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’.

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.

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.

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.
