[Academics]What Makes People Prosocial

Have you ever wondered what makes some people particularly social and not others? Kim, Sanghag (Department of Sociology) tried to identify the relationship among empathy, attachment to parents, and prosociality. Prosociality refers to behaviors that are intended to benefit others. Kim mentioned that there was not a lot of research done to figure the relations among the aforementioned three aspects of human psychology. To make matters worse, research on empathy predominantly focused on older children from around 11 to 15 years of age, as morality was conceived as a cognitive process. Kim is enthusiastically explaining about his work. That focus has recently shifted to younger children – as young as just a few months old – and the findings in the differences in emotional empathy at such an early stage have emphasized the importance in the influence of nurture on empathy and the prosociality of a person. Kim stressed that one of the strengths of his recent paper titled, ‘Relational Antecedents and Social Implications of the Emotion of Empathy: Evidence from Three Studies’ is the quality of data that the team has collected over the course of 12 years. In order to discern the link among empathy, attachment, and prosociality, the research team had used three forms of studies: family study, play study, and the parent-child study. In the studies, a child’s empathy for either the mother or father was elicited under a scripted, stimulated distress paradigm, where the parents acted upon a detailed script to see the child’s reaction. The entire process was recorded for later coding, capturing the child’s expressions of emotion through facial, verbal, and behavioral means. The child’s attachment security was measured under the Strange Situation Paradigm (SSP) and the Attachment Q-Set. In the former measure, the child was left with a stranger and the action was analyzed through coding; while in the latter measure, the parents were asked about the attachment security. The last and probably the most important measure, the child’s prosociality was measured in a peer context in order to determine whether the child took turns when playing, askings for things nicely, and so on. The solid line represents a significant effect, and the dashed line represents a nonsignificant effect. Graph A represents the mother– child dyads and B for the father– child dyads. Further explanation is below. Photo courtesy of Kim Through such vigorous research from middle class families with various educational and ethnic backgrounds to high risk families with financial issues, Kim and the research team were able to draw lines between the factors. Attachment here turned out to be a moderated mediation. Moderated mediation is a statistical term where the effect of an independent variable A on an outcome variable C via a mediator variable B differs depending on the levels of a moderator variable D. In this context, the effect of ‘empathy’ on the outcomes ‘prosociality’ depends on the level of the moderator's ‘attachment security’, as you can see in the graph. There is an arrow pointing to the solid line between empathy and prosociality. What is surprising about the finding is the impact of empathy on prosociality, which is stronger when the attachment level is lower. This goes against the common perception that the better the relationship between the parents and a child, the better the child behaves in society. However, this does not necessarily mean that children are more prosocial when they have a bad relationship with their parents, but that the impact of empathy is noticeably stronger under an undesirable context. “This research will provide supporting evidence that prosocial behavior and empathy is at least partially due to the environment, as infants are a good subject to see the effects of nature and nurture. They do not have any other contaminating factors that the researchers have to take into account,” said Kim. "Don't be afraid to take the path that nobody else chooses. With the know-hows acquired from the deserted place, you will be able to succeed in the well known fields too," encouraged Kim. Kim, unlike most social science researchers, is highly interested in what induces positive aspects from people such as happiness, morality, and identity. “Social science and social psychology to be specific, are great tools in explaining to me and the people around me. What we feel, acknowledge, and learn is what makes this area so fascinating for me,” smiled Kim. He plans to continue his research further on the three key words both in Korea and in the United States. Kim So-yun Photos by Choi Min-ju

[General]Hanyang Trail-Doolehgil Recreated on Our Hands

Hanyang University is known to have many hills, making the two-dimensional map less useful. It is not hard to encounter a visitor or a freshman on campus asking for directions year-round. The Industry-University Cooperation Foundation and the Wooyang Cooperation joined forces to develop Smart Doolehgil last April, which had its opening ceremony on December 12th. On Friday, January 9th, the team joined the 2018 College Lab Technology Start-up Demo Day in the Coex for the demonstration. News H joined the event to further explore the Smart Doolehgil. The Smart Doolehgil application is running on a tablet. The application can be downloaded from the Google Playstore. Visitors, freshman, and the visually impaired Doolehgil is a Korean word that refers to a walking road that goes around something. The Hanyang Doolehgil, therefore, refers to Hanyang’s eight scenic points and the roads that connect them. A 2.6km-long trail that passes through the campus covers major historical monuments and buildings of Hanyang. The trail provides a restful environment for people and an opportunity to see the whole Sungdong-gu at a glance. Unfortunately, there are some people that cannot join the majority due to their visual impairment. Smart Doolehgil provides guidance to those who are not familiar with the campus but mainly for the visually impaired. “We are always interested in corporate social responsibility (CSR) and have the technology to provide better guidance,” said Kim Jin-hong (Chemistry, '85), the CEO of Wooyang Cooperation. Smart Doolehgil was created with Wooyang Corporation’s technology in making beacon devices combined with the Hanyang Industry-University Cooperation Foundation’s data processing technology. A beacon is an intentionally conspicuous device designed to attract attention to a specific location. More than 350 beacon sensors planted on campus are now working as the new guide dog. Kim Jin-hong (Chemistry, '85), the CEO of Wooyang Cooperation, is enthusiastically explaining the background story of the Smart Doolehgil system. For better mobility With the smartphone application and a shoe sole, the visually impaired or individuals with very poor vision can locate buildings, ATMs, and bathrooms. A pair of location devices is embedded in the specially designed shoe sole, and vibrates in the direction where the person has to move to. For instance, if a walker needs to turn right at a corner, the sole in their right shoe vibrates. The device also lets the user know whenever he or she is facing a staircase, a hazardous place, or has arrived to their destination. The smartphone application is used together with the device to provide verbal instruction. Both Kim and Jang Gi-sool (Manager, Industry-University Cooperation Foundation) mentioned that Kim Hee-jin (Management, 4th year) helped a lot, especially in giving insight from the perspective of the visually impaired, from what they need the most in order to enhance their mobility. She also contributed in choosing the location of the device to be inserted in the shoes, where it was least apparent from the outside. Other options, such as the wrists or neck, would have discouraged the handicapped from using the system. The shoe sole vibrates to alert the user about the direction or any hazards. The product has not yet been placed on the consumer market as it is still under development. The Smart Doolehgil, however, is accessable only via the smartphone application. “We still need more progress. The most important thing is the preciseness, as many blind people cannot find the entrance of the building even if they succeed in finding the building itself. The more accurate it is, the better,” mentioned Kim. The Smart Doolehgil’s opening ceremony was in December, but the system is constantly developing based on user experience. Both the Wooyang Cooperation and HYU plan to exhibit the technology to the mass market during the upcoming entrance ceremony in March when the need for an accurate map and guidance system within the campus is at its highest. Kim’s ultimate goal is to grow his company as a social enterprise. With the success of the technology within Hanyang University, the Wooyang Cooperation will expand the system to roads and buildings outside the campus, yielding even better mobility for the visually impaired.

[Academics][Researcher of the Month] Calculating the Effects of the English Rule and American Rule

Have you ever lost a lawsuit? There are two ways to resolve the financial issues concerning legal costs after the resolution. The first method is called the English Rule, where the loser of a lawsuit pays the winner’s legal fees. The other one is the American Rule, where each party handles their own legal cost. Since the 1990s, there has been a general consensus among economists that the former improves the quality of a lawsuit and reduces trial costs. Yoon Jung-mo (Professor, Department of Economics & Finance) was the one to propose the question, ‘is it really?’ in his recent article, ‘Estimating the Effects of the English Rule on Litigation Outcomes.’ When asked if he has anything to tell his pupils, Yoon said, "you are all doing excellent, so I wish you can stop worrying," with a warm smile on his face. Every government aims to reduce the number of lawsuits, especially Korea and the United States. The increased number of court cases lead to increased government and societal spending on legal institutions and its personnel. The key to amend such issues is to reduce the real number of law suits to alleviate the burden of the court and increase the case quality, which is determined by the chance of a plaintiff winning the case and the amount of the settlement. Therefore, according to the long research in the economics field that concluded the English Rule, a lot of people argue for the rule. Currently, Korea is running based on the American Rule, but the law limits the amount of money that can be covered by the loser of the case. The prevalent textbook conclusion is mostly derived from the comparison of the Florida case, where they switched from the American Rule to the English Rule in 1980 and then flipped back in 1985. Because measuring the economic impact of a legal system can sometimes look like comparing apples to oranges, the case of Florida provided the perfect background for legal economists to analyze the impact. Yoon mentioned that there are two main significances that the paper proposes. First is that there are more proofs accumulated after the 1990s when the consensus was initially made. The initial paper studies the cases before 1980 and cases between 1980 to 1985. However, it neglected the cases after the second change of the rule, which could have critical impact to the interpretation. Also, Yoon and his co-author implemented a new way of making a conclusion. Traditionally, the economic impact is measured and reported as a fixed number. However, this cannot entail all the complex probabilities behind the result. Using the bound analysis method, researchers can predict the best and worse case scenarios and give a range of possible influences. The second significance is that Yoon and his co-author took the cases that were settled during the process into account. As only a few litigations continue to the very end of the judicial process, it is very important to consider the changed behavior of people according to the increased or decreased amount of pressure resulting from the verdict. Yoon is enthusiastically giving an explanation about his paper. Yoon’s scrutinized analysis, however, contradicts what has been believed for a long time. When it comes to the trial outcomes, the range derived from the bound analysis does not signify any relevance between the change of legal system and the trial cost. It does increase the amount of settlement, while decreasing the number of settled cases. “The hardest part of continuing such rigorous research was to overcome the constant skepticism,” said Yoon. According to him, it takes a long time for a researcher to complete a paper and for the paper to be accepted in a journal or presented in a conference. Believing in himself and moving forward regardless of the incredulity, Yoon will continue further to conduct research. Kim So-yun Photos by Kang Cho-hyun

[Event]Share Your Warmth Through Marketplace

Christmas carols are already playing and the Salvation Army’s bells are ringing in the streets. Holiday season is coming and it is warming up people’s hearts as well. Volunteers and donations are increasing, and ‘HY Global Market’ in Hanyang University, last Monday, was also one of the ways to give a hand to the community. Hanyangsians are taking a look at the items sold in the market. On an extraordinarily cold Monday morning recording -6.1℃, a number of students from WE-HY (Women in Engineering at Hanyang Center) supporters and engineering international student body was setting up the flea market in front of the Engineering Building 1. Newly established this year, WE-HY center aims to provide adequate programs and support for female students in engineering to get a head start into the world. The HY Global Market is one of the events organized by the center and planned out by the supporters. “We were worried that there might not be many donations made because people have to look for what they don’t use, clean it, and carry it all the way to school,” smiled Jung Yewon (Chemical Engineering, 2nd year), a member of the WE-HY supporters. Despite the concerns, there were more than 300 items listed on the market that day. “We spent more than half a day sorting the donated goods. We are so grateful for all the donors,” said Jung. Left: Jung Yewon (Chemical Engineering, 2nd year), right: Choi A-jung (Electronic Engineering, 2nd year). "We never knew such events in school take so much time and effort. Still, We want to participate more in other events, too." A passerby is taking a look at the items. People were peeking around the marketplace even before the official opening, which was at 11 am. Most of the products were second-hand from the dolls and clothes section, but many were new from cosmetics and accessories. One of the specialties of HY Global Market was that all of the accessories were hand-made by one of the supporters, Choi A-jung (Electronic Engineering, 2nd year). String-bracelets were also made by the organizers, stitch by stitch. All of the accessories in the market were hand made by the orginazers. The red tag means they are 5,000won each. Most items were sold at a very affordable price. One student who bought some makeup mentioned "the itmes were so cheap, and the fact that my money is donated to a good cause made me feel really good." Another specialty was that the products were sold at an unbelievable price. For example, a brand-new hand lotion was sold at 1,000won, and a 100% cashmere muffler was sold at 20,000won. When asked who donated the most, Kim Sung-ha (WE-HY center, researcher) answered “the executive president donated a lot. The mufflers that sold out within the first five minutes of the opening were also donated by the president.” Bila and a student from WE-HY supporters are making dalgona. A dalgona was given to people who purchased anything in the market. Just like the traditional way, every dalgona was stamped with a shape. If one manages to break the candy without hurting the shape, they are given a pair of 'night time socks'. 'Night time socks' are also part of a Korean culture where we heat the floor. The socks are made of soft and cozy cloth that warms up your feet when sleeping. The board on the right explains the string bracelets: they are hand-made by students and sold for 1,000won. It also mentions that all profits have been donated. The WE-HY center hosts lots of events such as ‘gender sensibility episode contest’ or ‘female engineer seminar’, but HY Global Market is the first one to engage international students. Recruited by friends, acquaintances and official posters, international students also had a lot of fun preparing and carrying out this event. Bila (Chemistry, 2nd year), making and tasting the Korean traditional candy dalgona, mentioned: “I expect people to engage in some more charity work through this flea market.” Mohd Khairil Rajaie Mohd Khairon (Electric Engineering, 3rd year) is posing infront of the dolls, some of which he donated. The market was crowded with students and passersby trying to purchase items at a good price. Because the organizers are composed of international students and domestic female students, all of the profit earned in the flea market will be donated to the Women Migrants Human Rights Center after the semester is over. The flea market raised 700,000won this year. Choi mentioned, “as I major in engineering, there is not much chance for me to organize events and host them. I think WE-HY supporter is a place where imaginations come true. I wish more students interested in such issues can participate in the supporters’ activity,” smiling.

[Academics][Excellent R&D] Inventing Eyes for Robots

Augmented Reality, self-driving cars, and facial recognition are no longer a technology of future. Such advanced technologies are deep in our daily lives. In order for machines to properly function as they are meant to, they need something called ‘machine vision’. Machine vision (MV) is the technology and method used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry. And the field that encompasses the subject is Computer Vision, which Lim majors. For December’s Researcher of the Month, News H interviewed Lim Jong-woo (Professor, Department of Computer Science) who recently won a major government project to acquire the source technology for such field. Lim is enthusiastically explaining how the technology can be applied in real lives. For example, with the structure modeling, calculating the altitude of a person's eye level (when wearing an AR/VR glasses) would be possble. The final goal of this four-year project is to develop a high-level video situation recognition technology based on structural modeling and geometrical analysis of images acquired in extremely congested situations such as the real environment. Structural modeling of a video means to draw lines and actually structure the surrounding environment within the video, either in a two-dimensional or three-dimensional form. Up to current technology, a system can process a single object in the video or occasionally multiple objects. However, it is not yet developed for computers to recognize and analyze a ‘congested’ video with dozens of moving objects, which is often the case in real life footage. “If developed further enough, a computer would be able to track irregular paths taken by a suspect from CCTV video and alert us,” mentioned Lim. (Left) Estimation of the structure of a space through existing technology (Right) Provisioned result of structure estimation (Photo courtesy of Lim) One of the ultimate goals of the project is to also integrate multi-object detection and tracking with the environment. “There are a lot of people trying to integrate detection and tracking technology,” said Lim. Because it is highly improbable for researchers to set a model human face for the computer to detect all human faces, integrating such technology with tracking a moving person is even more intricate and difficult. Nevertheless, if it does become reality, computers will be able to read the context of a specific video. For instance, because they can recognize each person, it would be able to write a storyline and understand relationships between characters in a show or a movie. As mentioned in the earlier part of the article, computer vision is a crucial part of augmented reality and autonomous cars. In the case of AR, the computer must be able to structure its environment to decide where to put the virtual object. Also, by such mapping, the machine can change its perspective in accordance with the user’s change of perspective. Furthermore, autonomous cars require even higher accuracy of computer vision in order to detect obstacles and prevent unwanted accidents. Unlike the facial detection of a camera app on our cellphone which is not really a matter of life and death, technology related to transportation has higher standards for that reason. "I aim to research for use, rather than a reasearch for research." Another surprising aspect of this research project plan is that the team will upload their findings on the web, free of charge as an open-source. When asked why not commercialize it, Lim answered “It is mutually beneficial for us to have the crowd test our algorithm and give feedback to us, as we cannot test it in every environment. Also, it is a trend to release algorithms open-source, because most of them fall short to be commercialized yet.” The research has begun this August and will be continued until the end of 2020. News H is looking forward to observing Lim’s progress and the social impact his team will bring. Kim So-yun Photos by Choi Min-ju

[Performance]Hanyang University Being the Stepping Stone for Start-up Companies

The term ‘crowdfunding’, which refers to the practice of funding a project or venture by raising a small amount of money from a large number of individuals, typically via the Internet, has become one of daily vocabularies. This year, Hanyang university’s Startup Support Foundation has collaborated with a global crowdfunding online platform to provide fund raising opportunities for growing ventures in Korea. The Indiegogo Pilot Program started on the 8th of August, and the duration is approximately four months, having the product launching in early November. Poster informing applications for the Indiegogo Pilot Program, details are written below. (Photo courtesy of Center for Business Incubation) “Indiegogo runs this program every quarter, and Hanyang applied this time,” said the manager in charge, Joe Jong-hyuk. Five companies chosen by HYU were provided with online crowdfunding coach programs made by Indiegogo. Then, their business items were analyzed thoroughly to decide which companies should be in the final list of support. Two promising companies survived this process: Zero Founders and Brilliant & Company. Portable fine dust measuring device, Brilliant & Company Founded in 2015, Brilliant & Company developed a portable fine dust measuring device that can be linked to mobile phones. The company successfully raised funds through Wadiz (a Korean crowdfunding online platform) and Kakao story funding in 2016. Based on such know-hows and technological experiences, the firm created a new device called ‘PiCO’. PiCO is a living environment monitor that detects not only fine dust but also temperature, humidity, and CO2 level around the user. PiCo from Brilliant & Company. It also has it's own mobile application that can be paired with cellphones. (Photo courtesy of Brilliant & Company) “We applied to this program thanks to the manager Joe,” mentioned Yoon Jung-yoon, CEO of Brilliant & Company. According to Yoon, Hanyang Startup Support Foundation provided a lot of support and help to the ventures occupying the building. For example, whenever the Brilliant & Company had issues on their prototype, the center would suggest solutions based on their abundant experiences, or even introduce consulting firms when it comes to financial issues. Yoon ambitiously said that they are aiming to raise a million dollars through Indiegogo pilot program. “You always have to aim high, don’t you?” chuckled Yoon. Nevertheless, capital is not the only thing a venture can acquire through this program. The business can also find global IT retail partners such as Home-Bau in Germany. Check how your skin is today with Zerofounders The other company which made it to the final Indiegogo support venture is Zerofounders. This global beauty technology company has two main products related to the pilot program. The first one is INCO which measures body fat from the user’s abdominal thickness. ECLAIR measures one’s skin condition, especially the balance of oil and moisture based on the user’s biological cycle such as sleep time and work out regularity. Zerofounders aims to make the betterment of women’s lives. Therefore, they research and develop devices that can help women manage their outer beauty whenever needed. Zerofounder's products, INCO (left) and ECLAIR (right). (Photo courtesy of Zerofounders) Jung Hannah, CEO of Zerofounders said, “crowdfunding is a platform where early adopters looking for innovative products are concentrated.” Jung was planning to promote their new ECLAIR through such a platform when she received an email from HYU. One of the many benefits of participating in the Indiegogo Pilot Program is that the venture companies can acquire deep insight in the whole process of crowdfunding, from making promotion videos to the actual launching of the product. Joe mentioned, “Hanyang Startup Support Foundation is supporting the financials of the video making and marketing for now, and we plan to provide more aid when needed.” With the help of Hanyang and Indiegogo, Zerofounders targets North American and European markets. Specifically, they aim to collaborate with cosmetic brands or to have offline stores. Startup Support Foundation operates and organizes numerous programs like this to support growing ventures and start-up businesses regardless of the CEO's school backgroud.

[Academics]Wastewater Treatment Facility to a Potential Power Plant

"Biomass is the only replacement for fossil fuels," said Jeon with certainty. Biomass is defined as living or recently dead organisms and any byproducts of those organisms, plant or animal. It can be used to produce renewable electricity, thermal energy, or transportation fuels (biofuels). In his recent review article, "Recent progress in microalgal biomass production coupled with wastewater treatment for biofuel generation," Jeon reviewed the technologies required to successfully integrate the two seemingly different areas: wastewater treatment and cultivation of microalgae. Jeon is enthusiastically explaining his recent article and progress of related fields. In order to generate biofuel, a substantial amount of biomass is required. Biomass is found in the natural world, such as in food crops. However, and often times, they are rare and have a low energy yield. Microalgae overcome all of the stated shortcomings. Known as one of the fastest growing life forms on earth, microalgae are found in fresh water or marine systems but can also survive versatile environmental conditions. In other words, microalgae have optimal conditions to be converted into energy. This potential energy source requires abundant Nitrogen and Phosphorus along with diverse minerals, and surprisingly enough, wastewater is a source of such nutrients. With the adequate pre-treatment of wastewater, a sewage disposal plant can turn into a ground for the mass cultivation of microalgae. This particular review article written by Jeon and his colleagues discourse on the advantages and disadvantages of recent progress and research around the world on such point. The reason why Jeon's research team can write such a review article concentrated on the relationship between microalgae and wastewater treatment is because the very research team discovered that wastewater can be used as a type of microalgae farm. "I personally dream to change such disposal plants into energy plants," said Jeon. He mentioned that 0.5% of the national electricity is spent on the wastewater treatment facilities. What if that facility can generate the amount of resource they use? Or even better, utilize the infrastructure to produce even more energy? "Sewage plant is located in every other neighborhood, unlike other power plants such as nuclear or coal plants. If sewage plants can create energy, the town will be a self-sufficient town." A chart explaining the relations among microalgae cultivation facilities, microalgal biomass and how water is purified while generating biofuels. (Photo courtesy of Jeon) In becoming one of the leading labs in the field, Jeon emphasizes looking through the keywords. As a college student, Jeon believed that ‘environment' and ‘energy' are going to be one of the most conversed topics in the future. Environmental engineering and eco-friendly energy came naturally into his pathway, which led Jeon to where he is now. Mentioning the fact that Korea can produce only ca. 0.3% of biogas than that of Germany's, Jeon suggested that the environmental engineering field in Korea still needs further research and development. "The field is very future-oriented," said Jeon. "Among the many topics that are and going to be significant in the coming days, renewable and environmentally friendly energy are some of the areas that engineers can contribute to." Jeon plans to keep working on his dream to convert wastewater facilities into energy-independent, and energy-creating social infrastructure. Jeon is holding a cylinder with microalgae in his lab.

[Event]Delivering Dynamic Spirits Through Their Breaths

With a strong sound of the timpani, the 2017 Hanyang Wind Orchestra raised its curtain on Sunday, September 17. Wind Orchestra is named after the characteristics of the instruments used in the performance. Wind instruments such as the flute, oboe and clarinet fill most of the stage with percussion and some string instruments. “Wind Orchestra can fulfill both artistic and public needs in music as percussion and wind instruments create dynamic sounds.” Said Park Min-ji, from the Department of String & Wind Intsruments. Members of the Wind Orchestra, collaborator Lim Jae-woong (Department of String & Wind Intsruments, 4th year) and conductor Kim Eung-du (Adjunct professor, Department of String & Wind Intsruments) are on stage for the rehearsal. Pieces with diverse emotions Dynamica written by Jan Van der Roost was the first song to welcome the audience with a bright and powerful mood. The piece instantly filled the KBS hall in Yeouido with joy and glee, making the audience anticipate the next number. The song then turned into another phase where it instantly changed the whole atmosphere. Minor codes running off fast imposed a nervous feeling, as if the orchestra was being chased by something. Concertino da camera introduced one of the stars of the night, Lim Jae-woong (Department of String & Wind Intsruments, 4th year). Lim played fast and complicated notes with a saxophone and made it look so easy, almost without a blink. As the main collaborator, Lim competed against more than 10 students for the spotlight. “It sounded like an OST from a TV soap opera. The grand music was almost overwhelming” said Lee ye-rim (10), daughter of an anonymous graduate from the Department of Urban Planning. “We came to see one of our old friends, and decided to take our kids for educational purposes.” The Lee family is taking a photo at KBS hall during the intermission. Lee Ye-rim (10) in the top middle and the anonymous alumni, far right. The following piece, Angels in the Architecture presents a somewhat unfamiliar instrument called ‘whirlies’. This instrument creates a beautiful wind sound that falls perfectly with the soprano’s voice (featuring as ‘angel’) and the title of the song. The composer Frank Ticheli noted that the whirlies are supposed to represent the halo of the angel, too. Irmak Akoglu, an exchange student majoring in biomedical engineering revealed that this is her first time at an orchestral performance, and said, “the songs they chose were amazing. It gave me so many different emotions." University of Texas Wind Ensemble is performing Angels in the Architecture with the composer and conductor, Frank Ticheli. The white ribbon-like instruments being waved around are the whirlies. (Photo courtesy of The University of Texas Band) An interactive performance After the 15 minute intermission, four songs were given: Lento, Scherzo, Mesto and Allegro Giocoso as part of the Third Symphony. Then, loud applause broke out for a long time, long enough for the conductor Kim to introduce every member of the orchestra. "Encore!” “Bravo!” as several audience members shouted out their excitement. Part of the brochure of the 2017 Hanyang Wind Orchestra. (Photo courtesy of College of Music) Two encore songs followed, including Hanyang’s official school song. The first one was absolutely the most impressive encore of all time. Conductor Kim held a microphone and showed gratitude for all the people who came to see the performance, and he excitedly went on to say, “I want to take you all to an amusement park. If I give you a sign, please scream for 30 seconds as you are riding a rollercoaster. Please do scream out loud as much as the lights can fall out from the ceiling!” The performers moved their body back and forth while playing the instruments to truly bring out the mood for the audience and when Kim signed, they raised their arms and screamed enthusiastically. Along with ovation that again lasted for a long time, this year’s Hanyang Wind Orchestra closed its curtain. "All seats of the performance are free of charge and based on invitation every year to enlarge the opportunities for Hanyang students and faculty members so that they can be exposed in this unique form of orchestra,” said Park. If you have missed this year’s show, there still is a chance soon on November 2, as the orchestra was invited to a college orchestra festival. Kim So-yun Photos by Park Young-min

[Academics][Researcher of the Month] What Makes People Pro-Environment? (1)

“Whenever I go on a trip or big festivals, I always worry about all the trashes people throw away. It’s just too much.” Professor Hyun Sung-hyup of the Division of Tourism recently published his paper, "Fostering customers’ pro-environmental behavior at museum". The paper thoroughly investigates the affective and cognitive factors of individuals visiting museums and analyzes which factor has the most impact on their pro-environmental intentions. Hyun emphasized that most people are very environmentally friendly in their house. They recycle well, try not to waste food or water. However, the point is that the very same people behave entirely differently from the moment they leave their house. Trashes are disposed not separately, which then has to be combusted, letting carbon into the air. Tissues, water, food and all kinds of resources are wasted. Hyun wondered what is behind the people’s paradoxical behavior. He also wanted to figure out what needs to be triggered in order to resolve such paradox and to motivate eco-friendly behavior from the general public. A table showing relations of each factor and their effects (Photo courtesy of Hyun) Over the course of a year, Hyun went to a broad range of museums which deal with themes like art, war, and tradition to interview, survey and observe the visitors. From the data collected from 321 tourists, he ran statistical analysis simulation program to construct a conceptual framework that can predict people’s behavior in public spaces. He also sought for professional advice from other fields such as environmental specialists or professors in engineering for further insight. Based on his field research with dozens and hundreds of related papers he studied, Hyun found out that ‘Environmental Knowledge (EK)’ out of five cognitive factors, was the most significant factor in determining one’s environmentally responsible decision-making process. Hyun is explaining the process of his research. Hyun asserted that environmental education on a regular basis is essential. People with more professional knowledge on the vulnerability of the environment or the impact of their action is more inclined to show consistent behavior both in and outside of their home. "It seems like a lot of people lack education regarding the environment in both public and private sectors," said Hyun. Lamenting at such reality, Hyun wishes environmental education to be part of the public education curriculum in the near future. When asked what inspired him to become a researcher in Tourism, Hyun smiled and answered that his professors during college years influenced him a lot. “Hanyang University offers the best curriculum on Tourism, with respectful professors. I always looked up to them.” Hyun said he decided to study further because there are so much intriguing topics to research in the field of Tourism. He encourages future researchers in the field to boldly try out, because tourism is very future oriented, interdisciplinary and economically significant field of study. Hyun himself plans to vigorously research further on issues related with environment and tourism. “Researching while lecturing, mentoring and living personal life is tough but I still enjoy it,” said Hyun, with affection to his work.

[Academics]Beyond the Matter of Life and Death

Most people do not enjoy postoperative scars, especially on the visible parts of their body. Professor Tae Kyung of Department of Medicine recently reported the outcomes of newly developed operation method in his paper “Functional and cosmetic outcomes of robot-assisted neck dissection by a postauricular facelift approach for head and neck cancer”. As from the title Tae’s research compared surgical outcomes of both conventional neck dissection and his new facelift approach, which takes cosmetic aspects of the patients into account. “Nowadays, it is more than just life and death. Quality of life after the operation is also important.” (Photo courtesy of Tae) In the case of patients with head and neck cancer, cancer cell often spreads to the lymph node of cervical (neck) area. The conventional surgical method to treat the lymph node metastasis is to give vertical and transverse cervical incision (cut), which leaves permanent mark in the patient’s neck. As always having interest in plastic surgery – which is part of Otolaryngology (Head and Neck Surgery) – Tae concerned for postoperative quality of life. Therefore, he took the facelift approach which is still mostly used for cosmetic purposes, especially to unwrinkle one’s face. This way, the scar is left in the back side of the patient’s ear alongside the hairline, which is significantly less visible. The paper “Functional and cosmetic outcomes of robot-assisted neck dissection by a postauricular facelift approach for head and neck cancer” specifically reports the postoperative outcomes of the revolutionary implication as short as one day after the surgery to as long as 12 months. From 2013 Tae and his co-researchers collected data of 113 patients who underwent unilateral neck dissection both through the particular approach and the conventional approach. As a result, the team led by Tae was able to compare the functional and cosmetic outcomes which proved that Tae’s method is advantageous. Namely, patients suffered from less neck edema (swelling of neck) and sensory loss. Cosmetically patients reported significantly lower satisfaction scores. (Note that the higher the satisfaction is, the lower the scores are.) Both neck edema and sensory loss is lower in the robotic procedure, as shown in the tables. (Photo courtesy of Tae) Another specialty of Tae’s method of operation is that it requires robotic assist called Da Vinci robot because the operation makes a very thin tunnel inside the neck, making it physically impossible for the surgeons otherwise. Tae, as one of the first person in the world to conduct robotic neck dissection wanted to further develop the method and evaluate it. This report is one of his efforts trying to keep evaluating and improving his new surgical method. “It is still early to report the cure rate of cancer through this method, but now we know about the postoperative sensory loss, motion limitations, and the satisfaction of patients through this research,” said Tae. Tae also struggles to improve Otolaryngology in Korea and Asia. He mentioned that he chose to become head and neck surgeon because the area was less developed and researched at that time, and that challenged him. Now he is a general secretary of Asia Pacific Society of Thyroid Surgery which he founded, wishing well for the future of the field. “I wish my students to improve Korea as much to be the leading country in Otolaryngology and become global leaders.” Kim So-yun Photos by Choi Min-ju
