화생방 보호복 개발을 위한 사용자 중심 설계 및 착의 평가 = User-Centered Design Approach and Wearability Evaluation of CBRN Protective Clothing

다국어 초록 (Multilingual Abstract)

This study designs and evaluates user-centered protective clothing for chemical, biological, radiological, and nuclear (CBRN) hazards. The clothing was constructed in two separate sections (top and bottom) to enhance mobility. Although the design separates the top and bottom, the top was sufficiently lengthened to overlap with the bottom, thereby preventing the infiltration of hazardous substances. Gussets were applied to the side and underarm seams to prevent upward shifts. To accommodate dynamic movements, the back and sleeves were integrated into a single pattern, thus enabling flexibility and skin deformation. The bottom incorporated a three-dimensional (3D) knee structure, a lowered front waistline, and an elevated back waistline to relieve abdominal pressure. dditional ease was provided at the waist, and X-shaped suspenders were designed to prevent slippage. All openings were sealed with secure closures to prevent hazardous exposure. A virtual fitting assessment based on a 3D simulation confirmed the appropriate spacing between the body and clothing. Wearability tests yielded favorable results in terms of donning and doffing performances, hood comfort, ease of movement, and the suspenders’ pressure distributions. The findings indicate that the proposed design balances between protection and comfort, thus providing a valid foundation for the future development of ergonomically optimized, user-centered CBRN protective clothing.
