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.”

Research Team of Professor Na Jong-geol at the Department of Chemical Engineering and Materials Science Publishes a Paper in Applied Energy A joint research team at Ewha developed a solvent identification method to reduce greenhouse gas emissions easily and efficiently by applying deep learning technologies and chemical process simulations. Incorporating the findings of this study, a paper titled “Learning the properties of a water-lean amine solvent from carbon capture pilot experiments” was published in Applied Energy (SCIE), an academic journal within the top 3.85% of JCR in the engineering and chemical fields, on February 1 (Monday), 2021. Professor Na Jong-geol and his joint research team from the Department of Chemical Engineering and Materials Science at ELTEC College of Engineering developed a methodology to estimate the properties of a solvent that can efficiently absorb CO2, integrating deep learning technologies and chemical simulations to minimize the need for experiments. The Ewha research team developed a new water-lean amine solvent that can capture a large amount of CO2 using a lower amount of energy compared with existing solvents. In order to ensure the proper application of this newly developed solvent, it is necessary to develop an optimized process that is aligned with the thermodynamic and kinetic characteristics of the solvent. The research team applied a deep learning-based hybrid Bayesian inference technique to the pilot-scale tests, through which the team made it easier to infer the properties of a solvent using solely the pilot process with many uncertainties, and enabled the simultaneous implementation of a large-scale process optimization and analyses of the physiochemical properties of a solvent. This advancement is expected to reduce costs for processing greenhouse gases and lead to a large-scale reduction in CO2 emissions. This study was jointly conducted by Professor Na Jong-geol (co-first author) at Ewha, senior researcher Lee Ung (corresponding author) at the Korea Institute of Science and Technology, and Dr. Kim Jeong-nam (co-first author), with the support of the “Carbon to X technology development project for the production of value-added chemicals” under the National Research Foundation of Korea (NRF). Professor Na remarked, “The key of this study was to develop a methodology to simultaneously carry out the properties analysis and optimization processes, which were previously conducted in sequence,” and added, “This represents a successful case of a convergence study combining AI and domain knowledge to apply deep learning technology onto chemical process technology as a step toward achieving zero carbon emissions.” In particular, he emphasized, “This study is expected to greatly improve the speed of product development through highly advanced design techniques including AI-based solvents, materials, and catalysts,” voicing his aspirations to lead the field in the future.

Ewha Holds Groundbreaking Ceremony for Remodeling and Partial Reconstruction of Hak-gwan

Transforming the home of Ewha’s College of Humanities and large-scale liberal arts courses into a cutting-edge modernized space after 57 years since its completion Building a suitable educational environment for the Fourth Industrial Revolution, incorporating high-tech lecture rooms, multipurpose halls, and lounges At 2:00 PM on Monday, January 25, Ewha Womans University held a groundbreaking ceremony at the square in front of Hak-gwan for the remodeling and partial reconstruction of the Hak-gwan building. Hak-gwan was originally constructed to expand the educational space for students as Ewha rapidly grew into one of Korea’s top universities while going through the tumultuous years following the country’s liberation from Japan and the Korean War. Its construction began in 1960 and was completed in 1964. With a total floor space of 4,355 pyeong, or 14,400m², and one basement and seven ground levels, Hak-gwan was the largest building on the campus at the time, and mainly used for department offices and research institutes of the College of Humanities. In celebration of the 57th anniversary of the completion of Hak-gwan, Ewha is planning to transform the building into a future-oriented educational space balancing tradition and cutting-edge modernity through its remodeling and partial reconstruction. At the ceremony, President Kim Heisook remarked, “Although Hak-gwan was mainly used by students from the College of the Humanities, the building was a familiar sight for many other Ewha students and a place of fond memories since they attended large-scale lectures and liberal art classes in Hak-gwan.” She added, “Through this remodeling and partial reconstruction, we plan to preserve the symbolic significance of this longstanding monument to Ewha’s tradition, while transforming it into an educational environment suitable for the Fourth Industrial Revolution. I ask for your generous support until the completion of the building.” The remodeling and partial reconstruction of the building is divided into a remodeling area (10,795.44m²) and a reconstruction area (6,838.24m²), and scheduled to be completed by July 2022. To this end, the Office of University Relations and Development has launched a campaign titled “Hak-gwan Remodeling and Reconstruction Fundraising Campaign”, and is gathering support from alumnae who have fond memories of classes at Hak-gwan, as well as the College of Humanities Alumnae Association. For donations of more than three million won, the donor’s name will be inscribed on the donor recognition board in addition to other courtesies such as the installation of donor plaques or the naming of spaces after donors’ names, depending on the donated amount.

Ewha Produces Ten Successful Candidates for the 57th Patent Bar Examination

Ewha produced total of ten successful candidates in the 57th Patent Bar Examination. Patent lawyers, a profession that represents clients in obtaining patents for industrial property rights or litigations, are currently rising to the spotlight as the importance of intellectual property is increasing with the advent of the Fourth Industrial Revolution. Among 1,157 applicants in total, 210 applicants (18.15%) passed the examination according to the announcement of successful candidates for the 57th Patent Bar Examination released by the Human Resources Development Service of Korea on Wednesday, January 20. The number of successful applicants increased by seven compared to that of last year (203, 17.50%), but the number of successful female applicants was 62, which is a continuous decrease from the number of 55th (78, 37.7%) and 56th (74, 36.5%). Despite the overall decrease in the number of successful female applicants, Ewha once again demonstrated its excellence by producing 16% of all successful female applicants. The rate of successful applicants among enrolled students increased as five Ewha students passed the examination while currently enrolled at Ewha, and seven successful applicants participated a patent bar exam prep club provided by the school. Ewha has been operating a patent bar exam prep club since 2005 and newly established special classes for students who are preparing for higher civil service exams (technical posts) and patent bar exams since April 2010 in the Ewha-SK Telecom Center, striving to improve students’ competitiveness by providing a dedicated study room, books, and classes at private academies.

Research Team Led by Prof. Chun Lays the Cornerstone for the Development of a Measurement Scale for Youth Cyberbullying

A research team led by Professor Chun JongSerl from the Department of Social Welfare has drawn attention by presenting a systematic review of tools to measure cyberbullying in 17 countries around the world, identifying problems with existing tools and developing a foothold for an international standard to ensure the accuracy of such measurements. The research findings were published in the global academic journal Computers in Human Behavior (impact factor = 5.003, top 5% in Psychology and Experimental categories) under the title “An international systematic review of cyberbullying measurements.” At a time when the importance of online interactions is rising rapidly due to COVID-19, the existing problem of school violence is evolving into a new form of cyberbullying that transcends time and place, owing to the increased use of smartphones and social media. However, there is no standardized scale for the objective measurement of this problem. As such, the research findings from Professor Chun’s team are considered a significant achievement in a context where the incidence rate of cyberbullying has not been accurately identified. The research team analyzed 64 international studies on cyberbullying severity scales in accordance with PRISMA guidelines, using the following categories: general characteristics, definition of cyberbullying, study sample characteristics, sample size, format of scale, time frame, survey type, criteria extraction method, reliability, and validity. The results of the study showed that 71.9 percent of the examined papers provided concepts and definitions of cyberbullying but failed to present a standardized definition, as the term is used interchangeably with similar concepts, such as online violence and cyber violence. In addition, existing cyberbullying scales were developed in Western countries while only five papers cover cases in Asia, raising the need to develop measurement tools that reflect the socio-cultural characteristics of Asian countries. Furthermore, there were no measurement scales that reflect gender characteristics despite gender differences in the number of cyberbullying victims, and about 30 percent of the papers did not clearly measure the time of occurrence for cases of cyberbullying, indicating insufficient accuracy. Particularly, existing measurement tools showed low degrees of reliability and validity, with only 23 percent of studies developing measurement tools following the scale development guidelines and procedures and only half of them verifying the reliability and validity of the measurement tools. This study was conducted with the support of the National Research Foundation of Korea, with Professor Chun JongSerl as the lead and corresponding author and Professor Lee Jungup at the National University of Singapore and Ewha Ph.D. students, Kim Jinyung and Lee Serim as co-authors.

Research Team Led by Prof. Lee Sang-gi Publishes Paper in Chemical Reviews

The research team led by Professor Lee Sang-gi from the Department of Chemistry & Nanoscience in the Ewha College of Natural Sciences published a paper in the top-rated international science journal Chemical Reviews (Impact factor=52.76) under the title of “Synergistic Dual Transition Metal Catalysis” on Wednesday, December 23. Catalysis, the process of using small amounts of catalysts to synthesize large amounts of products, is the most atom economic reaction. As such, different kinds of catalytic reactions have been developed over the past few decades, especially those using transition metal catalysts, which play a vital role in the synthesis of natural products, medicines and functional materials. In particular, recent years have seen the rapid growth of research in the field of "synergistic dual catalysis," which selectively activates two types of substrates using two different types of catalysts. As the selection of catalysts is critical for the success of synergistic dual catalysis, many researchers have been studying reactions that take place through dual catalysis using two organic catalysts or the combination of an organic catalyst and a transition metal catalyst, which ensures very little or no redox reaction between catalysts. Professor Lee became the first in Korea to research synergistic dual catalysis in 2014 with the support of the Samsung Future Technology Incubation Program, and secured research funding from various projects such as a support program for mid-career researchers under the National Research Foundation of Korea, eventually publishing his research findings and leading the field of organic synthesis and catalysis. The paper presented the findings published up to June 2020 by research teams at Ewha as well as other global researchers on synergistic dual catalysis between two transition metal catalysts. It is expected that the paper will contribute to the understanding of synergistic dual catalysis using transition metal catalysts and to building the foundation for related research. The paper was published with support from the BK21 PLUS Project under the names of Professor Lee Sang-gi as a corresponding author; post-doctoral researcher Kim U-bin as the first author; Dr. Jung Da-jung and Dr. Jeon Hyun-ji who are graduates of the Department of Chemistry & Nanoscience; and post-doctoral researcher Dr. Kris Rathwell.
