Most of people who are engaged in research and development find it difficult to solve the engineering problems creatively due to the lack of ideas. There are two famous methods for inventive problem solving: ＆apos;Brainstorming＆apos; and ＆apos;TRIZ＆apos;. Brainstorming is the most popular tool until now to find a creative solution and TRIZ is not so popular yet but leads us to a very useful and clear solution. These two methods whose goals are the same usually take quite different routes to the final solution; Those routes have their own unique advantages and disadvantages. In this paper, a creative problem solving method optimized by correlating Brainstorming and TRIZ is proposed. And this method demonstrates how rough initial ideas can be quickly refined and how a problem can be solved correctly.

Grid system has the potential to resolve the current need of bioinformatics for super-computing environment inexpensively. There are already several Grid applications of bioinformatics tools. To solve the real-world bioinformatics problems, however, the various integration of each tool is necessary in addition to the implementation of more basic tools. Workflow based problem solving environment can be the efficient solution for this type of software development. There are still heavy overhead, however, to develop and implement workflow model on current Grid system. He re we propose a model of simple problem solving environment that enables component based workflow design of integrated bioinformatics applications on Grid environment by using Condor functionalities. We realized this model for practical bioinformatics solutions of a genome sequence analysis and a comparative genome analysis. We implemented necessary bioinformatics tools and interfacing tools as the components, and combine them in the workflow model of each solution by using the tools presented in Condor.

본 연구는 공학설계 교육을 통해 진행되는 개념설계와 제품설계의 문제해결과정이 학생들의 자기주도학습 능력 향상에 어떠한 영향을 미치는지 구명하는데 목적이 있다. 이를 위해 입문설계교육을 수강한 학생들을 대상으로 심층면담을 실시하였는데, 이를 통해 도출된 주요 연구결과는 다음과 같다. 첫째, 문제해결과정을 통해 학습욕구를 진단하고 해결해야 할 문제를 정의하는 것의 중요함을 깨닫게 되었다. 둘째, 문제정의 후 문제해결을 위한 학습계획을 구성하고 이를 체계적으로 수행해 나가는 것이 중요함을 인지하게 되었다. 셋째, 문제해결을 진행하는 과정에서 지속적인 수정 보완이 필요함을 알게 되었고, 과정 종료 후에도 평가 및 점검이 필요하다는 사실을 인지하게 되었다. 이러한 결과를 토대로 볼 때 설계 교육의 문제해결과정은 학생들이 자기주도적으로 학습하는데 긍정적인 영향을 미치고 있음을 알 수 있었다.

This study was conducted to explore the applicability and effects of Smart Support System for Creative Problem Solving(S3CPS) in engineering education. S3CPS is an online system developed to support learners' creative problem solving activities based on the CPS model proposed by Treffinger et al.(2000). In this study, it was applied in an engineering course in which students work in teams to design and produce creative robots with the purpose of verifying its effects on creative problem solving and team projects. To address the purpose, interviews and surveys were carried out to examine the effects of S3CPS. The qualitative data were analyzed through a generic coding process. Three ways to apply S3CPS in an engineering course based on team project were derived and effects of the system were also analyzed. It implies that specific design guidelines are required for the optimal use of the system for existing engineering courses.

본 연구는 컴퓨팅사고력 강좌의 문제해결능력을 파악하고 분석한 자료로 소프트웨어 교육 계획에 반영하기 위하여 분석되었다. 학습자를 대상으로 문제해결능력에 관한 사전·사후 설문을 진행하여 학습자의 어려운 점을 측정해, 소프트웨어 교육 방안을 모색하였다. 본 연구를 위하여 수업 주제와 내용 범위 및 활동 계획을 주당 2시간씩 15차시 분량의 소프트웨어 교육과정으로 구성하였고, 수강생 63명을 대상으로 설문을 하였다. 연구 결과는 소프트웨어 교육을 통한 문제 해결 능력 향상의 폭이 '이공계열 학과'보다도 '인문계열 학과'가 더 높게 나타났다. 본 연구 결과를 토대로, 창의 융합형 인재 양성을 위하여 사고나 인식을 근본적으로 규정하는 이론적 체계가 서로 융합하여야 한다. 또한, 향후 소프트웨어 교육이 다양한 분야의 비전공자 대상까지 확대되도록 개선해야 한다.

비전공 학부생을 대상으로 SW 교육을 시행하는 대학들이 점차 늘어가고 있다. 그러나 비전공 학생들에게 컴퓨팅적 사고 과정을 교육하는 데 어려움들을 겪고 있다. 본 논문에서는 이러한 문제를 개선하기 위하여 수학적 연산 문제를 활용하지 않았다. 그리고 간단한 피지컬 교구를 활용한 컴퓨팅적 사고기반 기초 문제해결과정 교육방법을 제안하였다. 제안한 교육방법에서는 아두이노 보드를 사용한 LED 회로를 예로 들어 교육한다. 그리고 컴퓨팅적 사고에 의한 문제해결과정을 설명한다. 이를 통해, 추상화, 문제 분해, 패턴인식과 알고리즘이라는 핵심 컴퓨팅적 사고과정을 학습한다. 제안한 교육방법을 적용하면, 학생들이 주어진 문제를 이해하고 분석하는 데 어려움 없이 컴퓨팅적 사고과정의 개념과 필요성을 습득하는 성과를 얻을 수 있다.

This paper proposes an augmented Lagrange Hopfield network (ALHN) based method for solving multi-objective short term fixed head hydrothermal scheduling problem. The main objective of the problem is to minimize both total power generation cost and emissions of $NO_x$, $SO_2$, and $CO_2$ over a scheduling period of one day while satisfying power balance, hydraulic, and generator operating limits constraints. The ALHN method is a combination of augmented Lagrange relaxation and continuous Hopfield neural network where the augmented Lagrange function is directly used as the energy function of the network. For implementation of the ALHN based method for solving the problem, ALHN is implemented for obtaining non-dominated solutions and fuzzy set theory is applied for obtaining the best compromise solution. The proposed method has been tested on different systems with different analyses and the obtained results have been compared to those from other methods available in the literature. The result comparisons have indicated that the proposed method is very efficient for solving the problem with good optimal solution and fast computational time. Therefore, the proposed ALHN can be a very favorable method for solving the multi-objective short term fixed head hydrothermal scheduling problems.

The study was conducted to develop two parallel short forms for the Convergent thinking and Problem solving questionnaires which are part of H University's core competency diagnostic tools, based on Multi-Item Response Theory. Item responses of 2,580 students were analyzed using Graded Response Model(GRM) to determine item difficulty and discrimination of each item. The research results are as follows. Two parrallel short tests were developed for the Convergent thinking questionnaire consisting of 12 items which were originally 17 items. Likewise, the Problem solving questionnaire, which originally consisted of 15 questions, was divided into two parallel short forms, each consisting of 9 items. The reliability of the shortened parallel tests was confirmed through internal consistency analysis, and their similarity to the original tests was established through correlation analysis. This study contributed to quality management of competency-based education and programs at H University by developing shortened tests. Based on the results, implications were presented as well as limitations and discussions.

TRIZ, the Russian acronym for Theory of Inventive Problem Solving(TIPS) is introduced in this paper. The core concepts of TRIZ such as levels of inventions, patterns of technological evolution, technical and physical contradictions are explained. It is also discussed that how TRIZ can be applied to quality function deployment in order to overcome negative correlations(i.e., trade-off relationships) between engineering characteristics. Some case examples are presented for the purpose of explanation.
