Professor Son Hoon received "Structural Health Monitoring Person of the Year Award."
Professor Son Hoon (42) of the Department of Civil and Environmental Engineering received the “Structural Health Monitoring Person of the Year Award” at an international workshop on structural health monitoring held in Stanford University. The award is given by the editor and advisors of prestigious international magazine, “Journal of Structural Health Monitoring,” to a researcher with the best research record in a year. Professor Son has published 42 SCI level dissertations, registered 17 patents both domestically and internationally, and presented over 100 papers in international journals, for which he was recognized with the award. Professor Son is the first Korean who receives this award. One of the most significant achievements by Professor Son was “reference-free damage diagnosis” that he had developed in 2007. The diagnosis allows for the detection of wear and tear of a structure without having to use the foundation signal from the initial stages of the structure. The diagnosis contributed greatly in increasing the reliability of the signal information received from smart sensors attached to the structure by eliminating the environmental impact like temperature. Professor Son is currently working on green energy structural health monitoring system development related projects. His current work deals with airplanes, bridges, nuclear facilities, high speed railways, wind turbines, and etc. in cooperation with Boeing, United States Air Force Research Institute, Korea Research Foundation, Ministry of Defense Research Institute, Korea Expressway Corporation, POSCO, and etc. In addition, Professor Son successfully adopted a local monitoring method using smart piezoelectric sensors on a bridge in New Jersey as part of the Long Term Bridge Performance Program initiated by the National Highway Bureau. The success was even introduced in New Jersey’s public TV and newspaper agencies. Professor Son was given tenure at a record age of 39 in 2008 and received numerous awards given out by the Ministry of Education and Science and international organizations like the ‘Edward M Curtis’ Professor Award from Purdue University.

KAIST Research Team Unveils Method to Fabricate Photonic Janus Balls
A research team led by Prof. Seung-Man Yang of the Department of Chemical and Biomolecular Engineering has found a method to fabricate photonic Janus balls with isotropic structural colors. The finding draws attention since the newly-fabricated photonic balls may prove useful pigments for the realization of e-paper or flexible electronic displays. The breakthrough was published in the Nov. 3 edition of the science journal "Advanced Materials." The Nov. 6 issue of "Nature" also featured it as one of the research highlights under the title of "Future Pixels." Prof. Yang"s research team found that tiny marbles, black on one side and colored on the other, can be made by "curing" suspensions of silica particles with an ultraviolet lamp. When an electric field is applied, the marbles line up so that the black sides all face upwards, which suggests they may prove useful pigments for flexible electronic displays. The researchers suspended a flow of carbon-black particles mixed with silica and a transparent or colored silica flow in a resin that polymerizes under ultraviolet light. They then passed the mixture through a tiny see-through tube. The light solidified the silica and resin as balls with differently colored regions, each about 200 micrometers in diameter. Over the last decades, the development of industrial platforms to artificially fabricate structural color pigments has been a pressing issue in the research areas of materials science and optics. Prof. Yang, who is also the director of the National Creative Research Initiative Center for Integrated Optofluidic Systems, has led the researches focused on fabrication of functional nano-materials through the process of assembling nano-building blocks into designed patterns. The "complementary hybridization of optical and fluidic devices for integrated optofluidic systems" research was supported by a grant from the Creative Research Initiative Program of the Ministry of Education, Science & Technology.

KAIST Professor Exposes Structural Dynamics of Protein in Solution
-- Dr. Hyot-Cherl Ihee"s 3-Year Research Is Valuable in Pharmaceutical Application Prof. Hyot-Cherl Ihee and his team at the Department of Chemistry, KAIST, has successfully unveiled the structural dynamics of protein in solution as a result of more than three years" research work. Nature Methods, a sister publication of the authoritative science magazine Nature, published the treatise, titled "Tracking the structural dynamics of proteins in solution using time-resolved wide-angle X-ray scattering" in its Sept. 22 online edition. The research paper will be carried in the magazine"s printed version in its October edition, according to Dr. Lee who is its correspondence author. In May 2005, Prof. Ihee successfully photographed the structural dynamics of protein in solid state and his findings were published in the Proceedings of National Academy of Science of the United States. As protein normally exists in human body in solution, not in solid state, he directed his research to developing the technology to capture protein"s dynamics in resolved state. In July that year, Prof. Ihee succeeded in measuring the structural changes of simple organic molecules in real time. He further developed the technology to uncover the structural dynamics of hemoglobin, myoglobin and cytochrome C. Prof. Ihee"s research, helped with the Education-Science-Technology Ministry"s Creative Research Promotion Fund, can be applied to new pharmaceutical development projects as well as nanotechnology development, according to KAIST officials. Prof. Ihee who earned his doctorate at California Institute of Technology in 1994 began teaching at KAIST in 2003. He won the Young Scientist Award given by the Korean government in 2006.
