This study used methodologies of descriptive and quantitative statistics to identify the contributing factors most affecting occupational accident outcomes among electrical contracting enterprises, given an accident occurred. Accident reports were collected from the Occupational Safety and Health Administration's fatality and catastrophe database. To ensure the reliability of the data, the team manually codified more than 600 incidents through a comprehensive content analysis using injury-classification standards. Inclusive of both fatal and non-fatal injuries, the results showed that most accidents happened in , , and (i.e., $50,000 or less). The main source of injuries manifested in (46%), followed by (19%), and (16%). The most frequent types of injuries were (31%), (27%), and (14%); the main injured body parts were (25%), (23%), and (18%). Among non-fatal cases, (37%), (36%), and (19%) caused most injuries; among fatal cases, was the leading cause of death (50%), followed by (28%) and (19%). The analysis also investigated the impact of several accident factors on the degree of injuries and found significant effects from such factors such as , , , , , and . In other words, the statistical probability of a fatal accident-given an accident occurrence-changes significantly based on the degree of these factors. The results of this study, as depicted in the proposed decision tree model, revealed that the most important factor for predicting the nature of injury (electrical or non-electrical) is: whether the source of injury is ; followed by whether the source of injury is . In other words, in predicting (with a 94.31% accuracy) the nature of injury as electrical or non-electrical, whether the source of injury is and whether the source of injury is are very important. Seven decision rules were derived from the proposed decision tree model. Beyond these outcomes, the described methodology contributes to the accident-analysis body of knowledge by providing a framework for codifying data from accident reports to facilitate future analysis and modeling attempts to subsequently mitigate more injuries in other fields.

BACKGROUND
Traffic accidents are among the most common causes of death. A small proportion of drownings are associated with traffic accidents. The roads in the Eastern Black Sea Region, where the study was conducted are fairly close to the seas, rivers, and ponds. This study aims to evaluate the cases who underwent autopsies after the traffic accident between 2009 and 2016 and who were found to have died as a result of drowning.
METHODS
A retrospective examination was made of the autopsy reports in the period 2009-2016.
RESULTS
As a result of the examination of forensic reports, from a total of 7124 autopsies performed in our center between 2009 and 2016, 41 (0.57%) were seen to be due to death in a traffic accident that resulted in drowning. Of the vehicles involved in the ac-cidents, 30 (73.2%) were retrieved from a river/stream, 7 (17.1%) from a lake, and 4 (9.7%) from the sea. In all 39 cases, the primary cause of death was determined as asphyxia related to drowning. Other reasons affecting death were traumatic intracranial bleeding in 7 (17.1%) cases, medulla spinalis injury in 4 (9.7%), and pulmonary injury in 2 (4.9%).
CONCLUSION
It was determined in the study that the typical autopsy results of trauma and drowning after a traffic accident could coexist. Drowning alone could be the cause of death, even though there was a traumatic origin such as a traffic accident in such cases. It was revealed that chemical and microscopic examinations should be handled together with crime scene results and eyewitness statements in addition to traumatic results during the examination phase.

BACKGROUND
Road traffic safety has considerably improved in China. However, the changes may differ in the economically backward and altitude higher western region. This study aims to investigate changes in the occurrence and severity of traffic casualties in western China and illuminate several key causal factors.
MATERIALS AND METHODS
Traffic accident data from the Annual Traffic Accident Statistics Report combined with population and vehicle data from the China Statistics Bureau between 2009 and 2019, were retrospectively analyzed. Traffic accident numbers, fatalities, human injury (HI), case fatality rates (CFR), mortality per 100,000 population (MRP), and mortality per 10,000 vehicles (MRV) were compared between the western and eastern regions. The HI, CFR, MRV, and MRP between the four groups based on the altitude of cities, below 500 meters, 500 to 1,500 meters, 1,500 to 3,000 meters, and over 3,000 meters, were compared using one-way analysis of variance. One hundred and seventy-eight cases of extremely serious traffic accidents were further analyzed in terms of accident occurrence time, vehicle type, road grade, road shape, accident pattern, and accident reason. The differences of accident characteristics between the eastern and western regions were compared using the chi-square test.
RESULTS
The number of traffic accidents and fatalities decreased in low-altitude areas in western China. However, there was a significant increasing trend in the high altitude area. The HI, CFR, MRV, and MRP were higher in the western region than that in the eastern and national. Those accident indicators tended to increase with increasing altitude. And there were statistically significant differences ( < 0.05) among groups from different altitudes. Chi-square test results show that there are statistically significant differences ( < 0.05) in term of road grade, road shape, accident pattern between eastern and western. Low-grade roads, combined curved and sloping roads, and rollover were significant features associated with traffic accidents in the western region. Bad roads were the main cause of rollover accidents in western China, which will lead to more serious casualties. Over speeding, overloading, bad weather, vehicle failure, and driver error were the top five accident causes.
CONCLUSION
Traffic accidents are increasing in high-altitude areas of western China, and they lead to more severe casualties. The characteristics of serious traffic accidents in this part of the country differ from those of the eastern regions. Improving road safety facilities, restrictions of speed, and improving medical treatment at accident scenes may be effective measures to reduce traffic accidents related injuries in the western region.

Review
OBJECTIVE
To examine the extent to which effective interventions to prevent unintentional child injury are reflected in the laws and regulations of China.
METHODS
We focused on the six common causes of fatal child injuries - drowning, road traffic injury, falls, poisoning, burns and suffocation. We investigated 27 interventions recommended by the United Nations Children's Fund, the World Health Organization or the European Child Safety Alliance. We searched China National Knowledge Infrastructure and Lawyee for Chinese legislations using keywords and synonyms for the 27 interventions. We reviewed the identified legislations for statements specifying the responsible implementation department.
FINDINGS
Seven national laws, nine regulations of the State Council and 46 departmental regulations were found to relate to at least one of the interventions. Although seven of the 27 internationally recommended interventions were covered by Chinese laws, 10 were not covered by any current Chinese law or regulation. None of the interventions against drowning and falls that we investigated was covered by national laws. The implementation responsibilities for effective interventions were either not specified or were assigned to multiple governmental departments in 11 or 20 legislative documents, respectively.
CONCLUSION
In Chinese laws and regulations, interventions proven to prevent major causes of unintentional child injuries are underrepresented and the associated implementation responsibilities are often poorly defined. China should include all such interventions in laws and regulations, and assign implementation responsibility for each to a single department of the national government.

BACKGROUND
The aim of the study was to evaluate the marine accident and incident reports between 2001 and 2012 by the Main Search and Rescue Coordination Centre (MSARCM). The method of the study was a descriptive-cross-sectional epidemiological study.
MATERIALS AND METHODS
The data of the research were composed of MSARCM's marine accident, incident and medical evacuation reports between 2001 and 2012. In the research, 1796 marine accident/incident reports were examined. The data were evaluated statistically by frequency distribution, univariate and bivariate regression analysis and multidimensional scaling analysis.
RESULTS
The highest number of cases in the study occurred in 2010 (n = 228, 12.7%). Considering the time of realisation of the cases, the highest number of cases occurred between 12:00 and 17:59 (n = 538, 30.0%). In the total of 1796 cases, there were 150 injured, 6046 rescued, 311 deaths, 202 missing and 73 patients. Considering the causes of accidents, the first three places were bad weather conditions (n = 287, 16.0%), human errors (n = 241, 13.4%) and machine malfunctions (n = 232, 12.9%). In the univariate and bivariate analysis of the data, it was seen that injuries in the Istanbul region were statistically more significant than those in the international region (8.5 fold, 95% confidence interval).
CONCLUSIONS
The risk management activities on injuries and accidents need to be carried out more carefully particularly in the areas with a high occurrence of marine accidents/events and medical evacuations (such as strait traffic, ports, shipyards), in the hotspots for shipping accidents.

Motion Shield is an automatic crash notification system that uses a mobile phone to generate automatic alerts related to the safety of a user when the user is boarding a means of transportation. The objective of Motion Shield is to improve road safety by considering a moving vehicle's risk, estimating the probability of an emergency, and assessing the likelihood of an accident. The system, using multiple sources of external information, the mobile phone sensors' readings, geolocated information, weather data, and historical evidence of traffic accidents, processes a plethora of parameters in order to predict the onset of an accident and act preventively. All the collected data are forwarded into a decision support system which dynamically calculates the mobility risk and driving behavior aspects in order to proactively send personalized notifications and alerts to the user and a public safety answering point (PSAP) (112).

INTRODUCTION
The aim of this paper is to understand the causes of occupational accidents in Spain's mining sector in order to propose action plans and improve future accident rates.
METHOD
This research analyzed a pool of data on 15,032 accidents occurring in the mining sector and reported to authorities between 2013 and 2018. Accidents are divided into three levels of severity: light, serious, and fatal. We study the influence of 12 variables on the accident severity rate in our sample.
RESULTS
The results show that accident severity is related to age, gender, nationality, length of service, economic activity, company size, accident location, days of injury leave, day of the week, deviation, injury, and specific Spanish region. This sector produces a high rate of serious accidents compared to all other sectors; has a male-dominated, older and experienced workforce; and employs mainly Spanish workers. Its activity is concentrated in larger companies and the work involves the use of heavy machinery and dangerous materials. We offer conclusions and future lines of research to help regulators, companies and workers to improve worker safety.

PROBLEM
Bicycle volumes are increasing in many regions worldwide leading to higher relevance of an in-depth understanding of bicyclist safety mechanisms. Detailed studies on bicyclist safety that consider exposure and distinguish by intersection category and crash types are missing for urban signalized intersections, which are of particular relevance for bicyclist safety.
METHOD
Based on a comprehensive dataset of motorist and bicyclist volumes and infrastructure characteristics for a sample of 269 signalized intersections in two German cities, we utilize a top-down approach to analyze firstly, bicycle crashes of all types and secondly, bicycle crashes by type including turning, right-of-way and loss-of-control. A combination of descriptive statistics and Accident Prediction Models (APM) are applied as analysis methods.
RESULTS
Bicycle volumes are relevant for all types of intersections and crashes, whereas the effect of motor vehicle volumes differ between these different applications. The separation of bicyclists from motor vehicles in time and space increases their safety but also leads to behavioral adaption and risk compensation. The likelihood of right-of-way crashes even increases with more separation in the signaling scheme. The main predictor for loss-of-control crashes in terms of infrastructure are tram tracks.
SUMMARY
This study provides insights on relevant determinants of bicycle crashes at urban signalized intersections at several levels of detail. Exposure variables as well as the physical separation of bicyclists from motor vehicles show consistent effects on bicycle crash numbers whereas the effects of signaling differ between crash types.
PRACTICAL APPLICATIONS
The different types of intersections and crashes follow each specific mechanism of bicyclist safety. The separation of bicyclists and motorists in time and space are paramount at intersections with high bicycle volumes. Risk compensation such as red light running becomes more important as intersections get smaller and motor vehicle volumes decrease.

INTRODUCTION
road traffic injuries represent accounts for significant cause of morbidity and mortality around the globe, particularly in developing countries like Ethiopia. Poor pre-hospital care system and delays in hospitals before getting aids added to the woes of mortality. However, there are no study that determine the types of injury, management and outcome of road traffic accidents and associated factors in this study area.
METHODS
a hospital based retrospective cross sectional study was conducted among patients attending to Adama Hospital Medical College with accidental injuries from January to December 2015. Data were retrieved from 556 patients registry selected by systematic random sampling from 11,120 injuries visiting the hospital. Data were coded, cleaned and entered to SPSS version 20 for analysis. Factors associated with the management outcome of injury related to road traffic accident were analyzed and statistical significance was declared with p < 0.05 with CI of 95%.
RESULTS
out of 556 trauma victims, 304 (54.7%) were due to road traffic accidents followed by personal violence (24%) and falling accident (10.3%). The majorities (74.8%) of patients were male and urban residents (55%). Soft tissue injury was the most frequent type of injury (51%) followed by extremity fracture and dislocation (26%). Delay to come to hospital (over 24 hours), severity of injuries and management types were factors influencing management outcome of injuries related to traffic accidents. About 90.1%, 4.6% and 5.3% of the patients were discharged without any prominent disability, permanent disability and died respectively.
CONCLUSION
road traffic accidents are preventable causes of morbidity and mortality. Practices of strict road safety measures and appropriate use of roadways by pedestrians should be in place, while establishing and strengthening early access to hospital and pre-hospital care to save life of injuries.

The chemical industry has made great contributions to the national economy, but frequent chemical plant explosion accidents (CPEAs) have also caused heavy property losses and casualties, as the CPEA is the result of interaction of many related risk factors, leading to uncertainty in the evolution of the accident. To systematically excavate and analyze the underlying causes of accidents, this paper first integrates emergency elements in the frame of orbit intersection theory and proposes 14 nodes to represent the evolution path of the accident. Then, combined with historical data and expert experience, a Bayesian network (BN) model of CPEAs was established. Through scenario analysis and sensitivity analysis, the interaction between factors and the impact of the factors on accident consequences was evaluated. It is found that the direct factors have the most obvious influence on the accident consequences, and the unsafe conditions contribute more than the unsafe behaviors. Furthermore, considering the factor chain, the management factors, especially safety education and training, are the key link of the accident that affects unsafe behaviors and unsafe conditions. Moreover, effective government emergency response has played a more prominent role in controlling environmental pollution. In addition, the complex network relationship between elements is presented in a sensitivity index matrix, and we extracted three important risk transmission paths from it. The research provides support for enterprises to formulate comprehensive safety production management strategies and control key factors in the risk transmission path to reduce CPEA risks.
