Recently more than ever, interest in Korean tradition has been on the increase, with an active movement to follow tradition. There are various merits for expression with the use of Korean paper as a clothing material. The purpose of this study was to assess the aesthetic characteristics of men's shirts fashioned using Korean paper (Hanji). The following conclusions were obtained from an analysis of the aesthetic characteristics of Hanji shirts. First, Hanji has a peculiar texture, with natural characteristics due to the direct use of naturally handcrafted materials. Hanji shirts have the natural beauty of pure Hanji, without artificial treatment or other subsidiary materials, with the exception of thread. Secondly, Hanji shirts with decorative details and trimmings, such as frills, pin tuck, embroidery and spangles, express an ornamental beauty. Thirdly, Hanji shirts with frills or a fringe have real movement when worn and spangles give the illusion of movement due to changes in color or twinkling caused by light giving the beauty of rhythmical motion. Fourthly, Hanji shirts produced using the application of various techniques, such as crumple, painting and dying, express artistic beauty. Fifthly, Hanji shirts can express traditional beauty, even if created whit modem designs, but using traditional materials.

Fabrics dyed with artemisia extract have quite natural and elegant tones of color. This study purposed to find the best one for dyeing among artemisia collected in the four seasons in order to develop a more efficient method of dyeing with artemisia. As for the method of research, the researcher dyed wool fabric and silk fabric with artemisia, and measured dyeability according to the number of repeats of dyeing, coloration by post-mordant, color fastness to washing, color fastness to dry cleaning and color fastness to light. The results are as follows. 1. In dyeing with artemisia, dyeability was improved as the number of repeat of dying increased, and it was higher in wool fabric than in silk fabric. 2. Among artemisia collected in the four seasons, autumn artemisia had dyeability much inferior to that of artemisia from the other seasons, and winter artemisia had the best dyeability. 3. According to the result of treating fabric with post-mordant, the dyeability was improved significantly, and coloration was most remarkable when copper and iron mordant were used. 4. The color fastness to washing and color fastness to dry cleaning of fabric mordanted with artemisia were as high as grade 4-5 and grade 5 respectively. The color fastness to light was highest in winter artemisia as grade 4.

We studied on the decoloring efficiency of a dying and finishing industrial wastewater containing reactive dyes in the ozone treatment system. The wastewater containing reactive dyes improved the decolorization by the ozone oxidation. In order to determine the optical conditions for ozonation, various operation factors such as initial wastewater concentrations, pH, temperature, and ozone dose were evaluated. Ozone utilization rate was improved in general with the increase of initial concentration of wastewater. And the decolorization speed or reactive dyes was more decreased in deep color of blue series than in light color such as yellow series. The colorization of wastewater containing reactive dyes was changed step through midle color depending upon increasing of ozone treated time. The efficiency of decolorization for wastewater was improved with the pH increased and the temperature of ozone treatment system decreased.

Effects of group breeding of herons on pine community were studied at Pomaeri, in Yangyang, Kangwon Province, Korea. This site has been protected as a Natural Monument (No. 229) since 1970. Herons have used this habitat as a breeding site from] anuary to October every year. In 1995, more than 500 herons were observed in this habitat. Many big pine trees are dying or already dead due to group inhabitation of herons, and no pine saplings were found at forest floor in this habitat. Nutrient contents of soil in this habitat were much higher than those in control plot. This must be due to the addition of feces from herons and of thin twigs and other organic materials from the canopy and bird nests. Species composition of herb layer in this habitat was quite different from that in control plot. Breeding site was dominated by Humulus japonicus. Persiearia perJohata, Persicaria thunbergii. and Commelina communis. which are indicator species of soil eutrophication.

The purpose of this paper is to examine the street fashion, which is influenced by the youth culture in 1960s. Youth culture is the youth subculture which appeared multiform in the 1960s. It tried to create a new culture by subverting the ruling class culture with their combative life style and peculiar appearance which are distinguished from mother culture. Youth cultures as youth subculture are symbolically expressed in their style which had strong characteristics of sub-fashion and anti-fashion, and which are different from mother fashion in shape. Therefore youth subculture fashion had an effect on street fashion in the 60s. The influence that the youth culture fashion had had on the street fashion is summarized as follows: Beats fashion was intelligency look on black dress, black polo-neck shirts, black trousers, black glasses and heavy black eyeliner. Mods fashion was neat style on Edwardian suit with narrow trousers, pointer-toeshoes and smooth croped hair. Folkis fashion was ethnic look, middle east asian look, peasant look, Indian style, south america look, gypsy style, natural materials, natural dying, tie-dye, beads and hand made ornaments. Rockers fashion was violence appearance categorized 'blue collar' on black leather jacket decorated with metal studs and hand-painted insignia, blue jeans and boots for motor bike. Swinging London & the Psychedelics fashion was blend mods look with pschedelic color and motive pattern. Hippie fashion was intermix pschedelic and natural or ethnic style. It was appear to be a meaningless, unpredictable assortment of diverse items and style. Faded and tattered jeans, army jackets, vintage hat, beads, embroidered headband, white sheets, diverse theatrical costumes, sandals or bare feet, granny dress, peasant blouse, blanket cape, tie-dye T-shirts and long hair. Greasers fashion was adorned black leather jacket with chains, fringing, badges, insignia and sleeves had been crudely ripped off. They came to be known wore jeans so soaked with oil. Skinheads fashion was aggressive working class identity with donkey jacket, jeans rolled up, collarless union shirts, heavy boots, braces and hair cropped short.

Cancer cells undergo the epithelial-mesenchymal transition (EMT) and show unique oncogenic metabolic phenotypes such as the glycolytic switch (Warburg effect) which are important for tumor development and progression. The EMT is a critical process for tumor invasion and metastasis. High-mobility group box 1 (HMGB1) is a chromatin-associated nuclear protein, but it acts as a damage-associated molecular pattern molecule when released from dying cells and immune cells. HMGB1 induces the EMT, as well as invasion and metastasis, thereby contributing to tumor progression. Here, we show that HMGB1 induced the EMT by activating Snail. In addition, the HMGB1/Snail cascade was found induce a glycolytic switch. HMGB1 also suppressed mitochondrial respiration and cytochrome c oxidase (COX) activity by a Snail-dependent reduction in the expression of the COX subunits COXVIIa and COXVIIc. HMGB1 also upregulated the expression of several key glycolytic enzymes, including hexokinase 2 (HK2), phosphofructokinase-2/fructose-2,6-bisphosphatase 2 (PFKFB2), and phosphoglycerate mutase 1 (PGAM1), in a Snail-dependent manner. However, HMGB1 was found to regulate some other glycolytic enzymes including lactate dehydrogenases A and B (LDHA and LDHB), glucose transporter 1 (GLUT1), and monocarboxylate transporters 1 and 4 (MCT1 and 4) in a Snail-independent manner. Transfection with short hairpin RNAs against HK2, PFKFB2, and PGAM1 prevented the HMGB1-induced EMT, indicating that glycolysis is associated with HMGB1-induced EMT. These findings demonstrate that HMGB1 signaling induces the EMT, glycolytic switch, and mitochondrial repression via Snail activation.

Loess was selected as one of the natural dyes and dye solution was extracted from it. With the dyes extracted from loess, the sample fabrics were dyed at 10, 20, and 30 minutes and then $CuSO_4$ was used to treat the dyed fabrics on the concentration of 3%, and 5%. Color difference and colorfastness of the sample fabrics with dyeing time and concentration of post-mordanted agent were analysed. The results were as follows: 1. Effective dying time was 20 minutes since any more dye up-take to the fabrics did not occur after that time. 2. There was distinctive dyeing effect according to whether post-mordanted method was done or not, but there was little effect between post-mordanted concentration of 3% and 5%. 3. There was no effect of the colorfastness on the post-mordanted concentration. The abrasion and laundering colorfastness of post-mordanted fabric samples was better than those of no post-mordanted fabric samples and the light colorfastness of the fabric samples was good regardless of post-mordanted method.

Yellow, one of the five direction colors, is a prevailing color in artificial dyeing. The color has implied and symbolized wealth and power since ancient times. Yellow has been extracted mainly from flowers. Shapes, colors and scents of flowers not only have enriched emotional mentality, but have also been used for medicinal herbs, and dyestuff since the very old days. Coloring matter from flowers is very beautiful, and it has been used for dyeing textiles. Textile dyeing have formed a color culture and developed a dyeing culture since ancient times. Flowers include a variety of color matters, and can be easily obtained around us. Therefore, flowers have been a widespread natural dyestuff. It is well known that beautiful colors can be extracted from flowers, which are eco-friendly and non-polluting. In addition, flowers are easily provided. In this study, yellow wild flowers were selected as subjects. Seven flowers with color matters distiguishable through the naked eye were used: Korean forsythia, golden-wave, Mongolian dandelion, sunflower, conflower, chelidonium and chrysanthemum. Coloring matters were extracted from the seven flowers, which have been used to create a variety of colors through various dyestuffs; and the colors have been analyzed and presented. Dyeing and coloring matters were tested and analyzed, and several types of dyestuff had also been scientifically measured after treatment.
