KAIST Conducts Safety Awareness Campaign for Research and Experiment
KAIST had an opening ceremony to hold its first “Safety Awareness Campaign for Research and Experiment” on 13th May. Over 100 people attended the ceremony, including President Steve Kang, Provost Gyu-Ho Park, and the Dean of the Administration Office Jae-Nam Lee, as well as the Chief of the Department of Research Environment Safety from the Ministry of Science, ICT and Future Planning, Republic of Korea.
On the day of the event, Year 2014 was proclaimed as the first year of accident-free KAIST research and laboratory facilities.
A certificate of merit was awarded to promote safe and comfortable research environments. The Department of Civil and Environmental Engineering, KAIST, was selected as the department with the best lab safety management and the Department of Mechanical Engineering as the second.
Along with the merit award ceremony, the results of the “7th Research and Laboratory Safety Campaign Contest” were announced: “Lady First When Dating, Safety First When Experimenting!” written by Jong-Su Bae from the Department of Mechanical Engineering was selected as the best slogan, and Hyeon-Chae Noh from the Department of Civil and Environmental Engineering received the award for best poster.
President Steve Kang said, “KAIST is constantly striving to establish a comprehensive safety management system and to promote a safe research and laboratory environment,” and “To ensure the safety of KAIST and its members, we will be as supportive as possible.”
Below is the winner of the poster from the 7th Research and Laboratory Safety Campaign Contest.
What Would You Rather Wear? Gloves or Bandages?
Gloves worn in laboratories are protection from hazardous materials that students and researchers may come in contact with. The poster emphasizes the importance of wearing protective gloves when conducting research or experiment.

Leon Chua, the founder of the circuit theory called "memristor," gave a talk at KAIST
Dr. Leon Ong Chua is a circuit theorist and professor in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley. He visited KAIST on April 16, 2014 and gave a talk entitled “Memristor: New Device with Intelligence.”
Dr. Chua contributed to the development of nonlinear circuit theory and cellular neural networks (CNN). He was also the first to conceive of memristor which combines the characteristics of memory and resistor. Memristor is a type of resistor, remembering the direction and charge of electrical current that has previously flowed through the resistor. In other words, memristor can retain memory without power. Today, memristor is regarded as the fourth fundamental circuit element, together with capacitors, inductors, and resistors.
In 2008, researchers at Hewlett-Packard (HP) Labs developed the first working model of memristor, which was reported in Nature (May 1st , 2008).
In addition, Dr. Chua is an IEEE fellow and has received numerous awards including the IEEE Kirchhoff Award, the IEEE Neural Network Pioneer Award, the IEEE Third Millennium Medal, and the Top 15 Most Cited Author in Engineering Award.

Hidden Mechanism for the Suppression of Colon Cancer Identified
Published in Cell Reports : cells at the risk of causing colorectal cancer due to genetic mutation are discharged outside the colon tissue
Korean researchers have successfully identified the cancer inhibitory mechanism of the colon tissue. The discovery of the inherent defense mechanism of the colon tissues is expected to provide understanding of the cause of colorectal cancer.
The research was led by Kwang-Hyun Cho, a professor of Bio and Brain Engineering at KAIST (corresponding author) and participated by Dr. Jehun Song (the first author), as well as Dr. Owen Sansom, David Huels, and Rachel Ridgway from the Beatson Institute for Cancer Research in the UK and Dr. Walter Kolch from Conway Institute in Ireland.
The research was funded by the Ministry of Science, ICT and Future Planning and the National Research Foundation of Korea, and its results were published in the 28th March online edition of Cell Reports under the title of “The APC network regulates the removal of mutated cells from colonic crypts.”
The organism can repair damaged tissues by itself, but genetic mutations, which may cause cancer, can occur in the process of cell division s for the repair. The rapid cell division s and toxic substances from the digestive process cause a problem especially in colon crypt that has a high probability for genetic mutation.
The research team was able to find out that the colon tissues prevent cancer by rapidly discharging carcinogenic cells with genetic mutations from the colon crypt durin ga frequent tissue repair process.
This defense mechanism, which inhibits abnormal cell division s by reducing the time mutated cells reside in the crypt, is inherent in the colon.
Extensive mathematical simulation results show that the mutated cells with enhanced Wnt signaling acquire increased adhesion in comparison to the normal cells, which therefore move rapidly toward the upper part of the crypt and are discharged more easily.
If beta-catenine, the key factor in Wnt signal transduction pathway, is not degraded due to genetic mutation, the accumulated beta-catenine activates cell proliferation and increases cell adhesion. The special environment of crypt tissue and the tendency of the cells with similar adhesion to aggregate will therefore discharge the mutated cell, hence maintaining the tissue homeostasis.
In vivo experiment with a mouse model confirms the simulation results that, in the case of abnormal crypt, the cells with high proliferation in fact move slower.
Professor Cho said, “This research has identified that multicellular organism is exquisitely designed to maintain the tissue homeostasis despite abnormal cell mutation. This also proves the systems biology research, which is a convergence of information technology and bio-technology , can discover hidden mechanisms behind complex biological phenomena.”
Crypt: Epithelium, consisting of approximately 2,000 cells, forms a colon surface in the shape of a cave.
Wnt Signaling: A signal transduction pathway involved in the proliferation and differentiation of cells that are particularly important for the embryonic development and management of adult tissue homeostasis.

Professor Sang-Ouk Kim Publishes Review Article in the Journal of "Nature Materials"
Nature Materials, a
peer-reviewed scientific journal published by Nature Publishing Group, covers a
range of topics within materials science from materials engineering and
structural materials. The
journal invited Professor Sang-Ouk Kim of Materials Science and Engineering at
KAIST to contribute to the April issue of 2014. Professor Kim,
together with his doctoral student, Ju-Young Kim, wrote a review article in the
“News and Views” section of the journal, which was entitled “Liquid Crystals:
Electric Fields Line Up Graphene Oxide.” The
News and Views is a peer-reviewed section where an academic authority in a particular
field reviews and evaluates papers published in the journal. In
the article, Professor Kim reviewed a paper written by Jang-Kun Song et al. and
highlighted important research outcomes such as the efficient electric field switching
of graphene oxide (GO) liquid-crystals in low-concentration dispersions and the
demonstration of a prototype of a GO liquid-crystal display. This technology
could lead the development of a flexible display. Professor
Kim is an eminent scholar who has reported for the first time in the world on
the solvent-based graphene oxide liquid crystals formation in 2011. For the article, please go to: http://www.kaist.ac.kr/_prog/download.php?filename=Nature_Materials_Professor_Sang-Ouk_Kim_Apr_2014.pdf

Professor Huen Lee to Receive Lifetime Achievement Award from the International Conference on Gas Hydrates
Professor Huen Lee of the Chemical and
Biomolecular Engineering Department at KAIST will receive a lifetime
achievement award at the 8th International Conference on Gas
Hydrates (ICGH) to be held from July 28, 2014 to August 2, 2014 in Beijing,
China.
Among his other scholarly and research accomplishments, Professor Lee achieved the development of natural gas by injecting
carbon dioxide and nitrogen into the layers of gas hydrates. With this
technology, ConocoPhilips, an American multinational energy corporation,
successfully extracted natural gas from the gas hydrates in the North Slope of
Alaska in the US in April 2012.
Meeting every three years in a different
country around the world, ICGH is a leading gathering of scientists and
engineers in gas hydrates. The 8th conference will be held under the
theme of “Opportunity and Challenge-Development and Utilization of Gas
Hydrates.”
