This study examined the wastewater at a livestock farm, and found that the dairy wastewater from the milking parlor had a lower concentration than the piggery wastewater, and that it was produced at a rate under 1.3 ㎥/day in a single farmhouse. The amount of dairy wastewater was determined based on the performance of the milking machine, the maintenance method of the milking parlor, and the amount of milk production allocated for each farmhouse, not by the area. The results confirmed that both dairy wastewater treatment processes, specifically those using Hanged Bio-Compactor (HBC) and Sequencing Batch Reactor (SBR), can fully satisfy the water quality standards of discharge. The dairy wastewater has a lower amount and concentration than piggery wastewater, meaning it is less valuable as liquid fertilizer, but it can be easily degraded using the conventional activated sludge process in a public sewage treatment plant. Therefore, discharging the dairy wastewater after individual treatment was expected to be a more reasonable method than consigning it to the centralized wastewater treatment plant. The effluent after the SBR process showed a lower degree of color than the HBC effluent, which was attributed to biological adsorption. In the case of the milking parlor in the livestock farm, the concentrations of the effluents obtained after HBC and SBR treatments both satisfied water quality standards for the discharge of public livestock wastewater treatment plants at 99% confidence intervals, and the concentrations of total nitrogen and phosphorous in untreated wastewater were even lower than the water quality standards of discharge. Therefore, we need to discuss strengthening the water quality standards to reduce environmental pollution.

Since long ago, "The Discourse of Confucius" has been considered as one of the must-read classical literatures in the world of art. The term Huì-shì-$h{\grave{o}}u-s{\grave{u}}$ (繪事後素) in this literature is not only known by the painter but is also known to anyone who discuss about pictures. However, there is a great diversity of interpretation between its meaning of "drawing a picture is done when its basis is ready" or "drawing a picture is done later when completed with white color". The method of drawing does not change much with time. Scholars usually consider professional paintings conventional and don't understand well the white characteristics of the painting technique. In any case, it is basic to deal with the basis before drawing but completing the picture, finishing with white is not so common. Paintings from ancient times are not so different from today's silk pictures. Because Huì-shì-$h{\grave{o}}u-s{\grave{u}}$(繪事後素) fostered the attainments being the basis of life and the artistic sense, it remains as the aesthetics to many artists. The interpretation of Huì-shì-$h{\grave{o}}u-s{\grave{u}}$(繪事後素) is related to the change with time in 'The theory of courtesy(禮論)' but this study focused purely from the artistic point of view.

Image dehazing is an ill-posed problem which is far from being solved. Traditional image dehazing methods often yield mediocre effects and possess substandard processing speed, while modern deep learning methods perform best only in certain datasets. The haze removal effect when processed by said methods is unsatisfactory, meaning the generalization performance fails to meet the requirements. Concurrently, due to the limited processing speed, most dehazing algorithms cannot be employed in the industry. To alleviate said problems, a lightweight fast dehazing network based on a multiple scale-patch framework (MSP) is proposed in the present paper. Firstly, the multi-scale structure is employed as the backbone network and the multi-patch structure as the supplementary network. Dehazing through a single network causes problems, such as loss of object details and color in some image areas, the multi-patch structure was employed for MSP as an information supplement. In the algorithm image processing module, the image is segmented up and down for processed separately. Secondly, MSP generates a clear dehazing effect and significant robustness when targeting real-world homogeneous and nonhomogeneous hazy maps and different datasets. Compared with existing dehazing methods, MSP demonstrated a fast inference speed and the feasibility of real-time processing. The overall size and model parameters of the entire dehazing model are 20.75M and 6.8M, and the processing time for the single image is 0.026s. Experiments on NTIRE 2018 and NTIRE 2020 demonstrate that MSP can achieve superior performance among the state-of-the-art methods, such as PSNR, SSIM, LPIPS, and individual subjective evaluation.

Recently, due to the development of interactive media, Interactive Typography, which explores user input and interaction is under development. Unlike traditional typography which has a fixed nature, the flexible and fluid nature of Interactive Typography and Interactive System, enables diverse results. In this study, I have developed an Interactive Typography art piece based on theoretical research. By reviewing books, papers and articles, I have tried to define the meaning and characteristics of Interactive Typography. In understanding the concept of Interactive System, I have borrowed the concept of mathematical function. Based on the research, I have designed and developed an Interactive Typography piece, 'Interactive floral type' by using Adobe flash action script. This piece explores the beautiful shape of each alphabet letters and transforms individual character into a 'flower' shape through user's mouse and keyboard input. Depending on the input the size, color, and layout and motion of text changes in real time to change the letters into beautiful flowers.

This study aims to develop a mechanic embroidery bag design that reflects the symbolic image of Korean independence activists who sacrificed for the country so that today's Korea can exist. As a research method, the theoretical consideration and image collection of independence activists were conducted through a literature review and visits to the memorial halls of six independence activists. The bag design was developed using mechanic embroidery textile of 12 motifs manufactured in previous studies through the computer mechanic embroidery sewing machine, and the types were limited to totes, Boston, clutches, baskets, shoppers, hover bags, and hat boxes. The results of this study are as follows. First, it was found that the dense light and shade and delicate color expression of each motif design were the most important and achieved through the proper selection and utilization of embroidery yarn according to the mechanic embroidery expression technique for developing in-depth textile materials. Second, unlike in the past, when machine embroidery was difficult to handle, the spread of embroidery CAD and computer machine embroidery sewing machines made it easier for individuals to develop embroidery products. Third, this study once again emphasized the symbolism of Korean independence activists who sacrificed for the nation to exist at a time when it needs to be recognized due to the lack of fashion and diversity in cultural products containing historical and cultural meaning and values of the country. This study was able to develop computer machine embroidery textiles and various bag designs using various mechanic embroidery expression techniques that can highlight the symbolic image of each motif.

The purpose of this study is to analyze how the movie <The Book of Fish> (2021) represents Joseon, which is slowly collapsing with the Neo-Confucian order of the 19th century shaking, and to discuss its meaning. Prior to the analysis, the analysis framework of the historical drama was presented considering the narration characteristics of the historical drama. Using the analysis framework of historical dramas, we confirmed that <The Book of Fish> is representing the image of Jeong Yak-jeon and Jang Chang-dae living their lives as independent individuals between the limitations and possibilities of the times based on the plot structure of the narrative of exile. Through the central memory and surplus memory created through plot and style elements such as contrast between black and white and color images, voice-over narration, chinese poetry subtitles and music, the film asks us universal questions about what it takes to live as an independent individual.

The scale of visual expression has expanded from freeze frame to motion picture as media have developed. Moving pictures such as animation, movies, TV CM and GUI become formative elements whose movement is necessary compared to freeze frame as apparent movement phenomenon and unit structure such as short and scene appear. Therefore, of formative elements such as a shape, color, space, size and movement, movement is importantly distinguished in the moving image. The expression and form of image as a relationship between the signified and signifier explained by Saussure are accepted as a sign by mutual complement even though they limit the content. This makes it possible to infer that the formal feature of movement participates in the message content. To verify this, the result of moving picture visual perception experiment based on the gestalt grouping principle result shows that 70-80 percent of subjects think that 'movement' is the important grouping clue in perception. Movement affects the maintenance of the context of message content in the communication process when the meaning structure of moving picture is analyzed based on the structural feature. The identity can be maintained with if there is a movement with similar directive point even if the color and shape of people, things and background are changed. Second, the clarity of the content is elevated by a distinguished object as a figure by movement. Third, it acts as a knowledge representation which can predict similar movement process of next information processing. Forth, movement gives the content consistency even though more than two scenes have fast switch and complicated editing structure like cross-cutting. Movement becomes a clue which can make grouping information input by visual perception reaction. Also, it gives the order to the visual expression which can be used improperly by formation of structural frame of image message and has the effectiveness which elevates the clarity of signification. Moving picture has discourse with several mixed unit structures because it fundamentally contains time and the common and distinguished expression is needed by media-mix circumstances. Therefore, by the application of gestalt grouping principle to moving picture field, movement becomes the more distinguished than other formative elements and affects the formation of meaning structure. This study propose a viewpoint that develops structural formative beauty and new image expression in the media image field.

The blue-light effect on the grown as well as on the physiological activity of some major horticultural plants in Korea has been investigated. The light quality used for the work was obtained from sunlight filtered by an orangecolored polyethylene film which removed about 70% of visible light in the spectral region of $350㎚{\sim}500㎚$. The film was developed in this laboratory especially for the work and named BCR film meaning blue color-removing film. The light environment in the plastic house which was built with BCR film provided plants with the blue color-deficient sunlight. Thus, the photobiological effect of blue light could be examined conversely by comparing with the effect of white sunlight in a conventional plastic house built with colorless polyethylene film. In a sense of applicability to horticulture, two remarkable effects of the blue color-deficient sunlight on plant physiology were observed: First, it enhanced to a great extent the growth activity of plants-pepper, cucumber, zucchini, tomato, and leaf lettuce at the vegetative stage as well as at the reproductive stage, as demonstrated by their yield which were in average $40{\sim}50%$ increased compared with the control (under white sunlight). Second, it improved significantly the cold tolerance of plants, as exhibited with their resistance to chilling during treatment in a cold chamber maintained at a temperature which caused chilling injury to the plants of control. The visualized effects were reflected on the physiological activity of cells on organelle level. Chloroplast isolated from the plant leaves grown under BCR film showed considerably stronger photosynthetic activity, as judged by the increased electron transport rate of illuminated chloroplast, than that from leaves grown under white PE film. Mitochondria from leaves grown under BCR film maintained normal respiration activity until temperature decreased to a few degree($^{\circ}C$) lower than the temperature which caused respiratory inhibition to mitochondria obtained from leaves of the control.

As of 2019, for the 'Island I Want to Visit' project, Banwol and Bakji Islands, located in Shinan-gun, started color marketing to create a tourist attraction by painting roofs, buildings, and facilities purple. As this landscape change was evaluated as a 'dangerous but beautiful attempt,' it was recognized as the 'World's Best Tourism Village' in 2021, drawing attention from domestic and foreign tourists. However, the residents of the islands, who created and enjoy the benefits of the landscape, were alienated from the planning stage. This study investigated the meanings and symbols of residents' perceptions of the purple landscape. The cultural landscape frame of new cultural geography, which interprets the landscape's symbolic meaning and ideological signs, was utilized. In addition, a holistic approach was applied to understand the residents' perceptions of the multi-layered environment. Therefore, the perception of purple, the main color of the islands, the overall landscape and individual places, and the general perception of the Purple Island project were investigated. After the Purple Islands Project, the main senses for recognizing the villages focused on sight, and the residents were satisfied with the purple landscape as it improved the underdeveloped village environment. This satisfaction was based on lessening the negative memories experienced as an island rather than a value judgment on the purple color. In addition, the perception of the symbolic landscape, which has a social and universal system, has been subdivided and reorganized, including for tourism functions. It can be understood as an aspect of the spectacle landscape that appears in cosmopolitanism. However, in the process of transforming into a tourist attraction, it was discovered that the residents recognize the value of local resources and create a new cultural landscape. In addition, the perception of the relationship between Banwol and Bakji has also changed around tourism.

The realistic plan to establish a silver market in the clothing industries has not taken concrete shape, although the interest in the establishment of a silver market targeting the aged as a new custom group Is gradually Increasing because the rapid development of science and medical technology in the 20th century has led to an extension of lift and improvement of living conditions. The specialized business which produces and sells the clothing for the elderly is of small number and most of the clothes for the elderly are manufactured and sold by the companies for women's clothing in which change the size or length of the original works rather than reflect the bodily features of the elderly. The findings indicated that domestic brands showed the coordinated concept of a suit of jacket and slacks or skirts while the clothes were formed with a variety of coordinations centering around single article in the U.S brands. But, there was no difference in the use of natural materials centering around cotton and silk etc. and in the use of embroidery, lace and decorative details between the two countries. The knit brands of knit suit style in Korea were formed with the items focused on pull over and cardigan twin set, while the U.S brands were mainly formed with the design of knit suit style. The domestic knit brands were mostly developed with complicated patterns and gorgeous colors, while most of the U.S. brands were presenting a single or two tone color suit style and evening one-piece dress with a simple and modern style. The sporty casual brands of sporty casual style in Korea had a variety of colors and patterns focused on function and comfort for diverse leisure activities and daily life, while the U.S brands were established to present a variety of styles with the items of single article because they had a separate brand for casual even though it was not a exclusive brand for the elderly This study has a meaning in the presentation of the design idea considering the bodily shape of the elderly compared to the ready-to-wear considering the size alone, by examining the characteristics of bodice according to the physical change of the elderly women, analyzing the design of madam brand and the style of the ready-to-wear, researching the general circumstances of the brand for the elderly women, and highlighting the necessity of the elderly clothing market.
