Hanmaeum Education Corps Invites Multicultural Families
About 100 graduates from the Multicultural Mother Schools and their families visited the KAIST campus on October 29 at the invitation of the Hanmaeum Education Corps of KAIST. The Hanmanum Education Corps is a volunteering organization composed of KAIST faculty and students. Many retired KAIST faculties are also members of the corps. Byong Kyu Choi, an Emeritus Professor from the Department of Industrial and Systems Engineering, is the director of the corps and has been leading the event since 2015.
With the support of a KAIST educational volunteering organization called SEED(Social Education Embracing Diversity), this year’s event offered various activities including a treasure hunt and convergent science programs. Participants had the opportunity to experience KAIST’s educational environment and enjoyed the perfect autumn weather during outdoor activities with student volunteers.
Children enjoyed making illumination-music stickers with the KAIST students, even though it was tough to learn at first.
While the children engaged themselves in the science program, parents visited the chrysanthemum fair and some of KAIST’s cafeterias.
Hanmaeum Education Corps opened the Multicultural Mother Schools to support multicultural mothers so that they can have more interest in and help their children more with their education. Since its establishment in 2015, the Multicultural Mother Schools have been expanding throughout the country.
The corporation hopes that visiting a renowned university will encourage children from multicultural families to study hard in addition to offering self-enrichment opportunities through career exploration and science activities.

Development of a Highly-Accurate Computational Model of Human Metabolism
A research team from KAIST developed a computational framework that enables the reconstruction of a comprehensive computational model of human metabolism, which allows for an accurate prediction of personal metabolic features (or phenotypes).
Understanding personal metabolic phenotypes allows us to design effective therapeutic strategies for various chronic and infectious diseases. A human computational model called the genome-scale metabolic model (GEM) contains information on thousands of metabolic genes and their corresponding reactions and metabolites, and has played an important role in predicting metabolic phenotypes. Although several versions of human GEMs have been released, they had room for further development, especially as to incorporating biological information coming from a human genetics mechanism called “alternative splicing.” Alternative splicing is a genetic mechanism that allows a gene to give rise to multiple reactions, and is strongly associated with pathology.
To tackle this problem, Jae Yong Ryu (a Ph.D. student), Dr. Hyun Uk Kim (Research Fellow), and Distinguished Professor Sang Yup Lee, all from the Department of Chemical and Biomolecular Engineering at KAIST, developed a computational framework that systematically generates metabolic reactions, and adds them to the human GEM. The resulting human GEM was demonstrated to accurately predict metabolic phenotypes under varied environmental conditions. The research results were published online in Proceedings of the National Academy of Sciences (PNAS) on October 24, 2017, under the title “Framework and resource for more than 11,000 gene-transcript-protein-reaction associations in human metabolism.”
The research team first updated the biological contents of a previous version of the human GEM. The updated biological contents include metabolic genes and their corresponding metabolites and reactions. In particular, metabolic reactions catalyzed by already-known protein isoforms were additionally incorporated into the human GEM; protein isoforms are multiple variants of proteins generated from individual genes through the alternative splicing process. Each protein isoform is often responsible for the operation of a metabolic reaction. Although multiple protein isoforms generated from one gene can play different functions by having different sets of protein domains and/or subcellular localizations, such information was not properly considered in previous versions of human GEMs.
Upon the initial update of the human GEM, named Recon 2M.1, the research team subsequently implemented a computational framework that systematically generates information on Gene-Transcript-Protein-Reaction Associations (GeTPRA) in order to identify protein isoforms that were previously not identified. This framework was developed in this study. As a result of the implementation of the framework for GeTPRA, more than 11,000 GeTPRA were automatically predicted, and thoroughly validated. Additional metabolic reactions were then added to Recon 2M.1 based on the predicted GeTPRA for the previously uncharacterized protein isoforms; Recon 2M.1 was renamed Recon 2M.2 from this upgrade.
Finally, Recon 2M.2 was integrated with 446 sets of personal biological data (RNA-Seq data) in order to build patient-specific cancer models. These patient-specific cancer models were used to predict cancer metabolism activities and anticancer targets.
The development of a new version of human GEMs along with the computational framework for GeTPRA is expected to boost studies in fundamental human genetics and medicine. Model files of the human GEMs Recon 2M.1 and 2M.2, a full list of the GeTPRA and the source code for the computational framework to predict the GeTPRA are all available as part of the publication of this study.
Distinguished Professor Lee said, “The predicted GeTPRA from the computational framework is expected to serve as a guideline for future experiments on human genetics and biochemistry, whereas the resulting Recon 2M.2 can be used to predict drug targets for various human diseases.”
This work was supported by the Technology Development Program to Solve Climate Changes on Systems Metabolic Engineering for Biorefineries (NRF-2012M1A2A2026556 and NRF-2012M1A2A2026557) from the Ministry of Science and ICT through the National Research Foundation (NRF) of Korea.

Peptide sequences of metabolic genes defined in Recon 2M.1 were retrieved from a database called Ensembl. EC numbers and subcellular localizations of all the protein isoforms of metabolic genes in Recon 2M.1 were predicted using software programs EFICAz2.5 and Wolf PSort, respectively. Information on the newly predicted GeTPRA was systematically incorporated into the Recon 2M.1, thereby resulting in Recon 2M.2.)

KAIST to Open the Meditation Research Center
KAIST announced that it will open its Meditation Research Center next June. The center will serve as a place for the wellness of KAIST community as well as for furthering the cognitive sciences and its relevant convergence studies.
For facilitating the center, KAIST signed an MOU with the Foundation Academia Platonica in Seoul, an academy working for enriching the humanities and insight meditation on Aug.31. The Venerable Misan, a Buddhist monk well-known for his ‘Heart Smile Meditation’ program, will head the center.
The center will also conduct convergence research on meditation, which will translate into brain imaging, cognitive behavior, and its psychological effects. Built upon the research, the center expects to publish textbooks on meditation and will distribute them to the public and schools in an effort to widely disseminate the benefits of meditation.
As mindful meditation has become mainstream and more extensively studied, growing evidence suggests multiple psychological and physical benefits of these mindfulness exercises as well as for similar practices. Mind-body practices like meditation have been shown to reduce the body’s stress response by strengthening the relaxation response and lowering stress hormones.
The Venerable Misan, a Ph.D in philosophy from Oxford University, also serves as the director of the Sangdo Meditation Center and a professor at Joong-Ang Sangha University, a higher educational institution for Buddhist monks.
Monk Misan said that meditation will play a crucial part in educating creative students with an empathetic mindset. He added, “Hi-tech companies in Silicon Valley such as Google and Intel have long introduced meditation programs for stress management. Such practices will enhance the wellness of employees as well as their working efficiency.”
President Sung-Chul Shin said of the opening of the center, “From long ago, many universities in foreign countries including Havard, Stanford, Oxfor universities and the Max Planck Institute in Germany have applied scientific approaches to meditation and installed meditation centers. I am pleased to open our own center next year and I believe that it will bring more diverse opportunities for advancing convergent studies in AI and cognitive sciences.

Students from Science Academies Shed a Light on KAIST
Recent KAIST statistics show that graduates from science academies distinguish themselves not only by their academic performance at KAIST but also in various professional careers after graduation.
Every year, approximately 20% of newly-enrolled students of KAIST are from science academies. In the case of the class of 2017, 170 students from science academies accounted for 22% of the newly-enrolled students. Moreover, they are forming a top-tier student group on campus. As shown in the table below, the ratio of students graduating early for either enrolling in graduate programs or landing a job indicates their excellent performance at KAIST.
There are eight science academies in Korea: Korea Science Academy of KAIST located in Busan, Seoul Science High School, Gyeonggi Science High School, Gwangju Science High School, Daejeon Science High School, Sejong Academy of Science and Arts, and Incheon Arts and Sciences Academy.
Recently, KAIST analyzed 532 university graduates from the class of 2012. It was found that 23 out of 63 graduates with the alma mater of science academies finished their degree early; as a result, the early graduation ratio of the class of 2012 stood at 36.5%. This percentage was significantly higher than that of students from other high schools.
Among the notable graduates, there was a student who made headlines with donation of 30 million KRW to KAIST. His donation was the largest donation from an enrolled student on record. His story goes back when Android smartphones were about to be distributed. Seung-Gyu Oh, then a student in the School of Electrical Engineering felt that existing subway apps were inconvenient, so he invented his own subway app that navigated the nearest subway lines in 2015. His app hit the market and ranked second in the subway app category. It had approximately five million users, which led to it generating advertising revenue. After the successful launch of the app, Oh accepted the takeover offered by Daum Kakao. He then donated 30 million KRW to his alma mater. “Since high school, I’ve always been thinking that I have received many benefits from my country and felt heavily responsible for it,” the alumnus of Korea Science of Academy and KAIST said. “I decided to make a donation to my alma mater, KAIST because I wanted to return what I had received from my country.” After graduation, Oh is now working for the web firm, Daum Kakao.
In May 24, 2017, the 41st International Collegiate Programming Contest, hosted by Association for Computing Machinery (ACM) and sponsored by IBM, was held in Rapid City, South Dakota in the US. It is a prestigious contest that has been held annually since 1977. College students from around the world participate in this contest; and in 2017, a total of 50,000 students from 2,900 universities in 104 countries participated in regional competitions, and approximately 400 students made it to the final round, entering into a fierce competition. KAIST students also participated in this contest. The team was comprised of Ji-Hoon Ko, Jong-Won Lee, and Han-Pil Kang from the School of Computing. They are also alumni of Gyeonggi Science High School. They received the ‘First Problem Solver’ award and a bronze medal which came with a 3,000 USD cash prize.
Sung-Jin Oh, who also graduated from Korea Science Academy of KAIST, is a research professor at the Korea Institute of Advanced Study (KIAS). He is the youngest recipient of the ‘Young Scientist Award’, which he received by proving a hypothesis from Einstein’s Theory of General Relativity mathematically at the age of 27. After graduating from KAIST, Oh earned his master’s and doctorate degrees from Princeton University, completed his post-doctoral fellow at UC Berkeley, and is now immersing himself in research at KIAS.
Heui-Kwang Noh from the Department of Chemistry and Kang-Min Ahn from the School of Computing, who were selected to receive the presidential scholarship for science in 2014, both graduated from Gyeonggi Science High School. Noh was recognized for his outstanding academic capacity and was also chosen for the ‘GE Foundation Scholar-Leaders Program’ in 2015. The ‘GE Foundation Scholar-Leaders Program’, established in 1992 by the GE Foundation, aims at fostering talented students. This program is for post-secondary students who have both creativity and leadership. It selects five outstanding students and provides 3 million KRW per annum for a maximum of three years.
The grantees of this program have become influential people in various fields, including professors, executives, staff members of national/international firms, and researchers. And they are making a huge contribution to the development of engineering and science. Noh continues doing various activities, including the completion of his internship at ‘Harvard-MIT Biomedical Optics’ and the publication of a paper (3rd author) for the ACS Omega of American Chemical Society (ACS).
Ahn, a member of the Young Engineers Honor Society (YEHS) of the National Academy of Engineering of Korea, had an interest in startup businesses. In 2015, he founded DataStorm, a firm specializing in developing data solution, and merged with a cloud back-office, Jobis & Villains, in 2016. Ahn is continuing his business activities and this year he founded, and is successfully running, cocKorea.
“KAIST students whose alma mater are science academies form a top-tier group on campus and produce excellent performance,” said Associate Vice President for Admissions, Hayong Shin. “KAIST is making every effort to assist these students so that they can perform to the best of their ability.”

President Shin Shares His Biggest Challenges, Success, and New Mission
President Sung-Chul Shin talks on his biggest challenges, successes, and new mission in an interview with Times Higher Education on June 29. Followings are the full text of the interview.
▶ What are the unique challenges and advantages of being a university in the Asia-Pacific region?
Globalization is definitely the biggest challenge. KAIST has made strenuous institutional efforts to address this issue for decades. Globalization is not just about language issues, especially for an Asian university. There are still lingering cultural barriers. However, we are improving and seeing significant progress. Approximately 85 per cent of our classes are being lectured in English, and my ultimate goal is to make KAIST a bilingual campus for a more globalized environment.
Speaking of advantages, we can recruit top-quality students from neighboring countries.
▶ What role do universities have in creating social equality?
I strongly believe that education is an essential means of empowerment and social mobility. KAIST has diligently promoted policies to help ensure greater diversity, without discriminating against anyone’s talents on the basis of gender, race, or background.
We implement an equal opportunity admission system, with special consideration given to the underprivileged, geographically-excluded groups, North Korean refugees, and many other disadvantaged groups. We recruit five percent of our freshmen from these groups under our admission system annually.
As for the gender gap, our female student population is now over 25 per cent, and we expect in the very near future the ratio will increase up to 30 percent. However, female faculty ratio stands at around 10 per cent, so we will attempt to double the ratio soon.
In addition, we work to emphasize social responsibility to our students. They are a privileged group, so they should be responsible for giving back their knowledge and talents to society in diverse ways. I am very glad that many of our students engage in the social entrepreneurship programs we are running now. That will be fruitful for ensuring social equity as well as making society better.
▶ What is the most important issue affecting your university right now?
KAIST has now emerged as a world-class university and one of the most innovative universities in the Asia-Pacific region. However, building on our new reputation as a "world-leading" university remains a big challenge. As the first and top research university in Korea, KAIST has been the gateway to the advancement of science and technology and innovation.
We are now responsible for taking the lead in creating new knowledge that will make a global impact. This is the momentum we need to make another quantum leap to become the university which creates the most global value.
▶ There is a great pressure in Korea for young people to get into a “top” university. Is this pressure on school students too great?
Traditionally, going to a top school was deemed the ladder to success in life. We went through the economically tough times in which diverse groups of occupations had never existed before. As a result, competition between individuals was incredibly high to get into good school and good company.
It is true that such social pressure occupied thoughts of many young students and their parents. In effect, that was also the driving force for achieving Korea’s economic growth in a relatively short period of time. But things are changing now.
We are living in a complex global economic environment. The number of new occupations creates new knowledge and new types of jobs. Even more, this new era changed the conventional paradigm of jobs and success. Successful careers take collaboration, and one must seek whom to work with, where you fit, and what you will do and how you can reach your potential.
This change of perception has begun to transform the general definition of a successful life. The government and educational institutions are working to reflect new socio-economic trend to maximize students’ creativity and their own uniqueness in many educational institutions.
However, strong competition to get into a top university seems to be a universal problem - as is also the case for the Ivy League in the US and many other regions.
▶ South Korean universities have some of the closest links to industry. Is a lot of your job about building relationships with companies rather than focusing on educational issues?
The relationship with industry is increasingly significant, and collaboration is very important in Korea. It is a crucial source for securing students’ jobs. On top of that, we get research funding from companies and supply the pipeline of new inventions and innovation for them, in many case through collaboration projects. That could also be interpreted as our reputation of institutional performance through diverse evaluation indicators.
From the industry side, we are a very good supplier of high-caliber manpower. Therefore, a solid relationship with industry is key to the creation of added value of knowledge, as well as a critical steppingstone for technology commercialization.
Therefore, scaling up the organic relationship with industry is part of our education and research portfolio as well as part of my job as president.
▶ Do you think the main role of universities is to prepare graduates for the world of work?
The role of higher education is to educate the future generation and create new knowledge though research. The conventional concept of research and development (R&D) has expanded to R&DB, as it now includes business. Thus, the role of a university is also evolving. Universities should provide diverse opportunities for graduates to prepare them to contribute to society. That will be one of the ways to realize the social responsibility of a university.
▶ If someone else was taking over your role tomorrow, what’s the most useful advice you could give them?
When I took the office in March, I made up my mind to serve our students, faculty and staff with all my heart. I would say, inspire your people with leadership that they can emotionally connected with, if possible. In addition, I think only professionalism can make the best professionals.
▶ Who has inspired you during your career?
Dr. Kun-Mo Chung, former vice president of KAIST and former minister for science and technology, is my role model and mentor. He is an internationally renowned nuclear engineer and scholar, and successful technocrat who served as the minister for science and technology twice. He still teaches at KAIST in his eighties.
I admired his visionary leadership and his successful career as administrator as well as accomplished scholar. After graduating from Seoul National University, he went to Michigan State University. In his early thirties, he came back to Korea as a member of the United States Agency for International Development survey team to conduct the feasibility study for founding KAIST. He wrote the proposal in the Terman Report to the USAID that the establishment of KAIST would be necessary and useful for Korea. With $6 million dollar loan from the agency, he founded KAIST. He is the true innovator, I think.
▶ How do you use data to make sure your university is performing well? We are analyzing the diverse data released from international evaluation institutions such as THE data and Clarivate Analytics, as well as domestic institutions. Through the various indicators of data, we are keen to realize the global standard of our institution and advance our innovation competitiveness at a global level.

Face Recognition System 'K-Eye' Presented by KAIST
Artificial intelligence (AI) is one of the key emerging technologies. Global IT companies are competitively launching the newest technologies and competition is heating up more than ever. However, most AI technologies focus on software and their operating speeds are low, making them a poor fit for mobile devices. Therefore, many big companies are investing to develop semiconductor chips for running AI programs with low power requirements but at high speeds.
A research team led by Professor Hoi-Jun Yoo of the Department of Electrical Engineering has developed a semiconductor chip, CNNP (CNN Processor), that runs AI algorithms with ultra-low power, and K-Eye, a face recognition system using CNNP. The system was made in collaboration with a start-up company, UX Factory Co.
The K-Eye series consists of two types: a wearable type and a dongle type. The wearable type device can be used with a smartphone via Bluetooth, and it can operate for more than 24 hours with its internal battery. Users hanging K-Eye around their necks can conveniently check information about people by using their smartphone or smart watch, which connects K-Eye and allows users to access a database via their smart devices. A smartphone with K-EyeQ, the dongle type device, can recognize and share information about users at any time.
When recognizing that an authorized user is looking at its screen, the smartphone automatically turns on without a passcode, fingerprint, or iris authentication. Since it can distinguish whether an input face is coming from a saved photograph versus a real person, the smartphone cannot be tricked by the user’s photograph.
The K-Eye series carries other distinct features. It can detect a face at first and then recognize it, and it is possible to maintain “Always-on” status with low power consumption of less than 1mW. To accomplish this, the research team proposed two key technologies: an image sensor with “Always-on” face detection and the CNNP face recognition chip.
The first key technology, the “Always-on” image sensor, can determine if there is a face in its camera range. Then, it can capture frames and set the device to operate only when a face exists, reducing the standby power significantly. The face detection sensor combines analog and digital processing to reduce power consumption. With this approach, the analog processor, combined with the CMOS Image Sensor array, distinguishes the background area from the area likely to include a face, and the digital processor then detects the face only in the selected area. Hence, it becomes effective in terms of frame capture, face detection processing, and memory usage.
The second key technology, CNNP, achieved incredibly low power consumption by optimizing a convolutional neural network (CNN) in the areas of circuitry, architecture, and algorithms. First, the on-chip memory integrated in CNNP is specially designed to enable data to be read in a vertical direction as well as in a horizontal direction. Second, it has immense computational power with 1024 multipliers and accumulators operating in parallel and is capable of directly transferring the temporal results to each other without accessing to the external memory or on-chip communication network. Third, convolution calculations with a two-dimensional filter in the CNN algorithm are approximated into two sequential calculations of one-dimensional filters to achieve higher speeds and lower power consumption.
With these new technologies, CNNP achieved 97% high accuracy but consumed only 1/5000 power of the GPU. Face recognition can be performed with only 0.62mW of power consumption, and the chip can show higher performance than the GPU by using more power.
These chips were developed by Kyeongryeol Bong, a Ph. D. student under Professor Yoo and presented at the International Solid-State Circuit Conference (ISSCC) held in San Francisco in February. CNNP, which has the lowest reported power consumption in the world, has achieved a great deal of attention and has led to the development of the present K-Eye series for face recognition.
Professor Yoo said “AI - processors will lead the era of the Fourth Industrial Revolution. With the development of this AI chip, we expect Korea to take the lead in global AI technology.”
The research team and UX Factory Co. are preparing to commercialize the K-Eye series by the end of this year. According to a market researcher IDC, the market scale of the AI industry will grow from $127 billion last year to $165 billion in this year.

KAIST Intensive Science Camp for Middle-High School Students
The KAIST Global Institute of Talented Education (Director: Dong-Soo Kwon) invited around 90 middle and high school students for an advanced science intensive camp from January 22 to 24.
This camp targeted middle and high school students in community centers or child-care institutions. It aims to increase students’ interest in science and engineering, and assist them with their career paths through programs such as special lectures on science, advanced science projects, and career mentoring.
Participating students were divided into groups of seven or eight with a KAIST student as a mentor to conduct advanced science projects such as VR controller production and robot arm programming. The camp included exploring future career options and science and engineering college admission counselling.
Jiyoung Ryu, Research Professor for the KAIST Global Institute of Talented Education, said, “KAIST started the science and engineering career experience program in 2016 with the Ministry of Education and Korea Research Institute for Vocational Education and Training (KRIVET). So far, 6000 middle and high school students from around the country have participated. The camp is more meaningful since it educates students in social responsibility, in addition to the fields of science and engineering, both of which are missions and goals that KAIST strives for.” She continued to say, “We plan to continue to expand the program in the future.”

He will also share KAIST’s experiences in developing innovative initiatives to bring future-oriented and creative values into its educational and research programs.
On January 19, at the Global Future Council on Production, President Kang will speak about new technologies taking place in traditional production and distribution systems as introduced by the emergence of rapidly evolving technological advancements, and present KAIST’s endeavors to transform those changes into opportunities.
With an eminent group of scientists, including the Director of the US National Science Foundation France A. Córdova and the Editor-in-Chief Philip Campbell of Nature at the Global Science Outlook session, on January 20, President Kang will discuss key challenges for the global science agenda in the year ahead and examine the role of science in formulating public discussions and polices that will have great impact on society and the lives of people.
Currently, Professor Lee is the founding Co-Chair of the WEF’s Global Future Council, an interdisciplinary knowledge network dedicated to promoting innovative thinking on the future. On January 20, he will share his insights at an independent session entitled “World Changing Technology: Biotech and Neurotech,” briefing the audience on the current state of research, development, and commercialization in these fields, as well as explaining how they will contribute to coping with the Fourth Industrial Revolution.
Professor Lee said, “In recent years, we have seen the world become ever more complex, interconnected, and realigned as it is deeply affected by this unprecedented technological innovations, collectively driving the Fourth Industrial Revolution. One pillar of such innovation will take place in biotechnology and neuroscience, which will help us design solutions to many of global problems such as environment, pandemic diseases, aging, healthcare, and previously intractable illnesses.”
President Kang added, “This year’s Davos meeting will focus on the need to foster leadership at the national, regional, and global level to respond collectively with credible actions to issues of major concern for the sustainable and equitable growth, social inclusion, and human development. KAIST has always been a crucial player in these collaborative efforts, and I am happy to share our insights at the upcoming event.”
