Inter-operability between heterogeneous radio access technologies (RATs), in the sense of seamless vertical han-dover (VHO) support with common radio resource management (CRRM) functionalities, has recently attracted a significant research attention and has become a prominent issue in standardization fora. In this paper, we formulate the problem of load balancing between cooperative RAT's as a mathematical program and by trading off a pre-defined delay tolerance per request we propose a vertical handover batch processing (VHBP) scheme. To quantify the performance of the proposed VHBP scheme we compare it with a baseline processing scheme, where each VHO request is processed independently under a number of different network scenarios. Numerical investigations reveal significant net benefits of the proposed scheme compared with the baseline, both in terms of achieved load balancing levels but also with regard to the acceptance rate of the VHO requests.

The standardization of NGIS emerges as an important subject because of the needs for sharing information and assuring of information inter-operability. The standardization could be developed by refering OSE/RM, which is promoted internationally, that the corresponding national standards are required. The standardization of NGIS, that has been promoting, consists of standardization of national electronic base-map and common data exchange format. The process for standardization of base-map has been taken in the area of feature-attribute code and data modeling. In the area of common data exchange format, we have been accepted the accommodation of international standards as the national standard.

According to Korean railway safety law and its ordinances, the Korean railway standard(KRS)s to recommend railway operators and manufacturers the regulations for safety and inter-operability of railway system were enacted in the early 2006. In order to reflect rapidly advancing railway technologies and correspond to the international railway standard led by Europe and Japan, KRSs should be confirmed and revised continuously. This paper deals with recent trends in enacting international standards by IEC and the Europe and Japan's activities for this, and presents advancement directions for KRS.

웹 지리정보시스템은 사용하기 쉬운 사용자 인터페이스를 제공함으로써 사용자들로 하여금 공간 데이터의 접근과 분석기능을 쉽게 제공한다. 그러나 이들 시스템들은 독자적인 지리 데이터로의 접근만을 허용하고 분산되어 있는 지리 데이터로 접근할 수 없다. 이는 지리 데이터의 구조와 액세스 방법 등이 서로 상이하기 때문이다. 본 논문에서는 OLE DB을 기반으로 한 분산 지리 데이터의 상호운영성에 대한 기술한다. 또한 분산 지리데이터 서버에서 전달된 데이터는 웬 기반 환경에서 효율적으로 사용되기 위하여 XML 기반의 GML로 변환되어 진다. GML 은 지리정보시스템을 위한 XML기반의 웹 언어로 본문에서는 이를 기술한다. 본 시스템은 컴포넌트 형태로 제공함으로써 구축 비용 및 다양한 사양한 요구사항을 효율적으로 충족시킬 수 있다.

MPV(MultiPhoto/Video)는 디지털 기기 간의 상호-연동성(Inter-operability)를 향상시키고, 사용자의 컨텐츠 관리를 용이하게 하기 위해서 제안되고 있는 표준안이다. MPV에서는 사용자의 편의를 위해서 데이터 부분에 해당하는 컨텐츠를 직접 관리하지 않고 XML 포맷으로 형성되는 메타데이터(Metadata)를 통하여 관리를 하게 되는데, MPV 와 관계 없는 소프트웨어에 의해서 컨텐츠의 정보가 변경되면, 이를 바로 잡을 수 있도록 복구 알고리즘을 제안하고 있다. 하지만. 제안된 알고리즘은 속도가 매우 느리다는 단점을 가지고 있어, 본 논문에서 이의 속도 및 효율를 향상시킬 수 있는 두 가지 알고리즘을 제안한다.

To solve the problem of low inter-operability of systems and low reusability caused by not being standardized and common-shared development foundation between software developers, the government has proposed e-Government(eGov) standard framework. However, the development method based on eGov standard framework is not easy to learn and to use fluently, because it is so dissimilar the existing traditional development method. In this paper, we propose an approach for developing web applications by reusing common components of eGov standard framework, and describe about the case study of developing Can_Pro(Computer Aided Nutritional analysis program for Professionals) based on eGov standard framework. Consequently, we show improvement in productivity and reduction budget through reusability of common components and eGov standard framework.

Defense software has short of interoperability due to the vertical development method which is dependent heavily on application area and development environments. In order to prevent from lack of reusability and operability in application domain software development technology needs component concept and makes shift to the trend of domestic software component industry. This paper covers the research topics such as domain analysis and component architecture to improve and extend reusability and inter-operability for defense information system by two approaches, i.e. CBW (Command Based Work flow) analysis and UML components identification.

In Korea, a single emergency number, such as 911 of the USA and 999 of the UK, does not exist. This issue became highly controversial, when the Sewol Ferry Sinking disaster occurred last year. So, the Korean government has planned to adopt a single emergency number, integrating 112 of the Police, 119 of the Fire and Ambulance, 122 of the Korean Coast Guard, and many other emergency numbers. However, the integration plan recently proposed by the Ministry of Public Safety Security seems to be, what is called, a "partial integration model" which repeals the 122 number, but still maintains 112, 119, and 110 respectively. In this context, the study looks into USA's (diverse) 911 operating system, and subsequently tries to draw general features or characteristics. Further, the research attempts to derive policy implication from the general features. If the proposed partial integration model reflects the policy implications, the model can virtually operate like the 911 system -i.e. a single emergency number system - creating inter-operability between responding agencies such as police, fire, and ambulance, even though it is not a perfect integration model. The features drawn are (1) integration of emergency call-taking, (2) functional separation of call-taking and dispatching, (3) integration of physical facilities for call-taking and dispatching, and (4) professional call-takers and dispatchers. Moreover, the policy implications derived from the characteristics are (1) a user-friendly system - fast but accurate responses, (2) integrated responses to accidents, (3) professional call-taking and dispatching & objective and comprehensive risk assessment, and finally (4) active organizational learning in emergency call centers. Considering the policy implications, the following suggestions need to be applied to the current proposed plan: 1. Emergency services' systems should be tightly linked and connected in a systemic way so that they can communicate and exchange intelligence with one another. 2. Public safety answering points (call centers) of each emergency service should share their education and training modules, manuals, etc. Common training and manuals are also needed for inter-operability. 3. Personal management to enable-long term service in public safety answering points (call centers) should be established as one of the ways to promote professionalism.

The Civil Contingencies Act 2004 in the United Kingdom provides a comprehensive definition of "Emergency", calling upon the Uk's emergency management to deal with any disaster risk regardless of cause or source. Old contingency plans for civil defense and peacetime emergencies have been integrated into current integrated emergency management. In the UK, emergencies are managed by emergency services and other responders at the local level without direct involvement of central government. On top of this, a classified assessment of the risks of civil emergencies is also conducted on a regular basis, not only at the local level but also at the national level. This research looks into the Uk's emergency management system, including recent changes, and its risk assessment systems. Finally, the research draws policy implications for the development of Korea's disaster management mechanism as follows: 1) Korea should adopt an integrated emergency management system and combine civil defense with peacetime emergency planning, 2) it should create inter-operability between emergency responding organizations such as police, fire and ambulance, and finally 3) it must develop risk evaluating tools, such as a Community Risk Register and National Risk Register, both at the local and the national level. Last but not least, the UK emergency management system cannot be directly lifted from the UK and applied to risks and hazards faced by South Korea. Therefore, cross-cultural synthesis of many national approaches to emergency management is further required particularly for customizing policy to the particular needs of Korea.
