Chí Minh ch mơ hình ABSTRACT In recent years, Occupational Safety and Health in the construction field continues to be disturbing problem In Vietnam 2013, the statistic reports state that 28.6% of the accidents occurred related to the construction field Labor accidents causing loss of life, physical, performance, schedule Although in the construction field in Vietnam, companies has caried out to improve safety but effecttive Workers and employers who still not have a full awareness of the importance of ensuring the health and safety work Thereby improving safety culture in an organization is having particular importance in improving safety Accordingly, the objective of the study was to identify effective factors to the safety culture of the organization, developing a model of interaction between factors in the safety culture of the organization, finally propose model of theory model of safety culture in the organization These thesis is mainly based on a master thesis A System Dynamics Approach to Construction Safety Culture by Thandawee Chinda which is redone in real conditions in Vietnam By the combination of documents, other studies was carried out and consult experts, a framework for assessing the interaction of factors of the safety culture in organization was proposed, it included 32 elements contained in the six factors (six contructs): leadership, people, partnerships and resources, policy and strategy, processes and objectives EFA and SEM analysis was conducted to test the suitability of the elements In addition, It also determined the causal relationship between the contructs of safety culture Finally, a theoretical dynamic model (System Dynamics) is proposed as a Preliminary model of the safety culture in real conditions in Ho Chi Minh City Result of analysing SEM model said that leadership factor affect all of three factors such that People, Partnerships and Resources, and Policy and Strategy In addition, the indirect effects between these factors also were indicated in the model Tôi, , cá v I M CL C I THI 1.1 Lý ch TÀI tài 1.2 Câu h i nghiên c u 1.3 M c tiêu (m 1.4 u ng ph m vi nghiên c u ng nghiên c u 1.4.2 Ph m vi
