Many former researchers demonstrated that algorithm learning has a positive outcome on students' problem-solving abilities. One of the methods for algorithm learning, the 'programming learning' method is highly effective. However, there are numerous constraints in schools for programming learning. This study attempts to overcome these issues. Squeak Etoys, one of the educational visual programming languages for easy and interesting learning, has been selected as a learning tool. We developed the algorithm-learning curriculum for middle school students. They were divided into a control group and an experimental group. The students learned on the basis of equal curriculum but, they used other learning tools through over a total 6 sessions. The result showed that Squeak Etoys based Algorithm learning has a positive effect on improving middle school learners' problem solving abilities, self-efficacies and logical thinking abilities. Although the students' logical thinking abilities in the experimental group are improved a lot more than the students' abilities in control group, the students' logical think abilities in the both groups are improved. Therefore, algorithm education in secondary schools are necessary. In conclusion, Squeak Etoys based Algorithm learning has a positive effect on problem solving ability and self efficacy. The developed curriculum can be applicable as a basis for study on algorithm learning and educational programming language.

The purpose of this study was to evaluate the effectiveness of vegetable-related nutrition education for fourth grade elementary school students in Gyeongnam province. A comparative analysis of nutritional knowledge on vegetables, vegetable preferences, and vegetable intake in school foodservices were assessed between a control group and an experimental group. The control and experimental group contained 62 and 67 students, respectively, and the experimental group received nutritional education in four sessions (40 minutes each session) per week. A self-administered survey was conducted before and after this education, and 122 questionnaires (for 61 members of the experimental group and 61 members of control group) were analyzed. In the experimental group, there was a significant (p<0.001) increase in vegetable-related nutrition knowledge (form 5.02 to 6.10 out of a total score of 9), while there were no significant differences in the control group. Vegetable preference scores also significantly (p<0.001) increased (from 3.44 to 3.85 on the 5-point Likert scale) in experimental group, while there were no significant difference in control group. We also observed a significant (p<0.001) increase in vegetable intake from school foodservices (89.34% to 95.49%) in the experimental group, but there were no significant differences in the control group. In conclusion, a vegetable-related nutrition education for fourth grade elementary school students was effective at improving the nutritional knowledge of vegetables, vegetable preferences, and vegetable intake from school foodservices. Therefore, to encourage the vegetable-related right dietary habits, sustainable, and systematic nutrition education programs should be implemented for elementary students.

It is important to practice preventive method to control oral disease. Dental caries tendency has been decreased in developed countries, but early childhood caries(ECC, BBTD) became serious dental problems in many countries. To slove these problems, more positive and definite prenatal programs on infants and child are needed. Mostly the control of oral health was affected by a mother's knowledge and behavior in this stage. According to many studies, prenatal education is the most effective method to promote oral health in children. But in Korea, there is little oral health education programs for pregnant women, nursing mothers, infants and children. The purpose of this study was to access the knowledge and opinions of caries prevention among gravid women. 330 pregnant women(primiparae=181, multiparae=149), aged 23 to 39 years were randomly selected at prenatal health education courses in Seoul, Korea, 2000. Face-to-Face interviews were conducted by a trained interviewer using questionnaires included demographics, attitude toward children's dental cares, knowledge of early childhood caries, knowledge concerning pregnancy and oral health. The obtained results were as follows; (1) Most respondents were very concerned about their children's oral health. (2) 58% of the respondents were unaware of early childhood caries and the proportion was significantly higher among primipara (p<0.05). (3) Only 43% of the respondents believed that improper breast feeding could develop ECC, the proportion was significantly higher among primipara(p<0.05). (4) 82% of the respondents reportedly believed that the fetus takes away calcium from the mother's teeth during pregnancy. (5) 71% of the respondents believed that dental treatment during pregnancy was unsafe. There is a relatively low level of accurate knowledge regarding infant nutritions, maternal need for oral health and dental caries prevention among pregnant women. Oral health education and promotion programs that are science-based are needed for gravid women.

Objectives: To survey the awareness of patient to scrub typhus to provide data for education and communication concerning scrub typhus. Methods: Patients with scrub typhus (case group, n=299) and people without scrub typhus within the previous 2 years (control group, n=598) were matched for age (within 5 years), gender, and occupation (farmer or non-farmer). The participants were recruited from 15 study areas between October and December 2006. Results: The awareness rate of scrub typhus was 75.1%, and was significantly higher than in the case group (79.4% vs. 66.6%, respectively; p<0.01). The major routes of awareness were from 'past history of scrub typhus in family members or neighbors' (54.9%), 'television' (28.3%), and their past history of scrub typhus (5.5%). The average correct rate of scrub typhus was 48.4%, and the correct response rate of cases was significantly higher than controls (p<0.01). Especially, the correct rate of etiology, incubation period, route of transmission, and acquired immunity was <40%. Through conditional logistic regression test, the factor significantly associated with awareness in case group was age (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.94-0.98). And the factors associated with awareness in control group were female (OR, 1.56; 95% CI, 1.03-2.36) age (OR, 0.98; 95% CI, 0.96-0.99), family history of scrub typhus (OR, 10.18; 95% CI, 1.37-75.99), history of receiving prevention education (OR, 8.47; 95% CI, 1.14-63.00). Conclusions: The rate of awareness was relatively low in study population. Thus, effective working guidelines and educational program to prevent scrub typhus must be developed, and publicity activities about the prevention of scrub typhus are needed for high-risk groups.
