In this paper, we present a method to customize the ground color in outdoor sports video to provide TV viewers with a better viewing experience or subjective satisfaction. This issue, related to content personalization, is becoming critical with the advent of mobile TV and interactive TV. In outdoor sports video, such as soccer video, it is sometimes observed that the ground color is not satisfactory to viewers. In this work, the proposed algorithm is focused on customizing the ground color to deliver a better viewing experience for viewers. The algorithm comprises three modules: ground detection, shot classification, and ground color customization. We customize the ground color by considering the difference between ground colors from both input video and the target ground patch. Experimental results show that the proposed scheme offers useful tools to provide a more comfortable viewing experience and that it is amenable to real-time performance, even in a software-based implementation.

Light emitting diodes (LEDs) which can produce uniform luminescence need a very difficult and complex procedure because LEDs have strong and straight optical property. One of the major parameters for LED production is the determination of the viewing angle. However, in the present, there is still no available production technology to measure LED viewing angle and optical property. In this study, we developed a five-side LED viewing angle and optical property measurement system, having a source meter that uses a high speed switching photo relay instead of a mercury relay. This new measurement system can measure the viewing angle at a very high accuracy of ${\pm}0.66^{\circ}$. This new technology presents a great potential for fast and reliable LED mass production, which can significantly cut down the cost from savings in production time.

Animated anaglyph is the most cost-effective method for 3D stereo visualization of virtual or actual 3D geo-based data model. Unlike 3D anaglyph scene generation using paired epipolar images, the main data sets of this study is the multi-typed 3D feature model containing 3D shaped objects, DEM and satellite imagery. For this purpose, a prototype implementation for 3D animated anaglyph using OpenGL API is carried out, and virtual 3D feature modeling is performed to demonstrate the applicability of this anaglyph approach. Although 3D features are not real objects in this stage, these can be substituted with actual 3D feature model with full texture images along all facades. Currently, it is regarded as the special viewing effect within 3D GIS application domains, because just stereo 3D viewing is a part of lots of GIS functionalities or remote sensing image processing modules. Animated anaglyph process can be linked with real-time manipulation process of 3D feature model and its database attributes in real world problem. As well, this approach of feature-based 3D animated anaglyph scheme is a bridging technology to further image-based 3D animated anaglyph rendering system, portable mobile 3D stereo viewing system or auto-stereo viewing system without glasses for multi-viewers.

The purpose of this study is to investigate the causal relationship between the variables related to media sports violence viewing experience, negative emotion, aggression and violent imitation behavior of middle school students and high school students. The subjects of 240 middle school students and 240 high school students were surveyed for 2 months. Among the collected data, 64 samples judged to have low reliability were excluded from the analysis, and the final 416 data were used. The questionnaire used in this study consisted of four potential variables including experience of watching media sports violence, negative emotion, aggression, and violent imitation behavior. Among the sub-variables of experience of watching media sports violence, exogenous potential variables except frequency, period and time and questions that are endogenous potential variables were composed of a questionnaire of 5-point Likert scale. results of this study were analyzed using the AMOS statistical program, which was used to identify the causal relationship between watching media sports violence and negative emotion, aggression, and violent imitation behavior. There was no significant difference in violent imitation behavior according to school grade. The causal models for media sports violence viewing experience, negative emotions, aggression and violent imitation behavior were found to be appropriate. It was found that there was a significant causal relationship between the viewing experience of sports violence and the violent imitation behavior. Therefore, in order to reduce the imitation behavior of adolescents, it is necessary to be more careful about the production and viewing of sports violence programs at the institutions and homes that produce media.

The purpose of this study was to investigate the relationship between the performance factors of dance performance and the intention to revisit the audience, and to investigate the structural relationship between viewing satisfaction and viewing value. For data processing, SPSS Ver. 21.0 and AMOS Ver. The program of 21.0 was used. Structural relationships were analyzed using a two-step approach, and the significance of the effects was verified using bootstrapping. In addition, a full mediating effect and a partial mediating effect were presented using the three-step regression analysis mediating effect. The results of the study are as follows. First, it was found that the viewing factors influenced the viewing satisfaction and the viewing value. Second, it was found that viewing satisfaction had an intention to revisit and influenced the viewing value. It was also found that the viewing value had an effect on the intention to revisit. Third, in the relationship between the viewing factors of the dance performance and the viewing value, it was found that the viewing satisfaction had a partial mediating effect. Fourth, it was found that the attendance factor of the dance performance was not related to the intention to revisit. However, it was found that the satisfaction of viewing and the value of viewing had a complete mediating effect in relation to the viewing factors of dance performances and the intention to revisit. Through these studies, the dance performance should overcome the inherent limitations of space-time limitations and present basic data for establishing a mid- to long-term marketing strategy that can respond quickly.

The purpose of this study is to consider factors such as one's sight of viewing afar, expressional principles, and basic aesthetic category, which are treated importantly by the poets of the Joseon Dynasty era in appreciating nature. 'Afar' of the viewing afar is actual distance and aesthetic distance at the same time. Viewing afar is to find geographical features, depth, and details of a mountain, seeing the whole nature at a high place. Also, it can make possible escape from the external limitation of nature and get mental superiority and enhancement. Ultimately, viewing afar is to find out everlasting change of the nature and reason of natural creation. One's sight in viewing afar makes an appreciator's mind empty and calm, and it makes chance to harmonize human with nature. Viewing afar is to unite human nature to naturality beyond realistic value, idea, and artificiality. The mind from viewing afar has peacefulness and it is a state of serenity without any secular atmosphere. Viewing afar is an eye for beauty to leap toward an endless free state from narrow sight about objects. It rejects modification and technics in achieving an world of harmony. It means that objects should not be restrained by human's recognition. There are three expressions, which are high, horizontal, and transcendental viewing afar. The aesthetic category and beauty of peaceful mental state are realized by the expressions. The peaceful mental state makes peaceful mind from realistic conflicts and makes us experience a profound reason of nature.

Hana TV and Mega TV have been growing rapidly with IP-VOD service. The number of subscribers of both of them were 1.4 million in April 2008. Additionally, the change of viewing patterns of IPTV subscribers was predicted. Therefore, the purpose of this paper is to see how the subscribers use IP-VOD service practically. For this research, the frequency, the time and the duration of connection by genre have been analyzed on the March of 2007 and 2008. According to the result, there was a significant change quantitatively: within a year, not only the number of subscribers has doubled, but also the frequency of monthly connection has been increased 15 times. In addition, the duration of viewing per person has quadrupled. Regarding to the contents, the subscribers still prefer to watch free TV programs. However, the viewers have their own way of consuming TV programs. It has been proved that IPTV is a complementary media of free TV with a strong possibility to change the viewing patterns in the near future.

Purpose: This study aimed to compare and assess whether there was a relation between self-reported symptom and stereopsis in viewing an anaglyph 3D and a general 2D image. Methods: Seventy subjects (38 males, 32 females) were students ranging in age from 20 to 30 years. Subjects' symptoms were investigated by a questionnaire after viewing the 2D image and the anaglyph 3D image using red-green glasses for 30 minutes. Titmus circles and TNO stereopsis tests were performed before and after the images. A correlation between symptom and stereopsis was evaluated. Results: Both ocular and nonocular symptom in viewing 3D image were higher than those in 2D image. Titmus circles stereopsises using polarized filters were not changed before and after viewing images, but TNO stereopsises using color filters such as red-green glasses were increased after viewing 3D image. Ocular symptom and TNO stereopsis were increased after viewing 3D image, and there was a good correlation between them (r=0.605). Conclusions: Better stereopsises before viewing 3D are relatively lower ocular symptoms in viewing 3D image. But symptoms are increased in viewing anaglyph 3D image for a short-time and improvement of TNO steropsis is poorly associated with the relief of ocular symptoms. This tendency seems to be related with an adaptation to anaglyph 3D image with red-green glasses.

Purpose: This study was to investigate the functional improvement in peripheral vision following eccentric viewing training. Methods: 14 subjects with normal vision took a part with their right eye, peripheral retinal which is $20^{\circ}$ lateral area from the fovea was examined for contrast sensitivity(CS). Eccentric viewing training was performed for 21days with an hour image viewing and examination was repeated. Results: The critical durations for 0.7 cpd were increased 2.67(467 ms) for pre-eccentric viewing training to 2.79(616 ms) for post-eccentric viewing training (p>0.05). The critical durations for 3.0 cpd were also increased 2.53(341 ms) for pre-eccentric viewing training to 3.04(1102 ms) for post-eccentric viewing training (p>0.05). Conclusions: It is recommended to use higher spatial frequency with higher CS for eccentric viewing training and to train more frequently for a short time. Moreover, the study on Korean standardizing of the visual rehabilitation for low vision based on the etiology is sorely required.

Background: Studies suggest that induced emotional changes can affect the sensory-motor system involved in the practice of muscle activity and movement in physical aspects. Previous studies have shown focused on effects just feedback on muscle activity associated with emotions but rarely have focused induced emotional change on gross motor function such as muscle activity. Objects: The purpose of this study was to compare biceps activity and emotion that before and after viewing a video was induced positive or negative emotion. Methods: The study enrolled 34 healthy male and female who scored at normal points on the Center for Epidermiological Studies-Depression Scale. The study measured over two weeks, showing subjects pleasant and sad videos one by one in a week. We performed to measure the biceps brachii activity which is maximal voluntary isometric contraction (MVIC) and the visual analog mood scale (VAMS) scores before and after one week. The significance level was set to α = 0.05. Results: There was no significant difference in muscle activity of the biceps brachii before and after each video was viewed (p > 0.05). However, the visual analogue mood scale showed an increase in VAMS after viewing each video (p < 0.05). Conclusion: We figured out induced emotional changes are cause actual emotional changes but there are no differences in muscle activity. In this research, watching the video with a short time looks like insufficient to change muscle activity. Nevertheless, there might be different when we check various muscles with sufficient time for viewing the video. Further study is needed to measure a variety of muscles with more time for viewing the video.
