Thus, all systems and sensors corresponding to navigation are integrated to an INS (Integrated Navigation System) or an IBS (Integrated Bridge System). Propulsion automation systems, propulsion systems, auxiliary systems, and power management systems are integrated to an ICMS (Integrated Control and Monitoring System), an IPMS (Integrated Platform Management System), and IMCS (Integrated Monitoring and Control System). This paper introduces the results of designing and implementing an Integrated Interface System which ties up diverse system interfaces via network and inversely converts network signals into a proper interface signal type connected to other systems.

Today, most of elevators have an emergency call facility for emergency situations. However, if the network installed in the elevator is also out of power, it cannot be used for the elevator remote monitoring and management. So, we develop an integrated and unified emergency call system, which can transmit not only telephone call but also data signals using PSTN(Public Switched Telephone Network) in order to remote monitoring and management of elevators, even though a power outage occurs. The proposed integrated emergency call system to process multiple data such as voice and operational information is a multi-channel board system which is composed of an emergency phone signal processing module and an operational information processing module in the control box of elevator. In addition, the RMS(remote management server) systems based on the Web consist of a dial-up server and a remote monitoring server where manages the elevator's operating information, status records, and operational faults received via the proposed integrated and unified emergency call system in real time. So even if there's a catastrophic emergency, the proposed RMS systems shall ensure and maintain the safety of passengers inside the elevator. Also, remote control of the elevator by this system should be more efficient and secure. In near future, all elevator emergency call system need to support multifunctional capabilities to transmit operational data as well as phone calls for the safety of passengers. In addition, for safer elevators, it is necessary to improve them more efficiently by combining them with high-tech technologies such as the Internet of Things and artificial intelligence.

Application log files contain error messages; operational data and usage information that can help manage applications and servers. Log analysis system is software that read and parse log files, extract and aggregate information in order to generate reports on the application. In currently, the importance of log files of firewalls is growing bigger and bigger for the forensics of cyber crimes and the establishment of security policy. In this paper, we designed and implemented the SILAS(SysLog-based Integrated Log mAanagement System) in distribute network environments. It help to generate reports on the the log fires of firewalls - IP and users, and statistics of application usage.

In NGNs(Next Generation Networks), It is necessary for Integrated management of resource and information to satisfy high-quality users'demands, such as stable speed, guarantee of high level service and service requirement in various fields. In relation to this, technology for efficiently using limited resources is becoming interesting things more and more. Therefore policy of network service is dealt essentially. Recently, DEN(Directory Enabled Network)-based personalization service is user-dependent services in NGNs, and integrated management and efficient use of limited resources. Also, PBNM(Policy-Based Network Management) is new technology defined and applied by policies of communication service environments and users on demand. Subsequently to study on how to optimizing the PBNM is of great importance. In this paper, we propose a technology of the PBNM based on DEN standardized in DMTF(Distributed Management Task Force).

The wide spread of Internet makes susceptible to the attacks via communication Web from hackers using the vulnerability of both computer and network systems. In this paper, we design and implement an integrated security system, named as LISS(Linux-based Integrated Security System) in which an integrated security management is possible. This system is based on the open operating system, Linux and consists of open security tools, which is effective in security management of Linux based-servers. We also construct a test-bed in order to testify the performance of the LISS. It is revealed that the implemented system captures all the attack Patterns generated from Network Mapper.

At an integrated steel mill, various raw material such as coal and iron ore are unloaded from a large ship. The unloaded raw material is then transported to storage yards through a complex belt conveyer network. We propose an optimization model for scheduling the unloading operations under the limitations of available berths, unloading equipments and transportation capacity of the belt conveyer network. We show that the problem is NP-Hard and propose a heuristic approach to the problem.

Network security system used in the large scale network composes individual security system which protects only own domain. Problems of individual security system are not to protect the backbone network and to be hard to cope with in real-time. In this paper we proposed a security system which includes security function at the router, and the access point, which exist at the backbone network, to solve the problems. This security system sends the alert messages to an integrated security management system after detecting intrusions. The integrated security management system releases confrontation plan to each suity system. Thus the systematic and immediate confrontation is possible. We analyzed function verification and efficiency by using the security system and the integrated security management system suggested in this paper. We confirmed this integrated security management system has a possibility of a systematic and immediate confrontation.

This manuscript treats a new paradigm for the Korean health care system. We give an account of innovative health care delivery and payment models widely discussed in the contemporary US accountable care organization and coordinated care organization. In doing so, we explore a new health care model amenable to foreseeable changes to the health care system. We propose creating an integrated health care system in which the network of health care providers delivers coordinated and comprehensive care for enrolled patients residing within the geographic boundaries served by the provider network; providers may participate voluntarily in one or more networks and assume shared responsibility for patient care and cost; provider networks compete with each other based on cost and quality; and consumers are allowed to choose a network. We expect that the new paradigm will create a financially-sustainable system that assures quality of care and improves patient experience, minimizing the existing system-wide inefficiency through cross-network competition and within-network care coordination.

최근 급속한 네트워크 기술의 발달로 이들에 대한 관리의 필요성이 제기되었고 이를 위해 SNMP와 CMIP등과 같은 표준이 등장하여 사용되어 왔다. 그러나 점점 더 다양하고 복잡한 네트워크가 형성되자 이들에 대한 효율적인 관리가 필요하게 되었다. 현재, TMN은 개념에 있어서 보편성 및 가장 일반화된 관리개념이며 최종적으로 도달할 네트워크 관리 개념을 포함하고 있다. CORBA는 분산환경에서 응용프로그램을 쉽게 구현할 수 있는 기반을 제공하고 있다. 따라서 이러한 두 가지 기술을 접목한 CORBA와 TMN을 통합하고자 하는 많은 연구가 진행되고 있다. 본 논문에서는 현재의 CORBA/TMN 통합에 대한 연구를 바탕으로 효율적인 네트워크 통합 관리 구조를 정의하고 TMN의 기능중 Alarm Surveillance를 구조에 맞춰 구현하였다. 구현된 Alarm Surveillance System은 다양한 대리자들로부터 보고되는 여러 형태의 Alarm 정보에 대해, 처리 및 운용자에 대한 보고수행 등을 일관성 있게 처리하고 있는 것을 보여주고 있다. 따라서 제시된 Alarm Surveillance System은 사용자에게 일관성 있는 관리행위를 제공함으로써 다양한 관리구조가 적용된 복잡한 네트워크 관리를 제공할 수 있다. 또한 전체 네트워크로부터 필요한 통계분석을 위한 자료 수집 등의 편의를 제공할 것이다.Abstract Recently, due to the rapid development of network technology, the need for the network management appeared. So two representative standardards, SNMP and CMIP, have been applied to many network management system. But the more complex and vaious network are constructed, the demand for more efficient network management technology grew bigger. Currently, TMN technology is beginning to be widely applied to the management of networks. CORBA has been widely adopted for developing distributed systems in many areas of information technology. CORBA provides the infrastructure for the interoperability of various object-oriented management applications in a distributed environment, and, recently there have been world-wide research for the integration of CORBA within a TMN framework. Many attempts have been made to enable network management using CORBA techonology and some are working on already. This paper defines the architecture for integrated network management based on current CORBA/TMN integration technologies and then presents the design and implementation for alarm surveillance system which was applied to the defined architecture. The prototype implementation was done using IONA orbix. The proposed integrated network management framework will provide users with consistent management operations and ability to manage complex and various networks and to gather statistical data from those networks.

The network-wide performance management is crucial for maintaining the quality of network services, which requires the collection and monitoring the performance data at individual network nodes. Most of the public networks, however, are composed of diverse, heterogeneous network nodes that are managed by various types of proprietary management systems with a conventional operator console and embedded management functions, which makes it difficult to implement the integrated performance management systems. Even though the developments of TMN (Telecommunication Management Network) based management systems are being attempted, the little work has been done in performance management area. In this paper, we propose the performance monitoring architecture for ATM switches using the 0₃ object model and describe how to implement the TMN-based performance prosy agent for ATM switching systems. The proposed performance proxy agent provides the TMN standard performance management interfaces by translating the proprietary performance management functions, which eventually leads to network-wide integrated performance management.
