The Korea Herald: [Editorial] Gambler’s donation
2010-05-18 18:09
KAIST, Korea’s leading research university, often makes news with donations from a variety of benefactors who wish to help develop science and technology in Korea with money they earned through their careers. The list of donors, which includes farmers, securities dealers, medical doctors, foreign businesspeople and popular entertainers, now has one unusual entry, a gambler.
Ahn Seung-pil, 60, may not be exactly a “gambler” – at least not a professional one. He has visited Kangwon Land, a casino located in the mountain region of Jeongseon, Gangwon Province, only a few times since it opened in 2000 as the only place Korean nationals could gamble. Ahn, who runs a small textile business in Seoul, hit the jackpot of 766 million won (about $665,000), the largest amount ever at Kangwon Land or from any slot machine at a Korean casino.
He said he was motivated to donate the money to KAIST in Daejeon City when he watched a television program after returning home, in which a professor emphasized the importance of advancing science and technology in the country. He had incurred heavy debts during the 1997 economic crisis and has yet to clear them all, but he thought of using the prize money for a good cause. The TV program guided him to KAIST, said Ahn, who has “not had a high level of education.”
Korea is known worldwide for its people’s strong zeal for university education. Parents do whatever they can to send their children to good universities but are so exhausted before the entrance that they barely pay the tuition once they get there. Universities have to rely mainly on tuition and meager subsidies from foundations or the state treasury. Private donations are rare, compared to European or American universities.
Major universities complain that members of the alumni societies are rather indifferent to calls for donation. The majority of donors who give significant amounts are people who weren’t lucky enough to go to university, such as Ahn Seung-pil.

1,180 meters of fence on campus facing Gap-Chun River will be gone by June 2010.
KAIST and the City of Daejeon have taken on a project to remove a stretch of fence on campus that faces Gap-Chun River, making the campus accessible to all citizens and visitors. The work will last for three months beginning on April 5th and throughout June 2010. Gradually, KAIST plans to remove the entire fence surrounding the campus within a few years.
The city government has encouraged government and public organizations in Daejeon to open up their public space to citizens and visitors as part of its initiatives to reach out to local communities. As of December 2008, seven public organizations have completed to rid of their boundary markers, and eight more organizations will make their gardens and campus available to the public by the end of this year.
All the expenses related to the removal of the fence will be borne by the city government. At the place where the fence is knocked down will become a park so that neighbors and visitors can come and rest.
A school official said, “This is an important campaign for us because it promotes more exchanges between the university and local community. Our campus has rich green foliage, and visitors will surely enjoy it. By opening up our campus to the public, we hope to return to the society what we have received as a public institution and create a forum where art, science, and technology meet together.”
In addition to the removal of the fence, KAIST and the city government will install flowerbeds, health facilities, and walking trails for the citizens.

Professor Eun-Seong Kim and his research staff observed the phenomena of hysteresis and relaxation dynamics from supersolid Helium
Professor Eun-Seong Kim and his research staff observed the phenomena of hysteresis and relaxation dynamics from supersolid Helium.
Their research paper was published in Nature Physics for the issue of April 2010.
If we take Helium 4 and cool it down at temperatures below 2.176 Kelivin, liquid helium 4 undergoes a phase transition and becomes superfluid with a zero viscosity. The superfluidity was observed in solid helium through an experiment performed by researchers of Pennsylvania State University in 2004. One of the researchers then was Professor Eun-Seong Kim in the Department of Physics, KAIST.
Professor Kim and his research staff, Hyung-Soon Choi, Ph.D., recently published their research results in Nature Physics (April 2010), a highly esteemed journal in the field, on the phenomena of hysteresis and relaxation dynamics observed in supersolid Helium.

Naro space rocket getting ready for second launch
By Bae Hyun-jung (tellme@heraldm.com)
The Ministry of Education, Science and Technology is checking on the second launch of Naro, Korea’s first space rocket, as all the necessary parts were transferred to the launch center last week.
The Science Technology Satellite No. 2 was transferred last Thursday from the KAIST Satellite Technology Research Center in Daejeon to the Naro Space Center in South Jeolla Province, said ministry officials.
The solid-fuel second-stage rocket reached the center last Monday and the liquid-fuel first-stage rocket did so on March 23. The latter was manufactured in Russia’s Khrunichev State Space Science and Production Center.
The satellite, a small one weighing 100 kilograms, was co-developed by the Korea Aerospace Research Institute, KAIST SaTReC and the Gwangju Institute of Science and Technology.
It is to revolve around the Earth for two years collecting data on climate change by gauging the hydrogen content in the atmosphere, said officials.
“With all the crucial parts ready here in the center, we have officially kicked off our final investigation before setting the details of the second Naro launch,” said a ministry official.
Second Vice Minister Kim Joong-hyun last week visited the Naro center to attend the overall inspection on all facilities related to the rocket launch.
The date has not yet been set for the second launch but will be fixed within this month, said officials.
With the general inspection completed on the facilities, the first-stage rocket and the satellite will be assembled and the combination will be joined by the second-stage rocket in May.
The first launching attempt ended in failure in August due to faulty electrical wiring or a mechanical problem in the fairing separation mechanism, according to panels.
The two fairings -- used to cover and protect the satellite placed on top of the Naro -- failed to separate timely and thus stopped the satellite from gaining sufficient velocity to reach its planned orbit.
Korea has so far spent 502.4 billion won ($428.1 million) on the Naro project since it began in August 2002.

"The 2010 Artificial Intelligence Robot War Competition" begins to receive applications
[Event Notice]
“The 2010 Artificial Intelligence Robot War Competition” begins to receive applications
A good opportunity to gauge the intelligence of your robots
“The 2010 Artificial Intelligence (AI) Robot War Competition” will be held in October 2010, and the Competition has been receiving applications from contestants since April 1st. The deadline for the application will be May 31st, 2010.
Qualified contestants must be a minimum of two, but less than six, team members, and they will compete in one of the two fields: System on Chip (SoC) Taekwon Robot and Humanoid Robot (HURO). Winners will be decided based on the intelligence capabilities presented by a robot’s platform that mimics key functions of the human brain.
SoC Taekwon Robot will compete against one another by using a camera installed on its head to recognize visual images, locations, distances, and gestures of the other competing robot.
HURO competition is a new entry begun this year, and winners will be determined in accordance with the robot’s ability to perform given missions and fights. Missions are to go through a track installed with obstacles, recognize colors and shapes of barriers, and knock down barriers to earn scores. Fighting will be performed in the form of a Korean martial art, Tae-kwon-do.
The Korean government has nominated Robotics as one of the key growth engines to develop IT industry and Korean economy. Robotics converge many of different engineering fields, such as machinery, materials, components, and embedded software. In particular, the SoC is an essential technology for Korea to continuously take lead in the semi-conductor industry in the world, which is an important element for robotics.
SoC stands for System on Chip, an integrated chip that assembles various chips and components to be fabricated together on a single chip, instead of building them on a circuit board. The SoC technology has advantages of higher performance, smaller space requirements, lower memory requirements, higher system reliability, and lower consumer costs.
An artificial intelligence SoC robot is autonomous because it can adapt itself to changes in various environments and reach a given goal without constantly receiving external orders.

New drug targeting method for microbial pathogens developed using in silico cell
A ripple effect is expected on the new antibacterial discovery using “in silico” cells
Featured as a journal cover paper of Molecular BioSystems
A research team of Distinguished Professor Sang Yup Lee at KAIST recently constructed an in silico cell of a microbial pathogen that is resistant to antibiotics and developed a new drug targeting method that could effectively disrupt the pathogen"s growth using the in silico cell.
Hyun Uk Kim, a graduate research assistant at the Department of Chemical and Biomolecular Engineering, KAIST, conducted this study as a part of his thesis research, and the study was featured as a journal cover paper in the February issue of Molecular BioSystems this year, published by The Royal Society of Chemistry based in Europe.
It was relatively easy to treat infectious microbes using antibiotics in the past. However, the overdose of antibiotics has caused pathogens to increase their resistance to various antibiotics, and it has become more difficult to cure infectious diseases these days.
A representative microbial pathogen is Acinetobacter baumannaii. Originally isolated from soils and water, this microorganism did not have resistance to antibiotics, and hence it was easy to eradicate them if infected. However, within a decade, this miroorganism has transformed into a dreadful super-bacterium resistant to antibiotics and caused many casualties among the U.S. and French soldiers who were injured from the recent Iraqi war and infected with Acinetobacter baumannaii.
Professor Lee’s group constructed an in silico cell of this A. baumannii by computationally collecting, integrating, and analyzing the biological information of the bacterium, scattered over various databases and literatures, in order to study this organism"s genomic features and system-wide metabolic characteristics. Furthermore, they employed this in silico cell for integrative approaches, including several network analysis and analysis of essential reactions and metabolites, to predict drug targets that effectively disrupt the pathogen"s growth. Final drug targets are the ones that selectively kill pathogens without harming human body.
Here, essential reactions refer to enzymatic reactions required for normal metabolic functioning in organisms, while essential metabolites indicate chemical compounds required in the metabolism for proper functioning, and their removal brings about the effect of simultaneously disrupting their associated enzymes that interact with them.
This study attempted to predict highly reliable drug targets by systematically scanning biological components, including metabolic genes, enzymatic reactions, that constitute an in silico cell in a short period of time.
This research achievement is highly regarded as it, for the first time, systematically scanned essential metabolites for the effective drug targets using the concept of systems biology, and paved the way for a new antibacterial discovery. This study is also expected to contribute to elucidating the infectious mechanism caused by pathogens.
"Although tons of genomic information is poured in at this moment, application research that efficiently converts this preliminary information into actually useful information is still lagged behind. In this regard, this study is meaningful in that medically useful information is generated from the genomic information of Acinetobacter baumannii," says Professor Lee. "In particular, development of this organism"s in silico cell allows generation of new knowledge regarding essential genes and enzymatic reactions under specific conditions," he added.
This study was supported by the Korean Systems Biology Project of the Ministry of Education, Science and Technology, and the patent for the development of in silico cells of microbial pathogens and drug targeting methods has been filed.

New Text Book on Chemistry Published by KAIST Professor and Student
A chemistry textbook written in English and Korean will aid Korean students to learn General Chemistry in a global academic setting.
Korean students majoring in chemistry and looking for an opportunity to study abroad will have a new, handy textbook that presents them with a practical introduction to an English speaking lecture on general chemistry.
Aiming for advanced Korean high school and college/university students, the inter-language textbook is written by two incumbent professors teaching chemistry at a university in Korea and the US. The book will help Korean students prepare for a classroom where various topics of general chemistry are presented and discussed in English. Clear, collated sections of English and Korean text provide the student with sufficient explanation of the rudimentary topics and concepts.
Composed of 15 chapters on the core subjects of General Chemistry, i.e., Stoichiometry and Chemical Reactions, Thermochemistry, Atomic Structure, and Bonding, the textbook includes essential English vocabulary and usage sections for each chapter; it also contains a pre-reading study guide on the subject that prepares the student for listening to a lecture. This section includes view-graph type slides, audio files, and follow-up questions the student can use to prepare for an English-speaking course. The various accompanying audio files are prepared to expose the student to English scientific dialogue and serve as examples for instruction at Korean secondary and tertiary schools.
The book was coauthored by Korean and American scientists: A father and son, who have taught chemistry at an American and Korean university, wrote the book. Professor Melvyn R. Churchill at the State University of New York at Buffalo and Professor David G. Churchill at KAIST prepared all of the technical English text which was adapted from General Chemistry course lecture notes; the text was further shaped by original perspectives arising from many student interactions and questions.
This English text was translated into Korean by Professor Kwanhee Lee from the Department of Life and Food Science at Handong Global University, who coauthored a previous preparatory book for Korean students in a different subject. He also supplied an important introductory section which serves as a general guide to the classroom student. Kibong Kim, a doctoral student in the Department of Chemistry at KAIST, helped in preparing the book as well.
“This has been definitely a collaborative undertaking with an international academic crew and it underscores that the Korean internationalization in science is mainstream. Professors and a Korean student created a new book for Korean consumption and benefit,” Professor David G. Churchill says.

Photonic crystals allow the fabrication of miniaturized spectrometers

Photonic crystals allow the fabrication of miniaturized spectrometers
(Nanowerk Spotlight) Spectrometers are used in materials analysis by measuring the absorption of light by a surface or chemical substance. These instruments measure properties of light over a specific portion of the electromagnetic spectrum. In conventional spectrometers, a diffraction grating splits the light source into several beams with different propagation directions according to the wavelength of the light. Thus, to achieve sufficient spatial separation for intensity measurements at a small slit, a long light path – i.e., a large instrument – is required.
However, for lab-on-a-chip or microTAS (total analysis system) applications, the spectrometer must be integrated into a sub-centimeter scale device to produce a stand-alone platform. To achieve this, researchers at the Korea Advanced Institute of Science and Technology (KAIST) propose a new paradigm in which the spectrometer is based on an array of photonic crystals with different bandgaps.
"Because photonic crystals refelct light of different wavelengths selectively depending on their bandgaps, we can generate reflected light spanning the entire wavelength range for analysis at different spatial positions using patterned photonic crystals," Seung-Man Yang, Director of the National Creative Research Initiative Center for Intergrated Optofluidic Systems and Professor of the Department of Chemical & Biomolecular Engineering at KAIST, tells Nanowerk. "Therefore, when the light source impinges on the patterned photonic crytals, we can construct the spectrum using the reflection intensity profile from the constituent photonic crystals."
Photonic crystals – also known as photonic band gap material – are similar to semiconductors, only that the electrons are replaced by photons (i.e. light). By creating periodic structures out of materials with contrast in their dielectric constants, it becomes possible to guide the flow of light through the photonic crystals in a way similar to how electrons are directed through doped regions of semiconductors. The photonic band gap (that forbids propagation of a certain frequency range of light) gives rise to distinct optical phenomena and enables one to control light with amazing facility and produce effects that are impossible with conventional optics.
To demonstrate this new concept based on patterned photonic crystals, Yang and his group used non-close-packed colloidal crystals of silica particles dispersed in photocurable resin. Due to the repulsive interparticle potential, monodisperse silica particles spontaneously crystallize into non-close-packed face-centered cubic (fcc) structures at volume fractions above 0.1. Therefore, the particle volume fraction determines both the lattice constant and the bandgap position.

The scale bars in a, c and d are 1 cm, 2mm and 2 µm, respectively. (reprinted with permission from Wiley-VCH Verlag)
Reporting their findings in a recent issue of Advanced Materials ("Integration of Colloidal Photonic Crystals toward Miniaturized Spectrometers"), the KAIST team has demonstrated the integration of colloidal photonic crystals with 20 different bandgaps into freestanding films (prepared by soft lithography), and their application as a spectrometer.
Yang explains that the team was able to precisely control the photonic bandgap by varying the particle size and volume fration.
"The prepared colloidal composite structures showed high physical rigidity and chemical resistivity" he says. "The composite structure is suitable for spectroscopic use due to the small full widths at half maximum (FWHMs) of the reflectance spectra, which mean that there is little overlap of the reflectance spectra of neighboring photonic crystal strips."
"On the other hand" says Yang, "porous photonic crystals showed large FWHMs and high reflectivities, which should prove useful in many practical photonic applications that require high optical performance and physical rigidity as well as simple and inexpensive preparation."
In addition to fabricating miniaturized spectrometers, which can for instance be integrated into small lab-on-a-chip devices, these integrated photonic crystals can be potentially used for tunable band reflection mirrors, optical switches, and tunable lasing cavities. Moreover, patterned photonic crystals with RGB colors are well-suited for use in reflection-mode microdisplay devices.
Yang points out that, although the spectrometric resolution can be reduced by employing the smaller bandgap interval and photonic bandwidth, there is a limitation. "Now, we are studying photonic crystals with continuous modulation of bandgap position. We expect that the photonic crystals can reduce the resolution to 0.01 nm."

President Suh Hosted Press Conference with Seoul-based Correspondents, on March 9, 2010
President Suh Hosted Press Conference with Seoul-based Correspondents, on March 9, 2010
President Nam-Pyo Shu had a press conference with foreign correspondents based in Seoul, South Korea, on March 9, 2010 at Seoul Foreign Correspondents’ Club (SFCC).
Prior to the conference, the president and correspondents attended a ceremony for the completion of Online Electric Vehicles (OLEV) that carries passengers to look around the amusement park, Seoul Grand Park, in Gewacheon City. OLEV was developed and built by KAIST. Following President Suh’s opening speech, a questions and answers (Q&A) session between the president and reporters proceeded.
In his opening speech, President Suh said electric vehicles are an alternative to conventional automobiles with combustion engines, and in order to manufacture affordably priced electric vehicles on a large scale, their charging should be streamlined. In response, KAIST has come up with the online electric vehicle concept.
He added, without installing separate charging stations, OLEV receives electric power from the cables buried underground while driving, idling, or parking. Its connection to a power source is non-contact.
President Suh expressed his excitement for demonstrating OLEV at Seoul Grand Park that its system works as KAIST has designed and predicted. He showed his confidence that KAIST is indeed at the stage to implement OLEV in Seoul City soon and hoped to demonstrate it at the upcoming G-20 Summit to be held in November 2010 in Seoul City.
During the Q&A session, reporters cited the construction of OLEV at the amusement park and mainly asked about a possibility of its commercialization. Other topics, they also questioned about, were hurdles related to the development and commercialization of OLEV; level of cooperation received from industries and central/local governments; technological breakthroughs and accomplishments; future development plans for the commercialization; and reactions from the public and government.
Media outlets participated in the conference were Reuters, AFP, the International Herald Tribune, ABC News, Bloomberg News, Businessweek, Voice of America, Sankei Shimbun, and etc.
