Published: October 2021

This study aimed to identify the attitudes of public school teachers in the State of Kuwait at various educational stages towards the experience of distance education during the COVID-19 pandemic. The descriptive approach was applied; a questionnaire consisting of four dimensions was developed to measure teachers’ attitudes towards distance education. The study sample consisted of 1028 teachers of various disciplines at all levels of education in public schools in the State of Kuwait. The results indicated that teachers had a higher degree of positive attitudes towards the distance education experience. The results also showed that there were statistically significant differences between the study sample members due to each of the following variables: the educational district and the educational stage.The results did not show statistically significant differences due to the gender variable. Additionally, the results did not show the existence of statistically significant differences due to the variable years of experience on the total degree and dimensions of scale, except for the dimension “student assessment through distance learning using the TEAMS Program” attributed to the experience category (1–5 years).
Efficiency of coronavirus inactivation on environmental surfaces: A comparison study of two available disinfectants
Authors: Barr Kelli L. , Ronca Shannon E. , Sturdivant Rodney X. , Harris Debra D.
Published: October 2021

Background: There are many coronaviruses of significant medical and veterinary concern, all of which are the result of spillover from another species. Disinfection of healthcare and veterinary environments is an important factor in limiting the transmission of coronaviruses. Disinfection agents for coronaviruses use bleach, quaternary compounds, hydrogen peroxide, and sodium hydroxide. Product labels list contact times that range from 10-30 minutes for total inactivation. Decon7 is a combination disinfectant that is currently used in the food and agriculture, medical facilities, and other industries. While Decon7 has been shown to inactivate a variety of pathogens and disrupt biofilms, its effectiveness and rate of coronavirus inactivation has not been evaluated.Objective: This project sought to evaluate Decon7’s effectiveness and rate of coronavirus inactivation.Methods: This study evaluated the disinfection efficacy of Decon7 (diluted at 1:4) and bleach (diluted at 1:10) after 3 coronaviruses (SARS-CoV-2, HCoV OC43, and HCoV NL63) were inoculated onto up to sixteen environmental surface materials.Results: A 1:4 dilution of Decon7 inactivated all coronaviruses on all surfaces with 1 minute contact time. A 1:10 dilution of bleach was not effective in inactivating coronaviruses with a contact time of 1 minute on all surfaces.Conclusions: New technologies and chemistries may offer more efficient inactivation of pathogens on environmental surfaces. These disinfection methods and materials, which require less than 10 minutes contact time, may improve the efficacy of cleaning and disinfecting surfaces in the built environment.

In the packaging industry, disruptions occurring in the supply chain can impact all the segments and have huge consequences on the operations conducted by the distributors. We are witnesses of an unprecedented crisis caused by the COVID-19 pandemic. It has influenced all layers of the society and forced us to make changes and adjustments to our every-day routine, regulations, economy. Disruptions can undermine the stability of the supply chain, causing business losses. Therefore, identifying the impact of different disruptions on the supply chain is crucial. Here, a timely and quick reaction is of great importance. The current pandemic has caused many disruptions in the industry and has impacted all parts of the supply chains in ways that have not been yet recorded, therefore making it even harder for the companies to respond to new challenges. The changes have not skipped the packaging industry, forcing the manufacturers to rethink their strategies and the consumers to change their views of a safe and reliable product. With the economic expansion, the demand for flexible packaging and has been growing. There are many advantages to flexible packaging. Besides the fact that it creates less environmental impact, it also requires fewer resources compared to traditional packaging production. Disruptions in the supply chains of the flexible packaging industry are one of the major economic concerns during the COVID-19 pandemic, and therefore the topic of this paper. Since the companies in the industry are in desperate need for a new approach regarding risk management and building business resilience, some strategies for overcoming the challenges of the crisis on the flexible packaging market have been presented here.
Home Food Environments of Mothers in South-Eastern Africa and California-An Illustration of Global Extremes
Authors: Scudero Emma , Papathakis Peggy , Schaffner Andrew , Phelan Suzanne
Published: October 2021

INTRODUCTION: The type and availability of food in the home is known to directly shape food intake and weight status, but cross-cultural differences remain poorly documented.

OBJECTIVE: The purpose of this study was to describe and compare the home food environments of low-income, childbearing women living in a low-income country (Malawi) and a high-income country (United States). 

METHODS: A home food environment survey was available in 714 mothers in Malawi (mean BMI 19.5, mean age 22.1 years) and 371 in California (mean BMI 31.8, mean age 28.1 years).

RESULTS: Mothers in California vs. Malawi had on average (SD) 22.8 (4.4) vs. 1.2 (1.4) different food items in the home. The women in California had an abundance of fruits and vegetables that were virtually absent in the homes of Malawian women. The most prevalent food in the homes in Californian women was rice (in 97% homes) and in Malawian women was corn flour (in 47% of homes).

CONCLUSIONS: Given the global extremes in food availability, efforts to address over and under food availabilities in the homes of childbearing women need to move beyond country centric approaches. It is time to consider maternal and child health as a global priority.
Riding the Nordic German Power-Spread: The Einar Aas Experiment
Authors: Ewald Christian-Oliver , Haugom Erik , Lien Gudbrand , Song Pengcheng , Størdal Ståle
Published: October 2021

Inspired by the initial success and eventual failure of Einar Aas’ trading strategy exploiting dynamical patterns in the spread between Nordic and German electricity futures, we investigate the question whether there is evidence for possible arbitrage from engaging in both markets simultaneously and the possibility of constructing a trading strategy that ultimately beats the markets. To do this, we first assess the risk premium and relevant Sharpe values for the two markets and observe significant differences. This is followed by a discussion as to how far the different risk premia and Sharpe values alone are evidence of arbitrage. The answer is, they are not. However, we then show that an intelligently chosen long-short strategy constructed in the Einar Aas spirit can generate a positive alpha in the CAPM sense, hence providing evidence of arbitrage.

The ‘road’ of volunteering and volunteering in the context of reflections on generations Y and Z – a methodological proposal
Authors: Chojnacka Barbara
Published: October 2021

What is volunteering? What is it for a volunteer and what is its place in their life? What is or was her/his ‘road’ to volunteering, in voluntary work or as a result of volunteering? In the article, the author looks for answers to these questions, presenting a research perspective using the metaphor of the road, projection and narrative techniques. Placing them in the context of the Y and Z generations, i.e. contemporary students – volunteers. It turns out that volunteering is a very intimate, subjective experience that specifically identifies a single person – a volunteer. The presented methodological approach is a proposal for the implementation of research that allows to discover the hidden meanings of volunteering in the life of a young person.

Nonlinear Generalized Schrödinger’s Equations by Lifting Hamilton-Jacobi’s Formulation of Classical Mechanics
Authors: Gouesbet Gérard
Published: October 2021

It is well known that, by taking a limit of Schrödinger’s equation, we may recover Hamilton-Jacobi’s equation which governs one of the possible formulations of classical mechanics. Conversely, we may start from the Hamilton-Jacobi’s equation and, by using a lifting principle, we may reach a set of nonlinear generalized Schrödinger’s equations. The classical Schrödinger’s equation then occurs as the simplest equation among the set.
Hydro Power Tower (HYPOT)
Authors: Mamulashvili George
Published: October 2021

Humanity has used the power of falling water for centuries to produce electrical energy, but there have been no significant changes in technology. Marine Energy has received an explosive development. Traditional technologies are passive and have low efficiency. It is not possible to use the effect of falling water in the ocean. The chapter considers the technology, which allows to convert not only the kinetic energy of a moving horizontal flow, but also the potential energy of water hammer in a combination of pressure drop between layers of water that have different hydrodynamic characteristics. This is a high efficiency due to the use of the Pitot-Prandtl tube principle and Bernoulli’s law and in combination with the effect of raising the water of the hydraulic ram. The calculations are based on computational fluid dynamics (CFD) methods. It is known that 94% of incoming solar energy is converted into underwater currents and only 6% - on the surface. Therefore, the proposed technology can be highly competitive in relation for example to Orbital Marine Power (OMP) project and another known offshore wind and wave power plants which convert only the kinetic energy of the surface air and sea currents.
Potassium Homeostasis
Authors: S. Patil Shakuntala , M. Patil Sachin
Published: October 2021

The average potassium intake in the United States population ranges from 90 to 120 mEq/day. About 98% of the total body’s potassium is intracellular, and only 2% is present in the extracellular compartment. This distributional proportion is essential for cellular metabolic reactions and maintaining a gradient for resting membrane potential. A loss of this gradient results in hyper- or hypopolarization of the cell membrane, especially in cardiac muscles leading to life-threatening arrhythmias. Multiple mechanisms in human maintain homeostasis. Transient initial changes are due to transcellular shifts activating sodium-potassium ATPase pumps on the cell membrane. The kidneys essentially take part in excess potassium excretion, maintaining total body stores constant within normal range. Gastrointestinal secretion of potassium is insignificant in individuals with normal renal function, however plays an essential role in individuals with compromised renal function. So far, a classic feedback mechanism was thought to maintain potassium homeostasis; however, a recently recognized feedforward mechanism acting independently also helps preserve potassium homeostasis. Hence, potassium homeostasis is vital for humans to function at a normal level.
Hydropower in Russia: Case Study on Hydrological Management of the Volga-Kama Cascade
Authors: N. Terskii Pavel , S. Ermakova Galina , V. Gorelits Olga
Published: October 2021

The capacity of hydroelectric power plants (HPPs) in the Russian Federation (RF) exceeds 50 GW. It is about 20% of the total capacity of all power plants in the country. The Volga River basin is the biggest in Europe with the catchment area of 1 360 000 km2. It covers the most populated and most industrialized part of the European Russia. The largest cascade of reservoirs in Russia and Europe is the Volga-Kama cascade (VKC) constructed in 1930–1980. It consists of 12 great water reservoirs and HPPs with total capacity about 12 GW. The main peculiarity for the VKC management is the combination of different requirements by various economy sectors: safety, energy, navigation, water needs for domestic and industrial services, agriculture and fishery, recreation and ecological rules. These sectors often make conflicting demands for the VKC operation. The VKC management principle is to balance and satisfy all of them taking into account the changing climate and economical effectiveness. Modern decisions for the VKC management are based on two principles. First is the constant optimization of the whole VKC management rules, taking into account both climate change and the Strategy of the country development. The second is the constant technical modernization of the VKC equipment to achieve the best economical effectiveness and safety for ecosystems and population.
The Orange Peel: An Outstanding Source of Chemical Resources
Authors: Fontana Gianfranco
Published: October 2021

Citrus sinensis (L.) Osbeck is a very common cultivar belonging to the Rutaceae family. It is largely diffused in several areas of the world characterized by mild to warm climate conditions. Its abundant worldwide production (up to 107 Tons. per year) and consumption both as the edible part of the fruit and as several types of derivative products imply the production of a huge amount of waste, such as the fruit pomace. Several ways of recycling this material have been developed in recent years: employment as fertilizer, fodder ingredient, and even cloth material. However, the chemical added value of Citrus sinensis peel has been underestimated despite the diversified and significant content of useful chemicals, such as polyphenols, polymethoxylated phenols, glycosylated flavonoids, volatile and non-volatile terpenoids, pectins, enzymes, etc. This work aims to highlight the outstanding chemical potential of Citrus sinensis peel.

Authors: J. Kleczyk Ewa , Bana Jill , Arora Rishabh
Published: October 2021

Coronavirus disease (COVID-19) caused an overwhelming healthcare, economic, social, and psychological impact on the world during 2020 and first part of 2021. Certain populations, especially those with Substance Use Disorders (SUD), were particularly vulnerable to contract the virus and also likely to suffer from a greater psychosocial and psychological burden. COVID-19 and addiction are two conditions on the verge of a collision, potentially causing a major public health threat. There is surge of addictive behaviors (both new and relapse), including use of alcohol, nicotine, and recreational drugs. This book chapter analyzed the bi-directional relationship between COVID-19 and SUD by leveraging descriptive summaries, advanced analytics, and machine learning approaches. The data sources included healthcare claims dataset as well as state level alcohol consumption to help in investigating the bi-directional relationship between the two conditions. Results suggest that alcohol and nicotine use increased during the pandemic and that the profile of SUD patients included diagnoses and symptoms of COVID-19, depression and anxiety, as well as hypertensive conditions.

Authors: Oluwaseun Ajayi Ayodele , Peter Odeleye Olawale , Atinuke Popoola Oluwabukola
Published: October 2021

The Covid-19 pandemic is currently ravaging the globe with enormous morbidity and mortality. This pandemic, caused by the SARS-CoV-2 started from China and has spread across the globe. Initial reports indicated that the SARS-CoV-2 initially emerged among animals from where they transfer to humans. Different strategies deployed to curtail the pandemic have yielded little result. Therefore, the One-Health concept may compliment existing strategies. The One Health places emphasis on the between the animal-human-ecosystem interface and how this can be used to tackle public health problems, including the COVID-19 pandemic. One Health Surveillance will involve tracking viral pathogens in animals to access risk of transfer to humans. It will also stimulate targeted approaches for prevention and treatment of viral zoonotic infections. There should be an integrated and interdisciplinary One-Health surveillance that should incorporate veterinary, medical or public health and environmental scientists to synergise surveillance effort to track emergence of infectious diseases in the future.
Ancient and Contemporary Industries Based on Alkali and Alkali-Earth Salts and Hydroxides: The Historical and Technological Review
Authors: Wasserman Rina
Published: October 2021

Although sodium, potassium, calcium, and magnesium were isolated as the chemical elements by Sir Humphry Davy for the first time at the beginning of the 19th century, alkali salts and hydroxides have been widely known and used since the very ancient time. The word “alcali” & “alkali” was borrowed in the 14th century by literary Roman-Germanic languages from Arabic al-qalī, al-qâly ou al-qalawi (), which means “calcinated ashes” of saltwort plants. These ashes are characterized nowadays as mildly basic. They have been widely used in therapy, cosmetics, and pharmacy in Mediaeval Europe and the Middle East. However, the consumption of these alkali containing ashes, as well as natron salts and calcined lime-based materials used for different customer purposes, like therapy, pharmacy, cosmetics, glass making, textile treating, dyes, brick making, binding materials, etc., was commonly known since the very ancient times. The current review of the archeological, historical, and technological data provides the readers with the scope of the different everyday life applications of alkali and alkali-earth salts and hydroxides from ancient times till nowadays. The review obviously reveals that many modern chemical manufacturing processes using alkali and alkali-earth salts and hydroxides have a very ancient history. In contrast, there has been a similarity of targets for implementing alkali and alkali-earth salts and hydroxides in everyday life, from the ancient past till the modern period. These processes are ceramic and glass making, binding materials in construction, textile treatment, metallurgy, etc. So, this review approves the common statement: “The Past is a clue for the Future.”

Black Holes as Possible Dark Matter
Authors: Kumar Sinha Aloke
Published: October 2021

Black holes and Dark matter are two fascinating things that are known very little. They may have non gravitational interactions, but those are definitely extremely feeble in comparison to their gravitational interactions. Nowadays some people think that one may contain the other. In this chapter we will see that some black holes may contain the dark matter. These black holes decay under Hawking radiation, but do not vanish completely. They produce stable end states due to both quantum gravitational effects and thermodynamic reasons. These end states are the replicas of what we call dark matter. We will develop the complete theory for decay of such black holes, starting from some scheme independent assumptions for the quantum mechanical nature of the black holes. We will then consider explicit examples of some black holes to show that they indeed produce replicas of dark matter at their end states. Thus this chapter is going to be a manuscript for theoretical development of black hole decay from a quantum mechanical perspective and its consequences for producing replicas of dark matter.
Velocidade e Acordo

In section 49 of his Critique of Judgement, Kant uses the expression “in Schwung verstezt” in order to classify the free play of the faculties when they get involved with aesthetic ideas. “Schwung” shares the same etymological root of “swing” and suggests, literally, a shuttle-like movement for the non-stop exchange of data between the faculties. This text aims at demonstrating that an interpretation closer to the German original text throws a new light upon the nature of the cognitive play driven by aesthetic ideas. Such interpretation may help to understand, for instance, the reason why Kant uses metaphors as examples of aesthetic ideas. Etymologically, “metaphor” also means “transportation” or “to carry over”. Rather than the notion of a juxtaposition of distant semantic domains, this text wishes to employ the sheer dynamics inherent to the concept of metaphor. This dynamic character is useful in order to reinforce the plausibility of a more cinematic reading, so to speak, of Kant’s conception of aesthetic experience.
A Faculdade de Filosofia de Kant e a Ideia Alemã de Universidade
Authors: de Faria Luisa Leal ,   Philosophy Documentation Center
Published: October 2021

Kant’s small essay The Conflict of the Faculties was considered by Derrida a blueprint of the modern university, to be born a few years after its publication, through the works of Humboldt, Fichte, Schelling and Schleiermacher. According to Derrida, the concept of a Philosophical Faculty at the centre of the university, responsible for reason and truth, is now extinct. This paper tries to follow the arguments produced by the founding fathers of the modern university, and the way they were recovered at different points in time, by Nietzsche, Heidegger, Jaspers and Habermas, to show that through two centuries of change, the German Idea of the university kept in touch with the main arguments developed by Kant.
THE SANCTIONING OF INSIDER TRADING IN BRAZIL AND IN THE EUROPEAN UNION AND THE PROTECTION OF RIGHTS: A COMPARATIVE ANALYSIS
Authors: Castro Alexander De , Blachnio-Parzych Anna
Published: October 2021

Nosso objetivo aqui é comparar a proteção contra insider trading no Brasil e na União Europeia, especificamente a maneira como o insider trading é sancionado nessas duas jurisdições. Destacaremos as diferentes combinações entre sanções administrativas e criminais encontradas nos dois sistemas e suas implicações para os direitos fundamentais e da personalidade (no caso do Brasil) dos responsáveis pela prática de abuso de informação privilegiada. A possível acumulação de punições impostas por tribunais criminais e órgãos reguladores administrativos levanta a questão de saber se pode haver uma violação do princípio ne bis in idem. A resposta a essa pergunta será diferente em cada sistema. Começaremos fazendo um breve balanço da gênese e da evolução da regulamentação sobre uso de informações privilegiadas no Brasil e na UE, a fim de compreender as diferentes razões para a proibição do insider trading nas duas jurisdições de forma a entender os motivos por trás de suas divergências e convergências.

Natural history museum: A journey through time and space
Authors: Maran-Stevanović Aleksandra
Published: October 2021

The occasion of a great jubilee - 125 years since the founding of the Natural History Museum in Belgrade - merits highlighting certain historical circumstances, important events and personalities, as well as significant research and activities from the first 80 years of its existence. The fact that this paper will not be covering the modern period of the Museum is a consequence of the author's desire to have that time period reviewed and interpreted by other researchers - those who are still active witnesses. Extensive archive materials and the photo library of the Museum were used in the process of preparation, together with the reports on the work of the Museum, documents from the personal legacy of the first director Petar Pavlovic, and memoirs of antecedent museologists Petar Stevanovic and Sergei Matveyev.

Badenian sediments are found for the first time in the surroundings of the Krcedin village. They represent remnants of the Central Paratethys marginal sea. The sediments are represented by a basal conglomerate unit overlain by pure and sandy marl. Foraminifera and rare ostracods are present, limited to the marls. Normal gradation and the prevalence of planktonic foraminifera suggest a rapidly deepening basin.
The distribution of crested newts in Serbia: An overview and update
Authors: Vučić Tijana , Tomović Ljiljana , Ivanović Ana
Published: October 2021

Four, morphologically similar species of crested newts (genus Triturus) meet and hybridize in Serbia, making a complex system with several hybrid zones. The puzzling and rapidly changing taxonomic status of crested newts has been a major issue in getting hold of their distribution. We provide an overview of the current knowledge on Triturus taxonomy and compile available faunistic data into a distribution map, highlighting the species contact and hybrid zones. At the present state of faunistic and genetic research, the northwestern , northeastern , Eastern and southeastern parts of Serbia transpire as areas that are exceptionally important for the diversity of crested newts.

U ovom radu, prikazujemo ažurirane podatke o distribuciji kompleksa vrsta slepića (Anguis fragilis complex) u Srbiji. Podaci se sastoje iz nalaza objavljenih u literaturi ili na Internetu, zajedno sa prethodno neobjavljenim distribucionim podacima sakupljenim na terenu. Od dve vrste kompleksa prisutne u Srbiji, Anguis fragilis je rasprostranjen u zapadnim i južnim krajevima naše zemlje dok je Anguis colchica prisutan u severoistočnim i istočnim krajevima. U najsevernijim delovima naše zemlje konstatovano je odsustvo obe vrste, zbog nedostatka odgovarajućeg staništa. Nalazi su brojniji u planinsko-kotlinskom regionu i ređi i raštrkaniji u peripanonskom i panonskom regionu, što se delimično može objasniti nesistematskim uzorkovanjem. Lokacija i širina kontaktne zone dve vrste slepića u Srbiji je još uvek nedovoljno poznata. Pretpostavlja se da se pruža duž doline Velike Morave ka jugu a zatim prati granicu između Rodopskog i Karpatsko-Balkanskog planinskog masiva ka jugo-istoku, ali postoje indicije da se hibridna zona nalazi i zapadnije. Postoji izvesno neslaganje, u literaturi, između kontaktne zone predložene na osnovu morfoloških analiza i one predložene na osnovu molekularnih analiza. Ovo ukazuje na potrebu za opsežnijim uzorkovanjem i daljim analizama. Konačno, pošto razdvajanje dve kriptičke vrste slepića do sada nije prepoznato u našoj nomenklaturi, u ovom radu predlažemo zvanične srpske nazive za navedene vrste. Vrsta Anguis fragilis će zadržati standardno srpsko ime "Slepić", dok za vrstu Anguis colchica predlažemo ime "Istočni slepić".

Published: October 2021

This paper is focused on clarification of the basic principles for the establishment of an innovative approach in the field of landscape research through its application in spatial planning documents in Ser-bia. The key question is: how the practice of considering landscape character could direct new spatial arrangements, based on the development of strategic spatial planning documents? The paper describes the results of analysis undertaken during the development of the "Spatial plan for a special-purpose area The Cultural Landscape of Sremski Karlovci". The landscape character assessment was the main methodology taken to define value of landscape character as the starting point for defining border of cultural landscape and "representative landscape units", as well as for guiding sustainable land use management which is opposed to the traditional approach of land-use decision making. Based on landscape character value, this research provides the elements for creating a different conceptual framework for spatial planning in Serbia which is one of the most effective model of the implementation of the European Landscape Convention.
Media outlets in Vojvodina and Slovenia: Demographic-economic indicators and media pluralism

The paper analyzes the relationship between demographic-economic indicators in the Autonomous Province of Vojvodina and the Republic of Slovenia. Both societies have relatively organized regulatory and political frameworks for the development of media pluralism. It has been established that there is a clear cause-effect relation between the number of media outlets in certain local self-governments and the average net salary: the municipalities and towns with the highest average salaries also boast the highest number of media outlets. However, our analysis has shown that the criteria and mechanisms for identifying risks to media pluralism are not provided: the variety of population representing different political, ideological, cultural and social groups and the variety of interests and standpoints relevant to the local and regional community.
A forgotten tributary of the Danube: The Vajas River
Authors: Pánya István
Published: October 2021

During the examination of the historical geography of the Danube-Tisza Interfluve, the reconstruction of the medieval landscape was carried out, within which the channel conditions of the main watercourses were sketched. The Vajas River is assumed to be the most important medieval tributary of the Danube. It can be located based on historical maps, medieval and modern written sources. During the research, it turned out - based on our sources so far - that there was no tributary called Vajas on the right bank of the Danube. Only the tributaries/branches on the left bank of the river were called Vajas. The Vajas River was not uniform but consisted of at least four sections in an area of about 140 km from Kalocsa to Plavna.

The variety of etiological factors contributing to the development of distal bite various form, as well as the structures that are affected by the disorders determine the deegre of complexity of the malocclusion itself, and thus the choice of therapeutic procedure by which it will be treated. An 11-year-old female patient was diagnosed with this type of malocclusion with a certain degree of presence of other irregularities. After a detailed diagnostic procedure, and determining the type of growth, we approach the therapeutic procedure in two phases. By applying the funcional therapy in the first phase, we correct the vertical growth type, and then in the second phase of therapy using a fixed technique we achieve harmonious intermaxillary relations, an adequate molar and canine Class I relationship as well, thus improving the aesthetics of the patient's face.
Sensory processing disorders in premature infants

Introduction. Children born prematurely have an increased risk of immediate medical complications, as well as socioemotional, cognitive, linguistic and sensory processing disorders later in life. Studies have examined the effects of prematurity on developmental outcomes, such as cognition, however, there is a need for a more detailed examination of sensory processing disorders in preterm infants. Not only is prenatal neurosensory development interrupted in utero, but these children may also experience intense stimulation in the neonatal unit, which can further alter the development and function of the sensory system. Objective. The paper presents an overview of research on sensory processing disorders in premature infants, with special emphasis on the impact of the environment of the neonatal unit. Method. Insight into the relevant literature was performed by specialized search engines on the Internet and insight into the electronic database. Results. Sensory processing disorders affect 39% to 52% of newborns born prematurely, with some evidence to suggest that children born before 32 weeks are most at risk. The literature to date has consistently reported difficulties in sensory modulation of preterm infants, within the tactile, vestibular, auditory, oral, and visual domains. Conclusion. Sensory processing disorders in preterm infants appear to occur as a result of their immature neurological and biological system and being in the environment of a neonatal intensive care unit, which is unable to meet the sensory needs of preterm infants. Altered sensory experiences, during periods of neurodevelopmental vulnerability and fragility, can result in sensory processing disorders, which may include enhanced responses or less response to stimuli (hyper or hyposensitivity).

Although cerebrovascular disease may be a well recognised trigger for diabetic ketoacidosis (DKA), literature data on the precise mechanisms, characteristics, or treatment guidelines are rare. The risk of developing an ischemic stroke is doubled in adults with diabetes compared to people with normal glucose metabolism. It is important to point out that even children with DKA have a significantly increased risk of cerebrovascular insult and that they can have a stroke with a frequency of about 10%. Given the significant overlap of symptoms between these two diseases, it can be assumed that attributing DKA symptoms as a manifestation of stroke is not uncommon, especially in elderly and less communicative patients. In addition, pH, bicarbonate concentration, and anion gap are not routinely measured in all diabetics suffering from stroke, at least not in secondary health institutions.Children who develop cerebrovascular stroke during DKA often at the beginning have a preserved consciousness or only mild confusion or lethargy. After a few hours, with the institution of therapy, however, loss of consciousness may occur accompanied by signs of increased intracranial pressure. It was previously thought that the cause was too fast fluid replacement. Recent data suggest that reperfusion injury may be a more likely mechanism. Although most of these studies relate to younger individuals with ketoacidosis, it is clear that at least some of them may be operative in adult DKA. Literature therapeutic guidelines for adult diabetics with stroke-related diabetic ketoacidosis are almost lacking, although it is clear that they could not be the same as those utilised in population with normal glucose metabolism. In this paper, we have tried to define our treatment guidelines for these particular patients.

Coronavirus Disease (COVID-19) is caused by the RNA virus SARS-CoV-2. The primary receptor for the virus is most likely Angiotensin-converting enzyme 2 (ACE2), and the virus enters the body by infecting epithelial cells of the respiratory tract. Through the activation of Toll Like Receptors (TLRs), epithelial cells begin to synthesize various biologically active molecules. The pathophysiology of the COVID 19 is primarily attributed to the hyperactivation of host's immune system due to direct damage to the cells, with consequent release of proinflammatory substances, but also due to the activation of the innate immune response through the activation of alveolar macrophages and dendrite cells (DC). A strong proinflammatory reaction causes damage to alveolar epithelial cells and vascular endothelium. Respiratory epithelial cells, alveolar macrophages and DC are likely to be the most important cells involved in the innate immune response to the virus, since prolonged and excessive SARS-CoV-2-induced activation of these cells leads to the secretion of cytokines and chemokines that massively attract leukocytes and monocytes to the lungs and cause lung damage.
The prospects of the study of medieval arts in the works of Pero Slijepčević
Authors: Nikolić Časlav
Published: October 2021

The paper presents the basic positions of understanding of Serbian medieval culture and art in the works of the renowned scholar of Serbian literature Pero Slijepčević. During his life and work in Skoplje in the 1930s, Slijepčević was in direct contact with the signifiers of the Serbian cultural tradition, so he became more familiar with sacral art and architecture, history and literature of the Middle Ages. Pero Slijepčević's works on ancient Serbian art, its historical, cultural, sacral and symbolic values, are usually viewed at the margins of their author's overall and highly philological, pedagogical, cultural and social engagement. And yet, they can identify important perspectives on thought and relevant contributions to the contemporary historization of Serbian culture and art. Although these works are somehow hidden, silent in the horizon of Pero Slijepčević's overall work and engagement, his thought about the art of the Middle Ages is as much an indicator of the diversity of Slijepčević's knowledge and authentic gift for the scientific study of that art and time, as much of the depth of cultural experience. Without which even the central dimensions of literary, cultural or educational expression could not be so strongly realized.
