Professor Kwang-Hyun Cho publishes Encyclopaedia of Systems Biology
Professor Kwang-Hyun Cho
KAIST Biological and Brain Engineering Department’s Professor Kwang-Hyun Cho edited the Encyclopaedia of Systems Biology with three scholars, all experts of Systems Biology in England, Germany and the United States. It is rare that a Korean scientist edits a world renowned academic science encyclopaedia.
The Encyclopaedia, published by the New York office of Springer Verlag, was a grand international project five years in the making by 28 editors and 391 scientists with expertise in Systems Biology from around the world. The Encyclopaedia compiles various research areas of Systems Biology, the new academic paradigm of the 21st century through the integration of IT and BT, comprehensively on 3,000 pages in 4 four volumes.
Professor Kwang-Hyun Cho, who led this international project, majored in electrical engineering and pioneered the field of Systems Biology, the integrated study of biological sciences and engineering, as a new integrated field of IT since the 1990s. The professor has achieved various innovative research results since then. Recently he has investigated “kernel,” an evolutionary core structure in complex biological networks and developed a new cancer treatment through the state space analysis of the molecular network of cancer cells. His work was published in Science Signalling, a sister journal of Science, as a cover story several times, and contributed to foundational research as well as commercialisation of the integrated fields of IT and BT.

Using Light to Deliver Drugs to the Brain
The cerebral blood vessels have a unique blood-brain barrier. Using this unique structure, Professor Choi Chul Hee (Department of Bio-Brain Engineering) developed a technique to deliver drugs safely to the brain using lasers to alter the diffusivity of the blood-brain barrier.
The blood-brain barrier allows the entry of only those drugs related to metabolic functions which made the entry of other drugs difficult.
Due to this property it was difficult to administer the drug to a patient and have it affect the patient. Therefore the question was is it possible to maintain the effectiveness of the drug and allow it to pass through the barrier?
The conventional method was to actually alter the structure of the drug or drill of small hole in the head and administering the drug directly, but these methods proved to be high risk and expensive.
Professor Choi’s team used an ultra-short frequency laser beam on the barrier for 1/1000th of a second on the barrier to temporarily inhibit its function thereby allowing the drug to enter the brain safely.

Workshop on Biomedical IC to Be Held on March 26
KAIST will hold a workshop on "biomedical IC for future healthcare system" on March 26 at a lecture room of the School of Electrical Engineering & Computer Science. The workshop is organized by SEECS and the Korean Institute of Next Generation Computing.
At the workshop, a variety of new technologies expected to expedite the development of biomedical systems will be presented. KAIST Prof. Hoi-Jun Yoo will speak on the "body channel communication" using the human body as the signal transmission medium and Dr. Seung-Hwan Kim of Electronics and Telecommunications Research Institute (ETRI) on a wearable vital sign monitoring system.
Other subjects are CMOS (complementary metal-oxide semiconductor) fully electronic biosensor for biomolecular detection to be presented by KAIST Prof. Gyu-Hyeong Cho; nerve interface and IC (integrated circuit) system design by KAIST Prof. Yoon-gi Nam; design of neural recording and stimulation IC using time-varying magnetic field by KAIST Prof. Seong-Hwan Cho; low power multi-core digital signal processor for hearing aid by Dong-Wook Kim, senior researcher at the Samsung Advanced Institute of Technology; and a non-contact cardiac sensor by KAIST Prof. Seung-Chul Hong.
With the advent of the ageing society, medical expenses of the elderly people are rapidly increasing. As a way to address the issue, interests are growing in "ubiquitous healthcare," a technology that uses a large number of environmental and patient sensors and actuators to monitor and improve patients’ physical and mental condition.
The upcoming workshop is the first academic event on biomedical integrated chips to be held in Korea. The workshop will provide a valuable opportunity for experts in biomedical area to get together and examine the present status of Korean biomedical area and discuss about its future, KAIST officials said.

KAIST Wins First Prize at Recon Challenge of Int"l Magnetic Resonance Society
Professor Jong-chul Ye of the Department of Bio and Brain Engineering and Hong Jeong, a doctorate student, won the first prize at the Recon Challenge held as part of a workshop sponsored by the International Society for Magnetic Resonance in Medicine (ISMRM) held in Sedona, the United States.
The workshop took place under the theme of “data sampling and image reconstruction” on Jan. 25-28 in Sedona, Arizona, the United States. The KAIST team beat out major magnetic resonance imaging groups from the U.S. and Europe.
The Recon Challenge is a biennial competition highlighting different reconstruction strategies and metrics to compare them. ISMRM is an international, nonprofit, scientific association which promotes communication, research, development, and applications in the field of magnetic resonance in medicine and biology and other related topics.
At the competition, the KAIST team presented a new dynamic MRI algorithm called k-t FOCUSS that is optimal from a compressed sensing perspective. The main contribution of the method is extension of k-t FOCUSS to a more general framework with prediction and residual encoding. The prediction provides an initial estimate while the residual encoding takes care of the remaining residual signals.

Prof. Cho Identifies Dynamics of Signal Transportation System in Control of Cell Proliferation
KAIST, Jan. 22, 2009 -- A research team led by Prof. Kwang-Hyun Cho of the Department of Bio and Brain Engineering, KAIST, has identified a hidden mechanism of the dynamic behavior of signal transportation system involved in the control of cell proliferation, university authorities said.
The finding is expected to provide a clue to appropriately controlling the pathway of ERK protein which is known to play a significant role in causing and spreading cancer. The research was featured as the cover paper of the latest online edition of the Journal of Cell Science.
The Ras-Raf-MEK-ERK pathway (or ERK pathway) is an important signal transduction system involved in the control of cell proliferation, survival and differentiation. However, the dynamic regulation of the pathway by positive- and negative-feedback mechanism, in particular the functional role of Raf kinase inhibitor protein (RKIP) are still incompletely understood. RKIP is a physiological endogenous inhibitor of MEK phosphorylation by Raf kinases, but also participates in a positive-feedback loop in which ERK can inactivate RKIP.
"We attempted to unearth the hidden dynamics of these feedback mechanisms and to identify the functional role of RKIP through combined efforts of biochemical experiments and computer simulations based on an experimentally validated mechanical model," Prof. Cho was quoted as saying.
