  • The farm house structure, ventilation system and manure treatment of two-storey buildings and sawdust pig houses were surveyed and analyzed. Based on the data for ten selected farms in five provinces during eight months, the goal is to eventually establish a standard two-storey pig house. Manure treatments were composting, slurry and activated sludge in two-storey pig houses, while fermentation method was done in sawdust pig house. The depth of sawdust as a litter material were 10 to 60cm, with a duration of 1/2, 1, 3 and 6 months, respectively. The ventilation systems were the mechanical type in two-storey pig houses and natural system in the sawdust pig house. Side wall in the two-storey pig house was enclosed with insulation materials such as block, colored metal sheet and sandwich panels. The minimum ceiling height in the first floor of the two-storey pig house was 2.0m and the maximum was 3.0m. On the second floor, ceiling height ranged from 2.0 to 2.7m. The construction cost in the two-storey systems were $700\~140$, and sidewall curtain systems were $30\~40$ thousand Won/pyung.

  • In this paper, electroencephalographic (EEG) signal of one among subjects measured biosignal with visual evoked stimuli inducing the concentration was analyzed to detect the changes in the attention status during attention task fulfillment from January to February, 2011. The independent component analysis (ICA) was applied to EEG signals to isolate the attention related innate source signal within the brain and Electroculogram (EOG) artifact from measured EEG signals at the scalp. The consecutive accumulation of short time Fourier transformed (STFT) attention source signal with excluded EOG artifact can enhance the regular depiction of EPOCH graph and spectral color map representing time-varying pattern. The extracted attention indices associated with somatosensory rhythm (SMR: 12-15 Hz), and theta wave (4-7 Hz) increase marginally over time. Throughout experimental observation, the ICA with STFT can be used for the assessment of participants' status of attention.

  • To achieve the advertising objectives, we must first draw out consumer's advertisingto advertising, and then realize the data processing course from comprehension to the retention of the advertising contents. In current media environment, however, the value of advertising as the method of attracting consumer's attention is declining due to the current situation of newspaper and magazine advertising as follows. As for newspapers, competitive messages are increasing on a continuous basis; the size of advertising section and the number of newspaper pages has been increased along with the popularization of color advertising. As for magazines, more pages are allocated for advertising rather than for the actual contents. In such communication environment, it is believed that only the advertising capable of uniquely appealing to consumers can achieve the purpose of advertising. Hence, this research attempts to discuss the effective ways of promoting attention in print media through the case studies covering the design principles relating to layout and the layout format, among the visualization processes related to the consumers'memory.

  • To improve the performance of the inverse halftoning, smoothing masks should be designed optimally by using the accurate information of halftone cells. In this thesis, the method of energy minimization is so defined as to determine the exact information of halftone cell. A heuristic search method is proposed to obtain efficiently the parameters of halftone cells which determine the minimum energy. A halftone-peak modeling method with several functions is proposed and used to get initial values of the parameters. The dimension decomposition technique is also adopted to speed up the search process of energy minimization. Several experiments show that the proposed method extracts correct location of the seed pixel of the halftone cell and the extracted information of the halftone cell can be used to get more exactly smoothed color images. The proposed method can be applied to extract the texture patterns, to separate channel images of a scanned color halftone image, and to extract the moire area in an image.

  • We propose a color transfer method that used color contrast based templates to express the visual difference clearly between objects, while remaining the quality of the input image. Our algorithm employs colors of both the input image and template distributed on the $a^{\ast}b^{\ast}$chrominance plane of CIE $L^{\ast}a^{\ast}b^{\ast}$color space. The templates are made by considering the effect of color contrast and have the shape of either a line or a curve represented color distribution of the basic colors based gradation image. These tempates can be modeled on spline curves. We also generate simply new templates with the different basic colors by moving the control points of that curve. The color transfer method using the templates is done through a regressive analysis and color matching. We maintained color coherence of the input image by transforming similarly the color distribution of an input image to the one of templates.

  • The research for extracting man-made features such as building and road from the aerial photograph or satellite imagery has been performed actively. As lately the resolution of digital aerial photographs was improved, unwanted features(noise) would be often detected. An edge detection algorithm is developed to make up for such a noise problem, make boundaries of wanted objects clear and extract only needed features. The algorithm developed in this research performs separating RGB channels, differencing between channels, transforming in to binary images, excluding noises and restoring shapes, and edge extraction in order. The images to be used for edge detection are prepared through bundle adjustment, DTM extraction, orthorectification and mosaicking. The roof edges of small building on preprocessed digital aerial orthophotos were extracted using the algorithm developed in this study. The validity of the algorithms was proved by comparing edge results of small building extracted in this study with those of conventional methods.

  • Korea had suffered the colony of Japanese imperialism and the Korean War from the invasion of the external circumstances. Such special situation made new influences on the clothing habits. The types of Korean women clothing could escape from the traditional style that had been maintained for thousands of years. The foreign clothes for Korean women had undergone various changes from the Liberation in 1945. The jackets that had been introduced to Korea at the Enlightenment period had become popular outfits for men. The jackets made big influences on the changes such as the social advances for women from the times background of the Liberation. The jackets possess very important meaning for the changes in the diffusion of feminism and fashion. Therefore, this research tries to investigate the forms, silhouettes, changes and structures of the jackets such as the locations of the collar, the sleeve, and the waste line. The process of the changes in the style of women jackets is also analyzed from the silhouette and the structure method. The development and changes will be understood of Korean women's jackets. The Korean women's jackets should also be examined further with the history of foreign clothing from now on. The fashion to be introduced from important society cultural phenomena and the Western Europe has been reflected into the changes in the style of Korean female jackets. Also, dramatic changes in the style of clothing indicate that the society had experienced a great deal of changes. It is verified that foreign clothes have been interacted with the stream of times worldwide. After the Liberation, the female jackets become a uniform style which just followed the Western European style. However, a season trend has been announced from the SFAA since 1990. Since then trendy jackets have been detailed more with this chance.

  • In this paper, we design and implement a system which recognizes and tracks a human head on a sequence of images. In this paper, the color of the skin and ellipse modeling is used as feature vectors to recognize the human head. And the modified time-varying edge detection method and the vertical projection method is used to acquire regions of the motion from images with very complex backgrounds. To select the head from the acquired candidate regions, the process for thresholding on the basis of the I-component of YIQ color information and mapping with ellipse modeling is used. The designed system shows an excellent performance in the cases of the rotated heads, occluded heads, and tilted heads as well as in the case of the normal up-right heads. And in this paper, the combinational technique of motion-based tracking and recognition-based tracking is used to track the human head exactly even though the human head moves fast.

  • The purpose of this study is to analyze the image evaluation and the preference of tailored jacket focused on the collar's figure according to the body type and the degree of satisfaction with their body of middle-aged women. For this study, twenty seven different types of tailored jacket were designed with some variation of their silhouette, the length and the collar's figure on three hundred and twenty three middle-aged women ranging from 35 to 50 years old. There was a significant difference in the image evaluation and the preference of tailored jacket according to the body type of middleaged women. The women of the type 1 evaluated that portrait lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 2 evaluated that breast lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 3 evaluated that breast lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 4 evaluated that waist lapel collar were the most fascinating, elegant and active, tender and they preferred that style. There was a meaningful difference in the image evaluation and the preference of tailored jacket according to the degree of satisfaction with their bodies. As satisfied with their face size, they thought breast/portrait lapel collar were more attractive, graceful and active, soft and they preferred that style. As satisfied with weight they regarded portrait lapel collar as more attrative, graceful and active, soft and they preferred that style. In this study we found that the middle-aged women evaluated the tailored jacket which was looking esthetic and fitting their body types, as the most attrative, elegant, active, and tender clothing and they prefered that kind of tailored jacket.
