This paper aims to propose a framework of content creating group with creativity under new convergence environments. The framework is built based on content concept hierarchy(deep/surface) relating with the creativity of group members. The diversity of group members(potential creativity) decrease and change into creative abilities in one unified view at each content concept hierarchy in time. To do this, three methods of building a creative group(interaction-base, direction-base, hybrid) are proposed. Cooperating processes and operators are designed to promote creative abilities in the content producing group. These cooperations are considering new media convergence industry's job road map(IPTV) and fundamental content attributes(semantic, narrative, discourse). In the framework, creative content is produced with the help of member's cultural openness, media richness and synchronicity, hierachical adaptability on dissimilarity. Deep level creativity of cognitive semiotics on moving image content is composed of psychological, transformational, situational creating abilities in the structure of group members. Designing analogy, metaphor, symbol operators help members to traverse deep structure of content concept hierarchy. Our framework has strong points to relate fundamental content deep structure with structure of content producing group and to induce creativity on cognitive structure of human being.

To implement a cloud game service platform supporting multiple users and devices based on real-time streaming, there are many technical needs, including game screen and sound capturing, audio/video encoding in real time created by a high-performance server-generated game screen, and real-time streaming to client devices, such as low-cost PCs, smart devices, and set-top boxes. We therefore present a game service platform for the running and management of the game screen, as well as running the sound on the server, in which the captured and encoded game screen and sound separately provide client devices through real-time streaming. The proposed platform offers Web-based services that allow game play on smaller end devices without requiring the games to be installed locally.

We present a method for tracking and interaction based on hybrid sensing for virtual environments. The proposed method is applied to motion tracking of whole areas, including the user's occlusion space, for a high-precision interaction. For real-time motion tracking surrounding a user, we estimate each joint position in the human body using a combination of a depth sensor and a wand-type physical user interface, which is necessary to convert gyroscope and acceleration values into positional data. Additionally, we construct virtual contents and evaluate the validity of results related to hybrid sensing-based whole-body tracking of human motion methods used to compensate for the occluded areas.

We present a system for generating 3D personalized figures. This system provides 3D figures model modification and combination functions based on the content-awareness. The integrity of the 3D model must be guaranteed at the time of slicing of the 3D model for 3D printing. In addition to this, with 3D printing, we generally have to print a hollow model in order to save money, time, and the integrity of the print. This paper proposes the automatic algorithm that creates the 3D individual figures with depth sensor and the easy UI functions for deformation, thickness adjustment, and combination of the generated 3D figures model based on the content-awareness. Our proposed method maintains the unique features of the generated 3D figures and ensures the successful 3D printing.

The purpose of this study was to examine the impact of the application of a creative thinking technique for development on the creativity and attitude toward science of the students in elementary school. In order to better assist students' levels of creative thinking process, creative thinking techniques were reorganized based on the features of creative learning content in science textbooks. Furthermore, related units from an elementary science textbook were analyzed to map out the lesson plans. The findings of the study were as follows. First, the creative thinking technique developed in this study could be applicable to teaching-learning activities. When a creative thinking technique is applied, that should carefully be selected in consideration of all the creativity elements to be covered in class, and that should be used in a manner to be covered in class, and that should be used in a manner to be appropriate at learner level. Second, the utilization of the creative technique turned out to have a good impact on boosting the creativity of the elementary schoolers. Third, the utilization of the creative technique turned out to exert a good influence on fostering the school children's attitude toward science.

Unlike traditional retail formats, the metaverse offers diverse shopping experiences, ranging from content that mimics reality to content that transcends reality based on its characteristic of virtuality. This study elaborates on the concept of virtuality within store environments and investigates how the virtuality level of a metaverse store influences consumers' creative consumption by mediating the flow experience. Additionally, it examines the interaction effect of creative product-seeking tendencies and individual characteristics on the relationship between flow experience and creative consumption behavior. A web-based experiment was conducted on young Korean female adults who experienced metaverse shopping. Ninety-one samples were analyzed using exploratory factor and bootstrap analyses with SPSS Macro process Models 4 and 14. The findings demonstrate that store virtuality (low vs. high) increases consumers' purchase intentions of creative fashion items by enhancing their flow toward the shopping experience. Furthermore, the effect of flow experience on creative consumption is strengthened when consumers have low creative product-seeking tendencies. This study contributes to expanding the concept of virtuality in virtual retailing and provides insights for fashion retailers planning to create virtual shopping spaces within the metaverse platform.

So far, there have been studies to verify the effectiveness of creative advertising contents, but there have been few studies explaining why creative advertisement contents are effective in consumer cognitive processes. The purpose of this study is to examine the effect of creativity of ad contents on desire to postpone cognitive closure and ad attitude. Furthermore, the cause of the advertising effect of the creative advertisement contents was set as disfluency and the relationship between the related variables was verified. Research has shown that creative advertising does not directly produce positive advertising attitudes, but it also forms ad attitudes through mediating effects of disfluency. In addition, it was found that disfluency mediated the desire to postpone cognitive closure in creative advertising. In summary, this study finds that the disfluency of advertising is an important variable for enhancing the advertising effect of creative advertisement. This study verified the advertising effect of creative advertisement by connecting it with consumers' cognitive variables.

Although it is widely acknowledged that enhancing creativity is an important educational theme on which schools should depend and embody their educational goal and activities, how to do it can be characterized as 'piecemeal' without a whole picture of it. Thus, school practices of creativity education has been disoriented, discontinuous, short-term, and peripheral in nature. In this practical context, a theoretical model of creativity education was developed in ways in which several theoretical concepts based on research findings on a variety of aspects of creativity education were compiled and organized. The core of the model was creative problem solving process to which the goals and the mediating variables of creativity education were connected in relational fashion. By giving repetitive opportunities for creative problem solving geared to producing the results that are novel and useful for the individual as well as the socity, it was conceptualized that two educational goals could be achieved: a short-term goal of developing creative potential of the individual and the long-term goals of self-actualization of the individual and contribution to the society. It is also conceptualized that creative problem solving can be influenced in positive manner by several mediating variables: content knowledge and skills, creative cognition, creative motivation and attitudes, and creative environment. The creative environment is composed of psychological and physical conditions and provides a basis for creativity education. The former three variables are conceptualized as necessary conditions for the effectiveness and efficiency of creative problem solving, when provided appropriately. The four mediating variables ware conceptualized as mutually affecting so that the development of one variable influences positively that of the other, and vice versa. In terms of practical perspective of teaching creativity, developing creative potential, self-actualization, and contribution to society are the goals; creative problem solving process is the methodology; content knowledge and skills, creative cognition, and creative motivation and attitudes are the content; and creative environment is the condition of creativity education. The model is not yet perfect but needs further explorations to make it more detailed in clarifying various relationships. For instance, how the creative problem solving process can be differentiated in teaching various subject matters is yet to be explored. Thus, the model proposed in this study should be regarded as a general model of creativity education, and is relatively sound to be adopted in school practices since it is based on the theoretical as well as empirical study findings on creativity. However, the proposed model needs to be validated through empirical researches in real teaching settings.
