[Academics][Researcher of the Month] How ‘Fit' Are You With Your Boss? (1)

For a higher competency of a company or a corporation, factors like personality, values and goals that employees and leaders prioritize were focus of a research in management or psychology studies. It has been thought that such factors should be met between a leader and an employee for higher effectiveness in a company. Rather than determining how ‘fit’ a leader and an employee is under the standards of aforementioned aspects, there has been a new perspective suggested by Professor Shin Yu-hyung of the Department of Management. Appointed as one of the researchers of the month, her recent paper, “Does Leader-Follower Regulatory Fit Matter? The Role of Regulatory Fit in Followers’ Organizational Citizenship Behavior” discusses the two different concepts, ‘promotion focus’ and ‘prevention focus’ and how it works between a leader and an employee. From her doctoral course, Shin realized how aptitude and characterisitcs of people are important. The core of Shin’s research is one’s different strategic intentions, which can be divided into prevention focus and promotion focus. Promotion focus refers to a strategy to bear risks for positive outcome. Thus employees with promotion focus would put themselves into challenges for better results in their tasks even if they have to bear risks during the process. On the other hand, employees with prevention focus will contain themselves inside a security zone, putting their biggest effort to avoid the worst outcome. Thus, unlike the ones with promotion focus, they would not try to change the conditions in the given environment and will aim to accomplish the goals within the boundary of rules or conditions. For example, consider two college students in their 3rd year. Both of them studies hard to get better GPAs but their focus can be different. Student A with promotion focus studies hard because A wants to get higher scores to apply to a company he or she wishes. Student B with prevention focus would only study hard merely to avoid an F on his or her GPA. In the paper, Shin tried to examine and demonstrate such relevance with Organizational Citizenship Behavior (OCB), which refers to discretionary and extra-role behavior that is considered to increase overall effectiveness in an organization, a company in this case. What Shin chose was to prove it through a survey. She chose 140 leaders and 640 employees from different fields of Korean domestic companies. The questions mainly asked of one’s attitude to different focus, whether it is more toward promotion or prevention. As a result, Shin was able to witness different focus strategy each employees and their leaders take. According to the graph, the allignment of leader and follower (employee) proves the highest effectiveness of OCB. (Photo courtesy of Shin) Analysis of the survey showed several facts. First, when an employee pursues promotion focus, his or her fit with a leader showed less significance. “People with high promotion focus are the ones who tries to break a conventional frame or a box, which makes their fit with their leaders less necessary. Only their degree of the focus will determine their degree of accomplishment,” explained Shin. However, the importance of ‘fit’ was shown in the case of an employee with high prevention focus. In this case it has been proven that the more one is fit with his or her leader, the better accomplishment one can make. “As people with prevention focus tries to work most effectively within the given frame, they try to cooperate and negotiate well with others while abiding by the law, which makes the fit with their leaders more important,” said Shin. While researches on regulatory fit between leaders and employees have been done for a long time, the different perspective Shin suggested is getting credits for positive feedbacks of the paper. In the same line, Shin is working on how various styles of working can affect the outcome. In a case like where an employee is the one who tends to take more steps in completing his task while his or her leader is the one who is always chased by the dead line. As the cooperation between a leader and an employee is always important for a successful company, Shin expects the research could positively affect and motivate more innovative management studies. Shin said she will keep on researching to contribute to HYU and Korea's good brand image. Yun Ji-hyun uni27@hanyang.ac.kr Photos by Kim Youn-soo

[Academics][Researcher of the Month] Detecting Ultra-Sensitive Benzene

Professor Kim Hyoun-woo of the Division of Materials Science and Engineering is April’s Researcher of the Month, for his active role in exploring the field of materials science and engineering. In his paper “Ultra-sensitive benzene detection by a novel approach: Core-shell nanowires combined with the Pd-functionalization”, Kim explains how the detection of benzene gas has become much more efficient than ever. The palladium being extra sensitive to benzene gas has been the key to the detection technique which has drawn attention in this field. Kim has discovered the link between palladium and benzene gas. The Pd-functionalized SnO2-ZnO C-S NW is the substance developed by Kim in order to detect benzene, a toxic gas. Since nano-sized palladium particles are added on a cell with SnO2 and ZnO covered on top, the sensor produces a spillover effect, distributing the benzene gas particles along the conduction band. The effectiveness of Kim's model is proven through the gas response. (Photo courtesy of Kim) This is important since benzene gas can be found in everyday life. It is inside cigarette smoke, smog, exhaust fumes and may be found in new houses, creating sick house syndrome. Through Kim’s finding, this benzene gas, which could be lethal to human lives, can be spotted in a much more sensitive manner. Since the sensors and cells created in a smaller size would lead to higher sensitivity, the particles have been selected in nano-sizes. The only problem that could arise with this sensor is that it depends heavily upon the selectivity of which gas it wants to detect. The compatibility between different particles could create great results as Kim has found out in the case of palladium and benzene, while in other cases, disastrous results may be spawned. Kim explains how his model works. Kim wishes to develop better usage of sensors than those that are being distributed in every day life as of now. “I want to find the best usage of a new sensing principle totally different from the current ones,” said Kim.

[Student]Experiences at Hanyang, Francesca's story

Francesca Barbieri, the student from Humanitas University, the private university at Italy dedicated to the medical sciences, participated Hanyang summer program for her medical training. She shared her remarkable experiences and memories here at Hanyang University. Prescription For Growing: Learn Skills But Especially Make Friends I would have never imagined to realize such a big project in such a short time. I found myself on the other side of the world just after a few months I started thinking about it. As I knew about the possibility of obtaining a travel grant, I applied and was then accepted by the cardiology Professor Kyung -Soo KIM. Humanitas therefore gave me the opportunity to spend more than 40 days at the Hanyang University Medical Centre, in Seoul. There, I attended the cardiology wards, outpatient visits and the cardiology research laboratory. To tell the truth, the difficulties of such an experience can be many and discouraging. But everything becomes so pleasant and worthy when you meet the right group of people. Professor Kim and his group of physicians, residents, laboratory members and students accepted me as if I had always been one of them. My family and friends were definitely far away, but I found myself in an environment in which I never felt alone, I could ask anything I needed and was given all the possible help. Trying to follow them during the working day was though, with no doubt. I used to spend between 12 and 13 hours per day in the hospital, some in the clinic, some in the laboratories. As a second year student, I felt to have a solid theoretical knowledge but it was the first time for me to approach the practical clinical environment or research designs and laboratory protocols. I arrived as a very worried student, concerned about what to expect. I came out after 40 days with a basic knowledge of the main heart diseases, how to use the laboratory equipment, how to follow an experimental research design. This was achieved thanks to the constant, careful and personal tutoring I was provided, I always had at least one physician or one researcher on my side. I came out as part of a group of friends, and this was the most surprising and precious aspect. The attention they paid to the success and profit of my experience was invaluable. As invaluable is what I have learnt. Sometimes it is unbelievable how much we can grow in such a short time. * Original article at Hunimed.edu (link)

[Academics][Researcher of the Month] Blue Ocean of Materials Science

Conspicuous or not, our surroundings play a crucial role in navigating our health, holding accountability for small and big degenerations for mankind’s physical wellbeing. Among all, two indispensable elements in our life, air and water, have slow and accumulative effect on the health of the population. Professor Kim Ki-hyun (Department of Civil and Environmental Engineering), whose studies focus on environmental pollution, delineated the means of applying advanced materials in his review paper “Carbon nanotubes: a novel material for multifaceted applications in human healthcare.” Carbon nanotubes in biotechnology As modern material technology has been advancing considerably, its application seems ever-expanding in diverse fields, with nanomaterials as the convenient and indispensable companion. Based on a research paper conducted by other scholars, Kim wrote another, centralizing on the uses of carbon nanotubes (CNT), an emerging nanomaterial that is seeing the light in the biomedical and environmental fields. Its application is versatile: drug delivery, sensing, water purification, composite materials, and bone scaffolds. More specifically, CNTs could be used to alleviate myocardial infarction by enlarging clogged blood vessels, expediting drug delivery, and organizing bone structures in needed parts. Kim outlines his review paper on the application of carbon nanotubes in the biomedical field. Despite all the medical benefits, advanced materials including CNT also have the potential to bring adverse effects. As alien substances could disturb immune or antibody responses, the body functions to react against them. Especially, in case of new materials, unprecedented resistance could occur, and thus their potential impacts must be taken into consideration through attentive examination for possible toxicity. Nonetheless, as long as the criteria are met, CNT and other materials could spark revolutionary breakthroughs that would change the future of mankind. “I think that endless developments are yet to come in the field of materials science to help other research fields like environment and human health flourish. Better materials in terms of cost efficiency and functional effectiveness would be improved while there is yet no limits to such developments. Materials science and nanomaterials would not only be fruitful in biomedical fields but also environmentally,” commented Kim. His interest in new materials are extended toward environmental progress, starting with the sensing of pollutants and purifying polluted medium. The blue ocean Materials science could often be referred to as the 'blue ocean' since there are more to be discovered than what has been excavated so far. On top of this, collaboration with environmental issues is not conventional. Kim is involved in research for integrated environmental monitoring technology, digitizing and managing air, water, and soil pollution. He is looking forward to fuse newly unveiled materials in his research, hoping to bring a constructive result to lay a bridge between materials science and environmental engineering. To set an example, metal-organic frameworks (MOFs) could be used to mitigate environment pollution: volatile organic compounds (VOC) in the air spawns odor while propagating carcinogens if transferred into the human body through the respiratory system. As the material for sensing or removing such hazardous pollutants, MOFs are regarded as one of the highly promising solutions. What is to be underscored here is the infinite possibility of combination of the materials, which are not only capable of being used alone but also of being employed in cooperation with other materials. Kim's research will continue to be centered around mitigating environmental pollution with newly excavated materials. Jeon Chae-yun chaeyun111@hanyang.ac.kr Photos by Choi Min-ju

[Academics][Researcher of the Month] Al-FCG Ready for Action

Professor Sun Yang-guk of the Department of Energy Engineering is February’s Researcher of the Month for his active role in exploring the field of energy engineering. In his paper, “Compositionally Graded Cathode Material with Long-Term Cycling Stability for Electric Vehicles Application”, Sun explains how adding aluminum into the cathode makes batteries last longer and become more stable compared to other rates of composition. The Al-FCG61 that Sun has developed has shown a high rate of energy efficiency even at 100% depth of discharge (DOD), which draws attention in the field. Sun explains his research with assisted diagrams. As the supply and demand of the electric vehicle is on the rise, most of the batteries in the market last from 150km to 400km, meaning that once the battery is fully charged, the car would move between the distance within. What accounts for the difference is the capacity as to how much cathode can hold up. In order for cars to go beyond 300km at least, the capacity of the cathode would have to be over 200A/h. The only problem to this is that it gets difficult to make it stable and it could blow up. There are various prototypes ranging from generation 1 to generation 4 and the study carried out in Sun's paper is on generation 3. Gradients of different components from inner to outer parts of nickel particle. (Photo courtesy of Sun) Capacity retention, which is the lifespan of a battery, would rise with 61% of nickel with FCG full concentration gradient, which is what Sun has developed in order to create a more stable and long-lasting battery that would hold a larger capacity. Within the mold, Sun has created a two-way particle that contains a high percentage of nickel inside with lower percentage of nickel on the outside. This concentration gradient is created due to the fact that nickel has its advantage of being able to increase the capacity of the battery while it makes the battery more unstable with exothermic reaction. Along with the nickel, Sun has increased the percentage of the manganese inside the particle since it has the advantage of making the cathode more stable. Depth of discharge (DOD) is the rate at which battery is either charged 60% or 100%, and this is tested before electric vehicles are sold for inspection. The average usage of an electric vehicle is at around 2,500 cycles for 10 years, and the Al-FCG has proven to be more energy efficient even at 100%. Most of the batteries do not last long at DOD100 due to the expansion of volume inside the battery. This means that the battery would lose its efficiency as time goes. Al-FCG has shown its Coulombic efficiency rate of 84.5% even at DOD100, while batteries currently in the market show an average of 50% at 2000 cycles. This new battery devised by Sun is not only more energy efficient, but more cost efficient as well. Sun wishes to make more efficient batteries. Sun is continuously researching to keep the DOD level at 100% even after 2000 cycles. With his findings, the electric vehicle industry would definitely benefit hugely in terms of cost and energy efficiency. With different materials, Sun wishes to develop other types of batteries that would bring more comfort to society. Kim Seung-jun nzdave94@hanyang.ac.kr Photos by Kim Youn-soo

[Student]Hanbok Beloved Worldwide

From 4th of January to 9th of January, hanbok making class was held in Human Ecology Building by Won Young. She has studied about hanbok and designing at Hanyang University (HYU) while attending Department of Clothing and Textile. The classes were held two hours everyday excluding the weekends, for four times. How it all started Won Young is Malaysian Chinese and also a Korean gyopo. While she was living in China, she says that there used to be a lot of tribes wearing different types of traditional clothes which is when she first encountered hanbok. “I have seen hanbok a lot on the television but once I came to Korea, I couldn’t see anyone wearing it in real life,” Won said. In order to make up for the discomfort of the hanbok, she started studying about life hanbok and became interested in the designs. Won (right) teaches Helene (left) how to use the sewing machine. She has created a startup team called TS (Time and Space) which consists of two people at the moment. Since she has studied in the field of fashion, Won thought of creating a brand of her own or creating a platform. Although there used to be websites where flower printings were available, it seemed to be a waste to cut out the pieces while designing her own patterns. This is how Won came up with the idea of DIY fabric in which she designs her own patterns and inserts the prints within the patterns. While attending at HYU, Won has participated in diverse programs created for international students but she felt that something was missing. “It seems like I was just looking around rather than doing something at the complete experiencing level. I think there are a lot of foreigners who would think like me,” said Won. This is how she came up with the idea of hanbok making class. Reactions towards the program A total number of fourteen students from diverse countries have participated in this program. Cho Yu-jin (faculty at Department of Clothing and Textile) and Lee Ye-jin (acquaintance of Won) have helped out with this event. Cho has helped out with the over lock while Lee has helped with the translation with the foreign students. Since the students participating in this program did not have any experiences or were not related major to fashion or designing, they had a hard time putting this together and one of them had to do all the sewing all over again from the sketch. Renu (left) and Azira (right) enjoys the program. Most of the students who have participated in the program had a similar idea in a sense that they were not aware of hanbok and how it could be utilized in daily life as well. Hwang An-ki (Media Communication, 2nd yr) said, “I was not well aware of Hanbok in the first place but as I was making it, it came to me as a beautiful traditional clothing.” Since foreign students who do not return to their home countries have not much to experience, they all claim that it has been a great experience for them. “I think it’s quite interesting that some people still wear traditional clothes since we don’t have them in Denmark. I think hanbok is very beautiful costume,” claimed Helene (Korean Studies, Master’s program). Although it has been a short period of time, all the students were able to finish their hanboks. After the session has finished, participants have matched their casual clothes along with hanbok and had photo session afterwards. “Through making the hanbok, foreign students would have been able to have the sense of achievement and feel the traditional culture of Korean costume. Also, by being able to have felt a new type of experience of making clothes, some people would have found a new hobby as well,” added Won. The students who have participated will keep in contact with each other and exchange information on hanbok flea markets or Korean culture experiences. Through this program, foreign students now understand Korean culture a little more. Since it has been a greatly developed program where it has been a talent donation of Won, students from diverse countries were able to experience the beauty of hanbok. Won hopes that she could carry out more programs related to hanbok in the future as well and provide lessons as part of the Korean wave towards foreigners.

[Academics][Researcher of the Month] Scientific Integration Approach to Programmable Nuclease (1)

When a baby is identified to have been born with a rare, incurable disease, it would bring about concerns and sorrow to the newborn and the parents. However, with the prospective research on CRISPR Cas-9 system, or a programmable nuclease, a host of diseases will prevented without further ado. Professor Bae Sang-su of the Department of Chemistry explains the mechanism of the CRISPR Cas-9 system through his research “Structural roles of guide RNAs in the nuclease activity of Cas-9 endonuclease”. Also, he reveals the course of his life towards scientific integration that shapes the bright future of scientific studies. Structural properties and significance of CRISPR Cas-9 The significance of this research paper is that it explains the structural mechanisms of the CRISPR Cas-9 system and how it can modify or edit DNAs in cells. CRISPR-Cas 9 stands for Clustered Regularly Interspaced Short Palindromic Repeats, which relies on a protein named Cas-9. As it is called by the name of 'molecule scissors', it introduces the new spectrum of genome editing technology. Even though there already have been two programmable nuclease systems which are the Zinc Finger Nuclease and the TALENs(Transcriptor Activator Like Effector Nuclease System). The former is the first generation of the genome editing system that is compiled of one zinc finger and three to four nucleases. The title originated from the chemical component zinc, because this DNA contained certain amount of zinc. Then the second generation of genome editing system developed, which was called the TALENs that contained the base named xanthomonas originating from vegetable pathogens. “These two generations were startling contributions to scientific development, but with the advent of the third generation of genome editing, the CRISPR Cas-9 system, the scientific world could not contain its surprise,” said Bae. The CRISPR Cas-9 system was simpler in application to various circumstances and in the modification of DNAs. The significance of the CRISPR Cas-9 system is that it can enhance the welfare of human life in various aspects. “This technology is currently being applied to plants and animals, and also is in process of availing itself to humans by amending laws. Application of the system to humans will take 10 years at the most, since the research is developing at a fast pace,” explained Bae. An example of genome-modified plant through the CRISPR Cas-9 system that Bae provided was a modified mushroom in the United States. Discoloration of mushrooms by time lapse was prevented due to the CRISPR Cas-9 system, and the mushroom could maintain its original color for a long time. Bae explained that “not only does the CRISPR Cas-9 system treat incurable diseases of humans, but it can also modify DNAs in plants and animals to increase marketability.” Bae is explaining the significance of the CRISPR Cas-9 system. However, the genome editing system has been controversial in the scientific academia due to its resemblance to genetically modified organisms, also called GMO. According to Bae, there is a blunt difference between the two because GMO requires DNAs extracted from other organisms to modify the sample, while the CRISPR Cas-9 system modifies DNAs in the sample itself. “Even though some experts call the CRISPR Cas-9 system a part of GMO, the American Food and Drug Administration has acknowledged the genome editing program as a discrete system,” said Bae. Another controversy that the CRISPR Cas-9 system is incurring is the occurrence risk of a tailored baby. Even though there is a low possibility in creation of so called 'monsters', the prospect of the system is inexhaustible that the scientific academia can’t forecast the future application of the CRISPR Cas-9 system. “The application of the system should be discreetly considered and contemplated, in order to prevent any accounts of abuse incurred by a little crack of regulations,” said Bae. Scientific integration approach and its synergy effects One of the reasons why Bae could successfully reveal the mechanism of this newly found technology was due to his academic background. Bae got his bachelor’s, master’s, and doctoral degrees in physics, while pursuing chemical studies in his post-doctoral program. Once he became a professor in the chemistry department, he encountered the Method of the Year- 2013 published by Nature Method, which was introducing the new technology, the CRISPR Cas-9 system. As Bae was carried away by the astonishment, he got involved in the genome engineering research in earnest. “Although there could be some drawbacks for me to research biological technology because I majored in physics and chemistry, I thought that I can sublimate these flaws into advantages through scientific integration,” said Bae. Because he majored in physics, he could access the research in a physician’s perspective of ‘how and why’, instead of a biologist’s perspective of ‘so.’ According to Bae, he demonstrated his full potential and capabilities in this research as both physician and chemist, because he could inquire the structural mechanisms of the system and create programs using various physical means like razors. In his teenage years, Bae was interested in studying science since he was a student of natural sciences and engineering. Moment by moment, Bae immersed himself in scientific research, and in his graduate school years, he spent great energy and time researching for scientific development. Due to his diverse academic background, Bae could successfully pursue his amalgamative research in different scientific fields. Now, another approach to scientific integration is in progress, as the CRISPR Cas-9 system is being applied to different fields. “As a scientist researching the CRISPR Cas-9 system, I have to cooperate with experts from profoundly dissimilar fields. Lack of knowledge between each others’ academic branches and hardship in communication may bring about discord. Thus, efforts to understand and study each others’ academic knowledge through cooperation is the key to successful results,” said Bae. A scientific integration approach has been the key to successful research on the CRISPR Cas-9 system. Bae's ultimate goal is to apply this original research of CRISPR Cas-9 system to different fields through joint research. To the question of how he will encourage and foster junior scholars at Hanyang University, he answered with ‘confidence.’ “I have studied and researched at various universities with different experts, and I have realized that students of Hanyang University are equally capable to these scientists. With confidence and courage to carry on their majors with tenacity, students of Hanyang University can demonstrate their capabilities to the fullest,” said Bae.
