As areas of ICT devices expand due to development of fourth industry, Smart Jewelry is being released. Jewelry is not only a fashion tool to dress up the human body as it merges with the functional aspects of smart devices, but it also delivers the information needed to improve users' living conditions and the interaction of the information needed is likely to be expanded. Although wearable Jewelry is not widely popular with consumers due to its recognition that it is a Smartphone aid and technical limitations, it needs to be ultra-smallized and improved in design. By analyzing emotional types according to design, materials, and colors, focusing on the current wearable jewelry products, the company aims to contribute to enhancing the value of creative smart jewelry by thinking about how smart jewelry will stimulate people's emotions.

Disney animation can be said to be part of American culture and art. With the changes in American society and culture, we can see the changes in the personality and social status of female characters in Disney animation. Especially in the Disney animation works published after 2000, many works showing equality in the social abilities and status of women and men have been published. In this study, the characteristics of female characters of the 20th century and the 21st century is compared and analyzed the characters of Elsa and Anna, who expressed the female image in a metaphorical way of 'Frozen 2'. And studied the characteristics and meanings of clothing and colorful shapes. This paper reveals the design elements needed to construct a gender-equality image of female characters, and hopes that it will become a useful research material for the animation industry and academia in the future.

The visual, sensible and social situation that the modern digital technologies create became the background for the works of architects in extreme modernism and their space modeling suggested another possibility that was emancipated from the restriction of a property of matter and gravity in the existing space. The architecture design process using the digital technology has been attempted in diverse ways and summarized with several characteristics such as displacement, nonlinear space, flexibility of space and non-Euclidean geometry system. However, the conceptual and very technical design process that is called as digital architecture has been indiscriminately used with mixed meanings and the common features and differences between works and theories are not studied. This study aims to classify and identify the digital architecture by type as analyzing the non-linear composition process that is common in the digital architecture.

In this paper, a new watermarking algorithm for STL files which contains 3D geometric information as triangular facets is proposed. STL files are widely used in rapid prototyping industry as a standard interchange format. The proposed algorithm inserts multi-bit watermark information into the surface normal vector and vertex description area of STL file without distorting the original 3D geometric information. According to the watermark bits, the position of normal vector and the direction of vertex sequence are modulated. The proposed algorithm is robust to the attack of changing the order of the triangular meshes. In addition, the invisibility requirement is also satisfied. Experiment results show that the proposed algorithm can encode and decode watermark bits into the various STL files without any distortion of 3D shape.

Reincarnation, literally means "to be made flesh again". It is a mystical belief that the soul lives again in a new body after death. In this study, both material and spiritual elements are reincarnated in the form of the formative art in our life. This is similar to the notion of transmigration of the souls in Buddism and Taoism. Even a work of low merit can be an artifact when we give a new meaning and value through the reincarnation. Reincarnation opens another dimension in the formative art and it can be a new source of energy Andy Warhol, who is a central figure in the pop art movement, seems to have an idea of reincarnation in the base of his work. In Korea, there are many experimental arts in design and advertising which shows reincarnation. In the modem society, the activity and mind of reincarnation have been enhanced through Internet and digital medium and people consider reincarnation as a universal philosophy in the art. Especially, the reincarnation as a continuum of design has many implementations. Now the object will be freely adopted, and transformed and it will open a new age in the formative art. We should be ready to enjoy the arts.

In this study, we propose a method for moving a device such as a flexible air sculpture while stably maintaining the user's desired posture. To accomplish this, a robot system with a structure of a mobile robot capable of running according to a given trajectory was studied by applying the PI algorithm and horizontal maintenance posture control using IMU. The air sculptures used in this study often use thin strings in a fixed posture. Another method is to put a load on the center of gravity to maintain the posture, and it is a system with flexibility because it uses air pressure. It is expected that these structures can achieve various results by combining flexible structures and mobile robots through the convergence process of digital sensor technology. In this study, posture control was performed by fusion of the driving technology of AGV(Automatic Guided Vehicle),, a field of robot, and technologies applying various sensors. For verification, the given performance evaluation was performed through an accredited certification test, and its validity was verified through an experiment.

A fundamental problem in digital holography is the presence of zero-order noise in the reconstruction process, which decreases the signal to noise ratio(SNR). For many applications, that reduction of SNR makes digital holography impractical, so a great number of approaches have been tested in order to overcome such a problem. In this paper we use the scanning method to suppress the zero-order diffraction noise and the interference noise between object beams. We demonstrate that it is possible to increase the image quality with the scanning method.

We report here on the application of a digital holographic microscope as a metrology tool for the inspection and the micro-topography reconstruction of different micro-structures of phase shift photo-mask (PSM). The lithography by phase shift photo-mask uses the interference and the pattern of the PSM is not imaged by general optical microscope. The technique allows us to obtain digitally a high-fidelity surface topography description of the phase shift photo-mask with only one hologram image acquisition, allowing us to have relatively simple and compact set-ups able to give quantitative information of PSM.

Digital holography and refractive index difference are used to measure a high aspect ratio's patterns. When interference fringes are very closely spaced, the phase data containing high frequencies where $2{\pi}$ ambiguities cannot be resolved. In this technique, the optical path difference is decreased by decreasing the refractive index difference. As a result, we solve the $2{pi}$ ambiguities. Also, this technique is applicable to measure the refractive index if the shape of the sample is known.

Minimalism, which started with the subtle distinction between the end of modernism and beginning of post-modernism, was not limited to the fine arts but also spread through architecture, fashion, and the rest of the design industries. this historical study is considered a logical, user experience-based design process, the latest issue derived from the collision between minimalism and the digital environment is not limited to practical industrial design processes, but also their theoretical study. the results show that user experience-based design process and minimalism share many of the same qualities. based on these similarities, minimalism and user experience-based design process can be grouped together both academically and theoretically for establishing a future academic template for the digital designing process.
