Activation of Bystander Immune Cells during Acute Hepatitis A.
A KAIST research team has identified a process of tissue damage caused by bystander immune cells in acute viral infections. This research will pave the way for research to understand the principles of tissue damage in viral infections and immune diseases, and can point toward a possible therapeutic target for the treatment.
Upon viral infection, viral replication itself destroys human cells, but in some cases, viral replication is not the direct cause of the tissue damage. In particular, the destruction of infected cells is the primary cause of tissue damage during non-cytopathic viral infections such as hepatitis A virus, hepatitis B virus and hepatitis C virus. However, the underlying pathological mechanisms involved in the tissue damage during viral infections have not been fully elucidated.
Specificity is one of the most important characteristics of the immune system. In general, infection from a certain virus specifically activates immune cells targeting the virus, while other immune cells specific to different viruses remain inactive.
An immune cell not specific to an infected virus is called a bystander immune cell. A phenomenon that activates irrelevant immune cells not originally targeting the infecting virus, called the activation of bystander immune cells, is already known to the world; however, its clinical significance has not been investigated thoroughly.
Professor Eui-Cheol Shin and Professor Su-Hyung Park from the Graduate School of Medical Science and Engineering analyzed patients with acute hepatitis A, in collaboration with Chung-Ang University Hospital.
The team found not only immune cells specifically targeting the hepatitis A virus were activated, but also bystander immune cells were activated and involved in the damaging of liver tissues during acute hepatitis A.
According to the research, when a person is infected with hepatitis A virus, hepatitis A virus-infected cells produce IL-15, which induces the activation of bystander immune cells. Activated bystander immune cells exert innate-like cytotoxicity, triggered by activating receptors NKG2D and NKp30 and this can lead to liver injury.
Through describing the cause of excessive tissue damage during acute viral hepatitis, the research outcome is expected to provide critical contributions for the development of potential therapeutic intervention that can minimize tissue damage caused by viral hepatitis and immune disorders.
Professor Shin said, “This is a novel research case that discovered the clinical significance of bystander immune cell activation, which was previously unknown. We will continue to work on establishing treatments which could prevent tissue damage in viral and immune diseases in the future.”
This research was published in Immunity on January 2.

KAIST Finds the Principle of Electric Wind in Plasma
(From left: Professor Wonho Choe and PhD Sanghoo Park)
A KAIST team identified the basic principle of electric wind in plasma. This finding will contribute to developing technology in various applications of plasma, including fluid control technology.
Professor Wonho Choe from the Department of Physics and his team identified the main principle of neutral gas flow in plasma, known as ‘electric wind’, in collaboration with Professor Se Youn Moon’s team at Chonbuk National University.
Electric wind in plasma is a well-known consequence of interactions arising from collisions between charged particles (electrons or ions) and neutral particles. It refers to the flow of neutral gas that occurs when charged particles accelerate and collide with a neutral gas.
This is a way to create air movement without mechanical movement, such as fan wings, and it is gaining interest as a next-generation technology to replace existing fans. However, there was no experimental evidence of the cause.
To identify the cause, the team used atmospheric pressure plasma. As a result, the team succeeded in identifying streamer propagation and space charge drift from electrohydrodynamic (EHD) force in a qualitative manner.
According to the team, streamer propagation has very little effect on electric wind, but space charge drift that follows streamer propagation and collapse was the main cause of electric wind.
The team also identified that electrons, instead of negatively charged ions, were key components of electric wind generation in certain plasmas.
Furthermore, electric wind with the highest speed of 4 m/s was created in a helium jet plasma, which is one fourth the speed of a typhoon. These results indicate that the study could provide basic principles to effectively control the speed of electric wind.
Professor Choe said, “These findings set a significant foundation to understand the interactions between electrons or ions and neutral particles that occur in weakly ionized plasmas, such as atmospheric pressure plasmas. This can play an important role in expanding the field of fluid-control applications using plasmas which becomes economically and commercially interest.”
This research, led by PhD Sanghoo Park, was published online in Nature Communications on January 25.

Successful Synthesis of Gamma-Lanctam Rings from Hydrocarbons
(The team of Professor Chang, far right, at the Department of Chemistry)
KAIST chemists have designed a novel strategy to synthesize ring-shaped cyclic molecules, highly sought-after by pharmaceutical and chemical industries, and known as gamma-lactams. This study describes how these five-membered rings can be prepared from inexpensive and readily available feedstock hydrocarbons, as well as from complex organic molecules, such as amino acids and steroids.
Gamma-lactams find several applications in medicinal, synthetic, and material chemistry. For example, they are included in a large number of pharmaceutically active compounds with antibiotic, anti-inflammatory, and anti-tumoral functions. This research was published in Science on March 2.
Conversion of hydrocarbons into nitrogen-containing compounds is an important area of research, where the challenge lies in breaking strong carbon-hydrogen (C−H) bonds, and converting them into carbon-nitrogen (C–N) bonds in a controlled fashion. For this reason, hydrocarbons are difficult to use as starting materials, albeit the fact that they exist in large quantities in nature.
Over the last 35 years, chemists have found ways of converting simple hydrocarbons into nitrogen-containing rings, such as indoles or pyrrolidines, but gamma-lactams proved impossible to prepare using the same approaches. Researchers hypothesized that such failure was due to alternative chemical pathways that steer the reaction away from the wanted rings: The reaction intermediate (carbonylnitrene) quickly breaks down into unsought products. Using computer models of the desired and undesired reaction pathways, the team found a strategy to completely shut down the latter in order to obtain the longed-for gamma-lactams. For the first time, these four carbons and one nitrogen cyclic molecules were obtained directly from simple feedstock chemicals.
Led by Professor Chang Sukbok at the Department of Chemistry, the team designed the winning reaction with the help of computer simulations that analyze the reaction mechanisms and calculate the energy required for the reaction to take place. According to such computer predictions, the reaction could follow three pathways, leading to the formation of either the desired gamma-lactam, an unwanted product (isocyanate), or the degradation of the catalyst caused by the substrate reacting with the catalyst backbone. Combining experimental observations and detailed computer simulations, the team designed an iridium-based catalyst, highly selective for the gamma-lactam formation. In this way, the two undesired pathways were systematically shut down, leaving the formation of the nitrogen-containing ring as the only possible outcome. Professor Chang is also in charge of the Center for Catalytic Hydrocarbon Functionalizations at the Institute for Basic Science (IBS).
“With this work we offer a brand new solution to a long-standing challenge and demonstrate the power of what we call mechanism-based reaction development,” explains Professor Baik Mu-Hyun, a corresponding author of the study.
Beyond using cheap feedstock hydrocarbons as substrates, the team was also successful in converting amino acids, steroids, and other bio-relevant molecules into gamma-lactams, which might find a variety of applications as plant insecticide, drugs against parasitic worms, or anti-aging agents. This new synthetic technology gives much easier access to these complicated molecules and will enable the development of potential drugs in a much shorter amount of time at a lower cost.

Aqueous Storage Device Needs Only 20 Seconds to Go
(from left: PhD candidate Il Woo Ock and Professor Jeung Ku Kang)
A KAIST research team developed a new hybrid energy storage device that can be charged in less than half a minute. It employs aqueous electrolytes instead of flammable organic solvents, so it is both environmentally friendly and safe. It also facilitates a boosting charge with high energy density, which makes it suitable for portable electronic devices.
Professor Jeung Ku Kang and his team from the Graduate School of Energy, Environment, Water, and Sustainability developed this hybrid energy storage with high energy and power densities along over a long cycle life by assembling fibre-like polymer chain anodes and sub-nanoscale metal oxide cathodes on graphene.
Conventional aqueous electrolyte-based energy storage devices have a limitation for boosting charges and high energy density due to low driving voltage and a shortage of anode materials.
Energy storage device capacity is determined by the two electrodes, and the balance between cathode and anode leads to high stability. In general, two electrodes show differences in electrical properties and differ in ion storage mechanism processes, resulting in poor storage and stability from the imbalance.
The research team came up with new structures and materials to facilitate rapid speed in energy exchange on the surfaces of the electrodes and minimize the energy loss between the two electrodes.
The team made anodes with graphene-based polymer chain materials. The web-like structure of graphene leads to a high surface area, thereby allowing higher capacitance.
For cathode materials, the team used metal oxide in sub-nanoscale structures to elevate atom-by-ion redox reactions. This method realized higher energy density and faster energy exchange while minimizing energy loss.
The developed device can be charged within 20 to 30 seconds using a low-power charging system, such as a USB switching charger or a flexible photovoltaic cell. The developed aqueous hybrid energy device shows more than 100-fold higher power density compared to conventional aqueous batteries and can be rapidly recharged. Further, the device showed high stability with its capacity maintained at 100% at a high charge/discharge current.
Professor Kang said, “This eco-friendly technology can be easily manufactured and is highly applicable. In particular, its high capacity and high stability, compared to existing technologies, could contribute to the commercialization of aqueous capacitors. The device can be rapidly charged using a low-power charging system, and thus can be applied to portable electronic device.”
This research, led by a PhD candidate Il Woo Ock, was published in Advanced Energy Materials on January 15.

Samsung Electronics' Chairman Kwon Becomes the First Alumnus Honorary Doctorate
(Samsung Electronics' Chairman & CEO Kwon,left, and President Shin)
The semiconductor has bred innovation in Korea, as one of the staples of economic growth. Without the success of the semiconductor industry of Korea, it is hard to imagine the high tech dominance in the global market enjoyed by Korean companies.
It is said that one in every four Ph.D.s working in the semiconductor industry of Korea graduated from KAIST. Among them, Chairman and CEO Oh-Hyun Kwon of Samsung Electronics, Class of 1977, has arrived at the epitome of this top industry.
KAIST’s class of 1977 produced many movers and shakers in Korea’s innovation efforts. Now in their mid-60s, they were the players who embodied Korea’s ICT and helped it become a global powerhouse. They are the ones who worked for and witnessed the socio-economic transformation of Korea through innovation.
In recognition of his unsurpassable entrepreneurship, which made the remarkable strides in the semiconductor and electronics industry in Korea and beyond, Chairman Kwon was honored as the first recipient of an honorary doctorate from his alma mater on February 23 during the 2018 commencement ceremony.
After completing his Master's in Electrical Engineering at KAIST in 1977, he earned his Ph.D. in Electrical Engineering from Stanford University. The first honorary degree bestowed to an alumnus was conferred by the first alumnus President of KAIST Sung-Chul Shin. President Shin said that Chairman Kwon’s exceptional leadership has inspired the KAIST community and exemplified the spirit of KAIST.
Currently serving as chairman & CEO of Samsung Electronics and Samsung Advanced Institute of Technology (SAIT), Kwon has worked for Samsung in a variety of key positions in their semiconductor division since 1985.
In the mid-1980s, Japan was leading the global semiconductor market. At Samsung, Chairman Kwon, who was in charge of the memory semiconductor team, successfully developed 4M DRAM. Later in 1992, he played a leading role in the development of the world’s first 64M DRAM.
The success of 4M DRAM and 64M DRAM led Samsung to clinch the top position in the DRAM and NAND flash business around the world. This helped Samsung emerge as a global leader in the semiconductor industry.
As a result, Samsung, as well as the national economy, could gain significant momentum to build national competitiveness and economic growth. The outstanding technological leadership of Chairman Kwon led to the development of proprietary semiconductor design and processes technologies as well as numerous patents.
He also played a leadership role in creating a mutual growth environment among conglomerates rather than merely engaging in direct competition. Chairman Kwon made every effort to establish the cornerstone of mutual growth, especially in relationships with small and medium-sized enterprises (SMEs). His win-win collaboration initiatives among conglomerates and SMEs made a significant impact on the development of the entire industry of Korea.
In his acceptance speech, he charged the graduates to embrace challenges, to collaborate with peers, and create their own future.
The full text of his speech is printed below.
Graduates and distinguished guests! I extend my sincere congratulations to my fellow graduates, as you are awarded degrees for your deep efforts, as well as to the parents and family members who have supported you.
In 1977, I received my Master’s degree in Electrical Engineering from KAIST. Today, as the first honorary doctor among KAIST graduates, I am truly honored to be here. I am deeply grateful to all of you, including President Sung-Chul Shin and the Chairman of the Board of Trustees, Jang-Moo Lee.
Today, I want to tell you about the experiences and lessons I have learned from my 40 years of corporate management experience.
First, you should lead and drive changes by yourself. In the process of realizing a dream, the situation and circumstances do not always proceed as you planned.
I started my career as a researcher. However, I had to continuously transform myself into a project leader, business team leader, and CEO. It was challenging every time, due to a lack of preparing and my insufficient ability. However, I have always accomplished the intended goal through the mindset of embracing changes and studying new things.
It is said that the survivors are not always the strongest nor the most intelligent, but the ones who are the most adaptive to changes. We can only be the last survivor if we have the character to see those small signs that signal changes are coming and cope with changes well. Take changes positively and actively and then, transform yourself to match a given situation.
In addition, it is important to understand others. When it comes to one’s career, there is nothing that you can do alone without the assistance of others. If it is not possible to do everything by yourself, you will need to supplement your efforts through the help of others. To do this, you need to understand your colleagues, bosses, and customers first.
People, who work in tech tend to cage themselves in their own silos. But in an era of destructive innovation, where boundaries of industries and technologies are collapsing at a breakneck pace, scientists also need to enhance their understanding of various areas such as culture, art, and the humanities.
This is a famous verse from a poem by Chun-Soo Kim.
Before I called his name,
He was nothing but a gesture.
When I called his name, He came to me and became a flower.
Make wonderful synergy by making your partner a flower and complementing each other. When you first notice the true value of another person and interact with them, the value of the individual will be doubled and will bring about a greater impact.
Finally, we all need to cooperate with each other. All of you here, including myself, are people who have benefited from society. We must cooperate with each other and give back to society for the best results.
A biologist once said that incremental evolution comes from competition, but fundamental evolution comes from cooperation. Great leaders should achieve results through cooperation rather than competition.
You are the future leaders with top-class knowledge. I hope you will become great leaders who have wisdom that combines external resources with your abilities.
Now, graduates of 2018 who are standing at the starting line, we often worry about an unpredictable tomorrow. However, the smartest way to predict the future is to create the future for ourselves. Moreover, we can try again even though we sometimes make mistakes. I urge you to make future you are hoping for.
Once again, I would like to thank you for this honorary doctorate and extend my sincere wishes for the endless development of KAIST and the best of luck to the futures of these graduates. Thank you.

During the commencement speech, Kwon and President Shin both highlighted the importance of collaboration instead of competition.
Kwon encouraged the graduates to understand others to make wonderful synergy. “When you first notice the true value of another person and interact with them, the value of the individual will be doubled and will bring about a greater impact,” he said.
Also, he stressed having a collaborative mindset by saying, “All of you here, including myself, are people who have benefited from society. We must cooperate with each other and give back to society for the vest results.”
While highlighting the core values of KAIST, creativity, challenge and caring, President Shin also emphasized collaboration with others. He said, “In the future, expertise in a single discipline will not lead to new inventions or discoveries. This highlights the importance of multidisciplinary, convergence research. The key to success lies in the acknowledgement of your peers as partners for mutual growth. Your partners will make up your weak areas and become your most important asset. May you expand your personal network by finding valuable partners not only within your laboratory and workplace, but beyond Korea.”
“Go out into the world and change it as a global shaper, global innovator, and global mover. I hope that each and every one of you will add benefits the world and your legacy will be remembered for generations to come. This is your obligation as a graduate of KAIST,” he said.

Soul-Searching & Odds-Defying Determination: A Commencement Story of Dr. Tae-Hyun Oh
(Dr. Tae-Hyun Oh, one of the 2736 graduates of the 2018)
Each and every one of the 2,736 graduates has come a long way to the 2018 Commencement. Tae-Hyun Oh, who just started his new research career at MIT after completing his Ph.D. at KAIST, is no exception.
Unlike the most KAIST freshmen straight out of the ingenious science academies of Korea, he is among the many who endured very challenging and turbulent adolescent years. Buffeted by family instability and struggling during his time at school, he saw himself trapped by seemingly impenetrable barriers. His mother, who hated to see his struggling, advised him to take a break to reflect on who he is and what he wanted to do.
After dropping out of high school in his first year, ways to make money and support his family occupied his thoughts. He took on odd jobs from a car body shop to a gas station, but the real world was very tough and sometimes even cruel to the high school dropout.
Bias and prejudice stigmatizing dropouts hurt him so much. He often overheard a parent who dropped by the body shop that he worked in saying, “If you do not study hard, you will end up like this guy.” Hearing such things terrified him and awoke his sense of purpose. So he decided to do something meaningful and be a better man than he was.
“I didn’t like the person I was growing up to become. I needed to find myself and get away from the place I was growing up. It was my adventure and it was the best decision I ever made,” says Oh.
After completing his high school diploma national certificate, he planned to apply to an engineering college. On his second try, he gained admission into the Department of Electrical Engineering at Kwang Woon University with a full scholarship. He was so thrilled for this opportunity and hoped he could do well at college. Signal processing and image processing became the interest of his research and he finished his undergraduate degree summa cum laude.
Gaining confidence in his studies, he searched around graduate school department websites in Korea to select the path he was interested in. Among others, the Robotics and Computer Vision Lab of Professor In-So Kweon at the Department of Electrical Engineering at KAIST was attractive to him.
Professor Kweon’s lab is globally renowned for robot vision technology. Their technologies were applied into HUBO, the KAIST-developed bimodal humanoid robot that won the 2015 DARPA Challenges.
“I am so appreciate of Professor Kweon, who accepted and guided me,” he said. Under Professor Kweon’s advising, he could finish his Master’s and Ph.D. courses in seven years. The mathematical modeling on fundamental computer algorithms became his main research topic.
While at KAIST, his academic research has blossomed. He won a total of 13 research prizes sponsored by corporations at home and abroad such as Kolon, Samsung, Hyundai Motors, and Qualcomm.
In 2015, he won the Microsoft Research Asia Fellowship as the sole Korean among 13 Ph.D. candidates in the Asian region. With the MSRA fellowship, he could intern at the MS Research Beijing Office for half a year and then in Redmond, Washington in the US.
“Professor Kweon’s lab filled me up with knowledge. Whenever I presented our team’s paper at an international conference, I was amazed by the strong interest shown by foreign experts, researchers, and professors. Their strong support and interest encouraged me a lot. I was fully charged with the belief that I could go abroad and explore more opportunities,” he said.
Dr. Oh, who completed his dissertation last fall, now works at the Department of Electrical Engineering and Computer Science at MIT under Professor Wojciech Matusik.
“I think the research environment at KAIST is on par with MIT. I have very rich resources for my studies and research at both schools, but at MIT the working culture is a little different and it remains a big challenge for me. I am still not familiar with collaborative work with colleagues from very diverse backgrounds and countries, and to persuade them and communicate with them is very tough. But I think I am getting better and better,” he said.
Oh, who is an avid computer game player as well, said life seems to be a game. The level of the game will be upgraded to the next level after something is accomplished. He feels great joy when he is moving up and he believes such diverse experiences have helped him become a better person day by day. Once he identified what gave him a strong sense of purpose, he wasn’t stressed out by his studies any more. He was so excited to be able to follow his passion and is ready for the next challenge.

KAIST, First to Win the Cube Satellite Competition
Professor Hyochoong Bang from the Department of Aerospace Engineering and his team received the Minister of Science and ICT Award at the 1st Cube Satellite Competition.
The team actually participated in the competition in 2012, but it took several years for the awarding ceremony since it took years for the satellites to be designed, produced, and launched.
The KAIST team successfully developed a cube satellite, named ‘Little Intelligent Nanosatellite of KAIST (LINK)’ and completed its launch in April 2017.
LINK (size: 20cmx10cmx10cm, weight: 2kg) mounted mass spectrometry and Langmuir probe for Earth observation. The Langmuir probe was developed by Professor Kyoung Wook Min from the Department of Physics, KAIST.
Yeerang Lim, a PhD student from the Department of Aerospace Engineering said, “I still remember the feeling that I had on the day when LINK launched into orbit and sent back signals. I hope that space exploration is not something far away but attainable for us in near future.”
