[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][Excellent R&D] Building a System for Urban Ecosystems

When engineers did urban planning in the past, the feasibility and economic efficacy that it would bring were the top priorities. Recently, however, there has been increasing attention given to environmental factors, and the research on urban ecosystems has gained popularity within the field of urban planning. Professor Oh Kyushik (Department of Urban Planning and Engineering) is building up a spatial decision support system to maintain and manage urban ecosystem services. Professor Oh Kyushik (Department of Urban Planning and Engineering) is creating a platform for the maintenance and management of urban ecosystem services. Oh’s project aims to make a platform that assists with the decision-making process of the government. “What I am trying to do is to connect developmental and environmental issues in one framework,” explained Oh. The professor presented four standards in providing ecosystem services: resilience, buffer power, carbon storage capability, and heat stress mitigation capability. Considering these four standards, Oh collected research data provided by the collaborating labs and incorporated them in a readily accessible platform with an easy-to-use interface. Oh collected research data provided by collaborating labs and incorporated them into a readily accessible platform with an easy-to-use interface. Previously, Oh has been in charge of two national-level research and development projects conducted by the Ministry of Land, Infrastructure, and Transport. However, this was his first time participating in a project conducted by the Ministry of Environment. "The two ministries have some common ground but see from different points of view,” said Oh. He said he was determined to learn and combine both standards through this project. Oh revealed his will to make his research beneficial by reflecting the views of both the Ministry of Land, Infrastructure, and Transport and the Ministry of Environment. Oh reminded the members of Hanyang to look with eyes wide open at the past, but more importantly at the future. “I feel the world is changing at a rapid pace, especially after the coronavirus outbreak,” said Oh. The professor said that the field of urban planning is changing in parallel, as it is a discipline that is deeply related to the daily life of the public. Oh advised students to keep a broad vision and to build up extensive knowledge for the future. Oh Kyu-jin

[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][Excellent R&D] Standing at the Center of Cutting-Edge Technology

Although there have been notable advances in the study of natural science, research related to high pressure has not been active in Korea due to the lack of groundwork technology. Professor Kim Jaeyong (Department of Physics) is opening up the route to high pressure research through the HYU-HPSTAR-CIS High Pressure Research Center, the hub of collaboration between the world-class institutes. Professor Kim Jaeyong (Department of Physics) is paving the way for high pressure research in Korea. The HYU-HPSTAR-CIS High Pressure Research Center was established in 2016 with support from The Ministry of Science and ICT. The research center is in a collaborative relationship with the Carnegie Institution for Science (CIS) of the United States and the Center for High Pressure Science and Technology Advanced Research (HPSTAR) of China. The three institutes are consistently sharing their research outcomes by holding joint symposiums and reinforcing researcher exchanges. Kim explained the collaboration as “a successful case of acquiring advanced technologies by bringing in world-class institutes,” referring to the research spirit of the center as “Moon Ik-jeom spirit.” Moon is a historical figure who brought cottonseed from China into Korea, allowing the country to produce and distribute cotton to citizens. Just as Moon did in the past, Kim attained three diamond anvil cells, high pressure devices that enable the compression of a small piece of material with extreme pressure, from HPSTAR in 2016. Within a short period, Kim succeeded in producing a unique version of the cell. The center’s main focus is on hydrogen energy storage. The have recently reported successful results in the reversible storage of hydrogen energy. By imposing high pressure in Ti-Zr-Ni Quasicrystals, the research team was able to keep 4.2 wt of hydrogen at room temperature. Kim hopes that the results will contribute to the commercialization of hydrogen-powered cars. Kim hopes to contribute to the commercialization of hydrogen-powered cars with his recent research. Kim has demonstrated his will to help position the HYU-HPSTAR-CIS High Pressure Research Center as the hub of high pressure research. Kim also encouraged more students to participate in the research. “Our university has sufficient human resources, research conditions, and support systems to conduct the research,” said the professor. “I hope the students can feel the sense of thrill that comes from standing at the center of cutting-edge technology.” Oh Kyu-jin

[Academics][Researcher of the Month] From Seawater to Fresh Water

Droughts and water shortages are serious global threats. However, many technical developments are in progress to resolve these problems, and one of them is desalination. Desalination is the process of separating the salt in seawater from the water in order to get usable fresh water. However, the currently available technologies have the problem of sustainability, for they require fossil fuel and costly factories to be constructed. To suggest an alternative, Professor Kwak Rho-kyun (Department of Mechanical Engineering) is researching electro-membrane desalination. Professor Kwak Rho-kyun (Department of Mechanical Engineering) has been working on the topic of electro-membrane desalination for 10 years. Electro-membrane desalination uses the division of positive ion and negative ion when salt dissolves in water. The positive and negative ions are drawn to each pole when voltage is applied. Intersecting the membrane that makes each ion between electrodes pass through, called the exchange membrane of positive and negative ions, salt ions can be collected and removed. What is left is fresh water with the saline ions removed. Kwak has been working on the topic for 10 years, since he was a doctoral student. He said he first began his research inspired by the idea from his Ph.D. advisor that the unusual migration phenomenon of biomaterials such as DNA and ions would also occur in the electric membrane desalination system. His first goal was building a system of electro-membrane desalination to check whether the migration of biomaterials such as DNA and ions appear in the system of electro-membrane desalination, and visualizing the migration of the ions inside. Based on the visualization research, Kwak studied various subjects such as improving the efficiency of existing desalination devices and of treating the produced water. Kwak expressed special gratitude toward his graduate students who have helped him throughout the research process. Kwak said the significance of the study lies in that it developed a promising futuristic desalination technology, enabling Korea to become a global powerhouse to solve the future water shortage problem. Kwak’s innovative research has been highly acknowledged, introduced in journals like PRL and JOFM and others on the topics of desalination and water research. Kwak also expressed gratitude toward his graduate school students who have helped him throughout the research process. “I really want to thank my students. Their hard work was what made it possible to achieve such good research results,” said Kwak. Hwang Hee-won

[Student]Hanbok Beloved Worldwide

From 4th of January to 9th of January, hanbok making class was held in Human Ecology Building by Won Young. She has studied about hanbok and designing at Hanyang University (HYU) while attending Department of Clothing and Textile. The classes were held two hours everyday excluding the weekends, for four times. How it all started Won Young is Malaysian Chinese and also a Korean gyopo. While she was living in China, she says that there used to be a lot of tribes wearing different types of traditional clothes which is when she first encountered hanbok. “I have seen hanbok a lot on the television but once I came to Korea, I couldn’t see anyone wearing it in real life,” Won said. In order to make up for the discomfort of the hanbok, she started studying about life hanbok and became interested in the designs. Won (right) teaches Helene (left) how to use the sewing machine. She has created a startup team called TS (Time and Space) which consists of two people at the moment. Since she has studied in the field of fashion, Won thought of creating a brand of her own or creating a platform. Although there used to be websites where flower printings were available, it seemed to be a waste to cut out the pieces while designing her own patterns. This is how Won came up with the idea of DIY fabric in which she designs her own patterns and inserts the prints within the patterns. While attending at HYU, Won has participated in diverse programs created for international students but she felt that something was missing. “It seems like I was just looking around rather than doing something at the complete experiencing level. I think there are a lot of foreigners who would think like me,” said Won. This is how she came up with the idea of hanbok making class. Reactions towards the program A total number of fourteen students from diverse countries have participated in this program. Cho Yu-jin (faculty at Department of Clothing and Textile) and Lee Ye-jin (acquaintance of Won) have helped out with this event. Cho has helped out with the over lock while Lee has helped with the translation with the foreign students. Since the students participating in this program did not have any experiences or were not related major to fashion or designing, they had a hard time putting this together and one of them had to do all the sewing all over again from the sketch. Renu (left) and Azira (right) enjoys the program. Most of the students who have participated in the program had a similar idea in a sense that they were not aware of hanbok and how it could be utilized in daily life as well. Hwang An-ki (Media Communication, 2nd yr) said, “I was not well aware of Hanbok in the first place but as I was making it, it came to me as a beautiful traditional clothing.” Since foreign students who do not return to their home countries have not much to experience, they all claim that it has been a great experience for them. “I think it’s quite interesting that some people still wear traditional clothes since we don’t have them in Denmark. I think hanbok is very beautiful costume,” claimed Helene (Korean Studies, Master’s program). Although it has been a short period of time, all the students were able to finish their hanboks. After the session has finished, participants have matched their casual clothes along with hanbok and had photo session afterwards. “Through making the hanbok, foreign students would have been able to have the sense of achievement and feel the traditional culture of Korean costume. Also, by being able to have felt a new type of experience of making clothes, some people would have found a new hobby as well,” added Won. The students who have participated will keep in contact with each other and exchange information on hanbok flea markets or Korean culture experiences. Through this program, foreign students now understand Korean culture a little more. Since it has been a greatly developed program where it has been a talent donation of Won, students from diverse countries were able to experience the beauty of hanbok. Won hopes that she could carry out more programs related to hanbok in the future as well and provide lessons as part of the Korean wave towards foreigners.
