The purpose of this study was to make an analysis of the conceptual diagrams of early childhood teachers about education for happiness in an effort to suggest the possibility and guidelines of this education. The subjects in this study were 100 teachers at kindergartens and daycare centers located in the city of Busan and South Gyeongsang Province. Out of them, 50 teachers each were selected from the kindergartens and the daycare centers. The conceptual diagrams drawn up by the early childhood teachers were analyzed to find out the numbers of superordinate concept, the number of content element, characteristics, hierarchy and density. The findings of the study were as follows: First, as for the content of education for happiness, superordinate concepts appeared 364 times in the conceptual diagrams of the kindergarten teachers, and there were 21 superordinate concepts overall in their diagrams. Second, concerning the content of education for happiness, superordinate concepts appeared 296 times in the conceptual diagrams of the daycare center teachers, and there were 18 superordinate concepts in total. The findings of the study showed that the kindergarten teachers had a better knowledge on the concept of education for happiness than the daycare center teachers, and that there was a difference between the two groups in what they considered valuable in relation to the content of education for happiness.

The citizen-initiative has been frequently mentioned in community building project which is being promoted by Seoul City. The citizen-initiative has become an important concept in the direction of community welfare efforts. However, this concept has not been defined clearly in social welfare. In this context, the purpose of this study is to find how the practitioners of the social welfare practice field recognize the concept of citizen-initiative. In this study, concept mapping method was used to generate 59 statements about the citizeninitiative in 10 social workers in Seoul. Multidimensional scaling analysis and hierarchical cluster analysis are used to do mapping and grouping the 59 statements. The results are as follows. A total of 6 categories were derived. The six categories are named "Inducement of Participation", "Practice", "Procedure", "Awareness and Interest extension", "Expression of Opinion", "Attitude and Emotion". "Practice" category was revealed as a core category in the concept of citizen-initiative. This study is meaningful as a first step to discuss "what is the citizen-initiative?" and to make consensus in social welfare academic area and practice field.

This study was conducted to investigate the relationship between physical self-concept, interpersonal relationship satisfaction, and sociality in 250 elementary school students participating in dance education activities. Using IBM SPSS 21.0 and IBM AMOS 21.0 programs, exploratory factor analysis, confirmatory factor analysis, reliability Analysis, correlation analysis and structural model analysis. First, physical self-concept has a statistically significant effect on interpersonal relationship satisfaction. Second, physical self-concept had a statistically significant statistical effect on sociality. Third, interpersonal relationship satisfaction showed a statistically significant effect on sociality. In conclusion, it shows that educating elementary school students to have desirable physical self-concepts can lead to interpersonal relationship satisfaction and formation of sociality.

The purpose of this study is to examine the pre-service teachers' concept of measurement uncertainty. The subject of this study were 27 pre-service middle-school teachers in Seoul. They carried out open-ended inquiry tasks and surveyed two kinds of open questionnaires, and interviewed several persons. We analysed their behavior and responses. Through the analysis, we summarize pre-service teachers' concept about measurement uncertainty with representation data, precision and accuracy, error analysis, propagation of uncertainty. The results show that the teachers' concept is different from scientists' concept. They make a mistake in using term of precision and accuracy and pay no attention to measure precisely. Also they only point out sources of error but don't consider how the error affects the results of experiment. The results of study will give! 1 some implications for the curriculum and teaching material developers in order that pre-service teacher and student gain scientific concept.

In real educational field, there are cases that concrete problematic situations are introduced after abstract concepts are taught on the contrary to process that abstract from concrete contexts. In other words, there are cases that abstract knowledge has to be concreted. Freudenthal expresses this situation to antidogmatical inversion and indicates negative opinion. However, it is open to doubt that every class situation can proceed to abstract that begins from concrete situations or concrete materials. This study has done a comparative analysis in difference of mathematical thinking between a process that builds abstract context after being abstracted from concrete materials and that concretes abstract concepts to concrete situations and attempts to examine educational implication. For this, this study analyzed the mathematical thinking in the abstract process of concrete materials by manipulating AiC analysis tools. Based on the AiC analysis tools, this study analyzed mathematical thinking in the concrete process of abstract concept by using the way this researcher came up with. This study results that these two processes have opposite learning flow each other and significant mathematical thinking can be induced from concrete process of abstract knowledge as well as abstraction of concrete materials.

Public open data is a database or electronic file produced by a public agency or government. The government is opening public data through the open data portals and individual agency websites. However, it is a reality that there is a limit to search and utilize desired public data from the perspective of data users. In particular, it takes a great deal of effort and time to understand the characteristics of data sets and to combine different data sets. This study suggests the possibility of interlinking between data sets by analyzing the common relationship of item names held by public data. The data sets are collected from the open data portal, and item names included in the data sets are extracted. The extracted item names consist of formal context and formal concept through formal concept analysis. The format concept has a list of data sets and a set of item name as extent and intent, respectively, and analyzes the common items of intent end to determine the possibility of data connection. The results derived from the formal concept analysis can be effectively applied to the semantic connection of the public data, and can be applied to data standard and quality improvement for public data release.

Gender sensitivity is a concept needs to be substantially count since early childhood when a child starts understanding and developing their gender role. As such UNESCO published the guideline on Comprehensive Sexuality Education(CSE) guidelines. In Korea, the Ministry of Women and Family selected the book called 'Nadaum children's book' in order to support children to better develop the gender sensitivity in their early childhood. This study aims for qualitative research on 101 books for low-grade children of Nadaum Children's Books. Content analysis and theme analysis were conducted based on UNESCO's CSE guidelines. This is to analyze the frequency rate of the CSE concepts and how the value of gender sensitivity is described throughout the books. The results shows that 'family member' and 'value of tolerance' were most frequently appeared while 'puberty' and 'sex and health' were not included. In addition, the results of theme analysis showed that this book well described the activities pursuing the value of gender sensitivity as well as process of being materialized it.

In the case that an abstract concept was measured indirectly by using its indicators, many researcher have obtained its score by using the simple mean, the first principal component, or the first factor, etc. In this paper, an scoring method named as the representative component scoring system was suggested as an alternative and its validity and applicability were studied.

인간 게놈 프로젝트가 완료됨에 다라 생체서열과 언어 사이의 대응 관계가 부각되고 있다. 본고에서는 Lewis Carroll의 언어 유희 사례를 컴퓨터생물학의 측면에서 재조명하고, Carroll이 제시한 문제 중에서 간단한 anagram 문제의 해결을 다루고자 한다. 우선 DNA 컴퓨팅의 방법론을 적용한 DNAgram의 개념을 확장하여 plasmid-DNAgram의 개념을 새롭게 도입하였다. 이 개념을 형광단백질에 대한 DNAgram의 개념을 확장하여 plasmid-DNAgram의 개념을 새롭게 도입하였다. 이 개념을 형광단백질에 대한 FRET(fluorescent resonance energy transfer)분석기법의 응용 사례인 cameleon 형광단백질에 대한 FRET 분석기법에 적용함으로써 anagram 문제의 어휘론적, 구문론적, 의미론적, 화용론적 측면에 대응하는 바이오분자 컴퓨팅 방법론을 제안하였다.
