In spite of various attempts to characterize the ontological status of space-time, Newtonian substantivalism and Leibnizian relationism, what is really at issue in the controversy between the two parties is by no means clear. This essay argues that from the perspective of space-time symmetries, classical space-time can be unambiguously classified as substantival space-time and relational space-time. The symmetries of space-time theories distinguish the invariant geometric relationships between events. The essential difference between the two space-times stems from whether or not there exists the affine structure that distinguishes the inertial trajectories of a given body.

본 논문은 조선시대의 장여헌(張旅軒)과 일본 에도(江戶) 시대의 이토 진사이(伊藤仁齋)의 사상, 특히 도(道)에 관한 견해를 중심으로 인간론과 도덕론을 고찰하여 그 둘의 사상적 특징을 밝히고자 하는 시도이다. 논의의 진행은 먼저 도(道)에 관한 여헌과 진사이의 이해를 주자학적 논의와의 원근 거리와 천도(天道) 인도(人道)와의 관계에서 살펴보았고, 다음으로 인간관에 있어서는 자기와 타인과의 관계를 중심으로 인간에 관한 이해를 논하였으며, 다음으로 마음과 경(敬), 서(恕)에 관한 두 사상가의 상반된 이해를 소개하면서 도덕론을 논하였다. 이하 요점을 추려보면 다음과 같다. 진사이는 도를 천지의 도와 단절된 인륜일용의 인간의 도로 한정하였고 인간에 대해서도 개적 존재를 사상시킨 관계적 존재에 초점을 두고 파악하였다. 그런 관점 위에서 개인 수양의 출발점이 되는 마음이나 경에 대해서도 큰 비중을 두지 않았고, 그것은 개인의 자율성보다는 외적인 규범에 보다 많은 신뢰를 두고 그것에 자신을 맞추어 가는 일종의 타율적인 관계(집단) 속의 도덕론의 전개로 나타나고 있음을 논하였다. 여헌은 도(道)를 천지만물과 사람 모두가 의거하는 총체적인 개념으로 파악하였고, 더 나아가 사람의 도가 능동적으로 천도와 지도를 구현하는 중심이라고 하였다. 이런 관점 위에서 여헌은 인간은 몸(형기(形氣))을 가진 개적 존재이지만 동시에 그 몸의 일부인 천지만물과 통하는 마음을 갖고 있다는 점에서 보편적인 존재라고 정의하며, 그 마음을 다스리는 경(敬)공부를 개인 수양의 기본임과 동시에 천지만물의 보편적 이치를 체득하는 근본적인 실천공부로 중시하였다. 이러한 여헌의 도와 인간에 대한 이해는 도덕의 실현에 있어서 자신이 중심이 되어 그것의 확장으로 모두가 하나가 되는 동심원적 파동의 도덕론으로 전개되고 있음을 고찰하였다.

This essay considers Leibniz-Clark correspondence on the nature of space and hole argument. The ontology of space had been debated under the name of substantivalism-relationism controversy. The debates between the two parties are concerned with the nature of existence of parts of space-time. Substantivalism claims that the point of space-time has existence analogous to that of material substance. Relationism argues that space-time should be understood as the framework of possible spatio-temporal relations between bodies. Although these two approaches attempt to respect theoretical context, it seems that the problems of these two interpretive schemes stems from the lack of understanding of the structure of space-time theories, especially how space-time is connected with the laws of motion. In order to appreciate the substance-relation controversy without deviating from the context of space-time theories, it is necessary then to capture how space-time theories are constituted. This essay offers the clear connection of ontology of space-time with present practices of theoretical physicists.

This qualitative study investigated preservice teachers' understandings of the ontology and epistemology underlying constructivist notions of learning through four in-depth interviews. Of the sixteen participants in a larger study, five significantly changed ontological and epistemological beliefs and eleven did not. This study focused on these eleven teachers who have hardly changed their philosophical beliefs throughout the teacher education program. Ten teachers who consistently maintained the scientific realist beliefs were presented as a composite case (Young's case). Among the eleven teachers, there was one outlier who had consistently maintained an idealist and relativist epistemological position from the beginning of the study and was subjected to another case analysis (Ben's case). These cases corroborated the assertion that each individual's deeply entrenched ontological and epistemological beliefs are very hard to change. For researchers, this study offers insights into the reasons that preservice teachers give for non-changes in their thinking about learning to teach. The study also examines preservice teachers' perceived constraints in implementing their ideal pedagogies and the influence of the teacher education program on their pedagogical beliefs changes. The benefits and influences of the M.Ed. program's theoretical coursework and the field experiences on these teachers' learning-to-teach experiences are addressed with rich data. The implications for teacher educators as well as for the instructional practices of preservice teacher education programs are discussed. This research emphasize necessity of the field-based teacher education program and the need of empowering experienced school teachers as teacher educators in teacher preparation and professional development.

This essay attempts to evaluate the pessimistic induction within the case of the historical development of space-time theories, which are claimed to undergo a radical ontological change providing evidence for the pessimistic induction. In my view, this claim misleads us to see the discontinuity of the structure of classical and relativistic space-time by means of a doubtful interpretation of space-time theories, which holds that space-time causally explains the phenomena of motions.

The purpose of this thesis is to explain the difference between Heidegger's hermeneutical philosophy and Gadamer's philosophical hermeneutics. The difference is to say that Heidegger's philosophy begins with Aristotle's theory of category and transcendental philosophy. On the other hand, the beginning of Gadamer's philosophical research is Plato's dialog, philosophy and Hegels dialectic. 2. Heidegger regards humanism as a variant of the modern ideal of human beings. On the contrary, Gadamer understands humanism as a place where romantism leads to the ideals of human education. 3. Heidegger says that the hermeneutical circle is still a logical and existential structure of the circle. On the contrary, Gadamer understands the circle as a circle between the whole and the part. This circle is the law of traditional hermeneutics derived from the tradition of rhetoric. 4. Heidegger says Plato's philosophy is the first beginning of the substance metaphysic, Hegel's philosophy the end of the subject metaphysic. On the contrary, Gadamer says the hermeneutical understanding and the hermeneutical interpretation is endless. 5. Heidegger's ontology is as Sein zum Tode a future oriented and eschatological. On the contrary, Gadamer's hermeneutic is as Sein zum Text always the way to a past, the infinite openness.

Our freedom is natural, however we are amazed at the fact that we don't sometimes have the freedom. we have to have a freedom and must be a freedom. But we think our life is restrained. Why do we think that? This is due to epistemological thinking. Also critic of Sartre' freedom is due to that. Especially Merleau-Ponty's researchers say that Sartre is an epistemologist on the problem of the freedom and his freedom is an absolute freedom. Aim of this paper is to find out problem of the critic. To achieve this, first we need to exmaine what absoulte freedom is. It is abstract and ideological. According to Merleau-Ponty, it dosen't exist. This paper argues that Sartre's freedom is not epistemoligical but ontological. It is going to come out in relation between '$l^{\prime}{\hat{e}}tre-en-soi$' and '$l^{\prime}{\hat{e}}tre-en-soi$'. Then, on the problem of the freedom, we can discover that Sartre and Merleau-Ponty are no different from each other. Finally, As I argue about Merleau-Ponty's freedom, I will show that it is 'a freedom of situation' and 'a freedom of choice'. Also, This freedom is Sartre's freedom. Sartre showes a situation is my freedom.

This paper criticizes the ontological and epistemological dichotomy in social sciences including social welfare and probes into Critical Realism as an alternative paradigm. Many theories for social welfare have adhered to dichotomous ontological standpoint, 'agency' vs. 'social structure', and Eco-system approach have occupied dominant position to integrate this dichotomy. These theoretical standpoint have had great influence on social work practice. On the other hand, dichotomous epistemological standpoint which is constituted of different views of phenomena, 'positivism' and 'constructionism', have had great influence on social work research and practice. These dichotomous ontological and epistemological approach have a limit to reveal qualitative nature of the relationship between agency and social structure, to ponder the deeper reality, the mechanism of stratified reality, and the reality being independent of agency. Replacing these approaches, Critical Realism unfold the theoretical potential as an alternative paradigm for social welfare through the discussion on stratified realty(the empirical, the actual, and the real), intransitive/transitive dimension, double hermeneutics in these dimensions, and the conditions for conceptualization, duality of structure and practice, transformation model of agency and structure.

The purpose of this study is to analyze representation of characters of AOS online-game in order to find out the meanings of ontological game characters. This study selects characters of on-line game to analyze representations of game characters by Pierre L$\acute{e}$vy's ontological theory. The characters which represented in on-line games reproduced by costume play in off-line world reflect human desire and construct human existence. Online game character is an existing substance, which could expand human experiences by crossing virtual game world and reality in digital era.
