project, the effort to determine the cause of the accident is usually based on a relationship, a single equation Thus the recognition can not be the cause of the overall composition accidents In this study, a structural model represents the equation, the relationship between the variables involved mutual progress To build a model showing the influence of the group cause accidents and 350 questionnaires were examined (direct and Google Docs) to collect and analyze data according to the SEM analysis model The descriptive statistics are allowed to use the analysis of the survey results The causes of accidents are ranked according to the degree of influence of each cause more accidents The EFA and SEM further analysis, was used to analyze the impact and accident cause groups Since then, a theoretical model to show the impact as well as the relationship between the groups proposed cause accidents Results SEM model analysis also showed some differences compared with the theoretical model proposed initially From the analysis results, a model showing the impact of occupational accidents cause group is set to see the correlation relationships, influence relations of cause groups in a model For solutions to improve Health and Safety in the model, 20 survey questionnaires were sent to 15 experts to rank the seriousness of solutions effectively GVHD: PGS L TÓM T T n
