Professor Jae-Kyu Lee's Memoir "Knowledge and Beyond"
Professor Jae-Kyu Lee of KAIST’s College of Business has recently published a book called Knowledge and Beyond (available only in Korean). It deals with selected aspects of science and the world around us.
In Knowledge and Beyond, he expounds on his understanding of science, business, life, and religion. In part autobiographical, he describes his thirty-year career and his interaction with his past students who are now leading scientists and scholars in Korea, and offers some advice on how to better treasure life. Professor Lee also recounts his own life: his childhood, growing up and maturing with his mates, love at first sight of and his unconditional love towards his wife.
With respect to science, he talks about the origin of knowledge and ways to find solutions to questions that seem almost impossible to answer and offers a few aphorisms, such as: “studying is more like a marathon, not a boxing match;” “do not predict, but plan your future” and “learn by head in class, learn by heart in life.”
Knowledge and Beyond is a must read for those who have become exhausted by today’s competitive world, reminding readers of their life goals and paths.
Professor Lee said, “I wrote this book for the young to share the true meaning of life over plain knowledge. You can never find out the true meaning of life unless you combine simple and spiritual knowledge, and I hope this book helps in showing a way to achieve it.”
Professor Lee has taught at KAIST since 1985, and is currently the Dean of KAIST's Business College. He was formerly the Dean of KAIST College of Management, Director of KAIST EEWS (energy, environment, water, and sustainability) and the Vice Provost of the Singapore Management University’s School of Information Systems. He was also the President of The Korea Society of Management Information Systems and the President of Korea Intelligent Information System Society.

'Dr. M,' Mobile Healthcare Showroom Opened at KI
Portable and wearable computers have made the way we manage our health easier and potentially more effective. Researchers from six departments and one graduate school at KAIST collaborated and conducted a one-year project called the “Mobile Healthcare Innovation” to develop a mobile healthcare system. Their research results are on exhibit on campus at the “Dr. M Showroom” which was open on March 13, 2015.
Located on the second floor of the College of Information and Electrical Engineering building, the showroom displays the entirety of mobile healthcare system developed during 2014, from the collection of biological data through smart sensors to analyzing big data to provide customized healthcare models for patients.
Standing in for a mobile doctor, Dr. M is a networked medical service system provided through the Internet of Things (IoC), wearable electronics, smart home, and smart car. Under this care, people can monitor their health on a daily basis at any-time and place, helping them to lower the risk of serious health problems. Patients who have chronic diseases such as diabetes or cardiovascular illness can inform doctors of their health status in real time. Moreover, people living in remote regions can receive quality medical services without traveling long distances.
At the showroom, about 40 convergence technologies are displayed, including biological sensors, low-power communication devices, IoC technology, big data, disease analysis, and prediction technology, presenting how these technologies are connected and worked systematically. For example, all the data earned from biological sensors are analyzed to produce relevant user information. Once abnormalities are discovered, the results would be sent immediately to medical staff for treatment.
As part of Dr. M, KAIST has been implementing the establishment of a “Mobile Healthcare Campus,” distributing small, wearable wristbands to 100 students. The wristbands read students’ biological signals and send them to researchers for monitoring. In addition, KAIST plans to collaborate with local hospitals, nursing care centers, communications, and mobile healthcare service providers for the commercialization of Dr. M system.
Professor Hoi-Jun Yoo of the Electrical Engineering Department, who has led the Mobile Healthcare Innovation project said, “One of the great advantages Dr. M can offer is the capability to customize healthcare service based on individuals and ages. For individuals in their twenties, for example, healthcare services such as skincare and diet programs will be more relevant whereas blood pressure monitoring for patients in their fifties and early diagnosis for the recurrence of diseases for those in their seventies. If we define human history in terms of major technology advancements, the first big one was computation, communication for the second, and I think ubiquitous healthcare will be the third one. We will continue to develop Dr. M in collaboration with medical and research organizations.”
A total of 32 professors from the Departments of Electrical Engineering, Computer Science, Industrial and Systems Engineering, Industrial Design, Web Science, Knowledge Service Engineering, and the Information Security Graduate School participated in the Mobile Healthcare Innovation project.

KAIST Develops Ultrathin Polymer Insulators Key to Low-Power Soft Electronics
Using an initiated chemical vapor deposition technique, the research team created an ultrathin polymeric insulating layer essential in realizing transistors with flexibility and low power consumption. This advance is expected to accelerate the commercialization of wearable and soft electronics.
A group of researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed a high-performance ultrathin polymeric insulator for field-effect transistors (FETs). The researchers used vaporized monomers to form polymeric films grown conformally on various surfaces including plastics to produce a versatile insulator that meets a wide range of requirements for next-generation electronic devices. Their research results were published online in Nature Materials on March 9th, 2015.
FETs are an essential component for any modern electronic device used in our daily life from cell phones and computers, to flat-panel displays. Along with three electrodes (gate, source, and drain), FETs consist of an insulating layer and a semiconductor channel layer. The insulator in FETs plays an important role in controlling the conductance of the semiconductor channel and thus current flow within the translators. For reliable and low-power operation of FETs, electrically robust, ultrathin insulators are essential. Conventionally, such insulators are made of inorganic materials (e.g., oxides and nitrides) built on a hard surface such as silicon or glass due to their excellent insulating performance and reliability.
However, these insulators were difficult to implement into soft electronics due to their rigidity and high process temperature. In recent years, many researchers have studied polymers as promising insulating materials that are compatible with soft unconventional substrates and emerging semiconductor materials. The traditional technique employed in developing a polymer insulator, however, had the limitations of low surface coverage at ultra-low thickness, hindering FETs adopting polymeric insulators from operating at low voltage.
A KAIST research team led by Professor Sung Gap Im of the Chemical and Biomolecular Engineering Department and Professor Seunghyup Yoo and Professor Byung Jin Cho of the Electrical Engineering Department developed an insulating layer of organic polymers, “pV3D3,” that can be greatly scaled down, without losing its ideal insulating properties, to a thickness of less than 10 nanometers (nm) using the all-dry vapor-phase technique called the “initiated chemical vapor deposition (iCVD).”
The iCVD process allows gaseous monomers and initiators to react with each other in a low vacuum condition, and as a result, conformal polymeric films with excellent insulating properties are deposited on a substrate. Unlike the traditional technique, the surface-growing character of iCVD can overcome the problems associated with surface tension and produce highly uniform and pure ultrathin polymeric films over a large area with virtually no surface or substrate limitations. Furthermore, most iCVD polymers are created at room temperature, which lessens the strain exerted upon and damage done to the substrates.
With the pV3D3 insulator, the research team built low-power, high-performance FETs based on various semiconductor materials such as organics, graphene, and oxides, demonstrating the pV3D3 insulator’s wide range of material compatibility. They also manufactured a stick-on, removable electronic component using conventional packaging tape as a substrate. In collaboration with Professor Yong-Young Noh from Dongguk University in Korea, the team successfully developed a transistor array on a large-scale flexible substrate with the pV3D3 insulator.
Professor Im said, “The down-scalability and wide range of compatibility observed with iCVD-grown pV3D3 are unprecedented for polymeric insulators. Our iCVD pV3D3 polymeric films showed an insulating performance comparable to that of inorganic insulating layers, even when their thickness were scaled down to sub-10 nm. We expect our development will greatly benefit flexible or soft electronics, which will play a key role in the success of emerging electronic devices such as wearable computers.”
The title of the research paper is “Synthesis of ultrathin polymer insulating layers by initiated chemical vapor deposition for low-power soft electronics” (Digital Object Identifier (DOI) number is 10.1038/nmat4237).

System Approach Using Metabolite Structural Similarity Toward TOM Suggested
A Korean research team at KAIST suggests that a system approach using metabolite structural similarity helps to elucidate the mechanisms of action of traditional oriental medicine.
Traditional oriental medicine (TOM) has been practiced in Asian countries for centuries, and is gaining increasing popularity around the world. Despite its efficacy in various symptoms, TOM has been practiced without precise knowledge of its mechanisms of action. Use of TOM largely comes from empirical knowledge practiced over a long period of time. The fact that some of the compounds found in TOM have led to successful modern drugs such as artemisinin for malaria and taxol (Paclitaxel) for cancer has spurred modernization of TOM.
A research team led by Sang-Yup Lee at KAIST has focused on structural similarities between compounds in TOM and human metabolites to help explain TOM’s mechanisms of action. This systems approach using structural similarities assumes that compounds which are structurally similar to metabolites could affect relevant metabolic pathways and reactions by biosynthesizing structurally similar metabolites.
Structural similarity analysis has helped to identify mechanisms of action of TOM. This is described in a recent study entitled “A systems approach to traditional oriental medicine,” published online in Nature Biotechnology on March 6, 2015. In this study, the research team conducted structural comparisons of all the structurally known compounds in TOM and human metabolites on a large-scale. As a control, structures of all available approved drugs were also compared against human metabolites. This structural analysis provides two important results. First, the identification of metabolites structurally similar to TOM compounds helped to narrow down the candidate target pathways and reactions for the effects from TOM compounds. Second, it suggested that a greater fraction of all the structurally known TOM compounds appeared to be more similar to human metabolites than the approved drugs. This second finding indicates that TOM has a great potential to interact with diverse metabolic pathways with strong efficacy. This finding, in fact, shows that TOM compounds might be advantageous for the multitargeting required to cure complex diseases. “Once we have narrowed down candidate target pathways and reactions using this structural similarity approach, additional in silico tools will be necessary to characterize the mechanisms of action of many TOM compounds at a molecular level,” said Hyun Uk Kim, a research professor at KAIST.
TOM’s multicomponent, multitarget approach wherein multiple components show synergistic effects to treat symptoms is highly distinctive. The researchers investigated previously observed effects recorded since 2000 of a set of TOM compounds with known mechanisms of action. TOM compounds’ synergistic combinations largely consist of a major compound providing the intended efficacy to the target site and supporting compounds which maximize the efficacy of the major compound. In fact, such combination designs appear to mirror the Kun-Shin-Choa-Sa design principle of TOM.
That principle, Kun-Shin-Choa-Sa (君臣佐使 or Jun-Chen-Zuo-Shi in Chinese) literally means “king-minister-assistant-ambassador.” In ancient East Asian medicine, treating human diseases and taking good care of the human body are analogous to the politics of governing a nation. Just as good governance requires that a king be supported by ministers, assistants and/or ambassadors, treating diseases or good care of the body required the combined use of herbal medicines designed based on the concept of Kun-Shin-Choa-Sa. Here, the Kun (king or the major component) indicates the major medicine (or herb) conveying the major drug efficacy, and is supported by three different types of medicines: the Shin (minister or the complementary component) for enhancing and/or complementing the efficacy of the Kun, Choa (assistant or the neutralizing component) for reducing any side effects caused by the Kun and reducing the minor symptoms accompanying major symptom, and Sa (ambassador or the delivery/retaining component) which facilitated the delivery of the Kun to the target site, and retaining the Kun for prolonged availability in the cells.
The synergistic combinations of TOM compounds reported in the literature showed four different types of synergisms: complementary action (similar to Kun-Shin), neutralizing action (similar to Kun-Choa), facilitating action or pharmacokinetic potentiation (both similar to Kun-Choa or Kun-Sa). Additional structural analyses for these compounds with synergism show that they appeared to affect metabolism of amino acids, co-factors and vitamins as major targets.
Professor Sang Yup Lee remarks, “This study lays a foundation for the integration of traditional oriental medicine with modern drug discovery and development. The systems approach taken in this analysis will be used to elucidate mechanisms of action of unknown TOM compounds which will then be subjected to rigorous validation through clinical and in silico experiments.”

The Real Time Observation of the Birth of a Molecule
From right to left: Dr. Kyung-Hwan Kim, Professor Hyotcherl Lhee, and Jong-Gu Kim, a Ph.D. candidate
Professor Hyotcherl Lhee of the Department of Chemistry at KAIST and Japanese research teams jointly published their research results showing that they have succeeded in the direct observation of how atoms form a molecule in the online issue of Nature on February 19, 2015.
The researchers used water in which gold atoms ([Au(CN) 2- ]) are dissolved and fired X-ray pulses over the specimen in femtosecond timescales to study chemical reactions taking place among the gold atoms. They were able to examine in real time the instant process of how gold atoms bond together to become a molecule, to a trimer or tetramer state.
This direct viewing of the formation of a gold trimer complex ([Au(CN) 2- ] 3 ) will provide an opportunity to understand complex chemical and biological systems.
For details, please see the following press release that was distributed by the High Energy Accelerator Research Organization, KEK, in Japan:
Direct Observation of Bond Formations
February 18, 2015
A collaboration between researchers from KEK, the Institute for Basic Science (IBS), the Korea Advanced Institute of Science and Technology (KAIST), RIKEN, and the Japan Synchrotron Radiation Research Institute (JASRI) used the SACLA X-ray free electron laser (XFEL) facility for a real time visualization of the birth of a molecular that occurs via photoinduced formation of a chemical bonds. This achievement was published in the online version of the scientific journal “Nature” (published on 19 February 2015).
Direct “observation” of the bond making, through a chemical reaction, has been longstanding dream for chemists. However, the distance between atoms is very small, at about 100 picometer, and the bonding is completed very quickly, taking less than one picosecond (ps). Hence, previously, one could only imagine the bond formation between atoms while looking at the chemical reaction progressing in the test-tube.
In this study, the research group focused on the process of photoinduced bond formation between gold (Au) ions dissolved in water. In the ground state (S 0 state in Fig. 1) Au ions that are weakly bound to each other by an electron affinity and aligned in a bent geometry. Upon a photoexcitation, the S 0 state rapidly converts into an excited (S 1 state in Fig. 1) state where Au-Au covalent bonds are formed among Au ions aligned in a linear geometry. Subsequently, the S 1 state transforms to a triplet state (T 1 state in Fig. 1) in 1.6 ps while accompanying further contraction of Au-Au bonds by 0.1 Å. Later, the T 1 state of the trimer converts to a tetramer (tetramer state in Fig. 1) on nanosecond time scale. Finally, the Au ions returned to their original loosely interacting bent structure.
In this research, the direct observation of a very fast chemical reaction, induced by the photo-excitation, was succeeded (Fig. 2, 3). Therefore, this method is expected to be a fundamental technology for understanding the light energy conversion reaction. The research group is actively working to apply this method to the development of viable renewable energy resources, such as a photocatalysts for artificial photosynthesis using sunlight.
This research was supported by the X-ray Free Electron Laser Priority Strategy Program of the MEXT, PRESTO of the JST, and the the Innovative Areas "Artificial Photosynthesis (AnApple)" grant from the Japan Society for the Promotion of Science (JSPS).

KAIST Develops Subminiature, Power-Efficient Air Pollution Sensing Probe
Professor Inkyu Park and his research team from the Department of Mechanical Engineering at KAIST have developed a subminiature, power-efficient air-pollution sensing probe that can be applied to mobile devices. Their research findings were published online in the January 30th issue of Scientific Reports.
As air pollution has increased, people have taken greater interest in health care. The developed technology could allow people to measure independently the air pollution level of their surrounding environments.
Previous instruments used to measure air pollution levels were bulky and consumed a lot of power. They also often produced inaccurate results when measuring air pollution in which different toxic gases were mixed. These problems could not be resolved with existing semiconductor manufacturing process.
Using local temperature field control technology, Professor Park’s team succeeded in integrating multiple heterogeneous nanomaterials and fitting them onto a small, low-power electronic chip. This microheating sensor can heat microscale regions through local hydrothermal synthesis. Because it requires a miniscale amount of nanomaterials to manufacture, the sensor is most suitable for mobile devices.
Professor Park said, “Our research will contribute to the development of convergence technology in such field as air pollution sensing probes, biosensors, electronic devices, and displays.”
The team's research was supported by the Ministry of Education and the Ministry of Science, ICT and Future Planning, Republic of Korea.

The Number of KAIST Doctoral Graduates to Reach Over Ten Thousands
The ten-thousandth doctoral graduate received her degree in the commencement ceremony on February 13, 2015.
KAIST has contributed to the development of science, technology, and industry in Korea by fostering talents in advanced science and engineering.
Since its establishment forty-four years ago, more than ten-thousand KAIST alumni have received their doctorates. This year’s graduation ceremony took place on February 13, 2015, at the Sports Complex on campus, awarding the ten-thousandth doctoral degree.
Dr. Sun-Mi Cho of the Department of Biological Sciences received the ten-thousandth doctoral degree. A graduate of Jeon-Nam Science High School, Dr. Cho also received her Bachelor of Science degree from KAIST.
Dr. Cho wrote a dissertation entitled “GABA from reactive astrocytes impairs learning and memory in Alzheimer disease.” Her dissertation adviser was Professor Daesoo Kim of the Department of Biological Sciences.
Dr. Cho, who will be a post-doctorate researcher at the Biological Sciences Department, said, “It was my childhood dream to receive a doctorate from KAIST. I cannot believe that I’m the ten-thousandth doctoral graduate, for which I’m very grateful.” She continued, “I hope to become a neuroscientist where I can be of help to the sick.”
In 1978, KAIST only had two doctoral graduates, but since 1987 there have been more than one hundred graduates each year, two hundred since 1994, and four hundred since 2000. In 2015, 522 doctoral students graduated.
One of the first doctoral graduates, Dong-Yol Yang (class of 1978 in the Mechanical Engineering Department), became a professor at the same department of KAIST. Professor Yang expressed his thoughts on the news, “There was a trend in Korea to go overseas for Ph.D. degrees in the early 1970s, but it changed when KAIST began to select candidates for Master’s degrees in 1973 and Doctoral degrees in 1975. Talented Korean students came to KAIST laboratories, and its graduates were known for their knowledge and skills. Now, we see that the talent is coming from overseas.”
At the 2015 Commencement, KAIST conferred 522 Doctoral, 1,241 Master’s, and 915 Bachelor of Science (B.S.) degrees.
Since its inception in 1971, KAIST has granted 10,403 doctor's, 26,402 master's, and 51,412 bachelor's degrees.

Professor Kwang-Hyun Cho Recognzied by "Scientist of the Month" Award
Professor Kwang-Hyun Cho of KAIST’s Department of Bio and Brain Engineering received the “Scientist of the Month” award in February 2015 from the Ministry of Science, ICT, and Future Planning of the Republic of Korea and the National Research Foundation of Korea. The award was in recognition of Professor Cho’s contribution to the advanced technique of controlling the death of cancer cells based on systems biology, a convergence research in information technology (IT) and biotechnology.
Professor Cho has published around 140 articles in international journals, including 34 papers in renowned science journals such as Nature, Science, and Cell in the past three years. His work also includes systems biology textbooks and many entries in international academic encyclopaedia.
His field, systems biology, is a new biological research paradigm that identifies and controls the fundamental principles of organisms on a systems level.
A well-known tumour suppressor protein, p53, is known to suppress abnormal cell growth and promote apoptosis of can cells, and thus was a focus of research by many scientists, but its effect has been insignificant and brought many side effects. This was due to the complex function of p53 that controls various positive and negative feedbacks. Therefore, there was a limit to understanding the protein with the existing biological approach.
However, Professor Cho found the kinetic change and function of p53 via a systems biology approach. By applying IT technology to complex biological networks, he also identified the response to stress and the survival and death signal transduction pathways of cardiomyocytes and developed new control methods for cancer cells.
Professor Cho said, “This award served as a momentum to turn over a new leaf.” He added, “I hope convergence research such as my field will bring more innovative ideas on the boundaries of academia.”
