In this paper, experiments to develop working clothes and evaluated, including the current and material-improved working clothes in relation to physiological functionality measurement. Experiments were conducted on subjects after wearing working clothes in an climate chamber, and the thermo-physiological response, such as human body temperature, micro-climate within the clothes, blood pressure, heart rate were measured. In this manner, the physiological functionality of improved working clothes was compared with that of current working clothes and evaluated. The summary of obtained results is as follows: For physiological functionality evaluation through material-improved working clothes, P working clothes showed significantly lower rectal temperature than C working clothes. For mean skin temperature, P's skin temperature was significantly higher than C's in the second half of the experiment. P working clothes's temperature around the thighs in Micro climate was significantly lower than that of the C working clothes. Also, humidity within the clothes showed similar trends. During the exercise period, C working clothes showed higher blood pressure than P, but P showed higher heart rates than C. Also, the oxygen uptake amount was higher in C than P during the exercise period, it explains that the energy consumption amount of P working clothes was smaller than that of C working clothes. Of the subjective evaluation, for temperature sensation, workers wearing P working clothes felt cooler. For humidity, C working clothes showed more humidity. For comfort, P working clothes were better, and for sense of fatigue, workers felt less tired wearing P working clothes. From results above, we can see that physiological functionality improved in the material-improved working clothes in the working clothes for construction site workers. The improvement of working clothes through functionality improvements not only will provide personal pleasantness to constriction site workers, but will also generate efficiency and productivity improvements at construction sites. All in all, the continuous study of functionality improvements in working clothes taking into consideration the human body's physiological responses is required.

The purpose of this study was to determine the characteristics of an experimental protective clothing material with regard to comfort and isolation from the hazardous heavy metals produced in municipal waste incineration. An analysis was conducted on the total concentrations of heavy metals in some parts such as surface, middle layer, and interior for the treated fabric, and the untreated one, and working clothes. We conclude that the processed fabric with charcoal for working clothes showed the least exposure to heavy metals of the three. Working clothes worn by workers during waste incineration were much more contaminated than the untreated and treated materials. The material of working clothes could be chosen according to the function with regard to its original chemical characteristics, which are the proper results of the dyeing process. The processed fabric material has high degrees of moisture regain, thermal insulation, water vapor penetration, and antibacterial function; consequently, it is much more comfortable to wear. The fabric material proposed in this research contributed much more to blocking heavy metal concentrations (such as Cd, Pb, Cu, Cr, Zn, Mn) than did the fabric of working clothes at present. Consequently, we strongly suggest that the material of working clothes be upgraded by adopting the above-mentioned charcoal-processed fabric. Materials of working clothes must be improved to increase comfort and prevent harmful gas, flying dust, and heavy metals from permeating the fabrics.

카멜레온은 미끈한 몸통과 화려한 색 띠들을 가진 작은 도마뱀을 말하는데 빛, 온도, 기분에 따라 색이 변화하는 것이 특징이다. 또한, 변덕스러운 사람, 요염하고 매혹적인 사람, 속물적이면서도 상황에 재빨리 대처하는 사람 등을 일컬어 카멜레온이라고 하기도 한다. 본 연구의 목적은 상황에 따라 색이 변하는 카멜레온 이미지를 요염한 변덕장이들의 섹시한 스타일로 비유해서 Wearable Art에 실루엣, 색, 텍스처 개발 기술을 접목하여 표현하고자 한 것이다. 연구방법은 카멜레온의 사실적, 개념적 특징들을 Wearable Art 작품으로 표현해 나가는 단계에서 특히, 옷감 표면에 다양한 제작 기술들을 실험해 보는 과정으로 진행되었다. 작품 이미지 컨셉은 'sensuality', 'tempting', 'splendid', 'brilliant', 'fascinating' 등으로 표현했고, 연구자의 미래지향적 기호와 움직임을 통한 편하고(comfortable) 즐거울 수 있는(enjoyable)개념 역시 포함되도록 하면서 작품 완성도를 높였다. 디자인 및 제작 포인트는 실제 카멜레온의 전체 라인, 색, 표피 질감 등 그 특징들을 분석하여 본 작품의 형태, 색, 텍스처 등을 통해 상징적으로 표현하도록 하였고, 동시에 요염한 변덕장이 카멜레온의 이미지가 암시적으로 나타날 수 있도록 하였다. 작품 실루엣은 바디컨셔스 라인(body-conscious line)이다. 이것은 카멜레온의 날씬하고 미끈한 몸체를 이미지화 한 것이며 동시에, 속세적이면서도 미래적인 이미지가 암시적으로 표현되도록 한 것이다. 카멜레온 등뼈가 드러난 것을 드레스 등이 노출되도록 하여 표현하였는데 이것은 동시에 관능적이고 요염한 카멜레온 이미지를 나타내는 것이다. 카멜레온의 유선형 머리부분 표현은 완만한 삼각형 모양의 후드패턴을 통해, 카멜레온의 길게 말린 꼬리 표현은 불규칙적인 플레어의 햄 라인으로 처리하여 상징적으로 표현하였다. 카멜레온 색들은 선명한 비비드 톤이면서 동시에 빛 또는 기분에 따라 색이 변화하는 것이 특징인데, 작품 제작 과정에서도 빛과 각도에 따라 드레스 색이 조금씩 다르게 보이는 효과를 가장 중요하게 연구하였다. 검정색 쉬폰 위에 퓨셔(fuchsia)색 작은 벨벳 물방울 무늬가 박힌 소재를 주 소재로 하여 표면에 입체적인 텍스처를 줌으로서 빛의 각도에 따라 두가지 색이 섞여져서 전체적으로 색이 다르게 보이는 착시 결과를 가져왔다. 허리에서의 빨강색과 파란색 계열의 다양한 스톤들은 실제 카멜레온 스킨 이미지와 더불어 돌출된 입체감과 그라데이션 효과로 인해 움직임에 따라 색이 다르게 보이는 결과를 가져왔다. 50% 쉬폰/50% 폴리에스테르에 벨벳 다트 무늬가 들어가 있는 원단을 사용하여 옷감 표면에 탄성실을 이용한 스모킹 주름효과를 주는 기술을 접목시켜 flexible한 스트레치성 옷감으로 재탄생시킴과 동시에 소재 표면에 오돌토돌한 텍스처가 생기게 하였다. 이것은 카멜레온의 표피와 흡사하면서 동시에 몸에 밀착되는 결과를 가져와 섹시하면서도 편안한 작품 이미지 표현에도 적절한 역할을 한다. 스톤장식은 아크릴릭카보숑(acrylic cabochons)과 잼스톤(gemstones)들을 섞어서 사용했는데 카멜레온 등 표피 질감을 상징함과 동시에 색이 다르게 보이는 효과를 나타낸다는 점에서 본 작품의 포인트이다. 드레스 제작은 주로 바이어스 결을 이용한 드레이핑 기법을 이용하였는데, 후드가 앞 몸판과 연결되어 있고 불규칙적인 사각형들이 앞에서 뒤로 옆 솔기 없이 연결되어 있다. 옷은 살아 움직이는 사람이 입어서 가장 편하고 즐거우면 옷의 완성도가 가장 높다고 할 수 있다. 카멜레온 드레스 역시 움직이는 신체와 함께 색이 다르게 보이는 기법과 효과를 연구하는 과정에서 편하고 즐거운 Wearable Art를 완성할 수 있었다. 바로 이점이 입는 예술 즉, 입고 즐길 수 있는 옷에 예술미를 가미한 Wearable Art의 진미가 아닐까 생각한다.
