Jacqueline Kennedy Onassis (July 28, 1929 - May 19, 1994) was served as First Lady of the United States in the early 1960s. Her fashion styles are analyzed into the elements of designs, and the features of Jackie look are assorted. A variety of sources about women's suits for the 21st century are suggested in the research. Jackie's taste in fashion, her fashion image are searched. In addition, after Jackie, other nine fashionable First Ladies' evening dresses are compared to Jackie's dresses so as to see if there are similarities between their styles. Based on this data, the typical First Lady's look is classifiable. The purpose of this study is to furnish the industry with basic information which helps create high value fashion design. Most of Jackie's evening dresses had the straight - sheath silhouettes, and the round or bateau necklines without collars. Pale tones like white predominated in her dresses, and patternless colorful silk, silky and bright texture of cloth was used for the dresses. Elegance and classic represented her image. Design features of Jackie look are the straight silhouette, the simple line excluded adornments, and the fine quality of cloth. There has been little change in other nine First Ladies' evening dresses since Jackie. They weren't influenced by the vogue at that time, but they kept the style the way Jackie did. Jackie style is the beginning of the typical first lady look, that is.

The objective of this study is to develop eco-friendly, functional towel material utilizing cotton-Modal-chitosan blended(C-M-CH) yarn and natural dyeing with mugwort colorants. Dyeing properties of towels with mugwort colorants were studied by investigating the effect of dyeing conditions including concentration of mugwort colorants, dyeing temperature, and dyeing time, and the effects of mordants on dye uptakes were investigated. The C-M-CH towel showed better dye uptake than 100% cotton towel with mugwort colorants. The shade of towels got darker and red-yellowish tint increased by mordanting. Comparing with 100% cotton towel, the colorfastness of dyed C-M-CH towel was satisfactory showing above 3 grade which is the lowest grade to washing fastness. The antibacterial activity against Staphylococcus aureus and deodorization performance of towels were excellent and improved by dyeing with mugwort colorants. From the results obtained, it is concluded that the cotton-Modal-chitosan blended towel dyed with mugwort colorants can be used practically for an eco-friendly and multi-functional towel materials with excellent absorbance and drying properties.

In dyeing cotton fabric with the Indigo Pulverata Levis, this research examined the effect of the sodium dithionite($Na_2S_2O_4$). For the separation of the Indigo-calcium hydroxide complex in the alkaline solution of the Indigo Pulverata Levis, the reduction with the $Na_2S_2O_4$ at $25^{\circ}C$ was more effective than the solution boiling. The concentration of Indigo in the cotton fabric increased with the increase of Indigo Pulverata Levis, but the concentration of indirubin did not increase particularly. The optimum temperature for the reduction was $60^{\circ}C$, and K/S value of dyed fabric decreased at over $60^{\circ}C$. The concentration of indigo and indirubin in the cotton fabric decreased as $Na_2S_2O_4$ concentration increased. In treating cotton fabric dyed with the Indigo Pulverata Levis by the $Na_2S_2O_4$, the concentration of indirubin decreased and the surface color of dyed cotton changed from purple blue to blue while the treatment temperature was getting higher.

Currently smart textile market is rapidly expanding and the demand is increasing integration of an electronic fiber circuit. The garments are an attractive platform for wearable device. This is one of the integration techniques, which consists of is the selective introduction of conductive yarns into the fabric through knitting, weaving or embroidering. The aim of this work is to develop a golf bend driven prototype design for an attachable Arduino that can be used to assess elbow motion. The process begins with the development of a wearable device technique that uses conductive yarn and flex sensor for measurement of elbow bending movements. Also this paper describes and discusses resistance value of zigzag embroidery of the conductive yarns on the tensile properties of the fabrics. Furthermore, by forming a circuit using an Arduino and flex sensor the prototype was created with an assistance band for golf posture training. This study provides valuable information to those interested in the future directions of the smart fashion industry.

Microalgal biofuel production from wastewater has economic and environmental advantages. This article investigates the lipid production from high chemical oxygen demand (COD) bioethanol wastewater without dilution or additional nutrients, using a newly isolated heterotrophic microalga, Chlorella vulgaris LAM-Q. To enhance lipid accumulation, the combined effects of important operational parameters were studied via response surface methodology. The optimal conditions were found to be temperature of $22.8^{\circ}C$, initial pH of 6.7, and inoculum density of $1.2{\times}10^8cells/ml$. Under these conditions, the lipid productivity reached 195.96 mg/l/d, which was markedly higher than previously reported values in similar systems. According to the fatty acid composition, the obtained lipids were suitable feedstock for biodiesel production. Meanwhile, 61.40% of COD, 51.24% of total nitrogen, and 58.76% of total phosphorus were removed from the bioethanol wastewater during microalgal growth. In addition, 19.17% of the energy contained in the wastewater was transferred to the microalgal biomass in the fermentation process. These findings suggest that C. vulgaris LAM-Q can efficiently produce lipids from high-concentration bioethanol wastewater, and simultaneously performs wastewater treatment.

The purpose of this study was to compare two analytical methods classifying foot shape. The methods compared were cluster analysis method and foot index analysis method. This study defined the women's foot shape by these methods. 39 foot measurements which were automatically collected using the three dimensional foot scanner were analyzed. 203 Korean women in age 20s were participated in the anthropometric survey. Their foot shapes were classified into 5 foot types by cluster analysis: short & slim shape, flat shape, short & slender shape with slightly distorted toe, long and big shape, and short & wide shape. The foot measurements were also analyzed by the ratio of foot width and length. Five foot types that were classified by cluster analysis and three foot types that were classified by the foot index were compared. The comparison shows that cluster analysis precisely defined foot shapes. It was suggested that made-to-measure shoes making industry may adopt the foot shape analysis method utilizing cluster analysis.

The effluent discharge standards of industrial wastewater has become more stringent since 2003. Many industrial wastewater treatment plants has been upgraded to advanced treatment facilities. There are high concentrations of nitrate(>200 mg/L) and ammonium(>50 mg/L) nitrogen in the acrylic fiber wastewater of H textile Co. Wastewater from acrylic fiber industry containing acrylonitrile, which may affect the subsequent biological treatment process. Manufacturing of acrylic fiber also produces shock loadings. Excessive acrylonitrile and polymer debris produced in the polymerization process was screened, coagulated with CaO and settled down. A preaeration system was added to treat this high pH effluent to remove volatile organic compound and ammonia nitrogen by the air stripping effect. it was found that nitrification rate was not sufficient in the Anoxic/Oxic(AO) process. One denitrification tank was converted to nitrification reactor to extend HRT of nitrification. Nitrification rate of ammonia nitrogen was promoted from 32% to 67% by this modification and effluent nitrogen concentration was well satisfied with the effluent standards since then.

A Staphylococcus sp. EY-3 with the capability of decolorizing Congo Red was isolated from soil at an effluent treatment plant of a textile and dyeing industry. This strain was able to almost completely decolorize a high concentration of Congo Red in 48 h under aerobic conditions. Optimal color removal (more than 96%) was achieved at 30- 40oC, and no noticeable effects of different pH values (5.5- 8.0) on decolorization were observed. This strain also exhibited a remarkable decolorization capability against azo dyes under aerobic conditions, even at a high concentration (dyes 1 g/l) of dye. The metabolic product of Congo Red degradation by this strain was identified by gas chromatography with mass selective detection (GC/MSD) to be an amine derivative benzidine.
