A 5 day-old Warmblood foal was presented with a quarter crack due to the dam accidentally stepping on his left hind foot. Physical examination revealed the vertical crack included the coronary band of the medial side of the left hind hoof (quarter crack) with the lower pastern avulsion wound. Different from adult horses, the foot of the 5 day-old foal lacked adequate hoof wall thickness for stainless steel wire insertion and hoof size for a reinforcing fabric to be applied. Therefore, the authors decided to stabilize the edges of the cracked wall only by the polymethyl methacrylate (PMMA) composites without wiring and a reinforcing fabric application; and gluing a plastic shoe that was reshaped to protect the lower pastern and to spread pressure to other parts of the hoof when bearing weight. Disinfection and a supportive bandage were applied daily for 2 weeks. A month after the hoof crack accident, lameness had diminished. The quarter crack in this foal was treated successfully by the application of the composites three times with a reshaped gluing shoe, with approximately a month interval over the 4 months. After 4 months, it presented a successful functional recovery and needed no further treatment. When followed up 8 months after the accident, it revealed successful outcomes without hoof shape distortion and unbalanced hoof/limb growth.

This study aims to expand the scope of use for relics by applying the patterns and characteristics of embroidered fabric pieces, such as gold foil, excavated from the Mireuksa Temple Site in Iksan for fashion products. The artifact was a ra decorated with flower and vine patterns, embroidery using gold and red thread, and the unique stitching of Baekje. The pattern was reconstructed, as the embroidery was not well-preserved. This study used two types of gold-foil techniques: laser-cut and stone-stamp gold foil. Considering practicality, the gloss, toughness, custom production possibility, and design implementation were emphasized. The form of the laser-cut gold foil could be transformed; however, a recognition problem with the machine increased the thickness of the stitching. It was used for half-finished goods and commercial casual fashion. The stone-stamp gold foil was finely implemented, but the design was difficult to change. It was used for half-finished silk fabric for making hanbok po and lattice-patterned silk skirts. Applying the developed gold foil to suitable clothing can further enhance the effect.

To study the visual evaluation on the effect of ruffle's gather, the aesthetic evaluation on the gather's measurements and the image evaluation were performed. Evaluated fabrics were cotton, wool ani synthetic fiber, and 3 kinds of thickness for each fabric were selected. In order to seek for aesthetic gather's measurements, we performed the sensory test by the Rank Method on 5 kinds of gather's measurements(I.5 times, 1. 8times, 2times, 2.5 times, 3 times). For the image evaluation on the effect of the gather, we performed the sensory test by the Semantic Differential Method on the gather's measurements were got high score in the sensory test of the gather's measurements and analyzed by means of a Factor Analysis. The results were as follows. 1. Except 2 times of fabric $A_1$(thin cotton), the aesthetic gather's measurements of the ruffle were evaluted 2.5 times in cotton and synthetic fiber, and 2 times in wool. Generally the aesthetic gather's measurements of the ruffle were 2$\~$2.5 times. 2. The image characteristics of the ruffle were established the characteristics of the fabrics as factor 1, the characteristics of the atomosphere as factor 2 and the characteristics of the drape as factor 3. Therefore, we must consider the characteristics of the fabric, the atomosphere and the drape of the ruffle in production of the ruffle.

This study investigates the sound properties of fabric frictional sound (SPL, ${\Delta}L$, ${\Delta}f$) according to the film type of PTFE laminated vapor-permeable water-repellent fabrics in order to understand the relationship between SPL and the basic properties of fabrics such as layer, yarn type, and thickness of fiber. This study accesses their mechanical properties and determines how to control them to minimize SPL. Eight PTFE laminated water-repellent fabrics, composed of four different film types (A, B, C, D) and with two different fabrics, were used as test specimens. Frictional sounds generated at 1.21m/s were recorded by using a fabric sound generator and SPLs were analyzed through Fast Fourier Transformation (FFT). The mechanical properties of fabrics were measured by KES-FB. The SPL value was lowest at 74.4dB in film type A and highest as 85.5dB in type D. Based on ANOVA and post-hoc test, specimens were classified into less Loud Group (A, B) and Loud Group (C, D). It was shown that SPL was lower when 2 layer (instead of 3 layer), filament yarn than staple, and thin fiber than thick were used. In Group I, shearing properties (G, 2HG5), geometrical roughness (SMD), compressional properties (LC, RC) and weight (W) showed high correlation with SPL however, elongation (EM) and shear stiffness (G) did with SPL in Group II.

Indoor air quality is of increasing concern because it is closely related human health. An air handling unit (AHU) can be used to control the indoor air quality related to particulate matters and $CO_2$ as well as air conditioning such as temperature and humidity of indoor air. An electrostatic precipitator has a high collection efficiency and low pressure drop, however, ozone can possibly generate from its chargers, which is one of drawbacks to apply it for indoor air control. Here we compared four charging electrodes such as a $50{\mu}m$ tungsten wire, a $100{\mu}m$ tungsten wire, a $16{\mu}m$-thickness Al foil and a carbon fabric comprised of $5-10{\mu}m$ fibers. The carbon fabric electrode showed a superior particle collection efficiency and a lower ozone generation at a given power consumption compared to tungsten wires of 50, $100{\mu}m$ and an Al foil electrode. This low ozone generating, micro-sized electrode can be applied to the electrostatic precipitator in AHU for indoor air control.

In this study, printing was introduced to the common dip-dyeing method of persimmon juice dyeing so as to develop two different colored persimmon juice dyed fabrics with printings of 'jorangmal' patterns (a national monument) instead of producing a plain textile. Following are the results of a comparative study between the persimmon dyed fabric and undyed fabric, both with printings, in terms of its properties, and hand values. Cotton and rayon were chosen as samples and were compared separately. Firstly, the samples showed differences in terms of clarity and visual sensation depending on the presence of persimmon dye, even if the same pattern and color was used. Secondly, the air permeability of two samples improved after persimmon dyeing even though their thickness increased, and their moisture regain increased as well in all humidity conditions. Thirdly, protectiveness against UV increased in dyed samples, and sweat, sunlight, and compound colorfastness improved in printed dye-fabrics compared to plain dyed ones. Therefore, printing proved to be effective in preventing discoloration. Fourthly, tensile linearity and resilience, bending rigidity, compressive linearity and resilience, and shearing stiffness increased more in the dyed samples compared to undyed ones. However, shearing recovery decreased in both dyed fabrics. Fifthly, the result of its hand value showed that Koshi value increased in all samples than undyed ones, whereas Fukurami, Numeri, and Softosa values decreased. Incorporating printing in persimmon dyeing process could expect creative outcomes not only in today's diverse fashion but in areas of arts or crafts as well.

This study aimed to determine the physical properties of silk and nylon fabrics that are treated with persimmon juice in accordance with irradiation time of ultraviolet spectrum. Persimmon juice dyeing has the advantage of using the tannin component of the persimmon. Tannin plays an important role in inhibiting photodegradation of fibers or polymers. Among fibrous materials, silk and nylon are prone to deterioration by light. Hence, this study aimed to reduce these weaknesses of silk and nylon by applying persimmon juice treatment. We accordingly carried out investigation and experiments on ultraviolet irradiation, and physical characteristics of treated fabrics. The persimmon juice treatment process led to increased weight and thickness. In addition, the air permeability of silk fabric was increased, as compared to the control specimen; whereas, that of nylon fabric was decreased. Both drape stiffness and flex stiffness of silk and nylon tended to be high in textiles processed with persimmon juice treatment, as compared to the control textile. Peak load and elongation at peak load of untreated samples clearly decreased in both silk and nylon fabrics with the increase of ultraviolet irradiation time, while those of persimmon juice treated samples increased. Furthermore, ultraviolet blocking ratio measurement indicated that the fabric specimens treated with persimmon juice blocked U.V. spectrum better than the control specimen.

We describe fabrication of superhydrophobic surface on non-woven fabric (NWF) having nano-hairy structures and a hydrophobic surface coating. Oxygen plasma was irradiated on NWF for nano-texuring and a precursor of HMDSO (Hexamethydisiloxane) was introduced as a surface chemical modification for obtaining superhydrophobicity using 13.56 MHz radio frequency-Plasma Enhanced Chemical Vapor Deposition (rf-PECVD). O2 plasma treatment time was varied from 1 min to 60 min at a bias voltage of 400V, which fabricated pillar-like structures with diameter of 30 nm and height of 150 nm on NWF. Subsequently, hydrophobic coating using hexamethyldisiloxane vapor was deposited with 10 nm thickness on NWF substrate at a bias voltage of 400 V. We evaluate superhydrophobicity of the modified NWF with sessile drop using goniometer and high speed camera, in which aspect ratio of nanohairy structures, contact angle and contact angle hysteresis of the surfaces were measured. With the increase of aspect ratio, the wetting angle increased from $103^{\circ}$ to $163^{\circ}$, and the contact angle hysteresis decreased dramatically below $5^{\circ}$. In addition, we had conducted experiment for nucleation and condensation of water via E-SEM. During increasing vapor pressure inside E-SEM from 3.7 Torr to over 6 Torr which is beyond saturation point at $2^{\circ}C$, we observed condensation of water droplet on the superhydropobic NWF. While the condensation of water on oxygen plasma treated NWF (superhydrophilic) occurred easily and rapidly, superhydrophobic NWF which was fabricated by oxygen and HMDSO was hardly wet even under supersaturation condition. From the result of wetting experiment and water condensation via E-SEM, it is confirmed that superhydrophobic NWF shows the grate water repellent abilities.
