[Faculty][ERICA’s Power]Department of Transportation and Logistics Engineering Professor Lee Gun-woo, who Returns to His Alma

From student to professor! Transportation expert returns to his university Professor Lee Gun-woo in the Department of Transportation and Logistics (Department of Transportation Engineering, Class of '96) Professor Lee Gun-woo, who was appointed at the beginning of the year as a professor in the College of Engineering Sciences' Department of Transportation and Logistics, set out for a new challenge. He has come back to his alma mater, where he spent his college years actively participating in school clubs and the student council, as a professor. Let’s meet Professor Lee, who says that he will be faithful to education and research by maintaining communication with students at his alma mater. ▲ Professor Lee Gun-woo in the Department of Transportation and Logistics Engineering (Department of Transportation Engineering, Class of '96) Looking forward to meeting his students as his juniors and as pupils Professor Lee Gun-woo, who was appointed last March is an alumnus of the ERICA Department of Transportation Engineering, class of '96. After graduating from MIT and finishing his studies at the University of California, Irvine, he has been responsible for research in shipping, harbors, and international distribution for five years at the Korea Maritime Institute (KMI). In 2007, he worked as a professor in Chung-ang University's Department of International Logistics and came back to his alma mater this year as a professor in ERICA's Department of Transportation and Logistics Engineering. “The Department of International Logistics is affiliated with the College of Business and Economics, which has economics as its base. Because my academic background is in engineering, there were some disparities. There have been limits to practicing 100% of what I have studied until now. Just in time, I was able to transfer thanks to a request from my alma mater, Hanyang University.” His goals are unique as it is his first year working as a professor at his former school. Although working at the university he graduated from feels comfortable, there is more pressure from the thought of needing to lead his students, who are both his juniors in school and his pupils. Unfortunately, however, he is not yet able to have face-to-face classes with his students due to COVID-19. Even though his teaching is being done online, he simultaneously felt both comfort and anxiety when conducting his first lecture. “I could not foresee to what extent students would be able to follow along. There was also the problem of online lectures. The saddest thing is that I do not get to meet the students. It is unfortunate that I cannot meet them in person, communicate with them, get feedback on what they do not understand, and help them understand better. After all, there are limits to listening to what students think through email and phone calls.” The preparation process for online lectures is also quite burdensome. It takes about twice as long to prepare materials, record the lectures, edit, and upload them. There are sometimes situations when errors occur, such as his voice not being heard due to microphone errors. While this is not familiar work, he is gradually adapting to it through trial and error. ▲ Professor Lee Gun-woo is leading a research project in Transportation and Green Logistics through the Sustainable Transportation and Logistics Laboratory Concentrating on sustainable transportation environment and green logistics Hanyang University's Department of Transportation Engineering was first established in Korea in 1988. The pride of the alumni are so great as well. It was reorganized into the current Department of Transportation and Logistics Engineering by emphasizing the role of logistics in 2012. The subject which Professor Lee Gun-woo teaches is in the field of logistics. Similar to transportation, logistics has multidisciplinary characteristics. Perspectives change according to the point of view. In humanities logistics expands on the basis of trade, and in industral engineering and transportation engineering it expands into the field of engineering. Professor Lee is lecturing in the current department on "Transportation Logistics Economics" and "Sustainable Transportation and Green Logistics" in graduate school. From the second semester, he will provide lectures on "Logistics Management Engineering," "Logistics Systems Design," and "Special Lectures on Logistics." In the "Sustainable Transportation and Logistics Laboratory" that he is operating, students conduct research on the transportation environment and green logistics. Public health research includes atmosphere pollution emission estimation research, atmosphere diffusion analysis research, research on the effects of air pollution on humans, public convenience and ripple effects of transportation management techniques, and transportation logistics eco-friendly policies. It also includes effect analysis research on the introduction of new technology in the transportation and logistics field, such as eco-friendly transportation systems like electric cars and autonomous vehicles. According to Professor Lee, “It is research favored by the public but not government officials or businesses.” However, the interest and importance of this field will increase as international societies emphasizing eco-friendliness such as green-house gas reduction. Professor Lee’s most memorable achievement among all his research is receiving the Pyke-Johnson Award which is awarded in the transportation planning and environmental field as one of the five academic awards givem by the US Transportation Research Board. At the end of his PH.D program in 2010, he was awarded for his first SCI paper. He said that “it was the result of the help of Professor Stephen G. Richie who led his doctoral program, an excellent education provided by the department professors, and his fellow colleagues who participated in the doctoral program.” The Pyke-Johnson Award is the oldest award and has the highest authority in the transportation field, which can even be called an honor to one’s family. At that time, his award became a big issue in his college because it was the first award in the 30 years in the department. ▲ Professor Lee Gun-woo, who set his first step as a professor, senior, and teacher this year in ERICA showed his unique goal Educating the right expert with skill and humanity The changes to the ERICA Campus are truly amazing compared to when he first came to the school 24 years ago. To a great extent, the changes could be called "convulsions of nature." Professor Lee was amazed at the scenery and said, “The campus landscape is well organized, with many new buildings,” and that he "can feel the school’s enormous development in my skin.” Then, what was his most memorable experience when looking back at his college years? He choses "treet cafes" as the answer. The first words of his colleagues was the same when they heard he was appointed as a professor at his alma. “It has become a memory that I cannot forget now. When I was in school, there were lots of potholes on concrete pavers in front of the main entrance because it was a time when school peripheries were not yet developed. There, we collected branches and made campfires. Then we drank, sang, and debated with colleagues and our seniors.” One strength of Hanyang members that he has experienced and observed is their diligence. There is a tendency to overcome difficulties instead of running away from them. This is one of the reasons why numerous alumni are actively working in unimaginable fields all over the world. What he emphasizes to his students as their school senior and as their professor is humanity. Professor Lee underscores that he wishes "to educate proper experts with great humanity” and that “one can be responsible for their position if they were told that they have a great capacity for humanity.” That is why he helps students with etiquette and manners that are needed in social lives such as writing emails that do not convey rudeness. “Sometimes, I receive two-line emails without indicating one’s identity like sending a text message. Most of the time, it would be the case that students do not know how, but in real society that should not be done. In the past, I have shown students' emails as examples of etiquette. Since then, the students’ emails have changed. I try to teach these small but important factors to students whenever I have time.” He plans to talk more about students’ future careers. That is because of what his professor told him was of great help when he was a university student. “I want students to have their own dreams. While in university, I want them to find what they like and live a life that does not make them give up their dream.” Professor Lee highlights that he will be more faithful to education and research as a new professor. He plans on making opportunities to contribute to society when professional advice or an opinion on the transportation and logistics field is needed. We look forward to his future achievements and are cheering for his new start at his alma mater.

[Faculty][ERICA's Innovation] A Healthy Society Comes from Healthy Communication, Professor Lee Byung-kwan, Department of Advertising & Public Relations

A healthy society comes from health communication, Professor Lee Byung-kwan, Department of Advertising & Public Relations The world is going through chaos because of the COVID-19 pandemic. In times like this, accurate communication is essential. Professor Lee Byung-kwan, a first-generation health communication researcher in Korea, warned that it would be difficult to overcome the crisis if rapid and active communication is not conducted. ▲Professor Lee Byung-kwan, Department of Advertising & Public Relations WIth COVID-19, what is the role of communication? The Wall Street Journal highlighted Jeong Eun-kyung's consistent honesty, information-based analysis, and composure as powerful calmatives for Koreans. Professor Lee Byung-kwan, a health communication expert, gave a positive assessment from a different perspective. "Epidemiologists and medical professionals tend to only deliver the threats of diseases scientifically and objectively. However, the public cares more about the dangers that they present to individuals and their families. Unlike previous infectious diseases, they have fully understood the needs of the public and have been conveying information that the public is curious about." Having said this, Professor Lee praised the quarantine authorities for giving briefings every single day since the outbreak of COVID-19. Delivery of accurate information is important to prevent the public from being biased against fake news. This phenomenon is called the "Negative Dominance Model." "During a pandemic, the government should manage two things at the same time. One is quarantine, and the other is the delivery of accurate information via communication. Otherwise, the public will overestimate the threat and get anxious. On the contrary, they may underestimate the threat and react negligently." A very good example of social panic occured during the MERS and swine flu outbreaks. Fake news that spreads excessive fear and anxiety during a pandemic is another virus that needs to be eradicated. ▲ Professor Lee Byung-kwan is putting forth efforts to strengthen students' abilities to foster sincere social skills Building a Platform to Discuss Domestic Health Communication Professor Lee Byung-kwan's research field is health communication. It is the field of exploring communication strategies to enhance the health of our society. In other words, it is a field of communication that "provides information", " influences others", "provides motivation", as well as "reflects attitude and behavior", and "strengthens competence" in relation to the health of individuals and society. There are many topics that directly relate to the health of individuals and society, such as treatments and responses to problems like AIDS, obesity, drunk-driving, dating violence, smoking, and so on. Politics and medical and pharmaceutical industries are also included. Although the research field is diverse, we are able to see that all these topics are closely related to our lives. Over the past decade, the importance of health communication has been increasing alongside diseases like swine flu and MERS. However, ten years ago, Korea did not have a platform for health communication. In fact, Professor Lee Byungkwan was only able to encounter the field of health communication when he was in America for further studies but did not pay much attention to it. However, he got interested in this field while conducting research on AIDS and family planning campaigns in Africa with his advisor. For this, he is very grateful to his advisor. ▲What is Health Communication? "The good thing about health communication research is that the subject and target of the study are not abstract. They are real and clear. I also have a little sense of pride that I am able to help in solving health-related problems." After returning to Korea, Lee, together with other professors, started a Health Communication Research Association which later became an official academic association in 2009 with Lee serving as the first Chairman. He also received a commendation for serving as an advisor to the AIDS/Tuberculosis Advisory Committee from the Disease Control and Prevention Center. Professor Lee Byung-kwan's field of interest is the evaluation of the effectiveness of various disease-related campaigns. Holding campaigns is important but calculating the impact of these campaigns is equally important. Last year, Lee offered a solution to measure the actual impact for a tuberculosis campaign which required the largest budget in Korea after smoking. "To measure the effectiveness of the campaign, we need to measure the behavior changes before and after exposure to the campaign. However, our daily routines are uncontrolled, which makes it difficult to assess the changes accurately. Hence, these methodological limitations should be overcome by statistical algorithms for more accurate results. The recent research studies have reflected this interest." In relation to this, Professor Lee published an evaluation of the tuberculosis campaign impact in one of the medical journals called the International Journal of Tuberculosis and Lung Disease. Currently, Professor Lee is carrying out a research study on Bayesian structural time-series mode algorithms to measure the impact anti-smoking campaigns have had over the last 5 years. ▲Professor Lee Byung-kwan, who served as the first president of the Korea Health Communication Association, is being credited for leading the development of health communication in Korea. Finding worth in the community Professor Lee Byung-kwan worked as a member of National Committee in Public Health Emergency Preparedness and Response in 2015 when MERS broke out and paid close attention to live social media messages. At that time, Lee was establishing a system to monitor social media data in real-time by using machine learning techniques when MERS broke out, giving Professor Lee the chance to help prevent the spread of MERS while collecting and analyzing the public's opinion at the same time. He also advised the Public Health Emergency Preparedness and Response team to monitor social media data steadily during the outbreak of COVID-19. As such, Professor Lee showed interest in data science that uses machine learning or AI as a method to study health communication. "Students who study social science tend to think that they are not real 'scientists,' but social science requires a scientific approach to explain social phenomena. Therefore, I always oppose arguments that are abstract and emphasize that students think theoretically with evidence." Professor Lee mentioned that studying health communication makes him naturally interested in medical services. He conducted an Industry Coupled Problem Based Learning (IC-PBL) project at Ansan Medical Welfare Social Cooperative last year. From conducting cooperative and community health communication cooperation classes with students, innovative ideas were found. To contricute to the community, Lee plans to create an "Ansan City Health Map" that provides health indicators for local members in Ansan.

[Faculty][ERICA’s Keyword] Ranked 6th in the World Among Experts in the Field of Marine Biomedical Research, Department of Marine Science and Convergence Engineering Chair-professor Kim Se-kwon

Continuous and passionate steps of the 6th ranked expert in the field of marine biomedical research Professor Kim Se-kwon of the Department of Marine Science and Convergence Engineering “There is nothing in this world that is achieved without pain. It is sometimes painful to achieve answers to certain things like studying, research, and work, but your efforts will eventually bear fruit if you concentrate with passion.” Professor Kim Se-kwon was awarded the International Scientist Award at the 33rd International Khwarizmi Awards Ceremony this year, which centers around world-class scientists. He was also selected as the 6th ranked expert in the field of marine biomedical research from the US medical field research paper evaluation organization. Let's think about what passion is through the story of Professor Kim Se-kwon, who is gaining worldwide recognition for his expertise and influence. ▲ Hanyang University ERICA Department of Marine Science and Convergence Engineering Chair-professor Kim Se-kwon Q1. As the chair-professor of Hanyang University ERICA's Department of Marine Science and Convergence Engineering, in which classes do you meet students? A1. The Department of Marine Science and Convergence Engineering deals with understanding and preserving future Earth environmental changes and the fast-changing characteristics of the marine environment in response to the national advancement of marine development-related technologies. I've decided to give two lectures to freshmen this year. The topic of the first lecture is "Know the ocean to see the future: Marine living resources that bring money from the 4th industrial revolution" and the second lecture is "Healthcare utilizing marine biological resources." I've also had presentation and debate sessions with graduate school students on the topic of "Exploring and developing physiologic substances from marine biological resources." Q2. Over the past 10 years you have published about 200 research papers regarding marine organisms in SCI-level international journals. What have you been researching about marine organisms? A2. In China, there is an antique pharmaceutical book called Chinese Herbal Medicine (華本草, 13 volumes) that is similar to Korea's Dong-uibogam. This book deals with biological resources, descriptions, and effects that have been used as medicines in China, and it identifies about 200 marine organisms that were used as medicines 500 years ago. However, because of the abrupt development of medical plant domestication technologies, fewer than 10 marine organism species are currently being used. I published a book called Marine Organisms and Herbal Medicine based on the information on the marine organisms that were written about as medicinal herbs in Chinese Herbal Medicine. Moreover, Korea imports most herbal medicinal materials from China, but it was revealed that their pesticide pollution is very serious. This is why I started research into creating herbal medicine materials(bio new medicine) from marine waters, which exists in our sea and is an untapped resource. I mostly examined the vitality by separating new natural materials from marine organisms, disclosed their structures, and sought to discover their application methods by realizing the effect mechanisms. As a result, I could discover diverse vitalizations such as anticancer, anti-aging, anti-allergy, anti-dementia, antidiabetes, and antihypertensive uses. Q3. You received an International Scientist Award at the 33rd International Khwarizimi Awards in February and also the 2019 Best Paper Award at the world-class journal in marine biomedical sciences field Marine Drugs. A3. The International Khwarizimi Award is an award that was established by the Iranian government in 1987 in honor of Muhammad Ibn-Musa al-Khwarizmi (770-840 CE), the first Persian mathematician and astronomer to establish the concept of algebra. It is an international award that selects award-winning journals of science and technology through the support of diverse international organizations such as UNESCO. A professor at the Iran Institute of Science and Technology read some of my research papers, became interested, and nominated me for a Khwarizmi Award. I did not expect to be awarded but was given the pleasure of winning the award. Different from other winners, I had other 4-day award schedules. So, I participated in invited lectures at the Iran Institute of Science and Technology and the Iran Institute of Ocean Science and Technology. Also, I was asked to give an advisory opinion by the SAFF Offshore Industries Company and discuss mutual cooperation methods. The reason why I received the Best Paper Award from Marine Drugs was due to the review paper that suggested the possibility of utilizing protein and peptides in the processing of residues that are thrown away after marine products are processed as functional cosmetic materials. I am aware that I was selected as the winner because the paper quotation rate was high worldwide. I am happy that I am gaining international recognition for the efforts I have made and results that I have found. Q4. Was there a special reason why you became interested in the marine bio-field? A4. In the ocean, there are about 300,000 species that amount to 80% of all animal species on earth, but more than 96% are unused resources. Some maritime states that are close to the ocean, along with some developed countries, are showing a trend of shifting the subjects of biomaterial development from land resources to unused marine animals. Korea, which is surrounded on three sides by ocean and holds maritime jurisdiction that is 4.5 times larger than its territory, has abundant maritime resources, but unfortunately is not using them properly. About 40 years ago when I started my research, only a scarce amount of resources such as fish and marine algae (seaweed, laver, kelp) were used as food sources, and other living marine resources were not used. There wasn't even basic research being conducted on marine organisms. Therefore, I established the Marine Biochemistry Research Laboratory and progressed with research in order to effectively use living marine organisms. Since then I have explored numerous marine organisms for new functional substances and disclosed their functions. Such research must be undertaken to utilize living marine organisms in diverse ways. Since systemic research through biotechnology is in an insufficient state, much pain and effort were required to overcome this problem. ▲ Professor Kim Se-kwon was awarded the International Scientist Award at the 33rd International Khwarizimi Awards Ceremony this year and was ranked 6th among world-class experts in the marine biomedical field by the US medical field research paper evaluation organization. Q5. You were selected 5 years in a row as the Highly Cited Researchers(HCR) in the world by the Global Academic Information Enterprise and were selected last May as the 6th (Top 0.0075%) highest ranking world-class expert in the biomedical sciences field by the US medical field research paper evaluation organization. A5. I have spent time as a professor with three obligations in my mind as a scholar. First, to teach students well, second, performing creative research, and third, providing help to humanity with research outcomes. I have never considered myself an extraordinary person. Therefore, I thought I should put forth a lot of effort as I do not have enough capabilities. I have received good results by doing my best and being focused on my work. Q6. You have published about 40 professional books in English regarding the marine bio field. A6. When I was a visiting professor at Memorial University in Canada in 1999, I came to know a professor who had published about 60 books as an editor and works worldwide. I once suggested we publish a book in my field as joint-editors, but unfortunately this wasn't achieved. So, after a lot of thinking, I decided to publish on my own. Luckily, I had experience evaluating many publication plans for foreign publishers, thus could publish my first English professional books in the CRC Press, which is a famous publisher in the US. This gave me confidence, which let me publish more than 40 books after receiving publication requests from many publishers. Q7. You have strived with ongoing passion in research, paper presentation, and book publishing. Do you have your own special know-how? A7. I have made more efforts and focused on my work than any other by constantly thinking about my lack of abilities. Because of this, I gained confidence and built an attitude to try out anything with confidence. In fact, it takes a lot of courage from people with degrees in Korea to publish English professional papers. Regardless, I eventually did it. I don’t think there is a special know-how in anything. Q8. Do you think marine convergence engineering and the marine bio field will play a big role in future society? A8. There needs to be a collective scientific approach in order to manage the ocean environment, protect marine resources, and use them valuably for humanity. Therefore, marine convergence engineering will be of more importance in the future. Moreover, in the case of Korea, which is surrounded on three sides by ocean, the marine bio field that uses marine living organisms will grow into a new power industry for the nation. Q9. Do you have anything to say about passion to ERICA members and young researchers? A9. I remember the four elements of happiness that contemporary people must hold, suggested by one author. One, language studies, two, building academic knowledge, three, playing instruments, and four, enjoying sports. When looking closely at these four elements of happiness, they all require pain and passion in order to be achieved. It reminds us of "no pain, no gain." Although there will be painful aspects to researching, working, and trying to find answers, the time you get to feel happy will come faster if you focus on your work with passion. Now, diverse opportunities for growth will come in technologically innovative businesses along with the 4th industrial revolution. In technical innovation, creative research is necessary. So, you must put passion into developing your creative research capabilities. That will be the key to solving your worries about employment or startups. ▲ ‘2019 Best Paper Awards’ by Marine Drugs Chair-professor Kim Se-kwon and marine biomedical sciences Marine biomedical sciences is a field that explores medical usability of physiologic abilities of marine living organisms. Professor Kim Se-kwon, who is a world-renowned marine biomedical expert, continued his research on disclosing the various effects of marine living organisms in fields such as anticancer, anti-aging, anti-dementia, anti-obesity, and anti-diabetes. He recently received the 2019 Best Paper Awards from the global journal Marine Drugs.

[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

[Alumni][Attention! Hanyang-in] Tenor Yoo Chae-hoon, Alumni of Phantom Singer 3, Turns the Tables and Wins

Korea's first crossover vocal audition program, Phantom Singer 3 ended on the 3rd. The program came to a successful end with about 500,000 text messages received during the live broadcast of the finale. Team "La Poem, which included alumnus Yoo Chae-hoon (Dept. of Voice, '07), won the title by creating a reversal in the live audience vote. Yoo, a graduate from Hanyang University's Department of Voice, canceled plans to study abroad and attending several audition programs such as Mnet's Trot X but did not stand out. He then decided to give himself one last shot and attended Phantom Singer 3, which welcomed him with a great response. His popularity increased after a perfect performance of "Il Mondo" from the movie About Time. After every round, participants queued up and begged to go on stage with Yoo. La Poem: Yoo Chae-hoon, Park Ki-hoon, Choi Sung-hoon, and Jung Min-sung (Source: JTBC) La Poem was made up of tenor Yoo Chae-hoon, tenor Park Ki-hoon, countertenor Choi Sung-hoon, and baritone Jung Min-sung. Leader Yoo played an essential role in this group's forming. Yoo showed amazing responsibility to the point where he mumbled his worries about the finals in his sleep, and his team members depended on Yoo mentally as well as for his musical parts. Before his last performance, Yoo said, "I want to be a good brother in the group who can create positive synergy both musically and mentally," showing his responsibility. The last performance focused on showing great teamwork and individual skills. Various genres such as pop and K-pop were tried out on stage. The first song, "Nelle Toe Mani" highlighted the grandeur of four people while the song "Shining" by Ja woo-rim highlighted the delicate expressions. They focused more on their individual musical colors rather than harmony in their third song "Madmoadzel Hyde," and for the last song, they chose "The Rose" with a message of "returning the love you have received." As a result, La Poem received the most audience votes out of the three groups in the first round, creating a reversal. La Poem consists of two tenors, one countertenor and one baritone. The biggest advantage is the stability that comes from the voices of the members, as it is a composition that can cover the full male vocal range. The combination of the high-pitched countertenor, two melodic tenors and the bass-like baritone allows this group to sing in any musical genres perfectly. In fact, they have proven that they are able to sing in various genres from K-pop to EDM, increasing the audience's expectations.

[Policy]ERICA Students Take Action to Revitalize Gyeonggi-do Local Business Districts

Hanyang University ERICA Campus, along with five other universities, is striving to revitalize local business districts in Gyeonggi-do. As a result of the Local Business District-University Cooperation Project selection council held by the Gyeonggi-do Market Commercial Promotion Agency on July 15, where participants included market development experts and professors of colleges of arts, it was announced that they will support the revitalization of local business districts with six universities in the province. The Local Business District-University Cooperation Project started last year along with the Local Business District Organization Service that the 7th local election in Gyeonggi-do is carrying out, and has the goal of developing a beautiful and unique local business district related to arts and design, in collaboration with universities. The universities selected for this project are Hanyang University ERICA Campus, Kyunghee University, Kaywon University of Art and Design, Kyungdong University, Daejin University, and Shinhan University, a total of six schools. Each university will be provided with 25 million won for business expenses to facilitate the self-perpetuating ability of local business districts. This year’s selected projects displayed unique ideas from students and were highly evaluated in terms of commercial district association, ripple effect, and feasibility. Hanyang University ERICA Campus will begin its cooperation hotline with Ansan's University Merchant Association and the ERICA Merchant Association, create a logo composite mark, and produce promotion video clips to revitalize business districts near the university as local community representative attractions. Gyeonggi-do intended funds to circulate within the local business districts by proving some of the student activity expenses in Gyeonggi local currency which is only allowed to use in Gyeonggi district. This year, the activity expenses have been doubled from last year to allow students to stay longer and work together in local business districts. Cho Jang-seok, director of the small business department said that “it is significant that local university students and merchants are coming together to identify the problems of local business districts and trying to solve them together,” and that “this project will be a stepping stone to gradually expanding the services of revitalized local business districts.” Global News Team global@hanyang.ac.kr Translation by: Park Gyeong-min

[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 alex684@hanyang.ac.kr

[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.

[Performance]Four Graduates of Hanyang University are Amongst the 70 New Law School Prosecutors for 2020

Among the 70 new prosecutors in 2020, four were undergraduate students from Hanyang University, placing Hanyang as the sixth-highest among other Korean universities, and five were graduate students from Hanyang University’s School of Law, the fifth-highest amongst other domestic law schools. On May 11th, the Ministry of Justice newly appointed 70 people who passed the 9th bar exam from the School of Law as prosecutors. This year marks the first time that more than 70 law school graduates-turned prosecutors have been newly appointed since 2012 when 42 people passed the first bar exam. This is due to the sharp decrease in the number of graduates from the Judicial Research and Training Institute. According to The Law Journal on the 18th, which published an analysis regarding the newly picked prosecutors, Seoul National University and Yonsei University had the largest number with 13, followed by Korea University with 12. Sungkyunkwan University and Ewha Woman's University were tied at 4th with five students each. Hanyang University and Sogang University tied for sixth with four students each. Also, after analyzing the newly appointed prosecutors coming from law schools, Pusan National University’s School of Law topped the list with nine students. Pusan National University’s School of Law ranked ninth with only two students last year but jumped to first place this year. Korea University’s School of Law (8 students) and Sungkyunkwan University’s School of Law (7 students) took the top three spots. Hanyang University’s School of Law had only three students appointed last year, but as the number increased to five this year, it rose to a joint fifth place with Kyung Hee University’s School of Law. Out of the 70 newly hired prosecutors, 41 (58.6%) were women, a sharp increase from last year (38.1%, 21 people). By age group, those who were in the 30-31 year-old group accounted for the largest portion with 27.1%, followed by the 28-29 year-old group with 25.6%, and the 32-33 year-old group with 15.7%. There were 22 (31.4%) prosecutors that majored in law for their undergraduate degree, while more than 60% were non-law majors. On the other hand, the Ministry of Justice announced that it had selected qualified candidates based on the results of personality tests, third-phase competency evaluations, and organizational competency evaluations in order to verify the candidates' in-depth public ethics, ethical awareness, balanced perspective and human rights awareness through document screening and working-level records in order to verify their academic performance and professionalism. The newly appointed prosecutors will receive intensive and substantial training such as but not limited to theory and practice of criminal law, prosecution investigation, lectures on investigative techniques, evaluation of working records, ethics education specifically for prosecutors, and working-level settlement of the frontline office (2 months), and will then carry out their duties as prosecutors.
