This research aims to present the ego-centered topic citation analysis, which is a new application of White's ego-centered citation analysis, for analyzing multilayered knowledge structure of a subject domain. An experimental topic citation analysis was carried out on the folksonomy research documents retrieved from Web of Science. Ego-centered topic citation analyses on folksonomy research domain were conducted in three stages: ego-documents set analysis, topic citation identity analysis, and topic citation image analysis. The results showed that the ego-centered topic citation analysis suggested in this study was successfully performed to illustrate the inner and the outer knowledge structures of folksonomy research domain.

The purpose of this study was to examine the effect of theme centered block play on young children's metacognition and sociality. The subjects of this research were a total of 60 five year old children from two classes in Gwangju. The average age of the subjects was 73 months. The subjects were randomly assigned to two groups. The experimental group participated in theme centered block play activities while the control group participated in free block activities. The collected data were analyzed by t-test using the SPSS program. The results of this study were as follows: The experimental group showed significantly higher improvement than the control group in young children's metacognition and sociality. Therefor, it might be concluded that theme centered block play activities contributed to the development of metacognition and sociality of young children.

The construction of ontology defines as complicated semantic relations needs precise and expert skills. For the well defined ontology in real applications, plenty of information of instances for ontology classes is very critical. In this study, crawling algorithm which extracts the fittest topic from the Web overflowing over by a great number of documents has been focused and developed. Proposed crawling algorithm made a progress to gather documents at high speed by extracting topic-specific Link using URL patterns. And topic fitness of Link block text has been represented by fuzzy sets which will improve a precision of the focused crawler.

Since sentences are the basic propositional units of text, their themes would be helpful for various tasks that require knowledge about the semantic content of text. Despite the importance of determining the theme of a sentence, however, few studies have investigated the problem of automatically assigning the theme to a sentence. Therefore, we propose a sentence theme allocation scheme based on the head-driven patterns of sentences in encyclopedia. In a serious of experiments using Dusan Dong-A encyclopedia, the proposed method outperformed the baseline of the theme allocation performance. The head-driven pattern 4, which is reconfigured based on the predicate, showed superior performance in the theme allocation with the average F-score of $98.96\%$ for the training data, and $88.57\%$ for the test data.

The Information-Oriented Society that we live in today has given lots of conveniences whereas it has serve problems and even is becoming social problems. These problems can have much worse influence to the little children who are immature. This research developed the new teaching-learning programs that can improve the learner's information communication ethical with theme-based integrated learning by analyzing present information communication curriculums. In addition, we apply the teaching-learning programs to the elementary school and analyzed the effects. As the result of this study, It is appeared that theme-based integrated learning for information communication ethical education gives good effects on information communication ethics improvement.

Today's society demands that Individuals need to acquire skills to select information they need, read critically that have been gathered and use them for their advantage. The ability to actively respond to information can be cultivated through reading which facilitates creative, critical thinking, and self-initiated learning. This research presents results from a study in which subject-centered approach to reading guidance was applied to elicit positive changes in reading attitudes and to contribute to the elevation of self-concept among adolescents. Using survey questionnaire, we compared the changes in reading attitude before and after treatment. The results indicate that subject-centered reading instruction brought positive changes in reading attitude among middle school students, contributed positively to the formation of self-concept and the improved student initiated learning.

This study aims to analyse the necessity of the subject heading construction for the word based classification and to suggest a methodology that uses various knowledge organization systems(KOS). For this purpose, six kinds of KOS were collected for the 20 selected works in each subject. The collected subjects were analysed in terms of constructing a subject heading for the word based classification. The result of the analysis shows that there is a noticeable difference between the library oriented KOS and commercial oriented KOS. In addition, user oriented tags are more similar to the commercial sector's concerning subject categorization than the library oriented ones. However, there is no noticeable difference among the library oriented KOS, commercial sector oriented KOS, and user oriented tags regarding the subject vocabulary. Some practical implications were suggested for the application to the Korean libraries based on the findings of this study.

For this study, we reviewed theoretical background of STEAM education and domestic and international studies in STEAM education, by doing so, we developed and applied the STEAM education program based on topic-specific project. This program is designed for the 3rd and 4th lesson of 6th graders' science in elementary school. As a result, the positive attitude about science of the students who went through the researched program increased with meaningful difference compared to that of the sample population. The result of this study shows that the STEAM education program based on topic-specific project can brings positive changes for the science-related affective domains.
