KAIST's OLEV Best Model of Creative Growth Engine
Various models of electric vehicles designed to replace the internal combustion automobiles face significant problems as they invariably failed to overcome the limitations involving lithium battery in terms of power capacity, weight, raw materal price, recharging time and preparation of charging stations. Worst of all, the limited supply of lithium will eventually raise its price sky high when all cars use lithium batteries, and the economic value of electric cars will be lost.
KAIST"s online electric vehicle project (OLEV) seeks to resolve these fundamental problems involving electric vehicles that have so far been developed. KAIST OLEV, a project to develop a new growth engine for the nation and lead the future of global automotive industry, is an entirely new concept: the electric vehicle picks up power from underground power supplier lines through the non-contact magnetic charging method, while either running or standing. This is the first eco-friendly and economic automotive system that can resolve the problems inherent to previously-developed electric vehicles, according to the KAIST OLEV Project Center.
In February 2009, KAIST researchers first proved that up to 80 percent power conveyance is possible through a gap of 1 centimeter from the power line, and in July they successfully supplied power to a bus -- up to 60 percent across a 12 cm gap from the power line embedded in the ground -- using power supply and pick-up devices they developed. In this process, KAIST has secured the core technologies for maximizing power efficiency and minimizing the cost of installing the non-contact power supply system. KAIST has established the Online Electric Vehicle Co., Ltd., to undertake business activities related to the OLEV project, including the IPR on power supply and pick-up devices, parts and accessories and commercial promotion. A demonstration event is scheduled for Aug. 13, Thursday.
The impact of the development of the OLEV technology on the energy and environment issues and the overall economy will be enormous. In case a half of the total automobiles running in Korea, or 6 million vehicles, are replaced with OLEV, electric power produced by just two of the nation"s atomic power plants will be enough to operate them all, and the nation will be able to reduce crude oil import by 35 million barrels worth U.S.$3 billion a year (supposing $80 per barrel).
Korea"s export of OLEV units will in the future surpass the present level of overseas sale of conventional cars. When nations use online electric vehicles in large numbers, their demand for CO2-free power plants will grow. Korea has cutting-edge technology in the construction of atomic power plants. As a world leader in the area of nuclear power plant, Korea will enjoy new opportunities to contribute to the global advancement of atomic power generation as well as transportation industries.
Korea still shares a small portion of the world"s automobile market estimated to worth some 2,000 trillion Korean won. But commercialization of the OLEV technology worldwide will greatly enhance Korea"s global automotive market share. Successful development of the online electric vehicle requires preemptive investment and positive support by the government for the ultimate purpose of resolving energy and environment problems.
If and when domestic enterprises secure technological supremacy in the next generation automobile market with their online electric vehicles which will replace the 100-year-old combustion engine, it will be the most desirable shortcut to raising Korea"s international competitiveness. OLEV promises to be the model of creative growth engine in the 21st century.

Five Prominent Figures Appointed as KAIST Admission Officers
KAIST appointed five celebrated figures including Seung Park, former Bank of Korea governor, as admission officers on May 15, university authorities said on Thursday (May 14).
The four others are Moon-Soul Chung, founder and former CEO of Mirae Corp., who is well known as the first-generation venture entrepreneur in Korea; In-ho Lee, former Korean ambassador to Russia; Myung-ja Kim, former minister of environment; and former KAIST President Chang-sun Hong who was a National Assemblyman.
Their appointment is designed to guarantee transparency and fairness in a new undergraduate admission system. KAIST has decided to select. 150 freshmen from among 1,000 students recommended by the principals of as many general high schools across the country. The five special admission officers will participate in interviewing the recommended students. The new screening system which is introduced to broaden the field of applicants to graduates from schools other than science high schools will be implemented from the next school year.
The newly appointed admission officers will have orientation sessions on May 28-29 and then visit high schools nationwide to interview the recommended students in June and July.
KAIST set off a new trend in the admission process when President Nam-Pyo Suh announced in March that 150 students, or about 16 percent of the freshmen enrollment, would be recruited from regular high schools solely on the basis of their principals" recommendation and interview results in March.
Award-winning records at math or science competitions will not be put into account in admissions to prevent after-school tutoring aimed at winning such contests. Unveiling the new admission plan, President Suh said, "We expect the principals to recommend students with special talents or potential rather than high grades."
Established under a special law in 1971, KAIST is given full liberty to recruit freshmen students in whatever method it deems right, without being required to use the scholastic ability test scores of applicants as the basic criteria.
The socially respected admission officers will single out 300 from among the 1,000 recommended students for further review. Out of the 300, the final 150 students will be chosen through in-depth interviews by KAIST professors.
"Through years of receiving principal"s recommendations and judging the academic records of the recommended students at KAIST, we can accumulate a database on high schools nationwide. If a student from a certain high school turns out to be no good, we might not pick any more student from that school," Suh said.
Over 80 percent of students admitted to KAIST this year were graduates of elite institutions, mostly science high schools. Only 20 percent came from regular high schools. Ten percent of the 150 additional openings for regular high school graduates will be alloted to students from rural areas and another 10 percent to low-income households.
"A certain high school was not able to send even a single student to KAIST for the last 10 years. I"m sure there are talented students in that school. If we give the school a chance, it wil help improve the education environment in this country," Suh said.

Prof. Cho Identifies Dynamics of Signal Transportation System in Control of Cell Proliferation
KAIST, Jan. 22, 2009 -- A research team led by Prof. Kwang-Hyun Cho of the Department of Bio and Brain Engineering, KAIST, has identified a hidden mechanism of the dynamic behavior of signal transportation system involved in the control of cell proliferation, university authorities said.
The finding is expected to provide a clue to appropriately controlling the pathway of ERK protein which is known to play a significant role in causing and spreading cancer. The research was featured as the cover paper of the latest online edition of the Journal of Cell Science.
The Ras-Raf-MEK-ERK pathway (or ERK pathway) is an important signal transduction system involved in the control of cell proliferation, survival and differentiation. However, the dynamic regulation of the pathway by positive- and negative-feedback mechanism, in particular the functional role of Raf kinase inhibitor protein (RKIP) are still incompletely understood. RKIP is a physiological endogenous inhibitor of MEK phosphorylation by Raf kinases, but also participates in a positive-feedback loop in which ERK can inactivate RKIP.
"We attempted to unearth the hidden dynamics of these feedback mechanisms and to identify the functional role of RKIP through combined efforts of biochemical experiments and computer simulations based on an experimentally validated mechanical model," Prof. Cho was quoted as saying.

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.
