Construction accidents result from a combination of factors, including both the actions of workers and the safety conditions on site. Despite advancements in enhancing construction site safety, there remains a gap in comprehending the cognitive processes underlying workers' unsafe behavior. This paper investigates and validates a qualitative model that delves into the potential causes of workers' unsafe actions by examining their cognitive processes, employing a system dynamics approach. By analyzing the interplay of various loops within this model, it offers both short- and long-term safety strategies for managers intent on minimizing unsafe behavior among workers. Specifically, safety managers should prioritize increasing workers' awareness of hazards through education and fostering a positive safety mindset. Moreover, they should task frontline supervisors with directly addressing and rectifying instances of unsafe behavior by workers. Lastly, construction safety managers ought to formulate safety strategies that take into account the cognitive states of workers to mitigate any adverse consequences of biased safety management. The outcomes of this research contribute to our comprehension of methods to enhance hazard perception among workers, curtail unsafe actions, and ultimately reduce construction accidents from a cognitive standpoint.

This study was conducted to present the improvement in professional perception among construction workers engaged in domestic construction sites by analyzing the reality of their professional perception. The results are as follows: First, with regard to professional perception of the construction industry, managerial workers made their positive reply to items regarding construction and construction workers but had their negative attitude towards construction as a job and as a recommendable job for others; whereas production workers showed their negative reply to all the items. Second, with respect to factors for construction being firmly regarded as an 3D industry, managerial workers selected 'long working hours' and production workers replied with 'low wages and income insecurity.' Third, as for improvement activities for professional perception of construction, most of construction workers simply knew about activities being performed but expressed their intention to participate in the activities.

In road work zones, pedestrian workers' habituated inattention to warning alarms from construction vehicles can lead to fatal accidents. Previous studies have theorized that human factors such as personality traits may affect workers' inattentiveness to workplace hazards. However, there has been no study that directly examined how road construction workers' personality traits affect their attention to warning alarms within a work zone and the likelihood of engagement in a struck-by accident. This study examines how workers' sensation-seeking (especially boredom susceptibility) is related to inattention to warning alarms while performing a task in road work zones. An experiment with actual road construction workers was conducted using a virtual road construction environment. Workers' attention to repeatedly presented warning alarms was measured using eye-tracking sensors. In response to workers' frequent inattentive behaviors, a virtual accident was simulated. Results revealed a significant association between boredom susceptibility and workers' engagement in the virtual accident, a consequence of inattentiveness to warning alarms. The findings suggest that workers' personality traits predispose them to tune out warning alarms and become vulnerable to accidents in road work zones. The findings of this study can be used to develop targeted interventions aimed at preventing workers' inattention to repeatedly exposed workplace hazards, thereby contributing to reducing fatal accidents in road work zones.

Current trends in the Korean construction industry, including the aging of the workforce, a lack of new Korean construction workers, and an inflow of unskilled foreign labor, have caused a range of problems, including quality deterioration, reduced productivity, insufficient understanding of the function and difficulties in communication, to name a few. Yet while countermeasures to these problems should be based on accurate and diverse fundamental data, including the current status of demand and supply of domestic and foreign construction workers, the perception of construction workers, studies on these questions have, thus far, been scarce. For these reasons, this study was conducted using a questionnaire for managers and workers on construction sites, to secure fundamental data relating to construction workers. The findings of the survey showed that it is urgent to prepare measures to educate, train and foster human resources, considering the aging of the construction workforce and the lack of an inflow of new construction workers.

Recently unemployed construction workers are increasing because of construction recession. But the lack of manpower occurs at the same time, in construction sites. So, the excess of workforce supply and demand exists in construction sites. Construction companies have a difficulty in seeking young skilled workers due to this problem. In this study, construction accidents reported by Korean Occupational Safety and Health Agency from 2007 to 2010 were analyzed. It has shown that 50-54, 45-49 and 55-59 year old workers formed 22%, 18% and 17% respectively. This means that old workers becomes a real problem in construction. This research has shown that old workers didn't have much more accidents than young workers, construction accidents related to the employment period of workers.

The construction workers might be at the risk of many occupational injuries and illnesses. To protect workers from various hazards, industrial health and hygiene systems were specified for the construction workers by law. It is important to know the actual health and safety(H&S) conditions by tasks and the characteristics of injuries and illnesses of construction workers. This study was designed to investigate the actual conditions of construction workers exposed to various harmful substances and work elements including evaluation of health status of each worker and general H&S system. Questionnaire was sent to 600 construction workers nationwide and totally 367 people responded to it having 61.67% of response rate. The common construction hazards were dust(29.6%), noise(19.3%), repetitive motions(12.0%), handling excessive heavy materials(11.2%) in order. The repetitive motions and handling heavy materials related to muscle disorders accounted for 23.2%. The accident and injury types were in order of overexertion, falling, overturning, dropping or flying, electric shock, collision, etc.

Construction work is a labor-intensive industry, which is required systematic production activities using materials, manpower, and equipment. Among them, manpower resources play a very important role in achieving efficiently production in the organization. Construction work is highly dependent on construction craft workers, and the level of proficiency can be directly related to the construction productivity and quality. However, a rapidly aging construction craft workers in Korea, is being replaced by a foreign construction craft workers because of advoidance of new laborers in the construction site. In the future, if the continuous development and management of construction manpower is not made properly, it may be lead to adverse effects such as setbacks in production, delayed completion, faulty construction, industrial disasters, and decreased productivity in construction site. In this study, it was proposed four important factors for work capacity management of construction craft workers. These were ensuring of physical strength through the health management of construction craft workers, securing of proficiency through career management, ensuring of productivity through work capacity and establing of informatization through work capacity management. By introducing a systematic system, it is possible to improve construction craft workers' professionalism, enhancing the level of welfare, reflecting the realities of labor costs, increasing the quantitative and qualitative levels of construction craft workers, Futhermore it was demanded the continued interest and policy support for the realization of effective management of construction craft workers.

The construction industry has a higher dependency on manpower than other industries, requiring a supply of high quality skilled workers. But negative perceptions regarding the construction industry have continued to reduce the inflow of young workers into the industry, and the existing skilled workforce is aging. In response, as a solution for training young construction skilled manpower, training programs for young construction skilled workers have been implemented by specialized high schools. But the current status of career paths chosen by the graduates of these specialized high schools did not show a substantial influx of workers into the construction industry. In this regard, with the purpose of promoting an influx of young construction skilled manpower into the industry, this study analyzed the goals and problems of construction education in specialized high schools in South Korea, and suggested a method for improvement.

The construction industry is an industry in which skilled construction workers should be secured and trained because of the quality and productivity of buildings, but the negative image makes it difficult to supply and demand skilled construction workers. In response, this study derived the factors influencing the intention of transferring construction workers to other occupations and investigated ways to improve the prevention of leaving other occupations by age of construction workers. The factors influencing the turnover of construction workers have also been derived, and work overload, salary, workplace stability, and employment competitiveness have a significant impact on the intention of new employees to change jobs. According to a survey on ways to improve the prevention of leaving other jobs, those in their 20s and 30s are "improving working conditions, such as providing holidays, paying overtime, compliance with working hours," and those in their 50s and 60s.
