KAIST shocks the world with its creativity
Researchers at KAIST yielded great results at the world’s leading international Human Computer Interaction Society.
Professor Lee Gi Hyuk’s (Department of Computer Sciences) and Professor Bae Seok Hyung’ (Department of Industrial Design) respective teams received awards in two criteria in student innovation contest and was the only domestic university that presented their thesis at the ACM Symposium on User Interface Software.
The ACM UIST holds a student innovation contest prior to its opening. This year’s topic was the pressure sensing multi touch pad of Synaptics and involved 27 prestigious universities including MIT and CMU.
The KAIST team (Ki Son Joon Ph.D. candidate, Son Jeong Min M.A. candidate of Department of Computer Sciences and Woo Soo Jin M.A. candidate of Department of Industrial Design) designed a system that allows modulated control by attaching a simple structure to the pressure sensing multi touch pad.
The second KAIST team (Huh Seong Guk Ph.D. candidate, Han Jae Hyun Ph.D. candidate, Koo Ji Sung Ph.D. candidate at the Department of Computer Sciences, and Choi Ha Yan M.A. candidate at Department of Industrial Design) designed a system that utilizes a highly elastic fiber to allow the sensing of lateral forces. They also created a slingshot game application which was the second most popular system.
In the thesis session Professor Bae’s team (Lee DaWhee Ph.D. candidate, Son Kyung Hee Ph.D. candidate, Lee Joon Hyup M.A. candidate at Department of Industrial Design) presented a thesis that dealt with the technology that innovated the table pen for displays.
The new ‘phantom pen’ solved the issue arising from the hiding effect of the pen’s contact point and the display error due to the thickness of the display. In addition the ‘phantom pen’ has the ability to show the same effects as crayons or markers in a digital environment.

The control of light at the nano-level
Professor Min Bumki
Professor Min Bumki’s research team from the Department of Mechanical Engineering at KAIST have successfully gained control of the transmittance of light in optical devices using graphene* and artificial 2-dimensional metamaterials**.
* Graphene : a thin membrane composed of pure carbon, with atoms arranged in a regular hexagonal pattern
** Metamaterials : artificial materials engineered to have properties that may not be found in nature
The research results were published in the recent online edition (September 30th) of Nature Materials, a sister journal of the world renowned Nature journal, under the title ‘Terahertz waves with gate-controlled active graphene metamaterials’
Since the discovery of graphene in 2004 by Professors Novoselov and Geim from the University of Manchester (2010 Nobel Prize winners in Physics), it has been dubbed “the dream material” because of its outstanding physical properties.
Graphene has been especially praised for its ability to absorb approximately 2.3% of near infrared and visible rays due to its characteristic electron structure. This property allows graphene to be used as a transparent electrode, which is a vital electrical component used in touch screens and solar batteries. However, graphene’s optical transmittance was largely ignored by researchers due to its limited control using electrical methods and its small optical modulation in data transfer.
Professor Min’s team combined 0.34 nanometer-thick graphene with metamaterials to allow a more effective control of light transmittance and greater optical modulation. This graphene metamaterial can be integrated in to a thin and flexible macromolecule substrate which allows the control of transmittance using electric signals.
This research experimentally showed that graphene metamaterials can not only effective control optical transmittance, but can also be used in graphene optical memory devices using electrical hysteresis.
Professor Min said that “this research allows the effective control of light at the nanometer level” and that “this research will help in the development of microscopic optical modulators or memory disks”.

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.

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.

Professor Song Joon Hwa develops new Location Tracking Application
Professor Song Joon Hwa developed a location tracking application that alerts the teacher when students on field trips stray too far from the group via a smartphone and a headset.
Conventional Location Tracking Applications utilize GPS systems and as a consequence does not function indoors where the satellite signal is nonexistent. However Professor Song’s method is unique in the fact that it utilizes radio waves which allows signal transfer both indoors and outdoors.
In addition different alerts are given off in difference locations and therefore the technology can be applied in finding the effectiveness of the field trip and the social behaviors of students.

Successful development and analysis of mesoporous quasicrystal structures
Professor Osamu Terasaki’s research team from the EEWS Graduate School at KAIST successfully synthesized mesoporous quasicrystalline silica and developed a new method of analyzing its growth. The theory proposed by the team laid the foundation for the scientific examination of quasicrystal phenomena during the formation of micelles particles, a type of soft matter. The paper was published in the July edition of Nature magazine.
Scientists have faced difficulty in systematically explaining the mesoporous quasicrystal structures that are found in solidified versions of soft matter systems. However, the theoretical foundation from this research is expected to help promote the research and development of new nano-structured materials.
Mesoporous quaicrystals are soft matters that have high symmetry and a larger characteristic length scale than the nanoscale, thereby making it possible to develop materials that have controllable optical properties. This technology can be applied to the sustainable storage, use, and reproduction of energy.
Professor Terasaki’s team succeeded in synthesizing mesoporous quasicrystalline silica and proved the formation of dodecagonal column-shaped crystals as well as dodecagonal, rotationally symmetric electron diffraction patterns near the crystals using Transmission Electron Microscopy.
Quasicrystals are an abbreviation of ‘quasiperiodic crystals’ and have what is called the ‘third solid’ property; they have a structural arrangement that is between arranged crystal structures, such as metals, and non-crystalline structures, such as glass. This crystalline structure was only recently found, and the 2011 Nobel Chemistry Award was given to research in this field.
When porous materials are synthesized into quasicrystals, the crystalline structures of the pores can be designed and controlled in any way, making it possible to create new materials for a wide range of fields.
Professor Terasaki said that ‘The discovery of highly symmetric quasicrystals can lead to the alteration of a material’s optical properties, allowing the development of photonic crystals in the visible spectra.’ He also explained that this control of a material’s optical energy absorption could be the core technology behind energy harvesting.
This research was jointly conducted by Professor Terasaki from the EEWS Graduate School at KAIST and Stockholm University in Sweden.

Professor Bae Sang Min Wins Multiple Prestigious Design Awards
Summer is perfect for many outdoor activities, but it is also the season for mosquitoes, an annoying pest that makes outdoor experiences unpleasant and sometimes even dangerous. An easy-to-use and environmentally-friendly spray, “Sound Spray” (http://idsa.org/soundspray-self-generating-non-toxic-ultrasonic-anti-mosquito-spray), which repels mosquitoes by setting off ultrasonic waves, has been developed by a research team at KAIST. The spray produces sounds similar to those of mosquitoes’ natural predators.
Sound Spray made the list of finalists in the category of "Social Impact Design" from the 2012 International Design Excellence Awards (IDEA). The IDEA is one of the most renowned design competitions in the world, which has been held annually by the Industrial Designers Society of America (IDSA).
Inside Sound Spray is a battery that generates electricity when a user shakes the spray bottle. Electrical energy produced by the battery creates an ultrasonic sound that mosquitoes dislike, thereby discouraging their contact with human skin. Professor Sangmin Bae from the Department of Industrial Design at KAIST explains,
“In regions such as Africa or Southeast Asia, mosquitoes are still posing a big threat to public health. Unlike Freon-based, disposable insect repellents on the market, Sound Spray is eco-friendly, easy to carry around, reusable, and affordable. I plan to commercialize and distribute it to nations in Africa or Southeast Asia to help them combat against malaria, an infectious disease that patients contract through mosquito bites.”
Professor Bae also received another award from the 2012 IDEA in the area of Commercial and Industrial Products: a bronze medal for a milling machine, the Namsun Milling Machine (http://www.idsa.org/namsunnew-innovative-milling-machine-design). The machine has large windows on each side of its main body that display a transparent workflow so that users easily understand the machine’s operation status. Curved lines are actively used for the exterior design of the machine to create a more friendly work environment.
In addition to the 2012 IDEA, Professor Bae has participated in other major international design awards, including the Red Dot Award, the If Design Award Japan, and the Good Design Award, from which his research team has received a total of 41 prizes.
Professor Bae initiated a campaign in 2005 called “Philanthropy Design,” through which he has donated many of his designs to help people in need. For more on his research, please visit http://www.coroflot.com/frame29/Portfolio1.
