'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 email@example.com Photos by Kim Youn-soo

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.

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.

With computers today, auditory and visual senses can be materialized—through sound and screens. The other three of the five senses, on the other hand, have not yet been on the platform of materialization because they require a somewhat more delicate mechanism and are harder to deliver with technology. Professor Park Wan-jun (Department of Electronic Engineering), in his paper, “A tactile sensor using single layer graphene for surface texture recognition”, presented and elaborated on a tactile sensor that could distinguish different materials, which opens many doors for future technology. It is hard to imagine the sense of touch being delivered with a machine because it is usually perceived as something only humans are capable of. But why can sound and sight be materialized by computers but not touch? The answer is, electronic signals for sound and vision are made possible in the aspect of engineering, while that of touch is not. What Park presented in his paper is a small chip-like device that enables perception of touch for surface texture recognition. The output of Park's research, which is a chip-like electronic device. (Photo courtesy of Park) The first thing he had to do, according to Park, was to turn the sense into electronic signals. Only then can the machine read what is being conveyed. Once the signal of touch is conveyed to the device, it will analyze the signal and distinguish what kind of texture it is. The subtle and clear differences in terms of texture between various kinds of surfaces can be perceived and distinguished by the tactile sensor, detecting the microscopic scale of differences. There is a single layer of graphene embedded in the device, which creates a different resistance variation each time a surface comes to interaction. It is what functions as the main player in telling apart different surfaces because it is what creates the different signals. The signal is then sent to the computer by the chip, which is to be analyzed and categorized into different kinds of textures. “Just as there is virtual reality (VR) for sight, a touch-version will be possible with this device,” anticipated Park. “A tactile display is also possible with this device, as the signal for touch is now readable by the computer. If you put your hand on the tactile display device, you can actually feel whatever the object or texture input in the computer is,” envisaged Park. This technology is also applicable in the medical field. Those who lost their sense of touch in certain parts of their body by burns, for example, will be able to regain their sense by implanting this small device in the portion of injury. Now that the signals of touch can be read by the device and since senses can be transmitted in the form of signals, delivery of the sense of touch is made possible. The inserted chip will send signals to the brain and this will enable the patient to feel what is being touched. “In recap, this research of mine has provided a human-sensorlike device that will enable transmission of the sense of touch in terms of engineering. Now I’m currently working on machine learning by categorizing and classifying different textures into groups and making the device absorb the data. The ultimate goal of my research is to complete materializing the sense of touch from the perspective of engineering so that further technologies could be developed based on my research,” planned Park. Park's further research is set on mechanizing the sense touch. Jeon Chae-yun firstname.lastname@example.org Photos by Choi Min-ju
With a strong sound of the timpani, the 2017 Hanyang Wind Orchestra raised its curtain on Sunday, September 17. Wind Orchestra is named after the characteristics of the instruments used in the performance. Wind instruments such as the flute, oboe and clarinet fill most of the stage with percussion and some string instruments. “Wind Orchestra can fulfill both artistic and public needs in music as percussion and wind instruments create dynamic sounds.” Said Park Min-ji, from the Department of String & Wind Intsruments. Members of the Wind Orchestra, collaborator Lim Jae-woong (Department of String & Wind Intsruments, 4th year) and conductor Kim Eung-du (Adjunct professor, Department of String & Wind Intsruments) are on stage for the rehearsal. Pieces with diverse emotions Dynamica written by Jan Van der Roost was the first song to welcome the audience with a bright and powerful mood. The piece instantly filled the KBS hall in Yeouido with joy and glee, making the audience anticipate the next number. The song then turned into another phase where it instantly changed the whole atmosphere. Minor codes running off fast imposed a nervous feeling, as if the orchestra was being chased by something. Concertino da camera introduced one of the stars of the night, Lim Jae-woong (Department of String & Wind Intsruments, 4th year). Lim played fast and complicated notes with a saxophone and made it look so easy, almost without a blink. As the main collaborator, Lim competed against more than 10 students for the spotlight. “It sounded like an OST from a TV soap opera. The grand music was almost overwhelming” said Lee ye-rim (10), daughter of an anonymous graduate from the Department of Urban Planning. “We came to see one of our old friends, and decided to take our kids for educational purposes.” The Lee family is taking a photo at KBS hall during the intermission. Lee Ye-rim (10) in the top middle and the anonymous alumni, far right. The following piece, Angels in the Architecture presents a somewhat unfamiliar instrument called ‘whirlies’. This instrument creates a beautiful wind sound that falls perfectly with the soprano’s voice (featuring as ‘angel’) and the title of the song. The composer Frank Ticheli noted that the whirlies are supposed to represent the halo of the angel, too. Irmak Akoglu, an exchange student majoring in biomedical engineering revealed that this is her first time at an orchestral performance, and said, “the songs they chose were amazing. It gave me so many different emotions." University of Texas Wind Ensemble is performing Angels in the Architecture with the composer and conductor, Frank Ticheli.

(Photo courtesy of The University of Texas Band) An interactive performance After the 15 minute intermission, four songs were given: Lento, Scherzo, Mesto and Allegro Giocoso as part of the Third Symphony. Then, loud applause broke out for a long time, long enough for the conductor Kim to introduce every member of the orchestra. "Encore!” “Bravo!” as several audience members shouted out their excitement. Part of the brochure of the 2017 Hanyang Wind Orchestra. (Photo courtesy of College of Music) Two encore songs followed, including Hanyang’s official school song. The first one was absolutely the most impressive encore of all time. Conductor Kim held a microphone and showed gratitude for all the people who came to see the performance, and he excitedly went on to say, “I want to take you all to an amusement park. If I give you a sign, please scream for 30 seconds as you are riding a rollercoaster. Please do scream out loud as much as the lights can fall out from the ceiling!” The performers moved their body back and forth while playing the instruments to truly bring out the mood for the audience and when Kim signed, they raised their arms and screamed enthusiastically. Along with ovation that again lasted for a long time, this year’s Hanyang Wind Orchestra closed its curtain. "All seats of the performance are free of charge and based on invitation every year to enlarge the opportunities for Hanyang students and faculty members so that they can be exposed in this unique form of orchestra,” said Park. If you have missed this year’s show, there still is a chance soon on November 2, as the orchestra was invited to a college orchestra festival. Kim So-yun email@example.com Photos by Park Young-min
