학생들은 개념과 관련된 여러 가지 기하적 표현 중에서 특정한 표현을 해당 개념의 형식적인 정의에 우선하는 기하적 심상으로 받아들이곤 한다. 학생이 지닌 기하적 심상과 개념의 형식적인 정의가 항상 조화를 이루지는 않으며, 이로 인해 문제해결과정에서 오류가 유발될 수 있다. 기하적 표현을 통한 학습이 중요한 비중을 차지하는 기하 영역에서는 이러한 학생들의 오류 및 오류의 원인을 체계적으로 분석할 필요가 있다. 본 연구에서는 학생이 지닌 특정한 기하적 심상으로 인해 발생하는 오류 사례의 분석을 통해 보다 일반적으로 학생들이 수학적 개념에 대하여 지니는 심상 및 심상과 관련한 오류의 유형을 개념적으로 분류하여 이론적 분석의 틀을 제안하고자 한다.

Recently the concept of 'empowerment' not only attracts attention in the area of management but also is considered as an useful concept in the areas of nursing theory. practice, education, and research. The purpose of this paper is to clarify the meaning of the concept 'empowerment'. More concretely, it is to find the concept that can be applied appropriately to the area of nursing management. This study uses Walter & Avant's(1983) process of concept analysis. The attributes of empowerment based on the concept can be defined concisely as follows : 1. a dynamic and interaction process 2. a partnership which values self and others : power shaving 3. mutual decision-making using resources, opportunities, and authority 4. accept autonomy and responsibility Antecedents of empowerment consist of 1) mutual trust and respect, 2) education and support, 3) participation and commitment. In regard to the consequences of empowerment, it is expected to 1) positive self-esteem, 2) ability to set and reach goals, 3) the promotion of organization's effectiveness and productivity, 4) provide effective and high quality health-care, 5) a sense of hope for the future. The concept of empowerment is certainly believed that it will help future nurses since they needs an integrated technique that can treat acute and chronic patients' nursing, individuals, families, and communities. Therefore. it is necessary to develop the instrument including the defining attributes identified in this study. Also, it is need follow up study of this concept.

The writer has made efforts to solve the weaknesses of the traditional systems through reconstructing cost information systems by introducing 'logical circuit concept' instead of account. As the new designed systems also allow the basic thought of double entry, they are compatiable with the traditional ones. For this, the writer included both monetary and physical information in the systems, replaced the concept of debit & credit with the concept of inputs & outputs, and changed transfer concept between accounts based on reverse logic into flow concept between unit systems based on proceeding logic.

The concept field is defined as the schema of all equivalent definitions of a mathematics concept. Concept system is defined as the schema of a group concept network where there are mathematics relations. Proposition field is defined as the schema of all equivalent proposition sets. Proposition system is defined as a schema of proposition sets where one mathematics proposition at least is "derived" from the other proposition. CPFS structure that consists of concept field, concept system proposition field, proposition system describes more precisely mathematics cognitive structure, and reveals the unique psychological phenomena and laws in mathematics learning.

This study examined the moderated mediating effect of stress by self-concept on the influence of ego-resiliency on school adjustment in children. The participants consisted of 278 4th-graders, who completed self-report questionnaires designed to assess ego-resiliency, school adjustment, self-concept, and stress. The results indicated the following: First, stress mediated the effect of ego-resiliency on school adjustment. Second, self-concept moderated the effect of stress on school adjustment. Third, the mediating effect of stress on the influence of ego-resiliency on school adjustment was moderated by self-concept. The mediating effect of stress was statistically significant when self-concept was positive, but was not statistically significant when self-concept was negative. Methods to improve children's school adjustment are also included, based on the results of this research.

In this paper we consider the equality sign as a mathematical concept and investigate its meaning, errors made by students, and subject matter knowledge of mathematics teacher in view of The Model of Mathematic al Concept Analysis, arithmetic-algebraic thinking, and some examples. The equality sign = is a symbol most frequently used in school mathematics. But its meanings vary accor ding to situations where it is used, say, objects placed on both sides, and involve not only ordinary meanings but also mathematical ideas. The Model of Mathematical Concept Analysis in school mathematics consists of Ordinary meaning, Mathematical idea, Representation, and their relationships. To understand a mathematical concept means to understand its ordinary meanings, mathematical ideas immanent in it, its various representations, and their relationships. Like other concepts in school mathematics, the equality sign should be also understood and analysed in vie w of a mathematical concept.

It aims to understand how the time can be expressed in architecture from viewpoints of Oriental and Western philosophy. We just have done sporadic studies such as historical time, physical time, specific time, time as the space-time continuum and appreciation time. It`s impossible to find out that time exactly is since `time` is ambiguous. Because the meaning is formed newly by relational changes between visible and invisible existing thing. In such point of view, this study attempts at analyzing the inter-relationship between the art, music, architecture and time-concept in oriental and western philosophy. A comparative study follows : Time can be classified into the linear concept of time & the cyclic concept of time in an agricultural civilization and oriental philosophy. Linear concept of time can be divided into 1)the inevitable concept of time and 2)the 4-dimensional concept of time and 3) the indefinite concept of time.

The purpose of this study is to analyze the Daniel Libeskind' spatial concept in view of the Merleau-Ponty's Phenomenology. After the coming of postmodern architecture, the concept of space ceased to be discussed between architects. Instead a sign and a form were supposed as much more important subject to define architectural discipline. But after 1980, the new concept of architectural space was experimented by the architects like Frank Gehry, Peter Eisenman, Steven Hall, and Bernard Tschumi, which was clearly distinguished from modern spatial concept. By the Daniel Libeskind' architecture, this study are to make clear this tendency. For this, we accept as an important instrument Meleau-Ponty's phenomenology and the spatial concept of Minimalism, which stress the relationship of inter-subjectivity between space and human body. Consequently, Daniel Libeskind' spatial concept is characterized by fragmental, accidental, heterogeneous space by accidental events which is occurred by movement of human, which was indentified with Merleau-Ponty's spatial concept.

Purpose: The purpose of this study was to explore the experiences of nursing students in Korea who used concept mapping for understanding pathophysiology. Methods: The data were collected using an open-ended questionnaire from 83 sophomore nursing students after studying concept mapping in pathophysiology class. Each group consisted of five nursing students submitting four concept maps regarding cell injury, inflammation, infection, and neoplasm. After familiarity with concept mapping, the participants wrote their experiences anonymously on sheets of paper. The submitted materials were analyzed via qualitative content analysis. Results: The collected materials were classified into 3 themes, 8 categories, and 18 subcategories. Three themes emerged: (1) awareness of capabilities, (2) difficulties of completion, and (3) benefits of application. Conclusion: The study revealed that participants experienced self-capabilities, and the difficulties and benefits of concept mapping. Concept mapping also provided the opportunity for nursing students to realize communication skill improvement by active group discussion within a group.

It is not easy to find desired information in the world wide web. In this research, we introduce a notion of concept network that is useful in finding information if it is used in search engines that are specialized in domains such as medicine, law or engineering. The concept network that we propose is a network in which nodes represent significant concepts in the domain, and links represent relationships between the concepts. We may use the concept network constructor as a preprocessor to speci-alized search engines. When user enters a target word to find information, our system generates and displays a concept network in which nodes are con-cepts that are closely related with the target word. By reviewing the network, user may confirm that the target word is properly selected for his intention, otherwise he may replace the target word with better ones discovered in the network. In this research, we propose a detailed method to construct concept net-work, implemented a prototypical system that constructs concept networks, and illustrate its usefulness by demonstrating a practical case.
