Background: COVID-19 is spreading rapidly and potentially affects every person, including fracture patients. This study was conducted with the aim to evaluate our primary months’ experience of surgical treatment of fractures in COVID-19 infected patients in order to assist in better decision-making in the next waves of the infection.
Methods: In this cross-sectional study, 15 patients with orthopedic trauma and COVID-19 infection were included from 2 trauma centers during February and March 2020
Results: Most of the patients were younger than 40 year of age. The most common COVID-19 related symptom at presentation was malaise, and a hypoxia rate of 85.7% was detected among the patients. Two-thirds of the fractures were in the lower extremities. One patient expired, but all others were discharged with no follow-up complications.
Conclusion: Surgical management of fractures in COVID-19 patients is inevitable. To achieve this, sensitive screening techniques and standard protection measures are essential.

Does Spine Surgery in Patients with a History of Bariatric Gastrectomy Increase the Risk of Delayed Pulmonary Embolism?
Authors: Zarei Mohammad , Rostami Mohsen , Yaseen Khan Furqan Mohammed
Published: March 2022

Background: This is a novel observation report on patients undergoing spine surgery with a history of bariatric procedures. Acknowledgment of aggregated complications in such patients can prevent catastrophic outcomes.
Case Report: We report three patients with spinal disorders and a history of bariatric surgery who developed pulmonary embolism following spine surgery. None of the patients had a history of venous thromboembolism or deep vein thrombosis (DVT) before this event. All patients were given thromboprophylaxis after both bariatric and spine surgery, including intra- and post-operative mechanical and pharmacological thromboprophylaxis upon discharge.
Conclusion: Patients undergoing spine surgery with a history of bariatric procedures are at increased risk of developing venous thromboembolic complications, including pulmonary embolism. We recommend extensive venous thromboembolic evaluation and treating these patients as high-risk individuals even in the absence of active thromboembolic disease.

Background: Osteochondroma is the most common benign tumor of the bone.
Case Report: In this case, we present a young patient complaining of sensation of a mass in her abdomen since a few weeks ago and abdominal pain, which caused her visit to the clinic. Imaging studies revealed a well-defined lobulated lesion, and pathological examination was correlated with osteochondroma of the iliac bone
Conclusion: This site for osteochondroma is very rare, and this case was the solitary type.
Carpal Tunnel Syndrome Secondary to the Lipoma Mass: A Case Report and Review of Literature
Authors: Talebi Shahin , Sheibani Shirin , Teimourey Alireza , Dehghan Mojtaba
Published: March 2022

Background: Lipomas are benign adipocyte proliferations and the most common tumors in soft tissue, although the appearance of this tumor in the hand is rare. The most common peripheral compressive neuropathy is carpal tunnel syndrome (CTS). CTS caused by a space-occupying lesion such as lipomas is rare and causes more complications than idiopathic CTS.
Case Report: This report was about a case of a 62-year-old woman with a giant painless mass on the first web of her right hand, with no systemic symptom and just a burning sensation in her fingers. After evaluations, CTS was diagnosed. Surgical dissection of the mass was performed, and the patient’s symptoms improved. The pathology report indicated that the mass was a lipoma.
Conclusion: It is essential to examine the presence of different masses when the patient has neurological symptoms without justifying the history.
Revisiting Angular Momentum Quantization in Bohr's Atomic Model
Authors: Sales Jorge Henrique de Oliveira , Suzuki Alfredo Takashi
Published: March 2022

One of the most important developments of modern science was the emergence of the concept of energy quantization which forced its way into our previous classical understanding of matter in nature. Modern day view of matter constituents and present understanding of atomic structure basic to quantum chemistry arose in those first decades of last century. In this line, a key feature for the understanding of microscopic atomic structures and their stability was the concept of angular momentum quantization. To capture the beauty and the power of these concepts is therefore extremely relevant for apprehending the contemporary view of matter, energy and interactions in nature. In this work we present a possible alternative approach of quantizing the atomic orbit for the hydrogen's atom model proposed by Bohr without using his hypothesis of angular momentum quantization from the start. In our approach here we show that when we identify the number of photons and the quantum number for the orbit, we are led to Bohr's hypothesis as a consequence of the Planck's energy quantization.
The Critique of Philip Sidney and Percy Bysshe Shelley on Plato’s Views about Poetry
Authors: Eliopoulos Panos
Published: March 2022

In the platonic dialogue Ion, Socrates clarifies that poetic creation is a result of inspiration but not of knowledge. As a gift from the Muses, poetry cannot even have a didactic role; since it is not rational and does not constitute a product of right reason, it cannot satisfy the needs of the person who aspires to the acquisition of wisdom. This insistence of Plato on the potential moral deficiency of poetry proves that only epistemological criteria can assist the political balances that are required in his ideal Polis. Since poetry is mimesis and a subcategory of rhetoric, it is deduced that it stands far from the truth. For Philip Sidney, however, in his critique of Plato’s views, the poet is directly connected with “poiein”, the act of creating. As a creator, he is close to the truth, and he is an owner of the Idea, to which he urges other human beings. As such, the poet is a stronger intellectual figure than the philosopher, due to the fact that he does not abstractly think of moral values but helps to proliferate them. The poet never lies, despite what Plato claims, because the poet never confirms the knowledge of anything, quite unlike the philosopher. Shelley, on the other hand, places great emphasis on the role of imagination within the context of poetic work. He declares that poetic imagination exceeds the borders of reason, thus being rendered the only human faculty that can not only see the ideal forms that Plato is enthusiastic about but also is capable of competently expressing the “eternal truth of life”. The two English poets are in accord about poetry signifying unity and harmony, not only with the abstract truth of the world but with virtue and law as well, providing the human being with the right ontological orientation.
Raising the Quality of Life Through the Therapeutic Urban and Architectural Landscape
Authors: Crăciun Cerasella , Nicolaescu Alexandra-Mara
Published: March 2022

Resilient Planning of the Therapeutic Landscape, involves the integrated balance between natural and anthropogenic elements. Emphasis is placed on the spatial aesthetic and functionality, through the relationship between social, economic and cultural elements. Taking into account the pressures of modern society and the poor degree of adaptability to the social environment, the Therapeutic Landscape development responds to these needs, intending to improve the quality of life, of the physical and mental health. Starting from the history of the restorative gardens, the typologies of “healing” green spaces, definitions of scientific terms and ideas in the field of urban development, the Resilient Landscape and the Therapeutic Landscape, it is desired to establish some basic principles for a coherent evolution of the specific integrated spaces in the urban tissue. All of these being relevant for improving and raising the quality of community life, as well as for the urban metabolism of contemporary cities, with an effect on urban pathology and public health. The article aims to achieve a scientific approach of the impact that Therapeutic Landscape and curative green spaces have on the macro, mezzo or detail level, on the urban-territorial environment, urban pathology, community health and on life in general.
Heinrich Schoenberg: Modernist Architect in Interwar Bucharest
Authors: Popescu Valentin
Published: March 2022

Bucharest multiculturalism was a feature of its cultural life throughout the 19th and 20th centuries. It contributed to the interwar architectural development and creative output of Bucharest. This development envolved some lesser known jewish architects such as: Emanuel Arnet, Leon Silion, Jean Krakauer, Iacob Rosinthal, Harry Schoenberg. The opinions expressed by interwar architects concerning modern architecture was facing the opposition of traditionalist architects. The modernisation of Bucharest was a matter of architecture and identity. Therefore the article also makes a hypothesis concerning the anonimity of a magazine report about the modern architecture of Bucharest published in “Romanian ilustration” of 24.08.1932. This magazine report was published in the antisemitic atmosphere in interwar Bucharest. Based on some clues the article attempts to identify the authors of the report, both the interviewed architect and the journalist. The article will give a general outline concerning the life and activity of the presumed author, the architect and artist Heinrich Schoenberg. The Sionist interests of Henry Shoenberg’s siblings and family will also be discussed.
Prolegomena do problematyki wykładni międzynarodowego prawa podatkowego
Authors: Brzeziński Bogumił
Published: March 2022

Międzynarodowe prawo podatkowe jest znaczącą dziedziną prawa międzynarodowego. Specyficznym przedmiotem regulacji prawnej jest tu w głównej mierze rozdział pomiędzy suwerennymi państwami kompetencji do opodatkowania tych samych zjawisk gospodarczych, a zwłaszcza osiąganego dochodu. Nie pozostaje to bez znaczenia dla wykładni jego przepisów. Umowy w sprawie zapobiegania podwójnemu opodatkowaniu są stosowane przede wszystkim w stosunkach między państwem a jednostkami poddanymi jego jurysdykcji podatkowej. Ten fakt determinuje powszechność stosowania przepisów tych umów. Konsekwencją tego stanu rzeczy jest potrzeba pogłębionej refleksji nad ich treścią, odtwarzaną w procesie interpretacji tych aktów prawnych, a w konsekwencji także nad zasadami wykładni przepisów międzynarodowego prawa podatkowego. Artykuł przedstawia najbardziej ogólne uwarunkowania społeczne i polityczne, w jakich tworzone jest i funkcjonuje międzynarodowe prawo podatkowe.
Społeczne ujęcie sportu. (Trudne) definiowanie zjawiska i jego dyskurs
Authors: Nosal Przemysław
Published: March 2022

Jednym z kluczowych aspektów społecznego fenomenu sportu pozostaje paradygmatyczność dyskursu z nim związanego. Kategorie w nim używane stosuje się bowiem często do opisu również innych sfer życia społecznego. Sport dostarcza reguł rywalizacji, proponuje określone sposoby poznawczego porządkowania świata (rankingi, rekordy, pomiary), podkreśla centralność ciała w rzeczywistości społecznej czy kładzie nacisk na społeczną potrzebę transgresji. Pomimo takiego dyskursywnego usytuowania pozostaje on zjawiskiem trudnym do zdefiniowania przez nauki społeczne. Celem niniejszego tekstu jest więc próba wypracowania definicji sportu, która uwzględniałaby specyfikę fenomenu i zarazem dostarczałaby narzędzi do teoretycznej i empirycznej refleksji nad sportem. Składa się on ze wstępu i trzech części merytorycznych. W części pierwszej zarysowana została społeczna specyfika sportu, która wiąże się z procesem jego definiowania. Następnie – w drugiej części – przedstawiono dwa skrajne podejścia do wytyczania ram zjawiska: atrybucyjne i kontekstualne. W ostatnim fragmencie zaprezentowane zaś zostało ujęcie, które można określić mianem ustrukturyzowanego kontekstualizmu, czyli definiowania sportu jako zespołu praktyk społecznych, które zbiorowości określają mianem sportu, ale które również mają pewną utrwaloną i uniwersalną strukturę, rozumianą w danej zbiorowości jako grupa fundamentalnych cech wspólnych i koniecznych, by analizowaną praktykę określać mianem sportu.
Sport osób niepełnosprawnych w przekazie i dyskursie medialnym w Polsce
Authors: Niedbalski Jakub
Published: March 2022

Celem artykułu jest analiza dyskursu medialnego dotyczącego sportowców niepełnosprawnych. W artykule skupiam się z jednej strony na sposobie, w jaki sportowcy niepełnosprawni i sport paraolimpijski funkcjonują w ogólnopolskich oraz lokalnych mediach, z drugiej zaś staram się rozwikłać przyczyny oraz skutki określonych przekazów medialnych. Jest to zatem próba określenia wpływu, jaki polskie media mają na postrzeganie sportu niepełnosprawnych przez pozostałych (przede wszystkim zdrowych) członków naszego społeczeństwa. Przyjrzę się zarówno ogólnej charakterystyce dyskursu istniejącego wokół sportu niepełnosprawnych, ale także odwołam się do opinii samych sporowców oraz innych osób ze środowiska sportowego, rekonstruując na tej podstawie to, w jaki sposób postrzegają oni istniejącą „sytuację medialną” i jak według nich wpływa ona na ich codzienne życie. Jest to próba skonfrontowania wizerunku medialnego sporowca niepełnosprawnego z opiniami i odczuciami samych sportowców.
Body art – ciało, sztuka, technologia. Od ciała ułomnego do bezawaryjnego humanoida
Authors: Franckiewicz-Olczak Izabela
Published: March 2022

Dyskurs artystyczny, analizując kondycję ciała i jego status w stechnicyzowanym świecie postbiologicznym, w którym nie należy już ono do porządku natury, w dużym stopniu pokrywa się z dyskursem naukowym pod względem przedmiotu badań, a często również wniosków z nich płynących. Obie perspektywy różnią się jednak pod względem metody. Prezentowany artykuł zestawia z tematyką wybranych prac artystycznych główne problemy współczesnej humanistyki, takie jak: sprzeciw wobec starzeniu się ludzkiego ciała, ingerencja w ludzką cielesność, transplantologia, genetyka czy ekshibicjonizm.
Ciała osobliwe w przestrzeni "freak/talk show"
Authors: Brzozowska-Brywczyńska Maja
Published: March 2022

Odmienność cielesna jest podstawą doświadczania obcości drugiego człowieka. Konfrontacje z ciałami osobliwymi w przestrzeni publicznej pozostawiają nas często bezradnymi, a jednocześnie wymagają wypracowania strategii radzenia sobie z ich obcością. W nowoczesności wykreślone zostały dwie główne ramy dla heterotopicznej cielesności: medykalizacja i normalizacja. Mogłoby się więc zdawać, że w miejscu dotychczasowej przestrzeni pokazów osobliwości zieje pustka. Ślady spektakularnej logiki freak shows da się jednak wytropić w telewizyjnym formacie talk show. Ich zestawienie w tekście nie ma na celu jedynie skonstatowania powierzchownych analogii, ale też wskazanie na głębsze podobieństwa w odniesieniu do reprezentacji cielesnej odmienności oraz poszukiwanie metanarracji usprawiedliwiającej jej obsceniczność. Artykuł zamyka pytanie o możliwość wykorzystania ambiwalencji pokazów osobliwości (jak w performansach niepełnosprawnych artystów) do uobecniania ciał osobliwych w przestrzeni publicznej.

Published: March 2022

Self-assessment is to engage students as active participants in their learning and to reflect the results of their efforts since the key idea of self-assessment is that a child should achieve the learning goal and realize his achievements. The purpose of the study is to reveal the factors causing the lack of self-assessment in primary school lessons. The research collected data using observations and a questionnaire. The participants included 60 primary school teachers from the school of Almaty, the Republic of Kazakhstan. The collected data were analyzed using percentages. Based on the results of the research, the lack of the self-assessment component in the educational process is caused by the lack of assessment tools, which explains the negative attitude of teachers toward self-assessment. The efficiency of the implementation of the innovation in inclusive education needs to ensure the proper training of teachers, including key competencies for working in inclusive classes, and strengthening of its practical component.

La vanguardia de los Contemporáneos, una estética de la dilación
Authors:   Universidad de Sevilla, Spain, Davis González Ana
Published: March 2022

This paper seeks to dialogue with the preceding critic about the possible classification of Contemporáneos texts as avant-garde. Our proposal is that some of their poems can be classified as avant-garde if we understand the avant-garde as a 20th century art paradigm and not only as a historical category during the beginning of the century. For this purpose, in the first place, the dichotomy “threshold aesthetics / dilation aesthetics” is proposed to explain two avant-garde poetic modalities, starting from the expression “threshold aesthetics,” coined by Luciana Del Gizzo (2017). Secondly, the “aesthetics of dilation” is applied in the poetic Contemporáneos texts in contrast to the threshold aesthetics of stridentism or muralism, in the Mexican context.

Ethical issues of xenotransplantation in the aspect of religious views
Authors: Sharifova R. A. , Al Breizat A. Kh. S. , Kaabak M. M. , Maslikova U. V. , Yaremin B. I.
Published: March 2022

Transplantation allows us to confidently save the lives of previously doomed patients. Unfortunately, this colossal achievement of human progress has a problematic side – the shortage of donor organs. The use of animal organs could solve it. Currently, the issues of xenotransplantation have become relevant again after the experimental xenotransplantation of the kidney of a genetically modified pig in 2021, and the xenotransplantation of the heart in 2022. This practice raises a number of ethical questions. Is it ethical to put humanity at risk by saving one person? Is it ethical to limit the civil rights of a xeno-recipient? Will xenotransplantation create another reason for discrimination? Can the creation of xenochimeras be considered an unacceptable interference in the Divine plan from a religious point of view? Is it ethical to use higher animals for xenotransplantation? Will an increase in the number of xenotransplants create a risk of the identity of the human race? Will xenotransplantation create new questions about equitable organ allocation? The sources of scholars of theologians related to the main Abrahamic religions on this topic are analyzed. Consideration of theological approaches to the new ethical problems presented by xenotransplantation does not allow us to find a unanimity of opinion. However, as this new branch of medical science makes concrete clinical progress, the attitude of society, religious leaders and ordinary believers towards it will improve. From an individual point of view, Judaism does not object to xenotransplantation to prolong and save human life, even in the case of non-kosher animals with genetic modifications. The preservation of life outweighs other values almost without exception. Xenotransplantation, even from a pig, is hailed as a life-sustaining medical intervention from a Jewish ethical perspective by most authors. In Christianity, the motivation is to try to follow the example of Jesus Christ in bringing healing to all those in need. While physiological healing is important, the ultimate goal is the overall well-being of the individual, which requires spiritual, mental, and social well-being in addition to physical health. The most correct generalization about Islamic bioethical views on xenotransplantation would be that, given the state of science, the final ethical and legal definition remains ambiguous, but in general, xenotransplantation as a means of saving human life may be acceptable.

The Russian Federation belongs to the countries with very high cardiovascular risk. Data on risk factors for death in people of old age and long-livers are not well understood. Objective. To summarize the experience of organizing treatment and inpatient rehabilitation of elderly patients and long-livers with cardiovascular diseases, to assess their cardiovascular risk factors. Methods. The study involved 50 patients, aged from 77 to 97 years (average age – 86.6 ± 4.9 years), who underwent treatment and rehabilitation for cardiovascular diseases. 32 (64 %) people corresponded to old age, and 18 (36 %) people over the age of 90 years were long-livers. There were 36 (72 %) women and 14 (28 %) men. Results. All 50 patients had arterial hypertension. Angina pectoris was diagnosed in 49 (98 %) patients. One myocardial infarction was suffered by 4 (8 %) people, two – 3 (6 %). 7 (14 %) people had a stroke, and another (2 %) suffered from the disease twice. Atrial fibrillation was diagnosed in 8 (16 %) patients, diabetes mellitus – in 11 (22 %). Сarotid arteries stenoses were found in 23 (95.8 %) patients, in 5 of them up to 50–55 %, including one occlusion. All patients were discharged with improvement after complex therapy in accordance with guidelines. Conclusions. A system for the rehabilitation of elderly patients and long-livers with cardiovascular diseases has been developed. Patients of older age groups have very high cardiovascular risk and prevalence of cardiovascular risk factors. Relatively small increases in blood pressure, the degree of arterial stenosis of a less hemodynamically significant level, and the use of combined therapy for cardiovascular diseases are factors that make it possible to survive until the age of long-livers.

El deterioro de la calidad del agua en los ecosistemas acuáticos constituye un problema en todo el mundo, de manera que los recursos hídricos de buena calidad podrían volverse escasos en el futuro. En la cuenca del río Margaritas diversas actividades antrópicas como la agricultura y la ganadería pueden influir en la calidad del agua y las riberas. Esta investigación tuvo como objetivo evaluar la calidad del agua y las riberas en esta cuenca del sureste de México. Se emplearon el Índice de Calidad de las Riberas (RQI, por sus siglas en inglés) y el Índice del Grupo de Trabajo de Monitoreo Biológico (BMWP) adaptado para Costa Rica (BMWP_CR). Se determinaron parámetros físicos y químicos (pH, oxígeno disuelto, temperatura y conductividad) e hidrológicos (velocidad de la corriente y el caudal) del agua y se recolectaron macroinvertebrados acuáticos en temporadas de secas y lluvias. La calidad ribereña varió de “mala” a “muy buena”. Los atributos del RQI más deteriorados fueron la regeneración natural y la composición y estructura de la vegetación ribereña. El índice BMWP_CR mostró que la calidad del agua disminuyó en la temporada de lluvias. Se contabilizó un total de 17 676 macroinvertebrados (10 954 en la temporada de secas y 6 722 en lluvias) pertenecientes a 13 órdenes y 50 familias. La familia con mayor cantidad de individuos fue Baetidae, seguida de Hydropsychidae y Elmidae. La riqueza y la diversidad biológica (H’) fueron mayores en secas. Este trabajo es el primero en integrar la calidad del agua, la calidad de las riberas y la diversidad de macroinvertebrados a escala local y regional, lo que representa la línea de base en la gestión futura del agua en la zona y para la creación de un índice BMWP adaptado a esta región del sureste de México.
Challenges with Regard to Unmanned Aerial Systems (UASs) Measurement of River Surface Velocity Using Doppler Radar
Authors: Bandini Filippo , Frías Monica Coppo , Liu Jun , Simkus Kasparas , Karagkiolidou Sofia , Bauer-Gottwein Peter
Published: March 2022

Surface velocity is traditionally measured with in situ techniques such as velocity probes (in shallow rivers) or Acoustic Doppler Current Profilers (in deeper water). In the last years, researchers have developed remote sensing techniques, both optical (e.g., image-based velocimetry techniques) and microwave (e.g., Doppler radar). These techniques can be deployed from Unmanned Aerial Systems (UAS), which ensure fast and low-cost surveys also in remotely-accessible locations. We compare the results obtained with a UAS-borne Doppler radar and UAS-borne Particle Image Velocimetry (PIV) in different rivers, which presented different hydraulic–morphological conditions (width, slope, surface roughness and sediment material). The Doppler radar was a commercial 24 GHz instrument, developed for static deployment, adapted for UAS integration. PIV was applied with natural seeding (e.g., foam, debris) when possible, or with artificial seeding (woodchips) in the stream where the density of natural particles was insufficient. PIV reconstructed the velocity profile with high accuracy typically in the order of a few cm s−1 and a coefficient of determination (R2) typically larger than 0.7 (in half of the cases larger than 0.85), when compared with acoustic Doppler current profiler (ADCP) or velocity probe, in all investigated rivers. However, UAS-borne Doppler radar measurements show low reliability because of UAS vibrations, large instrument sampling footprint, large required sampling time and difficult-to-interpret quality indicators suggesting that additional research is needed to measure surface velocity from UAS-borne Doppler radar.
Unnatural Cycles: Anthropogenic Disruption To Health And Planetary Functions
Authors: Gibson Gillian , Stewart Alex G.
Published: March 2022

Natural cycles underpin the very stuff of life. In this commentary we consider unnatural cycles: that is, anthropogenic activities which have a circularity, but whose nature is to have a detrimental effect on human health, exacerbating existing problems. Natural cycles have feedback loops, some of which have recently come to light, with an understanding that everything is connected in some way. In health, feedback loops are imperative in homeostatic mechanisms. However, in the unnatural cycle the feedback loops serve to reinforce (and in some cases amplify) negative problems. We offer a commentary on an unnatural cycle moving from air quality to lung function and back to air quality; we call this the lung disease unnatural cycle. We suggest where links occur, and where wider consideration of interactions between various disciplines can lead to breaking this unnatural (or vicious) cycle, changing it to a healthy cycle where individual health can be improved, along with better global scale outcomes. We suggest that many activities within this unnatural cycle occur within silos. However, the improved cycle incorporates joint activities at geological, health, and financial levels, to the mutual benefit of all, breaking the unnatural cycle, and improving health, life and financial costs.
Object Segmentation for Autonomous Driving Using IseAuto Data
Authors: Gu Junyi , Bellone Mauro , Sell Raivo , Lind Artjom
Published: March 2022

Object segmentation is still considered a challenging problem in autonomous driving, particularly in consideration of real world conditions. Following this line of research, this paper approaches the problem of object segmentation using LiDAR-camera fusion and semi-supervised learning implemented in a fully-convolutional neural network. Our method is tested on real-world data acquired using our custom vehicle iseAuto shuttle. The data include all-weather scenarios, featuring night and rainy weather. In this work, it is shown that LiDAR-camera fusion with only a few annotated scenarios and semi-supervised learning, it is possible to achieve robust performance on real-world data in a multi-class object segmentation problem. The performance of our algorithm is measured in terms of intersection over union, precision, recall and area-under-the-curve average precision. Our network achieves 82% IoU in vehicle detection in day fair scenarios and 64% IoU in vehicle segmentation in night rain scenarios.

The Internet of Things (IoT) is one of the most widely used technologies today, and it has a significant effect on our lives in a variety of ways, including social, commercial, and economic aspects. In terms of automation, productivity, and comfort for consumers across a wide range of application areas, from education to smart cities, the present and future IoT technologies hold great promise for improving the overall quality of human life. However, cyber-attacks and threats greatly affect smart applications in the environment of IoT. The traditional IoT security techniques are insufficient with the recent security challenges considering the advanced booming of different kinds of attacks and threats. Utilizing artificial intelligence (AI) expertise, especially machine and deep learning solutions, is the key to delivering a dynamically enhanced and up-to-date security system for the next-generation IoT system. Throughout this article, we present a comprehensive picture on IoT security intelligence, which is built on machine and deep learning technologies that extract insights from raw data to intelligently protect IoT devices against a variety of cyber-attacks. Finally, based on our study, we highlight the associated research issues and future directions within the scope of our study. Overall, this article aspires to serve as a reference point and guide, particularly from a technical standpoint, for cybersecurity experts and researchers working in the context of IoT.

Long-acting injectable antipsychotics (LAIs) offer many benefits to patients with schizophrenia spectrum disorder (SSD). They are used with very different frequencies due to questions of eligibility or patients’ and prescribers’ attitudes towards LAI use. We assessed the prescribing rates of LAIs in a large academic psychiatric hospital with public service mandate in Switzerland and compared them with other countries and health care systems. To our knowledge this study is the first to investigate the inpatient LAI-use in Europe. Medical records of all patients diagnosed with SSD discharged from the Clinic of Adult Psychiatry of the University Hospital of Psychiatry Zurich over a 12-month period from January to December 2019 were evaluated regarding the prescribed antipsychotics at the time of discharge. The rates of use of LAIs among all patients and among patients receiving LAI eligible antipsychotic substances were assessed retrospectively. We assessed records of 885 patients with SSD. Among all cases 13.9% received an LAI. Among patients who received antipsychotic medication that was eligible for LAI use 28.3% (n=434) received an agent as LAI. These included paliperidone palmitate (69.9%), aripiprazole monohydrate (14.6%), risperidone (4.9%) and first-generation LAIs (9.8%). Compared to international frequencies of LAI administration, the prescription rate of LAIs in SSD patients was low. Further studies will evaluate patient- and prescriber-related reasons for this low rate.

The COVID-19 pandemic is the biggest public health threat facing the globe today. Multiple vaccines have been approved, however the emergence of viral variants such as the recent Omicron, raises the possibility of booster doses to achieve adequate protection. In Brazil, the CoronaVac (Sinovac) vaccine was used, however it’s important to assess the immune response to this vaccine over time. This study aimed to monitor the anti-SARS-CoV-2 antibody responses in those immunized with CoronaVac and SARS-CoV-2 infected individuals. Samples were collected between August 2020 and August 2021. Within the vaccinated cohort, some individuals had history of infection by SARS-CoV-2 prior to immunization and others not. We analyzed RBD-specific and neutralizing- antibodies. Anti-RBD antibodies were detected in both cohorts, with a peak between 45-90 days post infection or vaccination, followed by a steady decline over time. In those with previous history of COVID-19, a higher, longer, more persistent response was observed. This trend was mirrored in the neutralization assays, where infection followed by immunization resulted in higher, longer lasting responses which were conditioned on the presence of levels of RBD antibodies right before the vaccination. This supports the necessity of booster doses of CoronaVac in due course to prevent serious disease.
Respiration by the Oxidative Pentose Phosphate Pathway in Chloroplasts Responds to Atmospheric CO2 Concentration
Authors: Wieloch Thomas
Published: March 2022

Despite significant research efforts, the question of whether rising atmospheric CO2 concentrations (Ca) affect leaf respiration remains unanswered. Here, I reanalyse published hydrogen isotope abundances in starch glucose of sunflower leaves. I report that, as Ca increases from 450 to 1500 ppm, respiration by the oxidative pentose phosphate pathway in chloroplasts increases from 0 to ≈ 5% relative to net carbon assimilation. This is consistent with known regulatory properties of the pathway. Summarising recent reports of metabolic fluxes in plant leaves, a picture emerges in which mitochondrial processes are distinctly less important for overall respiration than the oxidative pentose phosphate pathways in chloroplasts and the cytosol. Regulatory properties of these pathways are consistent with observations of lower-than-expected stimulations of photosynthesis by increasing Ca. Reported advances in understanding leaf respiratory mechanisms may enable modelling and prediction of respiration effects (inter alia) on biosphere-atmosphere CO2 exchange and plant performance under climate change.

Published: March 2022

The study aims to describe linear program problem-solving skills reviewed from sequential thinking styles and genders as schools implement online learning due to the covid-19 pandemic. This research is a qualitative study that produces descriptive data. The subject of this study consisted of two male students and two female students of class XI MIPA High School MTA Surakarta. The study began by determining the study subjects using a thinking style questionnaire, followed by linear program problem-solving tests and interviews. Check the validity of the data using triangulation methods. The results show linear program problem-solving skills; 1) Sequential students of male and female concrete perform systematically and less carefully; 2) Abstract sequential male and female students collect complete data and analyze the information obtained regularly as well as female abstract sequential students strong in written decoding and symbols; 3) students' problem solving skills with sequential abstracts are higher than concrete sequential students ;4) male students with sequential thinking styles perform better at solving math problems than female students with sequential thinking styles.
Reestructuración industrial y empleo en Baja California, México (1989-2014)
Authors: Ramírez Urquidy Martín , Meza Fregoso Juan Antonio , Becerra Pérez Luis Armando
Published: March 2022

Este trabajo describe la evolución de la economía y de la industria manufacturera en el estado de Baja California. A partir de algunos planteamientos teóricos y empíricos desde la organización industrial y del análisis de los cambios en la estructura del empleo por actividad manufacturera, el trabajo encuentra tendencias de concentración del empleo manufacturero en la gran empresa y una disminución de la participación de las pequeñas y medianas empresas, lo que puede deberse a una interacción entre el nivel tecnológico característico de las industrias que siguen favoreciendo a la gran empresa, y la reducción de la dinámica económica del estado, lo cual ha promovido la concentración industrial del empleo. Por otro lado, la participación de la microempresa dentro de la industria en el largo plazo puede deberse al deterioro de la dinámica económica con respecto a los noventa del siglo pasado, lo que motivó el emprendedurismo de personas desempleadas que abrieron microempresas para mantener su fuente de ingresos.

Published: March 2022

La experiencia de innovación docente que aquí se presenta se enmarca en un sentido mayor referido a la promoción de las humanidades y el pensamiento crítico entre el alumnado universitario, atendiendo a que se trata de disciplinas que viven un periodo de amenaza constante por parte de diferentes instituciones. Así pues, con el objeto de promover la investigación en el campo humanístico por parte del alumnado, así como motivarles a continuar su carrera académica en dicho espacio, se expone aquí una acción desarrollada en el marco de una asignatura optativa de último curso del Grado en Humanidades: Estudios Interculturales (Universitat Jaume I, España). Dicha acción se centra en el desarrollo de un trabajo de investigación, que más tarde podrá ser presentado en el contexto de unas jornadas para investigadores/as noveles. De este modo, se pretende poner en valor nuestras disciplinas al tiempo que se establece en el alumnado una conciencia del valor social y académico de su trabajo.
An investigation of students’ views on decolonising the science curriculum
Authors: Williams Neil Anthony , Benjamin Audrey
Published: March 2022

Decolonising the curriculum in higher education has attracted a lot of recent attention. However, most of the work done on this topic has been within the arts and social science disciplines. By means of a questionnaire, this paper explores science students’ understanding of decolonisation of the curriculum and their views on a range of potential actions to help achieve that, based on Swartz’s theses for the process. The results indicate that, although understanding of decolonisation was low, a high proportion of students was supportive of actions linked to the agenda for decolonisation of the curriculum. Of particular note was the result that Black African/Caribbean students were more supportive of actions to decolonise the curriculum, particularly for actions focused on the content of the science being taught, than the rest of the student population. The results support the call to decolonise the science curriculum, in order to reflect the diverse student population
