The purpose of this study is to analyze psychological and physiological effects accordance with viewing and walking in the forest and urban area. In the result of measurement of physiological reactions in nervous system, viewing of the forest had a calming effect on the nervous system by reducing blood pressure and heart rate. The other hand, viewing and walking in the urban area compared to the forest area raised stress by increasing blood pressure and heart rate. In addition, viewing in forest area was effective in stress relief by noticeable reduction of the amylase concentration. In contrast, walking in the urban area was also confirmed an increase of stress by increasing the concentration of the amylase. A viewing and walking in forest area was effective in alleviating depressed on anxiety, anger, fatigue and confusion.

Viewing zone shape and size perform a key role in creating viewing comfort for the viewer. The horizontal and vertical sizes of viewing zones, formed by a full color transmission type holographic screen with a stereoscopic image projection are investigated. The screens have been recorded as holograms of a narrow stripe shaped object with different width; to extend the vertical size of the viewing zone the holograms were exposed two times with the hologram shifting between exposures. The viewing zone parameters were measured as a function of the stripe width of the object and of the exit pupil size of projection optics for several holographic screens having the size of the 30 $\times$ 40 $\textrm{cm}^2$.

Because of its weak points that narrow viewing angle and grayscale inversion, 'bare' twisted nematic (TN) LCD has some limits to use as a display device, though its great strong points that low cost, high yield, simple design, high transmittance and normally white. The 'WideView(WV)' film which introduced by Fuji co., has been good solution to extend the viewing angles of TN mode, therefore that film have been used generally for TN panels needed wide viewing angle. This paper introduce the research to find the parameters of the Wide view film and a TN panel which affect viewing angle characteristics and how to adjust those parameters.

The purpose of this study is to help the students in middle school improve their English listening comprehension by presenting effective teaching and learning techniques using animation. A good animation provides a self-contained world with language expressed in a virtual context. A few animation such as "Mulan", "The Emperor's New Clothes", and "Gulliver's Travel" are presented. The materials are primarily for English listening comprehension, enhance awareness of American culture and life-styles, and to encourage students' active role in learning English. It is suggested that their use with content-based instruction, where animation provides relevant schema background, makes language relevant and comprehensible. Practical aspects of classroom instruction are discussed, focusing on the adaption of pre-viewing, while-viewing, and post-viewing activities to the selected animation. It is concluded that careful animation selection, purposeful lesson planning, and the integration of pre-viewing, while-viewing, and post-viewing activities into the content-based lesson encourage natural language skills, especially the listening comprehension and students' interest in English.

In this paper, we designed a tabletop display which enables two viewers each to see a different image simultaneously within his/her defined viewing zone. In order to construct the designed viewing zones, we found the basic design conditions for a parallax barrier with a commercial LCD panel. As the viewing zones for two viewers are formed with only two view-point design, the interval between the center positions of each viewing zone and the width of each viewing zone are small compared to designed values. We analyzed the primary cases, introduced two modified design methods to enlarge the interval and the width of the viewing zones, and simulated their characteristics. As designed with six unit view-point and each viewing zone of each viewer is formed with a merged view-point, we found that adequate interval and width of viewing zones can be made, and we verified it in comparison with the tabletop display module that we fabricated.

This study examined the influence of viewing motivation of the Korean wave video content on viewing attitude, national image of Korea, and behavioral intention among users of the Chinese online video platform, 'bilibili.' Using an online questionnaire, a total of 355 copies were collected. The data were analyzed using structural equation modeling. The findings indicate that the four items of viewing motivation (i.e., entertainment, information, relationships, and vicarious satisfaction) exerted a positive impact on the viewing attitude, while real-time discussion showed no significant impact on it. In addition, viewing attitude exerted a significant positive impact on the national image of Korea, which in turn showed positive influences on the behavioral intention (i.e., visit intention, WOM intention). This study contributed to expand the literature by discussing the Chinese major online content platform, Korean culture, and visit intention to Korea focusing on the Korea wave content. A series of theoretical and practical implications were discussed along with the directions for future research.

Purpose: This study was to investigate the properties and the location of neural reorganization following eccentric viewing training. Methods: 14 subjects with normal vision took part in eccentric viewing training. The measurements of the light sensitivity and multifocal electroretinogram were performed before and after the training. Results: The measurements of the light sensitivity and multifocal electroretinogram for pre-eccentric viewing training and post-eccentric viewing training showed the significant difference (p<0.047 and p<0.028, respectively). Conclusions: The retinal outer plexiform layer is unable to regenerate. However, the neural reorganization in the retinal outer plexiform layer is able to take place following eccentric viewing training.

We propose viewing angle switchable liquid crystal display(LCD) associated with fringe-field switching (FFS) mode with high aperture ratio characteristic. This device is composed of R(red), G(green), B(blue), pixel and W(white) pixel in which R,G,B pixel shows image and white pixel for both viewing angle control and image. Conventional viewing angle controllable liquid crystal display has not transmittance because the liquid crystal only tilts up without rotates in viewing angle control region. In this paper, we suggested that the device has high transmittance characteristic because the LC directors are rotated in which viewing angle control region are generated fringe electric field.

In this research, we investigated the effect of three visual feedback conditions (direct viewing, one-monitor viewing, and tow-monitors viewing) on the task performance of human operator in teloperation task. The three different level of task difficulties under each concitions were performed by thirty-six subjects. The result of the experiments was analysed by the task difficulties, and the measurements of performance are the task completion time and the frequency of task errors. In a teleoperator, the participation of a human operator is always required, and the man-machine interface and the operator's abilities is an important issue. Recently, the different types of sensory feedback conditions(force, vision, sound, tactile, etc) for teleoperation is a very active research area in ergonomics. Among them, visual feedback conditon is an important sense that can provide the information of task environment. Therefore, the sufficient understandings and investigation for human ability under various visual feedback conditions is required to establish the efficient man-machine interface of teleoperation. The result showed that the visual feecback conditions and the level of task difficulties have a significant effect on the task performance. For three level of task difficulties, the task completion time was the shortest under the condition of direct viewing. The number of task errors under the conditions of direct viewing and two-monitors viewing were reduced by more than half compare to that of one-monitor viewing.

In this paper, we analyzed that a performing director can make effective advertising and publicity with any medium during the overall performance planning. We discovered 3 steps which are before viewing(viewing motive), during view(service quality) and after viewing(content quality) which affect purchase decision on viewing performance followed by an adjustment effect according to media type. Through surveying and analyzing the results, we confirmed that viewing motive, service quality, and content quality have significant effect on purchase decision and significant adjustment effect according to media type. Therefore, we expect that a performing director can make an effective advertising and publicity decision with any medium during performance planning.
