본 논문에서는 비 개념이 역사적으로 어떤 의미를 가지고 있으며, 비에 대한 생각이 어떻게 변화되어 왔는지 살펴본다. 또한 비에 대한 여러 가지 수학적 의미를 찾아보고, 비 개념의 본질이 어떠해야 하는지를 알아본다. 그리고 비례적 추론의 직관적 근원과 발달 과정을 찾아보고 비 개념의 심리적 측면을 분석해 봄으로써 비 개념 지도와 관련하여 교육적 시사점을 탐구한다.

본 연구는 학습자의 학습과정과 학습내용, 평가내용을 분석하여 학습내용 중에 이해가 안된 부분이 있거나 문제가 있는 부분을 진단하고 이에 적절한 학습 조언을 제공함으로써 학습의 효과를 높일 수 있도록 하는 적응형 교수 시스템을 제안한다. 학습자의 학습내용 중 한 개념에 대한 학습은 다른 개념의 학습에 영향을 미치며, 한 개념을 학습하기 위해서는 그 개념에 대한 선행개념을 충분히 이해하고 있어야 된다는 점을 고려하여 학습내용을 구성시 컨셉맵을 기반으로 학습개념간의 관련성을 표현하고 있다. 이러한 컨셉맵을 통해 한 개념을 학습하기 전 요구되는 선행개념에 대한 학습 정도를 파악하여 이에 따른 적합한 학습내용을 제공하고, 평가문항과 학습개념과의 관련도를 이용하여 학습자의 학습내용 중 문제 있는 부분을 진단하여 적절한 조언을 제공한다.

초등학교 수학에서 지도하는 기하 내용 중 중요한 것 중의 하나가 도형을 시각적인 외양만을 가지고 바라보는 것이 아니라 도형의 구성요소와 성질을 가지고 파악하도록 지도하는 것이다. 따라서 본 연구에서는 초등학교에서 평행과 평행선에 관한 고찰하여 보았다. 학생들이 평행선에 관하여 잘못된 개념 이미지를 갖게 된 이유 중의 하나가 교과서에 제시된 예들로 보이며, 두 직선이나 선분이 평행한지 여부를 판단하는 방법에 대한 지도가 미흡하며, 이를 개선하기 위해서는 두 선분이나 직선이 평행한지를 판단하는 방법이 필요하며, 특히 초등학교 수학에서는 모눈종이 위에 그려진 두 직선의 평행여부를 판단하는 방법을 지도하는 것이 필수적으로 필요함을 살펴보았다. 이를 바탕으로 두 직선이나 선분이 평행한지 여부를 판단하는 방법을 지도하는 구체적인 방안을 제시하였다.

The purpose of this study to gather information on demographic statistics, children’s attachment to their mothers, and daily stress variants in order to assess their effects on child’s self-concept and depression within multi-ethnic familiy settings. A questionnaire survey was used to targeted 3rd, 4th, 5th and 6th graders in elementary schools in Jeonnam. A total of 158 children were surveyed. SPSS for Windows 12.0 was used to carry out descriptive, and comparative statistical analysis such as Cronbach's $\alpha$, correlations analysis, and a hierarchical regression analysis. Result showed that the most significant variant affecting self-concept among children from multi-ethnic families was attachment to their mothers. Other related individual variants were in order of importance, communication skills, feelings of alienation, and mothers’ nationalities. The variant most responsible for having an affect on depression among children from multi-entnic families was the attachment to their mothers. Other related individual variants were in order of importance, feelings of alienation, stress from peer relationships, mothers’ nationalities, and stress from economic and physical environments.

Objectives : The purpose of this study was to provide information about Maumgongbu to meet the needs of people by analysing the concept of Maumgongbu in group counseling. Methods : This study was conducted using Walker and Avant's Concept Analysis Strategy. Dictionaries, Wonbuddhism's Kyunjions and literatures, and participants' journals were reviewed after enrolling in Onsarm maumgongbu group counseling. Results : The attributes of the Maumgongbu include emotion, object, self-reflection, attribution, and creativity. The antecedents of "Maumgongbu" are the conditions arising from negative emotions. The Maumgongbu helps people find the emotional causality of their inner self by self-reflecting, getting out of false belief, restoring positive emotions, maintaining healthy and warm relationships with oneself, family, friends and society. Above all, the Maumgongbu makes people experience tranquility and true happiness and activate their positive energy or power. Conclusions : If there is a clear indication of linkage to principles, attributions, precedents and consequences, and empirical referents to any of Maumgongbu programs, there is no doubt that our understanding of the human mind and lives will be greatly enriched. Furthermore, self-discipline and steadfast complements give us calmness, peacefulness and better quality of life.

Purpose: The purpose of this study was to define and clarify the concept of reality shock in new graduated nurses. Methods: The hybrid model was used to develop the concept of reality shock. The model included a field study. The participants were 9 newly graduated nurses with a nursing career spanning less than a year. Results: The reality shock in newly graduated nurses was identified to have three dimensions and seven attributes. Specifically: 1) the dimension of performance included two attributes (conflict between theory and practice, and being overwhelmed by the workload), 2) the dimension of relationship included three attributes (loss of support, embarrassment from interference, and relational withdrawal), 3) the dimension of expectations included two attributes(value confusions and incongruity in personal life). Conclusion: Newly graduated nurses' reality shock was defined as a state of incongruence in their entire life that the new nurses experienced owing to value confusions that occurred due to the conflicts between theory and practice in an unfamiliar work environment, getting overwhelmed by the workload, and withdrawing establishing relationships with others due to the loss of support and excessive interference. These findings could help develop intervention strategies to decrease reality shock in newly graduated nurses.

정보 검색은 사용자가 필요로 하는 요구에 가장 적합한 정보를 검색할수 있어야 한다. 정보 검색에서 질의어가 문서에 대하여 어느 정도의 유사성을 가지고 존재하는냐를 기준으로 문서를 순서화 할 때, 실제 순서화된 문서들을 보면 질의어와는 다른 문서들이 순서화 되는 경우를 볼 수 있다. 따라서 본 논문에서는 확장 퍼지 개념 네트워크에 근거 문서 검색을 위한 순의 결정 방법을 제안한다. 확장 퍼지 개념 네트워크에는 개념들 사이에 4가지의 퍼지 관계가 있다. 퍼지 양의 조합, 퍼지 음의 조합, 퍼지 일반화, 및 퍼지 세분화등이 있다. 확장 퍼지 개념 네트워크는 관계 행렬과 관련 행렬로 모델화 하여, 유사도 측정을 하였다.

Prioritizing the design specifications among many alternatives is necessary at the stage of concept design. Design specifications have trade-offs between cost and performance, and the relationships among them, in the standpoint of various functional requirements, are complex. AHP(Analytic Hierarchy Process) method is one of the most popular ways of solving the priority setting problem. However, it is impossible to monitor the interim findings in the middle of the process, it is hard to predict the difference when changing pairwise comparison conditions, and the operation done by one person makes it hard to share the process simultaneously. This paper shows a new method of priority setting in this kind of decision making problem. This method is designed to support the realtime priority setting among many design specifications with regards to many functional requirements. A new algorithm and visualization methods are introduced, and the usability is verified in an exemplary concept design stage.

Concepts of science have been developed by occupying 'ecological niche' within conceptual ecology. The ecological niche is determined from the mutual effect between intellectual environmental of the learner and new concept, which few studies have been conducted. This study examined how the ecological niche of the concept of photosynthesis in $7^{th}$ grade is changed by instruction. The ecological niche was analyzed using 2 methods: (1) the change in the diversity of concepts, and (2) the change in the proximity of concepts based on the frequency and the relativeness score of the concepts. The concept of photosynthesis was analyzed in the 4 domains in the place of photosynthesis, products of photosynthesis, reactants of photosynthesis, and environmental factors. The results of this study are as follows: (1) reduced diversity of concepts, (2) increased frequency and relativeness score of the scientific concepts, and (3) increased proximity of the scientific concepts by instruction. With these results, the mutual effects of the concepts within the conceptual ecology have become active by class to differentiate the relationships between the concepts, which accordingly displayed their changes in status.
