3D Printer Developed by KAIST Undergraduate Students
More than 100 Pre-orders Prior to Product Launch Made
KAIST undergraduate students received more than 100 pre-orders before the launch for 3D printers they developed and became a hot topic of interest.
KAIST Research Institute for Social Technology and Innovations (Head Hong-Kyu Lee) had a launch party at Daejeon Riviera Hotel on 17 November 2014 for “Commercial Delta 3D Printer” developed by KAIST undergraduate students inviting around 50 businesses, buyers and representatives of 3D Printing Industry Association.
“3D Printer” uses blueprints of products such as toys, mug cups and chairs to make 3D objects and is thought to be revolutionary technology in manufacturing industry. The interest has grown as recent printers could print even fruits and cosmetics.
The printing structure of 3D printer can be divided roughly into horizontal Mendel method and Delta method. KAIST students focused on the Delta method to give a differentiated product from 90% of commercial products that use Mendel method.
First, the students focused on lowering the cost of unit price by using self-developed components. The carriage (transport machine) of the product is replaced by self-developed components instead of bearing to reduce the noise and the linking method was changed to beads from loop guide to increase the completeness of the printed product. Also, an auto-levelling is loaded to ensure the nozzle and the bed is parallel and hence increasing convenience for the users. Further, the printer, designed by a product designer in Germany, is linked to a smartphone application for blueprints.
A student in the development team, Seokhyeon Seo (Department of Computer Science, 3rd Year Undergraduate) said, “The biggest merits of the product are lowering the price to a 1/3 by using self-developed components and reducing the noise.” He continued, “By using a smartphone application, anyone can easily design the product. So it is applicable to use for education or at home”
In the exhibit, “3D Printing Korea 2014,” in Coex, Seoul the printer had a preview demonstration, and received more than 100 pre-orders from educational and business training institutions. Further, buyers from Canada and the US requested opening agencies in their countries.
KAIST Research Institute for Social Technology and Innovations Head Hong-Kyu Lee said, “3D printing is an innovative technology that could bring the 3rd industrial revolution.” He continued, “It is still early days but the demand will increase exponentially.”
This project was a research project of KAIST Research Institute for Social Technology and Innovations led by a development team consisting of 4 undergraduate students of KAIST, one student from University of Oxford and one German product designer.

KAIST and Samsung Heavy Industries Celebrate 20 Years of Cooperation
KAIST and Samsung Heavy Industries (SHI) celebrated the twentieth anniversary of their university-industry cooperation in shipbuilding and ocean technology research. Established in 1995, the cooperation has remained steadfast for two decades, even times when Korea suffered gravely from its financial crisis in late 1990s.
A ceremony to commemorate the cooperation took place at the Mechanical Engineering Building on October 17, 2014. About thirty distinguished guests including the Head of the Department of Mechanical Engineering, Professor Choong-Sik Bae, and the chief engineer of SHI Marine Research Institute, Dr. Jong-Soo Seo, participated in the ceremony.
The cooperation programs included appointing advisory professors for technological support, implementing business-based academic courses, offering university-industry wide open lectures, opening regular courses for auditing, and finding possible joint researches. Through this cooperation, Samsung has secured technologies needed for industry, and KAIST has produced students who have real-world experience in industrial fields.
Twenty years of cooperation has produced shining results by running various programs such as technological advice, special lectures, small-scale research projects, consignment research projects, and courses for research and design personnel.
For example, what started as a small-scale research project with USD 4,800 in funding, the LNG (Liquefied Natural Gas) related research has grown into a large-scale research project with a total of USD 2.85 million in funding. As a result, they developed a secondary barrier for LNG carriers which was recognized by Lloyd‘s Register. Their research eventually lowered ship manufacturing costs tremendously.
In 2003, the cooperation project received the presidential citation from the University-Industry Cooperation Competition organized by the Federation of Korean Industries.
KAIST and SHI planned to increase their cooperation to make it Korea’s leading university-industry cooperation program.
Professor Bae said, “Our programs to focus on solving industrial problems have turned out quite successful.” He emphasized that “for this reason, the cooperation even continued during the Asian financial crisis in 1997.”
He added, “By expanding the current cooperation, we aim to make it an exemplary program that contributes to Korea’s shipbuilding and ocean plant industries.”

KAIST Registers an Internationally Recognized Standard Patent
A video compression technology, jointly developed by Professor Mun-Chul Kim of the Department of Electrical Engineering at KAIST, the Electronics and Telecommunications Research Institute (ETRI), and the Korean Broadcasting System (KBS), is registered internationally as the standard patent in the next-generation High Efficiency Video Coding (HEVC).
HEVC (H.265) is an international technology standard that compresses large image data for Ultra High Definition (UHD) televisions and smartphones. It has the twice the compression efficiency as that of H.264/AVC which is most commonly used for processing full HD sources. This means that it is able to compress a video file to half the size while maintaining the same image quality.
Although the related market is at a nascent stage, HEVC technology has already been applied to the latest version of televisions and smartphones. Experts predict that the market will grow to USD 200 billion by 2016, and KAIST is expected to receive a royalty payment of USD 9.3 million from this patent.
The International Organization for Standardization (ISO/IEC) established the HEVC standard in January 2013. Also, an international patent pool licensing corporation, MPEG LA announced the HEVC standard patent pool on September 29, 2014.
Professor Joongmyeon Bae, Dean of the Office of University-Industry Cooperation (OUIC) of KAIST, said, “This is an unprecedented case for Korea whereby a core technology developed by a university became an international standard, which has a vast impact on the market.”
President of KAIST, Steve Kang commented, “With its advanced technology, KAIST joined the HEVC standard patent pool as one of the 23 founding members along with Apple, Siemens, and NEC. This is a remarkable achievement.”

Extracting Light from Graphite: Core Technology of Graphene Quantum Dots Display Developed
Professor Seokwoo Jeon of the Department of Materials Science and Engineering, Professor Yong-Hoon Cho of the Department of Physics, and Professor Seunghyup Yoo of the Department of Electrical Engineering announced that they were able to develop topnotch graphene quantum dots from graphite.
Using the method of synthesizing graphite intercalation compound from graphite with salt and water, the research team developed graphene quantum dots in an ecofriendly way.
The quantum dots have a diameter of 5 nanometers with their sizes equal and yield high quantum efficiency. Unlike conventional quantum dots, they are not comprised of toxic materials such as lead or cadmium. As the quantum dots can be developed from materials which can be easily found in the nature, researchers look forward to putting these into mass production at low cost.
The research team also discovered a luminescence mechanism of graphene quantum dots and confirmed the possibility of commercial use by developing quantum dot light-emitting diodes with brightness of 1,000 cd/m2, which is greater than that of cellphone displays.
Professor Seokwoo Jeon said, “Although quantum dot LEDs have a lower luminous efficiency than existing ones, their luminescent property can be further improved” and emphasized that “using quantum dot displays will allow us to develop not only paper-thin displays but also flexible ones.”
Sponsored by Graphene Research Center in KAIST Institute for NanoCentury, the research finding was published online in the April 20th issue of Advanced Optical Materials.

The MIT Skoltech Initiative Report identifies KAIST as one of the core group of emerging leaders for academic entrepreneurship and innovation
The Massachusetts Institute of Technology (MIT) Skoltech Initiative was established in 2011 to support MIT’s multi-year collaboration in building the Skolkovo Institute of Science and Technology (Skoltech), a private graduate research university in Skolkovo, Russia.
Recently, the office of the MIT Skoltech Initiative has published a benchmark report conducted from 2012 to 2014 by Dr. Ruth Graham, an internationally recognized leading consultant for engineering education and research as well as academic technology-driven entrepreneurship, under the guidance of MIT professors and the Center for Entrepreneurship and Innovation at the MIT Skoltech Initiative.
The report identified more than 200 institutions as the world’s most highly-regarded entrepreneurial universities and characterized the approach taken by them to build university-based ecosystems for entrepreneurship and innovation (E&I).
Among the top-ranked institutions, the report mentioned an emerging group of leaders (EGLs) that are “located within more challenging environments but establishing strong entrepreneurship and innovation profiles and reputations.” The report named, in particular, five universities, KAIST (Korea), Technion (Israel), Aalto University (Finland), the University of Michigan (US), and the University of Auckland (NZ), as the core group of the EGLs.
This benchmarking study was written to highlight key strategies and features associated with well-regarded university E&I transformations within more challenging environments and to address barriers and limits faced by the EGLs, thereby providing a good model to other universities wishing to make similar changes.
Through an in-depth case study of a small group of emerging universities, the report concluded that three major components play a critical role in the development of institutional E&I capacity and the growth of ecosystems for E&I:
Component 1: Inclusive grassroots community of E&I engagement across university populations and regional community;
Component 2: Strength in industry-funded research and licensing of university-owned technology; and
Component 3: University E&I agenda reflected in its policies, mission, budget allocations, incentives and curriculum

Discovery of New Therapeutic Targets for Alzheimer's Disease
A Korean research team headed by Professor Dae-Soo Kim of Biological Sciences at KAIST and Dr. Chang-Jun Lee from the Korea Institute of Science and Technology (KIST) successfully identified that reactive astrocytes, commonly observed in brains affected by Alzheimer’s disease, produce abnormal amounts of inhibitory neurotransmitter gamma-Aminobutyric acid (GABA) in reaction to the enzyme Monoamine oxidase B (Mao-B) and release GABA through the Bestrophin-1 channel to suppress the normal signal transmission of brain nerve cells.
By suppressing the GABA production or release from reactive astrocytes, the research team was able to restore the model mice's memory and learning impairment caused by Alzheimer’s disease. This discovery will allow the development of new drugs to treat Alzheimer’s and other related diseases.
The research result was published in the June 29, 2014 edition of Nature Medicine (Title: GABA from Reactive Astrocytes Impairs Memory in Mouse Models of Alzheimer’s Disease).

First Instance of Negative Effects from Terahertz-Range Electromagnetic Waves
Professor Philhan Kim
Electromagnetic waves (EM-wave) in the terahertz range were widely regarded as the “dream wavelength” due to its perceived neutrality. Its application was also wider than X-rays. However, KAIST scientists have discovered negative effects from terahertz EM-waves.
Professor Philhan Kim of KAIST’s Graduate School of Nanoscience and Technology and Dr. Young-wook Jeong of the Korea Atomic Energy Research Institute (KAERI) observed inflammation of animal skin tissue when exposed to terahertz EM-waves.
The results were published in the online edition of Optics Express (May 19, 20104).
Terahertz waves range from 0.1 to 10 terahertz and have a longer wavelength than visible or infrared light. Commonly used to see through objects like the X-ray, it was believed that the low energy of terahertz waves did not inflict any harm on the human body.
Despite being applied for security checks, next-generation wireless communications, and medical imaging technology, little research has been conducted in proving its safety and impact. Conventional research failed to predict the exact impact of terahertz waves on organic tissues as only artificially cultured cells were used.
The research team at KAERI developed a high power terahertz EM-wave generator that can be used on live organisms. A high power generator was necessary in applications such as biosensors and required up to 10 times greater power than currently used telecommunications EM-wave. Simultaneously, a KAIST research team developed a high speed, high resolution video-laser microscope that can distinguish cells within the organism.
The experiment exposed 30 minutes of terahertz EM-wave on genetically modified mice and found six times the normal number of inflammation cells in the skin tissue after six hours. It was the first instance where negative side effects of terahertz EM-wave were observed.
Professor Kim commented that “the research has set a standard for how we can use the terahertz EM-wave safely” and that “we will use this research to analyze and understand the effects of other EM-waves on organisms.”
