Development of a quantitative system for subjective evaluation of tracked vehicle crew jackets

The purpose of this study is to develop a quantitative evaluation system that reflects the required performance factors that are important for a tracked vehicle crew jacket. We identified and analyzed the necessary performance factors obtained from a focus group interview and a questionnaire survey. Further, we proposed a new method of calculating weights and developed a quantitative evaluation system. This system featured an equation that calculated the evaluation score out of 100, using the factors percentages in the total factor as factor weights. The systems application was verified by the assessment of subfactors by active-duty soldiers, and by confirmation that the results of the developed factor scores reflected the proposed development direction. The study is significant for its provision of a comprehensive and quantitative evaluation system which has not existed before for protective clothing design, as well as for the verification of the systems application through the process of protective clothing development. The quantitative evaluation system and its development process described in this study may be referenced and widely deployed due to its use of a Likert scale, which is commonly used as a subjective sensory evaluation tool.This work was supported by the Defense Agency for Technology and Quality (DTaQ) grant funded by the Ministry of National Defense (Civil and Military Technology Cooperation Project No. 18-force support-01)

Digital-Based Healthy Bra Top Design That Promotes the Physical Activity of New Senior Women by Applying an Optimal Pressure

A bra use can reduce physiological and physical functions because of clothing pressure, which can be a problem for new senior women starting to lose physical function. The present study presents a bra top design development method for promoting new senior women’s physical activity by identifying problems related to bras’ effects on women’s health and minimizing clothing pressure. The analysis utilized the 3D scan data of 42 adult women (age range: 50s) from the 5th Size Korea Project. Bra top design elements were extracted based on new senior consumers’ needs. We developed an average wireframe reflecting the new senior’s physical characteristics, and a standard body form was developed through surface modeling. To produce a consumer-oriented bra with a body shaping effect and reduced clothing pressure that would not affect physical activities, a three-dimensional pattern was developed applying an optimal reduction rate of 80%. To verify the bra’s adequacy for the body form of new senior women, two market-available bras were selected and fit-compared to the developed product. The developed bra received higher expert appearance evaluation and 3D virtual clothing evaluation scores. This study is significant because by using virtual fitting technology, it provides foundational data to quantify the quality of fashion products
