This research intends to examine how 6th graders (age 12) generalize various increasing patterns. In this research, 6 problems corresponding to the ax, x+a, ax+c, ax2, and ax2+c patterns were given to 290 students. Students' generalization methods were analysed by the generalization level suggested by Radford(2006), such as arithmetic and algebraic (factual, contextual, and symbolic) generalization. As the results of the study, we identified that students revealed the most high performance in the ax pattern in the aspect of the algebraic generalization, and lower performance in the ax2, x+a, ax+c, ax2+c in order. Also we identified that students' generalization methods differed in the same increasing patterns. This imply that we need to provide students with the pattern generalization activities in various contexts.

국내에서 온라인 커뮤니티는 1990년대 말 인터넷과 개인 PC의 급속한 보급으로 인해 대중화되기 시작했다. 커뮤니티는 이용자 간 활발한 커뮤니케이션을 기반으로 구축되고 있으며 이러한 커뮤니케이션은 일상적인 언어적 맥락을 바탕으로 구성된다. 이러한 커뮤니티의 내용 분석은 연구자의 직관에 의해 수행되기 마련이나 연구대상의 양이 많아질 경우 연구자의 직관만으로는 이를 분석하는데 제약이 있을 수 있다. 네트워크 분석은 이와 같은 문제점을 해결 할 수 있는 방법 중 하나이다. 본 연구는 온라인 임신 Q&A 게시판의 내용적 특성을 살펴보기 위하여 네트워크 분석을 수행하였다. 먼저 수집한 데이터의 전체적인 내용적 특성을 살펴본 후, 게시글 작성자인 임산부의 임신 시기에 따른 게시글의 내용적 특성을 살펴보았다. 분석 결과 임신시기별로 핵심적인 단어의 빈도의 차이가 있었으며 네트워크의 구성 또한 다른 것을 확인하였다. 또한 성별에 따라서도 그 내용적 특성이 다른 것을 살펴 볼 수 있었다.

The purpose of this study is to construct a substantive theory that described and explained how pregnant women are seeking information in context of pregnancy. A qualitative design based on the method of grounded theory was utilized. In-depth interviews were conducted with 16 pregnant women, selected by theoretical sampling who receiving antenatal care 3 different university hospitals. The interview data were transcribed and systematically analyzed according to the open coding, axial coding and selective coding. 'Increasing Sense of Self-Control over Pregnancy' was the core category for describing and guiding the process of seeking information during the pregnancy. To construct a theory of 'Increasing Sense of Self-Control over Pregnancy' in this study, eight hypothetical statement were generated from the relationships among the core category and the other categories, thus four patterns were derived as follows: 'Desperately Seeking', 'Actively Seeking', 'Unconcernedly Seeking', 'Resignedly Seeking'. The implications of the findings are discussed in terms of development of LIS theory in Korea, theory development of information behavior, education for LIS, and information service practice. The suggestions for further research are provided.

Current research explores the effect of language on the perception of facial emotion as suggested by the psychological construction theory of emotion by using a psychophysical method. In this study, we hypothesize that the perception of facial expression may be influenced if the observer is shown an affective word before he/she judges an expression. Moreover, we suggest that his/her understanding of a facial emotion will be in line with the conceptual context that the word denotes. During the two experiments conducted for this project, a control stimulus or words representing either angry or happy emotions were briefly presented to participants before they were shown a target face. These target faces were randomly selected from seven faces that were gradually morphed to show neutral to angry (in Experiment 1) and neutral to happy (in Experiment 2) expressions. The participants were asked to perform a two-alternative forced choice (2AFC) task to judge the emotion of the target face (i.e., decide whether it is angry or neutral, or happy or neutral). The results of Experiment 1 (when compared with the control condition) showed that words denoting anger decreased the point of subjective equality (PSE) for judging the emotion of the target as anger, whereas words denoting happiness increased the PSE. Experiment 2, in which participants had to judge expressions on a scale from happy to neutral, produced a contrasting pattern of results. The outcomes of this study support the claim of the psychological construction theory of emotion that the perception of facial emotion is an active construction process that may be influenced by information (such as affective words) that provide conceptual context.

The ordinary term 'believe' is polysemous and thus its meaning varies depending on contexts. Little attention, however, has been paid to its context sensitivity in philosophical discussions, and thereby unnecessary problems tend to be brought about in philosophy. This article explores the different meanings of the term 'believe' to serve as a steppingstone to the solving or dissolving of those problems. To begin, it discusses two different mental attitudes 'believe' stands for, i.e., belief as an involuntary mental disposition and pragmatic acceptance as a mental action, and then suggests and explicates another mental action 'believe' referes to, which I call 'epistemic acceptance'. It will be revealed that epistemic acceptance is a secondary mental action which is performed in a context where epistemic reason and non-epistemic reason compete each other. Then, attention is given to several questions concerning epistemic acceptance and answers to them are provided. The issue of whether epistemic acceptance is analyzable and of the relation between epistemic acceptance and judgment will be addressed in the course of answering them. Finally, a brief prospect is put forward that distinction of different mental attitudes 'believe' stands for will bring a new perspective to solve some philosophical problems, especially, with regard to the issue of the nature of epistemic norm.

The purpose of this study is to deal with practical investigation, which blends symbolism on spatio-temporal level-especially typography in three-dimensional environment-and the symbolism of written language in the context of visual communication. Up until now, typography research and education have mainly been centered on two-dimensional environment and printing technology, such as the paper. However, this study is the result of this researcher's direct design and implementation of projects on typography aside from paper. Accordingly, this study is to provide an opportunity to raise the level of reason and expression used in visual communication to a new level and to expand its scope. To ensure the efficient progress of the project, this study was to identify the structure, system, and process of communication first. Furthermore, this study was to investigate two-dimensional and three-dimensional typography as the backbone of visual communication. In addition, several representative 3D typography works are analyzed in context and used as the conceptual framework of the project conducted for this study. Based on these results, this research verifies and suggests the possibility practically and objectively by creating the project series entitled Rhetorical Space in 3D typography. In addition, this research gives an opportunity to visualize ideas aimed at the development of character-based visual language and visual communication design in the realm of the more spatial, physical, and three-dimensional public environment.
