Use of Mobile/Tablet and Web-Based Applications to Support Rehabilitation After Stroke: A Scoping Review
Authors: Marwaa Mille Nabsen , Guidetti Susanne , Ytterberg Charlotte , Kristensen Hanne Kaae
Published: February 2022

Objective: To describe and review evidence of mobile/tablet and web-based applications to support the rehabilitation process after stroke. The secondary aim was to describe participants’ stroke severity, and use of applications in relation to, respectively, the setting and phase of the rehabilitation process.Methods: A scoping review methodology was used to identify studies, through databases such as Pub-Med, CINAHL, Embase and AMED. In addition, grey literature was searched. The studies were categorized according to Wade’s model of rehabilitation.Results: The literature search resulted in 12,065 records. Forty-six studies were included, in which applications were used to support: assessment (n = 16); training (n = 25); discharge from hospital (n = 2); and 2 studies were targeted at supporting discharge/education/information and training. One study targeted assessment, discharge support and goal-setting. No studies were related to the element “participation” using Wade’s model of rehabilitation. Of the 46 studies, 33 studies included participants with mild to moderate stroke, and 4 studies included participants with severe stroke. In 9 studies the stroke severity was not reported. Twenty three studies included participants with chronic stroke, 16 acute and/or subacute stroke, and 5 included participants with acute and/or subacute and/or chronic stroke. In 2 studies, stroke onset was not reported. Applications were used in a rehabilitation setting (n = 21), home setting (n = 17), and both settings (n = 3). In 5 studies the setting was not reported.Conclusion: Most studies of applications developed to support the rehabilitation process after stroke have been explorative. They primarily include participants with mild or moderate stroke and focus on a limited aspect of the rehabilitation process, e.g. assessmentor training. Future applications to support stroke rehabilitation should accommodate stroke survivors’ and significant others’ need for solutions, irrespective of stroke severity and throughout the entire rehabilitation process.
LAY ABSTRACTStudies have shown that the integration of applications (apps) can support the rehabilitation process after stroke. However, this scoping review found that most existing app solutions have limited usability, providing only 1 aspect of support in the rehabilitation process, such as clinical assessment or a narrow focus on exercises. Furthermore, currently available app solutions mainly target stroke survivors with mild stroke. Stroke survivors and significant others express a need for more comprehensive solutions to support the entire crosssectorial rehabilitation process. Therefore, there is a need for development of app solutions that support a greater part of the stroke rehabilitation process regardless of stroke severity.

The COVID-19 pandemic forced universities to engage in a transformation regarding how education is provided. The pandemic led to education being pushed in a new direction regarding digital practices. This paper discusses the implications related to this transformation by asking the following research question: After being subjected to the imposed and extensive use of online education due to the pandemic, what implications can be found when we examine pre-service teachers’ digital competence and attitudes towards and use of digital technology? This study is based on data from Norwegian pre- service teachers in their third year of an early childhood education program. Data was collected during the spring semester of 2020 and 2021. The data were subjected to regression and correlation analyses to investigate how the pre-service teachers’ use of technology, attitudes and digital competence may have been affected 10 months into this educational transformation. The main difference found between the two groups of preservice teachers is related to their attitudes and how these attitudes relate to the use of digital technology. Our findings indicate the importance of not neglecting attitude as an important component of professional digital competence. Attitude seems to be the component that is most affected by pandemic- related consequences for education, when looking at the dynamics between use of technology, professional digital competence and attitudes.

Many underlying physiological changes occur with age, and in elderly people, there is an increased risk of chronic disease and care dependence. Globally, the number of elderly people increases considerably in a relatively short period of time and the need for further support is also increasing exponentially. As the number of elderly people continues to grow along with their longevity, the need for long-term health care will increase significantly. Ultimately, the health care system faces a number of challenges, including long-term care, which includes activities related to the risk of age-related disabilities associated with chronic diseases.
We examine the status of the elderly program in Oman, the achievements, and gaps in achieving the Ministry of Health's vision in 2050.
The review eluded that the elderly program is headed in the right direction, however, the program still has unmet needs of physical fitness-related care, psychological health care, community support, and the leaving the environment. The findings of this review also underlined the importance of care models and support services specifically based on the needs of the elderly.

It is shown that the experimental studies of flame propagation speed, the maximum pressure of the explosion of hydrogen-air mixtures were carried out in free space under the influence of slowing down and accelerating factors, such as power and type of ignition source, the effect of flame acceleration in the pipe, the effect of obstacles on the flame propagation path, the volume and composition of the combustible mixture when the content of the oxidizing agent or phlegmatizer changes in it. The dependence was established allowing to estimate the volume of a hydrogen-air mixture, during the combustion of which one can expect the burning speed that is close to the speed of sound in the initial mixture, and at which the transition of deflagration combustion to detonation is possible. When phlegmatizing hydrogen-air and oxygen-hydrogen mixtures with inert gases, such as nitrogen for example, the effect of reducing the burning speed and explosion pressure is achieved. The processes and conditions for the transition of deflagration combustion to detonation of free volumes of hydrogen-air mixtures and mixtures enriched and depleted of oxygen, depending on the power of the ignition source, volume, composition of the mixture and its turbulence, were studied. It is noted that as the content of the inert gas in the mixture increases, these indicators decrease, and the profile of the pressure wave changes qualitatively. Turbulization of hydrogen-air and hydrogen-oxygen mixtures with dilution using nitrogen to certain limits by turbulators leads to an increase in the values of the apparent burning speed and the maximum speed of explosion burning, up to the transition to detonation. Irrigation of combustible mixtures with atomized water leads to the same effect.

The aim of this study was to evaluate the concentration, progressively motile, and percent live sperm in the various regions of epididymis and ductus deferens after preservation at 4oC. Epididymis and ductus deferens were collected from 21 epididymis and ductus deferens of domesticated cat (Felis catus) by castration. One testicle of pair (control testicle) was analyzed at the day of castration, while the other testicle of the pair was stored at 4oC up to 7 days. The sperm concentration, percentage of sperm motility and live sperm were examined daily until day-7 of preservation. The sperm concentration was higher (p<0.05) in cauda epididymis (23.99x106 sperm/ml) and ductus deferens (25.42x106 sperm/ml) than caput (11.51x106 sperm/ml) and corpus epididymis (14.82x106 sperm/ml). The percentage of sperm motility and live sperm decreased (p<0.05) during preservation period. However, the percentage of motile (11.33 to 16.00 %) and live (15.05 to 20.20 %) sperm could be found in preserved epididymis and ductus deferens up to day-7. These results show that motile and live sperm can be collected from cat’s epididymis and ductus deferens up to day 7 after preservation at 4oC.

The experiment aimed to detect (1) mycorrhizal infection induced phytoalexins production of the root of tusam and (2) its activity in suppressing a dumping off fungi, Fusarium sp and Rhizoctonia solani. Production of phytoalexins was detected from the extracts of mycorrhizal root of old trees and 4, 6 and 8 week-old seedlings in alcohol using a UV-spectrophotometer. The antifungal activity of phytoalexins was studied by inoculating the pathogenic fungi into mycorrhizal seedlings of tusam. The results showed that the spectra of phytoalexins of extracted mycorrhizal and non-mycorrhizal roots ranged from 203.2 to 204.6 nm. Higher antifungal concentrations of antifungal compound was obtained from the root extracts of old trees and 4 week-old seedlings, indicated by the higher spectrophotometric absorbance (0.315 and 0.324 g-1 root ml-1 ethanol), compared to that extracted from non-mycorrhizal root of the same plant origin. Mycorrhizal roots significantly suppressed the development of Fusarium sp. and Rhizoctonia solani.

High fat and low fiber dietary pattern results in raising of blood cholesterol level over the normal level, namely hypercholesterolemia. Hypercholesterolemia might cause coronary disease and stroke. Blood cholesterol is able to be decreased by probiotic supplement. Lactobacillus is one of the probiotics that were well known and taken advantages. However its role as cholesterol lowering agent was less known. Therefore, screening and identification of Lactobacillus isolates which were candidates of probiotic have been carried out. Isolates Mar 8, Lac 3 and 7 p have been selected as Lactobacillus candidates for cholesterol lowering probiotic. Those isolates met criteria for cholesterol lowering probiotics. Furthermore, they have been conducted to confirm their identity as Lactobacillus. 16S RNA sequences analysis by BLAST analysis against reference strains within DNA Data Bank of Japan (DDBJ) have been carried on. Results showed that sequences of Lactobacillus Mar 8 was 100% homology with Lactobacillus plantarum, Lac 3 was 100% homology with Lactobacillus paracasei and 7 p was 99% homology with Lactobacillus plantarum. It was concluded that the three isolates were selected as candidates for cholesterol lowering probiotics. Both of them, Mar 8 and 7 p, are Lactobacillus plantarum. Another one, Lac 3 is Lactobacillus paracasei.

Published: February 2022

Polymerase chain reaction (PCR) is a technique of DNA amplification which its success depends on the wider range of several factors, e.g., the annealing temperatures and MgCl2 concentrations. The aim of this study was to determine the effect of annealing temperatures and MgCl2 concentrations on the amplicon specificity of CSSM018 primer. Annealing temperatures of 50oC to 60oC were used in this study while MgCl2 concentrations were in the range of 1.0mM to 2.5 mM. DNA genome of Garut sheep was used as DNA template. PCR products were visualized by a method of 8% ND PAGE. The findings showed that the annealing temperature of 60oC presented the most specific band of the CSSM018 primer at the right size of 116-134bp. Annealing temperatures that were less than 60oC showed the weaker and non-specific bands. A concentration of 1.25 mM MgCl2 showed the best band of the CSSM018 primer with size of 116-134bp. While concentrations of 1.5; 1.75; 2.0 and 2.5 mM MgCl2 showed sharper with some bands seemed noisy, those indicated non-specific products. This study suggests that annealing temperature of 60oC and MgCl2 concentration of 1.25 mM resulted specific amplicon for CSSM018 primer.

Soil pollution by substances such as benzene can cause serious problems such as aquifer contamination and reduction of the biodiversity of organisms. A number of microorganisms are capable to degrade such substances naturally. However, introduction of any other microorganisms and or nutrient (bioaugmentation) are necessary in order to improve the biodegradation rate. This study examined the effect of introducing promising local strains of Bacillus namely U41 and U44, and urea addition at concentration 0.25% w/v. The parameter measured was benzene, pH, microbial number, and CO2. The best result was revealed from bioaugmentation of mixture of U41 and U 44. However, that result was not significantly difference with the use of single either strain U41 or U44, respectively.

Published: February 2022

New critical educational issues arose during the implementation of distance education in the COVID-19 period. One of the most serious was the lack of non-verbal communication between students and teachers during distance education, as the physical contact of teaching was "mediated" by the digital environments of synchronous and asynchronous education. In this paper, we first describe and then take the first steps to fill this gap by designing non-mandatory descriptive methods for distance communication. To achieve this, we use conceptual representations and examine material by the real participation of Vocational Education and Training students in synchronous and asynchronous online environments. We present examples of verbal and non-verbal communication from student participation, using specific online applications, namely Mentimeter.com Hot Potatoes, and Wonder.me. Moreover, through the overall analysis of the issue, we illuminate the dynamic changes in the field of education, both due to the digital transformation of the institutional structures and to the change in attitudes and characteristics of students that result from these transformations.

The article presents the results of the newest research performed by the State Enterprise «Ukrainian Geological Company» and the Institute of Geophysics of the National Academy of Sciences of Ukraine in 2021 to find out the morphology and elements of occurrence of an redeposit within the limits of the Gorishne-Plavninsk-Lavrikovsk area of the Krivoy Rog-Kremenchug iron-ore strip. In the process of geological and geophysical studies, a large body of new geological and geophysical data was obtained regarding the deep structural and morphological features of the construction of the Gorishne-Plavninsk structure (GPS), associated with the Krivoy-Rog deep fracture zone.

Materials of reinterpretation of previously per formed ground-based magnetometric and gravimetric surveys, detailed high-altitude aeromagnetic studies and the study of the density and magnetic properties of the structure rocks, including the anisotropy of magnetic susceptibility using new equipment and techniques, gravimagnetic modeling with the construction of three-dimensional volume model of the structure lead to the conclusion that this structure is a typical drag fold with a pronounced reversal of its southern part by the right-hands hear. Its primary formation occurred as a faulted band of sedimentary-volcanogenic and extrusive formations of subvertical bedding and spreading to a depth of at least 1.5—2 km.

A complete morphological and kinematic analogue of the GPS is the previously studied Likhmanovsk structure, located in the southern most part of the Krivoy Rog-Kremenchug strip. Many iron-ore structures of the Middle Bug area are close to it in structure and kinematics, the primary subvertical faulting and doubtful sedimentary genesis were mentioned earlier. All these data require a new approach to the study of iron-ore and some other deposits of the Ukrainian Shield associated with fault tectonics, as well as to the genesis problems and stratigraphy of rocks of the Early Precambrian.

Published: February 2022

The paper presents the results of studying the lubricity of several lubricating compositions, two of which contain an antiwear additive based on a layered friction modifier - molybdenum diselenide. Oil MC-20, which does not contain functional antiwear additives, is used as a base lubricating medium and an object of comparison. Two variants for combining an antiwear additive with this oil differ in the process of initial preparation of the additive before adding it to the base lubricating oil by rotary pulsation grinding and stirring. Antiwear tests are arranged in the form of a consistent tribological rating of the given types of lubricating media at various operating time of the friction path of the test samples. The test tool is a rotary-type friction machine of an original design. There are analyzed the differences in the antiwear test methodology and the advantages of the proposed scheme over the analogous one, which is relevant for GOST R 51860-2002. Among the results of the tribological study carried out, topographic patterns of wear of test specimens, the dependence of the wear rate of tribological surfaces on contact pressures, and the dependence of the wear scar diameter on the amount of specimen wear are given. The antiwear additive has been found to contain a layered friction modifier of selenium dichalcogenide (molybdenum diselenide) type, it improves the lubricating film on friction surfaces and reduces their wear compared to the use of nonadditive oil MS-20. The wear degree of a stationary ball-shaped specimen when testing a lubricating medium with the antiwear additive is reduced by 66-85% compared to a base lubricating oil without additives. The diameter of the wear spot on a stationary specimen under these test conditions is reduced by 28-67%, which proves the effectiveness of preliminary preparation by rotary-pulsation mixing of a lubricant composition with a solid suspended base even with a relatively short preparation time.

Published: February 2022

Habitat types are closely associated with altitude gradients in tropical rainforests and play an essential role in species assemblages where terrain heterogeneity is often used to understand effects of climate change on species distribution. The response of larger mammals to habitat variation along altitudes is largely unexplored in Borneo. This study has utilised camera traps to better understand the community structure of larger mammals in Gunung Pueh National Park. Gunung Pueh National Park (1550 m a.s.l.) contains two major habitat types, which include lowland forests (< 1100 m a.s.l.) and the lower montane (> 1100 m a.s.l.) forests. The spatio-temporal niches of mid-sized to large-bodied mammal species across these altitude gradients and habitats were assessed. Cameras located at 23 locations, along varying altitude gradients, resulted in 3109 trap nights. Using these cameras, the collected recordings have revealed a total of 22 mid-sized to large-bodied mammals, including 19 species recorded in lowland forest areas, and 18 species in the lower montane forest areas; 15 species were found in both habitats. Four species were exclusively detected in the lowland forest, namely Rusa unicolor, Viverra tangalunga, Presbytis chrysomelas, and Hystrix brachyura. Three species were detected only in the lower montane forest, namely Herpestes semitorquatus, Mustela nudipes, and Hemigalus hosei. In the lowland forest, Macaca nemestrina was recorded with the highest naïve occupancy (naïve ψ = 1.00), while Hemigalus derbyanus had the highest naïve occupancy (naïve ψ = 0.93) in the lower montane forest. The temporal diel activity patterns of selected species in the two habitats have shown relatively close similarities, with overlapping patterns ranging between 67–90%. The further conservation of a large area, which encompasses mountainous ranges, is recommended to facilitate the conservation efficacy of such Protected Areas and for supporting diverse, mid-sized to large-bodied mammals in Borneo.
Urban Structure as a Precondition of Regional Development. Evidence from Slovakia
Authors: MARIS Martin , KOVACIK Marian
Published: February 2022

The main objective of the paper was to investigate a possible link between the urban structure and regional economic performance in Slovakia, at district level (LAU1). Based on the selected urban indicators, we identified distinct patterns in terms of urban structure and economic performance in Slovakia through the Agglomerative Hierarchical Clustering (AHC) method. The “inner” urban pattern includes districts located predominantly in the central part of the country with some extension to the west and east. Common characteristics of this pattern are higher centrality, clustering, and monocentric urban cores. The “outer” urban pattern includes districts located predominantly at the periphery, along the borders. The common characteristics of this pattern are the dispersed urban patterns and polycentric settlement structures. The underlying urban structure was matched with the economic conditions prevailing in each district for evaluating the degree of concordance. The kappa coefficient of concordance has shown a scant relation between the urban structure and economic performance of regions at the district level (LAU1). According to the main findings, underlying urban pattern (clustered or dispersed one) in any particular district does not preclude economic success or failure of its regional economy.

Published: February 2022

El presente estudio reúne un grupo de cuentas de collar oculadas halladas en la región suroeste de la Meseta Norte, fechadas en su mayoría a partir de mediados de la Edad del Hierro (ss. V-IV a.C.). Se trata tanto de viejas y conocidas piezas, como de nuevas e inéditas, con la intención de analizarlas en conjunto para saber cómo, cuándo y por dónde llegaron a los distintos yacimientos prehistóricos de las actuales provincias de Salamanca y Ávila. Para ello, se ha establecido una comparación con otras cuentas oculadas halladas en asentamientos de la Península Ibérica y las Islas Baleares, extrayendo algunas conclusiones sobre la importación de materiales, el intercambio entre comunidades y la herencia de la influencia mediterránea en la zona.
A győri bencés gimnázium második államosított tanéve és a szerzetesek visszatérése
Authors: Sárai-Szabó Kelemen , Dömötör Mihály

A második világháború lezárását követő koalíciós években az egyre fokozódó szovjet nyomásgyakorlásnak és a kommunista párt befolyásának növekedésével mindinkább szűkült az egyházak és különböző felekezetek társadalmi mozgástere. A kiformálódó új hatalom a katolikus egyházat és azon belül a szerzetesrendeket titulálta fő ellenségnek, amelyek működésének ellehetetlenítésére fokozatosan vezettek újabb és újabb intézkedéseket. Már a nagybirtokrendszer 1945-ös államosítása is alapjaiban rengette meg a különböző szerzetesrendeket, hiszen működésük és intézményeik ellátásának anyagi alapjai rendültek meg ezzel és kerültek egycsapásra az államtól függő anyagi helyzetbe, erősítve így kiszolgáltatottságukat. A koalíciós éveket követően 1948-tól teljesen világossá vált, hogy az ország társadalmi, politikai- és gazdasági berendezkedését a szovjet mintára kiépülő kommunista diktatúra és az azt fenntartó nomenklatúra által meghatározott keretek fogják megszabni. 1948 nyarán megtörtént az ország oktatási intézményeinek jelentős hányadát kitévő egyházi fenntartású iskolák államosítása, új állami tantervek kidolgozása, amely folyamatnak a győri bencés gimnázium is áldozatul esett. 1948 szeptemberében az intézmény Állami Czuczor Gergely Általános Gimnázium néven kezdte meg a tanévet és lett két évig ezáltal a város egyik szekularizált oktatás intézménye. Az államosítás folyamatának és az első tanévet követően e tanulmányban a második „államosított” tanévet tekintjük át, valamint az 1950-es év történéseit, amikor a gimnázium fenntartása újra visszakerült a magyar bencés rendhez. E két év során úgy tűnt, hogy a bencés gimnázium csak egy üde színfolt marad Győr történelmének palettáján, azonban a történelmi fejlődés másként alakította a folyamatokat és a győri bencés gimnázium továbbra is Győr és az ország meghatározó keresztény oktatási műhelyévé tudott válni. A győri gimnázium példájából továbbá fel tudjuk vázolni azokat a bel- és kultúrpolitikai technikákat is, melyeket a pártaállam az egyházak visszaszorításában és intézményeik, javaik államosítása során alkalmazott.

Aims

Postoperative pneumonia (POP) after redo cardiac surgery is prevalent, associated with poor outcome. The aim of this study was to identify independent risk factors for POP after redo cardiac surgery and to develop and validate a prediction model.

Methods

Adults undergoing redo cardiac surgery from 2016 to 2019 were identified in a single-institution database. Using a 2: 1 ratio, the patients were randomly divided into training and validation sets. Univariate and multivariate analyses were applied to identify independent predictors for POP in the training set. A nomogram model was constructed for clinical utility and was validated in the validation set.

Results

POP developed in 72 of the 376 patients (19.1%). Four independent risk factors were identified, including age, chronic obstructive pulmonary disease, serum creatinine level and intraoperative blood transfusion volume. A nomogram based on the four predictors was constructed, with good discrimination in both the training (c-index: 0.86) and validation sets (c-index: 0.78). The model was well calibrated, with a Hosmer-Lemeshow χ2-value of 7.31 (P 
= 0.50) in the training set and 7.41 (P 
= 0.49) in the validation set. The calibration was also good by visual inspection. The decision and clinical impact curves of the nomogram indicated good clinical utility. Three risk intervals were identified based on the nomogram for better risk stratification.

Conclusion

We developed and validated a nomogram model for POP after redo cardiac surgery. The model may have good clinical utility in risk evaluation and individualized treatment to reduce adverse events.

Radioisotope applications in industrial process inspection and evaluation using gamma-ray emitters provide otherwise unavailable information. Offering alternative gamma-ray sources can support the technology by complementing sources’ availability and radiation safety. This work proposes to replace gamma-ray from radioisotopes with prompt gamma-ray from the interaction of neutrons with stable isotopes injected into the industrial process or with the structural material of the industrial process equipment. Monte Carlo N-Particle Transport Code (MCNP5) was used to simulate the irradiation of two-phase flow pipes by 252Cf neutron source. Two simulations were run for each pipe, with and without mixing the liquid phase with the stable isotope 157Gd. The detected gamma-ray spectra were analysed, and images of the two phases inside the pipes were produced. The images were compared to images obtained from simulations of gamma transmission measurement using 60Co. Furthermore, results for prompt gamma computed tomography (CT) were presented and discussed. The studies’ outcomes indicate the potential of prompt gamma-ray to carry out the sealed sources applications of gamma transmission measurements and imaging.

Published: February 2022

Among the practitioners as well as among the researchers in the field of management, the theme of leadership enjoys a boundless and special interest. Regarding the results of the management within the SMEs, a very important role is played by the management. The aim of this paper is to examine the relationship between organizational commitment and the leadership dimensions of Bass (1985) (transactional, transformational and laissez faire) but also several outcome variables (leadership efficiency, employee satisfaction with the leader, additional effort employees). According to the methodology and approach, this is a systematic review of the literature. This review describes the Full Range Leadership Model (Bass, 1985) and the conceptual framework, which include laissez-faire leadership, transactional leadership, and transformational leadership. In this section, the characteristics and abilities of transformational leaders were discussed. The leadership section concludes with discussions of previous research on transformational leadership. This review also provides an analysis of the literature on organizational engagement. The various definitions of organizational commitment as well as the three components of the commitment model are set out. The paper presents the results and antecedents of organizational commitment resulting from previous research and concludes with a discussion related to the impact of transformational leadership on the organizational commitment of employees.

The COVID 19 pandemic has hit the world unexpectedly, generating a number of effects at the states level that have required rapid and effective reactions from them. The public sector was affected, with all its institutions, but equally the private sector. Under these conditions, the states had to adapt quickly to the new conditions generated by the pandemic with the novel coronavirus, by making decisions at the governmental level, designed to combat the health negative effects but also to ensure the efficient functioning of public sector institutions, so as to reduce negative effects on their citizens. A particularly important role in managing the crisis caused by the COVID 19 pandemic is played by the supreme audit institutions, the "guardians of public finances", as known these institutions. This paper aims to analyze the role and effectiveness of the supreme audit institutions at the level of public sector in the context of the global crisis generated by COVID 19 and their adaptation to new conditions.

We live in a time when the online presence is much better observed than the real presence. To this way of life is added the pandemic that has strongly affected the lives of all of us and has restricted, more or less, our free movement and freedom to be tourists. From the establishment of social platforms until recently, the focus has been on the individual and less on products, services or cities. Currently, a company or city does not exist if it is not found by users of social platforms within the applications. A city becomes attractive from a tourist point of view if it has "Instagramable" places. These places can be defined as areas inside the city that have certain characteristics that attract the tourist and make him take photos and upload those pictures on social networks. These areas are called "Instagram spots" and represent a new type of city way of marketing. We can see, in specialized practice, cities that did not exist a few years ago, but due to the increase in the number of users on Instagram, the increase in the number of photo posts in that city and a much larger activity due to the pandemic, they have become real tourist attractions. Through this paper we wanted to highlight this concept of "Instagram spots" and the importance it has in achieving the brand of a city. For this we will conduct a research based on a questionnaire applied to a number of 370 people active on social networks, but also an analysis of things that can be done using Instagram and we will try to establish a link between social networking users and the attractiveness of a Town. We will also try to determine the impact that these "Instagram spots" have on the cities where they exist and we will try to establish a link between the total number of these places, the number of tourists and the brand of the city.
