This study aims at examining text contents and its writing directions and analyzing their validity to develop text books of "invention and problem solving", which will be used for advanced courses of specialized high school of invention and patents. To develop text book contents and writing direction, literature research and professional association meetings were performed and to verify validity on developed text book contents and writing direction, survey research was performed. The subjects of survey research to verify validity consist of seventy five teachers who participated in the training course for invention leaders hosted by International Intellectual Property Training Institute (IIPTI) of Korean Intellectual Property Office (KIPO). To examine validity on text writing directions, each area of the text, themes, and modules, questionnaires that consist of multiple choice questions, and open questions that participants can describe their opinions were developed. Text book writing plans are included in the questionnaires to help the understanding on text book contents. The conclusions drawn from results of validity analysis are as follows: First, each theme and modules of 'invention and problem solving' were properly developed for common text books for the advance course of specialized high school of invention and patents. Second, as for the text book writing direction of 'invention and problem solving', text books emphasize research ability and creative thinking. They were developed to help increase critical thinking, logical thinking and problem solving ability.

The purpose of this study was to verify that students' interest in team activities for problem solving, the effect of interest on it, and students' changes in perceptions and their behavioral characteristics in the process of problem solving. The study reviewed documents prepared by students, such as work sheets, descriptive questionnaires, works and their photos, student activity photos and observation journals of teachers. The results of this research are as below. First, a problem solving team activity for making a model car was considered an interesting assignment by more than 90% of male/female students. The fact that female students could be more focused on this assignment than male students was discovered. Interest in the assignment not only had an influence on the points from the start (the blueprint) to the end (model cars completed based upon the designs) of problem solving, but also provided the traction power behind the assignment. Second, the problem solving team activity allowed the students to change their existing recognition (thoughts) while positively taking a lead or indirectly utilizing various learning experiences (including experiences of failure). Third, $2^{nd}$ graders in middle school had a tendency to solve problems in dependently rather than to receive help from others when they encountered problematic situations.

The Center for Science Gifted Education (CSGE) of Chongju National University of Education was established in 1998 with the financial support of the Korea. Science & Engineering Foundation (KOSEF). In fact, we had prepared mathematics and science gifted education program beginning in 1997. It was possible due to the commitment of faculty members with an interest in gifted education. Now we have 5 classes in Mathematics, two of which are fundamental, one of which is a strengthened second-grade class gifted elementary school students, and one a fundamental class, and one a strengthened class for gifted middle school students in Chungbuk province. Each class consists of 16 students selected by a rigorous examination and filtering process. Also we have a mentoring system for particularly gifted students in mathematics. We have a number of programs for Super-Saturday, Summer School, Winter School, and Mathematics and Science Gifted Camp. Each program is suitable for 90 or 180 minutes of class time. The types of tasks developed can be divided into experimental, group discussion, open-ended problem solving, and exposition and problem solving tasks. Levels of the tasks developed for talented elementary students in mathematics can be further divided into grade 5 and under, grade 6, and grade 7 and over. Types of the tasks developed can be divided into experimental, group discussion, open-ended problem solving, and exposition and problem solving task. Also levels of the tasks developed for talented elementary students in mathematics can be divided into the level of lower than grade 5, level of grade 6, and level of more than grade 7. Three tasks developed and practiced are reported in this article.

Nudge, which is recently in the spotlight again, refers to inducing a person's behavior change naturally rather than forcibly in behavioral economics. It is used not only in behavioral economics, but also in various fields such as design and communication, and is continuously expanding. Furthermore, it is used for entrepreneurship education as well as solving social problems in the public sector that are easily encountered in the surroundings. Given this aspect, it would be very meaningful to understand and analyze Nudge from the perspective of problem solving. Therefore, this study analyzed the usefulness and utility of Nudge from the perspective of problem solving. The usefulness of Nudge was confirmed through TRIZ technique, which is a representative technique for problem solving, and conversely, the utility of Nudge in TRIZ technique was also analyzed. The results of this study are expected to provide useful theoretical and practical implications for researchers and managers interested in knowledge management for problem solving.

The social problem-solving R&D is different from the goal and process in comparison with research aimed at scientific excellence and industrial innovation. It pursues social values and active participation of the end-user civil society. In this study, we try to derive its characteristics by analyzing the cases that are evaluated as successful social problem solving R&D project. In order to analyse the social problem-solving R & D case, these four variables are selected; 1) social and technological planning for problem solving 2) participatory technological development 3) law, system and delivery system development for innovation deployment 4) scale-up of new R&D process. Those are important issues identified through case studies: 1) the tools and support services needed to carry out social and technical planning effectively, 2) the role of the Living Lab to coordinate opinions with experts and users, 3) the legislative and institutional improvement activities as important as technological development, 4) researcher's change through interaction with end user.

Although more than 15 years have passed since the introductory design courses were opened due to the introduction of engineering education certification in the civil engineering field, these courses have been operated somewhat unsatisfactorily compared to their importance as an introductory course for engineering design. This is partially because the quality of classes is affected by the instructor's individual ability due to the fact that a standard training plan for these courses has not been established so far. Therefore, in this paper, we try to present a reference model for the introductory design course by introducing a class operation case established through continuous improvement process over the last 10 years at Chungbuk National University. This case aims to cultivate students' problem solving and system design skills by carrying out projects to develop egg drop and wood bridge systems based on creative problem solving methodologies. As a result of a questionnaire survey conducted after the class, we found that students' problem solving and system design capabilities were improved significantly and there was a meaningful increase in level of interest and attention in civil engineering by taking this class.

The purpose of this study is to extract empathy factor in scientists' problem-solving process and to examine how the empathy factor influences scientists' problem-solving situation. In this study, we selected six common persons among the scientists mentioned by creativity researchers. And through their autobiographies and biographies, we extracted elements of empathy from their case of problem-solving and categorized them. We analyzed cases from 12 books and 50 papers using Davis' empathy scale as an analysis framework and extracted common factors. As a result, the scientific empathy elements were extracted from a total of 182 cases, and 33 common elements were found. The validity of this case was verified through the content validity test of the science education specialist group. As a result, the I-CVI average was .86 and the S-CVI average was .90. For the empathy elements that scientists used in problem-solving cases, in cognitive empathy, three elements (empathy through other disciplines, empathy from the perspective of the research object, accommodating others' opinions) were extracted in terms of perspective-taking, and three elements (imagination thought experiment based on observation, thought experiment, feeling like part of object) in fantasy. And in affective empathy, three elements (influenced by fellow researchers' motivation, touching from the subject, excitement studying more) were extracted in terms of empathic concern and two elements (heartache for others' failure in their research, sensitivity to problems) in personal depression. This could not be said to be a perfect match for Davis' empathy, but it would be possible to define the scientific empathy elements based on these common elements found in the scientists' cases.
