KAIST Top in the Nature Publishing Index 2013 Asia-Pacific
The Nature Publishing Index 2013 Asia-Pacific has been released today. The index is a supplement to Nature, which measures the output of research articles from nations and institutes published in the 18 Nature-branded primary research journals over the calendar year. A press release from the Nature Publishing Group follows below: South Korea regains scientific impetus PRESS RELEASE FROM NATURE PUBLISHING GROUP Embargoed until 03.00 KST on Thursday 27 March 2014 South Korea ranks fourth for scientific research output in the region, according to the Nature Publishing Index 2013 Asia-Pacific released today. In 2013, the nation significantly increased its NPI output following a slight drop in 2012. Named a possible ‘one to watch’ by the supplement editors, with high levels of investment in science and technology announced by both government and private enterprise, its NPI output is growing faster than China’s. The Korea Advanced Institute of Science and Technology has risen two places to take top spot above Seoul National University, which has retained second place. Pohang University of Science and Technology has leapt from eighth to third, with a more-than-threefold increase in corrected count, adjusted for the proportional contribution of collaborative institutions. Last year’s number one, Yonsei University, could not maintain its exceptional 2012 NPI output and has dropped to seventh spot. It is now just above a newcomer, the Institute for Basic Science (IBS), funded as part of the government’s increased investment in basic science. IBS plans to open 50 research centres by 2017 and will no doubt provide increasing contributions in the next few years. To see the latest results for the region, and the Nature Publishing Index Global Top 100, visit the Index website at www.natureasia.com/en/publishing-index.

Visit by Sir Paul Maxime Nurse, President of the Royal Society
Sir Paul Maxime Nurse, who is an English geneticist and cell biologist, visited KAIST and gave a lecture entitled The Great Ideas of Biology on March 11, 2014. Sir Paul was awarded the 2001 Nobel Prize in Physiology or Medicine with Leland H. Hartwell and R. Timothy Hunt for their discoveries of protein molecules that control the division of cells in the cell cycle. He was Professor of Microbiology at the University of Oxford, CEO of the Imperial Cancer Research Fund and Cancer Research UK, and President of Rockefeller University in New York. Sir Paul is currently the President of the Royal Society as well as Director and Chief Executive of the Francis Crick Institute. Founded in London in 1660, the Royal Society is composed of the world’s most distinguished scientists drawn from all areas of science, engineering, and medicine. Below is a summary of his lecture, The Great Ideas of Biology: Four major ideas of biology are the theory of genes, evolution by natural selection, the proposal that the cell is the fundamental unit of all life, and the chemical composition of a cell. When considering the question “what is life?” these ideas come together. The special way cells reproduce provides the conditions by which natural selection takes place, allowing living organisms to evolve. The organization of chemistry within the cell provides explanations for life’s phenomena. In addition, an emerging idea is the nature of biological self-organization with which living cells and organisms process information and acquire specific forms. These great ideas have influenced one another and changed the way we perceive biology and science today.

Welcoming the Class of 2014
“The four years from today will go quickly, and I urge you to make the most of your time in KAIST, a great educational and research institution where you will explore the frontiers of science and technology and take part in the creation of new knowledge,” President Kang told the freshmen at the convocation ceremony. Freshmen Convocation for the Class of 2014 took place on March 3, 2014 at the auditorium on the main campus. Members of the KAIST community, along with hundreds of parents and guests, welcomed the incoming 800 freshmen, celebrating the beginning of their four-year college life. Kwang-Joon Ahn, a graduate of the Korea Science Academy, and Ha-Rim Jin, a graduate of Daegu Il Science High School, were representatives of the incoming students, and they took the “Class of 2014 Pledge,” a commitment to uphold KAIST’s core values, which is "creativity and challenge (endeavoring spirit)," and to pursue intellectual passion and discovery. President Steve Kang delivered congratulatory remarks, encouraging students to use their opportunities to the fullest while at KAIST to broaden their knowledge and experience. He also stressed the following four important principles they should cultivate to become the leaders of tomorrow: be grateful, excel in their field, keep open minds about what the globalized world would bring, and never give up on their dreams and belief. President Kang said: “Probably, many of you, the graduates of the best high schools in Korea, will find KAIST a tougher place to be in than you imagined. But challenges, particularly intellectual challenges, should be viewed as an opportunity to grow. It is ok to fail. In fact, without risking failures, there won’t be a meaningful growth because the real growth comes from overcoming challenges.” “You can’t avoid failing in the course of your college life, but your perseverance to do it over will allow you to develop the skills and passion needed to become a leader who will contribute to the local community, as well as to the betterment of humanity.” The KAIST Alumni Scholarship Foundation presented a scholarship of USD 3,700 to 24 freshmen. The convocation ended with music performances by members of the student clubs at KAIST.

Spillover Phenomenon Identified Using Model Catalyst System
Researchers at KAIST have identified spillover phenomenon, which has remained controversial since its discovery in the early 1960s. KAIST Department of Chemical and Biomolecular Engineering’s Professor Min-Gi Choi and his team has explained the "spillover phenomenon," using their own model catalyst system where platinum is selectively located within the amorphous aluminosilicate. The research results were published on the 25th February online edition of Nature Communications. Spillover refers to a phenomenon that occurs when hydrogen atoms that have been activated on the surface of metals, such as platinum, move to the surface of the catalyst. It was predicted that this phenomenon can be used to design a catalyst with high activity and stability, and thus has been actively studied over the last 50 years. However, many cases of the known catalysts involved competing reactions on the exposed metal surface, which made it impossible to directly identify the presence and formation mechanism of spillover. The catalysts developed by the researchers at KAIST used platinum nanoparticles covered with aluminosilicate. This only allowed the hydrogen molecules to pass through and has effectively blocked the competing reactions, enabling the research team to study the spillover phenomenon. Through various catalyst structure and reactivity analysis, as well as computer modeling, the team has discovered that Brönsted acid sites present on the aluminosilicate plays a crucial role in spillover phenomenon. In addition, the spillover-based hydrogenation catalyst proposed by the research team showed very high hydrogenation and dehydrogenation activity. The ability of the catalyst to significantly inhibit unwanted hydrogenolysis reaction during the petrochemical processes also suggested a large industrial potential. Professor Min-Gi Choi said, “This particular catalyst, which can trigger the reaction only by spillover phenomenon, can be properly designed to exceed the capacity of the conventional metal catalysts. The future goal is to make a catalyst with much higher activity and selectivity.” The research was conducted through funds subsidized by SK Innovation and Ministry of Science, ICT and Future Planning. The senior research fellow of SK Innovation Seung-Hun Oh said, “SK Innovation will continue to develop a new commercial catalyst based on the technology from this research.” Juh-Wan Lim and Hye-Yeong Shin led the research as joint first authors under supervision of Professor Min-Gi Choi and computer modeling works were conducted by KAIST EEWS (environment, energy, water, and sustainability) graduate school’s Professor Hyeong-Jun Kim.

Quacquarelli Symonds (QS) World University Rankings by Subject 2014
The QS World University Rankings are annual university rankings published by Quacquarelli Symonds (QS) which provides the overall rankings of top global universities as well as the rankings for individual subjects. The 2014 QS World University Rankings by Subject is a comprehensive guide to the world’s best universities in 30 popular subjects of 5 academic disciplines: arts & humanities, engineering & technology, life sciences & medicine, natural sciences, and social sciences. According to the 2014 subject rankings, released on February 26, KAIST made the list of top 50 universities in 9 subjects: physics & astronomy; materials sciences; chemistry; chemical engineering; mechanical, aeronautical & manufacturing engineering; electrical & electronic engineering; civil & structural engineering; computer science & information systems; and biological sciences. Among them, KAIST was ranked number one in Korea for 5 subjects: materials sciences (16th); mechanical, aeronautical & manufacturing engineering (21st); civil & structural engineering (32nd); computer science & information systems (36th), and biological sciences (43rd). For basic sciences, KAIST has made good progress as well. For example, in mathematics, KAIST took first place in Korea and was ranked in the 51st-100th of the world’s top universities. Another notable result was that its business college in Seoul campus, a relatively new addition to KAIST, made the rankings list of 51st-100th in accounting & finance. The 2014 QS subject rankings used the following criteria for its evaluation of university performance: a survey of academic and employer reputation, citations per paper, inclusion of specialists, and the h-index, known as the Hirsch index or Hirsch number, which was suggested by Jorge E. Hirsch, a physicist at the University of California in San Diego, as a tool for determining theoretical physicists’ relative quality. Today, the h-index is used to measure both the productivity and impact of the published work of a scientist or scholar.

A game enthusiast received a Ph.D. at the 2014 commencement
A high school student, who was addicted to video gaming and had barely managed to gain entrance to KAIST, became a star of its 2014 commencement ceremony. The student was Tae-Woo Park who received his Ph.D. in games at 32 years of age. Park entered KAIST in 2002 as an undergraduate student. However, owning to bad grades, he was not accepted to the graduate school of KAIST until 2006. He began playing games at the age of 7, which distracted him from his studies at an early age. Nevertheless, he was able to complete master’s degree after two and a half years, which normally takes two years for average students. Professor Joon-Hwa Song saw a possibility from his student’s experience of producing and commercializing a mobile puzzle game while Park was working as a president of the game club, HAJE, at KAIST. Professor Song advised him to take the advantage of his interests and try developing game platforms and contents. Park decided to develop a game that could help others and would change people’s negative views of games. He created a whole new generation of games. In order to find ideas for games that can be easily enjoyed in daily lives, Park went to numerous gyms, swimming pools, daycare centers, and parks to analyze people’s behaviors and discussed with his colleagues who were also interested in games. During this process, the experience of organizing creative ideas through cooperation and discussions became a great foundation for his future research. He observed some people quitting midway during a workout on treadmills because they were bored with working out alone. From this, Park embarked on developing a new style of game that allowed people to exercise together. Park used the system on a treadmill, which recognizes the speed of the person running to automatically adjust the machine’s speed, to develop an interactive game platform for Swan Boat. The Swan Boat game is a race exercise game that adjusts the direction according to speed difference between two players. The game utilizes the difference of running speed between two people on treadmills to change the direction of the boat. With the Swan Boat game, people can now play games and exercise at the same time. The technology also allows online access anywhere in the world, which means checking friends’ rankings at nearby gyms or homes, or even a World Gym Running Contest. In addition, Park helped develop various next generation exercise games and life-based services, including the sparrow chirp application, which finds children that go astray, or an avatar game that utilizes the user’s daily life patterns. These results and papers attracted attention from international societies and have also won a number of awards. Professor Song said, “There has been no precedent of receiving a Ph.D. at KAIST for developing games, however, Park’s case has given courage to many people that if you can create what is really required in everyday life, you can indeed receive a doctor’s degree.” Park remarked, “I’d like to express my gratitude to my advisor, Professor Song, for giving me courage. I want to continue to make games that can help people’s lives in the future.” Park will continue his work at the NASA Ames Research Center this June.

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

Is it possible to identify rumors on SNS?
Rumors sporadically spread with people with fewer followers in the centerResearched over 100 rumors in the US from 2006 to 2009 Is it possible to filter information on SNS such as Twitter and Facebook? A research team led by Professor Mee-Young Cha from the Department of Cultural Technology Graduate School at KAIST, Professor Kyo-Min Jung of Seoul National University, Doctor Wei Chen and Yajun Wang of Microsoft Asia, has developed a technology that can accurately filter out information on Twitter to 90% accuracy. The research not only deduced a new mathematical model, network structure, and linguistic characteristics on rumors from SNS data, but is also expected to enhance the effort to make secure technology to regulate Internet rumors. The team analysed the characteristics of rumors in over 100 widespread cases in the US from 2006 to 2009 on Twitter. The team gathered data, which included a range of areas such as politics, IT, health and celebrity gossips, and their analysis could identify rumors to 90% accuracy. The filtering was more accurate in rumors that included slanders or insults. The research team identified three characteristics of the spread of rumors. Firstly, rumors spread continuously. Normal news spreads widely once and is mentioned rarely again on media, but rumors tend to continue for years. Secondly, rumors spread through sporadic participation of random users with no connections. Rumors start from people with fewer followers and spread to the more popular. This phenomenon is often observed in rumors concerning celebrities or politicians. Lastly, rumors have unique linguistic characteristics. Rumors frequently include words (such as “it may be true,” “although not certain, I think,” “although I cannot fully remember”) related to psychological processes that question, deny, or infer the reliability of the information. Professor Cha said, “This research deduced not only a statistical and mathematical model but also is an integrated research on social psychological theory on the characteristics of rumors that attract great attention from the society based on ample data.” The results were made public in IEEE International Conference on Data Mining last December in Texas, USA.

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.
