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.

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.

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.

Rechargeable Lithium Sulfur Battery for Greater Battery Capacity
Professor Do Kyung Kim from the Department of Material Science and Engineering and Professor Jang Wook Choi from the Graduate School of EEWS have been featured in the lead story of the renowned nanoscience journal Advanced Materials for their research on the lithium sulfur battery. This new type of battery developed by Professor Kim is expected to have a longer life battery life and [higher] energy density than currently commercial batteries.
With ample energy density up to 2100Wh/kg—almost 5.4 times that of lithium ion batteries—lithium sulfur batteries can withstand the sharp decrease in energy capacity resulting from charging and discharging—which has been considered the inherent limitation of the conventional batteries.
Professor Kim and his research team used one-dimensional, vertical alignment of 75nm tick, 15μm long sulfur nanowires to maximize electric conductivity. Then, to prevent loss of battery life, they carbon-coated each nanowire and prohibited direct contact between the sulfur and electrolyte.
The result was one of the most powerful batteries in terms of both energy performance and density. Compared to conventional batteries which suffer from continuous decrease in energy capacity after being discharged, the lithium sulfur battery maintained 99.2% of its initial capacity after being charged and discharged 300 times and up to 70% even after 1000 times.
Professor Kim claims that his new battery is an important step forward towards a high-performance rechargeable battery which is a vital technology for unmanned vehicles, electric automobiles and energy storage. He hopes that his research can solve the problems of battery-capacity loss and contribute to South Korea’s leading position in battery technology. Professor Kim’s research team has filed applications for one domestic and international patent for their research.

Wearable computer follows suit of smart phones
KAIST hosts “Wearable Computer Competition” in KI Building, Daejeon Campus, on the 7th-8th of November
“Computer that controls smart phones with the movement of facial muscles” and 12 other wearable computers to be presented
As technology transitions to “Wearable Computers,” KAIST is hosting its 9th “Wearable Computer Competition.” The competition will take place over two days, 7th-8th of November, in KI building, on the main Daejeon Campus.
The “wearable computer” is designed to enable users to use the computer whilst moving by limiting its weight and size so that it can be worn as a part of the body and clothing. Wearable computers have been considered the future of information technology (IT) ever since smart phones and other miniaturized IT devices made an appearance.
The “Wearable Computer Competition” has been held since 2005 under the leadership of Professor Hoi-Jun Yoo from the KAIST Department of Electrical Engineering. It is the only competition in the nation where undergraduate students use their unique ideas and newest technology to produce computers that seem to be existed only in sci-fi movies and comic books.
A total of 15 teams out of 70 made the competition and went through a rigorous selection process based on written applications and interviews to enter the final. The teams at the final received USD 1,400 and IT devices including smart phones to produce a wearable computer.
KAIST increased the number of finalists from the last year"s 10 to 15 this year as the wearable computer industry is extending, and there is growing interest in the computer around the world after the launch of Google Glass and Samsung Galaxy Gear.
This year’s entries included a product for quadriplegic patients to control smart phones with the movement of facial muscles, which attracted public interest. The product in the form of a headband can be worn by quadriplegic patients or someone with limited hand movement. The user can activate the product by clenching their molars and move the mouse on the smart phones with the movement of muscles in their face.
Furthermore, a wearable band shaped device that can control smart phones with simple hand movements is also attracting interest. Broad hand movements of the user allows him/her to receive calls and take photos, and handshakes between users control sharing of files. Body communication can be used to protect private information without a password or locking the device.
In addition, gloves and shoes that can sense the user’s movement to play an instrument without the instrument being present; a cane for the blind that converts visual information to tactile; a belt that protects children from sexual crimes; and a game where the user can be Super Mario to play and other practical products are presented.
The chairman of the competition, Professor Yoo said, “As you can see from the launch of Samsung Galaxy Gear, wearable computers will follow smart phones as the leader of IT devices in the next generation.” He continued, “This competition and workshop is an opportunity to increase public interest in wearable computers and serves as a communication platform for experts to view the present and the future of wearable computers.”
The “Wearable Computer Workshop” will be held this year as well. The workshop under the theme of “the present and the future of wearable computers” invited Professor Kyu-Ho Park, Vice President of KAIST, as a keynote speaker to talk on “ubiquitous, fashionable computers.” Moreover, Samsung’s Dong-Jun Geum and the Electronics and Telecommunications Research Institute’s Hyeon-Tae Jeong will lecture on the “trend and direction of progress of wearable devices” and the “technological trend and prospect of industry of wearable computers,” respectively.
