking advantage of accident prevention programs and training courses. Occupational safety and health program can promote the performance of workers. In this regard, the development and conduction of industrial emergency plans can reduce fatal accident rates.

Abstract
Background: Road traffic accidents in Iran are a critical issue that hinders economic development and one of the main threats to the health and safety of people in the community. The statistics indicate that after cardiovascular diseases, traffic accidents are the second leading cause of death in different age groups, which reflects the necessity of prediction in this area.
Materials and Methods: The present study investigated the data of the traffic-accident injured people between April 2009 and March 2012 in Golestan, Mazandaran, Guilan, and Ardebil provinces, presented to forensic medicine. We used the Box-Jenkins method as one of the most advanced methods in prediction and future studies in the field of health systems, to estimate the number of injuries by province, for the years 2016 to 2019.
Results: The obtained results suggested the appropriate time series patterns for predicting injured people in Golestan Province with autoregressive integrated moving average (ARIMA) (4, 2, 4), Mazandaran Province with ARIMA (3, 1, 5), Guilan Province with ARIMA (3, 1, 4), and Ardabil Province with ARIMA (5, 1, 2). Furthermore, the mean percentages of absolute error for different provinces were as follows: Golestan Province, 0.114; Mazandaran Province, 0.064; Guilan Province, 0.078; and Ardabil Province, 0.1250. These data demonstrate the high precision of the Box-Jenkins method in predicting the number of traffic-accident injured people, especially in Mazandaran and Guilan provinces. Estimated values for 2016 to 2019 indicate that the road traffic injuries are increasing in Golestan Province and decreasing in Mazandaran, Guilan, and Ardebil provinces.
Conclusion: The high precision of the Box–Jenkins method makes it an appropriate way for experts and authorities to predict traffic accident injuries in Golestan, Guilan, Mazandaran, and Ardebil provinces. The reduced number of casualties in Mazandaran, Guilan, and Ardebil indicate a progressive improvement in the transportation system conduct in these provinces. Moreover, Golestan Province is moving towards an increase in traffic accidents, requiring re-planning to reduce accidents there.

Abstract
Background: The most crucial issue in the disaster and accidents is the health management of the affected community because accidents and disasters always have a significant impact on hygiene, general health, and the wellbeing of the stricken community. Considering the hospitals’ function and their front line position in managing the victims of accidents and having to continue and even increase their activity at the time of accidents and disasters, they should have a program of coping with accidents. In this regard, the current study investigated the preparedness of hospitals in Ardabil Province, Iran, in response to unexpected events.
Materials and Methods: This was a descriptive, analytical, and cross-sectional study conducted in 15 hospitals in Ardabil Province in 2017. To collect study data, a two-part questionnaire was used. Its first part investigated the demographic data of the hospitals. The second part was the national tool to assess hospital preparedness in accidents and disasters with 91 questions in 9 areas of preparedness (command and control, communication, safety and security, triage, capacity increasing, continuity of essential services, workforce, resource management, and post-disaster recovery). The collected data were analyzed using descriptive statistics.
Results: The findings of this study revealed that out of the 15 studied hospitals, only 4 were well prepared, 3 were poorly prepared, and 8 hospitals were moderately prepared for crisis management. On average, out of the 9 investigated aspects, triage, human resource management, and recovery after disasters had the lowest status.
Conclusion: Considering the obtained results and the importance of preparing for unexpected events, it can be useful to plan and have an explicit instruction, and then implement and evaluate it to increase the preparedness to confront unexpected accidents in all hospitals.

Abstract
Background: Drivers play a crucial role in accidents. By paying attention to brake lights, a driver may find out about danger and react adequately. Rear-end collision accidents are caused by the driver’s inattention or slow reaction. This study aimed to determine the effect of dynamic flashing brake lights (7 Hz) on drivers’ brake reaction time using the driving simulator.
Materials and Methods: This experimental study was done on 46 volunteer drivers (10 females and 36 males). After verification of drivers’ vision health by an optometrist (10/10 complete and non-color blindness) and responding to a demographic questionnaire, the participants were subjected to drive for an hour during day and night using a driving simulator system with the standard and dynamic flashing brake lights.
Results: The results indicated that for each 1 year increase in the drivers’ age, the brake reaction time decreased 11.585 ms. Women had slower brake reaction time than men (75.52 ms). No significant relationship was found between the driving condition and brake reaction time. Computer driving gamers had shorter mean reaction time compared with non-game players. The time elapsed since taking a driving license had no significant effect on reaction time. Using flashing brake lights reduced the brake reaction time of drivers (323.42 ms; P<0.001).
Conclusion: The current research using dynamic flashing brake lights with a flashing frequency of 7 Hz showed that flashing brake lights significantly reduced the brake reaction time. This reduction was equivalent to 10.78 m at a speed of about 120 km/h or 7.19 m at 80 km/h.

Abstract
Background: One of the indicators for measuring the development of a country is its death rate caused by accidents and disasters. Every year, many people in Iran are drowned for various reasons. This study aimed to predict the trend of drowning mortality in Iran using statistical models.
Materials and Methods: This research was a longitudinal study using time-series data of drowning deaths obtained from the Iranian Legal Medicine Organization during 2005-2017. The Autoregressive Integrated Moving Average (ARIMA) model was used for forecasting, which is based on the Box-Jenkins method consisting of the Autoregressive (AR) model, Moving Average (MA) model, and Autoregressive Moving Average (ARMA) model. The obtained data were analyzed in ITSM software.
Results: A total of 14127 people have died due to drowning in Iran, during 2005-2017, with an average death toll of 1086 people per year. In 2017, the highest number of deaths caused by drowning was recorded in Khuzestan Province (n=161) and the lowest number in South Khorasan Province (n=1). Estimates of the drowning trend indicated that the number of drowning deaths in Iran would continue to decline in the coming years.
Conclusion: The high accuracy of prediction using the Box-Jenkins method indicates its effectiveness for experts and managers to predict drowning death rates.

Abstract
Background: Nowadays, safety management plans have an effective role in reducing the incidence of accidents. Therefore, this study aimed at investigating the role of safety management systems on accidents and the status of safety performance indicators in a combined cycle power plant in 2011.
Materials and Methods: This descriptive-analytical research was carried out in two stages in all Yazd Combined Cycle Power Plant units on accident victims from 2004-2011, based on the documentation of the previous years and using census sampling. The Accident Frequency Rate (AFR), Accident Severity Rate (ASR), and Frequency Severity Rate (FSI) indices were derived from the OSHA standard using the formulas and data obtained from the completed questionnaires and interviews with the people.
Results: The total number of accidents was 287 cases through the studied period (8 years). The results showed a significant relationship between age and work experience, as well as between age and marital status. The main causes of accidents were unsafe acts. The lowest level of personal protective equipment was used in 2004 (15.2%), whereas the highest rate was used in 2011 (30%). After the implementation of the Integrated Management Systems (IMSs), accident indicators showed a decreasing trend regarding the washing time. Also, the amount of AFR, ASR and FSI indices of the accidents in terms of work shift indicated a significant decrease in 2004 than after the implementation of the safety management systems.
Conclusion: According to the results, due to the positive impact of safety programs (IMS), incident indicators had a downward trend and unsafe acts were decreased.

Abstract
Background: Road traffic accidents are currently among the most essential public health issues. According to the World Health Organization, given the rapid growth of road transport globally, road traffic accidents could be the third leading cause of death and disability in the world by 2020. This article examined the role of the human factor in road accidents during the Nowruz holidays, as a major cultural event in Iran.
Materials and Methods: We explored the data of road accidents that occurred in Nowruz in 2016 and 2017 in Iran. Traffic accident data concerning the Nowruz holidays of 2016 and 2017 were collected by census method of sampling and based on the report of highway police. Additionally, the frequency of these accidents was analyzed according to travel time, accident type, gender, age, education, and vehicle type in different provinces.
Results: The present study findings suggested that among human factors affecting Nowruz accidents in 2016 and 2017, the highest frequency belonged to unnecessary speeding. As in 2016 and 2017, it was the main responsible characteristic for 56.42% and 55.01% of accidents, respectively. In Nowruz 2016, the provinces of Tehran, Khorasan Razavi, Isfahan, Fars, and Khuzestan; in Nowruz 2017, the provinces of Tehran, Isfahan, Khorasan Razavi, Fars, and Gilan encountered the highest rates of accidents leading to injuries and deaths.
Conclusion: To control unnecessary speeding and regulations disregard, planning for culturizing and the community-level education are suggested. Besides, increasing the quality and intelligence of vehicles and the construction of sliders, vertical lines on the road, warning signs, and billboards could help reduce the rate of accidents. Creating a working group of experts in psychology, traffic, etc., to study the pathology of dangerous behaviors, useless haste, and disregard for regulations and providing solutions could also be effective.
