Purpose: This study is descriptive survey research on the analysis of nurses' perception of the 4th industrial revolution and the importance and performance of future core nursing competencies in a tertiary hospital located in Seoul. Methods: Data were collected from 149 nurses with more than a year of work experience and analyzed using descriptive statistics, t-test, one-way ANOVA, and Importance Performance Analysis(IPA) with the IBM SPSS/WIN 25.0 program. Results: The nurses' perception of the 4th industrial revolution was 3.23±0.71 out of 5 points. The importance of future core nursing competencies was 4.31±0.48, and the performance of it was 3.47±0.54. The analysis results of IPA showed that A (area of continuous maintenance) included critical thinking, problem-solving skills, teamwork and collaboration, evidence-based practice, communication, quality improvement and safety, professionalism, self-regulation and self-management, and personal literacy. The specific competencies were not included in B (area of priority improvement). Creativity, informatics, healthcare policy, leadership, research ability, and continuing education were included in C (area of progressive improvement). Knowledge and patient-centered care, ability to manage resources as well as professional, legal, and ethical responsibility were included in D (area of overinvestment). Conclusion: The nurses seemed not to be fully prepared for the 4th industrial revolution. However, they were well aware of the importance of the future core nursing competencies. Therefore, if nurses increase the performance of core competencies in order of priority according to the IPA results, they will be able to independently lead the changing nursing field.

Objectives: After the MSDS submission and non-disclosure review system was introduced in January 2021, there were compliance difficulties in the field. Accordingly, for the establishment of the MSDS system, the government intends to investigate what has been improved and what urgently needs to be improved in the future, and to suggest detailed improvement plans. Methods: The background and problems of urgent difficulties in the field handling chemicals were investigated, and realistic improvement plans were derived through review of other laws related to the MSDS system and overseas cases. Results: In order to guarantee the safety of the public while at the same time promoting corporate R&D, it is necessary to alleviate the non-disclosure screening system for chemical substances for R&D, and to improve the irrationality of failing to implement the non-disclosure screening system due to information on unclassified substances being circulated. For this reason, it seems necessary to ease the requirement to submit all ingredients. In addition, it is necessary to strengthen punishment to raise awareness so that health problems do not occur due to the harmfulness and danger of hidden substances among workers who handle chemical substances and downstream users due to false descriptions in MSDS. Conclusions: All members of our society, including chemical manufacturers/importers and handling companies, academia, civil society, and the government, each subject of chemicals, should take an interest in the entire process from production to disposal of chemicals and work together to prevent harm to the public.
