This study analyses on the history of uniform convergence, and discusses its educational implications. First, this study inspects 'overflowing of the Euclidean methodology' which was suggested by Lakatos as a cause of tardy appearance of uniform convergence, and reinterprets that cause in the perspective of 'symbolization'. Second, this study looks into the emergence of uniform convergence of Seidel and Weierstrass in this viewpoint of symbolization. As a result, of analysis, we come to know that the definition of uniform convergence had been changed into the theory of 'domain and graph' from that of 'point and function value' by the location change of the quantifier. As these results, this study puts forward an educational suggestion from an angle of epistemological obstacle, concept definition and concept image.

이 글은 사회정책연구에 있어 담론연구를 위한 서설로, 담론연구의 철학적 배경을 간단히 정리하고, "정책"을 무엇으로 볼 것인가, "정책"을 어떻게 이해할 것인가, "정책연구자"는 어디에 위치하며 무엇을 해야 하는가의 내용을 통해 담론연구의 방법론적 위상과 의미를 살펴본다. 담론연구는 텍스트, 맥락, 담론, 이데올로기로서의 정책과, 복합적이고 역동적인 정치의 장에서 일어나는 정책현상을 해석적이며 비판적으로 이해한다. 정책현실에 대한 이같은 이해는 정책연구에 있어 '논증적 전환'을 가져왔고, 이와 같은 사유방식은 논리실증주의에 기반한 기존의 가치중립적이고 인과적 설명 방식을 취하며 보편적 법칙을 추구하는 방법론과는 구별된다. 이같은 인식론적 입장은 주체와 객체의 관계를 상호주관적이고 호혜적 구성관계로 보며, 정책현실과 정책대상을 담론의 구조 안에서 제한적으로 구성된 실체로 본다. 담론연구는 지배담론의 질서 내에서 문제가 어떻게 규명되고 현실이 어떻게 재단되며 정책대상이 어떻게 규정되는지를 해체하는데 주목한다. 이 해체의 과정은 담론질서가 품고 있는 권력성에 대한 비판적 인식과 담론구조 내 한계를 가질 수 밖에 없는 사유주체로서의 연구자 스스로에 대한 반성적 성찰을 포함한다. 또한 담론연구자는 사회정책의 중심에 자리하고 있는 사회적 약자의 '형식과 과정'으로서의 참여 뿐 아니라 그들 목소리를 '내용'으로 하는 대안담론의 가능성을 모색한다. 이러한 참여와 소통 그리고 반성적 성찰은 정책연구에 있어 해방적 관심을 의미한다.

Public acceptance of nuclear power is important for the government, the major stakeholder of the industry, because consensus is required to drive actions. It is therefore no coincidence that the governments of nations operating nuclear reactors are endeavoring to enhance public acceptance of nuclear power, as better acceptance allows stable power generation and peaceful processing of nuclear wastes produced from nuclear reactors. Past research, however, has been limited to epistemological measurements using methods such as the Likert scale. In this research, we propose big data analysis as an attractive alternative and attempt to identify the attitudes of the public on nuclear power. Specifically, we used common big data analyses to analyze consumer opinions via SNS (Social Networking Services), using keyword analysis and opinion analysis. The keyword analysis identified the attitudes of the public toward nuclear power. The public felt positive toward nuclear power when Korea successfully exported nuclear reactors to the United Arab Emirates. With the Fukushima accident in 2011 and certain supplier scandals in 2012, however, the image of nuclear power was degraded and the negative image continues. It is recommended that the government focus on developing useful businesses and use cases of nuclear power in order to improve public acceptance.

All kinds of artwork, including multimedia and digital image that has been subliminated into an af mediating two numbers 0 and 1 in recent age, are self-sufficient and autonomous in themselves. Nevertheless, each of those artworks can be realized as a real entity only if its appreciator is capable enough to explore some potential meaning out of it through his or her own perceptual work. According to Mikel Dufrenne, an artwork is composed of three existential tiers: "le sensible" or the sensible material; "fe representation" or the subject(le sujet), and "1′expression." Dufrenne contends that our esthetic perception can be realized by way of three steps that are comparable to those three tiers: perception of the presence of the body("le sensible"), contemplative perception by way of imagination("le representation"), and reflective perception ("1′expression") as a result of dialectics of sense and sensibility. This paper argues on the aesthetic perception with regard to digital image expressed by two numbers 0 and 1, putting focus on the epistemological role of sensibility(감) that explores "1′expression" a la Dufrenne.

This study analyzed the visual images covering 'the changes of weather' in elementary science textbooks by 2007 curriculum revision from a perspective of linguistics. The findings showed that there were inclined to increasing in terms of ideational and textual metafunctions. It meant that the informative images were increased and the form of images became more abstractive. It also showed an increase in terms of interpersonal metafunctions. It was interpreted as decreasing the ratios of images inducing epistemological detachments and increasing images help familiarity and involvement between images and readers. These results showed that the visual images of 'the changes of weather' in 2007 revised elementary science textbook were professionally, technical, and abstractive in terms of the contents and formality. And these trends of images were complemented by the involvement and familiarity of images in the aspect of interpersonal metafunctions.

The paper is oriented towards a reflection on the epistemological extension of world history. This discipline is currently opening up for new subjects and new foci of interest, with environmental history being one of them. The paper debates the interaction between the global and the local as one of the main issues of world history. It analyses the impacts of the interconnectivity of diverse regions as well as different geographical and cultural complexes, during the period between 1500 and 1800. Assuming that the sea in its economic, cultural and environmental dimensions contributed actively to world history, and is, in itself, a major factor of globalization, the paper intends to highlight interdependencies which fostered connections between the local and the global. It further submits to discussion which was the impact of an on-going globalization process, based on maritime dynamics, on the environment. Through an analysis centered on the impact of European overseas expansion, some environmental impacts will be analyzed. The paper aims at questioning environmental history as an emergent theme of world history, based on the historical experience of connecting worlds developed in the First Global Age (1500-1800).

This essay traverses the ontological space of IS research and identifies various misconceptions, biases, and conceptual peculiarities that inhabit the research. Three aspects of the IS ontology are examined: the conceptualization of the IT construct, demarcation of phenomena for investigation, and conceptual binding of the IT construct to other constructs. Various ontological issues are discussed including the transparency of the IT construct, the objectification of IT, and the causal primacy assigned to IT. The ontological purviews are further explored and their inadequacies are traced in the structurational explication of IS phenomena. At the end, some epistemological implications of the IS ontology are discussed and a two-tier theory structure is proposed for IS research.

The notion of metaphor has been increasingly popular in research of mathematics education. In particular, metaphor becomes a useful unit for analysis to provide a profound insight into mathematical reasoning and problem solving. In this context, this paper takes metaphor as an analytic unit to examine the relationship between objectivity and subjectivity in mathematical reasoning. Specifically, the discourse analysis focuses on the code switching between literal language and metaphor in mathematical discourse. It is shown that the linguistic code switching is parallel with the switching between two different kinds of mathematical knowledge, that is, factual knowledge and mathematical imagination, which constitute objectivity and subjectivity in mathematical reasoning. Furthermore, the pattern of the linguistic code switching reveals the dialectical relationship between the two poles of mathematical reasoning. Based on the understanding of the dialectical relationship, this paper provides some educational implications. First, the code-switching highlights diverse aspects of mathematics learning. Learning mathematics is concerned with developing not only technicality but also mathematical creativity. Second, the dialectical relationship between objectivity and subjectivity suggests that teaching and teaming mathematics is socioculturally constructed. Indeed, it is shown that not all metaphors are mathematically appropriated. They should be consistent with the cultural model of a mathematical concept under discussion. In general, this sociocultural perspective on mathematical metaphor highlights the sociocultural organization of teaching and loaming mathematics and provides a theoretical viewpoint to understand epistemological diversities in mathematics classroom.
