A game enthusiast received a Ph.D. at the 2014 commencement
A high school student, who was addicted to video gaming and had barely managed to gain entrance to KAIST, became a star of its 2014 commencement ceremony.
The student was Tae-Woo Park who received his Ph.D. in games at 32 years of age.
Park entered KAIST in 2002 as an undergraduate student. However, owning to bad grades, he was not accepted to the graduate school of KAIST until 2006. He began playing games at the age of 7, which distracted him from his studies at an early age. Nevertheless, he was able to complete master’s degree after two and a half years, which normally takes two years for average students.
Professor Joon-Hwa Song saw a possibility from his student’s experience of producing and commercializing a mobile puzzle game while Park was working as a president of the game club, HAJE, at KAIST. Professor Song advised him to take the advantage of his interests and try developing game platforms and contents. Park decided to develop a game that could help others and would change people’s negative views of games. He created a whole new generation of games.
In order to find ideas for games that can be easily enjoyed in daily lives, Park went to numerous gyms, swimming pools, daycare centers, and parks to analyze people’s behaviors and discussed with his colleagues who were also interested in games. During this process, the experience of organizing creative ideas through cooperation and discussions became a great foundation for his future research.
He observed some people quitting midway during a workout on treadmills because they were bored with working out alone. From this, Park embarked on developing a new style of game that allowed people to exercise together.
Park used the system on a treadmill, which recognizes the speed of the person running to automatically adjust the machine’s speed, to develop an interactive game platform for Swan Boat. The Swan Boat game is a race exercise game that adjusts the direction according to speed difference between two players. The game utilizes the difference of running speed between two people on treadmills to change the direction of the boat.
With the Swan Boat game, people can now play games and exercise at the same time. The technology also allows online access anywhere in the world, which means checking friends’ rankings at nearby gyms or homes, or even a World Gym Running Contest.
In addition, Park helped develop various next generation exercise games and life-based services, including the sparrow chirp application, which finds children that go astray, or an avatar game that utilizes the user’s daily life patterns. These results and papers attracted attention from international societies and have also won a number of awards.
Professor Song said, “There has been no precedent of receiving a Ph.D. at KAIST for developing games, however, Park’s case has given courage to many people that if you can create what is really required in everyday life, you can indeed receive a doctor’s degree.”
Park remarked, “I’d like to express my gratitude to my advisor, Professor Song, for giving me courage. I want to continue to make games that can help people’s lives in the future.”
Park will continue his work at the NASA Ames Research Center this June.

Biomimetic Carbon Nanotube Fiber Synthesis Technology Developed
The byssus of the mussel allows it to live in harsh conditions where it is constantly battered by crashing waves by allowing the mussel to latch onto the seaside rocks. This particular characteristic of the mussel is due to the unique structure and high adhesiveness of the mussel’s byssus.
KAIST’s Professor Hong Soon Hyung (Department of Material Science and Engineering) and Professor Lee Hae Shin (Department of Chemistry) and the late Professor Park Tae Kwan (Department of Bio Engineering) were able to reproduce the mussel’s byssus using carbon nanotubes.
The carbon nanotube, since its discovery in 1991, was regarded as the next generation material due to its electrical, thermal, and mechanical properties. However due to its short length of several nanometers, its industrial use was limited.
The KAIST research team referred to the structure of the byssus of the mussel to solve this problem.
The byssus is composed of collagen fibers and Mefp-1 protein which are in a cross-linking structure. The Mefp-1 protein has catecholamine that allows it to bind strongly with the collagen fiber.
In the artificial structure, the carbon nanotube took on the role of the collagen fibers and the macromolecular adhesive took on the role of the catecholamine. The result was a fiber that was ultra-light and ultra-strong.
The results of the experiment were published in the Advanced Materials magazine and is patent registered both domestically and internationally.

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.

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.

Explanation for the polymerized nucleic acid enzyme's abnormal activation found
KAIST’s Professor Park Hyun Kyu of the Department of Bio Chemical Engineering revealed on the 23rd of December 2010 that his team had successfully developed the technology that uses the metal ions to control the abnormal activation of nucleic acids’ enzymes and using this, created a logic gate, which is a core technology in the field of future bio electrons.
The polymerized nucleic acid enzyme works to increase the synthesis of DNA and kicks into action only when the target DNA and primers form complimentary pairs (A and T, C and G).
Professor Park broke the common conception and found that it is possible for none complimentary pairs like T-T and C-C to initiate the activation of the enzyme and thus increase the nucleic acid production, given that there are certain metal ions present.
What Professor Park realized is that the enzymes mistake the uncomplimentary T-T and C-C pairs (with stabilized structures due to the bonding with mercury and silver ions) as being complimentary base pairs. Professor Park described this phenomenon as the “illusionary polymerase activity.”
The research team developed a logic gate based on the “illusionary polymerase activity’ phenomenon.” The logic gate paves the way to the development of future bio electron needed for bio computers and high performance memories.
Professor Park commented, “The research is an advancement of the previous research carried on about metal ions and nucleic acid synthesis. Our research is the first attempt at merging the concepts of the two previously separately carried out researches and can be adapted for testing presence of metal ions and development of a new single nucleotide polymorphic gene analysis technology.”
Professor Park added that, “Our research is a great stride in the field of nano scale electron element research as the results made possible the formation of accurate logic gates through relatively cost efficient and simple system designs.”
On a side note, the research was funded by Korea Research Foundation (Chairman: Park Chan Mo) and was selected as the cover paper for the December issue of ‘Angewandte Chemie International Edition’.
