  • This study was designed to develop air force mechanic parka, evaluate it, and ultimately provide functionally superior parka to the air force. The development process was 1) conducting a survey, 2) identifying problems and shortcomings of currently-supplied parkas, and 3) improving the design, pattern and materials. The newly-developed parkas were evaluated in terms of their ease of fit, clothing mobility, and insulation. Ease of fit was evaluated by subjects' sensory tests, and clothing mobility was by fitness-for-motion tests and range-of-motion tests using a Goniometer. Evaluation on insulation was conducted by thermal manikins. Findings of this study were as follows: 1. In the subjective evaluation on clothing mobility, new parkas were considered to have sufficient ease of fit while previous ones scored much lower, confirming the improvement of the new version. 2. Both subjective tests and ROM measurements on fitness for motion verified the superiority of the new parkas. 3. Insulation tests found that although insulation capability of newly-developed parkas was at a similar level to those of the previous ones, their insulation capability per unit weight was superior, demonstrating that new parkas were better at blocking heat conduction. When making changes in parka patterns and designs to enhance the mobility, it was necessary to maintain the insulation function. The new parkas developed by this study was verified to be superior to the previous ones in their insulation and clothing mobility.

  • 본 연구의 목적은 의복의 기능성 측정의 객관적 평가를 위한 관절각도측정의 방법들 간에 상관관계를 분석하고, 컴퓨터를 이용한 측정방법을 개발, 이를 기존의 방법과 비교, 분석함으로써, 의복의 기능성 측정 및 기능적 디자인 개발에 기여함에 있다. 미국 Kansas 지역의 전문 소방수를 대상으로, 선택된 10가지 실험동작에서의 관절각(range-of-motion)을 computer-aided method, Leighton flexometer, goniometer를 사용하여 측정하였으며, 측정순서는 무작위 순서(random order)로 하였다. 독립변인으로는 3종류의 측정방법(computer-aided method, flexometer, goniometer)이며, 종속변인으로는 선택된 동작에서의 관절각(range-of-motion)이다. 또한 상관분석(correlation analysis)을 실시하여, 상관계수(correlation coefficient)를 측정한 통계처리결과, 각 측정방법들 간에 긍정적이며 유의적인 상관관계가 있는 것으로 나타났다.

  • This study compared and studied the clothing mobility of two types of aerobic clothes - those made of currently popular stretch materials and those made of new stretch materials that were specially developed for this study. The focus of the comparison was on the range of joint movement during activity, and the physiological burden imposed on the body by the clothes. In total, 18 experiments were carried out under controlled conditions in an artificial climatic chamber with a temperature of $25{\pm}1^{\circ}C$, air humidity of $60{\pm}5^{\circ}C$ and negligible air movement. Each exercise program consisted of a 30-minute of aerobic workout and a 20-minute rest following the exercise. Measurements were taken to determine the following: physiological reactions (whole-body and local sweat rates), subjective sensations(of temperature, humidity, comfort, tightness, and clothing wetness), joint angle(measured with a goniometer), and so on. The results of the study us as follows: Material B excels in clothing mobility. Material C excels in sweat absorbency and drying speed. Material A was found to be the hottest material, while material C was found to be slightly hot through the analysis of the change in pre- and post-exercise bodyweight(= amount of sweat). Regarding the amount of evaporated sweat, material A>material C>material B. Material B produced the smallest amount of evaporated sweat. The wider the range of joint movement, the smaller the amount of sweat and the lower the average skin temperature.
