The success of the new construction products calls for a high-quality and well-managed product development process. Thus, this study aims at defining the basic steps of a NPD （new product development） process designed for floor coverings and evaluating its applicability. To this end, the product development methods of the leading companies in the construction sector in Turkey have been analyzed. Also, a questionnaire has been conducted to determine which of the steps of the proposed methodology are currently being realized and which are not or cannot be implemented. Finally, based on this information, certain suggestions have been made as to what can be done to enhance the NPD processes of the companies＇ subject to evaluation.展开更多

When connected in an advantageous environment for survival, effective relaxation and recovery from fatigue are brought about as further physiological functions, rather than a simple stress-free situation. The aim of this study is to clarify the significance of the visual stimulation of indoor floor plants placed in an office floor space. We examined how the green covering factor and gaze distance to indoor floor plants placed on the floor influenced thermal sensation. The thermal environment conditions were set at 3 levels, 25°C, 28°C, and 31°C and the floor and air temperature were homogenous. We set up 8 office floor plans that had no visual stimulation and used indoor floor plants including pachira, monstera, butterfly palm, yucca elephantipes, weeping fig, umbellate, and snake plant for a visual stimulation. The gaze distance, measured from the center of the subject presented with a visual stimulation and the center of the plant, was set at 3 distances: 2.0, 4.5 and 8.0 m. When the conduction-corrected modified effective temperature (ETF) was below 26°C, the visual stimulation of the indoor floor plants umbellata and monstera, which have a silhouette with low leaf density and rounded leaves, were shown to mitigate the sensation of being cool. The visual stimulation of indoor floor plants with rounded leaves, such as, pachira, monstera, weeping fig, and umbellata, were shown to decrease the feeling of discomfort. For a gaze distance below 4.5 m, a green covering accounting for less than 5% was shown to be necessary for mitigating the sensation of being cool and improving the feeling of discomfort.展开更多
