A hydro-geomorphologic change in a sand bed channel reach and vegetation expansion by changes in the How regime is analyzed in this study. Field and aerial photo surveys, basic hydrological analysis about flow regime change due to two dams, Andong Dam and Imha Dam, on the upstream river and computer modeling are conducted. Two Dams in the study reach have obviously affected downstream channel in many ways including the bed particle coarsening, vegetation expansion on the sandbars and following river channel braiding. The phenomenon of no vegetation on the large point bar in front of Hahwe Village seems due to disturbance of the sandbar surface probably due to the cross flow in the meander reach during the flood. Another reason for no vegetation is that the sandbar on this reach has lower subsurface water lovels, as compared with the others in the up- and downstream of the reach where vegetation expanded, which would hinder vegetation from germinating and growing on the sandbar.

The 22 m diameter Mopra telescope in Australia is being used to undertake an improved survey of the CO J = 1-0 line at 3mm along the 4th quadrant of the Galaxy, achieving an order of magnitude better spatial and spectral resolution (i.e. 0.6 and 0.1 km/s) than the Dame et al. (2001) survey that is publically available for the Southern Galactic plane. Furthermore, the Mopra CO survey includes the four principal isotopologues of the CO molecule (i.e. $^{12}CO$, $^{13}CO$, $C^{18}O$ and $C^{17}O$). The survey makes use of an 8 GHz-wide spectrometer and a fast mode of on-the-fly mapping developed for the Mopra telescope, where the cycle time has been reduced to just 1/4 of a second. 38 square degrees of the Galaxy, from $l=306-344^{\circ}$, $b=0{\pm}5^{\circ}$ have currently been surveyed, together with additional 9 sq. deg. regions around the Carina complex and the Central Molecular Zone. We present new results from the survey (see also Burton et al., 2013, 2014). The Mopra CO data are being made publically available as they are published; for the latest release see the project website at www.phys.unsw.edu.au/mopraco.

In this study, fiber-reinforced composite coil springs for automobiles were manufactured using the braiding method, and mechanical tests and damage evaluation were performed to confirm their safety. Through the analysis of the load-displacement behavior, the stiffness of the springs was evaluated to meet the specifications. In addition, the distribution of voids and the impregnation rate on the spring wire section were analyzed to clearly understand the criteria for the mechanical properties of the composite material. Moreover, the tested springs were visually inspected to confirm the damaged parts, and the failure mode was analyzed by observing crack initiation and propagation behavior of cross-sectional samples taken from the crack and failure adjacent areas of springs using SEM.

"Keunmeori", the grand headdress with various decorations attached to thickly braided and raised hair has been used as a bride's formal attire since the Joseon Dynasty, and in the modern period, new styles known as goegye and hyuche appeared as formal attire for civil weddings. Goegye was formed from a round wooden pillar wrapped with hair and decorated richly with ornaments; getting married with goegye meant that the wife was officially married. Hyuche was made by braiding the hair into two long plaits and decorating it with colorful fluttering hairpins and gold leaf hair ribbons. Hyuche was originally formal attire for a princess at her wedding, and it is thought to have been less frequently used in the private sector due to its higher cost than goegye. The style of goegye appears to have been influenced by the susik, the highest formal attire for a queen, and in particular, the decorations on the circular top part of the susik were presumed to have been similarly reproduced in folk weddings. Goegye changed in various aspects according to the social environment and atmosphere of the times, and was also used as formal attire for a prince's wife.

Soochonri tombs are assumed to be of the Baekje Kingdom in the early 5th century. We have examined 12 artifacts and 24 textiles in the four tombs. Along with hemp textiles, silk and embroidery threads were found In the Soochonri tombs. Within the hemp textiles both hemp and ramie were made using s-twist threads and the thread count distribution is calculated to be $8.5{\sim}15.5/cm^2$. Taffeta, one of the silk, can be categorized in to four types. First, the plain woven silk was made with warp and weft of the same thickness. The rates of thread count are also similar. Secondly the warp and weft are of the same thickness but has more spaces between threads. Third, the type of warp and weft is different in thickness, the thicker thread woven in the same direction. Lastly, a textile was woven with spaces the same as the width of the reed mark in every two warps. There were five compound weave found. Among them one was made with non-twisted thread for warp and s-twist thread for weft. One plain braiding with apparent spaces between threads were found. All three of the twining were made with wefts thicker than warps, barely showing the warps as a result. Textiles of the Soochonri tombs are the oldest of the Baekje Kingdom studied by far and therefore important artifacts of the Baekje Kingdom. These textiles are similar to those found in the King Muryeong's Tomb and tombs of Gaya and Shilla.

This study investigated up-styling techniques as related to wedding dress image. To find up-styles that fit well with a wedding dress, a questionnaire survey was conducted targeting hairdressers in the beauty industry, and new styles were created and suggested based on the survey results. For this, hair was slicked back without parting and combed upward. Then, using braiding techniques needed to produce a top point, styles were created to create attractive images. For up-styles that go with an elegant wedding dress, hair was parted in a ratio of 3 : 7. In addition, a roll technique was applied based on natural points by keeping the ears half-covered to create elegance. For up-styles that are perfect for a classic wedding dress, hair was parted in a ratio of 2 : 8, keeping the ears half-covered. Based on the back point, a twisting technique was applied to create classic images. It is anticipated that the study results would provide basic data needed for creating and understanding up-styles that go with various wedding dress images and make a contribution to their development.

Different method of textile fabrication had existed since the ancient times, but the most dominant form was the 'weaving' method which embodies the cross fabrication of vertical and horizontal threads using special weaving machines (looms). In addition, fabrication methods like knitting, felt, and lace were commonly practiced while intertwinement methods like twisting, braiding, and knotting techniques were frequently used for weaving strings and braid type textiles. In the past, people did not pay attention to strings and braids because they were classified as non-textiles, but, in this paper, we have expanded the scope of definition of textile to include strings and braids, and seek to conduct in-depth research on various different intertwinement of textiles. The adaptation of intertwinement method in arts and crafts enables limitless creative works reflecting the ever-changing taste and style of the creator. This creativity is further broadened by the fact that intertwinement methods encompass no set patterns and the subject and shape of its creation is as broad as its artistic pursuits. We can infer the knowledge of our ancestors, their aesthetic taste, and the pattern of life from these creations. In addition, these creations can provide comfort and improve the quality of life of modem people who are deeply deprived of sentimental and emotional solitude in the technological civilization of the 21stcentury. The main purpose of this paper is to examine traditional Korean arts and crafts made using the intertwinement methodology through the context of strings, braids, straw crafts and knotting method. Then it will conduct through research on the different materials, forms, characteristics, usage and other key notions based on the currently preserved records and relics to contribute to the research on traditional textiles and provide the foundations to the development of the Korean culture and cultural products, reflecting the true sole and aesthetics of traditional Korean textile crafts.

Korean traditional paper 'Hanji' made from the bark of the paper mulberry tree is a good handicraft material because of its high viscosity, durability, dyeability, toughness, flexibility, plasticity, and manipulability. Hanji has been used as a textile material such as cotton wool for protection and keeping us warm from cold weather. However, Hanji has many limitations, while other textile materials have many advantages of such as washability, being sunproof, and fast coloring. The purpose of this study is to review physical properties, formation ability, and dyeability of Hanji as a material of fashion accessary. The contents of this study are composed of 5 parts: 1. To introduce the necessities of this study, 2. To review a historical background of Hanji and to identify its physical characteristics as a fashion accessary material, 3. To review and to compare techniques such as bonding, quilting, knitting, creasing and holding, twisting, folding & braiding, paper pasting, coloring & cutting, and outwashing(?) in making Hanji fashion accessaries, 4. To review dyeing and finishing techniques to increase commercial value, 5. To identify the best fashion accessary materials made of Hanji. The most important characteristics of Hanji as a fashion accessary material are its toughness in a wet state, fast color fixing, and flexibility. Especially weaving and knitting are considered as the most desirable techniques to make fashion accessary products stronger and more practical.

This study used general carbon fibers(CF), which can be utilized for a low voltage cable screen, as well as metal-coated carbon fibers(MCF) to make cables and analyzed the properties of electromagnetic effectiveness. Both braid CF and MCF cables with 3,000 strands, 16 spindles, and braid density of 90% or over were adopted. The tape-type MCF specimens were spread into a tape(width: 15mm) using a hot melt to make a cable. The shield effectiveness was measured up to the 1GHz range in accordance with IEC 62153-4-6; braid shielded cables featured a superior shielding effect at 63dB than tape-type shielded cables. That was because the tape-type shielded cable has relatively more gaps and holes between carbon fibers than the braid type, resulting in a more inflow or emission of electromagnetic waves. In the case of braid cables, the characteristics of their electromagnetic waves were enhanced, with higher spindles and higher conductivity of carbon fibers. The shield effectiveness of the MCF shielded cable, however, was lower than that of tin-coated one.

Background: Stenting is an effective treatment option for tracheal collapse in dogs. Cross-braided tracheal stents are currently the norm in veterinary medicine, but cross-and-hook braided stents have recently been adopted in human medicine. We examined whether stents manufactured using this novel braiding technique provided additional advantages for the treatment of tracheal collapse in dogs. Objectives: To evaluate the outcomes of cross-and-hook braided stent implantation in the treatment of tracheal collapse in dogs. Methods: The medical records of 22 client-owned dogs that underwent luminal placement of cross-and-hook braided Fauna Stents for the treatment of tracheal collapse between January 2018 and July 2021 were examined and data on canine signalment, clinical signs, diagnostic test results, surgical outcomes, and postoperative complications were retrieved and analyzed statistically. Results: Twenty-six stents were surgically implanted, with 20 dogs (90.9%) receiving one stent and the remaining two (9.1%) receiving two or more stents. All dogs survived the procedure. The median survival time at a median follow-up of 990 days was 879 days. At the final follow-up examination, loss or mild improvement of cough was observed in all dogs. Conclusions: Compared with conventional lumen stents, the cross-and-hook braided Fauna Stent offered a higher survival rate and improved clinical symptoms in all patients. The results of this study suggest that the Fauna Stent may be a promising treatment option for dogs with tracheal collapse.
