The organization is like a living being - it is necessary to build, feed and nurture it, respond to its needs and recognize the different phases in which it is. It all means that it is a dynamic system that is constantly changing. One part of these changes refers to the arrival, but also the departure of people from the organization. However, the term "fluctuation" refers to a special type of departure. A certain rate of fluctuation is expected, due to factors such as retirement or career advancement. However, when employees leave the organization because they are dissatisfied, unmotivated or under stress, it means that something is wrong with the organization. In addition, fluctuation costs a lot - not only when it is necessary to find a new employee, but also to introduce him to the job and make him a member of the team, and all that takes time and is therefore a big expense. It is of immeasurable importance to know, monitor and understand the possible forms of labor force fluctuations in order to be able to manage them, which is the focus of the topic of this paper.

Background: This study examines the management of small and medium-sized enterprises (SMEs) in crisis conditions, with a focus on the impact of the COVID-19 pandemic. It aims to identify strategies and best practices for enhancing SME resilience and sustainability. Methods: The research adopts a comprehensive literature review approach, analyzing previous studies and reports on SME management during crises. It also incorporates case studies and empirical data to provide practical insights. Results: The analysis reveals that SMEs face unique challenges during crises, such as disrupted supply chains, reduced consumer demand, and financial constraints. However, innovative solutions, collaboration among stakeholders, and supportive government policies have played a crucial role in enabling SMEs to adapt and recover. Conclusions: Based on the findings, it is evident that effective management practices, including adaptation, digital transformation, financial management, and crisis planning, are vital for SME survival and growth in crisis conditions. Collaboration and networking among SMEs, along with supportive government policies, contribute to collective recovery and sustainability. The study underscores the importance of ongoing research and development in SME crisis management, with a focus on resilience-building strategies, sustainable business models, and addressing the psychological well-being of SME stakeholders

To achieve greater sustainability of the traffic system, the trend of traffic accidents in road traffic was analysed. Injuries from traffic accidents are among the leading factors in the suffering of people around the world. Injuries from road traffic accidents are predicted to be the third leading factor contributing to human deaths. Road traffic accidents have decreased in most countries during the last decade because of the Decade of Action for Road Safety 2011–2020. The main reasons behind the reduction of traffic accidents are improvements in the construction of vehicles and roads, the training and education of drivers, and advances in medical technology and medical care. The primary objective of this paper is to investigate the pattern in the time series of traffic accidents in the city of Belgrade. Time series have been analysed using exploratory data analysis to describe and understand the data, the method of regression and the Box–Jenkins seasonal autoregressive integrated moving average model (SARIMA). The study found that the time series has a pronounced seasonal character. The model presented in the paper has a mean absolute percentage error (MAPE) of 5.22% and can be seen as an indicator that the prognosis is acceptably accurate. The forecasting, in the context of number of a traffic accidents, may be a strategy to achieve different goals such as traffic safety campaigns, traffic safety strategies and action plans to achieve the objectives defined in traffic safety strategies.
