  • From the definition of the cruise ship mission based on the investigation of the customer needs and statistical estimates and to design of the residence area of the cruise ship, in this study a conceptual design of the traditional ship parts (the lower hull) was carried out. for the light weight estimation of the cruise ship, several methods that have been used for commercial ships were evaluated to adapt for the cruise ship, the main particulars of the ship were determined with the light weight estimation and the assumed dead weight. From these main particulars of the ship, the hull form was developed with CFD verification and the general arrangement for the lower hull was achieved. For several loading conditions the intact stability of ship was checked.

  • This paper describes a requirement architecture modeling for the front end of KT-1 export version requirement definition processes to construct SDS(system development specification). The requirement definition process is a highly conceptual process that is difficult to carry out. This paper focuses on how to perform the KT-1 export version requirements definition process including the integration of process, methods and tools for the front-end activity of requirements definition process. This requirement model is structured in four segments, including requirement layering, requirement categorization, life cycle stakeholder and requirement definition process using Computer-Aided Systems Engineering tool(CORE).

  • In this paper, the 'facility' and its related concepts were analysed, and then ontological conceptual definition for the facility was conducted based on a variety of relationships between those concepts. First, as a facility conception relation, inclusion relation, instance relation, rule relation, attribute relation and part-whole relationships were investigated. Second, facility concepts were prescribed as a physical entity in which many parts were functionally integrated. Third, by strictly separating the basic concept and role concept, reading facility, exhibit facility, etc. were not supposed to make multiple inheritances by putting subordinate concepts as those of role concepts, not those of the concept of facility. Fourth and lastly, an ontology for the facility was made by using OWL DL.

  • In these days, XML is a de facto standard language for representing and exchanging data. In order to define the conceptual model of the XML, we need to define the representation rules expressed in the diagram and propose the transformation algorithm that converts the diagram into a logical model of XML. This paper proposes a transformation methodology for generating a logical model from the conceptual model of the XML. We use CMXML as a conceptual model and generate XML schema definition as a logical model. For this, we define transformation rules and data structures for XML schema, and propose a transformation algorithm.

Conceptual Study on User Experience in HCI: Definition of UX and Introduction of a New Concept of CX (Co-Experience) (사용자 경험에 대한 HCI적 관점에서의 개념적 고찰 사용자 경험의 개념 정의와 공동 경험감 개념의 제안)

  • The concept of UX(User Experience) has been an important issue both in academic and practical areas in recent years. However, the concept had either been lacking an implicit definition or confused with otherrelated concepts in most cases. In this paper, a conceptual definition of UX and the optimal UX in HCI as well as conditions of it is presented based on John Dewey's pragmatism. Also, due to the current shifts in the technological environment in HCI, it is impossible to fully explain the phenomena by using the current concept of UX as users experience technology not only individually but also socially. Therefore, this paper introduces the concept of users' shared experience, co-experience(CX), and its requisites.

  • The purpose of this study is to identify the legal definition and usage of cultural property term related to the architecture within the cultural property-related legal system and general legal system, and to present proper terminology and specific concepts that can be used for the architecture as cultural properties. In the current cultural property legislative system, terms about the architecture are diverse and obscure, and the definition of each term is different from the concept in the general legal system. In this context, this study presented the terminology of 'the architectural heritage' as 'a cultural property by construction act' to cover whole cultural properties related to Korean architecture. And the conceptual scope of the architectural heritage is divided into the technology and the performer related to the act, the record and the building related to the product. and Each concept needs to be specifically tailored to its object and scope. Systematic definition of terms for cultural properties related the architecture can positively influence systematization of cultural property preservation and management as well as empirical research and education on Korean architecture.

On the Two Conceptually Thorny Issues in IT Governance Definition (IT 거버넌스 정의에서 제기되는 두 개의 개념적 난제에 대한 고찰)

  • Two conceptually thorny issues in IT governance definition and understanding are examined and discussed. It is argued that the traditional IT governance definition, which defines governance in terms of the content of enterprise IT activity, is prone to logical inconsistency and indeterminacy. A new objectives-bound definition of IT governance is proposed as a remedy to the problem. It is proposed that the essence of the objectives-bound IT governance lies in making enterprise IT activity explicit, formal and subject to external scrutiny in its effort to achieve the effectiveness, transparency and accountability of IT. A conceptual apparatus called IT activity axes is employed to characterize and distinguish the different approaches to IT governance definition and understanding. It is suggested that IT governance can be defined using a simple frame of reference with logical consistency and coherence. The theoretical and practical implications of the IT governance definition are discussed at the end.

  • The purpose of the study was to investigate the change of students' conceptual structures about sedimentary rocks through the field trip. A semantic network analysis method was utilized to assess the change. An open-ended questionnaire was developed to assess high school students' knowledge of sedimentary rock including its definition, classification, formation process, and characteristics. Fifteen high school students participated in the field trip of this study. The text data were analyzed using the semantic network analysis method. Results are as follows. First, high school students' conceptual structures about sedimentary rocks were more expanded after the field trip. Second, students' conceptual structures formed a 'small world network' by combining the sub-clusters. Third, the size of students' conceptual structures was decreased after a few month of field trip. Nonetheless, the connection among the clusters remained the same.

  • As evidenced through rapidly growing digital repositories and web resources, automatic metadata generation is becoming ever more critical, especially considering the costly and complex operation of manual metadata creation. Also, automatic metadata generation is apt to consistent metadata application. In this sense, metadata quality and interoperability can be enhanced by utilizing a mechanism for automatic metadata generation. In this article, a mechanism of automatic metadata extraction called ExMETA is introduced in order to alleviate issues dealing with inconsistent metadata application and semantic interoperability across ever-growing digital collections. Conceptual graph, one of formal languages that represent the meanings of natural language sentences, is utilized for ExMETA as a mediation mechanism that enhances the metadata quality by disambiguating semantic ambiguities caused by isolation of a metadata element and its corresponding definition from the relevant context. Hence, automatic metadata generation by using ExMETA can be a good way of enhancing metadata quality and semantic interoperability.
