In 2008, POSTECH Alumnus Dr. Donghun Lee made an unexpected discovery during his study of single dopants in Gallium Arsenide (GaAs) semiconductors, which are used for satellites or military products. A dopant is a substance that produces a desired electrical characteristic for semiconductors, and Dr. Lee had been studying a defect semiconductor where one of the lattice points had a dopant atom missing. He experimented by pushing the atom to the next lattice point, and surprisingly, the atoms automatically rearranged themselves to fill the vacant places as in a puzzle game. Now the defect produ..
Professor Kwang Soo Kim has come forth with a revolutionary and unprecedented method for DNA sequencing that can potentially decode 3 billion pairs of human genes in an hour. The field of DNA sequencing caught the world’s attention when the Human Genome Project was successfully completed in 2003, and many developed nations have since been competing to develop ways to increase the speed of genetic sequencing and analysis. This research is closely related with treating intractable or rare diseases and therefore will have important implications for life science. Professor Kim, well-known fo..
A new drug delivery system, whose nanopores open or close depending on electrical stimulus, has been established by Professor Jin Kon Kim, Director of National Creativity Research Initiative Program for Block Copolymer Self-Assembly. The device can also be manipulated by a remote controller while being planted inside a human body. Published on Nano Letters (11(3), 1284-1288 (2011)), an authoritative journal on nanoscience, the article, ‘Electrically Actuatable Smart Nanoporous Membrane for Pulsatile Drug Release,’ discusses how the new device can freely control the release of drugs..

It has been reported that universities in Seoul conduct between 20 and 40 percent of their lectures in English. A desire to keep in step with globalization and bump up Korean universities’ place in world rankings have been cited as the rationale behind the push for more English lectures. But the move toward t..

This is much earlier than their Western European OECD counterparts, who usually retire at 65 or older, and for whom even early retirement is usually 60 or older.The survey results raised an issue that has puzzled me for a long time: Why do so many Korean workers retire in their mid-50s? This is tru..

I asked what would happen if Caltech or MIT set up a Korean branch and offered courses in English only, except for language-specific courses? I p..
A new cooperative partnership has been established with the Hong Kong University of Science and Technology (HKUST).President Sunggi Baik visited HKUST on April 7, 2011, to sign agreements for university-wide cooperation and a joint Ph.D. degree program with the HKUST School of Engineering.In accordance to the student exchange clauses of the cooperation agreement, POSTECH undergraduate students have HKUST added to their choice of study abroad institutions starting Spring Semester 2012.Candidates of the POSTECH-HKUST joint Ph.D. program will have co-advisors at both POSTECH and HKUST, and spend ..
Arsenic is a poisonous metalloid that pollutes the land and drinking water in many countries in Southeast Asia, mainly in Bangladesh or Cambodia, and neither is a developed country free from this problem: it still remains in certain mining areas, timber or paper mills and industrial areas. The ingestion of crops contaminated by arsenic can cause cancer, digestive disorders and skin diseases, because it becomes accumulated in the human body instead of being digested or excreted. Professor Youngsook Lee, Department of Life Science, and her research team including Dr. Won-Yong Song, Postdoctoral ..
