This is a following study of the preceding study, Flexibility of mind and divergent thinking in problem solving process that was performed by Choi & Do in 2005. In this paper, we discuss the relationship between ability to shift a viewpoint and insight into invariance, another major consideration in mathematical creativity, in the process of mathematical problem solving.

Most of the Korean performing arts markets are not only small but also show their limitations in terms of their role as a platform for the promotion of performing arts and future growth prospects. This study started from the perception that the domestic performing arts markets need the cooperation between the markets in order to overcome the current situation and become the representative performing arts markets of Asia. To do this, we conducted surveys and in-depth interviews on market collaborations with domestic performing arts officials such as PAMS, Jeju Haevichi Art Festival and G-FAFE. For successful inter-market collaboration, the first is to change ideas and thinking about collaborations, second, to select programs suitable for direct supervision and collaboration based on evaluation of comparative advantage, and third, to establish and operate the 'Performing Arts Market Collaboration Promotion Committee(tentative name)'. And the fourth, starting from the sharing of the network that is most required at this stage, it is necessary to develop the sharing of manpower and places through mutual financial support or sharing between the central government, the metropolitan municipalities.

In the external inspection and packaging stages of products used in the semiconductor manufacturing process, there is a problem in which particles are adsorbed to the product itself or a carrying tool due to electrostatic discharge. This study presents a methodology that can improve the problem of adsorption of particles to a product by using a practical TRIZ technique. By applying the proposed practical TRIZ-based methodology, the problem was defined, and contradictions caused by product waiting time were derived. Among the derived contradictions, physical contradictions were set and the concept of 'space separation' was applied to derive solutions such as 'installation of Ionizer' and 'improvement of the layout of the workroom'. As a result of the experiment by applying 'Ionizer Installation' and 'Workroom Layout Improvement' derived through the application of practical TRIZ, it was confirmed that the particle adsorption problem that occurs during the waiting time of the product can be solved.Through this study, it is expected that workers, facility engineers, and technical engineers working at manufacturing processes will be able to effectively solve the problems they face through creative thinking and change of ideas by using practical TRIZ techniques, and contribute to innovative technology development and productivity improvement.
