Professor YongKeun Park Produces Undergraduate Students with International Achievements
Three undergraduate students under the supervision of Professor YongKeun Park from the Department of Physics, KAIST, have published papers in globally renowned academic journals.
The most recent publication was made by YoungJu Jo, a senior in physics. Jo’s paper entitled “Angle-resolved light scattering of individual rod-shaped bacteria based on Fourier transform light scattering” was published in the May 28th edition of Scientific Reports.
Analyzing bacteria is a very important task in the field of health and food hygiene, but using the conventional biochemical methods of analysis takes days. However, observation with Jo’s newly developed method using light scattering analyzes bacteria within a matter of seconds.
SangYeon Cho from the Department of Chemistry also published papers in Cell (2012) and Nature (2013), respectively, under the guidance of Professor Park. SangYeon Cho’s outstanding research achievements were recognized by Harvard and MIT. He was accepted with a full scholarship to Harvard-MIT Health Sciences and Technology Graduate School. He will begin his graduate studies at Harvard-MIT this September.
Last March, SeoEun Lee from the Department of Biology was the recipient of the Best Paper Award by the Optical Society of Korea. She plans to pursue a doctoral degree at the College of Physicians and Surgeons, Columbia University in New York.
Professor Park said, “Undergraduate students, who are learning a variety of subjects concurrently, are at the most creative time of their lives. KAIST has offered many opportunities to undergraduate students to partake in various research programs.”

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.

Technology Developed to Control Light Scattering Using Holography
Published on May 29th Nature Scientific Reports online
Recently, a popular article demonstrated that an opaque glass becomes transparent as transparent tape is applied to the glass. The scientific principle is that light is less scattered as the rough surface of the opaque glass is filled by transparent tape, thereby making things behind the opaque glass look clearer.
Professor Yong-Keun Park from KAIST’s Department of Physics, in a joint research with MIT Spectroscopy Lab, has developed a technology to easily control light scattering using holography. Their results are published on Nature’s Scientific Reports May 29th online edition.
This technology allows us to see things behind visual obstructions such as cloud and smoke, or even human skin that is highly scattering, optically thick materials. The research team applied the holography technology that records both the direction and intensity of light, and controlled light scattering of obstacles lied between an observer and a target image. The team was able to retrieve the original image by recording the information of scattered light and reflecting the light precisely to the other side.This phenomenon is known as “phase conjugation” in physics. Professor Park’s team applied phase conjugation and digital holography to observe two-dimensional image behind a highly scattering wall. “This technology will be utilized in many fields of physics, optics, nanotechnology, medical science, and even military science,” said Professor Park. “This is different from what is commonly known as penetrating camera or invisible clothes.” He nevertheless drew the line at over-interpreting the technology, “Currently, the significance is on the development of the technology itself that allows us to accurately control the scattering of light."

Waking Up Is Hard to Do: Scientists have discovered a new mechanism in the core gears of the circadian clock.
The US News & World Report released an article (Feb. 18, 2011) on KAIST’s research collaboration with Northwestern University in the US to identify a gene that regulates the rhythm of a fruit fly’s circadian clock, which may be applied to explain human’s sleep-wake cycle. The research result was published February 17 in the journal Nature.

Radical measures from the new president of the Korea Advanced Institute of Science and Technology are roiling a tradition-bound system

DAEJEON, SOUTH KOREA--When the Korea Advanced Institute of Science and Technology (KAIST) announced on 19 November that an entrepreneur had donated $2.5 million to the university with promises of more to follow, it marked the latest in a string of coups for the new president, Suh Nam Pyo. A mechanical engineer on leave from the Massachusetts Institute of Technology (MIT) in Cambridge, Suh has raised an unprecedented amount--$12.5 million--in a country where donations to universities are rare. He"s challenging other traditions as well. For example, KAIST"s latest tenure review turned down several candidates, a shocking move by Korean standards.Suh says he is aiming to make KAIST "as good as the best [universities], including MIT." Many faculty members agree that Suh"s "overall philosophy and vision are correct," says KAIST systems biologist Lee Sang Yup. But there are concerns about how Suh will implement that vision at the 36-year-old university.
The KAIST community has reason to be cautious. In 2004, the university hired Nobel physics laureate Robert Laughlin as president--the first foreigner to lead a Korean university--with a mandate to transform KAIST into a world-class institution. Laughlin, on leave from Stanford University in Palo Alto, California, proposed privatizing KAIST and charging tuition, focusing on commercialization, and tripling undergraduate enrollment (Science, 25 February 2005, p. 1181; 20 January 2006, p. 321). But when Laughlin"s plans failed to materialize, "the faculty was disappointed," says KAIST molecular biologist Chung Jongkyeong. In 2006, the board of trustees decided to seek a new president.
The board turned to Suh. Born in Gyeongju, South Korea, in 1936, Suh moved to the United States with his family as a teenager and earned a doctorate in mechanical engineering from Carnegie Mellon University in Pittsburgh, Pennsylvania. As an MIT professor, Suh has won plaudits for his engineering design theories, earned more than 50 patents, and helped start several companies. In the early 1980s, he was assistant director for engineering at the U.S. National Science Foundation, and he headed MIT"s Department of Mechanical Engineering from 1991 until 2001.
Since arriving at KAIST in July 2006, Suh has opened undergraduate education to non-Korean students for the first time by insisting that many courses be taught in English. Suh decided that students who maintain "B" or better grades would continue to pay no tuition, whereas those with a "C" or below must pay about $16,000 per year starting in February. "We want students to take responsibility for their actions," Suh says.

A new admissions process may also have broad impact. Previously, KAIST, like most of Korea"s top universities, selected the top scorers in a written exam. Most high school students spend their free time prepping for these tests in cram schools. But Suh says that scores "are a one-dimensional measure" that fails to identify leaders. So candidates for KAIST"s next incoming class were invited to campus this fall for interviews, to give presentations, and to engage in discussions while being observed by faculty members, who made selections based on scores and personal impressions. "We"re looking for future Einsteins and future Bill Gateses," says Suh.An even more radical step was putting teeth into tenure reviews. Traditionally, faculty members in Korea gain tenure after logging enough years. Suh insisted that KAIST professors up for tenure gather endorsements from experts in their field around the world. In September, 11 of 33 applicants were denied tenure and were given a year to find new jobs.
The tenure review "is the beginning of an educational revolution," says KAIST chemist Ryoo Ryong. But he and others worry about the fate of those denied tenure. Suh understands their predicament but is standing firm. The professors who didn"t make tenure "are very good people, but in terms of the standard we set, they"re not as good as we expect our professors to be." He is asking other universities to consider giving these professors a chance.
At the same time, Suh is looking to inject fresh blood--including foreigners--into the 418-strong faculty with a plan to add 300 professors over the next 4 to 5 years. (To expand the school, Suh is striving to win government approval for a doubling of KAIST"s base governmental support of $108 million.) His first catch is Mary Kathryn Thompson, who completed her Ph.D. in mechanical engineering at MIT last year. "It"s an exciting time to be here," says Thompson, who just started studying Korean when she arrived last August.
Although they support Suh"s initiatives, some faculty members chafe at his blunt public comments implying that Korea"s professors take life too easy. "I cannot agree," says Choi Yang-Kyu, an electrical engineer. "Most professors here are working very hard." Biomolecular engineer Kim Hak-Sung adds: "President Suh should have sticks and carrots, not just sticks."
Carrots don"t come cheap. "I"m spending most of my time trying to raise money," Suh says. Part of that effort is wooing private donors. "Giving to universities is not prevalent in Asia, but it is something I"m trying to nurture in Korea," he says. That"s a precedent all of Korea"s universities might want to embrace.
