Photographic expeditions: interests and destinations in Perú

La crisis por el covid-19 ha dado la oportunidad al sector turismo de replantearse y ver al turista nacional con otros ojos, permitiendo que el sector sea mejor, más sostenible, inclusivo y resiliente. El estudio tuvo como objetivo identificar las preferencias y hábitos de viaje de turistas nacionales durante la pandemia, Perú, 2021. El estudio realizado fue de tipo básico, basado en un diseño no experimental transversal-exploratorio con enfoque cuantitativo. Se optó por un muestreo no probabilístico por conveniencia por conveniencia e intencional, estando la muestra conformada por 42 turistas nacionales. La técnica utilizada fue la encuesta y como instrumento el cuestionario. Los resultados señalan que el 53% considera importante realizar turismo, el 24% como algo importante. Asimismo, el 69% considera importante elegir un destino de naturaleza y al aire libre, el 38% uno de sol y playa. Para el 57% realizar actividades de aventura, el 67% considera importante la seguridad ciudadana en el destino y el 71% la limpieza. Se evidenció que la seguridad ciudadana es el atributo del destino más valorado e incluso al número de contagios que existe. Finalmente, las preferencias y hábitos de viaje de los turistas peruanos han cambiado y los desafíos para el sector radican en la capacidad de adaptación y reinvención orientados en los nuevos requerimientos del consumidor.The covid-19 crisis has given the tourism sector the opportunity to rethink and see the domestic tourist with different eyes, allowing the sector to be better, more sustainable, inclusive and resilient.

Loyalty to world heritage cities: a case study of the historic Ibn T. ul¯ un Mosque in Cairo (Egypt)

The city of Cairo is famous worldwide for its distinct heritage sites. Its uniqueness, its call effect, and its history are significant. So, it is essential to improve its management of tourism. The main objective of this research is to analyze the satisfaction of visitors to historic mosques in the context of heritage tourism. The study focuses on tourist loyalty from several perspectives: expectations, satisfaction with the city itself and satisfaction with the mosque. The fieldwork was carried out in Cairo (Egypt), specifically in the Ibn Ṭūlūn Mosque. It is more than 2000 years old and is considered the oldest mosque in Cairo and one of the most amazing mosques in the world. There are few studies on mosques from a tourism perspective, which makes this study innovative and a substantial contribution to the literature. The methodology used was based on partial least squares (PLS) structural equation modeling. A structured questionnaire was used to achieve the proposed objective. The results obtained confirmed that satisfaction during their visit to the Ibn Ṭūlūn Mosque positively influenced tourists’ loyalty, and therefore they recommended revisiting it

Influence of the pulp of Mangifera indica and Myrciaria dubia on the bioactive and sensory properties of ice cream

Ice cream is a widely consumed product in the world. Unfortunately, its standard presentation is very poor in nutraceuticals; fruits such as Mangifera indica and Myrciaria dubia have an important bioactive potential, which can be used to enrich this type of product in phytochemicals. However, maintaining the health and sensory aspects of a functional ice cream is still under investigation. The influence of Mangifera indica and Myrciaria dubia pulp on the bioactive and sensory properties of ice cream was studied. Four ice cream treatments were prepared with Mangifera indica (15% and 20%) and Myrciaria dubia (5% and 10%). Ascorbic acid content (reduction of 2,6 dichlorophenolindophenol), total phenolic content (Folin-Ciocalteu reaction) and antioxidant capacity (DPPH radical inhibition) were evaluated in addition to a sensory sorting test. The treatments with 10% Myrciaria dubia showed the highest ascorbic acid contents (83.46 and 71.27 mg/100g), total phenolic compounds (80.10 and 79.06 mgGAE/100g) and antioxidant capacity (61.0 and 64.05 mg ice/ml solvent) compared to the 5% treatment and the control; while the influence of Mangifera indica on these parameters was relatively minor. However, sensory evaluation showed that T3 (5% Myrciaria dubia; 20% Mangifera indica) were the most preferred, outperforming the control ice cream. It is evident that Myrciaria dubia stands out for its high ascorbic acid content, total phenolic compounds and antioxidant capacity of the ice cream while Mangifera indica improves its sensory aspect, allowing an overall balance of sweet-acid taste pleasant to the consumer and maintaining its health properties

Efecto de las células madre mesenquimales del tejido adiposo en la reparación del hueso alveolar después de la extracción dental

En España la media de dientes ausentes en la población de 35-44 años es de 1.40 y en la población de 65-74 años con al menos 21 dientes funcionales asciende a 44.3%, siendo un problema generalizado, inclusive en muchos países de Latinoamérica como Perú, donde cerca de medio millón de dientes se extraen anualmente (Llodra, 2012) La resorción ósea alveolar tiene varias causas: la extracción dental, trauma, periodontitis moderada a severa y fuerza continúa en el tratamiento ortodóntico. Todo ello conlleva a un posible fracaso de la prótesis e implante dental y un desequilibrio en la oclusión y la salud bucal, alterando inclusive la autoestima de las personas. Diversas investigaciones (Meruane y Rojas; 2010) han demostrado que las células madre mesenquimales del tejido adiposo (CMMTA) desempeñan un papel relevante en la reparación ósea, sin embargo, no hay suficiente evidencia sobre sus efectos en el hueso alveolar después de la extracción dentaria. En este trabajo he desarrollado un modelo experimental en rata para observar los posibles efectos de las CMMTA en el alveolo después de la extracción dental.Departamento de Biología Celular, Histología y FarmacologíaMáster en Investigación en Ciencias de la Salu

Preferences of sports tourism consumers

Background: There are few studies about consumer preferences in sports tourism, especially in Peru. The objective of the study was to identify consumer preferences for sports tourism modalities and to analyse the characteristics of students who engage in this activity. It involved 260 student volunteers from a population of 343 students at the Faculty of Hotel Management and Tourism at the National University of Frontera, Sullana, Peru. An open and closed questionnaire was applied to the participants and frequency tests were used for data analysis. The result indicates that 30% of the students prefer mountaineering, 18.5% prefer volleyball, and 16.5% prefer soccer to other sports tourism modalities. 21.5% and 32.3% of students preferred to spend one and two days respectively in the sports destination. In addition, 44.6% of the students identified themselves as sport vacationers and 38.8% spent less or equal to S/. 100.00 soles when traveling to their tourist destination. The majority of participants used the internet and social networks to plan and share their travel experience. Conclusions: Students of tourism prefer mountaineering and do not identify themselves as passive or active sports tourists, but rather as sports vacationers

Level of physical activity of Peruvian university students during confinement

Physical activity contributes to the health and well-being of students because of the physical, psychological, and social benefits it provides (especially during confinement). The objective was to identify the level of physical activity of college students during confinement by COVID-19. It is a descriptive and cross-sectional study conducted from March to July 2020. A population of 931 students enrolled in the Universidad Nacional de Frontera, Sullana-Peru, and a sample of 270 participated. The international physical activity questionnaire (IPAQ) was used. Of the total participants, 32% were men and 68% women, 51% resided in urban areas and 49% in rural areas. The level of physical activity was low in 20% of the students, moderate in 29% and high in 51% of the students respectively. Of the total, 13% were diagnosed with COVID-19, of which 2.6% had low levels of physical activity, 5.2% moderate and 5.5% high. 28.1% of the students had physical complaints associated with COVID-19 symptoms. It is concluded that during the confinement, the university students presented a high level of physical activity, mostly women from rural areas rather than urban areas, where the level of physical activity was low

Antimicrobial and production of hydrolytic enzymes potentials of bacteria and fungi associated with macroalgae and their applications: a review

Endophytic and epiphytic bacteria and fungi that live in association with macroalgae produce compounds that favor the growth of the host, being in some cases more efficient than those produced by the terrestrial microbiome. This review collects information from articles published in Scopus, ScienceDirect, PubMed, and Wiley Online Library. Articles were organized according to their antimicrobial properties, synthesis of hydrolytic enzymes, production of other bioactive compounds by bacteria and fungi, and their application. The information collected showed that bacteria and fungi associated with macroalgae have the ability to inhibit bacteria, fungi, yeasts, and protozoa that affect aquaculture, public health, and the food industry, reporting that the pyrenocines A, B, E, and S isolated from Phaeosphaeria sp. Inhibited pathogenic protozoa. Additionally, other compounds identified as alkaloids, steroids, triterpenoids, and flavonoids could act by altering the morphology and physiology of pathogenic microorganisms, which can be applied in the food, pharmaceutical, paper, chemical, textile, and cosmetic industries. In addition, these microorganisms can synthesize enzymes such as xylanase, amylase, cellulase, pectinase, agarase, lignocellulose, chitinase, gelatinase, asparaginase, glutaminase, and lipase, which can be used to reduce oxidation and enzymatic browning, improve digestibility and functionality of feed, synthesis of chitin oligomers with antimicrobial properties, bioremediation of agricultural residues and industrial effluents, and production of hydrolysates
