Development of Artificial Intelligence Tutor System to Enhance Children’s Ballet Experiences

Abstract
This study proposes a non-face-to-face ballet experience system for toddlers according to the changing educational environment. The system proposed in this study is to encourage toddlers to naturally take in ballet through avatars by recognizing their poses based on machine learning, which in turn providing similar ballet movements demonstrated by artificial intelligence tutors. In order to plan this, the purpose of the study was to look at non-faceto-face cases of early childhood dance education and to suggest directions and detailed procedures for developing an artificial intelligence tutoring system for youngsters. As a result, related research data emphasized the datafication of dance movements, hyper-connected, superintelligence, surreal ballet practical education blended with ICT technology, and the importance of rhythmic robot and infant interaction. Existing cases of non-face-toface ballet education were studied, which were found to include augmented reality-based creative ballet education and AI-based classic ballet education. Based on the results of related studies and case studies, the running process of this system consisted of first, avatar generation, second, interaction with artificial intelligence tutor, third, pose recognition of kids, fourth, ballet movement demonstration and dancing, and fifth, video watching. In addition, a guide for implementing the service was presented. Through the system proposed in this study, it will be possible to provide practical guidance on the development of dance experience and educational system related to this in the educational industry in the future, and further contribute to the sound growth of toddlers and expansion of ballet art.

3D printing textile design and skirt manufacturing process using FDM 3D printing technology

Abstract
3D printing is a key technology leading the 4th industrial revolution, and it is possible to reduce manufacturing costs by using an additive manufacturing method that does not require molds and is used in various fields such as bio, medical care, and food. In the apparel industry, various studies are being conducted for textile production using 3D printing. This study intends to propose a skirt manufacturing process using a 3D printed textile. In the manufacturing process of 3D printing textiles and prototypes, first, a modeling design in the form of chain mail was developed using the Rhino 7.0 program. Second, the modeling design developed in this study was printed on a Fused Deposition Modeling (FDM) printer using various resins such as Acrylonitrile Butadiene Styrene (ABS), High Impact Polystyrene (HIPS), and Polyactic Acid (PLA), and the model was selected based on the stability and optimal design. The optimal modeling design was printed with High Impact Polystyrene (HIPS) resin, and the size was 25 × 25 × 8.7(mm)(L × W × H). Third, the skirt prototype was manufactured using an optimal modeling design, and the size of the skirt was adjusted to 0.3 times the actual size. The front and back parts of the skirts were connected using metal rings(inner diameter: 8mm, outer diameter: 10mm. Through this study, it was confirmed that 3D printed textiles can be applied as clothing materials and manufacturing clothing prototypes using them.

A Study on the Factors Influencing Consumers’ Switching Intention in Online Music Service

Abstract

As competition for online music services intensifies, consumers have a wider choice, increasing the possibility of service switching, while companies need strategies to prevent it. This study was conducted with the aim of providing strategic implications to companies by investigating what factors affect consumer switching intention for online music services and demonstrating it. First, by applying the PPM model developed in the migration theory, this paper tried to find out the factors that consumers switch from existing services to others. Through previous studies, sub-factors such as relationship quality and perceived value as push factors, alternative attractiveness and peer influence as pull factors, and switching cost and habit as mooring factors were derived. To find out the effect of these factors on switching intention, a survey was conducted on 66 consumers of online music services, and the collected data were used for analysis using SPSS ver 25.0. As a result of the analysis, the factors affecting the switching intention were relationship quality and alternative attractiveness, and it was found that each had a negative and positive effect. On the other hand, it was found that perceived value, peer influence, switching cost, and habit did not significantly affect switching intention. Based on these results, this paper provided practical implications to companies that operate online music services.

Abstract
This study aimed to identify user experience elements by determining the characteristics of asset management and consumption behaviors among career-beginners in the MZ generation. A literature review found that the MZ generation has conflicting characteristics regarding present value satisfaction and value asset management and investment. Based on the findings, in-depth interviews were conducted to understand specific behaviors in terms of asset management and  consumption, and the interview responses were then analyzed using affinity diagram to adduce the design considerations of “simple interaction,” “inducing even consumption behavior,” “satisfying the sense of reward through consumption,” and “practical feedback,” based on which a financial service was designed. Finally, a usability test was conducted, showing that it is necessary to provide asset management experience through an intuitive and simple process and to afford experience in consuming according to the user’s goal.

Abstract
The purpose of this paper is to find the elements necessary to increase user immersion in nonlinear narrative games. By analyzing cases for existing nonlinear narrative games, it was found that selection and story flow charts are necessary factors for user immersion. To verify these factors, we produced a nonlinear narrative game and a user test in the form of a working prototype was conducted to analyze the change in user immersion. Through this test, we confirmed that selection is an important factor in the user’s immersion and that the story flow chart is an incidental factor. Through this paper, I would like to explain that selection and story flow charts are factors that help improve user immersion in nonlinear narrative games.

A study on the convergence characteristics of the chorus of ‘淸, Open the Blue Sea’
– Focusing on Deleuze’s artistic thinkingPromoting Creativity in University Students: Development of a Design Toolkit Based on Design Thinking

Abstract
This study attempted to examine the direction of Korean contemporary dance by analyzing the method of using the chorus shown in ‘淸, Open the Blue Sea’ based on Deleuze’s art theory of art. Focusing on the dismantling and combination of various stage elements, which are an indispensable trend in contemporary dance, I tried to find out how Deleuze’s potential view of challenge and change from the measure of life is expressed in Korean contemporary dance. In particular, in ‘淸, Open the Blue Sea’ an important characteristic of ancient Greek tragedies, the possibility of dispersing the perspective of Korean contemporary dance, which constantly reflects on the boundary between tradition and modernity, was suggested.

User Experience Design for Motivation and Persistence of Repetitive Action:
AI Chatbot-Based Writing Application Service Proposal

Abstract
Modern people pursue a high-quality mental life and perform repetitive actions for inner stability. Writing is a process of subjectification, which is meaningful in itself to continue. Although practice is emphasized in order to get help from writing as a process of subjectification, it is difficult for many modern people to form the habit of writing. This study examined a design strategy that motivates users who find it difficult to practice to continue their behavior as a way to induce behavior habituation. To this end, I conducted user research to help the continuous practice of writing and derived a user-experience (UX) concept for a writing app that applies conversational interaction with an AI chatbot. Subsequently, the presentation of user’s writings and continuous conversation induction through notifications from chatbots was confirmed as a motivating factor that allows users to engage in repetitive actions without needing to make an effort of will. It is expected that various daily experiences will be urged through the chatbot interface, which can be utilized in various services where repetitive actions and continuous performance are important.

Current Status and Recognition of Artist Welfare Act of College Dance Majors

Abstract
Contemporary society’s culture and arts significantly contribute to the quality of life and happiness of individuals, and plays an important role in a nation’s power. However, unlike the culture and arts that change with the rapidly changing society, the rights of the artists and the welfare system for them have not been provided with realistic aids. The Artist Welfare Act was enacted in 2011 for the basic status and rights of artists, which had been neglected, and the Korea Artist Welfare Foundation was also established. Thereafter, measures have been taken for the artists’ welfare such as promotion of numerous businesses and various systems through the revision of the Employment Insurance Act. However, the dance field, where the focus is creative activities, still suffers from difficulties such as the limitation of measuring working hours and difficulties in securing social insurance. These facts describe the negative reality of the dance field and the vulnerability for the lack of social protections. Therefore, unless there are practical policy improvements that reflect the current situation, it will be difficult to reap the benefits of the artist welfare system in the future. In this study, a survey was conducted on the status and awareness of the Artist Welfare Act for dance majors, and the results of the study are as follows. First, regarding the “Awareness of the Artist Welfare Act of Dance Majors” question, “I have heard of it, but I do not know the contents.” showed the highest response. Second, regarding “the path I found out about the artist welfare project,” “I don’t know at all” was the foremost response. For “the project that I participated in or would like to participate in,” “supporting fund for artistic creation,”
“artist pass,” and “proof of artistic activity” got the highest response. Third, for “the most necessary welfare for dance artists,” “supporting fund for artistic creation” was the leading answer. These findings indicate that college dance majors are in a state of insufficiency in overall awareness related to the Artist Welfare Act. In addition, the results showed the greatest interest in economic welfare through dance performance projects, such as “supporting fund for artistic creation” and related support systems. It can be understood that the practical difficulties of artistic activities and economic difficulties experienced by college dance majors are closely related. Thus, this study provides useful data for artistic choreographic activities of university dance majors, suggesting means to promote them and improving their living stability. These findings can be expected to contribute to the development of the national culture and arts industry as a foundation for setting the direction of the “creative fusion of dance and artistic activities.”
