Variation of viewing position of the observer is one of factors of image distortion in the stereoscopic display. A rotation movement of the observer makes the stereoscopic image distortion and that is caused by different horizontal position of each eye of the observer. It is different from horizontal and depth directional movement of the observer. In this paper, we showed the numerical simulation result about the distortion analysis and the correction of the stereoscopic image in rotation movement of the observer.

Effects of such factors as polymerization temperature and a newly synthesized oligomeric photoinitiator(PEDI380) on the electro-optic characteristics of polymer/LC composite films prepared by the UV-curing method were investigated. The polymer-dispersed liquid crystal cells were made with oligomeric photoinitiator PEDI380 by UV-curing method exhibited both low driving volta ge($V_90$) and high contrast ratio under optimum formulation condition.

The mechanism of striation in the coplanar- and matrix-type plasma display panel (PDP) cells has been studied using the particle-in-cell Monte-Carlo Collision (PIC-MCC) model. The striation formation is related to the ionization energy of neutral atoms and the well-like deformation of space potential by space charge distribution. Negative wall charge accumulation by electrons on the MgO surface of the anode region is also one of the key factors for the formation of striation. The clearness of the striation phenomenon in PIC-MCC code in comparison with fluid code can be explained by using nonlocal electron kinetic effect.

The readability and the visuability are very significant when the letters or figures are displayed as static visual information. Not only is the beauty of the body type character(small letters) important but the display type character(large letters) should also be read easily, quickly and precisely. The issue regarding the readability in terms of perception of information has been raised continuously for all kinds of small signage and billboard, etc., which are written in display type within our everyday life. Among the various kinds of small signage and billboards the car licence plate is well known. Among all the possible factors that would have made an impact on the readability of licence plate, this paper focused on the effects of arrangement of character(letters and figures) and contrast of colors for the readability of licence plate using the within-subject analysis. The statistical analysis results in error reading rate, the character arrangement were significant but the color contrast(green/white, white/green, blue/white, white/blue, black/yellow) was not, No interaction was found.

Organic light-emitting devices (OLEDs) with the high efficiency and long lifetime are of growing interest in next-generation displays. Among the factors influencing OLEDs properties, one of unstable factor is $Alq_3$ cationic species caused by the excess holes resided in $Alq_3$ layer. Therefore, we suppressed the accumulation of excess holes by using the mixed-hole transporting layer (MHTL) of NPB and CBP in multilayer green OLEDs. The devices with MHTL showed improved characteristics in the luminance efficiency and lifetime. More characteristics and the carrier transport mechanism will be discussed.

A three-dimensional (3D) display system based on computer-generated integral photography (CGIP) is proposed and its feasibility is discussed. Instead of the pickup process in conventional If, the elemental images of imaginary objects are computer-generated. Using these images, we observed autostereoscopic 3D images in full color and full parallax. The lateral and depth resolutions of the integrated images are limited by some factors such as the image position, object thickness, the lens width, and the pixel size of display panel.

The objective of this study was to determine the influence of women's attitudes toward women's underwear on image-creation efficacy and appearance management attitude. A total of 405 surveys of women working at an industrial complex in the Daegu-Kyoungbuk area were used for data analysis. Frequency, factor analysis, reliability analysis, and regression analysis were used for data analysis. The findings were as follows. The sub-factors of women's attitudes regarding women's underwear were found to be 'aesthetics/body-style compensation', 'ostentation', 'functionality', and 'manner estimation' and the sub-factors of image-making efficacy were 'display confidence', 'face-image confidence' and 'display ability'. Appearance management attitude had factors such as total coordination, weight management, skin management, and pursuit of change. Aesthetics/body-style compensation, functionality, and ostentation, which were sub-variables of attitudes toward underwear, had a significant influence on image-creation efficacy. Aesthetics/body-style compensation and ostentation had significant influences on appearance management attitude. Aesthetics/body-style compensation was found to have a significant influence on all sub-variables of both image-creation efficacy and appearance management attitude.

This study investigated store attributes, VM factors, and store loyalty for store choice behavior by G sensibility types. A total of 425 usable questionnaires were obtained from students who enrolled at universities in Busan, Korea. For data analysis, factor analysis, cluster analysis, ${\chi}^2$-test, and ANOVA were conducted by using SPSS 10.1. The major results were as follows: First, G sensibility was classified into five types: G1(My pace type), G2(Active type), G3(Whimsical type). G4(Mania type), and G5(Sensational type). Particularly, G3 was most highly observed in male and female groups. Second, there was significant difference in the importance of store attribute, such as merchandise assortment among G sensibility types. Third, there were significant differences in VM factors of store image, physical facilities, and display and layout among G sensibility types. Especially, G5 type consumers considered store image, physical facilities, and merchandise display and layout more importantly, than did the other types. Fourth, there was significant difference in store loyalty among G sensibility types. This study discussed managerial implications of visual merchandising strategy for apparel retailers.

Work environments have been changed with the advent of new technologies, such as computer technology. However, human cognitive limits can't pace up with the change of work environment. Designing human-computer system requires knowledge and evaluation of the human cognitive processes which control information flow workload. Futhermore, under limited reaction time and/or urgent situation, human operator may the work stress, work error and resultant deleterious work environment. This paper evaluate the visual factors of major information processing factors(information density, amount of information, operational speed of speed)on operator performance of supervisory control under urgent(limited reaction time)environments which require deleterious work condition. To describe the work performance int the urgent work situations with time stress and dynamic event occurrence, a new concept of information density was introduced. For a series of experiments performed for this study, three independent variables(information amount, system proceeding speed, information density) were evaluated using five dependent variables. The result of statistical analyses indicate that the amount of information affected on all of five dependent measure. Number of failure and number of secondary task score were influenced by both amount of information and operational speed of system. However reaction time of secondary task were affected by both amount of information and information density. As a result, the deleterious factors for the performances seemed to be a scanning time to supervise each control panel. Consequently, a new display panel was suggest to reduce operator work load for scanning task showing better operator performance.
