Smart cities are included in the literature as a technology-based concept that has been on the agenda in recent years and whose framework is constantly changing with the changes in technology. There are different frameworks and indexes to define the smartness of a city. Smart City Index 2021 published by Institute for Management Development (IMD) and Singapore University of Technology and Design (SUTD) is one of the accepted studies in the world. In the report of Smart City Index 2021, 118 cities are evaluated in five criteria namely health & safety, mobility, activities, opportunities (work & school) and governance. To re-evaluate the cities and compare the results, a Multi-Criteria Decision Making (MCDM) process including Entropy based Complex Proportional Assessment (COPRAS) and Addivite Ratio Assessment (ARAS) methodology is applied in this paper. To prioritize the criteria, entropy weight method is used. 118 cities are ranked both technologically and structurally using the COPRAS and ARAS method. As a result of the analyses, according to these methods, the rankings of the smart cities are the same. Also, when technologically smart cities are listed, it is determined that the first three countries are Zhuhai, Shenzhen, Nanjing, and at the same time, Abu Dhabi, Chongqing, Hangzhou in terms of structurally.

Pollution of the night sky by artificial light has now become an important element of the modern city landscape. The decline in the quality of the sky observed at night in urban areas has already been noticed even by residents unaware of its origin. A starry sky is nowadays not easy to observe even in places far from large conurbations or smaller cities. More and more places are losing access to the previously natural privilege of observing the dark sky, and their inhabitants are thus systematically exposed to all the direct and indirect negative effects of this phenomenon. Monitoring the brightness of the night sky is gaining interest from a growing number of interdisciplinary research groups being established around the world, including Poland. In Toruń, the first measurements of the magnitude of this phenomenon, together with the determination of its spatial scale, were started using handheld devices in 2017. In the following years, efforts were made to improve the data acquisition process by creating a prototype – a technology demonstrator and, consequently, a commercial version of an automatic device measuring the surface brightness of the night sky. This paper presents the stages of the project aimed at developing a light pollution monitoring system, which has been consistently implemented in Toruń. The most important component of this system is a measuring device of our own design and construction. The monitoring system designed and operating in Toruń, starting in 2019, is being further developed with new components and monitoring (measurement) sites being systematically added, making the city’s observation network increasingly dense. The devices built using the LoRa standard for wireless data exchange implement the concept of the Internet of Things, fitting in with the objectives of a smart city.

Purpose: The outbreak of the Covid-19 pandemic has caused a revolution in human resource management in all organizations. Particularly important from a social point of view, changes have occurred in the organization of work and human resource management (HRM) in public institutions providing services to the public. On the one hand, it was necessary to secure the work of these entities so that the continuity of their work was maintained. On the other hand, the possibility of contamination of employees had to be limited. For this reason, Smart City solutions were started to regulate contacts between employees and between employees and customers. The aim of the article is an attempt to state whether the changes introduced in the HRM process in selected city offices in Poland were an expression of social responsibility, contributed to the improvement of the quality of work of officials and customer service of these offices. Design/methodology/approach: The research allowing for this answer was carried out on the basis of the Customer Satisfaction Index (CSI) method, and the sample in the research were employees of selected city offices. Research limitations/implications: It was found that the CSI method can be used equally effectively in the satisfaction of external and internal customers. Practical and social implications: The conducted study allowed for the conclusion that the assessment of the quality of intelligent solutions related to the area of social responsibility undertaken as part of human resource management was assessed by the respondents at an average level. Originality/value: The original element of the study on the basis of which the article was prepared was the use of the CSI method to survey employee satisfaction with work based on Smart City solutions.

Surveys performed among the residents of Zabrze indicate that in 2021 the majority of respondents (67%), wishing to use public services provided by the local government, still preferred to visit the office in person. Residents noticed negative aspects of direct service, such as queues of people waiting for the case to be completed (26%), excessive bureaucracy (24%) or lack of parking spaces (18%). However, they counted on help in completing the necessary formalities by officials who should be: professional (20%), communicative (18%) and kind (17%). The use of the digital platform (ePUAP) dedicated to customer service was reported by 32% of respondents. At the same time, as much as 40% of the respondents, in order to save time and to simplify procedures, declared their will to use innovative methods of remote contact with public administration (e.g. via social media). The COVID-19 pandemic showed that it was possible to increase (even by 250%) the number of cases handled remotely, which with over 90% of households in Poland with access to a computer network creates opportunities for integrated development as part of the Smart City idea. The aim of the paper was to identify the residents’ expectations related to the provision of public services by local administration. Precise determination of the ways of perception of both direct and remote customer service has not only an application value. It also allows for further research study on the management of local government, including the organization of management control, as well as social communication of local governments.

A key role in the development of smart Internet of Things (IoT) solutions is played by wireless communication technologies, especially LPWAN (Low-Power Wide-Area Network), which are becoming increasingly popular due to their advantages: long range, low power consumption and the ability to connect multiple edge devices. However, in addition to the advantages of communication and low power consumption, the security of transmitted data is also important. End devices very often have a small amount of memory, which makes it impossible to implement advanced cryptographic algorithms on them. The article analyzes the advantages and disadvantages of solutions based on LPWAN communication and reviews platforms for IoT device communication in the LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. It describes how to configure an experimental LPWAN system being built at the Department of Computer Science and Telecommunications at Poznan University of Technology for research related to smart buildings.
