The objectives of this study was to examine the effect of Interactive Video Game on cognitive information processing the elderly. Sixty elderly were attended in this study. Their ages ranged from 65 to 70, with a mean age of 67.60 years. The subjects were randomly assigned to one of three experimental conditions: (1) interactive video game group (n=20), (2) aerobic exercise group (n=20), (3) control group (n=20). The experimental design of this study was analyzed using two-way ANOVAs with repeated measures of groups and time. Cognitive function was assessed by neuroelectrical response, and ERP analysis. The results of the study showed that the interactive video game group and aerobic exercise group showed no significant statistical differences in the response time, response accuracy, amplitude and potential of the performance of the exercise in cognitive function and ERP analysis, but improved the interaction video game group and aerobic exercise (walking) group over the control group. It was concluded that long-term aerobic exercise like interactive video game is associated with attenuation of cognitive decline in the elderly.

The purpose of this study is to present a method of Korean speaking activity utilizing mobile learning. It can compensate for the shortcomings of Korean speaking classes. Currently, speaking classes in the Korean as a foreign language site are difficult to interact individually and immediately because there are one professor and several learners. So it is hard for learners to improve their speaking ability in the actual class. However, it is helpful for learners to receive instant and individual feedback and check their pronunciation, intonation and speed. by using mobile learning. Therefore, This study consists of main-activity that can correct their pronunciation, post-activity that can make free dialogues through communication between learner and learner. So learners can improve their pronunciation accuracy and fluency as well as composition of conversation. This activity was applied to the actual class and after that, the satisfaction and opinions of learners were investigated. The results showed that many learners responded positively, but also suggested that they need to supplement mobile-learning activities in classrooms and future APP developments.

This study is aimed to classify teachers' questions and feedbacks as well as students' responses in term, of type and frequency, and speculate the distinctive features of verbal interactions including teachers' questions and feedbacks performed actively in the classes of the gifted in science. The 24 hours of the classes made for the 8th grade science-gifted students were observed and recorded. In addition, the mutual conversations between the teacher and the students were transcribed and analyzed, and the interviews with the teachers also were made. It is found that the teachers usually use the question methods of memory recollection, perception and memorization, together with an instant feedback method, while the students prefer to respond with rather short answers. The characteristic features of the class by the teachers who lead the active class show that they use the open questions at the beginning, raise the level of the questioning, use the questions 'why and how' frequently, and to ask evaluative questions. Their feedbacks to the students interestingly indicate that they show the students the attitude of accepting and receiving students' replies, invite different responses from other students by reserving instant answers or judgements to the students, and give the students the confidence of solving the next problems, by praising and encouraging them.

Recently, with the expansion of the use of cross media, the public is not just watching the broadcast, but is also consuming various information about actor, stories, products, etc. that appears during the broadcast. However, the devices used for viewing and the devices used for searching are different, which is inconveniences, and due to the differences between the point in time when the desired information is provided through the search, the public has difficulty in obtaining detailed information of the target product after encountering product placement advertisement. In addition, it is difficult for advertisers to confirm the effect of product placement advertising through the reaction of viewers who have encountered product placement advertising. In this paper, we intend to propose an interactive streaming platform that supports the instant retrieval of product information to users by including product placement advertisement information in broadcasting. Through this, viewers can quickly receive detailed information of products on the screen by giving an event when a product of interest comes out while watching the broadcast, and advertisers can check the effectiveness of product placement advertisements by receiving interactive responses from viewers.
