건설현장 내 산업재해 감소를 위한 안전 사이니지 시스템 디자인 연구-다문화 근로자 작업 환경을 고려하여-

The purpose of this study is to study the development direction of digital safety marking system in order to identify limitations of existing safety signs and changing working environment and to reduce industrial accidents including multicultural workers. First, through the literature survey, we found the status of industrial accidents in all industries and the characteristics of industrial accidents in construction industry. Second, we investigated the actual status of safety signs in domestic construction sites and identified the limitations of the current safety sign system. Third, I investigated the actual situation of multicultural foreign workers in the construction industry and found problems related to them. Fourth, we conducted in - depth interviews with workers and managers in the construction site and derived the elements necessary for the design of the safety mark system based on the contents. Finally, the safety sign system design using digital signage is presented by referring to the above - mentioned factors and overseas cases. According to the literature survey, the industrial accident rate of the construction industry increases as the year progresses, and the proportion of foreign workers and the industrial accident rate also increase every year. Currently, there are many kinds of safety marking systems on construction sites. They are not unified. Especially, according to individual recognition methods such as language, culture, cognition, and value of multicultural workers, understanding of safety markings is different, It was found that the efficiency was low. In order to investigate the requirements for developing a new safety label system, we visited three construction sites and conducted in-depth interviews with field managers, domestic and foreign workers on the problems of the current safety management system. The results of the interviews were analyzed and the elements for developing the safety management system were divided into three aspects: system operation factor, utilization factor, and multicultural factor. Based on the results, we have presented an example of the configuration and graphic application of the safety sign system that utilizes digital signage considering multicultural workers. In future, it is necessary to study detailed factors such as individual culture background, language, cognitive acceptance process of domestic and multicultural workers, and further study on effective cognitive element discovery and information delivery method in terms of user experience is needed.
