This paper is built upon an attempt to answer the question: "What can be done to facilitate social integration between the elderly of Bagac, Bataan and the communication students of St. Paul University Manila?" The research was designed as a qualitative inquiry that involved an outreach activity by 24 dominantly female students of Development Communication to the senior citizens of Bagac, Bataan (Philippines) and a reflection period involving the students. The students were tasked to pay special attention to the digital engagements and/or disengagements of the elderly to allow them to learn more about the difficulties and potential of using social media in development-related projects involving senior citizens. The actual two-hour encounter involved socialization between the elderly and the students. The students, prior to the encounter, were tasked to generate the funds, use them to acquire and prepare the gifts, develop the program during the actual encounter based on research-based guidelines, and photo document the entire activity. They were given guide questions for reflections a week after. The reflections were thematically analyzed and revealed that in order to facilitate greater social integration between the elderly and the communication students. The university should address the health and digital aversion issues that intensify the sense of isolation of the elderly experience daily. This can be done by enhancing the communication skills of the communication students in 16 areas.

Communication as a process of interpreting signs has always existed in people's life. In post-information society, the communication between a person and a technological system through the specific sign-attaching process becomes widespread. Moreover, it somehow replaces usual communication between people. One of the means of communication in the digital space are video games. They not only play an important role in communication processes, but also are a special case of sign-creating and interpreting. The purpose of the article is to examine video games as a space of sign-based communication between a person and a game as a specific digital system. With the help of general scientific and hermeneutic methodology, the analysis of video games as a post-information society phenomenon which people communicate to has been conducted. The process of semiosis as attaching special meanings to signs has been traced in both manipulating in-game objects and characters and understanding rules of an in-game world.

This study developed digital literacy instruments and tested their effectiveness on college students' perceptions of AI technologies. In creating a new digital literacy test tool, we reviewed the concept and scale of digital literacy based on previous studies that identified the characteristics and measurement of AI literacy. We developed 23 preliminary questions for our research instrument and used a quantitative approach to survey 318 undergraduates. After conducting exploratory and confirmatory factor analysis, we found that digital literacy in the age of AI had four ability sub-factors: critical understanding, artificial intelligence social impact recognition, artificial intelligence technology utilization, and ethical behavior. Then we tested the sub-factors' predictive powers on the perception of AI's usefulness and ease of use. The regression result shows that the most common powerful predictor of the usefulness and ease of use of AI technology was the ability to use AI technology. This finding implies that for college students, the ability to use various tools based on AI technology is an essential competency in the AI era.

The purpose of this research is to systemize the fashion digital storytelling by analyzing the communication method and its elements, and extracting the characteristics and processes of digital storytelling. Based on the previous study on the characteristics and types of storytelling the following things have been researched: 1) the process of digital storytelling in the communication process, 2) the concept and the feature of the academia of digital storytelling 3) storytelling in the document research. On the groundwork of the document research, we were able to sort out the various types, and formed a system of the features in the fashion digital storytelling cases, mainly in the four collections (Milan, Paris, London, New York) from 2000's to recent years of 2010. The types of fashion digital storytelling are episode type, narrative type, and creative type. The characteristics of each of the types are as follows. Firstly, the episode type communicates through the digital media based on the information or fact of the fashion designer brand. Secondly, narrative type communicates with the consumers using previous literature or an existing idea of the original cultural form that is rearranged in digital story expressed by the digital media. Lastly, creative type makes the designer's and consumer's susceptibility and creativity communicate through the newly made story, which expresses the unique originality of the designer. It seems that the cases and studies of using the fashion digital storytelling will increase because of its short history and lack of the case study. Fashion designer brands will show their brand image using the digital storytelling because they are able to better express originality, creativity and imagination of the fashion designer, which were factors that could not be conveyed through fashion alone.
