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.

In this paper we describe Task-Based Problem Solving Adapters (TPSAs) for modeling a humam solution (through activity-centered analysis) to a software solution (in form of computer-based artifact). TPSAs are derived from the problem solving pattern or consistent problem solving structures/strategies employed by practitioners while designing solutions to complex problems. The adapters developed by us lead toward human-centeredness in their design and underpinning that help us to address the pragmatic task constraints through a range of technologies like neural networks, fuzzy logic, and genetic algorithms. We also outline an example of applying the TPSAs to develop a working system for assisting sales engineers of an electrical manufacturing firm in preparing indent and monitoring the status of orders in the company.

This study examined the effects of a robotics curriculum based on "Bee-Bot" on the scientific problem-solving ability on 5-year-old children. A robotics curriculum was also designed to enhance their scientific problem-solving ability. This study examined a 4-week robotics curriculum was conducted 12 times for 4 weeks. For this study, 14 children in kindergarten A in Korea were set up as a treatment group and 18 children in kindergarten B in Korea as a control group. It was found that children in the treatment group who engaged in the robotics curriculum using "Bee-Bot" performed better on scientific problem-solving tests. This finding indicates that an enhanced planning experience using "Bee-Bot" was beneficial for improving young children's scientific problem-solving ability. The implications for designing appropriate curricula using "Bee-Bot" robots for kindergarteners are addressed.

복합.융합화 능력을 겸비한 인재를 양성해야 하는 시대적 요구에 부응하여 공학자의 창의적 문제해결 능력 함양은 공학교육의 중요한 새로운 교육목표이다. 이 연구는 공학교육에 있어 실험계획 및 분석을 고려한 교육과정이 창의적 문제해결 능력을 뒷받침 할 수 있는 중요한 요소임을 지적하고 이것을 효과적으로 도입할 수 있는 교육과정의 설계에 그 목적을 두고 있다. 이를 위하여, 먼저 실험계획 및 분석의 교육주제에서 기대되는 학습 성과와 공학자의 기본적인 공학능력과의 연관성을 알아보았다. 그리고 전통적으로 산업에서 큰 비중을 차지하고 있는 기계공학계열학과의 현재 공학 교육과정에서 운영중인 실험계획 및 분석의 교육내용에 대한 현황을 조사하였고, 또한 해당 공학 전문가들의 주요 활동분야들 중의 하나인 연구논문의 작성에서 나타난 실험계획 및 분석에 관련된 지식의 활용 실태를 분석하였다. 마지막으로, 이러한 실증적 사례를 근거로 공학자의 기본 자질인 창의적 문제해결 능력 향상을 위한 하나의 수단으로서 효과적인 실험계획 및 분석의 교과를 도입한 공학교육 과정의 모듈을 개발하였다.

TRIZ is one of the most famous tools for creative problem solving. However, it is said that TRIZ is complicated and difficult to understand and apply to solve problems. In order to resolve these difficulties, this paper presents S-ARIZ, a simplified ARIZ(the algorithm for inventive problem solving). S-ARIZ revised ARIZ-85C on two ways. First, cause and effect analysis is used to define core technical contradictions and control parameters for the physical contradictions. Second, we add 5 inventive principles which revised SIT(systematic inventive thinking) partially to IFR-1 definition (Step 3-2 of ARIZ-85C) to solve the intensified technical contradictions systematically and effectively. It is expect that S-ARIZ can contribute to the rapid spread of TRIZ.

This paper addresses to the flowshop scheduling problem with blocking constraints. The objective is to minimize the makespan criterion. We propose a hybrid combinatorial particle swarm optimization algorithm (HCPSO) as a resolution technique for solving this problem. At the initialization, different priority rules are exploited. Experimental study and statistical analysis were performed to select the most adapted one for this problem. Then, the swarm behavior is tested for solving a combinatorial optimization problem such as a sequencing problem under constraints. Finally, an iterated local search algorithm based on probabilistic perturbation is sequentially introduced to the particle swarm optimization algorithm for improving the quality of solution. The computational results show that our approach is able to improve several best known solutions of the literature. In fact, 76 solutions among 120 were improved. Moreover, HCPSO outperforms the compared methods in terms of quality of solutions in short time requirements. Also, the performance of the proposed approach is evaluated according to a real-world industrial problem.

The purpose of the study was to develop the Arduino based STEAM instruction materials for creative engineering design class. PDIE model was used in this study. We developed a STEAM lesson plan and a STEAM lesson worksheet for a total of six sessions through the steps of preparation, development, implementation and evaluation. The validity of the instruction materials was evaluated by the 10 experts using a survey. The instruction materials were applied to the class (52 students attended) of the creative engineering designs unit in technology and home economics subject. The class satisfaction and the creative solving-problem ability were examined after the calss. The class satafacition was high as the average of 10 item was 4.57 (out of 5). The paired t-test was conducted to compare the means of the creative solving-problem ability. It was observed that 'understanding and mastery of knowledge, thought, function and skills in a specific domain', 'divergent thinking', 'critical and logical thinking' and ' motivational factors' were significantly increased after the class. The instruction materials develped in this study were successfully designed to enhance the creative solving-problem ability by designing creative tasks and to intrique the interest by adding visual and auditory stimuli with the Arduino.
