The purpose of this study is to clarify the relationship between the visual sensibility and the decorative design of clothing. 41 kinds of costume samples have been selected from photographs in fashion magazines under detail and trimming, and divided into three types according to line, shape, and form. I have measured these images by using Semantic Differential method. The obtained data were analyzed by factor analysis ANOVA, discriminant analysis, regression analysis and MDS. The results of analysis are as follow; 1. Factor analysis has extracted five factors which consist of decorative design sensibility. These factors are Attractiveness, Hardness and Softness, Rhythm, Decorativeness, Cuteness. 2. There were significant differences in visual evaluation of decorative design and demographics 3. The discrimination among formative designs was closely related to decorative image, especially between line and form. 4. The Image effect on Preference, Buying needs, Riches and Pleasant was consist of complicated sensibility. 5. Evaluative dimensions of decorative design were identified by Simple-Complicated, Cubic -Plane perceptive image differed in degree of similarity in spite of same formative design.

This study was performed to quantify microscopically morphological characteristics of cotton fiber to identify parameters for quality evaluation using image analysis . The image of each fiber was captured by a Pc-based color imaging system using a conventional microscope. Ends of individual cotton fibers were glued on a microscope slide without any tension or straightening. A modified watershed technique was implemented to identify individual convolution segments, which were defined as sections of the fiber bordered by two neighboring convolutions. Length, area and perimeter of each convolution segment were measured directly from the image . Average width, shape factor and number of convolution segments in mm were calculated from the measured parameters. The performance of the image analysis algorithm was compared with visual varieties of cotton . The image analysis results agreed with visual inspection in 89.6% of the tested images.

Spatiotemporal data are records of the spatial changes of moving objects over time. Most data in corporate databases have a spatiotemporal nature, but they are typically treated as merely descriptive semantic data without considering their potential visual (or cartographic) representation. Businesses such as geographical CRM, location-based services, and technologies like GPS and RFID depend on the storage and analysis of spatiotemporal data. Effectively handling the data analysis process may be accomplished through spatiotemporal data warehouse and spatial OLAP. This paper proposes a multidimensional model for spatiotemporal data analysis, and cartographically represents the results of the analysis.

As the computer graphic technology has developed rapidly, the management of visual effects production has also changed. However, the insufficient rest and the inefficiency of communication have resulted in more pressure which would weaken the strength of the whole team. For searching the possible solution, this research has applied the SCRUM in VFX production and analyzed the impact of SCRUM for VFX project management. SCRUM was first used in the projects of software development, but now there are already many successful examples of introducing SCRUM into their facilities in various fields. This paper has used SCRUM in the experimental group and present methodology in VFX project management in the control group for the same project. Based on the analysis of the questionnaire investigation from both group with using t-test for data analysis, it has confirmed the credibility of the questions in the questionnaire index as α > 0.72. With the result of analysis based on the corresponding samples of the t-test, it shows the diversity of SCRUM for project management, and the convenience of communication within the team can enhance the team strength. Follow-up research will attend to provide more suggestions for applying SCRUM in other areas in project management.

This study tried to analyze the composition relation of a form in Korean traditional architecture through the viewpoint of visual perception and through the analysis by the number and quantity, and to analyze and implied relationship between the form composition of the traditional architecture and the principles of perception in the contemporary viewpoint by reviewing all the aspects on how to be perceived. Architecture has been studied in the relationship of the form and the space both existing together, so has Korean traditional architecture. But in the present condition with the construction norm of the traditional architecture-well known for its beauty in shape-and documents not existing, so that the study on Korean traditional architecture in the aspects of the form has to be undertaken on the basis of researching the existing architecture theoretically and architecture-relating documents actually. Therefore this study tries to review the mathematical principle and the ideological background of those days, and the attitude of ancestors treatment to the architecture by researching the existing architectural figure. Using mathematical analysis method with the basis of the above synthetically, this study aims at the analysis in the aspects of the visual perception on the form of Korea an traditional architecture.
