Abstract: The Civil Construction Industry (CCI) is a globally recognized industry with a high incidence of workplace accidents and fatalities. Despite extensive research, few studies have focused on this subject in less developed regions of Brazil, such as the Amazon. In addition, the majority of these studies have focused solely on descriptive models, neglecting inferential statistical techniques that contribute to the study's predictive value. Thus, the purpose of this study is to investigate the relationships between the variables associated with accidents at work in the CCI, as well as the probabilities of lesions and their types in a Brazilian Amazon state. In addition to descriptive analyses, logistic regression models were developed to identify the types of lesions and the odds oftheir occurrence, which were associated with accidents resulting from a variety of independent variables. The most relevant findings indicate that lesions are more likely to occur in the final phases of the construction site, with fracturebeing the most likely to occur and those aged 18 to 24 who work with machines, equipment, and vehicles being the most likely to be affected. The findings of this study will contribute to the theoretical development of this research line, as well as the improvement of worker safety and health programs, reducing risks and enhancing workplace organization in the CCI.

Abstract: Background
Since the Republic of Korea became a labor-force-importing country, the number of foreign workers has increased gradually, especially in the construction industry. The main objective of this study was to examine the differences in safety perception between domestic and foreign workers at Korean construction sites.
Methods
A total of 891 Korean and foreign workers were surveyed: 140 foreign and 751 Korean workers. The general characteristics and 25 factors influencing safety perception were considered in the questionnaire. Regression and correlation analyses were conducted to examine the variables of workers' safety perception.
Results
Differences of nationality (F = 7.379, p < 0.001) and workplace accidents were statistically significant for both domestic (F = 1.503, p < 0.05) and foreign workers (F = 7.868, p < 0.05). In contrast, age, education, and Korean language level were significant variables only for foreign workers. Correlation coefficients of 0.428** for Korean and 0.148 for foreign workers between two items – namely, “management's commitment to safety” and “blaming staff when they make mistakes” – support the conclusion that foreign workers do not trust management's commitment to safety, while Korean workers have confidence in these commitments.
Conclusion
Foreign workers' level of safety perception should rise to the same level as Korean workers, especially in terms of obeying safety rules, safety education performance, and safety beliefs. Therefore, an improvement plan for the Korean construction industry is suggested in order to have a better safety level at construction sites with foreign workers.

Abstract: The law and various systems are necessary to efficiently manage safety in the construction process. However, policy almost always focuses on the contractor stage because of the high risk of accidents. The objective of this study is to suggest practical roles to reduce construction accidents by considering the organically linked characterization of each stage (client, designer, supervisor, and contractor) in construction to realize preventive policies. First, the Construction Technology Promotion Act and Occupational Safety and Health Act, overarching laws in South Korea applicable to construction safety, are reviewed. Next, the basic implemented roles of each stage are summarized to satisfy safety and health activities. Subsequently, a questionnaire is developed to diagnose the implementation level under current conditions using multiple-choice questions to easily gather responses and short answers. The survey was conducted with the safety coordinators (clients, designers, supervisors, and contractors) to determine their rates of accidents, contracting rankings, recommendations by the council, and ease of access. Through the surveying results, the current status of South Korea's construction safety system is examined, and rational roles to interconnect the various elements of this system are suggested. This study is significant because it investigates the safety level of the construction life cycle. Our suggestions are expected to play a critical role at each construction stage in reducing the accident rates of construction in South Korea.

Abstract: Major accidents in the chemical process industries are relatively rare, but the resulting harm to workers, property loss, business interruption, and the environment are very serious. This study investigates chemical accidents that occurred between January 2008 and June 2018 in South Korea, and proposes ways to prevent similar accidents from occurring by analyzing the main causes of these accidents. Nine core concepts were drawn from the analyses comparing chemical accidents in South Korea: (1) current casualties by type of worker, (2) how the scale of the enterprise affects the disaster, (3) chemical accidents by type of occurrence, (4) analysis of ignition sources, (5) chemical accidents by CPI facilities, (6) human and technical error, (7) chemical accidents by work situation, (8) chemical accidents by non-compliance of process safety management (PSM) standards, and (9) chemical accidents by hazardous materials. Although there have been no recent occurrences of large chemical accidents since 2017 due to various factors, our results indicate that the past frequency of such accidents area serious concern in South Korea. Understanding the root causes of these accidents can help to prevent the recurrence of similar accidents and to strengthen preventative measures in chemical plants.

Abstract: Background
The study was conducted to investigate the current status of the occupational health and safety management system (OHSMS) in the construction industry and the effect of OHSMS on accident rates. Differences of awareness levels on safety issues among site general managers and occupational health and safety (OHS) managers are identified through surveys.
Methods
The accident rates for the OHSMS-certified construction companies from 2006 to 2011, when the construction OHSMS became widely available, were analyzed to understand the effect of OHSMS on the work-related injury rates in the construction industry. The Korea Occupational Safety and Health Agency 18001 is the certification to these companies performing OHSMS in South Korea. The questionnaire was created to analyze the differences of OHSMS awareness between site general managers and OHS managers of construction companies.
Results
The implementation of OHSMS among the top 100 construction companies in South Korea shows that the accident rate decreased by 67% and the fatal accident rate decreased by 10.3% during the period from 2006 to 2011. The survey in this study shows different OHSMS awareness levels between site general managers and OHS managers. The differences were motivation for developing OHSMS, external support needed for implementing OHSMS, problems and effectiveness of implementing OHSMS.
Conclusion
Both work-related accident and fatal accident rates were found to be significantly reduced by implementing OHSMS in this study. The differences of OHSMS awareness between site general managers and OHS managers were identified through a survey. The effect of these differences on safety and other benefits warrants further research with proper data collection.

Abstract: Background
Headache/eyestrain symptoms are common health problems that people experience in daily life. Various studies have examined risk factors contributing to headache/eyestrains, and physicochemical exposure was found to be a leading risk factor in causing such symptoms. The purpose of this study was to examine the relationship of headache/eyestrain symptoms with physicochemical exposure among Korean construction workers depended on worksite.
Methods
This study used data from the 4th Korean Workers Conditions Survey and selected 1,945 Korean construction workers as participants. Multivariable logistic regression analysis was used to determine the relationship.
Results
Exposure to vibrations among all construction workers affected the moderate exposure group [odds ratio (OR) 1.53, 95% confidence interval (CI) 1.01–2.32], the high exposure group (OR 1.77 95%CI 1.17–2.67), and the indoor high exposure group (OR 1.61, 95%CI 1.02-2.55) and among outdoor construction workers, the moderate group (OR 6.61, 95%CI 15.4–28.48) and the high group (OR 6.61, 95%CI 1.56–27.98). When exposed to mist, dust, and fumes, the indoor high exposure group was significantly affected (OR 1.63, 95%CI 1.07–2.47). All construction workers exposed to organic solvents were affected, high exposure group (OR 1.69, 95%CI 1.15–2.49) and indoor high exposure group (OR 1.77, 95%CI 1.08–2.89). The high exposure group in all construction worker (OR 1.70, 95%CI 1.20–2.42) and the indoor high exposure group (OR 1.83, 95%CI 1.17–2.89) also were affected by secondhand smoking exposure.
Conclusion
Many physicochemical exposure factors affect headache/eyestrain symptoms among construction workers, especially indoor construction workers, suggesting a deficiency in occupational hygiene and health environments at indoor construction worksites.

Abstract: Although industrial accident rates are gradually decreasing in Korea, the construction industry's accident rate is still higher compared with other industries. Human errors, mentally unstable workers, insufficient safety training, and safety policy affect the occurrence of construction accidents. Owing to the characteristics of this industry, occupational accident types, such as fall from height, collision with objects, rollover, and those due to falling objects, can be related to the weather data. Therefore, to reduce and prevent occupational injury, it is necessary to classify and predict occupational accident types in detail. In this study, we built a model to classify and predict occupational accident types using a random forest (RF). We extracted important factors that affect the occupational accident types at construction sites using feature importance, and we analyzed the relationship between these factors and occupational accident types. The accuracy score of the RF model was obtained as 71.3%, and we presented key construction safety factors considering the feature importance. For future research, we will collect data and develop models to predict occupational accident types in real-time. Real-time construction accident prediction research will reduce accident at construction sites.

Abstract: Background
The objective of this study is to identify high-risk groups for industrial accidents by setting up 2003 as the base year and conducting an in-depth analysis of the trends of major industrial accident indexes the index of industrial accident rate, the index of occupational injury rate, the index of occupational illness and disease rate per 10,000 people, and the index of occupational injury fatality rate per 10,000 people for the past 10 years.
Methods
This study selected industrial accident victims, who died or received more than 4 days of medical care benefits, due to occupational accidents and diseases occurring at workplaces, subject to the Industrial Accident Compensation Insurance Act, as the study population.
Results
According to the trends of four major indexes by workplace characteristics, the whole industry has shown a decreasing tendency in all four major indexes since the base year (2003); as of 2012, the index of industrial accident rate was 67, while the index of occupational injury fatality rate per 10,000 people was 59.
Conclusion
The manufacturing industry, age over 50 years and workplaces with more than 50 employees showed a high severity level of occupational accidents. Male workers showed a higher severity level of occupational accidents than female workers. The employment period of < 3 years and newly hired workers with a relatively shorter working period are likely to have more occupational accidents than others. Overall, an industrial accident prevention policy must be established by concentrating all available resources and capacities of these high-risk groups.

Abstract: After the hydrogen–fluoride release accident in 2012, the Korean society realized the importance of chemical safety and many plans have been proposed to improve it. After the big chemical accident, the “Chemical Control Act” was newly established. The law of the “Chemical Control Act” is the most representative measure for chemical safety. According to the law that came into force in 2015, all chemical dealing companies must conduct an off-site consequence analysis of their chemicals and develop a plan for risk management. To reduce off-site consequences from the chemical plant, an innovative risk-management plan was suggested by the Korean industry. A decision was made to build a 30 m high mitigation barrier outside the plant area to protect the public when a chemical release accident occurs. The construction is now under process, and two representative accident scenarios are developed for its simulation to confirm the effect of mitigation barrier. Each scenario follows guidelines of the “Chemical Control Act,” and simulation results show that the barrier helps reduce chemical concentration in the public area. This plan is expected to improve the anxiety of residents near the plant and will be a good example of risk management in the industry.

Abstract: This study is aimed at exploring the characteristics of fatal occupational injuries in Korea’s construction industry and comparing the causes in various occupations within that industry. There were 10,276 fatal occupational injury victims in Korea over 8 years (1997–2004). The mortality risk due to injuries in construction and non-construction industries was calculated, and their causes were compared. The number of victims of fatal occupational injuries in the construction industry was 4333 (42.2% of the total fatal occupational injuries), and the 1 year mortality risk was higher (23.7/100,000 persons) than in non-construction industries (10.4). Falling was the most frequent (52.7%) cause of fatal injuries. In addition, deaths due to structural collapse and electric shock were significantly higher than in other industries. When the distribution of the causal factors in various occupations within the construction industry was investigated, some factors appeared more frequently in certain occupations than in others. As the construction industry encompasses a large proportion of occupational injuries, a reduction in this field alone will substantially contribute to an overall reduction of occupational injuries in Korea. Further research for effective prevention is needed.
