Principles of electrical network configuration management and task for their implementation

This paper addresses the management of photonic networks. It presents the first achievements of the ACTS-MEPHISTO project. The project's general objective is to extend the principles of network management (TMN) to generic all-optical networks, in which wavelength division multiplexing (WDM) will be implemented far transmission and routing. This includes the development of information models for optical networks and network elements, of management applications and test platforms to demonstrate fault, configuration and performance management of optical networks, and the promotion of the developed models within ACTS and standardisation bodies. The functional architecture and early information models for the management of optical networks and network elements are described.

Despite medical advances, heart failure (HF) remains a global health problem and sub-Saharan Africa (SSA) is no exception, with decompensated HF being the most common primary diagnosis for patients admitted to hospital with heart disease. In SSA the in-hospital mortality rate of decompensated HF is up to 8.3%. HF is a clinical syndrome that is caused by a diverse group of aetiologies, each requiring unique management strategies, highlighting the need for diagnostic certainty and a broad understanding of the complex pathophysiology of this condition. While there are a number of advanced medical, device and surgical interventions being tailored for HF internationally, the fundamental basic principles of HF management, such as patient education, effective management of congestion and initiation of disease-modifying medical therapies, remain a challenge on our continent. This review addresses both the epidemiology of HF in SSA and principles of management that focus specifically on symptom relief, prevention of hospitalisation and improving survival in this population.

Over the last years the complexity of mobile communication networks has significantly increased. Therefore, Self-Organizing Network (SON) features have been introduced to automate the process of fault-remedying, configuring Network Elements (NEs), and optimizing their operation. Such features are typically implemented by SON functions which actively perform changes to Configuration Management (CM) parameters in order to achieve certain objectives. However, having such features also requires a mechanism that allows us to verify their actions. In case certain NEs experience an undesired behavior, we have to be able to determine whether it is caused by CM changes and, if so, identify the responsible ones for that to happen. In this paper we propose a novel CM change performance assessment method with dynamic scope management for automated CM undo decision making. Our method includes two key properties: the ability to determine the minimal set of cells that are possibly influenced by a certain CM change, and generate a recommendation to accept or reject it based on the observed network performance. Results from our real data evaluation show our method is able to detect anomalous network behavior and identify the responsible changes.

This study was conducted using the library method, where the author collects various materials such as books and scientific articles, which are further elaborated to obtain a broader and deeper understanding of the use of websites in school management. The results of the study show that: first, it is a very complex device because it combines various domains through the internet network, resulting in complex data in the form of text, images, video, audio, and animation. Second, a good school website must meet the following criteria: easy, navigation structure, graphic design, content, compatible, fast, functional, accessible to everyone, and interactive. Third, the school website is an important tool in school management, not only internally but also externally. Fourth, the impact of IT advances has reached various areas of life, so schools should have web-based information systems. Fifth, the school web must be developed in the school's main business domain, namely education and learning. Sixth, to ensure the occurrence of web-based school management, the basic principles of school web management must be carried out properly. Keywords: School Management, ICT, Website, Quality

This study was conducted to find out how to manage Guest Service Attendant services during the covid-19 pandemic. This study uses data collection techniques by conducting interviews and documentation related to the research topic. The data analysis technique used is descriptive qualitative by describing the results of interviews from the Guest Service Supervisor at The Ritz Carlton Hotel Bali. Based on the results of the interview analysis, the management of the Guest Service Attendant at The Ritz Carlton Bali Hotel still needs to be improved. This can be seen from the 4 basic principles of management that there are only 2 points that are carried out maximally while the 2 points are less than optimal and need to be improved again. For this reason, it is expected that the Guest Service Supervisor can further improve teamwork in working so that all basic principles in management can be carried out to the maximum.

Envenoming is one of major health threat especially in developing countries. Basic principles in management of the patient are prompt and accurate identification; addressing immediate life-threatening condition, assess airway, breathing and circulation and support as indicated with emphasis on prioritizing management of impaired cardiac and or respiratory function. Identification of injury should able to address the possibility of envenoming and whether anti-venom is available. First aid management is crucial in preventing venom spread and the next step in hospital emergency room. Anti-venom available for selective envenoming and region should be introduced in significant signs present. Preventive measures from envenoming should be incorporated in travel medicine consultation.

The principles of change and configuration management are foundational pillars for the operational excellence of any industrial enterprise, impacting every facet of its processes, technology, and personnel. They provide a method for identifying, analyzing, preparing, implementing, validating, and documenting engineering changes throughout a product’s lifecycle, ensuring everyone in the organization works from the same product record and changes are communicated in real-time. Change and configuration management are core enablers of the digital thread. However, the challenges and complexities of these subjects are generally not considered in current engineering or business curricula. In this paper, we report on the development and delivery of a graduate-level course dedicated to Change and Configuration Management and discuss a vision for a new digital enterprise curriculum. The course was developed in close partnership with industry and discusses the core elements, data structures, stakeholders, and workflows of change management and their role in the product lifecycle. The application of the industry standard CM2 methodology is emphasized as a strategy to provide control, maintain data integrity, and improve visibility and traceability of changes.

Quality of supply is one of the key priorities in electricity distribution network regulation. The UK electricity regulator, OFGEM, financially rewards and penalizes DNOs with respect to the overall quality of supply they deliver. This is being achieved by focusing on the average quality of supply performance system indices CI and CML. However, focusing on system performance does not necessarily improve the quality of supply of individual customers. Therefore, DNOs are subjected to Guaranteed Standards (GS) of performance, which set supply levels that must be met in each individual case. Failure to do so results in penalty payments. This paper addresses two GS of performance, namely the Multiple Interruptions and the Supply Restoration during Normal Weather standards. It also introduces a framework based on sequential Monte Carlo simulation (SMCS), which quantifies the likelihood of these GS exceeding their specified thresholds, applied to a very large real distribution network.

Element Management System (EMS) is a system to manage network element (NE) for Ethernet Passive Optical Network (EPON). This allows the user to manage all the features of each network element (NE) individually. Network element (NE) exposes one or more management interfaces that the EMS uses to communicate with and to manage them. EMS has been design to fulfill FCAPS criteria which consist of fault management, configuration management, accounting management, performance management and security management. EPON is an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier’s central office and a customer site. EPON build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PON (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.

Current networks require ad-hoc operating procedures by expert administrators to handle changes. These configuration management operations are costly and error prone. Active networks involve particularly fast dynamics of change that cannot depend on operators and must be automated. This paper describes an architecture called NESTOR that seeks to replace labor-intensive configuration management with one that is automated and software-intensive. Network element configuration state is represented in a unified object-relationship model. Management is automated via policy rules that control change propagation across model objects. Configuration constraints assure the consistency of model transactions. Model objects are stored in a distributed repository supporting atomicity and recovery of configuration change transactions. Element adapters are responsible for populating the repository with configuration objects, and for pushing committed changes to the underlying network elements. NESTOR has been implemented in two complementary versions and is now being applied to automate several configuration management scenarios of increasing complexity, with encouraging results.

Operation support system (OSS) operates on 24times7 basis managing fault, configuration, accounting, performance and security operations from various network elements in a VoIP network. In traditional telephony systems there was a single point of connection from the OSS to the switch. Today VoIP networks are multi-vendor based distributed systems handling voice, data and multimedia content with multiple network elements and element management systems. Service providers expect a carrier grade quality system with single interface from OSS and a transparent flow through configuration management and provisioning system in VoIP networks. The challenge to network vendors and OSS service providers is to provide and end-to-end intelligent flow-through provisioning system across the various network elements and management systems. This paper describes practical tested architecture principles, design and emerging trends of flow-through provisioning system that is scalable and secure to serve millions of customers in a VoIP network

The aim of this article is to identify the methodological potential of product management within the framework of traditional pedagogical methodology. The article examines the possibilities of extrapolating the basic principles of product management to the field of education, and theoretically substantiates and evaluates the prospects for applying product management in education and scientific research of its problems. Scientific novelty lies in the development of scientific ideas about the possibilities and limitations of product management in education, considering the humanitarian and socio-cultural specifics of the latter as a subject of scientific research. The work also contributes to the clarification of research guidelines in the context of broad extrapolation of the product management principles to education and scientific research. The authors have established that the potential of product management in education lies in the development of an educational environment that is tailored to the motivations, objectives and interests of students. The dominance of business values over humanistic ones, and the underestimation of the individual’s historical and socio-cultural experiences are the main limitations of product management. The authors have identified that when applied to pedagogy, the guiding principles of product management, such as customer focus, iteration, and the measurability of results, are conceptually correlated with the ideas of human-centrism and the theory of pedagogical creativity.

The main subject of the study is revealing “cultural routes”, by the evaluation of ancient roads which have cultural accumulation on and around them. Considering the unique character of cultural routes, their formation as a consequence of cultural accumulation in a region is the main objective of the project. The project aims to explore the basic principles of cultural route planning and management in regard to the values of historic, natural, rural, modern and archeological components of cultural accumulation and cultural landscapes. Means that can be used to conserve and sustain their specific character are sought. In doing this, the study is structured in two main parts. It both covers a theoretical framework of conceptual principles and a case study. In the first part, together with the development process of the cultural route concept with different definitions and classifications stated by researchers and organizations the study mainly discusses the principles of cultural route planning and management. In the second part, based on the theoretical research, the process from a road to a cultural route is reviewed through a case study together with its planning and management principles. As the case study of the study, the ancient road between Milas and Labraunda is selected since it has a potential of transformation to a cultural route. Assessing its areas rich in cultural, historical and natural heritage together with the archaeological, architectural and local values, the work is finalized by a spatial cultural route model.

Whereas BPR (Business Process Re-engineering or Business Process Re-design) is being offered as a means by which organizations may be able to respond to the challenge of increased competition, Process Improvement, on the other hand aims to improve productivity, product quality and competitive advantage. Fundamentally, both activities offer a means by which organizations may be able to deal with a rapidly changing business environment, through internal change. BPR extends the concept of process change (albeit rapid change through innovation) to include changes to the basic assumptions and principles of management. The results, however are not positive: estimates of between 50 and 70% of firms fail to achieve the expected dramatic gains from BPR. An alternative to BPR for software development organizations is Process Assessment and Process Improvement. This paper presents a Process/Product Quality Model which incorporates three separate evaluations: process conformance, process effectiveness and product quality as a means of evaluating ‘what is’, i.e. the current status of activities, within a software development organization. The model aims to identify possible areas for process improvement and to uncover all relevant issues which may affect attempts to implement improvement initiatives. Preliminary findings from a set of case studies conducted within software development organizations in Australia are presented in support of the usefulness of the model.
