[General][Op-ed] A Different University Culture

From the 23rd to the 25th of May, Hanyang University's (HYU's) spring festival Rachios: Bisang successfully took place with a few major changes compared to previous years. Every university received an official document from the Ministry of Education regarding the sale of alcohol during school festivals. With diverse opinions on this issue, unique scenes were seen during the festival period. On the 1st of May, the Ministry of Education sent an official document making reference to licensing laws. One that sells liquor without a seller's license could be imprisoned up to 3 years or be fined up to 30 million won, according to the Law of Punishment on Tax Criminals. Therefore, the ministry recommended all universities to cooperate with this law. The official document given by the Ministry of Education, on the 1st of May. This sudden announcement just before the festival blocked all students from selling alcohol and created a great confusion, especially for the executives of the student council. Most departments had begun planning out their own events for the upcoming spring festival at the beginning of the year, including the plans of raising profits they make through selling liquor in this festival period. They were suddenly faced with an abrupt change to their plans for the festival and were forced to come up with alternatives, along with other events programed for the rest of the year. On the other hand, some students criticized the existing culture for heavily and solely depending on alcohol to the extent that without it, the whole event falls apart. As a result, no one sold alcohol on campus but instead allowed students to bring their own drinks and arranged numerous food trucks. Other schools provided free drinks when students bought food from their outdoor pubs or gave out free drinks when students paid for the the table. HYU had a preorganization with the convenience store in the subway station so that students could easily purchase alcohol as they wished. Consequently, the drinking culture during school festivals did not disappear. The difference was that the benefit of the selling went to the merchants nearby, instead of the students who held the pubs. A picture of a booth run by the Division of International Studies. A lot of people still enjoyed HYU's festival by bringing their own drinks. The students’ desire to sell alcohol was not for the purpose of an individual’s profit, but to be used for all students in the major. However, in the name of a healthy university culture, the same amount of money was transferred to the owners of stores nearby. Instead of unilateral oppression, an explanation and a mutual agreement that everyone could understand should have been made. Festivals are held every semester, and therefore the Ministry of Education and all students should both strive for better procedures to reach for a healthy university culture.

[General]Rachios: Bisang

From the 23rd to the 25th of May, Hanyang University's spring festival "Rachios: Bisang" took place with a lot of people having a good time. Several changes were made to this year’s festivities, as they were planned by the Emergency Planning Committee who had to follow a prohibition order from the Ministry of Education not to sell alcohol on campus during the school festival. However, despite the worries, Hanyang had a successful festivala and was able to give HYU students good memories once again. Countless booths for everyone Unlike last year’s festival, the school received sponsorship from various private corporations, including food trucks and an online gaming competition. However, that did not mean that the students did not have enough space to run their own booths. Just like last year, various clubs and departments decorated their own booths and advertised them all over campus. Moreover, the Emergency Planning Committee prepared various utilities and goods for Hanyangians. The lawn in front of the HIT building was crowded with people enjoying a rest in the nice weather. Food trucks throughout the campus delightened Hanyangians' appetites. Clubs did not miss their chance to advertise themselves and recruit new members! News H also had their own booth beside the lion statue and gave out bountiful gifts and coupons. How many photo zones did you find on campus? Ban of alcohol? The Ministry of Education has announced a prohibition order starting in May to outlaw the sale of alcohol by students, since they do not have the approrpiate license to sell alcoholic beverages. Not only were the departments who used to earn profits from the sale of alcohol disappointed, but so were the students who used to enjoy drinking during the festival. Everyone was shocked by the order. However, each division found their own solutions to enjoy the festival with alcohol through unique methods. A number of majors proceeded with their bars by encouraging students to bring their own drinks. Despite the worries, HYU was full of students who visited to enjoy the festival as they have always done. Passion in the Outdoor Theater A total of nine singers were called to this year’s festival. Attracting floods of students to the Amphitheater, the excitement of this year’s Rachios reached its peak. Starting from HYU’s cheering squad, all Hanyangians came together as one during the festival. The crowds in the Amphitheater created a grand view along with passionate reactions to the performers. Yoon-ha, a beloved singer, visited HYU on the 23rd. An acoustic artist, 10cm, also visited on the night of the 23rd. A famous K-pop girl idol group Blankpink visited HYU on the 24th. 2018 spring festival "Rachios: Bisang" reached its end with great applause and compliments.

[Academics][Excellent R&D] Heading for the World of New Physics

The field of physics is largely divided into three categories: particle, optics, and condensed matter physics. Especially in the field of particle physics, the Standard Model is a theory that explains almost every phenomenon in the universe. However, how would you feel if something that you’ve been trusting for the last 50 years turned out to be wrong? Professor Cheon Byung-gu (Department of Physics), is trying to solve this question through his new research project titled "Study of Heavy Flavor Physics using e+ e- Collision." News H met Cheon Byung-gu (Department of Physics) to hear more about New Physics. The Standard Model is a theory describing three of the four fundamental forces in the universe, which are the electromagnetic, weak, and strong interactions, not including the gravitational force, along with classifying all known elementary particles This has been believed to be consistent due to successfully providing all experimental predictions, but leaves certain phenomena, such as dark matter and dark energy, unexplained. Therefore, this signifies there is a certain particle that has not yet been discovered and yet must be in existence. Cheon, therefore, is developing and planning to proceed with research through a Belle Ⅱ experiment, to search for this very particle. Cheon proceeds with his experiment through colliding an electron and a positron together to uncover a new particle through rare decay events. They are so extremely small that making these two particles collide is extremely difficult; therefore, it can only be done using special vehicles, the SuperKEKB collider and the Belle Ⅱ detector, which is a kind of microscope capable of seeing objects smaller than a nucleus. Once these new particles are discovered, they could provide the foundation for a novel theory named New Physics, beyond the Standard Model. An image of an electron and a positron colliding, making an occurance of new particles seen as blue lines. (Photo courtesy of Cheon) The Super KEKB shoots countless electrons from one side and positrons from the other side, providing an instantaneous luminosity 40 times higher than that of the previous KEKB collider. Then the Belle Ⅱ detector identifies the particles, using seven kinds of sub-detector systems, including a calorimeter trigger system, that selects events that are valuable enough to investigate further. The researchers could have better sorted sets of events to analyze through this detector at real time operation, which Hanyang University group is leading its own independent line. Cheon’s final goal is to find a New Physics phenomenon beyond the current Standard Model through the Belle Ⅱ. These physical studies might not look like something that could directly be connected to everyday life. However, much of our abundant technology in our life has its foundation in physics. “Medical technological skills such as X-ray, CT, and PET detectors all started with knowledge of physics. In the field of physics, new discoveries and new acknowledgements contribute to the mental wealth of humankind,” said Cheon. "Don't be afraid to show your abilities as a world leader!" Cheon is currently working not only as a researcher, but also continues his lectures and manages academic affairs as the dean of the Department of Physics. He has online meetings with researchers in Japan every week to continue his research, trying to let his students improve to be talented people who can contribute to society. “I wish to provide my students with an environment where they can work with foreign researchers. I hope all Hanyangians in the 21st century will also be willing to look not only at Korea, but to the whole world.” On Jung-yun jessica0818@hanyang.ac.kr Photos by Kang Cho-hyun

[Faculty]After the Gymnastics Championship

From the 27th to the 30th of April, the 73rd National Assortment Gymnastics Championship, hosted by the Korea Sports Promotion Foundation, took place in Jecheon Gymnasium. Hanyang University’s (HYU's) gymnastics team also actively took part, resulting in the splendid achievement of three students winning medals. News H met these three heros: Kim Tae-hwan (Sport Coaching, 4th year), Im Chang-do (Sport Coaching, 3rd year) and Kim Dong-hwi (Sport Coaching, 2nd year) in the Olympic Gymnasium. From left to right, Kim Tae-hwan, Im Chang-do and Kim Dong-hwi. (Photo courtesy of Sajahoo) As a representative of Hanyang Kim Tae-hwan, the team leader, won bronze in rings and horizontal bar, Im received gold in horizontal bar and bronze in parallel bar, and Kim Dong-hwi earned a silver in vault. The National Assortment Gymnastics Championship, the first competition in this year’s season, is especially important to all gymnasts as it determines their pride as university representatives. After the championship was over, all three students showed a sense of relief and regret at the same time. Kim Dong-hwi was injured during the preparing period, so the championship’s result gave him an especially great delight. “I couldn’t prepare as much as my fellow players, but I am extremely relieved with my result. I simply think I was very lucky and will practice harder,” reminisced Kim Dong-hwi. Now that the National Assortment Gymnastics Championship are over, the three students took a short rest and prepare for the next national games, taking place in August. However, in order to get enough practice during a season, a day is too short for all athletes at HYU. All three students major in Sport Coaching, which is a division within the ERICA Campus in Ansan, but live and practice at the Seoul Campus. Therefore, they wake up at 6 o’clock to get to their classes on time, and return back to Seoul in the afternoon. Then they spend three hours practicing in the Olympic Gymnasium until 10 o’clock. It is indeed a harsh schedule for anyone, trying to find success both in academics and in training, so they tend to rely on each other to get better results. News H was able to find them still in the Olympic Gymnasium even after the game was finished. The life of a gymnast All three students started gymnastics at a very young age, without any determinate thoughts. Kim Tae-hwan and Im Chang-do both started in their second grade of elementary school on the recommendation of their teachers, solely for fun. They simply did what they were told, found they had talent in it, and arrived at their current destination of HYU. “I didn’t have particular interest in gymnastics until recently. However, I found out that exercising and managing myself physically was fun,” said Kim Tae-hwan. Kim Dong-hwi laughed out, “I started sports because the gym gave us candies.” These not-so-impressive little chances changed their lives - these students who are just about to become professionals. Kim Dong-hwi hasn't fully recovered from his finger injury sustained before the championship, but still achieved a great result. Despite their passion towards gymnastics, their current situation at school is not as welcoming. The HYU gymnastics team consists of two students from each grade, making a total of eight athletes. However in 2014, this team was on the verge of disperse, due to financial problems within HYU. The gymnastics team, along with the judo and track team, was temporarily eliminated, until a demonstration was made to receive these teams back. After these incidents, the gymnastics team is still lacking financial aid and are continuing the practices through their own willpower. They suffer with countless injuries, especially with their shoulders, backs, and ankles, but are continuing their practices to achieve better results. All of these students had the same goal – to lead the HYU gymnastics team to victory. They all had their individual dreams as professionals, but at the same time had their own pride as a Hanyangians. “I want to change the perception of people to think of HYU when they hear the word gymnastics,” smiled Kim Dong-hwi. By spending most of the day together as friends, a family, and a team, all three athletes created a single, bright atmosphere. Now these students are off and ready to express themselves in all the tournaments facing them. The HYU gymnastics team is planning to practice hard again before the next big event in August, to show their abilities even more. On Jung-yun jessica0818@hanyang.ac.kr Photos by Lee Jin-myeong

[General]Where All Brilliant Dreams Start

Do you have any unique ideas? Are you wishing for a company of your own? Hanyang University (HYU)’s Startup Support Foundation is up and ready to help you in all areas. On the 17th of February, the opening ceremony of the 247 Startup Dorm was held by the Startup Support Foundation. This renovated dorm on the fifth floor of the HYU’s first student resident hall is now open for those with innovative and outstanding ideas. For better preparation The opening ceremony of the 247 Startup Dorm was successfully held. (Photo courtesy of Startup Support Foundation) Until last year, the fifth floor of the first student resident hall was used for students preparing to take bar exams. However, as the law school system was implemented, this place was renovated with the intention to support the top one percent of the students who are planning start-ups, just as the top one percent of students studying for the bar exams used to reside there. Therefore, the students living in the the 247 dorm receive full scholarship to fully concentrate on their work to become global leaders. The 247 Startup Dorm is named to signify a place where dreams of startups live 24 hours a day, 7 days a week. A total of 30 students are accepted to this dorm each year, through an evaluation of volition, readiness, related activities, and the exellence of their start-up ideas. The evaluators look for teams who are able to utilize high-technological skills or have ideas related to the fourth industrial revolution. After they went through the document evaluations and interviews, students started moving in at the start of this semester. These selected students go through various programs that assist them in better preparing for their startups. 10 rooms with three students in each are arranged, along with a co-working space, a coaching room, an administrative office, and a startup mentor room. Students can live with their partners for a longer time period through this dorm, and can maximize their creativity through different spaces that allow them spaces for conferences and brainstorming. Moreover, mentors and administrators are frequently standing by to help the students as much as they can. A picture of the co-working space. Students can freely use these rooms to work. Creating future CEOs Yoo Hyun-oh, the leader of the Startup Support Foundation, detailed his great expectations for this dorm. “We are planning to support the students living in the dorm as much as we can, both technically and financially,” explained Yoo. There are a few mandatory classes for the students living in this dorm to take. They can choose between different startup lectures and can receive advice from their designated mentors. Senior and junior mentors who are already in the field are also planning to help out, to help increase the students' readiness. The team members go through autonomous meetings and seminars to prepare weekly and monthly reports. "I wish a lot more students were interested in startups. We now live in an era where a person has more than one job in a lifetime." Lee Kyung-tae (Business Administration, 4th year), a student living in the dorm with two other teammates is running a service named "Kids ground." This is a platform service that provides children with various daily classes around them. “Our three teammates each live in Paju, Hanam and Nowon, which results in quite a lot of commuting time. The business's efficiency level dropped due to this factor, and we decided that 247 Dorm was the perfect solution for us,” explained Lee. Chung Koo-hyun (Polymer and Nano Science Engineering, 4th year), preparing for a customized skin care system, also had a similar thought. He explained that the biggest advantage comes from the fact that he is living with the people who create the most synergy. “I think the dorm gives stability to all teammates. Unlike normal corporations, startup companies can have an unstable sense of belonging. By having a united living space, I believe it gives motivation along with cohesion to teammates,” said Chung. The 247 Dorm is open for anyone with ideas and passion. The Startup Support Foundation is trying not only to support the students, but to also give them a visible objective that they can pursue. “I hope that the 247 Dorm can work as a milestone for better, more globalized companies that start at HYU. We plan to constantly manage and help all students with brilliant ideas,” commented Yoo. On Jung-yun jessica0818@hanyang.ac.kr Photos by Choi Min-ju

[General]A Different Start at Hanyang

Last year, the student president of the College of Engineering was elected to be the head of the Emergency Planning Committee at Hanyang University (HYU). However, as another election for the student body president was foundered in March, the Central Operation Committee had to hold another election to choose the first semester's head of the Emergency Planning Committee. On the 1st of April, the president of the College of Policy Science, Cho Sung-jae (Policy Studies, 2nd year), was elected as the head of the committee. Now as a new leader of HYU, News H visited him to hear more about Hanyang's current situation and its future. Becoming someone representing HYU The Central Operation Committee of HYU had a rough start this semester. Without the official student union, someone from the Central Operation Committee had to hold an additional post as the head of the Emergency Planning Committee. Therefore, on the 26th of March, the head of the Student Club Association held an election to determine the head of the Emergency Planning Committee. As the presidents of each college had their own plans and work to do for their department, the head of the Student Club Association willingly gave a hand to all representatives. News H met Cho in the Student Union room, where he does his work. However, a question regarding school regulation was posited, as it is policy that the president of a college must become the head of the Emergency Planning Committee. Therefore, Cho was then re-elected as the head of the Emergency Planning Committee. “Just like a joke, I was re-elected as the head of the Emergency Planning committee on April Fool’s Day,” laughed Cho. He now has a lot of burdens on his shoulders. “As far as I know, I don’t know a single case conducted by the HYU Emergency Planning Committee during the semester. I therefore don’t have a lot of knowledge, but will just have to try my best.” Cho was concentrating on the General Student Representatives Council when the interview took place. This council, happening on the 10th of April, would be his official start as the head of the Emergency Planning Committee. Cho also showed his passion and worries towards the school festival scheduled to take place from the 23rd to 25th of May. “I have only been to one General Student Representatives Council and one school festival. I will definitely lack helping hands when preparing these events. I am, and will continue to receive advice from the people who already have more experience, and will try to give all Hanyangians satisfaction,” said Cho. Moreover, he is planning to continue working toward the construction of the new school dorm that the 45th Student Union has approved, and is also planning on helping implement more volunteer activities to benefit rural communities. 2018, as the year of the 46th Student Union, is run as the Emergency Planning Committee. (Photo courtesy of HYU Student Union Facebook page) As the head of two parties As countless incidents are rapidly taking place, Cho also expressed uneasiness towards the people around him. “As I ran for the president of the College of Policy Science, I had certain pictures drawn in my head. However, as I became the head of the Emergency Planning Committee, I realized it is inevitable that I have some deficiency. I would like to take this opportunity to apologize to my colleagues in the College of Policy Science and my fellow student council members,” said Cho. He didn’t even have enough time to consider this matter with his student council members before he became the head of the Emergency Planning Committee. He wanted to express his love and thankfulness to his executive members. Cho expressed his concerns about having become the head of the Emergency Planning Committee without much prior preparation. “The biggest hardship for me is the worry that I am not capable enough for this position. I don’t want to give inconvenience to the fellow Hanyangians, and therefore I am trying my best to become a person that can think of the overall school before myself,” said Cho. The detailed plans for the school festival and the processes for the dorm had not yet materialized as it had only been five days since his election at the time of the interview. At the same time, he showed great knowledge, thoughts, and determination even though it hadn’t even been a week since his election. "I want to leave a good precedent for potential happenings like this in the future." “Hello, I am the president of the College of Policy Science holding an additional post as the head of the Emergency Planning Committee. I think of myself as an individual that lacks the personal capacity to fulfill such a role. However, as the head of the Emergency Planning Committee, I believe I should strive for all Hanyangians’ benefits no matter what my motivations were, or how I was elected. Even though I may not be perfect, I will try to make a better environment for all my colleagues to the best of my ability. A lot of students may not know me as I have only worked in the College of Policy Science. Therefore, I believe introducing myself through my actions would be the best method. Despite my deficiencies, I would be extremely thankful for all your support and well wishes. Thank you!” On Jung-yun jessica0818@hanyang.ac.kr Photos by Lee Jin-myeong

[Academics][Researcher of the Month] Controlling Hydrogen in a Chemical

During the 2018 Pyeongchang Winter Olympics, Hyundai allowed free trial rides of NEXO, their new fuel cell vehicle, to twenty thousand people, deriving huge attention and public interest on the new innovation of hydrogen-powered fuel cell vehicles. A total of 733 vehicles were reserved on the 19th of March which was the first day of sale by pre-order. This attention to fuel cell vehicles has also increased the interest in the methods the consumers can receive their fuel: hydrogen. Professor Suh Young-woong (Department of Chemical Engineering) introduced a novel method of the transfer of hydrogen through his research, "2- (N-Methylbenzyl) pyridine: A Potential Liquid Organic Hydrogen Carrier with Fast H2 Release and Stable Activity in Consecutive Cycles." Suh's research paper was published in the ChemSusChem journal. Hydrogen is the main fuel cars like NEXO require in order to run. However, researchers face an immense difficulty when working with this sensitive gas. Hydrogen is great when powering the car itself. However, the transport of this gas requires much pressure and delicacy. For example, if hydrogen is made in Ulsan, it needs to be transported to major cities such as Seoul, since people will need to charge their cars. In order to transport this hydrogen, the gas needs to be pressured under 700 bars (the unit of measuring pressure), with specially produced tanks. This presents the danger of enormous explosion as well as economic problems. Collaborating with three other universities to alleviate these current concerns, Suh helped introduce a new chemical substance that can store and release hydrogen safely. This new chemical material allows hydrogen to inflow and release within itself at a certain temperature. This results in a massive improvement over the current status as it can transport much more hydrogen in a single tank, with much more safety. Moreover, they can release hydrogen from the chemical at 230 degrees Celsius, while the present technology requires a temperature of 270 degrees Celsius. This chemical material can even be reused up to a hundred times, which even makes it more efficient. The image of the new chemical structure The two arrows are showing the inflow and the release of Hydrogen. (Photo courtesy of Suh) This research took each of the three teams one and a half years to finish. They had to go through endless trial and error procedures with seven different chemicals. “There wasn't any preliminary research we could have referenced. Some chemicals didn't work, and some chemicals would work but released hydrogen at the same 270 degrees Celsius,” reminisced Suh. As a result of their efforts, Suh was able to find a method that could inpour and discharge hydrogen from the chemical. This chemical is not yet fully developed in its validity. However, this is the closet chemical that is on the verge of commercialization. "Communicate with a lot of people and practice reading and writing!" Suh is currently researching not only the storage of hydrogen, but the creation of hydrogen itself. His research team is working on producing hydrogen from biomass, which is organic matter whose residual energy can be harvested to produce consumable energy. He is trying his best to develop technology related to hydrogen, an alternative fuel the whole world is anticipating. “As a professor, I want to produce a lot of outstanding researchers to conduct better research in society,” said Suh. “And to all Hanyangians, I wish for each and every one of you to find your own unique path and to fully dedicated yourself to it!” On Jung-yun jessica0818@hanyang.ac.kr Photos by Kang Cho-hyun

[General]A Hand for International Exchange Students

A new school, a new country, and a new environment are things that could definitely make an individual anxious. As international exchange students arrive and face these situations, Hanyang University (HYU) lends them a big hand. For those international students Hanyang University (HYU) Office of International Affairs newly organized a student group called ‘Hanyang Global Lions’ that consists of existing students of Hanyang Univeristy. Even though this is their first try, their passion is being delivered to this semester’s international students. Not just lions, but global The 25 members of the Hanyang Global Lions are trying their best to help exchange students from around the world feel comfortable in their new Hanyangian environment. Lim Chan-ho (Mechanical Engineering, 4th year), President of the Hanyang Global Lions, explained,“Hanyang Global Lions are the representative student group belong to Office of International Affairs.” As most of exchange students are very new to Korea and begin their semester at HYU without enough knowledge, ‘Hanyang Global Lions’ manages various programs and events for them to feel get to know more about Korea during their stay in Korea here. "I wanted to help exchange students to feel that they belong to HYU while they are staying here during their the semester." ‘Hanyang Global Lions’ is a newly organized student group covering existing volunteer group ‘Hanmile’, which was a buddy-matching program. Now Hanmile has changed its name to HY-BUDDY program and it aimed to help exchange students to begin their semester with friends. Not only matching exchange students with buddies, ‘Hanyang Global Lions’ manages various events and planning many others. February – International students’ orientation. Hanyang campus tour March – A welcoming party in Seong-su, Seoul tour in six different areas April – Rice cake making experience. Watching a baseball game. Field trip to Gyeong-ju May – Running a booth in the school festival June – Farewell party To make unforgettable memories Even though it’s the Hanyang Global Lions's first year, they are running and planning successful events. First of all, the regular HY-Buddy program allows international students to have a Korean friend they can directly talk to. This allows international students to make Korean friends, along with receiving help in adapting to a new environment. Manuel Kubach (Business Administration, 3rd year), a buddy of Lim’s, also showed satisfaction in what he was able to experience in Korea. “My buddy is doing a great job and is helping me anytime I need him. We are not only meeting up at official buddy events but also personally. I once went to a Korean barbeque with him which was a good opportunity to make other Korean friends,” said Kubach. They successfully held a welcoming party with around 160 guests and are proceeding with other events. “Except for one region, all 5 regions of the Seoul tour application are already full. Our members and I are boosted through this level of participation,” explained Lim. The Hanyang Global Lions are already contacting baseball clubs and accommodations in Gyeong-ju to provide them with a safe trip that will leave the international students with lasting memories. “The executives had eight to nine hours of meetings during the vacation to make great events, and I want to give extra thanks to them,” said Lim. A photo of international students at the welcoming party (photo courtesy of Lim) The Hanyang Global Lions are now searching for more enthusiastic students willing to help out friends from other countries. The second recruitment is going to take place in May, after advertising throughout April. The second team of Hanyang Global Lions will start their work for next semester in June. A lot of international exchange students are waiting for their help! On Jung-yun jessica0818@hanyang.ac.kr Photos by Choi Min-ju

[Academics]Constructing an Image of a Region

Everyone has a certain image of a location, whether they received this image directly or passively. In the study of tourism, this image is also a field that needs to be studied in order to understand the behavior of tourists. Professor Kim Nam-jo (Division of Tourism), showed this relativeness through his article "Destination Personality, Destination Image, and Intent to Recommend: The Role of Gender, Age, Cultural Background, and Prior Experiences." Kim developed the research with his student, Kim Woo-hyuk. “This research started with the popularity of ‘Gangnam Style,’ when the location Gangnam caught the world’s attention,” Kim started off. "Gangnam Style," a popular song by Korean artist Psy, was a big hit, ranking second on the Billboard Hot 100 Chart. Along with the popularity of the song, the interest towards this particular location named Gangnam also drew interest from foreign tourists. Therefore, Kim and his student, Kim Woo-hyuk, started research on the interpretation and the image of this particular area. Kim's research attempted to comprehend the characteristics of this area and the image tourists have of it. “There are two types of images tourists receive,” explained Kim. An organic image is an image a particular individual receives without intention. For example, people living in or around Seoul are mostly familiar with Gangnam through their everyday experiences such as interactions with the news, transportation, or the people around them. This allows a natural formation of an image of Gangnam. In contrast, an induced image is made through the opposite manner. It is created when an individual intentionally seeks out information about a particular region. “When these two images combine, the image of the region Gangnam could be strengthened and lead to the creation of a destination personality. This destination personality can lead to an actual effect of visiting the region,” said Kim. As tourism is not a study that has direct cause-and-effect relationships, they had to spend additional time and effort verifying the existing logical structure. They re-examined and demonstrated the structure based on standards such as the destination personality, image, and intention of the tourists. Moreover, they connected their proven logical structure to satisfaction and loyalty, to search for a point to emphasize when promoting Gangnam. This type of research required actual responses from tourists, which were collected though surveys and in-person interviews. Kim had surveyed 20 questions and interviewed around 320 people. Kim enjoys his busy, everyday life. Through this research, Kim was able to prove the logical structure they had initially started with, through the example of Gangnam, known to foreigners through the song "Gangnam Style." Currently, Kim is conducting research on Gyeong-ju. Due to the recent earthquake that occurred, Kim is studying the changes in the area's image after the incident. “It’s only a small region of Gyeong-ju that was damaged from the earthquake. However, the overall image of Gyeong-ju has become negative,” explained Kim. Seen through this example, Kim is working on a strategy that could be made to solve this kind of prejudice. Kim is not only conducting research, but he is also actively working as the President of the Tourism Sciences Society of Korea. He is enjoying every project he is involved in, and is planning on continuing to do so. “A lot of students aren’t sure of their passion or their future career in our school. Even though you aren't sure, there is definitely something inside you that makes your heart pound. I hope every Hanyangian can find and specify their dreams and bring them out to the bigger world. Widen the prospects of your thinking skills!” On Jung-yun jessica0818@hanyang.ac.kr Photos by Lee Jin-myeong

[Academics][Researcher of the Month] Producing Energy by Wearing Clothes

Clothes that create electricity is not something in a movie anymore. In the midst of searching for various renewable energy, Professor Hong Jin-pyo (Department of Physics) created a new energy source that is created through friction in a single thread, as demonstrated in his research, ‘Hierarchically Nanostructured 1D Conductive Bundle Yarn-Based Triboelectric Nanogenerators.’ Hong conducted his research on energy-producing threads. When designing a wearable device, people generally think of light and slim devices attached on one’s clothes or body, usually charged by a solar heat system. This is referred as a two-dimension technology, as an object is placed upon another object. This does have its own benefits but also contains deficits such as weight and energy sources. Therefore, Hong created a one-dimension energy source – a thread that is used when weaving clothes. “Once a material is attached to clothing, the efficiency lacks uniformity,” explained Hong. He invented a thread that can produce energy itself, without having to attach anything onto a particular piece of clothing. The threads that make up the clothing could create energy itself. This thread, also named as a ‘triboelectric nanogenerator’, is a structure made from the notion of friction that we experience in our daily lives. For example, when we rub a balloon to our hair, friction occurs, resulting in a form of spiky hair. This phenomenon occurs when an electron is moved from one object to another, when these two objects continuously collide with each other. Depending on the characteristics of an object, one object would lose electrons and the other would gain electrons, meaning some sort of slight energy is formed. In this thread, polymer and aluminum are used; the former collects the electrons and the latter releases the electrons. Therefore, once the body wearing the clothing weaved from this thread moves, energy is created. The microscophic strucuture of a thread. (Photo courtesy of Hong) This triboelectric nanogenerator is still in the midst of its research. As this thread is extremely thin, Hong’s research team created a conductive bundle yarn so that they could have more strength. Moreover, he attached polymer-like nanostructures onto a single thread, so that the thread could have an increased surface area of energy production. Once energy is created through a larger surface area, bigger energy could be created within a single thread. This whole process is also known as a tribo electric effect. This one-dimension thread has a bright future in front of them, as technology closer to human are fondly being conducted on. “Once a sensor could be attached onto the thread, even more tasks could be done. This sensor could send whatever information they require to the owner’s smartphone, once the sensor adapts a Bluetooth function,” commented Hong, when asked about the future of this invention. He wished that this function would be able to let citizens to have control of their IoT (Internet of Things, a system of interrelated computing devices, mechanical and digital machines, object, animals or people that are provided with unique identifiers) through their energy producing clothes. "Keep trying! No matter what!" As Hong has not majored in clothing and textiles, he is not yet an expert of clothing, but has not been afraid of pioneering this area. “I had been proceeding my research in semiconductors at first. As new technologies evolved, I believed it was important to keep up with these changes to improve what I have been initially doing,” reminisced Hong. As he had achieved an unexpected success through his passion, he also gave the same advice to all Hanyangians. “Don’t make excuses. What really matters is whether you tried your best or not. I wish all of you can improve yourself through endless challenges!” On Jung-yun jessica0818@hanyang.ac.kr Photos by Choi Min-ju and Lee Jin-myung
