Cardiomyopathy (CMP) is a heterogeneous disease caused by a functional abnormality of the cardiac muscle. CMP is of 2 major types, dilated and hypertrophic, and is further classified as either primary or secondary. Secondary CMP is caused by extrinsic factors, including infection, ischemia, hypertension, and metabolic disorders. Primary CMP is diagnosed when the extrinsic factors of secondary CMP are absent. Furthermore, the World Health Organization, American Heart Association, and European Cardiology Association have different systems for clinically classifying primary CMP. Primary CMP is rare and associated with a family history of the disease, implying that genetic factors might affect its incidence. In addition, the incidence of CMP varies widely according to patient ethnicity. Genetic testing plays an important role in the care of patients with CMP and their families because it confirms diagnosis, determines the appropriate care for the patient, and possibly affects patient prognosis. The diagnosis and genetic identification of CMP in patients' families allow the possibility to identify novel genes that may lead to new treatments. This review focuses on the epidemiology, pathophysiology, diagnosis, and treatment of CMP, with the aim of providing pediatricians with insights that may be helpful in the early identification and management of idiopathic CMP in children.

Purpose: The purpose of this study was to develop a MOL instrument for school-age children in grades 4 through 6. Method: The research design was a methodological study. A four-phase design involved. 1) Interview data generated from professors, nurses, and elementary school students (n=8). 2) Content validation by expert panel (n=14) 3) Initial items corrected by elementary school students (n=20) 4) Instrument validation by survey (n=574). Finally, 24 items were chosen as a meaning of life scale for late school-age children. Results: The Cronbach's alpha coefficient of 24 items was .893 indicated a high internal consistency of the instrument, 2) Through factor analysis, 5 factors were extracted. These factors were labeled as 'relational experience', 'positive attitude', 'satisfaction/ hope', 'pursuit of goal', and experience of family love. These factors explained 52.311% of the total variance. Conclusion: The MOL scale for late school-age children can be used in nursing programs to improve the meaning of life. Studies on difference in meaning of life for late school-age children are needed for reverification.

Purpose: This study is an examination of the paths in which the primary factors of anxiety, impulsiveness, knowledge of life safety practice, attitudes towards life safety practice, interpersonal support, and self-efficacy from Pender's Health Promotion Model influence the practice of life safety behavior in school-age children. Methods: The sample consisted of 489 5th and 6th grade students recruited from five elementary schools in Seoul City and four provinces, South Korea. Data were analyzed using descriptive statistics, correlations, factor analysis, and structural equation modeling. Results: Attitudes towards life safety practice, interpersonal support, self-efficacy and impulsiveness directly influenced practice of life safety behavior. Anxiety did not have a direct influence on practice of life safety behavior, but indirectly affected it. In this modified model, 52.0% of the practice of life safety behavior was explained by the primary factors. Conclusion: To facilitate the practice life safety behaviors in late childhood, a positive attitude towards life safety needs to be developed along with decreasing impulsiveness and enhancing self-efficacy.

Sex does not mean simply the physical behaviors related to man and woman, rather the sexuality needed socializing process toward total personality. It is believed that religion or social norms on sex, limit talking about sex openly. But children have, their own sexual thinking and want to know why and how. This survey was conducted to find out the need in sex education of primary school students and their parents in Seoul area, comparing students'sexual knowledge, attitude, and behavior to their parents', in October 1989. Total 400 students and their parents who are attending two primary school in Seoul, were given the questionnaires, and 395 students' and 310 parents', respectively, were finally analyzed. The following results were obtained. 1. The mean of 11 questions In asking sexual knowledge of students was 6.18, and showed no difference between boys and girls. But the higher grade, the higher score. 2. The positive attitudes on marriage and sex roles were showed, but negative on physical changes with puberty, which was same to the parents' reaction. 3. Moro than three-forths of students wanted to take sex education class, and one-third of them believed that it should be conducted by school nurses. This was accorded with their parents. 4. The sexual knowledge degree and attitudes of parents went proportionately to their higher educational background. Protestants reacted more negatively to the given sexual terms. No significant difference was made among the age groups of them. As stated above. the degree of sexual knowledge and attitudes are movable accordingly to their children's sexual thinking and need. Therefore, it is strongly recommended that sex education In the primary schools should be conducted systematically involving parents, especially mothers. And it is suggested that school nurses undertake their responsibilities as the sex educators.

In this paper, firstly examined various proofs types that cover informal empirical justifications by Balacheff, Miyazaki, and Harel ＆ Sowder and Tall. Using these theoretical frameworks, justification activities by 5th graders were analyzed and several conclusions were drawn as follow: 1) Children in 5th grade could justify using various proofs types and method ranged from external proofs schemes by Harel & Sowder to thought experiment by Balacheff This implies that children in elementary school can justify various mathematical statements of ideas for themselves. To improve children's proving abilities, rich experience for justifying should be provided. 2) Activities that make conjectures from cases then justify should be given to students in order to develop a sense of necessity of formal proof. 3) Children have to understand the meaning and usage of mathematical symbol to advance to formal deductive proofs. 4) New theoretical framework is needed to be established to provide a framework for research on elementary school children's justification activities. Research on proof mainly focused on the type of proof in terms of reasoning and activities involved. But proof types are also influenced by the tasks given. In elementary school, tasks that require physical activities or examples are provided. To develop students'various proof types, tasks that require various justification methods should be provided. 5) Children's justification type were influenced not only by development level but also by the concept they had. 6) Justification activities provide useful situation that assess students'mathematical understanding. 7) Teachers understanding toward role of proof(verification, explanation, communication, discovery, systematization) should be the starting point of proof activities.

Objectives : The purpose of this study was to examine the factors related to children's health behavior. Methods : A self-administered questionnaire survey was carried out for 431 (boys; 227, girls; 204) children, 6th grade students, in Taegu from December 14 to 18 in 1998. This study employed health promotion model as a hypothetical model. Collected data were analysed through the chi-square test, ANOVA, and path analysis. Results : By univariate analysis, in case of boys, health practice was related to perceived self efficacy, perceived health status, perceived benefits of health-promoting behaviors, and perceived barriers, and in girls, health practice was related to perceived self efficacy, perceived benefits of health-promoting behaviors, perceived barriers, and cues to action. By path analysis, in case of boys, the better economic status, the younger mothers' age, the higher score of family cohesion and adaptability, healthier, the more perceived benefits, and the less perceived barriers were, the more health behaviors were practiced. Girls did the more health practice, in case of living with parents only, the higher score of family cohesion and adaptability, the more perceived self-efficacy, the less perceived barriers, and the more cues to action. Family cohesion had the most important effect on health practice of primary school students. Conclusions : In order to promote health behavior of primary school students, a good family environment as well as health education might be very important. That is, we have to try together in home and as well as in school.

This students ideas in science are diverse and unique It is realized that children's preconceptions and misconceptions established before lessoning hgve a crucial in fluence on the following education. so it is meaningful to analyse the children's concept of temperature for the better teaching strategy in this study. This survey of the Elementary school children's concept is designed for the subtopics of temperature as the relation between heat and temperature, He relation between volume(size) and temperature, the temperature of change of state on water, the temperature of substances in the condition of thermal equilibrium. Using Clinical method, this research was executed to 306 children at elementary school. The network method or the analyse of questionnaires were used to analyse the children's response. Findings of this survey are as follow. Students are already familiar with such concept as this increase of temperature by geating, but they think every substance is not the case. Many students appears to believe that the temperature of an object(substance) is related to its size(vloume) Qualitative tasks are difficult than qualitative ones. This trend appear highly in the low grade students. Don't know the temperature of change of state on water and it's stability They think that the temperature is determined by the heating time(period) and the temperature of heating source. Students think, in general that temperature of substance in the condition of thermal equilibrium is different.
