2007년 개정된 중학교 정보 교육과정은 현 7차 컴퓨터 교육과정과 많은 차이를 가지고 있다. 2007년 개정된 정보 교과 교육과정은 응용 소프트웨어 사용에서 벗어나 컴퓨터 과학의 원리와 문제해결능력을 중심으로 구성하였다. 개정된 정보 교육과정에는 7차 교육과정의 교육내용에 포함되어 있지 않은 '문제 해결 방법과 절차' 영역을 포함하고 있기 때문에, 이 영역의 성취기준 및 경가기준이 필요하다. 본 연구는 개정된 중학교 정보 교육과정의 교수학습방법과 평가 방법의 가이드라인을 제시하고자 '문제 해결 방법과 절차' 영역의 성취기준 및 평가기준을 설정하였다.

Problems solved by the TRIZ method have been developed and applied in many fields ranging from management as well as engineering. Most of the problems occurring in the construction site should be applied immediately. To solve the problem of building engineering, formulation of the problem solving process using the TRIZ method is needed. This study classified and analyzed the problem solving process of architectural engineering technology in accordance with the procedures of TRIZ, and showed the case of solving problem in the field and the availability of TRIZ theory in architectural engineering. This paper shows that the TRIZ theory can be used as a tool for creative problem solving and cost reduction in architectural engineering.

A method is described for the solution of a linearly constrained program with parametric nonlinear objective function. The algorithm proposed in this paper may be regarded as an extension of the simplex method for parametric linear programming. Namely, it specifies the basis at each stage such that feasibility ana optimality of the original problem are satisfied by the optimal solution of the reduced parametric problem involving only nonbasic variables. It is shown that under appropriate assumptions the algorithm is finite. Parametric procedures are also indicated for solving each reduced parametric problem by maintaining the Kuhn-Tucker conditions as the parameter value varies.

Purpose: The purpose of this study was to investigate factors which influence the process of problem solving in nursing students during clinical practice. Method: Data were collected by questionnaires from 511 nursing students in from April 10 to June 10, 2011. Data were analyzed by Pearson's correlation coefficients and multiple regression procedures. Result: The values regarding self-leadership (mean 3.62), self-directed learning readiness (mean 3.53) and problem solving process (mean 3.37) were higher than the median. There were significant correlations between all the predictive variables and the process of problem solving. The greatest factors influencing the process of problem solving in nursing students were self-leadership and self-directed learning readiness (54.3%). Conclusion: By using the results of this study as a foundation, nursing education curriculum should be comprised of self-leadership and self-directed learning readiness for improvement of nursing students' problem solving process.

정보 교과는 지식정보화 사회에 필요한 정보 활용 능력은 물론 창의적인 문제해결력을 함양하기 개설된 교과이다. 그러나 창의적 문제해결요소가 교과서에 어느 정도 포함되었는지를 분석하는 연구는 미미하다. 따라서 본 논문은 중학교 정보 1 교과서 '문제해결방법 및 절차' 영역의 창의적 문제해결력 경향을 정량적으로 분석하였다. 정보 교과서가 창의적 문제해결력 함양 요소를 어느 정도 포함하고 있는지 최길수의 정량적 분석법으로 분석한 결과, 교과서별로 문제해결과정 반영과 문제해결전략 제시의 충실도에 차이가 크게 나타났고 모든 교과서가 활동 요구 지수, 창의적 문제해결력 관련지수, 활동 유형지수가 전체적으로는 바람직한 범위에 있으나 소 영역별로는 바람직한 범위를 벗어난 것이 있는 것으로 나타났으며 지수 값이 균형을 이루지 못한 교과서가 있고 활동 유형이 일부 유형에 치우쳐 있는 것으로 나타났다. 그러므로 앞으로 정보 교과서의 개발 및 수정 보완 시 문제해결과정 반영과 문제해결전략의 충실도를 높이고, 교과서의 학습 활동 구성 시 다양한 학습 활동 유형을 활용하고 기본 정신 기능과 고등 정신 기능을 요구하는 활동 비율의 균형을 유지할 것을 제안하였다.

This study is a study to collect information about 'Limitations of functions' related learning. Especially, this study was conducted on three students who can find answers by algebraic procedure in the process of extreme problem solving. Students have had the experience of converting from their algebraic procedures to graphical expressions. This shows how they reflect on their algebraic procedures. This study is a study that observes these parts. To accomplish this, twelfth were teaching experiment in three high school students. And we analyzed the contents related to the research topic of this study. Through this, students showed the difference of expressions in the method of finding limits by using algebraic interpretation methods and graphs. In addition, we examined the connectivity of the limitations of functions problem solving process of functions using algebraic procedures and graphs in the process of converting algebraic expressions to graph expressions. This study is a study of how students construct limit concepts. As in this study, it is meaningful to accumulate practical information about students' limit conceptual composition. We hope that this study will help students to study limit concept development process for students who have no limit learning experience in the future.

This paper presents a numerical procedure for solving initial-value problems using the special functions which belong to a class of Rvachev's basis functions $R_{bf}$ based on algebraic and trigonometric polynomials. Because of infinite derivability of these functions, derivatives of all orders, required by differential equation of the problem and initial conditions, are used directly in the numerical procedure. The accuracy and stability of the proposed numerical procedure are proved on an example of a single degree of freedom system. Critical time step was also determined. An algorithm for solving multiple degree of freedom systems by the collocation method was developed. Numerical results obtained by $R_{bf}$ functions are compared with exact solutions and results obtained by the most commonly used numerical procedures for solving initial-value problems.

The IPSAP which is a finite element analysis program has been developed for high parallel performance computing. This program consists of various analysis modules - stress, vibration and thermal analysis module, etc. The M orthogonal block Lanczos algorithm with shiftinvert transformation is used for solving eigenvalue problems in the vibration module. And the multifrontal algorithm which is one of the most efficient direct linear equation solvers is applied to factorization and triangular system solving phases in this block Lanczos iteration routine. In this study, the performance enhancement procedures of the IPSAP are composed of the following stages: 1) communication volume minimization of the factorization phase by modifying parallel matrix subroutines. 2) idling time minimization in triangular system solving phase by partial inverse of the frontal matrix and the LCM (least common multiple) concept.

The objective of this paper is to develop the efficient heuristic method for solving the minimum makespan problem of the job shop scheduling. The proposed heuristic method is based on a constraint satisfaction problem technique and a improved randomizing search algorithm. In this paper, ILOG programming libraries are used to embody the job shop model, and a constraint satisfaction problem technique is developed for this model to generate the initial solution. Then, a improved randomizing search algorithm is employed to overcome the increased search time of constrained satisfaction problem technique on the increased problem size and to find a improved solution. Computational experiments on well known MT and LA problem instances show that this approach yields better results than the other procedures.

본 논문은 학생들이 모둠을 만들어 모둠원 간의 협의를 통해 문제를 만들고 문제를 해결하는 방법인 브레인라이팅 기법을 활용한 문제제기 수업 통하여 수학적 문제해결력과 창의력 신장에 미치는 효과를 알아보고, 흥미도 검사지를 통해 브레인라이팅기법에 의한 수학학습 수업이 기존의 수학학습과 어떠한 차이가 있었는지 알아보고자 했다. 실험결과 브레인라이팅 기법을 활용한 문제제기 수학학습이 문제해결력의 신장과 창의력의 하위 요소인 유창성과 독창성 신장에 효과가 있다는 것을 알 수 있었고, 브레인라이팅 기법을 활용한 문제제기 수학 학습이 학생들의 흥미도가 올라감에 따라 학생들이 문제를 풀이하는 과정에서 모둠원간의 협의 하고, 해결하는 과정에서 자신감이 높아졌음을 알 수 있었다.
