A Light Weight, Energy Effcient Household Polysomnography (PSG) System Developed
A smart ‘household polysomnography (PSG) system’ was developed by domestic research team.
Professor Yoo Hui Joon and his research team of KAIST’s department of Electricity and Electronic Engineering successfully developed a PSG system that is light weight and has high performance levels. The conventional PSG systems were complex with numerous lines and wires.
The PSG is used to monitor biological signals during sleep and the monitored results are used to diagnose and cure sleep-related illnesses and disorders. However because of restrictions like the size of the machine, impurities, and the change in environment, multiple trials over several days were required to obtain accurate data.
The system developed by the research team is lighter than a q-tip so as to not disturb the patient’s sleep. It also has Intelligent Circuit (IC) that detects when sensors come detached and automatically replaces the sensor with another sensor thereby allowing continual monitoring of the user.
A low-power consuming circuit was implemented allowing the entire system to run continuously on a single coin battery for 10 hours which effectively decreased the weight of the system and simultaneously allows for uninterrupted monitoring of the user over the entire sleep cycle.
Even a remote diagnosis system can be implemented. The user will don the PSG and sleep at home, ensuring that a normal heat beat rate, brain waves, breathing, etc. will be monitored. The data procured overnight can be sent to the experts online who will be able to diagnose remotely.
The research team plans on performing research in cooperation with the KAIST hospital and U-Healthcare research.
The research result is winning worldwide rave. The system was announced in the International Solid-State Circuits Conference (ISSCC) and was published in ISSCC magazine and in Japan’s NIKKEI Electronics January edition.

KAIST paves the way to commercialize flexible display screens
28 Feb 2011
Transparent plastic and glass cloths, which have a limited thermal expansion needed for the production of flexible display screens and solar power cells, were developed by researchers at KAIST (Korea Advance Institute of Science & Technology).
The research, led by KAIST"s Professor Byoung-Soo Bae, was funded by the Engineering Research Center under the initiative of the Ministry of Education, Science and Technology and the National Research Foundation. The research result was printed as the cover paper of "Advanced Materials".
Professor Bae"s team developed a hybrid material with the same properties as fiber glass. With the material, they created a transparent, plastic film sheet resistant to heat. Transparent plastic film sheets were used by researchers all over the world to develop devices such as flexible displays or solar power cells that can be fit into various living spaces. However, plastic films are heat sensitive and tend to expand as temperature increases, thereby making it difficult to produce displays or solar power cells.
The new transparent, plastic film screen shows that heat expansion index (13ppm/oC) similar to that of glass fiber (9ppm/oC) due to the presence of glass fibers; its heat resistance allows to be used for displays and solar power cells over 250oC.
Professor Bae"s team succeeded in producing a flexible thin plastic film available for use in LCD or AMOLED screens and thin solar power cells.
Professor Bae commented, "Not only the newly developed plastic film has superior qualities, compared to the old models, but also it is cheap to produce, potentially bringing forward the day when flexible displays and solar panels become commonplace. With the cooperation of various industries, research institutes and universities, we will strive to improve the existing design and develop it further."

New Bio-Clock gene and its function found
The Ministry of Education, Science and Technology announced that a Korean research team has found a new gene responsible for maintaining the bio-clock (twenty-four) and its mechanism.
Twnety-four was led by Professor Choi Joon Ho and Dr. Lee Jong Bin of KAIST (department of Biology) and was a joint operation with Professor Ravi Allada and Dr.Lim Jeong Hoon of Northwestern University (department of neurobiology) and the result was published in ‘Nature’ magazine.
The research team experimented with transformed small fruit flies for 4 years and found that there was an undiscovered gene that deals with the bio rhythm in the brain which they named ‘twenty-four’.
The understanding with genes prior to twenty-four was that these genes regulate biorhythm in the transcription phase (DNA to mRNA). Twenty-four operates in the step after transcription when the ribosome creates proteins. Especially twenty-four has a great effect on the ‘period protein’ which acts as a sub-atomic clock that regulates the rhythm and life of each cell.
The experiment was innovational in that it was able to scientifically prove the function of the protein produced by the gene.
The result is expected to help solve the problems associated with sleep disorders, jetlags, eating rhythms, bio rhythms, etc.
The name twenty-four was the fact that a day, a cycle, is 24 hours long and the gene’s serial numbers CG4857 adds up to twenty four.

Professor Min Beom Ki develops metamaterial with high index of refraction
Korean research team was able to theoretically prove that a metamaterial with high index of refraction does exist and produced it experimentally.
Professor Min Beom Ki, Dr. Choi Moo Han, and Doctorate candidate Lee Seung Hoon was joined by Dr. Kang Kwang Yong’s team from ETRI, KAIST’s Professor Less Yong Hee’s team, and Seoul National University’s Professor Park Nam Kyu’s team. The research was funded by the Basic Research Support Program initiated by the Ministry of Education, Science, and Technology and Korea Research Federation.
The result of the research was published in ‘Nature’ magazine and is one of the few researches carried out by teams composed entirely of Koreans.
Metamaterials are materials that have physical properties beyond those materials’ properties that are found in nature. It is formed not with atoms, but with synthetic atoms which have smaller structures than wavelengths.
The optical and electromagnetic waves’ properties of metamaterials can be altered significantly which has caught the attention of scientists worldwide.
Professor Min Beom Ki’s team independently designed and created a dielectric metamaterial with high polarization and low diamagnetism with an index of refraction of 38.6, highest synthesized index value.
It is expected that the result of the experiment will help develop high resolution imaging system and ultra small, hyper sensitive optical devices.

Interdisciplinary Research on World Environmental Problems with Humanities
KAIST’s Professor Michael Pak (department of Humanities and Social Sciences) has published a paper in ‘Environmental Science and Technology, ES&T’ and was made Lead Feature.
His was the only paper published with a humanities background and his topic of discussion was ‘Environmentalism Then and Now: From Fears to Opportunities, 1970-2010’ in which he discussed the history of pro-environment activities, the patterns it showed, and its outlook.
Professor Park noted that the problems and concerns over the environment is not a recent phenomenon. It took over 50 years for the environmental problems to resurface after being the ‘hot issue’ of the time during the industrial revolution in the 19th century.
Professor Park deduced that there is a clear historical pattern.
Professor Park insisted that the two areas of Environmental Research ‘Global Warming’ and ‘Change in Weather’. Especially because these two areas are rife with uncertainty as it is, and making policies based on inaccurate information is taking a gamble.
Professor Park majored in history in UC Berkeley, received his masters’ and doctorate at Harvard University and was the professor at Massachusetts College of Art and Design before coming to KAIST at 2008.

Success in differentiating Functional Vascular Progenitor Cells (VPC)
KAIST’s Professor Han Yong Man successfully differentiated vascular progenitor cells from human embryonic stem cells and reversed differentiated stem cells.
The research went beyond the current method of synthesis of embryonic body or mice cell ball culture and used the careful alteration of signal transmission system of the human embryonic stem cells to differentiate the formation of vascular progenitor cells.
The team controlled the MEK/ERK and BMP signal transmission system that serves an important role in the self replication of human embryonic stem cells and successfully differentiated 20% of the cells experimented on to vascular progenitor cells.
The vascular progenitor cells produced with such a method successfully differentiated into cells forming the endodermis of the blood vessel, vascular smooth muscle cells and hematopoietic cells in an environment outside of the human body and also successfully differentiated into blood vessels in nude mice.
In addition, the vascular progenitor cell derived from human embryonic cells successfully formed blood vessels or secreted vascular growth factors and increased the blood flow and the necrosis of blood vessels when injected into an animal with limb ischemic illness.
The research was funded by the Ministry of Education, Science and Technology, 21st Century Frontier Research and Development Institution’s Cell Application Research Department and Professor Ko Kyu Young (KAIST), Professor Choi Chul Hee (KAIST), Professor Jeong Hyung Min (Cha Medical School) and Doctor Jo Lee Sook (Researcher in Korea Bio Engineering Institute) participated in it.
The results of the research was published as the cover paper of the September edition of “Blood (IF:10.55)”, the American Blood Journal and has been patented domestically and has finished registration of foreign PCT.
The results of the experiment opened the possibility of providing a patient specific cure using stem cells in the field of blood vessel illness.
