Published: January 2023

A finales del año 2019 comenzó una crisis sanitaria debido a la pandemia del COVID-19, la cual produjo cambios significativos en el estilo de vida de miles de millones de personas alrededor del mundo. Las medidas de prevención del COVID-19 tuvieron repercusiones psicológicas negativas en la población mundial. Durante los meses iniciales de confinamiento las personas experimentaron mayor cantidad tiempo libre en el día a día. Esto ha fomentado en la población la búsqueda y práctica de actividades que ayuden a llenar sus rutinas y aplaquen las consecuencias negativas de la crisis. El propósito del presente estudio fue examinar la relación entre practicar hobbies durante el confinamiento por COVID-19 y el bienestar subjetivo de jóvenes universitarios de República Dominicana. Para esto, se encuestaron 138 estudiantes universitarios de centro privados de Santo domingo. Los participantes contestaron la Escala de Satisfacción con la Vida, la SPANE y un cuestionario sociodemográfico que indagaba sobre la práctica de hobbies. Se compararon los resultados de ambas escalas entre las personas que habían desarrollado hobbies nuevos vs. aquellos que no lo hicieron. Se encontró que los participantes que practicaban hobbies presentaban puntuaciones significativamente superiores a quienes no practicaban en el bienestar subjetivo, especialmente en la satisfacción con la vida. Los participantes practicantes de hobbies parecen manifestar un mayor grado de conformidad con su vida. Este hallazgo apoya el uso de hobbies como un posible amortiguador parcial de los efectos negativos de la pandemia en el bienestar subjetivo individual

Turismo urbano, desarrollo local y sostenibilidad en el municipio de Panamá
Authors: Mora Rosa
Published: January 2023

El turismo en la Ciudad de Panamá ha sufrido cambios radicales debido a los nuevos escenarios generados por la globalización que demandan revisar y replantear los modelos tradicionales de gestión que no han dado buenos resultados, ocasionando preocupación en la sociedad. El objetivo de esta investigación consiste en revisar el estado de la cuestión y analizarlo. Para alcanzar esta meta, se utilizó un enfoque mixto dirigido hacia el desarrollo de estrategias que permitieran conocer la percepción e interpretación que, de dicha realidad tenían los actores locales. Se realizaron entrevistas a las instituciones públicas y organizaciones civiles vinculadas, se aplicaron encuestas a los ciudadanos comunes y empresarios dando resultados poco motivadores puesto que ninguno se encontraba satisfecho, principalmente el ciudadano común que no percibe un esfuerzo por parte del municipio para mejorar el aspecto urbano mientras que, a través de la observación directa se palparón avances de revitalización urbana. Esto indica que, hay voluntad, pero se carece de una efectiva publicidad, para darlo a conocer y así promover la ciudad como destino turístico. Además, le hace falta adecuarse un poco más en cuanto a infraestructuras urbanas modernas, espacios verdes y servicios turísticos, aunado a renovar y desarrollar más un turismo en armonía con la naturaleza. Para revertir esta situación se hace necesario el diseño de una estrategia de gestión con escenarios a mediano y largo plazo que permita un desarrollo local sostenible en beneficio de todos los actores
Analysis of Survival Data with Multiple Events
Authors: Meira-Machado Luís , Moreira Carla , Soutinho Gustavo , Azevedo Marta
Published: January 2023

An important aim in biomedical studies is to study how an intermediate event and prognostic factors influence the course of disease of a patient. In most cases, the effect of the intermediate event is considered a timedependent covariate and studied using extensions of the Cox proportional hazards model. Additionally, many of these studies often involve several endpoints, making the traditional approaches much more complicated. In such cases, multi-state models provide a useful tool to describe the survival process. This article aims to illustrate how multi-state models can be used as an alternative to traditional approaches. It also aims to offer guidelines for the correct use of these approaches through the analysis of survival data of patients with breast cancer. Several analyses were performed, and methods to evaluate the effect of covariates on transition intensities and to test some usual assumptions are discussed. Tree-based survival models, like the Cox proportional hazards models, are popular methods for constructing a prediction model in the field of medical research. We also present the results obtained by applying some tree-based models to the breast cancer data while showing their interpretation and utility. An overview of available software and software developed by the authors is provided to aid researchers in choosing an appropriate software tool for their purposes.

Gap-directed chemical lift-off lithographic nanoarchitectonics for arbitrary sub-micrometer patterning
Authors: Wang Chang-Ming , Chan Hong-Sheng , Liao Chia-Li , Chang Che-Wei , Liao Wei-Ssu
Published: January 2023

We introduce a unique soft lithographic operation that exploits stamp roof collapse-induced gaps to selectively remove an alkanethiol self-assembled monolayer (SAM) on Au to generate surface patterns that are orders of magnitude smaller than structures on the original elastomer stamp. The smallest achieved feature dimension is 5 nm using a micrometer-scale structured stamp in a chemical lift-off lithography (CLL) process. Molecular patterns retained in the gaps between stamp features and their circumscribed or inscribed circles follow mathematical predictions, and their sizes can be tuned by altering the stamp structure dimensions, including height, pitch, and shape. These generated surface molecular patterns can function as biorecognition arrays or be transferred to the underneath Au layer for metallic structure creation. By combining CLL process with this gap phenomenon, soft material properties that are previously thought as demerits can be used to achieve sub-10 nm features in a straightforward sketch.

Authors:   Faculty of Environmental and Power Engineering,  Cracow University of Technology, Ormaniec Paulina , Mikosz Jerzy
Published: January 2023

Wastewater treatment plants are considered to be one of the largest sources of microplastics in the natural environment. The problem of microplastics has been widely studied in many environments. It remains a subject of the growing interest for researchers. By definition, microplastic is plastic that does not exceed 5 mm in size. There are three stages in the study of microplastics in wastewater: sampling, treatment, and the identification of microplastics. This paper aims to review the strategies for sampling microplastics in wastewater treatment plants and their laboratory treatment to isolate microplastics. The collection of samples from the wastewater treatment plant is based on two mechanisms, namely a continuous filtering and pumping system and instantaneous sampling (steel bucket, glass jar, telescopic sampling). The removal of organic and inorganic matter is carried out with the use of physical and chemical analyses. The subject of this article is the compilation of the generally available research methods on microplastics. Based on the literature analysis, conclusions were drawn regarding the recommended methods of microplastic detection.

Authors: Vaidya Ravi D , Dua Gautam G.
Published: January 2023

The Indian television industry has come a long way in entertaining its audiences, which has spanned boundaries in recent years. The genre of reality shows has struck a chord with the viewers in recent times. The opportunity for advertising on TV is reducing; contemporary platforms are attracting the advertising buck. Marketers have been compelled to find alternate ways to grab eyeballs, and one such recourse has been to use covert advertisement as a tool of promotion. The objective of this study was to measure the perception and preference for reality shows. The study also explores the level of covert advertising (product placement) in reality shows found acceptable by the young viewers (aged 18 – 25 years, from Surat). The study reveals that youth has a wide acceptance of reality shows. They have no objection to the amount of covert advertising inserted in reality shows.

Health Benefits of Functional Foods
Authors: Jurek Joanna Michalina
Published: January 2023

Functional foods, also so-called supefoods being rich sources of many bioactive with attributed health-promoting properties, play important roles in disease prevention and may support treatments applied in certain chronic conditions and metabolic disturbances. To date, epidemiological evidence obtained from observational studies and clinical trials demonstrated that the regular consumption of nutrient-rich foods, particularly those of plant origin can increase vitality, bring benefits for overall health and reduce the risk of chronic disease. These benefits are predominantly linked to improved metabolic health, reduced inflammation, and body weight management. Furthermore, there is also increasing evidence that some of those products, like fermented foods, berry and tea beverages may also support mental health if consumed as part of a daily diet. Finally, some of the dietary superfoods are also recognized by cosmetic industries, which more often incorporate bioactive from these foods into cosmetic formulations or recommend dietary supplementation to improve skin condition.

Tuberculosis (TB) remains one of the major global causes of death; Mycobacterium Tuberculosis causes it. Approximately 10% of patients with TB may develop extrapulmonary bone tuberculosis, with the spine being the most affected, representing 1 to 2% of all TB cases. Pott disease is a form of extrapulmonary TB, and recently it has shown a significant resurgence in developed nations possibly impacted by global migration. Pott disease is often misdiagnosed or sometimes diagnosed during its late stages, which can be associated with devastating consequences to the patient. Brazil is among the top 20 countries with a high burden of tuberculosis; however, the published evidence is still limited, particularly during the last two years of the COVID-19 pandemic. Under this context, we present a clinical case of a 43 years old female patient with Pott disease with a minimally invasive surgical approach to decompress a multi-loculated abscess in the thoracic spine.

Published: January 2023

Sale, located along the Atlantic Ocean, is the third-largest city in Morocco. The Bouregreg river separates Sale from Rabat (Morocco’s capital city). This City is characterized by a high demographic density. Their main air pollution sources are traffic, ocean, potteries, fishing, domestic heating, and artisanal activities. Ambient PM2.5 particles were collected in an urban area of Sale City (Morocco) from July 2018 to July 2019. The sampling was carried out using a Dichotomous sampler and the Total X-Ray Fluorescence technique (TXRF) was used to evaluate the elemental composition of the collected filters. In this paper, chemical characterization, and source apportionment of PM2.5 were investigated. The results showed that the PM2.5 mass concentrations vary, during the sampling period, from 3.08 µg/m3 to 49.48 µg/m3 with an average of 17.30 µg/m3. The highest values were observed in winter while the lowest in summer. The influence of atmospheric transport scenarios on the levels of PM was carried out using air mass back-trajectories, using the HYSPLIT™ model. This study allowed identifying four main clusters arriving at our receptor site in Sale City: Iberian Coast (24%), Near Atlantic Ocean (33%), Local (28%), and Oceanic (15%). For seasonal variations of metal concentrations, K, Ca, V, Mn, Fe, Ni, Cu, Zn, As, Sr, Ba, and Pb exhibited their highest concentrations during winter while Ti and Cr, their highest concentrations were observed during Autumn. The Enrichment Factor (EF) analysis showed that Ti, Sr, Mn, K, Ca, and Ba are mainly originated from airborne dust with EF < 10, V, Cu, Cr have both natural and anthropogenic sources with 10 < EF < 100, while Ni, Zn, and Pb were mainly from anthropogenic source with EF > 100. Five factors were selected in Positive Matrix Factorization (PMF) model’s analysis: crustal contribution, road dust, brake wear, heavy oil combustion, and exhaust vehicle emissions. Their contributions to PM2.5 were 5%, 53.6%, 20.1%, 14.3% and 7%, respectively. Road dust and vehicle exhaust sources showed the highest contribution in winter; while soil dust, brake wear, and oil combustion sources contributed the most in summer. The present study could be considered as the first source apportionment study on PM2.5 fractions carried out in Sale City, Morocco.

Published: January 2023

In digital healthcare systems, with digitalization, data can be easily accessed. Considering the sensitivity of confidential information, the need for security is accelerated during this time. One of the most important security aspects is authentication which should be utilized. The available authentication models that rely on Machine Learning (ML) have some shortcomings, such as difficulties in appending new users to the system or model training sensitivity to imbalanced data. To address these problems, we propose an application of the Siamese networks using ECG signals which are easily reachable in digital healthcare systems. Adding some preprocessing for feature extraction in such a model could lead us to prominent results. This model is performed on ECD-ID and PTB datasets and approaches 92% and 95% of accuracy, respectively. A combination of simplicity and high performance made it an exclusive choice for smart healthcare and telehealth.

Published: January 2023

Introduction of fractional derivatives to the mechanics of fluid flow is relatively new. Even though the exact geometrical representations of fractional derivatives on fluid mechanics have not been discovered, recent literatures have proven that it is a paradox that will be useful in the future. Meanwhile, Riga plates are actuators that is convenient for controlling the velocity of fluid flows. Widely used in the field of marine engineering, the properties of fluid flowing over Riga plates are worth investigating. Thus, the aim of this study is to investigate the analytical solutions of an unsteady incompressible Casson nanofluid flowing over a Riga plate with presence of Newtonian heating. Carboxymethyl Cellulose (CMC) water was used as a prime example of Casson fluid with Copper-Oxide (CuO) nanoparticles. Coupled with a non-Newtonian fluid, the Casson fluid, and the Caputo-Fabrizio fractional derivative, the analytical solutions obtained will be beneficial in the engineering world as a tool for validating experimental and numerical studies. Through this study, analytical solutions were obtained and the profiles of both velocity and temperature of fluid with variations in parameters were investigated. It is observed that variations in the fractional derivative parameter produces a spectrum of solutions that abides the initial and boundary conditions set. An amplification of the modified Hartmann number increases both the velocity and temperature profiles, while an amplification of the nanoparticle volume fraction decreases the velocity profile but increase the temperature profile.

Published: January 2023

Emotional intelligence (EI) comes almost automatically to humans when we respond instinctively. This basic level of intelligence tells us how to behave in certain scenarios. However, can this understanding be used with the help of technology in selecting efficient managers in the construction industry where the rate of increase in costs and delays in the construction project never ends and even increases? This conceptual paper proposes a study exploring the theory of artificial emotional intelligence in the construction industry to reduce the increase in cost and time overrun in the project using mixed-method research. The indicators of construction project management success were collected from the literature. The questionnaire was prepared for the second phase, and sample data will be collected from construction project managers nationwide through an online survey to form the new model. Finally, the data will be tested and analysed to see the relationship between construction project managers' EI and project success using artificial intelligence technology. Later, they will be validated with a group of certified project managers in an appropriate workshop. This study will conclude whether selecting an excellent project manager can be achieved with the help of artificial intelligence, characterised by emotional intelligence theory. The study will also verify if there is a significant correlation between the performance of construction project managers with elements in the EI theory by using artificial technology and the success of construction projects.

Published: January 2023

Aim: In this study, it was aimed to investigate the effects of auditory stimuli and exercise on structural measurements, functional characteristics and sex hormones of rats fed with genetically modified organisms (GMO).Materials and Methods: A total of 64 8-week-old Spraque Dawley rats, 32 male and 32 female, were used in the study. GMO feeding, auditory stimulus and exercise were applied to both male and female rats. Control groups were also formed at the same time as the experimental groups. GMO application; It was fed by mixing 20ml water+20ml corn syrup per day. Auditory application; Segah and Hüseyni maqams were played at 55 decibels loudness for 60 minutes a day. Exercise app; It was applied as challenging swimming in an 80 cm long and 40 cm wide pool.Results: It was determined that the body weights of all rats treated with GMO showed a significant increase (p<0.05). Significant increases in blood lactate levels were observed in exercise-treated rats (p<0.05). It was determined that musical auditory stimuli were effective on sex hormones and significant decreases occurred in estrogen levels of female rats fed GMOs (p<0.05). Conclusion: It was observed that the preference of feeding with GMO significantly affected the body composition of the subjects. It was determined that swimming and sound stimuli were effective on sex hormones. It was determined that there was an increase in testosterone levels in male rats fed with exercise and GMO. A significant decrease was determined in the estrogen levels of female rats, especially in those fed with GMOs. For this reason, it was seen that the changes in the sex hormones caused by the high fructose-containing GMO diet can cause very important health problems. It was determined that more research on the subject should be done in order to explain the system response mechanisms of the organism, the relationship between exercise and auditory stimuli and GMO nutrition.

All infants underwent automated (A)-ABR. Forty parents of 20 infants who were born healthy and received NHS-pass results were included in the study as group I. Forty parents of 20 infants who were born healthy and received NHS-refer results were included in the study as group II. Forty parents of 20 infants hospitalized in the neonatal intensive care unit (NICU) for at least five days and received NHS-refer results were included in the study as group III. Beck Anxiety Inventory was administered to all parents in the groups.Results: When the anxiety levels were evaluated according to the groups, the anxiety scores of the parents in group III were higher than those in group I and group II (p<0.05). However, no difference was found between the parents’ anxiety levels in group I and group II. When the anxiety scores were compared according to the genders, there was no difference in the anxiety scores of the fathers between the groups (p>0.05). However, mothers in Group III had higher anxiety scores than mothers in Group I (p<0.05). Conclusion: Mothers of infants hospitalized in the NICU who received the NHS-refer result had higher anxiety levels than mothers who were born healthy and received the NHS-pass result. In order to keep the anxiety level of mothers of babies hospitalized in NICU under control, training can be organized for these mothers.

Aim: Femoral neck fractures are common injuries in orthopedic practice and result in significant morbidity and mortality. They are fractures in the intra-capsule area of the proximal femur. They usually occur in the elderly patient group. However, younger age groups could also experience femoral neck fractures as a result of high-energy traumas. The aim of the present study was to compare with the literature the outcomes in adult patients for whom surgical fixation was performed after femoral neck fracture using cannulated screws in our clinic.Materials and Methods: The study included patients for whom surgical fixation was performed for femoral neck fractures using cannulated screws between August 2010 and August 2012. Fracture non-union, delayed union, avascular necrosis and arthrosis were evaluated in patients. Avascular necrosis evaluation was performed using Ficat and Arlet classification. Functional outcomes were evaluated using Harris hip score.Results: The average follow-up period of our patients was 32 months (range: 24-48 months). Follow-ups indicated that 16 patients recovered without problems, walked with a double wand starting from about the third month with respect to the bone union status and full union was achieved in an average of six months. Non-union was observed in four patients. Ficat and Arlet avascular necrosis classification showed that four patients had avascular necrosis. The average time for these patients to be admitted to surgery was seven days. Five of our patients developed superficial wound infections. Antibiotic treatment and wound care were applied to our patients. When the patients were evaluated based on Harris hip score numerical rating chart, it was found that excellent outcomes were obtained in five patients, very good results in eight patients, good results in four patients, moderate results in two patients and poor results in one patient.Conclusion: Femoral neck fractures are a common type of injury in orthopedic practice and they result in significant morbidity and mortality when treated inappropriately. In order to reduce the rate of bone non-union, avascular necrosis or other complications that could be observed in patients who underwent surgical fixation after femoral neck fractures, and appropriate and acceptable reduction of femoral neck fracture should be realized as soon as possible, and stable fixation should be achieved.

Orbital eccentricities directly trace the formation mechanisms and dynamical histories of substellar companions. Here, we study the effect of hyperpriors on the population-level eccentricity distributions inferred for the sample of directly imaged substellar companions (brown dwarfs and cold Jupiters) from hierarchical Bayesian modeling (HBM). We find that the choice of hyperprior can have a significant impact on the population-level eccentricity distribution inferred for imaged companions, an effect that becomes more important as the sample size and orbital coverage decrease to values that mirror the existing sample. We reanalyze the current observational sample of imaged giant planets in the 5–100 au range from Bowler et al. and find that the underlying eccentricity distribution implied by the imaged planet sample is broadly consistent with the eccentricity distribution for close-in exoplanets detected using radial velocities. Furthermore, our analysis supports the conclusion from that study that long-period giant planets and brown dwarf eccentricity distributions differ by showing that it is robust to the choice of hyperprior. We release our HBM and forward-modeling code in an open-source Python package, ePop!, and make it freely available to the community.

We present a detailed prompt emission and early optical afterglow analysis of the two very-high-energy (VHE) detected bursts GRB 201015A and GRB 201216C, and their comparison with a subset of similar bursts. Time-resolved spectral analysis of multistructured GRB 201216C using the Bayesian binning algorithm revealed that during the entire duration of the burst, the low-energy spectral index (α
pt) remained below the limit of the synchrotron line of death. However, statistically some of the bins supported the additional thermal component. Additionally, the evolution of spectral parameters showed that both the peak energy (E
p) and α
pt tracked the flux. These results were further strengthened using the values of the physical parameters obtained by synchrotron modeling of the data. Our earliest optical observations of both bursts using the F/Photometric Robotic Atmospheric Monitor Observatorio del Roque de los Muchachos and Burst Observer and Optical Transient Exploring System robotic telescopes displayed a smooth bump in their early optical light curves, consistent with the onset of the afterglow due to synchrotron emission from an external forward shock. Using the observed optical peak, we constrained the initial bulk Lorentz factors of GRB 201015A and GRB 201216C to Γ0 = 204 and Γ0 = 310, respectively. The present early optical observations are the earliest known observations constraining outflow parameters and our analysis indicate that VHE detected bursts could have a diverse range of observed luminosity within the detectable redshift range of present VHE facilities.

To study the transportation of magnetic flux from large to small scales in protostellar sources, we analyzed the Nobeyama 45 m N2H+ (1–0), JCMT 850 μm polarization, and Atacama Large Millimeter/submillimeter Array (ALMA) C18O (2–1) and 1.3 and 0.8 mm (polarized) continuum data of the Class 0 protostar HH 211. The magnetic field strength in the dense core on a 0.1 pc scale was estimated with the single-dish line and polarization data using the Davis–Chandrasekhar–Fermi method, and that in the protostellar envelope on a 600 au scale was estimated from the force balance between the gravity and magnetic field tension by analyzing the gas kinematics and magnetic field structures with the ALMA data. Our analysis suggests that from 0.1 pc–600 au scales, the magnetic field strength increases from 40–107 μG to 0.3–1.2 mG with a scaling relation between the magnetic field strength and density of B ∝ ρ
0.36±0.08, and the mass-to-flux ratio increases from 1.2–3.7 to 9.1–32.3. The increase in the mass-to-flux ratio could suggest that the magnetic field is partially decoupled from the neutral matter between 0.1 pc and 600 au scales, and hint at efficient ambipolar diffusion in the infalling protostellar envelope in HH 211, which is the dominant nonideal magnetohydrodynamic effect considering the density on these scales. Thus, our results could support the scenario of efficient ambipolar diffusion enabling the formation of the 20 au Keplerian disk in HH 211.

We developed a novel global coronal COCONUT (Coolfluid Corona Unstructured) model based on the COOLFluiD code. The steady-state model is predetermined by magnetograms set as boundary conditions, while inside the numerical domain the corona is described by MHD equations. This set of equations is solved with the use of an implicit solver on unstructured grids. Here we present numerically obtained results for two extremes of the solar activity cycle represented by CR 2161 and CR 2219 for solar maximum and minimum, respectively. We discuss the impact of reconstruction level on representative solar corona solutions and thus also the impact of small magnetic structures on the overall structure of the solar wind. Moreover, both cases correspond to particular solar eclipses, namely those in 2015 March and 2019 July, to allow us the direct comparison of simulations with observed coronal features. We use a validation scheme proposed by Wagner et al. (from less to more sophisticated methods, i.e., visual classification, feature matching, streamer direction and width, brute force matching, topology classification). The detailed comparison with observations reveals that our model recreates relevant features such as the position, direction, and shape of the streamers (by comparison with white-light images) and the coronal holes (by comparison with extreme ultraviolet images) for both cases of minimum and maximum solar activity. We conclude that an unprecedented combination of accuracy, computational speed and robustness even in the case of maximum activity is accomplished at this stage, with possible further improvements in a foreseeable perspective.

The Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory will discover tens of thousands of extragalactic transients each night. The high volume of alerts demands immediate classification of transient types in order to prioritize observational follow-ups before events fade away. We use host galaxy features to classify transients, thereby providing classification upon discovery. In contrast to past work that focused on distinguishing Type Ia and core-collapse supernovae (SNe) using host galaxy features that are not always accessible (e.g., morphology), we determine the relative likelihood across 12 transient classes based on only 19 host apparent magnitudes and colors from 10 optical and IR photometric bands. We develop both binary and multiclass classifiers, using kernel density estimation to estimate the underlying distribution of host galaxy properties for each transient class. Even in this pilot study, and ignoring relative differences in transient class frequencies, we distinguish eight transient classes at purities significantly above the 8.3% baseline (based on a classifier that assigns labels uniformly and at random): tidal disruption events (TDEs; 48% ± 27%, where ± indicates the 95% confidence limit), SNe Ia-91bg (32% ± 18%), SNe Ia-91T (23% ± 11%), SNe Ib (23% ± 13%), SNe II (17% ± 2%), SNe IIn (17% ± 6%), SNe II P (16% ± 4%), and SNe Ia (10% ± 1%). We demonstrate that our model is applicable to LSST and estimate that our approach can accurately classify 59% of LSST alerts expected each year for SNe Ia, Ia-91bg, II, Ibc, SLSN-I, and TDEs. Our code and data set are publicly available.
