Research Outputs over Carbon Nanotube by Prof. Choi Selected as Research Highlight by ACS
A research team headed by Seong-Min Choi, a professor of Nuclear and Quantum Engineering, KAIST, has developed technologies to stably disperse carbon nanotube particles in aqueous solutions and organic solvents, essential for industrial applications of carbon nanotube, and discovered the dispersion characteristics of carbon nanotube. The research outputs have been published by ‘Advanced materials’ (19, 929, 2007), the most distinguished journal in Material Science field, and introduced as Research Highlight at the May 7th edition of ‘Heart Cut’ by the American Chemical Society (ACS).
A number of processes for industrial applications of carbon nanotube require the dispersion of carbon nanotube in aqueous solutions or organic solvents, and thus far, surfactant particles or DNAs have been used to disperse carbon nanotube particles. However, they have shortcomings of easy destruction of dispersion. In order to overcome such shortcomings, Prof. Choi’s team produced carbon nanotube particle-dispersed aqueous solutions by using surfactant particles and then polymerized surfactant particles absorbed to the surfaces of carbon nanotube in situ to develop carbon nanotube with hydrophile and safe surfaces. The functional carbon nanotube so obtained shows features of easy dispersion in aqueous solutions and organic solvents even after being processed, such as freeze drying, therefore, is expected to significantly contribute to the development of application technologies of carbon nanotubes. Tae-Hwan Kim and Chang-Woo Doh, both doctoral students, played key roles in the researches carried out under the auspices of the Ministry of Science and Technology (MOST) as a nuclear power R&D project, and the relevant technologies were filed for patent applications.

Maximum Yield Amino Acid-Producing Microorganism Developed with use of System Biotechnology
Maximum Yield Amino Acid-Producing Microorganism Developed with use of System Biotechnology
A team led by Sang-Yup Lee, a distinguished professor of Chemical and Biomolecular Engineering and chair professor of LG Chemical, has succeeded in developing maximum yield L-valine-producing microorganism by using System Biotechnology methods. The research results will be published at the April fourth week (April 23 - 27) edition of the Proceedings of the National Academy of Sciences (PNAS) of the USA.
Prof. Lee’s team has developed maximum yield amino acid-producing microorganism (target substance of L-valine, an essential amino-acid) by using microorganism E cell system and simulation methods.
His team produced initial producing microorganism by selectively operating necessary parts in colon bacillus genome and excavated preliminary target gene which is to newly be operated through transcriptome analysis using DNA chips. Then they performed a great amount of gene deletion experiment on computer by using MBEL979, E-cells of colon bacillus, and excavated secondary engineering targets. And they finally succeeded in developing maximum yield valine-producing microorganism that can extract 37.8 grams of valine from 100 grams of glucose by applying experiment results to the actual development of microorganism so as to achieve the optimization of metabolic flux in cells,
Prof. Lee said, “Since successfully used for the development of microorganism on a systematic system level, system biotechnology methods are expected to significantly contribute to the development of all biotechnology-relevant industries. At the beginning, we had huge obstacles in fusing IT and BT, but my team mates cleverly overcame such obstacles, hence I’m very proud of them.” The producing microorganism and its developing methods are pending international applications (PCT).

KAIST To Hold Robot Competition
KAIST To Hold Robot Competition
KAIST (President Nam-Pyo Suh) will be holding ‘the 6th Intelligent SoC Robotwar 2007’ and is now receiving online applications at the official web site of the competition, www.socrobotwar.org. Application deadline is May 31, Thursday.
‘Intelligent SoC Robotwar’ is a competition of intelligent robots employing System on Chip (SoC) that commenced in 2002.
In the competition, participants will embody their ideas in the same intelligent robot platforms and robot bodies, and how well the ideas are embodied will decide winners.
In the part of tank robot competition (left photo), tank-like robots attack enemy robots by using laser, which demands technologies of scene analysis, radio communication and speech recognition. Hence, a variety of recognition algorithms and motion algorithms significantly affect match results.
Taekwon robot competition is a fight competition of two-leg robots. In the competition, robots equipped with scene analysis technologies perceive the location, distance and motion of enemy robots and do motions of attack and defense with no control by operators.
Teams must be made up of two or more persons including undergraduate or graduate students and all teams are entitled to participate in theoretical and practical education on platform boards for robots and intelligent robots. Final winner will be decided through qualifying test, preliminary matches and main matches.
“The most distinct characteristic of this competition is robot’s intelligence takes top priority. It’s not remote control-operated robots but autonomously operating intelligent robots that will make Korean robot-related industries further profitable. Considering that last year, total 138 teams participated in the competition and an award from the Prime Minister was given to the winner, the competition undoubtedly hold the top position among robot-related competitions,” said Hee-Joon You, President of the competition committee and a professor of Electrical Engineering.
Details on the competition are as follows:1. Purpose● To foster highly specialized technicians in the field of SoC through the embodiment of intellectual robots adopting SoC● To pave foundations for the enhancement of national competitiveness through the vitalization of IT-SoC and intellectual robot fields, next-generation growth momenta

3rd Ubiquitous Fashionable Computer Contest
KAIST will be receiving until May 31, Thursday, applications for ‘the 3rd Ubiquitous Fashionable Computer (UFC)’ Contest, which will take place under the title of ‘Enjoy U-life with UFC’.
The contest has begun in 2005 by KAIST and the Korean Society for Next-Generation Computing to raise people’s concern over next-generation computing and to prepare for the upcoming ubiquitous era.
‘UFC’ refers to a wearable computer small and light enough to be worn on human bodies or clothes so that users can use computers with no restriction while moving. This terminology was created by Korea.
The contest includes designated items division and free items division, and not only university students but also general public can participate in the free items division. Teams qualified for the final contest in the designated items division will be offered wearable computer platform and 1.5 million won of production cost. The final contest will take place at the UFC fashion show stage ‘Next-Generation Computing Exhibition’ at KOEX in November.
Hee-Joon You, Co-president of the Contest Committee and a professor of Electrical Engineering, stressed on the future life made joyful by IT technologies by saying, “Considering the title of the contest, we’ve selected ‘games enjoyed with UFCs’ as a mission of the designated items division to combine games, rising software, and wearing computers, hardware.”
UFC is a brand-new field that fuses IT technologies and fashion, seeking the improvement of computer technologies and fashion creation. UFC, a further advanced wearable computer than existing ones, is an important advanced field that leads computer industries in the ubiquitous era.
