Professor Woontack Woo Demonstrates an Optical Platform Technology for Augmented Reality at Smart Cloud Show
Professor Woontack Woo of the Graduate School of Culture Technology at KAIST participated in the Smart Cloud Show, a technology exhibition, hosted by the university’s Augmented Human Research Center and presented the latest development of his research, an optical platform system for augmented reality.
This event took place on September 16-17, 2015 at Grand Seoul Nine Tree Convention Center in Seoul.
At the event, Professor Woo introduced a smart glass with an embedded augmented reality system, which permits remote collaboration between an avatar and the user’s hand.
The previous remote collaboration was difficult for ordinary users to employ because of its two-dimensional screen and complicated virtual reality system.
However, with the new technology, the camera attached to artificial reality (AR) glasses recognizes the user’s hand and tracks it down to collaborate. The avatar in the virtual space and the user’s hand interact in real space and time.
The key to this technology is the stable, real-time hand-tracking technique that allows the detection of the hand’s locations and the recognition of finger movements even in situations of self-occlusion.
Through this method, a user can touch and manipulate augmented contents as if they were real-life objects, thereby collaborating remotely with another user who is physically distant by linking his or her movements with an avatar.
If this technology is adopted widely, it may bring some economic benefits such as increased productivity due to lower costs for mobility and reduction in social overhead costs from the decrease in the need of traveling long distance.
Professor Woo said, “This technology will provide us with a greater opportunity for collaboration, not necessarily restricted to physical travelling, which can be widely used in the fields of medicine, education, entertainment, and tourism.”
Professor Woo plans to present his research results on hand-movement tracking and detection at the 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI 2015), to be held on October 28-30, 2015, at Kintex in Goyang, Korea.
He will also present a research paper on remote collaboration at the ICAT-EGVE 2015 conference, the merger of the 25th International Conference on Artificial Reality and Telexistence (ICAT 2015) and the 20th Eurographics Symposium on Virtual Environments (EGVE 2015), which will take place on October 28-30, 2015 at the Kyoto International Community House, Kyoto, Japan.

'Engineered Bacterium Produces 1,3-Diaminopropane'
A research team led by Distinguished Professor Sang Yup Lee of the Department of Chemical and Biomolecular Engineering at KAIST reported, for the first time, the production of 1,3-diaminopropane via fermentation of an engineered bacterium.
1,3-Diaminopropane is a three carbon diamine, which has a wide range of industrial applications including epoxy resin and cross-linking agents, as well as precursors for pharmaceuticals, agrochemicals, and organic chemicals. It can also be polymerized with dicarboxylic acids to make polyamides (nylons) for use as engineering plastics, medical materials, and adhesives.
Traditionally, 1,3-diaminopropane is derived from petroleum-based processes. In effort to address critical problems such as the depletion of petroleum and environmental issues inherent to the petroleum-based processes, the research team has developed an Escherichia coli (E. coli) strain capable of producing 1,3-diaminopropane. Using this technology, 1,3-diaminopropane can now be produced from renewable biomass instead of petroleum.
E. coli as found in nature is unable to produce 1,3-diaminopropane. Metabolic engineering, a technology to transform microorganisms into highly efficient microbial cell factories capable of producing chemical compounds of interest, was utilized to engineer the E. coli strain. First, naturally existing metabolic pathways for the biosynthesis of 1,3-diaminopropane were introduced into a virtual cell in silico to determine the most efficient metabolic pathway for the 1,3-diaminopropane production. The metabolic pathway selected was then introduced into an E. coli strain and successfully produced 1,3-diaminopropane for the first time in the world.
The research team applied metabolic engineering additionally, and the production titer of 1,3-diaminopropane increased about 21 fold. The Fed-batch fermentation of the engineered E. coli strain produced 13 grams per liter of 1,3-diaminoproapne. With this technology, 1,3-diaminopropane can be produced using renewable biomass, and it will be the starting point for replacing the current petroleum-based processes with bio-based processes.
Professor Lee said, “Our study suggested a possibility to produce 1,3-diaminopropane based on biorefinery. Further study will be done to increase the titer and productivity of 1,3-diaminopropane.”
This work was published online in Scientific Reports on August 11, 2015.

3D Plasmon Antenna Capable of Focusing Light into Few Nanometers
Professors Myung-Ki Kim and Yong-Hee Lee, both of the Physics Department at KAIST, and their research teams have developed a three dimensional (3D) gap-plasmon antenna which can focus light into a space a few nanometers wide. Their research findings were published in the June 10th issue of Nano Letters.
Focusing light into a point-like space is an active research field with many applications. However, concentrating light into a smaller space than its wavelength is often hindered by diffraction. To tackle this problem, many researchers have utilized the plasmonic phenomenon of a metal where light can be confined to a greater extent by overcoming the diffraction limit.
Many researchers have focused on developing a two dimensional (2D) plasmon antenna and were able to focus a light under 5 nanometers wide. However, this 2D antenna revealed a challenge: the light disperses to the opposite end regardless of how small its beam was focused. To solve this difficulty, a 3D structure had to be employed to maximize the light's intensity.
Adopting the proximal focused-ion-beam milling technology, the KAIST research team developed a 3D four nanometer wide gap-plasmon antenna. By squeezing the photons into a 3D nano space of 4 x 10 x 10 nm3 size, the researchers were able to increase the intensity of light by 400,000 times stronger than that of the incident light. Capitalizing on the enhanced intensity of light within the antenna, they intensified the second-harmonic signal and verified that the light was focused in the nano gap by scanning cathodoluminescent images.
The researchers anticipate that this technology will improve the speed of data transfer and processing up to the level of a terahertz (one trillion times per second) and to enlarge the storage volume per unit area on hard disks by 100 times. In addition, high definition images of submolecule size can be taken with actual light, instead of with an electron microscope, while improving the semiconductor process to a smaller size of few nanometers.
Professor Kim said, “A simple yet ingenious idea has shifted the research paradigm from 2D gap-plasmon antennas to 3D antennas. This technology will see numerous applications including in the field of information technology, data storage, imaging medical science, and semiconductor processes.”
The research was sponsored by the National Research Foundation of Korea.

KAIST to support the Genetic Donguibogam Research Project for global market entry of a new natural drug produced by Green Cross Corporation HS
In the wake of the spread of the Middle East Respiratory Syndrome (MERS), sales of immune-enhancing products in Korea such as red and white ginseng have risen dramatically. Ginseng is one of Korea’s major health supplement it exports, but due to the lack of precise scientific knowledge of its mechanism, sales of ginseng account for less than 2% of the global market share.
The Genetic Donguibogam Research Project represents a group of research initiatives to study genes and environmental factors that contribute to diseases and to discover alternative treatments through Eastern medicine. The project is being led by KAIST’s Department of Bio & Brain Engineering Professor Do-Heon Lee.
Professor Lee and Chief Executive Officer Young-Hyo Yoo of Green Cross Corporation HS, a Korean pharmaceutical company, signed a memorandum of understanding (MOU), as well as a non-disclosure agreement (NDA) to develop a naturally derived drug with an enhanced ginsenoside, pharmacological compounds of ginseng, for the global market entry of BST204 on June 10, 2015.
Donguibogam is the traditional Korean source for the principles and practice of Eastern medicine, which was compiled by the royal physician Heo Jun and first published in 1613 during the Joseon Dynasty of Korea.
Cooperating with Green Cross Co., HS, KAIST researchers will use a multi-component, multi-target (MCMT)-based development platform to produce the new natural drug, BST204. This cooperation is expected to assist the entry of the drug into the European market.
Green Cross Co., HS has applied a bio-conversion technique to ginseng to develop BST204, which is a drug with enhanced active constituent of aginsenosides. The drug is the first produced by any Korean pharmaceutical company to complete the first phase of clinical trials in Germany and is about to start the second phase of trials.
Professor Do-Heon Lee, the Director of the project said, “Genetic Donguibogam Research Project seeks to create new innovative healthcare material for the future using integrated fundamental technologies such as virtual human body computer modelling and multi-omics to explain the mechanism in which natural ingredients affect the human body.” He continued, “Especially, by employing the virtual human body computer modelling, we can develop an innovative new technology that will greatly assist Korean pharmaceutical industry and make it the platform technology in entering global markets.”
Young-Hyo Yoo, the CEO of Green Cross Co., HS, said, “For a new naturally derived drug to be acknowledged in the global market, such as Europe and the US, its mechanism, as well as its effectiveness and safety, should be proven. However, it is difficult and costly to explain the mechanism in which the complex composition of a natural substance influences the body. Innovative technology is needed to solve this problem.”
