  • The importance of teaching the nature of science (NOS) has been emphasized in the science curriculum, especially in the science curriculum for science-gifted students. Nevertheless, few studies concerning the structure and formation of students' mental model on NOS have been carried out. This study aimed to explore science-gifted students' understanding of 'fact', 'hypothesis', 'theory', 'law', and 'scientificness' by utilizing semantic network analysis. One hundred ten science-gifted middle school students who were selected by a national university participated in this study. We collected students' written responses of five items and analyzed them by the semantic network analysis(SNA) method. As a result, the core ideas of students' understanding of 'fact' were proof and reality, of 'hypothesis' were tentativeness and uncertainty, of 'theory' was proven hypothesis by experimentation, of 'law' were absoluteness and authority, and of 'scientificness' were factual evidence, verifiability, accurate and logical theoretical framework. The result of integrated semantic network illustrated that the viewpoint of science-gifted students were similar to absolutism and logical positivism (empiricism). Methodologically, this study showed that the semantic network analysis method was an useful tool for visualization of students' mental model of scientific conceptions including NOS.

  • Contrary to the popular view that dative is idiosyncratic to verbs or particular theta roles, the distribution of dative is predictable from the distribution of other cases like nominative, accusative, instrumental, etc. That is, dative behaves like an unmarked or elsewhere choice for Non-Actor/Non-Patient (=NANP) roles. This paper develops a theory of semantic structural case under the framework of conceptual semantics (Jackendoff 1983, 1990, 1997, 2002). In my proposed analysis, dative is structurally mapped onto NANP entities in the conceptual structure. Important consequences about other peripheral roles are discussed in section 5.

  • This paper introduces a computer program ARAP, explaining how it automatically analyzes and evaluates academic research articles and books. It also shows how ARAP can help trace the trend of a certain theory by reviewing existing publications. As an illustration, ARAP is used to review Korean linguistic publications in order to show how Western semantic theories have influenced semantic studies in Korea.

  • This paper explores Discourse Rep-resentation Structures which can successfully describe the mental representations that discourse participants form when they hear so-called double access sentences. The syntactic, semantic and pragmatic characteristics of double access sentences are discussed. The analysis proposed in this paper, employing a modified version of the 'conditional beliefs' of Chung(1997), successfully explains the semantic and pragmatic characteristics of present or future tense in double access sentences as well as when and why the speaker should take or can be exempted from the responsibility for using present or future tense in double access sentences.

  • In this paper we describe an application of the lexical resource JurWordNet and of the Core Legal Ontology as a descriptive vocabulary for modeling legal domains. It can be viewed as the semantic component of a global standardisation framework for digital governments. A content description model provides a repository of structured knowledge aimed at supporting the semantic interoperability between sectors of Public Administration and the communication processes towards citizen. Specific conceptual models built from this base will act as a cognitive interface able to cope with specific digital government issues and to improve the interaction between citizen and Public Bodies. As a Case study, the representation of the click-on licences for re-using Public Sector Information is presented.

  • This aim of this study is identify research trends and intellectual structure in the field of Korean journalism and communication studies. For this purpose, a semantic network analysis was employed to analyze keywords in the abstracts of published articles in the Korean Journal of Journalism and Communication Studies from 2005 to 2015. The results showed that "frame", "Twitter", "content analysis" and "social media" are among the most frequently used keywords in the abstracts during this period. With regards to degree and eigenvector centrality, "social capital", "trust" and "twitter" were among the highest. The findings of the periodic characteristics of research trends revealed that there are more studies that employ the traditional media effect theories including Uses and Gratification Theory, Agenda Setting Theory, and Framing Theory before the year of 2010 while those that focus on the specific new media such as smartphones and twitter after 2011. This study has implications in the sense that it can be used as guidelines for making a curriculum or establishing the research system for Korean journalism and communication studies in the future.

  • One of the most important aspects of the research on multi-agent systems is the definition of agent communication languages(ACLs) and the specification of a proper formal semantics of ACLs. In this paper, we propose an illocutionary effect-based FIPA-ACL semantics which overcomes the two traditional semantic approaches. The key idea of this new semantics is based on the semantic concepts of success and satisfaction conditions of illocutionary acts in speech act theory, and the common ground theory-based framework. As case studies using this new semantics, we define the primitive speech acts of FIPA-ACL such as inform and request. For the strengths of the proposed approach we illustrate our new semantics on an e-commerce agent purchase negotiation. Also, we compare this approach with two traditional semantic approaches for ACLs.

Proposal for Semantic Digital Archive for UNESCO Intangible Cultural Heritage Sites List: Centering on User-Centric Relational Facet Navigation (유네스코 무형문화유산 시맨틱 디지털 아카이브 구축: 이용자 중심 관계형 패싯 네비게이션을 중심으로)

  • UNESCO clearly has a good user interface compared to other sites. However, it does not have a structure in which user-centric knowledge curating is employed by users. As such, the knowledge structure should be expressed differently in advance for users to enjoy such benefits. At present, almost all current information systems are lacking with semantic and contextual information. Moreover, these systems are deemed insufficient of interlinking various kinds of thoughts in our minds. Thus, it is necessary to model in advance what users are likely to think and provide an interface that they can easily utilize based on that modeling. Furthermore, there is a need for a new structural theory based on semantic technology that can make that possible. Therefore, in this proposal, theoretical and practical insights were presented for user interface implementation to which relational facet navigation based on the structural theory is applied. Moreover, this proposal intends to suggest a "thinking expansion platform" that allows users' ideation of different concepts, including those unfamiliar to them.

A Semantic Analysis of the Indeterminacy in Contemporary Fashion - Focusing on Fashion Since 2000 - (현대 패션에 나타난 불확정성의 의미해석 - 2000년대 이후 패션을 중심으로 -)

  • In a fast changing postmodern society, contemporary fashion is becoming more complicated and ambiguous along with other genres of art than ever before. This phenomenon reigning as a sociocultural paradigm can be defined as 'indeterminacy' and it means 'undecidability'. The purpose of this study is to clarify and analyze the indeterminate characteristics of contemporary fashion reviewing the theoretical background and the architectural formativeness as a comparative research. The core idea of deconstructivism dismantles a causal relationship between function and form in fashion and the conventional notion about clothes. Complexity theory, which is the study of chaotic dynamical systems, suggests the creative idea and concept of infinite possibilities on a formative method. Meanwhile, catastrophe theory of discontinuous change can be used as interpretative strategies for the process of deconstruction and reconstruction. As a result of this study, the indeterminacy of fashion can be analyzed into five semantic categories: irregularity, immateriality, randomness, complexity and changeability. The intrinsic value of the indeterminacy in contemporary fashion is the interaction with a sociocultural ideology and a technological environment as well as an expansion of formative expression. To conclude, it can be said that the indeterminacy in fashion is a new interpretation of the relationship among body and space, clothes and society.
