Corporate Information

В условиях развития информационного общества (Knowledgeable society - KS) информационные системы стали неотъемлемой частью любой организации, даже самой малой, независимо от реализуемых ими бизнес-процессов. Такие информационные системы принято называть корпоративными информационными системами (КИС), или Corporate Information System (CIS). Особые требования при разработке КИС предъявляются к обеспечению их информационной безопасности, что может быть реализовано путем разработки КИС в защищенном исполнении. Технологии blockchain являются очень перспективными не только при применении их в традиционных сферах - производстве, сервисе, на транспорте, но и для решения проблем безопасности и информационной, в частности. Анализу данной проблемы и подходам к ее решению и посвящена данная статья. At present, in the context of the development of Knowledgeable society, information systems are at now an integral part of any organization, even the smallest, regardless of the business processes they implement. Such information systems are commonly referred to as Corporate Information Systems (CIS). Special requirements for the development of CIS are made to ensure their information security, which can be achieved by developing a protected version of the CIS. In this article is considered the analysis of this problem and approaches to its solution. Block Chain technologies are very promising not only when applying them in traditional spheres - manufacturing, service, transport, but also to solve security and information problems, in particular.

The Impact

The purpose of this paper is to identify the impact and benefits of the latest information technologies on Accounting Information Systems (AIS). Taking into account the numerous papers related to new technologies and their application in the accounting profession within Industry 4.0, and conducted survey about perception of practitioners in Republic of North Macedonia, this paper summarizes the characteristics and key benefits of some of the new technologies for the functioning of AIS in the digital age. First of all, the evolution of AIS is elaborated, based on theoretical and empirical analysis of the accounting process from the appearance of the first AIS up to nowadays’ services and techniques available for supporting the accounting function. The first technology to be elaborated is Big Data and its potential to change the business landscape, especially in the field of automating operation processes, customer engagements, and predictive decision-making process. Secondly, the Blockchain Technology as an example of Distributed Ledger Technology (DLT), which adoption brings new possibilities in eliminating or redefining the role of entities external to the company. Cloud Computing i.e. Cloud Accounting is the third technology which is elaborated in this paper through the services it offers on the cloud, especially the way AIS process, store and backup the sensitive and confidential data. Last but not least, Artificial Intelligence (AI), a technology that could change the professional services, the need, and opportunities that are provided for a solution to the current accounting issues. In summary, taking into account the relevant literature and the perception of the respondents-practitioners, increased use of these technologies is necessary because their application reduces costs; increases transparency and confidence in information; flexibility, i.e. no time and space restrictions on their use, etc., which is especially useful in the current state of Pandemic, caused by the virus COVID-19.

Zero Carbon

Carbon emissions are categorised as Embodied Carbon (EC) occurring in the production phase and Operational Carbon (OC) occurring in the operational phase of buildings. The current focus on producing zero-carbon buildings, emphasises reducing OC and ignores the importance of reducing EC emissions. This study focuses on EC. Methods available in EC estimating currently produce estimates that often do not complement each other. This makes it important to develop a robust and accurate methodology for estimating EC. Blockchain is an emerging technology that has significant potential for transaction processing in supply chains. The construction industry being the second least digitalised industry, the adoption of innovative technologies is predominantly important. This paper explores the potential application of blockchain for accurate estimation of EC in construction supply chains. A detailed literature review and expert interviews revealed that, compared to traditional information systems, blockchain systems could eliminate issues in EC estimating highlighting its potential credible application for EC estimating. Scalability was identified as a feature that was lacking in a blockchain system, however, for EC estimating, its impact was identified as minimal. It will be difficult to generalise the findings of the study due to interview based qualitative methodology adopted in this study along with the fact that blockchain is an emerging and fairly new technology. However, a similar process could be followed by other studies to compare blockchain with traditional information systems, to evaluate the suitability of blockchain technology to develop prototype systems.

Summary Objectives: This paper aims to describe and analyze the prolonged efforts – spanning close to two decades – of developing and using electronic patient records in the large, university-based hospitals in Norway. Methods: This study belongs to an interpretative approach to the development and use of information systems. Results: The increase in organizational, institutional, political and technological complexity has been seriously underestimated. This paper describes and analyses the prolonged efforts – spanning close to two decades – of developing and using EPRs in the large, university-based hospitals in Norway. The investments involved were considerable, implying that a crucial aspect of these efforts has been the way alliances have been forged with public institutions and agendas. Conclusions: The conditions for small-scale, bottom-up and evolutionary approaches never succeeded in constructing themselves as a viable alternative to the larger, more sweeping electronic patient record initiative, reiterating a more general tendency to privilege the more comprehensive and daring projects.

Definition Of

Digital transformation in the public sector is an inevitable requirement for governments due to the growing complexity and interconnections of information systems, and to the demands of citizens, who are becoming better informed and are increasingly looking to more agile and innovative services. However, despite the willingness of many governments and public institutions, the results do not always tally with the original objectives. In the case of public procurement in Portugal, it could be said that digital transformation experience had an unexpected success in the European context, through a business model that is still quite unique in Europe. This result is much owed to the strong political determination, the experience gained from pilot projects, and to the involvement of many stakeholders, who contributed, in a consistent and innovative way, to the definition of the system. The system is not perfect: there are many challenges that need to be addressed in the coming years. Yet, it has enabled the Portuguese public administration to significantly grow in the digital era, so that today the State has a database containing structure information about public procurement, which is a unique case in many countries.
