KAIST developed an extremely low-powered, high-performance head-mounted display embedding an augmented reality chip
Walking around the streets searching for a place to eat will be no hassle when a head-mounted display (HMD) becomes affordable and ubiquitous. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed K-Glass, a wearable, hands-free HMD that enables users to find restaurants while checking out their menus. If the user of K-Glass walks up to a restaurant and looks at the name of the restaurant, today’s menu and a 3D image of food pop up. The Glass can even show the number of tables available inside the restaurant. K-Glass makes this possible because of its built-in augmented reality (AR) processor. Unlike virtual reality which replaces the real world with a computer-simulated environment, AR incorporates digital data generated by the computer into the reality of a user. With the computer-made sensory inputs such as sound, video, graphics or GPS data, the user’s real and physical world becomes live and interactive. Augmentation takes place in real-time and in semantic context with surrounding environments, such as a menu list overlain on the signboard of a restaurant when the user passes by it, not an airplane flight schedule, which is irrelevant information, displayed. Most commonly, location-based or computer-vision services are used in order to generate AR effects. Location-based services activate motion sensors to identify the user’s surroundings, whereas computer-vision uses algorithms such as facial, pattern, and optical character recognition, or object and motion tracking to distinguish images and objects. Many of the current HMDs deliver augmented reality experiences employing location-based services by scanning the markers or barcodes printed on the back of objects. The AR system tracks the codes or markers to identify objects and then align them with virtual reality. However, this AR algorithm is difficult to use for the objects or spaces which do not have barcodes, QR codes, or markers, particularly those in outdoor environments and thus cannot be recognized. To solve this problem, Hoi-Jun Yoo, Professor of Electrical Engineering at KAIST and his team developed, for the first time in the world, an AR chip that works just like human vision. This processor is based on the Visual Attention Model (VAM) that duplicates the ability of human brain to process visual data. VAM, almost unconsciously or automatically, disentangles the most salient and relevant information about the environment in which human vision operates, thereby eliminating unnecessary data unless they must be processed. In return, the processor can dramatically speed up the computation of complex AR algorithms. The AR processor has a data processing network similar to that of a human brain’s central nervous system. When the human brain perceives visual data, different sets of neurons, all connected, work concurrently on each fragment of a decision-making process; one group’s work is relayed to other group of neurons for the next round of the process, which continues until a set of decider neurons determines the character of the data. Likewise, the artificial neural network allows parallel data processing, alleviating data congestion and reducing power consumption significantly. KAIST’s AR processor, which is produced using the 65 nm (nanometers) manufacturing process with the area of 32 mm2, delivers 1.22 TOPS (tera-operations per second) peak performance when running at 250 MHz and consumes 778 miliWatts on a 1.2V power supply. The ultra-low power processor shows 1.57 TOPS/W high efficiency rate of energy consumption under the real-time operation of 30fps/720p video camera, a 76% improvement in power conservation over other devices. The HMDs, available on the market including the Project Glass whose battery lasts only for two hours, have revealed so far poor performance. Professor Yoo said, “Our processor can work for long hours without sacrificing K-Glass’s high performance, an ideal mobile gadget or wearable computer, which users can wear for almost the whole day.” He further commented:“HMDs will become the next mobile device, eventually taking over smartphones. Their markets have been growing fast, and it’s really a matter of time before mobile users will eventually embrace an optical see-through HMD as part of their daily use. Through augmented reality, we will have richer, deeper, and more powerful reality in all aspects of our life from education, business, and entertainment to art and culture.” The KAIST team presented a research paper at the International Solid-State Circuits Conference (ISSCC) held on February 9-13, 2014 in San Francisco, CA, which is entitled “1.22TOPS and 1.52mW/MHz Augmented Reality Multi-Core Processor with Neural Network NoC for HMD Applications.”Youtube Link: http://www.youtube.com/watch?v=wSqY30FOu2s&feature=c4-overview&list=UUirZA3OFhxP4YFreIJkTtXw

A Molecular Switch Controlling Self-Assembly of Protein Nanotubes Discovered
International collaborative research among South Korea, United States, and Israel research institutionsThe key to the treatment of cancer and brain disease mechanism The molecular switch that controls the self-assembly structure of the protein nanotubes, which plays crucial role in cell division and intracellular transport of materials, has been discovered. KAIST Bio and Brain Engineering Department’s Professor Myeong-Cheol Choi and Professor Chae-Yeon Song conducted the research, in collaboration with the University of California in Santa Barbara, U.S., and Hebrew University in Israel. The findings of the research were published in Nature Materials on the 19th. Microtubules are tube shaped and composed of protein that plays a key role in cell division, cytoskeleton, and intercellular material transport and is only 25nm in diameter (1/100,000 thickness of a human hair). Conventionally, cancer treatment focused on disrupting the formation of microtubules to suppress the division of cancer cells. In addition Alzheimer’s is known to be caused by the diminishing of structural integrity of microtubules responsible for intercellular material transport which leads to failure in signal transfer. The research team utilized synchrotron x-ray scattering and transmission electron microscope to analyze the self assemble structure of protein nanotubes to subnanometer accuracy. As a result, the microtubules were found to assemble into 25nm thickness tubules by stacking protein blocks 4 x 5 x 8nm in dimension. In the process, the research team discovered the molecular switch that controls the shape of these protein blocks. In addition the research team was successful in creating a new protein tube structure. Professor Choi commented that they were successful in introducing a new paradigm that suggests the possibility of controlling the complex biological functions of human’s biological system with the simple use of physical principles. He commented further that it is anticipated that the findings will allow for the application of bio nanotubes in engineering and that this is a small step in finding the mechanism behind cancer treatment and neural diseases.

KAIST Participates in the 2014 Davos Forum on January 22-25 in Switzerland
Through the sessions of the Global University Leaders Forum, IdeasLab, and Global Agenda Councils on Biotechnology, KAIST participants will actively engage with global leaders in the discussion of issues on education innovation and technological breakthroughs. The 2014 Annual Meeting of the World Economic Forum (WEF), known as the Davos Forum, will kick off on January 22-25 in Davos-Klosters, Switzerland, under the theme of "The Reshaping of the World: Consequences for Society, Politics, and Business." Each year, the Forum attracts about 2,500 distinguished leaders from all around the world and provides an open platform to identify the current and emerging challenges facing the global community and to develop ideas and actions necessary to respond to such challenges. President Sung-Mo Steve Kang and Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering, KAIST, will attend the Forum and engage in a series of dialogues on such issues as Massive Open Online Courses, new paradigms for universities and researchers, the transformation of higher education, the role and value of scientific discoveries, and the impact of biotechnology on the future of society and business. At the session entitled "New Paradigms for Universities of the Future" hosted by the Global University Leaders Forum (GULF), President Kang will introduce KAIST"s ongoing online education program, Education 3.0. GULF was created in 2006 by WEF, which is a small community of the presidents and senior representatives of the top universities in the world. Implemented in 2012, Education 3.0 incorporates advanced information and communications technology (ICT) to offer students and teachers a learner-based, team-oriented learning and teaching environment. Under Education 3.0, students study online and meet in groups with a professor for in-depth discussions, collaboration, and problem-solving. KAIST plans to expand the program to embrace the global community in earnest by establishing Education 3.0 Global in order to have interactive real-time classes for students and researchers across regions and cultures. President Kang will also present a paper entitled "Toward Socially Responsible Technology: KAIST"s Approach to Integrating Social and Behavioral Perspectives into Technology Development" at another session of GULF called "Seeking New Approaches to Critical Global Challenges." In the paper, President Kang points out that notwithstanding the many benefits we enjoy from the increasingly interconnected world, digital media may pose a threat to become a new outlet for social problems, for example, Internet or digital addiction. Experts say that early exposure to digital devices harms the healthy development of cognitive functions, emotions, and social behavior. President Kang will introduce KAIST"s recent endeavor to develop a non-intrusive technology to help prevent digital addiction, which will ultimately be embedded in the form of a virtual coach or mentor that helps and guides people under risk to make constructive use of digital devices. President Kang stresses the fundamental shift in the science and technology development paradigm from research and development (R&D) to a research and solution development (R&SD), taking serious consideration of societal needs, quality of life, and social impacts when conducting research. Professor Sang Yup Lee will moderate the IdeasLab session at the Davos Forum entitled "From Lab to Life with the California Institute of Technology (Caltech)." Together with scientists from Caltech, he will discuss scientific breakthroughs that transform institutions, industries, and individuals in the near future, such as the development of damage-tolerant lightweight materials with nanotechnology, the ability to read and write genomes, and wireless lab-in-the-body monitors. In addition, he will meet global business leaders at the session of "Sustainability, Innovation, and Growth" and speak about how emerging technologies, biotechnology in particular, will transform future societies, business, and industries. As a current special adviser of the World Economic Forum"s (WEF) Chemicals Industry Community, Professor Lee will meet global chairs and chief executive officers of chemical companies and discuss ways to advance the industry to become more bio-based and environmentally friendly. He served as a founding chairman of WEF"s Global Agenda Councils on Biotechnology in 2013. President Sung-Mo Steve Kang Distinguished Professor Sang Yup Lee

Mechanism in regulation of cancer-related key enzyme, ATM, for DNA damage and repair revealed
Professor Kwang-Wook Choi A research team led by Professor Kwang-Wook Choi and Dr. Seong-Tae Hong from the Department of Biological Sciences at KAIST has successfully investigated the operational mechanism of the protein Ataxia Telangiectasia Mutated (ATM), an essential protein to the function of a crucial key enzyme that repairs the damaged DNA which stores biometric information. The results were published on December 19th Nature Communications online edition. All organisms, including humans, constantly strive to protect the information within their DNA from damages posed by a number of factors, such as carbonized materials in our daily food intake, radioactive materials such as radon emitting from the cement of buildings or ultraviolet of the sunlight, which could be a trigger for cancer. In order to keep the DNA information safe, the organisms are always carrying out complex and sophisticated DNA repair work, which involves the crucial DNA damage repair protein ATM. Consequently, a faulty ATM leads to higher risks of cancer. Until now, academia predicted that the Translationally Controlled Tumor Protein (TCTP) will play an important role in regulating the function of ATM. However, since most of main research regarding TCTP has only been conducted in cultured cells, it was unable to identify exactly what mechanisms TCTP employs to control ATM. The KAIST research team identified that TCTP can combine with ATM or increase the enzymatic activity of ATM. In addition, Drosophilia, one of the most widely used model organisms for molecular genetics, has been used to identify that TCTP and ATM play a very important role in repairing the DNA damaged by radiation. This information has allowed the researchers to establish TCTP’s essential function in maintaining the DNA information in cell cultures and even in higher organisms, and to provide specific and important clues to the regulation of ATM by TCTP. Professor Kwang-Wook Choi said, “Our research is a good example that basic research using Drosophilia can make important contributions to understanding the process of diseases, such as cancer, and to developing adequate treatment.” The research has been funded by the Ministry of Science, ICT and Future Planning, Republic of Korea, and the National Research Foundation of Korea. Figure 1. When the amount of TCTP protein is reduced, cells of the Drosophila's eye are abnormally deformed by radiation. Scale bars = 200mm Figure 2. When the amount of TCTP protein is reduced, the chromosomes of Drosophilia are easily broken by radiation. Scale bars = 10 mm. Figure 3. When gene expressions of TCTP and ATM are reduced, large defects occur in the normal development of the eye. (Left: normal Drosophilia's eye, right: development-deficient eye) Figure 4. ATM marks the position of the broken DNA, with TCTP helping to facilitate this reaction. DNA (blue line) within the cell nucleus is coiled around the histone protein (green cylinder). When DNA is broken, ATM protein attaches a phosphate group (P). Multiple DNA repair protein recognizes the phosphate as a signal that requires repair and gathers at the site.
