Depending heavily on CG technologies, the movies with CG generated characters and backgrounds focus on the reality effect in terms of the graphic itself. However, reality effect means a lot more in filmmaking than just pictorial representation. This study analyzes shot-by-shot a sample movie which has good staging as a part of film directing to increase reality effect in terms of diegesis and a film as a whole not just pictorial reality effect.

Due to the rapid development of computer and digital technologies, those technologies were used in advertising. In order to meet the needs of marketing, a virtual space or character using 3D graphic augmented reality technology was developed and applied to advertisement. This study analyzed the characteristics of augmented reality in terms of interface design and spatial expression of augmented reality through case study. Firstly, we wanted to find the relationship between the types of the augmented reality advertisement and interface effects. Secondly, we wanted to find the spatial expression methods. The sample survey case studies based on 42 articles from 2012 to 2018 using Chinese and Korean site sharing augmented reality advertisement. The results of the case studies were divided into two parts. Firstly, the relationship between augmented reality types and interface effects were found basing on the augmented reality index. It means that the augmented reality index can be illustrated by using the augmented reality type. Simultaneously, the augmented reality type can be illustrated using the interface effect. The second part was that the types of display were used as a spatial representation. And the results showed that mobile display and public place display were the most frequently used.

With the technology of the 4th Industrial Revolution integrated into the industry as a whole, digital transformation (DT) is becoming an innovative and essential element of corporate survival in the fashion industry, and it is expected that the paradigm shift in shopping will become an unavoidable reality, especially based on the AR. Therefore, in this study, the characteristics of augmented reality were presented separately as perceived realism, interaction, pleasure, and usability, and the influence of augmented reality by immersion parameters on the user's satisfaction and intended to reveal the relationship between satisfaction and usage through the characteristics of augmented reality. For the purpose of this study, a structured questionnaire was conducted, and the available 209 responses were collected and used for empirical analysis. The results of the empirical analysis are as follows. First, while immersion has the greatest effect on satisfaction, the effect on use intention has a stronger effect on satisfaction than immersion. This indicates that purchase occurs when the user's immersion leads to satisfaction, and when the satisfaction falls, the intention to use is also lowered. Second, interactivity, enjoyment, and ease of use among the various characteristics of fashion applications have a positive effect on immersion. Among them, ease of use had a strong effect on immersion. In light of this, it can be seen that ease of use should be considered first when creating an application based on augmented reality in the future fashion industry. However, the perceived reality is low in the degree of immersion, and the effect on satisfaction is also lowered, so it is difficult to be connected to intention. Considering that this study was conducted through indirect experience through video viewing, this study expects the development of research through a more practical research model in the future, as the impact is considered to be a relatively low measurement.

Classic cultivation theory and research has been noted for its failure to capture subtle variation in effects by genre and to consider tangible and practical dependent variables. Redressing these limitations, this study aimed at extending cultivation theory frame to incorporating fatalistic attitudes and reality television viewing, especially with the mediator of perceived realism. We first replicated the original cultivation effect by showing the significant effect of overall TV viewing. Even controlling for overall TV viewing, reality-based program use showed positive association with fatalistic beliefs; furthermore, the effect remained significant, additionally controlling for news(fact) use and drama(fiction) use. In a nutshell, the cultivation effect of reality-based TV program on fatalistic beliefs turns out quite stable even after controlling other competing genres.

The purpose of this study was to investigate the effect of integrated teaching and learning method using augmented reality for effective promotion of child - friendly attitude and environmental preservation attitude and explored its applicability. For this purpose, based on the augmented reality fairy tale, we designed an experience - oriented integrated teaching and learning method such as reading book, story - telling, drawing, environmental conservation practice activity. The experimental group was divided into two groups: augmented reality reading fairy tales (A) and children's book reading fairy tales (B). First, interest, immersion, and empathy were higher in the application environment of integrated learning teaching method based on Augmented Reality. Second, there was no difference between the two groups in content understanding. Third, in terms of expressiveness, it was verified that various expressions were expressed in the applying environment of the integrated teaching - learning method based on augmented reality through drawing activities. Fourth, in practice activities, more students were practicing in the augmented reality - based integrated teaching - learning method applied environment, and the number of practice activities of individual students was also confirmed. This study suggests that the application of the integrated teaching and learning method can enhance the effect of education when using the smart teaching media using the augmented reality in early childhood education.

Purpose : The aims of this study was to conduct a systematic literature review with meta-analysis to investigate the effect of virtual reality based rehabilitation program on balance of patient with stroke in Korean studies. Method : The studies for analysis were searched in electronic databases(Research Information Sharing Service; RISS, Korean Studies Information Service; KISS, DBpia, e-articles, National Assembly Library). The key words for search were 'virtual reality', 'stroke', and 'balance' and only randomized controlled trials and clinical controlled trials were included. Of 40 studies identified in the search, 20 studies met the criteria of this study and included in this meta-analysis. Result : The results were as follows: 1) The overall effect size of virtual reality based rehabilitation program was 0.557(95% critical interval; 0.340~0.774). 2) In the analysis of sub-categorical variables, effect size was as follows; the commercial game type(0.621) > virtual environment type(0.335); the dynamic balance measurement(0.750) > static balance measurement(0.226); randomized controlled trial(0.653) > clinical controlled trial(0.275); and thesis type(0.706) > article of journal type(0.339). 3) In the analysis of sub-continuous variables, as time of program(per session) increased, the balance increased(p<0.05). Conclusion : The results of this study showed that virtual reality based rehabilitation program moderately improves the balance of stroke patient. Further studies are recommended to investigate the effect of sub-variables related to virtual reality programs on motor functions of patient with stroke.
