[Academics]Hanyang University 4th Industrial Revolution Research Center registers a patent for efficient dust purification of underground tunnels

Hanyang University's Fourth Industrial Revolution Research Center registered a patent for efficient dust purification of underground tunnels on August 31. Professor Cho Byung-wan in her class The Hanyang University Industry-University-Research Cooperation Foundation completed the registration of a patent (patent registration number 10-2144020) for underground spaces using quantum energy fields and waterfalls, natural ventilation methods of tunnels, and purification systems. This is the result of a study by Professor Cho Byung-wan, the director of the Fourth Industrial Revolution Research Institute and a professor in the Department of Civil and Environmental Engineering, to solve the fine dust problem in underground tunnel spaces, such as subways, which is one of the causes of fine dust in Korea. Along with the recent increase of subway construction, the number and length of tunnels has increased, causing air inside the tunnels to flow into the outlet without being ventilated properly with the outside and not purified, causing urban fine dust. The air inside such tunnels contain a number of pollutants that are harmful to the human body, such as micro dust, nitrogen oxides (NOx), sulfur oxides (Sox), formaldehyde, and volatile organic compounds (VOCs). In the case of subways, most of the operating sections are made of underground spaces, which by the piston effect causes train wind when the train enters or leaves the underground station. Such train winds are threatening the health of citizens as fine dust enters the platform through cracks in the screen as well as causing noise, resulting in major air pollution in the platform and on the train. To purify the air inside the tunnel, a jet-fan is installed inside the tunnel and filters are applied in ventilation facilities to filter pollutants. In general, expensive purification filters are rarely used due to huge operating costs and noise problems caused by huge electricity consumption of fan-type dust collectors. Fine dust collection vehicles and cleaning vehicles are operated as temporary measures if necessary, but the actual purification effect is insignificant. The patent describes the natural ventilation methods and devices that maximize the flow of the energy field-based Bernoulli fluid, which is identified by the new advanced quantum mechanics by applying advanced scientific technology in the era of the fourth industrial revolution. Furthermore, it also provides technologies for increasing the flow rate of polluted air inside the tunnel using the sectional change through the dust collector and natural ventilation methods and devices for underground space tunnels using plasma and waterfalls that purify the internal air in real time through quantum energy field-based nano plasma light falls or nano hydrogen antioxidant spray falls in the space of the tunnel. Professor Cho said, "We will consult as the world's first scientific system to solve the serious global fine dust problem in subways including developed countries, so that it can be extensively used in the construction of subways, roads and underwater tunnels around the world with the technology of the fourth industrial revolution, so that it can become a breakthrough in Korea’s construction and management of tunnels."

[Academics]Joint Research Team of Professor Yoo Won-chul Developed High Energy Density Foldable Super Capacitor

The joint research team of Hanyang University's Professor Yoo Won-chul of the Department of Chemical and Molecular Engineering and Inha University's Professor Lee Keun-hyung of the Department of Chemical Engineering developed a solid supercapacitor that has high energy density. The supercapacitor is a reinforced form of capacitor, especially reinforcing the capacity of electricity among the capacities of a condenser. The electric charges are stored on the surface of porous electrodes, by absorption and desorption of electrolyte ions. This leads to having high power density and fast-changing and discharging speeds. However, the existing supercapacitor had limited applications of its use due to its low energy compared to batteries. It was mainly used as a power aid in electric vehicles. The joint research team drastically improved the energy storage characteristic of the supercapacitor by using porous carbon with three-dimensional connective structures, which was designed to facilitate the ion movement and ionic liquid-based polymeric electrolytes that have high electrochemical stability. The team also developed a foldable supercapacitor that can be adjusted to various sizes and shapes by applying polymeric electrolytes. The capacitor operates without any changes in performance even when fully folded, raising the possibility of being used as an energy storage device for wearable electronic devices that have been actively researched and developed. This research was conducted with the support of the National Research Foundation of Korea and was published on the cover of Advanced Functional Materials volume 30, issue 30, on July 23, 2020.

[Academics]Joint Research Team of Hanyang and Kyunghee University Redefined New Gene Cause of Rheumarthritis

6 New Gene Causes of Rheumarthritis (SLAMF6, CXCL13, SWAP70, NFKBIA, ZFP36L1, LINC00158), an autoimmune disease that destructs itself, has been found along with a new gene cause (SH2B3) that is found exclusively in East Asians. Professor Bae Sang-chul The joint research team led by Professor Bae Sang-chul of Hanyang University Hospital for Rheumatic Diseases Department of Rheumatism and Professor Kim Kwang-woo of Kyunghee University Department of Biology, participated in by the Center for Genome Science under the Korea National Institute of Health and other university hospitals in Korea, published the above facts in the Annals of Rheumatic Diseases on July 28th. The research was conducted through rigorous analysis of the genome genetic drift of both patients and non-patients of rheumatism in Korea, using the Korean Chip technology that has been developed by the Center for Genome Science under the Korea National Institue of Health. Furthermore, through computational biology based on genetic drift, transcriptome, and the epigenome, the research team also clarified that the genetic drift related to rheumatic diseases can also be part of the cause of the disease in the tissues of the lungs and small intestine. Rheumatoid arthritis is an autoimmune disease that is caused when the immune system abnormally attacks the body tissues. This causes inflammation and pain around the joints and the tissues around them, also leading to possible permanent disability or organ damage caused by joint deformation. Rheumarthritis is known to have a high prevalence rate and therefore leads to an economic burden for patients. The cause of rheumatoid arthritis is a combination of many genetic variants and environmental factors. Bae Sang-chul President of Hanyang University Hospital for Rheumatic Diseases mentioned that "due to this discovery we were able to understand the development mechanism of rheumatism," and added that "genetic variants like this can be used to predict and diagnose rheumatism, allowing for more specified and advanced treatment of the disease." Also, this research holds a bigger meaning since "it provided a clue to the existing studies of genetic characteristics regarding the effects of the mucous membrane of our lungs and small intestine on autoantibody production." The research was conducted through the support of Hanyang University Research Institute for Rheumatology Research, the National Research Foundation of Korea, the Ministry of Health and Welfare, and the National Institute of Health. The first authors of the research are Dr. Kwon Young-chang (Hanyang University Institute for Rheumatology Research), student Lim Ji-woo (Kyunghee University Departement of Biology), Professor Bang So-young (Hanyang University Guri Hospital), while Professor Bae Sang-chul and Kim Kwang-woo participated as joint corresponding authors.

[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 alex684@hanyang.ac.kr

[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 whitewon99@hanyang.ac.kr

[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 (https://www.youtube.com/watch?v=L1exSp00ZJg) 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.
