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.

KAIST-Tsinghua High-Tech EXPO 2004
THE KAIST Herald 2004.5.12
By Jong-kyoung KimThe KAIST Herald Staff Reporter
KAIST and Tsinghua University are holding KAIST-Tsinghua Korea-China High Tech EXPO 2004 from July 12 to 14, at the Beijing International Convention Center. 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

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.

133 Diplomats Worldwide Visit KAIST
THE KAIST Herald April 8, 2004by jong-kyoung Kim
On March 12, diplomatic corps in Korea visited Daedeok Valley"s KAIST after taking a trial run on the Korea Train eXpress(KTX). Composed of ambassadors from 79 nations and 54 international organizations, the 133 diplomatic corps went on board KTX at 10:30 AM in Seoul and arrived in Daejeon at 11:20 AM.
Shortly after arrival, the diplomatic corps attended a luncheon hosted by the Minister of Foreign Affairs and Trade(MOFAT) before paying visits to the Electronics and Telecommunications Research Institute(ETRI) and KAIST. After being introduced to the current issues at KAIST, the diplomatic corps returned back to Seoul at 4:00 PM.
Seventy-nine embassy representatives out of eighty-seven currently stationed in Korea participated in this event, with fifty-four representatives from three international organizations. In addition, officials from the Ministry of Foreign Affairs and Trade, a commercial relations director, and a regional representative accompanied them.
The trial rides on April 1 were organized by the Ministry of Foreign Affairs and Trade to publicize Korea as being the fifth country (after Japan, France, Germany, and Spain) in the world to own an express train and to introduce the growth of Korea"s IT industry through visits to ETRI and KAIST.
Events such as this are held annually to improve the understandings of the diplomatic corps about Korea"s science, technology, culture and art and to further enhance bilateral relations.
