[Faculty]The Expedition to Living Knowledge

Mark Twain said that every person is a book, each year a chapter. People seek the meaning of life through their experiences. Here is Professor You Yeong-mahn (Department of Educational Technology), a knowledge ecologist who integrates people's experiences into new knowledge. Professor You Yeong-mahn (Department of Educational Technology) is a knowledge ecologist who integrates people's experiences into new knowledge. Communicating with the public You is well-known for his active communication with the public. You featured intermittently in television programs such as tvN’s No Way I’m an Adult and CBS’s Sebasi Talk. You delivers simple but permeating messages – such as tree (namu) does not blame (namurada) anyone. “There is a big difference between the role of a university lecturer and a public speaker,” said You. “The message should be concise and thought-provoking towards the public.” Knowledge ecology labels the general public as an agent of knowledge management. You's exposure to mass media is deeply related to knowledge ecology. You has published 88 books that meet the public interest. Besides, You posts a series of articles through social media where he interacts with his subscribers. You recently published Do Not Meet Someone Like This, which builds on his posts on Brunch, an SNS platform. It is a book that covers human relations. “What determines who I am is who I meet,” said You. “People should reflect on themselves before judging others.” You advises people to look back on themselves through Do Not Meet Someone Like This. (Photo courtesy of Namusaenggak) Curved rather than being straightforward You recalled his astonishment upon reading the comments on an article introducing Do Not Meet Someone Like This. “Some expressed mere anger and hostility without even reading the book,” said You. “What I found was a heartless atmosphere in society.” You referred to modern society as ‘straightforward,’ where you are faced with fierce competition. “People are demanded to aim further, work harder, and achieve faster,” explained You. “All that remains is emptiness.” You criticized current social conditions by citing Antoni Gaudi’s words, "The straight line belongs to men, the curved one to God." The knowledge ecologist proposed ‘curved’ values such as – diversity, harmony, and flexibility – as an alternative social discourse. “Curved values are enlightened through experience,” said You. The professor defined them as wisdom accumulated from continuous trial and error. They provide solutions to hardship with insights that hit the bull's-eye. Yoo suggested 'curved' values of – diversity, harmony, and flexibility – as an alternative to 'straightforward' social discourse. Experience as the source of creativity You recounted how his experiences led to creativity. “I helped my parents as a farmer, worked as a welder, and read books as a student,” said the knowledge ecologist. You said his experiences converged into a database. Along with extensive reading, it became a source of his unique content. You encouraged students of Hanyang to compile their database. “You need language to visualize what you think,” advised You. “There is no sense if you are in the absence of vocabulary.” The professor suggested that students read and behave. “Reading is rather physical labor than mental labor,” said You. “In order to master what you read, experience and reading should be done at the same time.” You highlighted the importance of experience as well as reading books. Some people say that a concept without experience is vain, and a thoughtless experience is dangerous. You is exploring the ecosystem of knowledge through his experience and interaction with the public. Oh Kyu-jin alex684@hanyang.ac.kr Photos by Kim Ju-eun

[Faculty]Hanyang University Professors Talk About Settling in Korea

Following Korea’s rapid development and increasing influence in international relations, the inflow of foreigners into Korea has increased greatly compared to the last two decades. Last year, there were over 2.3 million foreigners living in the country, and Hanyang University currently has around 3,000 international students studying in both campuses. Thanks to Korea’s leading industries, culture, safe environment and universities, more foreigners are taking an interest in prolonging their stay in the country. Two of the Hanyang University professors who have decided to make their stay in Korea long-term are Professor Krisda Chaemsaithong (Department of English Language and Literature) and Professor Michael William Brandon (Center for Creative Convergence Education). As of November 20th, Chaemsaithong has become a naturalized Korean citizen, while Brandon has acquired a marriage visa after marrying his Korean wife five years ago. Although the two Hanyang faculty members differentiate in status, they have both obtained the right to stay in Korea permanently. Professor Krisda Chaemsaithong (Department of English Language and Literature) has recently become a naturalized Korean citizen on November 20th. Chaemsaithong said practicality was one of his reasons for obtaining Korean citizenship. He has been living in Korea for seven years and has always fulfilled his duties. Apart from protecting one’s country, Chaemsaithong believed he was doing everything an ordinary Korean would do for their country, so he thought it was about time that he took the next step. In addition, as a professor of a university in Korea, obtaining citizenship would mean that he could represent his soon-to-be country. Thanks to the Korean government acknowledging his ‘outstanding talent,’ in addition to his highly educated background and numerous publications, Chaemsaithong was able to naturalize. Korea invites accomplished scholars from other countries to naturalize by offering a faster naturalization process than other methods. While the waiting list for regular naturalizations and naturalizations through marriage is longer and limits applicants to those who have lived in Korea from two to five years, foreigners with ‘outstanding talent’ can obtain Korean citizenship in just four months, which was how long Chaemsaithong had to wait to get his. Chaemsaithong went through three major steps during his naturalization process: applying for naturalization and submitting the required documents, the Ministry of Justice evaluating his case, and an interview session where he was tested on his knowledge of Korea. He also submitted a letter of recommendation written by Hanyang President Kim Woo-seung. The thesis papers he submitted had to be published no longer than five years in internationally recognized journals, which in his case, amounted to 25 thesis papers. Chaemsaithong poses with the textbook provided by the Ministry of Justice titled '나는 자랑스러운 한국인,' which translates to Korean into 'I am a proud Korean.' The last test was the actual interview, which included around 15 to 20 questions about Korean language, culture, history, law, and duties as a citizen, said Chaemsaithong. He added that the Ministry of Justice provided him with a textbook about the things he would be tested on, which he said was around the level of secondary school for Koreans and had many visual aids like cartoons and photos. The passing score is 60 percent. One question that he had difficulty answering was naming four Korean traditional holidays. “So, I said there is Seol (Korean New Year), and there is Chuseok (Korean Thanksgiving), but I don’t know the other two,” said Chaemsaithong. “There is Dano (spring festival) and other things that didn’t get mentioned in this book, so I didn’t know that.” The final traditional holiday is Hansik, the 105th day after the winter solstice, which means cold food in Korean. Chaemsaithong was sworn in as a Korean citizen at an oath ceremony held in Gwacheon, Gyeonggi-do, on November 20th. (Photo courtesy of Chaemsaithong) Results came fast as Chaemsaithong said he received a call from a government employee the next day saying that he had passed. In mid-November, Chaemsaithong participated in his oath ceremony in Gwacheon, Gyeonggi-do. He swore an oath to do his duties as a Korean citizen with 14 other naturalizing foreigners. Professor Michael William Brandon (Center for Creative Convergence Education) talked about marriage, immigration, and life in Korea. On the other hand, Professor Michael William Brandon (Center for Creative Convergence Education) has gained the right to stay in Korea through marriage. Brandon is from the United Kingdom and has been living in Korea for over 10 years. He came to Korea with a working visa and later met his wife and has since acquired a marriage visa. As a foreigner, in order to make his marriage legal in both his native country and Korea, Brandon and his wife needed to get approval from both countries, a task that was challenging, as it needed to be done separately. The process requires a lot of paperwork, which needs to be prepared by both spouses in both native languages and issued by official offices of their home countries. In Brandon’s case, he had to visit the British Embassy, while his wife submitted her paperwork at a city hall. This procedure may cost a lot of money, as papers (a total of 11 required documents) needed to be translated to Korean by qualified transcribers acknowledged by the Korean government. After all the paperwork was submitted to both countries’ offices, the Korean counterpart sorted out the documents and legitimized the couple's marriage. “They are extremely clear about the documents you need to go through the procedure,” said Brandon. “It's an arduous task because the documentation process requires a lot of work. However, it was also easy because of the clarity involved in the process, so for that, I am quite grateful for both sides.” Brandon also added that, as immigration laws are fluid, people can accidently prepare outdated forms, which would have to be submitted again. “There are elements that I have been involved with living here in Korea where people have been more accommodating than I would have expected,” said Brandon. “That has made my ability to participate and engage with certain Korean aspects possible, and as a result, it has given me a little bit of feeling that I can also be living here, being part of the generation of elements of Korean culture as well.” Brandon currently lives with his wife and two children.

[Faculty]Illuminating Dasan, an Innovative Thinker of the Joseon Dynasty

Dasan Jeong Yak-yong is considered one of the greatest thinkers in the late Joseon dynasty. Dasan -- a scholar and politician throughout the late 18th and early 19th century -- is well known for his pragmatic approach towards Confucianism, publishing highly influential works on philosophy, science, and theories of government. Illustrating Dasan's work is Professor Jung Min (Department of Korean Language and Literature), a scholar who has devoted his career to illuminate the values of Dasan and his publications. Professor Jung Min (Department of Korean Language and Literature) explores through the values of Dasan Jeong Yak-yong, one of the greatest thinkers of the Joseon dynasty. Jung recently completed publishing his series of Dasan Dokbon in Hankook Ilbo, which is a critical biography that takes a glimpse into Dasan's unknown life. “The articles cast light upon Dasan’s early years as a politician,” said Jung. “It was an age of turbulence following the breakdown of dominating Neo-Confucian values.” Jung portrayed Dasan as an ambitious intellectual who actively sought a breakthrough in social issues. Fortunately, Dasan received political support from King Jeong-jo, the reformist monarch who ruled Joseon in the late 18th century. Jung recently completed the Dasan Dokbon series and published it in book form. (Photo courtesy of Hankook Ilbo) Jung paid attention to Dasan’s approach to Catholicism throughout Dasan Dokbon. Unlike some scholars who see Dasan as a devout Catholic in his youth, Jung interpreted that Dasan regarded Catholicism as a field of study rather than a religion. “Dasan was deeply interested in the promotion of public welfare through science,” said Jung. “This is why he embraced Catholicism as a major ideological foundation of Western science.” Ironically, Catholicism is what forced Dasan out of his position, as it was counted as heresy by the ones with vested rights. Dasan was involved in the Catholic Persecution of 1801, and it ended his political career. Dasan was exiled to Gangjin, where he concentrated on his publications for 19 years. Jung plans to cover Dasan’s years of banishment through his further works. Jung claims that Dasan’s management of information will give out new insights to people living in modern society. “There is no Korean scholar who can surpass Dasan in the quantitative and qualitative richness in publications,” said Jung. “Dasan offered a new mechanism of processing voluminous information which is co-operated with his pupils.” Jung stated that Dasan’s competence as a data compiler will provide templates to which are required in the era of big data and collective intelligence. Jung sheds light on Dasan's role as a data compiler in his 19-year-banishment at Gangjin. Jung highlighted the importance of changing perspective. “Stereotypes prevent the emergence of new thoughts and ideas,” said Jung. “I tried not to confine myself to the traditional view on Dasan.” Jung’s humanistic insights to find connections with the society produced innovative results in his Dasan studies. As some people say, you can expect no influence if you are not susceptible to influence. Oh Kyu-jin alex684@hanyang.ac.kr Photos by Kim Ju-eun

[Faculty]Incorporating Philosophy into Science and Life

Professor Yi Sang-wook (Department of Philosophy) gave a lecture on "The Unknown Story of Geniuses" on the Distinguishing Class (차이나는 클라스) show on JTBC which premiered on June 5th. Yi explained the prejudices in science and of scientifically important figures, and accentuated the importance of learning the philosophy of science in order to prevent such blind faith. Professor Yi Sang-wook (Department of Philosophy) is explaining the key ideas in his lecture on the JTBC show Distinguishing Class (차이나는 클라스). Distinguishing Class suggested that the lecture be based on Yi’s book Science Calls This Imagination, published earlier this year. As his final statements on the show, Yi encouraged students to study the philosophy of science. He added during the interview that it is important to make wise decisions based on media literacy, which is the ability to decode the various forms of media autonomously, especially in our modern society which is overflowing with information. He argued that the ability to understand, criticize, and oversee society, as a participating citizen, is crucial in the 21st century. He added that the mandatory elective course at Hanyang University named “Philosophical Understanding of Science Technology” was created for this purpose, to foster civic literacy. Piles of books were stacked in the office, clearly showing Yi's passion for them. Yi has experiences of giving lectures to students from science high schools, and he pointed out that many students view only the renowned scientists as making important discoveries, based on the elitism that they had grown accustomed to. He argued, “Science is fundamentally a social activity.” Not even a genius scientist can influence a large chunk of science, but many small contributions from unknown scientists lead up to the discovery of an innovative scientist that lead human civilization. Yi says he loves the family-like atmosphere of the Department of Philosophy, especially the rolling papers his students prepare for him every year. Yi originally majored in and had a master’s degree in Physics. His doctoral degree of Philosophy at the London School of Economics and Political Science was a slight change of direction, although he himself does not think so. He stated that until the 19th to early 20th century, physics handled science philosophy, as Heinrich Rudolf Hertz's books introduced contents such as how physics sees the world. Physics research processes were very labor-oriented and repetitive, whereas he found himself well-suited to philosophy, since he liked to explore the fundamental questions of life. Yi stated his wishes to write more books in the near future. He has also been acting as a member of the World Commission on the Ethics of Scientific Knowledge and Technology (COMEST) since last year, and he has been engaging in creating the declaration of ethics in regard to artificial intelligence. He has come to realize the necessity of international cooperation in changing the world, and the efforts required to actually have an impact on global society, through working at the United Nations.

[Faculty]Thoughts on Korean English Education

Although English is not an official language in Korea, it is still considered a mandatory part of education from primary to college. Especially because English exam scores have become a basic requirement for jobs or any other program applications today, gaining competency in the language is now a competition for Korean students from an early age. Lee Kwang-hee, a professor in the Department of English Language and Literature and a current member of the board of directors at Korea Munhwasa (한국문화사), a renowned publishing company in Korea, has shared his life story and thoughts on this phenomenon. Lee Kwang-hee (Department of English Language and Literature) is sharing his life story and thoughts during the interview in his office at Korea Munhwasa (한국문화사). Lee’s deep affection for English began in his college years at Hanyang. With his profound love for the school, Lee completed all his bachelor's, master's, and doctor's degrees at Hanyang University, all in the department of English Language and Literature. According to Lee, his choice of department was not due to his passion but because his highest score was in English, which made him think he had a talent in it. However, life as a student in this department completely changed his path. “You don’t learn how to speak better English in this department. Rather, you learn about the literature and human language, which is part of our life and instinct. In other words, you study about life and human nature, while using English instead of Korean,” said Lee. Despite his skills and competency, Lee had not always planned on becoming a professor from the start. According to Lee, his life as an English department student was always unclear, especially as the Korean economy was at its lowest point at that time due to IMF. Luckily, Lee found some recruitment advertisements for English academies and decided to apply to become an English teacher. However, he had to face constant rejections as he was quite young, and HYU was renowned more for its technology departments than language departments. “In the end, my desperation got me through. I was finally teaching in one of the academies, but because I wasn’t getting enough students or teaching bigger classes, I was barely surviving with the minimum wage,” said Lee. Lee also has over 15 books published that are loved and used by students throughout the country. Fortunately for Lee, he was able to quickly gain his popularity and recognition as an English teacher after substituting for one of the bigger classes. With this turn of events, he quickly became one of the high-earning, popular teachers that taught classes everyday. There were endless calls for him, and at one point, he thought he was living the best life. However, years had passed, and Lee was constantly feeling a void that could not be filled. One day during a class, he realized that he had become a simple technician and a parrot that teaches students on how to solve questions, rather than why they work that way. With a recommendation from his professor, Lee went on to obtain his master's degree at HYU. “I remember why I fell in love with learning English. Learning a language is like developing a whole new world in you. A language has its own system and mechanisms like science, and one should be able to utilize it with intuition. I realized that that is what English education in Korea has been lacking. When I'm teaching, I mostly see students that are simply trained to speak English. They don’t speak the language because they truly understand it. Students treat it like it’s some sort of simple technical equation because that’s what they’ve been trained to do their whole lives, and this applies to all languages being taught in Korea.” "I hope more talented intellectuals or even students with creative ideas for bettering the Brown Study would feel free to contact me. It's an open, digitalized platform for everyone." To the current situation, Lee added that the intellectuals are also at fault. “I think that this kind of problem exists because the studies and realizations that us intellectuals have remain in our own league. There needs to be better communication among the language intellectuals as educators and students." Lee commented that it would be the best if those with a language degree from universities become teachers at English academies and pass on what they have learned in universities to their students. With this in mind, Lee has created an online study platform called the Brown Study in hopes of creating an open, digitalized platform with all kinds of study materials in the language and humanities field that anyone can access. This way, even professors who have retired or any other intellectuals can leave their work online and teach the students who wish to truly learn more than just the simple technicalities. “I hope this can become a communication outlet for both students and intellectuals. I believe that as long as you’re always intellectually curious and keep an open mind, you will always succeed,” said Lee. Park Joo-hyun julia1114@hanyang.ac.kr Photos by Lee Jin-myung

[Faculty]The “Future Medical Scientist Award” Winner

Professor Lee Won-june (Department of Ophthalmology) received the “Future Medical Scientist Award” on August 22nd, 2018 at the Shilla Hotel where the 10th Future Medical Scientist Awards Ceremony was held. He has been working at the Hanyang University Medical Center treating patients with glaucoma and cataracts since the beginning of the year. Lee shared an insight about what it is like to work as a fellow and to work in a department that specializes in a simple fruit of a certain illness. Professor Lee Won-june (Departmnent of Ophthalmology) joined NewsH on September 7th, 2018 for an interview at Hanyang University Medical Center. The “Future Medical Scientist Award” is special in that it limits its potential award winners to “fellows.” The award was given to encourage the fellows to lead the future of Korean medical science. Fellows are evaluated by many crucial factors including impact factor (number of citations), journal impact, factors related to the fellows' backgrounds like the hospital they work for, and more. For those of you not familiar with the concept of a fellow, a fellowship is what you call a period of medical training that a medical specialist may choose to undertake after residency. As Lee puts it, it is a position that is “caught in the middle,” since it is neither a professor nor a resident. The treatment of a fellow is not well off either, he said. It is a position to work, train, and study. Lee felt rewarded after receiving the award with all the hardships he had dealt with as a fellow. Aside from how well the thesis paper is written, Lee explained that the whole process of writing the dissertation during your fellowship period helps you grow. As a fellow himself, he tried to write in a well-organized manner so that other professionals could easily understand and relate to the thesis. Since writing a thesis is a mandatory step that all must take in order to fulfill the career of a medical professional, there are some theses that seem to be written just for the purpose of writing a thesis. However, professor Lee emphasized the importance of taking into account the freshness of your ideas, its usefulness, practicality, and how helpful the thesis could be for patients when writing a dissertation. Professor Lee works in the Department of Ophthalmology, but to be more specific, he majors in glaucoma and cataracts. After undergoing residency in ophthalmology and trying out for fellowship, professor Lee had to decide what he wanted to major in as a fellow. Being an expert in glaucoma was a fascinating idea for him since glaucoma is a department that majors in one single illness. Also, there are no permanent solutions for glaucoma, so an expert in this field can keep a long-term relationship with patients. “The fact that there is not yet a definite cure motivates me to work and study glaucoma harder.” Professor Lee is showing NewsH his award-winning thesis and the tools he used for his research. Lee’s hard work seems to be paying off as he has received many awards from various award ceremonies. In April of 2018, professor Lee also received an award from the 119th Symposium held by the Korean Ophthalmological Society. The research findings from his dissertation that he received an award for was published in “Ophthalmology,” the most well-known academic journal in the field of ophthalmology. Lee is now the only ophthalmologist who specializes in glaucoma at Hanyang University Medical Center. He said that he feels he has a heavy responsibility to lead the way for his glaucoma patients that he will come to see and treat for a long time.

[Faculty]Old Poetry Gathered into a Book

People say that being a parent is a whole new experience that brings so many unexperienced emotions and thoughts into one's life. Professor Pak Dong-uk (Korean Language & Literature) felt the same as any other father. With his son being born at a relatively late age for him, he was mesmerized by the feelings the little one gave him. He did not stop there but put his overflowing feelings into poem and searched more vigorously through old Korean poems written about family and being a father. Pak recently published his third book on the subject, No Flower Better that You. The title of this collection of poems sounds as if it is a love story or a love letter and indeed, it is. It all started with a question: Did fathers from the Joseon dynasty really disregard their daughters as portrayed in the dramas? It is widely known that Joseon – a country that later became the Republic of Korea – believed strongly in Confucianism. One commonly held belief was that women deserved fewer rights and respect than they do in contemporary Korean society. Wives who were forced back to work the day after giving birth to a daughter instead of a precious son are commonly portrayed in films and dramas that take place on the pages of our history. But as a father, Pak wondered if that would be true. News H interviewed Pak Dong-uk (Korean Language & Literature) in the Engineering BuildingⅡ. Pak's No Flower Better than You was published on May 18th. Using his early morning time before going to his 9 a.m. classes, Pak was able to find dozens of old poems written by fathers to their daughters, filled with nothing but love. “I figured fathers loved their daughters throughout history,” smiled Pak. His work does not necessarily say that all daughters during the Joseon Dynasty were loved as much as the daughters of the contemporary world, but it does point out that ladies in affluent families (enough for their father to be literate) were loved by their fathers, unlike the common misconception. It has been seven years since my daughter has been born, I can’t let her go out the doors now. A crow reminds you playing with ink, And a bracken reminds of your small hands picking up chestnuts. You wouldn’t have gotten used to getting ready in the morning with your mother. Who would comfort you when you cry for dad at night? Just wait child, for I will hug you the first thing I get back home, Even before I get my coats off. <Thinking of my daughter>, Jo Wee-han Pak himself defines a father as "a person who does not fall." He remarked that he feels so much more responsibility to his family and that having a child has widened his perspective of the world. “I now treat my students differently, because I keep thinking how precious they must be to their own parents.” Two more books on the topic of married couples will be published later this year. Pak still has endless topics he would love to write, collect and introduce old poems about. He gave readers of News H a special sneak peek into his upcoming book that will be published later this year. He said “It's about a truely genius poet named Lee Un-jin, who died at the age of 27. He wrote a series of poems with 170 poems in it, and that's all I can reveal now,” smiled Pak. The professor was humorous for the entire interview, yet he had much seriousness in his face.

[Faculty]Population Problems of the Aging Korean Society

Hanyang University's Institute of Aging Society, according to Professor Lee Sam-sik (Department of Policy Science), has a lot of advantages as an academic institute with such an interest. Having Lee as the director, the institute was established in 2008 and has been dedicated to conducting research regarding today's aging society problems in Korea. This week, Lee spoke about the role of the institute and the ongoing population problem regarding the aging society in South Korea. Professor Lee Sam-sik (Department of Policy Science), the director of the Institute of Aging Society at Hanyang University, explained the research in progress at the institute on July 13th, 2018. The main goal of the Institute of Aging Society is to fuse the field of engineering with that of humanities and social science to achieve social innovation. This institution strives to realize “active aging,” which is intended to “inform discussion and the formulation of action plans that promote healthy and active aging,” according to the World Health Organization (WHO). There are six subsidiary research organizations of the Institute of Aging Society and Lee is the representative of the population strategy research group. This organization often forms a study group of external associations to develop and suggest the nation’s policies, vision, and strategy. The smart health aging research group involves the engineering field, where it is put to use in order to solve problems that the elderly face. The fruits of this group will increase the quality of people’s lives domestically, and motivate the growth of the international market. The advanced wellndess research group focuses on studies of exercise, food, and nutrition. Humans' taste organs degrade the most as they age. This group researches ways that the brain can register unsavory food as something delicious, or to protect the elderly from the damage of a fall, by developing textiles that act as an airbag. “Just like Spiderman’s clothing,” he smiled while he explained the logic of the idea. The lifecare research group conducts studies on ways to handle emergency situations. Age-friendly cities and communities research group targets making the whole city senior-friendly. Last but not least, the “third age” (referring to the 30 years after the age 40) research group conducts further research on leisure and the cultural life of the seniors. From 2006, the Korean government started to implement policies to supplement the nation’s low birth rate and the rapidly aging society in Korea. Lee emphasized the importance to strengthen not only the field of engineering but field of humanities and social sciences at Hanyang University. “The fusion of those two studies will not only bring important contributions to society but will also bring practical and creative solutions to population problems that our generation faces today,” said Lee. The gist of the population problem is that the growth rate of senior citizens is increasing at an unprecedented speed while there are increasingly fewer of the younger generations to support them. The average age of senior citizens is increasing, with most of them being 80 or older. In addition, households with a senior citizen living alone is increasing as well. The engineering departments have come up with the idea of creating big data by using a sensor to detect all circumstantial behaviors of the elderly. This way, it would be easier to spot any abnormal behavior and prevent accidents from happening. Professor Lee Sam-sik emphasized the importance of fusion research of diverse fields in pursuit of solving the problems that Korean society faces due to its rapidly aging population. “The way to handle the fast approach of an aging society is to resolve population problems. This is not something that can be solved at once, so we must look into and ameliorate things that we can handle for now. As we live in a time where human beings can live up past age 100, the balance between money, health, and civilized living for the elderly has become more important than ever. The government and institutions like the Institute of Aging Society at Hanyang University should make greater efforts to lessen the burden that the younger generation holds to support their elders, while seeking optimal welfare for the senior citizens.” Kim Hyun-soo soosoupkimmy@hanyang.ac.kr Photos by Park Geun-hyung

[Faculty]Increasing the Efficiency of Solar Batteries

Global warming is a clear threat to the human race. After long disputes over the validity of the phenomenon for nearly a quarter of a century, it has been revealed after an investigation of the fossil fuel industry that global warming is a real threat. The past scientific disputes had in fact been a result of interventions by the industry to protect their business. So what now? Aside from bringing justice to these corporations, one of the biggest assignments facing humanity is the creation of sustainable energy. For this task, the recent finding by Professor Park Jea-gun (Department of Electronic Engineering) has shed a new light of hope. Park Jea-gun (Department of Electronic Engineering) explains global warming. Simply put, Professor Park found a new way to improve the power conversion efficiency of our standard solar batteries. However, the process had been far from simple, and many complications had confronted Park on his journey. Solar power is among the few established sources of sustainable energy, which include tidal, wind, and hydraulic power. However, despite the research and development of solar batteries over the past 20 years, the highest power conversion efficiency, meaning the rate of the electrical energy that is converted from its original form, remained a staggering two percent. Park’s research had raised this rate to 4.11 percent. To give a brief explanation on the mechanics of solar energy, sunlight includes three types of rays: ultraviolet rays, infrared rays, and visible rays. These rays are projected in a form of waves, which are essentially energy. Currently, our solar batteries convert only visible rays, which is where Park began questioning a possible improvement. What Park did was to install quantum dots, a core semiconductor that is capped by an outer cell, on the silicone surface of the standard solar battery. A size smaller than 10 nanometers, quantum dots convert UV rays into visible rays, a process referred to as ‘energy-down-shift’. With this conversion, solar batteries could begin to convert a proportion of UV rays. An illustration of how a quantum dot converts UV rays for solar batteries (Photo courtesy of Park) This initial finding, published in 2014, improved the power conversion efficiency of solar batteries to three percent. Park was yet to be satisfied. Building on the scientific fact that the yield of energy from visible rays are greatest in the colors red and green, Park quickly moved to improve the new model. The problem was that the standard quantum dots converted UV rays to blue visible rays. Park resorted another process of quantum mechanics called ‘energy tuning’, which allowed the standard quantum dot to finally convert UV rays in a yellowish light, well between the rays of red and green. His new finding improved the power conversion efficiency to four percent. Now comes the final stage of Parks recent journey. Although his improvements to the standard solar battery was immensely significant, one flaw of his model was that it was composed of cadmium, a heavily regulated material. To make his model feasible for commercialized use, Park had to find a replacement for cadmium, which he found in a material called gallium. With his new improvement, Park’s research had been recognized and published in one of the most internationally renowned scientific journal, Advanced Energy Materials. Park’s research had been recognized and published in Advanced Energy Materials. As a word of advice to students aspiring to follow a scientific career, Park emphasized the importance of attitude. According to Park, the rate of development of scientific technology has grown exponentially within the past few decades. Students need to be aware of this, and needs to make an effort to follow recent discoveries and trending methods as opposed to focusing on traditional learning through textbooks. He also advised students to be well studied in software technologies, as they have grown much more significant in all domains of engineering. “The key is fundamental base, and a prepared attitude,” commented Park.

[Faculty]Childhood Inspiration Shared With Pupils

Some people have ‘that moment’ when they decide what career path to pursue. For Kim Eung-soo (Department of String and Wind Instruments), it was when he first listened to Mozart’s Violin Concertos when he was in elementary school. After about 30 years, Kim organized a concert with his students to play his childhood inspiration at Paiknam Art hall, on April 30th. Not a lot of concert play the entire concertos (comprised of five songs) in one occassion, as the pieces are long and very difficult to play. It is most likely that Kim’s performance was the first one in Korean musical history to play the whole set of songs at once. To perfect the songs, Kim and ensemble SOL practiced for two months for the concert. Kim Hyung-eun (String & Wind Instruments,4th year) mentioned “after this concert, preparing other songs and concerts felt whole lot easier.” Unlike other concerts, where there are separate team to organize the event, the performers had to do everything from advertising, contacting journalists and putting up posters on the wall. Kim Eung-soo (Department of String and Wind Instruments) is explaining about the meaning of ensemble SOL at Paiknam Art hall, on April 30th. The ensemble members all students of Kim, with 15 violin players. It is not common for a professor and students to play in a same concert, as there are unignorable gaps between the performers. What Kim wanted to make through the event is to make a “fence” for his students to keep in touch and to cooperate with eath other even after the graduation. Kim, the student, also agreed on the point commenting “through overcoming the hardships together, the performers became really close.” She also thanked her professor for making the concert possible. Kim graduated all three universities; University of Music and Performing arts Vienna, University of Music and Performing arts Gratz and Hannover Universty of Music, Drama and Media summa kum laude (first of class, meaning ‘with highest honor’ in English). However, despite of his awards and career, I could tell he is a very humble person through his remarks such as “I personally don’t think I am good enough to teach anyone,” “I am honored to participate in one of the most great things humanly possible, education.” Kim also emphasized that Hanyang University students have the necessary skills to become top musicians, so that they need to have more pride in our school and be more self-content. Kim and some of his students, namely Kim Hyung-eun, is participating in Korean Chamber Music Concert on coming 27th and 29th of June, at Seoul Arts Center. He also plans to make more events where he can harmonize with his students sometime next month. With the love and passion for both violin and his students, his plans seem bright. "Have more confidence" was the encouragement message Kim wants to give to his students. Kim so-yun dash070@naver.com Photos by Kang Cho-hyun
