Selection as a new author for excellent research paper in accounting field by Korean Accounting Association Reveal of the importance of financial statement ‘other’ accounts was revealed for the first time [September 26, 2023] Dr. WOO Hye-jin (36, research faculty at YU Business Research Institute) from Department of Accounting and Taxation of YU (President CHOI Oe-chool) won 2023 Accounting Dissertation Award of Korean Accounting Association. <From the left, Dr. WOO Hye-jin and Professor HONG Young-eun> The Korean Accounting Association is the most authoritative academic organization in the accounting field. It was established in 1973 for the purpose of developing Korean accounting research and education and sound research activities in accounting. It selects excellent theses and gives thesis awards every year to promote accounting research by new researchers. Dr. WOO Hye-jin’s thesis <Why should information users be interested in 'other' account subjects after the introduction of K-IFRS?> is the first study to show that the ambiguity and abstractness of the classification standards contained in “other” account subjects is used strategically by managers as management's discretion in presenting financial statements has expanded, because Korea International Financial Reporting Standards (hereinafter referred to as K-IFRS) established by Korea Accounting Standards Board in 2007 to meet International Financial Reporting Standards (IFRS) have been mandatory for all listed companies since 2011. Currently, financial statement account items that are displayed in different ways for each company are provided in a uniform manner in the existing database system.In this study, the reliability and accuracy of the data was increased by collecting “other” account subject data used differently by individual companies using web crawling rather than using account subject classification in a standardized database system.In addition, after the introduction of K-IFRS, which is an important standard for calculating accounting information, it is significant to clarify that information users should be careful when making decisions using accounting information that includes “other” items. Dr. WOO Hye-jin said, “I would like to thank my advisor and the professors of the Department of Accounting and Taxation who taught me a lot during the research process. In connection with this doctoral thesis, I was selected for the National Research Foundation of Korea’s Humanities and Social Sciences Academic Research Professor Support Project and am currently working on “Other Account Subjects.” We will also faithfully pursue research related to ‘information usefulness.” Professor HONG Young-eun of YU Department of Accounting and Taxation, the advisor, said, “After the introduction of K-IFRS, the research results that contributed to increasing the reliability and accuracy of accounting information seems to have been recognized by the academic community. We are making more efforts to produce excellent talents in the field of accounting.”

Professor KIM Chang-seop’s research team developed “ultra-film silica nanoparticles to be used as a carbon reduction biocatalyst” Increased utility of enzyme-based green chemistry technologies through improved mass transfer and stability Published in the latest issue of Chemical Engineering Journal, an internationally renowned journal in the field of chemical engineering [September 14, 2023] '<From the left, YU Professor KIM Chang-seop, student LEE Ae-seol, and Dr. HEO Hye-ryeong> The research team of Professor KIM Chang-seop (40) and Dr. Heo Hye-ryeong (36) of YU Department of Chemistry of YU (President CHOI Oe-chool) developed micelle-based ultrafilm silica nanoparticles to be used as a carbon reduction biocatalyst. Enzymes have advantages such as high activity and selectivity, few by-products, and environmentally friendly conditions, but their use in industry is limited due to their low stability. However, Carbonic anhydrase (CA)*1 is a biocatalyst that hydrates carbon dioxide and is a protein that is receiving great attention in environmental industries as it can be used in carbon capture and sequestration (CCS) technology. Recently, Professor KIM's research team developed a biomimetic enzyme encapsulation technology to increase the stability of carbonic anhydrase enzyme and increase its industrial use as a carbon reduction biocatalyst.The research team said, “With the technology developed this time, we can utilize the biosilicification reaction of diatoms to imitate the environment and structure within diatoms*2 and at the same time protect enzymes from external stress environments. Diatom-derived silica-forming peptides and carbonic anhydride Nanoparticles with a polar silica layer were developed using micelle*3 with enzymes immobilized on the surface as a template. We succeeded in increase of enzyme stability with the silica layer of the polar membrane and succeeded in minimization of mass transfer limitations.” <Schematic diagram of a polar membrane mesoporous silica nanoparticle biocatalyst with high mass transfer efficiency and stability> Professor KIM Chang-seop, who led the research team, said, “The micelle-based ultrafilm silica nanoparticle biocatalyst developed this time showed improved stability even under carbon capture and removal technology (CCS) reaction conditions. This shows the possibility that the biocatalyst developed through this can be used in an actual industrial environment. The utilization of enzyme-based technology can be increased, and there are no restrictions on applicable enzymes or biomolecules, so we plan to conduct research to apply it to biomedical engineering applications.” LEE Ae-seol (30, Ph.D. completed) from Department of Biochemistry at YU Graduate School participated as the first author in this study and the research paper was published in the renowned international journal <Chemical Engineering Journal> in the chemical engineering field (impact factor (IF) 15.1, top tier). (within 5%) was pre-released online in the latest issue (dated October 1, 2023).This research was conducted with support from the New Researcher Support Project, the Sejong Science Fellowship Project and from the Project of Medical Research Center (MRC) of Leading Research Center supported by the Ministry of Information & Communication and National Research Foundation of Korea.

Significant reduction of process time and energy consumption with use of high-output light energy Expectation of application to manufacture of flexible electronic components and semiconductors Recognition of academic value through publication in an international renowned academic journal (Advanced Materials) in the field of new materials studies [September 22, 2023] A joint research team led by Professor RYU Jeong-ho of Department of Materials Science and Engineering of YU (President CHOI Oe-chool) coated existing film-type ceramic materials on metal substrate and, instead of using high-temperature heat treatment, irradiated strong light similar to that used in a camera flash for 1/1000th of a second to produce ceramic material. As the result, high performance of ceramic materials were obtained, attracting attention from academia and industry. More than 70% of electronic device components such as smartphones, tablets, computers, and TVs are made of ceramic materials.Recently, due to miniaturization and high performance of electronic devices, electronic components using ceramic materials are also being used by forming them on a substrate in the form of a thin film. However, in general, in order to properly realize the characteristics of ceramic materials, they are manufactured (sintered) with heat treatment of raw materials at high temperature of over 1,000 degree and the types of substrates to be used as base materials for the film were limited. Professor RYU's research team succeeded in development of technology to heat-treat ceramic films without any influence to heat-instable metallic substrates by momentarily exposing the ceramic film to high-output light energy using xenon gas discharge.By developing flexible electronic component manufacturing technology that was impossible with existing high-temperature heat treatment methods, the characteristics of the device were significantly improved. Through the development of this technology, which enables large-area heat treatment with instantaneous light in a simple structure, it is possible to overcome the disadvantages of processes that took dozens of hours using existing expensive laser equipment or using traditional electric furnaces and it is expected that the potential for commercial application will be high. <Overview of heat treatment technology for flexible ceramic thin film materials using high-energy light> Professor RYU said, “We have developed a photothermal treatment technology that dramatically reduces the time and energy consumption required in the high-temperature heat treatment process of existing electric furnaces and overcomes the limitations of the substrates that make up electronic components. It is expected to be applicable not only to manufacturing parts with optical, electrical, and magnetic properties of ceramic materials on polymer substrates or flexible metal substrates, which are essential for the development of flexible devices that can be attached to the human body, which have recently attracted attention, but also to semiconductor heat treatment processes.
