Abstract: The examination of the primary climatic indicators, air temperature and rainfall, at the Drobeta Turnu Severin meteorological station for the period 2011-2022, allowed for the identification of increasing or declining trends. The entire study was developed using three different time frames of analysis: monthly, seasonal, and annual. The results indicate the specificities for each climate parameter on each of the three-time scales. The yearly trends for mean temperature are primarily increasing, while the annual trends for rainfall are generally decreasing. Because of the fluctuation of meteorological elements, air pollution has varying characteristics based on the geographical and topographical qualities of the urban region. This study's findings help to understand the seasonality of the overall air quality and the interaction between meteorological conditions and air contaminants. The Air Quality Index (AQI) was used to assess air quality. The AQI revealed that the air quality in Drobeta Turnu Severin is normal.

Abstract: In the present paper, an optimization method is presented for a route (a line) for public transport of people within the radius of the Municipality of Drobeta Turnu Severin. The current conditions regarding the public transport of people were presented, measurements were made on the route and trips were surveyed, these data being necessary to establish the input values for optimization. The most important result of this optimization is the establishment of an optimal distance between the stations on the analyzed route, a distance that ensures a minimum travel time for passengers, at an acceptable commercial speed and imposed by the traffic conditions specific to the Municipality of Drobeta Turnu Severin.

Abstract: The paper presents statistics of navigation events occurring on the Romanian sector of the Danube, in general and focused on those whose consequences represented a potential danger of pollution of the Danube water.The information presented and analysed shall be based on publicly available information provided and made available by the relevant competent authorities.The large amount of cargo transported per transport unit (approximately 1000 tons) can cause pollution with the most adverse consequences for the marine environment, but also for live animals and vegetation in the event of a navigation accident. Improper handling of cargo in oil terminals can also lead to accidental pollution with major consequences for the environment, for live animals and vegetation.Thus, involuntary stranding, collision between two ships, fire on board are direct sources of pollution when the integrity of the hull is affected, and fuels, lubricants, greases on board, and or cargo end up in the marine environment.The actions carried out to eliminate the consequences of pollution on the Danube from ships have different aspects and methods of intervention depending on the area where the pollution occurred, the polluting.

Abstract: The paper presents the importance of the sustainable development of means of transport. The biggest challenge facing the transport sector is to significantly reduce emissions and become sustainable. The sustainable development of transport also leads to a sustainable development of human society, by ensuring the circulation of goods, which has become a distinct, independent branch of the national economies and the European economy. For the EU, it is very important that Europe's economy grows sustainably and sustainably – a central aspect of its policies. The EU also plays a key role in promoting sustainable development worldwide.

Abstract: According to the EU, Circular economy represents a development strategy that entails economic growth without increasing consumption of resources, deeply transform production chains and consumption habits and redesign industrial systems at the system level. The decisive economic branch in ensuring circularity is industry. Thus, the engineer becomes the key to success, but for this he must be trained in order to support the sustainability of production. Through the curricula of the Department of Engineering and Management of Technological Systems (IMST), students are trained in fields such as engineering and management, environmental engineering and marine engineering and navigation. The sustainable integration of future engineers in industrial activity is an older concern that, in the current context, must be supplemented with notions and applications regarding the circular economy. The paper presents the authors' proposals for the completion of some syllabuses that develop specific competences and abilities for the circular economy.

Abstract: Simulators have become indispensable tools in modern education, revolutionizing the way we learn and train, particularly in the maritime industry. This article explores the pivotal role of simulators in enhancing the learning process, focusing on their application within the maritime sector. We delve into the benefits of simulator-based training, such as realistic scenario replication, risk mitigation, and cost-effective skill development. Furthermore, there are examined the evolving technology behind maritime simulators, emphasizing their contribution to safer, more competent, and environmentally conscious seafaring practices in a rapidly changing world.
