AbstractBlockchain can be thought of as a distributed database allowing tracing of the origin of data, and who has manipulated a given data set in the past. Medical applications of blockchain technology are emerging. Blockchain has many potential applications in medical imaging, typically making use of the tracking of radiological or clinical data. Clinical applications of blockchain technology include the documentation of the contribution of different “authors” including AI algorithms to multipart reports, the documentation of the use of AI algorithms towards the diagnosis, the possibility to enhance the accessibility of relevant information in electronic medical records, and a better control of users over their personal health records. Applications of blockchain in research include a better traceability of image data within clinical trials, a better traceability of the contributions of image and annotation data for the training of AI algorithms, thus enhancing privacy and fairness, and potentially make imaging data for AI available in larger quantities. Blockchain also allows for dynamic consenting and has the potential to empower patients and giving them a better control who has accessed their health data. There are also many potential applications of blockchain technology for administrative purposes, like keeping track of learning achievements or the surveillance of medical devices. This article gives a brief introduction in the basic technology and terminology of blockchain technology and concentrates on the potential applications of blockchain in medical imaging.

PurposeThis paper discusses how the features of blockchain technology impact supply chain transparency through the lens of the information security triad (confidentiality, integrity and availability). Ultimately, propositions are developed to encourage future research in supply chain applications of blockchain technology.Design/methodology/approachPropositions are developed based on a synthesis of the information security and supply chain transparency literature. Findings from text mining of Twitter data and a discussion of three major blockchain use cases support the development of the propositions.FindingsThe authors note that confidentiality limits supply chain transparency, which causes tension between transparency and security. Integrity and availability promote supply chain transparency. Blockchain features can preserve security and increase transparency at the same time, despite the tension between confidentiality and transparency.Research limitations/implicationsThe research was conducted at a time when most blockchain applications were still in pilot stages. The propositions developed should therefore be revisited as blockchain applications become more widely adopted and mature.Originality/valueThis study is among the first to examine the way blockchain technology eases the tension between supply chain transparency and security. Unlike other studies that have suggested only positive impacts of blockchain technology on transparency, this study demonstrates that blockchain features can influence transparency both positively and negatively.

AbstractThis study aimed to offer an in-depth insight into intellectual dilemmas associated with a comprehensive approach to national defence using Estonia as an example to demonstrate that comprehensive approach in itself may not be enough to feel safe and secure. The authors focused on two specific theoretical questions. First, how security threats are determined in Estonia, including the impact of such a phenomenon as macro-securitization? Second, how various levels of comprehensive approach relate to each other in the way that a shared security culture will be created? In this way, the aim of this article was not only to shake the foundations of national defence in Estonia but also to contribute to the improvement of the current model to ensure that it actually works in practice.

Blockchain is an information technology solution for distributed digital record. Its main properties are secure, traceable, and transparent. Blockchain was first proposed for bitcoin, a decentralized virtual digital currency. Recently, blockchain draws attentions of researchers, entrepreneurs, and investors, because people found that blockchain technology can revolutionize many business practices. This paper describes the fundamentals of blockchain technology, including data structure, data distribution, and transaction execution and validation. This paper also discusses the representative blockchain protocols and development platforms. In addition, this paper outlines the potential applications of blockchain technology and the broader impact it might bring to industry, business, and beyond.

Unmanned aerial vehicles (UAVs) are present in our lives, and although they are mostly connected to military purposes, they are becoming more present in the commercial and civilian sector. Possible applications of UAVs in the commercial and civilian sector will open new possibilities for further research and development of UAVs. This movement can bring new investment and new jobs, but at the same time, it will influence the way some activities are being done now. The use of UAVs brings savings in the production cycles and improve current operations in various industrial sectors. The chapter gives a definition and explains different types and potential applications of unmanned aerial vehicles in the word as well as the potential economic impact of their development and use. In the second part, the chapter analyzes the application of drones in Turkey and Croatia. Although different in terms of their size and the number of inhabitants, both countries are at the same level in relation to UAV application. Applications in both countries are compared, and after that, a conclusion is drawn.

Blockchain is an emerging technology that is based on the concept of distributed ledgers. It allows for pervasive transactions among different parties and eliminates the need for third-party intermediaries. Several of blockchain's characteristics make it suitable for use in the agriculture sector. Some of the potential applications of blockchain include efficient management of the food supply chain and value-based payment mechanisms. The products of agriculture are usually the inputs for a multi-actor distributed supply chain, in which case the consumer is usually the final client. The food chain involves several actors including farmers, shipping companies, distributors, and groceries. This makes the entire system to be distributed with multiple actors playing different roles throughout the chain. This currently used system is inefficient and unreliable in various aspects. This project aims to leverage blockchain technology to solve and address discrepancies involved in food supply chains.

E-voting is one of the valid use cases of blockchain technology with many blockchain e-voting systems already proposed. But efforts that focus on critical analysis of blockchain e-voting architectures for national elections from stakeholders’ perspectives are mostly lacking in the literature. Therefore, government decision-makers and election stakeholders do not yet have a sufficient basis to understand the potential risks, challenges, and prospects that are associated with blockchain e-voting. This paper demonstrates how the use of the Architecture Trade-off Analysis Method (ATAM) can enable stakeholders in national elections to understand the risks, prospects, and challenges that could be associated with a blockchain e-voting system for national elections. By using a study context of South Africa, a proposed blockchain e-voting architecture was used as a basis to aid election stakeholders to reason on the concept of blockchain e-voting to get them to understand the potential risks, security threats, critical requirements attributes, and weaknesses that could be associated with using blockchain e-voting for national elections. The study found that blockchain e-voting can prevent many security attacks, internal vote manipulation, and promote transparency. However, voter validation and the security of the blockchain architecture are potential weaknesses that will need significant attention.
