본 연구는 자연수 개념이 역사적으로 전개된 방식을 이해하는 것이 수학적$\cdot$ 교육적으로 매우 중요함에도 불구하고, 그 역사적 고찰이 미진한 상태에 있다는 데에 문제 의식을 갖고 출발하였다. 그리하여 자연수 개념이 역사적으로 어떻게 논의되어 왔는지 살펴보고자 하였다. 수학의 발달 과정에서 수가 어떤 의미를 지녔는지, 문화적$\cdot$사회적 요소가 수 개념을 이해하는 방식과 수 개념의 발달에 어떤 영향을 주었는지 밝힘으로써 자연수 개념에 대한 이해를 풍부하게 하고자 하였다. 그리고 자연수 개념의 역사에 나타난 특징을 드러내고자 하였다.

The first issue was concerning the subject to provide students with an understanding of the principle of light its concept mental factors etc and with the observation and analysis of the light of an object and its form which is the process for designers to be able to deal with the deeper design concept by complementing the setting of necessary concept. The second issue was concerning the process of basic learning about basic electricity and lighting that lighting designers or interior decoration and architecture designer should have such as the introduction of light in kind of light source lighting system and so forth. The third issue was focused on practical affairs such as design and expression techniques the calculation of illumination using the computer simulation and so on. In addition such issues as the history of lighting photograph and its linkage with the field of engineering about new material ware addressed.

The purpose of this study was to assess preschool children's understanding of contagion and their use of immanent justice explanation for illness and accidents, 124 children (66 four-year-olds and 58 five-year-olds) were interviewed individually by two female interviewers. The data were analyzed by ${\chi}^2$ and correlation. Preliminary analyses revealed no significant sex and age differences: Therefore, the data were collapsed across sex and age for all further analyses. The results showed that preschool children have a concept of contagion as a cause of illness, and they understand the effect of distance between people on the likelihood of transmitting contagious ailments. They overextend the concept of contagion to inappropriate ailments: that is, to noncontagious illnesses and to accidents. They employed immanent justice explanations for all illnesses (contagious and noncontagious) and accidents.The use of immanent justice was inversely related to application of the concept of contagion.

Purpose. The purpose of this study was to obtain a clearer understanding of spirituality and examine the process of spirituality through defining the meaning and attributes of spirituality. Method. Concept analysis was done in the three phases, theoretical phase, fieldwork phase, and analytical phase suggested in the Hybrid Model. Five people participated in the fieldwork phase. Results. Spirituality is activated through self-awareness which occurs as spirit being activated through self-introspection, and through restoration of the relationship with Supreme Being. This interconnectedness with Supreme Being has an absolute impact on one's harmonious interconnectedness with self and neighbors, thus leads all the critical attributes of spirituality to be revealed. The core energy of this harmonious inter-connectedness is love. When activated, it has a great impact on an individual as integrative energy, leads one to go beyond everyday experience as well as to have new perspectives, and to live a satisfactory life in every aspect. Conclusion. The results of this study suggest that promotion of connectedness is the most important element in spiritual nursing interventions. The results can also be used effectively in developing spirituality assessment scales and theory.

This article introduces a proposed lesson to help younger or lower level mathematics students conceptualize area. The objective for the proposed lesson was for the student to demonstrate an understanding of the concept of area by identifying the area, in square units, of polygons drawn on computer dot board constructed by computer software, Geometer's Sketchpad. The concept of covering is the key to develop the concept of the area. The article proceeded from rectangular figures, to right-triangular figures, to non-right triangular figures, then to polygons to find the area and develop the formula for the area of the figures. It is meaningful that this kind of materials can be developed within interactive computer environment since students feel successful in loaming and teachers use them directly in their measurement classes.

Fatigue is a universally common word. The subject has been studied in different disciplines, but the basic concept of the term still remains unidentified. It becomes especially important for the medical communications between nurses and clients. Based on the framework outlined by Walker and Avant (1995), this analysis attempts to clarify and examine the symptoms of fatigue. The attributes of fatigue identified in this paper were exhaustion, weighted psychological burden, shortage in capacity or lack of energy, shortage incapacity(motivation and excitement), and imbalance of energy. Therefore, the definition of fatigue refers to a subjective feeling from various internal or external stresses. The consequences of fatigue bring reduced capacity and imbalance of energy. The symptoms show a homeostatic disability or shortage of capacity (physical, psychological, environmental and physiological factors). A precise understanding of "fatigue" will be utilized in defining the causes and measuring outcomes. Also, it will enhance the effective medical communications with client s and nurses. In conclusion, more work is needed to develop objective measurement and effect ivenursing intervention.

The unit fraction is the basis of the fraction concept and has a role of starting point for understanding the fraction concept. In this study, in terms of the importance of the unit fraction, the teaching methods of the fraction based on the unit fraction were explored. First, it was examined the emerging contexts of the fraction concept and the diversity of its meanings. Second, it was investigated the contents of the unit fraction in Korean and CCSSM's curriculum and textbooks. Lastly, I suggested the teaching methods using the unit fraction in terms of the introduction of fraction, fractional operations, and teaching of problem solving based on the unit fraction.

Purpose: This study aimed to perform a concept analysis of quality nursing care. Methods: Walker and Avant's concept analysis method was used to carry out this study. Results: The defining attributes identified were as follows: caring, the nurse-patient relationship, and patient needs. Antecedents included patient characteristics, individual factors (age, education, knowledge, competence, and experience), job position, and environmental factors. The consequences of quality nursing care have significant influence on both patients and nurses. Conclusion: The findings can aid researchers in obtaining a better understanding of quality nursing care, and stakeholders can consider the factors related to quality nursing care and its consequences to improve the nursing process.

개념도는 학습내용에서 주요 개념들을 추출하여 위계적으로 배열하고 그 관계를 나타낸 것이다. 1995년 개정된 제6차 교육과정에서 고등학교 지구과학 검인정 교과서 10종 중 5종의 내용을 분석하고 1종을 선택하여 개념도를 작성하였다. "III. 우주"단원은 지구 밖의 환경을 다루며 별과 우주에 대한 새로운 개념들이 다양하게 제시되며 천문학의 최근 연구들이 소개된다. 교과서에 있는 내용을 Novak의 방법에 의한 개념도를 작성하여 교과서에 있는 개념 중 학습자의 수준에서 개념을 획득하기 위하여 보충되어야 할 개념을 찾고 문제점을 작성하였고 이를 근거로 개선된 개념도를 작성하였다. 다음과 같은 결론을 얻었다. 첫째, 보다 효과적인 이해를 위해 필요없는 소단원명은 제외하고 내용 전개상 관련있는 개념들 간의 연관성을 살린 재배열이 필요하다. 둘째, 상위 개념과 하위 개념의 체계적인 전개가 요구된다. 셋째, 개념들의 학습이 잘 되도록 학습 개념과 관련있는 실례를 찾아 학습자의 경험과 인식에 관련을 맺도록 해야 한다.

In order to confirm ecological validity of D$\ddot{o}$rnyei's second language motivational self, the present study investigated 495 South Korean secondary school students' L2 learning motivation and motivated behavior by using a questionnaire survey. The participants' ideal L2 self, ought-to L2 self, integrativeness, and instrumentality were examined and compared to identify which motivational factor had the most effect on their motivated L2 learning behavior. Among Korean secondary school students, the concept of integrativeness was replaced with the ideal L2 self as a more appropriate concept for understanding Korean secondary school students' L2 learning motivation. As for instrumentality, promotional aspects demonstrated a significant correlation with both the ideal and ought-to L2 selves, whereas preventional aspects showed a relatively high correlation with the ought-to L2 self. The ideal L2 self had the most impact on the motivated behavior, and the ideal L2 self and ought-to L2 self reflected the students' different motivational characteristics. It is suggested that D$\ddot{o}$rnyei's (2005, 2009) L2 motivational self system can be a better psychological model than Gardner's (1985) socio-educational model for understanding Korean secondary school students' L2 learning motivation.
