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.

Interaction between sedentary and nomadic cultural traditions has played an important role in the centuries-old history of applied arts in Uzbekistan. By the late 19th and early 20th century, driven by urbanization in the region and the gradual transition of nomadic and semi-nomadic peoples to sedentary lifestyles, many industries and traditional cultural forms of formerly nomadic ethnic groups disappeared. Nevertheless, their role in shaping the national cultural identity of the Uzbek people is great. This is true in relation to one of the largest ethnic groups in Uzbekistan, the Kungrats, whose applied art represents a unique, viable, and yet little-studied phenomenon in the national culture of Uzbekistan. The article reviews carpet weaving, one of their surviving crafts, exemplified by qiz-gilam, a unique type of rug made using a combined technique. This study helps to show the nature of historical and cultural interrelations in the carpet weaving of Central Asian peoples and their cultural contacts with the carpet art of neighboring regions more widely and objectively. An important theoretical result of this study is the creation of criteria and tools for identifying qiz-gilam carpets. This allows us to bring clarity to the yet undeveloped system of their identification in museum and gallery practice.

This paper describes the experiments for investigating the effects of thermal stability of several commercial carpet mate materials. The melting point and thermal decomposition temperature was measured by means of a differential scanning calorimeter(DSC) in air condition. The DSC data and burning test results of nylon bulked continuous filament(N-BCF) yarn 100%, nylon(NY), polypropylene(PP), and a new material named polytrimethyleneterephthalate(PTT) were analysed to obtain the effect on their thermal stability. Conclusively, we observed that PTT and PP were approximately $380^{\circ}C$ and $240^{\circ}C$ to start the thermal decomposition, respectively. In other words, PTT is thermally the most stable material for carpet manufacturing.

Background: Musculoskeletal pain (MSP) is a common and disabling problem among carpet weavers and is linked to physical and psychosocial factors of work. This study aimed to determine the prevalence of MSP, its psychosocial risk factors, and association of pain in each pair of anatomical sites among carpet weavers. Methods: A cross-sectional study was performed among 546 hand-woven carpet weavers in rural small-scale workshops of Iran. Data were collected by using parts of a standardized CUPID (Cultural and Psychosocial Influences on Disability) questionnaire focused on MSP in 10 body sites, including the low-back, neck, both right and left shoulders, elbows, wrists/hands, individual, physical and psychosocial risk factors. Statistical analysis was performed applying logistic regression models. Results: Prevalence of MSP in at least one body sitewas 51.7% over the past month. The most common sites were low back and right shoulder pain 27.4% and 20.1%, respectively. A significant difference was found between the mean number of painful anatomical sites and the level of education, age, physical loading at work, time pressure, lack of support, and job dissatisfaction. In pairwise comparisons, strongest association was found between pain in each bilateral anatomical site (odds ratio = 11.6-35.3; p < 0.001). Conclusion: In home-based workshops of carpet weaving, psychosocial factors and physical loading were associated with MSP. This finding is consistent with studies conducted among other jobs. Considering the preventive programs, the same amount of attention should be paid to psychosocial risk factors and physical loading. Also, further longitudinal studies are needed to investigate the relationship of psychological factors.

It was studied a compared estimation of the fire risk of the three kinds of the interior materials, such as a resist carpet, a resist-after-treatment plywood and sofa leather. Toxic gases, CO, CO2, NOx, SO2, HCN, HCI were detected during the combustion of the samples. A resist-carpet was more combustible than the resist-after-treatment plywood and sofa leather in the combustion characteristics and has a blow-up-combustion of combustion in all the samples. The generation of CO reached the lethal doses in minute after the combustion was begun. NOx and So2 were detected not more than each of the lethal doses, while HCN was detected in the carpet 20.6 times than the sofa leather, and 4.6 times than the resist-after-treatment plywood. HCI was detected in the carpet 4.48 times than the sofa leather and 2.47 times than the resist-after-treatment plywood. It is conclusion that the carpet was the highest in the fire risk among the three kinds of the interior materials.

Pedestrian safety was recently highlighted with a yellow carpet, a yellow-colored pavement material prepared for children waiting for signals for pedestrian crossing, without validation of its efficiency in practice. It was a promising device likely to assist highway safety by stimulating pedestrian to step on the yellow-colored area; it was generally called nudge effects. This paper delivers a study conducted to check the effectiveness of yellow carpet in three different aspects in vehicle driver's perspective by applying the newly introduced information technology (IT) service: Visual Attention Software (VAS). It was assumed that VAS developed by 3M in the United States should be able explain the Korean drivers' visual reaction behaviors since technology embedded in VAS was developed based on and proved by other various international countries and continents in the world. A set of pictures was taken at thirteen different field sites in seven school zone areas in the Seoul metropolitan area before and after the installation of a yellow carpet, respectively. Sets of those pictures were analyzed with VAS, and the results were compared based on the selective safety measures: the likely focusing on standing pedestrians (waiting for a pedestrian's green signal time) affected by its background (yellow-colored pavement) contrasting him or her. The test results from a set of before-and-after comparison analyses showed that the placement of yellow carpet would (1) increase 71% of driver's visual attention on pedestrian crossing areas and (2) change the sequential order of visual attention on that area 2.4 steps ahead. The findings would enhance deployment of such promising efficiency and thus increase children safety in pedestrian crossing. The result was promising to highlight the way to support the changes in conservative traffic safety engineering field by applying the advanced IT services, while much robust research was recommended to overcome the limitation of simplification of this study.

Traditional Kurdish weavings are among the world's most ancient living textile traditions. One of the largest regional ethnic and linguistic groups, Kurds have inhabited a significant part of Western Asia for millennia. Historically, Kurdish territories were crisscrossed by old and important trade routes, including the Silk Roads. This led to the formation of some of the most significant Kurdish artistic and cultural traditions, including textiles, which influenced and were influenced by those of other non-Kurdish ethnic groups from Caucasia to Central Asia and beyond. One example of Kurdish carpet traditions born in the eighteenth century at the cross-sections of Safavid (1501-1736) urban carpets workshops and centuries-old indigenous Kurdish tribal/rural weaves is senneh gelim or sojaee. A finely flatwoven carpet that was exchanged regionally and internationally as a diplomatic gift and a highly prized commodity. Although in decline, senneh gelims continue to be made by Kurdish women weavers in their original birthplace Sanandaj, the provincial capital of Iranian Kurdistan to date. This study adopts an inter-disciplinary approach to present an image of senneh gelim and women gelim weavers, tracing the developmental trajectories of the craft from the eighteenth century to the present time by drawing on extant art-historical and social scientific studies along with primary ethnographic data collected in Iranian Kurdistan (2018-2019). It investigates the craft tradition's historical origin, various aspects such as techniques, materials, aesthetics, functions, and meanings, and how these transformed over time. Additionally, the paper looks at the social contexts of production, focusing on women carpet weavers and how their socioeconomic and cultural situation has formed senneh carpet production in the past and present and the implications for long-term preservation.

The article deals with issues related to the tradition of carpet production on the territory of Kazakhstan where, for the most part, tribes engaged in nomadic livestock raising lived. Analyzing the technological component of this traditional craft, the author focuses on the main factor that influenced carpet weaving along with arts and crafts-the nomadic method of production of the Kazakhs. The study of the ideological component that accompanies the process of making various types of carpets allows us to conclude that it has a sacred meaning and subordination to myth, rite, and ritual. At the mythmaking level, the process of making carpets, like any other activity among nomads, personified the process of creating the world, the marriage of Kok-Tengri (Heaven) and Zher-Su (Earth), and the creation of the Cosmos from Chaos. The process of carpet weaving, as well as the process of making felt, symbolized the act of creation, the marriage of Heaven and Earth, and male and female principles. The study of various types of ornaments that Kazakhs and their ancestors used to decorate carpets allows us to conclude that the ornament applied to carpet products was the bearer of the most valuable information about the mythological worldview of the people. Carpets in their structure reproduced the structure of the Universe, which has a binary, ternary, and quaternary system. The ornament has turned into a kind of coded text, reflecting ideas about the cosmogonic structure of the Universe and an awareness of the harmony of the world. The location of Kazakhstan on the northern routes of the Sogdian Road (Great Silk Road) allowed the spread of various ideas, due to which carpet weaving was influenced by other peoples in technical and stylistic design.

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.
