[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]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.

[Event]Find Your Perfect Job, Bright Future!

"The desire of Columbus for the discovery of the world is reenacted through Hanyangians!” Here is the ambitious motto of the Job Discovery Festival of Hanyang University (HYU) in the era of exacerbating unemployment. Every September, the Career Development Center (CDC) and the Office of International Affairs (OIA) design and host the Job Discovery Festival to provide students of HYU a chance to seek information and real life stories on 154 companies and occupations in South Korea. News H visited the event held on the 5th and 6th of September to become a Columbus of the job market. Both local and international students are zealously paying attention to the recruiters and their consultation. Discovery of occupation, summary of information This year, 154 companies have participated in the career fair, which was a 23 percent increase compared to last year. The most intricate part of the fair was that it prevented any exclusion of students in employment as its theme this year was ‘diversity.’ Along with the booths for Korean students, designated booths for the handicapped students and foreigners were also prepared. The fair included individual consultation with the recruiters, providing truthful information that cannot be found on official reference. Professional advice for employment documentation that many students find difficult to prepare was also given. “The Job Discovery Festival has always provided great opportunities for students to comprehend more specific information on companies while recruiters can meet their possible candidates through the fair,” said Shin Yong-jin of the CDC. The fair is hosted every September, considering the primary employment season of South Korea. “The main reason to hold the festival in September is because of two reasons. First, majority of Korean firms recruit personnel in the second semester, and second, the CDC believes that this fair will arouse students’ attention on the beginning of term,” reminded Shin. Out of the 154 firms who participated, 12 of them were active in recruiting handicapped students. The booth for the disabled students was arranged to explain to them the spectrum and the process of employment. Also, several Japanese companies also took part in the fair to employ Korean students due to the aging population. “The place, exclusively prepared by the OIA for foreign students, provides them deeper information on careers they could pursue in South Korea with all the information translated in various languages for their convenience,” explained Park Jin-ju of the OIA. Advice from the bottom of alumni’s heart The recruiters of the fair from each company were mostly graduates of HYU. As the Job Discovery Festival was gaining momentum, juniors and seniors flocked together to hear sincere advice from the alumni. “It was a great experience for me to learn about the plethora of firms in Korea. Also, information that cannot be found online was provided by our alumni recruiters along with their heartfelt encouragements,” said Hwang Jong-min (Earth Resources and Environmental Engineering, 4th year). Also, Umeh Zeno from Nigeria (Economics and Finance, 1st year) remarked, “even though I was only a freshman, I could learn a lot about employment and its process here in South Korea. I was impressed with the fair’s scale and I wish to visit here again annually.” Umeh is meticulously observing the employment process of the LG Company. Numbers of alumni gladly welcomed their juniors to their career booth. Kang Min-chang (Department of Mechanical Engineering, ‘14), currently working at SK Plant-Mechanical Team, has also disclosed his sincere advice to his juniors. “I remember wandering around at this festival, desperately looking for where I wanted to be employed two years ago. I am happy to be here now, helping my juniors with their career, and I’ve been advising them to apply their full strength at the interview to make a good impression on employers,” said Kang. Kang wishes that Hanyangians who successfully obtain employment will gladly help their own juniors for their future. The Job Discovery Festival of 2017 was packed with students, revealing the reality of the high unemployment rate. South Korean and foreign Hanyangians willing to be employed locally may have to be faced with moments of failure. However, numbers of frustration cannot defeat the sense of accomplishments in further life. Just like, after the storm--comes calm. The future of Hanyangians will shine bright despite the hard times of this era! Kim Ju-hyun kimster9421@hanyang.ac.kr Photos by Choi Min-ju

[Academics]Founding Father of the Pragmatic Application of Stepping Motors

Every moving object needs a power plant. In the industrial world, permanent magnet stepper motors are widely used, which are designed with permanent motor (PM) rotors that are commanded by electrical pulses. In his paper “Nonlinear H2 Control for a Nonlinear System with Bounded Varying Parameters: Application to PM Stepper Motors,” Chung proposes a new nonlinear H2 controller for the PM motors that can increase the efficiency both in its speed and practicality. Chung is the pioneer in South Korea to discover new methods of applying nonlinear H2 control for a nonlinear system. Utilization of the PM motors vary from household purposes such as printers to industrial purposes such as gas systems and cars. Since its earlier usage from the 1970s, these motors have thrown questions to scientists and engineers on its formula. “Despite the fact that these motors are popularized in the industry, there are constraints in the PM motors, such as speed restriction,” said Chung. To solve this problem, engineers have discovered the DQ (direct quadrature) transformation of the motors which is a tensor that rotates the reference frame of a element vector matrix to simplify the analysis of it. “My research team has found that DQ is comparatively inefficient in terms of energy saving and cost control. Thus, we detected a new mathematical method to replace the DQ transformation,” said Chung. Often times, engineers used the linear system to control the PM motors. A linear motor is an electric motor that has its stator and rotor unrolled, so that instead of producing a torque, it produces a linear force along its length. However, linear motors are not necessarily straight, which causes restrictions in speed. “Formula of the linear system consists of homogeneity and additivity, and the main point of our research was to minimize the relationship between them using the H2 control system,” emphasized Chung. This FOC (Field Oriented Control) with the H2 system went through an experiment with other traditional methods for a comparison. “The results were outstanding as more simplified version of mathematical calculation and less usage of sensors beforehand were required, while the tracking errors and energy cost were reduced respectively,” said Chung. The green line of case 3, which uses the FOC (Field Orientation Control) of the H2 control shows the extreme distinction in tracking errors. (Photo courtesy of Chung) The most desired application of this method is on the intelligence vehicle, which is a car that can drive by itself without any interference of a driver. “Learning about the motion control, which is the main issue of my paper, is the most important criteria of designing a self-driving vehicle. This study allowed me to grow this industry rapidly in five years,” astonished Chung. Currently, Chung’s research lab for the intelligence vehicle based on motion control is the best in Korea which acquire all the knowledge on the sensors, actuators, and control algorithms. Chung’s passion for science was conspicuous from the days he used to make a radio on his own. When he started gaining interests in engineering, motion control grabbed his sight. “The stepping motors and their control system are fundamental technologies. I thought that developing them into pragmatic applications would be exciting,” reminisced Chung. Currently, Chung is passionately contributing to the scientific and technological advancement. For the visible result, he had launched the IEEE (Institute of Electrical and Electronics Engineers) ‘s CDC (Conference on Decision and Control) conference at Jeju Island, South Korea. “This is the first time ever that the CDC conference is being held in South Korea and I consider this the greatest achievement of my academic life so far,” smiled Chung. Chung is currently working on developing more advanced intelligence vehicles. Chung’s everlasting hope for his students is that they could study both science and liberal arts. “I wish South Korean educational system could teach students to embrace the joy of learning. This will eventually rear the bright sprouts of Korea,” said Chung. Kim Ju-hyun kimster9421@hanyang.ac.kr Photos by Choi Min-ju

[Event]International Invitation from Hanyang University- HISS

A month long, annually held exchange student program HISS (Hanyang International Summer School) welcomed the foreign students from all over the world on July 1st. HISS has met its 20th anniversary with nearly 2,000 international students in the program, which initially began in 1997 with 20 students. Standing out in all South Korean universities with the highest number of foreign participants, HISS of 2017 has drew up its curtain. The first culture experience program of Week 1 at HISS has been successfully ended. (Photo courtesy of the OIA) Catching two birds with one stone HISS has two goals to achieve for the provided month- academics and Korean cultural programs. Within only four weeks, it may seem hard to provide both educational and cultural programs to 2,000 foreign students. However, OIA (Office of International Affairs) of Hanyang University (HYU) has efficiently divided the academic workload and cultural experience program through subtle time management. “OIA has frequently established more lectures during the HISS which count up to 120 now. Also, enhancing the quality of the classes provided by HYU is another primary mission of ours,” said Angie Lee of the OIA. It included about 120 lectures on engineering, literature, international studies, and more. Weekly cultural programs for the exchange students are also planned by the OIA. On week 1, foreign students who were interested in Korean music, especially K-Pop, had a visit to the SM Town, which is a musical tourist site sponsored by SM Entertainment. On the second week, a friendship party was held on a cruise floating from Yeouido to Jamsil Han River Parks. Later on, OIA planned to escort the foreign students to an amusement park called Everland and a waterpark Carribbean Bay. Their last activity will be held at the Boryeong Mud Festival. Exchange students are enjoying their second activity of the HISS on the cruise. Students are smiling after experiencing various programs provided at the Cruise Party. The highlight of all activities was the cruise party, which News H accompanied with. The party took about two hours where students could enjoy the band performance, special foods, and the beautiful night view of the Han River. “This is my first time staying in Korea, and in Asia. I am enjoying the active atmosphere of Koreans and their unique culture. I’m also looking forward to the HISS programs every weekend,” said Elias El Araj from Netherlands. Also, Mika Auyezkhan from Kazakhstan showed her love for the Korean culture- “I was always interested in Korean culture and I am glad that I chose Hanyang University because it let me experience a lot in South Korea. I also love how they have solid educational structure.” Mountain to surmount Behind the delightful programs of the HISS, there are three OIA staffs and other volunteers who support the whole program. “As the number of participants is increasing every year, it becomes harder for us to manage all students’ circumstances like health. We already had a few visits to hospital with our students,” laughed Rick Punt of OIA. However, despite the augmenting size of the HISS program, OIA and HYU volunteers are paying careful attention to the students to prevent any accidents. “We are still proud that Lee, Punt, and I are leading the HISS, even though our July in calendar disappears completely,” said Min-joo Park of the OIA. “Without love for the HISS, I don’t think the program can be so successful. As we recap all students’ overall thoughts and reviews, we will constantly strive for the better HISS every year,” added Lee. Friendship between Korean volunteers of HYU and foreign students from the globe has become stronger through various activities. Aside from the internal difficulties, external factors such as international circumstances and the state of affairs also impact the HISS. “This year, students from the United States dwindled due to the recent North Korean crisis. However, number of Singaporean and Kazakh students augmented due to the increasing interests in the Korean culture,” said Punt. HISS, where unforeseeable and urgent situations sometimes take place, still remains as one of the best exchange program in South Korea due to the efforts people at the backstage put in.

[Academics][Researcher of the Month] 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.

[Academics]Factors that Influence Donation Intentions via SNS

Social Network Service, also called as SNS, is rapidly developing its features to suit the current information-oriented society. In the 21st century, various types of communication do not require individuals to be nearby physical. Keeping pace with the times, the behavior dimension behind donating has also been altered into an online format. With the Internet's prompt speed and secured environment, people can now donate to charity organizations found on SNS pages. Through his paper “Factors Influencing Intention To Donate Via Social Network Site (SNS): From An Asian’s Perspective,” Professor Ahn Jong-chang, Department of Information System, investigates the correlations between people’s intention to donate and online external factors. Ahn is explaing the correlation between four external factors and the donation intention via SNS. Professor Ahn’s study examines whether external factors influence people’s general attitude towards online donation, and their intention to donate via SNS. These four external factors are defined as charity project, charity organization, Internet technology features and SNS features. Professor Ahn conducted an online survey of 258 respondents from South Korea and Malaysia based on the framework of the structural equation modelling- a multivariate statistical analysis technique used to analyze structural relationships. There are preceding researches regarding SNS donation intentions. However, these researches analyzed the correlation between the donation intention and only three external factors- charity project, charity organization, and the Internet technology features. “Since Internet 1.0, which was entirely made up of web pages connected by hyperlinks, has developed into Internet 2.0, the web characterized by change from static to dynamic or user-generated content and the growth of social media, my research partner and I came surmised that these multilateral interactions between users of SNS will also affect the donation intentions,” said Ahn. After analyzing the responses, Ahn discovered that the Internet technology features significantly influence general attitudes of people towards online donation, and general attitude positively contributes to people’s intention in donating via SNS. “We have found the full mediation effect of the general attitude towards online donation on the relationship between Internet technology features and intention to donate via SNS,” mentioned Ahn. The framework of the structural equation modelling above shows that Internet technology features influence people's donating intention through SNS. (Photo courtesy of Elsvier) However, the rest of the factors- charity project, charity organization, and the SNS features, were found to be ineffective, compared to the Internet technology features. Professor Ahn emphasized the importance to strengthen the Internet’s technological environment. “This consequentially means that if charity organizations long to fundraise significant amount of donations via SNS, they have to strengthen the Internet environment especially in the security field.” Although the research was based on an online survey of 258 people, Ahn says that his results cannot be generalized globally. “The research puts basis on the online survey conducted with Malaysian and South Korean respondents. This particularly limits my conclusion to the Asian areas,” highlighted Ahn. Professor Ahn produced his paper with a graduate student from Hanyang University, and he revealed the arduousness of the small research group. “Unlike a scientific research which can have a definite and distinct cause and effect results, this kind of social science research may incur ambiguity. Thus, clear and logical reasoning and firm data are considerably crucial,” asserted Ahn. The long road to publication taken by Ahn was strenuous. Due to the limited size of his research team, Ahn had to bear significant pressure and duty. Also, the time taken to finalize the paper took longer than other bigger research groups. However, it was Professor Ahn’s perseverance and passion towards academic achievements that produced promising consequences. Professor Ahn Jong-chang is expanding his research area to the West. Currently, Professor Ahn is working on submitting dissertations on the same topic but in the perspective of the West. It is his hope that the research environment of the social science field will be meliorated. “I wish all students of Hanyang University will continue working in their fields with passion. Just like Confucius said, the blissful time will come, if we make efforts not with anguish but with joy.” Kim Ju-hyun kimster9421@hanyang.ac.kr Photos by Choi Min-ju

[Academics]Genetic Architecture of Rheumatoid Arthritis

Rheumatology is a rather unexplored branch in the medical field, and its causes and cures have not yet been fully prepared. However, Professor Bae Sang-cheol of the College of Medicine at Hanyang University stands as one of the pioneers to define and research the causal factors of rheumatology and discover better remedies. In his research “Update on the genetic architecture of rheumatoid arthritis”, Bae clearly defines the factors of rheumatoid arthritis with regards to human genetics, and predicts the possibility for precision medicine. Bae is one of the pioneers in Korea to research and advance cures rheumatoid arthritis. In his paper, Bae has organized the causes and possible remedies for rheumatology researched in the last five years- collecting all data with advanced medical technology. Rheumatism hasn't been explored completely yet, so its causes are only speculated to be genetic and environmental factors. “Rheumatism is an autoimmune disorder, which means that the causes tend not to be external factors. It's assumed that 60% of the causes is the immune system attacking upon itself, acting out of misconception,” said Bae. Human genetic studies into rheumatoid arthritis have uncovered more than 100 genetic loci associated with susceptibility to the disease. This means that the majority of factors are highly shared across multiple ancestral populations. Bae and his fellow researchers organized the data on impaired immune processes and disease phenotypes for rheumatism. “The ultimate goal of this research paper was to enhance the possibility of finding the repurposed drug for each rheumatoid arthritis patient,” mentioned Bae. Since 2005, medical technology developed rapidly, especially in the genome field. For about a decade, a significant amount of the data was collected on genome structures that are likely to influence the rheumatoid diseases. “The grand development in this area is that now, technology can examine the whole genetic variants, instead of individual ones, using the whole genome analysis technique,” said Bae. Rheumatology-related genetics directly affect gene expression and protein function, and also influence cell signaling pathways. According to the cumulated data, this process causes the immune function to be disordered, and spawns diseases in patients. “Proteins that are encoded by rheumatoid risk variants have the potential to help the development of targeting drugs,” Bae explained. Two years were spent in total on the production of this paper, and each process was intricate. First, Bae was invited to co-write with rheumatology experts to analyze the causes and possibilities of advancing repositioning drugs. Then, he had to edit and peer review the analysis and consult with graphic designers to obtain desired pictures of rheumatoid figures. “All these processes took a long time, but interacting with peer reviewers was particularly helpful in advancing this article,” said Bae. Bae stresses the importance of enhancing research on drug repositioning. Drug repurposing, also called as drug repositioning, is applying and utilizing existing medicine to develop into rheumatoid remedies. This technique significantly curtails the cost and time to invent new drugs that target rheumatoid diseases, because existing drugs have already been approved for its pharmacodynamics. Also, the development of precision medicine, which therapeutically targets for personalized rheumatoid state, is being accelerated. “Rheumatoid arthritis does not signal the body in a unique way- it feels more like a cold in the beginning. But alerting oneself to get regular health checks may help to prevent the threatening disease." Bae's ultimate goal is to develop and contribute to organic and personalized rheumatoid arthritis drug invention. His efforts to contribute to the field of rheumatology are prominent, just like his favorite poem, 'The Road Not Taken', by Robert Frost. “Reminding yourself of the original attitude and always trying your best will undoubtedly lead you to success,” advised Bae.

[Event]The 78th Matriculation Ceremony

On the morning of February 27th, the freshmen and their parents gathered at the Olympic Gymnasium in the HYU Seoul Campus to partake in the 78th Hanyang University matriculation ceremony. Freshmen of 2017 gathered together to take their first steps as university students by attending the ceremony- “Made by Freshmen”. The 78th matriculation ceremony of Hanyang University took place at Olympic Gymnasium on February 27th. Prologue Before the entrance ceremony, Hanyang University recruited freshmen for two acts: “Hanyang Dance Leader” and “Hanyang Matriculation Ceremony Organizer.” Hanyang Dance Leader From January to the day before the ceremony, 15 freshmen from various departments practiced dance moves for 4 hours every day, including the weekend. Their performance was directed by Kim Sae-hwan, a dance trainer of Cube Entertainment, including professors from the Department of Dance. Four songs were performed- a ballet dance and three K-Pop songs. The Hanyang Dance Leader team, practicing for the performance. Kim Hyun-ji (Department of Theater and Film) “I am lucky to be a part of Hanyang Dance Leader. I learned how to dance professionally through this program and met new friends from other departments. It was also a great pleasure to meet some Cube Entertainment artists too. I hope that those who see my performance will get to know my bright side!” Kim Hyun-ji (Department of Theater and Film) Kang Hee-won (Department of Electrical and Bioengineering) “I am excited and afraid at the same time to be standing on stage in front of many students, my parents, and professors. I will devote all my energy to performing successfully! I also want to thank my dance team members at Hanyang Dance Leader because we became great friends. Even though I may not be good enough, please enjoy our dance!” Kang Hee-won (Department of Electrical and Bioengineering) Jung Ui-joon (Division of International Studies) “Hello, everyone! I am the center and the face of this Hanyang Dance Leader. (Laughs) I always wanted to become an entertainer so I jumped at the chance when the opportunity came up. Hanyang Dance Leader taught me what real dancing is. The best part during practice was when I saw Hyun-A from Cube Entertainment. She was so beautiful… It was amazing. We will burn the stage with our passion, so please pay attention!” Jung Ui-joon (Division of International Studies) "I have a medicated patch on my neck because it hurts when I do fierce dance moves." Choi Jae-hyuk (Professor of the Department of Dance) “I thank all these students even though it has been a tough month full of sweat and tears. It's totally fine if they make mistakes onstage. I just want them to have cheery memories that they'll remember throughout their life.” Choi Jae-hyuk (Professor at the Department of Dance) "Making memories is the most crucial part of this project." Hanyang Matriculation Ceremony Organizer There also were 17 freshmen behind the stage who made a project proposal to outline and organize the matriculation ceremony. Since January, they met three times a week, from 1:00-9:00 PM, to discuss, plan, and evaluate their outline. The theme was 'Baby Lion', deriving from the Hanyangian mascot HY-Lion. The Hanyang Matriculation Ceremony Organizer team are discussing in a meeting to finalize their plans. “During the month of organizing the ceremony, we all enjoyed becoming friends with each other, getting to know Professor Joo Ji-hee, and learning how to intrinsically and officially organize an event. Even though not every part of our plan became part of the ceremony, we are still proud that freshmen like us could lead such a big event.” Joo Ji-hee (Professor at Department of Theater and Film, director of the team) “It was such a wonderful experience for me to lead this passionate team of freshmen. As major players of the school, these freshmen have shown their love for Hanyang and their excitement to be a part of Hanyang. I believe that if they treasure this pure attitude, they will always be successful wherever they go.” The 78th Entrance Ceremony At 9:30 AM on 27th February, the ceremony officially began with alumnus Kim Myung-kun (Department of Voice, ‘14)'s lesson- teaching the school song to freshmen.

I wish all the best for you, and I hope that Hanyang University will lead you onto the international stage where you can make Koreans proud. Just as it is written in the school song, continuoulsy devote yourselves to your future.” The next session was an academically inspiring lecture given by professor of the Department of Business and a representative at Monaissance, Kang Shin-jang.

It means that I was accepted to Hanyang University in 1977, you became freshmen in 2017, and I’m given 7 minutes to lecture.” (Laughs) “Steve Jobs once said that he was standing on the crosspoint of technology and humanity, because technology cannot satisfy the human heart. A quote from a poem by the Korean poet, Ko Un, goes: ‘I saw that flower coming down the hill. One that I hadn’t, coming up the hill.’ Concentrate on humans in the future that you create. Concentrate on little things like flowers. Congratulations.” Next, Hanyang University’s president Lee Young-moo gave an inspiring speech to encourage the new students and lead them onto their academic path.

In this technological era, we can use our knowledge and technology to volunteer and bring love and help to others. The 4th Industrial Revolution is close at hand. In 2021 - when you graduate - there will be even grander changes. Adapt your paths for the future.” Another priceless corner prepared by the ceremony was the “Moving Story Speech”. A freshman from the Department of Mechanical Engineering, Choi Hye-min talked about her volunteering experience at high school. She has successfully fundraised and donated 150 million won to help out the victims of the 2015 Nepal earthquake incident. Choi Hye-min (Department of Mechanical Engineering) "My life motto is: 'Everyone in this world should be happy'." “My high school and a Nepali school had set up a sisterhood agreement. We have shared precious memories together with our Nepali friends. When I heard that an earthquake occurred in Nepal, I suddenly thought of my friends and searched for ways to help them out. As a representative for high school students, I stood at the 300 Round Table Debate hosted by the Chungnam Office of Education and successfully persuaded them to donate.” “Whether it's volunteering or studying, or even drinking and hanging out, I want to do my best.” After a few more speeches, the Hanyang Entrance Ceremony Organizer team and the Hanyang Dance Leader team introduced themselves and showed off their hard work built up during the past few months.
