■  Mask business

ㆍ This division judged that masks would become commonplace in the future because of the severity of fine dust 

     at the end of 2019 and accordingly secured a production line through the transfer of technology and repurchase  

     of auctioned facilities.

ㆍ Major disruption in the supply of masks occurred because of the outbreak of COVID19 while securing the product

     bion line – Acquired the certification for KF94 masks, and then produced and supplied the masks (allocated

     production experts)

ㆍ Completed the registration with US Food and Drug Administration (FDA) and the certification by EU Conformitè E

     uropëenne (CE) for pioneering overseas markets for export

ㆍ Judged that the survival of the new business depended on the uniform improvement of quality and reduction of 

     cost through automation of production – Promoted “Smartization of the mask factory”
