본 연구는 한류 확산의 진원지이자 한국 드라마 수출의 주요국인 일본을 대상으로 일본 시청자들의 한국 드라마 시청과 한국에 대한 태도 형성 관계를 고찰하고자 하였다. 한국과 일본은 과거 지배-피지배라는 역사적 특수성을 가지고 있는바, 일본 시청자들의 한일 역사 인식에 따른 한국 드라마 시청성과의 관계를 살펴보았다. 한국 드라마 주시청자층인 일본 여성 10~60대 250명을 대상으로 현지 서베이를 실시한 결과, 긍정적인 한일 역사 인식은 한국 드라마 시청의 높은 몰입행위를 나타냈고, 높은 몰입행위는 전체적인 한국 드라마 평가와 한국에 대한 태도에 긍정적인 영향을 미치는 것으로 나타났다. 한일 역사 인식이 한국 드라마 수용의 주요 영향 요인임을 밝힌 연구결과는 발전적인 한국 드라마 유통을 위해 일본 시청자의 왜곡 없는 한일 역사 인식이 선행되어야 하며, 이를 위한 상호 문화외교적 정책방안이 재고되어야 함을 시사하는 것이다.

본 연구는 종합뉴스 채널인 KBS, JTBC, YTN를 대상으로 뉴스의 앵커 평판과 브랜드 자산 평가가 뉴스의 지속적 시청 의도에 어떤 영향을 미치는지를 검증하였다. 자료 수집은 각 채널별 뉴스를 시청하고 있는 전국 성인남녀 539명을 대상으로 하였으며, 앵커 평판과 뉴스 브랜드 자산 평가 요인의 영향력을 분석하기 위해 위계적 회귀분석을 실시하였다. 연구 결과, 첫째, KBS는 남성, 저학력, 보수 성향, 시청 빈도가 높을수록, 앵커 인지도와 뉴스 인지도, 뉴스 선호도가 높을수록 뉴스를 지속적으로 시청할 것으로 나타났다. 둘째, JTBC는 진보 성향, 시청 빈도가 높고, 앵커 신뢰도와 뉴스 인지도, 뉴스 선호도, 뉴스 품질에 대한 평가가 높을수록 뉴스를 지속적으로 시청할 것으로 확인되었다. 셋째, YTN은 시청 빈도가 높고, 앵커 신뢰도와 매력도, 뉴스 선호도와 품질에 대한 평가가 높을수록 뉴스를 지속적으로 시청할 것으로 확인되었다. 본 연구는 '뉴스 브랜드 자산'이라는 개념을 정립하였으며, 지상파TV와 종합편성채널, 보도전문채널을 대상으로 앵커 평판과 뉴스 브랜드 자산의 영향력을 평가한 최초의 연구라는 학술적 의미가 있다.

A field-sequential color projection system can display color images using panel. However, it suffers from a characteristic trichromatic separation known as "color breakup". The viewing of images exhibiting color breakup may cause visual fatigue and mental stress. In this study, the authors examine, from the standpoint of human factors, the objective and subjective symptoms that can result from the viewing of images with color breakup.

As the speed of networks that subscribers can use has greatly increased, demand for high-quality broadcast content, such as from Internet Protocol Television (IPTV) and Video on Demand (VoD), is likewise increasing. Therefore, while broadcasters are increasing content and channels, they are striving to improve consumer quality of experience (QoE) to differentiate themselves from competitors, including by producing higher physical-quality content. Recently, subjective measurement methods have been internationally standardized as the most reliable approach for measuring and evaluating IPTV QoE. However, a majority of these methods are performed in experimental environments and are based on the extremely brief viewing period of approximately ten seconds using original reference videos. It is actually difficult to apply standard evaluation methods based on a ten-second viewing interval to assess real broadcast watching of IPTV or other services that involve a longer time (i.e., more than thirty minutes). In this paper, we therefore propose a method that accommodates actual viewing environments. Using the mean opinion score, we experimentally analyze the effects of evaluation interval changes under actual conditions in which IPTV service is provided. In addition, we propose improvements by applying the results into actual live broadcast IPTV service and by analyzing consumer service QoE.

In the full white pattern, white uniformity means the degree of uniform distribution of white color and luminance across the whole screen. Among the FPDs(Flat Panel Displays), the TFT-LCD has weak point of viewing angle. The viewing angle considering location and direction can cause different image quality of the TFT-LCD. Therefore, white uniformity of the TFT-LCD must consider viewing angle. Based on international standards, this study proposes an alternative that is realistic and ergonomic measurement of white uniformity of the TFT-LCD.

Conventional stereoscopic (3D) displays using binocular parallax generate unnatural conflicts between convergence and accommodation. These conflicts can affect the observer's ability to fuse binocular images and may cause visual fatigue. In this study, time series changes in visual fatigue and depth sensation when viewing stereoscopic images with changing parallax were examined. In particular, the physiological changes, including the subjective symptoms of visual fatigue, when viewing five parallax conditions, were examined. Then a comparative analysis of the 2D and 3D conditions was performed based on the visual function. To obtain data regarding the visual function, the time series changes in the spontaneous-blinking rate before and during the viewing of 3D images were measured. The time series change results suggest that 2D and 3D images cause significantly different types of visual fatigue over the range of binocular disparity.

목적: 2D와 3D 영상 시청에서 나타나는 시각반응의 변화를 측정하고 평가하고자 하였다. 방법: 시기능이 정상인만 19세 이상 25세 이하의 대학생 44명을 대상으로 하였다. CA/C비(convergence accommodation/convergence ratio), 폭주로 유도되는 PD(interpupillary distance)변화와 조절반응, 3D 영상 시청 시 자각적 인지거리를 측정하였다. 결과: 폭주와 조절은 2D 영상 시청보다 3D 영상 시청에서 더 컸으며(p<0.05), CA/C비와 조절반응은 양적 상관관계(r = 0.477, p = 0.001)를 보였다. PD가 작을수록 심도지각의 깊이는 큰 것으로 나타났으며, 3D 영상에서 폭주는 인지하고 있는 거리에서의 폭주보다 더 큰 것으로 나타났다. 결론: CA/C비가 클수록, PD가 작을수록 3D 영상 시청에서 시각적 불편함은 더 심할 것으로 예상된다.

Steps are very common features in our living environment. Unfortunately, the occurrence of accidents on steps is thus inevitable. A failed visibility to recognize a step remains the most common attribute in these accidents. In this research, sensory scales of step visibility were created in order to examine the effects of two factors on step visibility in sensory testing methods; observation height from floor and eye condition while viewing a step from the descending direction. Results of sensory tests revealed strong influence of eye condition on step visibility. Influence of visual characteristics of each step was also examined and clarified.

Objective: This study is conducted on the differences between flat and curved displays with respect to location of focused points, posture and satisfaction as well as preferred tilt angles. Background: In order to avoid physical and eye fatigue caused by misplayed sitting posture, many studies have asserted that the display requires appropriate location, size and tilt angle as well as curvature. However, most studies have focused on the work environment and the results are varied in the extent. Method: Eye height data in sitting posture were collected from 30 participants. Participants selected the most comfortable viewing angle within the range from $0^{\circ}$ to $12^{\circ}$ while watching videos for both curved and flat display. Then, physical and eye fatigue and overall satisfaction were subjectively evaluated. Lateral diagram describing viewing display condition was set and used to develop linear models for expecting the preferred tilt angle. Results: Due to sitting in the natural viewing posture rather than upright, the eye height is lowered to about 4.6 centimeters, on average, for both displays showing no significant differences. In contrast, preferred angles for the two displays are significantly different and this can be interpreted that curvature vary the points focused. Two linear models as functions of sitting eye height are developed to expect preferred tilt angle for each display. Based on the result of overall satisfaction evaluation, curved display is statistically better than flat display. Conclusion: The results show that flat and curved displays are significantly different expect for the viewing posture. However, reasons for preferring curved display are not accurately factorized and the linear models are limited in the experiment condition such as size of display, distance between display and viewer and other physical environmental factors. Further studies on curved displays under more various conditions are required. Application: This study can contribute to use of the curved display in various way.

In this study, the effect of augmented reality subtitle content on users was investigated by using a subjective evaluation method and a statistical approach. The human factor was defined as subtitle position and font size. Then, we analyzed the effects of the defined factors on human eye comfort and visibility. Ten participants conducted related survey evaluation tasks with a 1-minute break after viewing the content for 3 minutes.
