[Academics]Creating the Most Stable Elevators

Like any other industries, the field of engineering is a harshly competitive market. Stepping ahead requires the latest technology, practical design, efficient utilization, and the list goes on. In the area of elevators, it is no longer just about going up and down. It is not even the speed of the transport. Rather, it is about how smooth the ride is. In this regard, Professor Hong Jung-pyo of the Department of Automotive Engineering has paved the way for elevator manufacturers to produce the most stable elevators in his paper, “Advanced method of selecting number of poles and slots for low-frequency vibration reduction of traction motor for elevator.” Professor Hong’s research began with the approach of a prominent elevator manufacturer, requesting a joint research to seek solutions for some of the stability issues that they have had with their elevators. It happened to be a great opportunity, as the number of domestic test towers for elevators were quite limited, and using them required cooperation with a company that owned such a facility. A blueprint of an elevator motor (courtesy of Montanari Elevators) The biggest concern for elevator manufacturers had always been vibration. Specifically, it is the low-frequency vibration that humans are especially sensitive to, which is caused by the generation of power from the motor. As most people know, elevators move through the winding and unwinding of ropes that are connected to a motor. The level of vibration felt in the car box, or the compartment that people actually get on, is determined by the motor. To put in simple terms, the design of the motor decides how shaky the elevator is. Just as the riding comfort decides the price of a luxurious car model, the reputation of an elevator brand is determined by its stability. Hong’s research aimed to analyze the causes of vibration and provide solutions to minimize it. Hong’s research can be conceptualized by understanding a fundamental mechanism of the motor: the poles and slots. Poles refer to magnetic poles, equivalent to the north and south poles from a general conception of magnets. Slots are physical holes in the motor where conductors are placed to allow electrical current to flow. Upon the flow of electricity, the poles and slots create an electromagnetic force that rotates the motor and provides physical power. The combination of the numbers of poles and slots in the motor results in weaknesses in particular areas that cause instability and, thus, vibration. Hong used a mathematical approach to diagnose the problem with various motor models and provided the ideal number of poles and slots to minimize vibration. Professor Hong with his co-author, Kim Doo-Young Hong expressed deep interest in extending his research into similar areas. Like any other field of study, the engineering field is also becoming interdisciplinary. As can be seen in Hong’s study, the research process involved a combination of electrical engineering and mechanical engineering approaches to the motor. The field of electrical engineering and mechanical engineering are now somewhat well-established individually. In contrast, we have little data and research on what happens when they interact with each other. The necessity for research into this field of electro-mechanical engineering has always been demanded, yet barely explored. Hong aims to study the designs and mechanisms of various systems extensively in his further research. As a word of advice to students of Hanyang, Hong commented that hard work is the only thing he can emphasize. As a respected professor, many students come to him for counseling on issues such as pursuit in a field of study, seeking career paths, and various decisions in between. Rather than spending time deliberating, he advises students to find any reason to make a decision. “It’s not about where you end up, it’s about how hard you work after you get there.” He also stressed constant self-development, adding that improving yourself by the smallest bit from one day to another will make you a different person by the end of a year.

[Event]Crisis of Humanities? Importance of Humanities! (1)

Professor Yoo Jae-eun of the Department of English Language and Literature gave a lecture titled, “Welcome to the desert of the Real” in the College of Humanities on the 13th. This phrase, better known as a famous line of ‘Matrix’ (1999), is a book’s title written by Slavoj Zizek. She gave a lecture based on this book, explaining the influence made on the world after the 9/11 terror in America along with her philosophical opinions and interpretations. ‘The Real’ society Yoo first gave an explanation on ‘the Real’, meaning ‘existence’, differentiating the word with ‘the real’, implying to the general reality, through the capital letter. Lancan, a psychoanalyst, theorized the field of ‘the Real’. He divided the process of human consciousness’ development into three steps: the Imaginary world, the Symbolic world and the Real world. She started off with this background knowledge in order to refer this to diagnose the current post-modern society after the 9/11 terror, which was her main theme of the lecture. Yoo giving a lecture of 'the Real' She explained that it was proven that we have stepped into ‘the Real’ society through America, the powerful nation, being attacked. The notion of ‘the Real’ refers to incidents we experience but cannot fully understand, such as death. As people’s consciousness and the society’s trend completely changed after the 9/11 terror, the sentence, ‘Welcome to the desert of the Real’ was made. Yoo gave personal experiences she faced after the terror, as she was in America for her Ph.D. Professor Yoo is currently studying these conditions of a post-modern society. Yoo commented, “I chose this title as it is an eye-catching and a famous phrase. I intended to discuss the changed world order after the 9/11 terror as a citizen of the Third World." A student also gave positive comments on this forum. Park Young-in, a graduate of Hanyang University and now a student of the graduate school, commented, “It was a special lecture for me as I became a great fan of her through her past lectures. I am also interested in this subject, so I appreciate that the lecture provided concise explanation on the topic." Park giving her opinions on the lecture Future humanities forums This lecture of professor Yoo was a part of a program currently proceeding in Hanyang University in the name of ‘Future Humanities Forums’. This was the 11th forum, and these forums are held every month by the core enterprise organization in the College of Humanities. A total of 16 schools were selected for this program and will be supported with 40 billion dollars for three years. This program was made as one of the alternative methods to resolve the avoidance of humanities. The College of Humanities made three courses: international studies, merged majors, and intensification of foundation studies. This program works as the training of future-oriented and integrated students and therefore gives forums on these three subjects in rotation, allowing everyone to easily approach humanities. The Future Humanities forum has now already finished its 11th lecture, starting from the second semester of last year. The themes, depending on the lecturers, are diversified starting from arts and science to artificial intelligence. They, therefore, emphasize interdisciplinary approaches but talk about general humanistic worries at the same time. A researcher of the Division of Applied Humanities, Park min-a mentioned, “Hanyang University is working hard to plan various integrated humanities programs and is, therefore, trying to form mutual exchanges of lectures with different schools.” "More people should be interested in humanities!" The forums focus on various discussions on the direction of future humanities, as well as the critical feedback on the current role of humanities. The Division of Applied Humanities are enthusiastically working on various methods to make humanities a field that can be approached more easily. These forums take place once every month in the afternoon of a Friday. Next month, the director of Bosch Korea is planning to give a lecture. “I hope a lot more students would be able to have interest in humanities,” wished Park. On Jung-yun Photos by Kim Youn-soo

[Event]When Altogether, You Are Never Alone

When the season comes for farmers to harvest crops and fruits treasured with their sweat, it is the best time to throw a party. Koreans named this day of invaluable delight, Chuseok- Korean Thanksgiving that comes every August 15th of the lunar calendar. While Chuseok presents Koreans with blissful moments to enjoy traditions, a large number of international students often get lost on what privileges this day delivers to them. In order to help the international students learn more about Chuseok and how to enjoy it, the Division of Engineering and the Office of International Affairs (OIA) prepared discrete Chuseok festivals. Berk Gebes (English Language Education, 2nd year, left) and Shalom Oruma (Division of International Studies, 1st year, right) are trying on a hanbok. On the right, caligraphy is done by one global student who says, "Big things begin small." Invitation from the Division of Engineering The Division of Engineering invited all of the international engineering students studying at Hanyang University (HYU) to experience and learn more about Chuseok. The event was held on September 26, 2017 in front of the Engineering Building and lasted for a 150 minutes, beginning at 12 PM. In order to provide a unique experience for foreign students who can’t easily access special Korean culture, the Division of Engineering included a total five booths for the Chuseok adventure. The first booth was a traditional food festival, including songpyeon (half-moon shaped rice cake served only during Chuseok) and sikhye (sweet rice drink). Also, a booth for trying out Korean traditional clothes- the hanbok was prepared. Students received the opportunity to learn about the various colors and shapes of the hanbok. The next expedition was a traditional folk game. The most interesting game that intrigued the students’ attention was a slap-match game, also called ttakji. The runner-up of this match was Hafiz Omer (Electronic Engineering, 2nd year) from Malaysia, who recalled this game as the best experience in this event, saying, “it was a great experience for me since we don’t have such a game in Malaysia. Also, trying on the Hanbok made me feel like a king due to its silky texture and vivid red color.” The Dance Club of the Division of Engineering "Bunpuri" is performing samulnori (left), and international students are enjoying traditional Chuseok food (right). The program also included a booth for making Korean traditional masks and folk-painting bags. This program introduced a new concept of Korean masks and folk-painting and allowed foreign students to easily experience the culture in a more exciting way. Along with various programs, the samulnori performance (Korean traditional percussion quartet) was also displayed by the Dance Club from the Division of Engineering- Bunpuri. “I love Korean culture, and the samulnori performance was also fascinating. I am especially impressed by Arirang, the Korean traditional song,” said Dilmac (Department of Computer Science, 3rd year) from Turkey. Complete all the Chuseok quests and win the prize The OIA has been preparing Chuseok events for international students of HYU every year. This program took place at the entrance of the International Building on September 27, 2017. “The purpose of this program is to let the foreign students spend the long Chuseok holidays together since most of them are here in Korea alone,” said Yang Ji-young, event supervisor of the OIA. Along with members of the OIA, Global Saranghandae (international HYU ambassador) and Welcome Handae (volunteer group for international students) members also helped global students learn and be more adjusted to Chuseok culture. The program consisted of trying on hanboks, writing words of Chuseok wisdom in individual’s calligraphy style, folk games, and a traditional food booth. Once individuals were confirmed to have completed all the activities, the OIA gifted them with traditional presents. Global students passing by the International Building could try on a colorful hanbok with a cup of sikhye in their hands, and songpyeon in their mouth. “I think the hanbok looks good on me, due its beautiful colors. I had to study for this year’s Chuseok holiday, but this event gifted me a great memory to dwell upon,” said Berk Gebes (English Education, 2nd year) from Turkey. International students are playing folk games - jegichagi (left) and tuho (right). Also, folk games such as tuho (traditional game of throwing sticks into canisters) and jegichagi (Korean shuttlecock game) drew the attention of foreign students. The calligraphy corner, where international students could experience writing well-wishing remarks for each other on picture scrolls, was also crowded. “I especially loved tuho, despite the fact that I missed out all the marks! Even though I miss my family in Nigeria, staying here with my friends during Chuseok through this kind of event definitely cheered me up,” said Shalom Oruma (Division of International Studies, 1st year).

[Academics][Researcher of the Month] Producing Energy Through a Single Thread

'Lack of energy’ is an issue the whole world is focusing on. Various countries are searching for effective renewable energy and new materials that could replace the current energy sources. Professor Kim Seon-jeong (Department of Biomedical Engineering) discovered a new material every researcher was looking for. Kim's paper, “Harvesting electrical energy from carbon nanotube yarn twist” introduces the world’s first new material, which can produce energy through slight movements. Kim explains the concept of his new material Professor Kim’s research team started its first project in 2006 on artificial muscle. However, after his research, Kim realized its limitations as they were only able to move through an external energy source. Therefore, he thought of a new idea that the muscle would be more effective when it is able to produce energy by itself. Carbon nanotube is a new material which is a type of conductor and has a diameter of only a few nanometers. This material was made as a thread in the artificial muscle. However, when these threads were finely twisted into one direction, they were able to produce energy by itself through its contraction and relaxation without an applied voltage. Being made into a spring, their length can be changed as much as 30 percent on average. This new material, named as ‘twistron harvester yarn’, allowed a chance for the muscle to move by itself without a separate power source. This twistron harvester yarn looks and acts as if it were an ordinary thread. This states that making clothes out of this material is possible. Once this comes into realization, this would give a boost in making wearable devices, as producing electricity without an energy source is possible. Moreover, this thread is possible to use inside water, giving another possibility of an effective alternative energy. This has already been tested in the East Sea of Korea. Kim’s research team made a model consisting of a glass bottle connected with an electrode, the thread, a balloon, and an equipment that could measure electricity. As the twistron harvester yarn contracted and relaxed, electrical energy was verified from the ocean. Kim showed great passion in the research he was conducting. This research on the twistron harvester yarn was his fourth research. He has been working on artificial muscles for the past nine years before he started this research. “I didn’t start this research solely to find the twistron harvester yarn. I felt the limitations within the research I conducted earlier and was seeking for development,” reminisced Kim. He explained that he wasn’t the only person who conducted the research. Eight teams from three different countries worked on this new material for two years to deduct a better result. “We had a meeting through Skype every week, along with frequent visits to each team. Everyone had great passion and interest towards this research, and I believe that shows the firmness of this research,” said Kim. "Reach towards your own interest!" Kim also emphasized the attitudes Hanyangians should have towards their life. Even though he mainly teaches graduate school students, he wished all students could find what they truly wish to do. “Find something unique of your own. Find something you enjoy, and then you will be able to continue on with whatever you are doing. There are countless routes for all students. I wish students would keep challenging themselves to make the greatest results of their own,” wished Kim. Just as his words, Kim will continue with his work with great passion, for even better convenience for global citizens. On Jung-yun Photos by Kim Youn-soo

[Academics]Low Energy Consuming Utilization of Chemical Sensors

When a chemical sensor is embedded into a mobile device, the significant sensing properties are amplified by low costs, high response, great stability, and robustness. However, there is one property of a chemical sensor that hinders technicians from utilizing it with a mobile device--unbearable power consumption. In his paper, “Self-heating effects on the toluene sensing of Pt-functionalized SnO2-ZnO core-shell nanowires,” professor Kim Hyeon-woo of the Division of Material Science and Engineering proposes a self-power sensor that allows low energy consumption of 31 μW at 5 V. Kim is explaining about the novel discovery of his research. In order to apply chemical sensors to mobile devices, the temperature of the sensor should be high enough to be generated. However, in the process of raising the temperature, the magnitude of energy consumption is vast. “Chemical sensors have extreme advantages such as cheap costs, small size, excellent stability, and robustness. However, the high energy consumption prevents scientists to consider them as an option for mobile devices,” said Kim. To reduce the energy consumption, Kim and his fellow researchers have exhibited a self-heated nanowire sensor through this study. “For the reduction of energy usage, we synthesized Pt nanoparticle-functionalized SnO2–ZnO core–shell nanowires. The shells of these wires utilized for the chemical sensor are thicker than usual. This allows a larger self-heating ability and a higher sensor response,” explained Kim. SnO2–ZnO is a synthesis of tin dioxide and zinc oxide that results in a strong core-shell (class of materials which have properties intermediate between those of small, individual molecules and those of bulk, crystalline semiconductors). The total energy required for this chemical sensor to be self-heated was 31 μW at 5 V. “This novel discovery was possible due to the groundbreaking nanowires that allowed the sensor to self-heat even at room temperature,” said Kim. Thus, this research, has ultimately suggested the potential application of chemical sensors into mobile devices, fully utilizing their peculiar sensing properties. “The sensor industry in South Korea will now be able to gain international competitiveness by exporting this novel sensor, which is currently in the process of development,” proposed Kim. Kim is holding a sensor that he's currently developing. The academic life of Kim has been devoted to nanostructure and sensors. His original research area was on nanostructure (a structure, especially a semiconductor device, that has dimensions of only a few nanometers). “I have always studied nanostructure, and I realized that the practical application of this leads to sensors,” explained Kim. Gas and radioactive sensors are Kim’s further research subjects, which he looks forward to utilizing in real life in a few years. “Pragmatic application of dramatic discoveries in research is difficult, but I will try my best to improve this industry,” revealed Kim.

[General]Enjoying Each Movement on Stage

The 2017 Korea International Modern Dance Competition successfully came to an end on the 12th, with 209 participants, recording the largest scale. Countless modern dancers showed wonderful movements on stage, heightening the tension. Out of these outstanding modern dancers, Kwon Jae-heon (Department of Dance, 4th year) proudly received the grand prize. We, therefore, met him again in a year, since his winning of the Dong-A Dance Competition last June. He showed more composure and maturity during his whole interview. Kwon showed his charming smile throughout the whole interview. Life of concours Kwon performed a stage named ‘Howling, Eighty Keyboards’ to Nocturn no.13, for this competition. A lot of the dancers make their own stages, and so did Kwon. He created a concept of himself being the 80 keyboards, so that he could show himself ‘being played.’ Kwon added that he continuously watched Cho Seong-jin’s performance videos to express the delicacy of his facial expressions. “I imagined myself as an actual piano. Therefore, there were hardly any emotional lines compared to last year’s stage,” explained Kwon. Kwon, just like any dancers, went through a long, tough time preparing solely for this stage. Even though his stage took place in September, he started his practices for his competition since January. It takes him a month to recover his basic skills and another month to select his music and to set a frame of his performance. Since March, he sets himself into practice for an audition in May held by the Department of Dance. After the audition, he practices for another three months until the competition. “There are professors during the audition who admonish sternly. I was hurt by some of the comments even though they gave me more motivation. The most memorable comment was that I had no possibility compared to my friend next to me.” Reminisced Kwon. A picture of Kwon on stage. (photo courtesy of Kwon.) This 2017 Korea International Modern Dance Competition was especially a meaningful competition to Kwon. Not only did he win an international competition, but he was also granted an exemption from the national military service. Korean male dancers are granted an exemption when they get first or second place in an international competition. To male dancers, two years of the military service is critical. The dancers’ body needs to be trained to be fit to dance well. However, after the compulsory military service, their bodies stiffen due to the lack of practice during their service. Moreover, the dancers need another two years to train their bodies back to their initial state. Therefore, Kwon was able to save four years of his career. When asked for his feeling towards his award, he replied, “I fell into tears as soon as I heard my name at that time. Currently, being able to not go to military service delights me the most. That two year gap is a big risk to dancers. I’m very relieved I don’t have to worry about it anymore.” As a dancer and a choreographer Kwon’s life of dancing started since he was an elementary school student. “I just liked the applause I received during the recreation time when I was only an elementary school student. I danced through searching and following various dancing videos on the internet, without any private lessons before I entered an arts high school,” explained Kwon. He, therefore, started in earnest since high school and prepared for Hanyang University while his friends prepared for university of arts. “I saw a performance by a teacher in Hanyang University and was truly captivated by it. It was hard studying when all my friends finished their examinations, but it was absolutely worth it,” reminisced Kwon. Now as a Hanyangian majoring in dance, he is preparing himself to be a choreographer beyond a dancer. His dream hasn't changed since last year. He, again, emphasized his goal throughout his interview. “You don’t have to dance well to become a choreographer. However, you need an extensive view to choreograph well.” Kwon explained that he, therefore, visits and enjoys a lot of museums and performances. He listens to a lot of classical music, especially Chopin. Moreover, as his brother majors in creative writing, Kwon showed extra thanks to his brother for his help. “I talk a lot about movies, arts, and music. He’s the very one who made the title for this competition. We tend to understand each other well since we have the same interests,” explained Kwon. "I want to be a choreographer!" Now, before his graduation, he is looking forward to his department’s performance. Hanyang University’s Department of Dance will be performing in the opening ceremony of the Pyeongchang Olympics that is to be held next year. Kwon said, “I was planning to study more in Paris next year. However, I decided it’s more important to make meaningful memories with my friends here. I’m truly looking forward to it.” Kwon still has a bright future ahead of him. Instead of making ambitious goals, he explained that he’s going to stay realistic. “I’m not going to exaggerate my dream such as a ‘global choreographer.’ I want to be recognized in this field and be able to give speeches to people who don’t major in dance.” Kwon has been and will be able to show more in the near future.
