International News Outlets Report on KAIST's On-Line Electric Vehicle Project
International news agencies such as the Associated Press and Reuters have recently reported on the "online" electric vehicle project KAIST is proceeding with. A number of newspapers abroad including the New York Times and the South China Morning Post of Hong Kong published the articles. Following are excerpts from those reports.

S. Koreans designing "online" electric vehicles
By JEAN H. LEE
Associated Press
Urban visionaries in London and Seoul, two of the world"s busiest capital cities, foresee buses gliding through their streets with speed, ease and efficiency _ without emitting the exhaust fumes that scientists say are contributing to global warming.Under Mayor Boris Johnson"s vision, London"s iconic red double-decker Routemaster buses would be back on the streets _ but powered by electricity, not gasoline.
Engineers at South Korea"s top-ranked KAIST university are meanwhile working on a novel prototype for an electric vehicle system: one that provides power on the go through induction strips laid into the roadway.
Cities _ which house 75 percent of the world"s population and generate 80 percent of its pollution _ must take leadership in tackling the problem of polluting emissions, Johnson said Monday in Seoul on the eve of the third C40 Large Cities Climate Summit.
"I think as a collective of cities, what we should be doing here in Seoul is agreeing that we are going to stop the endless addiction of mankind to the internal combustion engine," he told reporters. "It"s time that we moved away from fossil fuels. It"s time that we went for low-carbon vehicles."
"Cars form many problems that we see in Korea as well as other countries. We use hydrocarbon organic fuels, mostly petroleum, and that, in turn, creates environmental problems _ and Seoul is notorious," said Suh Nam-pyo, president of KAIST in Daejeon, south of the South Korean capital.
Seoul, population 10 million, is getting warmer three times faster than the world average, the National Meteorological Administration said Monday.
The obvious solution, Suh said, is to "replace all these vehicles with vehicles that do not pollute the air and do not use oil."
Back in March, Johnson zipped down a British highway in a U.S.-made electric car that he wrote marked "the beginning of a long-overdue revolution."
He rhapsodized in a Telegraph newspaper editorial that the Tesla has no exhaust pipe, carburetor or fuel tank, and "while every other car on that motorway was a-parping and a-puttering, filling the air with fumes and particulates, this car was producing no more noxious vapours than a dandelion in an alpine meadow."
Last month, he launched an ambitious plan to get 100,000 electric cars onto the streets of London by 2015. He pushed for the creation of 25,000 charging stations and vowed to convert some 1,000 city vehicles to make London the "electric car capital of Europe."
"The age of the diesel-emitting bus has got to be over in London," Johnson said.
And scientists are still grappling with the massive, sensitive, costly and fast-depleting batteries that take the place of international combustion engines and gasoline. Electric cars run between 40 and 120 miles (60 to 200 kilometers) on one charge, and it takes anywhere from two to seven hours to fully recharge, said Christian Mueller of the IHS Global Insight consulting firm.
"Everybody is frantically working on coming up with a viable electric car," he said from Frankfurt, Germany.
Batteries "aren"t yet at a state where we can say they are cheap, they"re reliable and they"re easy to come by. They all still have their technical drawbacks," said Mueller, who specializes in electrics and electronics.
Suh, an MIT-trained inventor with some 60 international patents to his name, approached the challenge from another angle.
"Why not have power transmitted on the ground and pick it up without using mechanical contact?" he said in an interview in his office overlooking the staging grounds for the university"s electric cars.
KAIST"s "online" vehicles pick up power from trips, or inverters, embedded into the road rather than transmitted through rails or overhead wires. A small battery, one-fifth the size of the bulky batteries typically used, would give the vehicle enough power for another 50 miles (80 kilometers), said Cho Dong-ho, the scientist in charge of the project.
South Korea produces its own nuclear power, meaning it can produce a continuous supply of energy to fuel such a plan.
President Lee Myung-bak, whose government gave KAIST $50 million for two major projects, including the "online" electric vehicle, took a spin in February.
Online buses are running at the KAIST campus and will begin test runs soon on the resort island of Jeju.
But Seoul, which has promised to set aside $2 million for the underground charging system, is within Suh"s sights. He said 9,000 gasoline-fueled buses now crisscross the capital, with 1,000 going out of commission each year. He envisions replacing those aging buses with electric models. Initial test runs are expected to take place this year.
Mueller, the consultant, called it a creative approach with potential.
"It sounds very intriguing; you don"t store your energy, you provide it on the go." he said. "The (battery) storage problem is overcome instantly. That would be a very intriguing way of doing it."

South Korea tries recharging road to power vehicles
By Jon Herskovitz
SEOUL (Reuters) - South Korea"s top technology university has developed a plan to power electric cars through recharging strips embedded in roadways that use a technology to transfer energy found in some electric toothbrushes.
The plan, still in the experimental stage, calls for placing power strips about 20 cm (8 inches) to 90 cm (35 inches) wide and perhaps several hundred meters long built into the top of roads.
Vehicles with sensor-driven magnetic devices on their underside can suck up energy as they travel over the strips without coming into direct contact.
"If we place these strips on about 10 percent of roadways in a city, we could power electric vehicles," said Cho Dong-ho, the manager of the "online electric vehicle" plan at the Korea Advanced Institute of Science and Technology.
The university has built a prototype at its campus in Daejeon, about 140 km (90 miles) south of Seoul, for electric-powered golf carts and is working on designs that would power cars and buses.
The system that can charge several vehicles at once would allow electric cars and buses to cut down on their battery sizes or extend their ranges.
The non-contact transfer of electricity, also called inductive charging, works by magnets and cables on the underside of the vehicle making a connection with the current in the recharging strip to receive power as they travel over it.
It is employed in some brands of electric toothbrushes that are sealed and water resistant, which do not need to be plugged into anything but use a magnetic connection to receive energy while resting in a cradle.
The recharging strips, which are attached to small electrical stations, would be laid in places such as bus lanes and the roads running up to intersections so that vehicles could power up where traffic slows down, Cho said.
The system will be tested later this year for use in the bus systems of Seoul and other South Korea cities while some of the country"s automakers are also cooperating in the project.
Unlike electric lines used for trams, vehicles do not need to be in constant contact with the strips and a person can touch the lines without receiving a shock.
The system so far has proven safe to humans and machinery, Cho said.
The cost of installing the system is an estimated 400 million won ($318,000) per kilometer of road. Electricity is extra.

KAIST Ranked Seventh in Chosun-QS 2009 Asian University Rankings
- Major Criteria in Research, Education, Globalization
KAIST ranked top in Korea and seventh in Asia in a ranking compiled jointly by the Chosun Ilbo, a major Korean daily, and global university evaluation institute QS of Britain.
In the rankings released on Tuesday (May 12), KAIST scored 94.9 based on the full 100 of the top-ranking university, the University of Hong Kong. KAIST was closely followed by Seoul National University (SNU), which ranked 8th in the Asian ranking. KAIST outpaced SNU in terms of globalization, but lagged behind in terms of peer review and recruiters review.
The Chosun Ilbo said that KAIST achieved the distinction by encouraging competition among research professors, introducing competitive educational systems such as conducting all classes in English, and speeding up globalization drive based on a strong leadership of President Nam-Pyo Suh.
In an interview with the daily published on the same day, President Nam-Pyo Suh expressed enthusiasm for stepping up his university"s drive to make it one of the world"s leading research universities, without resting on its present reputation. "The goal of KAIST is to stand at the forefront in addressing critical problems facing the humanity in the 21st century. The problems include alternative energies and transportation and logistics. If we resolve these problems, KAIST will join the ranks of the world"s best universities," Suh said.
The evaluation, the only such survey in Asia, was conducted with 463 universities in 11 countries, including 106 in Korea. The universities were ranked for competitiveness in four categories -- research quality (60 percent), teaching quality (20 percent), graduate employability (10 percent) and international outlook (10 percent).
The top-ranked University of Hong Kong was followed by Chinese University of Hong Kong, Tokyo University, Hong Kong University of Science and Technology, and Osaka University.
The top 100 Asian universities include 17 Korean universities, 33 Japanese, 11 Chinese, seven Indian, six in Hong Kong and two in Singapore.
Universities were ranked through a quantitative analysis based on data submitted by the universities in March and a qualitative analysis based on the competitiveness of professors and graduates evaluated by about 3,100 academics and businesspeople around the world.
Meanwhile, KAIST was ranked 95th among top 200 universities of the world in the Times Higher Education-QS World University rankings in 2008. It ranked 34th in the area of engineering and information technology, and 46th in natural science.

Prof. Chong Unveils New Human Movement Model
A KAIST research team headed by Prof. Song Chong of the School of Electrical Engineering and Computer Science has developed a new statistical model that simulates human mobility patterns, mimicking the way people move over the course of a day, a month or longer, university sources said on Tuesday (May 12).
The model, developed in collaboration with scientists at North Carolina State University, is the first to represent the regular movement patterns of humans using statistical data.
The model has a variety of potential uses, ranging from land use planning to public health studies on epidemic disease.
The researchers gave global positioning system (GPS) devices to approximately 100 volunteers at five locations in the U.S. and South Korea and tracked the participants" movements over time. By tracing the points where the study participants stopped, and their movement trajectories, researchers were able to determine patterns of mobility behavior.
The researchers were then able to emulate these fundamental statistical properties of human mobility into a model that could be used to represent the regular daily movement of humans. The model, called Self-similar Least Action Walk (SLAW), will have a wide array of practical applications.
The research, "SLAW: A Mobility Model for Human Walks," was presented on April 20 at the 28th IEEE Conference on Computer Communications in Rio de Janeiro, Brazil. The National Science Foundation of the U.S. funded the research.

KAIST Dedicates Geocentrifuge Experiment Center
KAIST dedicated the KOCED Geo-Centrifuge Experiment Center for researches in monitoring natural disasters such as earthquake and embankment collapse through miniature simulation tests on Wednesday (April 9) after a two-year construction work.
The experiment center is part of the Korea Construction Engineering Development Collaboratory Program (KOCED) which has been sponsored by the Ministry of Land, Transport and Maritime Affairs to build an infrastructure for construction engineering researches at a national level. The ministry plans to build a total of 5 similar centers nationwide by the end of the year.
On hand at the dedication ceremony were Jae-Choon Lee, President of the Korea Institute of Construction & Transportation Technology Evaluation and Planning, KAIST President Nam-Pyo Suh, and scores of experts and administration officials.
The construction of the five-story building on an area of about 3,328 square meters cost 8.4 billion won (US$6.3 million).
The center is expected to serve as a major laboratory in the field of geotechnical engineering. It is equipped with such state-of-the-art facilities as geocentrifuge, a useful tool for studying flow in unsaturated soil under well-controlled, repeatable conditions, a bidirectional shaking-table that can reproduce earthquake-like wave; and robots that can reproduce construction procedures by remote control.
Geocentrifuge experiment allows detecting ground and structure motions easily and rapidly by simulation tests. Thus, it is widely used for various geotechnical engineering researches such as evaluation of seismic safety, soft ground movement, slope stability analysis, etc. The causes of the embankment collapse in New Orleans by Hurricane Katrina in 2005 were also revealed by the geocentrifuge experiment.
The geocentrifuge research facility is available for use by outside researchers, so scientists from other universities, research institutes and corporations can perform research and test their scientific and engineering hypotheses.
The center is divided into two sections, experiment building and research building. The experiment building is composed of a geocentrifuge laboratory, model-making rooms, workshops, a geotechnical engineering laboratory and specimen storehouse, while the research building has a control room, a video conference room, an electronic library and research rooms.

KAIST to Admit 150 Students Based on Recommendations
KAIST will select 150 students from regular high schools, excluding those from special purpose schools, on the basis of their principals" recommendations and interview results beginning in the next school year in an effort to diversify admissions, President Nam-Pyo Suh said on Thursday (March 5).
Award-winning records at math or science competitions will not be put into account in admissions to prevent after-school tutoring aimed at winning such contests.
President Suh unveiled the new admission plan at a news conference in Seoul. "We expect the principals to recommend students with special talents or potential rather than high grades," Suh said. Established under a special law in 1971, KAIST is given full liberty to recruit freshmen students in whatever method it deems right, without being required to use the scholastic ability test scores of applicants as the basic criteria.
KAIST plans to initially select 1,000 students across the country based on recommendations. Admission officers will single out 300 for further review. Out of the 300, the final 150 students will be chosen through in-depth interviews.
"Years of receiving principal recommendations would accumulate a database on high schools nationwide. If a student recommended by a principal turns out to be no good, we might not pick more students from that school," President Suh said.
Over 80 percent of students admitted to KAIST this year were graduates of elite institutions, mostly science high schools. Only 20 percent came from regular high schools. The 150 additional openings next year will be allotted to only those attending ordinary high school.
Ten percent of the 150 openings will be assigned to students from rural areas and another 10 percent will go to students from low-income households.
"One high school was not able to send even a single student to KAIST for the last 10 years. I"m sure there are talented students in that school. If we give the school a chance, the education system will be upgraded," President Suh said.
KAIST-affiliated Korea Science Academy, a Busan-based high school for gifted students, will also adopt similar admission policy of recruiting students solely on the basis on recommendation and interview results from 2011.

Oriental Medical Scientist Lyu Awarded Honorary Doctorate Degree from KAIST
KAIST awarded an honorary doctorate degree to Keun-Chul Lyu, an Oriental medical scientist who donated property valued at 57.8 billion won (US$56 million) to KAIST at its 2009 commencement ceremony on Feb. 27.
Dr. Lyu who was born in Cheonan, South Chungcheong Province, in 1926 received the first-ever doctorate degree in Oriental medicine from Kyung Hee University in 1976. His researches and practices have had profound impact on Oriental medicine in Korea and elsewhere. He successfully administered acupuncture anesthesia for Caesarean section in 1972, for the first time outside China.
During the three years (1973-1975) he worked at the Kyung Hee University"s Apoplexy Center as superintendent, he developed a new cure incorporating the Oriental and Western medicines for patients seized with apoplexy. With a thesis based on the cure, he earned a Ph.D. in medical engineering from Moscow State Technical University Bauman in 1996.
His outstanding capabilities drew attention in the 1970s when he served as a professor of the Department of Acupuncture at Kyung Hee University and later as deputy director of the university"s Hospital of Oriental Medicine. His record of treating about 50,000 patients a year is still touted among the younger generation of Korean Oriental medicine practitioners.
Dr. Lyu"s unselfish spirit of public service has been well exhibited in that he actively engaged in rendering voluntary medical services in rural and medically disadvantaged areas. He also distinguished himself with his strong interest in donation for humanitarian causes. Among his many charitable activities, his donation of a multipurpose gymnasium and golf practice range to a primary school in his native town Cheonan made so many children happy and helped them develop great ambitions. In 2008, he donated property valued at 57.8 billion won (US$56 million) to KAIST, wishing to help broaden the academic horizon of students studying at Korea"s premier research university.
His donation to KAIST was the largest in amount in the history of private donations to universities in Korea.

Prof. Song Develops Nano-Structure to Enhance Power of Rechargeable Lithium-ion Battery
A team of scientists led by Prof. Hyun-Joon Song of the Department of Chemistry, KAIST, developed a nano-structure that could increase the power of rechargeable lithium-ion batteries, university sources said on Monday (Feb. 16).
The research team found that a nano-structured material using copper oxide (CuO) could produce lithium-ion batteries with some 50 percent more capacity than conventional products. The study was published in the online edition of peer-review journal Advanced Materials.
In rechargeable lithium-ion batteries, lithium ions move between the battery"s anode and cathode. The high-energy density of the batteries led to their common use in consumer electronics products, expecially portable devices. Their demand in automotive and aerospace applications is growing, and nano-structured, or nano-enabled batteries are emerging as the new generation of lithium-ion batteries for their edge in recharging time, capacity and battery life.
Graphite has been a popular material for cathodes in lithium-ion batteries. However, graphite cathodes are also blamed for lost capacity due to their consumption of lithium ions, which are linked to shorter battery life.
As such, scientists have been looking for materials that could replace graphite in cathodes, and silicon and metal oxide have been studied as possible alternatives.

KAIST Wins First Prize at Recon Challenge of Int"l Magnetic Resonance Society
Professor Jong-chul Ye of the Department of Bio and Brain Engineering and Hong Jeong, a doctorate student, won the first prize at the Recon Challenge held as part of a workshop sponsored by the International Society for Magnetic Resonance in Medicine (ISMRM) held in Sedona, the United States.
The workshop took place under the theme of “data sampling and image reconstruction” on Jan. 25-28 in Sedona, Arizona, the United States. The KAIST team beat out major magnetic resonance imaging groups from the U.S. and Europe.
The Recon Challenge is a biennial competition highlighting different reconstruction strategies and metrics to compare them. ISMRM is an international, nonprofit, scientific association which promotes communication, research, development, and applications in the field of magnetic resonance in medicine and biology and other related topics.
At the competition, the KAIST team presented a new dynamic MRI algorithm called k-t FOCUSS that is optimal from a compressed sensing perspective. The main contribution of the method is extension of k-t FOCUSS to a more general framework with prediction and residual encoding. The prediction provides an initial estimate while the residual encoding takes care of the remaining residual signals.
