Abstract
DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference are measured as a function of temperature. Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample.
Glass transitions may occur as the temperature of an amorphous solid is increased. Th

The interviewee, manager of transportation information Sung-Hoon Shin, explained that the existence of terminals reduce the inconvenience of waiting for the bus outside in the cold or heat. By knowing when the bus will arrive, citizens can make better decisions. On the right is a picture taken inside the Gwanghwamoon Station (Line 5), which shows the location of nearby buses.
