본 연구는 안면 마스크 착용에 따른 피부 스트레스 인식도와 뷰티 케어 현황조사를 목적으로 2021년 3월 11일-3월 27일 까지 210명을 대상으로 온라인과 오프라인을 이용하여 설문조사를 실시하였다. 수집된 자료는 SPSS 25.0을 이용하여 Cronbach's α, Frequency Analysis, chi-square test, One way Anova로 분석하였다. 코로나19 기간 중 일일 평균 마스크 착용 시간은 43.8%가 7시간 이상이며, 마스크 착용에 의한 피부 스트레스 인식도는 30대(M=4.27)와 서비스직(M=4.64)이 가장 높고 여드름, 피부 트러블(M=4.47) 고민이 있는 사람이 스트레스를 높게 인식하였다. 홈 케어 시 중요 요소는 클렌징(67.6%)이, 뷰티 케어 현황에서는 피부 관리(36.7%)가 가장 높았다. 뷰티 케어 선택 시 고려 사항은 서비스 및 고객관리 능력이 54.3%, 체형관리를 위한 방법은 운동이 45.7%로 가장 높게 나타났다. 본 연구 결과 안면 마스크의 장시간 사용으로 인해 피부 스트레스가 많이 인식되고 있으며 코로나 상황에 의해 피부 관리실 이용이 불안해짐에 따라 홈 케어 관리가 늘어난 것으로 나타났다.

In this study, we evaluated the filtering effect of the fine dust mask. Our objective research has secured credibility in the private sector. The performance of domestic fine dust masks is evaluated by three dust collection efficiencies, inspiratory resistance, and leakage rate according to KF grade in the health mask standard guidelines issued by the Ministry of Food and Drug Safety. Based on this, eight types of fine dust masks were evaluated for dust collection efficiency and face intake resistance. All masks showed good performance as the collection efficiency was 90%. The higher the KF grade, the higher the collection efficiency, but the inspiratory resistance had no correlation with the grade. According to the manufacturer's operation method, masks below the standard value may be distributed. Masks that are currently on the market have shown results that can be trusted. However, we hope that the system will be improved to validate whether the masks that meet the threshold are still being distributed.

The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.
