Open KAIST 2015
KAIST’s research environment and its most recent achievements were open to the public.
KAIST hosted “Open KAIST 2015” over two days from November 5-6, 2015 in which its 17 departments and three research centers were open to the public. The event is one of the largest events that KAIST holds, which permits such public viewings of its facilities. It is the eighth time it has taken place.
During this event, the departments and centers offered 64 programs including laboratory tours, research achievement exhibitions, department introductions, and special lectures.
The “Motion Capture System”of Professor Jun-Yong Noh’s lab (Graduate School of Culture Technology) drew particular attention.
The “Motion Capture System” expresses human and animal motion in three-dimensional (3D) space using infrared cameras and optic markers, which can then be applied to various industries such as movies, games, and animation. During the program, researchers themselves demonstrated the recording of the movement and its conversion into 3D characters.
Professor Yong-Hoon Cho’s laboratory introduced the scientific mechanism behind the Light Emitting Diode (LED) as well as its manufacturing process under the topic:“A to Z of LED Production.” The reserachers explained that how green LED is much more efficient compared to previous light sources and presented applications that how it is widely used in everyday life in smart phones, electronic displays, and other mobile gadgets.
Professor Jun-tani of the Department of Electronic and Electrical Engineering introduced “Humanoid Robot Nao’s Imitation of Human Motions.” Nao is an autonomous, programmable humanoid robot developed by a French robotics company based in Paris. Nao has an artificial neural circuit, which is the functional equivalent of a human brain, and can thus mimic the subject’s motions through learning.
In addition, Professor Hyo-Choong Bang (Department of Aerospace Engineering) in his lecture on “Unmanned Vehicle Research and Nano Satellites” and Professor Hyun Myung (Department of Civil and Environmental Engineering) on his lecture on “Future Civilization Robot System: the Jellyfish Elimination Robotic Swarm and the Wall-Climbing Drone” provided information on the progress of their respective research.
KAIST also displayed its most recent research achievements. A lecture on “Information Technology Convergence” offered a showroom for “Dr. M,” which is a mobile healthcare platform. Dr. M is a mobile healthcare system that collects and analyzes biosignals via a smart sensor attached to the human body that shows around 20 advanced technologies.
The Satellite Technology Research Center introduced the public to its “Get to Know Satellites” program on Korea’s first satellite “Our Star 1” in addition to showing the satellite assembly room and the satellite communication center.
Special lectures were also held for visitors. Professor Min-Hyuk Kim and Hye-Yeon Oh of the School of Computing talked about “Computer Graphics and Advanced Video Technology” and “Man and the Computer,” respectively, from the perspective of non-experts.
Another interesting feature was the “Wearable Computer Competition” in which college students held fashion shows with computers attached to their clothes.
Professor Jung Kwon Lee, the Dean of the College of Engineering, who led this event, said that “the Open KAIST, which is being held for the eighth time this year, is an excellent opportunity for the general public to experience KAIST’s research environment.” He hoped this could motivate young adults to widen their spectrum of scientific knowledge and raise affection for science.

A New Way to Look at MOFs
An international research team composed of researchers from KAIST (led by Professors Osamu Terasaki and Jeung Ku Kang at the Graduate School of Energy, Environment, Water and Sustainability) and other universities, including UC Berkeley, has recently published research results on the adsorption process of metal-organic frameworks (MOFs) in Nature (November 9, 2015).
MOFs are porous three-dimensional crystals with a high internal surface area, which have a wide range of applications involving adsorption such as hydrogen, methane, or carbon dioxide storage. In the paper entitled “Extra Adsorption and Adsorbate Superlattice Formation in Metal-organic Frameworks,” the research team described their observation of a very specific interpore interaction process in MOFs.

Using Light to Treat Alzheimer's Disease
Medical application of photoactive chemicals offers a promising therapeutic strategy for neurodegenerative diseases.
A research team jointly led by Professor Chan Beum Park of the Materials Science and Engineering Department at KAIST and Dr. Kwon Yu from the Bionano Center at the Korea Research Institute of Bioscience and Biotechnology (KRIBB) conducted research to suppress an abnormal assembly of beta-amyloids, a protein commonly found in the brain, by using photo-excited porphyrins.
Beta-amyloid plaques are known to cause Alzheimer's disease. This research finding suggests new ways to treat neurodegenerative illnesses including Alzheimer's disease. It was published online as the lead article in the September 21th issue of Angewandte Chemie. The title of the article is “Photo-excited Porphyrins as a Strong Suppressor of ß-Amyloid Aggregation and Synaptic Toxicity.”
Light-induced treatments using organic photosensitizers have advantages to managing the treatment in time and area. In the case of cancer treatments, doctors use photodynamic therapies where a patient is injected with an organic photosensitizer, and a light is shed on the patient’s lesion. However, such therapies had never been employed to treat neurodegenerative diseases.
Alzheimer's starts when a protein called beta-amyloid is created and deposited in a patient’s brain. The abnormally folded protein created this way harms the brain cells by inducing the degradation of brain functions, for example, dementia. If beta-amyloid creation can be suppressed at an early stage, the formation of amyloid deposits will stop. This could prevent Alzheimer’s disease or halt its progress.
The research team effectively prevented the buildup of beta-amyloids by using blue LED lights and a porphyrin inducer, which is a biocompatible organic compound. By absorbing light energy, a photosensitizer such as porphyrin reaches the excitation state. Active oxygen is created as the porphyrin returns to its ground state. The active oxygen oxidizes a beta-amyloid monomer, and by combining with it, disturbs its assembly.
The technique was tested on drosophilae or fruit flies, which were produced to model Alzheimer on invertebrates. The research showed that symptoms of Alzheimer's disease in the fruit flies such as damage on synapse and muscle, neuronal apoptosis, degradation in motility, and decreased longevity were alleviated. Treatments with light provide additional benefits: less medication is needed than other drug treatments, and there are fewer side effects. When developed, photodynamic therapy will be used widely for this reason.
Professor Park said, “This work has significance as it was the first case to use light and photosensitizers to stop deposits of beta-amyloids. We plan to carry the research further by testing compatibility with other organic and inorganic photosensitizers and by changing the subject of photodynamic therapy to vertebrate such as mice.”

Membrane
Scientists at KAIST have developed a new way of making fuel cell membranes using nanoscale fasteners, paving the way for lower-cost, higher-efficiency and more easily manufactured fuel cells.
The internal workings of fuel cells vary, but basically all types mix hydrogen and oxygen to produce a chemical reaction that delivers usable electricity and exhausts ordinary water as a by-product. One of the most efficient types is the proton exchange membrane (PEM) fuel cell, which operates at low enough temperatures to be used in homes and vehicles.
To generate electricity, PEM fuel cells rely on two chemical compartments separated by a permeable catalyst membrane. This membrane acts as an electrolyte; a negative electrode is bonded to one side of the membrane and a positive electrode is bonded to the other. The electrolyte membrane is often based on a polymer of perfluorosulfonic acid. Due to its high cost, however, a less expensive hydrocarbon-based electrolyte membrane has attracted interest in this technology sector.
Until now, the challenge in adopting such a hydrocarbon membrane has been that the interface between the electrode and hydrocarbon membrane is weak. This causes the membrane to delaminate relatively easily, falling apart and losing efficiency with use.
Professor Hee-Tak Kim of the Department of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST) and his research team have developed a new fastening system that bonds the two materials mechanically rather than chemically. This opens the way to the development of fuel cell membranes that are less expensive, easier to manufacture, stronger and more efficient.
The researchers achieved this by moulding a pattern of tiny cylindrical pillars on the face of the hydrocarbon membrane. The pillars protrude into a softened skin of the electrode with heat. The mechanical bond sets and strengthens as the material cools and absorbs water. The pillar-patterned hydrocarbon membrane is cast using silicone moulds.
Professor Kim said, “This physically fastened bond is almost five times stronger and harder to separate than current bonds between the same layers.”
The new interlocking method also appears to offer a way to bond many types of hydrocarbon membranes that, until now, have been rejected because they couldn’t be fastened robustly. This would make hydrocarbon membranes practical for a number of applications beyond fuel cells such as rechargeable “redox flow” batteries.
The research team is now developing a stronger and more scalable interlocking interface for their nanoscale fasteners.

KAIST Hosts the Wearable Computer Contest 2015
“What you see is a compact electronic system on a dust mask, which monitors the amount of dust taken in by a worker and lets other workers know if the person is injured in an industrial site,” said Bum Taek Jung, a Master’s candidate from Sungkyunkwan University during the Wearable Computer Contest 2015 held in KI building of KAIST on November 5, 2015.
He explained his interest in developing this system, “Dust-related respiratory diseases and falling accidents are still prevalent in industrial sites.” He added, “Using the smart dust mask helps monitoring workers’ physical condition in real time, allowing us to cope with accidents in a much more timely manner.” A smart dust mask is a portable device that alerts the user with orange or red light signs when the amount of dust inhaled by the user is higher than the threshold. Its application on a smartphone can also allow project managers to alert the risk of falling accidents to workers by employing a gyroscope and an accelerometer on the mask.
The Wearable Computer Contest 2015 met for the eleventh time at KAIST on November 5-6, 2015. A wearable computer refers to a portable device which users can wear directly on the body or on their clothes while moving. Products that can provide various services by connecting to a smartphone have become increasingly popular. The contest is an excellent opportunity for university students to design creative wearable systems similar to those often depicted in movies and comics.
This year 102 teams from universities all over the nation participated. After screening and evaluation of their presentations, only 8 teams in the product section and 3 teams in the ideas section were selected for the finals. Of the many entries to the contest, the ECG security system caught many people’s attention. The wearable, which attaches to a shirt, acts like an electrocardiogram. By comparing the ECG reading with the one stored in the data server, the wearable can authenticate the user. The system could be widely used by enterprises and financial companies where tight security and authentication are crucial.
The winners of the product and the ideas sections received USD 4,300 and usd 860 respectively along with Minister Prizes from the Minister of Science, ICT and Future Planning of Korea. The Chairman of the contest, Professor Hoi-Jun Yoo from the Electrical Engineering Department of KAIST said, “The contest will be a great opportunity for anyone to have a look at advanced wearable devices developed through close integration of state-of-the-art technologies and creative ideas from young minds.”

The 2015 Intelligent SoC Robot War Finals
The final round of the 2015 Intelligent SoC (System on Chip) Robot War took place from October 29, 2015 to November 1, 2015 at Kintex in Ilsan, Korea.
A “SoC robot” refers to an intelligent robot capable of autonomous object recognition and decision making by employing advanced semiconductor and information technology.
First hosted in 2002, the Intelligent SoC Robot War cultivates top talents in the field of semiconductors and seeks to revitalize Korea’s information technology (IT) and semiconductor industries.
The event consists of two competitions: HURO and the Tae Kwon Do Robot.
In the HURO competition, participating robots sequentially complete eight assignments without outside controls. Whichever robot finishes the highest number of tasks and spends the shortest amount of time for the completion of assignments wins the competition.
At the HURO competition, a SoC robot overcomes obstacles.
The Tae Kwon Do Robot competition includes Korea’s traditional martial arts into robotics. Here, the winner is selected by sparring between a pair of competitors. The camera attached to the robot’s head recognizes the position of the opponent and the distance between them. From that, the robot takes actions such as punching or kicking.
Two robots are vying for the title of the Tae Kwon Do Robot.
This year, 570 people from 104 teams from all over the nation applied, and after preliminaries, 26 teams entered the finals.
The winners of the HURO and Tae Kwon Do Robot competitions receive awards from the president and prime minister of Korea, respectively.
The Chairman of the Intelligent SoC Robot War, Professor Hoi-Jun Yoo of Electrical Engineering Department at KAIST, said,
“Korea’s strength in semiconductors and information technology can serve as a great potential to advance the development of intelligent robots. We hope that our experiences in this competition will allow Korea to excel in this field.”

KAIST Invites Entrepreneurs and Experts to Participate in a Social Technology Innovation Symposium
The Research Institute for Social Technology and Innovation (RISTI) at KAIST hosted the Social Technology Innovation Symposium on November 4, 2015 in KI building, to which 100 social business entrepreneurs and experts in the field were invited.
Social businesses refer to activities of companies, which strive to resolve social problems such as environmental issues, income inequality, and aging societies while seeking profit at the same time. This is different from companies taking social responsibility and non-profit organization serving the community in that they attempt to solve social problems through a sustainable business model.
Held under the theme of “technology capabilities of companies and social business strategies,” this symposium was the first to gather representatives from social venture companies, medium-sized enterprises, and major companies at one place to share their experiences in a social business and to discuss future tasks.
The symposium was divided into sessions with three different topics ranging from social business strategies using information technology, a social business and its business model, and social business strategies of major companies.
The symposium started with keynote speeches delivered by Professor HongKyu Lee, RISTI, and Professor Hong-Tak Lim, RISTI, who discussed the role of technology in a social business. It was followed by plenary sessions led by CEOs who are running social businesses such as the Sharing and Technologies Incorporated Project, Simwon Technology, Ecojun Company, Underdogs, and the Farming Fund as well as by representatives from a social responsibility section of CJ management team and the social responsibility council of SK. In the future, these talks will serve as a medium to share their experiences in social businesses and to discuss the role of technology in the business. Some talks touched upon topics such as development of platforms for social innovation, social businesses employing disabled workers, and crowd funding for farming.
The Director of RISTI, Professor HongKyu Lee said, “The symposium will be the first to have people from leading companies in social businesses in Korea in one place.” He added, “This will be a great opportunity for anyone to know what will be the future of social businesses, which were created to solve the social problems caused by capitalism.”
The symposium was sponsored by the Ministry of Trade, Industry, and Energy of Korea.
