New System to Generate Extreme-Ultraviolet Light Developed
A KAIST research team led by Prof. Seung-Woo Kim of the Mechanical Engineering Department developed a new system for generating coherent extreme-ultraviolet (EUV) light, school authorities announced on June 5.
The new system comes in a metallic nano-structure consisting of a two-dimensional array of gold "bow tie" elements on a sapphire plate. The new process was featured in the British journal Nature on June 5.
The properties of coherent EUV light make it a prime candidate for exciting technological applications. But, at present, the equipment needed to generate the short-wavelength light is costly and bulky. The system developed by Prof. Kim"s research team is expected to reduce both cost and bulk.
The new system uses the conventional principle of high-harmonic generation via the interaction of a femtosecond laser pulse with a gas, but adopts the novel concept of amplifying light by way of local plasmon field enhancement, according to the research team.

KAIST, GS Caltex Jointly Develop New Bacteria to Produce Biobutanol
KAIST and GS Caltex, Korea"s second-largest refiner, have jointly developed a new strain of bacteria to produce biobutanol, which is regarded as a promising next-generation biofuel, KAIST authorities said on Monday (June 2).
A research team led by Prof. Sang-Yup Lee of the Chemical and Biomolecular Engineering Department and researchers of GS Caltex succeeded in developing an improved strain of bacteria which enables to produce a large amount of biobutanol in the process of fermenting biomass. The research team has applied for international patent for the new technology.
Biomass refers to living and recently dead biological material that can be used as fuel or for industrial production. It usually refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for production of fibers, chemicals or heat.
In the 1970s and 1980s when scientists began researching the possibilities of alternative fuels, bacteria were used in the process of fermenting biomass. This ABE (acetone, butanol, ethanol) fermentation process yields butanol, acetone, and ethanol in a ratio of 6:3:1, respectively. Acetone produced in this process is not usable.
The newly developed technology to produce biobutanol has an advantage of lowering production cost by eliminating the process to separate acetone from butanol. This has been made possible by improving the bacteria used for the fermentation in metabolic engineering terms, and producing butanol and ethanol only in a ratio of 6:1, while curbing the generation of acetone.
In comparison with bioethanol, also a biofuel mixture which is currently under widespread use in some countries, butanol is more easily transported with gasoline and diesel through pipelines because of its lower tendency to separate from the fuel when contaminated with water. Butanol is also less corrosive than ethanol, another reason its transport through pipeline is preferable.
Global interest in full utilization of biomass and development of other alternative energy including biobutanol has deepened in recent years, as crude oil prices have skyrocketed to record levels and climate changes resulting from the excessive use of fossil fuel have been causing various problems around the world.

2008 Commencement Ceremony Held
The 2008 KAIST Commencement Ceremony was held on Feb. 29 at the KAIST Amphitheater in the presence of KAIST President Nam Pyo Suh, U.S. Ambassador to Korea Alexander Vershbow, alumni representatives and parents.
Other dignitaries on hand included National Assemblymen Sang-Kee Suh, Chang-Sun Hong and Sang-Min Lee; and Daejoen City Major Sung-Hyo Park.
President Suh and Vice President Soon-Heung Chang presented degrees to each of the 1,321 graduates (200 doctors, 725 masters and 396 bachelors) instead of just to representatives. Since its inception in 1971, KAIST has produced 7,067 Ph.D. graduates, 18,636 master"s degree holders and 8,998 bachelor"s degree holders. This year, 40 percent of the Ph.D. graduates, 79, were in their twenties upon graduation.
President Suh called on the graduates to return the favor they received from society by making their share of contributions to humanity. "You were chosen to be students of this unique university because the Korean people -- not only KAIST professors and staff, but also ordinary taxpayers -- believe that outstanding young people like you can change the world in which we live for the better. Now it is time for you to pay back their support," he said.
Notable graduates of this year include So-Yeon Yi, 29, the first Korean female astronaut candidate, who earned her doctorate degree in bio and brain engineering. She was granted a special award in recognition of her role in advancing space science in Korea but she could not attend the graduation ceremony due to her training schedule in Russia which will continue until April.
Eun-Gyu Oh, 26, was the youngest doctorate recipient in the ceremony and Won Hye-jeong, 21, recorded the top undergraduate GPA with a score of 4.20 over 4.3. Civil and environmental engineering major Seung-Hee Park, 28, published a total of eight papers in major international journals while attending KAIST and two more papers are currently under review.
So-Yeon Yi said: ``I frequently stayed up all night to research and write the paper. It was tough experience for me. Thanks to ceaseless support from professors and colleagues, however, I was able to complete the task,"" she said. ``I have done my best in studying, exercising and so on. I"m sure that my active, participatory attitude brought about this honorable moment.""
She is now training at Gagarin Cosmonaut Training Center near Moscow as a replacement astronaut in case Koh San, 31, who is to be the first Korean astronaut, is unable to go into orbit.
Koh and Yi were selected from more than 36,000 applicants last year. Koh was finally picked as the primary candidate last September. The two are serving as space ambassadors appointed by the Ministry of Science & Technology.

South Korean science prepares to take on the world
By Choe Sang-Hun
Friday, January 18, 2008
DAEJEON, South Korea: In Professor Cho Dong Ho"s laboratory at Kaist, South Korea"s top science and technology university, researchers are trying to develop technology that could let you fold a notebook-size electronic display and carry it in your pocket like a handkerchief.
It"s too early to say when something like this might be commercially available. But the experiment has already achieved one important breakthrough: it has mobilized professors from eight departments to collaborate on an idea proposed by a student.
This arrangement is almost unheard of in South Korea, where the norm is for a senior professor to dictate research projects to his own cloistered team. But it"s only one change afoot at this government-financed university, which has ambitions to transform the culture of South Korean science, and more.
"When we first got the student"s idea on what a future display should look like, we thought it was crazy, stuff from science fiction," said Cho, director of Kaist"s Institute for Information Technology Convergence. "But under our new president, we are being urged to try things no one else is likely to."
That university president is Suh Nam Pyo, 71, a mechanical engineer who used to be an administrator at the Massachusetts Institute of Technology and who is spearheading closely watched changes that are expected to have ramifications far beyond this campus 90 minutes by car south of Seoul.
His moves so far, from requiring professors to teach in English to basing student admissions on factors other than test scores, are aimed at making the university, and by extension South Korean society, much more competitive on a world scale.
When the South Korean government hired Suh in 2006 to shake up the state-financed Korean Advanced Institute of Science and Technology (which formally changed its name to its acronym, Kaist, on Jan. 1) the country"s leading schools faced a crisis. The old system, which guaranteed free tuition to lure promising students into science and technology, the drivers of South Korea"s industrial growth, was no longer working as well as it used to.
Prosperity was allowing those young people to choose fields of study once viewed as luxuries, like literature and history. Worse, increasing numbers were choosing to study abroad, mostly in the United States, and then not returning home. The fear was that South Korean institutions and enterprises would be gutted of expertise.
That concern was voiced at a news conference Monday by the president-elect, Lee Myung Bak, who said the educational system "isn"t producing talent that can compete globally."
Kaist, which was established in 1971 with foreign aid, has a special place in South Korean education. The military strongman Park Chung Hee recruited the brightest young people to train there as scientists and engineers. Villagers put up a large banner to celebrate whenever a local child was admitted.
"When I was a student here in the mid-1980s, some students stopped before the national flag at the library in the morning and observed a moment of silence, vowing to dedicate ourselves to the nation"s industrial development," said Cho Byung Jin, a professor of electrical engineering.
Since his arrival, Suh has become the most talked-about campus reformer in South Korea by taking on some of Kaist"s most hallowed traditions.
In a first for a Korean university, Suh has insisted that all classes eventually be taught in English, starting with those aimed at freshmen.
"I want Kaist students to work all over the world," Suh said last week. "I don"t want them to be like other Koreans who attend international conferences and have a lunch among themselves because they are afraid of speaking in English."
The move to English supports another of his changes: opening undergraduate degree programs to talented non-Koreans. Last year Kaist filled 51 of its 700 admission slots with foreign students on full scholarships. Meanwhile, he has ended free tuition for all; any student whose grade average falls below a B must pay up to $16,000 a year.
"My dream is to make Kaist a globalized university, one of the best universities in the world," he said.
In what may have been his most daring move, the university denied tenure to 15 of the 35 professors who applied last September. Until then, few if any applicants had failed tenure review in the university"s 36-year history.
In this education-obsessed country, Suh"s actions have been watched intensely for their broader impact. More than 82 percent of all high school graduates go on to higher education. What university a South Korean attends in his 20s can determine his position and salary in his 50s, a factor behind recent expos?of prominent South Koreans who faked prestigious diplomas.
The system is widely deplored but seldom challenged. From kindergarten, a child"s life is shaped largely by a single goal: doing well in examinations, particularly the all-important national college entrance exam. High school students plod through rote learning from dawn to dusk. Tutoring by "exam doctors" is a multibillion-dollar industry. During vacations, students attend private cram schools, which numbered 33,000 in 2006.
One result is a disciplined and conformist work force, an advantage when South Korea rapidly industrialized by copying technology from others. But now, with the country trying to climb the innovation ladder, the rigid school system is proving a stumbling block.
The nation"s highly hierarchical ways are often cited to explain how Hwang Woo Suk, the disgraced South Korean scientist who claimed he had produced stems cells from a cloned human embryo, could fabricate research findings with the complicity of junior associates.
The ambitious head overseas. Last year, 62,392 South Korean students were enrolled in U.S. colleges and universities, making them the third-largest foreign student group, after Indians (83,833) and Chinese (67,723), according to the U.S. Institute of International Education.
Some start earlier. About 35,000 South Korean children below college age go abroad each year, most to the United States to learn English.
Against this backdrop, Kaist has been experimenting with test-free admissions. For this year"s class, it brought applicants in for interviews and debates and make presentations while professors looked for creativity and leadership.
"About 20 percent of the students who formerly would have won admission didn"t make it under our new guidelines," Suh said. "We are looking for rough diamonds."
Challenging the status quo can be risky.
The Science and Technology Ministry, which oversees Kaist, had first looked outside South Korea for someone to lead the changes, choosing the Nobel physics laureate Robert Laughlin, who became the first foreigner to head a South Korean university in 2004. But he returned to Stanford University within two years, after the faculty rebelled against him for attempting some of the same changes Suh has instituted, accusing him, among other things, of insensitivity to Korean ways.
Suh"s Korean roots and experience shield him from such charges. He did not emigrate to the United States until he was 18 and has worked at Korean universities as well as serving as assistant director at the U.S. National Science Foundation in the 1980s and head of MIT"s department of mechanical engineering from 1991 to 2001.
"Reform entails sacrifices, but even if we don"t reform, there will be sacrifices," Suh said. "The difference is that if we don"t reform and don"t encourage competition, it"s the best people who are sacrificed."
So far, Suh"s innovations have mostly received favorable reviews.
Education Minister Kim Shi Il called them a "very desirable way of making Korea"s universities more competitive globally." The newspaper JoongAng Daily (which publishes an English-language version in partnership with the IHT) praised him for "smashing the iron rice bowls" (ending guaranteed job security) for professors and said, "We must learn from Kaist."
Ewan Stewart, a British physicist who has taught at Kaist since 1999, said, "Many of the things President Suh is saying were things I felt should have been said a long time ago."
Chung Joo Yeon, a first-year student, said she accepted the need for classes in English, but complained that some professors had no experience teaching in the language.
But Cho, the electrical engineering professor, said: "It"s no longer a matter of choice. If we want to maintain our school"s standards, we must draw talents from countries around the world, and that means we must conduct our classes in English."
Meanwhile, Lee has promised that as president he will give universities more autonomy by taking the "government"s hands off" how they select their students.

Three Professors Selected as IEEE Fellows
Three Korea Advanced Institute of Science and Technology (KAIST)’s professors, Ju-Jang Lee, Yong-Hee Lee, and Hoi-Jun Yoo, were selected as a part of the 2008 Institute of Electrical and Electronics Engineers, Inc (IEEE)’s “Fellows.” A Fellow is the highest level of membership given only to those “with an extraordinary record of accomplishments” in their field of study. Although some IEEE memberships can be gained freely by all, the Fellow status is bestowed only by the IEEE Board of Directors.
Professor Ju-Jang Lee was awarded the Fellow status “for contributions to intelligent robust control and robotics.” Robust control is a system’s stable maintenance under many inputs in a dynamic environment. A part of KAIST’s Electrical Engineering Department, Professor Ju-Jang Lee has conducted successful research in these fields, and has published 538 papers. He also holds many patents in and outside of the country, and is the General Chair for two upcoming IEEE conferences in 2008 and 2009.
Professor Yong-Hee Lee of KAIST’s Physics Department was recognized for his “contributions to photonic devices based upon vertical cavity surface emitting lasers and photonic crystals.” Photonic devices are those that allow the practical use of photons, and photon crystals are structures that affect the motion of photons. Professor Yong-Hee Lee is an expert in the field of Photonics and his works have been cited over 2500 times. He is also an outstanding speaker, giving over 30 lectures in front of international audiences in the past 5 years, and receiving The Distinguished Lecturer’s Award from IEEE.
Professor Hoi-Jun Yoo was granted the prestigious Fellow status for his “contributions to low-power and high-speed VLSI design.” VLSI stands for ‘very large scale integration’ and refers to the skill for packing a huge number of semiconductors on an integrated circuit. Professor Lee’s Fellow status is noteworthy in that he studied, worked, and researched solely in Korea. He is also the youngest of the three KAIST professors to be granted membership in the class of 2008 Fellowship. IEEE also recognized Professor Yoo as the most frequent publisher during the past 8 years.
IEEE, originally concentrating on Electric Engineering, has now branched into many related fields. It is a nonprofit organization, and its aim is to be the world"s leading professional association for the advancement of technology. For its Fellow Class of 2008, 295 members were chosen; which is less that 0.1% of their total members.By KAIST Herald on December, 2007
