Professor Seong-Ihl Woo Develops New High-Speed Research Method
Professor Seong-Ihl Woo Develops New High-Speed Research Method Reduce research periods and expenses for thin film materials several ten times Posted on the online version of Proceedings of National Academy of Sciences of the United States of America (PNAS) on January 9 A team led by Seong-Ihl Woo, a professor of KAIST Department of Chemical & Biomolecular Engineering and the director of the Center for Ultramicrochemical Process Systems, has developed a high-speed research method that can maximize research performances and posted the relevant contents on the online version of Proceedings of National Academy of Sciences of the United States of America (PNAS), a distinguished scientific journal, on January 9, 2007. Professor Woo’s team has developed a high-speed research method that can fabricate several tens or several thousands of thin films with different compositions (mixing ratio) at the same time and carry out structural analysis and performance evaluation more than ten times faster and accurately, which leads to the shortening of the research processes of thin film materials. This is an epoch-making method that can reduce research periods and expenses several ten times or more, compared to the previous methods. The qualities of final products of electronic materials, displays, and semi-conductors depend on the features of thin film materials. Averagely, it takes about two weeks or longer to fabricate a functional thin film and analyze and evaluate its performances. In order to fabricate thin film materials in need successfully, more than several thousand times of tests are required. The existing thin film-fabricating equipment is expensive one demanding high-degree vacuum, such as chemical vapor deposition, sputtering, physical vapor deposition, laser evaporation, and so on. In order to fabricate thin films of various compositions with this equipment, a several million won-worth target (solid-state raw material) and precursors (volatile organic metal compound) pricing several hundreds won per gram are required. Therefore, huge amount of experiment expense is demanded for fabrication of several ten thousands of thin films with various compositions. Professor Woo’s team has developed ‘combinatorial droplet chemical deposition’ equipment, which does not demand high-degree vacuum and is automated by computers and robots, by using a new high-speed research measure. The equipment is priced at about 1/5 of the existing equipment and easy for maintenance. This equipment uses cheap reagents, instead of expensive raw materials. Reagents necessary to form required compositions are dissolved in water or proper solvents, and then applied by high frequencies to make several micrometer-scaled droplets (fine liquid droplet). Theses droplets are moved by nitrogen and dropped onto a substrate, which is to be fabricated into a thin film, and then subsequent thermal treatment is applied to the substrate to fabricate a thin film of required composition. At this moment, several tens or several hundreds of thin films with various compositions can be fabricated at the same time by reducing the size of thin film specimens into millimeter scale with the use of shade mask and adjusting vaporization time with masks, the moving speed of which can be adjusted. The expenses for materials necessary for the fabrication of thin films with this equipment amount to several ten thousands won per 100 grams, which is in the range of 1/100 and 1/10 of the previous methods, and the research period can be shortened into one of several tenth. “If this new method is applied to the development of elements in the fields of core energy, material and health, which have not been discovered by the existing research methods so far, as well as researches in thin film material field, substantial effects will be brought,” said Professor Woo. ‘Combinatorial droplet chemical vaporization’ equipment is pending a domestic patent application and international patent applications at Japan and Germany. This equipment will be produced by order and provided to general researchers.
Singer Janghoon Kim Donates Development Fund to KAIST
Singer Janghoon Kim Donates Development Fund to KAIST - Generously donates part of earnings from his concert where HUBO performed for development of science - Opportunity for activation of science culture through encounter between science and culture Singer Janghoon Kim donated 50 million won from his concert earnings for KAIST development fund. Singer Kim visited KAIST on January 16 (Tue) and donated the development fund at the joint lecture room in KAIST Mechanical Engineering B/D. Singer Kim had a concert at the end of the last year where he performed with ‘HUBO’ and ‘Albert HUBO’, human-like robots of KAIST HUBO center. Singer Kim made a donation to express his gratitude to KAIST Professor Joonho Oh and his research team, who assisted his concert actively to allow HUBO to join the concert in spite of technical difficulties and research obstacles. “Although HUBO has performed various activities so far, it is the first time to make a successful performance with a singer on a stage. Honestly, I hesitated a lot to allow HUBO to join Kim’s concert due to safety problems etc., but I was so impressed by Kim’s interest and passion for science, and thus decided HUBO’s joining the concert. This is the first case how robots can exchange with public cultures. I wish this case will be a momentum to activate science culture and make people feel closer to science,” Professor Oh said. The donation will be spent partly as KAIST development fund (20 million won) and partly on the publicity of science and technology via HUBO (30 million won).

Nerve-protecting gene discovered
Korean scientists for the first time have identified a gene that blocks nerve damage from fevers and the use of narcotics, a state-run research institute said yesterday. The finding may open the way for new medicine that can prevent the loss of brain function which is frequently caused by excessive stimulation of nerves and abnormally high body temperature. "The research is in an early stage. But this approach has the potential to develop genetics-based preventatives against brain-attacking diseases," said Kim Jae-seob, a bioscience professor of the Korea Advanced Institute of Science and Technology, who led the study. The researchers named the gene Pyrexia, which means fever. Kim"s team extracted it from genetically engineered fruit flies using a genome-screening system. In laboratory tests, they found that the gene is activated to 39 degrees Celsius or higher. The researchers enhanced Pyrexia"s functionality in some fruit flies while removing the gene from others to observe their different reactions when exposed to high temperature. "The fruit flies without the gene showed severe nerve disorder and suffered paralysis of brain function, while Pyrexia-enhanced flies maintained their normal brain conditions," the professor said. The researchers got the same result from experiments with human cells, he said. There are a lot of channel proteins, which enable ions to enter and exit the cell, that react to the level of temperature, but Pyrexia is the first of its kind that actually protects the neurons from external stimulus, he said. The finding will appear on the March edition of the London-based science magazine Nature Genetics. THE KOREA HERALD 2005.1.31 (email@example.com) By Kim Tong-hyung

The Expo seeks to contribute to economic development through promoting exchanges between exceptional Korean and Chinese start-up companies, and to promote cooperation between high-tech industries and academic institutions through academic and technological exchanges between each nation"s best technology institutions. The Expo is a big international affair held by a university from Korea and one from China. The Expo is also a means to implement the agreement between KAIST and Tsinghua in 2002 to promote exchanges between the two universities and to conduct international co-research. It is sponsored by various technology institutions of both nations. The Expo is different from other expos in that it is a specialized expo where Tsinghua-related companies, experts, and buyers participate to discuss the transfer of technologies and to deal in trades. Also, to insure that the Expo is beneficial to participating Korean companies, the Expo plans to offer business talks with at least ten Chinese companies per company. From Korea, thirteen companies from enterprise-incubation center and graduate start-ups with high-tech start-ups in areas of IT, BT, NT and mechatronics that are possible in exporting related products or transferring related technologies are participating. From China, Tsinghua-related companies, China Telecom, China Unicom, and other companies under China Telecommunication Association with other famous Chinese companies are expected to participate. In addition to exhibitions, co-work between KAIST and Tsinghua"s research centers and KAIST"s Technology Transfer & Exchange Center"s explanation on public technology transfer are taking place during the Expo. And, after three days of the Expo, about ten companies will move to Chungking, a city in western China to hold a product and technology explanation session.
Personal data found on many used hard drives
JoongAng Daily / 2004.03.09 (photo : Professor Song-chun MoonKAIST Graduate School of Management) Many secondhand computer hard drives that are being sold through the Internet formerly belonged to businesses and are therefore full of business records containing personal information, the Korea Advanced Institute of Science and Technology (KAIST), a leading local science and technology school, said yesterday. To determine whether personal information had been properly deleted, the business database research team at KAIST"s business school conducted an experiment in which it randomly bought 41 hard drives through Internet auction sites beginning in April 2003 and analyzed their contents. It said 26 hard drives out of the total, or 65 percent, had not even been reformatted to remove data. On those drives were business records containing the names, birth dates, home and company addresses, telephone numbers and health examination records of 1,349 people. Also, the team found 568 resident identification numbers on the drives. "Secondhand hard disks are an open storehouse of personal information [from business records]," said the team"s head, Moon Young-chul. "We found such personal data for an average of 60 people per used disk." Mr. Moon said that reformatting hard drives alone will not delete all information recorded on them. He said special software designed to completely delete data should be used or such disks should be destroyed. by Ko Ran / 2004.03.09
