KAIST Develops Subminiature, Power-Efficient Air Pollution Sensing Probe
Professor Inkyu Park and his research team from the Department of Mechanical Engineering at KAIST have developed a subminiature, power-efficient air-pollution sensing probe that can be applied to mobile devices. Their research findings were published online in the January 30th issue of Scientific Reports. As air pollution has increased, people have taken greater interest in health care. The developed technology could allow people to measure independently the air pollution level of their surrounding environments. Previous instruments used to measure air pollution levels were bulky and consumed a lot of power. They also often produced inaccurate results when measuring air pollution in which different toxic gases were mixed. These problems could not be resolved with existing semiconductor manufacturing process. Using local temperature field control technology, Professor Park’s team succeeded in integrating multiple heterogeneous nanomaterials and fitting them onto a small, low-power electronic chip. This microheating sensor can heat microscale regions through local hydrothermal synthesis. Because it requires a miniscale amount of nanomaterials to manufacture, the sensor is most suitable for mobile devices. Professor Park said, “Our research will contribute to the development of convergence technology in such field as air pollution sensing probes, biosensors, electronic devices, and displays.” The team's research was supported by the Ministry of Education and the Ministry of Science, ICT and Future Planning, Republic of Korea.

The Number of KAIST Doctoral Graduates to Reach Over Ten Thousands
The ten-thousandth doctoral graduate received her degree in the commencement ceremony on February 13, 2015. KAIST has contributed to the development of science, technology, and industry in Korea by fostering talents in advanced science and engineering. Since its establishment forty-four years ago, more than ten-thousand KAIST alumni have received their doctorates. This year’s graduation ceremony took place on February 13, 2015, at the Sports Complex on campus, awarding the ten-thousandth doctoral degree. Dr. Sun-Mi Cho of the Department of Biological Sciences received the ten-thousandth doctoral degree. A graduate of Jeon-Nam Science High School, Dr. Cho also received her Bachelor of Science degree from KAIST. Dr. Cho wrote a dissertation entitled “GABA from reactive astrocytes impairs learning and memory in Alzheimer disease.” Her dissertation adviser was Professor Daesoo Kim of the Department of Biological Sciences. Dr. Cho, who will be a post-doctorate researcher at the Biological Sciences Department, said, “It was my childhood dream to receive a doctorate from KAIST. I cannot believe that I’m the ten-thousandth doctoral graduate, for which I’m very grateful.” She continued, “I hope to become a neuroscientist where I can be of help to the sick.” In 1978, KAIST only had two doctoral graduates, but since 1987 there have been more than one hundred graduates each year, two hundred since 1994, and four hundred since 2000. In 2015, 522 doctoral students graduated. One of the first doctoral graduates, Dong-Yol Yang (class of 1978 in the Mechanical Engineering Department), became a professor at the same department of KAIST. Professor Yang expressed his thoughts on the news, “There was a trend in Korea to go overseas for Ph.D. degrees in the early 1970s, but it changed when KAIST began to select candidates for Master’s degrees in 1973 and Doctoral degrees in 1975. Talented Korean students came to KAIST laboratories, and its graduates were known for their knowledge and skills. Now, we see that the talent is coming from overseas.” At the 2015 Commencement, KAIST conferred 522 Doctoral, 1,241 Master’s, and 915 Bachelor of Science (B.S.) degrees. Since its inception in 1971, KAIST has granted 10,403 doctor's, 26,402 master's, and 51,412 bachelor's degrees. In the picture below, Professor Dong-Yol Yang (left) seats next to Dr. Sun-Mi Cho (right), the recipient of 10,000th doctoral degree.

Professor Kwang-Hyun Cho Recognzied by "Scientist of the Month" Award
Professor Kwang-Hyun Cho of KAIST’s Department of Bio and Brain Engineering received the “Scientist of the Month” award in February 2015 from the Ministry of Science, ICT, and Future Planning of the Republic of Korea and the National Research Foundation of Korea. The award was in recognition of Professor Cho’s contribution to the advanced technique of controlling the death of cancer cells based on systems biology, a convergence research in information technology (IT) and biotechnology. Professor Cho has published around 140 articles in international journals, including 34 papers in renowned science journals such as Nature, Science, and Cell in the past three years. His work also includes systems biology textbooks and many entries in international academic encyclopaedia. His field, systems biology, is a new biological research paradigm that identifies and controls the fundamental principles of organisms on a systems level. A well-known tumour suppressor protein, p53, is known to suppress abnormal cell growth and promote apoptosis of can cells, and thus was a focus of research by many scientists, but its effect has been insignificant and brought many side effects. This was due to the complex function of p53 that controls various positive and negative feedbacks. Therefore, there was a limit to understanding the protein with the existing biological approach. However, Professor Cho found the kinetic change and function of p53 via a systems biology approach. By applying IT technology to complex biological networks, he also identified the response to stress and the survival and death signal transduction pathways of cardiomyocytes and developed new control methods for cancer cells. Professor Cho said, “This award served as a momentum to turn over a new leaf.” He added, “I hope convergence research such as my field will bring more innovative ideas on the boundaries of academia.”

Light Driven Drug-Enzyme Reaction Catalytic Platform Developed
Low Cost Dye Used, Hope for Future Development of High Value Medicinal Products to Treat Cardiovascular Disease and Gastric Ulcers A KAIST research team from the Departments of Materials Science and Engineering and of Chemical and Biomolecular Engineering, led respectively by Professors Chan Beum Park and Ki Jun Jeong, has developed a new reaction platform to induce drug-enzyme reaction using light. The research results were published in the journal Angewandte Chemie, International Edition, as the back cover on 12 January 2015. Applications of this technology may enable production of high value products such as medicine for cardiovascular disease and gastric ulcers, for example Omeprazole, using an inexpensive dye. Cytochrome P450 is an enzyme involved in oxidative response which has an important role in drug and hormone metabolism in organisms. It is known to be responsible for metabolism of 75% of drugs in humans and is considered a fundamental factor in new drug development. To activate cytochrome P450, the enzyme must receive an electron by reducing the enzyme. In addition, NADPH (a coenzyme) needs to be present. However, since NADPH is expensive, the use of cytochrome P450 was limited to the laboratory and has not yet been commercialized. The research team used photosensitizer eosin Y instead of NADPH to develop “Whole Cell Photo-Biocatalysis” in bacteria E. coli. By exposing inexpensive eosin Y to light, cytochrome P450 reaction was catalyzed to produce the expensive metabolic material. Professor Park said, “This research enabled industrial application of cytochrome P450 enzyme, which was previous limited.” He continued, “This technology will help greatly in producing high value medical products using cytochrome P450 enzyme.” The research was funded by the National Research Foundation of Korea and KAIST's High Risk High Return Project (HRHRP).
