This study is conducted to create an origami torus kinetic installation that rotates infinitely on its circular axis produced by generative algorithms and mechanical devices. The act of folding and unfolding the piece of paper is intended to evoke images of flowers blooming and fading, representing the theme of the cycle of life. Origami has been used in a variety of fields due to its ease of creating a three-dimensional form from plane and its sculptural qualities of being able to shrink, expand, and reconstruct. However, most cases of movable folding structures are often limited in motion to repeating simple opening and closing. To produce seamless, continuous folding and unfolding movement, the origami structure requires to have a toroidal form in certain origami patterns and mechanical assistance. This paper investigates the examples of kinetic origami installations, the principles of origami tessellation, and generative design tools to develop blueprint of generative algorithm for creating a suitable map for forming an annular folding structure that can rotate in a circular axis. This study focuses on Miura-ori and accordion folding among origami tessellations and explores generative design tools and algorithms that can create and simulate these origami drawings. The final Blueprint is based on an accordion fold and allows you to adjust various parameters such as the number of sides, length, and angle of the fold. The end of the paper introduces the application of the simulation by devising mechanical structure to realize its circular motion of origami torus. The proposed algorithm does not consider all the laws of physics and the properties of materials, so it has a limit of accuracy. However, no major problems were found during the actual fabrication process, and the rotation of the structure was performed as simulated. The results of the study can be used for simulating and physically creating various shapes of rotating origami torus.

Digi-log is a term to describe user interfaces that utilize both digital and analogue modalities in conjunction. These two elements complement each other to provide the most optimal user experience. The most representative case is smartphones with home buttons. However, many manufacturers have removed home buttons from smartphones. This research analyses the impact of the presence, or absence, of analog interfaces in the context of mobile devices. An experime nt was conducted to investigate the usability and user psychological satisfaction from using home buttons, where the deployed prototypes were classified in terms of triggers and feedback type. The generational difference amongst users and accumulated experi ence of using digital digital-only smartphones was also consi considered. Results confirm that analog interfaces have a positive effect on users’ usability and psychology. This is because Experiment Case A, a type of analog home button, was the most positive in Adequacy, Efficiency, Consistent, Comfort and Satisfaction, w which are user experience evaluation factors. Furthermore, it was confirmed that the difference between Ca se A and other cases was significant. (p<0.05) In generation differences, experience of using the digital digital-only mobile phones in the younger generation did not affect usability. This is because, in the result of the 2 2-wayway-ANOVA about usability measurement, Gen X and Z were p>0.05 on the Adequacy, Effici ency, and Consistent, which are usability factors in the user experience. However However, it did have a statist statistically significant effect on their psychology. In the older age group, experience with digital digital-only smartphone affected both usability and psychology. Th is is because all generation had a significant impact on user psychology in the results of 3-wayway-ANOVAANOVA. (p< In additio addition, in the result of 2-wayway-ANOVA relevant to usability factors , Gen X was p<0.05 0.05. This research concludes that analog interfaces p ositively affect user experience, and therefore needs to be considered if device manufactures are to accomm accommodate the needs of multiple generations through a more inclusive design.

In 2022, North Korea officially introduced Kim Ju-ae, the daughter of Kim Jong-un, through the reporting photographs of the Chosun Joongan Tongsin and the Rodong Sinmun. North Korea has institutionalized the hereditary succession through the “Mount Baekdu Bloodline” in accordance with the “Ten Principles for Establishing the Monolithic Ideological System.” Therefore, the appearance of Kim Ju-ae may be seen as a strategic move in preparation for the fourth-generation succession following Kim Jong-un. North Korean domestic and international media outlets, including the Rodong Sinmun and the Chosun Joongan Tongsin, have deliberately portrayed Kim Ju-ae by reporting on her participation in 15 strategic weapon inspections and military events, among other activities. Such portrayals evoke the concept of the "Theatre State" proposed by Clifford Geertz, symbolizing the entire nation as a unified organism and an expanded family with biological Bloodline, which serves as a propaganda strategy to legitimize the continuation of the Mount Baekdu Bloodline as the absolute authority in the post-Kim Jong-un era. In this context, this study is based on the theoretical background of the Mount Baekdu Bloodline and the Theatre State and aims to visually analyze the reported photographs of Kim Ju-ae in the Chosun Joongan Tongsin and the Rodong Sinmun. To achieve this, we selected 40 close-up photographs from the original 95 reported photographs of Kim Ju-ae and conducted visual data analysis using Google’s Vertex AI Vision, a pre-trained machine learning and operations tool (MLOps). The analysis revealed that emotions of joy and neutrality were each represented in half of the observed photographs of Kim Ju-ae's public appearances. This suggests that the photo staging or selection strategy for Kim Ju-ae discerns between expressions associated with private familial interactions with her father and those intended for public presentation to the populace. Her expressions towards her father convey a familial warmth indicative of socialist familialism, while her public expressions are more serious and leader-like, selectively exhibiting joy and neutrality. Hence, this study interprets the portrayal of Kim Ju-ae in the 15 reported instances through Vertex AI Vision analysis as revealing a leader's image that is both amiable and assertive of biological lineage, potentially signifying a deliberate propagandistic orchestration for future succession. This research could transcend the limitations of subjective analysis by experts on North Korea's succession, providing objective data through next-generation artificial intelligence technology.

Local regeneration or local content creation, in contrast to large-scale urban regeneration projects, must grow based on favorable relationships with local residents and continuous communication. This study focuses on the activation of neglected alleyways near universities, emphasizing the essential role of introducing strategic branding methodologies in local revitalization, as demonstrated through empirical case analysis and phenomenological examination. The ultimate goal is to understand that the activation of Seopgol Street, primarily inhabited by Hongik University Sejong Campus students, requires prior establishment of a new local identity and image as a brand. Recognizing the importance of psychological attachment and a sense of belonging in this process, a systematic branding approach was introduced and implemented. Interviews with various stakeholders, including local residents, local creators, and officials such as the deputy mayor and director of the economic industry department of Sejong City, revealed that branding methodologies not only serve as catalysts for the revitalization of neglected areas but also contribute to sustainable development.
