The basic purpose of 2007 revision curriculum is content of activity oriented, management of differentiated instruction, communication, introduction of story mathematics, mathematical exploration and problem solving ability and so on. In this paper, we investigate some characteristics of number teaching in the primary school of New Zealand. Especially, focused on materials and methods and so on. So we've got the following results. First, there are no fundamental differences in materials and methods in teaching number between Korea and New Zealand but in New Zealand there are no national textbook like us so there is a possibility not to teach number systematically like our Korea. On the contrary, they divide number region from one to six level and are offering achievement objects, suggestive learning experiences, sample assessment activities for each level and also they do not guide activities itself in detail like us and so have learners themselves think about the given problems. Second, there is a strategy stage in getting knowledge about number in New Zealand and so children can take advantage of this steps according to the type of problems. Third, it must be developed some materials and idea to reach the learning purpose rousing interest of children.

This study is to develop assessment framework, test items and questionnaire for the National Assessment of Educational Achievement(NAEA), which administered in the elementary and secondary schools across the country in this year(2000). According to the first year study result of the NAEA, the test was administered in two core subjects, Mathematics and Social Studies. In this study, test items and sets of questionnaire and administered pretest were developed in the last year. In this year, the NAEA was administered with the adjusted test items and questionnaires and the results was analyzed and would be reported to the public. NAEA was developed on the basis of national curriculum, especially of the nature and objectives of subject curriculum in Mathematics (and also Social Studies). In the framework of assessment, we set up four differentiated levels of student achievement:‘under basic’,‘basic’,‘intermediary’, and ‘advanced’. Here ‘the intermediary level’means the level of educational achievement in which students can understand average content of subject curriculum. ‘Advanced level ’indicates the level of educational achievement in which students master all the content of subject curriculum and apply basic concepts and principles to a variety of situations. ‘The basic level’means the level of educational achievement in which students do not achieve the intermediary level. Students who do not understand average content of subject curriculum are classified as belonging to the basic level. Finally, this study would explain how to administer and analyze the test int he future. The test result was analyzed to report students’s educational achievement according to regions, content area, behavioral characteristics, and etc. This study would show how to report test results and how to set up student’s academic achievement.

Purpose: The purpose of this study was to investigate the influencing factors on externalized and internalized problem behaviors among high school students. Methods: The subjects for this study were 707 students in two high schools in K province. The data were collected during the period from October to November, 2014 by use of questionnaires. The instruments used were the Korean Youth Self-report, Daily Hassles Questionnaire, State-Trait Anger Expression Inventory, and Ego Resiliency Scale. The data were analyzed using SPSS. Results: Significant predictors to explain externalized problem behaviors comprised anger-out, anger-in, anger-control, relation with parents, daily stress, and religion. It was found that these factors explained 46% of externalized problem behavior. Ego resiliency, anger-in, daily stress, gender, relation with parent, and anger-out were significant predictors to explain internalized problem behaviors. It was found that these factors explained 45% of internalized problem behaviors. Conclusion: This study suggests that the influencing factors on problem behaviors differ from externalized and internalized problem behaviors. So these findings will provide the basic data to develop a program that is differentiated by problem behavior type.

Previous studies showed that many secondary school students and teachers have difficulties in distinguishing the phenomena of dissolution and diffusion, as well as the phenomena of diffusion and effusion. In this study, currently accepted term definitions of dissolution, diffusion and effusion were searched from the IUPAC Gold Book and the physical chemistry textbooks, and the points to differentiate the definitions were sought. Also, the term definitions of these three phenomena in the secondary school text books and the college general chemistry textbooks were surveyed and compared to the currently accepted definitions. It was found that dissolution is formation of one new phase from mixing two phases, while diffusion is the migration of matter down from the concentration gradient. The "concentration gradient" is considered to be a key point to distinguish diffusion from the dissolution. However, the concentration gradient was not mentioned in the definitions of diffusion in most of the secondary school textbooks and the college general chemistry textbooks. Effusion is differentiated from diffusion by the gas molecules escaping from the container through a tiny hole without collision. The definition of effusion was not found in most of the secondary school textbooks.

This study examined the experience of administrators of home-based child care centers about CCFSM (Center for Children's Foodservice Management) service using a qualitative approach. Eight administrators of home-based child care centers in Seoul with more than one year's experience of CCFSM were interviewed regarding their opinions on support activities, standards, and foodservice management. The interviews were semi-structured with open-ended questions and they were transcribed and classified according to the subjects. There were negative opinions regarding the indications after a hygiene inspection leaving photographs or records behind, but most positive opinions were about round visits for foodservice sanitation and nutrition management. The participants thought that it is not enough that the number of nutrition education sessions for children be twice a year, and there was a suggestion to increase the rentals of nutrition educational materials. There was a complaint about the menus in that were difficult to prepare for lunch time or to obtain food ingredients for. The administrators poorly recognized how to use the standardized recipes and chlorine-based disinfectants, so they could not be applied properly. They also pointed out the problems of joint purchasing as low quality and high prices in the food service operation. They felt discriminated against compared to with larger scale child care centers because of their size and expressed concerns regarding the fact that many home-based child care centers were not included due to the lack of publicity and budget. Through the results, the CCFSM should provide a differentiated service and management by creating a dedicated team or staff for home-based child care centers so they will not feel left out. In addition, It is also important to constantly gather opinions to improve the menus and to use standardized recipes practically. In addition, it will be necessary to develop nutrition educational materials corresponding to the infants' age for home-based child care centers and increase the rent to expand nutrition education.

The purpose of this study is to analyze comparatively adult literacy surveys of UK, France and Germany who have developed their own adult literacy survey tools independently. The results of the study show that these three countries are similar in that all of them utilize literacy survey tools linked to their own adult literacy policies. The survey tools of the countries are based on the definition of adult literacy as functional literacy and everyday life skill. The criteria of adult literacy levels are differentiated in the context of the countries. And SQC model is adopted as the main model of developing the survey tools. Through this analysis, the following implications could be obtained to improve Korean adult literacy survey. It needs 1) to unify execution subjects of adult literacy survey and adult literacy policy. 2) to develop survey tools reflecting everyday life, 3) to make tools into module form, 4) to pursue the efficiency of cost and utilization of tools.

Background: Smoking in adolescence leads to an intensified addiction to nicotine when physical and mental growth has not yet been completed. With the advent of e-cigarettes, the rate of e-cigarette use among Korean adolescents has been steadily increasing. To date, studies on e-cigarettes and oral health, especially on the relationship between smoking styles and oral health in adolescents, are limited. Therefore, this study aimed to identify the risk factors for oral health problems caused by the repeated use of conventional cigarettes and e-cigarettes. Methods: This explanatory research study compared the adolescents' experiences of periodontal disease symptoms according to smoking type through a secondary analysis of the original data from the 15th Adolescent Health Behavior Survey (2019). Cross-analysis was performed to compare the smoking patterns according to the adolescents' general characteristics. Finally, a binary logistic regression analysis was performed to determine how smoking characteristics affect the adolescents' experience of periodontal disease symptoms. Results: In terms of patients' general characteristics, significant differences were observed in sex, school level, grades, household economic status, type of residence, and father's education level between adolescents who smoked conventional cigarettes alone and those who smoked both conventional cigarettes and e-cigarettes (p<0.05). After checking the factors affecting the smoking pattern and the experience of periodontal disease symptoms in adolescents, it was found that the duplicate smoking group was more likely to experience periodontal disease symptoms (odds ratio, 1.20) than the group that smoked conventional cigarettes alone (p<0.05). Conclusion: Duplicate smokers experienced more symptoms of periodontal disease than those who smoked cigarettes alone. Based on the findings of this study, smoking cessation counseling according to the smoking type and differentiated education for oral health promotion should be provided.

BACKGROUND/OBJECTIVES: Unregulated inflammatory responses caused by hyperglycemia may induce diabetes complications. Hesperetin, a bioflavonoid, is a glycoside in citrus fruits and is known to have antioxidant and anticarcinogenic properties. However, the effect of inflammation on the diabetic environment has not been reported to date. In this study, we investigated the effect of hesperetin on proinflammatory cytokine secretion and its underlying mechanistic regulation in THP-1 macrophages with co-treatment LPS and hyperglycemic conditions. MATERIALS/METHODS: THP-1 cells differentiated by PMA (1 µM) were cultured for 48 h in the presence or absence of hesperetin under normoglycemic (5.5 mM/L glucose) or hyperglycemic (25 mM/L glucose) conditions and then treated with LPS (100 ng/mL) for 6 h before harvesting. Inflammation-related proteins and mRNA levels were evaluated by enzyme-linked immunosorbent assay, western blot, and quantitative polymerase chain reaction analyses. RESULTS: Hesperetin (0-100 µM, 48 h) treatment did not affect cell viability. The tumor necrosis factor-α and interleukin-6 levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions, and these increases were decreased by hesperetin treatment. The TLR2/4 and MyD88 activity levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions; however, hesperetin treatment inhibited the TLR2/4 and MyD88 activity increases. In addition, nuclear factor-κB (NF-κB) and Acetyl-NF-κB levels increased in response to treatment with LPS under hyperglycemic conditions compared to normoglycemic conditions, but those levels were decreased when treated with hesperetin. SIRT3 and SIRT6 expressions were increased by hesperetin treatment. CONCLUSIONS: Our results suggest that hesperetin may be a potential agent for suppressing inflammation in diabetes.
