Purpose: This study investigated the effects of reeducation of nursing process on nurses' expertise, critical thinking disposition, and clinical decision making. Methods: Data were collected from March to June, 2007. The subjects were 47 Academic Credit Bank System Student Nurses. They were taught 'nursing process' during 1 semester(15weeks). 47 nurses were divided into three groups according to clinical experience(under 3 years, 3 to under 5 years, 5 years or more). After 15 weeks, the effects of education were compared using a paired t-test between pre-test and post-test. Results: There was a significant difference in the 3 to under 5 years experienced nurses's expertise(t=-3.659, p=.004) between the pre-test and post-test. There was a significant difference in the 5 years or more experienced nurses's expertise(t=-5.781, p<.001) and critical thinking disposition(t=-3.345, p=.003) between the pre-test and post-test. There were no significant differences in clinical decision making(accuracy, proficiency, and confidence) of 3 groups. Conclusion: Reeducation of nursing process is a valuable teaching and an evaluation strategy for 5 years or more experienced nurses to improve expertise and critical thinking disposition. We need to develop continuing education program for improving nurses' clinical decision making.

Librarian certification in Korea is issued by the LIS Departments, the Academy of Librarianship, and the Academic Credit Bank system; however, it has been pointed out that there is a limit to how much these nurture high quality librarians, because the education quality and contents varies from education institutions and there is no verification method for certification issued by educational programs. Therefore, this study investigated certification systems of academic or training programs that are conducted at home and abroad, analyzed how the certification systems are oriented, what the purpose and criteria of the certification systems are, and what the content of assessment is. As a result of this investigation, several areas needing change were identified which if adopted can improve the system. These included making amendments to the library laws related to the certification system, substantially revising the relevant enforcement ordinance, making changes to the selection of the Certification authority, establishing certification standards and procedures, developing contents related to document examination and due diligence audits, rating the effects of the certification system, and setting standards. Improving the Librarian Certification System has been discussed over the past 20 years and should not be delayed any longer because of the university structural reform of the current government, the rapid rise of the qualified librarians, decreasing employment due to the human resources supply and demand imbalances, all of which has resulted in a survival crisis of four-year Department of Library and Information Science.

Coinciding with the advent of COVID-19, online education is on the rise both domestically and globally, and has become an absolutely necessary and irreplaceable form of education. It is a very curious question what the perception of people about the suddenly growing form of education is, and how it has changed. This study investigated changes in consumers' perception of online education using big data. To this end, we divided the time into four stages: before COVID-19 (November to December 2019), after the triggering of COVID-19 (January to February 2020), right after the online classes started (March to April 2020), after experiencing some online education (May to June 2020). Then we conducted text mining, namely, keyword frequency analysis, network analysis, word cloud analysis, and sentiment analysis were performed. The implications derived as a result of the analysis can help education policy makers and educators working in the field to improve online education quality and establish its future directions.
