A Total of 311 Ewha Graduates Pass the 2021 Public Teacher Employment Exam
A total of 311 Ewha graduates passed the final stage of the public teacher employment examination for the 2021 school year. Students who obtained a teacher’s certificate after completing courses at the College of Education, the Graduate School of Education, and the Teacher Training Program at Ewha were finally selected as eligible candidates for appointment as teachers at public schools through the first round of exams on pedagogy and major curriculums, and the second-round evaluation including in-depth interviews to determine teaching aptitude, preparation of teaching and learning guidance plans, and class demonstrations. Producing 270 successful candidates in 2019, 300 in 2020, and 311 in 2021, Ewha has successfully maintained its status as a comprehensive teacher training institution that offers majors in early childhood, primary and secondary school education, special education, and curriculum-based education for core subjects. Including the top and second-place candidates in multiple regions, Ewha produced a total of 311 successful candidates consisting of 27 for kindergarten, 43 for elementary school, 214 for secondary school, and for non-curricular positions in school health (2), librarian (2), nutrition (1), and professional counseling (22). In particular, in Seoul, Ewha graduates achieved the highest and second highest scores in early childhood special education, as well as the highest score in elementary special education and in fine arts education. Ewha graduates also took the position of top-scoring candidates in music education in Ulsan and Chinese education in Jeollabuk-do. These achievements prove Ewha’s excellent capabilities in training aspiring teachers. Ewha graduates achieved meaningful results and showed outstanding competence under difficult circumstances, having taken the first- and second-round exams during the COVID-19 pandemic. Meanwhile, the College of Education is dedicating its efforts towards supporting students to prepare the public teacher employment exam by operating a dedicated study room for exam preparations; offering special lectures by current school teachers and external experts; providing feedback on class demonstrations and performing in-depth mock interviews in preparation for the second-round exam; and supporting lectures and the purchase of teaching materials.

The Research Group of Professor Youngmin You Has Discovered a Model Capable of Predicting the Operational Lifetime of Organic Light-Emitting Devices A research team led by Professor Youngmin You of the Department of Chemical Engineering and Materials Science has established a model that can predict the lifespan of Organic Light-Emitting Devices (OLEDs) for the first time. Conducted by Yu Kyung Moon (first author), a graduate of the Combined Bachelor's-Master's Program of the Department of Chemical Engineering and Materials Science, the results of the study was compiled into a paper and published in Advanced Materials, a world-renowned scientific journal on materials science within the top 1.014% of JCR in chemistry and physics, on February 15 (Monday), 2021. The group has been focusing on the interactions between dopants and host materials, which are the key components of the light-emitting layers of OLEDs, in order to elucidate their influences on the operational stability of devices. The operational lifetime of OLEDs depends critically on the intrinsic stability of the materials. The group initiated research projects to uncover the chemical mechanisms that cause the deterioration of materials. Earlier studies published in Nature Communications in 2018 were on the blue-phosphorescent light-emitting layers, which receive huge academic attention. This time, the research group identified the entire processes of decomposition of thermally activated delayed fluorescence (TADF) dopants and host materials, including the formation of charge-separated species. Based on direct spectroscopic evidence, the group established a numerical model that can predict the operational lifetime of OLEDs. This model can be utilized to choose the best materials for the enhanced longevity of OLEDs. Professor You said, “It was difficult to know how long a display will be operated. But, our model can predict the operational lifetime of OLEDs, given the materials,” further voicing his expectations by adding “This study will provide an important steppingstone for improving the operational stability of OLEDs and significantly enhance the design of stable organic electronic materials.”
