Prof. Chong Unveils New Human Movement Model
A KAIST research team headed by Prof. Song Chong of the School of Electrical Engineering and Computer Science has developed a new statistical model that simulates human mobility patterns, mimicking the way people move over the course of a day, a month or longer, university sources said on Tuesday (May 12).
The model, developed in collaboration with scientists at North Carolina State University, is the first to represent the regular movement patterns of humans using statistical data.
The model has a variety of potential uses, ranging from land use planning to public health studies on epidemic disease.
The researchers gave global positioning system (GPS) devices to approximately 100 volunteers at five locations in the U.S. and South Korea and tracked the participants" movements over time. By tracing the points where the study participants stopped, and their movement trajectories, researchers were able to determine patterns of mobility behavior.
The researchers were then able to emulate these fundamental statistical properties of human mobility into a model that could be used to represent the regular daily movement of humans. The model, called Self-similar Least Action Walk (SLAW), will have a wide array of practical applications.
The research, "SLAW: A Mobility Model for Human Walks," was presented on April 20 at the 28th IEEE Conference on Computer Communications in Rio de Janeiro, Brazil. The National Science Foundation of the U.S. funded the research.

KAIST Professor Unveils New Method of Manufacturing Complex Nano-wire
A KAIST research team led by Prof. Sang-Ouk Kim of the Department of Materials Science and Engineering has discovered a new nanowire manufacturing method, university sources said on Monday (May 11).
The KAIST researchers successfully demonstrated soft graphoepitaxy of block copolymer assembly as a facile, scalable nanolithography for highly ordered sub-30-nm scale features. Graphoepitaxy is a new technique that uses artificial surface relief structure to induce crystallographic orientation in thin films.
Various morphologies of hierarchical block copolymer assembly were achieved by means of disposable topographic confinement of photoresist pattern. Unlike usual graphoepitaxy, soft graphoepitaxy generates the functional nanostrutures of metal and semiconductor nanowire arrays without any trace of structure-directing topographic pattern.
The discovery was featured in the May 7 edition of Nano-Letters. Application has been made for the domestic patent of the new method.
The new method is expected to be advantageous for multi-layer overlay processing required for complex device architecture, the sources said.

KAIST Dedicates Geocentrifuge Experiment Center
KAIST dedicated the KOCED Geo-Centrifuge Experiment Center for researches in monitoring natural disasters such as earthquake and embankment collapse through miniature simulation tests on Wednesday (April 9) after a two-year construction work.
The experiment center is part of the Korea Construction Engineering Development Collaboratory Program (KOCED) which has been sponsored by the Ministry of Land, Transport and Maritime Affairs to build an infrastructure for construction engineering researches at a national level. The ministry plans to build a total of 5 similar centers nationwide by the end of the year.
On hand at the dedication ceremony were Jae-Choon Lee, President of the Korea Institute of Construction & Transportation Technology Evaluation and Planning, KAIST President Nam-Pyo Suh, and scores of experts and administration officials.
The construction of the five-story building on an area of about 3,328 square meters cost 8.4 billion won (US$6.3 million).
The center is expected to serve as a major laboratory in the field of geotechnical engineering. It is equipped with such state-of-the-art facilities as geocentrifuge, a useful tool for studying flow in unsaturated soil under well-controlled, repeatable conditions, a bidirectional shaking-table that can reproduce earthquake-like wave; and robots that can reproduce construction procedures by remote control.
Geocentrifuge experiment allows detecting ground and structure motions easily and rapidly by simulation tests. Thus, it is widely used for various geotechnical engineering researches such as evaluation of seismic safety, soft ground movement, slope stability analysis, etc. The causes of the embankment collapse in New Orleans by Hurricane Katrina in 2005 were also revealed by the geocentrifuge experiment.
The geocentrifuge research facility is available for use by outside researchers, so scientists from other universities, research institutes and corporations can perform research and test their scientific and engineering hypotheses.
The center is divided into two sections, experiment building and research building. The experiment building is composed of a geocentrifuge laboratory, model-making rooms, workshops, a geotechnical engineering laboratory and specimen storehouse, while the research building has a control room, a video conference room, an electronic library and research rooms.

KAIST Research Team Discovers Process for Rapid Growth of N-Doped CNT Arrays
A team of scientists led by Profs. Sang-Ouk Kim, Won-Jong Lee and Duck-Hyun Lee of the Department of Materials Science and Engineering has found a straightforward process for rapid growth of wall-number selected, nitrogen-doped carbon nanotube (CNT) arrays, university officials said on Monday (March 16).
KAIST researchers prepared highly uniform nanopatterned iron catalyst arrays by tilted deposition through block copolymer nanotemplates. This remarkably fast growth of highly uniform N-doped CNTs, whose material properties and chemical functionalizability are reinforced by N-doping, offers a new area of a large-scale nanofabrication, potentially useful for diverse nano-devices.
Carbon nanotubes (CNTs) are of broad technical interest in electronics, photonics, energy devices, and other applications. However, establishing a straightforward process for mass production of uniform CNTs with desired structure and properties has been a long-standing challenge.
In particular, it was strongly desired to precisely control the numbers of walls and diameter of CNTs, which are decisive parameters for the physical properties of CNTs. In this respect, the preparation of monodisperse catalyst array having a narrow size distribution is generally considered an effective pathway to produce well-defined CNTs, since the number of walls and diameter of the produced CNTs are closely related to the catalyst size.
The finding was featured in the March 13 edition of Nano Letters, a leading journal in the nano technology field.

Prof. Song Develops Nano-Structure to Enhance Power of Rechargeable Lithium-ion Battery
A team of scientists led by Prof. Hyun-Joon Song of the Department of Chemistry, KAIST, developed a nano-structure that could increase the power of rechargeable lithium-ion batteries, university sources said on Monday (Feb. 16).
The research team found that a nano-structured material using copper oxide (CuO) could produce lithium-ion batteries with some 50 percent more capacity than conventional products. The study was published in the online edition of peer-review journal Advanced Materials.
In rechargeable lithium-ion batteries, lithium ions move between the battery"s anode and cathode. The high-energy density of the batteries led to their common use in consumer electronics products, expecially portable devices. Their demand in automotive and aerospace applications is growing, and nano-structured, or nano-enabled batteries are emerging as the new generation of lithium-ion batteries for their edge in recharging time, capacity and battery life.
Graphite has been a popular material for cathodes in lithium-ion batteries. However, graphite cathodes are also blamed for lost capacity due to their consumption of lithium ions, which are linked to shorter battery life.
As such, scientists have been looking for materials that could replace graphite in cathodes, and silicon and metal oxide have been studied as possible alternatives.
