Based on a bond-based peridynamics theory for dynamic crack propagation problems, this paper presents a design sensitivity analysis and optimization method. Peridynamics has a peculiar advantage over the existing continuum theory in the mathematical modelling of problems where discontinuities arise. For the design optimization of the crack propagation problems, a non-shape design sensitivity is derived using the adjoint variable method. The obtained adjoint sensitivity of displacement and strain energy turns out to be very accurate and efficient compared to the finite different sensitivity. The obtained design sensitivities are futher utilized to optimally control the position of bifurcation point in the design optimization of crack propagation in a plate under tension. A numerical experiment demonstrates that the optimal distribution of material density could delay the position of bifurcation.

Open-ended problems can foster deeper understanding of mathematical ideas, generating creative thinking and communication in students. High-order thinking tasks such as open-ended problems involve more ambiguity and higher level of personal risks for students than they are normally exposed to in routine problems. To explore the classroom-based factors that could support or inhibit such higher-order processes, this paper also describes two cases of Singapore primary school teachers who have successfully or unsuccessfully implemented an open-ended problem in their mathematics lessons.

These days, public attention is being directed to the design processes by which a final outcome can be produced to achieve its goal according to the logical plans, as it is hard to address recent problems in design by the existing intuitive way due to the paradigm shift of design. Thus, this study aims to suggest creative fashion design processes to create a product as a final outcome by intentional and systematic processes. This study showed that design is considered as comprehensive problem solving processes, and it proposes framework of processes by integrating processes of industrial design and fashion design. In addition, this study classified creativity development methods that can be implemented to fashion design into promotion of ideas, breaking out of stereotypes, and extension of search areas. These creativity development methods can be applied to fashion design processes in order to make plans and strategies systematically and help you to choose the best ways to solve problems by processes.

In this paper, the creation method of edutainment content among cultural content types was studied. Edutainment aimed to enhance the creative thinking power through the "TRIZ theory" as an element of fun and education for learners at the same time. In this study, the modified OSTM-TRIZ theory was used not only in the technical field but also in the general sector. I proposed a model in which creative thinking can be enhanced to solve problems by analyzing contradictions encountered in the process of presenting problems. Nonlinear digital storytelling in animated folktales can elicit sufficient curiosity from learners, and problem presentation, problem resolution and contradiction analysis using OTSM-TRIZ work as an educational system to develop learners' creativity.

Although the acquisition of information may be done individually, knowledge is created from the social context of peers, teachers. And feedback on the appropriateness and effectiveness of their knowledge and skill is commonly received. Learning occures effectively within environment that have shared understanding of problems and various tools to solve problems. The purpose of this study is to apply the main principles of creative Problem solving and develop e-PBL(Problem-Based Learning) to enhance creative problem solving skill. In this research, the group of students who studied by means of e-PBL based on web 2.0 showed much more satisfaction and problem solving skill than the other group of students who did by e-Learning.

As interpretation of descriptive illustrations without caption differs from each viewer, it is deemed that the effect of attention is represented differently and the acceptance level of any advertisements will be ultimately different according to the visualization method of concept in the creative. The purpose of this research is to recognize the reality and status of visualization for real estate ads in newspapers via visualization analysis through Otto Kleppner's visualization model and to reasonably and efficiently conduct creative of real estate ads by representing problems and their solutions based on the surrey. These activities are to more efficiently produce real estate ads, which occupy a relatively important portion in newspaper ads.

Teaching and learning research is essential to prepare for the era of the 4th industrial revolution. We must strengthen the creative educational capabilities of prospective teachers by improving the curriculum and teaching-learning model of teacher training colleges. Future education should foster creative thinking based on communication and collaboration. In this study, we improved the future teaching and learning model and applied it to actual classes. In addition, we verified the effectiveness by conducting pre- and post-surveys on the capabilities of future creative teachers. The survey consists of common satisfaction questions and questions about future creative teacher capabilities. As a result of the analysis, we confirmed that the capacity of future creative teachers increased.

This planning afford promise of implement about the family life tasks and preventive interventions of family life problems or issues. The conceptual forcus are on the values, interdependence, wholeness, adaptation and balance of human life. This study provide of the basic about the social education program and family life education for quality of life.

This study analyzed the features and problems of one-person creative company development policy by using the image of brand identity of one-person creative company and the model of the symbol square. In order to solve the youth unemployment and to induce youth foundation, Korean government particularly Small and Medium Business Administration (SBA) paid great attention to 'One-Person Company' followed by One-Person Knowledge Company policy in 2008. Finally, this policy became One-Person Creative Company in 2009 when SBA faced criticism. However, according to semiotics analysis, symbolic conflicts were found in the policy given that this policy was not considered the role of the co-founder in venture ecosystem. This study provides practical implications for new directions of the one-person creative company policy of government; (1) one-person knowledge company ${\rightarrow}$ (2) one-person creative company ${\rightarrow}$ (3) 1+1 creative company.

Creative works such as webtoon and web novel are part of property rights. However, illegal copies of them are distributed on the internet easily, which raises social issues in today's society. In order to tackle these problems, this paper proposes and presents a blockchain based copyright management system that ensures forgery prevention, robust security features, improving trading performance, cost-effective, and enhanced visibility. The system allows a user to register creative works formally just the same as before registration and also to register simple creative ideas just anytime. In the latter case, if an idea or a thought flashes across through somebody's mind, he or she can register it to the system immediately without formal registration process and afterward, can utilize a way to prove its originality through the system. Regarding large size images and video files of creative works, the system reduces data size and storage volume sharply to be processed by network entities by storing original creative works separately and including only the hash result of creative works to the transactions.
