[Student]Thinking Outside the Circle

Creative ideas can originate from literally everything, depending on the creator’s attitude. When making an advertisement, inspiration can come from other advertisements, one’s experience or thoughts, or other people. For Kim Dong-hoon (Department of Educational Technology, 4th year), the winner of New York Festivals 2017, however, it comes from his dissatisfaction about the society. New York Festivals is one of the most well-known international award competitions for the world’s best works. Winning two Third Prizes in the New York Festivals 2017, Kim has taken a step closer to his dream. Different perspective, different approach Kim’s works by the name of ‘Cover by Artist’ and ‘Missing Models’ each received a Third Prize in the competition. ‘Cover by Artist’ is an advertisement idea proposed to the most popular digital music service in the United States Spotify, which puts the stage performance video of an artist on the space on the screen where there originally lies the cover album of the music to further promote the artist’s work. “If you use a music streaming service, the cover album takes up most of the space of your screen. I personally enjoy listening to live concert music and I suddenly thought if I could turn the idle space into a room for performance videos, this could be a means of advertising while making the service more enjoyable.” Spotify - Cover By Artists from Donghoon Lee on Vimeo. His other work ‘Missing Models’ is an idea derived from the hopes of helping to find missing children. In a poster, there are hundreds of faces of missing children clustered together. That makes it hard for people to take a close look at each one, which got Kim thinking. Kim thought about instances where people take a close look at the figure and came up with home shopping. He applied the concept to WooCommerce, a customizable e-commerce platform for building online business and inserted the missing children’s face as the models’ face in the home shopping sites. In this way, the faces of the children could be better recognized. Woocommerce - Missing Models from Donghoon Lee on Vimeo. Spotify, Woocommerce, missing children, and home shopping are all something that everyone is familiar with. Yet, no one has ever came up with these ideas so far. Kim’s way of thinking and approaching certain situations led him to devise such ideas. “I take a lot of notes in my daily life. It could be under any circumstances, really. Those little notes help me to create helpful ideas later on.” From problem to idea “When I look at advertisements, there are a lot of things that I don’t like about. In general, I see a lot of factors in this society that could be improved. What I do in that situation is that I take note of them and try to solve them in my own way, through making creative advertisements.” This is how his two award winning advertisement ideas came into being. Kim sees every problem as a potential idea for his work and use them as a source of ideas. “I don’t have a particular source of inspiration every time I make an advertisement. My daily life and every aspect of it could be my inspiration that gives me ideas.” Kim wants to make advertisements that could help solve social problems. Kim first got interested in making advertisements after watching one in one of his classes. “It was a chocolate advertisement and it was the first time in my life that I felt like I wanted chocolate just by watching an advertisement. I was amazed by how a short advertisement could convince people to change their minds.” As an Educational Technology major, Kim knows how to think from a learner’s perspective. This helped him to consider what the audience would want from an advertisement, enabling him to produce a more effective result. After making ads, being aware that random moments could inspire him, Kim became more attentive to little details of his life. "My next goal is to win next year's Cannes Lions, which is another prestigious international competition." Jeon Chae-yun chaeyun111@hanyang.ac.kr Photos by Kim Youn-soo

[Faculty]Speech Privacy in High-Speed Train Cabins

Professor Jeon Jin-yong of the Department of Architectural Engineering is an expert in the field of architectural acoustics. His paper, “Control of interior surface materials for speech privacy in high-speed train cabins,” discusses a novel method of using the sound masking technique along with the interior sound dynamics inside the train itself. At times, Speech Transmission Index (STI) is required in Europe and North America for announcements made in trains. During the period of 2012-15, with the support of Korea Agency for Infrastructure Technology Advancement (KAIA), Jeon had the opportunity to create architectural sound design for trains. Jeon is explaining about the importance of speech privacy. Jeon has experienced a serious problem about five years ago while riding a KTX train and had a chance to hear the ladies talking at the back about seven rows away from him. All the speeches being made by the ladies were being bounced on the shelves of the KTX and reached the other passengers which meant that everyone was listening to their conversation. After the experience, Jeon has decided to set up a new guideline on high speed trains for speech privacy between people. There are also surveys that point out that the most annoying noise on KTX users being the conversation between people by 31.8%. It is suggested by Jeon that the back of the chairs should be high and there should be the minimum space between the chairs in order to block out the conversation from being overheard. Since sound travels through the air and bounces from walls to ceilings, less space being provided for it to move around freely is a way to retain speech privacy. In addition, the material for chairs, ceilings, and side walls being high sound absorption material is suggested to reduce the interior noise. There is yet to be studies made on its fire resistance performance evaluation, weight lightening, and maintenance. Using sound tracking devices, Jeon was able to redesign the interior of the KTX. (Photo courtesy of Jeon) Sound masking has been one of the solutions as to provide speech privacy. It is the beating, squeaking and rattling noises that are created outside the train being intentionally flow into the train to cover up the conversation between people at about 50 to 60 dB. Speed trains with no interior noise has the features that allows the sound of human voice to travel through the space such as low ceiling, long space, and narrow walls. However, sound masking does not suggest interior noise to be too high since it would make the passengers dissatisfied. It means that there has to be enough interior noise in order to secure the speech privacy. Through Jeon’s studies made with computer programs and 1:10 scale sized KTX models, it is now suggested that high speed trains being produced nowadays provide enough speech privacy. After having contributed to the society through his novel findings, Jeon wishes to continue with the studies even further to solve the problem of noise complaint issues between neighbors through deep learning programs. Jeon wishes to contribute to the society through his sound interior designs. Kim Seung-jun nzdave94@hanyang.ac.kr Photos by Kim Youn-soo

[Academics]Ground Breaking Advancement in Medical Magnetic Robot

The era of robots wandering inside a human body for medical treatments is about to face our generation. Though the research is still in the process of developing magnetic fields and improving robots, the actual application of the medical robots is expected to occur in a decade. In his research “Magnetic Navigation System Utilizing Resonant Effect to Enhance Magnetic Field Applied to Magnetic Robots,” professor Jang Gun-hee of the Department of Mechanical Engineering proposes the improvement of the magnetic navigation system (MNS) via RLC (stands for resistor, inductor, and capacitor) circuit in the hope of its medical application. Generation of strong magnetic fields in high frequency When doctors treat for blood vessels related illness like coronary artery diseases or have to execute endoscopic surgeries, they often use catheters (thin tube made from medical grade materials) controlled by their hands and medical, empirical sensations. However, these catheters don’t have the sufficient controllability for the physicians due to their long, flexible wires. “The main point of this research was to minimize the surgical errors that these catheters may incur. So, we decided to make magnetic robots that are microscopic enough to wander inside our vessels,” said Jang. The types of robots currently in technical development are various- fish type robots, wobby-like robots, swimming robots, helical robots, and more. However, the magnetic robots especially intrigue the academia. “Compressed springs inside the robot will spread out, enhancing its drilling capability inside the vessels, which its movements will be guided by the magnetic system. Improvements in this MNS are significantly vital, as every mechanical motion of the magnetic robots is proportional to the external magnetic field,” emphasized Jang. Jang has been working on the magnetic navigation system research for about 12 years, which currently resulted in the torque magnetic field on the right. Through the experiments to unclog the blocked area of tubular environments, Jang and his students researched on a novel MNS with the resonant effect of the RLC circuit. “Simply saying, these robots with the MNS have magnets. When the north pole of the magnet approaches another north pole, it will push, and vice versa in the case of the south pole. This is the simplistic picture of how the magnetic robots and the MNS are working,” said Jang. Advancement to this fundamental phenomenon, Jang refers to the "closed right hand rule" (Ampere Law that relates the net magnetic field along a closed loop to the electric current passing through the loop) to explain his research. “In our newly developed MNS, inside the diameter of 50 centimeters wide spherical environment, we can create and control strong magnetic field in any direction which eventually generates useful various mechanical motions of the magnetic robots,” highlighted Jang. Another unconventional discovery of Jang’s research is the application of resonant frequency in the RLC circuit to amplify the magnetic field of the robot. RLC stands for resistance, inductance, and capacitance which all are in the influential relationships in science. When the alternating voltage is increased, the resistance should be divided to flow the current. However, as the alternating frequency of voltage increases, the current decreases due to the inductance of the coil. “We eliminate the effect of inductance with the application of varying capacitance that leads to maximizing the current and the magnetic field in high frequency,” explained Jang. This phenomenon was able to generate fast drilling motion of the magnetic robot to unclog the blocked area of blood vessels. Furthermore, application of the MNS developed a crawling robot that can also deliver drugs into a human body, which Hanyang University gained its international patent of. (Video courtesy of Jang) Hopes for the scientific improvement It has been a decade since Jang has been working on this magnetic robot research. The beginning of all dates back to when his mother was hospitalized due to her coronary artery disease in the heart. “The doctor told me that the illness is genetic and I may also be in danger. So, I thought that rather than believing in the doctor’s hand and the catheter, I should believe in science to develop this surgical methodology and first test on me,” said Jang. During the several years that Jang has been working with his students, he also began to long for fostering his students and their success. “I was always interested in the concept of a motor since I was young. This academic desire eventually led me to become a scholar, but since I became a professor of many students and a father of two daughters, I began to be intrigued to their life-long academic achievements,” reminisced Jang. Ph.D students of the Department of Mechanical Engineering- Lee Won-seo (left) and Nam Jae-kwang (right), also participated in the research with their professor Jang. It is estimated that after more technical amendments of this mechanical robot, it will be capable of testing on animals, and then applied to human surgeries, which will take about a decade. During this journey to scientific achievements, Jang realized that efforts are what science really value. “Just like my students who endeavored all their desires to science to leap higher, I hope that the South Korean scientific academia will also hope for the brighter future,” reminded Jang.

[Alumni]A Shining Star in Operas and Musicals

A Verdi opera ‘Rigoletto’ came to an end on the 30th of June with loud applause from the audience. A renowned vocalist, Kim Soon-yeong (Department of Vocal Music, ’06), famous for both musicals and operas, caught the attention through the character named ‘Gilda’. She acted out the pure and innocent girl through her voice, leading the opera to a great hit. A soprano, stepping into a musical Opera vocal performers would frequently think that they would not be able to perform again in operas once they expand thier activities to musicals. However, Kim completely broke the stereotype through the character ‘Christine’ in the musical ‘Phantom’, which was premiered in 2015. She was casted by EMK music company through the music video ‘First Love’, composed by Kim Hyo-geun (Click to listen). “A lot of acquaintances tried to persuade me not to do it since they thought I wouldn’t be able to perform again in operas. But I didn’t want to miss an opportunity of new experiences," said Kim. Kim explaining her opportunity of starting musicals Of course, Kim was not a perfect actress from the beginning. She faced extreme hardships as she had to step into an entirely different area. The tempo of the musical was much faster than that of operas along with the increased number of acting scenes. “I wasn’t able to keep up with the other actors at first. The choir even ridiculed me during the practices. However, as I got better through persistent practice, the pure, passionate character of Christine became soundly mine and I gained more confidence.” Kim reminisced. She also mentioned that she was able to understand the character more deeply because of the fact that Christine came from the countryside, just like Kim who moved from Daejeon to Seoul to achieve her dream. As a result, Kim attained absolute success and became the only actress who took the role of Christine again in the second presentation of ‘Phantom’ this year. She remarked that she was able to act in a much more relaxed manner throughout the second presentation as she was extremely tensed up in the first one. Kim praised the features of musicals through her own experience. “I was never bored of acting even though I played the role of Christine numerous times. It felt new everytime with different actors of ‘Phantom’. They allowed me to feel different emotions each time I act on stage.” Kim performed as Christine 98 times in total, but she is confident that she enjoyed each and every performance. A scene of the musical 'Phantom'. The phantom of the opera 'Eric' is teaching songs to 'Christine' in the picture. (Photo courtesy of Kim) Kim’s significance of operas and musicals “I would never be able to choose between operas and musicals. They both have their own charming points.” said Kim. Formally, even when both performances practice for the same amount of time, operas usually have only 2 or 3 plays while musicals have much more plays; 50 for each presentation in the case of ‘Phantom’. Therefore, Kim pointed out that she can fully absorb the character of musicals throughout the acts but only feels like rehearsals with operas. Kim also pointed out the different focuses of each plays. Operas focus more deeply into music, while musicals put their priorities on acting. Therefore, Kim puts every ounce of her energy into her songs in operas. She explained that she can reach a state of catharsis through the concentration of her voice in the music. On the other hand, as musicals focus more in actions, Kim felt that they tend to be more energetic, diverse and colorful. Kim praised both areas for their own unique traits. "No one told me to sing. I just loved singing so much I searched for chances to sing." Kim anticipated that she would continue performing in both areas of operas and musicals. Her aspiration is later to be referred an all-rounder. “I’m not the best in any area. However, I think that’s the very reason I was able to try both of them, and make satisfying results.” Kim wished that she could inspire more of her junior colleagues to broaden their views and to challenge themselves in various areas. “Performances nowadays show a collaboration of various areas. Fitting to the trend, I wish opera vocal performers can also show active performances in areas other than just from their own.” Kim concluded.

[Special]From Fashionable to Affordable

Ubiquitous, affordable, and trendy are the most suitable terms to describe Korean beauty shops and their products. It is no secret that Korea is outrunning its competitors in the global beauty market, with both its domestic and global popularity skyrocketing as new products are introduced by various brands. The so-called “road-shops” in Korea (because they are on roads) are easily found in the country. From numerous brands, road-shops are stocked with beauty items that are reasonably priced. From being accessible to affordable, K-beauty brands are seeing continuous growth in their sales in the global market. Brands and trends Famous Korean mid-range beauty brands. (Photo courtesy of wevio.com) Etude House, Tonymoly, Innisfree, Missha, The Face Shop, Nature Republic, Skin Food, and Holika Holika are all famous and popular cosmetic brands in Korea. Each brand boasts its own series of beauty products, loved not just for the products themselves but because of their eye-catching, likeable packaging. Korean beauty brands have also gained recognition for their innovative formulas, ingredients, and manufacturing processes. On top of all these, the sophisticated and demanding customers in the local Korean market have also been one of the major drivers. The facets aforementioned push K-beauty brands way ahead of the game, differentiating them from other international beauty brands and even in the highly competitive beauty market. The short product development cycle compared with the international players helps Korean beauty brands respond more quickly to evolving customer demands and trends. Innovation in product development is driven in part by the heavy investment in research and development. Mid-range beauty brands also has an impact on its domestic aspect. Since it is very accessible and affordable, young students, ranging from elementary to high school students can also be the tarketed customers. This has lowered an entry barrier to cosmetics, teenagers showing scorching interest in makeup products and makeup trend. The outcome was the so-called “student makeup” which is basically makeup style worn by teenage students. Examples of unique packaging of K-beauty products. (Photo courtesy of pinterest.com) Shop to shop, country to country Even though there are an increasing number of Korean beauty brand shops abroad, an influx of tourists is visiting Korea with the main interest of shopping for beauty products. Myeongdong and Ewha Woman’s University shopping street are the two most famous places to shop for cosmetic products, since virtually all brands of beauty stores are lining up in the street.

[Student]Winners of 2017 Robofest Vision Centric Challenge

Robofest is a renowned robot competition that has started from 2000. Hosted by Lawrence Technological University in the United States, over 20,000 people have competed from 14 different countries in the last 17 years. Bae Jong-hak and Yoo Ho-yeon (Robot Engineering, 3rd year) have worked together as a team in 2017 Robofest that was held from June 1st to 3rd in Florida, and won the Vision Centric Challenge. Back to back winners Team Linker, consisted of Bae and Yoo have won the 2016 Robofest last year as well. It is the same competition with different rules. “They host the competition in the U.S. in June, while in Korea, it is held in October,” explained Bae. This time, Bae had the full support from the Department of Robot Engineering. “Our department has generously provided us with the opportunity to travel to the U.S. for free and also helped us out with the materials needed to create the robots as well. Special thanks to professor Han Jae-kwon for helping us out with the robots,” added Bae. Yoo (with the robot), Han (middle), and Bae (with the trophy) are smiling in front of the camera. Team Linker has received such a good feedback thanks to the internal software of their robot. The objective of the competition was the robot to perceive the numbers and equations through the camera and eventually reach a certain result out of it. “We put a lot of effort on the software so that when the robot gets stuck with the equations, it could move back a little instead of standing there still,” said Bae. He explained that Team Linker has prepared for the competition for 3 months and it took about one month to create the robot. “ Software of the robot took longer for us because it was more important than the hardware.” "It has been a privilege for us to participate in the competition." I – Robot After studying one more year to retake the college entrance examination, Bae found his interests in creating robots. “One of my childhood dream was to create a robot on my own,” recalled Bae. He explained that Department of Robot Engineering would be a perfect fit for those not interested in particular field of study. Since robotics requires knowledge from diverse fields, students are able to acquire engineering skills that could be applied in any type of studies. “We learn about diverse types of integrated studies and then move on focus on a certain field that catches your attention. For me, it was image recognition. I gained more interest after studying it during the competition,” said Bae. Bae wishes to create robots similar to Jarvis. In the future, Bae wishes to study more about the robots and image recognition in graduate school. “I see a lot of possibilities from the robots in that we could have a better future with them,” commented Bae. He wishes to create a home robot that would be able to handle useful tasks like Jarvis from Iron man. Bright future seems to lie in front of the winners of Robofest Vision Centric Challenge.

[Event][Hanyang Festival 2017] Eat, Drink, and Enjoy!

The once desiccating sun is setting and cool evening breeze is blowing. Smells of barbeque is flowing and lights of booths are turning. People are busying themselves here and there in preparation for the outdoor pubs and game activities. With games and activities during the day and pubs and performances during the night, the festival seems exciting and lively. Daytime Animation During the day, games and amusement activities were set up in every corner of Hanmadang (Han Yard). By the name of High Five with the Booths, the planning committee this year has prepared five booths of funs and activities: escape-the-room game, hair chalk booth, Hanyang Land, eat-alone-competition, and Alohanyang. Among the five, the most popular booth seemed to be the escape-the-room game, as far more than expected students visited the booth and protracted the activity for a day longer. Hair chalk booth was big hit, too, as many people were interested in coloring their hair free from damage and permanency. In Hanyang Land, there were a mini Viking ride, punch-machine, and bubble wrestling. Mission: escape the room by solving the puzzles with given clues in the room! Question: who is the murderer? Screams of students echoed the nearby area of the viking ride. Males and females, both were dying their hair with chalk of their favorite colors. Bubble wrestling! Don't tumble down before your enemy! Students from Alohanyang campaigning for fine language throughout the festival. Other booths set up by various clubs also offered games and activities along the track. Table tennis, archery, face painting, and baseball were situated in corners of the pathway. Intense exchanges of the ball went on at the table tennis booth. The master of archery teaching a participating student how to aim the bull’s eye. Friends drawing on each other’s face at the face painting booth. Baseball booth enjoyed batting and pitching. Random survey: vote with your trash, which one do you prefer? Nighttime Festivity During the night, outdoor pubs and kiosks of barbeque and cocktail were attracting lines and lines of students. The smell of barbeque sticks and the music of outdoor pubs seemed spirited and youthful, as everyone was eating, drinking, talking, singing, and socializing as a big group. Going a little uphill toward the outdoor theater, swarm of people were gathered around the stage, as they longed to see a famous idol group Girlfriend. Cheers and shouts for their desired celebrity was well heard across the area and the performance even invigorated the crowd louder and stronger. Grilled chicken stick is being ready to be served. "If you win me with rock-sissor-paper, I will give you a glow-in-the-dark bracelet for free!" The outdoor pub is bustling with students hanging out with their friends. A cocktail kiosk selling various kinds of drinks. Students in charge of preparing food at the outdoor pub is busy with their duties. Girls group Girlfriend on the stage of the outdoor theater. Everyone is eager to see the celebrity closer, busy taking pictures and filming the performance. The end of the performance! Everyone have a safe and enjoyable night!

[Student]Experiences at Hanyang, Francesca's story

Francesca Barbieri, the student from Humanitas University, the private university at Italy dedicated to the medical sciences, participated Hanyang summer program for her medical training. She shared her remarkable experiences and memories here at Hanyang University. Prescription For Growing: Learn Skills But Especially Make Friends I would have never imagined to realize such a big project in such a short time. I found myself on the other side of the world just after a few months I started thinking about it. As I knew about the possibility of obtaining a travel grant, I applied and was then accepted by the cardiology Professor Kyung -Soo KIM. Humanitas therefore gave me the opportunity to spend more than 40 days at the Hanyang University Medical Centre, in Seoul. There, I attended the cardiology wards, outpatient visits and the cardiology research laboratory. To tell the truth, the difficulties of such an experience can be many and discouraging. But everything becomes so pleasant and worthy when you meet the right group of people. Professor Kim and his group of physicians, residents, laboratory members and students accepted me as if I had always been one of them. My family and friends were definitely far away, but I found myself in an environment in which I never felt alone, I could ask anything I needed and was given all the possible help. Trying to follow them during the working day was though, with no doubt. I used to spend between 12 and 13 hours per day in the hospital, some in the clinic, some in the laboratories. As a second year student, I felt to have a solid theoretical knowledge but it was the first time for me to approach the practical clinical environment or research designs and laboratory protocols. I arrived as a very worried student, concerned about what to expect. I came out after 40 days with a basic knowledge of the main heart diseases, how to use the laboratory equipment, how to follow an experimental research design. This was achieved thanks to the constant, careful and personal tutoring I was provided, I always had at least one physician or one researcher on my side. I came out as part of a group of friends, and this was the most surprising and precious aspect. The attention they paid to the success and profit of my experience was invaluable. As invaluable is what I have learnt. Sometimes it is unbelievable how much we can grow in such a short time. * Original article at Hunimed.edu (link)
