  • This study examines changes in consumer perceptions of fashion shows, which are critical elements in the apparel industry and a means to represent a brand's image and originality. For this purpose, big data in clothing marketing, text mining, semantic network analysis techniques were applied. This study aims to verify the effectiveness and significance of fashion shows in an effort to give directions for their future utilization. The study was conducted in two major stages. First, data collection with the key word, "fashion shows," was conducted across websites, including Naver and Daum between 2015 and 2018. The data collection period was divided into the first- and second-half periods. Next, Textom 3.0 was utilized for data refinement, text mining, and word clouding. The Ucinet 6.0 and NetDraw, were used for semantic network analysis, degree centrality, CONCOR analysis and also visualization. The level of interest in "models" was found to be the highest among the perception factors related to fashion shows in both periods. In the first-half period, the consumer interests focused on detailed visual stimulants such as model and clothing while in the second-half period, perceptions changed as the value of designers and brands were increasingly recognized over time. The findings of this study can be utilized as a tool to evaluate fashion shows, the apparel industry sectors, and the marketing methods. Additionally, it can also be used as a theoretical framework for big data analysis and as a basis of strategies and research in industrial developments.

  • A system for microseismic monitoring due to underground displacements is being operated in several mining areas in order to analyze ground subsidence. Microseismic monitoring system mainly consist of three components; 3-component geophone, data logger and analysis program. The previous analysis program had found the location of microseismic source by analysing only first arrivals of P-waves, but the upgraded analysis program has improved accuracy of the location by analysing both P- and S-waves. This analysis program also has upgraded the function to calculate the microseismic magnitude by using regional specific coefficient and microseismic amplitude. Also the program has upgraded the function to confirm visual location of microseismic source by superimposing field aerial photographs and the results.

  • Monitoring water surface has become one of the most prominent areas of research in addressing environmental challenges.Accurate and automated detection of watersurface in remote sensing imagesis crucial for disaster prevention, urban planning, and water resource management, particularly for a country where water plays a vital role in human life. However, achieving precise detection poses challenges. Previous studies have explored different approaches,such as analyzing water indexes, like normalized difference water index (NDWI) derived from satellite imagery's visible or infrared bands and using k-means clustering analysis to identify land cover patterns and segment regions based on similar attributes. Nonetheless, challenges persist, notably distinguishing between waterspectralsignatures and cloud shadow or terrain shadow. In thisstudy, our objective is to enhance the precision of water surface detection by constructing a comprehensive water database (DB) using existing digital and land cover maps. This database serves as an initial assumption for automated water index analysis. We utilized 1:5,000 and 1:25,000 digital maps of Korea to extract water surface, specifically rivers, lakes, and reservoirs. Additionally, the 1:50,000 and 1:5,000 land cover maps of Korea aided in the extraction process. Our research demonstrates the effectiveness of utilizing a water DB product as our first approach for efficient water surface extraction from satellite images, complemented by our second and third approachesinvolving NDWI analysis and k-means analysis. The image segmentation and binary mask methods were employed for image analysis during the water extraction process. To evaluate the accuracy of our approach, we conducted two assessments using reference and ground truth data that we made during this research. Visual interpretation involved comparing our results with the global surface water (GSW) mask 60 m resolution, revealing significant improvements in quality and resolution. Additionally, accuracy assessment measures, including an overall accuracy of 90% and kappa values exceeding 0.8, further support the efficacy of our methodology. In conclusion, thisstudy'sresults demonstrate enhanced extraction quality and resolution. Through comprehensive assessment, our approach proves effective in achieving high accuracy in delineating watersurfaces from satellite images.

  • A low-cost, simple strip reader system using a linear movement mechanism of CD-ROM deck has been developed to characterize a lateral flow membrane-based immunochromatographic assay. The test strip reader was assembled by a CD-ROM deck and home-made optical head especially designed for immunoassays. The optical head for detecting reflected light from the test strip surface consists of green light-emitting diode, large area silicon photodiode, and anodized aluminum mounting block providing a slit structure for cutting light from the LED. The stepping motor of the deck was operated in the full step mode, whose distance of each reading point is about 0.15mm. The performance of the strip reader was tested by analysis of HBV(hepatitis B virus) antigen test kit. This strip reader can be useful for inexpensive, disposable, and membrane-based assays that provide visual evidence of the presence of an analyte in a liquid sample.

  • We have cloned a cDNA for an opsin (Boceropsin) from the silkworm larval brain which was suggested to contain the photoperiodic receptor. Its deduced amino acid sequence was composed of 381 amino acids and included amino acid residues highly conserved in insect visual pigments. This opsin belonged to the long wavelength photoreceptor group of insect opsins, and are presumed to be photoperiodic receptor. RT-PCR analysis revealed that Boceropsin mRNA is expressed in the larval brain, but not in the subesophageal (Sg) and thoracic ganglion. Immunohistochemical analyses demonstrated that Boceropsin protein is present bilaterally in some defined cells localized in the brain of the Bombyx larva. Boceropsin was considered not to be involved in the circadian photoreception, because carotenoids are not indispensable for the photoreception and formation of circadian rhythms in the silkworm.

  • The purpose of this study is first, to see through the aesthetic essence of the clothing as art, through theoretical consideration of cultural feature and body style in Postmodern Feminism. Also, this study will examine the aesthetic value in artistic meaning regarding a Deformational body image in visual an. Second, this study will analysis the formative character of Modern Art to wear which expressed unfixed body style, followed by the change of Postmodern Feminity, as a Deformation image. This character will be categorized by Expansion, Grotesque, Pleasure, and Virtuality. The following is the result of this study. Expansion expressed in modern Art to wear created intentional structure of the form, and intentionally presented refusal of body existence through disembodied. Grotesque expressed refusal and deviation of women's ideal body style, which is defined by mannish discourse, very grotesquely. Pleasure pleasantly presented free emotion through an intentional transformation like distortion or imbalance of the body By paradoxically reproducing women's virtual body as other unfixed female identity was expressed visually through virtuality to embody post-gender.

  • This study aims to find the architectural concepts of Song-Sun and the spatial structure of the Myonangjong through kasa, sijo, and Chinese poems. He considered his place as a ideal place to dwell a secluded life which is surrounded by mountains, and opened to a field in front. That places is connected with geomancy or Feng Sui, and he attached great importance to placeness of the Myonangjong as a pavilion. As his place was called 'tyoro samgan', his place should be simple, and that was harmonized with nature. He regarded his place as a part of the outside space and its surrounding nature. As the pen name of Myonangjong shows that his way of life is very pure so he need not disgrace against the earth and the sky, he considered his building as a place of embodying the Confucian great law of heaven and earth. Myonangjong has a concentric circle structure of the scenery which is viewed panoramically along with the visual direction.

  • The purpose of this paper is to find out and to show that the probability of the adaption of YURAGI theory of wall covering in interior design. By using personal computer, visible image of wall covering is inputted to a computer program as 'bmp' file, Windows bitmap file format, for Fourier transform. The evaluation indexes such as 'Map', 'YURAGI coefficient', 'Rest error', and 'Linearity' are defined to display the analytical result. The result of this study is shown by visual image and numerical value. As a result of this paper, we can understand that the psychological evaluations about wall coverings are different according to the YURAGI coefficient which came out by fluctuation analysis method as YURAGI theory. So, now we are able to know that the adaptation of YURAGI theory is very useful at psychological evaluation about wall covering.

  • Laboratory experiments were peformed to understand physical properties of soil-cement column under the influence of acidic flow including metal contaminants and its retaining capacity against metal migration. The contaminant used in this study was nitric acid with Cu and Cd. The Permeability of soil-cement column decreased when pH of the column began to drop below 12. Decreases in pH led to significant reduction of compressive strength of clayey soil-cement specimen, while relatively marginal reduction for sandy soil-cement specimen. The metal contaminants did not leachate from soil-cement column until pH of soil-cement dropped below 7∼8 for Cu and 9∼10 for Cd. Metal contaminants were precipitated and trapped inside the soil-cement column at pHs higher than those mentioned as verified with metal analysis and visual inspection. This indicated that soil-cement column not only performs well as a cut-off wall, but also helps alleviating the level of contamination of the surrounding environment.
