The purpose of this study is analyze physical and textual characteristics of the fold screen with Gosi(고시), tour ancient poems own by Beopjusa temple(법주사) in Mt. Sokrisan(속리산). The calligraphic specimen of this fold screen is written by King Seonjo(선조), and it seems to be made by between 1725 and 1758. On the view of physical point, the size of the fold screen is 190.0cm high, and 67.2cm wide each fold. And its format is made by 8 fold screen and its calligraphic style is a ‘cursive’ style. It was printed by wood block printing with chinese ink on the Geonji(견지). On the view of textual point, the fold screen of Gosi(고시) is consist of four ancient poems, and its content is describe to yearning for the appearance of the true gentleman possessed with high principles and virtue. And the four ancient poems is arranged by a well organized passage.

Size reduction is one of the major pre-processing operations in using biomass as a source of energy or raw materials for forest products industry. The grinding characteristics of dried yellow poplar wood chips were investigated using laboratory knife mill with three different screen aperture diameters to provide the basic information for the optimizing of size reduction processes in biomass industry. Average specific energy consumptions were 0.157, 0.137, and 0.093 Wh/g for the screen aperture diameters of 5.0, 7.5, and 9.0 mm, respectively. According to the results of size distribution analysis of ground particles, the sizes of the most of ground particles were much smaller than the aperture diameters of the screens installed on knife mill used in this study.

In this study, a star screen model was constructed to predict the dynamic characteristics of interactive waste particles and to simulate separation capability of the particle using geared type screen(star screen). In order to approach this model, it is necessary to determine the design parameters of the screen such as driving torque, percentage of open space, and capability. Thus, a dynamic star screen model was developed with a total of 32 columns of geared assembly including screen part, wastes guide, and extra joints to rotate the screen using ADAMS. Each parameter was simulated to predict the screening capability for particle size, rotating speed, and particle condition. From the results, separation ability was predicted according to the affecting variables by using the dynamic star screen model.

In the case of projection type display, it needs to use the screen in order to project the image clearly and wide viewing angle. We have been developing the step in type display system using the smoke screen. However, the image with smoke screen was flickered by gravity and air flow. Then we considered to reduce the flicker of the image and we found that flicker can be reduced and viewing angle becomes more large. This time we report the large viewing angle step in type display system using screen made up with very small particle size smoke and flow controlled nozzle. Hence, at first we considered the most suitable particle for the screen and then the shape of screen and then we constructed the array of flow controlled smoke screen. By the results of experiment we could get considerably high contrast flicker-less image and get the viewing angle more than $60^{\circ}$ by this flow controlled nozzle attached new type smoke screen and make clear the efficiency of this method.

Fine powders of $\alpha$-Fe2O3 were prepared by precipitation method using iron (III) nitrate in ethanol solvent and the thick film using this powder was made by the screen printing technology. Effects of the reaction temperature and concentration of the iron (III) nitrate on the particle size and specific surface area were studied. Also, the relationship between the powder size and properties of the thick film was discussed.

This paper is to research the heat transfer characteristic performance of the copper-water heat pipe with the screen wicks. Recently, the semiconductor capacity of an electronic unit has been larger, on the contrary, its size has been much smaller. As a result, a high-performance cooling system is needed. Experimental variables are inclination angles, temperatures of cooling water and the mesh number of screen wicks. The distilled water was used for the working fluid. At the inclination angle $6^{\circ}$ in top heat mode, the two layers of the 100-mesh screen wick showed the best heat transfer performance. The thermal resistance of the two layers with the 100-mesh screen was 0.7~$0.8^{\circ}C$/W.

Recently, as the demand for multimedia services based on the wireless technologies and mobile devices increases, Full-touch screen mobile devices adopting touch screen keyboards are emerging to cope with the limited display size and take advantage of the flexibility in the design of user interfaces. However, the text entry task, which is one of the main features of the mobile devices, decreases the competitive advantages of the touch screen keyboards over the physical keyboards or keypads due to the lack of physical feedbacks and the frequent occurrence of mistyping. This study aims to introduce a novel text entry method named Fuzzy Touch and compare this method with the conventional text entry method on a touch screen keyboard in terms of the performance (time, number of touch) and the subjective ratings (ease of use, overall preference).

A real time tracking and matching of the screen cursor corresponding to the iris moving by measuring distance between vertical movement and horizontal movement of iris is presented in this paper. The screen cursor is tracked and matched with the distance md direction moving the center-positioned coordinate of iris. The experimental result shows that the moving of iris and screen cursor are accord with distance and size of screen and the optimal tolerance is reduced the tracking error.
