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.

Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.

This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as “lack of procedures for listening to opinions and preparing improvement measures” for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

This study examined the certification effects of safety and health management system (SHMS) on the establishment level of SHMS and accident statistics in construction industry. This study obtained the establishment level of SHMS for 106 construction companies surveyed from our previous study. In addition, three major accident statistics (mortality rate, accidental mortality rate, and injury rate) for the companies were collected from the database in Korean Occupational Safety and Health Agency. The statistical analysis results revealed that the establishment level for SHMS certified companies was significantly higher than those for uncertified or certification preparing companies. Furthermore, SHMS certified companies showed significantly smaller accident statistics compared to uncertified or certification preparing companies. The results of this study support the positive effects of SHMS on reducing major industrial accidents in construction companies.

The Act on the Punishment of Serious Accidents to Prevent Large-scale Disasters, including Ferry Sewol and Taean Thermal Power Plant, passed the National Assembly on January 8, 2021, and has been in effect since January 27, 2022. However, the law, in which the representative of the headquarters is unlimitedly responsible for each worker's accident, is somewhat unreasonable at a time when a company owns dozens to hundreds of construction sites due to the nature of the construction industry. I agree with the purpose of enacting the law to reduce chronic serious accidents at construction sites, but it is necessary to carefully reconsider the implementation of the law in that punishment alone cannot achieve industrial safety. Previous studies focused on revising the Occupational Safety and Health Act, but there are few studies on the impact on the construction industry after the implementation of the Serious Accident Act. Therefore, this study attempts to derive problems related to the application of the Serious Accident Act and present improvement measures. To this end, after analyzing previous studies, SWOT analysis was performed by applying the Delphi method to derive strengths, weaknesses, opportunities, and threats. In addition, the results of two surveys of safety experts such as public institutions, academia, and companies were reflected, and its countermeasures were presented as follows. S/O strategy: establishing on-site execution capabilities of health and safety management system; W/O strategy: expanding legal and system execution checks; S/T strategy: establishing a risk response system; W/T strategy: expanding consulting by external specialized institutions

The construction industry is considered to be a fatal accident industry, accounting for 28.5% of the total industrial accidents in 2017, as the number of industrial accidents in the construction industry has steadily increased over the past decade. So it is necessary to consider introducing Resilience Engineering, which is actively applied to risky industries around the world, to drastically reduce construction accidents. Although Resilience Engineering, which has emerged as the next-generation safety management centered on Hollnagel since the 2000s, claims the importance of strengthening Resilience abilities considering organizational structure and culture, most studies focus only on developing evaluation indicators. The purpose of this study is to analyze the impact of an organization's safety culture on its Resilience abilities in the construction industry. Specifically, it conducted empirical analysis on the impact of safety culture consisting of ‘communication, leadership and safety systems’ on the Resilience abilities(responding ability, monitoring ability, learning ability, anticipating ability), and the mediation relationship between leadership, communication, and safety system. The survey was conducted on construction workers, and an empirical analysis was conducted on the final 154 responses using SPSS 25 and Smart PLS 3. The results showed that the safety system had a significant impact on all Resilience Abilities, and communication had a significant impact on the remaining three except for anticipating ability among Resilience Abilities. On the other hand, leadership has been shown to have a significant impact on anticipating ability only. In the verifying of the mediation relationship between leadership, communication and safety systems, it was found that leadership affects all Resilience abilities by means of safety systems, but communication can only affect responding ability. This study has practical significance in that it suggests the need for policy-level efforts to introduce and apply Resilience Engineering and then expanded the effective safety management assessment of the construction industry in the future. Moreover, the academic implications are important in that the study attempted to expand the academic scope for a paradigm shift in the future as the safety culture has identified its impact on the Resilience abilities.

The recent domestic construction market is in a difficult situation due to reduction of the government's SOC budget and new orders from public-sector, and the deterioration of housing supply situation in the private sector etc. In addition, the number of disasters in the construction industry has increased in recent years with 26,570 people (up 5.7% from the previous year) in 2016, unlike other industries that are in a declining trend. As such, the construction industry has unique characteristics and problems such as high industrial accidents rate, abnormal subcontracting structure, excessive working hours and work intensity. As a result, the construction workers have a lot of job stresses. Job stress has been recognized as one of the major causes of industrial accidents and many researches have been conducted on that. However, most of the researches were about the factors that induce job stress and how these factors affect disaster occurrence, job satisfaction, job performance, turnover intentions, and job exhaustion. The purpose of this study is to investigate the effect of positive psychological capital on job stress, which is emerging as a new human resources development paradigm useful in corporate management in order to find ways to reduce job stress. To do this, 347 data collected from construction workers in Daejeon, Sejong, and Chungcheong provinces were analyzed using statistical package(IBM SPSS 22) for basic statistical analysis, reliability analysis, and regression analysis. As a result, positive psychological capital has shown an alleviate effect on job stress. In particular, the higher the optimism, hope, and resiliency of positive psychological capital, the lower the job stress. However, the higher the self - efficacy, the higher the job stress.

This thesis provides background information on DFS carried out by the government in an effort to reduce the accident rate, cases of DFS in other advanced countries to study their risk detection, risk assessment, risk control measures, and cases in which application of DFS during the designing phase succesfully led to reduction of the accident rate. Till now, the focus has been on incident responses after the occurance of accidents, it describes the importance of considering safety during the desining process through safety results and cases.

Abstract It has come to attention that a risk-assessing organization, that will benchmark a company’s safety department, is imperative, following an increase in large-scale SOC-business project, construction of higher-raised buildings, development of underground space; all that have increase accident rates. Having faced problems that arise in firms that demand diversity, complexity and instantaneity, the purpose of the thesis is to arrive at efficient and practical problem-solving means. In order to solve the problems that would surface theoretically during an actual risk assessment, the state of the operation systems of the top five national construction firms having a hazard rate of 0.25 times less than the average rate have been analyzed, while a hierarchal recognition research of the employees who not only function at the operating level but are the practice subjects of a firm, has also been conducted, bringing the main text.

건설현장에서 주로 사용하는 주요 가설기자재 규격에 대한 표준을 정하고 성능에 대한 신뢰를 확보하기 위하여 1992년 처음 도입된 가설기자재 성능검정제도는 2009년 안전인증제도로 변경되어 산업안전보건법 제34조(안전인증) 및 제35조(자율안전확인의 신고)에 근거하여 가설기자재 제조업체의 기술능력과 생산체계, 제품의 성능을 종합적으로 심사하고 안전인증기준에 적합 여부를 검증하여 안전인증표시(마크)를 사용할 수 있도록 하는 제도이다. 성능검정제도는 가설기자재 30종에 대해 제품의 성능만을 시험하여 합격증을 교부하였으나 2009년 1월 1일부터 의무안전인증 가설기자재 12종 33품목과 자율안전확인 신고 가설기자재 8종에 대해서 기술능력 및 생산체계와 제품의 성능을 심사하여 인증서를 교부하는 것으로 변경되었다. 가설기자재의 안전성 및 제품의 신뢰도 향상으로 건설공사 품질 및 안전이 확보됨에도 불구하고 일시적이며 부수적으로 사용되는 자재인 것으로 여겨져 가설기자재의 안전성 확보를 위한 관심과 노력은 매우 미흡하였다. 가설기자재에 대한 관심이 소홀한 가운데 안전성 여부를 확인하기 어려운 재사용가설재가 폭 넓게 사용되고 가설기자재의 가격경쟁이 심화됨에 따라 저가의 재료를 사용한 불법 가설기자재를 생산․유통하는 등 가설기자재 제도 전반에 불법적인 행위가 빈번히 이루어지고 있어 가설기자재 관련 제도와 제품에 대한 안전성과 신뢰의 문제가 다시 제기되고, 향후 가설기자재의 신소재(강화플라스틱 등) 및 신제품(접이식 틀비계 등) 등이 도입될 경우 현행 기준으로는 안전인증 또는 자율안전 확인을 받기 어려우므로 빠르게 진행되는 건설환경 변화에 적절하게 대응하지 못한다는 문제점 또한 제기되고 있다. 가설기자재 관련 문제점들과 제반 현황이 가설기자재를 제조하고 유통하고 사용하는 이해당사자간 신뢰를 잃고 있어 이해당사자간에도 제도 개선을 통한 가설기자재 시장의 정화와 개선이 필요하다는 공감대가 형성되고 있다. 따라서 정부는 가설기자재 관련 문제점을 종합적으로 검토하고 개선하기 위하여 다양한 방향으로 제도개선을 추진하고 있으며, 이와 같은 추진 대책의 일환으로 가설기자재 인증표시 기준에 관한 개선방안 마련을 위하여 가설기자재 생산․유통 및 사용 실태를 파악하고 가설기자재 관련 이해당사자 및 전문가의 의견 수렴 등을 통하여 가설기자재 인증표시 기준을 합리적으로 개선하고 효율적으로 관리하기 위한 연구가 필요하게 되었다. 본 연구를 통해 국내 건설산업에서 중요한 역할을 분담하고 있는 가설기자재의 안전성 향상과 신뢰성 회복을 위한 합리적인 개선방안을 도출하여 산업안전보건법령의 제‧개정에 반영할 필요가 있다.

The domestic construction market is in a difficult situation due to the recent decline in government SOC budgets, sluggish new orders from large public corporations, and deteriorating housing supply conditions in the private sector. In addition, construction workers compared to other industries have higher levels of job stress due to higher non-regular workers, unstable and irregular working hours, high work intensity, and poor work environment. According to previous research results, high job stress of construction workers has a great impact on the occurrence of disasters, and it is urgently needed to improve the job stress. The purpose of this study is to investigate the effect of Positive Psychological Capital such as positive self - efficacy, optimism, hope and resilience on job stress. Based on the results of this study, we suggest a plan to reduce job stress of construction industry workers.

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.

Many industrial accidents have occurred continuously in the manufacturing industries, construction industries, and service industries of Korea. Fatal accidents have occurred most frequently in the construction industries of Korea. Especially, the trend analysis of the accident rate and fatal accident rate is very important in order to prevent industrial accidents in the construction industries systematically. This paper considers forecasting of the accident rate and fatal accident rate with static and dynamic time series analysis methods in the construction industries. Therefore, this paper describes the optimal accident rate and fatal accident rate by minimization of the sum of square errors (SSE) among regression analysis method (RAM), exponential smoothing method (ESM), double exponential smoothing method (DESM), auto-regressive integrated moving average (ARIMA) model, proposed analytic function model (PAFM), and kalman filtering model (KFM) with existing accident data in construction industries. In this paper, microsoft foundation class (MFC) soft of Visual Studio 2008 was used to predict the accident rate and fatal accident rate. Zero Accident Program developed in this paper is defined as the predicted accident rate and fatal accident rate, the zero accident target time, and the zero accident time based on the achievement probability calculated rationally and practically. The minimum value for minimizing SSE in the construction industries was found in 0.1666 and 1.4579 in the accident rate and fatal accident rate, respectively. Accordingly, RAM and ARIMA model are ideally applied in the accident rate and fatal accident rate, respectively. Finally, the trend analysis of this paper provides decisive information in order to prevent industrial accidents in construction industries very systematically.

Full embroidery industrial accidents in recent years has shown a declining trend. But disaster embroidery of domestic construction industry were more than 20,000 deaths per year is about 500 people. The government has introduced a construction site often changing the recruitment of new construction based on health and safety as an alternative to road safety education training yisuje of construction workers, daily work periods short. Certificate of Basic OSH Training in Constructions had also been evaluated as successful by reducing the accident rate problem. It is conducted in private educational institutions has occurred on the friction between workers and employers and training costs are difficult to approach workers in the education standards for such facilities due to the superintendent. Educational institutions are institutions that have been caused by excessive competition lowered levels of education. There is also a lack of evaluation that the training is limited to the basic safety knowledge. These details are brought formal safety education purposes only and is introducing the results of other self jyeotgi difficult to reap the proceeds to good effect. In this study, we propose a plan for improving operational problems and enemy status based on research data presented after the Certificate of Basic OSH Training in Construction.

Occupational Safety and Health Expenses Law in construction industry was enacted in 1988 by the notification of Ministry of Employment and Labor and 22 revisions have been made since. The fact that revisions have been made almost every year since the first enactment shows that Occupational Safety and Health Expenses can effectively prevent construction accidents and the need for revisions to fit the reality has been raised continuously. Despite the construction industry has undergone various internal and external environmental changes, (such as the changes in the safety and health management techniques and the increase in the construction employees’ desire for safety) the appropriation standard of Occupational Safety and Health Expenses has been calculated based on the contract price. The construction industry has constantly suggested that the Occupational Safety and Health Expenses be calculated based on the estimated construction expenses since applying the current method doesn’t provide enough money to secure the safety. Also because it has become mandatory to hire a health manager since 2015, the lack of Occupational Safety and Health Expenses is expected to get worse. In this study, we will analyze the usage of Occupational Safety and Health Expenses and propose a more practical and realistic change in setting the appropriation standard of Occupational Safety and Health Expenses.
