초록

Objectives: Currently, masks against yellow dust and fine particulates are being certified with no consideration of facial dimensional variations among children and adults. The aims of this study were to develop masks against yellow dust and fine particulates for children in Korea and provide basic data to suggest new test methods for mask certification that consider the breathing capacity of children.
Methods: A total of 730 study participants aged from six to 13 years old were recruited in the Seoul, Gyeonggi, and Incheon region. This study used a 3D scanning instrument to obtain 16 facial anthropometric data points. Literature reviews, a comparison of breathing capacity between adults and children, and analysis of children’s pulmonary physiological data were conducted in order to suggest new test standards for certifying children’s masks against yellow dust and fine particulates. In addition, types of children’s masks, choice of wearing a mask or not, and reasons for not wearing masks were surveyed.
Results: Based on a clustering analysis of participants’ facial dimensions, facial shapes were classified into three groups: small, medium, and large. The sizes of children’s masks were subtracted by using 3D sketch techniques(Large: 121.25 mm x 89.46 mm, Medium: 111.92 mm x 78.55 mm, Small: 102.13 mm x 72.87 mm). In certifying children’s mask, flow rates of 60 ℓ/m for the filtering efficiency test and 20 ℓ/m for the breathing resistance test were recommended, since children’s pulmonary physiological capacity is about 60-70% of adults’ pulmonary capacity.
Conclusions: The results of this study suggest that three mask sizes for children would be sufficient and practical for providing protection against yellow dust and fine particulates. Revising current test methods for certifying respiratory protective devices for children is important, since children’s pulmonary physiological capacity substantially differs from that of adults. Therefore, it is recommended that new test standards for certifying children’s masks be promulgated in the near future.
