This article focused on contemporary American animation since the 1990s and later detailed clues to the theory that contemporary pop art style influenced contemporary American animation art creation expression and contemporary American animation. Knowing why American animation swept the world summarizes the art creation characteristics of modern American animation. After a combination of theoretical and actual animation works, the main manifestations of the postmodern pop art style in contemporary American animation: exaggerated and superficial shapes highlight character characteristics; rebellious colors reconstruct emotional perception; creation impacts the mass media-dependence; bizarre collage and repetition, embodying the postmodern pop spirit of jokes and spoofs, Etc. Through this, it is expected that the current analysis of American animation will provide new innovative ideas for domestic animation design and increase the competitiveness of domestic animation in international video animation.

'Burnout', which has been frequently used recently, is one of the representative expressions representing the psychology of modern people living in fierce competition. In this paper, I approached and analyzed two films, 'Hector and the Search for Happiness' and 'To Each His Own' from the perspective of burnout, which are considered two of the most healing movies for office workers. The symptoms of burnout in the work were lethargy, irritability, anger, insomnia, depression, and suicidal thoughts. In the case of 'Hector and the Search for Happiness' the clash of values from repeated consulting work, and in the case of 'To Each His Own', work overload, performance pressure, and the absence of a community of colleagues were the causes. This burnout state is visually expressed through the dialogues and expressions of the characters, as well as looking down shots of various sizes, low lighting, and placing objects in front of the main character. This intuitively expressed the symptoms of burnout, which is difficult to diagnose. In particular, it was confirmed through the movie that one of the diagnostic criteria for burnout, such as hobbies, physical activity, and the presence or absence of a fellow community, helps to get out of burnout.

From the perspective of a post-industrial society, the main purpose of this study is to clarify the theoretical principles that distinguish service design from product service system (PSS) and to propose a new integrated design strategy. Service design is a user-centered design technique for improving or innovating existing services and solving problems in a continuous exploration and iteration process. On the other hand, PSS is a cutting-edge business approach for organizations looking to boost their competitiveness by providing integrated product and service capabilities to clients while also enhancing system operations. This paper discusses the concepts of service design and PSS, the present state of research, and design methodologies using a literature search. The distinctions between service design and PSS are examined and summarized during the design process. The ultimate content proposed in this study is to incorporate user experience into the PSS design process and propose a systematic process to meet users' needs to effectively implement the service design concept.

In this paper, the concept and characteristics of the nuclear propulsion system were introduced and the state of the art for the nuclear-powered space propulsion in abroad were summarized. Since uranium used in nuclear propulsion has a very high energy density per unit mass, it has exceptional specific impulse performance compared to the existing chemical propulsion method and can reduce the amount of fuel loaded, thereby having advantage for long-distance exploration. For this reason, advanced countries in space development are recently spurring to the research of nuclear propulsion technology, and it is judged that the development of a propulsion engine using nuclear power is absolutely necessary in order to gain an competitive edge on the space development.

Recently as various contents are mass produced based on high accessibility, the media contents market is more active. Users want to find content that suits their taste, and each platform is competing for personalized recommendations for content. For an efficient recommendation system, high-quality metadata is required. Existing platforms take a method in which the user directly inputs the metadata of an image. This will waste time and money processing large amounts of data. In this paper, for media hyperpersonalization recommendation, keyframes are extracted based on the YCrCb color model of the video based on movie trailers, movie genres are distinguished through supervised learning of artificial intelligence and In the future, we would like to propose a utilization plan for generating metadata.

It is not easy to achieve the essential goal of knowledge management, which is to strengthen individual competence and organizational competitiveness, only by collecting distributed knowledge in the centralized knowledge repository conducted so far. In order to establish a sustainable knowledge ecosystem, we must expand knowledge production through exchange and cooperation, not independent knowledge production. Through this, producing meaningful and high-value knowledge resources becomes possible. Therefore, this study aims to design an integrated service platform that stores science and technology knowledge resources and reproduces and evolves knowledge through opening, sharing, and utilization. In order to evaluate its excellence, Five experts evaluated the designed platform on detailed items classified into planning adequacy, platform effectiveness, platform efficiency, and roadmap adequacy.
