OLEV Safety Confirmed by International Standards
On September 19, KAIST announced that the electromagnetic (EM) field levels of its online electric vehicle (OLEV) measured in June and September of this year demonstrated verification of its safety.
Last June, the EM field level of OLEV installed at the Seoul Grand Park was measured by the Korea Research Institute of Standards and Science (KRISS) to test its harmfulness to human. The results were 0.5 ~ 61mG which is within the national and international standards of 62.5mG.
KRISS measured EM field levels on 22 spots on the side of and at the center of OLEV at a fixed distance (30cm) but variable heights (5cm~150cm) according to the national standard of measurement methods for electromagnetic fields of household appliances and similar apparatuses with regard to human exposure (IEC 62233).
In addition, another testing took place on September 13 following a request by National Assemblywoman Young-Ah Park, a member of the National Assembly’s Education, Science and Technology Committee, who has raised an issue on the safety of OLEV. This testing session was held by EMF Safety, Inc., an institution designated by Park, and it tested the EM field level of the same OLEV train that was tested in June.
As a result, the September measurements were well within the national and international standards with 0~24.1mG. The test was conducted under the presence of third party to produce a fair and objective result.
As reference, the EM field level results are well within the American IEEE electromagnetic field standards of 1,100 mG.
The September measurements were produced by Park’s recommendation of following the criteria specified in the measurement procedures of IEC 62110, “Electric and magnetic field levels generated by AC power systems to public exposure,” which were 15 measurements at a fixed 20cm distance at the side of and from the center of OLEV with variable heights of 50cm~150cm.

Nature Photonics, a peer-reviewed scientific journal, released a paper written by a KAIST research team on the time-of-flight measurement.
Professor Seung-Woo Kim of the Mechanical Engineering Department, KAIST, and his research team published the result of their study on the measurement of 1 nanometer (nm) precision.
“The time-of-flight of light pulses has long been used as a direct measure of distance, but state-of-the-art measurement precision using conventional light pulses or microwaves peaks at only several hundreds of micrometers. Here, we improve the time-of-flight precision to the nanometer regime by timing femtosecond pulses through phase-locking control of the pulse repetition rate using the optical cross-correlation technique,” Professor Kim said.
According to the experiment conducted by the research team, “An Allan deviation of 117 nm in measuring a 700m distance in air at a sampling rate of 5 millisecond (ms) once the pulse repetition is phased-locked, which reduces to 7 nm as the averaging time increases to 1 second (s).”
When measuring an object located in a far distance, a laser beam is projected to the object, and the reflected light is analyzed; the light is then converted into an electric signal to calculate the distance. In so doing, Professor Kim said, the conventional method of measurement creates at least 1 mm of deviation.
He argues, “This enhanced capability is maintained at long range without periodic ambiguity, and is well suited to lidar applications. This method could also be applied to future space missions involving formation-flying satellites for synthetic aperture imaging and remote experiments related to general relativity theory."
Nature Photonics published the article online on August 8, 2010.

Bioengineers develop a new strategy for accurate prediction of cellular metabolic fluxes
A team of pioneering South Korean scientists has developed a new strategy for accurately predicting cellular metabolic fluxes under various genotypic and environmental conditions. This groundbreaking research is published in the journal Proceedings of the National Academy of Sciences of the USA (PNAS) on August 2, 2010.
To understand cellular metabolism and predict its metabolic capability at systems-level, systems biological analysis by modeling and simulation of metabolic network plays an important role. The team from the Korea Advanced Institute of Science and Technology (KAIST), led by Distinguished Professor Sang Yup Lee, focused their research on the development of a new strategy for more accurate prediction of cellular metabolism.
“For strain improvement, biologists have made every effort to understand the global picture of biological systems and investigate the changes of all metabolic fluxes of the system under changing genotypic and environmental conditions,” said Lee. The accumulation of omics data, including genome, transcriptome, proteome, metabolome, and fluxome, provides an opportunity to understand the cellular physiology and metabolic characteristics at systems-level. With the availability of the fully annotated genome sequence, the genome-scale in silico (means “performed on computer or via computer simulation.”) metabolic models for a number of organisms have been successfully developed to improve our understanding on these biological systems. With these advances, the development of new simulation methods to analyze and integrate systematically large amounts of biological data and predict cellular metabolic capability for systems biological analysis is important.
Information used to reconstruct the genome-scale in silico cell is not yet complete, which can make the simulation results different from the physiological performances of the real cell. Thus, additional information and procedures, such as providing additional constraints (constraint: a term to exclude incorrect metabolic fluxes by restricting the solution space of in silico cell) to the model, are often incorporated to improve the accuracy of the in silico cell.
By employing information generated from the genome sequence and annotation, the KAIST team developed a new set of constraints, called Grouping Reaction (GR) constraints, to accurately predict metabolic fluxes. Based on the genomic information, functionally related reactions were organized into different groups. These groups were considered for the generation of GR constraints, as condition- and objective function- independent constraints. Since the method developed in this study does not require complex information but only the genome sequence and annotation, this strategy can be applied to any organism with a completely annotated genome sequence.
“As we become increasingly concerned with environmental problems and the limits of fossil resources, bio-based production of chemicals from renewable biomass has been receiving great attention. Systems biological analysis by modeling and simulation of biological systems, to understand cellular metabolism and identify the targets for the strain improvement, has provided a new paradigm for developing successful bioprocesses,” concluded Lee. This new strategy for predicting cellular metabolism is expected to contribute to more accurate determination of cellular metabolic characteristics, and consequently to the development of metabolic engineering strategies for the efficient production of important industrial products and identification of new drug targets in pathogens.”

President Nam Pyo Suh of KAIST discussed cooperation with KUSTAR on the training of skilled manpower for research and development (R&D)
Representatives from Korea Advanced Institute of Science and Technology (KAIST), Khalifa University of Science, Technology and Research (KUSTAR), Emirate Nuclear Energy Corporation (ENEC), and the Institute of Applied Technology (IAT) had a meeting on mutual cooperation at the Intercontinental Hotel in Abu Dhabi, the United Arab Emirates (UAE), on January 14, 2009.
Participants of the meeting were President Nam Pyo Suh of KAIST, President Arif Sultan Al Hammadi of KUSTAR, President Mohamed Al Hammadi of ENEC, and Director General Abdullatif Mohamed Al Shamsi of IAT.
A press conference on the training of skilled manpower for research and development (R&D) in the UAE followed afterwards.
At the end of December in 2009, a Korean consortium led by Korea Electric Power Corporation (KEPCO) beat bids from its competitors to construct four nuclear power plants in the UAE. Representing the consortium, Minister Kyung Hwan Choi of Knowledge Economy Ministry signed a comprehensive agreement with KUSTAR and the Institute of Applied Technology (IAT) for the delivery of nuclear power plants.
On his visit, President Suh discussed with KUSTAR the agreement above in greater detail on subjects, where KAIST renders its cooperation, such as research collaboration, university degree program, and training to produce qualified personnel necessary for the development of UAE’s nuclear energy industry.
On research collaboration, sharing its expertise and knowledge accumulated years from the operation of academic and research programs, KAIST agreed to provide cooperation to KUSTAR in developing the latter as a leading science, technology, and research university in ten years through mutual activities such as research collaborations, recruitment and exchange of outstanding researchers and graduate students, expansion of research facilities, and creation of major research policies. Furthermore, in support of nuclear energy program in the UAE, KAIST agreed to develop a joint research program in nuclear engineering and exchange faculty members and students for research collaboration.
On a university degree program, KAIST agreed for mutual cooperation to launch academic programs at KUSTAR, covering BSc, MSc, and PhD degrees to specialize in areas such as mechanical engineering, electrical engineering, nuclear engineering, biomedical engineering, nano technology, science, and information technology. To that end, KAIST will dispatch its faculty to KUSTAR; provide assistance in developing curriculum and teaching materials; and exchange students for research collaboration.
President Arif of KUSTAR mentioned that the university will cooperate with the relevant institutions in Korea, i.e., Korea Development Institute (KDI) and the Korea Institute of Nuclear Safety (KINS), to train skilled workers required for the development of nuclear energy program in the UAE.
He also added, “These cooperative programs will introduce more educational opportunities to our students, and as a result, they can make greater contributions to the development of our nation’s future technologies in various areas. Our students will have a chance to study a broad range of academic subjects through partnership made with the Republic of Korea, and I expect to see improvements in our engineering programs by integrating KAIST’s state-of-the-art academic courses into our system.”
President Arif expressed his hope “to increase cooperation beyond the agreement made between the two countries, like allowing more exchanges and interactions with KAIST for the development of science and technology in Korea and the UAE.”
“Establishing mutual cooperation between KAIST and KUSTAR is a historic event not only for our two universities but also for our two countries. The two universities will make a great contribution to the improvement of the future of humanity by working together to solve the most important, difficult issues faced in the 21st century,” said President Suh.
He also said that “all members of KAIST community will make our utmost efforts to advance the quality of education in two schools and to implement innovative researches through mutual cooperation.”
KUSTAR, a national university in the UAE, was founded on February 13, 2007 by a mandate of the current President Shaikh Khalifa Bin Zayed Al Nahyan to create a higher education institute.
KUSTAR has been building its permanent campus in Abu Dhabi, the capital of UAE since establishment and merged with the campus in Sharjah (formerly known as Etisalat University College with 18 years of history) in 2008. The University offers education and research programs in five disciplines of engineering, logistics and management, health science, homeland security, and applied science.
There are more or less 30 foreign accredited universities set up in the UAE from countries like the US, UK, Australia, France, Ireland, and Canada. Examples of such, among other things, are New York University Abu Dhabi campus and Middlesex University Dubai campus.
Many of the foreign universities in the UAE, however, have colleges of pharmacy, computer science, aviation, management information, fashion design, business management, and medical science including Harvard Medical School Dubai Center, but not many in science and research. Therefore, KAIST’s assistance in KUSTAR’s endeavor to become a leading science and research university in the UAE is timely. The current government of UAE anticipates, with a great interest, to see a leading science and research intuition built in their nation.

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.

Storing Stably Hydrogen Atoms in Icy Materials Discovered
KAIST, Aug. 8, 2008 -- A KAIST research team led by Prof. Huen Lee of the Department of Chemical & Biomolecular Engineering has discovered that icy organic hydrates, which contain small cages that can trap guest molecules, can be used to create and trap hydrogen atoms at higher temperatures.
The properties and reactions of single hydrogen atoms are of great scientific interest because of their inherent quantum mechanical behavior; experimentally, they can be generated and stabilized at very low temperatures (4 K) by high-energy irradiation of solid molecular hydrogen.
The finding was reported in the journal of American Chemical Society and featured in the "Editor"s Choice" in the July 11 issue of Science as a recent research highlight.
Hydrogen is a clean and sustainable form of energy that can be used in mobile and stationary applications. Hydrogen has the potential to solve several major challenges today: depletion of fossil fuels, poor air quality, and green house gas emissions.
However, the trapping of hydrogen atoms in crystalline solid matrix has never been attempted mainly because of experimental difficulties in identifying the generated hydrogen atoms with either spectroscopic or microscopic technique.
"To overcome the barriers and limitations of the existing storage approaches, we have continuously attempted to find the new hydrogen storage media such as icy powders and other related inclusion compounds," said Prof. Lee
The discovery follows the breakthrough concept Prof. Lee"s research team proposed in Nature in 2005 to use pure ice to capture and store hydrogen molecules. At moderate temperature and pressure conditions small guest molecules are entrapped in pure ice powders to form the mixed icy hydrate materials.
"Stable existence of single hydrogen molecule/radical in icy crystalline matrices may offer significant advantages in exploring hydrogen as a quantum medium because icy hydrogen hydrates can be formed at milder conditions when compared with pure solid hydrogen, which requires the ultra low temperature of 4.2 K," said Prof. Lee.
The novel design and synthesis of ionic and radicalized icy hydrates are expected to open a new field for inclusion chemistry and ice-based science and technology. Specifically, the fact that hydrogen atoms can be stably stored in icy materials might provide versatile and practical applications to energy devices including fuel cells, ice-induced reactions, and novel energy storage process, according to the KAIST professor.
