XML은 웹에서 데이터 교환을 위한 마크업 언어로 반-구조화된 정보나 구조화된 정보를 교환하고 저장할 수 있으며, 표준언어로 채택되어 가고 있고, 강력한 표현력을 가지고 있기 때문에 다양한 애플리케이션을 가능하게 한다. 문서와 객체가 구조화 될 수 있는 방법을 제공하는 XML은 계층적 구조로 이루어진다. ORDB에서는 스키마 객체들이 계층적 구조로 구성되어 하나의 큰 객체를 이룬다. XML과 ORDB 사이에 단순한 XML 문서는 직접 변환이 가능하나 복잡한 XML 문서를 다룰 때는 객체 기반 변환 방법으로 처리되어야 한다. 따라서 본 논문에서는 XML DTD를 객체로 변환하고 변환된 객체를 ORDB 스키마로 변환하는 방법에 대하여 연구하였다.

인터넷 사용자들의 증가와 함께 네트워크에서 데이터 교환량이 증가하고 있다. 따라서 네트워크 트래픽과 서버의 부담으로 인하여 WWW 서버로부터 응답 시간의 하락은 많은 문제로 제기되고 있다. 본 논문에서는 WWW cache 서버를 이용하여 응답시간을 줄수 있는 방안을 제시한다. 이런 목적을 위하여 www cache 서버를 원격으로 교체할 수 있는 알고리즘을 제안한다.

SNS is a platformwhere users build a social relationship and share opinions and informations. To do these, it supports a text, an image and a video data. As it is possible to exploit the location data of a smart device, SNS tries to use the location data. However,since SNS does not support the coordinate data, it provides the restricted function sharing the image map instead of the vector map. In this paper, we propose a chatting systemsharing pathsto support the coordinate data on a classical SNS. On the proposed system, it is possible for usersjoined in a roomto watch a vector map of same area and exchange texts. If a user builds a path on the map, the system propagates the coordinate data of the generated path and the other users joined in the room watch the path immediately. The implemented chatting systemhasthe benefit to share the information related a map between users using coordinate data.

국내에서는 수량산출정보의 전자적인 교환, 납품 등의 활용을 위한 자료구조 및 파일포맷 등을 규격화 하여 디지털 수량산출정보 교환표준을 개발하였다. 국외에서는 IFC 국제표준을 통해 BIM 발주시 데이터 납품 포맷으로 IFC를 활용하고 있으며 건축분야를 중심으로 공사비 정보의 표준 개발이 이루어 지고 있다. 이에 본 논문에서는 디지털 수량산출정보 교환표준의 Type 및 Element와 IFC 국제표준의 공사비 정보 Entity를 비교분석하여 국내 토목분야 실정에 부합하는 공사비 분야 정보모델 표준개발의 기반자료로 활용하고자 한다.

As the medical environment field has been facilitated by the rapid development of the information technologies and ubiquitous healthcare service based on network, the exchange of medical information between hospitals become more and more important. However, although most electrocardiograph vendors have provided digital modalities and their ECG data management systems, these were proprietary and not compatible with each other due to multiplicity of vendor specific formats and lack of open ECG data standards. Therefore, we aim to design and develop the ECG management system for archiving, saving, searching, viewing and transferring ECG data and the diagnostic reports. And the system is based on Clinical Document Architecture (CDA) developed by HL7 and DICOM Waveform Standard for the exchange of the structured diagnostic reports and the transfer of ECG data.

As the networks proliferate all over the world and the application of the geographical information increase recently, the importance of effective access and exchange of GIS data is recognized. However, existing GIS data are generated by many different organizations without proper standard methodologies and data exchange facilities such as clearing houses are being operated on different DBMS with their own schemata. It makes difficult for users to access and utilize the GIS data even the data are open to public. In this research, we provide the users a search system that interfaces heterogeneous repository systems. In order to interact heterogeneous DBMS we utilize the metadata interchange standard (XMI) from OMG.

응용프로그램에서 담당하던 데이터 교환을 대행하는 통신 미들웨어에 대한 연구가 진행되고 있다. 다양한 디바이스들이 동적으로 네트워크 도메인을 형성하고 동일한 타입의 데이터를 빈번히 주고받는 통신환경에서는 데이터 중심 발간/구독 방식의 데이터 교환이 유리하며 OMG의 DDS(Data Distribution Service) 표준규격에서 이러한 방식을 하였다. 본 연구에서는 OMG의 DDS 표준 규격을 준수하고 시스템 관리 자동화가 가능한 데이터 분배 서비스 시스템인 ReTiCoM을 설계하였다.

A construction process involves many designers, engineers, contractors, consulting engineers and government officials. Thus, it is essential to promote collaboration among such participants through of effective document exchange. There have been efforts to Improve efficiency of document exchange through Web. Also XML/EDI is recommended by its method. So the purpose of the research was to establish the data model for document information management in document exchange for construction participants using web-based XML/EDI. This research proposed a method of modeling document information for systemic management of document information that exchanged by XML/EDI in central and explained concept of application document information that stored in database. This research classified construction document according to its information relation.

The proliferation of using social media and social networking services affects the lifestyles of people. These phenomena are useful to companies that wish to promote and advertise new products or services through these social media; these social media venues also come with large amounts of user data. However, studies that analyze the data of social media within the perspective of information exchanges are hard to find. Much of the previous research in this area is focused on measuring the performance of exhibitions using general statistical approaches and piecemeal measures. Therefore, in this study, we want to analyze the characteristics of information exchanges in social media by using Twitter data sets, which are relating to the Mobile World Congress (MWC). Using this methodology provides exhibition organizers and exhibitors to objectively estimate the effect of social media, and establish strategies with social media use. Through a user network analysis, we additionally found that social attributes are as important as the popular attribute regarding the sustainability of information exchanges. Consequently, this research provides a network analysis using the data derived from the use of social media to communicate information regarding the MWC exhibition, and reveals the significance of social attributes such as the degree and the betweenness centrality regarding the sustainability of information exchanges.
