[Academics][Researcher of the Month] Customizing Breast Cancer Treatment through Big Data

In 2015, Professor Kong Gu (College of Medicine) was a pioneer in the field of breast cancer research and treatment, laying the foundation for web-based precision by mapping 560 breast cancer whole-genome sequences. Kong is now developing a screening system for breast cancer with multiomics and big data, paving the way for customization and personalized breast cancer treatment. Professor Kong Gu (College of Medicine) developed a target gene screening system for the diagnosis and treatment of breast cancer. Breast cancer is one of the most common types of cancer among women, causing death to 1 out of 38 women. The cancer is classified into three subtypes, which are Estrogen Receptor (ER) positive, HER2 positive, and triple-negative. The latter two – which make up fewer than 30 percent of all cases – usually have bad prognoses. Through this research project, Kong sought to find the target gene of malignant tumors through multiomics. Multiomics is a new approach where the data sets of different omic groups, such as the genome, proteome, and transcriptome, are combined during analysis. By unpacking 41 data sets from METABRIC, TCGA, and GEO, Kong made a target gene screening system that allows researchers to customize the treatment of potential patients. “It is a platform to provide the individualized surgical target with data visualization,” explained the professor. Data visualization, survival analysis, and target gene screening are three main points in this research. (Photo courtesy of Kong) Kong, who is one of the first Korean scholars to introduce the polymerase chain reaction (PCR) test, said it was a challenge for him to conduct this research. “Most of what I have studied as a researcher was on biotechnology(BT),” said Kong. The latest research, however, involved informational technology (IT). He said a lot of help was given to him from Kim Hyung Yong, a Ph.D. candidate who majored in bioinformatics for his master’s degree. Kong tried to learn IT himself, as well as to pass his knowledge of breast cancer on to his doctoral student. “It was an opportunity to remind me that the path of learning is long and winding," recalled Kong. Kong said it was definitely a challenge to encounter informational technology (IT) in his research. Kong advised the members of Hanyang to be engrossed in their path. “Stay focused on your interests with constant effort,” advised the professor. “You will eventually become an expert in the field.” Oh Kyu-jin

[Academics][Excellent R&D] How to Ensure Structural Safety During Remodeling

Professor Choi Chang-sik (Department of Architectural Engineering) has developed the technology to ensure structural safety when vertically extending buildings. Unlike previous methods, Choi's method strengthens the existing wall structure without adding to or thickening of the walls; thus, it does not reduce the floor space. Out of all residential premises in South Korea, 55 percent are more than 30 years old (figure from 2018). When a building is decrepit, it can either be demolished and reconstructed or partly remodeled. Choi's research aims to deal with problems that arise while remodeling, especially when doing a vertical extension. Professor Choi-Chang-sik (Department of Architectural Engineering) is explaining the reason why shear walls are important when extending a building. To increase the number of floors of a building, many aspects must be considered. These include the vertical weight that will be put on the walls and pillars, horizontal weight which is related to wind and earthquakes, as well as the flexural strength. The taller the building, the more stress is put on the importance of the horizontal weight and flexural strength. The type of wall that is designed to support these two factors is called a shear wall. Choi's method of strengthening sheer walls differs from the previous adhesion-type method in that it does not thicken the walls or increase the number of walls. He first calculates the necessary thickness of the stiffener and cuts out the same size area from the existing wall structure. The stiffener is then applied onto the vacant area. This method gives the advantage that it will not reduce the actual floor space of the living area. Choi explained that the team has successfully finished the technology development as well as completed testing on real-scale structures. The only thing left is to test it on an actual building. "We are currently facing difficulties because there are not many complexes that are willing to try out the new technology. Furthermore, apartments in general do not prefer remodeling over reconstruction, so it is very hard to find an apartment to apply our method on," said Choi. “People feel vague anxiety about reusing an old structure as the base. However, remodeling involves as much technical verification as reconstruction. I hope people can trust the safety of our remodeling method." Hwang Hee-won

[Academics]Professor Lee Young-moon Creates an Application that Prevents Smartphones Shutting Down in Cold Weather

Professor Lee Young-moon's team of professors from the department of Robotics at Hanyang University created a technology that prevents smartphones from turning off in cold weather, reported Hanyang Univerisity on the 15th. Older smartphones turn off in cold weather more frequently causing extreme inconvenience to the users. The solution to this problem has become a big interest in the mobile industry. Professor Lee Young-moon Initially, the system in smartphones minimizes the usage of electricity at high temperatures while maximizing electricity usage at low temperatures to prevent heating issues. However, at low temperatures, the internal resistance of the battery increases rapidly. This, along with an increase in electricity usage, causes the battery supply to drop quickly. This results in the smartphone turning off. Professor Lee Young-moon's team from the department of Robotics created an application called Battery-Aware Power Management (BPM), together in collaboration with Professor Shin Kang-Gun of Michigan University in the United States, which solves this problem. The joint research team improved operational stability with a smartphone application by analyzing battery capacity and controlling the decrease in battery voltage in cold environments without the use of additional equipment. After various tests by the OEM, the joint research team found out that the battery availability increased by 38%, and the operating time improved by 30% at a temperature of minus 5 degrees Celcius. This research was supported by Hanyang University (Task name: Embedded System Battery and Power Management) and the American Science Foundation. The results of the study (Paper name: Causes and Fixes of Unexpected Phone Shutoffs) was published at ACM MobuSys 2020, the most prestigious academic conference in the field of mobile systems, and presented at on open online conference ( last month.

[Academics][Researcher of the Month] Reducing Fine Dust From GDI Engines

The increasing amount of fine dust is threatening modern people’s daily lives. In response to the problem, Professor Park Sung-wook (Division of Mechanical Engineering) has been studying ways to decrease the amount of fine dust in the air while maintaining the efficiency of automobile engines. In his recent research paper titled “Effects of spray behavior and wall impingement on particulate matter emissions in a direct injection spark ignition engine equipped with a high pressure injection system,” Park presented a solution to lowering the amount of fine dust emitted by Gasoline Direct Injection (GDI) engines of gasoline-powered cars. The research focuses on spray visualization, particle number (PN) measurement experiments, injection timing, and an engine load being varied to examine their effects on the way fuel sprays move when being injected inside a combustion chamber, hereinafter referred to as the spray behavior. The analysis was based on time-averaged spray images, spray variations between cycles, combustion, and PN emission characteristics. "The motivation behind this research was the prevalent misconception that diesel cars are the main source of fine dust, when in fact gasoline cars’ GDI engines emit just as substantial an amount of fine dust," said Park. Professor Park Sung-wook (Division of Mechanical Engineering) experimented in order to help automobiles emit less fine dust. (Photo courtesy of Park) What Park considered most important in the research was the PN emission characteristics. He endeavored to find new ways to decrease PN emission in the air instead of reducing the dust's total weight. “What matters the most in reducing fine dust is the size of each dust particle," explained Park. "The combined weight of the dispersed fine dust is secondary - for the size of the particle determines its harmfulness to the human body.” After 5 years’ cooperation with Hyundai Motor Company, Hyundai KEFICO, the Ministry of Environment, and the Ministry of Industry, Park and his team have been able to conclude that when fuel is injected at a high pressure, the flow in the combustion chamber is strengthened, and the atomization of the fuel spray is propelled in action in order to decrease fine dust in the air. “This has been a significant research project during which we have found ways to decrease the amount of fine dust emitted by existing hybrid automobiles and internal combustion automobiles, without having to accelerate the commercialization of electric cars, which would be difficult to do for several more years.” Park said five great students have earned their doctorate degrees through this experiment and thanked his pupils for constantly helping him in times of distress and uncertainty.

[Academics]Professor Ko Min-jae's Joint Research Team Has Developed the New Perovskite Quantum Dot Solar Battery

Hanyang University's Department of Chemical Engineering Professor Ko Min-jae's team announced on July 14 that together with DGIST Department of Energy Convergence Research Center's Professor Kim Young-hoon they have developed the New Perovskite Quantum Dot Solar Battery. This technology also holds light energy electroluminescence characteristics and is expected to contribute to the commercialization of optical technologies such as building-integrated solar energy generation, multi-functional photoelectric devices, and Li-Fi. Quantum dots have great light-absorbing capacities and are one of the key elements of next-generation solar batteries, which absorb light from large areas. The perovskite quantum dot solar battery has the ability to transfer light into electric energy and electricity into light, and is known to have the highest efficiency in the quantum dot solar battery field. In order to synthesize superior perovskite quantum dots, organic ligands, which have a long hydrocarbon chain, are used. Ligands adhere to small perovskite quantum dots of 10 nanometers (nm) on the surface and allow them to disperse in diverse nonpolar solvents. When these quantum dots are well-arranged on boards, quantum dot solar batteries are created. Here, as a long-chain ligand adheres to a quantum dot’s surface, it makes the charge transfer difficult between quantum dots, a process which degenerates solar battery functions and where transfering it to the ligand chain where hydrocarbon is required. The research team focused on the hydrophobicity (not easily combine with water molecules) of benzene group-based phenethylammonium (PEA) ligands. They then succeeded in applying this safely to the perovskite quantum dot's surface. Through this, they improved the efficiency of transforming solar energy into electric power to 14.1% and additionally tried to keep high photovoltaic efficiency stability of over 90% for 15 days in an environment with relative humidity of 20~25%, which is similar to external environments. Doctor Kim Young-hoon said that “we investigated and have discovered for the first time that by applying a ligand which holds both a short hydrocarbon chain and hydrophobicity, that both a quantum dot solar battery’s performance and safety can be improved at the same time,” and that “this will provide a new paradigm for developing and commercializing a next generation quantum solar battery”. In this research, Hanyang University's Department of Chemical Engineering's master’s and doctorate program student Kim Ji-gun and the DGIST Department of Energy Convergence Research Center's post-doc participated as the lead author and was published online in Nano Energy, a world-class journal in the energy science field, on June 15.

[Academics]Professor Choi Chang-hwan's Team Develops a New Material for Steel-genetics that Is Diversifiable into 3D Flash Memory Devices

Professor Choi Chang-hwan, Division of Materials Science & Engineering, and Dr. Koo Bon-cheol, a research team student, have developed a new material that can solve the high-density and low-power problems of 3D flash memory devices. This research has been highly praised for opening up the possibility of reducing flash device thickness, which is a task that must be overcome in order to continuously upgrade current 3D flash memory devices. Current 3D flash memory devices use thin-film materials consisting of oxide, nitride, and oxide (ONO) to store memory. This film has a thickness of 20 nm. 3D flash memory devices need continuous enhancement to improve their performance. However, it is difficult to reduce the thickness of existing ONO thin-film, and it is not easy to improve the speed and power of the flash element. In addition, alternative thin-film materials need to be developed due to difficulties in multi-level cells (MLCs) that can store various information in one cell. Professor Choi's team cooled an aluminum-coated substance in Hafnium oxide (HfO2), forming a new thin-film with residual polarization and an avionics field, maximizing the properties of the steel electrode. Flash memory devices with this feature are highly desirable as they can easily be repaired using improved polarizing properties. Moreover, the thin-film thickness can be implemented even if it is under 10 nm. Also, the properties of the steel-genetic have been improved as they induce a stable orthorhombic phase through high-stress deformation. Not only that, but Hafnium oxide is also a material that has been proven to be reliable in the field of logic semiconductors. Manufacturers being able to manufacture new Nand flash memory using this material without further investment is a significant benefit. This study was conducted by a team led by Professor Song Yun-heup, Department of Electronic Engineering, with the support of Samsung Electronics' Future Technology Development Center. It was introduced at a symposium on very-large-scale integration (VLSI) by the Institute of Electrical and Electronics Engineers (IEEE), a world-renowned association on semiconductors, which ran for six days starting on the 14th. In particular, this study was chosen as one of the "highlighted" theses by the technical committee and was introduced to the media, allowing it to gain the spotlight. The Symposia on VLSI Technology and Circuits, which celebrated its 40th anniversary this year, is the most prestigious conference in the field of semiconductors, along with the International Electron Device Meeting (IEDM). Annually, the conference presents the latest research on semiconductors and selects the papers that have contributed the most to semiconductor companies and academia. This year's conference was carried out online due to COVID-19 and received the most theses in 10 years. Out of the 248 papers that were received, 86 papers were selected as the most influential thesis of which only 29 papers were sponsored by universities"?). Professor Choi said, "Technology to implement strong-genetics is emerging as a trend in academia," and he added "this is the first good example that has raised the generation of Hafnium oxide material, which will be used for NAND-flash high-density integration, to nearly universal level." In addition, he mentioned that "Out of the 8 ferrogenic thin-film thesis papers that were chosen, 5 were from companies and 3 were from universities". He said, "The research team from Hanyang University was the only Korean university to have a thesis selected," and added "it is rare to present a research conducted by university without any cooperation or sponsor of enterprises. This study is expected to contribute to the development of the thin-film that can be implemented in 3D flash memory devices."

[Academics][Researcher of the Month] Effective Use of Photocatalysts to Combat Environmental Problems

Numerous attempts have been made by engineers to apply technology to our everyday problems. Professor Park Jae-woo (Department of Civil and Environmental Engineering) tackles one of the most critical problems of our time, environmental pollution, using the special characteristics of nano photocatalysts. His research focuses on resolving the problems caused during the reduction-oxidation process of photocatalysts. Through his research, he has discovered that the use of the Charge Transfer Layer (CTL) is significantly effective, and expects the findings to help organic pollutants decompose through photocatalysts, which will lead to a cleaner society. For the past 15 years, Park has been conducting research on the development of magnetic-cored dendrimers and nano-photocatalysts for the purpose of environmental purification. According to Park, nano-photocatalysts have the power to commence oxidation in hazardous substances by separating electrons from holes. This process of oxidation converts substances into water and carbon dioxide gas, which are harmless to the environment. However, despite their striking capabilities, photocatalysts have their shortcomings. In his research, Park focused on compromising with the photocatalysts' technical problem. For the past 15 years, Professor Park Jae-woo (Department of Civil and Environmental Engineering) has been conducting research on the development of nano-photocatalysts for the purpose of environmental purification. The problem with the use of photocatalysts One of the biggest disadvantages of using the reduction-oxidation of photocatalysts is that electrons have the tendency to return to their respective electron holes. Their tendency to recombine after separation lowered the rate at which photocatalysts oxidized harmful substances, and many researchers have sought out ways to prevent the recombination of electrons with the electron holes. The existing methods such as doping, facet, and core-shell merely slow down the rate at which electrons recombine with electron holes and fail to completely separate them. However, Park has succeeded in permanently separating the electrons using the CTL. How was CTL used? A photocatalyst which utilizes the CTL is comprised of three components: the photocatalyst which forms a pair of electrons and electron holes, the CTL which moves the electrons selectively, and the collector which accumulates and stores the moved electrons. Here, the CTL, being the main component, carries the electrons while inhibiting their passage through electron holes. As a result, the electron is moved from the photocatalyst to the electron collector, and suppresses them from recombining. What makes Park and his team’s accomplishment so unique is the fact that their work did not stop at only delaying the recombination, as previous methods had done, but also entirely prevented recombination by separating the electrons and shutting down the reverse-travelling by maintaining a high level of catalyst reaction. The result of the research “We have conducted two experiments to prove there is an increased activation of catalysts by using the CTL in the mentioned study,” said Park. He continued, “The first, is hydrolysis. A catalyst under the influence of the CTL displayed 78% higher hydrogenative yield than the existing one in the visible ray photography. Then, in the experiment with the subject bisphenol A, which is an organic pollutant, the catalyst showed a very high 93% removal rate after three hours of reaction." Park also believes that catalysts utilizing the CTL can be applied to energy and environment-related fields in an extensive range. Park said, “I want to thank my graduate school students, whose effort and sweat have made all this possible.” Park expressed gratitude to his graduate school students, whose effort and hard work have made the project possible. “It motivates me to reflect on my mindset when I see students working so hard on the research topic.” He especially thanked Hassan Anwer (Civil and Environmental Engineering, Doctoral program) for his devotion to the research.
