Technology that will allow household scale position tracking of smartphones indoors, where GPS signals do not reach, has been developed. It is anticipated that the newly developed technology will enable the tracking of persons indoors in an emergency situation or aid in the finding of a lost smartphone.
Professor Han Dong Soo (Department of Computer Sciences) and his research team has developed the technology that enables tracking a smartphone’s location indoors using wireless LAN signals accurate to 10 meters.
Because the technology utilizes wireless LAN signals and the address of smartphone users, the technology can be implemented for a low cost all over the world.
Conventionally the location of a lost smartphone can be found through a telecommunications company. However the location found using the base station is only accurate to 500m~700m and therefore reclaiming lost smartphones is nearly impossible.
In addition, there have been unfortunate events where the kidnapped victim called the police but was murdered due to the inaccuracy of smartphone location tracking.
The newly developed technology by Professor Han’s team remedies the inaccuracy of smartphone location tracking.
Professor Han’s team collected wireless LAN data recorded in the smartphones for a week to analyze the patterns to distinguish patterns between signals recorded in the workplace and in the household.
The stability and accuracy of the technology was verified over a period of five months in various locations across Korea with varying population densities.
The result was when the total amount of data collected passes 50% of the number of households, the technology show accuracy to 10 meters. The result showed that the new technology can track the location of the smartphone to 10 meters on a household scale. In addition it was possible to distinguish which floor the smartphone was located.
The technology is anticipated to improve smartphone positioning. However caution needs to be practiced as the technology requires the address of the user’s workplace and home.

Firefly inspired high efficiency LED technology developed
A firefly inspired, high efficiency self-illuminating LED has been developed.
Professor Jeong Gi Hoon (Department of Bio and Brain Engineering) mimicked the nanostructure of the external layer of the illumination organ of a firefly and succeeded in fabricating high illumination efficiency LED lenses.
Conventional lenses required expensive anti-reflection coating. The developed lenses utilize the bio-inspired nanostructure on the surface of the lenses themselves to reduce the reflectivity of the lenses thereby decreasing production costs.
The developed antireflection nanostructure is expected to be applied to various digital devices and lighting fixtures.
Antireflective structures have been applied in various fields in order to enhance light efficiency However these structures have been limited to flat surfaces and therefore was difficult to implement to curved surfaces like LED lenses.
Professor Jeong’s team solved this problem by using three dimensional micro molding processes.
The team fabricated the nanostructure by forming a single nanoparticle layer on the silicon oxide and performing dry etching. On this nanostructure PDMS was poured and manipulated to fabricate a lens structure similar to that of a firefly.
The fabricated lens showed similar efficiency as conventional antireflection coating.

Education 3.0: a change from teaching to learning
On October 16th, educationalists and Presidents from research-oriented universities around the world gathered in Seoul to attend the 2012 International Presidential Forum on Global Research Universities, where KAIST introduced its new smart learning model ‘Education 3.0’.
Smart learning ‘Education 3.0’ allows students to learn from lectures given by renowned scholars through the internet and encouraged student to professor discussion. This technology was created to deal with the ever-changing classroom dynamics due to the advancement of IT technology.‘Education 3.0’ differs from the traditional teaching-based lectures in that it offers a platform for self-directed learning. KAIST is working to spread ‘Education 3.0’ by providing specialized classrooms and running an online learning platform that complements it.
This spring, KAIST adopted ‘Education 3.0’ in 3 courses and received high praise from students (a rating of 4.4 out of 5.0). Hence, the number of courses was extended to 10 this fall.
Through this gathering, KAIST hopes to develop cooperative connections between foreign universities to share learning platforms and contents. On October 16th, KAIST signed a MOU with Denmark’s Danmarks Tekniske Universitet (DTU) to provide a cyber-dual degree program using ‘Education 3.0’. Hence, students studying Web science and Digital Media in either KAIST or DTU can receive degrees from both schools without physically visiting them.
President Suh said that “‘Education 3.0’ provides a new paradigm of learning which moves from the tradition cramming method of teaching to self-directed learning” and that this model will help the globalization of KAIST by initiating global cooperation with foreign universities.
Over 60 Universities from 27 different countries attended the forum, including ULCA and Caltech from the United States, DTU from Denmark, University of Southampton and University of York from England, University of Queensland from Australia, Nanyang Technological University from Singapore and Tokyo Institute of Technology from Japan. Members from Korean Universities such as Hanyang University, Handong Global University, Sogang University and Sookmyung Women"s University also attended.

Successful development and analysis of mesoporous quasicrystal structures
Professor Osamu Terasaki’s research team from the EEWS Graduate School at KAIST successfully synthesized mesoporous quasicrystalline silica and developed a new method of analyzing its growth. The theory proposed by the team laid the foundation for the scientific examination of quasicrystal phenomena during the formation of micelles particles, a type of soft matter. The paper was published in the July edition of Nature magazine.
Scientists have faced difficulty in systematically explaining the mesoporous quasicrystal structures that are found in solidified versions of soft matter systems. However, the theoretical foundation from this research is expected to help promote the research and development of new nano-structured materials.
Mesoporous quaicrystals are soft matters that have high symmetry and a larger characteristic length scale than the nanoscale, thereby making it possible to develop materials that have controllable optical properties. This technology can be applied to the sustainable storage, use, and reproduction of energy.
Professor Terasaki’s team succeeded in synthesizing mesoporous quasicrystalline silica and proved the formation of dodecagonal column-shaped crystals as well as dodecagonal, rotationally symmetric electron diffraction patterns near the crystals using Transmission Electron Microscopy.
Quasicrystals are an abbreviation of ‘quasiperiodic crystals’ and have what is called the ‘third solid’ property; they have a structural arrangement that is between arranged crystal structures, such as metals, and non-crystalline structures, such as glass. This crystalline structure was only recently found, and the 2011 Nobel Chemistry Award was given to research in this field.
When porous materials are synthesized into quasicrystals, the crystalline structures of the pores can be designed and controlled in any way, making it possible to create new materials for a wide range of fields.
Professor Terasaki said that ‘The discovery of highly symmetric quasicrystals can lead to the alteration of a material’s optical properties, allowing the development of photonic crystals in the visible spectra.’ He also explained that this control of a material’s optical energy absorption could be the core technology behind energy harvesting.
This research was jointly conducted by Professor Terasaki from the EEWS Graduate School at KAIST and Stockholm University in Sweden.

KAIST researchers verify and control the mechanical properties of graphene
KAIST researchers have successfully verified and controlled the mechanical properties of graphene, a next-generation material. Professor Park Jung Yong from the EEWS Graduate School and Professor Kim Yong Hyun from the Graduate School of Nanoscience and Technology have succeeded in fluorinating a single atomic-layered graphene sample and controlling its frictional and adhesive properties. This is the first time the frictional properties of graphene have been examined at the atomic level, and the technology is expected to be applied to nano-sized robots and microscopic joints.
Graphene is often dubbed “the dream material” because of its ability to conduct high amounts of electricity even when bent, making it the next-generation substitute for silicon semiconductors, paving the way for flexible display and wearable computer technologies. Graphene also has high potential applications in mechanical engineering because of its great material strength, but its mechanical properties remained elusive until now.
Professor Park’s research team successfully produced individual graphene samples with fluorine-deficiency at the atomic level by placing the samples in Fluoro-xenon (XeF2) gas and applying heat. The surface of the graphene was scanned using a micro probe and a high vacuum atomic microscope to measure its dynamic properties.
The research team found that the fluorinated graphene sample had 6 times more friction and 0.7 times more adhesiveness than the original graphene. Electrical measurements confirmed the fluorination process, and the analysis of the findings helped setup the theory of frictional changes in graphene.
Professor Park stated that “graphene can be used for the lubrication of joints in nano-sized devices” and that this research has numerous applications such as the coating of graphene-based microdynamic devices.
This research was published in the online June edition of Nano Letters and was supported by the Ministry of Science, Technology, and Education and the National Research Foundation as part of the World Class University (WCU) program.
