Reactive dyes waste water, a toxic and refractory pollutant, was treated by an electrochemical method using $Ti/IrO_2$ as anode and Stainless Steel 316 as cathode. In this technique, sodium chloride as an electrolyte was added. A number of experiments were run in a batch system. Artificial samples (reactive blue 19, red 195, yellow 145) were used. Operation parameters, such as supporting electrolyte concentration, current density, pH and sample concentration have been investigated for their influences on COD and color removal efficiencies during electrolysis. After 5 and 90 minites of eletrolysis, color was reduced by 51.5% and 98.9% respectively. Under the condition of current density $10A/dm^2$, NaCl concentration 12mg/l and pH 3, 62.9% of $COD_{Cr}$ was removed after electrolysis for 90 minites. The optimum condition of color removal and COD reduction in this work was found to be the following : pH 3, sodium chloride concentration 20g/l, current density $10A/dm^2$. As a result, we confirmed to be effective to color removal and reduction of refractory organic material.
Objectives: This study aimed to analyze the mineral composition of naturally- and artificially-produced caries-affected root dentin and to determine the elemental incorporation of resin-modified glass ionomer (RMGI) into the demineralized dentin. Materials and Methods: Box-formed cavities were prepared on buccal and lingual root surfaces of sound human premolars (n = 15). One cavity was exposed to a microbial caries model using a strain of Streptococcus mutans. The other cavity was subjected to a chemical model under pH cycling. Premolars and molars with root surface caries were used as a natural caries model (n = 15). Outer caries lesion was removed using a carbide bur and a hand excavator under a dyeing technique and restored with RMGI (FujiII LC, GC Corp.). The weight percentages of calcium (Ca), phosphate (P), and strontium (Sr) and the widths of demineralized dentin were determined by electron probe microanalysis and compared among the groups using ANOVA and Tukey test (p < 0.05). Results: There was a pattern of demineralization in all models, as visualized with scanning electron microscopy. Artificial models induced greater losses of Ca and P and larger widths of demineralized dentin than did a natural caries model (p < 0.05). Sr was diffused into the demineralized dentin layer from RMGI. Conclusions: Both microbial and chemical caries models produced similar patterns of mineral composition on the caries-affected dentin. However, the artificial lesions had a relatively larger extent of demineralization than did the natural lesions. RMGI was incorporated into the superficial layer of the caries-affected dentin.
To analyze the characteristics of Orientalism which is expressed in the fashion of the 1990's this study was examined according to three aspects such as form textiles and pattern and the aspects was considered with regard to Chinese Indian Japanese Korean, Southeas Asian and North African style. 1. In form Orientalism which is influenced by latest other fashion trend; Naturalism and Minimalism is expressed as a comfortable casual style which simplifies the way of wearing and mixes the characteristic elements of folk costume with western costume. The way of layerd wearing like knotting wrapping draping and the symbolic from which is inspired by the unique are of each country are shown. 2. In textiles Chinese Japanese and Indian silk as well as Southeast Asian and North African cotton show a splendid oriental impression using vivid color. On the other hand the linens of Korea like hemp and ramie emphasize natural characteristics and show a simple and unartificial oriental beauty. But in the use of material and color it shows a remarkable tendency to break the preconceived idea by coordinating a luxurious silk with a practical denim or harmonizing technical new-masterials with traditional materials. 3. In pattern the decorative elements of Orientalism such as a traditional pattern skills to dye embroidery and other decorations are emphasized on the form of western costume. The sketchy patterns of Chinese Korean and Japanese styles which include the pattern of a flower a bamboo and a butterfly are expressed using embroidery or textile printing. The geometrical seriate patterns of Southeast Asian and North African styles use traditional dyeing methods like Batik. Also the Indian technique of decoration like Mirro Work satisfies handcrafted royalty and feminine romantic taste in modern minimal fashion. The Orientalism expressed in the fashion of 1990's emphasizes the characteristics of people wearing colthing which break the preconceived idea by simplifying the form harmonizing differences between oriental and western cultures and mixing the elements of traditional costumes among countries. Most of all. Ethno using geonmetrical seriate pattern and technical new metal material and Romantic Ethnic using flower embroidery precious stones and beads are appearing as a distinctinve feature.

The quantification of dry season evaporation in regions, where the magnitude of dry season flows is key to the regional water supply, is essential for good water management. Also, tree transpiration has a significant role in the water balance of a catchment whenever it is tree populated, especially in water limited environments. Such is the case in the Middle Mountains of Nepal where dry season flows play a significant role in downstream water provisioning and their proper functioning is key to the welfare of millions of people. This research seeks to study the transpiration of a pine forest stand in the Jikhu Khola Watershed in the Middle Mountains of Nepal. To the author's knowledge, no single study has been made so far to estimate the dry season evaporation from the planted forest stand in the Middle Mountains of Nepal. The study was carried out in planted pine forest embedded within the Jikhu Khola Catchment. Field campaigns of sap flow measurements were carried out from September, 2010 to February, 2011 in the selected plot of 15*15m dimension, to characterize dry season evaporation. This was done by measuring sap fluxes and sapwood areas over the six trees of different Diameter at Breast Height (DBH) classes. The sap flux was assessed using Granier's thermal dissipation probe (TDP) technique while sapwood area was determined using several incremental core(s) taken with a Pressler borer and immediately dyeing with methyl orange for estimating the actual depth of sapwood area. Transpiration of the plot was estimated by considering the contribution of each tree class. For this purpose, sap flux density, sapwood area and the proportion of total canopy area were determined for each tree class of the selected plot. From these data, hourly and diurnal transpiration rates for the plot were calculated for experimental period. Finally, Cienciala model was parameterized using the data recorded by the ADAS and other terrain data collected in the field. The calibrated model allowed the extrapolation of Sap flux density (v) over a six month period, from September 2010 to February 2011. The model given sap flux density was validated with the measured sap flux density from Grainier method.
This study aims to rediscover the industrial value of a borderless service in the hyper-connected era by producing fashion content at the forefront of the cultural industry as XR content and contributing to developing fashion content for edutech. The research method employed design aesthetic theory, while the empirical proposal utilized scientific knowledge information to build a framework for 3D convergence content. The characteristics of fashion content exhibitions that apply the neumorphism technique are as follows: The first is a virtual space that produces clothing culture by type. Africa, where dyeing and crafts are developed, selects a product-oriented exhibition type; Asia, where weaving and textiles are excellent, selects a random movement type; and Europe, where the evolution of clothing design over time is evident, selects a guided movement type to create a three-dimensional fashion edutech. The goal was to produce content. The second is creative reproducibility, which combines a new fashion design that embraces the aura of the original with a trendy sense. The realistic folk costume style of the original allowed for its implementation in the AR exhibition space using historical traditional style techniques such as weaving and textiles. The third is building organic, modular content. By designing and then saving/editing/arranging the basic VP zone for each style, learners and instructors can freely edit the content for each fashion class topic and create various presentations to ensure that it functions as non-face-to-face edutech content around the world.
This study examines the stage costumes of the creative musical 'Hyecho', which was performed six times in the Chung Ang Art Center hosted by Chung-Ang University's performance & media agency from December 20 to 22 in 2006. The stage costumes were made based on these basic design elements of stage costumes that were dyed : line, silhouette, material, and color. First, the creative musical 'Hyecho' presents a new form of fusion theatre, which blends Korean traditional music and dance with videos. Thereby, the musical has opened a new phase in Korea's creative performing arts. Second, in musical performances that combines dance and songs, stage costumes should be made not only to attract the audience's eyes, but also not to interrupt actors' vocalizations and movements by taking their physical features into account. Also, costumes should be made in consideration of their relationships with visual elements, including stage settings and lighting. Third, the musical features fusion-style stage costumes, which combines Hanbok, the Korean traditional costume, and Indian traditional costumes with modern costumes. For the line and silhouette, costumes show the beauty of curves through the curves of Hanbok and India's traditional costumes and also through irregular pleats of pants. Also, by using cotton materials, which is easy to dye and not readily deformed, costumes feature colors that are found in nature through a gradation dyeing technique. In doing so, it offers visual amusement to the audience by making stage costumes look like a beautiful painting. Fourth, the stage costumes of the chorus feature costumes that use lining and pleated skirts using belts, and various accessories, including necklaces that use strings in order to express evil spirits. Since there is not much time to change costumes during a performance, using such items are helpful to show the unique characteristics of actors effectively during the limited time. Also, coordinating with the lighting director allows the costume designer to make better costumes for the chorus and make the performance more dramatic. Finally, it was not necessary to wash the costumes of the chorus of the fusion musical Hyecho 2006 since it was performed only six times. However, when using dyed costumes for the long-term performance, it might cause problems such as bleaching that result from the washing of costumes and low durability that can result in the deformation of costumes. As performing arts are made in various forms and are diversified, it is needed for stage costumes to change accordingly through new attempts and various ways of expression.
