Authors: Nesme N. , Foucher P-Y. , Doz S. , Lezeaux O. , Camy-Peyret C.
Published: June 2021

Abstract. The detection and the quantification of greenhouse gases is essential to climate change studies, avoid leakages in industrial site, prevent accidental explosions. Because of these properties, methane (CH4) is an important target gas in remote sensing quantification. We focused on industrial plume quantification with data obtained during airborne campaign with HySpex-Neo hyperspectral camera. The 1.4 m of spatial resolution allows comparing quantification methods on real data combined with full or semi-synthetic plume case. A linear method largely used in the literature is compared with a quantification method based on the rebuilt background image and the estimation of plume transmission (PTE method). We have developed a hybrid approach using intermediate results of two previous methods. The hybrid method is based on the optimal estimation (OE) formalism and is providing uncertainty estimates. We show that the linear method underestimates the concentration of plumes for concentration above 5000 ppm.m. For low reflectance pixels, the hybrid method is more robust than the PTE method. The uncertainty of the hybrid method is about 30% for pixels with concentrations above 5000 ppm.m. For a HySpex-Neo image, the total mass of the plume is underestimated by 30% with the linear method compared to the hybrid method.

Published: June 2021

Abstract. PM10 concentrations are essential for assessing air quality in arid areas. They are usually measured at air quality monitoring stations. The limited number of monitoring stations can make difficult to study significantly the spatial variability of PM10 over relatively large areas. This study aimed at evaluating the use of Aerosol Optical Depth derived from satellite data to estimate PM10 concentrations. The continuous coverage offered by remote sensing data helps to address the limitation encountered with the spatial distribution of relevant monitoring stations. In the current study we compared MODIS AOD at 550 nm included in MCD19A2 and we established a regression equation between AOD and PM10. The use of daily AOD at 1 km resolution helped establish regression with acceptable correlation coefficient. The regression equation is then used to create daily maps of estimated PM10 concentrations over the study area and helped assessing their variability.
ON-SITE DATA-PROCESSING ALGORITHM AND OPTIMIZATION FOR AIRBORNE ICE SOUNDING RADAR CONFIGURED ON THE “SNOW EAGLE 601”

Published: June 2021

Abstract. Airborne observation is an important approach to collect data in the remote, hostile Antarctica and study the relationship between the Antarctica and global climate. During airborne observations, it is necessary to conduct data processing and quality control on site, which can help to timely evaluate the status of airborne instruments, provide scientific clues, and develop ideal schemes for following airborne observations. As one critical component of airborne instruments, airborne ice sounding radar can delineate sub-ice bedrock topography and internal layers, which cannot be realized by other instruments. In this study, we present an on-site data processing algorithm for high-resolution and high signal-to-noise ratio (SNR) ice sounding radar data acquired by the “Snow Eagle 601”, the first fixed-wing airplane deployed by China for the Antarctic expeditions. In addition, the algorithm is further optimized in terms of static pre-allocated memory and parallel and block processing of data to enhance processing speed and meet the requirements for quality control and analysis of on-site data. Finally, we test the optimized algorithm with different volume of ice sounding radar data through implementing on different computer configurations, including i7, i5 CPU and 8G, 16G memory with the same disk. The results show that the average processing speed of the optimized algorithm is 5.143 times faster than the non-optimized algorithm on different computer configurations.

Published: June 2021

Abstract. In the context of climate change and rising frequency of extreme hydro-meteorological events around the world, flood risk management and mapping of heavy rainfall-related damages represent an ongoing critical challenge. For decades now, remote sensing has been largely used to investigate spatial and temporal changes in land use and water resources. Today, different satellite products provide fast and crucial knowledge for the study of hydrological disasters over large areas, possibly in remote regions, with high spatial resolution and high revisit frequency. Yet, until now, few works have sought to detect the full range of extreme rainfall-related damages with optical imagery, especially those caused by intense rainwater runoff beyond the direct vicinity of major waterways. The work presented in this paper focuses on the Aude severe weather event of October 15th, 2018, in the South of France, for which more than a thousand claims for agricultural disaster were registered, both related to river overflowing and rainwater runoff.The full resources of ground truths, contextual information, land use as well as digital elevation model (DEM) combined to high resolution and high frequency optical imagery (Sentinel-2, Pléiades) are used to develop an automatic damage detection method based on supervised classification algorithms. Through the combination of several indicators characterizing heterogeneous spectral variations among agricultural plots following the event, a Gaussian process classifier achieved various classification accuracies up to 90% on a large comparable and independent photo-interpreted validation sample. This work builds great expectations for applications in other areas with contrasted climate, topography and land cover.
THE USE OF SENTINEL 1/2 VEGETATION INDEXES WITH GEE TIME SERIES DATA IN DETECTING LAND COVER CHANGES IN THE SINOP NUCLEAR POWER PLANT CONSTRUCTION SITE
Authors: Çolak E. , Chandra M. , Sunar F.
Published: June 2021

Abstract. Recently, the demand for nuclear power plants has been increasing in developing countries in line with global energy demands. Turkey, one of the developing economies, is also making plans for nuclear power generation since 1970. The Sinop Nuclear Power Plant was a planned nuclear plant located in the Turkey's most northern point in an area where 99% of the land is forest, in Sinop Peninsula. If disputes are resolved and its construction continues, the plant is expected to be put into service in 2028. On the other hand, due to the construction of the nuclear power plant, the land cover in and around the plant site has changed, potentially causing major environmental changes. As an example, more than 650000 trees have been cut down so far for the construction of a nuclear power plant, which may have a negative impact on the region's ecological balances by endangering biodiversity and causing ecological damage. The aim of this study is to detect changes in forest areas from the start of nuclear power plant construction through December 2020 using Sentinel 1 SAR and Sentinel 2 optical time series images. For this purpose, different radar and optical vegetation indices such as Modified Radar Vegetation Index (mRVI), Modified Radar Forest Degradation Index (mRFDI), and Normalized Difference Vegetation Index (NDVI) were applied using Google Earth Engine (GEE) Sentinel 1/2 satellite time series for 2015–2020 period. As a result, the indices used were found to yield findings consistent with the reported negative land cover change. In addition, correlation analysis were made between the radar vegetation indices used and a very high negative correlation (−0.99) was found. The annual distributions of the values of the three indices used were statistically evaluated using boxplots.

Published: June 2021

Abstract. The objective of this project was to compare two non-parametric classification methods (“Support Vector Machine” – SVM and “Artificial Neural Networks” – ANN) of road regions in high spatial resolution images and associated with data from Airborne Laser Scanning. The study aims to verify what kind of influence the layers of attributes have on the performance from respective classifiers: SVM and RNA. Our method based on tests of this classifiers on 4 bands of airborne images and normalization of the digital surface model (DSM) for showing only information on objects height in relation to ground and not of these in relation to the ground and relief, generating band 5. The samples were used to train chosen non-parametric classifiers (training sets for each different input image/landscape). All classifications had the same set of training samples and the same classification parameters. The optimal parameters for classifications were obtained through the existing library in the Weka mining package: LibSVM and LibMultiLayerPerceptron. Our results demonstrated the existence of a direct relationship between the elevation band of the targets in relation to the terrain (band 05) with the improvement of their performance and lower degree of between bands correlation can also be considered a factor that has a positive influence. As for Neural Networks, the experiment results demonstrate that the presence of the near infrared band (band 04) was decisive for the performance improving of certain combinations in relation to others.
Contrasting regional variability of buried meltwater extent over 2 years across the Greenland Ice Sheet
Authors: Dunmire Devon , Banwell Alison F. , Wever Nander , Lenaerts Jan T. M. , Datta Rajashree Tri
Published: June 2021

Abstract. The Greenland Ice Sheet (GrIS) rapid mass loss is primarily driven by an increase in meltwater runoff, which highlights the importance of understanding the formation, evolution, and impact of meltwater features on the ice sheet. Buried lakes are meltwater features that contain liquid water and exist under layers of snow, firn, and/or ice. These lakes are invisible in optical imagery, challenging the analysis of their evolution and implication for larger GrIS dynamics and mass change. Here, we present a method that uses a convolutional neural network, a deep learning method, to automatically detect buried lakes across the GrIS. For the years 2018 and 2019 (which represent low- and high-melt years, respectively), we compare total areal extent of both buried and surface lakes across six regions, and we use a regional climate model to explain the spatial and temporal differences. We find that the total buried lake extent after the 2019 melt season is 56 % larger than after the 2018 melt season across the entire ice sheet. Northern Greenland has the largest increase in buried lake extent after the 2019 melt season, which we attribute to late-summer surface melt and high autumn temperatures. We also provide evidence that different processes are responsible for buried lake formation in different regions of the ice sheet. For example, in southwest Greenland, buried lakes often appear on the surface during the previous melt season, indicating that these meltwater features form when surface lakes partially freeze and become insulated as snowfall buries them. Conversely, in southeast Greenland, most buried lakes never appear on the surface, indicating that these features may form due to downward percolation of meltwater and/or subsurface penetration of shortwave radiation. We provide support for these processes via the use of a physics-based snow model. This study provides additional perspective on the potential role of meltwater on GrIS dynamics and mass loss.
Assessing volumetric change distributions and scaling relations of retrogressive thaw slumps across the Arctic
Authors: Bernhard Philipp , Zwieback Simon , Bergner Nora , Hajnsek Irena
Published: June 2021

Abstract. Arctic ice-rich permafrost is becoming increasingly vulnerable to terrain altering thermokarst, and among the most rapid and dramatic of these changes are retrogressive thaw slumps (RTS). They initiate when ice-rich soils are exposed and thaw, leading to the formation of a steep headwall which retreats during the summer months. These impacts, the distribution and scaling laws governing RTS changes within and between regions are unknown. Using TanDEM-X-derived digital elevation models, we estimated RTS volume and area changes over a 5-year period. We contrasted 9 regions (Eurasia: 4, North America: 5), with a total size of 220,000 km3, and over that time all 1853 RTSs combined mobilized a total volume of 17 · 106 m3 yr−1 corresponding to a volumetric change density of 77 m3 yr−1 km−2. Our remote sensing data revealed inter-regional differences in mobilized volumes, scaling laws and terrain controls. The area-to-volume scaling could be well described by a power law with an exponent of 1.15 across all regions, however the individual regions had scaling exponents ranging from 1.05 to 1.37 indicating that regional characteristics need to be taken into account when estimating RTS volumetric change from area change. The distributions of RTS area and volumetric change rates followed an inverse gamma function with a distinct peak and an exponential decrease for the largest RTSs. We found that distributions in the high Arctic were shifted towards larger values. Among the terrain controls on RTS distributions that we examined, slope, adjacency to waterbodies and aspect, the latter showed the greatest, but regionally variable association with thaw slump occurrence. Accounting for the observed regional differences in volumetric change distributions, scaling relations and terrain controls may enhance the modelling and monitoring of Arctic carbon, nutrient and sediment cycles.

Published: June 2021

Abstract. Ice shelf dynamics and morphology play an important role in the stability of floating bodies of ice, in turn impacting their ability to buttress upstream grounded ice. We use a combination of satellite-derived data, airborne and ground-based radar data, and oceanographic data collected at the Nansen Ice Shelf in East Antarctica to examine the spatial variations in ice shelf draft, the cause and effects of ice shelf strain rates, and the role of a suture zone driving channelization of ocean water and resulting sub-ice shelf melt and freeze-on. We also use the datasets to assess limitations that may arise from examining only a sub-set of the data, in particular the reliance on hydrostatic balance equations applied to surface digital elevation models to determine ice draft morphology. We find that the Nansen Ice Shelf has highly variable basal morphology driven primarily by the formation of basal crevasses near the onset of floating ice convergence in the suture zone. This complex morphology is reflected in the ice shelf strain rates but not in the calculated hydrostatic balance thickness, which underestimates the scale of vertical and horizontal variability at the ice shelf base. The combination of thinner ice in the channelized suture zone, enhanced melt rates near the ice shelf edge, and complex strain rates driven by ice dynamics and morphology have led to the formation of fractures within the suture zone that have resulted in large-scale calving events. Other Antarctic ice shelves may also have complex morphology, which is not reflected in the satellite data, yet may influence their stability.

Negotiating Open Access Journal Agreements: An Academic Library Case Study
Authors: Hosoi Mihoko
Published: June 2021

The COVID-19 pandemic has presented an opportunity for academic libraries to advance open access (OA) to scholarly articles. Awareness among faculty on the importance of OA has increased significantly during the pandemic, as colleges and universities struggle financially and seek sustainable access to high-quality scholarly journals. Consortia have played an important role in establishing negotiation principles on OA journal agreements. While the number of OA agreements is increasing, case studies involving individual libraries are still limited. This paper reviews existing literature on publisher negotiation principles related to OA journal negotiations and reflects on recent cases at an academic library in Pennsylvania, in order to identify best practices in OA journal negotiations. It provides recommendations on roles, relationships, and processes, as well as essential terms of OA journal agreements. This study’s findings are most relevant to large academic libraries that are interested in negotiating with scholarly journal publishers independently or through consortia.

Análisis crítico del concepto resiliencia en la política pública de Puerto Rico: una aportación del Trabajo Social
Authors: Álvarez-Rosario Génesis
Published: June 2021

Resiliencia es un concepto que ha tomado mayor resonancia en Puerto Rico tras el impacto de los huracanes Irma y María, integrándose indistintamente en la forma discursiva, teórica o práctica, en el trabajo con personas y en las gestiones gubernamentales. En este trabajo se presenta un análisis de contenido sobre las políticas públicas propuestas por la Asamblea Legislativa de Puerto Rico que incorporaron el concepto resiliencia. Se analizan las conceptualizaciones sobre resiliencia de la teoría crítica de Michel Foucault, con la finalidad de problematizarlas y contextualizarlas en las imbricaciones de las dinámicas sociales, políticas, económicas y ambientales de la Isla. Además, se abordan las implicaciones de este análisis para la gestión de política pública desde la perspectiva de Trabajo Social, así como recomendaciones para una práctica antiopresiva.
Relación entre violencia de género por la pareja y apoyo social en mujeres colombianas. Análisis con perspectiva de género
Authors: Reina-Barreto Johanna Alexandra
Published: June 2021

En este estudio se comparan: las características sociodemográficas, las socioeconómicas, los tipos, las intensidades y las secuelas de violencia en el grupo de mujeres adultas que busca apoyo social por haber sido objeto de la violencia de la (ex)pareja heterosexual en relación con el grupo de quienes no han buscado apoyo. Describe las fuentes de apoyo que conforman las redes formal e informal, su densidad, y la relación entre la búsqueda de apoyo y la violencia experimentada. La muestra la conforman 6.279 mujeres entre 25-49 años que respondieron a la Encuesta de salud Bogotá-2011. Se utilizan tablas de contingencia con contraste Chi-cuadrado y coeficiente V de Cramer, para comprobar la intensidad de la relación entre variables. Los resultados reportan altas prevalencias de violencia en todas las tipologías estudiadas: las mujeres que buscan apoyo informan hasta tres veces más violencia y secuelas que las mujeres del grupo que no lo busca. Quienes no buscan apoyo viven con el agresor en familias con características del modelo patriarcal y con posibles testigos familiares de esa violencia. Quienes lo buscan son personas separadas-divorciadas con más hijas(os), con la familia como su principal fuente de apoyo; si bien la estructura de la red cambia conforme se acumula más violencia en sus cuerpos. Los resultados globales sugieren un continuum de violencia, donde el control opera como un sistema de opresión legitimado culturalmente. Se propone la utilidad de estos resultados para aplicarlos al diseño de programas de intervención con mujeres.

Authors: Hassan Abrar Ul , Guleryuz Cihat
Published: June 2021

Both lithium ions and protons have been directly implicated in oxygen reduction and evolutionary responses and lithium hydroperoxide and lithium hydroxide are recognized as prevailing discharge ingredients. Attributes of lithium hydroperoxide shall be evaluated in principle. Impressively, the reaction of lithium hydroperoxide to triiodide shows quicker material properties, which allows a slightly lower excessive-potential during the charging cycle. The frontier molecular orbitals (FMOs), UV-Vis, and solvation model-based studies remained unknown. Therefore, we intended to study the Reaction path study, natural bond orbital, FMOs, UV-VIS, thermodynamic properties and medium influence on solvation energies, dipole moment, FT-IR and FT-Raman using polarizable continuum model (PCM) and density-based solvation model (SMD). The electronic properties of the molecule were calculated by M06-2X/6-31G (d,P) and B3LYP/6-31G (d,p) level of theories. Natural bond orbital discloses that the optimum stabilization energy managed to reach 39.64 kJ / mol, which is accountable for the extra stability of the compound. Based on materials impacts on FT-IR and FT-Raman intensities are identified in the understudy compound. Frequencies improved from gas to the solvent process.

Published: June 2021

Exploring the culture and literature of countries around the world is increasingly important in the current trend of international exchange and integration. Therefore, foreign literature disciplines, including Japanese literature, occupies an increasingly essential position in the curriculum of Dong Thap University. However, the perception and teaching of Japanese Haiku poems have long been challenged due to language barriers as well as cultural differences. In order for enhancing the quality of teaching Haiku poetry to Literature Pedagogy majors at Dong Thap University, the article presents a new approach towards classical Haiku poetry through the perspective of ink painting art (aka painting art). With the aim of observing the beauty of Japanese literature and culture, the study analyzes the causes and some specific manifestations of the similarities between Japanese ink painting art and classical Haiku poetry in terms of artistic methods. The root cause lies in the influence of Zen, as a cultural characteristic of the Japanese spirit, and the specific manifestations include the technique of empty spaces in ink painting art, and the empty poetic strategy in classical Haiku poetry, the features of the conception scenery and the moment characteristic in both Oriental art genres.

Authors: Nguyen Quang Nhat
Published: June 2021

Peer observation is among the popular tools to evaluate teacher's performance in the classroom. As education evolves and becomes more eclectic, the focus of peer observation is not merely to assess teachers but also to facilitate them in pursuing their professional development. Characterized by the SALSA (Search, Appraisal, Synthesis and Analysis) framework of Grant and Booth (2009), this critical review searches, appraises, synthesizes, and analyzes the literature in contemporary models of peer observation globally, based on which the author adopts two peer-observation models left out by other researchers. The article then critically discusses the questions regarding the benefits and concerns, as well as proposes holistic solutions to enhance peer observation of teaching. Finally, the author points out the research gaps and offers further pedagogical recommendations for applying peer observation of teaching as a professional development protocol from both managerial and professional perspectives.

THE IMPACT OF THE SPINAL DEFICIENCIES PROPHYLAXIS UPON THE 6-7 YEAROLD PRESCHOOL CHILDREN PHYSICAL DEVELOPMENT LEVEL
Authors:   Clinical Hospital CF no 2, Romania, Buciu Daniela
Published: June 2021

The problem of prophylaxis of various deficiencies of the skeletal bone of preschool children and first of all of the spine, as a basic pillar in their development, was and remains in the sights of specialists in the field of physical education and sports. It has been shown experimentally that the means of physical education can and must be a basic support in terms of spinal deficiencies prophylaxis, especially in children of preschool age, in this case the age of 6-7 years. It is at this age that the first symptoms occur related to the appearance of one or another spine deficiency. If no direct action is taken, with the application of specific means to eliminate or reduce the occurrence of these deficiencies, the situation may become much more serious and much more difficult to resolve. In this case, a series of means of physical education are proposed in the form of complex exercises and dynamic games, which have been used successfully in the training process of preschoolers aged 6-7. At the same time, the influence of the prophylaxis process of spinal deficiencies on the level of physical development of the contingent given by children was researched.
EFFICIENCY OF THE TRAINING PROCESS FOR SUSTAINABLE DEVELOPMENT OF MENTAL PSYCHOTIC POTENTIAL TO 12–13 YEAR-OLD HANDBALL PLAYERS IN THEIR TEAM-GAME SPECIALIZATION
Authors:   State University of Physical Education and Sport, Republic of Moldova, Verejan Ruslan
Published: June 2021

This article provides information on the experimental effectiveness of the training process to 12-13 year-old handball players in their formed team-game specialization. Currently, the competition calendar has radically changed, it has become more dense and intense for teams of different levels and ages with high demands on the results of the competition. And this, in turn, creates difficulties in the training process of athletes, allowing an excessive intensification of training sessions, with all the ensuing consequences. We believe that in this situation, in order to improve the sports training of handball players, at the present stage, it is necessary to use other possible reserves, which suggest, against the background of general training processes, the restructuring of the existing ways of organizing game capabilities, including an earlier age-related team-game specialization of athletes, in which their role, as an individual sports and technical characteristic, will be especially effective in competitive manifestations.

The methodology for determining the indicators of special physical and functional readiness of wrestlers, proposed by the authors, is distinguished by its simplicity and, at the same time, originality. The presence of a large number of discrete values makes the proposed method for determining indicators more sensitive and allows more accurate assessment of the results of maximum tests using loads of a specific nature of maximum and submaximal power, standard dosed load of a specific nature of submaximal power. It makes it possible to more accurately determine the degree of influence on the body of wrestlers of various qualifications, weight category and gender, the body's response to a specific load: heart rate, respiratory rate after exercise and the speed of recovery processes, indicators of physical performance and maximum oxygen consumption, as well as to carry out a comparative analysis efforts of wrestlers when performing physical activity of a specific nature of maximum and submaximum power. The data given by the authors allow to more effectively carry out operational and staged control over the process of training wrestlers of various styles, to make timely adjustments to the training plans of athletes

Precision calculations in the MSSM Higgs sector with FeynHiggs
Authors: Bahl Henning
Published: June 2021

In this talk I will give an overview of the status and recent developments of the FeynHiggs code. The main purpose of FeynHiggs is to calculate the Higgs boson masses and other physical observables in the Minimal Supersymmetric Standard Model (MSSM). To obtain an accurate prediction of the Higgs boson masses for low and high supersymmetry scales, state-of-the-art fixed-order and effective-field-theory calculations are combined. FeynHiggs provides not only a prediction for the Higgs boson masses, but also an estimate for the remaining theoretical uncertainties. I will highlight some of the recent improvements in the effective field theory calculation that are relevant for a light Higgs boson mass spectrum and in the presence of CP-violating phases. Finally, I will point out some exemplary phenomenological studies using FeynHiggs to constrain the MSSM Higgs sector.

Žádám o vyslovení absolutního zákazu Odbor zahraničního tisku jako součást informační politiky ministerstva vnitra
Authors:   Ústav pro studium totalitních režimů Česká republika, Havlík Adam
Published: June 2021

Studie se zabývá útvarem federálního ministerstva vnitra (FMV), který měl v 70. a 80. letech 20. století na starosti kontrolu zahraničního tisku, oficiálně objednávaného z ciziny československým státem nebo individuálně importovaného jeho občanům. Zahraniční tisk a šíření informací v něm obsažených představovaly pro vládnoucí Komunistickou stranu Československa (KSČ) potenciální riziko, a proto podléhal poměrně přísné kontrole. V rámci Státní bezpečnosti (StB) dohlížel nad tiskovinami směřujícími do země tzv. odbor zahraničního tisku (OZT). Jeho zaměstnanci pracovali mj. v utajení na poštách, kde prověřovali balíčky se zahraničními časopisy a knihami a závadné tituly vyřazovali z oběhu. Podíleli se tak na cenzuře a usměrňování toku informací, aby byl v souladu s představami vládnoucí KSČ. Studie se zaměřuje na mechanismy, na kterých stálo fungování tohoto odboru. Zároveň sleduje i personální složení OZT a s ním i sociální profil těch, kteří se podíleli na jeho chodu.
The Role of Korean Immigrant Churches in the Identity Development and Heritage Language Learning among Biracial Korean American University Students
Authors: Kim Hyein Amber
Published: June 2021

Korean immigrant churches are not only a place of worship, but a central place that provides cultural and social services as well. With Korean language education not widely available in US public schools, many Korean immigrant churches operate heritage language schools. This paper examines the experiences of biracial Korean American university students at Korean immigrant churches and church-based Korean heritage language schools; their experiences learning Korean before entering and during university; and how those experiences relate to their identities. Most participants perceived Korean immigrant churches as highly racialized and exclusive, and reported church-based Korean heritage language schools to lack resources, effective curricula, and cultural inclusion. The findings also show that the university setting was a space where participants felt safe to explore their Korean identities and learn the Korean language.

O uso de equipamentos híbridos tem trazido aumento das doses recebidas por pacientes de diagnostico em PET/CT. Existem atualmente várias metodologias dosimétricas, dificultando o estabelecimento de níveis de referências. Esse trabalho visa estimar as doses absorvidas e efetivas em exames oncológicos de PET/CT, comparando diferentes metodologias. Utilizou-se os fatores de dose publicados pela ICRP 106 para exames de 18F-FDG para a dosimetria PET; e para dosimetria do exame de CT foram comparadas três metodologias: software ImPACT, dosimetria termoluminescente (TLD) com simulador Alderson e metodologia recomendada pela AAPM nº96. As doses dos exames PET e CT foram somadas para obter a dose total do exame de PET/CT. Para dosimetria do PET os órgãos com maior dose absorvida foram a bexiga, o cérebro e coração. Para dose absorvida no CT as maiores diferenças foram para a pele, cérebro, tireoide e bexiga, sendo os órgãos críticos a tireoide e a pele. Apenas a metodologia da AAPM nº96 subestima a dose efetiva do CT quando comparada com a medida por TLD. Para o PET/CT, verificou-se que os órgãos críticos apresentam valores consideráveis de dose equivalente, recomendando a otimização dos protocolos e avaliação de risco. O presente estudo demonstrou que a simulação pelo ImPACT é o método dosimétrico que mais se aproxima da medida experimental realizada com TLD. Observa-se, ainda, a importância de investigar as doses equivalentes em órgãos ao invés de apenas as doses efetivas, como muitas vezes tem sido reportado na literatura.
ANÁLISE NUMÉRICA E EXPERIMENTAL DO COMPORTAMENTO AERODINÂMICO DA CARROCERIA DE UM ÔNIBUS RODOVIÁRIO
Authors: Rech Giovanni Matheus
Published: June 2021

Esse trabalho tem como objetivo avaliar os parâmetros aerodinâmicos de um modelo de ônibus rodoviário, comparando os resultados obtidos de simulação computacional via CFD (Computacional Fluid Dynamics), utilizando o software ANSYS FLUENT®, com aqueles obtidos de experimentação em túnel de vento. O veículo foi modelado em duas escalas diferentes, 1/42 e 1/24, juntamente com dois modelos de dimensões diferentes do corpo de Ahmed, utilizado nesse trabalho como uma comparação com a literatura. Para as análises do corpo de Ahmed foram utilizados seis modelos de turbulência, enquanto para o modelo do ônibus foi utilizado apenas o modelo κ – ε Standard. Na análise experimental foram realizados ensaios de distribuição de pressão e arrasto aerodinâmico (Cd ), variando a altura do vão livre entre a mesa automobilística e a superfície inferior dos modelos e variando também a velocidade do ar. Nos ensaios de pressão o coeficiente de pressão (Cp ) não houve uma variação significativa entre o ensaio experimental e o da análise via CFD para ambos os modelos.
A Curriculum of Ideology: Use and Abuse of Modern History Education in Russia and the United States
Authors: Tsyrlina-Spady Tatyana , Lovorn Michael
Published: June 2021

This paper examines the extents to which students in high school history classes in Russia and the United States are subjected to curricula, texts, images, and symbols that promote patriotic and nationalistic ideology. The authors performed a comparative content analysis of various commonly used Russian and American 20th century history textbooks. This analysis included an exploration of textual attention to ideological agendas, including the heroification of certain political and military figures, and led researchers to a series of implications regarding the impact of this manipulation of content on students’ general understandings of history, their country’s place in history, as well as an overall effect on their personality and character development. Most notably, analysis of recent textbooks in both countries revealed clear agendas intended to foster and promote national identity and patriotism.

True Relations: Discursive Imaginaries of Identity and Place in Canadian Curriculum and Pedagogy
Authors: Hasebe-Ludt Erika
Published: June 2021

This paper discusses the notion of ‘true relations’ in the context of contemporary Canadian curriculum studies and pedagogy. It focuses on the themes of identity and place, and their connections to multiliteracies in a culturally diverse society, the article points to a need for reimagining educational dialogues with attention to the truths and untruths that have shaped educational discourses in past and present precarious times. Drawing on the concept of métissage, and work by Canadian and transnational scholars in curriculum and pedagogy, this paper provokes and invokes the ethical importance of relational and truth-telling qualities in education.
Integrationsarbeit mit eingewanderten Jugendlichen mit VaKE (Values and Knowledge Education)
Authors: Patry Jean-Luc , Weyringer Sieglinde , Aichinger Kathrin , Weinberger Alfred
Published: June 2021

For a successful integration of young immigrants in the new culture and its values it is not sufficient that they acquire knowledge about the society; rather, moral and values education with respect to the justification of the respective values is required. We present an educational concept that permits to combine knowledge acquisition and moral education: “Values and Knowledge Education” (VaKE). The theoretical base and the practical steps are presented. Then a pilot study with a group of minor migrants about the topic of democracy and the most important results are described. The discussion addresses the question of applicability.
Impulse zum Umgang mit Kontingenz in der Politischen Bildung
Authors: Eschenbach Malte Ebner von
Published: June 2021

Im Beitrag werden Impulse Politischer Bildung im Umgang mit ‚kontingenten Grundlagen’ als Momente der Eröffnung von Pluralität und Vielfalt diskutiert. Im Zentrum der Überlegungen steht dabei die Reflexion auf Unterscheidungen als Ansatz Politischer Bildung, der auf einer kategorialen Tiefenschicht ansetzt und die Förderung von Demokratiekompetenzerwerb auf dieser Ebene situiert. Um die jeweiligen Voraussetzungen der Differenzsetzungen und -markierungen in den Blick zu bekommen, wird eine (ideologie-)kritische Positionierung Politischer Bildung vorgeschlagen. Durch die Kritik von Selbstverständlichem, die Infragestellung von Naturalisierungs- und Normalisierungsstrategien eröffnet sich ein Zugang, die verdeckten und latenten Setzungen von sozialen Kategorien und ihren verknüpften Differenzen intelligibel werden zu lassen. Dabei steht an dieser Stelle die Frage nach dem Auf- und Abbau sozialer Relevanz von Differenzen – un/doing difference – im Fokus der Betrachtung.
The Impact of Morphological Awareness on Vocabulary Knowledge of Advanced Chinese EFL Learners
Authors: Bian Xu , He Jin’e
Published: June 2021

The study explored the inter- and intra-relationship between two multi-dimensional constructs, morphology and vocabulary. Fifty five senior students from a Chinese university majoring in English were assessed on five variables: compounding knowledge, real-word derivational knowledge, pseudoword derivational knowledge, reading vocabulary knowledge and listening vocabulary knowledge. Using t-test, correlation and hierarchical regression, the study found that aural and written vocabulary knowledge was distinctive but related; real-word derivational knowledge correlated with both two facets of vocabulary knowledge; compounding knowledge and real-word derivational knowledge made unique contributions to performance on the listening vocabulary test.

Character Building or The Development of the Personality: An Innovative Methodological Platform in the Informational Educational Space
Authors: Berulava Mikhail Nikolaevich , Berulava Galina Alekseevna
Published: June 2021

Currently an acute crisis exists regarding the traditional methodological platform of the higher education system. Research continues with studies of individual facets of human personality without referring to new methodological realities. The dominant model of the University has remained unchanged for about 200 years. Today, however, the goals, means and agents of socialization are changing. In this essay, a new methodological platform for personality development is proposed and discussed, one which examines the role of behavioral stereotypes in the social and professional success of the individual.
