The image display is an Important component of PACS and of medical digital imaging chain. Displayed image qualify is affected by the physical characteristics of display device, appropriate clinical settings and calibrations, and ambient lighting conditions. The performance of display systems is continuously degraded over time due to luminance deterioration and changes of clinical setting parameters. A routine QC is recommended because the performance of display systems is continuously degraded over time. Ten flat panel monochrome LCD display devices were included in the evaluation of the QC effect. The effect of QC on primary class LCD medical display devices for selected QC tests was evaluated by comparing the performances, luminance response, luminance dependencies, display resolution and display chromaticity in this study, of before and after the calibration procedures. The effects of the QC are significant to luminance response and luminance spatial dependencies test and the other side, are slight to the display resolution and display chromaticity test. A routine QC of display device is essential for the consistency of medical image display and presentation. The study of the QC effects of display devices will play an important role in practical QC procedures of display devices.

As a pioneer of modem dance, $Lo{\ddot{i}}e$ Fuller($1869\sim1928$) was important because she introduced a free style dance using a new style of stage costumes. Also, $Lo{\ddot{i}}e$ Fuller was an important motif in $fin-de-si{\grave{e}}cle$, French arts, posters, sculptures, and so forth. This study aimed to clarify the characteristics of Fuller's dance and costumes, and to analyze the modernism in both. To better understand Fuller's dance, this article talks about research on Fuller's career, dance, and Fuller's own biography. Stage costumes, letters for patent, and photographs were are also studied. The most important elements of Fuller's dance were her costumes and the electric lights which could make free style expressions a fantastic representation of dance. To clarify the modernity of Fuller's dance, first of all, this study researched Fuller's career in dance and then analyzed representations of Fuller's dances in visual arts; posters, sculptures and lastly, the characteristics of Fuller's stage costumes. As a result, this article analyzed characteristics of Fuller's dance in three points. First, Fuller used sculptures of silk cloth's drapery to express physical movements and actions. Second, Fuller used lighting and electrical effects that had just been developed in the late 19th Century. Third, Fuller made an application for patents against stage costume and stage mechanisms for her original shows. This study focused on $Lo{\ddot{i}}e$ Fuller's stage costumes which played a main role in expressing fantastic sculptures for the first time in costume, visual arts, and dance studies. This study clarifies the characteristics of the stage costumes in Fuller's dance and is estimated as pioneering and fundamental research.

Two methods were used to detrermine the net photosynthetic rate(NPR) in the plug stand using a wind tunnel for plug seedlings Production. One is called as the integration method in which NPR calculated by the use of air current speed and $CO^2$ concentration measured at any heights above the medium surface in a wind tunnel were summed. It was assumed that the air flow at any layer did not mix with the lower or upper air layer. The other is called as the diffusion method in which eddy diffusivities above the plug stand were used to determine the NPR in the plug stand. In this method, $CO^2$ above or inside the plug stand was assumed to be absorbed vertically. NPR determined by the diffusion method was 28~45% of the NPR calculated by the integration method. Considering the magnitude of NPR and the effects of the air current speed on NPR, the integration method would be adequate for the calculation of NPR in the plug stand. Maximum NPR determined using the integration method appeared at the air current speed of 0.7m $s^{-1}$. It was ascribed to the decreased diffusion resistances of $CO^2$ with the increasing air current speed. NPR at the rear region in plug stand was 20~34% lower than that at the front region. NPR sharply decreased with the increase of an elapsed time after the beginning of photoperiod. Therefore $CO^2$ enrichment would be effective to force the growth of plug seedlings in a semi-closed ecological system under artificial lighting.

The subway lines have been expanded to solve the traffic problems in Korean cities, so that a big number of people daily use the subway stations. Therefore, subway stations became a kind of public space as well as traffic space. However, the underground space of the stations are essentially different with the aboveground space in terms of environmental and psychological terms. The color planning can be used to reduce the environmental and psychological disadvantages of underground spaces of subway stations. The purpose of this study is to understand the current design methods of subway stations' color planning. To achieve this purpose, this study investigates all reports of 'Color Planning for the Subway' which were used for the construction of subway lines in 6(six) Korean cities. After analyzing the design theories and methods used for the color planning, field studies have been done upon 10 subway lines of 6 cities, to find out the limitations of color planning, the differences between color planning and actual results. The conclusions are as follows : First, the color planning for subway stations does not seem to consider the characteristics of underground space and its psychological effects, such as the depth of station, the lighting source and methods. Second, some critical differences have been found between the color planning and the actual application during construction, due to arbitrary interpretation and limitations of color expression of the construction materials. Third, and therefore, the colors applied in stations do not perform their planned role such as 'variety in the unity', 'symbolic expression of the city and station'.

To improve the ocean waves of the ship maneuvering simulator, we study and summarize the visualization elements of the ocean waves and the overall direction of their implementation in detail. We categorize the visualization elements of the ocean waves into five groups, including wave surface, wave breaking, interaction, lighting effects, and underwater. We also analyze the design and implementation issues of the visualization of the ocean waves for ship maneuvering simulator with respect to realistic and real-time ocean visualization, ship dynamics, and application purposes. Through the analysis, we have found that the realistic visualization of ocean waves plays an important role in the generation of immersiveness, more accurate ship motion, and the various and controllable simulation scenarios for the ship maneuvering simulator. Additionally, we have confirmed that there are many visualization elements, methods, and limitations to be considered for the visualization of the ocean waves for ship maneuvering simulator, and we have concluded that the systematic design is required before implementation.

Recent digital camera development tendency shows the higher ISO extension which enables a user to take a picture in deemed lighting condition without using a flash or another equipment. Also noise reduction function has been developed to adjust the higher ISO extension. But using the high ISO causes a lot of noises so that proper noise reduction function should be adjusted. So the manufacturers introduce the advanced noise reduction function with higher ISOs as the digital camera performance development. On the other hands, the defect of noise reduction is not widely open such as remaining noise in high ISOs and decreasing resolution. Therefore, in this research we verify and experiment the decrease of resolution by using noise reduction function on a digital camera. Moreover we analyze the results how much the noise reduction function effects to the image resolution. And we present the results as practical numerical values.

Tunnel sections on the expressway are different from rest of sections on the expressway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Thus, this study tried to find out qualitative factors affecting speed reduction in tunnel sections based on questionnaire surveys and its analysis in tunnel sections selected by taking consideration of diverse conditions. Analysis showed that factors concerning tunnel configuration (lane width, shoulder width, and tunnel length) related to very long tunnels increasingly popular recently had some effects on reduced speed inside of tunnels. It appeared that visual environment such as visibility of tunnel entrance had an impact in speed reduction and vehicle speed tended to change according to lighting illumination level inside of tunnels. It is expected that continual investment would be made in technological development related to expressway tunnel design and service improvement based on this study.
