The study considers the meaning of the composite images created when users capture present images over past images tagged location data in using the mobile augmented reality technology. The composite image through the location-based augmented reality technology is the result of matching the same location data between present images users are capturing and past images captured already. It is the new composite images that contain two different narratives-current and past in the same space and in real-time. We developed the mobile application implemented augmented reality technology and analysed the process that users create multi-layered narrative in the middle of capturing present image through augmented reality module. In addition, through the comparison with similar studies and applications of the augmented reality, we found that the key to give the multi-narrative in the composite images is the user's participation to put its personal intentions in real-time capturing process. In further development, we'll be able to utilize the application in order that users easily create multi-layered narrative composite image using cultural and personal records.

It is widely agreed that a documentation strategy that considers the social context of fragmented records is needed for documentation of social memories. This paper examined a new methodology named Seoul Narrative Archiving Policy(S-NAP) which was developed for the documentation of social memories in metropolitan areas. Also, the paper reviewed the applicability of S-NAP through the collection cases of Seoul Metropolitan Archives. The development process of the S-NAP is as follows. First, acquisition topic domains that cover an entire metropolitan region were developed. Next, implementation units(S-NAP) were designed through extensive data analysis that encompasses social, economic, culture, and art areas and reflects outcomes of regional studies. As a result, a total of nine acquisition topic domains, 61 parents S-NAP, and 184 children S-NAP were derived from the aforementioned methodology and methods. Finally, this paper proposed the applicability of S-NAP as archival contents and as a supportive tool for archival activity networks.

In this paper, we divided domestic and foreign digital cultural activation policies into four types. We also described projects of each policy and analyzed the limitations of the policy. Finally, we suggested solutions to overcome these limitations. Changes in daily life caused by the recent development of 5G network technology, augmented reality, and virtual reality technology have brought many changes in the way of preservation and utilization of cultural heritage. In particular, digital technology is used for digitization of cultural heritage, storing, and managing digital data, digitally restoring cultural heritage, and enabling time, space, multi-sensory experiences. For this purpose, new policies was required to utilize this. This study divides domestic and international digital heritage policies into digital infrastructure construction, sharing and communication platform construction, public relations, and demonstration contents production support policies. This study is meaningful in classifying the fields of digital heritage policy and introducing digital heritage policy trends. It is also meaningful to suggest ways to improve digital heritage policies through analysis of domestic and foreign cases.

Jeju City is one of the cities where decline of old city-center is appearing due to the reduction of residential and floating population. The decline of old city-center of Jeju City has been on the rise since the 1990s, and has been intensifying in the 2000s. Jeju City is currently activating specific policies to ensure activation and diversification of the local commercial area. In this paper, we propose a new method to increase the number of visitors to Jeju-Mokkwana by using Augmented Reality technology for activating commerce of old city-center. Various Augmented Reality contents based on smart-phone are implemented and operated in Jeju-Mokkwana. Also the survey is conducted to 574 visitors who have experienced online/offline promotion for analyzing effects. Survey results show that the proposed method can be effectively used to activate the old city-center by increasing the floating population.

The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.
