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:

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.

Success in differentiating Functional Vascular Progenitor Cells (VPC)
KAIST’s Professor Han Yong Man successfully differentiated vascular progenitor cells from human embryonic stem cells and reversed differentiated stem cells.
The research went beyond the current method of synthesis of embryonic body or mice cell ball culture and used the careful alteration of signal transmission system of the human embryonic stem cells to differentiate the formation of vascular progenitor cells.
The team controlled the MEK/ERK and BMP signal transmission system that serves an important role in the self replication of human embryonic stem cells and successfully differentiated 20% of the cells experimented on to vascular progenitor cells.
The vascular progenitor cells produced with such a method successfully differentiated into cells forming the endodermis of the blood vessel, vascular smooth muscle cells and hematopoietic cells in an environment outside of the human body and also successfully differentiated into blood vessels in nude mice.
In addition, the vascular progenitor cell derived from human embryonic cells successfully formed blood vessels or secreted vascular growth factors and increased the blood flow and the necrosis of blood vessels when injected into an animal with limb ischemic illness.
The research was funded by the Ministry of Education, Science and Technology, 21st Century Frontier Research and Development Institution’s Cell Application Research Department and Professor Ko Kyu Young (KAIST), Professor Choi Chul Hee (KAIST), Professor Jeong Hyung Min (Cha Medical School) and Doctor Jo Lee Sook (Researcher in Korea Bio Engineering Institute) participated in it.
The results of the research was published as the cover paper of the September edition of “Blood (IF:10.55)”, the American Blood Journal and has been patented domestically and has finished registration of foreign PCT.
The results of the experiment opened the possibility of providing a patient specific cure using stem cells in the field of blood vessel illness.

The KAIST & GIT team developed a power generation technology using bendable thin film nano-materials.
Figure description: Flexible thin film nanomaterials produce electricity.
Can a heart implanted micro robot operate permanently?
Can cell phones and tiny robots implanted in the heart operate permanently without having their batteries charged?
It might sound like science fiction, but these things seem to be possible in the near future. The team of Prof. Keon Jae Lee (KAIST, Dept. of Materials Science and Engineering) and Prof. Zhong Lin Wang (Georgia Institute of Technology, Dept. of Materials Science and Engineering) has developed new forms of highly efficient, flexible nanogenerator technology using the freely bendable piezoelectric ceramic thin film nano-materials that can convert tiny movements of the human body (such as heart beats and blood flow) into electrical energy.
The piezoelectric effect refers to voltage generation when pressure or bending strength is applied to piezoelectric materials. The ceramics, containing a perovskite structure, have a high piezoelectric efficiency. Until now, it has been very difficult to use these ceramic materials to fabricate flexible electronic systems due to their brittle property.
The research team, however, has succeeded in developing a bio-eco-friendly ceramic thin film nanogenerator that is freely bendable without breakdown.
Nanogenerator technology, a power generating system without wires or batteries, combines nanotechnology with piezoelectrics that can be used not only in personal mobile electronics but also in bio-implantable sensors or as an energy source for micro robots. Energy sources in nature (wind, vibration, and sound) and biomechanical forces produced by the human body (heart beats, blood flow, and muscle contraction/relaxation) can infinitely produce nonpolluting energy. (Nanogenerator produces electricity by external forces: http://www.youtube.com/watch?v=tvj0SsBqpBw)
Prof. Keon Jae Lee (KAIST) was involved in the first co-invention of “High Performance Flexible Single Crystal Electronics” during his PhD course at the University of Illinois at Urbana-Champaign. This nanogenerator technology, based on the previous invention, utilized the similar protocol of transferring ceramic thin film nano-materials on flexible substrates and produced voltage generation between electrodes.
Prof. Zhong Lin Wang (Georgia Tech, inventor of the nanogenerator) said, “This technology can be used to turn on an LED by slightly modifying circuits and operate touchable flexible displays. In addition, thin film nano-materials (‘barium titanate’) of this research have the property of both high efficiency and lead-free bio compatibility, which can be used in future medical applications.” This result is published in November online issue of ‘Nano Letters’ ACS journal.

I believe that the discussion we will hold today at the forum will point to the future direction of research universities.”
“To produce next generation engineers meeting global standards, exchange and dual degree programs between universities must be strengthened,” said Lars Pallesen, President of the Technical University of Denmark. “Research universities must support the exchange between students beyond cultural and national borders to adapt to the global market.”
Ichiro Okura, Vice President of Tokyo Institute of Technology, presented on the “Asian Science and Technology Pioneering Institutes of Research and Education, ASPIRE.” ASPIRE is a community created by the coalition between science and technology universities in the Far East. Its purpose is to contribute to sustainable global growth by educating high-quality human resources and lead Asia’s technology innovation based on science and technology development.
“For research universities to solve today’s global issues, universities must create new ideas by performing fundamental studies and developing innovative technology. The financial resources of universities must be focused with choices based on results,” remarked President Suh.
Zaini Ujang, Vice-President of the Universiti Teknologi Malaysia stated that “the Malaysian government is planning on converting from a ‘labor-intensive economy’ to an ‘innovative leading economy’ with the goal of joining the advanced countries by 2020. In today’s science and technology era where innovative technology is necessary, research universities have an important role of developing the knowledge environmental system to lead the world economy.” Vice-President Ujang then explained what strategies Malaysian research universities devised in the innovative leading economy era to create research universities that bring creativity and innovation.
Tod A. Laursen, President of KUSTAR, said that “KUSTAR has a leading role in bringing science and technology and manpower necessary in converting the oil-centered economy of UAE to a knowledge-based economy. KUSTAR will continuously strengthen international cooperation to become not only the best engineering university in the Arab region but in the world.”

OLEV Safety Confirmed by International Standards
On September 19, KAIST announced that the electromagnetic (EM) field levels of its online electric vehicle (OLEV) measured in June and September of this year demonstrated verification of its safety.
Last June, the EM field level of OLEV installed at the Seoul Grand Park was measured by the Korea Research Institute of Standards and Science (KRISS) to test its harmfulness to human. The results were 0.5 ~ 61mG which is within the national and international standards of 62.5mG.
KRISS measured EM field levels on 22 spots on the side of and at the center of OLEV at a fixed distance (30cm) but variable heights (5cm~150cm) according to the national standard of measurement methods for electromagnetic fields of household appliances and similar apparatuses with regard to human exposure (IEC 62233).
In addition, another testing took place on September 13 following a request by National Assemblywoman Young-Ah Park, a member of the National Assembly’s Education, Science and Technology Committee, who has raised an issue on the safety of OLEV. This testing session was held by EMF Safety, Inc., an institution designated by Park, and it tested the EM field level of the same OLEV train that was tested in June.
As a result, the September measurements were well within the national and international standards with 0~24.1mG. The test was conducted under the presence of third party to produce a fair and objective result.
As reference, the EM field level results are well within the American IEEE electromagnetic field standards of 1,100 mG.
The September measurements were produced by Park’s recommendation of following the criteria specified in the measurement procedures of IEC 62110, “Electric and magnetic field levels generated by AC power systems to public exposure,” which were 15 measurements at a fixed 20cm distance at the side of and from the center of OLEV with variable heights of 50cm~150cm.
