Korean Researchers Develop Skin-Like Tactile Sensor
THE KOREA TIMES2005.1.31(Mon) A South Korean scientific research center said Sunday that it has developed a tactile sensor capable of functioning like human skin. The left picture shows the letters of the Korea Advanced Institute of Science and Technology (KAIST) caught through a tactile sensor functioning like human skin and the right picture is its enlarged image. Scientists from KAIST developed the precision tactile sensor with 1-millimeter spatial resolution. The tactile sensor is made of polydimethylsiloxane, a synthetic rubber, and has a 1-millimeter spatial resolution capability, the Korea Advanced Institute of Science & Technology (KAIST) said. ``Many tactile sensors have been developed so far, but ours has the highest spatial resolution capability, flexibility, softness and extensibility,’’ said Lee Hyung-kyu, who led the development project. Late last year, the University of Tokyo unveiled a tactile sensor with a spatial resolution capability of 2 millimeters. Lee said his team will announce the results of their research at an international conference on micro-electro-mechanical systems, to be held early next month in the U.S. city of Miami. The new sensor is widely expected to lay the foundation for coating humanoids such as South Korea"s HUBO or Japan"s ASIMO with artificial skin. HUBO is a humanoid robot recently developed by KAIST. It is capable of moving its fingers independently, dancing and shaking hands with people by using its 41 joints. Japan"s ASIMO, an acronym for Advanced Step in Innovative Mobility, was unveiled in 2000 as the world"s most advanced bi-pedal robot. Through several upgrades, it is now able to spin in the air, bend or twist its torso and maneuver around obstacles in its path.

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 (thkim@heraldm.com) By Kim Tong-hyung

Gene Protecting Brain Nerves Discovered
THE KOREA TIMES 2005.1.31By Kim Tae-gyu / Staff Reporter South Korean scientists have for the first time discovered genes tasked with protecting brain nerves. Korea Advanced Institute of Science and Technology professor Kim Jae-seob said Sunday the new genes, named pyrexia, shield brain nerves from outside stimuli, including high temperatures. ``The channel gene of pyrexia will open the door to developing new-concept medicines for brain damage in patients of high fever or drug addicts,’’ he said. The channel gene refers to transport proteins, which provide a static passageway for a variety of essential substances to enter into cells. ``Up until now, a lot of channel genes activated by temperatures have been identified. But among them, pyrexia is first that guards brain nerves from external stresses,’’ Kim said. Kim’s team learned pyrexia plays a pivotal role in the body through experiments with genetically engineered flies that did not have any pyrexia. Up to 60 percent of the pyrexia-depleted mutants were paralyzed within three minutes of exposure to a temperature of 40 degrees Celsius. In comparison, just 9 percent of normal flies were paralyzed with the same stimulus, indicating pyrexia is responsible for protecting animals from high-temperature stress. ``Our next goal is to develop pyrexia-embedded drugs, which can be expected to commercially debut in about five years,’’ Kim said. Kim has already applied for international patents for his medical breakthrough, which will be printed in the March edition of Nature Genetics, a science journal. voc200@koreatimes.co.kr

KAIST Develops Thinking, Feeling Human-Like Robot
By Kim Tae-gyu / Staff ReporterTHE KOREA TIMES 2005.1.31(page 1) South Korean scientists created the world"s first artificial species, a software robot with ``genes"" and ``chromosomes."" Kim Jong-hwan, professor at Korea Advanced Institute of Science and Technology, said Sunday his team had developed a robot with 14 chromosomes, which gives the machine a ``personality."" ``This robot is a software-based one, sometimes called a sobot. It has a unique synthetic character determined by its specific combination of 14 chromosomes,"" the 47-year-old Kim said. When Kim"s team gave a stimulus to the chromosome-equipped sobots, they showed totally different responses even under the same environment due to their distinctive personalities. Several cognitive sensors enable the prototype models to identify 47 differing outside stimuli. The virtual robots also have 77 behavior patterns. ``Because a sobot is basically a software system, it can easily travel to other robots and multiply. In the middle of such processes, it can evolve through crossover and mutation,"" Kim said. With the development of associated technologies, Kim expected the number of chromosomes would be augmented as sobots evolve to a more sophisticated species in the future. The capacity to load large volumes of data is related to the evolution of sobots. Currently, 14 chromosomes consist of roughly 2,000 bytes of data. The effort to incorporate the sobot into a platform, robot hardware, is now underway and Kim"s team looks to unveil the new-concept species as soon as next month. ``Diverse behavior patterns driven by sobots" specific personalities will be precisely translated into action just like the soul rules the body,"" Kim said. Kim did not think the robotic evolution would lead to the human race being threatened; the concept of the recent blockbuster ``I, Robot."" ``If we design the chromosomes safely, the self-reproducing robot will not post a threat back to us,"" Kim said. Kim first revealed the robotic breakthrough at a keynote speech of the International Conference on Autonomous Robots and Agents, held in New Zealand last December. Kim is also known as pioneer in the field of robot football and has headed the Federation of International Robot-soccer Association (FIRA) since its foundation in 1999. voc200@koreatimes.co.kr

18th Student Council Elected
The KAIST Herald December 3, 2003 The votes were cast and counted on November 27. Donggodongrak won the election of the 18th Undergraduage Student Council of Korea Advanced Institute of Science and Technology (KAIST). Of the 2,340 eligible voters for the 18th student council election, 1,304 votes, or about 56 percent of the total, were amassed after a full day of election on November 27. The two candidate teams, waiting to hear the result with much anxiety, were juniors Hye-min Kim and Jung-mo Kim running for the president and vice president positions, respectively, of the team "Donggodongrak" and juniors Dong-geun Kim and Yong-jae Yoon running for the same positions, respectively under the name "Woorung Chonggak." Donggodongrak secured over 58 percent of the votes, with 760 supporting ballots, while Woorung Chongak polled 503 votes, or about 39 percent of the votes. Forty-one votes, or three percent of the votes cast were spoiled votes. With more than half the voters having participated, the election was valid, and Donggodongrak was declared the new student council of KAIST. The election platform of the Donggodongrak team largely consist of four themes, composed of several smaller goals. First, they assert the "togetherness" of the student government and plan to achieve it by publishing monthly newsletters, hosting an open outdoor student council every other week, and creating various committees. Secondly, they assert under the theme of an "improving" student government that they will promote festivals and events among the sixteen departments, form an official "class" of the freshmen, and broaden the association of the student representatives. Third, Donggodongrak declares it wants to create an "open and just environment" by holding periodic meetings with the school for direct discussions of school policies; and by taking care of the welfare of the students in detail. Finally, they advocate "a student government that communicates with society"; they will support opportunities to become more aware of various issues of society. President Hye-min Kim, a graduate of Pusan Science High School, has participated in various intramural, socially active groups, and is majoring in applied mathematics. Vice-president Jung-mo Kim is a graduate of Mokpo High School and studies mechanical engineering.

Researchers Find Mechanism of Tumor Suppressor Genes
By Kim Tae-gyu. Staff ReporterTHE Korea Times 02-06-2004 Korean scientists continue to break new ground in fighting cancer as domestic researchers examined the mechanism of a gene which can help detect and treat various sorts of cancer. Korea Advanced Institute of Science and Technology (KAIST) Prof. Lim Dae-sik on Thursday said his team uncovered the mechanism of RASSF1A (Ras Association Domain Family 1 A), or tumor suppressor genes, for the first time in the world. The gene was widely considered to play an important role in reducing the proliferation of cancer cells, but its exact function and processes have remained unknown up to now. It is the second cancer-related breakthrough by Koreans in a week after Korea Institute of Science and Technology (KIST) Prof. Chung Hesson unveiled the oral anti-cancer drug. ``Cancer results from the failed management of cell cycles due to things like radiation. After a two-year intensive study, we found out how RASSF1A governs the cell cycle,"" Lim said. Lim added cancer is caused by abnormal cells, which continue to grow and divide out of control unlike normal cells, which die over time. Cancer cells develop into malignant tumors, eventually inflicting damaging effect on the human body. As a result, a lack of the RASSF1A indicates a high possibility of cancer and injection of it into cells is believed to help cure the deadly disease, according to Lim. Dr. Song Min-sup, who took charge of the research, said the findings will especially pave the way for the detection and treatment of lung cancer. ``The dearth of RASSF1A was reported mostly in the case of lung cancer. The new findings will provide insight into the diagnosis and cure of lung cancer from its early stages,"" Song explained. Lung cancer is a very elusive disease because it doesn"t cause symptoms in its infancy. When symptoms do occur, usually it is too late. ``We expect commercial detection kits or drugs for lung cancer in around five years after pre-clinic experimentation and two-phase clinic trials,"" Song expected. Details of the study is available in the scientific journal Nature Cell Biology in its February edition. voc200@koreatimes.co.kr
