Dye wastewater generally contains strong color and non-biodegradable materials. Therefore, the conventional wastewater treatment plant can hardly meet the regulation of wastewater effluent water. In this study, a pilot plant of the conventional process followed by advanced oxidation process (AOP), was set up to treat the dying wastewater. The treatment efficiencies on the various candidate processes, such as ozone alone, UV alone, ozone/UV, $ozone/H_2O_2$, $H_2O_2/UV$ and $ozone/UV/H_2O_2$, were investigated in the various ozone and $H_2O_2$ doses. As the results, the $ozone/H_2O_2$ process, among the tested processes, showed the highest efficiency for removing color and $COD_{Cr}$. For color removal, the ozone alone process was enough without combining UV or $H_2O_2$. No significantly enhanced efficiency for removing color and $COD_{Cr}$ by UV irradiation was observed because of the very low transmittance of UV light in dye wastewater.

The purpose of this study was to determine the effects of flower decorations on job stress and stress copying style of police officers. Flower decorations were done in the form of "one-table one-flower", in which flowers were placed on each desk in the office space. By analyzing color psychology, we first identified the symbolism of color, and selected the cut flowers in the same color. We selected six types of flowers in six colors: red, orange, yellow, green, blue and purple. Each Monday morning, the flower decorations were delivered to the police station. We selected 50 subjects who wanted to keep flowers on their desks every week as the experimental group and 44 subjects who only wanted to participated in the assessment as the control group. Before and after the program, we examined the mean difference between the control group and experimental group. After six sessions of the program, there was a significant difference in job stress (p < .001) and stress copying style (p = .049) of the experimental group compared to the control group. Therefore, this study proved that having flower decorations in an office space is effective for the psychological stability of police officers that are highly stressed, due to sensory stimulations from the colors and scents of flowers as well as mutual interaction as they take care of the flowers.

This study aims to identify how Korean women's traditional costume, Hanbok, has changed according to the times in terms of color coordination of Jeogori and Chima. Photos had been taken at wedding places and streets at 5 major cities(Seoul, Pusan, Kwangju, Daejon, Jeju) at two weekends of each season in 1999, 2001, and 2003. Total 1617 photos were used as final data. Data were analyzed by hue coordination and value level. Hue coordination exist in one-color and two-color coordination. In one-color coordination, red color(R & RP) was the most frequently used and blue green(BG) was the next, and the least was blue purple(BP) for each year. In value scale, high level was the most frequent and followed by middle level and low level. Pink was the most preferred color for one-color coordination. In two-color coordination, white and blue were widely used for Jeogori and red and blue far chima for each year, which seemed to be the basic color coordination for Jeogori and Chima. While there was a certain basic color coordination types across year, but a few new color coordination appeared each year and maintained as popular color coordination for one or two year.

In the current fashion design, the 'environmental friendliness' affects the practically and conceptuality in all industry and culture sectors. This study seeks to examine specific design elements as the content of design factors in environment oriented fashion. The subjects of this paper are studied through scholarly journals that are confined to those from 1990 (when naturalism and ecology trends started to be in fashion) to February 2009. This study used 'Naturalism', 'Green', 'Environment-friendly', 'Eco', 'Sustainable', 'Well-being' and 'Lohas' as key words for the literature search. The analysis is performed through a content analysis and the unit of analysis is based upon the adjectives, nouns, and phrases related to the content of the design elements such as line, color, and textiles. In the results, more expression is natural, minimal, transformable, and sportive style in line, YR, white, soft, pale, and dull tone in color. The prominent textiles and texture were natural fabrics, environment-friendly fabrics, recycled fabrics, natural dyeing, functional finishes, rustic surfaces, flexibility, and extensibility. The results of this paper will help in future fashion design product development for environment-friendly fashion brands.

Recently, autonomous robots which can achieve the complex tasks have been required with the advance of robotics. Advanced robot vision for recognition is necessary for the realization of such robots. In this paper, we propose a method to recognize an object in the actual environment. We assume that a 3D-object model used in our proposal method is the voxel data. Its inside is full up and its surface has color information. We also define the word "recognition" as the estimation of a target object's condition. This condition means the posture and the position of a target object in the actual environment. The proposal method consists of three steps. In Step 1, we extract features from the 3D-object model. In Step 2, we estimate the position of the target object. At last, we estimate the posture of the target object in Step 3. And we experiment in the actual environment. We also confirm the performance of our proposal method from results.

To suggest a more efficient way of delivering information for process control under computerized environment, population stereotypes of colors were tested with 57 Korean subjects. The subjects were asked to associate 11 colors salient at electronic video displays with 55 pairs of adjectives that might be used when they explain the current state of process. The levels of association were evaluated with semantic differential methods by 7 point scales. Based on the multivariate analyses, the 55 pairs of adjectives were grouped into three distinct dimensions. The emotional maps of the 11 colors with respect to each dimension were presented. The Quantitative relationships between the colors and subjective impressions were also calculated by quantification theory I. On the basis of these color associations, it was suggested a general guideline for color coding when delivering process information
