The output of terahertz waves enhanced by KAIST team
KAIST researchers have greatly improved the output of terahertz waves, the blue ocean of the optics world. This technology is expected to be applied to portable X-ray cameras, small bio-diagnostic systems, and in many other devices. Professor Ki-Hun Jeong"s research team from the Department of Bio and Brain Engineering used optical nano-antenna technology to increase the output of terahertz waves by three times. Terahertz waves are electromagnetic waves with frequencies between 100GHz to 30THz. They are produced when a femtosecond (10^-15 s) pulse laser is shone on a semiconductor substrate with photoconduction antennas, causing a photocurrent pulse of one picosecond (10^-12 s). Their long wavelengths, in comparison to visible light and infrared rays, give terahertz waves a high penetration power with less energy than X-rays, making them less harmful to humans. These qualities allow us to see through objects, just as X-rays do, but because terahertz waves absorb certain frequencies, we can detect hidden explosives or drugs, which was not possible with X-rays. We can even identify fake drugs. Furthermore, using the spectral information, we can analyze a material"s innate qualities without chemical processing, making it possible to identify skin diseases without harming the body. However, the output was not sufficient to be used in biosensors and other applications. Prof. Jeong"s team added optical nano-antennas, made from gold nano-rods, in between the photoconduction antennas and optimized the structure. This resulted in nanoplasmonic resonance in the photoconduction substrate, increasing the degree of integration of the photocurrent pulse and resulting in a three times larger output. Hence, it is not only possible to see through objects more clearly, but it is also possible to analyze components without a biopsy. Professor Jeong explained, "This technology, coupled with the miniaturization of terahertz devices, can be applied to endoscopes to detect early epithelial cancer" and that he will focus on creating and commercializing these biosensor systems. This research was published in the March issue of the international nanotechnology journal ACS Nano and was funded by the Korea Evaluation Institute of Industrial Technology and the National Research Foundation of Korea.

City of McAllen, Texas Adopts OLEV Technology
KAIST will be exporting the OLEV technology to the United States for the first time since its development. The city of McAllen of Texas will be stationing 3 OLEV buses in the 10 mile (16km) route from 2013 from OLEV Technology Corporation. The OLEV Technology Corporation based in Massachusetts and is a venture company that KAIST has 30% share of and has the OLEV technology. The corporation has sole license in commercialization of OLEV in the United States. The OLEV technology has been commercialized in the city of Seoul since July of 2011. But this is the first instance of foreign implementation of the OLEV technology. The reason for the city of McAllen adopting the OLEV is because of the support of the Department of Transportation. The Department of Transportation has been supporting Green Energy Research and Future Transportation Technology Development projects since 2009. A total of 266 research proposals were submitted in 2011 and out of that 46 were selected and given a total of 112 million USD. Representative of McAllen city commented “the operation of OLEV buses developed by KAIST will result in decrease in energy consumption and emission of greenhouse gases. The OLEV technology can be applied to existing diesel buses and therefore has high cost efficiency”.
Fusion performing arts, called space musical, 'NARO' performed at KAIST
In commemoration of the 6th anniversary of the establishment of the Graduate School of Cultural Technology, KAIST organized an English musical show on space at the Auditorium on the 29th and 30th of September. The name of the musical was NARO. The musical was funded by the ‘NaDa Center’ operated by KAIST’s Graduate School of Cultural Technology. The musical was created with participation from adolescents, which told a tale about a genius boy Naro’s journey in space. The musical was composed of two parts, and the basic storyline was about Naro who conducts research based on space, and his friends went on a time travel to the constellation Scorpios; more specifically, it was a Korean traditional children’s story about a brother and sister who became the sun and the moon. Naro and his friends prevent the plot of Tyran, a villan, who plans on destroying the space and Earth by inducing a red giant star, Antares. In preparation for the musical, NaDa Center selected 14 students ranging from elementary to high school students during March of 2011. The selected students met every Saturday and Sunday from March to September for practice; a gargantuan commitment. The theme of the musical is space, the future, and hope, and it does not utilize any stage settings. Instead, it attempts the incorporation of high technology into the stage by using interactive video, laser art, and specially built props. In addition, the entire process from script to performance and advertisement was utilized as an education model to suggest a good fusion between science and technology and cultural arts. The musical ‘NARO’ is a collective effort. Professor Won Kwan Yeon who pioneered the field of Cultural Technology directed the musical, Professor Koo Bon Chul was in charge of the script and music composition, acting was charged to Lee Min Ho, choreography was charged to Han Eun Kyung, astrological reference was charged to Park Seok Jae among other students in the Graduate School of Cultural Technology. Members of the KAIST Acting Club ‘Lee Bak Teo’, Jeong Soo Han, Son Sharon and graduate of Chung Nam National University with vocal music major Yang Su Ji also made appearances. The Space Musical ‘NARO’ was funded by the Korea Astronomy and Space Science Institute, Korea Aerospace Research Institute, and LG School of Multi Culture.
KAIST Successfully Demonstrates Mobile Harbor in the Open Sea
Busan, South Korea—Large container ships are no longer required to come into ports to transport cargo, as KAIST has developed an innovative technology that will transform the paradigm of today’s cargo handling operations. A Mobile Harbor is a vessel that carries a large stabilized crane with a smart spreader and multistage trolley system, enabling the loading and unloading of ship cargo on the wavy open sea. Following a successful docking of two vessels at sea in April of this year, KAIST conducted a full scope of Mobile Harbor operations in the inner sea of Busan, South Korea, on June 29, 2011. Initiated in 2009, the Mobile Harbor (MH) is one of the university’s flagship research projects, which aims to provide a new growth engine that will lead the Korean economy to the next level of advancement, and to develop green technology through multidisciplinary and convergence research. The idea of MH came to light when thinking outside the box (why can’t a harbor go out to meet a ship on voyage and retrieve goods instead of ships coming into the harbor?) to improve problems relating to the current maritime transport system, such as port congestion, environmental issues caused by heavy sea transport, increased demand for supersized container ships, and the need for port construction and expansion. The essential technology to establish a Mobile Harbor is a docking system and crane system that can overcome the obstacles imposed by the sea, i.e., waves and wind. Connecting two operating vessels of different sizes in the unpredictable and ever-changing environment of the sea was regarded as “impossible” and had never been tried before, but, on April 26, 2011, KAIST successfully demonstrated the technology to moor vessels safely and securely. The Mobile Harbor has a unique way of mooring vessels that are anchored at sea: its flexibly designed robot arms with a square-shape vacuum suction pad at the tip reach out and attach to the hull of a container ship for docking. Each robot arm is connected to a cable and winch that further add stability to the Mobile Harbor. Foam-filled fenders are placed between the Mobile Harbor and the container ship, thereby maintaining a safe distance to prevent collisions. The crane system consists of a multistage trolley, smart spreader, and tension controller, all of which provide the crane with functionality and stability to move around cargo containers in the sea. The crane system also has various sensors like cameras and laser scanners, and therefore, it can gauge the movement of the spreader and ships as well as trace a target container in real time. As a result, the spreader, a container grabbing device, is free from the swing motions when lifting and putting down cargo and grabs a target container safely in the wavy open sea. During today’s at-sea demonstration in Busan, a research team from the KAIST Mobile Harbor Center docked a Mobile Harbor (a barge ship) right next to a container vessel (the other barge ship) and repeated freight transport operations between the two ships, presenting the great potential to commercialize the Mobile Harbor technology. The project has been implemented in collaboration with industries, research institutes, and universities in such fields as mechanical engineering, robotics, automation engineering, and ocean systems engineering. The demonstration proceeded with a wide range of participants including researchers, engineers, government officials, and entrepreneurs from Korea and around the world. Byung-Man Kwak, Director of the KAIST Mobile Harbor Center, explained his feelings on the successful demonstration: “It’s been a remarkable journey to develop a Mobile Harbor from scratch, and I’m genuinely thrilled to showcase what we have accomplished so far. Today’s demonstration of Mobile Harbor’s core technologies will really change the face of our maritime transportation system. We will be able to deliver more goods to global markets and consumers via sea route, not necessarily building more ports or expanding the existing harbors. KAIST’s Mobile Harbor will also significantly cut down the high cost related to overland transportation of cargo and in return, contribute to the reduction of carbon emission.” The Center has received much interest in possible market migration and broader application of the Mobile Harbor from businesses and organizations, e.g., US Office of Naval Research, King Fahd University of Petroleum and Minerals, Saudi Aramco, POSCO, and the Korean Navy.

Businessweek: How Twitter Could Unleash World Peace, April 11, 2011
A KAIST graduate scholar, Meeyoung Cha, conducted a joint study with international researchers and released a paper on the aspect of twitter as an emerging cyber arena for political and social debates and discussions. An article on the paper from Businessweek follows: Businessweek April 11, 2011, 9:08PM EST text size: TT How Twitter Could Unleash World Peace Researchers from Britain, Korea, and Germany have determined that the amount of fresh information you get on Twitter is less a matter of what you follow than whom—and who follows you By Bobbie Johnson On certain days, Twitter can feel like the world"s biggest, fastest echo chamber. Since we tend to follow people who are similar to us, we often see our own views reflected back—meaning a gloomy cloud of irritation can rapidly swirl into a cyclone of outrage as we hear from other people who feel as we do. A group of computer scientists have discovered that the opposite may also be true. Can Twitter be part of the solution, not merely part of the problem? In a study to be presented at a conference in July, a team of researchers from the U.K."s University of Cambridge, Korea"s Graduate School of cultural Technology-KAIST, and Germany"s Max Planck Institute for Software Systems show how Twitter can provide users greater access to more varied political viewpoints and media sources than they might otherwise get. The paper, called "The Media Landscape in Twitter(http://www.cl.cam.ac.uk/~jac22/out/twitter-diverse.pdf)," explains how the team made surprising discoveries when they looked into the site"s usage patterns. First they looked at who follows whom and discovered that Twitter is a highly politicized space. Then they examined patterns of tweeting and retweeting to try to understand how people receive information on Twitter—and what they might see. Their conclusion: Although Twitter is a pretty partisan space, it can offer unprecedented opportunities to break down the barriers that plague local, national, and international politics. How? Through retweets and interaction—what the authors call "indirect media exposure." As they put it, this "expands the political diversity of news to which users are exposed to a surprising extent, increasing the range by between 60 percent and 98 percent. These results are valuable because they have not been readily available to traditional media and they can help predict how we will read news and how publishers will interact with us in the future." If you"re interested in the way Twitter works, I recommend reading the paper, which isn"t very long. Meanwhile, let"s boil it down to a few key pieces of data and see what lessons they can teach. Most Twitter users are political. Just over half (50.8 percent) of all Twitter users studied showed a distinct political bias in the media outlets and individuals they followed. Most of those lean to the left of the political spectrum, accounting for 62 percent of users who demonstrated some bias. Thirty-seven percent were doggedly centrist. Just 1 percent of Twitter users who showed a political preference were right-wing. Here are a couple of caveats about reading too much into the sharp divide the authors found. Given that Twitter"s user base is younger and more metropolitan than the societal norm, it"s not surprising that it"s weighted to the left. It"s worth noting that this study was undertaken more than a year ago; since then, Twitter has grown dramatically, while global politics have largely skewed back toward the right. Twitter"s user base today might reflect a more-balanced political picture. Either way, there"s a big split. Twitter has secondary and tertiary benefits. Most organizations comprehend Twitter in simple terms: More followers means more exposure. But the study shows that it"s not just about those you follow, but those your followers follow—essentially the people in your extended network. The network offers a number of routes for information from fresh sources to get to you. According to the study, some 80 percent of users choose to follow at least 10 media sources, but they are exposed to between 6 and 10 times as many media sources through their friends. People outweigh brands. Many of the biggest Twitter accounts are big media brands such as CNN (TWX) and Time, but the study suggests that Twitter"s active users tend to prefer individuals over outlets. So while the average follower of @NYTimes (NYT) has six followers apiece, individual journalists have followers who boast a median following count of around 100. That gives individual journalists—who are, the study says, more likely to link to a multiplicity of sources—a much wider, more influential network of connections. The inference is that the personal touch of a journalist is more important than the lofty, impersonal tone of publications that largely act as promotion channels for their content. It"s a discovery that reminded me of Twitter"s recent blog post on the science of the hashtag, which found that hashtags explode in usage when they are picked up by individuals with the most dedicated—not necessarily the largest—followings. Active users access a wider range of views. The researchers say that indirect exposure expands political diversity by a "significant amount," despite other studies showing a tendency for social networks to do the opposite. "Other studies have found a stronger tendency of homophily; blogs of different political views rarely linked to each other," they point out. "One possible reason is that a Twitter network encompasses several different relationships—from shared interest, to familial ties, friends, and acquaintances—so political similarity doesn"t necessarily exist in all such ties." This is not to say that Twitter"s creators should be preparing a Nobel Prize-winning speech. Far from it: The influence of its diversity is unknown. It could be that many people who see messages they disagree with simply change their behavior to screen out such material in future. But it shows that there is a potential to do something positive at Twitter. It"s clear there"s much work to be done. The researchers say they want to investigate a number of areas they"ve uncovered, having provided important insights at a time when politics seem more fractious and divided than ever.
2011 Wearable Computer Competition Participant Registration Started
The registration process for the ‘Wearable Computer Contest’ (WCC) held by KAST and Korea Next Generation Computing Institute. The contest is the only contest that designs wearable computers in Korea. This year’s theme is ‘Smart Wear for the Smart Life’ in response to the spread of smartphones. In 2010 the contest was run cooperatively with International Symposium on Wearable Computer (ISWC) and is fast becoming an international even with students from foreign universities attending. The participants will be putting forth an idea on wearable computers that have IT and fashion fused into it and actually produces such an outfit. The cost of producing a prototype will be provided by the holders and education of basics needed in producing a prototype like ubiquitous computing, wearable computer platform, human-computer interface, fashion and design. The restriction of theme was taken out of the equation and in its place, an idea tank involving handing in ideas in poster format was put into place. In addition the competition is no longer limited to undergraduates or graduate students. Detailed information on registration and of the contest itself can be found at www.ufcom.org .
