At the first session entitled “Biotechnology Ecosystem,” he examined with other panelists the future of bioengineering in depth and discussed major policies and industry trends that will be necessary for the development of future biotechnologies. Professor Lee later attended the “Strategic Shifts in Healthcare” session as a moderator. Issues related to transforming the health industry such as the next-generation genomics, mobile health and telemedicine, and wearable devices and predictive analytics were addressed. On September 12, Professor Lee joined the “IdeasLab with KAIST” and gave a presentation on nanotechnology. There was a total of ten IdeasLab sessions held at the Summer Davos Forum, and KAIST was the only Korean university ever invited to host this session. In addition to Professor Lee’s presentation, three more presentations were made by KAIST professors on such topics as “Sustainable Energy and Materials” and “Next-generation Semiconductors.” Lastly, Professor Lee participated in the “Global Promising Technology” session with the World Economic Forum’s Global Agenda Council members. At this session, he explained the selection of the “World’s Top 10 Most Promising Technologies” and “Bio Sector’s Top 10 Technologies” and led discussions about the “2015 Top 10 Technologies” with the council members. The Davos Forum has been announcing the “World’s Top 10 Most Promising Technologies” since 2012, and Professor Lee has played a key role in the selection while working as the Chairman of Global Agenda Council. The selection results are presented at the Davos Forum every year and have attracted a lot of attention from around the world.

KAIST Researchers Fabricate Defect-free Graphene for Lithium-ion Batteries
Although graphene has been hailed as promising materials for lithium-ion batteries, making it for large-scale production has remained a challenging task for researchers. So far, high-quality graphene has been produced at the expense of large volume. It is possible to fabricate bulk quantities of graphene, but they will likely contain many defects. Recently, a KAIST research team, headed by Professors Jung-Ki Park and Hee-Tak Kim from the Department of Chemical and Biomolecular Engineering, developed a fabrication method to produce a large amount of defect-free graphene (df-G) while preserving the structural integrity of the graphene. This research result was published online in the July 11, 2014 issue of Nano Letters, entitled "Defect-free, Size-tunable Graphene for High-performance Lithium Ion Battery." Phys.org, a science, research and technology news website, published an article on this research.

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.

Regulatory T Cells Influence Liver Damage of Hepatitis A Patients
Liver damage becomes more severe with the decrease of regulatory T cells “This research will aid the development of hepatitis A targeted drug,” said a KAIST researcher. The KAIST Graduate School of Medical Science and Engineering’s Professor Eui-Cheol Shin and his research team have identified the mechanism, explaining how the regulatory T cells are responsible for the body’s immune system and how they have induced liver damage of hepatitis A patients. The research results were published online in the July 9th edition of ‘Gut,’ the world’s most prominent journal in the field of gastroenterology. Hepatitis A is an acute form of hepatitis caused by hepatitis A virus. The virus spreads through oral contact and enters the body via digestive organs. Regulatory T cells play an important role in maintaining the homeostasis of the body’s immune system by inhibiting the activation of other immune cells. In the case of chronic viral infections, regulatory T cells are known to contribute to the duration of the infection, weakening the immune response to virus infections. However, there has been no information on what roles the regulatory T cells perform in the case of acute viral infections. The research team used the fluorescence flow cytometry technique to determine the number and characteristics of a variety of immune cells, including regulatory T cells, in the blood of hepatitis A patients. Consequently, the researchers confirmed that the decrease in the regulatory T cells immune inhibitory ability was consistent with a significant reduction in the number of regulatory T cells in the blood of hepatitis A patients. Furthermore, it was identified that the more noticeable decrease of regulatory T cells led to the occurrence of a more severe liver injury. The analysis of hepatitis A patient’s blood proved that the cause of the decrease in the number and function of regulatory T cells was the increased expression of cell surface protein ‘Fas,’ which induces cell death. Professor Shin said, “This study is the first case which proposes the mechanism for clinical aspects in not only hepatitis A, but also acute virus infection.” He added on the future prospect of the research that: “In the future, we can prevent tissue damage by inhibiting cell death of regulatory T cells for severe acute viral infections that do not have an effective treatment for the virus itself.” [Picture] The picture shows the process of fluorescence flow cytometry technique to study regulatory T cell in the blood of hepatitis A patients.

The Journal of Clinical Investigation: Researchers Uncover the Secret Lymphatic Identity of the Schlemm's Canal
The Journal of Clinical Investigation (JCI), a peer-reviewed, top-tier medical journal published by the American Society for Clinical Investigation, carried a commentary entitled “Schlemm’s Canal: More Than Meets the Eye, Lymphatics in Disguise” in the July 25, 2014 issue. In the commentary, the authors compared a research paper (“Lymphatic regular PROX1 determines Schlemm’s canal integrity and identity”) by Professor Gou-Young Koh of the Graduate School of Medical Science and Engineering at KAIST with research work from the University of Helsinki (article entitled “The Schlemm’s canal is a VEGF-C/VEGFR-3 responsive lymphatic-like vessel”). The JCI released a press statement dated July 25, 2014 on its commentary. It mentioned that glaucoma, one of the leading causes of blindness worldwide, elevates eye pressure owing to poor drainage of aqueous humor. A specialized structure called “Schlemm’s canal” funnels aqueous humor from the eye back into circulation, which is critical to prevent pressure buildup in the eye. The article discussed the role of Schlemm’s canal in the context of lymphatic vascular characteristics by reviewing two research group’s papers back-to-back. For the full text of the press release, please visit the link below: Press Release from the Journal of Clinical Investigation, July 25, 2014 “Researchers uncover the secret lymphatic identity of the Schlemm’s canal” http://www.eurekalert.org/pub_releases/2014-07/joci-rut072414.php
