In this paper, we introduced design of intelligent surveillance camera system and typical event processing scenario for urban transit. To analyze video, we studied events that frequently occur in surveillance camera system. Event processing scenario is designed for seven representative situations(designated area intrusion, object abandon, object removal in designated area, object tracking, loitering and congestion measurement) in urban transit. Our system is optimized for low hardware complexity, real time processing and scenario dependent solution.

This study aimed to examine an augmented reality-based teaching simulation in a mobile application. We examined how AR-enabled interactions affect users' perceived scenario usefulness and avatar realism. The participants were forty-six undergraduate students. We randomly grouped them into two conditions: AR and Non-interactive video groups with equal sample sizes. This study employed an experimental design approach with a one-way multivariate analysis of variance with repeated measures. The independent variable is the presence/absence of AR interaction with a mobile application. The dependent variables were avatar realism and scenario usefulness. The measures explored how the student avatar's emotional intensity in a scenario influences user perception. The results showed that participants in the AR-interaction group perceived avatar realism significantly higher than those in the non-interactive video group. Also, participants perceived the high emotional intensity scenario (aggression toward peers) to be significantly higher usefulness than the low emotional intensity scenario (classroom disruption).

The fusion of virtual and reality and the revolution of gamification are beginning in human culture. As the quaternary industrial revolution enters the era, major developments of convergence main content games are expected as human-made play products. Now that we need a diverse game IP, we need a methodology that makes it easy to approach game scenario creation. The creation of the game scenario has a very large difference due to interactivity with the general video scenario. Therefore, without interactive knowledge, it is difficult to challenge game scenario creation. In this paper, 'Game Scenario Creation List' was created in order to lower the barriers to entering game scenario creation. I hope that this paper will be even a little positive for the development of game contents.

Purpose: This study was done to develop a video discharge education program focusing on mother-infant interaction to facilitate the development of maternal role confidence for mothers of premature infants. Methods: The process of the program was based on the Network-based Instructional System Design suggested by Jung (1999). For the content of the program, needs and concerns of mothers of premature infants found on web sites and existing literature were analyzed. Based on this content, the scenario and the video were developed. Nurses and mothers of premature infants participated in the process of testing the content validity, scenario development, and evaluation of final video production. The final video has two parts and lasts 21 minutes. The first part focuses on mother-premature infant interaction and the second part focuses on health management of infants. Results: Eleven mothers of premature infants participated in the evaluation of the appropriateness of the video as a teaching method and for educational content. They reported that the content on mother-infant interaction, maternal sensitivity, and maternal role confidence was especially beneficial. Conclusion: The findings indicate that video program is effective for education on maternal-premature infant interaction and the use of video in practical settings is strongly recommended.

This study aimed to identify whether or not four service situations varying according to positive and negative combinations of physical evidence and functional service influence store image and purchase behavioral intentions of customers at bulgogi restaurants. The video-scenario technique was used for the study. Data were analyzed with the SPSS (Window 19.0) package using frequency analysis, one-way ANOVA, 2 by 2 factorial ANOVA, exploratory factor analysis, and multiple regression analysis to confirm the hypotheses. The combined effect of functional service and physical evidence influenced store image and purchase intention. In terms of seperate effect of physical evidence and functional service, the effect of employee service on store image was more powerful than that of physical evidence, even though the effect differed depending on the situation. Purchase intention was only influenced by functional service quality from employees under the four different scenarios. Thus, when opening a Korean restaurant, proper management of tangible evidence suitable to service, and the prices expected from local customers should be determined. Additionally, extremely high or low levels of physical evidence management should be avoided.

While the society becomes older, the quality growth on the service adequate to seniors is required. The service design is highlighted as a measure to improve the quality of service. And actually, success cases through the service design in various areas are globally introduced. In this study, a research is conducted to develop a service scenario to expand seniors' communication by applying the service design methodology. To analyze seniors' behaviors related to the communication, profiles are established by performing interviews with professionals and the qualitative survey to seniors. And based on the profiles, an idea workshop is conducted with multi-disciplinary experts to develop ideas for seniors' communication. The representative service is drawn by refining ideas. And the detailed service scenario and the video prototype are developed by concentrating one service scenario. The developed service scenario is anticipated to be utilized as a base material to develop services to expand seniors' communication in the future.

A visual novel, a type of digital content combining novel and game, was designed as hypermedia which includes various media, for instance, image, sound, and video. The narrative of visual novel contains multimedia elements and highlights multi-scenario structures based on hypertext. Prior to creating visual novel scenario, a writer should thoroughly consider two main points. First of all, the scenario should cover the multimedia features of visual novel. Secondly, the scenario should be structured as a multi-scenario providing with performativity to players for interaction with readers. This study examines the influence of changes in platforms on visual novel scenario adjusted to mobile environment. It would provide an opportunity to understand how storytelling changes and adapts to rapid transformation of digital media contents.

The application of video processing techniques are useful for the safety of nuclear power plants by tracking the people online on video to estimate the dose received by staff during work in nuclear plants. Nuclear reactors remotely visually controlled to evaluate the plant's condition using video processing techniques. Internal reactor components should be frequently inspected but in current scenario however involves human technicians, who review inspection videos and identify the costly, time-consuming and subjective cracks on metallic surfaces of underwater components. In case, if any frame of the inspection video degraded/corrupted/missed due to noise or any other factor, then it may cause serious safety issue. The problem of missing/degraded/corrupted video frame estimation is a challenging problem till date. In this paper a systematic literature review on video processing techniques is carried out, to perform their suitability analysis for NPP applications. The limitation of existing approaches are also identified along with a roadmap to overcome these limitations.
