In this paper, we propose gesture recognition based 3D Serious Games to prevent dementia. These games are designed to enhance the effect of preventing dementia by helping increase brain usage and physical activities of users by the entire body gesture recognition. The existing cameras used for gesture recognition technology are limited in terms of recognition ratio and operation range. For more stable recognition of the body gestures, we recognized users with a 3D depth camera, obtained joint data of users, and analyzed joint motions to recognize gestures of the body. Game contents were designed to practice memory, reasoning, calculation, and spatial recognition focusing on the atrophy of brain cells as a major cause of dementia. Game results of each user were saved and analyzed to measure how their recognition skills improved.

The purpose of this study was to develop and to explore the possibility of the virtual reality based communication training program(VR-CTP) for students with intellectual disabilities. To do this, sentences and dialogue of program were extracted from the National Common Basic Curriculum of Special School and the contents design of program were developed based on the consultation by special education experts. To explore the possibility of applying the VR-CTP, a usability evaluation was conducted with 30 special school teachers and 44 students with intellectual disabilities. The results showed that the VR-CTP had a high level of usability as the special school teachers received 4.23 and the students with intellectual disabilities received 4.44 out of 5. But there is no difference of usability evaluation on the special teachers' school level and teaching experiences without arrangement of school. Also, there is no difference of usability evaluation on the students' IQ, school level, and arrangement of school. As a result of this study, we can draw a conclusion that there is a possibility of applying the VR-CTP to language education for students with intellectual disabilities.

In strong dramas, pot, character, and theme, three basic elements in dramatic structure, are effectively integrated forwards the same dramatic idea. Plot might be considered as the most important element to combine events and character. However, at some point of the script, the writer becomes less interested in the mechanics of the plot, and the characters take over, because audiences remember the characters or the situations more clearly than the plot. Therefore, the workshop of dramatic structure would be successful when it starts from excogitating the character and the situation, by improvising 'voices' of characters, building 'back story', and reconstructing 'outline from the antagonist's view'. With these exercises, the writer and the director understand the mechanics of dramatic plotting by characterization, which include the choice of the protagonist, and the description of plausible actions and the theme, and they consequentially find the way to obtain solidity and plausibility in the scenes.

In the outwardly changing environment of public security these days, police administration faces the nation's request for qualitative improvement of police service and the new request of police reformation for changing function of police in Korea. The nation wishes police to provide service fairly. The issue most seriously mentioned in the reliability of police service is very large gap in the recognition of service quality between supplier and consumer. To get the trust of nation in delivering police service, the police must have justness, consistency, punctuality of delivery, propriety and efficiency. However, the recognition of citizen, the consumer of police service is more important. How to correspond to the nation's request to police needs to be decided by evaluating the quality of present police service. It is necessary to be interested in what customer wants so as to evaluate the quality of police activity.

In this paper, we present a FAES(a Facial Animation with Emotion and Speech) system for speech-driven face animation with emotions. We animate face cartoons not only from input speech, but also based on emotions derived from speech signal. And also our system can ensure smooth transitions and exact representation in animation. To do this, after collecting the training data, we have made the database using SVM(Support Vector Machine) to recognize four different categories of emotions: neutral, dislike, fear and surprise. So that, we can make the system for speech-driven animation with emotions. Also, we trained on Korean young person and focused on only Korean emotional face expressions. Experimental results of our system demonstrate that more emotional areas expanded and the accuracies of the emotional recognition and the continuous speech recognition are respectively increased 7% and 5% more compared with the previous method.

Due to the recent increase in information encountered on social media, algorithm-based recommendation formats selectively provide information based on user information, which often causes a filter bubble effect by an Echo Chamber. Eco-chamber refers to a phenomenon in which beliefs are amplified or strengthened by communication only in an enclosed system, and filter bubbles refer to a phenomenon in which information providers provide customized information according to users' interests, and users encounter only filtered information. The purpose of this study is to propose a method of efficiently selecting information as a way to improve the filter bubble phenomenon by such an echo chamber. The research progress method analyzed recommended algorithms used on YouTube, Facebook and Amazon. In this study, humanities solutions such as training critical thinking skills of social media users and strengthening objective ethical standards according to self-preservation laws, and technical solutions of model-based cooperative filtering or cross-recommendation methods were presented. As a result, recommended algorithms should continue to supplement technology and develop new techniques, and humanities should make efforts to overcome cognitive dissonance and prevent users from falling into confirmation bias through critical thinking training and political communication education.

This study was conducted so as to examine which change tDCS (Transcranial Direct Current Stimulation) for improving working memory can make on the EEC of stroke patients. Among the patients who suffered for more than 6 months by hemiparalysis caused by stroke, 20 patients selected by MMSE and DST were randomly divided into I group (10 patients) fulfilled by only CCT and II group (10 patients) fulfilled by both tDCS and CCT for total 4 weeks, 30 minutes per a day, three times per a week. For examining EEC variation, the absolute spectrum power was calculated by three bands (${\theta}$; 4~8 Hz, lower ${\alpha}$; 8~10.5 Hz, upper ${\alpha}$;10.5~13 Hz) during the task of words, photos and mental calculation with EEC test, before the arbitration, after 2 weeks and after 4 weeks, so the rate of increase and decrease (%) for the reference EEC was obtained. As the results, the first, particular aspects different one another in three bands were detected according to the measuring period and task. The second, in the forth week, there was only a significant difference in lower ${\alpha}$-power of all tasks. Therefore, through the procedure measuring EEC of this study, the degree of working memory's damage can be expressed by numerical value and tDCS should be additionally helpful for brain damaged patients' perception rehabilitation.
