KATT Tops at Appropriate Technology Competition
The KAIST Appropriate Technology Team (KATT) consisting of KAIST international students received gold and bronze awards at ‘the 9th Creative Design Competition for the Other 90%’. This year’s competition was hosted by the Ministry of Science, ICT and Future Planning at Seoul National University’s Global Convention Plaza on May 26. Undergraduate and graduate students nationwide formed 65 teams to participate in the competition.
The aim of the competition is to discover appropriate technology and sustainable design items to enhance quality of life for those with no or little access to science technology and its products around the world. This year’s competition categorized the designs into IT; water and energy; agriculture, hygiene, safety, and housing; and education. The teams were evaluated on their presentations and prototypes.
KATT produced alarm warning bracelets for people in developing countries and smart hybrid dryers for agricultural products. The alarm warning bracelets were designed for those living in tsunami risk zones; they use wireless communication technology to receive and transmit warning signals and can be produced for less than $4.
The smart hybrid dryers featured solar energy generation, aimed to help those with low income in subtropical, low-altitude regions with unstable climates, since there are currently no drying methods for agricultural products without direct exposure to sunlight. Therefore, the hybrid dryers allowed drying regardless of the weather, and thus increased the storage and distribution efficiency of agricultural products.
Ashar Alam from India who participated in developing the alarm warning bracelet said, “Through the appropriate technology club, I recognized problems in India that also affect neighboring countries such as Indonesia and Bangladesh. I wanted to actively use the science and technology knowledge I have accumulated in KAIST for the less fortunate.” He continued, “It was meaningful to develop the product using the respective talents of students from various countries with the spirit of developing appropriate technology.”

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.”

Key Interaction between the Circadian Clock and Cancer Identified
Professor Jae Kyoung Kim and his research team from the Department of Mathematical Sciences at KAIST found that the circadian clock drives changes in circadian rhythms of p53 which functions as a tumor suppressor. Using a differential equation, he applied a model-driven mathematical approach to learn the mechanism and role of p53.
Kim’s mathematical modeling has been validated by experimental studies conducted by a research team at Virginia Polytechnic Institute and State University (Virginia Tech) in the United State, which is led by Professor Carla Finkielstein. As a result, the researchers revealed that there is an important link existed between the circadian clock and cancer.
The findings of this research were published online in Proceedings of the National Academy of Sciences of the United States of the America (PNAS) on November 9, 2016.
The circadian clock in our brain controls behavioral and physiological processes within a period of 24 hours, including making us fall asleep at a certain time by triggering the release of the sleep hormone melatonin in our brain, for example, around 9 pm. The clock is also involved in various physiological processes such as cell division, movement, and development.
Disruptions caused by the mismatch of the circadian clock and real time due to chronic late night work, shiftwork, and other similar issues may lead to various diseases such as diabetes, cancer, and heart disease.
In 2014, when Kim met with Finkielstein, her research team succeeded in observing the changes of p53 over a period of 24 hours, but could not understand how the circadian clock controls the 24-hour rhythm of p53. It was difficult to determine p53’s mechanism since its cell regulation system is far more complex than other cells
To solve the problem, Kim set up a computer simulation using mathematical modeling and ran millions of simulations. Instead of the traditional method based on trial and error experiments, mathematical modeling allowed to save a great deal of time, cost, and manpower.
During this process, Kim proved that the biorhythm of p53 and Period2, an important protein in the circadian clock, are closely related. Cells usually consist of a cell nucleus and cytoplasm. While p53 exists in both nucleus and cytoplasm, it becomes more stable and its degradation slows down when it is in the nucleus.
Kim predicted that the Period2 protein, which plays a key role in the functioning of the circadian clock, could influence the nucleus entry of the p53 protein.
Kim’s predictions based on mathematical modeling have been validated by the Virginia team, thereby revealing a strong connection between the circadian clock and cancer.
Researchers said that this research will help explain the cause of different results from numerous anticancer drugs, which are used to normalize the level of p53, when they are administrated at different times and find the most effective dosing times for the drugs.
They also believe that this study will play an important role in identifying the cause of increasing cancer rates in shift-workers whose circadian clocks are unstable and will contribute to the development of more effective treatments for cancer.
Professor Kim said, “This is an exciting thing that my research can contribute to improving the healthy lives of nurses, police officers, firefighters, and the like, who work in shifts against their circadian rhythms. Taking these findings as an opportunity, I hope to see more active interchanges of ideas between biological sciences and mathematical science in Korea.”
This research has been jointly conducted between KAIST and Virginia Tech and supported by the T. J. Park Science Fellowship of POSCO, the National Science Foundation of the United States, and the Young Researcher Program of the National Research Foundation of Korea.

KAIST's Mathematician Reveals the Mechanism for Sustaining Biological Rhythms
Our bodies have a variety of biological clocks that follow rhythms or oscillations with periods ranging from seconds to days. For example, our hearts beat every second, and cells divide periodically. The circadian clock located in the hypothalamus generates twenty-four hour rhythms, timing our sleep and hormone release. How do these biological clocks or circuits generate and sustain the stable rhythms that are essential to life?
Jae Kyoung Kim, who is an assistant professor in the Department of Mathematical Sciences at KAIST, has predicted how these biological circuits generate rhythms and control their robustness, utilizing mathematical modeling based on differential equations and stochastic parameter sampling. Based on his prediction, using synthetic biology, a research team headed by Matthew Bennett of Rice University constructed a novel biological circuit that spans two genetically engineered strains of bacteria, one serves as an activator and the other as a repressor to regulate gene expression across multiple cell types, and found that the circuit generates surprisingly robust rhythms under various conditions.
The results of the research conducted in collaboration with KAIST (Korea Institute of Science and Technology), Rice University, and the University of Houston were published in Science (August 28, 2015 issue). The title of the paper is "Emergent Genetic Oscillations in a Synthetic Microbial Consortium" .
The top-down research approach, which focuses on identifying the components of biological circuits, limits our understanding of the mechanisms in which the circuits generate rhythms. Synthetic biology, a rapidly growing field at the interface of biosciences and engineering, however, uses a bottom-up approach.
Synthetic biologists can create complex circuits out of simpler components, and some of these new genetic circuits are capable of fluctuation to regulate gene production. In the same way that electrical engineers understand how an electrical circuit works as they construct batteries, resistors, and wires, synthetic biologists can understand better about biological circuits if they put them together using genes and proteins. However, due to the complexity of biological systems, both experiments and mathematical modeling need to be applied hand in hand to design these biological circuits and understand their function.
In this research, an interdisciplinary approach proved that a synthetic intercellular singling circuit generates robust rhythms to create a cooperative microbial system. Specifically, Kim's mathematical analysis suggested, and experiments confirmed, that the presence of negative feedback loops in addition to a core transcriptional negative feedback loop can explain the robustness of rhythms in this system. This result provides important clues about the fundamental mechanism of robust rhythm generation in biological systems.
Furthermore, rather than constructing the entire circuit inside a single bacterial strain, the circuit was split among two strains of Escherichia coli bacterium. When the strains were grown together, the bacteria exchanged information, completing the circuit. Thus, this research also shows how, by regulating individual cells within the system, complex biological systems can be controlled, which in turn influences each other (e.g., the gut microbiome in humans).
