Education 3.0: a change from teaching to learning
On October 16th, educationalists and Presidents from research-oriented universities around the world gathered in Seoul to attend the 2012 International Presidential Forum on Global Research Universities, where KAIST introduced its new smart learning model ‘Education 3.0’.
Smart learning ‘Education 3.0’ allows students to learn from lectures given by renowned scholars through the internet and encouraged student to professor discussion. This technology was created to deal with the ever-changing classroom dynamics due to the advancement of IT technology.‘Education 3.0’ differs from the traditional teaching-based lectures in that it offers a platform for self-directed learning. KAIST is working to spread ‘Education 3.0’ by providing specialized classrooms and running an online learning platform that complements it.
This spring, KAIST adopted ‘Education 3.0’ in 3 courses and received high praise from students (a rating of 4.4 out of 5.0). Hence, the number of courses was extended to 10 this fall.
Through this gathering, KAIST hopes to develop cooperative connections between foreign universities to share learning platforms and contents. On October 16th, KAIST signed a MOU with Denmark’s Danmarks Tekniske Universitet (DTU) to provide a cyber-dual degree program using ‘Education 3.0’. Hence, students studying Web science and Digital Media in either KAIST or DTU can receive degrees from both schools without physically visiting them.
President Suh said that “‘Education 3.0’ provides a new paradigm of learning which moves from the tradition cramming method of teaching to self-directed learning” and that this model will help the globalization of KAIST by initiating global cooperation with foreign universities.
Over 60 Universities from 27 different countries attended the forum, including ULCA and Caltech from the United States, DTU from Denmark, University of Southampton and University of York from England, University of Queensland from Australia, Nanyang Technological University from Singapore and Tokyo Institute of Technology from Japan. Members from Korean Universities such as Hanyang University, Handong Global University, Sogang University and Sookmyung Women"s University also attended.

Professor Soon-Heung Chang meets with Bill Gates and discusses possible collaboration
Professor Soon-Heung Chang from the Department of Nuclear and Quantum Engineering, KAIST, who is also the president of Korea Nuclear Society (KNS), met Bill Gates, the co-founder and former chief executive officer (CEO) of Microsoft, on August 16, 2012 and discussed ways to cooperate for the development of a sodium-cooled fast reactor (SFR), a next generation nuclear power reactor.
According to Professor Chang, Bill Gates was amazed at Korea’s successful bids for nuclear power plants in the United Arab Emirates, even though Korea was a latecomer in the field of nuclear power. Bill Gates also showed a keen interest in Korea’s low electricity rates.
Gates focuses on solving fundamental problems in order to help improve the quality of life for humanity, rather than short-term temporary solutions, through infrastructure development such as energy. Particularly, he considers nuclear power as one of the most effective ways to supply clean energy which can provide electricity at a low cost while keeping carbon dioxide emission levels much lower than fossil fuels.
Bill Gates is a primary investor for an energy company called “TerraPower” based in Bellevue, Washington. TerraPower develops and commercializes nuclear power technology for a traveling wave reactor (TWR) that is designed to use spent fuels, i.e., depleted uranium, and runs technically “forever” because once fueled, the reactor does not need to be refueled for over 50 years. TerraPower’s TWR is to use metallic fuel, and Korea is the only country that currently develops SFR (KALIMER 600) using metallic fuel.
“Korea has an outstanding supply chain for the entire lifecycle of a nuclear power station from equipment manufacturing to operation,” said Professor Chang, while emphasizing the synergistic effects of forming partnership between Korea and TerraPower.
Professor Chang emphasized that Korea should create an opportunity based on lessons learned from the Fukushima crisis and actively move forward to achieve its leading position in the field of next generation nuclear reactors. He said that cooperation with Bill Gates will be a significant step towards the development of next generation nuclear reactors.
About Sodium-cooled Fast Reactor (SFR)
Sodium-cooled Fast Reactor (SFR) is a next-generation nuclear power reactor that will use spent fuels from conventional reactors. Arrangement of a fuel recycling system in
conjunction with currently-developing pyroprocessing technology would enable U-238, which makes up over 99% of natural uranium, to be used as a nuclear fuel. This would greatly reduce the toxicity and volume of spent fuels by up to 1,000 times and 100 times respectively when compared to existing reactors. This is truly a breakthrough innovation in spent fuel disposal and recycling.

Liver Damage Mechanism of Hepatitis C Proven
KAIST researchers found mechanics behind a Hepatitis C virus, thereby taking a step closer to the development of a cure for Hepatitis C.
Professor Choi Chul Hui (Department of Biological and Brain Engineering) and Professor Shin Eui Chul (Graduate School of Medical Sciences) proved, for the first time in the world, the mechanism behind liver damage of a patient with Hepatitis C.
It is anticipated that this discovery will allow for the development of a Hepatitis C cure that has no side effects and little Liver damage.
Hepatitis C is an immune response of the body to the Hepatitis C virus and causes liver irritation.
Around 170million people are infected with Hepatitis C worldwide including 1% of the Korean population. Once infected, most cases turn into chronic cases and may lead to liver cancer.
However it was impossible to infect Hepatitis C within a test tube cell environment until 2005 and up till then Chimpanzees were used to study the virus which proved to be a huge barrier to research.
The research team used cells infected with Hepatitis C virus and found out that the virus works by increasing the destruction of cells by the TNF-a protein responsible for the cell’s immune response.
In addition the protein structure of the virus that causes this reaction was successfully found.
Conventionally the Hepatitis C medication focused on the suppressing the growth of the virus and therefore had many side effects.
The experimental results allow new medication aimed at suppressing the actual mechanism of liver damage to be discovered.
The result was selected as the cover dissertation of the September Edition of the Hepatolog magazine.

Ultra Elastic Electrode Material Developed
KAIST research team succeeded in developing the next generation flexible and elastic electrode material crucial in the development of flexible displays, wearable computers, and etc.
Professor Jeon Seok Woo’s team of the department of Materials Science and Engineering succeeded in the development of a super elastic material.
The result of the experiment was introduced as the research highlight in Nature Communications and is especially significant as the main driving force behind the achievement were domestic researchers.
Professor Jeons team developed a structured three dimensional nano-porous structure over a 1inch by 1inch area that is 10micrometers in thickness. The structure is fabricated using world’s largest area three dimensional nano patterning technique.
The nano-porous structure was injected with elastomeric material and was subsequently removed to yield an inverse three dimensional elastic nano material. The pores were infiltrated with liquid conductive material which yielded a super elastic flexible electrode.
The fabricated electrode showed amazing elasticity levels and was able to light LED lamps in a 200% stretched state without decrease in electrical conductivity.
Conventional methods included folding and expanding a material like an accordion or creating a mesh-like structure by making holes in the material. However these methods yielded materials with limited elasticity and even 100% stretching resulted in the drastic decrease in electrical conductivity.
Professor Jeon expects the domestically developed technology to obtain the upper hand in the market and make great contributions in both science and society.

Commercialization of Carbon Capture and Storage Technology Speeds up
KAIST research team successfully developed the ideal method for carbon dioxide transportation, which is crucial in the capturing and underground storage of carbon dioxide technology.
Professor Jang Dae Joon of the department of Ocean Systems Engineering developed a carbon dioxide transportation that minimizes evaporative gases.
The new technology is the final piece of the three part carbon capture storage which involves capture, transportation, and storage of carbon dioxide. The completion of the three part technology will allow for commercialization in the near future.
Carbon Capture and Storage technology is regarded as the technology that will reduce carbon dioxide levels. It captures the carbon dioxide emitted from power plants and factories and storing them permanently in empty oil fields underground.
If the post Kyoto Protocol was to be implemented from 2013, Korea will not be able to shirk from the need to reduce carbon emissions. Therefore the Korean government set out to reduce 32 million tons of carbon dioxide (10% of predicted carbon reduction) until 2030. In response to the government’s efforts to reduce carbon dioxide emissions, Korean research teams like KAIST have responded.
Professor Jang’s team succeeded in developing the core technology for underground storage in the 2009 ‘Carbon dioxide Transport and Injection Terminal Project’. And as the final piece of the puzzle the team developed an optimization solution that addressed the evaporating gases emitted from carbon dioxide during transportation.
Professor Jang’s team focused on the required low temperature and high pressure conditions in liquid carbon dioxide transport.
The problem lies in the temperature gradient which can cause the transport canister to explode.
The solution developed by the team is to evaporate carbon dioxide in a pressurized contained which is then re-liquidated.
External variables like price of oil, carbon taxation, etc. have been considered and the process was optimized accordingly.
The result of Professor Jang’s team’s solution to Carbon Capture and Storage was stored in the online edition of International Journal of Greenhouse Gas Control.

KAIST researchers verify and control the mechanical properties of graphene
KAIST researchers have successfully verified and controlled the mechanical properties of graphene, a next-generation material. Professor Park Jung Yong from the EEWS Graduate School and Professor Kim Yong Hyun from the Graduate School of Nanoscience and Technology have succeeded in fluorinating a single atomic-layered graphene sample and controlling its frictional and adhesive properties. This is the first time the frictional properties of graphene have been examined at the atomic level, and the technology is expected to be applied to nano-sized robots and microscopic joints.
Graphene is often dubbed “the dream material” because of its ability to conduct high amounts of electricity even when bent, making it the next-generation substitute for silicon semiconductors, paving the way for flexible display and wearable computer technologies. Graphene also has high potential applications in mechanical engineering because of its great material strength, but its mechanical properties remained elusive until now.
Professor Park’s research team successfully produced individual graphene samples with fluorine-deficiency at the atomic level by placing the samples in Fluoro-xenon (XeF2) gas and applying heat. The surface of the graphene was scanned using a micro probe and a high vacuum atomic microscope to measure its dynamic properties.
The research team found that the fluorinated graphene sample had 6 times more friction and 0.7 times more adhesiveness than the original graphene. Electrical measurements confirmed the fluorination process, and the analysis of the findings helped setup the theory of frictional changes in graphene.
Professor Park stated that “graphene can be used for the lubrication of joints in nano-sized devices” and that this research has numerous applications such as the coating of graphene-based microdynamic devices.
This research was published in the online June edition of Nano Letters and was supported by the Ministry of Science, Technology, and Education and the National Research Foundation as part of the World Class University (WCU) program.

New wireless charging device developed
The On-line Electric Vehicle (OLEV) developed by KAIST has made a step towards commercialization with the development of a more economic wireless charging device.
Professor Chun-Taek Rim from the Department of Nuclear and Quantum Engineering at KAIST has developed a new I-shaped wireless charging device that differs from the pre-existing rail-type electricity feeder. This device can be modularly produced and requires relatively less construction, significantly reducing the cost of implementation.
The KAIST OLEV is a new concept electric car that has a special electricity collecting device underneath it. The car’s battery is charged by magnetic fields produced from electric lines buried 15cm underneath the road. The vehicle was first tested in 2009, making it the first wireless electric car in the world. OLEV can be charged during stoppage time between traffic lights and receives real-time power when running. OLEV is currently in operation at the KAIST Munji Campus in Daejeon and is also being exhibited at the Yeosu Expo and Seoul Grand Park.
The device itself has a charging capacity of 15kW, and the electricity is supplied through an electricity feeder with a width of 80cm with a space interval of 20cm. Despite being hailed as a technological breakthrough and revolutionary concept, KAIST OLEV has been criticized for problems in commercialization, due to the difficulties in installing wires beneath existing roads, which costs a considerable amount of money.
The new I-shaped wireless charging device reduces the width of the electricity feeder by 10cm, a mere one-eighth of the size of the previous version, and greatly increases the charging power to 25kW. Furthermore, the left and right permissible space of automobiles has increased to 24cm and the magnetic field complies with the international design guidelines, making the OLEV safe for the human body.
The reduction of the width has made the mass production of modules possible, making the installation of KAIST OLEV more economical and marketable. Professor Rim emphasized that compared with the existing rail-type electricity feeder, the new technology will need only one-tenth of the construction time and 80% of the cost, significantly improving OLEV’s constructability and workability.
The research was published in the IEEE Transactions on Power Electronics last December, and Professor Rim was invited to talk at the Conference on Electric Roads & Vehicles, which was held in February in the United States, about the new technology.

Flexible Nanogenerator Technology
KAIST research team successfully developed the foundation technology that will enable to fabrication of low cost, large area nanogenerator.
Professor Lee Gun Jae’s team (Department of Materials Science and Engineering) published a dissertation on a nanogenerator using nanocomplexes as the cover dissertation of the June edition of Advanced Materials.
The developed technology is receiving rave reviews for having overcome the complex and size limitations of the nanogenerator fabrication process.
A nanogenerator is an electricity generator that uses materials in the nanoscale and uses piezoelectricity that creates electricity with the application of physical force.
The generation technology using piezoelectricity was appointed as one of top 10 promising technologies by MIT in 2009 and was included in the 45 innovative technologies that will shake the world by Popular Science Magazine in 2010.
The only nanogenerator thus far was the ZnO model suggested by Georgia Tech’s Professor Zhong Lin Wang in 2005.
Professor Lee’s team used ceramic thin film material BaTiO3 which has 15~20 times greater piezoelectric capacity than ZnO and thus improved the overall performance of the device. The use of a nanocomplex allows large scale production and the simplification of the fabrication process itself.
The team created a mixture of PDMS (polydimethylsiloxane) with BaTiO3 and either of CNT (Carbon Nanotube) or RGO (Reduced Graphene Oxide) which has high electrical conductivity and applied this mixture to create a large scale nanogenerator.
