본 논문에서는 비전공자 대상의 학습자 눈높이에서 흥미와 재미를 유발하고, 실제 비전공자의 컴퓨팅사고력(Computational Thinking)을 향상시키는데 콘텐츠에 따라 학생의 관심도가 달라질 수 있다는 분석결과를 보여준다. 기존의 SW교육 시스템(EPL: Education Programming Language)의 단점인 실행 중심의 SW교육 시스템에서 벗어나 실제 생활에서의 기초적인 컴퓨팅 사고 관련 예제로서 모델별 단계적 접근을 시도하면서, 실제 생활 속 컴퓨팅 사고력 기반의 문제해결력을 높일 수 있도록 피드백 방식이 비전공자 SW교육에 끼치는 영향력을 확인하였다.

Purpose: This study proposes a method for developing a model that predicts the probability of traffic accidents in advance to prevent the most frequent traffic accidents in the military. Method: For this purpose, CRISP-DM (Cross Industry Standard Process for Data Mining) was applied in this study. The CRISP-DM process consists of 6 stages, and each stage is not unidirectional like the Waterfall Model, but improves the level of completeness through feedback between stages. Results: As a result of modeling the same data set as the previously constructed accident investigation data for the entire group, when the classification criterion was 0.5, Significant results were derived from the accuracy, specificity, sensitivity, and AUC of the model for predicting traffic accidents. Conclusion: In the process of designing the prediction model, it was confirmed that it was difficult to obtain a meaningful prediction value due to the lack of data. The methodology for designing a predictive model using the data set was proposed by reorganizing and expanding a data set capable of rational inference to solve the data shortage.

In this paper, we want to know the effect of elementary students' creativity thru the play-centered computer science educational program. We extracted educational content from computer science. The students addressed to the problems thru the play and found their own solution. Research result show significant difference in creative attitude of sub-area of creativity. We found that students were actively involved with pleasure in play, the rules of play was actively keep.

Recently, the importance of Research and Development(R&D) security as well as R&D investment is emphasized in the flow of technology hegemony competition, where technology is directly related to national competitiveness.However, despite the enormous impact of the R&D security failure results, research output leakage accidents continue to occur.To solve this problem, this study analyzed leakage accidents and cases of R&D output and concluded that it is priory to develop regulations to raise security awareness at the field researcher level rather than the macroscopic security management system. In addition, in order to design the direction of the researcher security measures, observational study was conducted at the university research site, and four directions were presented, including case analysis and integration. The direction for designing researcher security measures will be used as a basis for developing security regulations specialized in future research sites and security management systems for research institutes.

교통문제는 과거에 비하여 보다 복잡해지고 다양해지고 있으며, 이러한 교통문제를 해결하기 위한 방안을 도출하는 분석기법 또한 다양해지고 있다. 이러한 기법중 안전도 평가기법에 관한 연구는 선진국에서는 1970년대부터 진행되어 왔으나, 이에 반하여 국내에서는 최근에서야 안전도에 대한 문제가 부각되면서 이에 대한 연구가 시작되고 있는 실정이다. 본 논문은 국내 외 연구사례를 중심으로 교통상충기법(TCT)을 소개하였고, 가장 진보된 방법인 스웨덴의 상충분석기법을 기반으로 국내에 적용할 수 있도록 모형을 개발하고 심각한 정도에 따라 4개 죤으로 분류하여 위험순위를 평가할 수 있는 방법을 제시하였으며, 실제로 이러한 상충분석기법을 국내의 3개 교차로 분석에 적용하여 보았다. 사고와 상충간의 conversion factor는 수집된 자료의 부족으로 사고자료의 심각도까지는 고려하지 못하였으 나, TA값을 구하고 4개죤 분류를 통하여 위험순위를 분석하여 교차로의 안전도평가에 이용할 수 있음은 보여주었다. 상충조사 분석은 안전도 평가를 저 비용과 짧은 시간내에 보다 상세한 결과를 도출할 수 있다는 점과 대상지의 사전 후 단기간 평가 방법에 가장 효과적인 기법이라는 측면에서 국내 안전도 평가에 많이 적용되기를 바란다.

21세기 정보화 시대에는 알고 있는 지식의 대부분이 짧은 생성 주기를 가지게 되어, 다양한 변화의 시대가 될 것으로 예상하며 우리는 이것을 체험하고 있다. 열린수업에 대한 연구가 끝나기도 전에 수준별수업, 이번에는 멀티미디어 수업, 올해는 수행평가와 체험수업 등으로 다양한 변화를 권장받고 있다. 그리고 변화는 더욱 가속될 것이며, 또 다른 새로운 이름의 학습모형이 계속해서 나올 것이지만 그래도 일관된 방향성을 찾는다면, 가르친다는 것이 '지식의 전달'에 근거한 권위적인 모델로부터 '배움의 자극'을 제공하는 학생중심의 수업으로, 개별적인 학습활동과 더불어 소집단 공동학습활동을 중시하여, 발표${\cdot}$토의 활동과 관찰, 조사 등의 자기주도적인 학습능력과 협력 학습능력을 배양하는 쪽으로 바뀌어 가는 것이다. 다음의 예는 구서여자중학교 중심 MathPower 교과연구회에서 수행하고 있는 수학적 힘을 기르는 몇 가지 방법으로, 수학적 개념을 가르치는데 가장 적절한 예는 아닐 수도 있지만, ${\cdot}$ 학습수준을 고려한 교양으로서의 수학. ${\cdot}$ 협동적으로 사고하고 문제를 해결하는 의사소통 수단으로서의 수학. ${\cdot}$ 창의성과 인재에 중점을 둔 수학. 교육으로, 다양한 학습자료의 제작 및 활용으로 교실이 다른 사람과 협동적으로 사고하며, 수학적인 아이디어를 나누는 장소가 되어, 가슴이 따뜻하며, 재기발랄한 아이들이 IQ와 EQ, 그리고 창의력을 두루 맛볼 수 있었으면 하는 바램으로 정리한 것입니다.

The aim of this paper is to explore and understand the gifted student's characteristics such as NetLogo programming patterns, attitudes, his/her interest in problems solving. Based on transcripts and coding video frames, we explored the meaningful scenes to come up with thinking patterns, NetLogo programming patterns, attitudes, behaviors on tasks such as drawing regular starlike shapes. This case study contrasts with two other students revealing their unique characteristics both in computational thinking patterns and coding activities. The participant reveals his own ways of finding a clue and elaborating it further for coming up with concise NetLogo coding. This paper provides cross-case discussion and future research direction on how to improve gifted education in terms of problem solving in creative ways.

In the creative problem solving processes, the core was to generate unique and various ideas. Thus, an assumption reversal thinking skill needed to be considered as a concrete method that could help students who have difficulties with generating ideas. In this study, we applied the assumption reversal thinking skill to university students and explored the characteristics of the idea generation process. On the basis of the results, we found that the assumption reversal thinking skill helped students generate new ideas, inducing their perspective changes. Therefore, we could ascertain the possibilities of the assumption reversal thinking skill as a thinking frame supporting students' idea generation. However, there is a need to develop methods for students to exclude prejudice by theoretical judgment, intervention of the value, and experience for fostering more effective assumption reversal thinking. Also, ways should be considered so that students would be able to cultivate task commitment and courage of implementing new ideas, bearing criticism from others.

Growing in its size, the contents of the teaching-learning programs for mathematically gifted children from A program in Seoul Metropolitan Office of Education were examined in terms of the individual subjects provided through the courses of gifted education programs, and it was evaluated based on the revised version of the existing module. As a result, the educational objectives of teaching-learning program were clear, differentiated and obtainable. Among the program, the advanced parts were more than the selective parts, which mainly consisted of numbers and calculation, shapes, regularity and problem solving parts and had latest contents of research in balance. Additionally, every part of the program needs mathematical and creative thinking and approach and has proper evaluation index for problem solving. The presented materials in the programs are specific and appropriate, though some of them did not suggest the evaluation index for cultivating personality and value clearly and the reference books. The teaching-learning programs were focusing on problem-based learning and cooperative learning and using performance assessment for evaluation.

A design thinking-based collaborative workshop in which various stakeholders in the milk processing industry circulation ecosystem participated shows a new problem innovation paradigm that encourages the spread of practical prototyping culture. in the expression of empathy and collective intelligence among members on facing issues, the conversion of collaboration and communication methods, the business handling of the organization based on the design work method as 'creativity mechanism'. In this workshop, which was promoted in three stages of 'approach to problems', 're-definition of problems', and 'experience-based future vision design', participants themselves redefine real problems in terms of the accuracy of feed orders between feed suppliers and livestock farmers, ordering of feeds on time, cost reduction of feed supply and present new alternatives and expanded business areas. The results suggested in this workshop suggest the usefulness of design thinking in business innovation in that they presented how to approach the problem and a creative thinking system to find its solution to direct and indirect stakeholders of the industry as well as the improvement of supply and demand rate of livestock feed and quality.
