When a new phone launches, one can visibly notice that one of the main improvements are longer battery life with a faster charging speed. Needless to say, batteries are a crucial part of an electronic device and there are continuous developments made in order to increase their efficiency. Likewise, Professor Park Won-il (Division of Materials Science and Engineering) carried out experiments and research on the negative electrodes of lithium-ion batteries to improve the efficiency of battery charging. Along with various others, Park wrote a thesis with the title “Controlling electric potential to inhibit solid-electrolyte interphase formation on nanowire anodes for ultra fast lithium-ion batteries.” Professor Park Won-il (Division of Materials Science and Engineering) talks about how the experiments were carried out on the lithium-ion batteries. The lithium-ion battery is well-known as it is included in most wireless devices such as electric cars. The lithium-ion battery contains both a cathode, which is the positively charged electrode for batteries and an anode electrolyte, a negatively charged electrode. Park’s research was focused on the materials of the anode electrolyte. When a battery is running, a potential drop occurs between the cathode and electrolyte anode. Due to this drop, a solid-electrolyte interphase layer forms on the active material surface. Park focused on researching the active material that goes in the anode electrolyte in order to increase battery charging efficiency. Originally, the basic material utilized was graphite, which has the capacity of 360 mAh/g (milliampere hours per gram). However, to follow the demand of a higher capacity material, Park decided to implement Nickel Silicide, the capacity of which is 1300 mAh/g, four times that of graphite. Figure C shows how Nickel Silicide (NiSi) was utilized in order to inhibit solid-electrolyte interphase. (Photo Courtesy of Park) In the thesis, a three-dimensional macro graphite nano tube model to control the electric potential and prevent solid-electrolyte interphase utilizing Nickel Silicide was introduced. Solid-electrolyte interphase occurs when the potential drop, established between cathode and anode, drives to decompose the electrolyte and form a solid-electrolyte interphase layer. This enabled the potential drop to take place on the potential sheath instead of the active material surface. After countless experiments, up to two thousand, utilizing Nickel Silicide showed outstanding performance under 20C, taking less than a minute to fully charge. The capacity of a battery is generally rated at 1C, which means that it takes one hour to fully charge. (From left) Chang Won-jun (Division of Materials Science and Engineering, '16) and Professor Park Won-il (Division of Materials Science and Engineering) mentioned that the experiment was carried out more than two thousand times. When asked how long it took to complete the experiments, Chang Won-jun (Division of Materials Science and Engineering, ’16), who led the majority of experiments, said that they began in June of 2017, and their thesis submission and revision started at the end of December that year. Although the repetitive experiment proved that the performance of lithium-ion batteries utilizing Nickel Silicide was outstanding, deriving the precise evidence proving that solid-electrolyte interphase took place outside the surface was the task that took seven to eight months. Park concluded more research is still needed. In the current state, it will take more time for the newly developed structure to work. However, he hopes for the concept to be utilized on the betterment of lithium-ion batteries and become a breakthrough for battery charging in the future.

In Korea, students are often told from an early age that once they get into college, they will be able to do anything you want. They can find a girlfriend or a boyfriend, become more beautiful or handsome, and find a job and proceed with their life to get married and live happily. Parents make it sound as if life after university is filled with flowers and chocolate. Unfortunately, however, the story is not always the case. Soon after students get into college, reality hits them in the face with various exams, projects, job seeking, relationship problems and more. Filled with concerns and stress, some students are met with their dillemma of whether to move on to the graduate school or not. For these students, paying a visit to the annual Hanyang University (HYU) Graduate School Fair is highly recommended. 2018 Fall HYU Graduate School Fair held in the Olympic Gymnasium. 2018 Fall HYU Graduate School Fair was held on October 4th for Seoul campus and on October 1st and 2nd for ERICA campus. According to Han Kang-min, the leader of HYU graduate school team, the graduate school fair has been held since the spring of 2015. For the Seoul campus, the fair consisted of three main corners: one on one consultation for all 64 participating majors, 55 lab tours for 15 majors, and a 50 percent discount for those who are registering on-site. For ERICA campus, there were 33 participating majors with 73 lab tours from 10 majors. “Despite the decreasing number of graduate school students all around the country, HYU has around 2225 graduate students. We started hosting this fair because we wanted to offer our students with helpful experience and better flow of information, especially since the registration period is coming up,” said Han. Jeong Young-woon (Department of Electronic Engineering, 2nd year graduate) (left) and Lee Jun-ho (Department of Electronic Engineering, 2nd year graduate) (right) are explaining about being a graduate school student of the Department of Electronic Engineering. At some booths, professors were seated while at some others, teachers’ assistants (TA) were waiting for the undergraduate students to come. Jeong Young-woon (Department of Electronic Engineering, 2nd year graduate) and Lee Jun-ho (Department of Electronic Engineering, 2nd year graduate) are both teachers’ assistants who were at the department of electronic engineering booth. According to Jeong, most students who already have strong interests in a certain major contacts the lab directly. The fair is thus helpful and informative for those who have interests in general and would like to know about the possibilities upon graduation. However, they both felt that the fair was not promoted enough. “Two to three years ago, I heard that the school advertised about the fair on newspapers as well. Now, they don’t and I think there are less students here,” said Jeong. From left: Professor Kim Ji-woo (Department of Global Health and Development, PhD), Professor Han Dong-woon (Department of Global Health and Development, PhD), and Choi Da-in (Department of Global Health and Development, Doctoral Program), giving an introduction of the Department of Global Health and Development. There were a wide variety of majors at the fair. One example is the Department of Global Health and Development. Professor Han Dong-woon along with Kim Ji-woo (Department of Global Health and Development, PhD) and Choi Da-in who is on his way to receiving his PhD, were proud to present their major as the first of its kind in Asia. Since it opened in 2012, it is already interacting with 27 other countries. It deals with not only global health theories, but also does field work overseas. Many graduate students even work as government officials in developing countries in the health and development sector. “The whole world is interlinked. You should not just put your focus on Korea only but also on what is going on abroad. Only then will you truly be able to understand why things are happening in this world,” said Han Dong-woon. The registration period for HYU graduate school is from October 11th to October 18th. Those who are interested but missed their chance to participate in the fair should not hesitate to contact the professors or the TAs, and pay a visit to their labs.

On September 16th, 2018, the sound of a grand orchestra filled the Paiknam Concert Hall at Hanyang University. The orchestras from the University of Stuttgart and Hanyang University collaborated to hold a joint concert. The concert was held in order to expand and share the art and culture between the two universities. The University of Stuttgart Orchestra and the Hanyang Orchestra performed, "I’d Like to Live on a Green Mountain (청산에 살리라)" together. The University of Stuttgart, widely known for its studies and research in the field of engineering, was established in 1829. Hanyang University and the University of Stuttgart had established and maintained a liaison since 1992. For the past two years, the presidents of both schools have been paying courtesy visits. In 2016, the president of Stuttgart University visited Hanyang University and suggested the idea of a joint concert. Discussions followed for years and the idea actualized, making it possible to hold this event. The joint concert consisted of 5 parts, which had the Hanyang and Stuttgart Orchestras playing back and forth at first, then they made a grand finale by coming together to play at the end. The Hanyang Orchestra performed Wagner’s Meistersinger Overture, and the Stuttgart orchestra performed Violin Concerto No. 1 Prokofiev and Mendelssohn, Symphony No. 4. The final performance started with Bizet; Carmen Overture and finished with “I’d Like to Live on a Green Mountain (청산에 살리라)," which is a piece written by the founder of Hanyang University, Kim Yeon-jun. The University of Stuttgart does not have a college of music. The orchestra is part of a club that consists of around 70 students and graduates. As for the Hanyang Orchestra, around 70 students composed of juniors and seniors played in the joint concert. The President of Hanyang University (in the middle), conductors, the concert master, and associates who made the joint concert possible pose for a picture on the 16th. "It was very touching to see Germany, which used to seem geographically and culturally so far from us, becoming one through the language of music. Especially the part where they all played 'I'd Like to Live on a Green Mountain,' which German students must have never heard of, nevertheless played so beautifully in harmony with the Hanyang Orchestra. I hope through holding many meaningful events with foreign universities, there would be more opportunities to have deeper relationships with them and share our different yet special cultures together,” commented Lee Angie, the senior manager of the Office of International Affairs at Hanyang University, who helped host the event. Through this year’s joint concert, the bond between the two schools will be much tighter, raising hope for more cooperation for more events. Next year, there will be a seminar or an academic session regarding the natural sciences and engineering. Unlike this year, when the host was Hanyang University itself, next year there is a possibility that Stuttgart will invite Hanyang University to Germany. Kim Hyung-Eun (Department of String & Wind Instruments, 4th year) (right), successfully contributed to the joint concert as the concert master. “It was an honor to play in the joint orchestra as the concert master. It was also a great experience for me to play with foreigner friends who were candid with their music and free in the way they express music. I was glad we, as an orchestra performing in the regular concert coming up, had the opportunity to be in tune with each other beforehand. The university orchestra festival is on November 7th at the Seoul Arts Center concert hall at 8 p.m. I hope many people will freely come and enjoy the music of the Hanyang Orchestra,” said Kim Hyung-Eun (Department of String & Wind Instruments, 4th year).

Started in 2009, Hanyang University School of Law (HUSL) is one of the first out of the 25 initial law-schools established in South Korea. Succeeding the former Hanyang College of Law, the current law-school has a top-tier faculty, educational facilities, dormitories, and extensive scholarships. The former College of Law was renowned for its high ratio of successful applicants and has produced 1200 successful candidates. Entailing its name, the current HUSL has also shown significant results during the past 10 years, having a success rate of around 80 percent on its applicants passing on their first submission. Of the current 42 highly competent professors, Professor Yang Chang-soo, the former justice of the Supreme Court, Yeo Mi-suk, the former chief judge of the Seoul High-Court, and Son Yong-geun, the former director of the Jurisdiction Training Institute have all newly joined HUSL. Having primarily three buildings, each serves its own purpose being equipped with individual study-rooms, international conference rooms, moot courts, and seminar rooms. HUSL provides 30 percent of the total tuition in the form of scholarship, with full scholarships offered to impoverished students. Merit-based, partial scholarships are provided to outstanding students with high grades and engagement such as taking part in the student council. “Although many mistake the law-school as having barriers due to its high tuition, it actually provides numerous opportunities such as scholarships and facilities such as dormitories,” maintained Lee Hyeong-kyu, the dean and a professor of HUSL. Professor Lee Hyeong-kyu (Dean & Professor of Law, President of the Korean Association of Law Schools) explains about Hanyang University School of Law during the interview held on the 28th of September. According to Lee, the current Law-school system was implemented in order to confront the many problems that the former Bar-Exams had. Due to the fact that the former test had no limitations in its application, many people applied for the test. However, with only around three percent being able to pass, many talented people ended up becoming socially ostracized after failing the exam. Additionally, one could apply for the Bar-Exam even if their major was unrelated, and education at universities became limp. Lee explained that while the former Bar-Exam was a selection of judicial officers, the current law system allows the training of such officials through education. Applying for Hanyang University School of Law The application period for HUSL begins from the first of October until the fifth for anyone who has graduated from a four-year university or has had equivalent scholastic achievement. Mainly five areas are covered throughout the entrance exam, which are the following: The Legal Education Eligibility Test (LEET) exam, school grades, a self-introduction letter, an officially approved English grade, and individual interviews. With elaborating that judicial officers are people who must execute the law from an objective view point, Lee gave advice to potential applicants of HUSL on how they should prepare for the enterance exam. According to Lee, the grades of one’s LEET exam takes a large portion of the entrance exam. As it is a test that is hard to raise grades in a short time. Lee also recommended that one spend much time with books. As the LEET exam measures one’s understanding of language, reading comprehension, especially in the field of reasoning, logic and inference, greatly helps in the preparation of the test. Still, as the exam requires one to solve many questions in a short time, Lee also gave an emphasis on how one should prepare by solving sample questions from previous LEET exams. School grades are an indication of the applicants' sincerity and perseverance throughout their school years, through which they can also show their comprehensive acquisition of knowledge. In addition, although not the most decisive factor, high scores of officially approved English exams are important, as falling behind the average will serve against an applicant. Furthermore, in the self-introduction letter, one should refrain from giving any information related to one's social status and simply include one's goal of becoming a judicial officer. Lastly, during the blind individual interview, applicants will be given a text which they have to read and understand in ten minutes and solve the given question. Note that some personality-related questions might appear. Lee is explaining the overall procedure of the admission's exam of Hanyang University School of Law and also provides advice to potential applicants. After the application period, the first successful candidates are announced during the early part of November. With the interview planned to be held in mid-November, the final successful candidates are usually announced in early-December. According to Lee, the current Law-school system has given everyone a chance. He hopes that many talented people apply and that many competent judicial officers are educated at HUSL.

Chuseok, literally known as “autumn eve,” is a three-day holiday to celebrate good harvest in Korea. The holiday could be prolonged with an additional day or two of substituted holiday, if the holiday itself overlaps with the weekend. People visit their ancestral hometowns and share a feast of Korean traditional food and some even practice charye, which is the ancestor memorial service at home, and seongmyo, which is the family visit to the ancestral graves. That is why during Chuseok, you may feel like Seoul is rather empty as if a zombie apocalypse has just happened. For the first few days, you may enjoy the empty seats on subways, but loneliness starts to creep in as time goes by, especially for foreign students. The Chuseok event in front of the Engineering Building I, September 20th, 2018. On September 20th from 11am to 3pm, a Chuseok event was held for both Korean and foreign students in front of Engineering Building I. The event was organized by the management team of the college of engineering and HISA, which is a group consisting of both Korean and foreign students to fully support foreign engineering students. Lee Moon-suk (Department of Organic and Nano Engineering, 3rd year) who is one of the HYCE International Student Ambassador (HISA) members, said “we hold Chuseok event every year. We thought it was a good idea because especially during this time, foreign students have nowhere to go, most of the restaurants are closed, and all their Korean friends have left the city. They end up just eating cup noodles and stay bored. We wanted to make Chuseok something that both Korean and international students can enjoy, so we came up with this event.” Decorating a traditional style fan at the Chuseok event. The Chuseok event consisted of four booths in total. The first booth was the food corner, where people could eat traditional Korean food such as jeon (Korean pancake), mandu (Korean dumplings), makgeolli (Korean rice wine), shikhae (Korean rice beverage for dessert), and sujeonggwa (Korean traditional cinnamon punch). The second booth was the craft area, where students draw and paint on fans, hahoetal (traditional Korean masks worn in t’al nori ceremony, to represent the stock characters needed in the dance) and gaksital (traditional Korean bridal mask). The third booth was a DIY corner where you could make your own songpyeon (half-moon-shaped rice cake)-shaped soaps. The fourth and the last booth was the one where you could play traditional Korean games such as tuho (requires players to throw sticks from a set distance into a large canister), palssireum (arm wrestling), jegichagi (players kick a paper jegi into the air, trying to keep it aloft), and ddakji chigi (game of folded paper tiles). Students could try on hanbok (traditional Korean dress) or take pictures with HISA students already in their hanbok attire. From left, Aimi (Mechanical Engineering, 4th year), Aliaa (Mechanical Engineering, 4th year), Fariza (Mechanical Engineering, 3rd year), and Aisyah (Mechanical Engineering, 4th year) Aimi (Mechanical Engineering, 4th year), Aliaa (Mechanical Engineering, 4th year), Fariza (Mechanical Engineering, 3rd year), and Aisyah (Mechanical Engineering, 4th year) each held a fan and masks they decorated. With big smiles on their faces, they said they thoroughly enjoyed the event. “We were informed about this event through email. Although it's raining today, we still very much enjoyed the booths and thought it was quite helpful for students like us to get familiarized with Chuseok. We learn about it in class, but here we get to try it out ourselves,” said Aisyah. “For me, I also tried the game booth, and although I did enjoy it, I wish they would at least give me a brief explanation about the history of the game as they simply told me what to do,” said Aimi. In terms of improvement, everybody agreed that the booth should be moved to a more spacious area, as it was right in front of the building causing chaos among students in line for the booths, and students rushing to class. Nevertheless, the bustling booth was a heartwarming scene in a gloomy weather. Happy Chuseok! Park Joo-hyun firstname.lastname@example.org Photos by Kang Cho-hyun
With the kick-off of Blackboard as the new Learning Management System (LMS) for ERICA Campus starting from second semester of 2018, students have begun adapting to the new system. Along with this change, some may be wondering why Hanyang University ERICA Campus implemented Blackboard and what the features of the program are compared to the previous LMS. ERICA Campus’ Center for Teaching and Learning’s Research Professor Cho Yong-hyun and staff of the Office of Academic Affairs at the center Kim Seon-yong further elaborated on the significance of Blackboard and its noticeable features. Cho Yong-hyun (ERICA Campus’ Center for Teaching and Learning’s Research Professor, far left) and Kim Seon-yong (staff of the Office of Academic Affairs at the center, far right) are part of the Center for Learning and Teaching in ERICA Campus. (Photo Courtesy of Kim) The reason behind ERICA Campus’ implementation of Blackboard Learn Ultra, which is the newer version, as the new Learning Management System is that as part of the PRogram for Industrial needs - Matched Education (PRIME) project which ends in 2018, ERICA Campus decided to apply this system. There has been six months of system development starting on March 2018 and various Blackboard educational workshops for the professors. Kim provided assistance by creating manuals and guidebooks for Blackboard LMS. In addition, Cho stated that compared to the previous learning management system, Blackboard is advanced in that it is a global “edu-tech” (education and technology) platform with brilliant expandability. English home menu (on the left) for ERICA Campus' Blackboard. (Photo Courtesy of Kim) There are some features of Blackboard worth taking note of. On the system, there is a plagiarism-detecting program unlike in the former portal system. In addition, the Center for Teaching and Learning has included the SMS feature, which enables direct text message notices to students, and professors can notify the students with any urgent course updates. Cho added that students should be aware of the limitations to the number of times they can upload an assignment to the system. Furthermore, under the ‘Course room’ section, there is the “Collaborate” category. This enables professors to film video lectures and promotes active communications and discussions with students. Although this feature has not been widely applied to the courses yet, there are plans to implement it, especially in program-based learning (PBL) classes. Cho stated that as Blackboard is still in its early stages for ERICA campus, there is plenty of room for adjustment and improvement. The Center for Teaching and Learning is constantly working to keep the program up to date and inform students and professors of any change. The center is always open for those who have inquiries. Cho and Kim hopes that the educational features of Blackboard will promote self-learning education for students and encourage active communications between the students and professors.

The first time Google attempted at predicting the outbreaks of flu using big data, the result was a failure. In their second attempt, however, by collaborating with social scientists, they produced a successful result. This particular incident shows the importance of fusion research. Professor Cha Jae-hyuk (Department of Computer Science and Engineering) and his team also stand on this point through their research in big data-based real-time social environment monitoring and simulation system development. The aim of the research was to combine the traditional social science and big data process technology to allow new insights of social problems. Cha Jae-hyuk (Department of Computer Science and Engineering), September 22, at Office of Information and Communications Technology Services. Today’s society forms one big network in which big data plays a crucial role in organizing complex social problems. Among these, Cha focused on three social problems. First, he studied the relationship between the welfare for the disabled and the mobility of the disabled. Big data processing made it possible to keep track of the mobility pattern of the disabled and the entailing satisfaction towards life. Cha found that it is how many places they visit, not how far they travel, that determines their satisfaction. This discovery will help suggest new and better paradigm in welfare for the disabled when it comes to their transportation. Second, he studied the response of the government and the society to the infectious diseases. Through five mediums of news, he found that for Middle East Respiratory Syndrome (MERS), the official response of the government and that of the society were vastly different. With more data, Cha intends to use it as an evaluation tool for later responses. Last, Cha collected the data via social networking sites about how the anxiety in the society changes depending on time and region. He tried to look into its relationship with the social problems and found slight changes in the public sentiment. With further data, Cha plans to relate it with social problems such as suicide rate. Cha advised to be interested in the convergence with other disciplines and in new keywords. Cha anticipates that the combination of social science and big data technology could help draw more accurate interpretation of the social phenomena. In this regard, the research means more than the result itself. More importantly, it shows a hopeful prospect of the fusion research. Cha believes the three studies have shown that synergy effect of the fusion research can bring better results and solve bigger problems. As he suggests, fusion research “can be the new strength” in our society. For that reason, Cha has set two goals. One is to establish a data processing system integration platform. The platform will be open to anyone to freely access the research results and reenact using the program. Another goal is to suggest a fusion research methodology of how the usage of fusion research may bring out a better result. This is why Cha also encourages the students of Hanyang to engage themselves in the fusion research as well. “Take an active interest in converging with other disciplines.” Cha advises, “be interested in, participate in, and listen to the other newly appearing keywords in our society.” Lim Ji-woo firstname.lastname@example.org Photos by Lee Jin-myung
