IMMEDIATE RELEASE
Wireless electric trams at Seoul Amusement Park begin full operations.
KAIST’s On-Line Electric Vehicle (OLEV) becomes an icon of green technology, particularly for young students who aspire to transform their nation into the “vanguard of sustainability.”
Seoul, South Korea, July 19, 2011—As young students wrap up their school work before summer vacation in late July, Seoul Grand Park, an amusement park located south of Seoul, is busily preparing to accommodate throngs of summer visitors. Among the park’s routine preparations, however, there is something new to introduce to guests this summer: three wireless electric trams have replaced the old diesel-powered carts used by passengers for transportation within the park.
The Korea Advanced Institute of Science and Technology (KAIST) and the city of Seoul held a ceremony this morning, July 19, 2011, to celebrate their joint efforts to adopt a green public transportation system and presented park visitors with the three On-Line Electric Vehicles (OLEVs), which will be operated immediately thereafter. Approximately one hundred people, including science high school students across the nation, attended the ceremony and had a chance to ride the trams.
KAIST unveiled the prototype of an electric tram to the public in March 2010, and since then it has developed three commercial trams. The Korean government and the institute have worked on legal issues to embark on the full-scale commercialization of OLEV, and the long awaited approval from the government on such issues as standardization of the OLEV technology and road infrastructure, regulation of electromagnetic fields and electricity safety, and license and permits for vehicle eligibility, finally came through.
The On-Line Electric Vehicle (OLEV) is no ordinary electric car in that it is remotely charged via electromagnetic fields created by electric cables buried beneath the road. Unlike other currently available electric cars, OLEV can travel unlimited distances without having to stop to recharge. OLEV also has a small battery onboard, which enables the vehicle to travel on roads that are not equipped with underground power cables. This battery, however, is only one-fifth of the size of a conventional electric vehicle battery, resulting in considerable savings in the cost, size, and weight of the vehicle.
The OLEV project was initiated in 2009 as a method of resolving the battery problems of electric cars in a creative and disruptive way. KAIST came up with the idea of supplying electricity directly to the cars instead of depending solely on the onboard battery for power. Since then, the university has developed core technologies related to OLEV such as the “Shaped Magnetic Field in Resonance (SMFIR),” which enables an electric car to collect the magnetic fields and convert them into electricity, and the “Segment Technology,” which controls the flow of electromagnetic waves through an automatic power-on/shut-down system, thereby eliminating accidental exposure of the electromagnetic waves to pedestrians or non-OLEV cars.
According to KAIST, three types of OLEV have been developed thus far: electric buses, trams, and sport utility vehicles (SUVs). The technical specifications of the most recently developed OLEV (an electric bus), the OLEV research team at the university said, are as follows:
· Power cables are buried 15cm beneath the road surface.
· On average, over 80% power transmission efficiency is achieved.
· The distance gap between the road surface and the underbody of the vehicle is 20cm.
· The OLEV bus has a maximum electricity pickup capacity of 100kW.
· The OLEV bus complies with international standards for electromagnetic fields (below 24.1 mG).
The eco-friendly electric trams at Seoul Grand Park consume no fossil fuels and do not require any overhead wires or cables. Out of the total circular driving route (2.2km), only 16% of the road, 372.5m, has the embedded power lines, indicating that OLEV does not require extensive reconstruction of the road infrastructure. The city government of Seoul signed a memorandum of understanding with KAIST in 2009 as part of its initiatives to curtail emissions from public transportation and provide cleaner air to its citizens. Both parties plan to expand such collaboration to other transportation systems including buses in the future.
KAIST expects the OLEV technology to be applied in industries ranging from transportation to electronics, aviation, maritime transportation, robotics, and leisure. There are several ongoing international collaborative projects to utilize the OLEV technology for a variety of transportation needs, such as inner city commute systems (bus and trolley) and airport shuttle buses, in nations including Malaysia, US, Germany, and Denmark.

Research Conducted on the Development Policy of Medical Researchers in United States
The topic dealt in the paper was “The Vietnam War and Medical Research: Untold Legacy of the U.S. Doctor Draft and the NIH ‘Yellow Berets’” and basically deals how a Doctor Draft made a positive impact on improving the basic research of clinical medicine.
Professor Park received his Doctorate at Johns Hopkins University and came to KAIST in 2007.
Summary of Dissertation
From the start of the Korean War in 1950 to the end of the Vietnam War in 1973 a large number of medical school graduates were drafted to the army. Of those drafted, 100 personnel were chosen annually to focus on researching in the National Institute of Health who developed into leaders of the field.
For example, those who worked as a researcher at the National Institute instead of their armed services were 1.5 times more likely to become a tenured professor, 2 times more likely to be promoted to Dean of the department, and 3 times more likely to be the Dean. In addition, 9 out of 50 Nobel Prize winners in fields of natural sciences between 1985 and 2007 were from the same pool of researchers, and 10 out of 76 recipients of National Medal of Science were also from the same pool of researchers.
They were named the ‘Yellow Berets’ like the special forces ‘Green Berets’ and made great contribution to the field in implementing and executing the bench to beside culture that involves development in laboratories to clinical testing.
Professor Park maintains that there has to be improvements made in current policies to encourage research work in medical graduate schools.

World?'s First Automated Maritime-Docking between Naval Vessels
KAIST demonstrated the technology that allows automated maritime docking between naval vessels on the 26th of April at Busan, Korea.
The docking technology is seen as one of the key components for the mobile harbor as it prevents collision between two naval vessels upon docking. It was recognized as an important technology worldwide, but its technological limitations made it hard to commercialize.
The demonstrated included approaching a barge next to a cargo vessel, performing automated docking, and maintaining the docking and solutions in the advent of an emergency.
The mobile harbor is, in essence, is a ‘moving port’ and the automated docking technology is imperative to commercialize the mobile harbor. In order for a large container ship to unload cargo, the mobile harbor needs to approach the container ship and dock onto the side of the ship.
The technology required to keep the two moving vessels docked, out at sea, in an efficient and safe manner, is daunting. The conventional method involved sailors tying the two vessels together with rope which made it time consuming and hard to react quickly in emergency situations.
The KAIST mobile harbor research team developed the docking technology with ‘Mirae Industrial Machine’ Maritime Corporation, and ‘Ocean Space’. The mobile harbor will allow two vessels to perform loading and unloading of cargo regardless of wind and current, using robotic arms, vacuum attachment pads, wench, and are a complex, integrated system.
KAIST is planning on having a demonstration that encompasses all the technology required for mobile harbor: from the docking technology to the stabilizing crane technology.
Advancements made by KAIST are expected to speed up the commercialization and the real life application of mobile harbor.

From Pencil Lead to Batteries: the Unlimited Transformation of Carbon
Those materials, like lead or diamond, made completely up of Carbon are being used in numerous ways as materials or parts. Especially with the discovery of carbon nanotubes, graphemes, and other carbon based materials in nanoscale, the carbon based materials are receiving a lot of interest in both fields of research and industry.
The carbon nanotubes and graphemes are considered as the ‘dream material’ and have a structure of a cross section of a bee hive. Such structure allows the material to have strength higher than that of a diamond and still be able to bend, be transparent and also conduct electricity. However the problem up till now was that these carbon structures appeared in layers and in bunches and were therefore hard to separate to individual layers or tubes.
Professor Kim Sang Wook’s research team developed the technology that can assemble the grapheme and carbon nanotubes in a three dimensional manner.
The team was able to assemble the grapheme ad carbon nanotubes in an entirely new three dimensional structure. In addition, the team was able to efficiently extract single layered grapheme from cheap pencil lead.
Professor Kim is scheduled to give a guest lecture in the “Materials Research Society” in San Francisco and the paper was published in ‘Advanced Functional Materials’ magazine as an ‘Invited Feature Article’.
