[Student]Step by Step, Changing the World

‘Changing the world’ might seem as a rather abstract goal to achieve as a university student. On the third floor of the Business School, there are 25 student interns whom are here for a semester in the Hanyang Business Lab to actually achieve this dream. Lee You-jin (Business Administration, 3rd year) and Yun Jeong-ah (Chinese Language and Literature, 4th year) were in the midst of reaching their goals through two missions: ‘Artist Tak’ and ‘Mindful Laundry’. Supporting students with ambition Hanyang Business Lab is one of the characterized programs of the Business school for students to better prepare themselves for the Fourth Industrial Revolution and to better experience the practical affairs of business. There are seven different labs in this program, starting from Artificial Intelligence to Quantitative Analytics. As the second semester’s members, Lee and Yun are working within the Social Innovation Lab with two other members led by professor Shin Hyun-sang. They work to make a platform that could positively influence the society and are therefore specifying their wishes through the two projects. From an individual artist to a platform Lee spends the whole day in the lab, creating better ideas for 'Artist Tak'. Lee is the manager of a facebook page ‘Artist Tak’, (Click HERE) which is a branded platform of Tak Yong-joon who became an artist after a general paralysis. “Tak suffered from a general paralysis after his honeymoon when he was 29. Most suffer depression after they are paralyzed. Unlike most people, he instead started drawing with the strength of his shoulder, which was the only part of his body he could freely move,” explained Lee. Although he drew over 1500 pieces of art, he couldn’t make a living due to the lack of promotion and acknowledgment. Therefore, Lee, along with her teammates, created a platform that could become a sustainable profit model. They started off from scratch to brand talented individuals, solely with the concept of 'everyone has a special talent'. “We first started through naming the brand along with designing the logo. Since the platform we were planning to design was an individual rather than an enterprise, we had difficulties in systemizing it,” reminisced Lee. After studying illustrations for this job, she herself made a logo that configurates a person drawing on a wheelchair and created a facebook page to better advertise this brand. They also sold his work at the 17 Hearts Festival held in HYU to better advertise it. The logo of 'Artist Tak' on the left, and a picture of the postcards they sold in the 17 Hearts Festival on the right. (Photo courtesy of Lee) In accordance with Tak’s request, they are donating a certain portion of their profits to NEXON Purme Children’s Rehabilitation Hospital to help those facing similar difficulties. Throughout the interview, Lee showed her desire for Tak to continue on with this platform for his living even after this project ends. “I wish we could make a system stable enough so that he could carry on this project easily by himself,” wished Lee. Her final goal is to make a social impact with less priority in making a profit. Lee commented, “My final goal is to become a CEO of a social enterprise. As for now, whatever I do after I graduate, I want to be in a position where I could give a positive influence on the society.” Washing off your depression "Someone who had the same experience can better understand them." “I myself suffered from depression in my early twenties,” Yun started off. “I visited various counselling centers and attended in school programs to overcome my insecurities but suffered from recurrences.” She had a thirst for helping the students in similar situations and therefore decided to take a scientific and systemized approach towards this matter. She applied ‘cognitive therapy’ into a platform to help those with depression to acknowledge their own status and recover the symptoms through their own cognitions. She created a facebook page named ‘Mindful Laundry’ (click HERE) and provided three steps in this model. First of all, she created videos for an entry, then introduced a mental inbody test so that the testers could be cognitive of their own state. As the last step, she intends to make gatherings between people with similar symptoms, to provide positive synergy. Yun’s idea is already being acknowledged in the society. She won a prize through this idea in the SBCA (Social Venture Competition Asia) held on the 10th. However, her duty isn’t as easy as it seems. “I take care of all of the activities required to maintain this platform. I create and visualize all the ideas needed and manage the facebook page by myself. The biggest difficulty definitely arises from the lack of manpower,” commented Yun. She added that she wanted to continue on this project even after this semester to achieve her goal. “A lot of people are suffering from depression in the current society even though you don’t reveal that fact in the first place,” commented Yun. She wishes to become a cozy nest for those in need of help. The four students of the Social Innovation Lab. They are still in the midst of achieving their dreams. Continuing different projects with the same goals, all members of the Social Innovation Lab are still working day and night to change the world in their own ways. A society where people can live with a hope, a society where people can easily reach for a hand is what they will be working on. We always have a better tomorrow ahead of us, thanks to these students with motivation. On Jung-yun jessica0818@naver.com Photos by Kang Cho-hyun

[Culture]What Will We Leave Behind

In Korea, there is a saying, “A hide is left when a tiger dies, and a name is left after a person’s death.” In reference to this quote about life, the “Us, Here Forever” exhibition, in commemoration of the 30th passing year of singer Yoo Jae-ha, gives us all something to think about while cherishing the legacy that the late singer left behind. Held at the Hanyang Museum, located next to the International Department building, the exhibition began on November 10th and is planned to last until June 30th, 2018. Open to all students and visitors, it operates from 10AM to 5PM on the third floor of the museum. Recreating the life of Yoo Jae-ha The exhibition is part of a project called, “The People of Hanyang”, dedicated to celebrating and appreciating the people of Hanyang who had left their marks in the world. Yoo is the third person to receive this honor, following the late poet Park Mok-wol and Professor Lee Man-young. Park Mok-wol was an esteemed poet who left a myriad of verses committed to the depiction of nature and nostalgia, and Lee Manyoung was the very first Korean computer scientist. Yoo was chosen this year for his musical contribution to Korean culture. To give an introduction on Yoo, he is a celebrated singer of the 1980’s, who died in a tragic car accident. The death of the late singer was especially tragic for two reasons: his died at such an early age, and his immense musical potential was left unfulfilled. Having produced one album composed of nine songs, Yoo had written, composed, and edited the entire album by himself, which came as a shock to the musicians of his era. His work later became idolized by many musicians, and he is recognized for having led the Korean popular music culture to a higher level. Furthermore, the annual “Yoo Jaeha Music Contest” is another form of his continued legacy, which produces a number of musical prodigies every year. The exhibition displays a number of Yoo Jae-ha's old items. The design and production of the exhibition was done by the school, and it is composed of two parts. It was aimed to create an interactive platform where the visitors could take a step closer to the life and work of Yoo. The first part of the exhibition focuses on the life Yoo as a student of Hanyang, in the Department of Composition. The exhibition displays a number of pictures of him with his friends, professors, as well as his hand written application to one of the school’s guitar clubs. Furthermore, there is a written anecdote of Yoo’s school life, where he had turned in a piece of composition as an assignment. At the first look of his piece, the professor had shouted at Yoo for having plagiarized the work of Mozart. This incident shows just how talented he was at composing, and how much of his chords and passages resembled the works of Mozart. In addition, a recreation of his room during his college life takes a large proportion of this section. As an important background for the beginning of his musical career, his room is decorated with many albums of great musicians as well as his instruments. It provides a visual vendor where the audience can relive a part of Yoo’s life and feel closer to him. A letter written to Yoo by his mother is engraved in the wall of the installation, evoking deep sentiments from visitors. A corner is comprised of winners from the Yoo Jaeha Music Contest, each making their contributions in Yoo's memory. The second part of the exhibition is dedicated to his afterlife, when his music received the most attention. A display illustrates the establishment of the Yoo Jae-ha Scholorship as well as the Yoo Jaeha Music Contest, created by his father and now led by his brother. The Yoo Jae-ha Music Contest has been held every year since 1989 and continues to seek out and support gifted musicians. A corner provides headphones where visitors can listen to a compilation track of winners from the contest, singing their own versions of songs written by Yoo to express their appreciation towards him. Furthermore, there are visual projections of Yoo’s performance in a televised music program as well as clips of winners of the Yoo Jaeha Music Contest. Behind the scenes Through an interview with the Hanyang Museum curator, Choi Hyo-young, it was revealed that the piano, guitar, LP tracks, and photos of Yoo Jaeha were provided by his family through the Yoo Jae-ha Scholarship Committee. She expressed that the most difficult part of the exhibition preparation was the lack of available data and materials due to Yoo’s short life and career, and the contributions made by his family were a great help in the process. She added that although Yoo’s music was somewhat quiet and gloomy, he was a funny and energetic person in real life. She hopes that people can get to know more about Yoo as a person and is happy to see that the exhibition is drawing a regular number of visitors. The street performance played a list of Yoo's well known tracks. As a part of the promotion for the exhibition, a street performance, or busking, was held by music clubs of Hanyang, where students sang the songs of Yoo. It drew a large crowd despite the biting cold and was deemed meaningful to the audience as well as the performers. One of the performers, Kim Won-il (Clothing and Textile, 1st year), commented that although he had always liked Yoo as a singer, he was not aware that Yoo went to the same school as him. As a fellow Hanyang junior, he felt proud to have been given the opportunity to perform in his celebration. On behalf of the museum, Choi expressed gratitude towards the performance, appreciating the students contributions and how they interpreted Yoo’s music in their own ways and shared it with the audience. “Overall, I think a lot of students feel pressured about visiting the museum. I hope this exhibition can lighten the image of the museum and attract more students. There are a lot more things for them to experience.” Lee Chang-hyun pizz1125@hanyang.ac.kr Photos by Choi-Min-ju

[Academics]Conducting on a Sturdy Building

The current society is suffering from various natural and man-made disasters starting from terrors to earthquakes, such as the recent earthquake that panicked the citizens in Pohang. When a strong impact is made upon the ground, buildings require enough solidity to endure damage in order to protect the people. For a stronger, safer building, professor Yoo Doo-yeol (Department of Architectural Engineering) introduced an improvised concrete in his paper, ‘Effect of fiber geometric property on rate dependent flexural behavior of ultra-high-performance cementitious composite’. Yoo wishes to make sturdy structures for the citizens' safety. Most buildings are made of concrete, and it takes a huge part on the safety of a building. Concrete is initially vulnerable in tension, so there are already improvised versions of concrete commonly used in North America. The new model contains Micro steel fibers within the concrete to prevent the concrete from breaking into two big pieces. Through the steel fiber, the concrete only results in having micro-cracks even when a sudden weight is stressed upon the concrete. In this already improvised concrete, Yoo made a further research to strengthen this concrete in both quasi-static (a state in which something is almost still, but not completely) and impacted states. A ‘quasi-static’ state refers to an ordinary state with only mere impacts such as the vibration of footsteps everyday. These two states require a different sturdiness for different purposes, and the researchers concentrate on improving both of these conditions. Yoo focused on the aspect ratio of the micro steel fibers installed in the current improvised concrete. Aspect ratio is a numerical figure of the division of the diameter from the length of the fiber. Once this aspect ratio was changed in a quasi-static state, Yoo found out that the solidity was maintained and the energy absorption force was strengthened even when the amount of micro steel fibers were reduced. With the same amount of micro steel fibers with the changed ratio, Yoo was able to discover that the energy absorption force almost doubled within a shocked state. The results made through different aspect ratios. Micro-cracks can be seen within the pictures. (Photo courtesy of Yoo) Yoo emphasized the importance of this improvised matter. “Protecting the citizens within the buildings is becoming an urgent matter as countless accidents are occurring more frequently. The current structures lack enough safety to minimize the loss of lives.” The breaking of cement is distinctly more critical than the cracks in cement. Therefore, thorough research is required to make a sturdy building. “We had difficulties in capturing the process when the cement was impacted,” reminisced Yoo. The test cement is fully demolished within 0.001 second (a millisecond), and he had to capture all of the procedures within that millisecond. No kinetic equipment is available in Korea. As a result, he had to proceed with his research research by using the equipment from the University of British Columbia. Despite their mechanical hardships, Yoo made an innovative result in the field of architecture. 2017 is only his second year as a professor in Hanyang University. As the field of architecture is conservative, his final goal is to make practical application with his research. “Various factors such as durability and energy absorption force need to be considered when building a structure as it is directly related to the people living inside the building. This is only the beginning. I still have a lot more factors to work on, but I will continue my research enthusiastically until my studies can be applied to daily structures,” commented Yoo. Yoo will continue on with his goal to make a practical application with his discovery. On Jung-yun jessica0818@hanyang.ac.kr Photos by Choi Min-ju

[Academics]Advent of Geometrically Controlled Micro-tissue

When certain parts of a human body are damaged, the only treatment is to take medication to either halt the worsening or alleviating the agony. However, medical technology to fully recover the organs by developing thermally expandable hydrogels (a network of polymer chains that are hydrophilic, often used for the care of wounds) is becoming potential. Professor Shin Heung-soo of the Department of Bioengineering has lighted upon the possibility to control the cell patterns to harvest geometrically regulated micro-tissue through his research “Microcontact printing of polydopamine on thermally expandable hydrogels for controlled cell adhesion and delivery of geometrically defined microtissues.” Shin has been researching in the geometrically controlled micro-tissue field for 20 years, attempting to discover the full recovery of human tissues and organs. The fundamental finding of this research is that human cells can function through metabolism and, thus, can also generate spontaneous curative powers. “The main theme of our research is that we discovered our own method to discharge the damaged cells and entirely recover and replace them back to where they belong,” said Shin. The research team utilized the hydrogels to transfer the cells by patterning the polydopamine. PD (polydopamine) is an important substance in this research which is formed by oxidation of dopamine often used for coating various surfaces. Until now, the medical industry’s best option to treat damaged cells or organs made up of them was to inject cells floating inside a culture fluid (the fluid used as a medium for growing microorganisms). However, Shin’s research is now stepping ahead to actually maintaining the patterns and shapes of actual cell structure and transferring them into the human body. “My research can resemble the method of a paper tattoo. When you get a paper tattoo, you apply a paper with a desired picture, drop water on it, and, after some time, the picture is embedded onto the skin cells. My discovery works the same way in that the paper is hydrogel,” stated Shin. The main focus of this research is that not only is the hydrogel transferring the basic patterns but also shapes. The transfer of shapes in the three-dimensional form, requires a specific code and environment of the cells’ patterns and placement. Through experiments with artificial models and mice, the research was proven to be valid in that micro-tissues were readily translocated in vivo to the subcutaneous tissue of mouse. A diagram of Shin's experiment proves that micro-contact printing of polydopamine on hydrogels has worked out by the successful transfer. (Photo courtesy of Shin) This extensive research took one year to complete by Shin and his two doctoral students. The research began with their considerate worry concerning the aging society. “As the population is aging with a higher average life expectancy, people are constantly suffering from chronic diseases and degenerative conditions. To solve this problem, instead of stopping diseases from worsening, I began this research,” said Shin. Before Shin’s research, the only possible method to entirely cure or recover damaged organs was by internal organ transplant. However, the medical and technological fields can now expect to cure endemic, chronic diseases eternally. “I have researched in this field for about 20 years under the belief that science and medicine will be able to treat humans for good,” revealed Shin. "Discover your own path that nobody has walked on. You will be able to find the light when your ideas are developed with your efforts and concerns!" Shin’s ultimate hope is to furnish his developed micro-tissue technology to easily accessible places like hospitals and pharmacies. “In this Fourth Industrialization era, I can now graft new technologies like 3D printing skills or big data to produce efficient and exquisite results,” emphasized Shin. “Even though South Korean society highlights the importance of living a stable, routinized life, I believe that our Hanyangian students have inexhaustible ideas and potential. I hope our future generation will be able to utilize their ideas and dream bigger!” Kim Ju-hyun kimster9421@hanyang.ac.kr Photos by Kang Cho-hyun

[General]Fusion Major 101

Hanyang University Social Innovation Center is carrying out the initiative called “HUGE (Hanyang University for Global Engagement)”, which aims to help the youth become a true global leader in accordance with the founding philosophy of "Love in Action". It attempts to foster global leaders who practice the spirit of sharing by facing global social issues and resolving them. Fusion majors is one of the means by which innovative global leaders are fostered, by opening new perspectives and enagling them to lead the society into an innovative direction. What is a fusion major? Fusion majors are majors established by combining courses of preexisting majors or departments, marked as the second or the third major of the student. The currently established fusion majors on the Seoul campus are as follows: Humanities Transdisciplinary Studies (consisting of Art Technology, Technoscience Humanities, Digital Storytelling, and Engineer Communicatiton), Humanities-Software Convergence, Public Administration Humanities, Chinese Economy and Trade Program, Global Business Culture, Classical Reading, Business Foundation, Automobile Software, and Big Data Science. As for the ERICA campus, there is Global Strategy Communication, Design Engineering, and Software for Emerging Technology. Fusion majors are innovative in the way that they can help students become outbound experts, encompassing comprehensive knowledge from different perspectives rather than an inbound single viewpoint. Although it may sound similar to double majoring, there is a distinction between the two. While the former is the studying of two separate majors at the same time, the latter introduces the two different fields in one bowl, combining different majors and creating an innovative one. By combining different fields, fusion majors offer a multiangular perspective. (Photo courtesy of CIO) “I am double majoring in Chinese Economy and Trade Program because I wanted to study further and deeper about China aside from the studies in my first major, digging more into the politics and economic aspects of the country. I want to recommend this major to others who are interested in China because it enables you to comprehend the country from an acute viewpoint,” answered Jung Jae-woo (Chinese Language and Literature, 3rd year). According to Jung, the fusion major enables him to acquire knowledge not provided in his first major from an innovative, integrated perspective of different majors, which truly helps him dig deep into the root of the expertise. “It’s also possible that the fusion majors becomes a separate department in the future, depending on its performance. And there is no restriction or regulation to foreign students, as the same rules apply to all students. Fusion majors are for anyone who wants to become an innovative global leader!” noted Lee Won-gurl from the Center for Creative Convergence Education. He added that the greatest advantage of fusion majors is the convergence of different fields, going beyond the boundaries of each domain and creating an outlook of integration for the next level. Fusion majors can open the career path to unfixed routes, from Humanities to Engineering, for example. Lee believes fusion majors could open unprecedented career paths. Some FAQ’s! When considering double majoring, students often come up with one or more of the following questions: Q: I am a double-major student, and what happens if I cannot fulfill the graduation requirement in time? A: You will be disqualified if you fail to fulfill the requirements. Taking seasonal courses can be an option. Q: If I am an ERICA campus student, and I applied for a double-major on the Seoul campus. Which campus do I belong to? A: Those who have successfully fulfilled the requirements in the 4th year will belong to the Seoul campus under that situation. In other words, when finishing the courses of your second major, you are a Seoul campus student. However, after completing the course, when going back to your first major, you will receive your degree on the ERICA campus. Q: What will my graduation certificate look if I double major? A: Your first and second major will appear in parallel on your graduation certificate. In terms of the certificate paper, you will receive separate papers for your first and the second major.

[Academics][Excellent R&D] Kim Doo-seop (Department of Sociology)

As of last year, there were more than 1.71 million foreign residents in Korea, which is 3.4% of the total population. The number of marriage migrants, also known as multicultural marriages, is also a large part of the total population at around 150,000. Professor Kim Doo-seop (Department of Sociology) has built a foundation for migrant research since establishing the ‘CSMR Multiculture Institute’ in 2011. This year, Hanyang University SSK Multicultural Research Project was selected as a project to enter the large-scale stage. ▲On the 6th, News H met Professor Kim Doo-seop (Department of Sociology) and discussed the contents of the SSK multiculture research project and the selected items to enter the large-scale stage. An ongoing process of building data on foreign migrants Unlike conventional wisdom, Korea is becoming a country where various cultures coexist. As mentioned above, nearly 4% of the total population are foreign residents or marriage migrants. Socio-scientific research on this phenomenon is crucial but various data such as related literatures should be preceded. Since 2011, Professor Kim's research team has built a foundation for migrant research through archives and database construction. In addition, he published four academic books on marriage immigrants and migrant workers, ten books on foreigners' statistics, and 54 papers in domestic and international journals. He has also internationally carried out other academic activities such as academic conferences, joint seminars, a colloquium, and academic presentations. Recently, as a result of the examination by the Korea Research Foundation, the SSK multicultural research project of Hanyang University was recognized as a significant research project with its importance and timeliness and selected as a large-scale research progect. This selection has been applied since last September and will receive research funds of 580 million won per year over the next four years. The name was also changed from 'CSMR Multicultural Institute' to 'CSMR Multiculture Management Center'. Professor Kim 's research team will expand the research project. A leap forward as a hub for immigrant and multicultural research First, the archive for migrants and DB construction, which have been done in the past, will continue to be supplemented. By August 31, the research team has collected about 1,300 related papers in the CSMR archive and will be adding future papers and constantly supplementing the search menu. The research subjects have also been expanded to set targets for collecting data on ethnic minorities abroad. Until now, archives and databases have been organized mainly on problems related to domestic issues such as multicultural families, marriage migrants, migrant workers, multicultural children, foreign students, etc. By expanding the study's target groups and diversifying the construction data, the center pursues stepping up to a global DB center for multiculture. In addition, the center plans to expand exchanges with scholars and research institutes in Korea and abroad and also exert their active efforts to nurture students by linking with the in-school research institute and graduate school curriculum. In line with the name of the Multiculture Management Center, they will ultimately make a leap into the hub of multicultural research and immigrants who have formed networks with major research institutes and scholars in the world. ▲ Professor Kim Doo-seop said, "We will contribute to policy alternatives and social consensus through future research." Professor Kim said, "The center provides a center for research on migrants through document archives and DB construction" and added, “It is meaningful to promote research through various interdisciplinary approaches and to form an international network of migrants and multicultural researchers. " Furthermore, he stated that the ultimate goal of the study is to contribute to the accumulation of demographic knowledge on migration and multiculturalism that Korean society faces and to provide policy alternatives and social consensus through ongoing activities of the Multiculture Management Center.

[Academics][Excellent R & D] Professor Lee Sang-hoon (Department of Biochemistry and Molecular Biology, College of Medicine)

Chronic diseases, such as Parkinson's disease, diabetes, dementia, and degenerative arthitis, cannot be cured and should be managed for life. To treat this, stem cells are being studied in medicine. Professor Lee Sang-hoon (Department of Biochemistry and Molecular Biology, College of Medicine) has been conducting research on embryonic stem cell research for treatment of chronic diseases at the Medical Research Center (MRC) of Hanyang University since 2008. He will carry out further research until 2024. ▲ On November 6th, News H visited Prof. Lee Sang-hoon (Department of Biochemistry and Molecular Biology, College of Medicine) and talked about stem cell and tissue regeneration research. (Source: Professor Lee Sang-hoon) Increased understanding of stem cells The relationship between chronic diseases and stem cell research is inevitable. First, in order for the disease to be treated, it is necessary to restore the cells that have been damaged by the disease. The reason why chronic diseases are not treated is because the damaged tissue is an organ that can not be recovered by the human body itself. Neurons and brain cells are destroyed, or genetic problems do not occur due to specific hormones, making a cure impossible. But there is a possibility. If the patient's stem cells can be cloned and cultured well, the cells can theoretically be differentiated into desired cells. Professor Lee has studied the theoretical techniques in detail. In 2008, Hanyang University MRC (Medical Research Council) conducted a research on the basic mechanism of stem cells under the name 'Stem Cell Control Research Center'. In detail, stem cells are cultured, and the number of stem cells is differentiated into tissue cells. Professor Lee conducted a 'stem cell behavior control study' that controlled this behavior. Since the study of stem cells at the time was at the beginning stage, he has been working on the mechanism of how a series of processes take place. Based on the research, he will carry out this research project. First of all, this research project will continue the basic mechanism research. In addition to the existing understanding, he will improve the understanding of stem cells, the understanding of the differentiation process, and the plan to apply it to other fields such as stem cells. ▲ Professor Lee's team will continue to study for higher stem cell understanding. (Source: Professor Lee Sang-hoon) Clinical application, industrialization and internationalization Through this project, his research team will receive a total of 7 billion research grants for seven years, one billion annually. As a new name, Hanyang University MRC 'Tissue Regeneration Promotion Research Center's goal is to develop cell transplantation and gene therapy technologies for Parkinson's disease, mass-production of stem cells with excellent therapeutic effects, and research on the development of affected parts using astrocytes. Parkinson's disease causes the destruction of dopamine-producing substantia nigra, which is intended for clinical application of cell transplantation or gene therapy. Mass production of stem cells can be used for clinical treatment, so mass production and industrialization are also important targets. Finally, research using stellate cells is also an important goal. When diseases such as dementia or Parkinson's disease are destroyed, not only the destroyed cells but also the surrounding environment becomes bad. Some of the environment is astrocytes. By transplanting stellate cells made by differentiating stem cells, it can improve the surrounding environment of the brain and help regenerate brain tissue. In this way, internationalization of research results through clinical application and industrialization process is being prepared. In addition to the domestic medical industry, it is also possible to enter the overseas markets in cooperation with Indonesian companies. In addition, research on the basic mechanism will be carried out continuously, so that degenerative diseases, which were chronic diseases in the future, will be gradually transferred to the treatment side.

[Notice]Expressing Out Confidence in Korean

“I have a Korean presentation a few weeks later, and I have no idea how to prepare for it.” This is a common concern among international students in Hanyang University (HYU). Along with the increasing number of international students in HYU, various programs are being created to help these students. The Intensive Korean Writing Class (IKWC) is a special program made solely for international students by the Center for Creative Convergence Education, for those having problems writing in academic Korean. News H attended the first class of the second semester to take a closer look. IKWC, a stepping stone for international students As international students in HYU, they inevitably have to go through an obstacle of a language barrier. This could happen both in daily living and in lectures. However, a lot of these students recall their Korean assignments as the most difficult. When writing, various literacy expressions along with the correct grammar have to be considered. This makes writing for the international students a cause for repulsion. “Grammatical problems aren’t the only problems international students go through. They have difficulties with applying the unique traits only Korean has. I try my hardest to teach them these characteristics so that they could freely use them in their assignments,” commented Oh Se-jin, a lecturer from the IKWC. Oh gave an enthusiastic lecture to the students. “The most important element when writing is considering the reader. In your cases, it would be the professor,” Oh started off. She explained the overall curriculum of the class, dividing writing into the distinction of the literary and colloquial style to writing reports and resumes. The lecturer kindheartedly gave similarities and differences between Korean and the students’ mother tongue. “I believe that both spoken and written words have the power to move a person. So I tend to emphasize sincere writing and speaking when I teach. I wish the students would not fear writing in Korean by the time this class is over,” said Oh. Various reasons have brought these international students with different nationalities to this class. Zhang Yang Yi (Business Administration, 1st year) from China explained, “I don’t have any difficulties when writing in Chinese. I can write in long sentences including all I want to say, but it’s the opposite in Korean. I simply can’t think of what I should write when writing a report in Korean.” Another Chinese student, Zuo Jia Yu also expressed that she had difficulties with her vocabulary. “I first started learning Korean two years ago when I first entered this university. I had problems with Korean grammar and vocabulary during lectures, so I intend to improve my vocabulary skills through this class.” The students also concentrated through the whole class. The Center for Creative Convergence Education Behind this helpful program, a lot of effort was made by the Communications Clinic in the Center for Creative Convergence Education. This Clinic was constructed in 2012 to develop the Hanyangians’ creativity and their communicative competency. This center manages not only this IKWC, but also various programs such as the communication clinic, future humanities forum, debate competitions, English film festival, and English quiz nights. The communication clinic is the foundation of IKWC, allowing all Hanyangians to receive help in four languages – Korean, English, Chinese and Spanish. This center is working hard for the improvement of creativity and communication skills, and a lot of students are receiving help from it. The IKWC made its first step last year, made by the request of the Office of International Affairs, due to the need for academic help for international students as HYU is a globalized university. International students require a certain ability with their Korean writing skills to proceed with their academics in HYU; therefore, there was a need for a program that could help them get to a certain extent in their writing of Korean. The first year of the IKWC, therefore, came to an end with great satisfaction for international students. This second IKWC this year is already almost full of students wishing to improve their Korean skills, and they have started their first class off successfully. Students can receive their counciling in these rooms. (Photo courtesy of Communications Clinic) Chan Puthearath from Cambodia commented, “I have a Korean presentation two weeks later, and I wish I can prepare it well to give a great presentation. I don’t want to be a harm to my Korean teammates, and I will do my best!” Anyone who is in need of help with their language skills, whether it is Korean, English, Chinese or Spanish, can freely visit this clinic and receive help. Why don’t you visit the clinic and express your confidence in the language you wish? On Jung-yun jessica0818@hanyang.ac.kr Photos by Kang Cho-hyun

[Academics]Making a Heat Storage Device

Professor Kim Dong-rip (Electrical Engineering) is one of the many scholars of the field who seek to create a new material that can efficiently store and release heat energy. His new approach of integrating metal or graphene with erythritol, a phase change material, was a significant breakthrough in this endeavor. The details of his research, "Fabrication of three-dimensional metal-graphene network phase change composite for high thermal conductivity and suppressed sub cooling phenomena" were kindly explained to a great length by Kim. Introduction to Kim’s research field To simplify Kim’s research, it is conceptually an attempt to create a “heat” battery. Just as the common battery stores and provides electricity, Kim is in the process of creating a heat storage device that can absorb and release heat. The underlying motive of this research was the observation of an irony in two types of industries; one field focuses on cooling temperatures, while the other endlessly work to bring temperatures up. For example, a car factory uses a significant level of heat in shaping and wielding various car parts. However, this heat needs to be constantly in check, since overheating of the factory can cause extreme dangers. On the other hand, a facility that provides heat to households are in forever need of more heat to circulate. Now imagine a device that can absorb the heat from the car factory and deliver it to the heating facility. Kim’s three-dimensional metal-graphene network provides the foundation for what material this device will be made up of. Kim explaining the details of his research This field of technology has received a great deal of attention from the international society in recent decades. Similar to Kim, most scientists turn to the development of a new material for achieving efficient heat storage. The three key standards that a heat storage material or a heat storage device must have, are high energy density, high conductivity, and stability. Historically, the traditional material used for this purpose was water, which lacks efficiency in all three standards for commercial use. To elaborate on these standards, energy density refers to how much energy a material can absorb and retain, which in this case would be heat. High conductivity is the speed at which the material can pass on the energy, vital for efficiency in terms of time. Finally, stability is the ability for the material to maintain its’ initial form after repeated use. As the nature of the material’s task involves repeated heating and cooling, it is imperative that there is no degradation after use. Current research in the field has made somewhat a progress concerning energy density, but has not seen satisfactory achievement in the two other standards. The distinction of Kim’s breakthrough The title of Kim’s research explains the breakthrough in this area word by word. Quite bluntly, he has succeeded in the "Fabrication of three-dimensional metal-graphene network phase change composite for high thermal conductivity and suppressed sub cooling phenomena". In the other term, Kim has found a way to create a material (phase change composite) out of metal and graphene, that has high thermal conductivity and stability (suppressed sub cooling phenomena). The term, “three-dimensional” refers to the manner in which metal or graphene is spread throughout this material. The reason for the use of metal was due to its’ high thermal conductivity and general use in the field of mechanics. However, the problem with metal was an inefficient level of energy density. To overcome this limitation, a material called erythritol was introduced. Erythritol is a phase change material (PCM) that is characterized by high energy density and conductivity. It has received a wide range of attention from scholars of various fields for its’ endless potential for utilization. An illustration of how the new material was formed (Photo courtesy of Professor Kim) By mixing granules of erythritol with metal paste and subjecting it to hot pressing, a new material composed of 3D metal network was made. This alteration of metal had high energy density, high thermal conductivity, and stability. Furthermore, the same experiment was done using a material called graphene, which had similar results. Specifically, a 3D graphene network had 95% of energy density as pure erythritol, and thermal conductivity was 4.7 time higher than the conventional graphene. As for stability, experiments were carried over 100 times to reveal that the network was stable and the material solid. Furthermore, the metal and graphene network has high flexibility, which indicates a wide scope of utilization methods while maintaining endurance. In fact, this network is stable enough to be put into commercial use right away, and Kim is currently working with different research facilities and companies to explore how this new material can be put into use. The significance of the results Ultimately, the efficiency of this newfound material will contribute to environmental preservation. As previously mentioned, some industries strive to create heat, while others try to release it. Linking these two fields will create a symbiotic relationship that can also reduce energy costs and help preserve the environment. For example, the average car emits the greatest amount of polluting gases in the process between ignition and waiting for the car to arrive at a certain temperature. If we could use a device that can heat the car up, these gases would decrease significantly. Even electric cars, this heating process is very significant cost of energy. In the end, it all comes down to energy efficiency, which Kim has made a great contribution to. Kim described the positive mind as the ability to find the smallest good thing in the midst of a depressing situation. In retrospect, Kim pointed out that having a positive mind had been the most helpful support in carrying out his research. When others fall into despair after repeated failures, a person with a positive mind tries to find the silver lining in all of these moments. Kim emphasizes this virtue in all aspect of life. He was especially concerned with many of the students who came to him for counseling. “Today’s students often feel that they are not enough. When writing resumes and giving self-introduction, they feel that they lack fancy achievements to make them stand out”. However, once he gets to know them, they all have distinct talents. Kim explained that seeking room for improvement is indeed important, but to the extent of self-criticism is poisonous. The one thing that he wants to tell his students is that the greatest drive for success is the positive mind. Lee Chang-hyun pizz1125@hanyang.ac.kr Photos by Choi Min-ju
