Authors: Ahmed Ali H. , Obaid Abbas Hassan
Published: March 2022

This study was conducted to investigate the lateral behavior of inclined anchored pile group by using (3 pile) model embedded in sandy soil by relative density 65% under lateral static load. The distances used between the piles are 60 mm which represents (3) Dh (helix diameter), noting that the diameter of the pile is 10 mm. The types of piles used are three types, and they are a pile with a single helix, a pile with a double helix and a pile without a helix (ordinary pile), noting that the depth embedded in the soil of piles (L/d) 330 mm. The angles of inclination used in this study are (5°, 10°, 15°). The results showed that increasing the angle of inclination of the pile leads to a higher amplitude of the lateral resistance of the pile group, the side resistance of pile with a single helix increase to about (9% and 18%) upon inclination angle increase from 5° to (10°,15°) respectively. While piles with double and single helix in the groups in same angle of inclination which is (10°) increases the lateral resistance from ordinary pile (pile without helix) about 24% and 19% respectively

Authors: Hameed Yahya
Published: March 2022

This investigation focuses on the impact of the concrete elimination ratio on the structural behavior of bubbled reinforced self-compacting concrete (SCC) slabs. Construction and testing of eight bubbled slab specimens with dimensions of 45x45x80mm are part of the experimental program. The specimens are separated into two categories. The first set of four specimens is used to explore the effect of removing regular strength SCC from concrete, while the second group is used to investigate the effect of removing high strength SCC from concrete. According to the results of the experiments, increasing the number of balls in a typical strength SCC reduces the first fracture load from 8.3 % to 15.5 % and the ultimate load from 3.98 % to 12.15 %. The experimental results indicated that the change of No. of balls for high strength SCC decreases the first crack load from 2.5% to 8.92% and decreases the ultimate load from 5.95% to 16.19%. Also increase the No. of balls, it notes reduced the slab stiffness.

Published: March 2022

" Studying photography and cinema allows a friendly and exemplifying entrance to art history, humanities, and various conceptions from social sciences. Photographs and films are excellent pretexts for understanding the society that makes them possible, transforms and turns them into cultural objects. While enjoying them, we also learn about the role they play in our daily lives and their potential to enrich our ways of being and thinking. Photography and cinema are objects of knowledge of study fields that have accounted for them based on different corpus notions, working methods and topics of interest. The theories of photography and film help to permanently re-invent our desires to know better what they are and how they produce logical thoughts and emotions."
Cystoscopic-guided scissor transection of intramural ectopic ureters as a novel alternate minimally invasive treatment option to laser ablation in female dogs: 8 cases (2011–2020)
Authors: Jacobson Else , Meler Erika N. , Delisser Peter J. , Thompson Ann L.
Published: March 2022

OBJECTIVE

To evaluate the safety and efficacy of cystoscopic-guided scissor transection of ectopic ureters (CST-EU) in female dogs.

ANIMALS

8 incontinent female dogs with intramural ectopic ureters.

PROCEDURES

For this retrospective case series, data were collected from medical records of dogs that underwent CST-EU to relocate the ectopic ureteral orifice to an anatomically normal trigonal location between June 2011 and December 2020. Outcome after hospital discharge was determined using owner telephone questionnaires.

RESULTS

Ectopic ureters were bilateral in 4 of the 8 dogs, and all dogs had other urogenital tract anomalies. Owner questionnaire follow-up was available for 7 dogs, and results indicated 6 dogs had improved urinary continence immediately following the procedure. At the last follow-up (44 to 3,384 days after CST-EU), 3 of the 7 dogs were completely continent with CST-EU alone, 3 others became continent or were markedly improved with the addition of medications for urethral sphincter mechanism incompetence, and 1 required ureteroneocystostomy, colposuspension, and an artificial urethral sphincter to become fully continent. Owners of 5 of the 7 dogs reported that they considered the outcome of CST-EU as good to excellent, and all owners reported that they would consider having CST-EU performed again should they have another incontinent dog. Complications were minor, and only 3 dogs showed transient lower urinary tract signs after CST-EU.

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated CST-EU could provide a safe, effective, minimally invasive alternative in the absence of laser technology for the treatment of intramural ectopic ureters in female dogs.

Authors: Havas Karyn A. , Yancey Caroline B. , Zhuang Jiexian , Braun Carissa , Smith David C.
Published: March 2022

OBJECTIVE

To evaluate the Brucella suis exposure status of pigs raised with outdoor access on farms in New York State and assess biosecurity and management practices of those farms.

ANIMALS

250 pigs that were raised for commercial purposes, had access to the outdoors, and were > 4 months of age on 24 farms in New York State.

PROCEDURES

Farms were randomly selected from a sampling frame generated for the study and contacted to recruit them to participate. Participating farms were provided a questionnaire to complete. Up to 30 pigs per farm were tested for serum anti-Brucella antibodies.

RESULTS

Farm were classified as seasonal and year round. Seasonal farms raised pigs for slaughter, and year-round farms bred pigs, raised them for slaughter, and sold live pigs to others to raise. None of the 250 pigs had antibodies to Brucella spp. Nevertheless, the biosecurity assessment revealed a need for enhanced practices in procurement and management of swine in a wide range of areas.

CLINICAL RELEVANCE

There was no evidence for ongoing B suis infection on these swine farms in New York State, but biosecurity and preventive practices at these facilities could be improved to prevent the introduction and spread of B suis and other pathogens.

Authors: Kumaresan Raja Sekar , Raj Marshal , Gopalakrishnan Lakshminarayanan
Published: March 2022

Bit manipulation plays a significant role in high-speed digital signal processing (DSP) and data computing systems, and shift and rotation operations are crucial functions in it. In general, barrel shifters are used to perform these operations effectively. Nano magnetic logic circuits are among the promising beyond-CMOS alternative technologies for the design of high-speed circuits. Most of the existing circuits that have been developed using nano magnets are combinational circuits. In this work, a barrel shifter is implemented and realised using in-plane nano magnetic logic. The proposed design is the first of its kind nano magnetic logic circuit. The nano magnetic logic circuit implementation, layout generation, simulation, and validation were performed using the ToPoliNano and ModelSim tools. The logical equivalent design was synthesised and evaluated using the Synopsys Design Compiler tool. The proposed barrel shifter was realised using majority logic has 1769037 nano magnets with a boxing area of 481 × 13104 µm2 and 3276 clock zones after optimisation with the Barycenter algorithm. The proposed barrel shifter realised using Boolean logic has 315276 nano magnets with a boxing area of 265 × 5028 µm2 and 1257 clock zones after optimisation with the Barycenter algorithm. The proposed design results demonstrate that complex systems can be developed using nano magnetic logic by combining combinational and sequential circuits.
Basketball self training shooting posture recognition and trajectory estimation using computer vision and Kalman filter
Authors: Egi Yunus
Published: March 2022

Self-shooting training is one of the fundamental criteria for success in basketball. Particularly, young players increase their performance with regular training. However, the training process becomes painful and time-consuming without a coach since the incorrect shooting posture causes missing shots, leading to reluctance. In this research, a self-shooting posture algorithm is developed to track the movement of basketball players and give them feedback about their position, angle, and basketball projectile trajectory information. The proposed algorithm uses computer vision techniques and Kalman filter to detect the best projectile trajectory using initial conditions such as acceleration due to gravity the initial velocity at the angle of launch having certain horizontal distance to the rim and the rim distance from the ground The acceleration of both gravity and air drag are altered by predefined parameters, including the drag coefficient basketball mass ball radius and silhouette area The proposed algorithm provides the shooting angle in real-time by placing the projectile angle on to the cropped image of the player posture and draws the projectile trajectory towards the basketball hoop According to the results, the players having a specified height can achieve the best shooting at the angle with air drag force. On the other hand, if there is no air resistance, the best shooting angle is deviated significantly. The other stats that are a total time of travel, maximum horizontal distance, maximum height and the time until the top are also given along with the results.

Published: March 2022

The streak tubes are widely used in National Ignition Facility (NIF), Inertial Confinement Fusion (ICF), and streak tube imaging lidar (STIL) as radiation or imaging detectors. The spatial resolution and effective photocathode area of the streak tube are strongly dependent on its operating and geometry parameters (electron optical structure and applied voltage). Studies about this dependence do not cover the full range of the parameters. In this paper, 3-D models are developed in Computer Simulation Technology Particle Studio (CST-PS) to comprehensively calculate the spatial resolution for various parameters. Monte Carlo Sampling method (M-C method) and spatial modulation transfer function method (SMTF) are employed in our simulation. Simulated results of the optimized spatial resolution are validated by the experimental data. Finally, the radii of the photocathode (R
c) and phosphor screen (R
s) are optimized. Geometry parameters of R
c=60 mm and R
s=80 mm are proposed to optimize the streak tube performances. Simulation and experimental results show that the spatial resolution and effective photocathode area of this streak tube are expected to reach 16 lp/mm and 30 mm-length while the voltage between cathode and grid (U
cg) is 150 V.

Authors: Andris Peter , Dermek Tomáš , Gogola Daniel , Přibil Jiří , Frollo Ivan
Published: March 2022

This article describes the analysis of the NMR (Nuclear Magnetic Resonance) stabilizer signal. Magnetic field of the standard is created using an electromagnet. Sufficiently high stability of the magnetic field is achieved with the help of a stabilizer with an NMR probe. The NMR phenomenon makes possible very accurate measurements of the static magnetic field, but the resulting stability depends also on supporting electronics. An analysis has been done and tolerances of the measured quantities have been estimated. The calculated tolerances indicate the needed features of the material. First the probe excites the FID (Free Induction Decay) signal in the water sample and acquires the signal answer. It is Fourier transformed and its spectrum is investigated. The actual magnetic field corresponds to the strongest frequency sample. It is utilized for the magnetic field strength correction and stabilization of it. The article brings many equations for such calculation.

Authors: Kim Yong-Sik , Dagalakis Nicholas G. , Marvel Jeremy , Cheok Geraldine
Published: March 2022

Most existing robot performance evaluation methods focus on single robotic arms performing independent motion tasks. In this paper, a motion gauge is proposed to evaluate the symmetrical coordinated-motion performance between two robotic arms. For this evaluation, the proposed device monitors the relative distance between the two robotic arms in real-time, which is used to evaluate the coordinated-motion errors with respect to accuracy, and repeatability between the two arms. The proposed metrology device is composed of two linear displacement sensors sliding on a linear rail, two ball-and-socket magnetic couplers for mounting to robotic arms, and a wireless communication module for data transmission. For validation, the proposed system monitored the two robotic arms programmed to simulate symmetrical coordinated motions.
The Need for a Global Aviation Cybersecurity Defense Policy
Authors: Nobles Calvin , Burrell Darrell , Waller Tyrone
Published: March 2022

Commercial aviation is vital to the economic health of the global economy. Commercial aviation as a global entity should be an international critical infrastructure that constantly safeguards and protects from malicious threats, including cybersecurity threat actors (Nobles, 2019). The international aviation industry needs a comprehensive cybersecurity defense plan to prevent cyber-based threats from negatively impacting civil aviation. Critical components of the global aviation systems consist of airport operations, air traffic management, ground operations, airline operations, unmanned systems, operations (Kessler, Craiger, & Haass, 2018), aviation maintenance, airport security (physical security), and cargo and logistics. The existing aviation infrastructure was designed, engineered, and implemented without forbearance on cybersecurity (Kessler, Craiger, & Haass, 2018). The lack of international cyber governance impedes the enforcement of cybersecurity policies; therefore, requiring a global-based alliance to create standards and best practices for evaluating and managing cybersecurity risks (Urban, 2017), especially in commercial aviation.

Published: March 2022

The number of vehicles in Bandung City continues to increase every year in line with the growth of motorized vehicle repair shops, thereby increasing the generation of hazardous waste from automotive shop activities. Based on Indonesia’s Governmental Decree 101 of 2014, vehicle maintenance and repair activities are one of the businesses that produce hazardous waste. This study focused on licensed and unlicensed automotive shops in Bandung City using stratified sampling methods by determining waste generation and composition, evaluating existing management systems, followed by developing management system alternatives. In determining the generation and composition of hazardous waste from automotive shop activities, a sampling of 42 unlicensed automotive shops and 11 unlicensed automotive shops in 3 areas of Bandung City was conducted. Sampling results of hazardous waste generation are 1.83 kg/vehicle/day for motorcycle automotive shops and 6.90 kg/vehicle/day for car automotive shops. The largest composition of hazardous waste produced in licensed shops is used oil with a proportion of 29.60 % and metal scrap component with a proportion of 35.83 % for unlicensed automotive shops. The projection results of hazardous waste generation in 2021 are around 774.26 tonnes/day. If the hazardous waste generated is not properly managed it can pose a risk to human health and the environment. An integrated management system for hazardous waste consists of packaging activity, storage activity, collection, transportation, and recycling activity.

Published: March 2022

The existence of indigenous peoples is one of the important things in supporting the sustainability of traditional values, especially those related to the design of residential buildings. The customary village of Muncan Village, Karangasem is one of the traditional villages in Bali where the existence of indigenous peoples still exists. This can be seen from the lives of these indigenous peoples in carrying out their daily lives still following the customs and rules contained in the region. Seeing the high existence of indigenous peoples in the village, it is necessary to examine the relationship of the existence of indigenous peoples to the development of architecture and interiors in these traditional Balinese houses. The purpose of this study was to determine the role of indigenous peoples in preserving traditional Balinese houses. This study uses a method with a qualitative approach and a cultural studies perspective. The results of this study indicate that the existence of indigenous peoples in the village of Muncan affects the architectural and interior development of their homes. This can be seen from the mindset of the community as well as various activities that contain elements of religion, tradition and belief that are applied to the architectural design of their residences. Broadly speaking, the architectural design of the residence still applies the concept of traditional Balinese architecture but has developed only in the form of materials and forms following developments according to the latest science and technology.

Published: March 2022

The editor’s letter aimed to expose the uncertainties and lack of evidence about the new coronavirus regarding breast-feeding from infected mothers and all possible risks in drug testing trials in the mothers and their infants. From comparisons among scientific studies, it was concluded that the vertical transmission is unlikely, and the benefits of breast-feeding outweigh risks of contamination. In addition, when evaluating the intrinsic properties of each drug, it is concluded that most drugs used in COVID-19 therapy are safe in the lactation period. The only exception was favipiravir since there is no solid information in the literature about its excretion in breast milk.

Published: March 2022

OBJECTIVES: Skin disorders are one of the main causes of medical consultation during childhood and its prevalence is highly influenced by environmental, genetic, and socioeconomic factors. In this study, we aimed to evaluate the epidemiological profile of pediatric patients attended at a dermatology referral service located in Amazon region, northern Brazil. METHODS: We retrospectively reviewed the medical history data of 638 pediatric patients (aged 0-15 years) presented at a dermatology referral service, between January 2014 and December 2019. The following variables were collected: gender, area of residence (urban or rural), diagnosis, date (year) of diagnosis, and comorbidities. Dermatoses were confirmed based on the available information of the patients’ detailed history, clinical presentation, and additional medical exams. RESULTS: A total of 831 diagnoses were included since 182 (28.52%) children had more than one dermatosis. The average age was 7.7 years, and the male-to-female ratio was 1: 0.94. The five most common categories of skin disorders were eczemas (29.72%), fungal infections (10.83%), tumors (9.51%), pigmentary disorders (8.90%), and urticaria/pruritus/drug eruptions (6.26%). Atopic dermatitis was the most reported disease, accounting for 18.41% of all diagnoses. The proportions of most dermatological conditions did not statistically differ between gender, except for pigmentary disorders that were significantly higher in female patients (p=0.01). CONCLUSIONS: Eczemas, fungal infections, and tumors were the most common groups of skin disorders among the evaluated children. However, more studies are needed to improve these data from northern Brazil.

OBJECTIVES: To report a case of an exclusive breastfeeding infant who developed pneumonia after bronchoaspiration of mineral oil for the treatment of intestinal pseudoconstipation. CASE REPORT: LGZ, male, 5 months old, previously healthy, exclusive breastfeeding, with maternal report of absence of evacuation for six days. She sought medical attention at the basic health unit (UBS), where mineral oil was prescribed and later, discharged home. She reported that when administering mineral oil the patient had a choking crisis followed by cough and vomiting. After four hours of the event he was brought to the emergency room due to grunting. He checked in presenting regular to poor general condition, tearful, tachypneic, with nasal obstruction and grunting, saturation oxygen 90% in ambient air. Non-invasive supportive measures were taken, followed by infectious screening and chest radiography. We chose immediate initiation of parenteral antibiotic therapy for exogenous lipoid pneumonia. He was admitted to the nursery for 10 days, received corticosteroid therapy (methylprednisolone 2mg/kg/day) and antibiotic therapy with amikacin (15mg/kg/day) and clindamycin (30mg/kg/dose) for secondary infection coverage. During hospitalization, the patient underwent chest computed tomography on the 3rd day and bronchoalveolar lavage was collected on the 9th day. He got better as expected and soon discharged after 10 days of hospitalization, in good general condition, eupneic, remaining in outpatient follow-up, without apparent sequelae. CONCLUSIONS: Lipoid pneumonia is a potentially fatal condition, caused by alveolar filling with oil. The main treatment is the immediate suspension of mineral oil.
Pediatric Rheumatology and Children's Palliative Care: conceptualizing the importance of this encounter
Authors: Ferreira Esther , Gramasco Hendrick , Iglesias Simone
Published: March 2022

Over the past few years, the pediatric’s patients profile has been changed, becoming more and more frequent the need for assistance of children living with chronic and life-threatening diseases. In this scenario, pediatric palliative care emerges as a way to provide integral care for these patients and their families. Pediatric rheumatology takes care of serious and life threatening diseases, therefore has an intersection with palliative care. The purpose of this article is to illustrate the intersection between these two fields in current medicine, performing a literature review. However, for our surprise, there are no article linking both themes available in the databases we searched for. Although there are no published articles, it is clear that there is a great concern of many professionals, in pediatric rheumatology, to assist the well-being of the children and their families. Thus, the concept of palliative care should be extended to pediatric rheumatology, in a systematized way, since the lack of knowledge about the theme makes it difficult to make a broad and adequate approach. The conclusion is, despite of the severity and great morbidity profile associated with childhood rheumatic diseases, the clinical indication of palliative care for these children should be made earlier, and specialized teams should be trained. This study points out the urgent need to introduce the concept of palliative care throughout the pediatric rheumatology’s teams.

OBJECTIVES: More than a third of children and adolescents who are followed by a palliative care unit (PCU) have a severe neurologic condition. The aim of this study is to review the indication of palliative care for patients with chronic debilitating neurologic conditions. METHODS: Databases literature review: PubMed, SciELO and LILACS, using the keywords combination for basic and advanced research. The following filters were applied: human beings, ages 0 through 18 years old, publication dated from the last 10 years, Portuguese, English or Spanish languages. RESULTS: After exclusion of papers that did not meet the study criteria, 24 articles were obtained on the matter. malnutrition is a major issue among patients with neurologic conditions, especially as a result of dysphagia. The use of enteral nutrition through feeding tubes is a valuable and underused measure to improve nutritional status. Excess orothraqueal secretions and dysphagia pose great risks to these patients, thus, procedures such as the laryngo-thraqueal separation can minimize those risks. Humor disorders must also be duly diagnosed and treated, as well as there should be a prompt discussion with caregivers about end of life care and grief. CONCLUSION: Palliative care indication should be encouraged more and more in pediatric neurology practice, as recommended, when faced upon the diagnosis of a potentially fatal condition or one that poses severe development impairment, aiming health quality improvements.

Fractions yielded  from Phellinus gilvus fruiting bodies by liquid-liquid partition of methanol extract contained various bioactive compounds such as phenolics, flavonoids and terpenes. Butanol, water and ethyl acetate fractions had high content of total phenolics, 158.12 – 247.31 mg of gallic acid equivalents (GAE)/g and low content of flavonoids, 21.74 - 36.05 mg of quercetin equivalents (QE)/g, respectively. These values highly correlated with their antioxidant activity including 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging potential with IC50 values of 84.5 -108.44 μg/mL and reducing power. These fractions showed moderate α-amylase inhibitory activity with IC50 values of 4.77, 10.69 and 3.9 mg/mL respectively. The P. gilvus fractions exhibited very slight inhibitory activity on the growth of Gram-positive and Gram-negative bacterial strains at the concentration of 20 mg/mL. The results suggest the utility of butanol, water, and ethyl acetate fractions from fruiting bodies of P. gilvus collected in Vietnam for further characterization in order to apply for diabetes or anti-aging prevention.

Preparation and characterization of magnetite Fe3O4-palm shell activated carbon composite has been carried out as an adsorbent of phenol compounds. Composites were preparation using the co-precipitationÂ  method by mixing Fe3O4 magnetite and suspension of activated carbon in water at 2:1 ratio by co-precipitation method. The functional groups, morphology and magnetization of the composites were characterized by FTIR, XRD, SEM-EDX and VSM. The XRD characterization result showed that the irregular activated carbon diffraction pattern on the composite showed that the carbon structure was amorphous and the peak was typical of Fe3O4 at an angle of 2Î¸ 35.3961Ëš with the distance of the diffraction plane or d = 2.53387Çº. VSM characterization shows the magnetic properties of magnetite are super paramagnetic with the resulting magnetization value of 15.93 emu/g, the remanence value (Mr) is 1.79 emu/g and the coercivity value (Hc) is 131.64 Oe. Adsorbent used for phenol adsorption with optimum at pH 6 with adsorption capacity wasÂ Â Â Â Â Â  6.71 mg/g, 120 minute contact time with adsorption capacity was 9.63 mg/g and the amount of phenol absorbed reached equilibrium a concentration of 300 mg/L of phenol with an adsorption capacity is 58.6 mg/g. The kinetics parameter showed that the adsorption followed pseudo second-order model.

The definition of runoff coefficient is the portion of rainfall that turn into direct runoff throughout an occurrence, and it is a significant perception in engineering hydrology and is extensively applied for design and as a diagnostic variable to show runoff creation in catchments. Event runoff coefficients may also be applied in event‐based developed flood frequency models that measure flood frequencies from rainfall frequencies and are valuable for recognizing the flood frequency controls in a specific hydrologic or climatic regime. Only a few previous studies worked on hydrological systems and processes deeply at catchment scale. Also in many catchments because of lacking data sets, analysis of land use change and water management and risks causes uncertainty in predictions of hydrological processes can be decreased. This problem is more important for predicting hydrology of ungauged basins in developing countries. The purpose of this study is to review predicting hydrology of ungauged basins.
Managing Tourism – A Missing Element?
Authors:   University of Strathclyde (Escocia), Butler Richard , Hart-Robertson Margaret ,   Universidad de Las Palmas de Gran Canaria (España)
Published: March 2022

The paper argues that despite the widespread use of the term management in the context of tourism destinations, there is little actual management of tourism or tourists in most destinations. The paper uses the Tourism Area Life Cycle (TALC) model (Butler 1980) as a lens through which to view some current issues and problems facing tourism destinations. It explores some of the basic elements of the TALC model including carrying capacity and triggers or forces bringing about change in destinations and argues that the reluctance of many stakeholders to adopt sustainable principles is reflected in current problems such as overtourism. Recognition of the often ignored political element in the sustainable triumvirate of economic, environmental and social components is important because without political support for appropriate initiatives has meant that efforts to move towards more sustainable destinations have often proved fruitless. The paper concludes that despite calls for new ways of defining success for tourism destinations and for drastically changing the nature and scale of tourism in the post‑pandemic future, it is likely that tourism will resume, at least for the short to medium term, in a form very similar to what existed before the advent of COVID 19.
Gestión turística ¿asignatura pendiente?
Authors:   University of Strathclyde (Escocia), Butler Richard , Hart -Robertson Margaret
Published: March 2022

Se habla mucho de la gestión turístico mas se ejerce poco. Se utiliza el modelo TALC (Butler 1980) como gran angular para explorar algunos de los temas problemáticos enfrentados por la mayoría de los destinos turísticos en la actualidad (pre‑COVID). Se centra en algunos aspectos básicos del modelo TALC como son la capacidad de carga y otras fuerzas endógenas o externas desencadenantes de cambios determinantes en los destinos turísticos. Se argumenta asimismo que exista cierta reticencia por parte de muchos stakeholders, sobre todo los elementos políticos a la hora de gestionar para la sostenibilidad, hecho que aboca a muchos destinos al sobreturismo y a la pérdida de calidad de vida. Hace falta visibilizar el papel político como cuarta pata de la sostenibilidad, ya que sin voluntad política, todo esfuerzo hacia la sostenibilidad termine fracasando. Hace falta asimismo redefinir la escala y la calidad del turismo ofrecido además de medir el éxito de un destino según parámetros muy distintos a los cuantitativos (números de turistas y cantidad bruta del gasto turístico) que se han utilizado en la época pre‑pandémica: es decir, gestionar hacia la sostenibilidad y la seguridad, claves del éxito en el futuro post‑COVID.
Contributos do network na gestão do património cultural para a inovação no território
Authors:   Universidad de Aveiro (Portugal), Leão Teresa Moreira Gomes
Published: March 2022

The present study aims at analyzing cooperative practices in built cultural heritage and identify how they affect innovation. To this end, a systematic revision of the literature and analysis of two interna‑ tional case studies (Italy and Spain) were carried out, concluding that: i) the impact of built cultural heritage on the draw of tourism is clear, above all in urban destinations; ii) the agents responsible for the manage‑ ment of built cultural heritage must be able to envision new targets and adapt their offer to a more demand‑ ing and independent tourist who wants to have access to sophisticated experiences with which to interact in a personalized way; iii) cooperation networks in tourism are management models that generate innovation in the offer with favorable impacts for the respective territories.
El Obelisco de Buenos Aires y su conformación como lugar turístico
Authors:   Universidad de Buenos Aires (Argentina), Rodríguez Moz Cush
Published: March 2022

One of the best‑known places in Buenos Aires is the Obelisk. It is, for that reason, frequently called a “symbol”, “icon” or “monument” of the city, and is one of its main tourist attractions. This paper analyses the Obelisk’s symbolism as a tourist site/sight in three dimensions: as a location that is accessible, centrally located and connected by multiple modes of transportation; as an attractive locale, the epicenter of both local actions (political acts and protests, celebrations of sports victories, commemorations of historical events) as well as global campaigns and initiatives carried out in the country; and as a monument with a meaning that has been historically constructed and is understandable to tourists. This last dimension is explored in detail by applying the theory of social semiosis and carrying out a historical analysis of the discourse associated with obelisks from the times of Ancient Egypt up to 19th‑century Europe and modern Latin America.

Heritage is important always in tourism and its presentation offers various areas of analysis such as time differences, social agents involved and the geographic scale. In this research, we present the perspec‑ tives of the scientists and managers. In order to establish a parallel between both perspectives, the analysis is located in Guaymallen and Maipu, Province of Mendoza, Argentina., both of which form part of the Northern oasis and have major parts of their territory within the Metropolitan Area of Mendoza. The data provided by the institution responsible for heritage in Mendoza, are confronted with the theory and new trends in the aca‑ demic field of heritage management. The concept of cultural heritage landscape is briefly developed in order to provide a possible theoretical framework in which to permit further research on the subject.
