This study proposes the logical data model design of a spatial data model that complies with international standards for the waterworks of underground facilities. We conduct a preliminary study related to underground spatial data standards and data models, and review the status of the existing systems. Then, we defined the conceptual design direction of underground spatial data model based on the problems and issues. Next, we defined the terminology, classification, semantic relationships of waterworks. Next, for the conceptual design of the underground spatial data model, we defined the naming criteria for all data according to the waterworks classification. In addition, a logical model is drawn and described using UML (Unified Modeling Language) diagrams. Based on the results, it is expected that the accuracy related to underground facilities data will be improved.

공간 정보 추출은 대량의 텍스트 문서에서 자연어로 표현된 공간 관련 개체 및 관계를 추출하는 것으로 질의응답 시스템, 챗봇 시스템, 네비게이션 시스템 등에서 활용될 수 있다. 본 연구는 한국어에 나타나 있는 공간 개체들을 효과적으로 추출하기 위한 앙상블 기법이 적용된 Bidirectional LSTM-CRF 모델을 소개한다. 한국어 공간 정보 말뭉치를 이용하여 실험한 결과, 기존 모델보다 매크로 평균이 향상되어 전반적인 공간 관계 추출에 유용할 것으로 기대한다.

기존의 공간 관계 추출은 관계 속성 추출 후 적합한 개체와의 관계 형성이 불명확한 점과 한 개체가 다중관계에 속할 때 관계 형성이 불확실한 문제가 있다. 이를 해결하기 위하여 본 논문은 최근 개체명 관계 추출에서 사용하는 표 방법을 공간 관계 추출에 적용하였다. 기존 모델과 제안 모델을 비교하기 위하여 상한 성능을 측정하였으며, 그 결과 제안 모델이 더 우수함을 보였다.

In this paper, we propose a multimedia query language MQL which defines and manipulates multimedia data as integration of monomedia data in time and space. The MQL is designed for a multimedia data model, called the object-relationship model, and based on the multimedia object calculus which formally describes operations on multimedia data. The SQL- like syntax for class definition and object manipulation, such as retrieval, insert, update, and delete, is defined. We show how the MQL can represent the user queries using composite temporal-spatial class structures and various relationships, such as equivalence and sequence.

The modes of narratives and communication have expanded due to social and cultural changes and technological development. Thus texts have become multimodal and media hybridities and media crossover have been increasing as well. Multimodality requires new literacy to understand and interpret those multimodal texts other than existing traditional literacy approaches. The New London Group (2000) argues that multiliteracies are needed to serve today's changing multimodal texts. Kress (2003) also argues, visual texts have been prevailing, being mingled with other modes of texts such as linguistic, audio, gestural, and spatial modes. Literary texts are not exception in this trend of multimodality. The recent renaissance of comics, in particular, the new light on graphic novels can be interpreted in this historical vein. In comparison to comics, no consensus has been made in defining graphic novels, however, many studies have been recently conducted in order to look into the potential of graphic novels in building multiliteracies. In this paper, the graphic novel as a literary genre are explored from a histocial perspective and the definition of graphic novels was attempted to be made. In the light of multiliteracies, this paper presented cases that show how graphic novels can be utilized to build multiliteracies. Lastly, the use of graphic novels for English as a foreign language was introduced as well. The author hopes that at the age of multimodality, the potential graphic novels have in language and literacy education can be taken into account by language teachers and students in expanding their territory of literacy.

본 논문에서는 GUI(Graphical User Interface)를 사용하여 사용자가 상호 작용적으로 도형 언어(visual language)의 문법을 기술함으로서 자동으로 공간 파서를 생성하는 공간 파서 생성기 SPG(Spatial falser Generator)의 구현에 대하여 논한다. 본 시스템의 장점은 다음과 같다. (1) 사용자가 도형 언어의 문법을 정의하고 실제로 파싱하고 싶은 도형 언어를 입력하는데 사용되는 도형 에디터를 가지고 있다. (2) 사용자가 도형을 이용하여 대략적인 문법을 자동으로 생성한 뒤, 수정하여 최종적인 문법을 정의하도록 한다. (3) 제약 해소기(Constraint solver)를 가지고 있어서 파싱된 도형 언어들이 그 생성 규칙에 쓰여져 있는 제약을 유지한다.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, a standard specification was required for compatibility and interoperability in various RTLS(Real-Time Locating Systems) according to the development of RTLS to provide location and status information of moving objects using the RFID Tag. For these reasons, the ISO/IEC published the RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and im plemented RTLS based on the spatial DSMS(Data Stream Management Stream) for efficiently managing and searching the incoming data stream of moving objects. The spatial DSMS is an extended system of STREAM(STanford stREam datA Manager) developed by Standford University to make various spatial operations possible. RTLS based on the spatial DSMS uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatial DSMS. Finally, we proved the efficiency of RTLS based on the spatial DSMS by applying it for the staff location management service.

"The "Map Algebra", beeing recognized as a viable theoretical framework for GIS (Geographica Infonnation System), models map layers as "operands" which are the basic unit of geo-processing, and a variety of GIS commands as "operators." In this paper, we attempt at lifting some limitations of map algebras proposed in GIS literature. First, we model map layer as "function" such that we may employ the notion of meta operator (or, higher-order funtion) available in the functional programming paradigm. This approach provides map algebraic language with "programmability" needed in GIS user language. Second, we extend the semantics of, and improve on the sytactic structure of map algebraic language. Mer the data model and language associated with map algebra are formalized, we proceed to design and implement a prototype of map algebraic processor. The parser of the language in our prototype plays the role of transforming the native and heterogeneous user language of current GISs into a canonical map algebraic language. The prototype, named "MapSee" is a proof-of-concept system for the ideas we propsed in this paper. We believe that the uniform interface based on the map algebraic language will make promising infrastructure to support "Internet GIS." This is because the uniform but powerful interface through the Web clients allow access to both geo-data and geo-processing resources distributed over the network.to both geo-data and geo-processing resources distributed over the network.

Currently with development of development and the hardware of the superhigh speed network about increase is spreading out at the rapid pace the many multimedia contents quite from internet. The production environment is growing about the multimedia contents because of such as circumstance, as well as multimedia contents will increase. However, Numerous voice, the picture, with text etc. the time of the same multimedia contents and problem of spatial synchronization occur, started. W3C(World Wide Web Consortium) solves like this problem point presented the method for. Does so, SMIL(Synchronized Multimedia Integration Language) where puts a base in XML(Extensible Markup Language) will be able to compose the expression of the multimedia contents which is various standard was proposed. SMIL the individual multimedia object of chain with time will be able to integrate with the multimedia presentation which is synchronized spatial in order. In this paper a variety of multimedia content and synchronization of the time and space, to be represented by integrating the design and implementation of SMIL authoring system.
