The construction industry stands out for its higher incidence of accidents in comparison to other sectors. A causal analysis of the accidents is necessary for effective prevention. In this study, we propose a data-driven causal analysis to find significant factors of fatal construction accidents. We collected 14,318 cases of structured and text data of construction accidents from the Construction Safety Management Integrated Information (CSI). For the variables in the collected dataset, we first analyze their patterns and correlations with fatal construction accidents by statistical analysis. In addition, machine learning algorithms are employed to develop a classification model for fatal accidents. The integration of SHAP (SHapley Additive exPlanations) allows for the identification of root causes driving fatal incidents. As a result, the outcome reveals the significant factors and keywords wielding notable influence over fatal accidents within construction contexts.

In the past, measures for the reduction of industrial accidents has led the safety and health policy of construction sites by the guidance, supervision and the regulation according to「Occupation Safety and Health Act」handled by Ministry of Employment and Labor (MOEL). Nowadays companies realize that due to the factors such as diversification of employment types, outsourcing of hazardous work, new construction method and complicated types of construction, etc., there is a limit on safety management for construction sites as far as it is passively led by the governmental safety management policy and regulation. In this study, in order to practice the autonomous safety management escaping from the government-led safety management, improvement plans are proposed and applied by analyzing the basic cause of the all kinds of fall accidents that could possibly occur in the apartment construction sites and by verifying the hazardous factors and risks by fields.

The purpose of this study is to investigate the factors and effects of job stress of construction workers on construction accidents and turnover intention in order to improve the field work environment of construction industry which shows higher industrial accidents than other industries. To this end, research models and hypotheses were established based on previous research, and the questionnaire was distributed to 10 construction companies in Daejeon, Sejong, and Chungcheong provinces. The 301 data collected were performed statistical analysis such as basic statistical analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, and logistic regression analysis using the statistical package (IBM SPSS 22). The results of this study are summarized as follows. First, job stress has a significant effect on accident occurrence. Among the sub-factors of job stress, there was positive (+) influence on work culture and relationship conflict between peers, and organizational system had negative influence. Job demands, compensation incompetence, and job instability were not statistically significant. Therefore, it is necessary to concentrate on the factors of work culture, organizational system, and relationship conflict in the construction site. Second, job stress has positive effect on turnover intention. Job stress, inadequacy of compensation, and work culture were positively related to turnover intention. Third, job demands have a slightly greater impact than compensatory inadequacies. The factors that make the job turnover more important are the excessive job burdens such as respect, internal motivation, responsibility rather than expectation non-conformity, time pressure, increase of work load. Therefore, in order to reduce the turnover intention of the construction worker, it is necessary to pay attention to improvement of the job requirement. Fourth, the worker’s job stress could overcome by exercise and fatigue elimination, work environment management, and self-opening for others. It is necessary to establish a work environment management system for counseling and intimacy formation to open up the exercise and fatigue relief program of the workers at the construction site and to open themselves between the workers and the supervisors.

In the construction sites, rush (speedy construction) work have recently been overused because of budget reductions by reducing the construction duration after the long-term economic recession and construction business stagnation with institutional change including the instruction of the duration shortening bidding system and the introduction of the post-construction sales system by the Korea Research Institute for Human Settlements. Due to this, negligent accidents have frequently occurred by forcing manpower, equipment, finance, and material procurement and pressing ahead with impractical construction wok at night according to the reduction of construction schedules. Therefore, this paper has the necessity of this study to seek for alternatives to prevent negligent accidents by finding factors related to rush work in the reality that the importance for preventing negligent accidents is more emphasized while they have not been reduced in construction sites.

Many fatal and non-fatal injuries occurred as a result of unexpected falls from horse scaffolds during structural or finishing works such as painting, plastering, or plumbing. Therefore, this study is to improve safety standards for horse scaffolds used mostly in the interior finishing works. But hazard elements for the horse scaffolds has not been specifically identified. This study has analyzed the accidents of horse scaffolds to prevent construction accidents and the characteristics of a serious accidents related the horse scaffolds. It was suggested a safety management plan and a group of accidents characteristics. The results of this study are expected to be utilized as basic data for prviding a reference related to the horse scaffolds and to be unified the regulations associated with the horse scaffolds.

Recent News patrons of incidents can be called sinkhole that occurred one after another (Sink Hole). Due to this anytime, anywhere I do not know how the land is turned off worry and anxiety is the reason why you can never be dismissed as exaggerated. As we have seen today through the video, the vehicle was traveling on a road or pedestrian who was walking down the street they look out of the basement of a sudden they still come to mind vividly. Here, examples and corresponding measures to prevent the sinkhole off the ground, including the causes and impact on society because of this that occurred, and policy measures and abroad are evaluated with respect to what it is.

Recently, the domestic air construction site is shortened rapidly, Ltd. is inevitable for reasons such as reduced air according to client's demands have been made. Accidents that occur during rapid construction is a situation that occurs accordingly indispensable. In the rapid construction and a study about the impact on safety and prevention measures and to contribute to accident prevention.

Recently, the Ministry of Employment and Labor Management is a trend to strengthen all men death rate than the accident rate. Points reduction in the accident rate change orders related to credit rating score to +2 points in his plans as part of +1 point. In addition, according to the fancy linger RISK treatment in the event of a disaster site and fiction treatment to achieve accident-free during processing the scene interspersed with equity issues have been raised. In general disaster for the problem in the first two cases occurs when abnormal process according to the disaster site manager positions dismissal policy, each division headquarters itself, interspersed disasters performance compared to processing in accordance with the refrain, processing expenses in accordance with the composition of untreated industrial accident, costs and burdens partners FTC , there is a possibility that the issues raised, such as the Ministry of Employment and Labor. In response to domestic social practices focused on the construction site practices and prevention measures should be evaluated with respect to what.

Total accident rate in the construction industry is a very meaningful reduction to establish a comprehensive disaster reduction measures, including through the Survey, the disaster prevention projects whilst driving status and problem analysis in order to reduce the mature workers in the construction industry is growing rapidly in all disaster disasters (share) The days. It is urgent to establish a framework and measures that can identify the specific cause for this than for the middle-aged workers and disaster reduction in disaster reduction efforts, which continue to increase. Used as measures of information and data presented in the basic requirements of mature workers also been.

The large-sized, complex, and multi-storied construction industry caused the increasing construction amount together with insufficient skilled workers to increase the probability of occurring accident , resulting in the most construction accidents next to manufacturing industry. Death accidents have risen to serious level, compared construction industry with manufacturing industry along the numbers of workers. Due to the main feature of one-time industry receiving orders, open-air dispersed production activity and the long-complex production process, the continuous efforts to prevent and manage safety accidents were made but the results were of no effect. They didn't deeply analyze the falling accidents that consist of half death accidents in construction industry. This study has classified in detail Missteps, Slip, Trip, Unstability and the others on the basis of gait characteristics, occurrence types, frequency and intensity of death accidents. This study suggested the effective methods on the construction safety management according to the causes of falling accidents. This study will be expect to be used as the basic data in the procedure and the program of safety management.

Share of total accidents in construction accidents construction site accident 70% of small embroidery Reducing the rate of Construction of the entire construction accidents decreased overall is a very meaningful work. Disaster reduction continues to increase despite the efforts of a small construction site(Amount less than 2,000,000,000) for Disaster Reduction In order to identify more clearly the cause of the system and provide the urgently needed measures.

Construction victims have increased year by year. Disaster proportion is also increasing continuously. Looking over the causes of disasters by each type of work, fall from working platform indicate the highest rate above all so that it is urgently required to set up safety measures. This study is to grasp the present status of construction accidents, to identify areal characteristics of the top 20% accidents on the basis of working platforms with the highest accident rate, to grasp the causes of accidents after their analyses, and to present methods to reduce casualties related to working platforms. As measures to reduce construction disasters, this study proposes to improve safety management and training on working platforms, to complement safety regulations, and to better performance including the development and expansion of certified products suitable for safety regulations.

The scale of construction industry recently tends to become bigger and larger in line with development of construction technologies and methods. Although increasing usage of construction machinery has led to improving productivity, reducing schedule and cost, constructions workers have been exposed to unstable work environment, causing more and more accidents. Construction machinery-related laws and regulations has not been enacted and reflected the conditions and circumstances of the construction industry in a timely manner. A various construction machinery and equipments produced and changed in structure randomly are so widely used that related-accidents may occure gradually. Propose a plan for accidents prevention through the analysis of characteristics and cases on construction machinery-related accidents over the past five years from 2009 to 2013.

There has been an increase in fire/explosion accidents caused by chemical substances used in new small/medium sized construction, reconstruction, or extension sites. There is vast room for improvement, especially in safety training, safety inspection, and selection of countermeasures because training, technicality, and management systems regarding fire·explosion risks in small/medium sized construction sites are very immature in most cases. The purpose of this study is to propose a differentiated technical, educational, and management application plan for preventative management of fire·explosion accidents caused by chemical substances used in small/medium sized construction sites.

The consequences of rapid industrial advancement, diversified types of business and unexpected industrial accidents have caused a lot of damage to many unspecified persons both in a human way and a material way Although various previous studies have been analyzed to prevent industrial accidents, these studies only provide managerial and educational policies using frequency analysis and comparative analysis based on data from past industrial accidents. The main objective of this study is to find an optimal algorithm for data analysis of industrial accidents and this paper provides a comparative analysis of 4 kinds of algorithms including CHAID, CART, C4.5, and QUEST. Decision tree algorithm is utilized to predict results using objective and quantified data as a typical technique of data mining. Enterprise Miner of SAS and AnswerTree of SPSS will be used to evaluate the validity of the results of the four algorithms. The sample for this work chosen from 19,574 data related to construction industries during three years (2002~2004) in Korea.

The purpose of this study is to provide client safety and health management duty in the construction industry. Most regulations did not give direct roles and duty to client in construction industry. As a result of the survey on construction workers who have the greatest influence on the prevention of industrial accidents, the clients and constructors chose contractor the most. Safety managers and supervisors chose client the most. Therefore, it is necessary to manage safety and health centered on the client in order to prevent fundamental disasters.

This study aims to suggest the available additional education courses that can be combined with the existing functional education, which is mainly for the enhancement of safety consciousness, along with a model for the way of management. To achieve the purpose of the study, the construction death accidents for the recent five years were analyzed about their patterns and the scales of the accident sites to infer the main subjects and the direction of hands-on education courses. Based on the analysis results, the recombination and management plans for the construction safety hands-on education courses and the additionally required education courses were proposed.
