Board Chairman Chung Makes First Visit to Building Named After Him
Moon-Soul Chung, chairman of the KAIST board of trustees, visited the building built with his donation on Monday (Oct. 19) for the first time since he made the deed of gift eight years ago, university authorities said on Monday (Oct. 19). In 2000, Chung, founder and former CEO of Mirae Corp, manufacturer of semiconductor testing equipment, announced retirement and handed over the presidency of his company to one of his managing directors. One year later in 2001, he donated 30 billion won, then equivalent to $30 million, to KAIST. It was by then the largest amount given by a single donor. The major part of his donation went to constructing a building for the newly-established Department of Bio and Brain Engineering, and it was named after him. However, Chung did not attend the ground-breaking and dedication ceremonies, saying that he would not enter the building until KAIST achieved a breakthrough technology which can inject a hope to Koreans. On his first visit to the building, he was briefed on the major research outcomes of the department over the past seven years, which were highlighted by the recent invention of an apparatus for measuring perfusion rate of legs. A KAIST team headed by Prof. Chul-Hee Choi invented a light leakage prevention unit including a light emitting device for radiating light having a certain wavelength onto a living body injected with Indocyanine Green (ICG). According to Prof. Choi, the invention relates to an apparatus for measuring the perfusion rate of legs. The invention also includes a light leakage prevention housing formed to prevent transmission of external light. Chung expressing satisfaction with the achievements and encouraged professors, researchers and students working at the Moon-Soul Chung Building.

Bae's Design Team Wins Good Design Award
An eco-friendly pot humidifier designed by a KAIST team led by Prof. Sang-Min Bae of the Department of Industrial Design won the G-Mark award at the 2009 Good Design Award, university authorities said on Tuesday (Sept. 29). The Good Design Award is a Japanese comprehensive design evaluation and commendation system operated by the Japan Industrial Design Promotion Organization (JIDPO). It originated from the Good Design Selection system, known as the "G-Mark System," instituted by the Ministry of International Trade and Industry of Japan in 1957. More than 1,000 companies and designers from 50-odd countries submit about 3,000 entries for consideration for the Good Design Awards each year. The humidifier controls the indoor humidity by natural vaporization using the tissue ball. The tissue ball is made of honeycomb shaped felt so that it can enhance water absorbing ability with large surface. In the package of the pot, there is a bottle of aroma liquid and people can use it for the fragrances as well as humidification. The pot, called "Love Pot," was designed for the Nanum (Sharing) Project, a charity activity to establish funds for donations through new products development. International aid organization World Vision, oil company GS Caltex and Prof. Bae"s ID+IM design laboratory have teamed up for the project. The KAIST team worked for free to design the pot. Profits from the sale of the pots were donated for education programs for low-income households. Among the products made under the Nanum Project was a cross cube MP3 player which won the silver prize at the 2008 International Design Excellence Awards (IDEA). IDEA is one of the world"s top three design awards along with Germany"s International Forum DEsign Awards and the Red Dot Design Awards. Prof. Bae"s team also won the "Best of the Best" award at Red Dot last November with the "Roly Poly Pot," a planter that tips to the side when the plant is thirsty.

Prof. Lee"s Team Pioneers Biotechnological Production of Chemical Using Renewable Materials
A research team led by Prof. Sang-Yup Lee of the Bio and Brain Engineering Department at KAIST has succeeded in engineering the bacterium E. coli to produce the industrial chemical putrescine, university authorities said on Monday (Aug. 31). Putrescine, a four carbon chain diamine, is an important platform chemical with a wide range of applications for the pharmaceutical, agrochemical and chemical industries. It is currently used to synthesize nylon-4,6, a widely used engineering plastic. The research result, published in the Biotechnology and Bioengineering journal, proviDrdes a renewable alternative to the traditional process using fossil fuels. Currently the production of putrescine on an industrial scale relies on chemical synthesis, which requires non-renewable petrochemicals and expensive catalyst systems. This process is highly toxic and flammable with potentially severe repercussions for both the environment and human health. "For the first time we have developed a metabolically engineered E. coli strain that efficiently produces putrescine," said Professor Lee. "The development of a bio-refinery for chemicals and materials is very important in a world where dependency on fossil fuels is an increasing concern." The team developed a strain of E.coli capable of producing putrescine through metabolic engineering. This is where a cell"s metabolic and regulatory networks are enhanced in order to increase production of a needed material. First the team weakened or deleted competing metabolic pathways within the E. coli strain before deleting pathways which cause putrescine degradation. They also amplified the crucial enzyme Spec C, which converts the chemical ornithine into putrescine. Finally the putrescine exporter, which allows excretion of intracellularly made putrescine, was engineered while a global regulator was engineered to further increase the concentration of putrescine. The final result of this process was an engineered E.coli strain which produced 24.2 g of putrescine per litre. However, as it was believed that putrescine is toxic to microorganisms the team had to study putrescine tolerance in E.coli before it could be engineered to overproduce the chemical to the levels needed for industrial production. The results revealed that E. coli can tolerate at least 0.5 M of putrescine, which is tenfold higher than the usual concentration in the cell. This level of tolerance was an important surprise as it means that E. coli can be engineered to overproduce putrescine to industrially competitive levels. "The previously expected toxicity of putrescine may explain why its microbial production has been overlooked," said Lee. "Now a metabolically engineered E. coli strain has been developed which is capable of efficiently producing putrescine using renewable methods to an industrial level. This metabolic engineering framework should be useful for developing metabolically engineered microorganisms for the efficient production of other chemicals from renewable resources," he added.

Prof. Choi Unveils Method to Improve Emission Efficiency of OLED
A KAIST research team led by Prof. Kyung-Cheol Choi of the School of Electrical Engineering & Computer Science discovered the surface plasmon-enhanced spontaneous emission based on an organic light-emitting device (OLED), a finding expected to improve OLED"s emission efficiency, KAIST authorities said on Thursday (July 9). For surface plasmon localization, silver nanoparticles were thermally deposited in a high vacuum on cathode. Since plasmons provide a strong oscillator decay channel, time-resolved photoluninescene (PL) results displayed a 1.75-fold increased emission rate, and continuous wave PL results showed a twofold enhanced intensity. "The method using surface plasmon represents a new technology to enhance the emission efficiency of OLED. It is expected to greatly contribute to the development of new technologies in OLED and flexible display, as well as securing original technology," Prof. Choi said. The finding was published in the April issue of Applied Physics Letters and the June 25 issue of Optics Express. It will be also featured as the research highlight of the August issue of Nature Photonics and Virtual Journal of Ultrafast Science.

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 Research Team Discovers Process for Rapid Growth of N-Doped CNT Arrays
A team of scientists led by Profs. Sang-Ouk Kim, Won-Jong Lee and Duck-Hyun Lee of the Department of Materials Science and Engineering has found a straightforward process for rapid growth of wall-number selected, nitrogen-doped carbon nanotube (CNT) arrays, university officials said on Monday (March 16). KAIST researchers prepared highly uniform nanopatterned iron catalyst arrays by tilted deposition through block copolymer nanotemplates. This remarkably fast growth of highly uniform N-doped CNTs, whose material properties and chemical functionalizability are reinforced by N-doping, offers a new area of a large-scale nanofabrication, potentially useful for diverse nano-devices. Carbon nanotubes (CNTs) are of broad technical interest in electronics, photonics, energy devices, and other applications. However, establishing a straightforward process for mass production of uniform CNTs with desired structure and properties has been a long-standing challenge. In particular, it was strongly desired to precisely control the numbers of walls and diameter of CNTs, which are decisive parameters for the physical properties of CNTs. In this respect, the preparation of monodisperse catalyst array having a narrow size distribution is generally considered an effective pathway to produce well-defined CNTs, since the number of walls and diameter of the produced CNTs are closely related to the catalyst size. The finding was featured in the March 13 edition of Nano Letters, a leading journal in the nano technology field.
