Economic fluctuations impose a more significant challenge on prediction models, and pandemic modeling methodologies are primarily concerned with the variability of epidemic features, the efficiency of control measures over time, and the development of different viral variants. In this context, this paper correlates economic indicators with quantitative parameters of the last three respiratory virus pandemics, specifically the GDP and the unemployment rates, with a sample encompassing three European countries, the United Kingdom (UK), France, and Germany, that pass through the pandemics under study. The results provide intriguing information, such as the moderated and weak correlation factor between deaths with GDP in the Spanish flu and Swine flu, and the WWI and the 2009 crises can explain which. On the other hand, the correlation factors associated with COVID-19 show a weak to moderate correlation parameter with GDP and unemployment rates but present interesting numbers when the number of people fully vaccinated is compared with GDP. Also, as the correlation factor does not presente a strong relation between daily deaths and GDP, this indicates a necessity for comparison with other economic parameters.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"256 ","pages":"Pages 538-546"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the first step of creating individual products to the process of their storage, transportation, and placement on store shelves, every single step can be continuously monitored, thereby guaranteeing the appropriate quality. In the blockchain, data can be stored securely, unauthorized persons cannot modify the data, as it is a very complex task. As a result, the research aims to examine which blockchain technology is the most suitable for logistics and production processes, considering both efficiency and security aspects. By applying the smart contract, the third party can be excluded from the process, thereby increasing efficiency and security, while also reducing costs. As part of the practical implementation of the research, a blockchain that meets the conditions listed above will be created, and an Ethereum-based smart contract will also be written using the Solidity programming language. The research motivation is to create a blockchain and smart contract that are capable together of replacing centralized data storage while eliminating its security shortcomings. The purpose of creating the blockchain is to implement distributed Peer-to-Peer node-based data storage for logistics data in a decentralized environment. By creating a smart contract, blockchain-based data storage can become an automated process, making the server and system administrator redundant. The research aims to achieve the highest possible level of data storage security so that the data storage is performed automatically, thus reducing the tasks of the system administrator. The key point of this is the selection of the most optimal smart contract platform and the creation of the contract in which the data storage conditions can be defined. Through the practical application of the smart contract, some logistics processes are carried out automatically, thereby further increasing efficiency.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"253 ","pages":"Pages 49-58"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the implementation of AM in aviation presents challenges related to costs, quality, and certification, among others. This review examines the status of AM in the aviation sector through a literature review with the intention of identifying the research topics and the main conclusions. It highlights significant issues such as cost and quality, which have been widely discussed in various studies to disclose future research opportunities as a contribution for the adoption of these technologies in the industry. This review utilized a Scopus-based search, yielding 29 relevant articles for analysis. These articles predominantly explore AM’s application in aviation, addressing advantages, sustainability, costs, supply chain, technology, materials, and lifecycle issues. The findings underscore AM’s potential to improve ‘buy-to-fly’ ratios and enable supply chain decentralization, driven by digitalization and reduction in transportation and inventory needs. Authors also point to the transformative potential of this technology, despite ongoing challenges, such as installation and volume production costs, but also quality, mechanical properties, porosity, surface finishing, and process repeatability issues. On the other hand, several authors argue that AM has the potential to contribute significantly to the aviation industry evolution in diverse areas such as the production of lightweight structures, rapid prototyping, supply chain responsiveness, and customized component manufacturing. The review consolidates the objectives and major findings of the selected articles, providing a comprehensive overview of AM’s present role and future in the aviation industry.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"253 ","pages":"Pages 892-901"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CSR enhances a company’s reputation, attracts socially-conscious consumers, and boosts employee morale. Moreover, digital platforms amplify the impact of CSR initiatives, allowing businesses to engage with global communities. Despite extensive research on CSR in various contexts in the digital age, there is a notable gap in understanding its effects on organizational citizenship behavior and job satisfaction specifically within Vietnamese manufacturing firms. In such as context, this study examines the impact of corporate social responsibility (CSR) on organizational citizenship behavior (OCB) and job satisfaction of employees in Vietnamese manufacturing firms in the digital age. A self-administered questionnaire survey was conducted to collect data from employees working in manufacturing firms in Vietnam. After four months, we received 375 valid responses. Data was put into SPSS software for analysis. Our findings show that CSR towards the community does not have a significant relationship with employees’ OCB, while CSR towards the government has a very low level of impact on employees’ OCB. These findings suggest that not all CSR efforts are equally effective in fostering positive employee outcomes. Consequently, we propose targeted solutions to enhance CSR practices in Vietnamese firms to boost OCB and job satisfaction among employees, thereby contributing to both organizational performance and social well-being in the digital age.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"253 ","pages":"Pages 717-726"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
