  • Various theories of mathematics education which have been considered by many European researchers particularly, in France, recently are introduced. The Anthropological Theory of the didactic discussed by Chevallard will be briefly introduced. Then the praxeology as Anthropological model according to Chevallard's theory will be discussed. The necessity of Anthropological Theory, its background of development through transition process of didactic, and its basic elements will be discussed further. Additionally, teaching limit of sequences in high school mathematics will be suggested according to the theory.

  • There are many mistakes when we estimate probability of an event, for example, we often omit some likelihoods (of an event), sometimes give too large or too small possibility for a particular case, cannot relate current cases with which were concerned before, apply at another cases as soon as discuss about it insufficiently, etc. If we go into a history of probability and statistics, we shall ascertain that many scientists and mathmaticians made essentially same mistakes with us. In the paper, we will consider the theorization of probability and statistics as a process of modification of mistakes which were made during one's estimating possibility of an event. On that point of view, we shall look at historical background of probability and statistics.

  • Regulation theories has paid little attention to spatial regulation processes, while it has focused on economic and social regulation processes. More specifically, there have been little researches on regulationist approach to the transformation of the post-socialist system in the context of the space economy. Therefore, the article has attempted to conceptualize the transformation of space economy under the post-socialist system in the light of regulation theories. The space economy could be regarded as the foundation of the reproduction of social relations. Thus, the transformation of post-socialist system has led to the fundamental changes in enterprise and industrial networks as well as social relations in spatial contexts. In this perspective, the research has attempted to identify 'the mode of enterprise regulation' regarded as a codified firm networks by investigating intra-, inter- and extra-firm relations associated with the transformation of post-socialist system. Also, it has intended to suggest three types of the space economy - (1) disembedded economies based on the isolated networks and dissolution of pre-existing networks, (2) embedded economies based on the interaction of institutions and restructuring of networks, and (3) over-embedded economies based on the insulated institutions and endurance of pre-existing networks-in accordance with the governance, institution and networks in the post-socialist system.

  • The flaring system of FPSO burns out the byproduct natural gas. The thermal loading due to radiative heat of flaring gas leads to undesirable thermal-stresses on itself. Nowadays it needs to understand the amount of thermal loading of flaring system since the requirement for the safety of the flaring system. However, few studies have been performed on the thermal environment and radiative heat flux on the FPSO flaring system. Present study suggests a procedure to model the thermal environment and a FEA process to analyze the temperature distribution and thermal stresses of FPSO flaring system. In order to get the temperature distribution, the radiative heat conditions and convective heat conditions are included in the heat transfer analysis. By making the use of temperature obtained through heat transfer analysis, the thermal stress analyses are performed. The results of the present study can be used to design the flaring system and determine the heat shield in the flaring system.

  • This paper reviews the evolution process of global production network(GPN) discourse, from its origin to the recent theorization, namely GPN 2.0. In so doing, the discursive formation of global production networks is introduced in comparison with a competing discourse global commodity/value chains, with particular attention to conceptual and analytical lacunae in the latter. This article also outlines how the global production network perspective has become a useful discursive and practical tool that allows the examination of the nexus of global economy, transnational corporations, and regional development. Subsequently, a theoretical dearth in the approach is discussed in reference to key critiques, and in this context Yeung and Coe's recent theorization GPN 2.0, which is centered on casual mechanisms and network configurations is reviewed. This paper suggests that the theory adequately addresses the problem of casuality lacking in its precedented conceptual framework, and that it helps exploring the formation and evolution processes of varied production networks(including intrafirm coordination, interfirm control, strategic partnership, and extrafirm bargaining) in connection with competitive dynamics and risky environments. As a result of the theorization, the difference between GPN and the chain approaches has become more apparent, and the idea of extrafirm bargaining is particularly important in the differentiation. Extrafirm bargaining is seen to be a comprehensive networking form inclusive of such GPN 1.0 analytical concepts as value, embeddeness, and power, and research attentive to, and engaging with, the extrafirm networks is expected to help transcending the chain governance approaches' analytical excess of interfirm linkages and industry-centeredness.

  • 본 연구는 오늘날 범지구적 차원에서 심각한 수준에 있는 생태계 파괴에 대한 사회학적 함의를 정립하는 데 목적이 있다. 이를 위해 먼저 생태계의 개념과 구조를 살펴보고, 다음으로 인간활동으로 인한 생태계 파괴의 메커니즘을 분석하고, 마지막으로 그 메커니즘에 기초하여 생태계 파괴에 대한 사회학적 함의를 정립하였다. 생태계로서의 자연은 인간 없이 존재할 수 있지만 인간은 자연 없이는 생존할 수 없다. 따라서 생계위기는 곧 인간의 위기다. 그럼에도 불구하고 18세기 산업혁명 이후 풍요성과 편리성 추구를 위한 인간의 활동 결과 지구는 점용환경용량을 2.5배 초과되었다. 이것은 인간이 범한 모순이다. 이 모순을 해결하면서 사회발전을 추진하자는 이념으로 1987년 지속가능발전이 제창되었고, 지속가능발전은 1990년대 중반에 지속가능사회로 대치되었고, 2000년대에 와서는 지속가능사회가 생태적 근대화로 대체되었다. 18세기 산업혁명 이후 풍요성과 편리성 증대를 위한 인간의 활동으로 생태계가 파괴되기 시작한 후, 생태계를 보전하면서 사회발전을 추진하자는 생태적 근대화 이념이 출현까지의 역사적 과정은 정(正)-반(反)-합(合)의 변증법 과정으로 이론화될 수 있다. 산업혁명 이전의 농업사회 때는 인간의 활동이 점용환경용량 범위 안에서 이루어졌기 때문에 환경문제가 없었다. 이 시대는 생태적 지속가능성이 유지되었기 때문에 생태적 합(合)의 상태라고 할 수 있다. 산업혁명 이후 인간의 활동이 생태계의 점용환경용량을 초월시킨 것은 생태계에 반(反)이 작용한 것이다. 따라서 범지구적 차원에서 환경문제의 심각성을 인식하고 지속가능발전을 위한 정책이 도입되기 이전까지 생태계는 정(正)과 반(反)이 대립상태에서 공존하였다. 1990년대 이후 생태적 지속가능성을 위한 각종 지속가능발전정책의 도입은 정(正)과 반(反)의 대립을 통해 다시 생태학적 합(合)의 상태를 지향하는 과정이라고 할 수 있다.

  • Postcolonialism, as a school of thought, has become enormously influential for understanding the recent phenomena of globalization. While rejecting the universalizing categories of the Enlightenment, postcolonialism has called into question the old idea of culture and identity as a transcendent regime of authenticity and purity. It has also celebrated the diasporic experiences that entail porous and hybrid cultural identities as a potential site of struggle and resistance against the dominant cultural and discursive order. It is argued, however, that postcolonial theory's emancipatory claims relating to the diversified global culture tend to be complicit with transnational capitalism that brings about global issues of material as well as cultural injustice. This article, through a thorough review of the ways the postcolonial theoretical framework has been developed and appropriated by main figures in postcolonial scholarship, seeks for a theoretical and critical strategy to grasp the complex conditions of global inequality.

  • The purpose of the study was to investigate how students generalize and prove the factoring of $x^n-1$ using a Computer Algebra System application and the role of CAS in this process. The theoretical framework consists of the anthropological and the instrumental approach. In particular, the basis of the Task-Technique-Theorization(T-T-T) frame adapted form Chevallard's anthropological approach of Didactics is utilized. We found that Technique-Theorization emerges in mutual interaction between paper-and-pencil techniques and computer algebra techniques. And this interaction led to the students' theoretical reflection and conceptual understanding. In this process, we could identify three epistemic role of CAS : the role of checking the result, the role of cognitive stimulation and the role of extending thinking. Therefore CAS plays on a epistemic role of checking the result of a task, stimulating the student' cognition and extending their thinking as well as pragmatic role of producing the result of a input.

  • The paper has tried to analyze the sense of 'meta-praxis' in the educational discourse. Against the dichotomy of theory vs practice, the senses of practice and 'meta-praxis' can be hold under the Greek conception of human activities such as theoria, poiesis and praxis. We can establish the meaning of meta-praxis contrasted with one of metaphysics, not with one of meta-theory. Some significant points included in the concept then have been minutely examined so as to lead us to get the recursive structure and practicability. The Buddhist notion such as 'Well-Rounded Discretion' and the linguistic one such as 'Grand Father' throw light on the educational practice and discourse. These are ones that we never fail to recognize in terms of 'meta-praxis'.

  • 본 논문에서는 노동자문화정치의 관점에서 파업을 새롭게 정의하고, 파업을 비롯한 노동자 문화실천의 정치적 효과를 분석하기 위한 방법론적 요소들을 검토하였다. 여기서 파업은 참여주체들의 다양한 사고와 합리성들을 중심으로 형성되고 확장되는 내재적인 정치의 장인 동시에, 다양한 기표적 실천들이 전개되는 문화정치의 장으로 정의되었다. 파업의 발생과 전개의 각 과정과 국면에 대한 문화정치적 분석 요소로서 장소성, 공간, 시간, 정서, 기호자원, 담론이 고려되었고, 이 요소들에 초점을 두고 민주노조 파업에서 드러나는 문화정치적 제약들을 H사 노조 사례를 통해 검토하였다. 문화정치적 제약들은 노동자 문화의 생산과 수용에서의 제약으로 드러난다. 노동자문화 관련 텍스트들의 분석과 조사 자료를 통해서 볼 때, 그것들은 첫째로 노동자 문화 활동가들의 생산 실천 상의 제약과 관련있고, 둘째로, 노동자 대중의 노동자 문화 수용 혹은 소비에서의 도구성과 시 공간 상의 제약과 관련있는 것을 확인했다. 본 논문은 이러한 제약들이 70년대 이후에서 90년대 전반에 이르는 시기와는 달리, 현 시기 노동운동의 문화적 자원들이 신기술과 사회문화적 변화에 걸맞게 변화 확장되지 못하고 오히려 축소된 데 기인한다고 추론하였다. 따라서 지속적인 운동의 조건과 기반을 능동적으로 조성하기 위해서는, 파업을 비롯한 노동자 문화의 생산과 수용 전반에 걸쳐서 작용하는 재현체계 상의 제약, 특히 기호자원의 한계라는 근본적인 제약을 넘어서기 위한 노동자 문화정치의 필요성이 제안되었으며, 문화실천에 몸담고 있는 문화활동가나 노조활동가들이 파업과 일상 활동 속에서 문화정치적 주제들을 찾아 이론화하고 정책에 반영하는 문화활동 방안이 제안되었다.
