The purposes of this study were to evaluate the level of PCK which middle school science teachers have on the concept of density and to analyze the characteristics of science teachers' content representation on the concept of density by their PCK level. For that purpose, 20 science teachers were selected and asked to answer the questionnaire on the eight aspects of CoRe. Results of this study indicated that the science teachers' PCK levels were low in general and evaluated as below average. The differences among the characteristics of science teachers' content representation by their PCK level were high in seven aspects of CoRe but the one aspect of the understanding of learner's preconception. These differences were analyzed and the patterns shown by the science teachers in eight aspects of CoRe were drawn in this study. It was also found that the characteristics drawn in eight aspects of content representation shown by the teachers whose PCK level was medium were close to those whose PCK level was low rather than high in most aspects of CoRe.

Methods: The participants were selected among applicants for low-income family financing provided by the government and included 115 infants and toddlers as well as their guardians. Demographic data, nutrition knowledge, dietary attitudes, and nutrition intakes were assessed using a self-administered questionnaire, biochemical examination, and 24 Hour-Recall method. Results: The score for guardians' nutrition knowledge was 12.97 points of a possible 15, and the score for dietary attitudes was 53.38 points of a possible 75. The nutrition knowledge and dietary attitudes showed significant differences by education level (p < 0.05) and family structure (p < 0.05). Energy intakes of subjects aged 6 ~ 24 months and over 25 months were lower than the DRI for Koreans. The intakes of carbohydrates, protein, and fat of subjects aged 6 ~ 24 months and over 25 months showed no significant differences by level of nutrition knowledge or dietary attitudes. The intake of Ca of subjects aged over 12 months showed significant differences by level of nutrition knowledge (p < 0.05). The intakes of Thiamin of subjects aged 6 ~ 11 months and P of subjects aged over 12 months showed significant differences by level of dietary attitudes (p < 0.05). There was a small positive correlation between education level and nutrition knowledge as well as between dietary attitudes. Nutrition knowledge showed a positive correlation with dietary attitudes. There was a positive correlation between nutrition knowledge and Ca, Riboflavin, as well as Vit C levels. Conclusion: Therefore, it is necessary to consider an educational program for increasing the practical application of knowledge to nutrition management for improvement of nutrition intake in infants and toddlers.

This study aimed to investigate the impact of arthritis self-management education on changes in arthritis-related knowledge levels and arthritis-specific self-efficacy among elderly individuals at a senior center. This study was conducted with one group pre-test and post-test design. The participants included 48 elderly individuals who utilized four senior centers, and they received arthritis self-management education for three weeks. Data analysis used a paired t-test to compare the effects before and after education. The results of the study showed that arthritis self-management education significantly increased arthritis-related knowledge (t=9.17, p<0.001) and arthritis-specific self-efficacy (t=3.96, p<0.001). There were significant differences in knowledge and self-efficacy levels by age group, with the results varying among participants aged 85 and above. These findings suggest that a three-week education program is appropriate for improving arthritis-related knowledge and self-efficacy among the elderly, and that education should be tailored to different age groups.

Recently, there has been a growing trend toward private brand. Although much has been written about the determinants of attitude and purchase intention on PB, little is known about the influence of manufacturer and retailer trust on private brand purchase. This research addresses three questions:(1) what impact do manufacturer and retailer trust have on private brand purchase?(2) What is a key mediating variable in the relationship retailer between trust(on retailer/manufacture) and purchase intention?(3) Are the impacts of these factors differ depending on the level of customer knowledge? The findings indicate that retailer trust directly influence on the perceived quality, attitude toward private brand, and purchase intention. Manufacturer trust affects on attitude and purchase intention, however, only when it is through perceived quality. In addition, the relative impact of theses two factors differs to some extent, depending on the level of consumer knowledge. When customer knowledge is relatively high, retailer trust is a very important factor influencing perceived quality, attitude and purchase intention. On the other hand, both retailer trust and manufacturer trust are considered when customer knowledge on private brand is low.
