[Infographics]2019 Fall Semester: ERICA Students by the Numbers

According to the ERICA Campus enrolled students report on the current state for the second semester of 2019, compiled on October 1st, the number of students enrolled in the school year stood at 8,657 and 3,593. If the 445 students who postponed acquiring their bachelor's degrees is distinguished and taken into account from this year's statistics, the total number of enrolled students will be 12,695. The figure was down 433 from 13,128 in the statistics from the first semester (as of April 1st). According to the colleges and universities category, students enrolled in Engineering Sciences was the highest with 2,938 students, while the lowest number of students was in the College of Pharmacy with 128 undergraduates. However, in terms of the ratio of students to those who are enrolled, the College of Pharmacy shows a 98 percent enrollment rate as a result of only having two students on leave of absence. The College of Communications placed the second highest on the ratio of students attending school with 71.9 percent, and the College of Science and Convergence Technology scored the lowest with 63.5 percent. The gender ratio of the enrolled students was 4,916 males and 3,741 females out of the total 8657, creating ratio of 57:43, and the school year dispersion was evenly distributed by 25% without any major deviation. However, the distribution of students on leave of absence was slightly different. Among the total of 3,593 students, the gender ratio of the students on leave was 77:23 with 2,764 males and 829 females, followed by the school year distribution ratio of second grade (38.4%), third grade (28.2%), fourth grade (20%), and first grade (13.1%). Among the 445 students who postponed acquiring their bachelor’s degree, 434 students did not register for courses while 11 students did, making it 3.5% among all enrolled students. By unit, the College of Languages & Cultures had the largest number of students with 125, with the exception of the College of Pharmacy, the College of Sports and Arts had the lowest number of students with just 5 students. Meanwhile, 98 students were expelled in the first half of last year (March 1 - August 31), and 15 students were expelled due to the expiration of their leave of absence due to employment, taking up the majority. The number of graduates was 603 based on late 2018 graduates. The Hanyang Global News Team - Global@hanyang.ac.kr *Special Translation by: Kim Hyun-soo

[Special]Group Projects in Korea?

Team projects in Korea, widely known as "teample (팀플)" in Korean, are notorious for the many types of people you’ll encounter. Let’s take a look at the different types of people in a team project here in Korea, as commonly depicted on SNS for humor purposes, and from the experiences of foreign students’ attending Hanyang University in order to gain a deeper insight into what team projects are like for those from different cultures and backgrounds. A picture describing the different possible types of people in a group project. (Photo courtesy of 9gag.com) A photo that implies that the work distribution among team members is not always fair. (Photo courtesy of quickmeme.com) Some of the different possible types of people in a team project include the Googler type, a person in charge of doing the data research but does the minimal amount of work and easily gets it done on Google. The Always Dissatisfied type who complains about everything that the other team members are up to, without suggesting a solid solution. The so-called, Gold Hands type who excels at creating valuable presentation materials and are usually exceptional at using computer programs. The Loudmouth type is great at speaking, but whether they are great workers, remains unknown until the work is done. Then, of course, there is the Doesn’t Read Text type who avoids reading text messages related to the group project. In Korea, there are also those Seniors Preparing for Employment type, an individual who does not take the team project seriously and is too busy getting ready for their employment at a company. Nurul Fatini Binti Mokhtar (Department of Mechanical Engineering, 1st year) shared her team project experience in a course called Introduction to Engineering Design. She and her Malaysian friend were teamed up with three other Korean students, and they were required to build a drone as a team. “A team project requires smooth communication, and being on a team with a foreigner means that communication will be a barrier to overcome,” she said. “I felt a sense of rejection due to the language barrier, which held me back from reaching out to people.” Fortunately, Mokhtar had welcoming group members. The leader of the group was the “loudmouth type” who made everyone feel comfortable and led the group in getting things done with his communication skills. She also met the Googler type who used google to ease the communication barrier within the team. For her, the team project in Korea was a novel experience. She appreciated that she had a chance to communicate with Koreans and get to know them better, but felt that the limitations of group projects lie in the difficulty between discerning the line between genuine interest in being friends or just mere group teammates, she said. “I wish team projects could hold more depth in the creation of a bond between members.” Arauca Lozito (Department of Media and Communication, 4th year) described team projects in Korea as, agonizing. She has been attending Hanyang University for almost four years. Lozito pointed out that the language barrier was an impediment in expressing her own ideas in front of Korean students. Besides the difficulty in smoothly delivering one’s ideas, the different perspectives that come from varying cultural backgrounds contributed to misunderstandings and differences in ideas. She criticized the process in that, usually, the group leaders have an awful amount of burden, as they implicitly hold the role of assigning individual roles and taking charge of everyone in the group. Claudia Sarai Moreno Flores (Department of Electronic Engineering, 4th year) agreed, and shared her impression of team projects in Korea being run by one or just a few people doing most of the work. She said she has seen the Loudmouth type who speaks more than working, the Gold Hands type who is excellent at creating elaborate PPTs, and the "I came here to play” type, who lived by the “all play, no work” principle in her laboratory classes regarding circuit theory, logical design, and chemistry. Julia Bärlund (Business Administration, 4th year) commented on the different types of people during group projects. Being a business major, she seems to always notice the one who has done a similar project before and takes the lead, the one who does a ton of research by just copying and pasting to a word file, and the free riders. By half a chance, she usually encounters a member who is preparing for employment and can be seen only two times during the semester, but that they usually still know what they are doing! She described the Korean team projects as strategic and logical, being all about getting things done. "Koreans are effective and dynamic -- which I love." Team projects are what university students must go through regardless of where they are, but the group projects that foreign students at Hanyang University seem to point out some distinct difficulties that they have faced as well as the characteristics of the Korean “team project culture.” Most notably, for foreign students who are not used to Korean culture, the responsibility remains on the Korean students to ease the language barrier and derive cooperation from all members. As Lozito said, “we all think differently, but that doesn't mean you're wrong.” Although team projects are difficult, in that, people with colorful, distinctive ideas must come together to achieve one objective, it gives us a great lesson in cooperation along the way.

[Special]The National Public Official Examination, Hanyang, and Korea

In October, Hanyang University congratulated 14 students for passing the Rank 5 National Public Official Open Competitive Examination for service in technical post. Placards all around the campus proudly state that out of a total 66 final successful candidates, Hanyang produced the second most number of candidates, right after Seoul National University. So what exactly is this Rank 5 National Public Official Open Competitive Examination, and why is it such applaudable news at Hanyang, not to mention in Korea? In June of 2019, a survey of Korean middle-school students showed that the number one dream profession of children was not that of an actor, teacher, or athlete, as it used to be in the past, but a public official. This is said to be due to the harsh pressure that the young generation is undergoing, under the circumstance that getting a decent job these days is not an easy task. It is the same with the university students, and this is reflected in the number of applicants for the public official examination, which has doubled over the past five years. Although an individual’s reason may differ, the prime reason for this is the job's stability and economic security in older age. For such realistic desires, the public official has become the ‘dream job’ in Korea. Naturally, competition is fierce. To become an official, one needs to pass a series of notorious tests. Public officials in general service in Korea are ranked from 1 (highest) to 9 (lowest), and there are various examinations for different ranks and subfields, each with their own specialized tests. The most well-known examinations are Rank 5, Rank 7, and Rank 9 National Public Official Open Competitive Examinations (the aforementioned examination for service in technical post is a subfield of the Rank 5 examination). The competition rate for each has been high every year, and this year, the rate for Rank 5, 7, and 9 recorded 36.4:1 (13,478:370), 46.4:1 (35,238:760), and 40.9:1 (202,978:4,953), respectively. The intense competition and notorious test levels necessitate years of intense studying. Im Su-yeon (Department of Electronic Engineering, 4th year), one of the successful candidates this year, explained that it is common to take about three years of hard work to pass the test. This year, she studied nine hours a day and six days a week. The intense competition and notorious test levels required of applicants average approximately three years of intense studying. Hanyang's examination preparation class (고시반, gosiban) is where students spend most of their time in the studyroom provided by the university. (Photo courtesy of Public Official Examination Class for service in technical post) Despite the difficulties, many students of Hanyang achieve their dream each year, and Hanyang has produced many successful public officials in many fields. Most notably, the results of the Rank 5 National Examination for service in technical post has been exceptional each year. Since 2011, there are on average 12 successful candidates each year, and in 2016 and 2017, Hanyang ranked first and second with 19 and 15 candidates, respectively. Behind this is effort is a tremendous amount of support from the university in the form of a Public Official Examination Class (고시반, gosiban). A gosiban is a class for students who are applying for a national examination. Students who join the class usually stay in the school dormitory, sleeping, studying, and preparing together and receiving various support from the school. Hanyang University supports many classes for each Public Official Examination, including ones for the Rank 5 examination in administration and the National Diplomat Candidate Test. The class for service in technical post is one of them, which accepts and maintain about 80 students each year. Students receive much financial and educational support, such as provisions for a dormitory, tuition, food expenses, study rooms, and lectures. Students of gosiban are studying in a seminar room. Even at this very moment, Hanyang students of gosiban are studying at their desks for their future as a public official of Korea. The head professor of the class for service in technical post, Lee Ju (Department of Electrical Engineering) stated, “although it requires harsh preparation and endurance, it is a path definitely worth trying. Even if you do not pass the test, the years of studying will make you a competent engineer. Also, it is a great opening to a grand mission of running our country yourself.” Lim Ji-woo il04131@hanyang.ac.kr Edit by Kim Ju-eun

[Special]The Day of Cultural Activities

In Korea, the last Wednesday of each month is, by law, designated as a "day of cultural activities." In order to lower the threshold of cultural facilties across the country and spread the cultural flavor in people's lives, the Cultural Promotion Committee and the Ministry of Culture, Sports, and Tourism initiated the policy of cultural day from January of 2014. On this day, cultural activities provided by more than 2000 cultural facilities including movie theaters, performance theaters, museums, art museums, and cultural properties can be enjoyed for a discounted price, or even for free. Some facilities even extend their opening hours on this day so that office workers can take advantage of this special day after their work. The last Wednesday of each month in Korea is designated as a "day of cultural activities." (Photo courtesy of culture.go.kr) Major movie theaters in Korea, including CGV, Lotte Cinema, and Megabox engage in price discount of 5,000 won for movie tickets from 5pm to 9pm. For those who prefer to watch more lively performances such as plays, musicals, or dance perfomances, there will be discounts or special programs available on the last Wednesday of each month. As for fine arts and exhibitions, major exhibition facilities, including the National Museum of Contemporary Art will either be free, discounted, or even opened for extended hours. In libraries for book lovers, special programs may be enjoyed. The palaces in the city, such as the Gyeongbokgung Palace, the Changdeokgung Palace, the Changgyeonggung Palace, the Deoksugung Palace, the Jongmyo Shrine, and the Royal Tombs of the Joseon Dynasty are also on the list. They are open for visitors with no extra cost once a month. The Gyeongbokgung Palace, located in Jongno-gu, is free of charge on the last Wednesday of every month. (Photo courtesy of korean.visitseoul.net) For Hanyang University students, cultural day can be enjoyed near campus in Seongdong-gu. On the last Wednesday of November, the CGV movie theater near Wangsimni station offers 2D movies for 5,000 won from 5pm to 9pm. At the Galeria Foret, an exhibition titled Brick Campus in Seoul features art made of brick or even legos, while the other exhibit in the Galeria Foret, titled The Muse; Degas to Gaudi, can both be visited for a discounted price on the spot. The Seongdong public libraries are offering a tempting deal by allowing people to borrow up to 10 books. Besides offering people various opportunities to experience cultural activities, the Ministry of Culture, Sports and Tourism engages in diverse, designed businesses for the purpose of cooperating with private organizations and expanding the cultural leisure of citizens. These ongoing projects include a local culture content characterization business, with the aim of excavating culture programs using intrinsic local culture and the “youth mike” which supports youth by supporting their dreams of becoming professional musicians by providing the opportunity to perform on stage. Culture day is the day to take a “break from our daily lives,” as its slogan suggests. Why don’t we take the last Wednesday of every month to enjoy the diverse cultural experiences open to us in Korea and fill ourselves with energy to go on with our daily lives? Culture day offers us just what we need in this complicated modern world. The relaxation and enjoyment, ensued by the fresh energy to start out a new month, awaits you.

[Special][magazine] Hanyang News Through Email

Hanyang University sends email newsletters introducing representative issues and research achievements to 11,000 researchers abroad. Does a chef serving a nice dish feel the same as we do? After sending a newsletter to a number of researchers worldwide, the editor is both hopeful and worried. Thoughts of how to better introduce Hanyang University, worries about making the readers feel uncomfortable, and wishes of building close relationships are intertwined. Monthly newsletters are the result of a lot of sincerity and effort. We hope that the new betterments of the Hanyang University email newsletter can reach out to more people. Writer : Manager Kim Sang-oh (PLANNING AND EVALUATION TEAM, OFFICE OF PLANNING) The Fundamentals of Email : Think Once More from Users Point of View The email can be perceived by some as simply an old-fashioned means of communication. However, and at the same time, it is also the best and most standardized way of communicating. It is hard, however, to think that the objective of the email is achieved after just sending emails unilaterally. In fact, the user’s perspective must be considered. Will users even open the email? How will they evaluate and react when they click on the email? Will they feel no objections and simply click to obtain more information? Questions such as these were the first considerations in improving the email process, and issues of these types were carefully examined. We made changes in the way that basic information is delivered in an email by placing only the right amount of text so that basic information is delivered without any additional clicks. Additionally, we carefully reviewed and organized the procedures for presenting concise and interesting issues, along with easy to connect information. The overall arrangement of content, eye-flow, and unobtrusive design were all considered one by one. Themed Content for the Intro: Different Features each Month The biggest change in content is in the introduction. Breaking from the previous simple structure where research achievements were written in parallel form, the front page is now reserved for an article that will leave a strong impact on the readers. This content is structured with Hanyang’s core strengths ‘3S Strategy (Smart Education & Research, Start-Up, Social Innovation) and Industry-University Cooperation’ in order to increase its impact, leading readers right to the main content without unnecessary detractions. ** 3S: Smart Education & Research, Start up, Social Innovation The first topic was “Smart Education.” It introduced Hanyang’s unique IC-PBL program which is leading the future of education, along with example cases. The next topic was “Smart Research,” and it introduced eight researchers whose work is related to the Fourth Industrial Revolution. The results were expected to interest researchers across the globe who are unfamiliar with Hanyang University. The next topic will be “Industry Academia” and will describe ERICA Campus’ University-Research-Industry cooperation achievements and how the new major of “Social Innovation” is helping Hanyang University to lead in the field of social innovation. For such articles, different staff members from the related departments with in-depth knowledge of the programs will join as writing staff so that the articles can be more precise and impactful. This process of showcasing articles with different themes each month will help deliver Hanyang’s unique strengths clearly. Considering User Interface: Small Change, much Satisfaction The changes in design are also considerable. The new newsletter was made in a responsive page type to overcome technological limitations since the previous one did not take various user interfaces into consideration. Thus, simple content arrangement is favored over detailed design. Readability for users, whether through PC or mobile, is given the highest consideration. Emails have become easier to read since many unnecessary images were removed, making the content more streamlined. A review of email reception showed that 43% were viewed on desktop, 27% were viewed on mobile, and 25% were viewed on unknown devices. Considering app-based user trends such as Gmail (Google), the actual mobile environment is expected to be around 50%, and this number is expected to rise. Reasons to consider user interface are also supported by the numbers. [Graph Embedded] Please insert the data in a pie chart - Desktop 43%, Mobile 27%, Unknown 25%, Others 5% - Caption: Data on Email Recipients’ Viewing Methods for October 2019 [Image Embedded] (1) An image of a previous newsletter (2) An image of a new letter (3) An image of a new mobile letter Close Observation and Reaction Based on Statistics: “Meticulous Review After Sending Email” Just sending a newsletter is not enough. A variety of supporting data has shown that recipients’ situations and responses can be used to identify and address issues that should be considered for future installments. With the newly introduced platform, it has become possible to gather statistical data such as the “open-rate (the rate of people who opened the email),” which links were the most favored, in what environment people opened the email, and to what extent action was taken in response to the email. The improvements now allow us to better understand the readers’ minds after analyzing and processing the data. This month’s email will feel more comfortable than last month’s email. These days, universities are continually innovating for their survival in the face of crises such as changes in the international higher education environment due to the advent of the Fourth Industrial Revolution, educational platforms that include MOOC (Massive Open Online Courses), and the sudden decrease in the number of students. In addition to further strengthening the university’s specialties in areas such as education and research, the university is also promoting a number of changes in areas such as university-industry cooperation, start-ups, and social innovation. Universities also need a process of demonstrating their achievements effectively and gain recognition. Considering various domestic and international university evaluations, managing the reputation of the university has been an important mission. In this situation, the improvements and reformations of the newsletter were not a choice but a necessity, and Hanyang University will advance without hesitating on the verge of such changes. If you want to receive a special email of unique Hanyang features once a month, please follow the links below.

[Special]Stories of Old Rulers, the Tailoring Tool

'Bang Won Pyeong Jik,' which means Bang (方) for Square, Won (圓) for Circle, Pyeong (平) for Horizontal, and Jik (直) for Vertical, is a term describing a fundamental architectural principle -- that a building should be a proper harmony of a square, circle, horizontal, and vertical. The term is also the title of the collaborative exhibition by the Hanyang University Museum and Hanyang's Far East Architectural History Lab. The exhibition's full title, ‘Bang Won Pyeong Jik: Tailoring the houses’ is currently being held at the Hanyang University Museum from October 10th to the 31st. As its title indicates, the main theme of the exhibition is the tool which forms the basis of all architecting and tailoring, the ruler. The exhibition holds significance as it commemorates the 80th anniversary of Hanyang University as well as the Department of Architecture, the major that has been with the school from its establishment. The exhibition, ‘Bang Won Pyeong Jik: Tailoring the houses’ is open from October 10th to October 31st, 2019. The exhibition presents a wide collection of rulers used by architectural artisans from ancient times to present, from Eastern to Western. Rulers of great cultural value can be seen at the exhibiton, including an old dangcheok (a ruler used in the Tang dynasity), rulers used in ancient Korea from the Goryeo and Joseon dynasties, as well as a nine-meter ruler of Shin Eung-su, the master carpenter of Korea, whose ruler was used for the repair of Seoul’s Gwanghwamun. The exhibition also tells many interesting facts about rulers, such as interpreting dreams about a ruler, how the standards of measuring have changed over time, how kings of the past tried to ‘rule’ through rulers, and even a picture of how tall Kwanwoo, a nine-cheok human from the Records of the Three Kindgoms, actually was. By showing the meaning and the value which rulers have held throughout history, the exhibition invites its visitors to realize the significance of a mundane tool -- the ruler. The exhibition displays a wide collection of rulers used by architectural artisans from ancient times to present, from Eastern to Western, based on the theme of Bang Won Pyeong Jik. Professor Han dong-soo (Department of Architecture), the head of the Far East Architectural History Lab, explained that the idea for the exhibition came from a simple proposition he once made to one of his students. “There was a student who did not have a hobby, so one day I recommended him to try and collect rulers. After two years, he had gathered about 200 rulers. It felt like a waste to not put them on display,” said Han. “The ruler is the first tool to be used for any work, whether it be for tailoring clothes or building a house. Thus, it holds something special for architects." Professor Han dong-soo (Department of Architecture) and his students in Hanyang’s Far East Architectural History Lab proposed the idea for the exhibition. The exhibition, which is free of charge, will be held until October 31st, 2019. For its visitors, Han has encouraged us to think about the history and the wisdom behind the mundane tool called the ruler. “Throughout history, rulers have played an important role, far more than just measuring. They encapsulate the wisdom of the past architects, even as far as embodying the absolute power of a kingdom. It will be of much fun to consider these aspects with your visit," said Han.

[Special][HYU High] 8 Representative Hanyang Researchers, Leading the 4th Industrial Revolution

The era of technological revolution is changing at a frightening pace! Where is university research heading in the days of the 4th Industrial Revolution? What is the secret to Hanyang’s outstanding research that has been leading the era of the 4th Industrial Revolution? The answer can be found in Hanyang’s 80-year history. For the past 80 years, beginning in 1939 when Hanyang University launched its education program based on the founder’s idea of “making the nation rich and strong through technology education,” that idea has continued through the university’s educational philosophy of offering “practical academics.” Hanyang University has always supported research and education that help society and the nation, and this has gained even more significance in the era of the 4th Industrial Revolution. The following eight representative researchers and their astonishing research results show how Hanyang University is leading the era of the 4th Industrial Revolution. Professor Kim Ki-hyun, Civil and Environmental Engineering Developed technology that eliminates air pollution-causing matter Professor Kim Ki-hyun has developed a new material related to improving the environmental analysis system that controls and manages Volatile Organic Compounds (VOC) and bad smells. Benzene and formaldehyde are kinds of VOCs, which are class one carcinogens that can be produced in daily life when people cook, drive, or smoke. Current air purification technology has limitations in detecting and eliminating such carcinogens, since they only specialize in dust elimination. Combining metal and carbon organic matter, Professor Kim developed Metal Organic Frameworks (MOF) and succeeded in adsorbing and eliminating such pollution particles. In addition, he simultaneously developed technology that effectively concentrates samples, such as toxic substances, and suggested a new air quality diagnosis method that analyses 22 kinds of odor causing materials which have been designated by the Ministry of Environment. Professor Kim Sang-wook, Computer Science Developed big data graph analyzing technology which is 40 times faster than the current method Professor Kim developed a single-machine-based graph engine called RealGraph, which has big data analysis capabilities 40 times faster than that of current technology. While planning RealGraph, he used the phenomenon that “real world graph data shows power-law degree distribution, not normal distribution.” (An example of the power-law degree is how on Instagram most users communicate with a small number of other users, while very few users communicate with a large number of users.) Existing graph engines did not consider power-law degree distribution which caused uneven workload distribution and inefficient memory access, but Professor Kim applied new strategies to solve those problems. As a result, RealGraph performed up to 44 times faster than existing engines when processing large-scale graph big data. His engine is expected to be utilized in various fields such as social media analysis and protein structure analysis, due to its fast analyzing capacity. Professor Kim Seon-jeong, Electrical and Biomedical Engineering Artificial Muscle, 40 times stronger than human muscle Professor Kim Seon-Jeong, together with an international research team including researchers from the University of Texas, developed a new “sheath-run” artificial muscle that is 40 times stronger than human muscle. This newly developed sheath-run artificial muscle has 9 times higher performance than the original artificial muscle, and it was able to solve the economic problem which has been seen as a limitation of existing artificial muscles. Since it no longer uses carbon nanotubes which have a high manufacturing price, and instead uses commercial threads such as nylon and silk, the newly developed technology has a lower material price and thus a much higher commercial value. Professor Sun Yang-kook, Energy Engineering Developed a cost-effective, high capacity electronic battery The main field of research for Professor Sun Yang-kook is cathode materials for lithium-ion batteries and next-generation battery materials. Cathode materials for lithium-ion batteries are a crucial key to solving some critical issues related to electric cars - short driving distance and high cost. In the manufacturing of electric cars, 60% of the total cost is for materials, 44% of which is spent on cathode materials. Therefore, the price of electric cars could be made more affordable if one could lower the price of cathode materials. Using more nickel would help to lower the price and increase the battery capacity, but then stability and battery life would underperform due to increased heat. That is, battery capacity and battery stability and life are in inverse proportions. Professor Sun developed a Full Concentration Gradient Structure cathode material (with increased nickel content in the center and increased manganese content at the surface) to solve the issue. Cheap and stable cathode materials with large capacities can now be manufactured, and these are being used in Kia Motors’ electric vehicle, the Niro EV. Professor Sunwoo Myung-ho, Automotive Engineering Developed an autonomous vehicle Professor Sunwoo Myung-ho is a world-class leader in the field of autonomous vehicles. Last March, professor Sunwoo succeeded in operating a 5G based urban, self-driving automobile for the first time in the world with LG U+. It was the first time that a 5G self-driving car succeeded in driving autonomously through congested urban roads full of vehicles. The key to the autonomous vehicle that his team developed are the high-end sensors and deep-learning-based AI. In fact, sensors such as Lidar, Radar, and cameras recognize the nearby environment, and the AI technology drives and responds to lane changes in the front, rear, and sides of other vehicles. Because corresponding AI technology is based on deep learning, it continuously accumulates and analyzes data such as driving on roads, situations, and variables and continues to evolve on its own. Professor Sung Tae-hyun, Electrical and Biomedical Engineering Enhancement of energy harvesting technology to change waste energy into electricity Energy Harvesting technology, which is the primary research of professor Sung Tae-hyun , is a method using an independent source of current for sensors by converting the light energy of fluorescent light and vibration energy that are being discarded at industrial sites into electric energy. There are various Internet of Things (IoT) sensors on the industrial site. Most are supplied with electricity by wire, which makes the installation site limited. If an energy harvester, used as an independent source of power for sensors, is created, products that utilize IoT sensors can be built in various places. The energy harvesting technology of Professor Sung Tae-hyun’s research team is the world's best. In particular, the Piezoelectric Energy Harvesting technology, effective in converting vibration energy into electrical energy, is most prominent. Additionally, professor Sung stated, “Hanyang university possesses the record of 9.38 mW/cm2, which is 16 times the previous world’s highest value of 0.58 mW/cm2 (previously held by Shanghai Jiao Tong University), and we are reaching for 12 mW/cm2 through this research.” Professor Lee Young-moo, Energy Engineering Developed technology that drops the price of hydrogen fuel cell to 1/10 Professor Lee Young-moo is an expert of polymer engineering, including a separator, carbon dioxide separation, fuel cells, and polymer materials. He is also famous for serving as the 14th president of Hanyang University while also continuing his research and even publishing in the Scientific Reports Journal ‘Nature’ during his tenure as president of Hanyang. He developed a hydrogen fuel cell separator, which imitates the moisture retention function of cacti. This technology is expected to lower not only environmental pollution but also the price of electric cars that use hydrogen fuel cells. Hydrogen fuel cells obtain energy through chemical reactions occurring in multiple layers of electrolyte membranes. However, existing electrolyte membranes have a limitation in performance at high temperatures and an inability to maintain moisture for chemical reactions. Professor Lee solved this problem by developing a new membrane modeled after a cactus. With this technology, the hydrogen fuel cell can be made at one-tenth of the existing price, ultimately reducing the price of hydrogen cars by up to 30%. Professor Jang Joon-hyuk, Electronic Engineering Developed a voice recognition technology based on artificial intelligence Professor Jang Joon-hyuk developed ‘Pluto,’ the first embedded AI speaker in Korea that can recognize voices without connecting to the internet. The existing AI speakers produced by domestic IT companies needed to be connected to a cloud server for voice recognition causing a network delay and security issues in the process. Professor Jang solved this problem by applying an embedded method that incorporates a large voice recognition system with a capacity of 200,000 words into the hardware system. To facilitate voice recognition in a long-distance environment, he developed a ‘beamforming’ technology that eliminates noise for smooth, long-distance voice recognition and a ‘speaker recognition technology’ that only recognizes registered user voices and filters any voices coming from the TV. He also conducted university-industry cooperation with global IT companies with such original technologies. Professor Jang is continuously developing voice recognition technology that can control every device with only one’s voice similar to his other completed technologies like Bixby of Samsung, AI car doctor and voice recognition engine of Hyundai Motors, Q Voice of LG, and ‘Chloe,’ an Incheon International Airport guide robot. * The list of researchers follows the (Korean) alphabetical order.
