ASPIRE League 2014: E-Olympics among Five Asian Universities
About 150 undergraduate students from five leading science and technology (S&T) universities in Asia met at the KAIST campus to attend the E-Olympics on August 7-9, 2014.
The E-Olympics began as a student exchange conference held under the Asian Science and Technology Pioneering Institutes of Research and Education (ASPIRE) League, which offers a variety of events, such as workshops, sports matches, lab visits, special lectures, and art performances, to promote academic and research collaborations and cultural sharing between the students of the league member universities.
Founded in 2009, the ASPIRE League is a university consortium consisted of five top S&T universities in Asia: KAIST in Korea, the Hong Kong University of Science and Technology (HKUST) and Tsinghua University in China, Nanyang Technological University (NTU) in Singapore, and Tokyo Institute of Technology (Tokyo Tech) in Japan. The ASPIRE League aims to provide a knowledge and technology hub for innovation in Asia through the advancement of science and technology and the development of human resources.
Since its start, the ASPIRE League has been holding an annual conference with programs for research collaboration, student exchange, educational cooperation, and satellite laboratories among professors, senior managers, and students of the member universities. This year, however, the consortium decided to dedicate the conference to students by holding the E-Olympics.
Each university sent 30 students to KAIST for the participation of the E-Olympics. For three days, participating students engaged in discussions and presentations at academic workshops; held athletic games including a relay race, basketball, and a rowing race; and toured a few KAIST laboratories, among them: the E-mobility Research Center, the Bio-imaging and Cell Signaling Research Center, the Mechatronics Systems and Control Center, and the Center of Field Robotics for Innovation, Exploration and Defense.
The students also attended a music concert performed by a KAIST student club and a lecture entitled “Entrepreneurship through Global Networking” that emphasized the importance of personnel networking in transferring technological innovation into business opportunities.
Chang-Dong Yoo, the Dean of the International Office at KAIST, said, “The E-Olympics will offer students from top science and technology universities in Asia opportunities to interact with each other on a more personal level. I hope that through many of the E-Olympics programs, the students will learn about each other’s culture and academic strength and develop a sense of community to create a “New Asia” by working together.”

First Instance of Negative Effects from Terahertz-Range Electromagnetic Waves
Professor Philhan Kim
Electromagnetic waves (EM-wave) in the terahertz range were widely regarded as the “dream wavelength” due to its perceived neutrality. Its application was also wider than X-rays. However, KAIST scientists have discovered negative effects from terahertz EM-waves.
Professor Philhan Kim of KAIST’s Graduate School of Nanoscience and Technology and Dr. Young-wook Jeong of the Korea Atomic Energy Research Institute (KAERI) observed inflammation of animal skin tissue when exposed to terahertz EM-waves.
The results were published in the online edition of Optics Express (May 19, 20104).
Terahertz waves range from 0.1 to 10 terahertz and have a longer wavelength than visible or infrared light. Commonly used to see through objects like the X-ray, it was believed that the low energy of terahertz waves did not inflict any harm on the human body.
Despite being applied for security checks, next-generation wireless communications, and medical imaging technology, little research has been conducted in proving its safety and impact. Conventional research failed to predict the exact impact of terahertz waves on organic tissues as only artificially cultured cells were used.
The research team at KAERI developed a high power terahertz EM-wave generator that can be used on live organisms. A high power generator was necessary in applications such as biosensors and required up to 10 times greater power than currently used telecommunications EM-wave. Simultaneously, a KAIST research team developed a high speed, high resolution video-laser microscope that can distinguish cells within the organism.
The experiment exposed 30 minutes of terahertz EM-wave on genetically modified mice and found six times the normal number of inflammation cells in the skin tissue after six hours. It was the first instance where negative side effects of terahertz EM-wave were observed.
Professor Kim commented that “the research has set a standard for how we can use the terahertz EM-wave safely” and that “we will use this research to analyze and understand the effects of other EM-waves on organisms.”

Clear Display Technology Under Sunlight Developed
The late Professor Seung-Man Yang
The last paper of the late Professor Seung-Man Yang, who was a past master of colloids and fluid mechanics
Practical patterning technology of the next generation optical materials, photonic crystals
The mineral opal does not possess any pigments, but it appears colorful to our eyes. This is because only a particular wavelength is reflected due to the regular nano-structure of its surface. The material that causes selective reflection of the light is called photonic crystals.
The deceased Professor Seung-Man Yang and his research team from KAIST’s Chemical and Biomolecular Engineering Department ha ve developed micro-pattern technology using photolithographic process. This can accelerate the commercialization of photonic crystals, which is hailed as the next generation optics material.
The research results were published in the April 16th edition of Advanced Materials, known as the most prestigious world-renowned journal in the field of materials science.
The newly developed photonic crystal micro-pattern could be used as a core material for the next generation reflective display that is clearly visible even under sunlight. Since it does not require a separate light source, a single charge is enough to last for several days.
Until now, many scientists have endeavored to make photonic crystals artificially, however, most were produced in a lump and therefore lacked efficiency. Also, the low mechanical stability of the formed structure prevented from commercialization.
In order to solve these problems, the research team has copied the nano-structure of opals.
Glass beads were arranged in the same nano-structure as the opal on top of the photoresist material undergoing photocuring by ultraviolet light. The glass beads were installed in the photoresist materials, and UV light was selectively exposed on micro regions. The remaining region was developed by photolithographic process to successfully produce photonic crystals in micro-patterns.
The co-author of the research, KAIST Chemical and Biomolecular Engineering Department’s Professor Sin-Hyeon Kim, said, “Combining the semiconductor process technology with photonic crystal pattern technology can secure the practical applications for photonic crystals.”He also predicted “This technology can be used as the key optical material that configures the next generation reflective color display device with very low power consumption.”
The late Professor Seung-Man Yang was a world-renowned expert in the field of colloids and fluid mechanics. Professor Yang published over 193 papers in international journals and continued his research until his passing in last September.
He received Du Pont Science and Technology Award in 2007, KAIST Person of the Year 2008, Gyeong-Am Academy Award in 2009, as well as the President’s Award of the Republic of Korea in March 2014. The researchers devoted the achievement of this year’s research to Professor Yang in his honor.
Research was conducted by KAIST Photonic-fluidic Integrated Devices Research Team, as a part of the Creative Research Program funded by the Ministry of Science, ICT and Future Planning, Republic of Korea.

High Resolution 3D Blood Vessel Endoscope System Developed
Professor Wangyeol Oh of KAIST’s Mechanical Engineering Department has succeeded in developing an optical imaging endoscope system that employs an imaging velocity, which is up to 3.5 times faster than the previous systems. Furthermore, he has utilized this endoscope to acquire the world’s first high-resolution 3D images of the insides of in vivo blood vessel.
Professor Oh’s work is Korea’s first development of blood vessel endoscope system, possessing an imaging speed, resolution, imaging quality, and image-capture area. The system can also simultaneously perform a functional imaging, such as polarized imaging, which is advantageous for identifying the vulnerability of the blood vessel walls.
The Endoscopic Optical Coherence Tomography (OCT) System provides the highest resolution that is used to diagnose cardiovascular diseases, represented mainly by myocardial infarction.
However, the previous system was not fast enough to take images inside of the vessels, and therefore it was often impossible to accurately identify and analyze the vessel condition. To achieve an in vivo blood vessel optical imaging in clinical trials, the endoscope needed to be inserted, after which a clear liquid flows instantly, and pictures can be taken in only a few seconds.
The KAIST research team proposed a solution for such problem by developing a high-speed, high-resolution optical tomographic imaging system, a flexible endoscope with a diameter of 0.8 mm, as well as a device that can scan the imaging light within the blood vessels at high speed. Then, these devices were combined to visualize the internal structure of the vessel wall.
Using the developed system, the researchers were able to obtain high-resolution images of about 7 cm blood vessels of a rabbit’s aorta, which is similar size to human’s coronary arteries. The tomography scan took only 5.8 seconds, at a speed of 350 scans per second in all three directions with a resolution of 10~35㎛.
If the images are taken every 200 ㎛, like the currently available commercial vascular imaging endoscopes, a 7cm length vessel can be imaged in only one second.
Professor Wangyeol Oh said, “Our newly developed blood vessel endoscope system was tested by imaging a live animal’s blood vessels, which is similar to human blood vessels. The result was very successful.”
“Collaborating closely with hospitals, we are preparing to produce the imaging of an animal’s coronary arteries, which is similar in size to the human heart,” commented Professor Oh on the future clinical application and commercialization of the endoscope system. He added, “After such procedures, the technique can be applied in clinical patients within a few years.”
Professor Oh’s research was supported by the National Research Foundation of Korea and the Global Frontier Project by the Korean government. The research results were published in the 2014 January’s edition of Biomedical Optics Express.

Visit by Sir Paul Maxime Nurse, President of the Royal Society
Sir Paul Maxime
Nurse, who is an English geneticist and cell biologist, visited KAIST and gave
a lecture entitled The Great Ideas of
Biology on March 11, 2014.
Sir Paul was awarded the 2001 Nobel Prize in
Physiology or Medicine with Leland H. Hartwell and R. Timothy Hunt for their discoveries
of protein molecules that control the division of cells in the cell cycle.
He was Professor of Microbiology at the University
of Oxford, CEO of the Imperial Cancer Research Fund and Cancer Research UK, and
President of Rockefeller University in New York. Sir Paul is currently the President of
the Royal Society as well as Director and Chief Executive of the Francis Crick
Institute.
Founded in London in 1660, the Royal Society is composed of the world’s most distinguished scientists drawn from all areas of
science, engineering, and medicine.
Below is a summary of his lecture, The Great Ideas of Biology:
Four major ideas of biology
are the theory of genes, evolution by natural selection, the proposal that the
cell is the fundamental unit of all life, and the chemical composition of a cell.
When considering the
question “what is life?” these ideas come together. The special way cells reproduce
provides the conditions by which natural selection takes place, allowing living
organisms to evolve. The organization of chemistry within the cell provides
explanations for life’s phenomena.
In addition, an emerging idea
is the nature of biological self-organization with which living cells and organisms
process information and acquire specific forms. These great ideas have
influenced one another and changed the way we perceive biology and science
today.

Festival Featuring Asia's Best Science Students to be Held
The first Electronic Olympics, which will host students from five top Asian research-centered universities, will be held in August at KAIST. Students will take part in competitive events and explore cultural diversity. Student representatives of HKUST, NTU, TITECH, Tsinghua University, and KAIST gathered on February 20 to begin planning the tentatively named “ASPIRE E-Olympics.”
The key words of this Olympics are "Harmony" and "Competition." The events will be composed of an AI programming contest, SEM (Scanning Electron Microscope) picture contest, and the other technology-based contests. Cultural events, where each university’s students can interact, will also be prepared.
ASPIRE (Asian Science and Technology Pioneering Institutes of Research and Education) events have been held from 2009. Previously, the ASPIRE forum has been an exchange event for groups of vice presidents and graduate school students from the five schools to exchange achievements in education and research. This year, it has been extended to undergraduates.
Yoseop Kim, KAIST’s student body vice president, said that he wants to make a MOU with some of Asia’s best research-centered universities and develop it into something similar to the Davos Forum. His intention is to support the E-Olympics in the hope that ASPIRE will become a top university consortium.

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.
