<The winning team of the P4G Innovation Sprint poses with the Crown Prince of Denmark (sixth from the left in the first row) and President Shin (fifth from the left in the first row) during the awarding ceremony.>
Team Circos from KAIST and Denmark made a new sustainable business model for Hempel, a global coating supplier group in Denmark, and won the first prize at the P4G (the Partnership for Green Growth and Global Goals) Innovation Sprint held at KAIST’s Seoul campus on May 22. The six-member team was awarded one million KRW in prize money by the Crown Prince of Denmark. Two of winning team members have the privilege of traveling to visit Hempel in Denmark.
The winning team thought outside the box, inspired by box wine which reduced the sales price from traditional bottled wine. Six teams made up of members from different academic disciplines spent two nights and three days brainstorming ways to resolve the challenges of corporations such as Velux and Hempel from Denmark and SK from Korea.
The P4G Innovation Sprint is one of the events co-hosted by KAIST and Technological University of Denmark in celebration of the 60th anniversary of diplomatic relations establishment between Denmark and Korea and the 8th anniversary of the Green Growth Alliance between the two countries. The Crown Prince Couple also made a royal visit to Korea in honor of the 60th anniversary celebration and Green Growth Alliance between the two countries.
This Innovation Sprint aimed to develop young academics’ perspectives, skills, and talents for the next generation to better research the Sustainable Development Goals set by UN.
Three teams made their final five-minute pitches before the Crown Prince and President Sung-Chul
Shin and responded to questions from the four-member jury.
The Crown Prince of Denmark and President Shin both agreed that the collaborative and convergent ideas will address global problems.
The Crown Prince stressed in his congratulatory remarks the importance of partnership in this polarizing world to achieve sustainable improvements saying, “Partnerships are only possible to sustain through collaboration and hard work while staying curious, creative, and critical. " He also shared the special relationship with KAIST. His father-in-law Professor John Donaldson used to be a visiting professor of applied mathmatics at KAIST back in 2003.
President Shin added, “Collaboration across boundaries is most critical for responding to these issues. In that sense, this P4G Innovation Sprint is a shining example for demonstrating the collaborative efforts between teammates from diverse disciplines. When we work together and build convergent ideas, we will be more innovative and go further.”
<Winning team member Nicolai Thorball from DTU pitches at the final in the presence of the Crown Prince of Denmark and KAIST President Shin.>
“The canned packaging in the paint industry results in 40 times more carbon emission in the course of production. However, when using aluminum packaging which is recyclable, the waste amount will be cut dramatically,” pitched Nicolai Thorball from DTU on exchange at Seoul National University. Nicolai, whose major is environmental engineering, is one of two Danish students including Thomsen Xandra Flyvbjerg from the University of Southern Denmark. Flyvbjergy, majoring in business, is now on exchange at Sungkynkwan University.
“I am very glad to have the chance to understand the concept of the circular economy and green growth at the sprint. It was also very challenging to make ideation from so many ideas brainstormed,” said Dong-Eun Lee, a KAIST undergraduate from the Department of Biological Sciences. He said that he learned a lot from his two other teammates who are from the Program of Green Business & Policy at KAIST College of Business, Jae-Hee Park and Kyung-Hyun Kim. Juho Park majoring in mechanical engineering at KAIST was one of the team.
Circos’ solution for a sustainable model received acclaim from the jury members. DTU Senior Vice President Marianne Thellerson, one of jurors, claimed their model has very high market feasibility, saying, “Their idea could be commercialized right now into the market.” Professor Hee-Kyung Park from KAIST who helped participants’ ideation as one of four mentors said, “The winning team perfectly met all the components of the evaluation criteria, Solution, Acceleration, and Pitch.”
At this sprint, 10 students from Denmark and 29 KAIST students were divided into 6 teams and given the challenges of three companies. The Danish window facility company Velux presented its future glass window system and the paint company Hempel their circular economic new business model. SK challenged the students to help it become a global clean energy solution company. The event was based on a hacker blueprint that found the optimal solution to the topics proposed.

Engineered Microbial Production of Grape Flavoring
(Image 1: Engineered bacteria that produce grape flavoring.)
Researchers report a microbial method for producing an artificial grape flavor. Methyl anthranilate (MANT) is a common grape flavoring and odorant compound currently produced through a petroleum-based process that uses large volumes of toxic acid catalysts.
Professor Sang-Yup Lee’s team at the Department of Chemical and Biomolecular Engineering demonstrated production of MANT, a naturally occurring compound, via engineered bacteria. The authors engineered strains of Escherichia coli and Corynebacetrium glutamicum to produce MANT through a plant-based engineered metabolic pathway.
The authors tuned the bacterial metabolic pathway by optimizing the levels of AAMT1, the key enzyme in the process. To maximize production of MANT, the authors tested six strategies, including increasing the supply of a precursor compound and enhancing the availability of a co-substrate. The most productive strategy proved to be a two-phase extractive culture, in which MANT was extracted into a solvent. This strategy produced MANT on the scale of 4.47 to 5.74 grams per liter, a significant amount, considering that engineered microbes produce most natural products at a scale of milligrams or micrograms per liter.
According to the authors, the results suggest that MANT and other related molecules produced through industrial processes can be produced at scale by engineered microbes in a manner that would allow them to be marketed as natural one, instead of artificial one.
This study, featured at the Proceeding of the National Academy of Sciences of the USA on May 13, was supported by the Technology Development Program to Solve Climate Changes on Systems Metabolic Engineering for Biorefineries from the Ministry of Science and ICT.

Blue-enriched White Light to Wake You Up in the Morning
(from left: Professor Hyun Jung Chung, Professor Hyeon-Jeong Suk, Taesu Kim and Professor Kyungah Choi)
Here is a good news for those of who have difficulty with morning alertness. A KAIST research team proposed that a blue-enriched LED light can effectively help people overcome morning drowsiness. This study will provide the basis for major changes in future lighting strategies and thereby help create better indoor environments.
Considerable research has been devoted to unmasking circadian rhythms. The 2017 Nobel Prize in Physiology or Medicine went to Jeffrey C. Hall, Michael Rosbash, and Michael W. Young for unveiling the molecular mechanisms that control circadian rhythms. In particular, the relationship between light and its physiological effects has been investigated since the discovery of a novel, third type of photoreceptor in the human retina in the early 2000s. Rods and cones regulate visual effects, while the third type, photosensitive retinal ganglion cells, regulate a large variety of biological and behavioral processes including melatonin and cortisol secretion, alertness, and functional magnetic resonance imaging (fMRI).
Initial studies on light sources have shown that blue monochromatic, fully saturated lights are effective for stimulating physiological responses, but the relative effectiveness of commercially available white light sources is less well understood. Moreover, the research was more focused on the negative effects of blue light; for instance, when people are exposed to blue light at night, they have trouble achieving deep sleep because the light restrains melatonin secretion.
However, Professor Hyeon-Jeong Suk and Professor Kyungah Choi from the Department of Industrial Design and their team argue that the effects of blue-enriched morning light on physiological responses are time dependent, and that it has positive effects on melatonin levels and the subjective perception of alertness, mood, and visual comfort compared with warm white light.
The team conducted an experiment with 15 university students. They investigated whether an hour of morning light exposure with different chromaticity would affect their physiological and subjective responses differently. The decline of melatonin levels was significantly greater after the exposure to blue-enriched white light in comparison with warm white light.
Professor Suk said, “Light takes a huge part of our lives since we spend most of our time indoors. Light is one of the most powerful tools to affect changes in how we perceive and experience the environment around us.”
Professor Choi added, “When we investigate all of the psychological and physiological effects of light, we see there is much more to light than just efficient quantities. I believe that human-centric lighting strategies could be applied to a variety of environments, including residential areas, learning environments, and working spaces to improve our everyday lives.”
This research was collaborated with Professor Hyun Jung Chung from the Graduate School of Nanoscience and Technology and was published in Scientific Reports (10.1038/s41598-018-36791-5) on January 23, 2019.

KAIST Develops Analog Memristive Synapses for Neuromorphic Chips
(Professor Sung-Yool Choi from the School of Electrical Engineering)
A KAIST research team developed a technology that makes a transition of the operation mode of flexible memristors to synaptic analog switching by reducing the size of the formed filament. Through this technology, memristors can extend their role to memristive synapses for neuromorphic chips, which will lead to developing soft neuromorphic intelligent systems.
Brain-inspired neuromorphic chips have been gaining a great deal of attention for reducing the power consumption and integrating data processing, compared to conventional semiconductor chips. Similarly, memristors are known to be the most suitable candidate for making a crossbar array which is the most efficient architecture for realizing hardware-based artificial neural network (ANN) inside a neuromorphic chip.
A hardware-based ANN consists of a neuron circuit and synapse elements, the connecting pieces. In the neuromorphic system, the synaptic weight, which represents the connection strength between neurons, should be stored and updated as the type of analog data at each synapse.
However, most memristors have digital characteristics suitable for nonvolatile memory. These characteristics put a limitation on the analog operation of the memristors, which makes it difficult to apply them to synaptic devices.
Professor Sung-Yool Choi from the School of Electrical Engineering and his team fabricated a flexible polymer memristor on a plastic substrate, and found that changing the size of the conductive metal filaments formed inside the device on the scale of metal atoms can make a transition of the memristor behavior from digital to analog.
Using this phenomenon, the team developed flexible memristor-based electronic synapses, which can continuously and linearly update synaptic weight, and operate under mechanical deformations such as bending.
The team confirmed that the ANN based on these memristor synapses can effectively classify person’s facial images even when they were damaged. This research demonstrated the possibility of a neuromorphic chip that can efficiently recognize faces, numbers, and objects.
Professor Choi said, “We found the principles underlying the transition from digital to analog operation of the memristors. I believe that this research paves the way for applying various memristors to either digital memory or electronic synapses, and will accelerate the development of a high-performing neuromorphic chip.”
In a joint research project with Professor Sung Gap Im (KAIST) and Professor V. P. Dravid (Northwestern University), this study was led by Dr. Byung Chul Jang (Samsung Electronics), Dr. Sungkyu Kim (Northwestern University) and Dr. Sang Yoon Yang (KAIST), and was published online in Nano Letters (10.1021/acs.nanolett.8b04023) on January 4, 2019.
