Ausreichend Raum für die Windenergienutzung an Land. Ein Vorschlag für neue regulative Rahmenbedingungen
Authors: Von Seht Hauke
Published: November 2021

In the course of the upcoming further restructuring of the energy system in Germany, it will be necessary to gradually provide additional areas for the use of wind energy on land. However, the current regulatory framework shows deficits which make the corresponding planning considerably more difficult and delay. Therefore, legislative changes are proposed in this paper to solve the problem. The resulting new dynamic control approach relies on gradual, optimized expansion values in the Renewable Energy Sources Act, on which the basic requirements in the Spatial Planning Act are based. The latter contain minimum requirements for regional planning priority areas – based on regular analyses to be introduced by the Bundesamt für Bauwesen und Raumordnung. If these values are adhered to, an encouraged partial deprivation of privilege in the building code would take effect, by means of which complex and error-prone concentration zone planning can be dispensed with in corresponding regions. At the same time, a change is proposed to accelerate the process, on the basis of which a permit for wind turbines in priority areas can be carried out in a legally secure manner, even in the case of opposing, as yet unadjusted municipal concentration zone plans.

Approaches to integrate land-use and transport planning. Analysing the political dimension of integrative planning
Authors: Levin-Keitel Meike , Reeker Irina Kim
Published: November 2021

Assuming that mobility behaviour of citizens can be partially influenced by certain spatial structures, the integration of land-use and transport planning seems to be a key aspect of a transition towards sustainable mobility. Such an integrated planning approach is characterised, for example, by increased cross-sectoral interaction, softened institutionalised boundaries between the two sectors of land-use and transport planning as well as cross-sectorally shared goals. However, this often-articulated claim for integration remains unclear in its implementation. Hence, this article presents a conceptual framework within the three dimensions of policy, polity and politics to grasp what integration comprises in its different aspects. The two German cities of Dortmund and Hanover serve as case studies. It appears that informal interaction (politics) between the two sectors acts as a necessary precondition whereas true political will and shared targets (policy) are needed to really initiate the process towards integration. Ultimately, an approach is fully integrated if the institutional design (polity) is adapted in terms of hierarchical coordination and largely removed sectoral boundaries.

Published: November 2021

Due to global changes and changes in land use, ecosystems and their services are increasingly affected. Against this background, it is questionable how ecosystems and the services they provide can be better and sufficiently taken into account in land-use planning as well as spatial development in Germany. Currently little chance is seen to establish new ecosystem service-based processes that would be comprehensively integrated in the spatial planning practice in Germany. However, modernisation of formal and informal planning instruments is conceived in a long-term perspective. The ecosystem service approach can essentially contribute to this modernisa[1]tion methodically as well as conceptually. Therefore, this paper discusses possibilities how to integrate the ecosystem service approach in formal spatial planning in a short to medium term and which societal and ecological added value can be generated. Chances and risks of different implementation options will be discussed and specific approaches outlined.
Privatanleger als Beschleuniger urbaner Wohnkrisen. Bedeutung und Motive von Privatanlegern auf Wohnungsmärkten abseits der Metropolen am Beispiel Salzburg
Authors: Van-Hametner Andreas
Published: November 2021

So far, the increased emergence of financial investments on the housing markets has mainly been examined in metropolises or on a national level. Research focused primarily on institutional actors. The investigation of financial investments in housing space in cities below the metropolitan level and by individuals has so far been neglected. In the present study, I therefore focus on the manifestation of financial investments of private investors in housing markets outside the metropolises using a mixed-method approach of quantitative land register and data analysis as well as qualitative expert interviews. The paper shows that apart from the metropolises, the utilization of housing into an investment object is mainly carried out by private actors. They invest less out of speculation and in the expectation of an increase in value, but rather for private retirement or family provision and, above all, to secure value. This form of investment in housing also leads to serious consequences for other market players. The entire housing market is gradually focusing on this new type of investor. Real estate has therefore increasingly become a form of investment for many.

Authors: Audina Salsabila , Bakhtiar Arfan
Published: November 2021

PT. Mitsubishi Chemical Indonesia merupakan perusahaan yang bergerak di bidang industri polyester yang memproduksi Purified Terephthalic Acid (PTA) terbesar di Indonesia. PTA adalah suatu senyawa yang tidak tersedia di alam yang dibuat dari sintesa kimia. Terdapat auxiliary raw material yang diperlukan untuk membantu proses produksi PTA agar dapat berjalan dengan lancar, seperti Hydrobromic Acid (HBr) dan Soda Ash Dense (Na2CO3). Perusahaan belum memiliki jumlah safety stock padahal perusahaan harus mengendalikan persediaan auxiliary raw material agar dapat menghindari kekurangan dan kelebihan bahan baku yang menyebabkan perusahaan dapat mengeluarkan biaya lebih banyak. Hasil perhitungan memperlihatkan bahwa metode min-max stock menunjukan jumlah safety stock bahan baku Hydrobromic Acid yaitu sebesar 17,5 ton dan untuk Soda Ash Dense yaitu sebesar 5,41 ton. Penentuan jumlah persediaan antara kebijakan perusahaan dengan hasil perhitungan metode min-max stock memiliki beberapa perbedaan. Dari perbedaan tersebut, perusahaan dapat menghemat total biaya persediaan sebesar Rp 7.550.000,00 untuk Hydrobromic Acid dan Rp 11.221.224,16 untuk Soda Ash. Frekuensi pemesanan yang terlalu sering dengan ukuran pemesanan yang besar menyebabkan total biaya persediaan menjadi tinggi. Dari hasil tersebut perusahaan perlu menerapkan metode min-max stock untuk mengendalikan persediaan bahan baku supaya dapat menghemat biaya pengeluaran. Abstract[Inventory Control Analysis of Aux Raw Material Using Min-Max Stock Method in Mitsubishi Chemical Indonesia Company] Mitsubishi Chemical Indonesia is a company engaged in the polyester industry that produces the largest Purified Terephthalic Acid (PTA) in Indonesia. PTA is a compound that is not available in nature, so it is made by chemical synthesis. There are auxiliary raw materials that are needed to help the PTA production process, so it can run well, such as Hydrobromic Acid (HBr) and Soda Ash Dense (Na2CO3). The company don’t have the safety stock even though the company should control the aux raw material inventory to avoid the company to run out of stock or overstock, that causes the company to spend a lot of money. The calculations result shows that the amount of the safety stock for Hydrobromic Acid is 17.5 tons and for Soda Ash is 5.41 tons. The determined number of inventories between company policy and the calculation of the min-max stock method have several differences. From those differences, the company can save the total inventory cost amounted at IDR 7.550.000,00 for Hydrobromic Acid and IDR 11.221.224,16 for Soda Ash. High frequency of orders with a large order size can cause the total inventory cost to be high. From that result, the company needs to apply a min-max stock to control inventory and to save money on expenses.Keywords: inventory; min-max stock method; out of stock; overstock; TIC

Published: November 2021

The risk of Musculoskeletal Disorders (MSDs) can occur in a variety of occupations including in traditional jewelers. The complaint is caused by an awkward position during work activities. The study aims to identify complaints of Musculoskeletal Disorders (MSDs). This study used qualitative approach through in-depth interviews on 5 key informants and 2 key expert informants and ergonomic risk determination referring to the BRIEF method. The results showed that all informants experienced complaints of the upper neck, lower neck, right shoulder, back, right elbow, right upper arm, and right forearm. Measurements through the BRIEF sheet show that complaints on the left and right elbows, left and right shoulders, neck, and back include high category ergonomic hazards while complaints on the hands and wrists of the right include moderate category ergonomic hazards. High risk of Musculoskeletal Disorders (MSDs) is found at all stages of work (smelting, grinding, posturing, jewelry formation, and gilding). Therefore, workers are recommended to perform muscle relaxation for (8-12 seconds) every half hour.
„Ekstaza” czy „admiracja”? Ikonografia obrazu św. Franciszka z Muzeum Diecezjalnego w Siedlcach w kontekście wymowy wybranych płócien z serii franciszkańskiej El Greca
Authors: Kossowski Maciej Dariusz
Published: November 2021

The widely adopted title of “Ecstasy of St Francis”, a painting at the Diocesan Museum in Siedlce, was introduced in literature in 1966 based on the typology developed by José Gudiol. The designa- tion continues to be used until today. However, the significance and the purport of the title has not been confronted with the representation, especially given the current knowledge about its details. No attention has been paid so far to the nature of the stigmata, nor have any conclusions been drawn from the arrangement of the fingers or the depiction of bone remains, their pattern and placement. An analysis of those motifs changes the previous interpretation of what the work seeks to convey. The paper also cites arguments in favour of amending the current dating, from 1578-80 to the early seventeenth century.

Squatter Settlement: Costs and Contributing Factors in Jimma Town, Oromia National Regional State, Ethiopia
Authors: Akirso Nega Abera
Published: November 2021

Urbanization and urban growth are considered as a modern way of life which manifests economic growth and development in many countries. On the other hand, it yields a number of evils, especially unplanned (squatter) settlement. The study conducted on the area of squatter settlement in Jimma town is aimed to explore the socioeconomic factors contributing for squatter settlement and its effect on social, economic and institutional conditions of settler and development of the town. The study was guided by qualitative research approach and employed cross-sectional and phenomenological design in which primary data required for the analysis was collected through key informant interview, focus group discussion, non-participant observation as well as secondary data from document and analyzed by thematic analysis. The findings of this study revealed that, the root cause identified for squatter settlement is shortage of residential house and its consequential high price of house rent, the need of holding large plot of land and inefficient land administration system. Other findings indicated that squatter settlement incur costs on both the government and the squatter. Squatter settlement creates fear and dearth of confidence on the land they hold illegally, poor infrastructure due to lack of government interventions and low social service delivery, and social distress within the community. The study also found out that squatting displaces the host ex-farmers from their farmland and leads to consequent poverty and livelihood disasters. It is recommended that, political will in accessing residential land and financial commitment of the government is required. Active participation of the public and abiding legal procedures in accessing residential land is vital.
The Fear of COVID-19, Demographic Factors, and Substance use in a Multinational Sample Amid the COVID-19 Pandemic
Authors: Ogueji Ifeanyichukwu Anthony , Asagba Rachel Bolaji , Constantine-Simms Delroy
Published: November 2021

The global pandemic caused by the coronavirus disease 2019 (COVID-19) had mental health consequences such as fear. Scholars have argued that when people are fearful, they may use substances to escape from fear, and demographic variables can have implications on how to target interventions to people. To date, little is known about how the fear of COVID-19 and demographic factors may contribute to substance use amid the COVID-19 pandemic. From 3 June to 10 June 2020, a cross-sectional study was conducted with 202 residents (Mean age = 41.77 ± 11.85; age range = 18-70 years) in 14 countries. A standardized questionnaire was utilized for data collection, SPSS (version 22.0) was utilized for data analysis, and p < .05 implied statistical significance. Descriptive statistics revealed that residents in Canada scored the highest mean score in the fear of COVID-19 scale, while residents in Australia scored highest in the substance use scale. Further, fear of COVID-19 had a negative nonsignificant relationship with substance use (r = −.07; df = 200; p > .05). Males (Mean = 18.21) scored significantly higher than females (Mean = 14.06) in substance use [t (200) = 1.9; p < .05]. The younger age group (18-28 years) scored the highest mean score in substance use compared to older age groups (29-39 years, 40-50 years, 51-61 years, and 62-72 years); however, it was not significant [F (4, 197) = 2.04; p > .05]. These data contribute to informing future studies that add more questions regarding how different variables may contribute to substance use during subsequent waves of the COVID-19 pandemic.

Published: November 2021

Dam construction is one of the most popular solutions for managing water resources. In recent years, changes in patterns of regional seismicity associated with large impoundment dams have raised concerns among environmentalists. In this study, five large dams located in Iran were studied from this perspective. The Gutenberg-Richter, linear regression and T-test were used to examine the seismic changes in the radius of 100 km of each of the dams during a twenty-five-year period before and after the construction of the dams. The results revealed that the seismicity level and relative density of large and small earthquakes in three of these dams have increased after dam construction. A significant difference between the magnitude of earthquakes, as well as the number of earthquakes before and after the construction of dams in the region, was recognized. However, the results of the T-test statistical analysis indicated that the mean depth of the earthquakes and their distance from the dams before and after construction have not changed significantly. Overall, these results indicated that the construction of large impoundment dams has been associated with some changes in patterns of regional seismicity. The findings would guide researchers to further investigate the type of impacts that dam construction may have on seismicity patterns.

Published: November 2021

A finite element (FE) model is presented in this work that is used to analyze the effect of pitting corrosion on the CO2 corrosion behavior of oil and gas pipeline welds. The FE model contains two parts, i. e., stress calculation of the welded joint using Abaqus software, and of the chemical reaction at the welded joint using COMSOL Multiphysics® software. The effect of transportation pressure, pit depth and welding material on the CO2 corrosion behavior of weld metal was investigated using the FE model. It turned out that the FE model is helpful to instruct the management and to assess the remaining service life prediction of pipelines in the oil and gas industry.
Effects of rice husk ash on itself activity and concrete behavior at different preparation temperatures
Authors: Tian Erbu , Frank Chen Y. , Zhuang Yizhou , Zeng Wuhua
Published: November 2021

This paper aims to investigate the effects of rice husk ash (RHA) on itself activity and its concrete performance at different preparation temperatures for which three temperatures of 650 °C, 800 °C, and 900 °C were considered. To find a reasonable particle size, the effect of the particle size of the RHA on the workability of concrete at various grinding times was studied. A series of experiments were carried out to study the characteristics of the RHA, including X-ray fluorescence, XRD, ESEM, and an activity test. The carbonation resistance and frost resistance of concrete incorporating RHA were also investigated, where 10 and 30 wt.-% of cement was considered. The results show that the surface area of the RHA first increases and then decreases with grinding time. When the RHA is ground for 30 min, its surface area is largest and the workability of its mixture is also best. The burning temperature has little effect on the amount of SiO2. Although the structure and activity of SiO2 in RHA change at different burning temperatures, the performance of concrete incorporating RHA is higher than that of control concrete without RHA. With the same content of RHA, both carbonization resistance and frost resistance decrease with an increasing burning temperature of RHA. At the same burning temperature, both carbonization resistance and frost resistance increase with an increasing amount of RHA. Among all types of mixtures, the mixture incorporating 30 % RHA burned at 650 °C (i. e., RHA650) yields the best performance.
Investigation of Cu whisker growth by molecular beam epitaxy
Authors: Elibol Cagatay , Strunk Horst Paul
Published: November 2021

There is a trend towards smaller and smaller structures (nanostructures/ miniaturization) which is well-known in microelectronic, energy and semiconductor applications. Nanoengineering is expected to lead to significant improvements in the intrinsic properties of structures, e. g., in energy storage for supercapacitors. In this context, a deeper understanding of the growth mechanisms of the thinnest crystal layers is of crucial importance for the controlled growing of nanowhiskers with outstanding properties. In the present study, we consider a simple whisker growth model based on the surface energy (i. e., wettability) of the components and investigate the effect of the carbon interlayer deposited on a Si (111) wafer using the magnetron sputtering technique on the whisker formation during the subsequent molecular beam epitaxy process in the Si-C-Cu system. In the present study, the topographic holes in the carbon layer which are the preferred nucleation areas of whiskers were identified by a series of scanning tunneling microscopy analyses, and the natural hole density was statistically determined. Using atomic force microscopy, the surface roughness of the carbon layer was characterized. The results of our investigations indicate that there is a correlation between the hole density in the carbon layer and the density of Cu nanowhiskers. This may validate the supposition that the holes in the carbon layer are the preferred nucleation sites for whiskers – an effect that could be relevant for future works on the growth of nanowhiskers at predefined positions.
Age-selective harvesting in a delayed predator–prey model with fear effect
Authors: Mondal Ashok , Pal Amit K.
Published: November 2021

In this article, we discussed the dynamic behavior of a delay-induced harvested predator–prey model with fear effects (perceived by the prey). We then considered selective harvesting terms for both species which provide some fixed elapsed time to the prey and for the predator population before they are harvested. In other words, we are limiting the harvesting of species below a certain age so that they can grow to a certain specific size or age and thus protect juvenile populations. Reproduction of the prey population can also be greatly impeded due to the influence of the fear effect. The consideration of selective harvesting together with the effect of fear on the proposed system to show stable coexistence to the oscillatory mode and vice versa via Hopf-bifurcation. For better ecological management of the community, our study reveals the fact that collection delays and intensities should be maintained. Numerical simulations were performed to validate our analytical results.

Published: November 2021

This paper presents the validation process for the structural layer coefficient determined mechanistically for high polymer (HP) asphalt mixtures (i.e., 0.54) through full-scale laboratory testing of asphalt pavements. Two instrumented full-scale pavement experiments were conducted in the PaveBox setup at the University of Nevada, Reno. A flexible pavement structure with a conventional polymer-modified asphalt layer was evaluated in Experiment No. 1. Meanwhile, a flexible pavement structure with a reduced-thickness HP asphalt concrete (AC) layer was evaluated in Experiment No. 2. Similar vertical surface deflections (except under the center of the applied surface load), higher vertical stresses at the middle of the base layer, and similar vertical stresses below the subgrade surface were observed with the reduced thickness of the HP AC layer. Moreover, better overall fatigue and rutting performance in the AC layer, slightly higher rut depths in the unbound layers, and similar total rut depths were observed by means of mechanistic analysis with the use of HP AC pavement. In general, the results and findings of this study supported the selection of 0.54.
Study of Flash Flood in the Rishiganga and Dhauliganga Catchment in Chamoli District of Uttarakhand, India
Authors: Rawat M.S. , Dobhal R.
Published: November 2021

The present study is an attempt to investigate a flash flood that occurred on the morning of 7th February 2021 in the Rishiganga and Dhauliganga Catchments in Chamoli District of Uttarakhand. A catastrophic flood was triggered due to a massive rock-cum-snow avalanche caused by Antecedent Snow falls in the region. A huge flash flood was generated as a tremendous quantity of rockslide, comprising deposited ice and snowmelt, rolled down the Ronthi Glacier and flowed downstream into the glacier valley. This massive flash flood hit the NTPC's Tapovan-Vishnugad hydel project and the Rishiganga Hydel Project, bridges, roads, and communities in and around Raini, Tapovan and Joshimath regions in the Chamoli district of Uttarakhand. The mud and slush-inducing elements resulted in the development of a dammed lake, which momentarily blocked one of the Rishiganga's tributaries. Temporal satellite image has been used to access the information of disaster damage assessment in the region. The high-resolution satellite image clearly showing flash flood watermarks in the region and on the avalanches site rock outcrops reaching up to 50–130m height on the way to Raini Gaon. As part of our analysis, we have also looked at the valley's slope profile, which clearly shows the valley's height following the destruction. It is estimated that more than Rs 4,000 crore infrastructures loss due to this flash flood in the region. Besides, two bridges have also been lost. Hydometeriological analysis was also carried out in order to obtain the trend of rapid increase in temperature in the valley where disaster occurred. Using remote sensing (RS) and Geographic Information System (GIS) techniques, thematic layers were generated for obtaining information on the flash flood.

Published: November 2021

Cardiac lipoma is extremely rare. Here, we present a unique illustrative case of an interatrial septal lipoma protruding into the right atrium, causing symptoms in a 54-year-old male. Echocardiogram and computed tomography showed a well-shaped, giant, and fixed mass located in the interatrial septum and right atrium. The only manifestation was palpitation, though the mass filled almost all of the atrium and compressed the superior vena cava. The patient received resection of the large-sized lipoma, which was 87mm in diameter and weighed 300-400g. Pathological exam demonstrated mature lipocytes and substantiated the diagnosis of lipoma. The patient did well postoperatively, and symptoms were resolved.

Although minimally invasive direct coronary artery bypass (MIDCAB) is a less invasive procedure, internal thoracic artery (ITA) harvesting is difficult. A 65-year-old woman was advised to undergo MIDCAB for recurrent in-stent restenosis. We harvested the ITA using three-dimensional endoscopy without robotics and determined the scope position using enhanced computed tomography. We changed the camera installation between the wound and the camera port, according to the harvesting site with a harmonic scalpel using the skeletonized technique. We harvested the ITA from the subclavian vein level superiorly to the xyphoid process level inferiorly.
Synthesis and mechanical behavior of composite material reinforced with Guadua fiber and with a polyurethane or polyester matrix
Authors: Acosta Ricardo , Calle Trujillo Gabriel , Marulanda Arévalo José Luddey
Published: November 2021

A reactive hot-melt resin (polyurethane) was used to manufacture Guadua composites with a certain flexibility, high processing speed, good initial rigidity, and high temperature performance. These composites can support a moderate tensile stress, allow for large strains at low stresses, and have a low density and a working temperature range of -40 °C and 110 °C. During the flexural test, bamboo composites with reactive polyurethane matrix do not break or fail during the test. A polyurethane-based reactive hot-melt resin was characterized by tensile tests, Shore hardness tests, differential scanning calorimetry, and thermogravimetry. Besides, a composite material was made with Guadua fiber and polyester matrix, which had a greater strength in the test of tension and flexion, although it had a lower percentage of elongation than the composite material with reactive polyurethane. Guadua fiber can increase the strength by 266% of polyurethane matrix and 228% of polyester matrix.

Authors: Matygulina Venera , Chistova Natalya , Vititnev Aleksandr , Chistov Roman
Published: November 2021

This paper presents the results of research on the treatment of secondary wood fibre semi-finished materials using a dry-grinding-type rotary cutting mill and the possibility of their use in finished products for various purposes. The physical phenomena, processes, and regularities of the treatment of secondary wood fibre materials in dry processing conditions were determined and evaluated. The influence of grinding plant design parameters on wood fibre quality indices was evaluated. Mechanical effects on wood fibre waste of face-cross cutting (cutting, crumpling, collapsing, and breaking) and the dry grinding environment (breaking, collision, defibering, and fibrillation) was studied. These phenomena contribute to the formation of external and internal fibrillation of secondary wood fibre and an increase in the specific surface area. This is achieved in the absence of high temperatures and pressure, in the absence of chemical additives, and without the application of water and vapour. The effectiveness of secondary wood fibre semi-finished material treatment was demonstrated under dry processing conditions, thus confirming the environmental and economic feasibility of this method.

Published: November 2021

In this research, it was tried to choose a kind of perovskite catalyst with optimized formulation La0.8Sr0.2Co0.66Fe0.34O3 to remove air pollutants. This perovskite catalyst stabilized on the various supports such as alumina and ZSM-5 with the sol-gel synthesis technique and ceramic monolith by dip-coating method. Four different catalysts by variable weight percentage including PE-Al 10%, PE-Al 20%, PE-Al 30%, and PE-Al 40% were prepared by sol-gel synthesis technique. In this work, the XRD technique was used to confirm the formation of perovskite catalysts’ crystalline phases on the supports. As a result, XRD patterns revealed the formation of the perovskite phase onto the alumina and zeolite supports. Activity tests of these four catalysts were examined in the catalytic oxidation of Toluene and CO using an experimental setup consisting of a tubular flow reactor at the temperature 280-400°C and 100-400°C for the toluene and CO removal systems, respectively. According to the results of the catalysts’ activity test, the alumina supported with 40% w/w perovskite catalyst showed the best performance, and its activity was similar to the activity of the bulk catalyst (over 95% conversion of toluene at about 290°C). For the coated catalysts on a ceramic monolith, the complete removal of carbon monoxide at 50°C was lower than the powdered form. Results from the activity test in a toluene removal system that show coating of the bulk and supported catalysts on ceramic monolith; have an essential impact on the activity test of these catalysts.

Procurou-se, de certa forma, estabelecer uma ponte entre a atividade do tradutor e do didata das línguas quando este participa na definição do currículo, na tradução do conhecimento científico para a seleção dos conteúdos e das metodologias para o ensino de uma língua, recorrendo ao conceito de transposição didática. Poderemos verificar que a transposição do saber cientifico-acadêmico para um saber pedagógico não está isenta de problemas, podendo, por isso, associar-se-lhe a máxima traduttore, traditore, muitas vezes aplicada à tradução. Não obstante, a equacionar-se a possibilidade de traditore, o mesmo sucede por se adequar, em sala de aula, os conteúdos a ensinar às características dos discentes e não por infidelidades aos conteúdos e às competências dos programas curriculares.

Published: November 2021

Introducción: Durante los primeros seis meses de la pandemia por COVID 2019 se han publicado varios estudios que describen diferentes manifestaciones neurológicas en pacientes con COVID-19.
Objetivo. Recopilar y sintetizar evidencia científica publicada dentro de los primeros seis meses después de la declaración de la pandemia por COVID-19 sobre manifestaciones neurológicas en pacientes infectados con el SARS-CoV-2, así como su sus variaciones y frecuencia en poblaciones específicas.
Materiales y métodos. Se realizó una búsqueda de la literatura en PubMed/MEDLINE mediante la siguiente estrategia de búsqueda: tipo de estudios: cualquier estudio que describiera manifestaciones neurológicas en pacientes con COVID-19; periodo de publicación: marzo 11-agosto 31, 2020; idioma de publicación: inglés; términos y ecuación de búsqueda: (("COVID-19") AND "Neurologic Manifestations").
Resultados. La búsqueda inicial arrojó 388 registros, de los cuales 79 cumplieron los criterios de elegibilidad y fueron incluidos para análisis completo. La mayoría de estudios fueron reportes de caso individuales (50.63%) y series de casos (18.99%), y solo 30.38% fueron estudios analíticos, siendo los estudios transversales los más frecuentes (n=25). La manifestación neurológica más comúnmente descrita fue la alteración de olfato y/o gusto (43.04% de los estudios), seguida de neuropatías (20.25%), convulsiones (8.86%), encefalitis (7.59%) y delirium (5,06%). Otras manifestaciones reportadas en menor proporción fueron cefalea, miositis, accidente cerebrovascular (ACV) y mielitis.
Conclusión. La mayoría de las manifestaciones neurológicas reportadas tienen una evolución favorable, ocurren en pacientes jóvenes sin comorbilidades y no tienen relación con la gravedad de la COVID-19. Otras manifestaciones como delirium y crisis epilépticas se presentan de forma más frecuente en población con antecedente de demencia o epilepsia. Finalmente, algunas manifestaciones como el Síndrome de Guillain-Barré y el ACV pueden causar secuelas.
Retos en la educación de posgrado en medicina en tiempos de pandemia de la COVID-19

Published: November 2021

La educación de posgrado en medicina afrontó varios desafíos durante la pandemia por COVID-19 producto de la necesidad de poner en marcha un sistema educativo a distancia (online). Por ejemplo, capacitar al personal docente en el uso de herramientas y plataformas virtuales de enseñanza o incluir en dichas plataformas suficiente contenido para garantizar que los estudiantes tengan un aprendizaje apropiado. Si bien estos problemas se han sorteado exitosamente durante la pandemia en Perú, consideramos que existen otras dificultades que también deben ser abordardas.
The effect of anxiety on foreign language academic achievement
Authors: Andrea Tóth
Published: November 2021

Anxiety has commonly been regarded as one of the most significant affective obstacles in language learning achievement, and has been the subject matter of many second language researches (MacIntyre & Gregersen, 2012; Huang, 2012; Hewitt & Stefenson, 2011; Riasati, 2011; Horwitz, 2001).

The primary purpose of the present study is to explore the anxiety levels of a class of students studying at the University of Dunaújváros and to investigate their attitude towards acquiring a second/foreign language. On the basis of the information gained the study is aiming at revealing some degree of correlation between students’ anxiety and their academic achievement.

Responses to the Foreign Language Anxiety Scale show that the relatively high levels of anxiety among these participants are related to the worry about (1) the consequences of failing their foreign language class, (2) thinking that the others are better at languages and (3) communication with native speakers of the foreign language. However, the results on the relationship between anxiety levels and academic achievements show no significant correlation between these two variables, which leads us to the conclusion that the participants’ anxiety levels do not exceed the level which would have a negative impact on their academic results.
The role of social factors in the successful ageing – Systematic review
Authors: Takács J. , Nyakas C.
Published: November 2021

Purpose

Ageing is a complex phenomenon that should be studied in a multidisciplinary approach examining the biological, psychological, and social determinants in it. There is a lack of understanding of how social factors contribute to a better and healthier way of ageing. Based on previous studies social factors have a more essential role in ageing successfully. These factors have a significant influence on mental and physical health as well. The present review aims to collect the most researched social factors related to successful ageing and to examine the associations revealed between social factors and successful ageing.

Materials/Methods

We conducted a systematic review by the guidelines of the PRISMA statements. We examined the studies included by using a qualitative synthesis to identify the most important social factors and their role in successful ageing.

Results

In total, 18 original articles published in English between 2015 and 2020 were included in the review. The examined social factors related to successful ageing can be classified into four categories: Social engagement/participation, Social support, Social integration/network, and Socio-demographic/Socioeconomic factors. Social factors are modifiable and protective determinants, they could eliminate the negative effects of psychological factors while modifying the effects of physical determinants of ageing at the same time.

Conclusions

Our results have implications for future studies, as successful ageing should be examined in a multidimensional way. They should provide further evidence for the mediating/moderating importance of social factors which also have relevance in practice. Social factors could provide a quality life for years to come.
Case of parvovirus B19 infection and immunodeficiency in the patient with Gilbert syndrome

Published: November 2021

A case of long-term persistence of parvovirus B19 is described for the first time in a patient with Gilbert's syndrome against the background of immunodeficiency with predominance of infectious symptoms (chronic herpesvirus infection). Previously, the patient (male, 48 years old) was diagnosed with Gilbert's syndrome, chronic rhinosinusopharyngitis, and chronic herpesvirus infection. In July 2017, parvovirus B19 DNA was detected in blood. No clinical manifestations of infectious erythema were noted. The patient was admitted to the medical center of St. Petersburg Pasteur Institute. His blood samples obtained under informed consent were examined at the medical center in Central Clinical and Diagnostic Laboratory of St. Petersburg Pasteur Institute in January and June 2018 and in November 2019. ELISA test systems “Anti-Parvovirus B19 ELISA (IgM)” and “Anti-Parvovirus B19 ELISA (IgG)” (Euroimmune, Germany), as well PCR reagent kit “AmpliSens Parvovirus B19-FL” (FSB Central Research Institute of Epidemiology of Rospotrebnadzor, Russia) were used for specific diagnostics. Interferon status was determined by the induced production of IFN types I, II and circulating (serum) interferons. Moreover, we considered the laboratory data obtained earlier at different medical facilities of St. Petersburg. IgM class antibodies to the parvovirus B19 were not detected in the blood samples obtained in 2018. IgG antibody titer was 96 IU/ml and 264 IU /ml, respectively. Parvovirus B19 DNA was isolated from blood plasma, but the viral load was less than 720 IU of PVB19 DNA/ml (1.5 x 102 and 1.9 x 102 copies of DNA/ml, respectively). Clinical blood analysis, showed only minor (no more than 7%) deviations from the reference values, increased hemoglobin saturation of red blood cells (RBC), a decreased width of RBC distribution curve, and relative lymphocytosis. A deficiency of various interferon types was revealed: IFNγ level was 80 IU/ml in both samples, IFNα, IFNβ amounts varied from 80 to 160 IU/ml, respectively. The period of parvovirus B19 DNA persistence in blood was 11 months in presence of immunodeficiency. The patient was administered drugs of the interferon group. Parvovirus B19 DNA was not detected in clinical samples of November 2019; IFNα, IFNβ and IFNγ values were 160 IU/ml. We have detected recovery of lymphoid cell ratio, increase in their number, and improved indexes of interferon status.
