Estrategias de andamiaje cognitivo en un ambiente de aprendizaje colaborativo en línea y la solución de problemas en una tarea auténtica: Prueba de un modelo
Authors: Ojeda Ayala Rosa 
Published: November 2022

Los procesos de solución de problemas, especialmente los problemas que presentan poca o ninguna estructura (mal estructurados), es una de las áreas más desatendidas por las investigaciones relacionadas al diseño de la instrucción (Jonassen, 2004). Estas destrezas son de particular interés en el desarrollo del aprendizaje adulto y la enseñanza en el nivel graduado. Algunos teóricos han propuesto el uso de estrategias (andamios cognitivos) basados en tecnologías que sirvan para apoyar estos procesos.
El presente estudio pretendió poner a prueba las estrategias sugeridas por Lin, Hmelo, Kinzer y Secules (1999), usando cuatro tipos de andamiaje (procesos, apuntes, modelaje y foro social) para facilitar los procesos de solución de problemas mal estructurados. El estudio se desarrolló como un estudio de caso múltiple, siguiendo el enfoque formativo (Reigeluth y Frick, 1999), enmarcado en el paradigma cualitativo, pero adoptando una metodología mixta. Su intención era auscultar la efectividad de los andamios en apoyar los procesos de solución de problemas auténticos del carácter mal estructurados mientras se desarrollaba el proyecto del curso en la modalidad en línea en la plataforma MOODLE. Se hizo énfasis en la herramienta del Wiki.
Los resultados sostienen que los andamios fueron efectivos en lograr su propósito. Aquellos que se caracterizaron por apoyar al estudiante en adquirir un dominio profundo, no solamente del contenido, sino de los procesos asociados a él y aquellos que le permiten monitorear su propio proceso de solución de problemas mientras aprenden fueron los más efectivos. Además, los estudiantes estimaron otros aspectos afectivos como importantes para este logro. La herramienta Wiki no produjo los resultados esperados.

Published: November 2022

Главной задачей государственной политики в области здравоохранения является обеспечение всех групп населения доступной медицинской помощью надлежащего качества. Одно из важных условий решения этой задачи - достижение определенного баланса между государственным и муниципальным управлением. Это возможно при разумном перераспределении полномочий между федеральным центром и регионами, а внутри регионов - между региональным и муниципальным уровнями. Система регионального здравоохранения имеет специфические черты и особенности в различных территориях. При организации медицинской помощи населению в регионах необходимо учитывать уровень их социально -экономического развития, особенности демографической ситуации, характер расселения (плотность населения, отдаленность населенных пунктов друг от друга и пр.), медико -биологические параметры здоровья населения, потребность в различных видах медицинской помощи и др. В статье представлена организация медицинской помощи населению одного из крупнейших муниципальных образований Московской области - городского округа Балашиха.
The main task of the state policy in the field of health care is to provide all groups of the population with affordable medical care of proper quality. Among the necessary conditions for solving this problem achievement of a certain balance between state and municipal management is of importance. It can be achieved by reasonable redistribution of powers between the federal center and the regions, and within the regions - sharing the powers between the regional and municipal levels. The regional healthcare system has specific features and peculiarities depending on different territories. While organizing medical care for the population in the regions, it is necessary to take into account the level of their socio -economic development, the peculiarities of the demographic situation, specificity of settlement (population density, remoteness of settlements from each other, etc.), the medical and biological parameters of the population’s health, the population’s need for various types of medical care, etc. The article presents the data of the organization of medical care to the population of one of the largest municipalities of the Moscow region, the Balashikha city district.

Published: November 2022

It is expected that a key part of a future with increasing use of maritime autonomous systems, will require collaborative and integrated approaches to working. How such approaches can be developed and tested was the focus of the Integrated Mission Management System 2019 (IMMS2019) project. The immediate objective was to experimentally demonstrate the ability of a single mission management system to control a fleet of heterogeneous, multi-domain autonomous platforms whereby their collaborative mission could be planned, verified, and delivered. To challenge the various spatial-temporal-energetic-communication-environmental constraints when operating such a fleet, real-world demonstration trials were carried out in Plymouth sound deployed from the Thales Maritime Autonomy Centre at Turnchapel Wharf. The trials were focussed on providing essential information into how such collaborations can be best executed, alongside invaluable lessons as to how existing platforms need to enhance their interoperability and in particular, robustness of communications and mission plans.

Published: November 2022

Although an established practice in potentially reversible severe respiratory failure, extracorporeal membrane oxygenation (ECMO) support remains controversial. Over the last 50 years, only 4 large scale randomised controlled trials relating to ECMO have been conducted in patients with ARDS. A meta-analysis of only 2 studies has demonstrated survival benefit in those supported with ECMO compared to optimal conventional therapy. With the advent of the COVID pandemic, ECMO utilisation increased, the guidelines evolved, and an unprecedented number of patients were referred for and managed with ECMO support. Approximately 15,000 patients have been supported to date, predominantly using veno-venous ECMO, with an overall in-hospital 90-day mortality of 47%. Although published data reported an increase in ECMO mortality to nearly 60% as the pandemic progressed, this was likely multifactorial, as subsequent data has demonstrated more promising mortality results. This highlights the unique challenges pertaining to patient selection and implementation of this finite support amid an evolving pandemic with many unknowns. Judicious and ethical patient selection is essential to ensure use for the greatest benefit. In this chapter we will outline the unique pathophysiology and clinical features of COVID-ARDS, indications for ECMO referral and patient selection, and implementation during the COVID-19 pandemic.

Published: November 2022

Wind power production has increased by a hundredfold during the last 20 years and represents roughly 3% of the total global electricity production. In recent years, technological changes in wind turbine configurations have enabled higher capacity factors for wind turbines. The results from the studies showed that wind as a source of energy for Växjö could be explored in order to achieve the goal of energy sufficiency and as well as sustaining the greenest city status in Europe. The simulation showed that 100 MW electricity could be generated from the wind sources with respect to the available data via global wind metrological data, literature, RETScreen Expert software., LCOE and IRR analysis tools. In addition, the Internal rate of return (IRR) of 8.7% which is good enough considering the proposed energy tax, energy security and environmental benefit cost ratio as well as reduced global weighted-average levelized cost of electricity (LCOE) from wind power technology make it more attractive for investor-Växjö municipality.

Published: November 2022

Early detection and identification of the first signs of autism play an important role in the implementation of support projects and appropriate interventions. Our study aims, on the one hand, to study the variations of the age of detection of the first signs of autism by the parents and, on the other hand, to explore the nature of these signs. It also seeks to verify whether the age of detection of early signs depends on certain characteristics such as the socioeconomic level of the parents. To do this, an analysis of the data collected as part of a prospective study of a population of 120 children was carried out. The results obtained indicate that the average age of identification of the first signs is around 19 months; and that the most reported signs relate to the area of ​​verbal communication. However, no significant relationship was found between the age of the detection of the first sign and the economic level of the parents.
Titanium-Based Alloys with High-Performance: Design and Development
Authors: Krishna Ram 
Published: November 2022

In recent years, titanium alloys with better properties have become increasingly popular. Their composition must be precisely designed to meet these demands. Screening alloy properties such as corrosion resistance, specific strength, properties to service at high temperatures, and microstructural stability requires a fair amount of effort and money to accomplish. By taking titanium-based alloys as an example, this chapter reviews the use of high-performance alloy design and development approach for industrial applications, in order to simplify the selection of titanium alloy compositions. The different high-throughput alloy design methods have been used by researchers to calculate diffusion coefficients of multiple elements using a thermodynamic database of atomic mobility. A composition with comprehensively optimal properties is selected by applying a rigorous screening criterion and then evaluating it in an experimental setting in order to come up with an optimal composition. Comparing this strategy with the data-driven material design methods that have been developed in recent times, few methods are more accurate and efficient, mainly because the diffusion pairs, the atomic mobility databases, and the refined physical models work together to make this strategy the most accurate and efficient. This approach could help develop high-performance titanium alloys, to overcome challenges of developing titanium alloys.
ΙΗΣΩΝ ΥΠΟΤΡΟΠΟΣ (Apoll. Rhod., IV 1161 ss.)
Authors: Belloni Luigi 
Published: November 2022

The Drepane episode focuses on the marriage between Medea and Jason and, as known, it introduces several allusions to their dramatic future in Corinth. Jason ὑπότροπος recalls different topics versus Odysseus; his return to Jolcus is conceived from the poeta doctus as a component of ἀμηχανίη which involves the Argonautic romance. At the opposite of Arete and Alcinoous and of Penelope and Odysseus as well, Medea and Jason are unable to establish a peaceful, ideal οἶκος after the golden fleece conquest.
El episodio de Drepane se centra en el matrimonio entre Medea y Jasón y, como es sabido, presenta varias alusiones a su futuro dramático en Corinto. Jasón ὑπότροπος trae a la memoria distintos tópicos respecto a Odiseo; su regreso a Yolco es concebido de parte del poeta doctus como un componente de la ἀμηχανίη difusa en el poema de los Argonautas. Al contrario de Arete y Alcínoo, por un lado, y de Penélope y Odiseo, por el otro, Medea y Jasón son incapaces de establecer un οἶκος pacífico e ideal tras la conquista del vellocino de oro.

ImportanceLarge-scale motorcycle rallies attract thousands of attendees and are associated with increased trauma-related morbidity and mortality.ObjectiveTo examine the association of major US motorcycle rallies with the incidence of organ donation and transplants.Design, Setting, and ParticipantsThis population-based, retrospective cross-sectional study used data from the Scientific Registry of Transplant Recipients for deceased organ donors aged 16 years or older involved in a motor vehicle crash and recipients of organs from these donors from March 2005 to September 2021.ExposureDates of 7 large US motorcycle rallies and regions near these events.Main Outcomes and MeasuresThe main outcomes were incidence of motor vehicle crash–related organ donation and number of patients receiving a solid organ transplant from these donors. An event study design was used to estimate adjusted rates of organ donation during the dates of 7 major US motorcycle rallies compared with the 4 weeks before and after the rallies in rally-affected and rally-unaffected (control) regions. Donor and recipient characteristics and metrics of organ quality were compared between rally and nonrally dates.ResultsThe study included 10 798 organ donors (70.9% male; mean [SD] age, 32.5 [13.7] years) and 35 329 recipients of these organs (64.0% male; 49.3 [15.5] years). During the rally dates, there were 406 organ donors and 1400 transplant recipients. During the 4 weeks before and after the rallies, there were 2332 organ donors and 7714 transplant recipients. Donors and recipients during rally and nonrally dates were similar in demographic and clinical characteristics, measures of organ quality, measures of recipient disease severity, and recipient waiting time. During rallies, there were 21% more organ donors per day (incidence rate ratio [IRR], 1.21; 95% CI, 1.09-1.35; P = .001) and 26% more transplant recipients per day (IRR, 1.26; 95% CI, 1.12-1.42; P &amp;lt; .001) compared with the 4 weeks before and after the rallies in the regions where they were held.Conclusions and RelevanceIn this cross-sectional study, major motorcycle rallies in the US were associated with increased incidence of organ donation and transplants. While safety measures to minimize morbidity and mortality during motorcycle rallies should be prioritized, this study showed the downstream association of these events with organ donation and transplants.

ImportanceExcess abdominal fat is a major determinant in the development of insulin resistance and other metabolic disorders. Increased visceral adipose tissue (VAT) seems to precede the development of insulin resistance and is therefore a prime target of childhood lifestyle interventions aimed at preventing diabetes.ObjectivesTo examine the effect of added exercise to a family-based lifestyle intervention program designed to reduce VAT plus subcutaneous (ASAT), intermuscular (IMAAT), and pancreatic (PAT) adipose tissue in children with overweight or obesity and to explore the effect of changes in VAT on insulin resistance.Design, Setting, and ParticipantsThis 2-group, parallel-design clinical trial was conducted in Vitoria-Gasteiz, Spain. A total of 116 children with overweight or obesity participated and were assigned to a 22-week family-based lifestyle program (control group [n = 57]) or the same program plus an exercise intervention (exercise group [n = 59]). Data were collected between September 1, 2014, and June 30, 2017, and imaging processing for fat depot assessments and data analysis were performed between May 1, 2019, and February 12, 2021.InterventionsThe compared interventions consisted of a family-based lifestyle and psychoeducation program (two 90-minute sessions per month) and the same program plus supervised exercise (three 90-minute sessions per week).Main Outcomes and MeasuresThe primary outcome of this study was the change in VAT between baseline and 22 weeks as estimated by magnetic resonance imaging. The secondary outcomes were changes in ASAT, IMAAT, and PAT. The effect of changes in VAT area on insulin resistance was also recorded.ResultsThe 116 participants included in the analysis (62 girls [53.4%]) had a mean (SD) age of 10.6 (1.1) years, and 67 (57.8%) presented with obesity. Significantly greater reductions were recorded for the exercise group in terms of reduction in VAT (−18.1% vs −8.5% for the control group; P = .004), ASAT (−9.9% vs −3.0%; P = .001), and IMAAT (−6.0% vs −2.6%; P = .02) fat fractions compared with the control group. Changes in VAT explained 87.6% of the improvement seen in insulin resistance (β = −0.102 [95% CI, −0.230 to −0.002]).Conclusions and RelevanceThese findings suggest that the addition of exercise to a lifestyle intervention program substantially enhanced the positive effects on abdominal fat depots in children with overweight or obesity. In addition, the reduction in VAT seemed to largely mediate the improvement of insulin sensitivity. These results highlight the importance of including exercise as part of lifestyle therapies aimed at treating childhood obesity and preventing the development of type 2 diabetes.Trial RegistrationClinicalTrials.gov Identifier: NCT02258126

ImportanceThe association of tamoxifen use with the risk of uterine diseases, such as endometrial cancer, in premenopausal women with breast cancer remains controversial. However, many studies have reported an increased risk of uterine disease among postmenopausal tamoxifen users.ObjectiveTo investigate the association of tamoxifen use with the risk of endometrial cancer and other uterine diseases in premenopausal women with breast cancer.Design, Setting, and ParticipantsA nationwide, population-based, retrospective longitudinal cohort study with an 18-year study period was conducted using data obtained from the Korean National Health Insurance Service. Participants included premenopausal women aged 20 to 50 years with breast cancer diagnoses between January 2003 and December 2018. Data were analyzed from April to December 2021.ExposuresTamoxifen treatment.Main Outcomes and MeasuresThe incidence of uterine diseases, including endometrial cancer, hyperplasia, polyps, and other uterine cancers, was identified in the study cohort using insurance claim codes. The incidence of uterine diseases per 1000 person-years was compared between women receiving tamoxifen and those not treated with adjuvant hormone therapy. Multivariable Cox proportional hazard regression analysis was performed to determine the risk of each uterine disease.ResultsAmong 78 320 female participants with a mean (SD) age of 42.1 (6.1) years, 34 637 (44.2%) were categorized into the tamoxifen group and 43 683 (55.8%) were categorized into the control group. Among tamoxifen users, during the mean (SD) follow-up duration of 6.13 (4.15) years, the incidence of newly diagnosed endometrial polyps was 20.13 cases per 1000 person-years, that of endometrial hyperplasia was 13.49 cases per 1000 person-years, that of endometrial cancer was 2.01 cases per 1000 person-years, and that of other uterine cancers was 0.45 cases per 1000 person-years. The risk of endometrial cancer was higher in the tamoxifen group than in the control group (hazard ratio, 3.77; 95% CI, 3.04-4.66) after adjusting for age, body mass index, history of diabetes, hypertension, dyslipidemia, polycystic ovary syndrome, gonadotropin-releasing hormone agonist treatment, and trastuzumab treatment.Conclusions and RelevanceIn this longitudinal cohort study, premenopausal Korean women with breast cancer who received tamoxifen as adjuvant hormone therapy had a significantly increased risk of endometrial hyperplasia, polyps, carcinoma, and other uterine cancers compared with those who were not treated with adjuvant hormone therapy. These findings suggest that clinicians should consider the risk of uterine disease among tamoxifen users, including premenopausal women.
