Tourism evolves constantly due to the changes occurring in contemporary civilization, its dynamics integrating in the general process of development

ENTREPRENEURSHIP IN TOURISM - REASONS, NECESSARY RESOURCES AND IMPEDIMENTS

Tourism is a complex activity involving a combination of material (accommodation, transport, tourist attractions) and psychological (specific attitudes, desires, human emotions) elements. In literature, there are numerous definitions demonstrating the complexity and importance of the tourism phenomenon. In general, entrepreneurship in tourism means enterprises, complex activities at both macro- and micro-economic levels. The concept of opportunity is a main theme in entrepreneurship. The goals of this paper concern the identification of reasons and resources necessary to establish a tourism firm. The paper analyses these aspects between 2005 and 2013 to identify possible changes during the years from the perspective of the Romanian enterpriser behaviour. The research method consisted in Eurostat and Romania statistic data collection, processing and interpretation. One of the issues related to Eurostat was the lack of complete data on tourism: we found only data regarding entrepreneurship in hotels and restaurants in 2005, which limited our study options and prevented us from approaching other tourisms sectors such as travel agencies, tour-operators, rural tourism and agri-tourism, bread & breakfasts, motels, and camping sites. The study on 2013 relied on a questionnaire applied online to accommodation units in Romania, and involved a wider range of Romanian tourism operators. Result analysis pointed out the fact that Romanian entrepreneurs wish to be financially independent, to be their own bosses, and to make more money – all important reasons in launching a tourism business in both 2005 and 2013. Analysis of financial resources used by Romanian entrepreneurs in tourism shows that most of the funds used by Romanian entrepreneurs in the field come form their own resources and from families and friends; bank credits, European funds or support from the authorities represent a smaller share in both studied years

Begin again: election campaign and own opinions among first-time voters in Romania

Objective: This article analyzes under what circumstances first‐time voters are likely to be influenced by the election campaign or by their opinion prior to campaign in their vote choice. Methods: It uses individual‐level data from an original online survey conducted among Romanian first‐time voters in the November 2019 presidential election. Results: The results indicate that those who trust politicians, find the campaign informative and use social media are influenced by election campaign. Those with higher political knowledge and interest follow their precampaign attitudes in casting the vote. Conclusion: The study reveals the existence of distinct causal mechanisms for young voters who are influenced at the polls by the election campaign or by their own attitude prior to campaign. This indicates the necessity to include the existence of an opinion prior to campaign in future analytical frameworks about voting behavior

1-[(E)-4-(Phenyl­diazen­yl)phen­yl]-3-pyrroline-2,5-dione

The title compound, C16H11N3O2, displays a trans configuration with respect to the azo group. The mol­ecule is non-planar; the maleimide ring forms a dihedral angle of 42.35 (4)° with the benzene ring bonded to its N atom and the mean plane of this benzene ring is rotated by 21.46 (8)° with respect to the azo group mean plane, which, in turn, forms a dihedral angle of 24.48 (7)° with the ‘terminal’ benzene ring. Mol­ecules in the crystal are π–π stacked along the [100] direction with a mean inter­planar distance of 3.857 (1) Å. In addition, C—H⋯O inter­actions link them into double layers parallel to the ac plane

Diverticulii esofagieni intratoracici. Tratament videotoracoscopic

Department of Surgery no. 4, Nicolae Testemitanu SUMPhBackground. Esophageal intratoracic diverticula (EID) represent a rare pathology. The position of EID on the esophageal tract implies different surgical tactics. Thoracotomy has been the intervention of choice. Videothoracoscopy (VTS) has suggested positive results in the treatment of this pathology. Objective of the study. Analysis of the advantages of VTS in comparrison with the traditional surgical approach in the treatment of EID. Material and Methods. The study involved 27 patients aged between 45 and 65 years, diagnosed with EID, hospitalized in the Thoracic Surgery Ward of the Clinical Republican Hospital "Timofei Mosneaga" during the period 2000-2021. The mean diameter of the EID was 7 cm. The average duration of the onset of symptoms was 6 months. Results. This study shows the advantages of VTS compared to the traditional thoracotomy. The duration of the VTS procedure was 2h 30 min., compared to 3h for the thoracotomy. The average duration of hospitalization was 5 days for the VTS and 11 days for thoracotomy. The patients received surgical treatment: 12 patients underwent VTS (4 - midthoracic diverticula, 8 - epiphrenic diverticula) and 15 were treated through thoracotomy. Conclusion. The traditional method has been the mainstay of treatment in patients with EID, yet in the last few years the minimally invasive technique is used to a greater extent. A VTS approach for the management of EID is safe and effective when performed by surgeons experienced in VTS esophageal surgery.Introducere.

Application of UAS Technology for the Development of Precision Agriculture

Precision agriculture often uses digital techniques such as satellites, UAS (unmanned aerial systems) and sensors to optimize agricultural production processes while reducing negative environmental impacts. Smart agriculture is data-driven, so a UAS can accurately receive and fairly distribute this information, allowing producers to take action based on individual soil circumstances. The paper aims to highlight the main advantages of UAS used in agriculture, depending on the type of wing (single-rotor, multi-rotor, fixed-wing and VTOL) and the sensors used. Also, within the work, the stages of making the digital orthophoto map at the Hoia farm, belonging to USAMV Cluj-Napoca, were analysed, with a view to further analyses on the state of the vegetation, using a DJI Phantom 4 Pro UAS model. Vegetation status can be assessed and quantified by different vegetation indices from images acquired in the visible, red and near-infrared spectral bands. Depending on their formulation, they can show a strong correlation with land cover and leaf and green area index (LAI and GAI), crop nitrogen uptake (QN), chlorophyll content, water stress detection, plant structure, photosynthesis, yield and growing conditions. Modern agricultural technology plays a vital role in increasing productivity to meet the demand for food for a growing global population, conservation and management of agricultural resources
