The purpose of this study was to investigate conception of children's hospitalization stress and to make clear concepts, and to use Walker & Avant's concept analysis method. Children's hospitalization stress attributes were derived from physiological changes, individual-environmental interactions, cognitive and psychosocial developmental stage responses, and intrinsic and outward changes due to coping styles. The prerequisites for hospitalization stress of children were disease severity, biological factors, and support system, and the results were hospitalization adaptation, disease and health recovery, improvement of child development, and acquisition of coping skills. In order to solve the prerequisites for Hospitalization stress of children, it is necessary to be aware of the disease and to establish a support system of parent-family. Afterwards, we suggest more qualitative research on the hospitalization stress of children, the development of tools that reflect the characteristics of the hospitalization stress of children, and the development of programs to solve the Hospitalization stress.

Since 1990, descriptive studies about the concept of client advocacy have been published in the health journals. However, empirical studies of the concept are still lacking. There are not enough bases to apply the concept of client advocacy in nursing practice. The purpose of this paper is to encourage empirical research about client advocacy by clarification of the concept and to discusses application of the theory in child healthcare. The literature was reviewed that empirical studies on client advocacy conducted after the year 2000. The changing trends in the client advocacy concept was examined; it was changed from the philosophical concept to nursing action and changed from individual advocacy to collective advocacy, with the rise of the self advocacy concept. The research trends on client advocacy evolves from descriptive study to quasi-experimental study and instrument development study, with diversification and expansion of research methods, advocates, clients and settings. The advocacy role of the nurse in child healthcare is significant due to the child's lack of self determination ability. In ill child care, the application of individual advocacy is potent, while in healthy child care, collective advocacy, policy advocacy, and social advocacy is effective.

In this study, pre-service elementary teachers (n=68) participated in an inquiry of exploring children's science ideas as group work. After conducting interviews with children, the pre-service teachers analyzed their science ideas on specific concept and propose a teaching plan based on their findings. This paper aimed to find the positive learning experiences of the pre-service teachers by looking into their inquiry process. Questionnaire, researcher's journal, classroom videos and final reports were collected and analyzed for this multiple case study. Four representative groups were chosen and interviewed after submitting their final reports for in-depth understanding of their inquiry process. The positive learning experiences found in the process of their inquiry into children's science ideas were as follows: (1) exploring children's ideas have brought the opportunity for enhancing pre-service teachers' science content knowledge. (2) the pre-service teachers developed their ability in creating questions that probe into children's understanding. (3) the pre-service teachers recognized that children have various incomplete and unstable science ideas. (4) the pre-service teachers could suggest teaching strategy based on their findings.

Child and youth welfare law in Korea is vague and complex. In a narrow sense it means the research on the provisions of the Child Welfare Act. In a broad sense it embraces all of the social welfare system regarding to the protection for children and youth. Regardless of the scope of child and youth welfare law it should be cleared what the term of child and youth means in Korean legal regulation. Historically, child protection in Korea was based on the good intentions of individuals to protect war orphan children from poverty or danger after the end of the Korean War. It is the story of the evolving status of children from being viewed as dependant of the parents to becoming rights-based citizens, even not in Constitution. In Korea neither parents nor children have constitutionally recognized right. According to Korean Constitution the parents have only the obligation to educate their children. And the state ist obliged to improve the welfare of the youth(section 34). In compliance with this article there are lots of statutes regulating youth welfare. This article reviews the legal definition of child and youth to test the uncertain definition of child and youth welfare in relation to the treatment of children's and youth's legal status in Korea. According to the Child Welfare Act child is the person under age of 18, while the legal definition of youth oscillates between the person under the age of 19 and the person over the age 9 to the age of 23. As a result child welfare is often used as the synonym of youth welfare, and vice versa. The lack of the arrangement of the legal definition of child and youth is based on the historical reasons that the legal definitions of youth (under the age of 19 or over the age 9 to the age of 23) newly appeared in the statutes regulating youth welfare, whereas the Child Welfare Act still maintained the definition of child under the age of 18. In order to get rid of the confusion of the definition of the child and youth, a part of certain statues should combine with another Act according to the purpose of the individual amended statutes. And the definition of child and youth should be subdivided into 3 or 4 classes, namely infant(0-6), child(7-13), youth(14-18) and young adult(19-26). Furthermore this article proposes a reform of the existing legal system pursuant to the nature of the law, i.g. whether the issued or amended Act takes on a selective(residual) or universal character.

The concepts of ratio and proportion do not develop in isolation. Rather, they are part of the individual's multiplicative conceptual field, which includes other concepts such as multiplication, division, and rational numbers. The current study attempted to clarify the beginning of this development process. One fourth student, Kyungsu, was encourage to schematize his trial-and-error-based method, which was effective in solving so-called missing-value tasks. This study describes several advancements Kyungsu made during the teaching experiment and analyzes the challenges Kyungsu faced in attempting to schematize his method. Finally, the mathematical knowledge Kyungsu needed to further develop his ratio and proportion concepts is identified. The findings provide additional support for the view that the development of ratio and proportion concepts is embedded within the development of the multiplicative conceptual field.

The purposes of this study were to survey the elementary students' conceptions of electric circuits and of electric currents, and to explore the relationships between them. The questionaire were developed into matched forms which corresponds to each conceptions of electric circuits and electric currents. The elementary students were selected from 4th and 5th grade in a elementary school in a large local city, which of the total numbers of students were 163. The student who have well-developed conception in electric circuits are superior in conceptions of electric currents to other student who have not in each items of questionnaire required to draw a simple basic electric circuits for lightening the bulb, to select the basic elements of circuits, to identify the arrangement of batteries and bulbs. So we concluded that the scientific conceptions of electric circuits could contribute to the scientific conceptions of electric currents, as expected in elementary science textbooks.

인지 어휘 유형(cognitive dictionary)이란 단어 연상의 반응 어휘를 인지 유형에 따라 분류, 분석하는 것을 가리킨다. 인지 어휘 유형 개념을 McNeill의 언어 발달 연구에 준하여 논의하였다. 즉 아동의 어의(語義) 발달은 자작문(自作文) 형식(形式) 표현에서 시작되어 어휘 사용에 이른다는 것이다. 한편 Moran은 범세계적으로 유아들의 인지 어휘 유형은 단어의 동작적(動作的) 특성에 주로 의거한다는 것을 발견했는데 이는 언어의 효시에 관한 Piaget 나 Bruner의 이론과 일치하는 것이다. Moran의 인지 어휘 유형의 추가 개념은 Bruner의 심상(心象)(ikonic representation)에 의한 관계, 기능적 관계 (functional representation), 논리적(logical)관계를 포함한 단어의 연합 관계에 반영시켰다.

The purpose of the study was to investigate the effects of the use of RNP curriculum based on Lesh translation model on third grade students' understandings of fraction concepts and problem solving ability. Students' conceptual understandings of fractions and problem solving ability were improved by the use of the curriculum. Various manipulative experiences and translation processes between and among representations facilitated students' conceptual understandings of fractions and contributed to the development of problem solving strategies. Expecially, in problem situations including fraction ordering which was not covered during the study, mental images of fractions constructed by the experiences with manipulatives played a central role as a problem solving strategy.

Many misconceptions regarding biology and evolution have been reported by students prior to being exposed to a formal education program of evolution which challenged them. This study sought to investigate and to analyze the misconception formation process of evolution originating from TV animation and science books for children. Firstly, to identify TV animation's influence on students' misconceptions of evolution, a questionnaire including TV animation characters was constructed and administered to 146 elementary school students, 161 middle school students, and 156 high school students. The data collected was analyzed. Secondly, 17 science books for children were sampled and the contents related to evolution were selected and analyzed in terms of five evolutionary explanations: creationism internal will explanation, teleological explanations, explanations of use and disuse, mutation and finally, natural selection. Children have understood 'growth' and 'metamorphosis' on TV animation as 'evolution'. The processes by which characters on TV animation undergo some forms of change, which are in fact a kind of metamorphosis has often been understood as 'evolution'. Many respondents have defined evolution incorrectly as the process of growing and changing shape. On the other hand, some science books fur children contained descriptions of evolution including' mutation and finally natural selection explanation'; however, most of the science books fur children sampled in this study were written through the perspectives of alternative evolutionary views such as 'teleology view', 'internal will view', and 'use and disuse view'. It is apparent that TV animation and science books fur children influence the formation of various misconceptions regarding evolution by children.

A fraction is one of the most important concepts that students have to learn in elementary school. But it is a challenge for students to understand fraction concept because of its conceptual complexity. The focus of fraction learning is understanding the concept. Then the problem is how we can facilitate the conceptual understanding and estimate it. In this study, Moore's concept understanding scheme(concept definition, concept image, concept usage) was adopted as an theoretical framework to investigate students' fraction understanding. The questions of this study were a) what concept image do students have\ulcorner b) How well do students solve fraction problems\ulcorner c) How do students use fraction concept to generate fraction word problem\ulcorner By analyzing the data gathered from three elementary school, several conclusion was drawn. 1) The students' concept image of fraction is restricted to part-whole sub-construct. So is students' fraction understanding. 2) Students can solve part-whole fraction problems well but others less. This also imply that students' fraction understanding is partial. 3) Half of the subject(N=98) cannot pose problems that involve fraction and fraction operation. And some succeeded applied the concept mistakenly. To understand fraction, various fraction subconstructs have to be integrated as whole one. To facilitate this integration, fraction program should focus on unit, partitioning and quantity. This may be achieved by following activities: * Building on informal knowledge of fraction * Focusing on meaning other than symbol * Various partitioning activities * Facing various representation * Emphasizing quantitative aspects of fraction * Understanding the meanings of fraction operation Through these activities, teacher must help students construct various faction concept image and apply it to meaningful situation. Especially, to help students to construct various concept image and to use fraction meaningfully to pose problems, much time should be spent to problem posing using fraction.
