Social Robots in Hospitals: A Systematic Review
Hospital environments are facing new challenges this century. One of the most important
is the quality of services to patients. Social robots are gaining prominence due to the advantages
they offer; in particular, several of their main uses have proven beneficial during the pandemic. This
study aims to shed light on the current status of the design of social robots and their interaction with
patients. To this end, a systematic review was conducted using WoS and MEDLINE, and the results
were exhaustive analyzed. The authors found that most of the initiatives and projects serve the
elderly and children, and specifically, that they helped these groups fight diseases such as dementia,
autism spectrum disorder (ASD), cancer, and diabetes.This work has been supported by the PERGAMEX ACTIVE project, Ref. RTI2018-096986- B-C32, funded by the Spanish Ministry of Science and Innovation
Diversidad genética de Pinus pinaster en la Península Ibérica: correlación entre isoenzimas y caracteres cuantitativos
The estimation of genetic diversity using molecular markers is a major component of genetic conservation programs. However, molecular data are only weakly correlated with adaptive variation, which seriously limits the value of molecular information for guiding conservation policies. In this paper, we used allozyme markers to analyse the distribution of gene diversity in the native range of Pinus pinaster Ait. in the Iberian Peninsula, including seven marginal populations close to the Mediterranean Basin. Then, the variability of three quantitative traits (total height, stem form and survival) was computed using data from a multisite provenance test in central Spain and the two data sets were compared. Within the general pattern of variation, marginal populations presented levels of diversity closely related to those of nearby central populations, clearly suggesting that historical factors were more important than actual population sizes in determining levels of observed diversity. A weak but nevertheless significant correlation between allozymes and quantitative variability was found in maritime pine. Environmental gradients, as measured by geographic variables, are suggested to have selective effects on quantitative traits and to influence effective population size, which might explain the weak correlation found between allozyme and adaptive variability.Uno de los principales componentes de los programas de conservación genética es el uso de marcadores moleculares para la estimación de la diversidad genética. A pesar de ello, la variación observada en marcadores moleculares está débilmente correlacionada con la variación adaptativa, lo que limita seriamente la aplicación de estos estudios en el desarrollo de políticas de conservación. En este trabajo, se compara la distribución de la diversidad genética de Pinus pinaster Ait. en la Península Ibérica obtenida con marcadores moleculares (isoenzimas) y caracteres cuantitativos (altura, forma del fuste y supervivencia). El estudio incluye siete poblaciones marginales. Éstas, muestran valores de diversidad similares a los de poblaciones centrales próximas lo que sugiere una gran importancia de los procesos históricos regionales frente a efectos relacionados con el tamaño efectivo poblacional. La correlación de los marcadores moleculares utilizados con los caracteres cuantitativos medidos en los ensayos de campo es débil, aunque significativa. Esta correlación podría explicarse considerando efectos selectivos en respuesta a gradientes ambientales que afectan a su vez el tamaño efectivo de las poblaciones
Air quality in London: evidence of persistence, seasonality and trends.
The poor air quality in the London metropolis has sparked our interest in studying the time series dynamics of air pollutants in the city. The dataset consists of roadside and background air quality for seven standard pollutants: nitric oxide (NO), nitrogen dioxide (NO2), oxides of nitrogen (NOx), ozone (O3), particulate matter (PM10 and PM2.5) and sulphur dioxide (SO2), using fractional integration to investigate issues such as persistence, seasonality and time trends in the data. Though we notice a large degree of heterogeneity across pollutants and a persistent behaviour based on a long memory pattern is observed practically in all cases. Seasonality and decreasing linear trends are also found in some cases. The findings in the paper may serve as a guide to air pollution management and European Union (EU) policymakers.pre-print455 K

Affective Communication for Socially Assistive Robots (SARs) for Children with Autism Spectrum Disorder: A Systematic Review
Research on affective communication for socially assistive robots has been conducted to
enable physical robots to perceive, express, and respond emotionally. However, the use of affective
computing in social robots has been limited, especially when social robots are designed for children,
and especially those with autism spectrum disorder (ASD). Social robots are based on cognitiveaffective models, which allow them to communicate with people following social behaviors and
rules. However, interactions between a child and a robot may change or be different compared to
those with an adult or when the child has an emotional deficit. In this study, we systematically
reviewed studies related to computational models of emotions for children with ASD. We used the
Scopus, WoS, Springer, and IEEE-Xplore databases to answer different research questions related to
the definition, interaction, and design of computational models supported by theoretical psychology
approaches from 1997 to 2021. Our review found 46 articles; not all the studies considered children
or those with ASD.This research was funded by VRIEA-PUCV, grant number 039.358/202
Neoplasias quísticas mucinosas del páncreas: Caso clínico y revisión de la literatura
Mucinous cystic neoplasms of the pancreas occur relatively frequently and mainly affect women in the transition to menopause. Most of these neoplasms are unique but are located in the body and tail of the pancreas and have no communication with the pancreatic ductal system. Less than 20% are malignant. Evaluation should include clinical presentation, imaging, endoscopic ultrasonography, puncture biopsies, cytology and chemical analysis of the liquid to measure angiotensin converting enzyme (ACE) levels. Complete surgical resection is the only treatment that can improve long-term survival in patients with malignant mucinous cystic lesions. This article includes a review of the literature related to presentation of a case diagnosed by the surgical clinical gastroenterology group at Clínica la Presentación in Manizales, Colombia. © 2018 Asociaciones Colombianas de Gastroenterología, Endoscopia digestiva, Coloproctología y Hepatología
Influence of Winemaking Procedure and Grape Variety on the Colour and Composition of Young Red Wines
The influence of winemaking procedure and grape variety on the colour and composition of young redwines was evaluated. For this purpose, Tannat, Syrah and Merlot wines were elaborated in Uruguay in2011. Traditional maceration (TM), the addition of pectolytic enzymes (ENZ) and cold pre-fermentativemaceration before traditional maceration (CPM) were the alternative procedures of winemaking tested.Two batches of grapes (70 kg each) were employed for each winemaking procedure. Tannat wines hadthe highest colour intensity, red colour (a*), and anthocyanin, proanthocyanidin and alcohol content,and the lowest luminosity (L*) and pH values. CPM increased the colour intensity and total polyphenol,anthocyanin and proanthocyanidin content in Tannat and Merlot wines. Pectolytic additions enhancedcolour intensity and red colour and decreased the luminosity in all wines. Meanwhile, enzyme additionsenhanced proanthocyanidin content in all cases. Pectolytic enzyme significantly increased the methanollevels of the wines. Nevertheless, the amounts of this compound are far within maximum acceptable limits.Principal component analysis of the data shows significant separation between the wines of each variety,since the colour and composition are largely related to the cultivar and the vintage, despite the effect of thewinemaking procedures

A hybrid tgfu/se volleyball teaching unit for enhancing motivation in physical education: A mixed-method approach
Grounded in self-determination theory, this pre-experimental study analyzed the effects of a hybrid teaching games for understanding/sport education (TGfU/SE) volleyball teaching unit on students’ motivational outcomes, using a mixed-method approach. It also examined whether the intervention was equally effective for boys and girls. Participants were 53 secondary school students (Mage = 15.50, SDage = 0.57) who were taught through a hybrid TGfU/SE unit. The structure of this unit was designed according to the characteristics of SE model, while learning tasks were designed by using the pedagogical principles of TGfU model. Both self-reported validated questionnaires and focus groups were used before and after intervention to assess students’ motivational responses. After the hybrid TGfU/SE unit, both quantitative and qualitative findings showed improvements in students’ perceptions of need-support from the physical education (PE) teacher, basic psychological needs satisfaction, novelty, and variety satisfaction, as well as intrinsic motivation compared to baseline values. Although the hybrid TGfU/SE unit was effective in both genders, a large effect size was found for girls. Despite the existence of social and cultural stereotypes in team sports such as volleyball in favor of boys, results highlight the importance of developing hybrid TGfU/SE units to improve students’ motivational outcomes, especially in girls
