  • Conceptual modeling is well suited as a subject that constitutes the "core" of the Information Systems (IS) discipline and has grown in response to IS development. Several modeling grammars and methods have been studied extensively in the IS discipline. Previous studies, however, present deficiencies in research methods and even put forward contradictory results about the ternary relationship in conceptual modeling. For instance, some studies contend that the semantics of a binary relationship are better for novices, but others argue that a ternary relationship is better than three binary relationships when the association among three entity types clearly exists. The objective of this research is to acquire complete and accurate understanding of the ternary relationship, specifically to understand practitioners' modeling performance when utilizing either a ternary or binary relationship. To the best of our knowledge, no previous work clearly compares real-world modeler performance differences between binary and ternary representations. By investigating practitioners' understanding of ternary relationship and identifying practitioners' cognition, this research can broaden the perspective on conceptual modeling.

  • XML은 다양한 언어들을 이용하여 문서의 구조나 형식을 논리적으로 정의하고 있지만, 각각의 언어들은 서로 다른 구조와 문법을 채택하고 있어 실세계의 데이터의 의미나 데이터 사이의 관계를 표현하는 개념적 모델의 도구로 사용하기 어렵다. 본 논문은 XML 스키마 문서를 개념적으로 모델링할 수 있는 기법인 CMXML을 제안한다. CMXML은 XML을 형식으로(formal)으로 정의하고, 형식에 의해 각 요소들을 그래픽으로 표현하는 방법을 제시하고, 본 모델의 타당성을 보여주기 위해 CMXML으로 모델링한 개념적 모델을 논리적 모델인 XML 스키마로 매핑하는 기법을 제시한다.

  • This paper tries to extend the conventional conceptual framework of the Internet of Things (IoT) so as to reify an advanced pervasive IoT-community collaboration concept, which is called the process-aware Internet of Things. The extended conceptual framework is embodied as a referential architecture that can be a standardized reference model supporting the conceptual integration of the Internet of Things and the process awareness. The extended referential architecture covers the full range of the architectural details from abstracting the process-aware behavioral semantics to reifying the IoT-process enactments. These extended framework and architecture ought to be the theoretical basis for implementing a process-aware IoT-community computing system supporting process-aware collaborations of Things in pervasive computing environments. In particular, we do point up that the proposed framework of the process-aware Internet of Things is revised from the Internet of Things framework announced in ITU-T SG133 Y.2060 [26] by integrating the novel concept of process awareness. We strongly believe that the extended conceptual framework and its referential architecture are able to deliver the novel and meaningful insight as a standardized platform for describing and achieving the goals of IoT-communities and societies.

  • XML은 문서의 표현 및 교환을 위한 사실상의 표준으로 자리 잡아 왔으며, 논리적 데이터 모델로 널리 사용되어 왔다. XML을 논리적 모델로 사용하기 위해서는 XML이 갖는 의미론에 대한 개념적 모델이 필요하다. 하지만, XML의 고유한 특성을 표현하기 위해 기존의 개념적 모델인 개체관계 모델이나 UML 등을 이용하여 모델을 확장하여 사용해 왔지만 현재까지 표준화된 모델은 없다. 본 논문은 데이터베이스 분야 관점에서 개체 관계 모델을 확장하여 XML의 개념적 모델로 사용하는 대표적인 모델들의 특징을 비교한다. 이를 위해 XML의 개념적 모델이 충족해야 할 요구사항들을 제시하고, 이를 근거로 각 모델들의 접근방식을 비교한다.

  • Since metaphor was proposed to be a matter of thought instead of language over two decades ago, the research in this area has made most of its progress by the cognitivists. For the cognitivists represented by Lakoff, metaphor is not a mere poetic or rhetoric device, but is central to our everyday language. Furthermore, according to them, we categorize the world and break it into concepts mainly through metaphors, and truth conditions simply cannot account for metaphor. However, this cognitivists' view has been severely counterattacked by the truth-conditional semanticists. Their main criticism is that the cognitivists do not provide a way to go from our internal representations to the outside world. It is also criticized that the cognitive theory of metaphor as cross-conceptual domain mappings is too broad and general, and that they do not explain why a particular metaphorical expression should be subsumed under one mapping rather than another mapping, i.e., their schemes and structural relations are not predictive. In this context, the purpose of this paper is to propose a model for metaphor interpretation that combines the virtues of the two opposite views of metaphor. Truth-conditional semantics cannot ignore cognitive aspects of language, so-called states of affairs or mental representations, while cognitive theories cannot neglect vigorous representation of meaning with objective reality. This paper will try to present a preliminary outline of this combining model.

  • This study explored the background of contemporary furniture design called New Design furniture, which newly expresses the aesthetics of communication in the postmodern era. Qualitative conceptual analysis as the principle methodology was used to explore the background of the decorative and meaningful contemporary furniture in postmodernism. Thereby, the postmodern concepts of Charles Jencks, Robert Venturi, and Michael Graves were analyzed in terms of their postmodern architecture and furniture. As initiatives of postmodern architecture and furniture, Jencks, Venturi, and Graves explored the pluralism and eclecticism, the decoration, the semantics, and the materials reestablished from the traditions of craft. As a result, their furniture was expressed by various wood and color; the furniture was beautiful, decorative, pluralistic, and eclectic for communicating symbol, metaphor, narrative, and/or humor with people; the furniture has influenced the communicative elements on the contemporary furniture design called New Design furniture design, which shows the blurring of fine arts and craft distinctions.

  • This paper deals with the polysemous phenomenon of perception verbs in terms of metaphor and metonymy and suggest a model of cognitive semantic structure for them. English perception verbs are often used for representing a mental, cognitive activity as well as representing a physical, perceptive activity. This paper looks for a basis for the polysemous use in the creative system of metaphor and metonymy, especially in the meaning extension function of mind-as-body metaphor. English perception verbs show a good example of a metaphor of domain transfer from physical domain to mental or cognitive domain. This paper suggests the conceptual chain and the semantic structure for the perception verb to show the possibility of polysemy and contextual modulation.

  • Synonym means that the conceptual meaning of the word is the same or similar while other meanings or function of language difference may exist. That is two or more identified names correspond with one sense and have the words with minor difference. Words with synonym relation are a set of same meaning but conceptual area or emotional color, language function can be identified. Therefore, the core research of synonym is the difference analysis and in general difference analysis is progress in the three aspects of Meaning, Pragmatic, and Semantic. However, the difference analysis is the most important. In this paper, the set of meaning item of synonym word 'Attack' is 'zheng', 'fa', 'tao', 'qin', 'xi'. We compare the meaning of five verbs and analyze the difference and characteristics.

  • Aesthetics of use for modern people can be regarded as being weighted toward universal and rational function since it has focused on an 'automation and efficiency' and 'smartness' in terms of technological and human engineering position. Thus, aesthetics of use as an individual agent has remained in minimal level. This study attempts to seek conceptual model of design regarding the behavior of users from the systematization of critical theories about the usability. To do that, 'HERTZAIN TALES' written by Anthony Dune and the concept and system of Droog Design have been used as a core standard. In line with the various experiments by artist groups such as Fluxus, Memphis group and the work of product semantics, and inherent characteristics of Droog design, which has surfaced from the 1990s, concepts that has mentioned in the Hertzain tales have been organized into main texts. By overcoming cognitive bias inherent in the material culture and by overcoming an existing usability based on immateriality and dialectic solution, the autonomy of critical design and instrumentality of Droog design have been systemized. By interpreting the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use From the interpretation of the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use has established the autonomy and independence of the behavior of users, created functional articulation of materials and secured new conceptual model and thus, could be an effective methodical clue for creating an emergent design.
