Leveraging on the fourth industrial revolution by African accountants in the sustenance of SDGs and AU Agenda 2063

AbstractThe research sought to assess the use of 4IR technologies by the accountancy profession in Africa in the sustenance of SDGs and AU Agenda 2063. The investigation adopted a pragmatic approach, associated with mixed‐methodological approach. The target population for the study was 114,800 Professional Accountancy Organisations (PAOs) members from all 44 countries in Africa who were members of the Pan African Federation of Accountants (PAFA). Online questionnaires and telephone interviews were administered to gather data. A total of 267 responses were received out of 114,800 members representing 0.23% of the population. Forty‐eight accountants were interviewed by telephone using the snowball sampling technique. Quantitative data gathered from online questionnaires was analysed using the IBM Statistical Package for Social Sciences (SPSS) version 26 and ATLAS.ti 9 was used to analyse responses from interviews. The study showed that accountants in Africa had heard about 4IR technologies, with the Internet of Things (IoT) mostly used and known by accountants. The study established that 4IR technologies improved the standard of living, reduced social marginalisation, eased manual work, improved agricultural productivity, reduced environmental pollution, improved health services, financial inclusion and knowledge sharing. These benefits are critical for achieving SDGs and the African Agenda 2063. Accountants are recommended to continuously train and retrain on new and trending technologies like computerised audits, big data analytics, machine learning, artificial intelligence, robotics, bitcoin and its risks in the monetary systems, cyber security in the 4IR era, cloud computing and information management systems to sustain SDGs and AU Agenda 2063.

STUDY OF REQUIREMENTS AND CYBER SECURITY ANALYSIS OF THE SOFTWARE OF INFORMATION AND CONTROL SYSTEMS OF NPP, IMPORTANT FOR SECURITY

In order to counter cryptoattacks on elements of critical infrastructure, in particular on computer control systems of nuclear power plants, the goal achieved in this work is to analyze the requirements for computer security (cyber security) of the software of this system, which are relevant to the stage of its design, development and operation, as well as proposed criteria and methodology for calculating the quality of compliance with these requirements. To achieve the goal, the first section of the article provides information on standards and identified requirements for software cyber security. In the second section, an analysis of the requirements is carried out and an approach to software development is described, taking into account these requirements and analyzing their consideration. In the third section, an approach to calculating the performance indicator of software cyber security requirements is proposed. The fourth chapter provides an example of the application of this approach to the existing computerized NPP management system to assess compliance with cyber security requirements. The article discusses the requirements of the international standard IEC62645 and the industry standard of Ukraine “NP 306.2.237-2022”, which are related to the development of software for the computer control system of nuclear power plants. Ensuring cyber protection of the software of the NPP computer management system is a complex task that includes administrative, legal, technical, cultural, and organizational components. From the point of view of software development and operation, the main cyber security measures include software code verification, ensuring the absence of hidden functions, implementing physical equipment protection, security of software components, authentication, security during data exchange. To determine the compliance of the software with the requirements of cyber protection, it is necessary to determine the requirements applicable to each component of the software and conduct an analysis of their implementation. This action should occur continuously during the development of new software and software evaluation of existing computer control systems. After the analysis of the applicability and fulfillment of the requirements, the calculation of the coefficient of the fulfillment of the requirements can be carried out. It was noted that cyber protection is only a component of the quality of the software of the NPP computer control system, which is important for the performance of security functions. The analysis of requirements and the calculation of the coefficient of their fulfillment can be an integral part of the complex model of the software development process of the computer system of NPP management.

Evaluation of the efficiency of computer monitoring based on selected parameters of dairy herd behaviour in relation to daily milk yield

The study analysed the indicators of welfare and motor activity of animals to support farmers in taking decisions on breeding management in Polish Holstein-Friesian black-and-white cows. The survey involved 236 cows during a 305-day lactation period, kept in an open-sided free stall barn, before and after furnishing the complete computer management system DeLaval DelPro. It evaluated the motor activity and breeding parameters of cows assigned to three groups (I, II, III), depending on daily milk production. It was demonstrated that the highest-yielding cows spent more time (12.5 vs 10.5 h/day) lying down and resting than the lowest-yielding cows. The highest motor activity of cows (29.66% of the herd) was observed in the morning between 3:00 AM and 6:00 AM, and the lowest (6.78% of the herd) in the evening between 9:00 PM and 00:00. The monitoring significantly (P ≤ 0.05) improved all the evaluated breeding parameters (insemination index, inter-pregnancy interval, and calving interval) in the highest-yielding group of cows. Based on the outcomes, the use of livestock management software should be recommended to improve the welfare and breeding indicators of Polish Holstein-Friesian black-and-white cows.

Perancangan Desain Sistem Inventori Tool Crib Pada Bengkel Mesin

Information management for inventory is very important to help companies or organizations manage their inventory more efficiently and effectively. With good information management, companies can monitor and control the quantity of goods available, avoid shortages or excess stocks, and optimize the process of sending and receiving goods. The equipment management system in the POLMED Mechanical Engineering Workshop Tool Crib is still conventional, not yet using a technology-based (computer) management system. Where equipment borrowed by students or other stakeholders is still recorded in a form and there is no information management-based recording. So that the number of tools, the condition of the tools and who borrows the tools cannot be controlled properly. And problems/issues arise when the equipment is often not in place or missing.

Enhanced Dual Convolutional Neural Network Model Using Explainable Artificial Intelligence of Fault Prioritization for Industrial 4.0.

Artificial intelligence (AI) systems are increasingly used in corporate security measures to predict the status of assets and suggest appropriate procedures. These programs are also designed to reduce repair time. One way to create an efficient system is to integrate physical repair agents with a computerized management system to develop an intelligent system. To address this, there is a need for a new technique to assist operators in interacting with a predictive system using natural language. The system also uses double neural network convolutional models to analyze device data. For fault prioritization, a technique utilizing fuzzy logic is presented. This strategy ranks the flaws based on the harm or expense they produce. However, the method's success relies on ongoing improvement in spoken language comprehension through language modification and query processing. To carry out this technique, a conversation-driven design is necessary. This type of learning relies on actual experiences with the assistants to provide efficient learning data for language and interaction models. These models can be trained to have more natural conversations. To improve accuracy, academics should construct and maintain publicly usable training sets to update word vectors. We proposed the model dataset (DS) with the Adam (AD) optimizer, Ridge Regression (RR) and Feature Mapping (FP). Our proposed algorithm has been coined with an appropriate acronym DSADRRFP. The same proposed approach aims to leverage each component's benefits to enhance the predictive model's overall performance and precision. This ensures the model is up-to-date and accurate. In conclusion, an AI system integrated with physical repair agents is a useful tool in corporate security measures. However, it needs to be refined to extract data from the operating system and to interact with users in a natural language. The system also needs to be constantly updated to improve accuracy.

Malicious Web Links Detection - A Comparative Analysis of Machine Learning Algorithms

"One of the most challenging categories of threats circulating into the online world is social engineering, with malicious web links, fake news, clickbait, and other tactics. Malware URLs are extremely dangerous because they represent the main propagating vector for web malware. Malicious web links detection is a challenging task because the detection mechanism should not influence the consumers’ online experience. The proposed solutions must be sensitive enough, and fast enough to perform the detection mechanism before the user accesses the link and downloads its content. Our paper proposes three goals. The main purpose of this paper is to refine a methodology for malicious web links detection that may be used to experiment with machine learning algorithms. Moreover, we propose to use this methodology for training and comparing several machine learning algorithms such as Random Forest, Decision Tree, K-Nearest Neighbor. The results are compared, justified, and placed in the malicious web links literature. In addition, we propose to identify the most relevant features and draw some observations about them. 2010 Mathematics Subject Classification. 68T99, 68U99. 1998 CR Categories and Descriptors. 68T99 [Artificial Intelligence]: Applications and Expert Systems – Experiments for Malicious Web Links Detection; 68U99 [Management of Computing and Information Systems]: Security and Protection – Malicious Web Links.

Analytical aspects of application of intelligent methods of management of computer systems in transport infrastructure projects

The object of research is the processes of monitoring and intelligent control of computer systems in transport infrastructure projects. In the design and operation of computer networks, an urgent task is to solve the problem of providing quality services with distributed information processing, which is largely determined by the development of the network management mechanism of the transport system. The increase in the amount of digital data creates security and protection of information solely at the expense of the aspects of their design and operation. The paper considers the methods of intelligent network management of computer systems in transport infrastructure projects, analyzes their principles of operation and functions in relation to the network infrastructure. Methods using intelligent agents are analyzed and the results of their application to computer network management are presented. The use of intelligent agents in computer networks and systems allows automating complex tasks, optimizing resources and increasing the efficiency of the network of the transport economy system. They can contribute to increased productivity, safety, and user satisfaction. The considered algorithms for processing the results of the examination of the load of the transport network infrastructure are used to ensure effective management of the transport system. Processing algorithms allow analyzing the current state of traffic in different sections of the transport network. These algorithms can be used to develop optimal traffic distribution strategies. A case of their application is presented. One of the main tasks of the transport sector is to ensure traffic safety, which can be achieved by quickly processing information and receiving it distributed to all levels of the management system for quick analysis, processing, and (if necessary) response. The paper proposes to use methods of monitoring, expert evaluation of the general state of the computer network and the development of management decisions that take into account the peculiarities of the structure and functioning of computer systems in transport infrastructure projects. This ensures the ability to transmit information with specified service quality parameters with minimal network resource consumption. The research presented in this paper can be used in practice in organizations and enterprises of the transport sector during the reorganization, improvement, or integration of individual components of the information system.

LazySort: A customized sorting algorithm for non-volatile memory

Due to the development of new non-volatile storage technologies, bridging the access delay gap between storage and memory has been promoted. Therefore, since the volume of data continues to increase, the need for new types of non-volatile storage for high-performance computing and database management systems significantly increases. As a basic algorithm of the database management system, external sorting is widely used but suffers from numerous I/O operations caused by the frequent data exchange between the memory and external memory. Non-volatile memory (NVM) is a promising solution. However, the traditional external sorting algorithm is only designed for disk storage and cannot be used for NVM. To solve this issue, we propose LazySort, which is a novel external sorting algorithm that exploits the NVM byte addressing mechanism and the orderly distribution of data to improve the sorting efficiency. Specifically, LazySort first detects the ordered data segment in the memory and then records the storage location of the data segment as well as its maximum/minimum values in an index table named ITable. Next, to reduce memory usage and accelerate the sorting procedure, LazySort performs an optimization strategy RunMerge to merge non-intersecting data blocks according to the range of ITable records. To verify the performance of LazySort, we built an experimental platform with the NVM-DRAM storage architecture combining NVM and dynamic random access memory (DRAM) and conducted a series of experiments. The experimental results show that LazySort is more efficient than the traditional external sorting algorithm, since the sorting time of LazySort is shortened by 93.08% and the number of NVM write operations is reduced by 49.50%. Moreover, the advantage of LazySort over traditional algorithms is more significant when the data amount increases.

Influence of technology adoption on organizational performance: evidence from Paraguayan microenterprises

The use of technology can assist microenterprises in increasing their productivity, competitiveness, and effectiveness, as well as improving customer satisfaction. The goal of this study was to compare the administrative performance of participating microenterprises before and after implementing a computerized management system. Thirty-two microenterprise owners and managers were selected for this case study and participated in four phases of the action research method: an exploratory phase to identify needs, a planning phase during which the first performance measurement was conducted, an implementation phase, and finally a post-implementation evaluation phase in which a new performance measurement was performed. Based on the specific needs identified in the exploratory phase, a tailor-made management software was designed and implemented in the participating microenterprises. The Student’s T-test results show a statistically significant positive change. Most of the participants agree that the implementation has contributed to a significant improvement in administrative tasks and processes, making their overall work more efficient, more accurate and with greater speed. This indicates that a correct implementation of information and communication technologies based on specific needs has a positive impact on the administrative performance of microenterprises. The method used in this study could be useful for successful technology adoption in similar organizations.

Application of a Blockchain Model in the Energy Market for Social Goodness: A Simulator to Generate Transactions

An application of blockchain technology to manage electricity flows in a Microgrid (MG) is studied. The grid is considered for civil use, equipped with generation and storage systems, and interfaced with the national grid. It is composed of energy nodes such as user, generator, accumulator, and customs officer node, each characterized by its own time profile, in a limited time interval, of energy flow (consumption, generation, charge/discharge, purchase/sold). The proposed management strategy is based on the principle of free trade managed through blockchain. A simulation tool is developed to evaluate the electricity flows for different scenarios. The blockchain of energy transactions is generated by means of a dedicated software and having as reference a set of ethical/economical rules. It is demonstrated that it is possible to design energy management and exchange systems that allow in an economic way, within the delicate balance between energy availability, technology, market, safety, freedom and needs of individual users, to optimize the exchange of resources and to decrease waste. This blockchain exchange strategy can be implemented without building new plants and avoiding expensive and complex systems, by installing only bidirectional meters equipped with telecommunication, in addition to a common computer management system. The aim of this work is to demonstrate importance and technical feasibility of enforcing rules on the correct use of energy. The peer-to-peer operating mode is different from the technique currently in force in conventional energy systems, in which always a control body (energy, economic, financial) supervises and manages any transaction between users.

Maintaining computer network security has long been an essential component of computer administration. Network security has become essential to companies’ safety and steady development in real-time implementation for diverse physical domains employing computers. Establishing a specific physical domain has consistently included a priority job of improving the safety of computer systems management. Study results on the practical implementation of machine intelligence in network security maintenance. Specifically, this paper examines and offers security management techniques for computer network data protection to establish an all-encompassing security shield for networked computers, with the ultimate goal of improving the safety and reliability of the net-worked computers used in commercial settings. Furthermore, the comprehensive research analysis determines an architectural model for machine intelligence-based network security maintenance (MI-NSM), implying an intrusion detection scheme with a novel neural network system. Labelling important properties of objects or data points and searching for commonalities allows the auto-mobile’s AI to distinguish between a human, the street, another car, and the sky. The simulation evaluation is performed using the NS2 simulator and observes the security maintenance efficiency over the current security solutions.

Need for Improvements in Medical Device Management in Low- and Middle-Income Countries: Applying Learnings from Japan's Experience.

Medical devices provide important infrastructural support in modern healthcare systems. However, in low- and middle-income countries (LMICs), inadequate maintenance and management of devices due to a shortage of healthcare personnel (not only doctors and nurses but also other professionals including biomedical engineers [BMEs]) has resulted in inefficient and weak healthcare systems. High-income countries, including Japan, have resolved these problems by developing human resources and technologies to maintain and manage these systems. In this paper, we discuss the possibility of mitigating these problems in LMICs through human resource development and technology, based on lessons from Japan's experience. The problem of medical device management in LMICs stems from the fact that there are few professionals, such as BMEs, in charge of the management of medical devices and that clinical engineering departments in charge of device management have not been established. Since the 1980s, Japan has introduced a licensing system for BMEs, establishing operational guidelines to clarify their responsibilities within hospitals and using technology to utilize data and reduce workloads. Nevertheless, workload problems and high costs required to introduce computerized management systems persist. Moreover, it would be difficult to implement the same measures as those adopted in Japan in LMICs where there is an overwhelming shortage of medical personnel. It may be necessary to further reduce workloads for data entry and device management; use up-to-date, inexpensive, and user-friendly technology; and train non-BME personnel to operate and maintain equipment.
