Investigation on Occupational Health and Safety Education of College Students under the Overall National Safety Concept

To explore an effective approach to college students' occupational health and safety (OHS) education based on the premise of overall national safety (ONS), this study, through empirical investigation, first uses a structural equation model (SEM) to build and verify the OHS factor model, and then uses CHAID decision tree to conduct an in-depth analysis of the impact relations between the four types of factors. The research results show that the OHS factor model constructed in this study is reliable, and the ONS factors directly and positively affect the theoretical learning approach (TLA) factors, while the TLA factors directly and positively affect the simulation approach (SA) factors, and SA factors directly and positively affect the field practice approach (FPA) factors. The research results also show that the three types of OHS factors can be divided into four levels of ABCD, of which Level A is the key control factor, Level B is the secondary control factor, Level C is the general control factor, and Level D is the negligible factor. This research model and decision-making method not only clarifies the influence path of the three types of factors of ONS and OHS but also explores the sub-factor categories of hierarchical control, thus providing an effective guide for college students' OHS education.为探索基于总体国家安全观（overall national safety, ONS）前提的大学生职业健康安全（occupational health and safety, OHS）教育有效路径，本研究通过实证调研，首先采用结构方程模型（structural equation model, SEM）构建并验证了OHS因子模型，随后借助卡方自动交互检测（CHAID）决策树对四类因子间的影响关系展开深入剖析。研究结果表明，本研究构建的OHS因子模型具备可靠性；总体国家安全观因子对理论学习路径（theoretical learning approach, TLA）因子具有直接正向影响，而TLA因子对模拟学习路径（simulation approach, SA）因子具有直接正向影响，SA因子又对现场实践路径（field practice approach, FPA）因子具有直接正向影响。此外，研究还发现三类OHS因子可划分为ABCD四个层级，其中A级为关键管控因子，B级为次要管控因子，C级为一般管控因子，D级为可忽略因子。本研究的模型构建与决策方法不仅厘清了总体国家安全观与职业健康安全三类因子的影响路径，还探索了层级管控的子因子类别，可为大学生职业健康安全教育提供切实可行的指导。
