The convergence of education and technology has been emphasized, leading to the application of educational technology (EdTech) in the field of education. EdTech provides learner-centered, customized learning environments through various media and learning situations. In this paper, we designed hardware for EdTech-based educational tools for IoT security education in the field of cybersecurity education. The hardware is based on a dual microcontroller unit (MCU) within a single board, allowing for both attack and defense to be performed. To leverage various sensors in the Internet of Things (IoT), the hardware is modularly designed. From an educational perspective, utilizing EdTech in cybersecurity education enhances engagement by incorporating tangible physical teaching aids. The proposed research suggests that the design of IoT security education hardware can serve as a reference for simplifying the creation of a security education environment for embedded hardware, software, sensor networks, and other areas that are challenging to address in traditional education..

As a variety of HMD(Head Mounted Display) has come out, the production of 3D images onto which VR(Virtual Reality) technologies are grafted has been contributed to activating the production of image contents depending on a tangible or immersing type. VR-based image contents have enlarged their applicability across the entertainment industry from animation and game to realistic images. At the same time, the solution development for producing VR image contents has also gained elasticity. However, among those production solutions which have been used until now, fixed stereo camera based photographing has a limit that the binocular disparity of a user is fixed. This does not only restrict a way of expression a producer intends to direct, but also may cause the effect of 3D or space not to be sensed enough as view condition is not considered enough in a user's side. This study is aimed at resolving with skills applying in the latter part of 3D image production the problem that convergence points may be adjusted with restriction, which tends to happen at the time of the production of VR image contents. The later stage of the 3D imaging work analyzes and applies to game engines the significance of adjusting convergence points through the visualization of binocular disparity so that it is available to implement a function that the points could be controlled at random by a user.

This study, centered on the artworks of Julius von Bismarck and Hito Steyerl, elucidates the aesthetic role that fashion plays in Berlin's contemporary art as an art medium. To this end, the following research questions are addressed: What are the characteristics of Berlin's contemporary art and contemporary fashion? What are the artistic styles and features of Julius von Bismarck and Hito Steyerl, and what attributes of fashion as an artistic medium are embedded in their works? How can the attributes of fashion, leveraged as an artistic medium in Berlin's contemporary art, be identified? The research methodologies used in this study include literature review, content analysis, and case analysis. The analytical findings of this study reveal that 1) Berlin has established itself as an international center of culture, yielding keen insights into artistry with reflections on technological media, and 2) the contemporary artworks of Julius von Bismarck and Hito Steyerl in Berlin feature some significant attributes of fashion as an art medium such as contemporary antisociality, metaphorical theatricality, and the tangible and intangible properties of algorithms.
