This paper presents a novel design of the printed hyperpolar-transformed Sierpinski Carpet (HSC) antenna. By hyperpolar transforming the Sierpinski carpet geometry, from isotropic scaling symmetry to equiangular scaling symmetry, we get improved performance rather than that of the general Sierpinski Carpet antenna. The design parameter and performance of the proposed monopole antenna are investigated by simulation. And we showed that proposed HSC geometry gives more freedom for wideband antenna design such as flare angle, (angular)scale factor.

This research was designed to develop the rapid propagation technology of zoysiagrass using carpet production and to provide turf-growing farmers with efficient cultivation methods thor carpet production. Turfgrass cultivar tested in cadet production by seeding was Z. japonica cv. Zenith. Since the surface coverage rate reached to 85% in 2 months after seeding at the rate 6g/$m^2$ in the early part of July, carpet production using ‘Zenith’seeds would be possible to produce within within the same year. Thrfgrasses tested in carpet production by vegetative propagation were Z. japonica, medium type Z. matrella, fine type Z. matrella, and medium type Z. japonica. Planting rates of vegetative parts (sprigs) were 1.2L/$m^2$, 2.4L/$m^2$, 2.5L/$m^2$, and 5L/$m^2$. Two different sizes of sprig were used; 1~2 nodes and 3~4 nodes. Surface coverage rate was 90% in one year after planting at the rate of 2.5L sprigs of medium type Z. japonica. Therefore, the use of sprigs with 3~4 nodes at the planting rate of 2.5L would be suitable for the carpet prodcution. Three months old zoysiagrass carpet (Zenith) was overseeded with Kentucky bluegrass, perennial ryegrass, and tall fescue at two different overseeding rate. Surface coverage rate was the highest (80%) at the plot overseeded with perennial ryegrass that showed the earliest germination. Suitable overseeding species for the rapid sod formation at the early stage of establishment were tall fescue and perennial ryegrass and desirable overseeding time was from early to middle of September.

This study considers aesthetic characteristics by examining red carpet dress in China film festival. The research methods were quantitative and qualitative analysis of red carpet dress images collected from 2015 to 2019 on websites according to four criteria following previous research on red carpet dresses. The results of the study are as follows. First, the analysis of red carpet dress silhouettes showed that A-line silhouettes, slim silhouettes, and mermaid silhouettes appeared. Second, in terms of colors, one color, black, represented a higher proportion of the dress colors than the combination of different colors. Third, soft texture occupied the highest proportion of material textures, and combinations of materials with different textures were also used. In the case of patterns, the proportion of dresses without patterns was high, and natural patterns were found in the largest proportion. Beads and sequins accounted for most of the dress details, and the analysis showed that various detail types such as embroidery, slits, ruffles, and belts were used in the red carpet dresses. The aesthetic characteristics of the red carpet dresses worn at the China film festival were analyzed as sensual, elegant, decorative, and simple.

With the expansion of the Russian Empire southward in the nineteenth century, connoisseurs, art historians, and scholars in Russia began to pay attention to carpet traditions in the new territories of the Russian Empire in Turkestan. In journals and other specialty publications, they underscored a need to establish claims to authority over the knowledge of the traditional craft. They were highly attuned to parallel accounts of carpet weaving from regions that had a longer history of research and collecting of carpets. In contrast to the situation in Western Europe or the United States, commentators bemoaned the fact that the public and even professed experts in Russia did not properly appreciate carpets from the Caucasus and Central Asia. These scholars articulated a need to establish authority over the carpet weaving traditions of Russia's colonial possessions, resulting in a push toward a serious study of carpet weaving as a legitimate field of inquiry. This paper uses published sources on early carpet scholarship from the late nineteenth and early twentieth centuries to examine how carpet weaving traditions in Central Asia entered an imperial discourse of knowledge. It argues that attempts to understand and categorize carpet weaving as an art form occurred along two fronts. Intellectuals and scholars attempted to wrest control over the locus of knowledge from experts in the West as well as from local weavers. In the process, they established a distinctly imperial vision of carpet weaving in contrast to competing imperial discourses and over traditional forms of knowledge.

The purpose of this study is to establish the basic materials necessary for red carpet fashion design by examining the formativeness and fashion images of red carpet dresses at film festivals in the Great China Region. For the purpose of this study, research methods include a literature review on the origin and significance of red carpet dresses, the characteristics of film festivals in the Great China Region and their red carpet dresses as well as an analysis of the formative features and images of 615 red carpet dresses collected from each film festival official homepage, diverse media articles, and online search sites (www.google.com, www.hao123.com). The research finding can be summarized as follows: First, the formative features of red carpet dress designs were analyzed herein. It was found that the most frequently appearing type of silhouette was straight followed by hourglass and bulk in order. More specifically these included fit and flare, mermaid, trapeze, and slim in order. For the neckline styles, strapless was the most frequently seen followed by camisole, jewel, and one shoulder. Solid colors were more often seen than multiple colors. Bk, W, R, and YR were the most frequent main solid colors in order. Solid materials were frequent as well, such as soft and shiny materials. Non-patterned and unadorned styles were most frequent as for pattern types and details and trimmings. Second, the fashion images of red carpet dresses in the Great China Region were analyzed. The most frequent images were elegant, feminine, ethnic, modern, classic, avant-garde, others, mannish and sportive, in order.

In this study, the burning behaviours of five different kinds of carpet samples covered with nylon, PP (polypropylene), PTT (poly(trimethylene terephthalate)), wool fabric and NW (nylon and wool) were evaluated by using the cone calorimeter having a radiant flux of 50kW/$m^2$. And the combustion gas toxicity was evaluated according to KS F 2271 test method. As a result of the cone calorimeter test (KS F ISO 5660-1), nylon carpet samples were ignited most easily. In ignition ability or initial flammability, NW carpet samples showed the highest value. In heat release rate (HRR), fire intensity, PP carpet samples were larger than any other samples. Nylon carpet samples were the highest smoke production rate, while N/W carpet samples the lowest. The following were in mass loss rates: NW > wool > nylon > PP > PTT. CO (carbon monoxide) was one of the most toxic gases released from the combustion. PTT carpet samples gave rise to the highest CO concentration, while NW carpet samples the lowest. In addition, PP carpet samples caused the highest $CO_2$ (carbon dioxide) concentration, while NW carpet samples the lowest. Toxicity of the gas produced from carpet samples was determined by the mouse stop motion, and it resulted in the fact that the combustion gas of PTT carpet samples was more toxic than that of any other samples.

There are three carpet-like Codium species with a broadly expanded thallus reported from Korea and Japan: C. latum Suringar, C. tapetum Y. Lee, and C. tenuifolium Shimada, Tadano and J. Tanaka. During surveys of green algal diversity, we encountered a Codium species with carpet-like thalli from several sites on Jeju Island. To confirm the taxonomic identity of these specimens, we studied the morphological features and obtained rbcL gene sequences. The morphological and sequence data indicated that the carpet-like Codium specimens from Jeju are C. tenuifolium from Japan, but distant from Japanese C. latum. We propose that the carpet-like specimens from Jeju should be renamed C. tenuifolium, instead of C. tapetum or C. latum. C. tenuifolium is characterized by a tenuous, carpet-like and erect thallus with a very short and slightly compressed stipe arising from a discal holdfast, sub-pyriform and clavate utricles with a tumid and swollen apical head, and globular or sub-globular gametangia issued at the basal portion of the utricles.

In this study, we have evaluated the hazardous factors of fires such as heat release rate, smoke density, ignition temperature, and flammability of carpet and curtain used in the public facilities. As a result of flame retardant treatment, the heat release rate of materials treated with flame retardant was lower than that of not treated. However, the smoke density of treated materials was higher than that of not treated. Also, we have investigated the fire characteristics of used and unused carpet. As a result, the heat release rate and the smoke density of used for 3 years carpet were higher than those of unused carpet. The distinct differences of flammability and ignition temperature between used and unused carpet were confirmed.
