Perceptions of the resident of Santiago de Compostela regarding tourism: effects on hospitality

Abstract Santiago de Compostela is one of the best-known pilgrimage routes globally, and it connects many countries in Europe. Its historic center was recognized as a UNESCO World Heritage Site in 1985. This article aims to assess the types and quality of social interaction among residents and visitors (city users) of this particular World Heritage City. Many studies were conducted prior to this one about Santiago. However, most of them have missed some recent approaches to the overtourism phase. The “overtourism” is a phase, which was notorious until 2019. The primary sourcing was assessed by a quantitative study accompanied by a questionnaire responded by 588 residents. The results confirmed that those more exposed to tourism were the most critical of their relationship with the visitor. Thus, we confirm a direct relationship between the intensity of contact with the visitor and the negative perception of tourism. The results are helpful for local and regional planners to implement more collaborative and democratic planning in the tourism sector. This is more relevant to destinations recognized as UNESCO and revealed an overtourism scenario. This new approach is urgent and must be prepared in the on-going COVID-19 pandemic and a short and long-term perspective.
Identification, cultivation condition of Parasevetibacter sp C101 and antimicrobial activity of the bacterial culture extract

During the recent decade, uncultured bacteria have been special interest as potential candidates for discovering novel antibacterial compounds. Two strains C101 and C102 were negative Gram bacteria, only growing on low nutrient media as R2A/3, NB/3, LB/10 and R4/10 compared to the usual. On R2A/3 medium, colonies of the isolates were round, convex, lemon yellow color with the size of 1-1.5 mm after six days of incubation at 28oC. Cells were 0.2-0.3 × 0.8-1.3 µm. The strains C101 and C102 were able to grow at temperature ranging 15-37oC (optimum at 25-28oC), pH 5-8 (optimum in pH 6-7). The sequences of 16S rRNA genes from strain C101 (MT756087) and C102 (MT756088) shared 100% identity. Analysis of full-length 16S rRNA gene sequence of strain C101 via using NCBI Blast, EzTaxon Database revealed the highest similarity of 99.18-100% to uncultured clones, and 97.86% to type species as Parasegetibacter terrae SGM2-10T. Genetic sequence analysis data showed that strain C101 should be considered a novel candidate species of the genus Parasegetibacter. Antibacterial compound was extracted from culture of strain C101 in R4/10 medium for ten days of shaking incubator at 28oC and exhibited susceptible activity to inhibit Bacillus anthracis KEMB 211-146 at a concentration of 2 µg/L and Staphylococcus aureus ATCC 6538 at 4 µg/L; intermediate inhibiting Bacillus subtilis KEMB 51201-001 at 8 µg/L, Staphylococcus epidermidis ATCC 14990 at 8 µg/L, and S. aureus CCARM 3155 at 16 µg/L; inhibition of S. aureus CCARM 3095 at 64 µg/L, S. aureus CCARM 3192 at 32 µg/L, and S. epidermidis CCARM 3710 at 64 µg/L.
Adverse Effects of Bisphenol A on the Liver and Its Underlying Mechanisms: Evidence from In Vivo and In Vitro Studies

BPA is a known endocrine-disrupting agent that is capable of binding to the estrogen receptor and has exhibited adverse effects in many laboratory animal and in vitro studies. Moreover, it also been shown to have estrogenic, antiandrogenic, inflammatory, and oxidative properties. The widespread presence of BPA in the environment presents a considerable threat to humans. BPA has been shown to be leached into the human ecosystem, where it is commonly found in food products consumed by humans. Although the concentration is relatively low, its prolonged consumption may cause a variety of deleterious health effects. The liver is an important organ for metabolizing and detoxifying toxic metabolites to protect organisms from potentially toxic chemical insults. BPA that is ingested will be eliminated by the liver. However, it has also induced hepatoxicity and injury via various mechanisms. To find research demonstrating the effects of BPA on kidney, a number of databases, including Google Scholar, MEDLINE, PubMed, and the Directory of Open Access Journals, were searched. Thus, this review summarizes the research on the relationship between BPA and its effects on the liver-derived from animals and cellular studies. The underlying mechanism of liver injury caused by BPA is also elucidated.
HHI-AttentionNet: An Enhanced Human-Human Interaction Recognition Method Based on a Lightweight Deep Learning Model with Attention Network from CSI

Nowadays WiFi based human activity recognition (WiFi-HAR) has gained much attraction in an indoor environment due to its various benefits, including privacy and security, device free sensing, and cost-effectiveness. Recognition of human-human interactions (HHIs) using channel state information (CSI) signals is still challenging. Although some deep learning (DL) based architectures have been proposed in this regard, most of them suffer from limited recognition accuracy and are unable to support low computation resource devices due to having a large number of model parameters. To address these issues, we propose a dynamic method using a lightweight DL model (HHI-AttentionNet) to automatically recognize HHIs, which significantly reduces the parameters with increased recognition accuracy. In addition, we present an Antenna-Frame-Subcarrier Attention Mechanism (AFSAM) in our model that enhances the representational capability to recognize HHIs correctly. As a result, the HHI-AttentionNet model focuses on the most significant features, ignoring the irrelevant features, and reduces the impact of the complexity on the CSI signal. We evaluated the performance of the proposed HHI-AttentionNet model on a publicly available CSI-based HHI dataset collected from 40 individual pairs of subjects who performed 13 different HHIs. Its performance is also compared with other existing methods. These proved that the HHI-AttentionNet is the best model providing an average accuracy, F1 score, Cohen’s Kappa, and Matthews correlation coefficient of 95.47%, 95.45%, 0.951%, and 0.950%, respectively, for recognition of 13 HHIs. It outperforms the best existing model’s accuracy by more than 4%.
BRAND: Ultra-Wideband Feed Development for the European VLBI Network - A Dielectrically Loaded Decade Bandwidth Quad-Ridge Flared Horn

We present the design of an ultra-wideband dielectrically loaded Quad-Ridge Flared Horn (QRFH) feed for the European Very Long Baseline Interferometry Network (EVN) developed under the RadioNet project BRoad-bAND (BRAND). The feed covers a frequency bandwidth ratio of 10:1 and has an average aperture efficiency of 50 percent simulated in primary focus setup on the Effelsberg telescope (f/D = 0.3). The feed is dual-polarized and has an input reflection better than −10 dB over the whole 1.5–15.5 GHz frequency band. We also introduce an Analytic-Spline-Hybrid (ASH) optimization scheme for the QRFH ridge and sidewall profiles.
Psychometric Properties of the Persian Version of the Coping with Children’s Negative Emotions Scale

Background: Despite the importance of the parents’ role in socializing children, there is no specific tool in this field in Iran. The Coping with Children’s Negative Emotions Scale (CCNES) is a tool to assess the parents’ responses to children’s emotions. Objectives: This study evaluated the reliability and factor structure of a Persian version of the CCNES. Methods: This study assessed the psychometrics of the CCNES with 400 mothers after translation/back-translation and adaptation into Persian. Mothers were recruited if they had a child aged 3 - 6 years old, lived in municipal district 6 of Tehran and scored less than 25 in the General Health Questionnaire. Results: The results revealed the internal consistency and confirmed the test-retest reliability of the Persian version of CCNES. The exploratory factor analysis yielded a model with six-subscales. The Cronbach's alpha coefficients of the obtained factors ranged from moderate to good/very good: Distress Reactions (DR, 0.65), Punitive Reactions (PR, 0.80), Minimizing Reactions (MR, 0.80), Ignoring Reactions (IR, 0.8), Expressive Encouragement (EE, 0.84), Emotion-Problem Focused Reactions (EPFR, 0.88). Conclusions: According to the results, the Persian version of CCNES is a reliable and valid instrument for mothers to assess their responses to children’s emotions. Similar research is recommended for fathers.

This book presents methods of solving problems in three areas of classical elementary mathematics: equations and systems of equations of various kinds, algebraic inequalities, and elementary number theory, in particular, divisibility and diophantine equations. While this book emphasizes some methods that are not usually covered in beginning university courses, it nevertheless teaches techniques and skills that are useful not only in the specific topics covered here.
¿Cómo viaja la luz? La actividad experimental para desarrollar competencias científicas en la infancia

En México, en el nivel de primaria se espera que los estudiantes comprendan fenómenos físicos, entre los que se encuentra la luz y sus interacciones. Esto representa un desafío debido a que, durante la formación inicial docente, los contenidos alusivos a la física no están incluidos en el mapa curricular. Las implicaciones se observan en el aprendizaje de los estudiantes de este nivel, porque les es complejo explicar desde la perspectiva científica los fenómenos y procesos naturales. El objetivo de esta investigación fue analizar el nivel de logro de la competencia: comprensión de fenómenos y procesos naturales desde la perspectiva científica, mediante la aplicación de una actividad experimental relacionada con la trayectoria de la luz. Se trató de un estudio de caso, a través de un enfoque cualitativo. Los participantes fueron 59 alumnos de 8 a 10 años de edad que cursan el nivel de educación primaria. En los resultados se reconoce la necesidad de la actividad experimental para promover el desarrollo de competencias científicas en la infancia. La importancia de favorecer la reflexión de la observación para la construcción de explicaciones de lo que ocurre en el entorno y la construcción de significados para el conocimiento científico.
Role of AGN feedback in galaxy evolution at high-redshift

There is growing evidence that supermassive black holes may play a crucial role for galaxy evolution, in particular during the formation of massive galaxies at high redshift (z ~ 2 - 3). Our work focuses on quantifying the effects of jets of radiogalaxies and of large bolometric luminosities of quasars on the interstellar gas in their host galaxies. To this end, we studied the kinematics of the ionized gas in 12 moderately powerful radio galaxies and 11 quasars (6 radio-loud and 5 radio-quiet) at high redshifts with rest-frame optical imaging spectroscopy obtained at the VLT with SINFONI. We searched for outflows and other signatures of feedback from the supermassive black holes in the centers of these galaxies to evaluate if the AGN may plausibly quench star formation. In our sample of moderately powerful radiogalaxies, we observe velocity dispersions nearly as large as those observed in the most powerful ones (with FWHM ~ 1000 km/s), but the quantity of ionized gas is decreased by one order of magnitude (Mion gas ~ 10^8 - 10^9 Msun) and velocity gradients tend to be less dramatic (Δv < 400 km/s), when they are observed. In our sample of quasars, we had to carefully subtract the broad spectral component of emission lines to have access to its narrow, and spatially extended, component. We detect truly extended emission line regions in 4/6 sources of our radio-loud subsample and in 1/5 source of our radio-quiet subsample. We estimate that masses of ionized gas in these sources are smaller than in our sample of high-redshift radiogalaxies (with Mion gas ~ 10^7 - 10^8 Msun) and kinematics tend to be more quiescent, akin to what is observed in local quasars. Finally, detailed observations of two outliers among our sample of high-redshift radiogalaxies revealed that one of them is closely surrounded by 14 companions galaxies, hence lying in an overdensity. We therefore interpret the presence and morphology of ionized gas around these galaxies as evidence for repeated cycles ouf AGN outbursts, akin to what can be observed in local clusters of galaxies, which are prime examples of AGN feedback in the nearby Universe.
Using Extended Technology Acceptance Model to Assess the Adopt Intention of a Proposed IoT-Based Health Management Tool

Advancements in IoT technology contribute to the digital progress of health science. This paper proposes a cloud-centric IoT-based health management framework and develops a system prototype that integrates sensors and digital technology. The IoT-based health management tool can collect real-time health data and transmit it to the cloud, thus transforming the signals of various sensors into shared content that users can understand. This study explores whether individuals in need tend to use the proposed IoT-based technology for health management, which may lead to the new development of digital healthcare in the direction of sensors. The novelty of this research lies in extending the research perspective of sensors from the technical level to the user level and explores how individuals understand and adopt sensors based on innovatively applying the IoT to health management systems. By organically combining TAM with MOA theory, we propose a comprehensive model to explain why individuals develop perceptions of usefulness, ease of use, and risk regarding systems based on factors related to motivation, opportunity, and ability. Structural equation modeling was used to analyze the online survey data collected from respondents. The results showed that perceived usefulness and ease of use positively impacted adoption intention, Perceived ease of use positively affected perceived usefulness. Perceived risk had a negative impact on adoption intention. Readiness was only positively related to perceived usefulness, while external benefits were positively related to perceived ease of use and negatively related to perceived risk. Facilitative conditions were positively correlated with perceived ease of use and negatively correlated with perceived risk. Technical efficacy was positively related to perceived ease of use and perceived usefulness. Overall, the research model revealed the cognitive mechanism that affects the intention of individuals to use the system combining sensors and the IoT and guides the digital transformation of health science.
On the covariance of scan-matching techniques for localization

This paper considers the problem of estimating the covariance of the relative displacement measurement output by the Iterative Closest Point (ICP) algorithm. The problem is relevant for localization of mobile robots (using a sensor of the Kinect type) or for autonomous vehicles (using a sensor of the Velodyne type) where the relative displacement measurement must be fused with other sensors' measurements, such as wheel encoders or inertial sensors, in a Kalman or a particle filter. The closed-form formulas proposed in previous literature generally build upon the fact that the solution to ICP is obtained by minimizing a function of the data. In this paper, we prove this approach is on shaky ground because the rematching step of the ICP is not explicitly accounted for, and a blind application to point-to-point ICP leads to completely erroneous covariances. Yet we justify that the method is applicable to point-to-plane ICP as already known to practitioners, by proposing a geometric mathematical proof bounding the errors made.
Increasing Work Engagement Through Servant Leadership and Organizational Justice

Work engagement is important for teachers. Some factors that need to be considered by school management to improve work engagement are leadership practices and a climate of fairness in schools. This study aims to analyze how servant leadership and organizational justice practices affect the work engagement of permanent teachers at SMAK and SMKK in Cepu, Blora, and Rembang. Central Java. The research sample was 65 permanent teachers at SMAK and SMKK Cepu, Blora, and Rembang. The data analysis techniques used are simple linear regression and multiple linear regression, and the results showed that (1) servant leadership positively and significantly influenced organizational justice with a coefficient value of 0.655; (2) organizational justice positively and significantly affects work engagement with a coefficient value of 0.608; (3) Servant leadership does not significantly affect work engagement with a coefficient value of 0.009. The findings suggest that principals can select servant leadership practices to increase work engagement and build organizational justice, which includes distributive justice, procedural justice, and interactional justice.
Evolutionary characterization of clades 2.3.4.4 H5N6 and 2.3.2.1c H5N1 HPAI viruses in Vietnam (2013–2019) revealed distinct reassortants from distant spillovers

Highly pathogenic avian influenza (HPAI) H5Nx viruses have continually undergone multiple evolutionary dynamics for the generation of various clades, subclades, and genotypes where 2.3. 2.2c, and 2.3. 4.4 become predominant and co-circulating in Vietnam from 2014 to date. In this study, fifteen H5 sequences in our study and 90 from others from different clades, 0, 1, 1.1, 2.3. 2.1a, 2.3. 2.1c, 2.3. 4, 2.3. 4.1, 2.3. 4.2, 2.3. 4.3 and 2.3. 4.4 of H5N1, H5N2, H5N6, were characterized for hemagglutinin (HA) properties, genetic and phylogenetic analyses. Blast searching using the dataset of the full length of two H5N6 viruses revealed one strain, e.g., A/Duck/Vietnam/HT7/2014(H5N6) in May 2014, belonging to the Sichuan 2014-lineage of Group D (Minor). The other strain, A/Chicken/Vietnam/NT3/2017(H5N6)/or CkNT3-2017 in the Spring of 2017, belonged to the Japanese-Korean late 2016-cluster of Group C (Major). This cluster possessed 140NHETS-145del stretch of Leucine/Serine deletion at position 145 in HA1 (S/L145del), distinct from all the 2.3. 4.4 H5N6 viruses known to date. There has been no report of the similar CkNT3-2017 of 2.3. 4.4 reassortant in Vietnam prior to our study. The migration flyway might be the route for transportation of this novel H5N6 virus from Japan to Vietnam. In addition, the topology revealed another novel subclade of H5N6 (2018–2019) possibly, of the Vietnamese internal reassortments. The “H5Nx” viruses in Vietnam, in fact, have continually undergone multiple evolutionary processes in parallel with those lineages in China and East-Asia. Variations at the key sites in HA and altered genetic characteristics in novel HPAI H5Nx viruses in Vietnam present a caution for the vaccination program and the risk for human infection.
Environmental health enhancement by recycling poultry processing waste into protein ingredient in common carp Cyprinus carpio L. diets

This study was designed to investigate recycling poultry processing waste into protein concentrate as a step for supporting environmental health and resource sustainability, using it as a partial replacement of fish meal in diets prepared for common carp Cyprinus carpio L. fingerlings and explore its effect on fish growth, feeding efficiency and feed digestibility. Poultry waste was recycled into protein concentrate by a physical method, the chemical composition of this concentrate was analyzed, amino acid profile was determined, as well as the chemical composition of the prepared diets was analyzed. Four diets were prepared with substitution ratios of 0, 25 ,50 and 75% of fish meal with poultry waste protein concentrate. The results showed significant differences (P< 0.05) between the four experimental diets in terms of weight gain, specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and protein productive value (PPV). The treatment T3 (substitution rate of 75%) outperformed all other three treatments. No significant differences were observed between the studied treatments in the total apparent digestibility coefficients and the digestibility coefficients of different nutrients (protein, fat, carbohydrates and ash).
The Effect of Respiratory and Core Stability Tele-exercises on Pulmonary and Functional Status in COVID-19 Survivors: A Randomized Clinical Trial

Purpose: Various complications, including physical, cognitive, and functional disorders, have been identified in patients discharged and recovered from COVID-19. Pulmonary rehabilitation (PR) can be considered a strategy for these disorders. This study aimed to investigate the effect of respiratory and core stability tele-exercises on pulmonary function and functional capacity in survivors discharged and recovered from COVID-19. Methods: This randomized clinical trial study was performed in Qom Province, Iran, in 2021. Thirty discharged patients voluntarily participated in this study and were randomly divided into two groups of 15 patients. Eventually, 27 patients in two groups of exercise (13 patients) and control (14 patients) completed this study. The exercise group performed respiratory and core stability tele-exercise for 8 weeks. Before and after the exercise program, pulmonary function, including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC ratio, and six-minute walk test (6MWT) were assessed in both groups. Mixed repeated measures test in SPSS software v. 27, was used to compare the mean of pre-test-post-test information of the groups. The significance level for this study was considered 0.05. Results: In the exercise group, a significant improvement was observed in FVC, FEV1, and 6MWT after the intervention (P≤0.05), but no significant difference was observed in the FEV1/FVC ratio (P>0.05). Furthermore, a significant interaction was observed in 6MWD, FVC, FVC (predicted), FEV1, and FEV1 (predicted). However, in FEV1/FVC ratio, no significant interaction was observed between the two groups (P>0.05). Conclusion: The results of the study showed that in the new crisis resulting from persistent complications of COVID-19, respiratory and core stability exercises by the tele-exercise method could be used as a helpful method in the rehabilitation of patients discharged and recovered from COVID-19 disease.
