Workers on construction sites are exposed to multiple and varied threats. Of those, climatic factors such as high/low air temperatures and high/low humidity have a bad mental and physical health effect on workers. Especially, work in hot environment has a tendency to cause fatigue, reduce productivity and increase the incidence of accident. So, the purpose of this research was to understand working clothes and working environment of workers at a construction site in summer. The depth interview was performed by 45 workers of 4 different construction sites and the results were as follows. Workers wore average 4 items as clothing(upper, lower) and average 5 items as personal protective equipments(PPEs). They answered "head" is the hottest body area and must be protected during working. This means the necessity of development in safety hat. In addition, it should be developed working clothes and gaiters for alleviating heat stress and safety shoes for diminishing weight. It is expected that this research plays basic and important rolls to develop PPEs for reducing the heat stress of construction workers.

This study proposed a color scheme that is harmonious with the working environment of industrial sites using Birren's color harmony theory for color planning. To apply the Birren's color harmony theory to working clothes, the basic colors were chosen, and six of the eight harmony formulas of Birren excluding achromatic colors (white + grey + black) and solid color harmony (solid colors + white + black) were used to form a palette for each case. For the basic colors, the color chips of four dominant colors (yellow-green, sky-blue, blue, and violet), which were chosen from a field survey for preferences in the first step, and the production of materials in the second step were collected through the PANTONE color chips. The selected color chips were PANTONE 13-0550 TPX, PANTONE 15-4105 TPX, PANTONE 18-3949 TPX, and PANTONE 19-3720 TPX. These color chips were scanned and their RGB values were extracted through Photoshop CS. Then the colors were arranged in accordance with the Birren's color harmony formulas (Color+Tint+White, Color+Shade+Black, Tint+Tone+Shade, Shade+Tone+Black, Shade+Tone+White, and Tint+Shade+Tone+Gray). In addition, the proposed palette color schemes were applied through Birren's color harmony formulas using Texpro V 10.1 textile to the schematization of working clothes that were designed in the previous study. Palette formation in line with Birren's color harmony formulas provided scientific color arrangement results. Visually presenting the color scheme of working clothes will help the color selection of working clothes in tune with the circumstances of industrial sites.

It is a normal circumstance to have high temperature and high humidity in Greenhouses even though these climates are changed by the area, season, climates, the size of the greenhouse, and the crops being raised. Workers in the greenhouses have complained about their uncomfortable work environment and discomfort from the hot conditions, including sunburn. The farmers' ailments are not significantly different between those working in the in greenhouses and those working in the fields. The Farmers' syndrome was almost two times higher for women than those of men for greenhouse workers. This study was developed for functional fatigue clothes for plastic greenhouses which are known for high temperatures and humidity. The ergonomic function and thermal comforts of fatigue clothes were evaluated in the climatic chamber($30.0^{\circ}C$, 70.0%R.H.). The current fatigue clothes which are made of cotton or nylon were purchased at the market. The developed clothes are made of highly absorbent and high speed drying polyester. And these fabrics have excellent elasticity. In this study, the functional fatigue clothes were designed with longsleeved sport shirts and Full length pants. Tre, Tsk, Hcl, HR and the personal subjective sensations such as heat, humidity, and comfortableness were significantly lower when subjects wore the developed clothes made with polyester than the previous attire.
