최근 네트워크 구조 및 시스템은 다양한 서비스의 시기 적절한 적용을 위해 개방형구조의 모습을 지향하고 있다. 개방형 네트워크 구조는 제3의 서비스 개발자들의 시장 참여를 유도하고 경쟁을 유발시켜 서비스 품질을 개선하고 시스템을 효율적으로 유지, 관리 할 수 있도록 만들어 준다. Mobile IP가 단말의 macro mobility를 지원하기 위한 프로토콜의 특성상 단말이 이동할 때 발생하는 등록 절차에 따른 지연으로 인한 패킷 손실에 대한 문제점을 안고 있다. 이러한 문제점은 향후 이동 망에서 늘어나는 실시간 데이터 전송 품질을 저하시킨다. 핸드오프 지연을 해결하기 위해 여러 가지 방법들이 제안되어 왔으며 표준화되고 있다. 본 논문에서는 개방형 네트워크 모델에서 micro mobility를 지원하기 위한 방법을 제시하고 각 이동 망을 구성하는 서브 시스템의 역할 및 특징에 대해 설명한다.

현재 통신 시장의 패러다임이 음성 서비스 위주에서 IP 기반의 데이터 서비스 중심으로 변화하고, 개방화된 유무선 인터넷 서비스를 제공하려고 함에 따라 이동 통신망과 인터넷 망을 연동하는 개방형 유무선 게이트웨이는 필수적인 사항이 되었다. 이를 위해서 UMTS 이동 통신 시스템에서는 GGSN 이라는 개방형 유무선망 연동 게이트웨이를 제공하고 있다. UMTS 이동 통신 망에서는 무선 인터페이스를 통해 전달되는 IP 패킷을 위한 GPRS 망을 정의하고 있다. UMTS GPRS 망은 패킷 스위치 기능을 하는 SGSN 과 무선망과 인터넷망간에 연동을 위한 GGSN 을 중심 축으로 하여 구성되어 있으며, 이들간은 GTP 프로토콜를 이용하여 통신을 한다. 본 논문에서는 개방형 유무선 연동 게이트웨이인 GGSN 기능 구현을 위한 프래임웍 설계 및 구현에 관한 논문이다.

In the era of big data, analyzing not only structured data but also unstructured data is emerging as an important task. Official documents produced by government agencies are also subject to big data analysis as large text-based unstructured data. From the perspective of internal work efficiency, knowledge management, records management, etc, it is necessary to analyze big data of public documents to derive useful implications. However, since many of the public documents currently held by public institutions are not in open format, a pre-processing process of extracting text from a bitstream is required for big data analysis. In addition, since contextual metadata is not sufficiently stored in the document file, separate efforts to secure metadata are required for high-quality analysis. In conclusion, the current official documents have a low level of machine readability, so big data analysis becomes expensive.

This study aims to use Wikidata to increase access to archival resources and see ways to share and reuse constructed data. To this end, the status of digital archives locally and abroad was identified using the description standard of archival resources in the digital environment discussed in the archival science field and the research related to data management and sharing of digital archives. The structure and characteristics of Wikidata were identified, and cases of digital archives applying Wikidata were investigated. The case analysis suggested implications for data sharing and reuse as well as the considerations for applying Wikidata to digital archives. The results of this study can be used as preliminary data for developing services using Wikidata in the actual archive field by understanding the recent trends in data open and sharing related technologies in constructing digital archives.

Recently many of earlier GIS services are changing to the form of user-participated dynamic geoweb service like many new impressive web 2.0 services substitute for earlier old-fashioned web 1.0 services. Many relevant technologies are necessary to be developed so as to integrate a number of geospatial data and functions all around into the useful geoweb services. It is also necessary to make the integration easy and to cope with the rapid changes in geoweb environment. In this study, the trend of relevant geoweb technologies were reviewed before, and the development of open geospatial service platform were carried out. As a result, open 2D/3D map service engine, user-participated mashup engine, Open API search engine and so on were im plemented as the core components of that platform. The platform will be able to be used as the common platform among a number of applications in the fields such as public/private GIS integration, u-city projects and GIS/LBS services etc.

Recently, various bioinformation technologies have been proposed, and research and development on the collection and analysis of the human body related bioinformation have been continuously conducted to support the human life environment and healthcare. These biomedical research and development processes add to the redundancy and complexity of the R&D elements and put a heavy burden on the follow-up research developers. Therefore, this study utilizes an open bioinformation platform that effectively supports the collection and analysis of bioinformation to improve the redundancy and complexity of bioinformatics R&D based on the bioinformatics platform. In addition, I propose an open interface that supports acquisition, processing, analysis, and application of bio-signals. In particular, we propose a biometric information normalization pattern model through data analysis modeling of brain wave information based on an open interface.

In accordance with the completion of the spatial database building works in the central and/or local government authorities as well as the rapid popularization of various information services through internet, it is heavily required to provide spatial information services through World Wide Web. To provide a qualified spatial information service, it is crucial to have a Web-based GIS (Geographic Information Service) service system equipped with the publicity, the convenient accessibility, and the easy-to-use user interface. In this paper, we introduce a new component system for Web-based spatial information services based on the OpenGIS Simple Feature specification for OLE/COM[3] and OLE DB specification[4]. The important functionality of a Web-based spatial information service system includes its accessibility of various existing GIS server system and huge databases in addition to the resolution of response-time delay problems caused by transmitting a large amount of digital maps via internet[6]. To cope with these problems, our component system has been designed to access heterogeneous databases in transparent manner and to support vector-based and/or image-based image production techniques for shortening transmission time.

Recently, the South Korean government actively opens the public data to encourage people to use it in private sector. It is based on 'Government 3.0' that is the paradigm for government operation. According to this trend, a data platform is required for establishing and commercializing business models that utilizing geospatial data. However, it is currently insufficient to establish the geospatial data system using the text-based public open data. This study constructs a geospatial data supply system using the public data for the purpose of providing and using the public data of spatial reference type efficiently. It improves the accessibility of user and the usability to the public data having location information. Besides, this study suggests that the components of the appliance system that connects the public data from different public institutions for different purposes with producing the geospatial data in the type of a finished product.
