  • In this paper, we designed a Holter analysis system using the visual programming method. It differs from the existing analysis system in that the various signal processing algorithms represented by icons were designed by GUI concept which provide unskilled user with easy and convenient analysis environment. In order to analysis ECG signal, we only select the icon representing a algorithm to be applied by mouse and arrange the selected icons upon the order to be processed on screen. As a result it provides a convenient usage and flexibility of analysis. Finally, we can find the optimal algorithm for the ambulatory ECG analysis by comparing the several results obtained from the various analysis configuration.

  • Using semiotic analysis, visual images in selected postmodern fashion advertisements were analyzed. Semiotics is the study of the structure of the meanings of signs. Semiotic analysis involves deconstruction, and thus draws on the researcher’s value-mediated introspection and subjective interpretation of texts i.e., ads). Through deconstruction, culturally assigned meanings, which represent consumers and culture, were revealed. Postmodern characteristics including open interpretation, use of the human body as an object, multi page format, new mood, black and white scenes, use of real people, and new ideology were identified in the ads. The importance of analyzing visual images in fashion ads was stressed in the findings of the study, as was the importance of educating consumers on how to read the visual images.

  • In the multi-pass shape drawing process, it is important to design the intermediate dies for producing sound products. Up to now, the design of the intermediate dies is mainly carried out by the industrial experts based on their experience. In this study, a design program was developed to design the intermediate dies for multi-pass shape drawing process. The program was programmed by using VisualLISP. In this program the intermediate dies can be designed by using the initial material shape and the final product shape. In order to verify the effectiveness, the program was applied to design the intermediate dies of multi-pass shape drawing for producing four teeth spline and gun slide. Finally, FE analysis and shape drawing experiment were performed to verify the effectiveness of the designed intermediate dies. As a result, it was possible to produce the drawn products with the required dimensional accuracy.

  • In recent years, the Guochao style of virtual idols has proliferated, and the virtual idol market in China has witnessed gradual growth. As Guochao combines traditional Chinese culture with modern aesthetics, it shapes a distinctive visual identity for Chinese virtual idols. We address the current research gap by exploring the characteristics of Guochao style in virtual idol design through literature analysis, semiotics, and comparative studies. We examine how Guochao virtual idols represent the convergence of Chinese culture and modern technology, reflecting cultural characteristics of the era. Through our analysis of virtual idol design, we identify key design features of Guochao virtual idols, bridging a theoretical void in this area. We propose recommendations to foster a more dynamic and culturally enriched virtual idol industry in China. Our research provides new insights into integrating Guochao elements into virtual idol design as an approach to differentiate amid competition while promoting traditional Chinese culture through digital media. We demonstrate how this design approach enhances the uniqueness and cultural value of Chinese virtual idols, contributing to the field's theoretical foundation and practical applications.

  • Purpose: The purpose of this study is to investigate the effects of visual activation and quantitative analysis of regional cerebral blood flow. Visual activation was known to increase regional cerebral blood flow in the visual cortex in occipital lobe. We evaluated that change in the distribution of $^{99m}Tc-HMPAO$ (Hexamethyl propylene amine oxime) to reflect in regional cerebral blood flow. Materials and Methods: The six volunteers were injected with 925 MBq (mean ages: 26.75 years, n=6, 3men, 3women) underwent MRI and $^{99m}Tc-HMPAO$ SPECT during a rest state with closed eyes and visual stimulated with 8 Hz LED. We delineate the legion of interest and calculated the mean count per voxel in each of the fifteen slices to quantitative analysis. The ROI to whole brain ratio and regional index was calculated pixel to pixel subtraction visual non-activation image from visual activation image and constructed brain map using a statistical parameter map (SPM99). Results: The mean regional cerebral blood flow was increased due to visual stimulation. The increase rate of the mean regional cerebral blood flow which of the activation region in primary visual cortex of occipital lobe was $32.50{\pm}5.67%$. The significant activation sites using a statistical parameter of brain constructed a rendering image and image fusion with SPECT and MRI. Conclusion: Visual activation was revealed significant increase through quantitative analysis in visual cortex. Activation region was certified in Talairach coordinate and primary visual cortex (Ba17),visual association area (Ba18,19) of Brodmann.
