지식정보화 시대에 있어서 전공교육과 더불어 창의적 인재를 양성하기 위한 창의적 사고 기법 향상에 관한 교육수요가 증가하고 있다. 학생들은 전공과목에 대한 중요성은 인식하고 있지만, 창의성은 선천적으로 타고나야 한다는 선입견이 크게 작용하여 창의성 계발에 별다른 노력을 기울이지 않고 있다. 반면, 기업의 경우 창의력과 응용력을 겸비한 인재를 더욱 중시하고 있다. 이러한 상황에서 러시아에서 개발된 창의적 문제해결기법인 TRIZ는 실무적 적용 가능성이 높은 기법이라고 할 수 있다. 본 연구에서 활용한 TRIZ는 실무문제를 명확히 정의하고 체계적인 분석을 통해 창의적 아이디어를 도출할 수 있는 가이드라인을 제시한다. 창의적 문제 해결 이론에서는 이론적인 내용의 숙지도 중요하지만, 실습을 통한 실무능력의 배양이 필수적으로 요구된다. 본 연구에서는 TRIZ기반 상용 소프트웨어인 CREAX를 활용하여 창의적 문제해결 실습교육을 수행한 결과를 바탕으로 학습자들의 창의적 문제 해결 능력 실습에 필요한 과정을 제안하였다.

이 연구의 목적은 시각에서의 망막 상 이론을 세우는 데 있어 Kepler가 어떻게 과학적 문제를 발견하고 그의 이론 형성 과정에서 어떻게 귀추적 사고를 하였는가를 조사하고, 그 분석 결과를 통해 과학에서의 창의성 교육을 위한 시사점을 얻는 것이었다. 관련 문헌들의 심층적인 분석을 통해, Kepler의 망막 상 이론에서의 과학적 문제 발견은 당시 시각 이론에 대한, 그의 정확하고 적절한 광학적 지식을 바탕으로 한 비판적 분석으로부터 이루어졌으며, 그는 새로운 이론을 세우는 과정에서 이미 알고 있는 구면 렌즈에서의 광학적 현상을 눈의 메카니즘 설명에 도입함으로써 귀추적 사고의 과정을 거쳤음이 밝혀졌다. 이러한 결과들로부터 과학 창의성 교육을 위한 시사점이 다음과 같이 도출되었다. 첫째는, 과학 창의성교수 자료의 개발에 있어서 프로그램 속에 Kepler의 과학적 문제 발견과 같은 상황이 제시될 필요가 있다는 것이며, 둘째로는, 적절하고 정확한 과학적 지식이 과학적 문제를 발견하고 가설을 형성하는 데 있어 필수적이라는 것이 지도되어야 하고, 마지막으로는, 학생 스스로 성공적인 문제 해결 경험을 가질 수 있도록 하고, 그것이 그들로 하여금 새로운 과학적 문제를 발견하는 데까지 이르도록 프로그램을 구성해야 한다는 것이다.

This paper focuses on the usage of the fuzzy set theory in decision making systems. The approach to calculation of generalized membership function, based on application of method of principal components is proposed. For solving of the problem of fuzzy forecasting the development of Bayes procedure is used. The structure of decision making system, in which following procedures are fulfilled, is discussed.

This study reviews the process of creating the patterns through the Christopher Alexander's books to discover the fundamental rules for creation of the pattern language. The essential ideas of 11 rules describing the characteristics of the pattern language are organized by keyword depending on the characteristics of each rule. Then, this study analyzes which keyword was applied importantly and how it had been developed chronologically in the Alexander's books. As a result, 5 keywords - reflection of cultural difference, reflection of human desires, solving the repeated problem, function suitable for principal purpose, and network structure - are applied to his early books in which the pattern language was theoretically developed, the pattern of traditional society was discovered and the network structure was developed. Another 5 keywords - user participation method, new problem solving, structure preserving transformation, post-mechanization method, and central invariant structure - are applied to the books in his mid-term after completion of the pattern theory which discover new pattern for contemporary society and apply the pattern language to time and space. In his later books which organize the theory of pattern language and suggest the direction for using the pattern language, 5 keywords - wholeness, post-mechanization method, user participation method, new problem solving, and structure preserving transformation - are applied. Users may use the pattern language more precisely if he/she considers the keywords of the early period in searching the patterns of existing environment, the keywords of the intermediate period in searching the patterns of new environment or in regard to time and space, and the keywords of the later period in considering direction of the application of the pattern language.

Background: In this study, the Capstone Design was applied to the clinical dental hygiene course of the Department of Dental Hygiene, and its effect was confirmed by qualitatively evaluating the students' reflection on the capstone design class experience. Methods: This study was conducted for the "Clinical Dental Hygiene and Practice III" course, in which third year students develop the ability to judge and plan dental hygiene based on problem-solving ability and critical thinking. By applying the Capstone Design within the core curriculum of the class, the students analyzed problems based on their major knowledge of dental hygiene in order to improve their ability to manipulate periodontal instruments, and focusedon the process of developing the contents of periodontal instruments by using them. Results: The application of Capstone Design on clinical dental hygiene and practice III classes increased students' active class participation, and through the problem-solving process, students' learning and confidence improved. Conclusion: The Capstone Design can be viewed as a teaching method that promotes the participation of students in the dental hygiene department and can effectively help their learning and confidence through a problem-solving process.

There have been many approaches to solve the disturbance rejection problem in the control of LTI systems with state independent disturbances or possibly nonlinear state dependent disturbances. From the view point of each actuator, robot manipulators can be modeled as the second class of systems. With this model, M.Nakao et al. [1] introduced a decentralized control scheme based on interference estimation which is simple in its implementation and robust to the coupled dynamics and parameter variations. This paper systematically generalizes the control scheme to arbitrary finite dimensional LTI systems with disturbances. In doing so, we develop a disturbance observer theory for solving the disturbance rejection problem. We also present a discrete version of the theory with discussion of sampling and time-delay effects.

A four-noded plate bending quadrilateral (PBQ4) and an eight-noded plate bending quadrilateral (PBQ8) element based on Mindlin plate theory have been adopted for modeling the thick plates on elastic foundations using Winkler model. Transverse shear deformations have been included, and the stiffness matrices of the plate elements and the Winkler foundation stiffness matrices are developed using Finite Element Method based on thick plate theory. A computer program is coded for this purpose. Various loading and boundary conditions are considered, and examples from the literature are solved for comparison. Shear locking problem in the PBQ4 element is observed for small value of subgrade reaction and plate thickness. It is noted that prevention of shear locking problem in the analysis of the thin plate is generally possible by using element PBQ8. It can be concluded that, the element PBQ8 is more effective and reliable than element PBQ4 for solving problems of thin and thick plates on elastic foundations.

It is proved that $k[X_1,{\ldots},X_v ]$ localized at the ideal ($X_1,{\ldots},X_v$ ), where k is a field and $X_1,{\ldots},X_v$ indeterminates, is not weakly quasi-complete for $v{\geq}2$, thus proving a conjecture of D. D. Anderson and solving a problem from "Open Problems in Commutative Ring Theory" by Cahen, Fontana, Frisch, and Glaz.

Normality is one of the most common assumptions made in sampling and statistical inference procedures without suffering from lack of attention. Its results may lead to an invalid conclusion. We present several testing procedures that can be used to evaluate the effects of departure from normality using concrete examples by hand or with the aid of Minitab. The goal is to influence prospective teachers in order to learn statistical concepts and techniques for testing normality on the basis of the didactical theory.
