For the purpose of developing Milk-based nutritional education program, this study analyzed the awareness of milk and milk nutritional knowledge of elementary/middle/high school students and set appropriate instructional goals for milk nutritional education program. According to the analysis results, 49.6% of total subjects know a little about the milk, otherwise 42.3% of total subjects don't know it Elementary school students know better than other students. Therefore, the instructional goals of nutritional education program were set as follows, that improve the level of the awareness about milk, and to increase the understanding on the knowledge about milk, and to practice proper milk intake behavior. Based on these goals established as the above, educational contents were established that would be expected in elementary, middle, and high school students after milk nutritional education. Therefore, the development of education program and the evaluation of education effects were to be performed on the basis of educational goals and contents for milk nutritional education program.

Objective: The purpose of this study was to understand the needs of teachers in daycare centers for preschoolers in providing health education and health care services and to identify competencies and barriers to health education among the teachers. Method: A total of 410 teachers from 496 public daycare centers were recruited. Participating daycare centers were selected using a stratified sampling method. Data were collected from June to August 2002 using mailed questionnaires. Result: About 37% of the daycare centers provided health education more than 6 times during the past year and 92% provided annual health screenings. Traffic safety, personal hygiene, and sexuality education were most frequently provided. Regarding in-service education for daycare teachers, 62.7% had obtained health related education. Sexuality education, traffic accident, and injury prevention were the main topics for the in-service education. The teachers had relatively higher competencies and lower barriers to health education, while they also had proper knowledge related to health of children. Conclusion: Based on the study results, health professionals could plan and develop health promotion programs to meet the needs of teachers and children in daycare centers.

The purpose of this research is to explore teachers' role actions in teaching mathematical problem solving and to analyze the influences of the teachers'role actions on their students' activities and beliefs about problem solving. The results obtained in this study suggested that the teachers' role actions brought qualitative differences to students' activities, and students' beliefs about mathematical problem solving were consistent with the perspective held by their teachers. Therefore, teachers should help students build up desirable beliefs about problem solving. They should understand teaching mathematical problem solving and play proper roles in various situations of teaching mathematical problem solving.

This paper is discussing about the culture of mathematics classroom for problem solving. The mathematics classroom which we have to aim at is where every students make proper belief and attitude about mathematics, and also can express their own idea and make question freely. In that classroom, the students can meet with various problem solving methods and communicate with other students, and then elaborate their own method.

Classical mechanics begins with some variants of Newton's laws. Lagrangian mechanics describes motion of a mechanical system in the configuration space which is a differential manifold defined by holonomic constraints. For a conservative system, the equations of motion are derived from the Lagrangian function on Hamilton's variational principle as a system of the second order differential equations. Thus, for conservative systems, Newtonian mechanics is a particular case of Lagrangian mechanics.(omitted)

This study aimed to investigate how the current elementary school teachers think about nutrition education, how they are teaching, and what kind of problems have occurred. And this study was made to provide basic materials to be used for the effective nutrition education in the elementary school. The survey was done on 60 elementary school teachers and 570 elementary school students of the 5th and 6th grade in Gyeonggi Province by questionnaire and analyzed for the perception of nutrition education, current status of nutrition education, nutrition knowledge and cooking knowledge. The average scores of nutrition knowledge were 2.72 for male and 3.75 for female students out of full score of 5. The fifth grade students learned more nutrition education than the sixth grade ones in accordance with the different curricula. Nutrition education was taught as apart of other subjects(87%) and mainly done by lectures. For most of the students, information source of the nutrition education was the meal service(47.4%) and the most common one was the Internet that 38.1 % of the teachers used. Most of the students responded that nutrition education was necessary in the curriculum of elementary school for proper growth(36.2%), intelligence(25.9%), health(21.5%), and dieting(16.4%). The perception for the suitable teacher was in the order of nutrition specialist and dietician. And the right time of the related class was in the order of spare time everyday, a special activity time, and the meal service time. The important contents of nutrition education were in the order of proper eating habits, growth & nutrition, food hygiene and diseases. Nutrition problems of the elementary students were in the order of unbalanced diet, too much ingestion of processed and instant foods, lack of table manners, and child fatness and weakness. 80.0% of the teachers supported the early nutrition education and demanded it should begin when children are in kindergarten. The analysis showed that nutrition education should be taught by parents(29.4%), teachers(29.2%), and nutritionists(25.9%) and that family and school should cooperate closely. Main responses of the teachers to the children's problems were that they had too much instant food, did not eat in a variety, and had no manners in eating. Ironically, they thought malnutrition, fainting and growth stunt were not important nutrition related problems.
