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.”

Innovative Nanosensor for Disease Diagnosis
(Figure 1. Sensing Device)
(Figure 2. Protein templating route)
Breath pattern recognition is a futuristic diagnostic platform. Simple characterizing target gas concentrations of human exhaled breath will lead to diagnose of the disease as well as physical condition.
A research group under Prof. Il-Doo Kim in the Department of Materials Science has developed diagnostic sensors using protein-encapsulated nanocatalysts, which can diagnose certain diseases by analyzing human exhaled breath. This technology enables early monitoring of various diseases through pattern recognition of biomarker gases related to diseases in human exhalation.
The protein-templated catalyst synthesis route is very simple and versatile for producing not only a single component of catalytic nanoparticles, but also diverse heterogeneous intermetallic catalysts with sizes less than 3 nm. The research team has developed ever more sensitive and selective chemiresistive sensors that can potentially diagnose specific diseases by analyzing exhaled breath gases.
The results of this study, which were contributed by Dr. Sang-Joon Kim and Dr. Seon-Jin Choi as first authors were selected as the cover-featured article in the July issue of 'Accounts of Chemical Research,' an international journal of the American Chemical Society.
In human breath, diverse components are found including water vapor, hydrogen, acetone, toluene, ammonia, hydrogen sulfide, and carbon monoxide, which are more excessively exhaled from patients. Some of these components are closely related to diseases such as asthma, lung cancer, type 1 diabetes mellitus, and halitosis.
Breath analysis for disease diagnosis started from capturing exhaled breaths in a Tedlar bag and subsequently the captured breath gases were injected into a miniaturized sensor system, similar to an alcohol detector. It is possible to analyze exhaled breath very rapidly with a simple analyzing process. The breath analysis can detect trace changes in exhaled breath components, which contribute to early diagnosis of diseases.
However, technological advances are needed to accurately analyze gases in the breath, which occur at very low levels, from 1 ppb to 1 ppm. In particular, it has been a critical challenge for chemiresistive type chemical sensors to selectively detect specific biomarkers in thousands of interfering gases including humid vapor.
Conventionally, noble metallic catalysts such as platinum and palladium have been functionalized onto metal oxide sensing layers. However, the gas sensitivity was not enough to detect ppb-levels of biomarker species in exhaled breath.
To overcome the current limitations, the research team utilized nanoscale protein (apoferritin) in animals as sacrificial templates. The protein templates possess hollow nanocages at the core site and various alloy catalytic nanoparticles can be encapsulated inside the protein nanocages.
The protein nanocages are advantageous because a nearly unlimited number of material compositions in the periodic table can be assembled for the synthesis of heterogeneous catalytic nanoparticles. In addition, intermetallic nanocatalysts with a controlled atomic ratio of two different elements can be achieved using the protein nanocages, which is an innovative strategy for finding new types of catalysts. For example, highly efficient platinum-based catalysts can be synthesized, such as platinum-palladium (PtPd), platinum-nickel (PtNi), platinum-ruthenium (PtRu), and platinum-yttrium (PtY).
The research team developed outstanding sensing layers consisting of metal oxide nanofibers functionalized by the heterogeneous catalysts with large and highly-porous surface areas, which are especially optimized for selective detection of specific biomarkers. The biomarker sensing performance was improved approximately 3~4-fold as compared to the conventional single component of platinum and palladium catalysts-loaded nanofiber sensors. In particular, 100-fold resistance transitions toward acetone (1 ppm) and hydrogen sulfide (1 ppm) were observed in exhaled breath sensors using the heterogeneous nanocatalysts, which is the best performance ever reported in literature.
The research team developed a disease diagnosis platform that recognizes individual breathing patterns by using a multiple sensor array system with diverse sensing layers and heterogeneous catalysts, so that the people can easily identify health abnormalities. Using a 16-sensor array system, physical conditions can be continuously monitored by analyzing concentration changes of biomarkers in exhaled breath gases.
Prof. Kim said, “New types of heterogeneous nanocatalysts were synthesized using protein templates with sizes around 2 nm and functionalized on various metal oxide nanofiber sensing layers. The established sensing libraries can detect biomarker species with high sensitivity and selectivity.” He added, “the new and innovative breath gas analysis platform will be very helpful for reducing medical expenditures and continuous monitoring of physical conditions”
Patents related to this technology were licensed to two companies in March and June this year.

KAIST is stepping up its initiative for building global competitiveness. The Embassy Day hosted on June 23 will be a stepping stone to diversify its channels for promoting the global presence of KAIST. KAIST invited the foreign diplomatic corps from Seoul to share their successful journey to emerge as the world-class university. The event featured KAIST’s research highlights, academic experiences, and global environment through presentations by faculty and students.
KAIST President Sung-Chul Shin said in his welcoming speech that he hopes for brains from around the world to come to KAIST and believes this event will serve as an opportunity to spread the global reputation of KAIST more widely. President Shin, who took office in March, ambitiously hosted this event for the first time, saying, “We didn’t expect this big of a response from the diplomats. The presence of this leading group of diplomats reflects how KAIST’s reputation has blossomed.”
Nearly 100 diplomats from 65 countries attended the event held at the Grand Hyatt Seoul. Among the participants were ambassadors from 33 countries including Australian Amb. James Choi, Canadian Amb. Eric Walsh, and German Amb. Stephan Auer, reflecting the growing interest in the advancements in science and technology education and innovation in KAIST.
The entire leadership team of KAIST turned out for the event including Provost O-Ok Park, Associate Vice President of the International Office Jay Hyung Lee, and Dean of Admissions Hayong Shin to provide an update on KAIST activities as well as admission policies, and make a new network with the foreign envoys.
At the event, KAIST presented some of its latest research highlights that are gaining international acclaim. Professor Jun-ho Oh, director at the Humanoid Robot Research Center talked on the short history of the development of the KAIST humanoid robot, HUBO, which won the DARPA Robotics Challenge (DRC) in 2015. Distinguished Professor Sang-Yup Lee, dean of the KAIST Institute, which is the center of multidisciplinary research projects in KAIST, made a presentation on advances in metabolic engineering. In addition, Professor David Helfman of the Department of Biological Science shared his research on breast cancer and metastasis.
Foreign students and faculty shared their experiences on becoming part of the KAIST community during the testimonial session. In particular, the story of Professor Jean-Charles Bazin of the Graduate School of Culture Technology was quite moving. Originally from France, Professor Bazin talked about his unique career path, starting as an exchange student at KAIST before settling down as a faculty member here. He cited the high caliber group of faculty as one of the reasons he completed his Ph.D. at KAIST. “Most of the faculty members are from top institutions in the US, Europe, and around the world, so they have very resourceful contacts with distinguished researchers and scholars abroad. That helped me make up my mind to choose KAIST,” he said.
Currently, 179 foreign faculty and researchers from over 31 countries, representing 8.7% of the total faculty, are working at KAIST. Also, 710 foreign students from 86 countries, representing about 8% of the total students, are now studying at KAIST.

Total Synthesis of Flueggenine C via an Accelerated Intermolecular Rauhut-Currier Reaction
The first total synthesis of dimeric securinega alkaloid (-)-flueggenine C was completed via an accelerated intermolecular Rauhut–Currier (RC) reaction. The research team led by Professor Sunkyu Han in the Department of Chemistry succeeded in synthesizing the natural product by reinventing the conventional RC reaction.
The total synthesis of natural products refers to the process of synthesizing secondary metabolites isolated from living organisms in the laboratory through a series of chemical reactions. Each stage of chemical reaction needs to be successful to produce the final target molecule, and thus the process requires high levels of patience and creativity. For that reason, the researchers working on natural products total synthesis are often called “molecular artists”.
Despite numerous reports on the total synthesis of monomeric securinegas, the synthesis of dimeric securinegas, whose monomeric units are connected by a putative enzymatic RC reaction, has not been reported to date.
The team used a Rauhut-Currier (RC) reaction, a carboncarbon bond forming a reaction between two Michael acceptors first reported by Rauhut and Currier in 1963, to successfully synthesize a dimeric natural product, flueggenine C. This new work featured the first application of an intermolecular RC reaction in total synthesis.
The conventional intermolecular RC reaction was driven non-selectively by a toxic nucleophilic catalyst at a high temperature of over 150°C and a highly concentrated reaction mixture, and thus has never been applied to natural products total synthesis. To overcome this long-standing problem, the research team placed a nucleophilic moiety at the γ-position of the enone derivative. As a result, the RC reaction could be induced by the simple addition of a base at ambient temperature and dilute solution, without the need of a nucleophilic catalyst. Using this newly discovered reactivity, the team successfully synthesized the natural product (-)-flueggenine C from commercially available amino acid derivative in 12 steps.
Professor Han said, “Our key finding regarding the remarkably improved reactivity and selectivity of the intermolecular RC reaction will serve as a significant stepping stone in allowing this reaction to be considered a practical and reliable chemical tool with broad applicability in natural products, pharmaceuticals, and materials syntheses. ”
This research was led by Ph.D. candidate Sangbin Jeon and was published in The Journal of the American Chemical Society (JACS) on May 10. This research was funded by KAIST start-up funds, HRHR (High-Risk High-Return), RED&B (Research, Education, Development & Business) projects, the National Research Foundation of Korea, and the Institute for Basic Science.

KAIST Class of '77 Celebrates 40-Year Reunion
The class of 1977 reunited on April 20 at the College of Business in Seoul campus, which was once the main campus when they were students 40 years ago. Now leaders of Korea in the sectors of industry, academia, and research, the class of ‘77 held a homecoming event in celebration of the 40th anniversary of their graduation.
The class of ’77 includes KAIST President Sung-Chul Shin and the Minister of Science, ICT and Future Planning Yanghee Choi. More than 100 graduates and 20 professors gathered at the homecoming event. Many of them were former ministers of science and technology, presidents of universities, heads of research institutes, and top managers from leading corporations such as Samsung Electronics and SK Telecom in Korea.
At the event, Professor Dong-Hoon Choi at Hangyang University, representing alumni Yoon-Mo Koo, Oh-Hyun Kwon, Dae-Young Kim, Yoo-Hyun Moon, Nam-Ho Paik, Ki Hwang Baek, Sung-Chul Shin, Mann-Ho Lee, and Sang-Bum Lee, donated a scholarship of 100 million KRW. Professor Choi said that, “This may not be a large sum of money, but we raised it with grateful hearts for the country and for KAIST. I hope this scholarship will become a small seed to raise bigger fruit.”
President Shin reminisced that, “The achievements made at KAIST during the last half century were only possible due to the dreams, visions, and innovative ideas of those who established KAIST, and the passion for research, education, and learning of our former professors and students.”
President Shin continued, “KAIST was the light of hope in the early industrialization period in Korea half a century ago, and as alumnus president I will devote body and soul for KAIST to be the light of hope in the early stages of the Industry 4.0, and thus continue to be the light of hope for the future of Korea.”

Tactile Sensor for Robot Skin Advanced by KAIST Team
The joint research team of Professors Jung Kim and Inkyu Park from the Department of Mechanical Engineering developed a tactile sensor that can act as skin for robots using silicon and carbon materials. This technology produced a sensor that can absorb shock and distinguish various forms of touch, and it is hoped to be used as robot skin in the future.
Skin serves an important role as the largest organ of the human body. As well as protecting major organs from external shock, skin also measures and distinguishes delicate tactile information and transfer it to the nervous system.
Current robotic sensory technology allows robots to have visual and auditory systems at nearly similar levels to human capacity, but there are limitations in tactile sensors that can detect changes in the environment throughout the body. To apply skin with similar functions as humans to robots, it is essential to develop skin sensor technology with high flexibility and high shock absorption. Another limitation for developing robot skin was connecting numerous sensors all over the body using electric wiring.
To overcome this problem, the research team combined silicon and carbon nanotubes (CNT) to produce a composite, which was then used in combination with a medical imaging technique called electrical impedance tomography (EIT). This led to technology that can distinguish various forms of force over a large area without electrical wiring.
The sensing material can distinguish the location and the size of various forms by touch, and thus can be applied to robot skin that can absorb shock as well as serves as a 3D computer interface and tactile sensor. It can withstand strong force such as a hammer strike, and can be re-used even after partial damage to the sensor by filling and hardening the damaged region with composite. Further, the sensor can be made by filling a 3D shape frame with silicon-nanotube composite. Using this technology, new forms of computer interaces can be developed with both curbed and flat surfaces.
This research was conducted through a collaboration between Professor Park, an expert in nanostructures and sensors, and Professor Kim, an expert in bio-robotics. Hence, the technology is likely to be applied in real products.
Professor Kim said, “Flexible tactile sensors can not only be directly adhered to the body, but they also provides information on modified states in multiple dimensions”. He continued, “This technology will contribute to the soft robot industry in the areas of robot skin and the field of wearable medical appliances.”
Professor Park said, “This technology implemented a next-generation user interface through the integration of functional nano-composite material and computer tomography.”
This research was published in Scientific Reports, a sister journal of Nature, online on January 25. This research was conducted as joint research by first author Hyo-Sang Lee, as well as Donguk Kwon and Ji-seung Cho, and was funded by the Ministry of Science, ICT and Future Planning.

KAIST's Future Strategy Graduate School Holds Its 100th Public Forum
The Graduate School of Future Strategy at KAIST has hosted regularly a public forum on Fridays at the Korea Telecom building in Seoul, to offer an open platform for policy discussions and exchange ideas since its establishment in 2012.
This Friday’s forum on March 17, 2017 will mark the hundredth of its kind.
The forum has served as a weekly meeting at which experts and citizens from various professional backgrounds gather together and share their views and insights on strategies and policies to help Korea advance toward a better future. As a result, the forum has implemented its role as a catalyst for “collected intellectualism.”
To date, over 200 participants have engaged in discussions and put forward suggestions on such issues as future strategies, a smart defense system, mid- and long-term national development, artificial intelligence (AI), the Internet of Things, augmented reality, robotics, and future automotive technology. The forum has also taken the lead in identifying issues that will become important to national progress in the era of the Fourth Industrial Revolution.
Among the notable topics discussed so far, the aftermath of the Al-embedded video game of Go, AlphpaGo’s match against a human player, which took place in March last year in Korea, attracted a great deal of attention from the public.
The Friday’s forum will discuss ways to unify the divisive public views over the recent political issue of the presidential impeachment and explore strategies to promote mutual growth and solidity. The event will be conducted in Korean only, and also be aired live via the Africa Web Television and Facebook for online participation.
Ideas proposed and suggested during discussions are compiled and published annually as a book entitled “The National Future Strategy for the Republic of Korea.”
Professor Kwang Hyung Lee of the Future Strategy Graduate School said, “When we first envisioned this setting for these discussions, no one at our school really thought that we would host the forum 100 times. It has lasted much longer than we could have imagined, and we hope that this will continue to remain relevant to society as a meaningful public venue to think about our nation’s future.”
