This paper is a study on the digitization of an analog 3D pen. The term digital implies features such as homeostasis, transformability, combinability, reproducibility, and convenience of storage. One device that produces a combination of these digital characteristics is a 3D printer, but its industrial use is limited due to low productivity and limitations with materials and physical characteristics. In particular, improvements are required to use 3D printers, such as better user accessibility owing to expertise and skills in modeling software and printers. Complementing this fact is the 3D pen, which is excellent in portability and ease of use, but has a limitation in that it cannot be digitized. Therefore, in order to secure a digitalization capability and ease of use, and to secure the safety of printing materials that pose controversial hazards during the printing process, research problems and alternatives have been derived by combining food, and digitization was demonstrated with a newly developed 3D pen. In order to digitize the 3D pen, a sensor in a structured device detects the motion of an analog 3D pen, and this motion is converted into 3D data (X-Y-Z coordinate values) through a spatial analysis algorithm. To prove this method, the similarity was confirmed by visualization using MeshLab version 1.3.4. It is expected that this food pen can be used in youth education and senior healthcare programs in the future.

Color laser printers are nowadays abused to print or forge official documents and bills. Identifying color laser printers will be a step for media forensics. This paper presents a new method to identify color laser printers with printed color images. Since different printer companies use their own printing process, each of printed papers from different printers has a little different invisible noise. After the wiener-filter is used to analyze the invisible noises from each printer, we extract some features from these noises by calculating a gray level co-occurrence matrix. Then, these features are applied to train and classify the support vector machine for identifying the color laser printer. In the experiment, we use total 2,597 images from 7 color laser printers. The results prove that the presented identification method performs well using the noise features of color printed images.

As makerspaces continue to be introduced in academic libraries in Korea, this study explores potential operating strategies of, and long-term justifications for, makerspaces as digital literacy eduational spaces and services at academic libraries. By examining related literature reviews and case studies of makerspaces, this study analyzes various programs and their respective creation, funding, development, and outcomes, including educational value and library-specific goals such as digital literacy and lifelong learning. This study also considers the perspectives of librarians at academic libraries in Korea who were asked about the purpose, impact, and limitations of makerspaces. Certain common themes appear: for example, it is necessary for makerspaces to resolve challenges related to stable funding, as well as staffing and training of professional librarians assisting with the on-the-ground operation of makerspaces. This study proposes that designing makerspaces for an academic library setting goes deeper than providing a collaborative environment with access to new technologies like 3D printers and laser cutters, and it may be uniquely appropriate to draw connections to libraries' objectives to provide digital literacy education and universities' mission to foster innovation and creativity among students.

As 5G is getting developed, people are getting interested in immersive content. Some predicts that immersive content may be implemented in real life such as holograms, which were only possible in movies. Holograms, which has been studied for a long time since Dennis Gabor published the basic theory in 1948, are constantly developing in a new direction with digital technology. It is developing from a traditional optical hologram, which is produced by recording the interference pattern of light to a computer generated hologram (CGH) and a digital hologram printer. In order to produce a hologram using a digital hologram printer, holographic element (Hogel) image must first be created using multi-view images. There are a method of directly photographing an actual image and a method of modeling an object using 3D graphic production tool and rendering the motion of a virtual camera to acquire a series of multi-view images. In this paper, we propose a new method of getting image, which is one of the visual effect, VFX, producing multi-view images using chroma key composition. We shoot on the green screen of actual object, suggest the overall workflow of composition with 3D computer graphic(CG) and explain the role of each step. We expected that it will be helpful in researching a new method of image acquisition in the future if all or part of the proposed workflow to be applied.

Stop-motion animation, which is based on the physical object and is shot frame by frame, is an traditional art of animation. As an independent art form, it has formed a unique art language through a century-long development. With the continuous exploration by animators, stop-motion animation has actively combined with digital technology, and has made a great progress in the use of materials and the technique of filming. the introduction of digital technology not only enriched it's artistic expression, but also laid the basis for it's sustainable development in the new era. This study investigates how 3D printer technology affects the production process and industry of stop motion animation.

This study on the proofing what used to correct the color difference between the photo image and offset press. Printing photos with color offset press always make the differs, because of the difference in gamut. Photographer hopes to be able to use the proofing with inkjet printer for reduce these differences. In this study, I experiment with various ways for the proofing by photographer directly. It is using the ink jet printer and image outputs of the various mode was applied to a variety of color setting value. And calculate the output image using a spectrophotometer and compared with the image of offset press. At last I can found a very similar color setting value with the offset image. After all this research is to obtain a result of finding out proofing work flow through method to measure and how to apply various color setting value results.

As the concept of open source extends beyond the scope of software, many companies are also introducing business models using open source concepts. This study is a study on how to create a web-based open-source platform using a 3D printer and aims to create an open-source platform modeled on the Kidults community where users are highly willing to participate. The research method established the direction of initial platform production by collecting basic data through the usability of the platform and Toy design preferences and propensity analysis through research on open source use cases by various companies and user surveys in the Kidults Community. Features unique platform Toy sources that are freely reinterpreted by the user and re-shared and sold to the platform. Research should continue to boost user motivation by activating communities within the platform.
