The standard Japanese conjunctions for providing a reason, から and ので, may become よって and さかい in Kansai-ben (with the choice depending on the area or personal background such as age).
よって is mostly used by older people while さかい is used by a wider range of ages. In addition, younger people may opt to just use から and ので with a Kansai-ben intonation.
It should also be noted that さかい may become さかいに, さかいで, or さけ, with the difference depending on the region or speaker preference.
