In this study, effect of temperature and time on melt-out of 25wt% Al-alloyed ductile iron has been investigated. The oxidation tests were carried out in a tube furnace at $800^\circC$, $930^\circC$, and $1000^\circC$ for lh, 5h, 10h, 50h. The microstructure, microhardness, and $Al_2O_3$ layer of oxidation-treated 25wt% Al-alloyed ductile iron samples (10 x 10 x 10 mm) were investigated. Phase identification was performed by X-ray diffraction(XRD) and EDS. The oxidation-treated 25wt% Al-alloyed ductile iron samples at $930^\circC$ for lh, 5h, 10h and KS GCD 500 were used for melt-out test in an Al alloy melt. The melt-out test results showed that oxidation tested sample at $930^\circC$ for 5h which on the whole forms $2-3\mum$ $Al_2O_3$ layer showed lowest melt-out depth. It was observed showed that appropriate Al203 layer can affect melt-out behaviors.

Objectives: This study examines the effect of Banhabaekchulcheonma-tang on Benign Paroxysmal Positional Vertigo (BPPV) through a systematic review of randomized controlled trials (RCTs) in the Chinese National Knowledge Infrastructure Database (CNKI). Methods: RCTs were included that tested the effect of Banhabaekchulcheonma-tang on BPPV. A study of the literature in the CNKI was performed for papers published from January 1, 2011 to June 30, 2021. Results: A total of eight RCTs met the inclusion criteria. All studies identified the effect of Banhabaekchulcheonma-tang in the treatment of BPPV. The effectiveness of treatment was higher in the intervention group than in the control group, as shown through evaluation indicators, including the total effective rate, dizziness handicap inventory (DHI), and blood lipids. Conclusion: Treatment with Banhabaakchulcheonma-tang was found to be effective in treating BPPV. However, due to the low quality of available studies, the significance of this conclusion is somewhat limited. Further clinical studies are needed on the development of diagnosis and treatment methods for BPPV based on Korean medicine.
