Midam Scholarship Society Receives Minister of Education, Science, and Technology Prize for Education Donation
Midam Scholarship Society, consisting of KAIST students, has been awarded the First Korea Education Donation Grand Prize from the Ministry of Education, Science and Technology.
The Education Donation Prize has been created in order to encourage those university clubs that have been increasing awareness of education donation and at the same time donating educational services themselves.
Midam Scholarship Society was established by KAIST students in 2009 to provide educational services to those students from low income families. Currently over 200 students from six different universities (KAIST, UNIST, Pusan University, Chonnam University, Kyungpook National University, Kumoh Engineering University) are involved in the Midam Scholarship Society.
Approximately 70 students participate in the KAIST Midam Scholarship Society. The classes take place in the classrooms every week for three hours over a period of three months. The classes are offered to over 1,000 high school students in and near DaeJeon.

3D contents using our technology
Professor Noh Jun Yong’s research team from KAIST Graduate School of Culture Technology has successfully developed a software program that improves the semiautomatic conversation rate efficiency of 3D stereoscopic images by 3 times.
This software, named ‘NAKiD’, was first presented at the renowned Computer Graphics conference/exhibition ‘Siggraph 2012’ in August and received intense interest from the participants.
The ‘NAKiD’ technology is forecasted to replace the expensive imported equipment and technology used in 3D filming.
For multi-viewpoint no-glasses 3D stereopsis, two cameras are needed to film the image. However, ‘NAKiD’ can easily convert images from a single camera into a 3D image, greatly decreasing the problems in the film production process as well as its cost.
There are 2 methods commonly used in the production of 3D stereoscopic images; filming using two cameras and the 3D conversion using computer software.
The use of two cameras requires expensive equipment and the filmed images need further processing after production. On the other hand, 3D conversion technology does not require extra devices in the production process and can also convert the existing 2D contents into 3D, a main reason why many countries are focusing on the development of stereoscopic technology.
Stereoscopic conversion is largely divided in to 3 steps; object separation, formation of depth information and stereo rendering. Professor Noh’s teams focused on the optimization of each step to increase the efficiency of the conversion system.
Professor Noh’s research team first increased the separation accuracy to the degree of a single hair and created an algorithm that automatically fills in the background originally covered by the separated object.
The team succeeded in the automatic formation of depth information using the geographic or architectural characteristic and vanishing points. For the stereo rendering process, the team decreased the rendering time by reusing the rendered information of one side, rather than the traditional method of rendering the left and right images separately.
Professor Noh said that ‘although 3D TVs are becoming more and more commercialized, there are not enough programs that can be watched in 3D’ and that ‘stereoscopic conversion technology is receiving high praise in the field of graphics because it allows the easy production of 3D contents with small cost’.

DNA based semiconductor technology developed
Professor Park Hyun Gyu’s research team from the Department of Chemical and Biomolecular Engineering at KAIST has successfully implemented all logic gates using DNA, a feat that led the research to be published as the cover paper for the international nanotechnology paper "Small".
Even with the latest technology, it was impossible to create a silicon based semiconductor smaller than 10nm, but because DNA has a thickness of only 2nm, this could lead to the creation of semiconductors with groundbreaking degrees of integration.
A 2 nm semiconductor will be able to store 10,000 HD movies within a size of a postage stamp, at least 100 times more than the current 20nm semiconductors.
DNAs are comprised of 4 bases which are continually connected: Adenine (A) with Thymine (T), and Guanine (G) with Cytosine (C).
For this research, the team used the specific binding properties of DNA, which forms its helix-shape, and a circular molecular beacon that has fluorescent signaling properties under structural changes.
The research team used input signals to open and close the circular DNA, the same principle that is applied to logic gates in digital circuits.
The output signal was measured using the increase and decrease of the fluorescent signal from the molecular beacon due to the opening and closing of the circular DNA respectively.
The team overcame the limited system problems of the existing logic gates and managed to implement all 8 logic gates (AND, OR, XOR, INHIBIT, NAND, NOR, XNOR, IMPlCATION). A multilevel circuit that connects different logic gates was also tested to show its regenerative properties.
Professor Park said that “cheap bio-electric devices with high degrees of integration will be made possible by this research” and that “there will be a large difference in the field of molecular level electronic research”
Mr. Park Gi Su, a doctoral candidate and the 1st author of this research, said that “a DNA sequence of 10 bases is only 3.4nm long and 2nm thick, which can be used to effectively increase the degree of integration of electronic devices” and that “a bio computer could materialize in the near future through DNA semiconductors with accurate logic gates”.
XOR Gate: The output signal 1 comes through the open circular DNA when either input DNA A or input DNA B is present. When both inputs are not present, the flourescent signal does not come through

Anonymous philanthropist donates 5.5 billion won to KAIST
An unnamed philanthropist donated a large sum of money to KAIST to be used as funds for the school"s development.
On September 6th, the donor met with President Suh to donate a sum of 5.5 billion won to the school for the development of science and technology.
A KAIST representative announced that the donor did not want to be named and that he was greatly impressed by President Suh"s and KAIST"s efforts towards reformation. The philanthropist wanted the donation to be used for research funds and financial aid.
President Suh said that "KAIST was deeply thankful and that it would work harder to show fulfill the donor"s wishes" and that the money would indeed be used for research and the students.
This was the 6th largest donation since the start of President Suh"s post in July 2006. Since 2006, the accumulated KAIST development fund has increased 30 times, from 5.9 billion won at the end of 2006 to 180 billion won in September 2012.

Jellyfish removal robot developed
Professor Myung Hyun’s research team from the Department of Civil and Environmental Engineering at KAIST has developed a jellyfish removal robot named ‘JEROS’ (JEROS: Jellyfish Elimination RObotic Swarm).
With jellyfish attacks around the south-west coast of Korea becoming a serious problem, causing deaths and operational losses (around 3 billion won a year), Professor Myung’s team started the development of this unmanned automatic jellyfish removal system 3 years ago.
JEROS floats on the surface of the water using two long cylindrical bodies. Motors are attached to the bodies such that the robot can move back and forth as well as rotate on water. A camera and GPS system allows the JEROS to detect jellyfish swarm as well as plan and calculate its work path relative to its position.
The jellyfish are removed by a submerged net that sucks them up using the velocity created by the unmanned sailing. Once caught, the jellyfish are pulverized using a special propeller.
JEROS is estimated to be 3 times more economical than manual removal. Upon experimentation, it showed a removal rate of 400kg per hour at 6 knots. To reach similar effectiveness as manual net removal, which removes up to 1 ton per hour, the research team designed the robot such that 3 or more individual robots could be grouped together and controlled as one.
The research team has finished conducting removal tests in Gunsan and Masan and plan to commercialize the robot next April after improving the removal technology. JEROS technology can also be used for a wide range of purposes such as patrolling and guarding, preventing oil spills or removing floating waste. This research was funded by the Ministry of Education, Science and Technology since 2010.
