KAIST Robotic Art: Exhibit called "Artificial Brain, Robots Evolve"
It is not difficult to find the desire to create a Neoanthropinae in the history of mankind. Humans evolve through man-made extensions and live by self-training them. This is Seung Hyun Son’s description which encourages us to discuss the changes man-made humanoids would bring to our future lives. He depicts this in “Theory of Evolution: From mankind to humanoid” in the “Artificial Brain, Robots Evolve” exhibition in the KI Building, KAIST, from 21 November 2014 to 8 February 2015.
KAIST's Art and Design Committee (led by President Myung Seok Kim) is holding the third experimental art exhibition based on the integration of science and art. The previous exhibition themes were “See the Sky” in 2012 and “Life is Beautiful” in 2013. The exhibition is divided into five subtopics: Move, Feel, Think, Express, and Experiment in Imagination.
The exhibits are by 17 artists including Nam June Paik, Nancy Lang, and KAIST Professor Myung Seok Kim. The main exhibits include “Cloud Face,” by Seung Baek Shin and Yong Hoon Kim, that shows up as error on computer but can be seen by human eyes and “Brains in Vat," by Boo Rok Lee and Myung Chul Kim based on KAIST's robotic lab’s materials and motif. Also, “The May of My Life” by Professor Myung Seok Kim’s lab reminds us of the relationship between robot and human.
President Myung Seok Kim said, “The range of content in cultural art will inspire students’ imagination.” He continued, “I hope this exhibition will awaken both scientific ideas and artistic sense.”
The opening ceremony of the exhibition will be held from 14:00, 21 November. The “Artificial Brain, Robots Evolve” exhibition is hosted by the Daejeon Museum of Art and sponsored by National Museum of Modern and Contemporary Art and Soma Museum.

Clear Display Technology Under Sunlight Developed
The late Professor Seung-Man Yang
The last paper of the late Professor Seung-Man Yang, who was a past master of colloids and fluid mechanics
Practical patterning technology of the next generation optical materials, photonic crystals
The mineral opal does not possess any pigments, but it appears colorful to our eyes. This is because only a particular wavelength is reflected due to the regular nano-structure of its surface. The material that causes selective reflection of the light is called photonic crystals.
The deceased Professor Seung-Man Yang and his research team from KAIST’s Chemical and Biomolecular Engineering Department ha ve developed micro-pattern technology using photolithographic process. This can accelerate the commercialization of photonic crystals, which is hailed as the next generation optics material.
The research results were published in the April 16th edition of Advanced Materials, known as the most prestigious world-renowned journal in the field of materials science.
The newly developed photonic crystal micro-pattern could be used as a core material for the next generation reflective display that is clearly visible even under sunlight. Since it does not require a separate light source, a single charge is enough to last for several days.
Until now, many scientists have endeavored to make photonic crystals artificially, however, most were produced in a lump and therefore lacked efficiency. Also, the low mechanical stability of the formed structure prevented from commercialization.
In order to solve these problems, the research team has copied the nano-structure of opals.
Glass beads were arranged in the same nano-structure as the opal on top of the photoresist material undergoing photocuring by ultraviolet light. The glass beads were installed in the photoresist materials, and UV light was selectively exposed on micro regions. The remaining region was developed by photolithographic process to successfully produce photonic crystals in micro-patterns.
The co-author of the research, KAIST Chemical and Biomolecular Engineering Department’s Professor Sin-Hyeon Kim, said, “Combining the semiconductor process technology with photonic crystal pattern technology can secure the practical applications for photonic crystals.”He also predicted “This technology can be used as the key optical material that configures the next generation reflective color display device with very low power consumption.”
The late Professor Seung-Man Yang was a world-renowned expert in the field of colloids and fluid mechanics. Professor Yang published over 193 papers in international journals and continued his research until his passing in last September.
He received Du Pont Science and Technology Award in 2007, KAIST Person of the Year 2008, Gyeong-Am Academy Award in 2009, as well as the President’s Award of the Republic of Korea in March 2014. The researchers devoted the achievement of this year’s research to Professor Yang in his honor.
Research was conducted by KAIST Photonic-fluidic Integrated Devices Research Team, as a part of the Creative Research Program funded by the Ministry of Science, ICT and Future Planning, Republic of Korea.

Prof. Jiyun Lee receives the U.S. FAA Achievement Award
- Ensures the safe operation of aircraft by monitoring ionospheric changes caused by solar storms.
KAIST’s Aerospace Engineering Department’s Professor Jiyun Lee has received an award from the U.S. Federal Aviation Administration (FAA), in recognition of her work for developing a Global Positioning System (GPS) reinforcing system and improving Satellite Navigation technology.
A GPS reinforcing system provides real-time GPS location and integrity information within 1m ranges to enable the accurate and safe navigation of aircraft. However, when the sun reaches Solar Max, the amount of total electron increases rapidly in the ionosphere. This also increases the possibility of the position error of navigation using the GPS reinforcing system. In order to solve this problem, Professor Lee built an Ionosphere Danger model that monitors the changes in the ionosphere due to solar storm. The model has been implemented into original monitoring software that secures the safety of the GPS reinforcing system user. The research results were published in July 2012 in Radio Science, one of the most prestigious international journals in the field of geophysical studies.
The FAA Technical Center successfully verified Professor Lee’s software and the software is currently being distributed and used by major institutions around the globe, including Eurocontrol. It is expected that the software will be standardized after consultations with international organizations in the recent future.
Professor Lee said, “Satellite navigation is the core of future navigation technology. Since its utilization has been extended to aviation, marine, transportation, telecommunications, finance and other major national infrastructures, it is crucial to ensure the performance and reliability of the system … In the future, cooperation between nations will help to develop the worldwide service of the GPS reinforcing system.”

Novel material that prevents health decline with age found
Professor Kim Dae Soo (Department of Biological Science), his research team, the Choong Nam University Medicine School, and various companies conducted collaborative research succeeded in developing a novel material that prevents health decline with age. The result was published in PLoS One Journal with the title “Beta-lapachone, a modulator of NAD metabolism, prevents health declines in aged mice”.
Longevity and health can be obtained with reducing consumption of food and aerobic exercise.
Professor Kim’s team focused on the fact that reduced consumption of food and aerobic exercise increase the coenzyme (NAD+) which suppresses the aging of cells. The research team discovered that by activating NQO1 enzyme with Beta-lapachone, the amount of NAD+ in the body increases even without reduction of food consumption or aerobic exercise.
Even consumption of Beta-lapachone by aging mice caused an improved on the brain and exercise ability of the mice. It is expected that commercialization of Beta-lapachone will be possible as it is a chemical that is commonly found in herbs used in both the orient and the oxidant.

The hereditary factor of autism revealed
Korean researchers have successfully investigated the causes and hereditary factors for autistic behavior and proposed a new treatment method with fewer side effects.
This research was jointly supported by the Ministry of Education, Science and Technology and the National Research Foundation as part of the Leading Researcher and Science Research Center Program
The research findings were publishing in the June edition of Nature magazine and will also be introduced in the July edition of Nature Reviews Drug Discovery, under the title ‘Autistic-like social behavior in Shank2-mutant mice improved by restoring NMDA receptor function’.
The research team found that lack of Shank2 genes in mice, which are responsible for the production of synapse proteins, caused autistic-like behavior. The results strongly suggested that the Shank2 gene was linked to autistic behavior and that Shank2 deficiency induced autistic behaviors.
Autism is a neural development disorder characterized by impaired social interaction, repetitive behavior, mental retardation, anxiety and hyperactivity. Around 100 million people worldwide display symptoms of autistic behavior. Recent studies conducted by the University of Washington revealed that 1 out of 3 young adults who display autistic behavior do not fit into the workplace or get accepted to college, a much higher rate than any other disorder. However, an effective cure has not yet been developed and current treatments are limited to reducing repetitive behavior.
The research team confirmed autistic-like social behavior in mice without the Shank2 genes and that the mice had decreased levels of neurotransmission in the NMDA receptor. The mice also showed damaged synaptic plasticity* in the hippocampus**.
* Plasticity: ability of the connectionbetween two neurons to change in strength in response to transmission of information
**Hippocampus: part of the brain responsible for short-term and long-term memory as well as spatial navigation.
The research team also found out that, to restore the function of the NMDA receptor, the passive stimulation of certain receptors, such as the mGLuR5, yielded better treatment results than the direct stimulation of the NMDA. This greatly reduces the side effects associated with the direct stimulation of receptors, resulting in a more effective treatment method.
This research successfully investigated the function of the Shank2 gene in the nerve tissue and showed how the reduced function of the NMDA receptor, due to the lack of the gene, resulted in autistic behavior. It also provided new possibilities for the treatment of autistic behavior and impaired social interaction

Genetic Cause of ADHD (Attention Deficit Hyperactivity Disorder) Found
The cooperative research team consisting research teams under Professor Kim Eun Joon and Professor Kang Chang Won of the department of Biological Sciences discovered that ADHD arises from the deficiency of GIT1 protein in the brain’s neural synapses.
ADHD (Attention Deficit Hyperactivity Disorder) is found in around 5% of children around the world and is a disorder where the child becomes unable to concentrate, show over the top responses, and display impulsive behavior.
The research team found that the difference between children with ADHD and those without it is one base in the GIT1 gene. The difference of a single base causes the underproduction of this protein, and those children with low levels of the protein had a higher probability to develop ADHD.
In addition, further evidence was provided when the research team conducted mice experiments. Those mice with low levels of GIT1 exhibited impulsive and exaggerated reactions like humans with ADHD, had learning disabilities, and produced abnormal brain waves. And upon injecting these mice with cure for ADHD, the symptoms of ADHD disappeared.
The impulsive behavior of ADHD children disappears as the child enters adulthood and a similar pattern was found in mice. A mice with low levels of GIT1 showed impulsive behaviors when 2 months old, but these behaviors disappeared as it got older to around 7 months old (equivalent to 20~30 years old for humans).
Professor Kim Eun Joon commented that there has to be equilibrium between mechanisms that excite the neurons and mechanisms that calm the neurons, but the lack of GIT1 leads to the decrease in the mechanisms that calm the neurons which causes the impulsive behavior of ADHD patients.
In addition, Professor Kang Chang Won commented that the results of the experiment has been receiving rave reviews and is being seen as the new method in the production of the cure for ADHD.
The result of the experiment was published in the online edition of Nature Medicine magazine.
