Mobile Clinic Module Wins Red Dot and iF Design Awards
The Mobile Clinic Module (MCM), an inflatable negative pressure ward building system developed by the Korea Aid for Respiratory Epidemic (KARE) initiative at KAIST, gained international acclaim by winning the prestigious Red Dot Design Award and iF Design Award.
The MCM was recognized as one of the Red Dot Product Designs of the Year. It also won four iF Design Awards in communication design, interior architecture, user interface, and user experience. Winning the two most influential design awards demonstrates how product design can make a valuable contribution to help contain pandemics and reflects new consumer trends for dealing with pandemics.
Designed to be patient friendly, even in the extreme medical situations such as pandemics or triage, the MCM is the result of collaborations among researchers in a variety of fields including mechanical engineering, computing, industrial and systems engineering, medical hospitals, and engineering companies. The research team was led by Professor Tek-Jin Nam from the Department of Industrial Design.
The MCM is expandable, moveable, and easy to store through a combination of negative pressure frames, air tents, and multi-functional panels. Positive air pressure devices supply fresh air from outside the tent. An air pump and controller maintain air beam pressure, while filtering exhausted air from inside. An internal air information monitoring system efficiently controls inside air pressure and purifies the air. It requires only one-fourth of the volume of existing wards and takes up approximately 40% of their weight. The unit can be transported in a 40-foot container truck.
MCMs are now located at the Korea Institute of Radiological & Medical Sciences and Jeju Vaccine Center and expect to be used at many other facilities. KARE is developing antiviral solutions and devices such as protective gear, sterilizers, and test kits to promptly respond to the pandemic. More than 100 researchers at KAIST are collaborating with industry and clinical hospitals to develop antiviral technologies that will improve preventive measures, diagnoses, and treatments.
Professor Nam said, “Our designers will continue to identify the most challenging issues, and try to resolve them by realizing user-friendly functions. We believe this will significantly contribute to relieving the drastic need for negative pressure beds and provide a place for monitoring patients with moderate symptoms. We look forward to the MCM upgrading epidemic management resources around the globe.”

COVID-Update: KAIST on High Alert amid Spring Resurgence
COVID-19 Task Force responds 24-7 and ISSS provides returning international students with a comfort package during 14-day mandatory quarantine
In response to the upsurge of COVID-19 cases in the proximate college districts in Daejeon, KAIST announced the enforcement of stricter health and safety regulations. Korean health authorities expected another surge of COVID-19 cases this spring as Korea’s daily new COVID-19 cases have rebounded to the high 600s and over 700 in April, which is the most in over three months.
New guidelines issued on April 5 banned faculty, staff, and students from engaging in off-campus activities and utilizing external public facilities. Such facilities include, but are not limited to, bars, cafes, clubs, gyms, karaoke rooms, PC rooms, restaurants, and other crowded indoor spaces. All class and research activities, work meetings, and school events were moved exclusively online, and working from home and flexible working hours were highly encouraged in order to minimize face-to-face interactions on campus. In particular, having meals outside of KAIST cafeterias in groups of two or more was prohibited, while food delivery and take-outs were allowed.
Executive Vice President and Provost Seung Seob Lee said in a letter to the KAIST community on April 5 that “the school considers the risk of the current situation to be very high, likely the highest since the outbreak of COVID-19.” Provost Lee then called for more team efforts to contain the current phase of the pandemic and asked everyone to do their part.
The school installed new temperature scanners equipped with hand sanitizer dispensers in front of the dormitory entrances to further control the spread of the disease on campus, following confirmed COVID-19 cases among dormitory residents.
As the COVID-19 pandemic continues with no clear end in sight, the Task Force for the Prevention of COVID-19 and the International Scholar and Student Services (ISSS) Team at KAIST are working around the clock to reduce the risk of infection spread not only within the campus, but also coming from outside the campus.
Under strict health and safety guidelines, KAIST has allowed international students to come back to campus. Currently about 600 international students, mostly graduate students reside on campus. All returning students should complete the mandatory 14-day self-quarantine required by the Korean government at their own expense.
The KAIST COVID-19 Task Force is in charge of enacting on-campus health and safety guidelines, responding to reports and inquiries from the KAIST community 24-7, and controlling outsider access, among other responsibilities.
The ISSS Team requires returning international students to fill out an entry authorization form and receive approval from the KAIST COVID-19 Task Force prior to returning to campus from their home countries. Once students arrive at their designated quarantine facility, the KAIST ISSS Team sends care packages, which includes some toiletries, instant food, a multipot, a thermometer, and other daily necessities. During the quarantine period, returning students are also advised to follow the directions given by government officials and to coordinate with the ISSS Team. The team also provides useful Korean phrases for international students to help them with communication.
The self-quarantine period ends at 12 p.m. 14 days after arrival. Within two days of finishing the 14 days of self-isolation, these students are required to undergo a polymerase chain reaction (PCR) test for COVID-19 at the nearest health center. After confirmed negative, they are allowed to move into on-campus accommodations. KAIST will maintain the current method of remote education and distancing methods until further notice.

Microbial Production of a Natural Red Colorant Carminic Acid
Metabolic engineering and computer-simulated enzyme engineering led to the production of carminic acid, a natural red colorant, from bacteria for the first time
A research group at KAIST has engineered a bacterium capable of producing a natural red colorant, carminic acid, which is widely used for food and cosmetics. The research team reported the complete biosynthesis of carminic acid from glucose in engineered Escherichia coli. The strategies will be useful for the design and construction of biosynthetic pathways involving unknown enzymes and consequently the production of diverse industrially important natural products for the food, pharmaceutical, and cosmetic industries.
Carminic acid is a natural red colorant widely being used for products such as strawberry milk and lipstick. However, carminic acid has been produced by farming cochineals, a scale insect which only grows in the region around Peru and Canary Islands, followed by complicated multi-step purification processes. Moreover, carminic acid often contains protein contaminants that cause allergies so many people are unwilling to consume products made of insect-driven colorants. On that account, manufacturers around the world are using alternative red colorants despite the fact that carminic acid is one of the most stable natural red colorants.
These challenges inspired the metabolic engineering research group at KAIST to address this issue. Its members include postdoctoral researchers Dongsoo Yang and Woo Dae Jang, and Distinguished Professor Sang Yup Lee of the Department of Chemical and Biomolecular Engineering. This study entitled “Production of carminic acid by metabolically engineered Escherichia coli” was published online in the Journal of the American Chemical Society (JACS) on April 2.
This research reports for the first time the development of a bacterial strain capable of producing carminic acid from glucose via metabolic engineering and computer simulation-assisted enzyme engineering. The research group optimized the type II polyketide synthase machinery to efficiently produce the precursor of carminic acid, flavokermesic acid.
Since the enzymes responsible for the remaining two reactions were neither discovered nor functional, biochemical reaction analysis was performed to identify enzymes that can convert flavokermesic acid into carminic acid. Then, homology modeling and docking simulations were performed to enhance the activities of the two identified enzymes. The team could confirm that the final engineered strain could produce carminic acid directly from glucose. The C-glucosyltransferase developed in this study was found to be generally applicable for other natural products as showcased by the successful production of an additional product, aloesin, which is found in aloe leaves.
“The most important part of this research is that unknown enzymes for the production of target natural products were identified and improved by biochemical reaction analyses and computer simulation-assisted enzyme engineering,” says Dr. Dongsoo Yang. He explained the development of a generally applicable C-glucosyltransferase is also useful since C-glucosylation is a relatively unexplored reaction in bacteria including Escherichia coli. Using the C-glucosyltransferase developed in this study, both carminic acid and aloesin were successfully produced from glucose.
“A sustainable and insect-free method of producing carminic acid was achieved for the first time in this study. Unknown or inefficient enzymes have always been a major problem in natural product biosynthesis, and here we suggest one effective solution for solving this problem. As maintaining good health in the aging society is becoming increasingly important, we expect that the technology and strategies developed here will play pivotal roles in producing other valuable natural products of medical or nutritional importance,” said Distinguished Professor Sang Yup Lee.
This work was supported by the Technology Development Program to Solve Climate Changes on Systems Metabolic Engineering for Biorefineries of the Ministry of Science and ICT (MSIT) through the National Research Foundation (NRF) of Korea and the KAIST Cross-Generation Collaborative Lab project; Sang Yup Lee and Dongsoo Yang were also supported by Novo Nordisk Foundation in Denmark.

Streamlining the Process of Materials Discovery
The materials platform M3I3 reduces the time for materials discovery by reverse engineering future materials using multiscale/multimodal imaging and machine learning of the processing-structure-properties relationship
Developing new materials and novel processes has continued to change the world. The M3I3 Initiative at KAIST has led to new insights into advancing materials development by implementing breakthroughs in materials imaging that have created a paradigm shift in the discovery of materials. The Initiative features the multiscale modeling and imaging of structure and property relationships and materials hierarchies combined with the latest material-processing data.
The research team led by Professor Seungbum Hong analyzed the materials research projects reported by leading global institutes and research groups, and derived a quantitative model using machine learning with a scientific interpretation. This process embodies the research goal of the M3I3: Materials and Molecular Modeling, Imaging, Informatics and Integration.
The researchers discussed the role of multiscale materials and molecular imaging combined with machine learning and also presented a future outlook for developments and the major challenges of M3I3. By building this model, the research team envisions creating desired sets of properties for materials and obtaining the optimum processing recipes to synthesize them.
“The development of various microscopy and diffraction tools with the ability to map the structure, property, and performance of materials at multiscale levels and in real time enabled us to think that materials imaging could radically accelerate materials discovery and development,” says Professor Hong.
“We plan to build an M3I3 repository of searchable structural and property maps using FAIR (Findable, Accessible, Interoperable, and Reusable) principles to standardize best practices as well as streamline the training of early career researchers.”
One of the examples that shows the power of structure-property imaging at the nanoscale is the development of future materials for emerging nonvolatile memory devices. Specifically, the research team focused on microscopy using photons, electrons, and physical probes on the multiscale structural hierarchy, as well as structure-property relationships to enhance the performance of memory devices.
“M3I3 is an algorithm for performing the reverse engineering of future materials. Reverse engineering starts by analyzing the structure and composition of cutting-edge materials or products. Once the research team determines the performance of our targeted future materials, we need to know the candidate structures and compositions for producing the future materials.”
The research team has built a data-driven experimental design based on traditional NCM (nickel, cobalt, and manganese) cathode materials. With this, the research team expanded their future direction for achieving even higher discharge capacity, which can be realized via Li-rich cathodes.
However, one of the major challenges was the limitation of available data that describes the Li-rich cathode properties. To mitigate this problem, the researchers proposed two solutions: First, they should build a machine-learning-guided data generator for data augmentation. Second, they would use a machine-learning method based on ‘transfer learning.’ Since the NCM cathode database shares a common feature with a Li-rich cathode, one could consider repurposing the NCM trained model for assisting the Li-rich prediction. With the pretrained model and transfer learning, the team expects to achieve outstanding predictions for Li-rich cathodes even with the small data set.
With advances in experimental imaging and the availability of well-resolved information and big data, along with significant advances in high-performance computing and a worldwide thrust toward a general, collaborative, integrative, and on-demand research platform, there is a clear confluence in the required capabilities of advancing the M3I3 Initiative.
Professor Hong said, “Once we succeed in using the inverse “property−structure−processing” solver to develop cathode, anode, electrolyte, and membrane materials for high energy density Li-ion batteries, we will expand our scope of materials to battery/fuel cells, aerospace, automobiles, food, medicine, and cosmetic materials.”
The review was published in ACS Nano in March. This study was conducted through collaborations with Dr. Chi Hao Liow, Professor Jong Min Yuk, Professor Hye Ryung Byon, Professor Yongsoo Yang, Professor EunAe Cho, Professor Pyuck-Pa Choi, and Professor Hyuck Mo Lee at KAIST, Professor Joshua C. Agar at Lehigh University, Dr. Sergei V. Kalinin at Oak Ridge National Laboratory, Professor Peter W. Voorhees at Northwestern University, and Professor Peter Littlewood at the University of Chicago (Article title: Reducing Time to Discovery: Materials and Molecular Modeling, Imaging, Informatics, and Integration).This work was supported by the KAIST Global Singularity Research Program for 2019 and 2020.

Upbeat Message for a New Future at President Lee’s Inauguration
KAIST’s 17th President Kwang Hyung Lee reaffirmed his commitment to building a new future preparing for the post-AI era during his inauguration on March 8. The Board of Trustees selected the former provost and executive vice president as the new president, succeeding 16th President Sung-Chul Shin whose four-year term expired last month.
In his inaugural address, President Lee proposed a new culture strategy, ‘QAIST’ designed to foster more creative talents and ensure innovative research infrastructure. He said that the best way to stand out as a leading global university is to carve out our own distinctness.
The ceremony was live streamed via YouTube due to the social distancing guidelines, with a very limited number of distinguished guests attending. Among them were President Lee’s former student Jung-Ju Kim who started Nexon, now the world’s most popular online game company, and former Chairman of the Board of Trustees Moon-Soul Chung who President Lee worked with when he made the endowment for establishing the Department of Bio and Brain Engineering in 2001 and the Moon Soul Graduate School of Future Strategy in 2013.
In his induction speech, Chairman Woo Sik Kim of the Board of Trustees said that President Lee is a proven leader who has deep insight and passion and he will help KAIST make a new leap forward. “I believe that Professor Lee will be the right leader at this critical moment for the university, ushering in a new future for KAIST as it turns 50 this year.”
President Lee explained that for the next 50 years, KAIST should double down to identify the challenges humanity faces, then define and resolve them with unyielding innovations in education, research, technology commercialization, and internationalization.
“We definitely should pull together to produce sustainable global value that will serve the prosperity and happiness of all humanity, not only our nation. We will become one of the top 10 universities in the world when we realize all these goals. We can live up to the people’s expectations by producing creative global talent, staying ahead of new research topics, and producing corporations that will lead the nation’s industries.”
“To this end, I will continue to strive to help us achieve our mission of becoming a ‘Global Value Creative Leading University’ as described in KAIST Vision 2031. I will do my utmost to bring about the ‘KAIST New Culture Strategy, QAIST’ for a post-AI era.”
He added that he would like to inspire students and faculty to have more humanistic approaches in their education and learning. The ‘Q’ in “QAIST” refers to questioning. President Lee believes that the learning starts with questions and being curious about something. “We will innovate the educational system to have them question everything.”
Then, he said that he will focus on ‘A’dvanced research to prepare for the post AI-era. “We should be the first mover who can define and solve new problems. It’s more important to be the ‘first’ one than the ‘best’ one.” He also said he will create a new culture that failing would not be stigmatized, offering more chances after failing.
‘I’nternationalization is another vision the new president will continue to pursue. He plans to embrace greater diversity on the campus to achieve goals of 15% international faculty, 25% female faculty, and 15% international students by reshaping the recruiting policy. He will continue to expand KAIST campuses overseas.
‘S’tartup and technology commercialization will be the crucial areas where the president will make innovations. “I will fully support any startups at KAIST. I encourage every lab to start a startup,” he stressed. President Lee said he plans to increase KAIST’s annual revenue from technology commercialization fees to 100 billion KRW in 10 years, a step to secure financial independence. He plans to privatize the Institute of Technology Value Creation, which is responsible for technology commercialization at KAIST to enhance its competitiveness.
‘T’rust building is the prerequisite value for creating transparent and reliable management in finance and HR. President Lee said he would like to make a new organizational culture that will be more ethical, responsible, and autonomous with a high standard of integrity.
His predecessor, President Sung-Chul Shin lauded his successor in his congratulatory speech saying, “He is a president prepared for this job.”
“I have known him for more than 30 years. He is a man of action. With unparalleled ideas and prompt execution, he carried out all his duties efficiently for the Committee of Vision 2031 that he chaired, and played a central role in establishing the full vision of KAIST. First and foremost, he is a man of great passion, with a firm vision but a warm heart.”
Nexon founder and Chairman Jung-Ju Kim also made an emotional tribute to his former professor. Holding back tears, he said, “I was not a good student. I was struggling in my graduate courses so I had to drop out of my PhD course. But Professor Lee and his wife never gave up on me. They were so kind to me and were always encouraging despite my disappointing days. I am now ready to do something good for KAIST, for Professor Lee, and for the future of our society. I believe that President Lee will guide us down the new path for KAIST.” IDIS Holdings CEO Young-Dal Kim also attended the ceremony to congratulate his former professor on his inauguration.

Ushering in a New Era at the 50th Innoversary Ceremony
President Moon Jae-In declares KAIST the future of Korea
KAIST reaffirmed its goal of becoming an institute that can serve the world for the next century, marking its 50th anniversary on February 16. The KAIST community and distinguished guests gathered online during the official ceremony to commemorate KAIST’s anniversary and envisioned ways to serve the world, a major shift from its founding mission focusing on national growth.
The ceremony celebrated the legacy of KAIST, which has become a trailblazer by fostering the most competent scientists and engineers and making breakthroughs which led to the nation becoming a global high-tech leader.
President Moon Jae-In applauded KAIST as “the future of Korea” in his online congratulatory message, saying that “KAIST has made us feel proud when the nation stays ahead in science and technology. The dream of KAIST has been the dream of Korea. The passion of KAIST has been the passion of Korea. KAIST is the future of Korea.”
“KAIST has overcome challenges and created innovations for advancing the nation, from the first internet network to launching our first satellite in the early 80s to the Mobile Clinic Module (MCM), a negative pressure ward module in response to COVID-19. Whenever the nation faced a challenge, KAIST was there.”
President Moon also asked KAIST researchers to find sustainable ways to balance nature and humanity in this time of climate change and the Fourth Industrial Revolution.
Executive Chairman of the World Economic Forum Dr.Klaus Schwab also congratulated, saying "KAIST is a leader in ensuring social inclusion. Founded with the support of USAID, today it is paying it forward and sharing the same support through the Kenya-KAIST project."
The ceremony first brought Dr. KunMo Chung to the stage, the man who proposed the idea of founding the first advanced science and technology institute in Korea. His proposal to the then administrator of USAID John Hannah resulted in the Korean government meriting a 6 million USD loan for to start KAIST. He was the only Korean member of the USAID feasibility study team led by Dr. Frederick Terman, the former vice president of Stanford University. Dr. Chung wrote the Terman Report, which gave a green light to the establishment of KAIST in Korea in 1970.
Dr. Chung said the nation’s strong desire to escape from poverty through the advancement of science and technology was thoroughly realized by KAIST. “The Terman Report’s vision was perfectly realized. Now it’s time to envision the next dream of KAIST for another century.”
President Sung-Chul Shin said in his anniversary speech that KAIST has now transformed into a university that will serve the all of humanity by advancing science and technology while fostering new talents best fit for the new global environment.

COVID-Update: Spring 2021 Classes Continue Online
KAIST announced that its spring 2021 classes will also be online as the pandemic continues into the new year. The spring semester will begin on March 1.
Executive Vice President and Provost Kwang Hyung Lee said in a letter to the KAIST community on January 15 that nearly all classes in the 2021 spring semester will be held online. However, a very limited number of lab classes and other classes that require on-site practice and demonstrations will be offered either in-person or in a blended format. In addition, graduate courses above the 600 level and graduate courses in the College of Business at the Seoul campus will be allowed to conduct in-person or blended classes under very strict social distancing guidelines.
Provost Lee said that the university will be revert back to in-person classes as soon as the government eases the social distancing guidelines. As of February 4, the nation is under Level 2.5 in Seoul and its metropolitan areas, while other regions are at Level 2. Level 2.5 prohibits the gathering of 10 or more people, and Levels 1 and 2 require gatherings to be fewer than 50 people. At Level 3, all classes will be held online.
Test management is another challenge. Regarding mid-term and final exams, the university plans to give more flexibility to professors. Professors may give additional assignments instead of a mid-term exam. Open-book exams and real-time exams through Zoom will be another option. However, some classes that require in-person tests in some graduate courses will be allowed as long as they follow very strict social distancing guidelines.

Highly Deformable Piezoelectric Nanotruss for Tactile Electronics
With the importance of non-contact environments growing due to COVID-19, tactile electronic devices using haptic technology are gaining traction as new mediums of communication.
Haptic technology is being applied in a wide array of fields such as robotics or interactive displays. haptic gloves are being used for augmented information communication technology. Efficient piezoelectric materials that can convert various mechanical stimuli into electrical signals and vice versa are a prerequisite for advancing high-performing haptic technology.
A research team led by Professor Seungbum Hong confirmed the potential of tactile devices by developing ceramic piezoelectric materials that are three times more deformable. For the fabrication of highly deformable nanomaterials, the research team built a zinc oxide hollow nanostructure using proximity field nanopatterning and atomic layered deposition. The piezoelectric coefficient was measured to be approximately 9.2 pm/V and the nanopillar compression test showed an elastic strain limit of approximately 10%, which is more than three times greater than that of the bulk zinc oxide one.
Piezoelectric ceramics have a high piezoelectric coefficient with a low elastic strain limit, whereas the opposite is true for piezoelectric polymers. Therefore, it has been very challenging to obtain good performance in both high piezoelectric coefficients as well as high elastic strain limits. To break the elastic limit of piezoelectric ceramics, the research team introduced a 3D truss-like hollow nanostructure with nanometer-scale thin walls.
According to the Griffith criterion, the fracture strength of a material is inversely proportional to the square root of the preexisting flaw size. However, a large flaw is less likely to occur in a small structure, which, in turn, enhances the strength of the material. Therefore, implementing the form of a 3D truss-like hollow nanostructure with nanometer-scale thin walls can extend the elastic limit of the material. Furthermore, a monolithic 3D structure can withstand large strains in all directions while simultaneously preventing the loss from the bottleneck. Previously, the fracture property of piezoelectric ceramic materials was difficult to control, owing to the large variance in crack sizes. However, the research team structurally limited the crack sizes to manage the fracture properties.
Professor Hong’s results demonstrate the potential for the development of highly deformable ceramic piezoelectric materials by improving the elastic limit using a 3D hollow nanostructure. Since zinc oxide has a relatively low piezoelectric coefficient compared to other piezoelectric ceramic materials, applying the proposed structure to such components promised better results in terms of the piezoelectric activity.
“With the advent of the non-contact era, the importance of emotional communication is increasing. Through the development of novel tactile interaction technologies, in addition to the current visual and auditory communication, mankind will enter a new era where they can communicate with anyone using all five senses regardless of location as if they are with them in person,” Professor Hong said.
“While additional research must be conducted to realize the application of the proposed designs for haptic enhancement devices, this study holds high value in that it resolves one of the most challenging issues in the use of piezoelectric ceramics, specifically opening new possibilities for their application by overcoming their mechanical constraints.
The research was reported in Nano Energy and supported by the Ministry of Science and ICT, the Korea Research Foundation, and the KAIST Global Singularity Research Project.
