This study was conducted to evaluate the nutritional status of elementary school lunch programs. The subjects of this study consisted of 170 elementary school students(male 51.8% : female 48.2%) in the 5th and 6th grades. The dietary intake of nutrients was assessed by the modified 24-hour recall method. The results are summarized as follows: the average body weight was 41.3$\pm$7.93kg for boys and 40.5$\pm$ 8.35kg for girls. The average height was 149.5$\pm$5.88cm for boys and 146.2$\pm$5.82cm for girls. The total daily energy and nutrient intake was below the RDA's except for the intake of niacin and ascorbic acid. School lunchs provided 31.5% of total energy intake ; 32.5% of carbohydrate intake, 31.9% of protein intake and 33.4% of fat intake. Therefore, school lunchs largely contributed to the nutritional balance of these children. The food habit score was poor for 40.6% of the subjects.

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.

Purpose: The purpose of this study was to investigate the prevalence fate of obesity and to assess the relationship between obese children and their family Characteristics in 3 rural area in the Chung Cheong Nam Do province. Method: The children's height, weight and family characteristics of 327 5th and 6th grade elementary school students were obtained from the individual health records and self-recorded questionnaire surveys from June 25th to July 15, 2004. Results: The results of this study are summarized as follows: 1. The prevalence rate of obesity of 5th and 6th grade of rural elementary school students was 10.5%. 2. 20.9% of obese children had obese family members and 9.4% of obese children did not have any obese family members. The birth order, family size and family structure showed no significantly difference. 3. The obese children were more affected by their parents' concerns of body image (upper quartile of 84.1) and exercise (upper quartile 61.4%) than normal children. However, there was no significantly increase with the parents' concerns about meals. 4. There was no relationship in the obese children by PBI. 5. There was no relationship in the obese children by FACES III. Conclusion: The elevation of a parent's concern of their obese child about meal regulation should be investigated further.

본 연구의 목적은 자녀의 초등학교 입학이 취업모의 근로조건을 어떻게 변화시키는지 살펴보는 것이었다. 분석을 위해 육아정책연구소에서 실시하는 한국아동패널 4-8차년도 자료를 활용하였다. 구체적으로 본 연구에서는 자녀의 초등학교 입학이 어머니의 임금, 근로시간, 상용직 취업확률에 미치는 영향을 살펴보고자 하였다. 분석 결과의 내생성(endogeneity)를 통제하기 위해 균형패널 데이터를 대상으로 회귀불연속설계를 사용하여 분석한 결과와 불균형패널 데이터를 대상으로 Heckman 선택모형을 사용하여 분석한 결과를 비교하여 제시하였다. 분석결과 자녀의 초등학교 입학은 어머니의 임금수준, 근로시간, 상용직 취업확률에 부정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 자녀의 초등학교 입학이 단순히 여성의 경력단절 문제뿐만 아니라 양질의 일자리에 진입하는 것을 어렵게 만들 수 있다는 것을 보여준다.

This study investigated the relationship of children´s perceived competences and the home environment stimulation. The subjects of this study were 120 boys and girls enrolled in grade 3 and their mothers from three elementary schools. Instruments included the inventory of home stimulation(HOME) for elementary school children and the perceived competence scale for children. The main results obtained from this study were as follows; The degree of children´s perceived competence differed according to children´s sex, birth order, mother´s education, father´s education, mother´s employment satisfaction, income of the family, type of the family. And the children´s perceived competence and the home environment stimulation were a positive correlation.
