Research Conducted on the Development Policy of Medical Researchers in United States
The topic dealt in the paper was “The Vietnam War and Medical Research: Untold Legacy of the U.S. Doctor Draft and the NIH ‘Yellow Berets’” and basically deals how a Doctor Draft made a positive impact on improving the basic research of clinical medicine. Professor Park received his Doctorate at Johns Hopkins University and came to KAIST in 2007. Summary of Dissertation From the start of the Korean War in 1950 to the end of the Vietnam War in 1973 a large number of medical school graduates were drafted to the army. Of those drafted, 100 personnel were chosen annually to focus on researching in the National Institute of Health who developed into leaders of the field. For example, those who worked as a researcher at the National Institute instead of their armed services were 1.5 times more likely to become a tenured professor, 2 times more likely to be promoted to Dean of the department, and 3 times more likely to be the Dean. In addition, 9 out of 50 Nobel Prize winners in fields of natural sciences between 1985 and 2007 were from the same pool of researchers, and 10 out of 76 recipients of National Medal of Science were also from the same pool of researchers. They were named the ‘Yellow Berets’ like the special forces ‘Green Berets’ and made great contribution to the field in implementing and executing the bench to beside culture that involves development in laboratories to clinical testing. Professor Park maintains that there has to be improvements made in current policies to encourage research work in medical graduate schools.

New Diagnosis System for Cardiovascular Disease Developed
Professor Park Hyun Kyu of the department of Biological-Chemical Engineering developed a new diagnosis system for diagnosing cardiovascular diseases using E.coli to test the homocysteine concentration in the blood. The research team used the genetic recombination process to produce two different biologically illuminant nutrition cultures and compared the growth rate of the homocysteine between the two cultures by comparing the degree of luminescence. The technology can allow the simultaneous analysis of blood samples en masse and is also economical and thus is being regarded as a major step forward in the field of homocysteine concentration analysis which is a rapidly growing field. The conventional method used high performance liquid chromatography which took a long time to complete and was costly to run. The advantage of the newly developed system is that it gets rid of costly steps as it only needs to grow E.coli and measure the luminescence of the naturally occurring illuminant. The research was published as the cover paper of the April edition of ‘Analytical Chemistry’.

Low Cost and Simple Gene Analysis Technology Developed
Professor Park Hyun Kyu of the Department of Biology and Chemical Engineering has developed a ‘real time CPR’ using Methylene Blue (nucleic acid bonding molecule with Electro-Chemical property). The current gene analysis being used in the field is the real time PCR (Polymerase Chain Reaction) which takes advantage of the luminescent property of the gene and therefore requires expensive machines and chemicals to run. By contrast, the electro-chemical method is easy to use and low cost and, most importantly, it allows the machine to become small and portable. Professor Park’s research team used the decrease in the electro-chemical signal when the Methylene Blue reacts with nucleic acid and applied this to PCR which allowed for the real time analysis of the nucleic acid amplification process. With the result of the experiment as the basis, the team was able to perform a trial with Chlamydia trachomatis, a pathogen that causes sexually transmitted disease. The result showed that the electro-chemical method showed the same performance level as the real time PCR, which proved that the technology can be applied to diagnosing various diseases and gene research.

Genetic Cause of ADHD (Attention Deficit Hyperactivity Disorder) Found
The cooperative research team consisting research teams under Professor Kim Eun Joon and Professor Kang Chang Won of the department of Biological Sciences discovered that ADHD arises from the deficiency of GIT1 protein in the brain’s neural synapses. ADHD (Attention Deficit Hyperactivity Disorder) is found in around 5% of children around the world and is a disorder where the child becomes unable to concentrate, show over the top responses, and display impulsive behavior. The research team found that the difference between children with ADHD and those without it is one base in the GIT1 gene. The difference of a single base causes the underproduction of this protein, and those children with low levels of the protein had a higher probability to develop ADHD. In addition, further evidence was provided when the research team conducted mice experiments. Those mice with low levels of GIT1 exhibited impulsive and exaggerated reactions like humans with ADHD, had learning disabilities, and produced abnormal brain waves. And upon injecting these mice with cure for ADHD, the symptoms of ADHD disappeared. The impulsive behavior of ADHD children disappears as the child enters adulthood and a similar pattern was found in mice. A mice with low levels of GIT1 showed impulsive behaviors when 2 months old, but these behaviors disappeared as it got older to around 7 months old (equivalent to 20~30 years old for humans). Professor Kim Eun Joon commented that there has to be equilibrium between mechanisms that excite the neurons and mechanisms that calm the neurons, but the lack of GIT1 leads to the decrease in the mechanisms that calm the neurons which causes the impulsive behavior of ADHD patients. In addition, Professor Kang Chang Won commented that the results of the experiment has been receiving rave reviews and is being seen as the new method in the production of the cure for ADHD. The result of the experiment was published in the online edition of Nature Medicine magazine.

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
Source: IDTechEX, Feb. 28, 2011 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." http://www.printedelectronicsworld.com/articles/kaist_paves_the_way_to_commercialize_flexible_display_screens_00003144.asp?sessionid=1
