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.

Actress Han Makes Donation to KAIST
Actress and movie star Han Eunjung donated 100 million won ($98,000) to KAIST to help Korea"s prestigious research-oriented university continue its academic development on Wednesday (June 4).
In a donation ceremony held at the KAIST President"s office, she signed an agreement for donation.
Han said that she came to realize the importance of science and technology while filming a new movie based on a 15th century Joseon Dynasty episode featuring the development of a rocket-like firearm called "Singijeon." The blockbuster movie will be released in early August.
She also said that she was impressed by the first Korean astronaut So-Yeon Lee who took her undergraduate, master"s and doctorate degrees at KAIST, and decided to make a contribution to the school.
"I hope that I would be of any help in the development of KAIST in becoming one of the top research universities in the world," she said.
Han has been cast for the MBC drama "Lawyers of Korea" which will be aired starting from July.

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.

KAIST to Build Branch Campus in New Administrative City
KAIST signed a memorandum of understanding (MOU) with the Multifunctional Administrative City Construction Agency and the Korea Land Corporation on March 4 to build a branch campus in the city now under construction to house many government organizations to be relocated from Seoul.
The MOU calls for building a well-facilitated KAIST campus on 310,000 square meters of land within the planned city, about 30 kilometers west of Daejeon. The multifunctional city, named Sejong City, is scheduled to be dedicated in 2014.
The MAC now being built in the Yongi-Gongju area of South Chungcheong Province is geographically in the center of South Korea, and many governmental agencies and major public organizations will move in from 2015.
The KAIST campus is envisioned to be home to a newly established College of Strategy and Policy, a Strategy and Policy Research Center, and an Innovative Technology Research Center. The College of Medical Science currently based in the Daejeon campus will be relocated to the campus. With a research-oriented hospital and a medical engineering research center, KAIST hopes to become a leading institution in disease treatment and medical engineering technologies.
The new campus is also expected to house new KAIST colleges now in the planning stage which will offer interdisciplinary courses such as the College of IT and Contents and the College of Life Sciences. KAIST also seeks to resolve housing shortage problems by building an in-campus village designed to provide international living environment for professors and students on the planned campus

Women Leaders Awarded Honorary Degrees
Korea"s two women leaders, Park Geun-hye, former President of the Grand National Party, and Lee Gil-ya, chairperson of the Gachon Gil Foundation, a major medical services organization, were awarded honorary doctorate degrees by KAIST, Korea"s state-run science and technology research university, on Feb. 29.
It is the first time in the school"s 37-year history that women have been awarded honorary doctorate degrees. Park and Lee were conferred with the honor during the university"s 2008 graduation ceremony in recognition of their achievements in social services.
KAIST President Suh Nam-pyo said that the university decided to confer honorary doctorate degrees to Park and Lee, who both have educational backgrounds in the fields of engineering and science, in order to present role models to female students in science and engineering who still make up a relatively small percentage of the total enrollment at KAIST and throughout Korean universities.
"Our graduates and future students will strive to make meaningful contributions to the nation and the world, just as the two women leaders have done so well, for so many years," said Suh in his commencement address.
Female students constitute 23 percent of the total enrollment of 7,800, including graduate and doctorate students.
The honorary doctorate citation said Park Geun-hye, a graduate of the Department of Electronic Engineering, Sogang University in Seoul, has exerted strenuous efforts for the advancement of science and technology education and women"s social role. Among other things, Park called for the launching of a "second-stage science and technology revolution" during her 2007 presidential campaign. She declared science and technology as "the most crucial area of national development and survival" and instituted seven-point strategies to innovate the nation"s science and technology. Those strategies are specifically aimed at increasing investment in science and technology, fostering a world-class science and technology university and creating science-friendly curriculum at schools.
Lee Gil-ya, a widely-revered medical doctor, has demonstrated outstanding leadership in education, culture, journalism and business management, according to her citation. Throughout her brilliant professional career, she has vigorously pursued her lifelong goal of philanthropy, social service and patriotism. In particular, her dedication to nurturing young talents is widely recognized in Korea.
