  • 10 m3/min (CMM) multi-pollutants abatement system was successfully developed by effectively integrating ozone oxidation, wet scrubbing, and wet electrostatic precipitation for the simultaneous removal of particulate matters (PMs) and NOx in a semiconductor fabrication process. The sophisticated control and optimization of operating parameters were conducted to maximize the destruction and removal efficiency of NOx. In particular, the stability test of a wet electrostatic precipitator was carried out in parallel for 30 days to validate the reliability of core parts including a power supply. An O3/NO ratio, which is the most important operating parameter, was optimized to be about 1.5 and the optimization of wet scrubbing with a reducing agent made it possible to analyze the contribution of neutralization reaction.

  • The purpose of this study is to analyze the relationship between parental perfectionism, academic stress, and life satisfaction among high school students. For this purpose, 290 high school students from the P region were surveyed. We performed a t-test to see if there were significant differences in students' life satisfaction and perceived academic stress between the low parental perfectionism group and the high parental perfectionism group. The results of the study are as follows. First, the low parental perfectionism group reported a significantly higher level of life satisfaction than high parental perfectionism group. Second, the relationship between perceived parental perfectionism and students' academic stress was significant, which shows that the high parental perfectionism group perceived a higher level of academic stress than the low parental perfectionism group. The results indicate that parents' perfectionistic tendencies can lead to higher levels of academic stress of their children, which also can reduce their life satisfaction.
