Busan, South Korea

Pusan National University is one of ten flagship Korean national universities and a leading university in South Korea. Located mainly in Busan , the university's English name is a translation of its former Korean name, "Gungnip Pusan Daehakgyo" , but has since dropped "national" from its Korean moniker. Continually ranked among one of top 500 world universities by ARWU World University Ranking and QS Top Universities Ranking, Pusan National University is one of only ten Korean universities ranked in both ARWU World University Ranking and QS Top Universities Ranking in 2010. In QS Top Universities Ranking 2010, Pusan National University is ranked in top five in social science and management, sixth in engineering and technology, sixth in life science and medicine, and ninth in arts and humanities among Korean universities. Pusan National University is one of only five Korean universities ranked in four subject areas in QS Top Universities Ranking 2010. Wikipedia.

A nanoenergetic material composite having a remote ignition characteristic by a high-power pulsed laser beam is prepared by adding various contents of multiwalled carbon nanotubes (MWCNTs) to a nanoenergetic composite material (nEM) to enable remote ignition by a high-power laser beam. The nanoenergetic material composite is a MWCNT/nEM composite powder prepared by adding multiwalled carbon nanotubes to the nanoenergetic material, which is a mixture of fuel material nanoparticles and metal oxidizer nanoparticles, wherein the multiwalled carbon nanotubes enhance a combustion rate of the MWCNT/nEM composite powder by delivering thermal energy upon remote optical ignition by the high-power pulsed laser beam.

The present invention relates to a motor driving apparatus and a home appliance including the same. A motor driving apparatus according to an embodiment of the present invention includes an inverter for converting a DC voltage of a DC-link capacitor into an AC voltage according to a switching operation and outputting the converted AC voltage to a motor; a DC-link resistor disposed between the DC-link capacitor and the inverter; and a controller for controlling the inverter based on a phase current sampled through the DC-link resistor, wherein the controller estimates a phase current based on the phase current sampled through the DC link resistor, in an interval in which phase current detection is not possible. Thereby, the phase current flowing through the motor may be accurately calculated using the DC link resistor.

Pusan National University's Distinguished Professor Axel Timmermann and Director of the IBS Center for Climate Physics (ICCP), has been awarded the 2017 Milutin Milankovic Medal for his fundamental and pioneering contributions to the understanding of climate dynamics. The Milutin Milankovic Medal is one of the highest honors bestowed by the European Geosciences Union (EGU) upon scientists working in the field of climate change and modeling. Since 1993 the EGU Division on Climate: Past, Present & Future has awarded this medal to 25 other outstanding scientists. Prof. Timmermann was selected for the medal as he "represents a rare example of a truly universal scientist who made significant contributions to understanding climate dynamics on very different spatial and temporal scales relevant both for past and future climate change" (Milutin Milankovic Medal 2017, http://www. ). Prof. Timmermann has made major contributions in a range of topics, including: El Niño-Southern Oscillation (ENSO) dynamics, abrupt climate change, dynamics of thermohaline circulation (ocean circulation driven by differences in seawater density), glacial dynamics, and human migration. Prof. Timmermann joined the Institute for Basic Science (IBS) in January 2017.

A hole transport layer composition is for a solar cell, a preparation method is thereof, and there is a solar cell comprising the same. More precisely, a hole transport layer composition for solar cell comprises the compound represented by formula 1. The hole transport layer composition can be used as a material for hole transport layer for solar cell which displays the improved power conversion efficiency than the conventional material. In addition, the hole transport layer composition demonstrates a high hole mobility, a proper energy level, a thermo-stability, and an excellent solubility, so that it can provide a similar or higher power conversion efficiency than the conventional spiro-OMeTAD. A solar cell comprising the hole transport layer composition displays a higher power conversion efficiency because the hole transport layer composition for solar cell includes a low-molecular material having a high charge carrier mobility instead of including a high-molecular material.

Omega-3 fatty acids, such as, DHA and EPA, have well established beneficial effects on human health, but their action mechanisms remain unknown. Recent pharmacological studies have suggested several molecular targets for the anti-inflammatory effects of omega-3 fatty acids, namely, nuclear receptor PPARγ and the G protein-coupled receptor GPR120. Furthermore, the conversions of omega-3 fatty acids to anti-inflammatory and pro-resolving resolvins and protectins and the identifications of putative target GPCRs, ChemR23, BLT1, ALX/FPR2, and GPR32, have drawn great attention. In addition, the pharmacology of omega-3 fatty acids is now under scrutiny. However, questions remain to be answered regarding the in vivo effects of omega-3 fatty acids at the molecular level. In this review, anti-inflammatory effects of omega-3 fatty acids are discussed from the viewpoint of molecular pharmacology, particularly with respect to the above-mentioned GPCRs. © 2012 Elsevier Ltd.

Signal amplification in conventional enzyme-based biosensors is not high enough to achieve the ultrasensitive detection of biomolecules. In recent years, signal amplification has been improved by combining enzymatic reactions with redox cycling or employing multienzyme labels per detection probe. Electrochemical-chemical redox cycling and electrochemical-chemical-chemical redox cycling allow ultrasensitive detection simply by including one or two more chemicals in a solution without the use of an additional enzyme and/or electrode. Multiple horseradish peroxidase labels on magnetic bead carriers provide high signal enhancement along with a multiplex detection possibility. In both cases, the detection procedures are the same as those in conventional enzyme-based electrochemical sensors. © 2012 Elsevier Ltd.
