In this paper, we propose a disconnectedness determination algorithm for workflow-supported enterprise social networks. this networks can be discovered from the work-allocation relationships between activities and performers in workflow procedures and It networks are useful to analyze, evaluate and numerically explain the work-performance of performers. But there could be the disconnectedness due to the characteristics of workflow, and therefore analysis result of performers can be inappropriate logically as well as mathematically. So, we have to decide whether or not this network is disconnectedness before we analyze workflow-supported enterprise social networks. Conclusively, we try to carry out a thorough investigation into the formation reasons of the disconnectedness, and propose a determination algorithm of the disconnectedness for workflow-supported enterprise social networks.

오늘날 인터넷을 통한 모든 통신망이 끊임없이 발전하고 있는 가운데 IPv4가 가지는 문제점들이 치명적인 위협으로 대두되고 있다. 따라서, 폭발적인 인터넷 사용자 증가로 인한 IP address의 고갈과 느려져만 가는 인터넷 속도에 대해 대안이 필요하다. IPv4는 32bit 체계로 약 40억 개의 IP 주소를 가지고 있으나, 인터넷 초기의 무분별한 클래스를 사용하여 40억 개보다 적은 양의 주소를 사용 할 수 있게 되었다. IPv6는 128bit의 주소 체계를 가지고 있으며, 3.4 $10^{38}$개의, 천문학적인 주소를 할당 할 수 있으며, 보안성과 서비스 품질보장(QoS), 이동성 기존의 인터넷 속도의 가속 기능 등 다양한 장정들을 가지고 있다. 본 논문에서는 IPv4에서 IPv6로 진화해 가야 하는 시기적인 요소보다는 IPv6로의 공존해 나아가야 하는 기술적인 문제를 극복하기 위해 기존 IPv4망에서 IPv6 주소체계를 지원할 수 있도록 설계하고 Backbone network 구성에 일반적인 구현을 통하여 IGP와 EGP 구간의 라우팅 정보공유에 대하여 논의한다.

Within the article, strategic guidelines for the modernization of microeconomic systems are identified. Modernization levels of the potential implementation are formalized for enterprises: contractile, extensive technical, technological, progressive, adaptive, steady, intensive, creative, absolute and leader modernization. This allowed to specify the directions and tasks of the enterprise modernization at different management levels. Accordingly, the conditions and criteria for selecting resource tools are set. It is proved that the strategies of the potential modernization of enterprises must be carried out at four main management levels: first, at the enterprise level; secondly, for a particular type of product / service; third, by functional directions of modernization of separate spheres of the enterprise activity or responsibility, fourth, at the level of structural units of the enterprise. It is substantiated that in the processes due to the activation of the potential modernization, the resources are transformed into the results of the innovation implementation and the investment strategies modernization. A system of tasks for the corporate strategies implementation in order to modernize microeconomic systems has been formed. Key vectors of the activation determine the nature and properties of investment resources and necessary innovations to enhance the modernization potential. Therefore, the system of innovation and investment strategies' modernization, based on the vector and resource provision of the modernization process, is specified:

The presented research is devoted to determining the role of the mechanism of attracting investment resources in innovative development in the conditions of transformation using the process approach. It is proved that the process approach is dominant for this study because investments are considered as a process of investing in innovative development in the enterprise in the context of digitalization, and its application allows to take into account the impact on the mechanism of attracting investment resources. related to the mechanism of attracting investment resources of the enterprise. It is substantiated that the mechanism of attracting investment resources for innovative development in the context of digitalization is a specific way of organizing, mobilizing and using investment resources for innovative development of the enterprise in the context of digitalization under the influence of economic development laws, government regulation. The effectiveness of attracting investment resources in innovative development is ensured by the mechanism that exists in the enterprise. The mechanism of attraction of investment resources in innovative development in the conditions of digitalization gives the chance to define an optimum ratio between sources and volume of attraction of investments in innovation sphere.

ISPs and Enterprises are equipping their networks with sufficiently high speed facilities and provide large bandwidths members. However the high speed enterprise network does not have satisfying end-to-end network performance within the network in spite of under utilization. The root cause of this performance degradation is a micro-congestion, which is a short-live event of traffic congestion. A micro-congestion causes packet loss, delay and packet reodering, and finally results in end-to-end network performance degradation. In this paper, we propose a micro-congestion detection method and find out the characteristics of performance degradation by analyzing traffic archives which is collected from a network link when a micro-congestion occurs.

In this paper, we propose a secure communication framework for interaction and information sharing between a server and agents in DS-NVSA(Detection System of Network Vulnerability Scan Attacks) proposed in〔1〕. For the scalability and interoperability with other detection systems, we design the proposed IDMEF and IAP that have been drafted by IDWG. We adapt IDMEF and IAP to the proposed framework and provide SKTLS(Symmetric Key based Transport Layer Security Protocol) for the network environment that cannot afford to support public-key infrastructure. Our framework provides the reusability of heterogeneous intrusion detection systems and enables the scope of intrusion detection to be extended. Also it can be used as a framework for ESM(Enterprise Security Management) system.

We need the flexible method for communication network configuration and fault management business procedure. Therefore development of systematic integrating fault management system is essential to meet on these requests. We must design the integrating fault management system so that can run the repair processing for both data communication network management and new next generation data communication network of various type. In general it is effective that the system is consisted of decentralized module to be accessibele for business logic and datum to remote area. To Solve these problem, a method is to use object-oriented design technique. That is, it is to abstract reusability objects and make component module using the abstracted objects. In this paper, we propose a fault management system of communication network service using object-oriented design techniques which are UML(Unified Modeling Language) and EJB(Enterprise Java Bean).
