[Special]Hanyang Resumes Offline Lectures

Due to the coronavirus outbreak, all courses were switched to online for the first four weeks of this semester. However, the university resumed some offline lectures starting on April 13 – most classes were limited to experiment practice and theory practice courses. The administration is paying extra attention to prevent the community-acquired infection. The students, on the other hand, have shown varying reactions surrounding the resumption of offline lectures. The university has recently resumed offline lectures, most of which are experiment practice and theory practice courses. In order to hold offline lectures, professors need to file up the request to the Academic Service Team the week before their first offline class. The classes could be held after the approval of the students, the affiliated college, and the Infectious Disease Control Committee. According to the Academic Service Team, about 200 classes requested offline lectures at Seoul Campus. A total of 70 classes requested offline classes at ERICA Campus, 27 of which are personal lessons hosted by the Department of Applied Music professors. Still, the officials added that even after receiving permission, many classes continue to be conducted online. In order to prevent the spread of the coronavirus, there are a number of requirements before being allowed to attend an offline lecture. Before entering the classroom, students must be checked to ensure their temperature is below 37.5 degrees and fill out a self-health checkup form in front of the main gate. They are also required to wear masks in the classroom and wash their hands using hand sanitizer. Ventilation is also an important issue, as professors are encouraged to leave the windows and doors open. The participants – including the instructor – should maintain at least two meters of physical distance. Students should turn in a self-health checkup sheet and wear masks before entering the classroom. Students have expressed mixed opinions regarding the resumption of offline lectures. Nam Hee-joo (Department of Architecture, 5th year) preferred to have offline classes as she had more opportunities to receive critiques on her architectural designs. "There were lots of environmental limitations to getting enough feedback online,” said Nam. She added that offline classes motivated her to concentrate more on the professor’s lectures and comments. However, some of the students did not feel the same way. Kim Ki-young (Department of Jewelry and Fashion Design, 1st year) said that there was no notable difference between online and offline lectures. Kim said that he would rather choose to have more online classes considering his long commute time to school. Meanwhile, school officials said that they are making every effort to find ways to ensure the safest way to resolve the confusion caused by the COVID-19 outbreak. “The university believes that the health and safety of students and faculty members is the top priority,” said Oh Chae-young, a staff member of the Academic Service Team. “Please understand the inconvenience caused by online classes and the restricted access to school facilities as it is is a necessary measure to ensure our members' health and safety.” Oh Kyu-jin alex684@hanyang.ac.kr Photos by Kim Su-ji

[Special]Foreign Students' Stories During the Coronavirus Pandemic

During March, South Korea recorded the highest number of 909 confirmed new coronavirus patients in one day, which spread great anxiety among South Koreans. However, there was another group in South Korea that was subjected to the same –or perhaps worse- insecurities – foreign students. The social distancing policy, although necessary, inevitably caused certain inconveniences for citizens. The foreign students were no exception. Haoyu Zhang (Department of Computer Science and Engineering, 3rd year) picked the reduced public transportation operation period as one example. “The Seoul Metro System reduced the operation time limit to midnight starting on April 1, 2020, which interrupted my normal routine that requires travelling during late hours.” Haoyu Zhang (Department of Computer Science and Engineering, 3rd year) said the reduced time of operation of the Seoul Metro System has caused discomfort for him. (Photo courtesy of MSN news) Dalia Suliman (English Language and Literature, 2nd year) replied that exchange students currently staying in dormitories are struggling as well. Their main concern is the school’s uncertain schedule for re-opening. With many countries' borders closing up, many exchange students are at a crossroad to make instant decisions about whether they will leave the country and give up a semester or not. Due to unclear school curriculum, exchange students currently living in dormitories are having trouble choosing whether or not to return home. (Photo courtesy of TBS News) Nevertheless, the students said they are getting an apt amount of help from Korean society. Jing-ying Liu (English Language and Literature, 2nd year) explained she was able to receive ten free masks and some hand sanitizer from her study abroad institution which was provided to international students. Moreover, she receives alerts on her phone if she happens to get near a place where a confirmed patient has passed by. Haoyu Zhang added that he got a free coronavirus test when he had a symptom of the illness. He also received free alcohol sanitizing pads from his apartment's property management team and has been using them handily. Moreover, Yuen Hu (English Language and Literature, 4th year) said she received masks with filters from Hanyang International Affairs. The process was very simple and only required giving them her student identification number and signing the necessary documents. Jing-ying Liu's messages alerting her of a newly confirmed patient.

However, the students of Hanyang are paving their own way during this crisis with public support and living their Korean life the best they can. Lee Yoon-seo cipcd0909@hanyang.ac.kr

[Special]Students Return to Hanyang from Abroad

Countries worldwide are facing difficulties in saving themselves from the coronavirus pandemic, and the exchange students in the worst-hit countries were forced to cut their studies short and come back to Korea. Many students who came back are currently self-quarantined at home. Three exchange students of Hanyang talked about their stay in other countries and the process of returning home. No notice for international students - on top of that, racism Until last month, Lee Ye-ji (Department of Chemical Engineering, 3rd year) was a student of Reutlingen University in Germany. However, she came back to Korea on March 31. Lee’s classes were supposed to start on March 16, but she soon received a notice that the start of school had been postponed to April 20. Lee said she did not receive any additional notice about the exchange program, such as whether the school will offer online lectures. The orientation was also conducted briefly because gatherings of more than 200 people were prohibited. The situation worsened in Germany. From March 18, most stores were closed, save for ones selling daily necessities. Also, gatherings of more than four people were prohibited. As things worsened, Lee said she experienced severe racial discrimination. “When I walked on the streets, children and locals called me coronavirus and said 'Ni Hao' to me." According to Lee, most people did not wear masks due to the lack of supply. However, she had seen many people wear disposable gloves. At the supermarket in front of Lee’s dormitory, only a certain number of people were allowed in the store at a time. Also, they had to maintain the distance of 1.5 meters when they paid at the counter. The empty store shelves in Germany due to hoarding. (Photo courtesy of Lee) The journey home was exceptionally hard Kim Seok-ha (Department of English Language Education, 3rd year) attended Georgia State University in America, and came back March 25th. When Kim first arrived in America, the situation was not too serious. However, the government declared a state of emergency before long. Most schools changed the rest of the semester to online. The school dormitory Kim lived in recommended students leave the dormitory, with the exception of the international students. In the end, Kim decided to return home. Even while coming back to Korea, Kim experienced many difficulties. The most stressful part for Kim was that the price of the airline tickets had skyrocketed. “It suddenly rose more than three times. I had to pay an extra million won over the usual price.” Another hardship was that he was found out to have taken the same flight as a confirmed coronavirus patient, and was classified as a "close contact." Upon arrival, Kim had to stayed at a hotel before going to his house because taking public transportation to his hometown Daegu was prohibited. Having experienced it first-hand in two nations, Kim said he thinks Korea is dealing with the coronavirus better than America, especially in regards to the examination equipment. “Also, it was impressive to see how everyone is participating in preventing the spread by wearing masks at all times,” said Kim. The arrival line at the airport is unusually long due to thorough medical inspections. (Photo courtesy of Kim) Price for airline ticket skyrocketted. 10 million won? Lee Eung-chan (Division of Business Administration, 4th year) came back from the University of Iowa in America on March 20th. During her stay, Lee said she did not see many locals wearing masks. “Iowa did not have many confirmed cases, but more importantly, most Americans think that only patients wear masks. Also, even if they are encouraged to wear masks on a daily basis, supply falls short of the demand,” said Lee. However, many other things changed. Due to the government’s policy, most public institutions were closed. Restaurants only offered delivery or take-out. Lee explained having experienced difficulties similar to those of Kim. As the coronavirus pandemic worsened in America, the number of people returning to Korea increased, whereas the number of flights decreased. Therefore, the price of airline tickets rose to two million won. “Once, I saw the ticket prices even go up above 10 million won,” said Lee. The government offered relief goods for people subjected to self-quarantine. (Photo courtesy of Kim) Although their plans as exchange students floundered, the three students expressed a strong will to follow the school curriculum in any possible way. Some are preparing to apply for the exchange program again after the coronavirus. Being more grateful for their safe returns than being disappointed about the situation, they are considering ways to spend the self-quarantine meaningfully. Hwang Hee-won whitewon99@hanyang.ac.kr

[Special]Fact Check: Incorrect Rumors About Coronavirus

Alongside the disease, much information about the coronavirus is spreading around our society. More often than not, the information is incorrect. However, it is not easy for us to winnow out the facts from falsehoods. Professor Lee Keun-hwa (Department of Medical Microbiology) fact checked some of the wide-spread rumors about the virus to help Hanyangians better protect themselves. Lee Keun-hwa (Department of Medical Microbiology) Q. There are many types of coronavirus. A. The viruses evolved into two major strains, the “L” type and the “S” type. Although the S-type was found to be the ancestral version, the L-type is more prevalent than the S-type by approximately 7:3. This is because the L-type is relatively more aggressive and fast-spreading than the S-type. Nevertheless, the relative frequency of the L-type decreased after early January. Human intervention may have placed more severe selective pressures on the L-type as compared to on the S-type, due to its aggressiveness in transmitting itself. Q. In Italy, the coronavirus mutated into a form that is four-times stronger, and this will prolong the epidemic. A. There is no evidence that the coronavirus mutated into a more aggressive form in Italy. Still, the epidemic curve (the frequency of new cases over time from the onset of disease) is increasing in many parts of the world including Europe, the U.S., and Africa. So, there is a high possibility that it will be a prolonged battle. Q. Only KF94 masks can prevent the virus from entering the body. A: "KF" stands for "Korea Filter," so the higher the figure next to KF, the better it prevents the virus. Although the size of coronavirus is too small to be prevented with masks, wearing masks with a high KF does increase the blocking effect. Therefore, they are recommended. Q. It is possible to reuse the mask after heating it for 30 seconds and drying it in UV rays because coronavirus is weak against heat and UV rays. A. UV rays are used to sterilize viruses. They must penetrate parts of the mask to sterilize it, because UV rays have low permeability. The part that UV does not reach cannot be sterilized. When heating masks in the microwave, it is necessary to check whether the filter is damaged. If the outer part of the mask is damaged through the microwave, it cannot prevent the virus anymore. Q. You can get coronavirus just by touching objects or breathing air that a patient has touched or breathed. A. It is possible to get the virus through the air or coming into contact with contaminated objects. The virus remains stable for several hours to days in aerosols and on surfaces. Therefore, touching the belongings of a patient could increase the chance of infection. Q. Coronavirus can infect one through their eyes. A. Several reports suggest the virus can cause conjunctivitis and possibly be transmitted by aerosol contact with conjunctiva. In other words, if secretions of the infected person enter the retina of another person, the infection will be transmitted. A Hanyangian has his temperature taken before entering the hospital because of coronavirus. Q. Coronavirus is not fatal to young people. A. Coronavirus influences every age group. Statistically, elderly people are more at risk, but there will be excessive immune responses among younger people. Therefore, coronavirus can be fatal to young people as well. Q. Drinking hot water can prevent the disease. A. Coronavirus gets weaker when temperature rises, but it cannot be killed by hot water. So, drinking hot water will not prevent or cure the disease. Q. Once you get the virus, it causes pulmonary fibrosis, and you will have to be on pills for the rest of your life. A. Pulmonary fibrosis is a respiratory disease that causes severe respiratory problems due to the hardening of lung tissue. There is no medical evidence that patients of coronavirus are likely to get pulmonary fibrosis from the disease. Q. Development of medicine is difficult because the coronavirus mutates quickly. A. It is true. Coronavirus can mutate very fast, so it is a little hard to develop medicines when the mutations take place affecting the core parts of the medicine. Now, the existing medicines for Acquired Immune Deficiency Syndrome (AIDS), Ebola hemorrhagic fever, and Malaria (epidemics) are being tested to see whether they are effective against the coronavirus. Lee advises Hanyangians to prevent the coronavirus by refraining from meeting in an enclosed space, not participating in events, and keeping personal hygiene strictly by frequently washing their hands. “I hope the pandemic ends and all Hanyangians can come to school in good health,” said Lee.

[Special]Hanyangians Fighting Against Coronavirus

Angela Merkel, the Chancellor of Germany, said “Coronavirus is the biggest challenge since WW2.” The coronavirus crisis continues to put the world in fear with force corresponding to that of war. As of March 30, the number of confirmed patients in South Korea has reached 9,583, nearing 10,000. Confronted by a pandemic, many Hanyangians have been endeavoring in their own ways to combat the disease for a safer tomorrow. Professors Kang Bo-seung (Department of Emergency Medicine) set an exemplary case of stopping the infection in hospitals. During his work at Hanyang University Guri Hospital, a patient was sent to the emergency room for a fever. He was not tested for the coronavirus because he had no record of visiting China. Kang questioned him further and learned that the patient had been in contact with Chinese people in a conference he attended. The patient was later confirmed as the 17th confirmed case. Had it not been for Kang ’s persistent inquiry, the 17th confirmed patient could have been allowed access to the emergency room and the vulnerable patients inside would have been presented with serious danger. Kang Bo-seung (Department of Emergency Medicine) was able to stop the spread of the disease in the emergency room with wise inquiries. Jung Jae-yoon (Department of Organic and Nano Engineering) is also helping to combat the disease by giving away an antibacterial fabric-rinsing solution he made for the students. By adding 2.5 percent of the bottled solution into the washing machine with fabric softeners, it can kill 99.9% of the germs on the fabric, repressing the spread of disease. The antibacterial solution was given out in front of the campus restaurant. They ran out of stock in no time. Antibacterial Rinsing Solution distributed by Jung Jae-yoon (Department of Organic and Nano Engineering) to Hanyang University students. Alumni Kim Il-doo (Ph.D. in the Department of Materials Science and Chemical Engineering, ‘95), currently a professor at KAIST, gained enormous attention for his nano-textile mask. With masks running out of stock, there was an increasing need to make disposable masks reusable for a length of time. Kim invented masks that can be laundered and reused for up to a month. While the original masks use static electricity to filter out the fine particles and loses its electricity over a day’s use, nano masks only use nano textiles to block out particles. This way, they do not need to be changed often. The masks are awaiting approval from the Ministry of Food and Drug Safety to be commercialized. The Mask made by Kim Il-doo is reusable for a month. (Photo courtesy of KAIST) Meanwhile, Kim Jin-yong (M.S. in the Graduate School of Public health, N/A) was drew acclaim from around the world for proposing a drive-thru test facility. This diagnosis process is inexpensive and extremely time-saving, reducing the 20 to 30-minute process to just 10 minutes. On top of that, it minimizes contact between patients and the medical team. The idea was officially noted by President Trump and introduced into the U.S. Drive-thru diagnosis process currently being held in Goyang-si. (Photo courtesy of Joong-Ang Ilbo) Students Students of Hanyang University have also been making efforts against the crisis. Four students in the Department of Policy Studies started a fundraiser to donate urgently needed medical supplies in the name of Hanyang students. They initially planned to raise 2 million won. The goal was met within an hour, and within days, they were able to raise 22 million won which was donated to coronavirus-related charities. From the left, Kim Do-young, Shin Hyo-jung, Park Eun-bin, and Jo Sung-jae. The four Department of Policy Studies students organized a Hanyang fundraiser, raising 22 million won. Kim Ji-hoo (Department of Computer Science, Master’s program) created a coronavirus dataset. The dataset analyzes the various data related to the spread of the coronavirus which has been referenced by many data scientists around the world as the basis for predicting the virus’ future spread. He has remodeled all the information presented by the Korea Centers for Disease Control and Prevention (KCDC) to visualize, analyze, and predict the coronavirus networks. The system is currently being observed positively by many countries, with France even having their dataset based on Kim’s program. Kim Ji-hoo (Department of Computer Science, Master’s program) created a coronavirus dataset. Adversities have the power to bring people together.

[Special]Suffering Wangsimni After Coronavirus Outbreak

The atmosphere around campus is very different compared to previous years. Wangsimni in March is usually crowded with people, but this year, it has stayed dormant as if the winter holiday has not yet ended, bringing a striking change in Wangsimni's scenery as well as in the lives of the local restaurant owners and student residents. The usually-crowded Wangsimni in March is empty due to coronavirus. Normally, Wangsimni at this time would be buzzing from morning to night with new and old friends, social outings – and perhaps a few drinks. Another feature is the many events held by departments and student clubs at the beginning of school. However, due to the coronavirus outbreak, people have been refraining from going out and most events have been canceled. "This March has been a hard time to run a business,” said a restaurant owner in Wangsimni. As the virus went viral, the restaurant's sales plunged sharply. The owner anchored his hope on the quick decline in the number of patients. "Where there is a will, there is a way,” said the owner. "I just hope that everything goes back to normal as quickly as possible.” Most meetings and events have been canceled, affecting the local restaurant owners and students. Students are also feeling the change. Choi Soo-jin (Department of Education, 2nd year), a Wangsimni resident said, "When my department held an event in early February, there were quite a lot of people enjoying their night in Wangsimni.” However, towards late February, she could see a drastic decrease in the floating population. International students, on the other hand, viewed the situation differently. Liana Ivashynenko (Division of International Studies, 2nd year), who is an exchange student and was also in Seoul last summer, said that she could not see much difference. "One thing different is that people are all wearing masks,” said Ivanshynenko. Another foreign student, Zukhra Kamalova (Division of International Studies, Master's Program), said that she looks forward to the virus being contained soon and to finally see her new friends at school. Yun Hyuk-jin, the owner of Tip of the Spear, started a mask donation campaign for the underprivileged neighbors around Seongdong-gu. Meanwhile, some locals decided to voluntarily help their neighbors through the hard time, making for a heartwarming story. Tip of the Spear, a restaurant near the campus, has been featured in the media for holding a mask donation campaign. As the demand for KF masks has surged, vulnerable social groups had relatively less opportunity to buy the masks. Yun Hyuk-jin, the owner, made a donation box where people can donate their masks to the Seongdong-gu neighbors who are economically disadvantaged. The donors are offered a small order of roasted kimchi and pork in return for four donated masks. "When I was young, there was a gold-collecting campaign to overcome Korea’s financial crisis,” recalled Yun. That is when he learned that changes come from small beginnings. Yun said that approximately 200 masks were donated by the members of Hanyang and the local community. He looks forward to seeing more people participate in the campaign. “This will reflect the warmth of the community that is cooperating to overcome the coronavirus outbreak,” said Yun.

[Special]Professors Behind the Screen

Switching to online lectures changed many things for the professors. While students listen to lectures and study at home, professors come to school to record lectures in their various chosen ways. Behind the screens, Hanyang's professors continue to work tirelessly for students’ academic progress even during the pandemic. Interviewing Klaus Heese (Graduate School of Biomedical Science and Engineering) via video call in Skype. Heese conducts his lectures likewise. Live broadcast video lectures by Professor Klaus Heese Klaus Heese (Graduate School of Biomedical Science and Engineering) is currently teaching Comparative Biology for undergraduate students at Hanyang University. He also teaches multiple courses in the graduate program, including Selective Lab-work, Biochemistry Laboratory, Current Topics in Neuro-Immunology, Biomedical Tissue Engineering, and Current Topics in Genetics. Currently, he teaches these subjects through live broadcast video lectures. When asked if there were any difference he had felt between teaching online and offline, he said that he generally felt no difference. He found the Blackboard system convenient and efficient for uploading textbooks and homework, which was also what he always did for his normal courses. Moreover, since he holds his classes live, there was no tangible difference in interacting with his students. Nevertheless, there were minor inconveniences while holding a live session when he was logged out of the website without notice. Because there was no sign on the screen that indicated whether he was logged in, he realized many moments later that his screen showed nothing. In addition, he said the live sessions are extremely inconvenient for foreign students. Since most international student have been staying in their homeland, the time difference often results in their having to watch the lecture during the nighttime or early morning. However, he maintained that other than that, he has been generally satisfied with the system. In addition, he said he is trying to respond to the current problems by uploading the recorded version of the class on Blackboard, and advised students to make use of the videos. "Student will be able to use them to revise or make up for missed class materials," said Heese. Comparative Biology class conducted live through the blackboard system. Youtube live stream lectures by Professor Hong Ilhan Hong Ilhan (Graduate School of International Cultures) teaches an elective course, the World of Global Entertainment and Reading Trends. His chosen medium is Youtube’s live streaming. Unlike Professor Klaus Heese, Hong said that he feels a huge difference between teaching online and offline, even saying “They do share the same class title but fundamentally, they are different in every way.” Hong admitted that not having to go to school itself was a big convenience for him. However, there were many downsides to the system as he had to learn many online technologies in a very short time and also had to fix the curriculum he had already prepared in order to suit the system. Preparing the equipment was also difficult for him, too. More than anything, not being able to interact with the students as much is what he is most dissatisfied with. In order to overcome the inconveniences caused by the online lecturing system, Hong went over the reviews of the past online lecturing videos. He is also trying out different equipment to improve the audio and screen quality and uses a separate tablet to write on the textbook to replace the whiteboard. Another problem was interaction within classrooms. “Not every student owns a camera and microphone, so we use Youtube’s "raising hand" and chatting options to interact with each other, which has solved the problem.” Hong added that a change in mindset is the key. “I try to hold the lecture session with the mindset of –rather than a professor- a Youtuber or a radio DJ. It’s not easy but I am trying.” He thanked his students for patiently understanding the situation and keeping up with their work diligently despite the inconvenience. “I really wish to meet them as soon as possible in the classroom,” said Hong.

[Special]Hanyang's Dataset Can Predict the Coronavirus

As the coronavirus became a global epidemic, a Hanyang student developed a coronavirus dataset to help predict the spread of coronavirus. The dataset, named Data Science 4 COVID19 (DS4C), contains conveniently reprocessed data about the spread of the disease and is currently being shared with the world’s data scientists, conveying a message of willingness to work together in the face of this pandemic. DS4C is a structured dataset which offers reprocessed data about the coronavirus spread for easy analysis. It analyzes and visualizes the information provided by Korea Centers for Disease Control and Prevention (KCDC) and local governments. Kim Ji-hoo (Department of Computer Science, Master’s program), the project manager, explained that the aim of the dataset is to provide data in a more comprehensible format, ultimately to find meaningful patterns that can help predict the disease. The coronavirus dataset, Data Science 4 COVID19 (DS4C), developed by Kim Ji-hoo (Department of Computer Science, Master’s program). The dataset is shared on Kaggle for the world's researchers. (Photo courtesy of Kim) Kim started the project because despite the seriousness of the virus and his willingness to help the situation by using the data, information available was very complicated to digest. So, he developed his own coronavirus dataset as a tool for any further data analysis. The dataset organizes detailed information including patient information; patient routes traveled; Seoul’s floating population; time series data based on age, gender, and province weather; and more. This categorized information can perform various tasks, such as help predict the changes in the number of confirmed cases, visualize the data into a more legible format, and analyze the connections between the confirmed cases. The English version of the dataset is currently available on Kaggle, an online community of data scientists from around the world, in order to help other data experts who are working on similar tasks. It has become hugely popular, quoted and referred to by many scientists around the world. "A developer in France even called me to personally thank me for sharing my dataset,” said Kim. Thanks to his contribution, he received a gold medal on Kaggle as the most referenced project, making him the first Korean recipient of this honor. Kim was the first Korean to win a gold medal on Kaggle for developing the most referenced project. (Photo courtesy of Kim) Kim expressed his gratitude towards his colleagues who worked together on the project. “It helped me in many ways because their feedback allowed me to discover methods that I could never have thought of alone,” he said. Kim also said he is proud that his work contributed in making the data flow, reprocess, and reach other researchers and encouraged his fellow Hanyangians to help overcome the pandemic in their own individual fields.
