  • In this study, we tried to devise a method to activate meta-affect in the aspect of supporting mathematics teaching and learning according to the need to find specific strategies and teaching and learning methods to activate learners' meta-affect in mathematics subjects, which are highly influenced by psychological factors. To this end, the definitional and conceptual elements of meta-affect which are the basis of this study, were identified from previous studies. Reflecting these factors, a teaching and learning model that activates meta-affect was devised, and a meta-affect activation strategy applied in the model was constructed. The mathematics teaching and learning model that activates meta-affect developed in this study was refined by verifying its suitability and convenience in the field through expert advice and application of actual mathematics classes. The developed model is meaningful in that it proposed a variety of practical teaching and learning methods that activate the meta-affect of learners in a mathematical learning situation.

  • The purpose of this study is to investigate how and which meta tags are used, which meta tags are used frequently, and what relationships there are between retrieval of WWW documents and meta tags. For the study, 1,000 WWW documents were selected and examined from OCLC NetFirst. The total of 92 meta tags was discovered and "description" and "keywords"meta tags were analyzed intensively. In addition, analysis of WWW documents showed that there are no significant relationships in meta tag usages between documents retrieved at the beginning and documents retrieved at the end. Comparative study between general internet search engines and commercial DBs such as NetFirst is suggested as a further study.

  • Objective : The purpose of this study is to work on the problems and on the direction of the study regarding the evidence-based study of Acupuncture. Methods : We reviewed the PubMed electronic database. Eight articles of systematic review without meta-analysis and six articles without meta-analysis were selected. Results : In the study of eight articles of systematic review without meta-analysis, there were two articles on effectiveness of acupuncture and one on non-effectiveness of acupuncture. Four articles were about the changes according to the quality of randomized controlled trials. Also, one article was about the side-effect of acupuncture. In the study of six articles of systematic review with meta-analysis, there were two articles on Odds Ratio, two on Relative Risk, one on number-needed-to-treat, and two on 18 predefined methodological criteria. Conclusion : As the quality of RCTs was high, positive response decreased and as the quality of RCTs was low, positive response increased. For the study of evidence-based acupuncture, it is necessary that we conduct research on well-planned placebo acupuncture, large sample size, statistical method, method of searching and assessing literature and method of meta-analysis.

  • Meta-cognition is the knowledge and cognition of cognitive phenomena, including the control of ones own memory, comprehension, and thought processes. Meta-cognition is similar to self-awareness, which is the understanding of oneself, and affects people's attitudes and behaviors. This study demonstrated the mediating effect of meta-cognition between internal locus of control and self-efficacy. Internal locus of control refers to the steady faith that any outcome is related to one's own efforts. Self-efficacy is a collection of personal strong belief that one individual can achieve his or her own goals. In this study, if a person has a tendency to adopt an internal locus of control, meta-cognition is improved, and self-efficacy can in turn be increased if meta-cognition is improved. This study conducted an empirical analysis through questionnaires conducted on 260 university students. The results of the research demonstrated that there is a highly positive correlation between meta-cognition, control position, and self-efficacy. In addition, this study emphasized that positive meta-cognition with internal locus of control can lead to positive attitudes and behaviors, and positive results.

  • Studies on meta-affect in problem solving tried to build similar structures among affective elements as the structure of cognition and meta-cognition. But it's still need to be more systematic as meta-cognition. This study defines meta-affect as the connection of cognitive elements and affective elements which always include at least one affective element. We logically categorized types of meta-affect in problem solving, and then observed and analyzed the real cases for each type of meta-affect based on the logical categories. We found the operating mechanism of meta-affect in mathematical problem solving. In particular, we found the characteristics of meta function which operates in the process of problem solving. Finally, this study contributes in efficient analysis of meta-affect in problem solving and educational implications of meta-affect in teaching and learning in problem solving.

  • Lately CBD methodologies like as CBD96, Catalysis, Fusion, and SCIPIO have been introduced. These methodologies has their own proprietary component reference model. Using proprietary reference model falls interoperability among methodologies. Furthermore it can cause confusion and difficulty for component developers, In this paper, we propose a integrated component meta-model for support consistency and interoperability among component designs. Also, we compare our proposed meta model to existing component reference model by using component's characteristics. We expect that it is easy to add new meta model elements and extends meta-model by using integrated component meta-model.

  • In this study, the researcher aimed to increase productive reflection of pre-service elementary teachers through meta-analysis of their own reflective journals. The meta-analysis activities are expected to enhance their learning effectively as a kind of self-assesment. During 8 week simulation teaching, 26 pre-service teachers kept individual journal writing and the meta-analysis activities were implemented twice (after the 3rd and 8th week). Right after the first meta-analysis, the pre-service teachers' productive reflection increased clearly. However this would not guarantee the effect would last long time period. By analyzing 8 week reflective journals, reports on meta-analysis activities and small group interview, this study shed light on practical ways of enhancing reflective teacher education.

  • The purposes of this study were to evaluate the adherence of bacteria on various denture base resin materials and effects of chitosan, added to denture base materials on bacterial adherence. PMMA denture base resin such as heat-cured Vertex-RS, self-cured Vertex-SC and 4-META denture base resin such as heat-cured Meta-Dent, self-cured Meta-Fast were used in this study Samples were divided into two groups the denture base resin with chitosan, without chitosan Streptococcus mutans and Lactobacillus casei were used in this study. The surface of samples was observed by SEM. When chitosan was added to M17 and MRS broth, viable cell count of bacteria was reduced. Viable cell count of Streptococcus mutans on the samples decreased as follows : Meta-Dent, Vertex-SC, Meta-Fast, Vertex-RS. Viable cell count of Lactobacillus casei on the samples decreased as follows: Vertex-RS, Meta-Dent, Meta-Fast, Vertex-SC. The resin with chitosan showed lower adherence of bacteria than without chitosan. The images of SEM showed that the surface of the resin with chitosan was rougher than that of without chitosan. These results showed that the denture base resin materials with chitosan have rougher surface than without chitosan, but less bacteria adhered on them.

  • This study introduces the construct of meta-parenting or a superordinate category of effortful cognition, including anticipation, assessment, reflection and problems. Also, it aims to analyse meta-parenting in terms of demographic variables and investigate how it relates to other cognitions on parenting and parenting behaviors. One hundred seventy three mothers of preschool children were surveyed on Hawk's (2007) Meta-Parenting, Sameroff and Feil's (1985) Concepts of Development, Stipek, Danniels, Galluzzo, & Milburn's (1992) Activities Sub-scales. They also commented on their views of appropriate methods of child-rearing and the starting age of extra-curricula activity and the number of extra-curricula activities. The main results were as follows: Mothers showed the highest score on assessment followed by anticipation, reflection and problems while these four components of meta-parenting were highly correlated to each other. Among demographic variables, only the mothers' age and education were linked to some component of meta-parenting. Meta-parenting was correlated with complexity of thinking but not with views on appropriate methods of child-rearing. Also, meta-parenting was associated with formal and informal activities at home and the beginning time of providing the extra-curricula activity with the total number of extra-curricula activities provided at present.
