This study investigates the virtual reality (VR) simulation to train construction workers for modular construction. Recently, the construction industry has been experiencing a growing demand for modular construction due to a shortage of labors and an increasing social need for safety. While the demand for modular construction has been increasing, construction labors suffer a basic knowledge regarding modular construction. The users of the simulation, developed by Unity program and Oculus Quest 2, experience the removal of hazardous elements at the location whether the modular unit suspended by a crane is lowered, the lowering and assembly of units through crane operation, and the fall from the roof which is the most frequent accidents in modular construction. The simulation was tested by 15 subjects. The effectiveness of the education was measured through a survey on self-efficacy, perceived usefulness, usability, and presence. It was found that the VR training is suitable for educating on the modular construction activities and safety issues related to them. This study also found that perceived usefulness is the factor that has the greatest impact on self-efficacy. This study can contribute to resolving the labor education issues for the deployment of modular construction.

Professional TBM Operator is in short supply worldwide, and insufficient construction experience of new personnel using TBM can lead to a decline in response capabilities when various construction risks occur. The fact that the TBM construction quality greatly depends on the skill and experience of the TBM operator, and the decrease in productivity due to insufficient skilled manpower, and the decrease in safety due to the decrease in skill level are frequently discussed problems in the TBM industry. To this end, several overseas companies and organizations have developed simulators, and a simulator is being developed in Korea. The International Tunneling Association is planning a comprehensive training, including classroom training, e-learning, simulator training and field training. Given the progress at home and abroad, TBM driver training and formal recognition of training through certification or licensing is expected to become the norm in the near future.

This study has provided the answer which construction companies to make complete competitive factors for sustainable growth in construction industry with to 21C environment changes. So the purpose of study is to provide a guideline for establishing the strategy of existence and growth. In order to carry out this purpose of study, above all after has been reviewed Quality Management by considering the characteristics of construction companies, TQM component and business performance, the study has been made a close inquiry in causal relationship between TQM component(leadership, participation, education-training) and business performance(safety) in construction industry. The result of the study can be summarized as follows : First, a test was conducted to whether TQM component(participation) has a significantly positive effect on business performance(safety). Second, it was found that there was a positive casual relationship between each of the TQM factors and business performance(safety). TQM(Total Quality Management) factors had great influences on the business performance of construction companies. So construction companies needed to make continuous efforts to enhance the business performance through TQM approach.

The objective of this study is to improve safe execution of the management plan in Construction Technology Promotion Act. This research addresses the issue how to prevent the collapse of facilities under construction and after completion, improve the examination system, and execute Improvement of Safety Management Plan. To achieve this goal, research providing insights into understanding the ways in which creating and presenting safety checks and deploying safety training measures effectively is imperative.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as foundation, erection, structure, equipment finish and etc based on accident examples and investigation on actual condition in building. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.

Safety education should not only prevent workers from industrial accidents but also contribute to improve the productivity of manufacturing plants or construction sites. In practice this do not happen because workers do not realize the importance of safety education. This study aims to suggest a methodology to improve safety education of construction sites by surveying conditions of safety education and the safety consciousness of workers and engineers. The results showed that most education except regular educations were nominally carried out. Lectures and audio-visual education were mainly used as educational methods. After trainees attended the education session they completed a written survey, the most dissatisfied factor about safety education was education circumstances, of which rate was around 36%. The proportion of construction engineers who thought that safety management was contributable to cost reduction was 35%, to construction period 20%, and to quality enhancement 48%. Based on these results, this research pointed out the need to review training manuals, the development of educational programs, improvement of educational facilities to improve safety education of construction sites, and finally to discussed these issues.

According to the 2017 Industrial Accident Analysis by Age, 71.8 % of construction disaster victims and 74.9 % of the deaths were workers aged 50 years or older, highlighting the seriousness of industrial accidents among aged construction workers. In this study, 303 construction workers aged 50 or older and 178 safety managers were surveyed on ways to improve the basic occupational safety and health education for senior workers in the construction industry. According to a comparison of the safety awareness for safety education by senior workers and safety managers, the safety manager showed a higher sense of safety for education than elderly workers. Regarding the remuneration education for those who had received basic occupational safety and health education in the construction industry, 69.9 percent said that regular remuneration education was needed, and 69.9 percent of them said that basic occupational safety and health repair education in the construction industry was needed every three years after the completion of education. This study is intended to present improvement plans for repair education for those who have completed basic occupational safety and health training in the construction industry.

Aerial working platform is recently used broadly in heavy industry and construction field and also the utilization of it is growing. However, the raise of critical incident caused by unskilled operator is increasing gradually. To reduce and prevent such incident, the training for operating is essential. It's not easy to cover the requirements for the training with real platform because of the high price of it, safety and weather condition. This paper proposes a simulator for the training based on virtual reality to give the training safely regardless to the weather condition and the simulator is deliverable in lower price than real one. The simulator proposed in this paper is available to be set according to the level of trainee managing the assessment level and be also applied for the design of general heavy equipment training simulator based.
