Human factors are important causes of hazardous chemical storage accidents, and clarifying the relationship between human factors can help to identify the logical chain between unsafe behaviors and influential factors in accidents. Therefore, the human factor relationship of hazardous chemical storage accidents was studied in this paper. First, the human factors analysis and classification system (HFACS), which originated from accident analysis in the aviation field, was introduced. Since some items were designed for aviation accident analysis, such as the item “Crew Resource Management”, it is not fully applicable to the analysis of hazardous chemical storage accidents. Therefore, this article introduced some modifications and changes to make the HFACS model suitable for the analysis of hazardous chemical storage accidents. Based on the improved HFACS model, 42 hazardous chemicals storage accidents were analyzed, and the causes were classified. After analysis, we found that under the HFACS framework, the most frequent cause of accidents is resource management, followed by violations and inadequate supervision, and finally the organizational process and technological environment. Finally, according to the statistical results for the various causes of accidents obtained from the improved HFACS analysis, the chi-square test and odds ratio analysis were used to further explore the relevance of human factors in hazardous chemical storage accidents. The 16 groups of significant causal relationships among the four levels of factors include resource management and inadequate supervision, planned inappropriate operations and technological environment, inadequate supervision and physical/mental limitations, and technological environment and skill-based errors, among others.
To improve the effectiveness of the international course for safety engineering at China University of Mining & Technology (Beijing) (CUMTB), we explored sustainable development methods, co-occurrence analysis, statistical analysis, and questionnaire survey methods in a discussion of the international course’s current state and problems. First, the international course’s research topics and trends were analyzed. Second, other Chinese universities with international courses in safety engineering were counted. Finally, the international courses in safety engineering at CUMTB were analyzed from three aspects: teachers, teaching content, and course effect. The results show that there is a developing trend in international course research focusing on specific disciplines. For the safety engineering international course at CUMTB, foreign university teachers are the first choice for course instruction; however, the language barrier is a primary problem. In terms of teaching content, students are more interested in their intended employment fields and lack an understanding of various research fields. The course meets the students’ expectations but can still be improved. According to the results, we conclude that bilingual teaching by ethnic Chinese university teachers leads to more efficient knowledge acquisition. A guidance course and a survey of students’ employment intentions should be added before the course. Through these measures, the international course’s effectiveness and quality can be improved to better realize sustainable development.
An inkjet printed 31‐inch UHD AMOLED display has been successfully developed in this report. Special designed small size pixels, high thermal stable top‐gate self‐aligned a‐IGZO TFTs, multiple‐planarization method and cost‐efficient inkjet printing process make the display very attractive. For the AMOLED display, HIL, HTL and EML (Red, Green, Blue) layers were printed in multiple‐planarized small pixels by precisely controlling the ink droplets. And ETL, cathode were prepared on the whole panel by VTE with just common masks instead of complicated and expensive FMMs, which provides a low‐cost fabrication approach for the following emerging inkjet printing display era. The light‐on image of the developed display indicates that good full color and display uniformity has been successfully realized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
