Traffic accidents among children have been decreasing after the installation of yellow carpets. However, the explanatory power of the causal relationship between yellow carpet installation and traffic accidents is still insufficient. The yellow carpet effect was analyzed in greater depth using virtual reality (VR) simulation experiments in various situation that could not be evaluated in existing actual vehicle research studies due to difficulties or risks in implementation. A target site where an actual yellow carpet was installed was selected and, implemented into a virtual environment. Subjects were made to, were gaze measurement equipment and ride the simulator. The visual/driving behavior before and after yellow carpet installation was compared, and a t-test analysis was performed for statistical verification. All the results were found to be statistically significant.

Indoor air differs from outdoor atmosphere since it contains chemical and physical contaminants from building materials. This study deals with the biological effects of volatile organic compounds (VOCs) released from synthetic fiber carpet materials. One group of Tradescantia inflorescence was exposed to VOCs from the carpet sample in the environmental test chamber, while the other inflorescence group was exposed to a TO-14 standard gas mixture (1 ppm) for comparison. After the exposure, VOCs from the carpet were analysed by the desorber/GC/MS method, and micronuclei in the pollen mother cells of Tradescantia were scored under a microscope $({\times}400)$ to evaluate the genotocixicity induced by the exposure to VOCs. The chemical analysis confirmed that a total of 12 VOCs were released from the carpet materials, among which stylene $(71.9{\mu}g\;m^{-3})$ and toluene $(49.6{\mu}g\;m^{-3})$ were in the highest concentration. Twenty four hours of exposure to VOCs from the carpet in the environmental test chamber resulted in a micronucleus frequency as high as $7.73{\pm}0.75MCN$ per 100 tetrads, which was similar to that induced after exposure to the TO-14 standard gas mixture (1 ppm) for 4 hours. Meanwhile, two hours of exposure to the standard gas mixture did not cause a significant increase in the genotoxicity compared to the spontaneous micronucleus frequency. This result indicates that exposure for a long time to the air contaminated with VOCs from the carpet materials causes a genotoxic effect. The biological-chemical combination analyses in the study proved to be an effective tool for monitoring the indoor air contaminants.

사회가 고도록 발달하면서 사람들의 생활공간은 대부분 사무실이나 가정에서 보내는 시간이 하루의 80-90% 이상을 차지하고 있다. 대부분의 시간을 특정공간에서 보내게 되므로 건강과 편리함을 위해 설치되고 있는 가구나 카펫, 그리고 기타 다양한 제품에서 방출되는 휘발성 유기화합물에 대한 관심이 증가하고 있다. 한 예로, 미국 소비자 생산품 안전 위원회 (U.S. Consumer Product Safety Commission, CPSC)는 1988년부터 1990년 초까지 206가구에서 335명의 주민들로부터 새로 설치된 카펫에서 방출되는 다양한 화학물질로 인한 여러 가지 고통을 접수하였다.

This paper examines the combinations of factors influencing the absorption characteristics of theatre chairs. One-tenth scale model chairs and listeners that closely approximated the absorption characteristics of full scale theatre chairs were used to measure the interactive effects of the test variables on the chairs absorption characteristics. The test variables were the type of chairs, the row spacing, as well as the presence of people and carpet. The variations of absorption increments with varied row spacing tended to be smallest when the chairs were less absorptive, i.e. with less carpet or occupants. The incremental effects of adding occupants or carpet averaged over three row spacings varied over frequency.

Recently, interest of consumers in home furnishing products has increased steadily because of the increased time spent at home due to COVID-19. Among them, carpets made of various materials and technologies are becoming popular interior item. Academic and industrial sectors agreed on the need to produce premium design carpets. Prior research on carpet design was mostly focused on patterns, history, with insufficient investigations on the type. Therefore, the purpose of this study was to provide basic data to develop premium design carpets by analyzing their expression types. To analyze expression types, this study covered about 400 design carpets surveyed on the websites of eight major carpet companies from January 2021 to March 2021. Based on the analysis results, the five expression types of are as follows. Firstly, the expression type was expressed in various atypical forms that was deviated from the formal form. Secondly, it was a type that improves visual and tactile effects through a variety of 3-D textures. Thirdly, it was a type of diversification of motifs, which was based on the works of artists and designers in various fields. Fourthly, it was a type that combines two or more different materials and techniques. Finally, it was a modular type that can be applied in various ways to various spaces. Based on the analysis results of this study, it is hoped that the data will be helpful to produce premium design carpets in Korea.
