As the eventful year of 2008 comes to a close and the New Year of 2009 begins, I wish all of you a New Year full of happiness and love.2009 is the Year of the Ox. There is an old saying that goes, “Ox pace takes you a thousand miles,” which means slow and steady steps take you much farther. This year’s start is cloudier and gloomier than ever. The recent global economic crisis has been even more brutal than the foreign exchange crisis we experienced a decade ago. At a time of such hardship, we should learn from the wisdom of the ox, not panicking or getting nervous, but being..
Honorable founding Chairman Tae-Joon Park, fellow Postechians, guests, ladies and gentlemen!We are gathered here today to commemorate the significant occasion of POSTECH’s 20th Anniversary.I would like to extend my deepest respects to the founding Chairman Tae-Joon Park for his dedication and resolution to establish a world-class research-oriented university despite overwhelming criticism and opposition 20 years ago and to POSTECH Foundation and POSCO for their absolute confidence and wholehearted support. Also, warm welcome is due to the many dedicated people who have contributed to mak..
A multi-platform supporting mobile applications software development environment technology has been developed. More than 30% of current development effort is expected to be saved through the new environment. Professor Kyo-Chul Kang (Department of Computer Science and Engineering) and his research team have joined efforts with Electronics and Telecommunications Research Institute (ETRI) in the Mobile Platform based Application Development (MoPAD) project which launched in March 2007 with the support of Institute for Information Technology Advancement. The first report of the research outcomes ..
Direct printing of functional electronic materials may provide a promising route to low-cost fabrication of integrated circuits. From this point of view, ink-jet printing has received special attention as a direct patterning technique for the cost-effective fabrication of organic electronic devices such as organic thin-film transistors (OTFTs) (Figure 1) and organic photovoltaic cells. Professor Kilwon Cho and Ms. Jung Ah Lim of the Department of Chemical Engineering have succeeded in fabricating high-performance OTFTs by inkjet printing of organic semiconductor. This result entitled “Se..
The way to prevent intra-operative awareness has been paved by joint efforts of medical science and physics. Intra-operative awareness, familiarized through some thriller movies, is a unique physiological phenomenon which causes the patient under general anesthesia to recover consciousness during surgery. The patient experiencing intra-operative awareness may feel the pain or pressure of surgery, hear conversations, or feel as if he cannot breathe, but may be unable to communicate any distress because he has been given a paralytic or muscle relaxant.Professor Seunghwan Kim (Department of Physi..
30-nano class Gallium Arsenide (GaAs) nano-transistor: comparative advantages in its performanceEasy manufacturing process: less than half the cost of commercializationIt is possible to receive and enjoy various multimedia contents such as music, movies, and other data, at speeds of several tens of Mbps using high-speed internet widely available in households. Studies on the improvement of communication speeds have been continuously conducted over the recent years.Professor Yoon-Ha Jeong and research team have successfully succeeded in developing 35-nano GaAs nano-transistors (metamorphic HEMT..
Revolutionary plastic memory devices developedRecent increases in demand for mobile devices have stimulated the development of nonvolatile memory devices with high performance. These nonvolatile memory devices are unpowered computer memory devices such as USB flash drives. However, with recent developments will soon see foldable electronic newspapers, books, magazines, and even wearable computers. Professor Moonhor Ree (Department of Chemistry) and Professor Ohyun Kim (Department of Electronic and Electrical Engineering) research team, in their paper entitled, “Novel Digital Nonvolatile ..
POSTECH celebrated its 20th Anniversary on December 3rd, 2006.On December 3rd, 1986 established as Korea’s first research-oriented science and technology university, POSTECH began its journey to become one of the world’s leading research-oriented universities.After a short history of only 12 years, POSTECH topped the list of Asia’s leading science and technology universities by Hong Kong based Asiaweek in 1998 and the Times Higher Education Supplement ranked POSTECH 25th (3rd in Asia) in citations per faculty.The main driving force of POSTECH’s rise to the top was the f..
It is well known that plants can fix carbon dioxide (CO2) into sugar. In plant cells, the chloroplast is responsible for fixing carbon dioxide into sugar. Thus chloroplasts as the factory for sugar production play essential roles not only for plants themselves but also for most of living organisms on Earth. However, chloroplasts are not just carbon dioxide fixing factory but also responsible for producing a large number of chemical compounds that are essential for plant growth and development. Interestingly, chloroplasts in plant cells are thought to be originated from ancestral cyanobacterium..
Lord Rayleigh wrote about the two-dimensional whispering gallery mode (WGM) in 1910 after a visit to the dome of St. Paul’s cathedral in London. The whispering cave mode (WCM) is a threedimensional (3D) effect?a toroid with circular helix symmetry?which recent studies have shown can be used to create photonic-quantum-ring (PQR) lasers that emit in the blue-violet part of the spectrum. A research team at Pohang University of Science and Technology (POSTECH, Pohang, Korea) first created 3D WCM lasers that emit in the infrared and red part of the spectrum. To achieve this, professor O&rsquo..
