Published: December 2020

The long-term use of wetlands stresses wetland ecosystems and leads to degradation and C loss. This study explored an optimal remote sensing-multivariate linear regression model (RS-MLRM) for estimating wetland soil organic carbon (SOC) by using a combination of the measured SOC and above ground biomass (AGB) from 273 samples, textural features, spectral information, and a vegetation index calculated from Landsat-8 images using the Ningxia Basin of the Yellow River as the study area. To derive the optimal predictor model for SOC, these variables were regressed against the measured SOC. These were used to predict SOC and evaluate the contribution of wetland restoration and conservation projects to soil carbon sequestration and sinks on the Ningxia Basin of the Yellow River in early (2000 and 2005), intermediate (2010), and recent (2015) years. The results show that from 2000 to 2015, the project-induced contribution to C sequestration was 20.49 TC, with an annual sink of 1.37 TC. This accounted for 54.06% of the total wetland ecosystem C sequestration on the Ningxia Basin of the Yellow River. Moreover, there was a significant success of restoration and conservation projects regarding C sequestration. These restoration and conservation projects have substantially contributed to CO2 mitigation in the arid area.
Value Relevance of Accounts Receivable Factoring and Its Impact on Financing Strategy under the K-IFRS after COVID-19 from the Perspective of Accounting Big Data
Authors: Park Jung Min , Lee Hyoung Yong , Park Sang Hyun , Han Ingoo
Published: December 2020

This study investigates whether recognized accounts receivable (AR) factoring is more value relevant than disclosed AR factoring. After the adoption of the Korean International Financial Reporting Standards (K-IFRS), AR factoring is recognized as short-term debt, thus increasing firms’ leverage ratio. Using cross-sectional equity valuation regressions, we find that recognized AR factoring is value relevant, unlike disclosed AR factoring. Moreover, the market value of equity and AR factoring are more significantly correlated in highly leveraged firms than in less-leveraged ones. Accounting data are important from the perspective of big data. In the accounting industry as well, professionals started realizing the implications of big data. The COVID-19 pandemic has created a health crisis and wreaked havoc in an already-fragile global economy. Although there is no way to predict exactly what the economic damage from the COVID-19 pandemic will be, there must be widespread agreement that it will have severe financial impact on every company. Global financial markets have suffered dramatic falls due to the pandemic, and highly leveraged companies are in serious need of financing. While diving deeper, sound debt management and debt transparency are critical to ensure debt sustainability. Thus, companies would be willing to use AR factoring in order to overcome this financial status. This study also shows that highly leveraged firms decrease AR factoring after K-IFRS adoption.
Sensitivity Analysis of Envelope Design Parameters of Industrial Buildings with Natural Ventilation
Authors: Meng Xiaojing , Wei Beibei , Zhai Yingni
Published: December 2020

It is beneficial for designers to identify the most important design parameters of building envelopes. This study undertook sensitivity analysis integrated with EnergyPlus to assess the impacts of envelope design parameters for naturally ventilated industrial buildings. Sensitivity coefficients of six envelope design parameters for different internal heat intensities were analyzed and compared for buildings in the city of Xi’an, located in the cold climate zone of China. Our results showed that the heat transfer coefficient of the roofs had the most significant impact on indoor temperature. The weights were 32.29%, 33.71% and 30.71%, and the heat intensities were 5, 10 and 15 W/m3, respectively. The effect of the skylight-to-roof ratio was the second most sensitive. The impact of the solar absorptances of the walls and roof on the total number of hours was not sensitive. The results could be helpful for designers to efficiently form alternative design solutions in the design of new and retrofitting industrial buildings.
Sustainable Disaster Response Management Related to Large Technical Systems
Authors: Kinzhikeyev Sergey , Rohács József , Rohács Dániel , Boros Anita
Published: December 2020

Numerous investigations assess the technical, technological, and managerial aspects of disaster response related to large technical systems. This paper deals with the possibility of synthesizing these aspects in a disaster response methodology, thus combining the technical, technological methods, tools, and software with the art of management. Its objective is to develop a preliminary methodology that supports the response management decision making processes related to earthquake-damaged large technical systems. The introduced methodology is demonstrated with the example of railway systems. It utilizes a combination of (i) a probabilistic model of railway system damage caused by earthquakes, (ii) a Markov model related to the damage and recovery phases, (iii) a probabilistic model of aftershocks, (iv) a statistical model of secondary effects, (v) impact models of management support actions, and (vi) response process management supported by a Markov Decision Process. The simulation results validate the concept. Based on these research results, the authors recommend that the described preliminary response management approach be further specified and implemented in disaster management procedures.
Creutzfeldt–Jakob Disease with a Five-Year Clinical Course, Multicentric Cerebellar Prion Plaques and Prior History of Biopsy-Proven Primary Angiitis of the Central Nervous System: A Case for Iatrogenic Exposure?
Authors: Jeon Kristina , Joseph Jeffrey T. , Jansen Gerard H. , Peterson Anne , Knox J. David , Sim Valerie L.
Published: December 2020

Creutzfeldt–Jakob disease (CJD) is a rapidly progressive neurodegenerative disease that can arise spontaneously, genetically, or be acquired through iatrogenic exposure. Most patients die within a year of symptom onset. It is rare, affecting 1–2 per million per year, and the majority of cases are sporadic. Primary angiitis of the central nervous system (PACNS) is also rare, affecting 2.4 per million per year. We present a case of an unusually long clinical course of CJD, almost five years, which began with symptoms of apraxia. The patient had biopsy-proven PACNS 16 years prior to clinical presentation, and the site of biopsy was the left parietal lobe. Autopsy revealed multicentric prion plaques in the cerebellum, in the setting of normal genetic testing. The presence of plaques in the cerebellum, and prior neurosurgery, raises the possibility of iatrogenic exposure. We present the details of this case, including pathology from the original biopsy and final autopsy, as well as a review of relevant cases in the literature.

Koala retrovirus (KoRV) poses a major threat to koala health and conservation, and currently has 10 identified subtypes: an endogenous subtype (KoRV-A) and nine exogenous subtypes (KoRV-B to KoRV-J). However, subtype-related variations in koala immune response to KoRV are uncharacterized. In this study, we investigated KoRV-related immunophenotypic changes in a captive koala population (Hirakawa zoo, Japan) with a range of subtype infection profiles (KoRV-A only vs. KoRV-A with KoRV-B and/or -C), based on qPCR measurements of CD4, CD8b, IL-6, IL-10 and IL-17A mRNA expression in unstimulated and concanavalin (Con)-A-stimulated peripheral blood mononuclear cells (PBMCs). Although CD4, CD8b, and IL-17A expression did not differ between KoRV subtype infection profiles, IL-6 expression was higher in koalas with exogenous infections (both KoRV-B and KoRV-C) than those with the endogenous subtype only. IL-10 expression did not significantly differ between subtype infection profiles but did show a marked increase—accompanying decreased CD4:CD8b ratio—in a koala with lymphoma and co-infected with KoRV-A and -B, thus suggesting immunosuppression. Taken together, the findings of this study provide insights into koala immune response to multiple KoRV subtypes, which can be exploited for the development of prophylactic and therapeutic interventions for this iconic marsupial species.

Akhmeta virus is a zoonotic Orthopoxvirus first identified in 2013 in the country of Georgia. Subsequent ecological investigations in Georgia have found evidence that this virus is widespread in its geographic distribution within the country and in its host-range, with rodents likely involved in its circulation in the wild. Yet, little is known about the pathogenicity of this virus in rodents. We conducted the first laboratory infection of Akhmeta virus in CAST/EiJ Mus musculus to further characterize this novel virus. We found a dose-dependent effect on mortality and weight loss (p < 0.05). Anti-orthopoxvirus antibodies were detected in the second- and third-highest dose groups (5 × 104 pfu and 3 × 102 pfu) at euthanasia by day 10, and day 14 post-infection, respectively. Anti-orthopoxvirus antibodies were not detected in the highest dose group (3 × 106 pfu), which were euthanized at day 7 post-infection and had high viral load in tissues, suggesting they succumbed to disease prior to mounting an effective immune response. In order of highest burden, viable virus was detected in the nostril, lung, tail, liver and spleen. All individuals tested in the highest dose groups were DNAemic. Akhmeta virus was highly pathogenic in CAST/EiJ Mus musculus, causing 100% mortality when ≥3 × 102 pfu was administered.
BCG Provides Short-Term Protection from Experimental Cerebral Malaria in Mice
Authors: Witschkowski Julia , Behrends Jochen , Frank Roland , Eggers Lars , von Borstel Linda , Hertz David , Mueller Ann-Kristin , Schneider Bianca E.
Published: December 2020

Clinical and experimental evidence suggests that the tuberculosis vaccine BCG offers protection against unrelated pathogens including the malaria parasite. Cerebral malaria (CM) is the most severe complication associated with Plasmodium falciparum infection in humans and is responsible for most of the fatalities attributed to malaria. We investigated whether BCG protected C57BL/6 mice from P. berghei ANKA (PbA)-induced experimental CM (ECM). The majority of PbA-infected mice that were immunized with BCG showed prolonged survival without developing clinical symptoms of ECM. However, this protective effect waned over time and was associated with the recovery of viable BCG from liver and spleen. Intriguingly, BCG-mediated protection from ECM was not associated with a reduction in parasite burden, indicating that BCG immunization did not improve anti-parasite effector mechanisms. Instead, we found a significant reduction in pro-inflammatory mediators and CD8+ T cells in brains of BCG-vaccinated mice. Together these data suggest that brain recruitment of immune cells involved in the pathogenesis of ECM decreased after BCG vaccination. Understanding the mechanisms underlying the protective effects of BCG on PbA-induced ECM can provide a rationale for developing effective adjunctive therapies to reduce the risk of death and brain damage in CM.
The Roles of Osteopontin in the Pathogenesis of West Nile Encephalitis
Authors: Nazneen Farzana , Bai Fengwei
Published: December 2020

Osteopontin (OPN), a multifunctional protein encoded by the secreted phosphoprotein-1 (Spp-1) gene in humans, plays important roles in a variety of physiological conditions, such as biomineralization, bone remodeling and immune functions. OPN also has significant roles in the pathogenesis of autoimmune, allergy and inflammatory diseases, as well as bacterial, fungal and viral infections. West Nile virus (WNV), a mosquito-transmitted flavivirus, is the leading agent for viral encephalitis in North America. Recent progress has been made in understanding both the biological functions of OPN and the pathogenesis of WNV. In this review article, we have summarized the current understanding of the biology of OPN and its vital roles in the pathogenesis of WNV encephalitis.
The Relation between Tourism and Economic Growth: A Case of Saudi Arabia as an Emerging Tourism Destination
Authors: Jamel Lamia
Published: December 2020

This paper examines empirically the relation between tourism and economic growth in Saudi Arabia. The authors try to justify how tourism contributes to the economic growth of Saudi Arabia. There are applied descriptive statistics, unit root test, VAR model and Granger Causality test as an econometric methodology to examine the connection between tourism and economic growth in Saudi Arabia for the annual data in the period from 1990 to 2018. The main empirical results of the study find out that tourism affects positively the economic growth in Saudi Arabia. Also, there is found a positive nexus among tourism and economic growth. Furthermore, CO2 emissions and financial development impact positively the tourism sector, while trade openness predicts a negative effect on tourism. Additionally, CO2 emissions, financial development, and trade openness have a positive impact on economic growth in Saudi Arabia. Finally, the Granger causality test provides evidence of bidirectional nexus between tourism and economic growth in Saudi Arabia. This paper contributes to the current research by explaining the causal nexus among tourism and economic growth in Saudi Arabia during the period from 1990 to 2018, applying a vector autoregressive model and Granger Causality.
Institutional Regulation of the Healthcare System in the Context of Spreading COVID-19 in the Russian Federation
Authors: Rusova Violetta , Mkrtumova Anait
Published: December 2020

The modern era of globalization creates specific socio-ecological conditions for the existence of the world human community, which, in turn, determine the singularity of the epidemiological behaviour of many infectious diseases. The year 2020 has challenged the humanity with a pandemic that is rapidly spreading around the world. Global relationships are fraught with global epidemiological problems. Such manifestations of globalization as intensified international migration of population, roaring international trade in agricultural products, domestic and wild animals and birds, food, raw materials and goods, development of high-speed transport, turn the world into a single global socio-ecological epidemiological system, in which all processes are interconnected and mutually dependent. The purpose of this research is to study and analyse the system of institutional regulation of the health system in the context of a pandemic. The study used such methods as the analysis method, analogies, comparisons, observations, as well as statistical methods to analyse various indicators necessary for research. Using the above methods, a large amount of literature, legislation, regulatory and institutional regulations on this issue was analysed, some existing indicators were summarized, and a conclusion was made about the process of institutional regulation in an unfavourable epidemiological situation. As a result of the study based on a large number of official documents, it was concluded that measures were taken in the Russian Federation to counteract the active spread of a new coronavirus infection. Implementation of the state policy on preventing the spread of the pandemic resulted in no high mortality rate from new coronavirus infection compared to other world states. It should be noted that due to the federal structure of the country, the heads of regions independently decide on the regulation of mechanisms to counter the spread of infection on the territory of the subject. In this regard, it is not possible to promptly update information on the effectiveness of the measures taken. Currently, the risk-based approach described in the article is a mechanism for studying the epidemiological situation, which allows determining the risk factors that affect it and, on this basis, to rank epidemiological problems by their degree of importance. Due to the fact that the pandemic as a new virus was an unexpected risk, the clinical picture remains blurred, but the institutional form of state regulation is fused to protect the rights of citizens to health care under conditions of the pandemic.
The Green Deal Policy for Renewable Energy: A Bibliometric Analysis
Authors: Ziabina Yevheniia , Pimonenko Tetyana
Published: December 2020

The industry attention to the environment has been reducing lately, leading to irreversible climate change, reaching the limit of mining, and critical indicators of СО2 emissions. That is why the EU has launched a new Green Policy which includes strategic directions for energy efficiency and which is expected to restore biodiversity and slow down the pace of climate change. Thus, on December 11, 2019, there was held the presentation of the “European Green Course”, the main targets of which are to increase the level of energy saving by creating closed cycles in the economy; to minimize greenhouse gas emissions by 2050; to form biodiversity and climate neutrality. Accordingly, countries that accept the terms of the green deal policy need to review all aspects of their economy, from energy production to food consumption, from industry to transport and construction. The purpose of the article is to analyse publications in order to identify public’s awareness of radical changes in economic and ecological spheres. The article provides a bibliometric analysis of research in the field of green deal policy, energy conservation and energy efficiency through the introduction of renewable energy sources. The authors selected 337 papers which were published in 1999-2019. Scopus provided the database for analysis. By means of VOSviewer the results of bibliometric analyses were visualized in a definitions map. It allowed identifying six clusters that combine 131 terms. As a result of the research, the connection between the terms – renewable energy sources and energy saving – was revealed with the help of the constructed bibliographic map.

Published: December 2020

Background

Patients on maintenance hemodialysis are particularly vulnerable to infection and hospitalization from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to immunocompromised patients and the clustering that occurs in outpatient dialysis units, the seroprevalence of COVID-19 antibodies in this population is unknown and has significant implications for public health. Also, little is known about their risk factors for hospitalization.

Methods

Three outpatient maintenance hemodialysis units affiliated with a major teaching hospital in the New York area were studied. We determined rates of SARS-CoV-2 positivity via nasopharyngeal, real-time, reverse-transcriptase PCR (RT-PCR); SARS-CoV-2 IgG seropositivity; hospitalization; and mortality.

Results

Of 367 patients, 28% had either SARS-CoV-2 seropositivity or PCR positivity. Prevalence across the three respective units was 7%, 32%, and 70%. Those who were either antibody or PCR positive were significantly younger (65 versus 69 years, P=0.05), and had a higher prevalence of Black race (43% versus 30%, P=0.001) and Hispanic ethnicity (32% versus 12%, P<0.001) compared with those who tested negative. Higher positivity rates were also observed among those who took taxis and ambulettes to and from dialysis, compared with those who used personal transportation. Antibodies were detected in all of the patients with a positive PCR result who underwent serologic testing. Of those that were seropositive, 32% were asymptomatic. The hospitalization rate on the basis of either antibody or PCR positivity was 35%, with a hospital mortality rate of 33%. Aside from COPD, no other variables were more prevalent in patients who were hospitalized.

Conclusions

We observed significant differences in rates of COVID-19 infection within three outpatient dialysis units, with universal seroconversion. Among patients with ESKD, rates of asymptomatic infection appear to be high, as do hospitalization and mortality rates.

Formalization and productivity: firm-level evidence from Viet Nam
Authors: Lay Jann , Tafese Tevin
Published: December 2020

Using a firm-level panel dataset on private small- and medium-sized enterprises (SMEs) in Viet Nam’s manufacturing sector, this paper examines productivity dynamics of formal and informal firms. We decompose productivity changes into changes within and between formal and informal firms. We assess the contributions of firm entry and exit as well as informal–formal transitions. Our results show that productivity is considerably lower and misallocation more prevalent in the informal than in the formal sector. Yet, formalizing firms in Viet Nam make an important contribution to aggregate productivity growth among manufacturing SMEs, growing faster than other firms and increasing efficiency. We identify two ‘regimes’ of formalization. Until early 2010, more productive (previously) informal firms formalize. Policy changes and accelerated formalization then alter the characteristics of formalizers, as less productive firms become formal. While this formalization wave depresses average formal total factor productivity growth, the overall productivity effect is positive.

Authors: Califa Juan Sebastián
Published: December 2020

En este artículo se abordan las luchas del movimiento estudiantil de la Universidad Nacional de Rosario, entre los golpes de Estado de 1966 y 1976. El trabajo se propone retratar con precisión la evolución de las formas de acción, los protagonismos de las agrupaciones implicadas y las alianzas tejidas por el movimiento estudiantil rosarino para, finalmente, trazar y explicar los ciclos de conflictividad detectados al observar los valores que arrojan ciertas variables y las relaciones plausibles de establecer entre sí. Al operacionalizar el concepto de enfrentamiento social, a partir del registro de una importante base de datos construida fundamentalmente con periódicos de la época, se arrojan algunas conclusiones y, al mismo tiempo, se revisan otras ideas sobre el estudiantado rosarino y su activismo. Con el análisis de este caso, se pretende avanzar en una labor más amplia de caracterización del movimiento estudiantil argentino en dicho período.
Promoción y Protección de derechos de la Niñez. Nuevos desafíos de intervención en el campo educativo

Published: December 2020

En este trabajo nos proponemos presentar cómo en el caso de la Ciudad Autónoma de Buenos Aires (CABA) y la Provincia homónima se han reformulado los fundamentos de la atención de la infancia, otorgando especial atención al campo educativo. Las reformas iniciadas desde la década de los 90 evidencian una tensión persistente entre dos tendencias de distinto cuño. Por un lado, una perspectiva denominada neoliberal que promovió el desincentivo a la intervención público-estatal, que algunos autores consideran como pos bienestaristas y, por otro lado, una ampliación de las normas que desde la perspectiva de derechos promovió la ampliación de aquéllos en el campo de la infancia. Ambas tendencias conviven y tensionan el campo de las intervenciones, especialmente aquellas de las que los/ as trabajadores/as sociales son parte.
Tensiones y retos sobre la mujer rural y su participación en la construcción de paz en Colombia
Authors: Bueno Ana Marcela , Suarez Puentes Karin Viviana
Published: December 2020

La mujer rural y sus dinámicas de participación han sido temas abordados en el marco de los estudios de las ciencias sociales desde los años 90, época en la cual la política pública visibilizó la relevancia de esta población en la producción de la tierra. Sin embargo, el reconocimiento del papel que desempeñan en la sociedad a través de los diferentes ámbitos ha sido subvalorado. Hoy en Colombia, con la firma del acuerdo de paz, reconocer el rol que puede cumplir la mujer en el territorio rural tiene sentido por la relevancia que cobra su aporte como reproductora de una sociedad que renace, aprovechando sus experiencias en el ámbito de la organización y la participación social. Con el fin de comenzar a construir un marco de referencia sobre esta temática, se realizó una revisión de investigaciones nacionales e internacionales publicadas desde el año 20061 buscando dar cuenta de los estudios realizados y el estado del conocimiento sobre la participación de las mujeres rurales en la construcción de paz en Colombia.

La Calota de Ameghino:
Authors: Schávelzon Daniel
Published: December 2020

Se ha publicado el fechado de Carbono 14 de un fragmento de cráneo estudiado por Florentino Ameghino a finales del siglo XIX. A Ameghino le sirvió para afirmar su teoría sobre el origen del hombre en las pampas al que le otorgaba un millón de años y el ser parte fundamental de la cadena del origen de la humanidad. Hubo polémicas, pero el tema quedó cerrado cuando Ales Hrdlicka y Bailey Willis en 1912 demostraron que estaba basado malas interpretaciones. El cráneo había llegado a un nivel geológico discutible y por causas no naturales.El hallazgo había sido hecho en un sitio que hasta poco antes estaba dentro del agua del Río de la Plata, cerca de 400 metros de la orilla antigua, lo que ayudaba al antiguo fechamiento. Al ubicarlo ahora en una fecha hacia 1720 dC resulta interesante construir hipótesis sobre su presencia allí (Politis y Bonomo 2011), en lo que hubo en el lugar y en las condiciones en que fue encontrado; es decir su contexto. Los datos de otros hallazgos frente a Buenos Aires ayudan a repensar el tema, y la revisión cartográfica y  documental permite entender que afirmaciones hechas tanto por un bando como otro no tomaron en cuenta los eventos de alteración del sitio.

Published: December 2020

Este artículo está dedicado a hacer una reseña sobre el final del sitio La Boca (Departamento de San Jerónimo, Provincia de Santa Fe, Argentina). La destrucción lateral de la terraza en donde estuvo emplazada la reducción franciscana de San Bartolomé de los Chaná por una bajante extraordinaria del río Coronda, uno de los brazos del río Paraná en su Delta inferior, afectó el depósito arqueológico que contenía una potente distribución cerámica indígena y europea así como distintos elementos que documentaban su existencia. El final de un sitio arqueológico es siempre una posibilidad materialmente sustantiva pero cuando efectivamente ocurre es necesario un análisis reflexivo centralizado en sus implicaciones tanto teóricas como prácticas.
Investigaciones arqueológicas en la casa del primer intendente de la localidad de Puan, provincia de Buenos Aires
Authors: Panizza María Cecilia , Oliva Fernando
Published: December 2020

En este trabajo se aborda el estudio de los restos materiales correspondientes a la casa del primer intendente de la localidad de Puan. Esta residencia fue construida a fines del siglo XIX y posee la particularidad de estar ubicada en la isla de Puan, en la laguna homónima, en el extremo occidental de Sistema Serrano de Ventania, dentro del sector sur del Área Ecotonal Húmedo Seca Pampeana. Actualmente la isla es una reserva municipal natural y cultural, pero a pesar de estar protegida pre- senta importantes consecuencias de las actividades humanas, producto de su pro- ximidad al actual casco de la ciudad cabecera del distrito. Desde el año 1987 hasta la fecha, se desarrollaron investigaciones arqueológicas vinculadas a la ocupación prehispánica de la isla, que determinaron la identificación de cuatro sitios arqueo- lógicos en distintos puntos de la isla y dos concentraciones de materiales en los márgenes de la laguna, cuya antigüedad alcanza aproximadamente 3300 años A.P. Por otra parte, en el extremo noroeste de la isla se localizan evidencias importantes relacionadas con la historia institucional del Municipio, entra las cuáles se puede mencionar las estructuras pertenecientes a la casa de Rómulo Franco, el primer intendente de Puan. Esta construcción fue abandonada en el siglo XX, dada las dificultades que presenta la isla para sostener una población, aún pequeña, en con- diciones climáticas extremas, lo cual también ha llevado a que varíe su fisonomía, convirtiéndose en una península en determinados momentos históricos. En la loca- lidad circulan relatos orales acerca de posibles entierros de armas u otros elementos pertenecientes a la época de Rómulo Franco, lo cual agrega un contenido místico al conjunto de evidencias de esta época.

El sitio “Baño de Mandinga” Potencialidad arqueológica de un basural periférico
Authors: Volpe Soccorso , Fernetti Gustavo
Published: December 2020

La expansión urbana de Rosario y su condición inmigratoria-aluvional entre 1880 y 1920, generó una ciudad dispersa, con un centro compacto y espacios suburbanos que para la época aún se dirimían entre lo rural y lo urbano. Esa condición dinámica (y ambigua) generó espacios intermedios: interfaces urbanísticas, lugares híbridos en el sentido de “no ciudad”, habitados y a la vez socialmente rechazados como espacios negativos. Estos lugares con frecuencia estaban destinados a baldíos sin población, pero en algunos pocos casos, se establecieron poblaciones marginadas y actividades emergentes, incluso industriales o fabriles. Para el caso de este trabajo, el “Baño de Mandinga” (c. 1880-1912, sitio MD) podría constituir un caso específico de convivencia entre una población radicada y la deposición de basuras, junto con actividades industriales y ferroviarias. El objetivo de este trabajo es aproximarse a un sitio arqueológico, tan complejo como históricamente oscuro, pero que podría ayudar a conocer la dinámica social rosarina entre finales de siglo XIX y principios del XX.
From Disaster to Resilience

Educational Design-Build (EDB) has exploded in popularity over the last twenty years especially since it was reinvigorated by Samuel Mockbee’s Rural Studio at Auburn University in 1994. Although they may be unique to many practicing architects today (who often say “I wish I had a project I actually got to build in School”), EDB programs and projects are found at over 2/3rd’s of the 154 schools of architecture in North America today. These projects and experiences have come to be expected by today’s students who want to be involved from the initial conceptual design to installing the kitchen sink. EDB at its best, combine’s civic-minded, design education with project-based real-life experiences.

Reviews of low-temperature atmospheric pressure plasma for studying hemostasis and international standardization
Authors: Sakakita Hajime , Shimizu Tetsuji , Ikehara Yuzuru
Published: December 2020

Using current surgical hemostasis technologies, the scarring that results from cauterization limits the efficacy of surgery; therefore, a method that controls bleeding without scarring tissue is required. In this regard, low-temperature atmospheric pressure plasma (LTP) has been studied as a minimally invasive technology. There are several reports regarding induced platelet aggregation, fibrin polymerization, hemolytic coagulation of red blood cells, and serum protein aggregation following LTP treatment of the blood. However, details of the interrelationships between “plasma quality such as oxygen radicals and electric properties” and “coagulation and aggregation” are not fully understood. It is important to clarify the differences between plasma qualities by analysis. However, in the case of protein aggregation, electric effects may be a key factor. Conversely, LTP devices manufactured for hemostasis are subject to a new international standard (IEC 60601-2-76), which provides basic safety and essential performance specifications.

Ectopia cordis is a very rare form of congenital malformation in which the heart is located outside the thorax, partially or totally. This abnormally located heart may be found in different anatomical locations, such as thoracic, abdominal, thoraco-abdominal, cervical or cervicothoracic. In majority, the heart projects outside the chest through a breach in sternum. This unique rare case report presents a male infant born at a peripheral hospital which was later referred to out tertiary care cardiac research institute. In our case thoracic ectopia was associated with complex cardiac anomalies. The baby had good APGAR scores at birth. The baby died 10 days after birth as a result of cardiac failure and septicaemia.

Introdução: A utilização de oxigênio (o2) de suporte é um recurso terapêutico comumente utilizado em pacientes graves, porém assim como usada para cura, se utilizado de maneira excessiva, pode acarretar riscos a vida. A oferta em demasia chega a acometer 50% dos pacientes nas Unidades de terapia intensiva. A observação de indicadores para controle do o2 ofertado é crucial para diminuição da hiperoxemia em pacientes críticos, logo diminuindo a mortalidade dos mesmos nas Unidades de terapia intensiva como demonstrado em estudos diversos. Objetivo: Apresentar os indicadores de controle de O2 ofertado para evitar a hiperoxemia. Método: Estudo de caráter Observacional Comparativo de dados, com base no caderno de monitoramento dos fisioterapeutas de um Hospital Público de Referência na Amazônia. Como critério de inclusão foram aceitos todos os valores referentes aos pacientes internados na UTI em uso, sendo considerados para hiperoxemia os valores acima de 10% da PaO2 recomendado para idade. Foram excluídos do estudo os valores referentes aos pacientes internados na enfermaria, DPOC, respirando espontaneamente em ar ambiente ou com FiO2 à 21%, nebulização com O2 sem critério de indicação, hipoxemia por shunt ou espaço morto. Resultados e Discussão: O estudo mostrou a importância da utilização controlada de O2 em pacientes nas unidades de terapia intensiva, apresentando como principais resultados uma diminuição do consumo médio de oxigênio ofertado, pela queda da média mantida em uso de Fio2, assim como o declínio no índice de hiperoxemia dos valores analisados. A presença do fisioterapeuta 24h na unidade de terapia intensiva é de extrema importância para diminuição do consumo de oxigênio, assim como a do Fisioterapeuta Diarista, pois o mesmo com sua avaliação identifica a necessidade de implementação de rotinas e normas de controle, mantendo a educação continuada frente à conduta planejada para cada caso, sendo neste, frente ao uso de 02 para cada aplicação terapêutica. Tais dados sugerem que o fisioterapeuta pode gerar uma diminuição no índice de mortalidade de pacientes com hiperoxemia e proporcionar uma economia nos gastos hospitalares. Conclusão: Este estudo mostrou que este indicador trouxe benefícios à rotina, porém há necessidade de melhor entendimento e uso do o2, com objetivo de maior qualificação na assistência ao paciente. Podemos sugerir a inclusão do fisioterapeuta diarista, pois o mesmo preserva a assistência segura ao paciente, minimiza erros de conduta, busca melhorias no atendimento e realiza educação continuada.
Partnerstwo Wschodnie jako kluczowy element polityki zagranicznej państw bałtyckich
Authors: Kuczyńska-Zonik Aleksandra
Published: December 2020

One of the foreign policy priorities of Lithuania, Latvia and Estonia is to support the Eastern Partnership (EaP) programme as a strategic dimension of the European Neighbourhood Policy and a key element of stability and economic progress in Eastern Europe. The Baltic States are of the opinion that relations with the EaP states should remain one of the priorities of the Eastern Dimension of the EU’s foreign policy. The cooperation of the Baltic States with the Eastern partners results both from the ambitions and willingness to strengthen international prestige and role, as well as the need to ensure security and stability of the region in the context of Russia’s aggressive policy. The 10th anniversary of EaP is an opportunity to assess the contribution of Lithuania, Latvia and Estonia to the development of the programme and to discuss the future of cooperation.
Ukraina w Partnerstwie Wschodnim: osiągnięcia i perspektywy
Authors: Bazhenova Hanna
Published: December 2020

May 2019 marked the 10th anniversary of the launch of the European Union’s Eastern Partnership initiative, which encourages democratic reforms in Azerbaijan, Armenia, Belarus, Georgia, Moldova and Ukraine and the strengthening of the relations and cooperation between these countries and the EU. During this period, significant results were achieved in terms of political association, economic relations and regulatory convergence. Thanks to this initiative, Moldova, Georgia and Ukraine signed association and free trade area agreements (DCFTAs) and achieved visa-free travel. One of the main drawbacks of the programme at this stage is that it does not provide for a differentiated approach towards partner countries and deeper cooperation with those already signatory to Association Agreements. The anniversary of the Eastern Partnership encourages to take stock of the results of the initiative and identify perspectives for its further development. The aim of this article is to identify the main achievements of the Eastern Partnership from the perspective of Ukraine’s priorities and interests, as well as to propose a new effective model of relations between Ukraine and other partner countries with the EU under this initiative. The text sets out and analyses the main stages of the cooperation between Ukraine and the EU in the years 1991–2019, especially the participation of Ukraine in the European Neighbourhood Policy and the Eastern Partnership. The article shows that the Eastern Partnership policy and its implementation mechanisms need a structural review and differentiated, individual approaches that would meet the needs, expectations and interests of all the parties. If the EU intends to continue building mutually beneficial relations with its eastern neighbours, it should not only maintain the existing initiative, but also adapt it effectively to the challenges of the present. The EU should therefore develop a sufficiently attractive and effective model of cooperation to support pro-European reforms in its partner countries.
