Professor Sejin Kwon develops thruster for small satellite - World’s first application of high-performance liquid propellant to small satellite thruster - Show about four times higher thrust performance than the cold gas thruster of University of Surrey, the state-of-the-art technology in the field of small satellite - Expect a considerable contribution to the extension of the lifespan and mission range of small satellites The team of Professor Sejin Kwon (Department of Aerospace Engineering in KAIST/ President Nam Pyo Suh) and Space Solution Inc. (President Jaehun Lee) have jointly developed a micro thruster for small satellite motion-control. Kwon"s team has succeeded in developing an integrated thruster which can be mounted on a satellite by integrating catalyst reactor and propellant-supplying system, which are the core technologies of small satellite thruster system. For the first time in the world, Kwon’s team employs a high-performance liquid propellant to the thruster. In the thruster, liquid-state hydrogen peroxide is dissolved into vapor and oxygen at the catalytic layer to emit a huge amount of heat. And, the emitted heat is converted into the kinetic energy of the gas to produce a propulsive force. This thruster can perform the motion-control of a several tens-kilogram satellite with a propulsive force of less than one Newton and shows about four times higher thrust performance than the cold gas thruster of University of Surrey, who possesses the state-of-the-art technologies in the field of small satellites. Professor Kwon said, “Although University of Surrey has also tried to develop a similar system, it’s not yet solved the problem on catalytic reactor bed. I expect this thruster will considerably contribute to the extension of the lifespan and mission range of scientific small satellites. Also, this thruster can be employed for the attitude control of the upper end of the launch vehicle, which is now being developed by the Korean Aerospace Research Institute (KARI).” <Thruster module for small satellite application>

Professor Chan Beum Park, requested for joint international research by a German biotechnology enterprise. - Bitop AG (Germany) requested a joint development of medicines for Alzheimer’s disease - The meaning of the financial support by European enterprise to the research result of domestic university. Professor Chan Beum Park (Department of Materials Science and Engineering in KAIST/ President Nam Pyo Suh) has been entrusted with a joint international research for the development of medicines for Alzheimer’s disease from Bitop AG, German biotechnology enterprise. KAIST recently agreed with Bitop AG to cooperate for a research program pursuing the development of inhibitors that inhibit the formation of plaque relevant to amyloid diseases like Alzheimer’s disease. Based on this agreement, KAIST will be provided with a financial support of sixty thousands Euro (about 74 million won) from Bitop AG. Professor Park will perform the screening of inhibitors, which are the core of the research, and KAIST will share patent rights from the research with Bitop AG. It is known that various degenerative nerve diseases like Alzheimer’s disease, Parkinson’s disease, mad cow disease, and so on arise mainly from the accumulation of pathological protein plaque termed amyloid, and environmental stress accelerates the diseases. So far, no effective remedy has been developed for amyloid diseases. Recently, the use of chemicals inhibiting the formation of amyloid has been raised as a potential remedy. Natural small stress molecules extracted from microbes growing in extreme environments like volcanic region on the bottom of the deep sea, etc. are gaining attention as an amyloid inhibitor. Professor Park found out for the first time in the world that Anti-stress materials are effective in inhibiting the formation of amyloid plaque and published that fact in several renowned European scientific journals. After that, Professor Park was requested by Bitop AG for a joint research and has studied for the development of medicines for Alzheimer’s disease using various kinds of Anti-stress materials. Professor Park said, “I’d like to grant a highly valuable meaning to this entrustment since it implies that European enterprises perceive the value of the research result by domestic universities and hope to promote research and development by providing practical financial support, etc. I wish this time’s entrustment will be a momentum to advance Korea’s research level one step higher through active joint researches with enterprises or institutes in U.S. and Europe as well as Bitop AG.” Bitop AG is a German enterprise that produces various Anti-stress materials coming from extreme-loving microbes. Currently, Anti-stress materials are being sold mainly as protein and cell protectants, cosmetic additives, health supplement, etc. Anti-stress materials extracted from microbes well growing in extreme environment of one hundred centigrade or more are expected to perform a role of inhibitors that inhibit the formation of amyloid plaque, the main factor of stress-related degenerative nerve diseases like Alzheimer’s disease, etc. Such Anti-stress materials are gaining attention as a future medicine for Alzheimer’s disease, etc.

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.

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
