  • Pattern activities are useful to develop functional thinking of young students, but there has been lack of research on how to teach patterns. This study explored teaching methods of geometric patterns for developing functional thinking of elementary school students, and then analyzed the lessons in which such methods were implemented. For this, three classrooms of fourth grades in elementary schools were selected and three teachers taught geometric patterns on the basis of the same lesson plan. The lessons emphasized noticing the commonality of a given pattern, expanding the noti ce for the commonality, and representing the commonality. The results of this study showed that experience of analyzing the structure of a geometric pattern had a significant impact on how the fourth graders reasoned about the generalized rules of the given pattern and represented them in various methods. This paper closes with several implications to teach geometric patterns in a way to foster functional thinking.

  • Common factor analysis and principal component analysis represent two technically distinctive approaches to exploratory factor analysis. Much of the psychometric literature recommends the use of common factor analysis instead of principal component analysis. Nonetheless, factor analysts use principal component analysis more frequently because they believe that principal component analysis could yield (relatively) less accurate estimates of factor loadings compared to common factor analysis but most often produce similar pattern of factor loadings, leading to essentially the same factor interpretations. A simulation study is conducted to evaluate the relative performance of these two approaches in terms of factor pattern recovery under different experimental conditions of sample size, overdetermination, and communality.The results show that principal component analysis performs better in factor recovery with small sample sizes (below 200). It was further shown that this tendency is more prominent when there are a small number of variables per factor. The present results are of practical use for factor analysts in the field of marketing and the social sciences.

  • There is a considerable community between Eight Constitution Medicine and disease ecology in that they examine the relationship between humans and environment in terms of genetic, environmental and cultural factors, in addition to the factor of germs. In this respect, the purpose of this research aims to investigate the community between Eight Constitution Medicine, a branch of Eastern Medicine and disease ecology in geography. The research method is to analyse the clinical results from 647 patients and the data from a field survey on the Yeonggwang-gun County, Jeollanam-do Province. The results are summarized as the following: First, geographical distribution of patients varies depending on the type of physical constitution; it is also divided into two types, an oceanic type and an inland type. Second, it is highly probable that there is a significant relation between a vulnerable disease in association with a type of physical constitution and patient's native place; there are diseases that are not associated with all the patients who have the same constitution; they might be incurred by the eating or life habits in association with the characteristics of geographical environment. Third, the case study of Yeonggwang-gun County, Jeollanam-do Province, with a focus on the mutual relationship among the three factors. shows that patients, who share in common the eating or life habits that coincide with their own personal types of constitution, maintain a good health condition; if not, they tend to be exposed to a various kinds of disease. Because the study on the community between Eight Constitution Medicine and disease ecology is now at the early stage, diverse types of approaches should be tried to be applied in the future.

  • Component-based software development (CBD) technology has been widely accepted as a new effective paradigm for building software systems with reusable components, consequently reducing efforts and shortening time-to-market. Hence, components should provide standard or common functionalities in a domain, yielding a higher level of reusability. Especially, micro-level variability within the commonality should also be modeled so that a product member-specific business logic or requirement can be supported through component tailoring or customization The importance of commonality and variability (C&V) analysis has been emphasized in several CBD methods, but they lack of well-defined systematic process, detailed instructions, and standard artifact templates. As the result, the development of components has been carried out in ad-hoc fashion, depending on developer's experience. In this paper, we propose a systematic process and work instructions to design components. The process consists of phases and their activities and each activity is specified with detailed instructions and artifact templates in order to facilitate effective development of components. To verify a feasibility of the propose method, a case study in a banking domain and comparison and assessment between the proposed method and other methods are additionally provided. With proposed processes and instructions, reusability and efficiency of developing components can be better supported.

  • According to TIMSS, secondary math teachers in Korea has lower confidence compare to other countries, despite the fact that teachers' confidence of teaching is an important variable. This not only influences the student's improvement but, also the quality improvement of teachers' career. Therefore, this study explores the effect of secondary math teachers' confidence according to the context variables such as teaching years, teaching preparation, collaboration with other teachers, and teaching limitation. Additionally, these context variables' $R^2$ toward the change of teaching confidence is also included. Results indicate that teaching preparation, collaboration with other teachers, and teaching limitation contribute in the confidence of teaching. $R^2$ of the change of teaching confidence shows large contribution to teaching preparation which does not accomplish with other variables.

  • 성공적인 의사소통의 경우에 성(性)이, 이(理)와 명(命)으로 나타난 것이 같다. 진리(aletheia)가, 언어(logos)와 운명(moira)으로 나타난 것들이 일치하는 것이 성공적인 언화행위가 된다. 측정대상(melos)과 본체(ousia)가 구분되는 것은 언어와 운명의 괴리가 있을 수 있기 때문이다. 체계적인 언어처리의 지식기반을 측정대상에 한정한다. (1) 철학의 시작은 더 옳은 언어표현의 정의(definition)로 이전의 잘못 사용된 언어처리를 대체시키는 것으로 소크라테스는 보았다. [R. Crossman] (2)잘못을 지적하는 등에(Tabanidae)의 역할과 옳은 지식의 상기를 돕는 산파법(maieutics)이 소크라테스의 의미분석의 방법이다. [R. Crossman] (3) 언어를 통하여 진리를 추구한다는 입장(via language)에서 한 언어표현이 그 진리의 운명으로 나타남과 어긋날 때, 운명을 택하는 것은 조화 보다 더 안정의 우위를 인정하는 논리적인 입장으로 합리성 보다 실용(pragma)의 우위를 인정하는 것이다. [W. Quine] (4) 공동체의 공통규범의 추구는 그 언어 속의 공통의 형식 또는 법칙의 추구에 기초하는 것이 자연스럽다. 여기에서 그 언어사용은 그 기저의 법칙(underlying rule)에 개입한다는 입장에 기초한다. [J. Searle] (5) 진리의 언어표현과 운명적인 사태들 사이의 괴리를 처리하기 위하여 체계적인 언어표현의 대상(The Young Tableaux)과 실제(The continuum)의 구분을 수용한다. [AMS(2000)]언어표현의 대상은 나타난 것(顯)이고 실제에는 나타나지 않은 것도 있다. [伊川, 明道] (6) 이 나타난 것과 나타나지 않은 것에 간격이 없다는 것(顯微無間)은 그 의사소통이 성공적인 것이라는 것을 말한다. 따라서 그 언어의 표현완전성(functional completeness)은 언화행위가 성공적이라는 것이다. [J. Searle] (7) 수로 쓰인 것(象數)과 시로 쓰인 것(義理)이 하나인 것은 그 나타난 것과 나타나지 않은 것들 사이에 어떠한 틈도 없음을 말한다. [成中英] (8) 공통의 규범의 공통성 속에 규범적인 측면이 벌써 있다. 공통성에서 개인적이 아닌 공적인 규범으로의 전이는 규범, 가치, 규칙, 과정, 제도로의 전이라고 본다. [C. Morrison] (9) 우리의 언어사용에 신비적인 요소를 부인할 수가 없다. 넓은 의미의 발화의미(utterance meaning) 속에 신비적인 요소나 애정표시도 수용된다. 의미분석은 지금 한글을 연구하고, 그 결과에 의존하여서 우리의 실제의 생활에 사용하는 $\boxDr$한국어사전$\boxUl$등을 만드는 과정에서, 어떤 의미에서 실험되었다고 말할 수가 있는 언어과학의 연구의 결과에 의존하여서 수행되는 철학적인 작업이다. 여기에서는 하나의 철학적인 연구의 시작으로 받아들여지는 이 의미분석의 문제를 반성하여 본다.

  • This study sought to develop an integrated information literacy curriculum that would have a strong relationship with curricula through the standard themes abstracted from theme network structures, scan and cluster analyses of the information literacy curricula. In addition, this study also attempted to develop a teaching-learning model for the developed integrated information literacy curriculum. This study utilized the themes of information literacy instruction that have interdisciplinary characteristics as analysis criteria in analyzing the commonality of information literacy instruction and the subject curricula. The following characteristics were found from the analyzing the areas of commonality. Foremost, the first themes(the fields of basic learning skills and nature) which belongs to the fields of information society, library, information technology, collaborative skills were found to have many relationships with the subject curricula. Next, the second themes(the field of information problem solving capabilities) which is the core field of information literacy instruction showed a weak relationship with the subject curricula.
