Using the example of the city of Chernivtsi (Ukraine) the number of tourists visiting the city has been determined, the volume of services rendered and the average annual growth rate of tourism service implementation over the last five years has been calculated contributing to forecasting the volume of service delivery for the future.
The Impact of the Perception of Leisure on Recreational and Tourism Spaces in an Urban Area
Authors: Meyer Beata , Niezgoda Agnieszka 
Published: July 2018

AbstractThe purpose of the present paper is to attempt to identify relations between the changing perception of leisure and the creation of tourism and recreational spaces in urban areas. The authors focus in particular on changes associated with the so-called ‘third wave’ (Toffler2001), time compression (Niezgoda2017), and departure from synchronization. These considerations are illustrated by an analysis of the recreational activity of Szczecin residents and of tourists, and attempt identifying the relations between recreational space and tourism space. With the constant compression of leisure time, tourism activities become more similar to the leisure activities of residents, which means both types occur in the same environment. Urban recreational and tourism spaces overlap in a way that makes it impossible to separate them, but still allows the distinction of certain sub-spaces where either tourism or recreational behavior prevails.
Creative and Artistic Recreation and a Creative Approach to Recreation Organization: A Case Study of WI-MA Creative Industries Establishments
Authors: Mroczek-Żulicka Aleksandra 
Published: July 2018

AbstractArtistic recreation has been described in the literature for many years as one of its types. However, research into its meaning, or even motivation, is rarely undertaken. The author attempts to confront existing definitions of artistic recreation with changing trends in spending free time and types of recreational activity. She emphasizes the role of a creative approach to the organization of recreation as an opportunity for the better utilization of its potential to affect the development of the individual personality. To illustrate the values of artistic recreation and a creative approach to its organization, the author analyzes the case study of WI-MA Creative Industries Establishments.

Authors: Chernatska О. M. , Demikhova N. V. 
Published: July 2018

The aim of our one-stage observational study was the detail analysis of structural, functional, endothelial peculiarities of diabetic nephropathy in patients with coexistent arterial hypertension.
Methods. Our study involved 96people with arterial hypertension and type 2 diabetes mellitus (I group), 25 patients with arterial hypertension (II group), 15 practically healthy persons (III group) treated and obtained in Sumy City Clinical Hospital №1. Cardiovascular complications were determined in all patients from I and II groups. The average age of the patients was 62.31 ± 0.2 years. The level of glycosylated hemoglobin (HbAlc) was determined by the biochemical method, albuminuria by immunoassay. The level of endothelin-1 (ET-1) in serum was studied using ELISA.
Results. It was found that the level of ET-1 was significantly higher in patients with diabetes compared with only hypertensive patients. In the patients with urine albumin excretion rate category A2 the level of endothelin-1 was significantly higher compared with the category A1 patients and less compared with category A3 patients (11.42 ± 49 vs 25 ± 0.57pg/ml, p = 0.0329 and 11.42 ± 0.49 vs 2.25 ± 1.04pg/ml, p <0.0001, respectively. So, the level of ET-1 increased in proportion to albuminuria. In patients with the albuminuria category A2, the endothelin-1 level was higher than in subjects with the A1 category and lower than in patients with the A3 category. In addition, we identified a moderate direct correlation between the blood level of ET-1 in the patients with diabetes and blood glucose level (r = 0.29;p = 0.004).
Conclusion. Finally, it is the confirmation of greater endothelial function disorders for arterial hypertension and type 2 diabetes mellitus. In conclusion, endothelial dysfunction promotes diabetic nephropathy progression.

Our understanding of the richness and uniqueness of the flora growing on gypsum substrates in Italy has grown significantly since the 19th century and, even today, new plant species are still being discovered. However, the plants and plant communities, growing on gypsum substrates in Italy, are still a relatively unknown subject.
The main aim of this paper was to elaborate a checklist of the Italian gypsophilous flora, to increase knowledge about this peculiar flora and for which conservation efforts need to be addressed.
Through a structured group communication process of experts (application of the Delphi technique), a remarkable number of experienced Italian botanists have joined together to select focal plant species linked to gypsum substrates. From the results obtained, 31 plant species behave as absolute or preferent taxa (gypsophytes and gypsoclines) and form the ‘core’ Italian gypsophilous flora. The most abundant life forms were chamaephytes and hemicryptophytes, belonging to Poaceae and Brassicaceae; as for chorotypes, the most represented are Mediterranean and narrow endemics. By improving on previously available information about the flora with a clear preference for gypsum in Italy, this undertaking represents an important contribution to the knowledge of a habitat which is today considered a priority for conservation.
La dégénérescence de l’État-nation
Authors: Pierré-Caps Stéphane 
Published: July 2018

Depuis plus de deux siècles, l’État-nation s’est construit historiquement et juridiquement par l’association de deux formes de sociabilité humaine : une communauté de destin historique, d’une part, une société politique de citoyens, d’autre part. Ces deux formes agissaient l’une sur l’autre en une relation dialectique afin de former une société inclusive, ouverte sur le monde par sa capacité d’intégration. Il en résultait que la nation ne saurait être un donné , mais qu’elle était au contraire un construit , expression d’une volonté politique seule capable d’inscrire cette communauté singulière dans l’universalité des principes de l’État de droit. Or, nous assistons aujourd’hui au délitement de cette association entre la réalité nationale et son cadre d’action civique, en raison de la dénaturation de ses éléments constitutifs : le peuple politique se trouve instrumentalisé au profit de la domination sans partage d’une majorité politique, autrement dit d’une identification de cette dernière au peuple tout entier, identification à laquelle aspirent les mouvements populistes. La nation, sous les effets conjugués de la mondialisation, des mouvements migratoires et de l’affaiblissement de l’État social, se ferme sur sa source et son refus de l’Autre .

Authors: Warren Clinton C. , Young Jonathon B. , Goldberg Mara R. , Connor Thomas B. , Kassem Iris S. , Costakos Deborah M. 
Published: July 2018

BACKGROUND AND OBJECTIVE:
To determine whether retinopathy of prematurity (ROP) that persists beyond a postmenstrual age (PMA) of 45 weeks has abnormalities that can be documented by fundus photography or fluorescein angiography (FA).

PATIENTS AND METHODS:
Fundus photographs and FAs were reviewed for all premature infants who underwent FA for persistent ROP after 45 weeks PMA.

RESULTS:
Of the 487 infants who were screened for ROP, 16 (3.3%) demonstrated ROP beyond 45 weeks. Seven (43.8%) infants received prior treatment with intravitreal bevacizumab (IVB) for Type 1 ROP. FAs were obtained in eight cases; four subjects were previously treated with IVB. Leakage at the vascular-avascular border was demonstrated in seven subjects (87.5%). Shunt vessels, posterior retinal nonperfusion, and absence of the foveal avascular zone was limited to the IVB group.

CONCLUSIONS:
There are persistent vascular abnormalities among infants with ROP beyond 45 weeks. Findings that may be missed by RetCam fundus photographs were highlighted with FA.
