Educación física y convivencia escolar, una apuesta desde el currículo (Physical education and school coexistence, a proposal from the curriculum)
Authors: López Sánchez Milton Manuel , Arrieta-Rivero Shirly , Carmona-Alvarado Farid
Published: October 2022

Esta revisión sistemática tiene por objetivo determinar el alcance de las transformaciones o ajustes curriculares en las investigaciones donde la Educación Física (E.F.) es un elemento movilizador de la Convivencia Escolar (C.E.). Para tal efecto, se realizó una búsqueda sistemática en Scopus, Taylor and Francis, Redalyc y Dialnet, identificándose 17 estudios relevantes de acuerdo a los criterios de inclusión previamente establecidos. Para el análisis de la información la metodología empleada fue la Teoría fundamentada (Strauss & Corbin, 1998), considerándose ésta como un enfoque pertinente para la síntesis de estudios teniendo en cuenta que las publicaciones se tratan como datos. Entre los principales hallazgos está, la importancia dada a referentes curriculares como el modelo cooperativo y los juegos sociomotores para el trabajo de la C.E. en sus diferentes enfoques. Finalmente, el cambio en la actuación educativa implica una práctica pedagógica orientada hacia la consolidación del aspecto corporal, social y afectivo desde el tránsito de las interacciones socio-culturales que favorezcan las condiciones de vida en comunidad

Abstract: This systematic review aims to determine the scope of curricular transformations or adjustments in research where Physical Education (PE) is a mobilising element of School Coexistence (SC). To this end, a systematic search was carried out in Scopus, Taylor and Francis, Redalyc and Dialnet, identifying 17 relevant studies according to the previously established inclusion criteria. For the analysis of the information, the methodology used was Grounded Theory (Strauss & Corbin, 1998), which is considered a relevant approach for the synthesis of studies, considering that the publications are treated as data. Among the main findings is the importance given to curricular references such as the cooperative model and the socio-motor games for the work of SC in its different approaches. Finally, the change in the educational performance implies a pedagogical practice oriented towards the consolidation of the corporal, social and affective aspect from the transit of the socio-cultural interactions that favour the conditions of life in community.

Authors:   Rizal Medical Center, Department of Ophthalmology, Garcia Jard Evans , Abraham Lee James ,   Rizal Medical Center, Department of Ophthalmology
Published: October 2022

Herein, we present a case of 12-year-old male with ocular features of Marfan Syndrome. This case is of a twelve-year-old Filipino male seen in our institution with a five-year history of blurred vision. Ocular examination revealed poor visual acuity, high myopia, and ectopia lentis. Systemic examination revealed pectus carinatum, hypermobile joints, and arachnodactyly. There was high suspicion for Marfan Syndrome and the patient was subsequently referred to Pediatrics for further evaluation and management, where diagnosis was confirmed. This report stresses that a multidisciplinary approach is essential in the management of Marfan syndrome to improve vision and prevent complications, both ocular and systemic, brought about by the disease process.

Published: October 2022

Este estudo pretende realizar discussões iniciais sobre as possibilidades de utilização do conceito de escala nas pesquisas educacionais, analisando, em especial, as limitações e potencialidades das perspectivas microssocial e macrossocial na formação de professores. Os estudos atuais indicam que as pesquisas educacionais se utilizam de uma perspectiva em detrimento de outra. Acredita-se que apesar, dos diversos desafios ao tentar articular em um mesmo problema de pesquisa as perspectivas micro e macrossocial, a utilização das duas perspectivas em conjunto tende a ampliar a compreensão do problema estudado.

Cercetare-conservare. Traseul unei vetre decoratee descoperite în așezarea de epocă geto-dacică de la Cârlomănești.

Published: October 2022

At the end of the 19th century and the beginning of the 20th, the archeological sites unraveled a new category of monuments previously ignored – the ornamented hearths. Discovered for the fi rst time in England and Ukraine, then on the current territories of Bulgaria, Romania, France, Germany, Poland, the Czech Republic and Denmark, they belong, along with some other materials, to the European material and spiritual heritage. They were made from a material that was very much at hand clay. Their polished surface was sometimes decorated with lines made through incisions or by pressing a rope into it and it consisted in squares or concentric circles, meanders; they were separated into panes and had elliptical ornaments in the corners. The context of their discovery indicates that they were used either as mere household fi replaces or in rituals. Archeological literature provides us with an impressive amount of data regarding this subject. Things are completely different when it comes to seeing these architectural monuments in protected archeological sites or in museums. Two decorated hearths of this kind were found in the excavations from Cârlomănești - Cetăţuia in 2004; they are monuments of the Geto-Dacian classical civilization. They were situated in two houses that are believed to have been of public use. The plan of the buildings as well as their orientation, with the front facing North, points to a typical Geto-Dacian sanctuary. A secondary restoration and conservation project that was attached to the initial project of archeological research allowed for one of them (Cpl. 27) to be taken, conserved and eventually exhibited. The methods used in the operation of conservation and restoration are presented in detail hoping that the archaeologists will pay more attention to these kind of monuments in the future. Due to the joint research and conservation project, the Cpl. 27 has presently joined the other monuments of its kind and may be admired or studied in Buzău County Museum (Muzeul Judeţean Buzău).
Marmorne Architektur im kaiserzeitlichen Tomis. Zur Frage der Marmorwerkstatt
Authors:   Christian-Albrechts-Universität, Kiel, Institut für Klassische Altertumskunde. Klassische Archäologie, Toma Natalia
Published: October 2022

Die archäologische Auswertung des rekonstruierten Fundkomplexes der sog. Marmorwerkstatt wurde wegen des Fehlens einer Veröff entlichung der Ausgrabungen im südwestlichen Bereich der Stadt Tomis sowie der Freilegung der marmornen Bauteile zu unterschiedlichen Zeiten und deren Verteilung auf diverse Museen lange erschwert. Die Deutung als Werkstatt im Sinn eines räumlich defi nierten Ortes, an dem Marmor bearbeitet wurde, muss verworfen werden. Vielmehr sind die Bauteile im Kontext der Bebauung des südwestlichen Abhanges der tomitanischen Halbinsel zu sehen. Dieser barg off ensichtlich zahlreiche öff entliche Bauten, darunter auch den sog. Servilius-Fabianus-Bau. Dieser öff entliche Bau unbekannter Funktion war mit einer marmornen Fassade des Typus scaenae frons versehen. Da als Baumaterial dieser aus Bauteilen unterschiedlicher Bearbeitungsgrade bestehenden Fassade importierter Marmor fungierte, wird der Platz um den Bau herum zur Fertigstellung der Bauteile benutzt worden sein.

Auf einer übergeordneten Ebene deutet das Projekt zur Aufwertung und Verwertung der Ausgrabungsstätte Sarmizegetusa Regia touristische Entwicklungswege an, bei denen das bestehende Wechselspiel zwischen naturbelassenen Landschaft, archäologische Funde und vorhandene rurale (Infra-)Strukturen nicht als mühsam und unwirtschaftlich zu überwindende Hürde, sondern als Vorteil und Potenzial zu verstehen ist. Durch dieses Projekt wird beispielhaft gezeigt, was für eine Rolle die Architektur in der Inszenierung und Kommunikation vom Baukulturgut, in der Ansicht des Verfassers, spielen kann; weiters werden die Mechanismen verdeutlicht und ausgenutzt, durch denen die Mystik eines Ortes - in diesem Fall des Waldes - zum einen die wachsende Zielgruppe dieser Art von Less-is-More-Tourismus anspricht/anzieht und zum anderen die Aufnahme und die Verinnerlichung von kulturhistorischen Informationen unterstützt.
The architectural patronage of Miklós Bethlen in late seventeenth-century Transylvania
Authors:   independent researcher, arhitect, Cosnean Letiția
Published: October 2022

Analysing the architectural patronage of the noble Miklós Bethlen in Late Renaissance Transylvania, this article sheds light upon the scope of a noble building patronage in Early Modern Transylvania, reflecting at the same time the exceptional case of a patron playing the role of the architect. Miklós Bethlen is an exceptional fi gure of late seventeenth-century Transylvanian nobility, active both on the political scene and on the cultural one. He is better known due to the memoirs he has written during his last years spent in prison in Vienna, and published for the fi rst time in the middle of the nineteenth century. His architectural patronage became a landmark for the Transylvanian architectural history. The Bethlen castle in Sânmiclăuş (Alba county) represents an iconic building for his architectural patronage, built from the ground up following his plans and supervision. Nevertheless, his patronage extended to other less known buildings as well. Th is paper aims at identifying the building patronage of Miklós Bethlen on the basis of his memories, but also analysing the architectural context of late seventeenth-century noble residences from Transylvania. His architectural conceptions are re-evaluated as well following the novel observations of Professor Konrad Ottenheym who call attention to the direct relation between the residence from Sânmiclăuş and the architectural theory promoted by Nicolaus Goldmann in Leiden. Moreover, following the analysis of original drawings by Goldmann and the spatial disposition of the residence in Ţopa, the article suggests the hypothesis that Miklós Bethlen has contributed as well to the third building phase of the noble residence from Ţopa (ca. 1675).
Comprendre, c’est traduire. Rifl essioni sul complesso rapporto fra archeologia e conservazione
Authors:   Dipartimento di Architettura, Università di Chieti e Pescara, D’Avino Stefano
Published: October 2022

Il rapporto fra archeologia e conservazione è connesso con i concetti di ‘storia permanente’ e ‘materia signata’; il tema delle integrazioni in campo archeologico risente, del resto, degli sviluppi delle discipline storico-critiche, che mostrano oggi una crescente attenzione ed un apprezzamento verso tutti i livelli di stratifi cazione presenti sulle strutture antiche. Il progetto di restauro di un’architettura ridotta in frammenti si confi gura infatti come atto di interpretazione e traduzione. L’intervento sul testo lacunoso può pertanto giungere a soluzioni à l’identique, operazioni progettuali che perseguono una fi guratività architettonica simile all’originaria, ovvero confi gurarsi, negli esempi più convincenti, come un esercizio di reintegrazione in cui la permanenza della preesistenza è garantita dall’adozione di elementi formali francamente contemporanei e caratterizzati da una ricercata compatibilità e revesibilità; operazione in cui coesistono criticamente ‘dimensione estetica’ e rispetto del testo originario.

Authors: Souza Carolina Carvalho Garcia de , Alves Lucir Reinaldo
Published: October 2022

Esse artigo tem como escopo analisar a reestruturação produtiva e as especializações das mesorregiões brasileiras no período de 2000 e 2009. Foram utilizadas medidas de localização e especialização, a partir da variável emprego formal, e os resultados foram apresentados em mapas temáticos, para mostrar a distribuição espacial das atividades econômicas pelas mesorregiões do Brasil e com isso verificar se houveram mudanças espaciais ao longo do período analisado. Os resultados mostraram que as mesorregiões que mais reestruturaram suas estruturas produtivas, assim como aquelas que apresentaram maiores coeficientes de especialização, estavam localizadas na região Norte, Nordeste e Centro-Oeste. Uma das atividades que se consolidou como uma das principais especializações em todas essas mesorregiões no ano de 2009 foi a administração pública. Já o setor que mais apresentou mudanças, ou seja, o que mais se concentrou no período de 2000 a 2009 foi o setor da extração mineral. Além disso, pode-se perceber também que o dinamismo populacional do Norte e Centro-Oeste pode estar diretamente relacionado com a reestruturação produtiva dessas regiões.
Skin Lesions Classification and Prediction with Deep CNN

Published: October 2022

Given the success of Deep Convolutional Neural Network in Computer Vision tasks such as image classification, object detection, etc. ,DCNN has been applied to many other fields and lays the path for new research domains. Recently, by transfer learning, Esteva et al proposed in “Dermatologist – level classification of Skin Cancer with Deep Neural Networks” that “CNN achieves performance on par with all tested experts, demonstrating an artificial intelligence capable of classifying skin cancer with a level of competence comparable to dermatologists”. The results of experiments verify the intuition that features learned by pretrained models and the architectures of the DCNNs help learning features for a completely different domain dataset, here is the skin lesions dermatoscopic images dataset. Given the computational time and the test accuracy of fine-tuning the top layers and fine-tuning the whole model, for this particular dataset, I find that it’s better to fine-tune the whole pretrained model with fewer epochs and less computational time and achieve better accuracy.[1].

Social Attitudes toward ‘School English’ in Classroom Practice in South Korea from 1970 to the Present
Authors: Fouser Robert J.
Published: October 2022

This chapter investigates social attitudes toward ‘school English’ in South
Korea from 1970 to 1999. As the South Korean economy developed rapidly
in the 1970s, the perceived importance of English grew. The trend accelerated
in the 1980s and 1990s with continued growth and the transition
to democracy. The chapter uses a corpus of forty-nine selected articles
on English education from four major South Korean daily newspapers.
Articles were selected based on the insight provided into social attitudes
and analysed qualitatively to discern trends over time. Results showed
that pushes to reform ‘school English’ originated from policy markers
intent on linking English proficiency to economic and social development.
Instead of reflecting attitudes, policy makers acted as drivers of public
opinion.

"This paper aims to determine the possible impact of the seasonality of agricultural production on the prices of these products. Three main products were analysed, the majority of which are wheat, maize and sunflower production. With the help of national databases, product prices were analysed quantitatively and qualitatively, as well as statistically, over the last 5 years by calendar month. A series of researches have been carried out on the data, such as: analysing the dynamics of both annual and monthly prices, as well as determining the correlations between the price level for these products and the calendar month to which these prices refer. Following this analysis, the third-degree polynomial regression equations were determined, showing that product prices follow a sinuous trend, with high prices in the first part of the year, when supply is running out, then, during the harvesting period, there is a drop in price, given the sudden increase in supply on the market, and in the last months of the calendar year, the highest prices are recorded, given the additional cost of storing production following the harvesting campaign.

Responses of CIPS/AIM noctilucent clouds to the interplanetary magnetic field
Authors: Zhang Liang , Tinsley Brian , Zhou Limin
Published: October 2022

Abstract. This study investigates the link between the interplanetary magnetic field (IMF) By component and the noctilucent clouds (NLCs) measured by the Cloud Imaging and Particle Size (CIPS) experiment onboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. The mean ice particle radius in NLCs is found to be positively correlated with IMF By in the Southern Hemisphere (SH) and negatively correlated with IMF By in the Northern Hemisphere (NH), respectively, on a day-to-day timescale in most of the 20 summer seasons during the 2007–2017 period with a near 0 d lag time, and the response in the SH is stronger than that in the NH. Moreover, the albedo, ice water content and frequency of occurrence of NLCs present positive correlation with IMF By in the SH but no significant correlation in the NH. The superposed epoch analysis (SEA) further indicates the rm on average changes by about 0.73 nm after IMF By reversals, which is significant at the 90 % confidence level in Monte Carlo sensitivity tests. Our results suggest an IMF By-driven pathway: the influence of the solar wind on the polar ionospheric electric potential affects the nucleation processes in NLCs and consequently the ice particle radius and NLC brightness.
Quantifying the importance of vehicle ammonia emissions in an urban area of northeastern USA utilizing nitrogen isotopes
Authors: Walters Wendell W. , Karod Madeline , Willcocks Emma , Baek Bok H. , Blum Danielle E. , Hastings Meredith G.
Published: October 2022

Abstract. Atmospheric ammonia (NH3) is a critical component of our atmosphere that contributes to air quality degradation and reactive nitrogen deposition; however, our knowledge of NH3 in urban environments remains limited. Year-long ambient NH3 and related species
were measured for concentrations and the nitrogen isotopic compositions
(δ15N) of NH3 and particulate ammonium (pNH4+) were measured to understand the temporal sources and chemistry of NH3 in a northeastern US urban environment. We found that urban NH3 and pNH4+ concentrations were elevated compared to regional rural background monitoring stations, with seasonally significant variations. Local and transported sources of NHx (NH3+ pNH4+) were identified using polar bivariate and statistical back trajectory analysis, which suggested the importance of vehicles, volatilization, industry, and stationary fuel combustion emissions. Utilizing a uniquely positive δ15N(NH3) emission source signature from vehicles, a Bayesian stable isotope mixing model (SIMMR) indicates that vehicles contribute 46.8±3.5 % (mean ±1σ) to the annual background level of urban NHx, with a strong seasonal pattern with higher relative contribution during winter (56.4±7.6 %) compared to summer (34.1±5.5 %). The decrease in the relative importance of vehicle emissions during the summer was suggested to be driven by temperature-dependent NH3 emissions from volatilization sources, seasonal fuel-combustion emissions related to energy generation, and change in seasonal transport patterns based on wind direction, back trajectory, and NH3 emission inventory analysis. This work highlights that reducing vehicle NH3 emissions should be considered to improve wintertime air quality in this region.

Abstract. Dimethyl sulfide (DMS) is emitted by phytoplankton species in the oceans and constitutes the largest source of naturally emitted sulfur to the atmosphere. The climate impact of secondary particles, formed through the oxidation of DMS by hydroxyl radicals, is still elusive. This study investigates the hygroscopicity and cloud condensation nuclei activity of such particles and discusses the results in relation to their chemical composition. We show that mean hygroscopicity parameters, κ, during an experiment for particles of 80 nm in diameter range from 0.46 to 0.52 or higher, as measured at both sub- and supersaturated water vapour conditions. Ageing of the particles leads to an increase in κ from, for example, 0.50 to 0.58 over the course of 3 h (Exp. 7). Aerosol mass spectrometer measurements from this study indicate that this change most probably stems from a change in chemical composition leading to slightly higher fractions of ammonium sulfate compared to methanesulfonic acid (MSA) within the particles with ageing time. Lowering the temperature to 258 K increases κ slightly, particularly for small particles. These κ values are well comparable to previously reported model values for MSA or mixtures between MSA and ammonium sulfate. Particle nucleation and growth rates suggest a clear temperature dependence, with slower rates at cold temperatures. Quantum chemical calculations show that gas-phase MSA clusters are predominantly not hydrated, even at high humidity conditions, indicating that their gas-phase chemistry should be independent of relative humidity.
Ozone depletion events in the Arctic spring of 2019: a new modeling approach to bromine emissions

Abstract. Ozone depletion events (ODEs) are a common occurrence in the boundary layer during Arctic spring. Ozone is depleted by bromine species, which are most likely emitted from snow, sea ice, or aerosols in an autocatalytic reaction cycle.
Previous three-dimensional modeling studies of ODEs assumed an infinite bromine source at the ground.
In the present study, an alternative emission scheme is presented in which a finite amount of bromide in the snow is tracked over time. For this purpose, a modified version of the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) is used to study ODEs in the Arctic from February to May 2019. The model data are compared to in situ measurements, ozone sonde flights, and satellite data.
A simulation of the ODEs in the Arctic spring of 2009 using the infinite-bromide assumption on first-year (FY) ice is transferred to the spring of 2019, which
achieves good agreement with the observations; however, there is some disagreement in April 2009 and 2019 with respect to an overestimation concerning both the magnitude and the number of ODEs.
New simulations using the finite-bromide assumption greatly improve agreement with in situ observations at Utqiaġvik, Alaska, Zeppelin Mountain, Svalbard, and Pallas, Finland, in April 2019, suggesting that bromide on the sea ice is depleted to an extent that reduces the bromine release. The new simulations also slightly improve the agreement with observations at these sites in February and March. A comparison to measurements near Eureka, Canada, and Station Nord, Greenland, shows that multi-year ice and possibly snow-covered land may be significant bromine sources. However, assuming higher releasable bromide near Eureka does not remove all disagreement with the observations.
The numerical results are also compared to tropospheric-BrO vertical column densities generated with a
new retrieval method from TROPOspheric Monitoring Instrument (TROPOMI) observations.
BrO vertical column densities (VCDs) above 5×1013 molec. cm−2
observed by the satellite agree well with the model results. However, the model also predicts BrO VCDs of around 3×1013 molec. cm−2 throughout the Arctic and patches of BrO VCDs of around 1014 molec. cm−2 not observed by the satellite, especially near Hudson Bay. This suggests that snow at Hudson Bay may be a weaker bromine source in late spring compared to snow in the north.

Abstract. Clouds and precipitation play a critical role in the Earth's water cycle and energy budget. We present ground-level observations of snowfall coinciding with radiosonde launches in Sodankylä, Finland (67.367∘ N, 26.629∘ E) through a period of 8 cold months (October–April) in 2019 and 2020. They comprise 7401 depositing snow particles detected by a snowflake camera and 468 radiosonde profiles. Our results show that precipitating clouds were extending from ground to at least 2.7 km in altitude. Approximately one-quarter of them were mixed phase and the rest were likely fully glaciated. Estimations of the cloud top temperatures indicate that in roughly half of the snowfall events, ice might have been initiated through heterogeneous freezing. For such cases, the predicted ice-nucleating particle concentrations active at cloud top temperatures could explain the analysed ice crystal particle concentrations observed near ground in approximately one- to two-thirds of the cases. For the rest, ice multiplication was likely active. In a warmer climate, the relative proportion of solid to liquid cloud particles will probably decrease, with implications on the radiation balance.
Physiological flexibility of phytoplankton impacts modelled chlorophyll and primary production across the North Pacific Ocean

Abstract. Phytoplankton growth, and hence biomass, responds to variations in light and nutrient availability in the near-surface ocean. A wide variety of models have been developed to capture variable chlorophyll : carbon ratios due to photoacclimation, i.e. the dynamic physiological response of phytoplankton to varying light and nutrient availability. Although photoacclimation models have been developed and tested mostly against laboratory results, their application and testing against the observed flexible response of phytoplankton communities remains limited. Hence, the biogeochemical implications of photoacclimation in combination with ocean circulation have yet to be fully explored. We compare modelled chlorophyll and primary production from an inflexible phytoplankton functional type model (InFlexPFT), which assumes fixed carbon (C) : nitrogen (N) : chlorophyll (Chl) ratios, to that from a recently developed flexible phytoplankton functional type model (FlexPFT), which incorporates photoacclimation and variable C : N : Chl ratios. We couple each plankton model with a 3-D eddy-resolving ocean circulation model of the North Pacific and evaluate their respective performance versus observations (e.g. satellite imagery and vertical profiles of in situ observations) of Chl and primary production. These two models yield different horizontal and vertical distributions of Chl and primary production. The FlexPFT reproduces observed subsurface Chl maxima in the subtropical gyre, although it overestimates Chl concentrations. In the subtropical gyre (where light is sufficient), even at low nutrient concentrations, the FlexPFT yields higher chlorophyll concentrations and faster growth rates, which result in higher primary production in the subsurface, compared to the InFlexPFT. Compared to the FlexPFT, the InFlexPFT yields slower growth rates and lower Chl and primary production. In the subpolar gyre, the FlexPFT also predicts faster growth rates near the surface, where light and nutrient conditions are most favourable. Compared to the InFlexPFT, the key differences that allow the FlexPFT to better reproduce the observed patterns are its assumption of variable, rather than fixed, C : N : Chl ratios and interdependent, rather than strictly multiplicative, effects of light limitation (photoacclimation) and nutrient limitation (uptake). Our results suggest that incorporating these processes has the potential to improve chlorophyll and primary production patterns in the near-surface ocean in future biogeochemical models.
Upper-ocean flux of biogenic calcite produced by the Arctic planktonic foraminifera Neogloboquadrina pachyderma

Abstract. With ongoing warming and sea ice loss, the Arctic Ocean
and its marginal seas as a habitat for pelagic calcifiers are changing,
possibly resulting in modifications of the regional carbonate cycle and the
composition of the seafloor sediment. A substantial part of the pelagic
carbonate production in the Arctic is due to the calcification of the
dominant planktonic foraminifera species Neogloboquadrina pachyderma. To quantify carbonate production
and loss in the upper water layer by this important Arctic calcifier, we
compile and analyse data from vertical profiles in the upper water column of
shell number concentration, sizes and weights of this species across
the Arctic region during summer. Our data are inconclusive on whether the
species performs ontogenetic vertical migration throughout its life cycle or
whether individual specimens calcify at a fixed depth within the vertical
habitat. The base of the productive zone of the species is on average
located below 100 m and at maximum at 300 m and is regionally highly
variable. The calcite flux immediately below the productive zone (export
flux) is on average 8 mg CaCO3 m−2 d−1, and we observe that
this flux is attenuated until at least 300 m below the base of the
productive zone by a mean rate of 6.6 % per 100 m. Regionally, the summer
export flux of N. pachyderma calcite varies by more than 2 orders of magnitude, and the
estimated mean export flux below the twilight zone is sufficient to account
for about a quarter of the total pelagic carbonate flux in the region. These
results indicate that estimates of the Arctic pelagic carbonate budget will
have to account for large regional differences in the export flux of the
major pelagic calcifiers and confirm that substantial attenuation of the
export flux occurs in the twilight zone.
