Published: June 2022

Стаття присвячена дослідженню впливу дефіциту бюджету на матеріально-технічне забезпечення закладів охорони здоров’я України. Обгрунтовано, що Україна суттєво відстає від своїх європейських сусідів за такими показниками, як тривалість життя та смертність. Основними передумовами високого рівня смертності є такі фактори ризику як паління, зайва вага, брак фізичного навантаження та надмірне вживання алкоголю, поряд із невирішеними проблемами стосовно поширення інфекційних захворювань і високого рівня травматизму. Україна витрачає значну частину ВВП на послуги охорони здоров’я, проте рівень ВВП на душу населення в Україні є нижчим, ніж у більшості європейських країн. Водночас, багатьом країнам вдається досягати досить хороших показників тривалості життя та смертності, маючи співставні витрати на охорону здоров’я. Система охорони здоров’я в Україні є громіздкою та застарілою і базується на моделі з жорсткими процедурами управління та фінансування. Таку ситуацію обумовлюють глибинні недоліки, накопичені у національній системі охорони здоров’я через відсутність модернізації, ігнорування потреб населення, невикористання сучасних світових тенденцій, неефективної роботи системи та високого рівня корупції. Аналіз стану матеріально-технічного забезпечення за результатами проведенної роботи показав, що в переважній своїй більшості заклади охорони здоров’я не забезпечені апаратурою для проведення діагностики або були забезпечені такою аппаратурою ще у 1990-2000 роки. З цього ми можемо зробити висновки, що наявне обладнання є морально застарілим та фізично зношеним. Тому було прийнято рішення провести заміну обладнання,  яке знаходиться в експлуатації більше 10 років. Визначено необхідну додаткову кількість обладнання для забезпечення потреб опорних закладів охорони здоров’я України у розрізі адміністративно-територіальних одиниць. Проаналізовано використання методів комп’ютеної томографії,  методів рентгенографії та ультразвукової діагностики, апаратів штучної вентиляції для лікування легень для підтвердження наявності гострої респіратоної хвороби COVID-19, спричиненої корона вірусом SARS-CoV-2. Завдяки злагодженій співпраці задіяних центральних органів виконавчої влади та органів місцевого самоврядування було досягнуто видатних результатів по оснащенню новітнім сучасним обладнанням 256 закладів охорони здоров’я по всій території України. Оцінюючи результативні показники, в статті доведено, що наразі оновлено близько 20% наявної матеріально-технічної бази.

Published: June 2022

The study of composite materials based on mechanical mixtures of microdispersed PbTe and nanodispersed additional component ZnO, TiO2, SiO2 (50-70 nm) or microdispersed CdTe (32-50 μm) was performed. The purpose of this study is to reduce the thermal conductivity of the material. Measurements of specific electrical conductivity, Seebeck coefficient and thermal conductivity coefficient of the studied samples were measured. It is established that the achievement of low values of the thermal conductivity is complicated by the processes of agglomeration of the nanodispersed component at the temperatures of production and processing of composite samples, as well as the chemical interaction of the components of the additive and matrix.

The relationship between abnormal intracranial findings in brain computed tomography and antiplatelet or anticoagulant use in patients with nontraumatic headache: a prospective cohort study
Authors: Iskorur Caner , Korkut Mustafa , Soyuncu Secgin
Published: June 2022

Objective This study aimed to investigate the relationship between abnormal intracranial findings on brain computed tomography and antiplatelet or anticoagulant use in patients with nontraumatic headache in the emergency department (ED).Methods This was a single-center prospective observational study of patients admitted to the tertiary ED with complaints of nontraumatic headache between May 1, 2016 and September 1, 2016. Anticoagulant or antiplatelet drug use by the patient was recorded. Brain computed tomography (CT) results were categorized into two groups, abnormal results (CT positive) and no pathologic results (CT negative), and compared. The CT positive group included any pathological signs in the brain and the negative group was considered a normal read. A logistic regression analysis was used for evaluating the association of antiplatelets and anticoagulants with abnormal CT findings.Results Of the 837 patients with nontraumatic headaches, 157 (18.8%) patients who underwent brain CT scanning were included. The mean age of the patients was 44.4±16.7 years. Eighty-eight (56.1%) of the patients were women. Of the 29 (18.4%) patients using antiplatelets or anticoagulants, 16 (55.2%) were in the CT positive group. There was a statistically significant difference between both groups in terms of drug use compared to the CT negative group (P<0.001). Factors affecting CT results were examined in logistic regression analysis and a statistically significant difference was found in the detection of positive results in antiplatelet or anticoagulant drug users (adjusted odds ratio, 2.478; 95% confidence interval, 1.006–6.102; P=0.048).Conclusion The use of antiplatelets or anticoagulants in patients admitted to the ED with nontraumatic headache is associated with an increased risk of abnormal intracranial results in brain CT.

In the context of a larger project whose purpose was to comparatively analyze the associations of returnees in different autonomous communities, the need arose to specifically analyze the websites of these groups from a semiotic, discursive and communicational approach. The project required the creation of an analysis model based on a bibliographic review that would allow studying the sites in a comprehensive manner and that would take into account the new communicational paradigms (web 3.0). After exploring analysis models based on obsolete paradigms (web 1.0 and web 2.0), this research shows the design and validation of a website analysis proposal, in which two perspectives are differentiated and correlated: the technical aspects of the cyber genre and its discursive characteristics.
Cristianismo e modernidade no pensamento filosófico de Henrique Cláudio de Lima Vaz
Authors: SJ João A. Mac Dowell
Published: June 2022

O artigo trata da primeira da fase, bem mais breve, do pensamento filosófico de Lima Vaz, reconhecido como um dos principais filósofos de sua geração no Brasil. Depois de fornecer algumas indicações sobre sua formação intelectual, detém-se na sua reflexão sobre as condições de reconciliação entre a mensagem cristã e o pensamento moderno através de seus artigos sobre “consciência histórica”, visando resgatar o verdadeiro sentido da modernidade. Analisa também a aplicação feita por ele dessas ideias à solução dos graves problemas da sociedade brasileira então em debate, bem como a repercussão pública de sua proposta num momento decisivo da história nacional. Discute em seguida se ele com isso se mostra então favorável a um pensamento cristão alternativo à metafísica tradicional, concluindo por uma provável negativa.

Die Hochschule zieht den Stecker
Authors: Thomsen Leon
Published: June 2022

Deutschland hat ein großes Problem. Die Energiepolitik der vergangenen Regierungen hat das Land in einem hohen Maße von Russland abhängig gemacht. Abhängig von einem Land, das seit Februar 2022 Krieg in Europa führt. Um sich unabhängiger von Russland zu machen und sich den Herausforderungen des Klimawandels zu stellen, bedarf es neuer Lösungsoptionen. Wie diese Optionen konkret aussehen könnten, ist noch ungewiss. Fest steht aber, dass Deutschland dringend Energie sparen muss. Auch der Aspekt der Nachhaltigkeit spielt eine Rolle. Die Frage, die sich stellt, ist: Was kann man auf die Schnelle tun? Dies gilt es national und auch lokal zu beantworten. Im Artikel wird diese Frage auf lokaler Ebene für den Kunst- und Mediencampus Hamburg der HAW beantwortet.
Impact of Education on Suicides in India
Authors: Sharma Priyank
Published: June 2022

Aim. The aim of this paper is to examine the impact of education on the rate of suicides in India. The paper further attempts to take a global outlook on how prevalent is suicide among countries with high education indicators.

Methodology. The paper is based on secondary research with data collected from National Databases like National Crime Records Bureau and International databases of World Health Organization and Organisation for Economic Co-operation and Development (OECD). Data analysis is done using statistical technique like Correlation and using Microsoft Excel.

Results. The study reveals that in India, the increase education levels of people have had negligible impact on the number of suicides in the country. Across states, the suicide rate and literacy rate have a positive correlation of 0.35; while correlation doesn’t mean causation and the two are mildly correlated, it does establish the fact that education doesn’t have a direct impact on the suicide rate. Also, the analysis indicates that even though the education levels in the country have risen, subsequently, the educational level among people who committed suicides also increased. Further, it is found that the countries that are ranked higher on PISA ranking and tertiary education attainment have mostly higher rates of suicide.

Conclusions. As shown throughout the study, education hasn’t been an effective instrument in equipping people with life skills: with the increase in education levels across the country, there has been an increase in the education level of people who commit suicides concomitantly, as if the education is happening in vacuum with no effect on the persona of people committing suicides. Thus, it’s significant we question our educational practices; and re-align our goals of education such that it leads to overall development of an individual.
Spherical flow diagram with finite hyperbolic chain-recurrent set
Authors: Galki Vladislav D. , Pochinka Olga V.
Published: June 2022

In this paper, authors examine flows with a finite hyperbolic chain-recurrent set without heteroclinic intersections on arbitrary closed n-manifolds. For such flows, the existence of a dual attractor and a repeller is proved. These points are separated by a (n−1)-dimensional sphere, which is secant for wandering trajectories in a complement to attractor and repeller. The study of the flow dynamics makes it possible to obtain a topological invariant, called a spherical flow scheme, consisting of multi-dimensional spheres that are the intersections of a secant sphere with invariant saddle manifolds. It is worth known that for some classes of flows spherical scheme is complete invariant. Thus, it follows from G. Fleitas results that for polar flows (with a single sink and a single source) on the surface, it is the spherical scheme that is complete equivalence invariant.
On perturbations of algebraic periodic automorphisms of a two-dimensional torus
Authors: Grines Vyacheslav Z. , Mints Dmitrii I. , Chilina Ekaterina E.
Published: June 2022

According to the results of V. Z. Grines and A. N. Bezdenezhnykh, for each gradient-like diffeomorphism of a closed orientable surface M2 there exist a gradient-like flow and a periodic diffeomorphism of this surface such that the original diffeomorphism is a superposition of a diffeomorphism that is a shift per unit time of the flow and the periodic diffeomorphism. In the case when M2 is a two-dimensional torus, there is a topological classification of periodic maps. Moreover, it is known that there is only a finite number of topological conjugacy classes of periodic diffeomorphisms that are not homotopic to identity one. Each such class contains a representative that is a periodic algebraic automorphism of a two-dimensional torus. Periodic automorphisms of a two-dimensional torus are not structurally stable maps, and, in general, it is impossible to predict the dynamics of their arbitrarily small perturbations. However, in the case when a periodic diffeomorphism is algebraic, we constructed a one-parameter family of maps consisting of the initial periodic algebraic automorphism at zero parameter value and gradient-like diffeomorphisms of a twodimensional torus for all non-zero parameter values. Each diffeomorphism of the constructed one-parameter families inherits, in a certain sense, the dynamics of a periodic algebraic automorphism being perturbed.
On the numerical solution of second-order stiff linear differential-algebraic equations
Authors: Solovarova Liubov S. , Phuong Ta D.
Published: June 2022

This article addresses systems of linear ordinary differential equations with an identically degenerate matrix in the main part. Such formulations of problems in literature are usually called differential-algebraic equations. In this work, attention is paid to the problems of the second order. Basing on the theory of matrix pencils and polynomials, sufficient conditions for existence and uniqueness of the equations’ solution are given. To solve them numerically, authors investigate a multistep method and its version based on a reformulated notation of the original problem. This representation makes it possible to construct methods whose coefficient matrices can be calculated at previous points. This approach has delivered good results in numerical solution of first-order differential-algebraic equations that contain stiff and rapidly oscillating components and have singular matrix pencil. The stability of proposed numerical algorithm is investigated for the well-known test equation. It is shown that this difference scheme has the first order of convergence. Numerical calculations of the model problem are presented.
On an iterative method for solving optimal control problems for an elliptic type system
Authors: Fairuzov Mahmut E. , Lubyshev Fedor V.
Published: June 2022

An important class of applied problems is that of optimal control of some objects’ state. It is required to select control actions in such a way as to achieve desired effect. We deal with distributed systems, since their state is described by a partial differential equation. In this paper we study an iterative process for solving the problem of optimal control for an elliptic type system. Similar problem arises during the control of thermal processes. The quality of system state control is estimated by a given quality functional defined on the solution of the Dirichlet problem for an elliptic equation. One of the most important classes of thermal process control problems is temperature control, which means maintaining given temperature in the computational domain due to certain thermal effects. Here, a distributed internal heat source acts as a control. In the paper, we study statement correctness of the optimal control problem with a regularized functional. More precisely, we examine control problem for a system described by an elliptic type equation and formulate its optimality condition in the form of a system of equations for initial and conjugate states. An iterative method is proposed for solving the optimal control problem of an elliptic type system. Convergence of the iterative process is studied, and the rate of convergence is estimated.
The issue of acidity and alkalinity in our diet – Facts, popular beliefs, and the reality
Authors: Raposa B. , Antal E. , Macharia J. , Pintér M. , Rozmann N. , Pusztai D. , Sugár M. , Bánáti D.
Published: June 2022

Several misconceptions exist about foods and nutrition. Many believe, that the human body can “acidify”, thus, an “alkaline diet” should be followed. The acid-base balance is a characteristic of a normally functioning human body. Throughout our metabolic processes, acids and substances with acidic pH are produced continuously, which, in the case of a healthy person, does not affect the pH of the human body. In those rare cases, when an overall pH imbalance evolves in the human body due to its life-threatening nature, it requires urgent medical intervention. Furthermore, it cannot be influenced by dietary interventions.

This paper highlights evidence regarding acidification and the acid-base balance, with special attention to certain food groups. Foodstuffs have different specific pH value (acid-base character), they can be acidic, alkaline, or neutral in elemental state. Beside their chemical nature, the effect they have on the human body depends on the mechanism of their metabolism, as well. Diet and ingredients have direct and indirect effects on the human body's intracellular and extracellular compartments (especially blood and urine), still they do not influence its pH significantly.

Alkaline diets were born in the absence of evidence-based information and/or the misunderstanding and wrong interpretation of the available and up-to-date scientific facts. The convictions of consumers and the promotion of the alkaline diet lack the scientific basis, so it can be harmful or even dangerous in the long run.

In summary, scientific evidence on the efficacy or prophylactic effects of an alkaline diet is not available.

Published: June 2022

Tomato spotted wilt virus (TSWV) is economically prominent disease for its impact on tobacco (Nicotiana tabacum L.) production worldwide. An increase of the incidence of symptoms typical of TSWV has been observed in tobacco production areas in Denizli province of Turkey where tobacco is significantly grown. Surveys were conducted to determine the prevalence status of TSWV in tobacco cultivars and its possible sources of infections in four tobacco growing districts of Denizli province. A total of 501 plant samples from field-grown tobaccos, weeds, potential intermediate hosts, seedlings and seeds were collected during 2019 and tested by DAS-ELISA. Of these plants, 243 belong to 55 different weed species from 26 different families with intermediate host potential. Throughout the study, 40 crop plant samples which could be intermediate hosts and 39 tobacco seed samples were also taken for testing. Adult thrips specimens were picked up from the fields and brought to the laboratory for preparations. Four vector virus species were detected when adult thrips individuals were diagnosed: Thrips tabaci Lindeman (Thysanoptera: Thripidae), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), Aeolothrips intermedius Bagnall (Thysanoptera: Aeolothripidae) and Thrips major Uzel (Thysanoptera: Thripidae). Of the 179 tobaccos sampled, 31.2% was positive; besides, of 243 weeds tested 10 were found to be infected. Echinochloa crus-galli and Tordylium apulum were determined to be new host recordings for TSWV infection. Only one tomato plant from the crop plants as intermediate hosts was infected. Cucumber mosaic virus (CMV), Alfalfa mosaic virus (AMV) and Potato virus Y (PVY) was also confirmed in tobacco fields.
The effectiveness of Rhizobium bacteria on soil fertility and sustainable crop production under cover and catch crops management and green manuring
Authors: SUN Wenli , SHAHRAJABIAN Mohamad H.
Published: June 2022

The ability of adaptation of Rhizobia in diverse environment namely, soil, rhizosphere and grown within legume roots may lead to nitrogen fixation, in a complicated process which contain a coordinated exchange of signal between plants and the symbionts. Green manures, cash and cover crops have significant role in soil fertility. Green manuring techniques also can decrease biomass burning known as main source of air pollutant in the atmosphere. Catch crops have positive effects on both physical and chemical properties of soil, subsequent crop yield, decrease nitrogen leaching into the ground water, decrease soil erosion, and decrease nitrogen losses in cropping systems. Cover crops are those crops which cover the ground and protect loss of plant nutrients, the soil from erosion, decrease rate of soil moisture by evaporation, lower ground temperature and improve weed control and nutrient recycling. Rhizobia produce Nod factors during the early development of nodules upon perception of flavonoid molecules secreted by legume roots, and Nod factor’s structure dependents on species, chemical, substitutions added which may influence legume specificity. The benefic effects of rhizobia may depend on rhizobium strain, the genotype of the legume, management practices and bio-physical environment. Rhizobium can directly promote both plant growth and plant health, and modulating root architecture and growth via the release of plant phytohormones. In this manuscript, we want to review the most important advantages and benefits of green manures, catch and cover crops with considering the positive effects of rhizobium on soil fertility and sustainable agricultural production.
Alleviation of salinity triggered oxidative damage and photoinhibition in Vigna radiata by individual and combined treatments of selenium and jasmonic acid
Authors: ALRASHIDI Ayshah Aysh
Published: June 2022

Experiments were performed to evaluate the effect of selenium (Se) and methyl jasmonate (Me-JA) in alleviating the salinity (100 mM NaCl) stress triggered decline in growth and photosynthetic in Vigna radiata. Salinity stress significantly reduced the growth measured in terms of plant height and dry mass which was significantly alleviated by Se and /or Me-JA. Treatment of Se and Me-JA increased the synthesis of prototoporphyrin IX (Proto IX), Mg-prototoporphyrin IX (Mg-Proto IX), chlorophylls and carotenoids, increased photosynthesis and PSII activity. Besides, the supplementation of Se and Me-JA significantly declined the reactive oxygen species (H2O2 and O2-) levels causing increased membrane stability. Treatment of Se and MeJA up-regulated the antioxidant system by increasing the activities of superoxide dismutase, ascorbate peroxidase and glutathione reductase, and the content of ascorbate and glutathione in both control and salt stress treated plants. The Se and Me-JA treatment significantly increased the synthesis of total phenols and flavonoids reflecting in increased total antioxidant activity. Accumulation of proline, sugars, glycine betaine and the activity of γ-glutamyl kinase was significantly improved in Se and Me-JA treatments affecting the tissue water content. Decline in nitrate reductase activity due to salinity stress was alleviated significantly due to Se and Me-JA treatment. Vigna radiata plants treated with Se and Me-JA accumulated less Na and more K and N compared to salt stressed plants.

The usage of biofertilizer as alternative or support to mineral fertilizer encourage continuously due to fertilizer cost and environmental pollution. The effect of three phosphorus doses (0, 30, and 60 kg ha-1 P2O5) with a control and different commercial biofertilizers, Bontera (Bacillus amyloliquefociens, Bacillus pumilus, Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Trichoderma harzianum, Trichoderma kanigi), Bactoboost (Bacillus subtilis, Bacillus magaterium, Loctococcus spp.), Koklendirici (Bacillus subtilis, Bacillus magaterium, Loctococcus spp.), Lifebac NP (Bacillus subtilis, Bacillus magaterium), natural organic matter and humic substances (NSAH) (15% organic matter, 6% organic carbon, 13% humic + fulvic acid), and Rhizobia  (Rhizobium leguminosorum)) were investigated. Increasing phosphorus doses positively affected all the investigated characters. Koklendirici biofertilizer positively affected the important yield components, but highest grain yield was determined in the NSAH plots. Increasing phosphorus (P) doses did not affect nitrogen (N), potassium (K), magnesium (Mg), and copper (Cu) contents of the grain while phosphorus, calcium (Ca), iron (Fe), manganese (Mn), and zinc (Zn) contents showed an increase. Difference in climate might have influenced these results. These results indicated that understanding of bio and mineral fertilizer would enable us to use biofertilizer as an alternative to mineral fertilizer to common bean production.

Sixteen plum and eleven sweet cherry newly established commercial orchards in Transylvania, Romania, were the subject of the survey during the vegetative periods of 2020-2021 in order to assess the occurrence of different virus infections. Two blocks of 200 trees from each orchard were monitored by visual observation for virus-like symptoms, especially for Plum pox virus (PPV) in plum orchards. Twenty trees of each plum orchard were then sampled and tested for serological detection of PPV, Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), Apple chlorotic leaf spot virus (ACLSV), Apple mosaic virus (ApMV) and Myrobalan latent ringspot virus (MLRSV). Similarly, ten trees of each sweet cherry orchard were sampled and tested for the presence of PDV, PNRSV, ApMV, ACLSV, PPV, Arabis mosaic virus (ArMV), Cherry leaf roll virus (CLRV), Raspberry ringspot virus (RpRSV), Strawberry latent ringspot virus (SLRSV) and Tomato black ring virus (TBRV) by serologic assays. Additionally, a few sweet cherry trees suspected to be infected by Little cherry virus-1 (LChV-1) were tested by molecular assay. Unexpectedly, no plum orchards were found to be free of PPV.  The average level of PPV infection was 32%. PNRSV occurred in 8.1% and PDV in 1.2% of sampled plum trees. Four out of ten viruses were detected in sweet cherry sampled: PDV (3.6%), ACLSV (0.9%), RpRSV (0.9%) and TBRV (0.9%). No infection with ACLSV, ApMV and MLRSV in plum and PPV, PNRSV, ApMV, ArMV, CLRV, SLRSV and LChV-1 in sweet cherry was detected. Mixed infections occurred at 4.8% in plum, and at 0.9% in sweet cherry trees sampled. The average occurrence of viruses in plum and sweet cherry orchards surveyed in Transylvania was determined at 41.3%, and 6.3% respectively. Overall results revealed a critical situation especially in regards to PPV infections making the success of fruit production in the most surveyed plum orchards quite problematic. Virus infections level in the younger sweet cherry orchards were significantly lower.
A New Novel Synchronization Index of Brain Networks in Hyperbolic EEG Dynamics
Authors: DEMİRER Rüştü Murat
Published: June 2022

The functional connectivity of brain connectivity changes its pattern over time i.e. dynamics, even in the resting state with an infinite number of degrees of freedom with local couplings. Recently, quantifying the level of synchrony has received considerable attention. We hypothesized that time-varying instantaneous phase synchronization over local couplings are defined in hyperbolic space and different brain regions can identify failures, flexibility, and stability in network dynamics. Our goal is to understand the phase synchronization changes of the beta-gamma band, and in addition, to investigate Shannon entropy based on phase synchronization stability. Whole EEG dynamics from local phase synchronizations was used to detect treatment resistance from both hemispheres in OCD patients. Temporal filtering and Hilbert transforms were performed to infer beta-gamma band phase difference activity from the EEG brain dynamics. Then, the response beta-gamma band phase stability was quantified using a new phase synchronization index (PSI). Results indicated significantly changed phase synchronization of the response and non-response to treatment, patients in OCD patients in F7 electrode. Greater phase fluctuations of beta-gamma synchronizations in treatment resistance OCD is claiming phase deficiencies within neural populations. This study first provides experimental and theoretical support for characterizing cycle structure depends on the non-Euclidian dynamics of neural phase synchrony caused by disturbances of underlying neurotransmitter systems, as reflected in different normal and disease states.

Published: June 2022

Background: As the number of people working from home has increased since the COVID-19 pandemic, it is important to understand workers’ stress and psychological state while working from home. Work-family conflict and loneliness may be related to working from home, and they could be experienced differently depending on individual traits. Therefore, this study examined the parallel multiple mediating effects of work-family conflict and loneliness in the relationship between personal temperaments and negative emotions such as depression and anxiety.Methods: Data were collected online from people currently working from home for at least one month, more than once per week. They answered K-DASS-21, UCLA loneliness scale, Work-Family Conflict, and FCB-TI. Only four temperaments were used in the statistic step: Briskness and Sense sensitivity as protective factors and Perseveration and Emotional reactivity as vulnerable factors. The multiple mediating effects were analyzed independently by using the PROCESS macro.Results: Firstly, Briskness and Sense sensitivity were found to negatively affect depression and anxiety while working from home by significantly mediating work-family conflict and loneliness. Thus, these temperaments would be protective factors while working from home. Secondly, Perseveration and Emotional reactivity positively influenced both negative emotions by mediating two mediation variables, which means that both temperaments are vulnerable factors.Conclusions: The results suggest that personality traits can impact how people experience stress and negative emotions in working situations, leading to negative psychological states. Consequently, personal temperaments would be important to understand relationships between environments and internal experiences.

Authors: Ko Eun
Published: June 2022

Background: The onset age of stroke is decreasing, leading to social loss. As such, primary stroke prevention is important. This study aimed to compare the stroke knowledge, health beliefs, and stroke prevention behavior between early and middle-aged adults.Methods: In this cross-sectional descriptive study, a survey was conducted in three small cities in Korea from June to October 2020. The study used a structured self-report questionnaire that included items on stroke knowledge, including risk factors, warning signs, and urgent action, health beliefs, and stroke prevention behavior, as well as collected data on respondents’ demographic characteristics. The data were analyzed with descriptive statistics, t-test, 2 test, and Pearson’s correlation coefficients using IBM SPSS Statistics for Windows, Version 26.0.Results: The participants included 104 early adults (aged below 40 years) and 143 middle-aged adults (aged 40∼64 years). The two groups showed a significant difference in their health beliefs scores. By contrast, they did not show a significant difference in their scores for stroke prevention behavior. However, their scores for health responsibility (t=−2.00, p=.047), nutrition (t=4.24, p＜.001), and interpersonal relationships (t=2.04, p=.042) were significantly different.Conclusions: Early and middle-aged adults showed differences in health beliefs and the stroke prevention behavior subfactors of health responsibility, nutrition, and interpersonal relationships. The present findings may be used when planning interventions or education programs for primary stroke prevention.

Objective: to characterize the dynamics of COVID-19in the municipality of Bagé, construct a detailed x-ray of the spread of the virus and analyze the impacts of the containment measures imposed by the state and municipal governments on contamination. Simultaneously, a series of social events and the behavior of the population against these measures are analyzed, to relate their impacts on the spread of the virus. Methods: the research was characterized quali-quantitatively, with an analysis period between March 2020 and April 2021. Data from daily records of new cases, active, cured and suspected cases, numbers of deaths, clinical beds and vacancies in ICU, together with social isolation data. Results: given the analyzed data, there was evidence that the measures adopted by public management had an impact on the spread of the virus, in addition, four phases of population behavior were observed during the pandemic in the municipality: fear, uncertainty, relaxation and lack of control. Conclusions: the measures of flexibility  adopted by the government generated sharp peaks in contamination and  after these peaks, it was not possible to significantly reduce the number of active cases of the disease in general, indicating the decisions of the government  had generated uncertainly in part of the population and made it impossible to effectively control the spread of the virus in the period analyzed.

Objective: to evaluate the effects of the COVID-19 pandemic on the mental health of university students at Rovuma University, in Mozambique. Methods: this is a cross-sectional qualitative-epistemological study, using a semistructured interview, answered in 2021 by six students from the Rovuma University-Mozambique, enrolled in different courses. The interviews were conducted at the university and took an average of 55 minutes. Results: the COVID-19 pandemic has seriously affected the mental health of university students. The cancellation of face-to-face activities imposed by the pandemic impacted the routine of students because of the sudden change and distance from colleagues and teachers. The fear of contamination, uncertainty about the end of the pandemic and the return of classes and prolonged social distancing were part of the mental health risks. With the resumption of classes in the remote modality, many students went through other experiences and difficulties in accessing the platform because many of them did not have the means (computer, tablet or mobile phone) and quality internet or because they lacked knowledge of information technologies and communication. Conclusion: in this period of the COVID-19 pandemic, many students went through experiences of stress, anxiety, and fear of contamination by the disease. There are no psychological care and support services within the university to respond to the demands of the pandemic and other situations that impact the mental health of the university community. It is therefore suggested that universities promote psychological and social support services to the academic community.
Urban Refugees’ Digital Experiences and Social Connections During Covid-19 Response in Kampala, Uganda

Published: June 2022

The Covid-19 crisis and its aftermath challenged economies and societal sectors globally. Refugees in developing countries are particularly vulnerable to the socio-economic impacts of the Covid-19 pandemic. In Uganda, refugees significantly compose the marginalized urban population, dependent largely on the informal sector, and are severely affected by the crisis amidst limited social protection interventions. This article draws on key informant interviews with refugees and refugee-led organizations to examine the diverse ways through which social capital within refugees and host communities in Kampala enabled and shaped digitally mediated responses to sustain livelihoods, social wellbeing, and access to information and economic resources in the wake of the pandemic. The findings indicate that digitally enabled and mediated social networks and/or connections through bonds, bridges, and links are crucial in supporting refugees to cope with crisis effects. Networks of friends, families, and institutions are sustained by digital spaces that support the everyday lives of urban refugees through communication, social protection, livelihood continuity and recovery, and service improvisation during and after the crisis. The fragmented digital infrastructure, digital divide, limited government support, language barrier, and circulation of fake news challenged the utility of digital social networks in mobilizing support for refugees during the crisis. Digital technologies offer opportunities to strengthen social support and potentially mobilize refugee livelihoods in cities with fluid programs for displaced communities. The best practices around sustained multi-platform communications, technological innovations, data collection, and robust community engagement should be leveraged to garner the opportunities offered by technologies towards stimulating inclusive crisis responses.
Closing the Implementation Gap: Obstacles in Reaching Net-Zero Pledges in the EU and Germany

The European Union and Germany have recently committed themselves to greenhouse-gas neutrality by 2050 and 2045, respectively. This substantially reduces their gaps in ambition to the Paris climate goals. However, the current climate policy mix is not sufficient to reach these targets: There is a major implementation gap. Based on economic, legal, and political science perspectives, this article identifies key obstacles in legislating stringent climate policy instruments and making them effective. Using a simple framework, we map the stage of the process in which the obstacles are at work. Moreover, we discuss the potential effectiveness of a select list of prominent drivers of climate-related regulation in overcoming said obstacles and conclude by pointing towards conditions for closing the implementation gap. In doing so, we focus on the current legislative processes of the “Fit-for-55” package by the European Commission and the 2021 Federal Climate Change Act in Germany. Our analysis builds on the extant literature, and we suggest avenues for further research.
Making Polar and Ocean Governance Future-Proof
Authors: Hansen-Magnusson Hannes
Published: June 2022

Governance institutions of the polar regions, as well as global oceans, may hold room for improvement in terms of effectiveness but, on the whole, their existence can be regarded as a success story. The arrangements managed to pool responsibility for regional resources amid Cold War geopolitics, mostly by delegating discussions to science committees. Changing global climate, however, provides considerable challenges to these governance arrangements. It begs the question of how the success story can be continued into the future. After sketching the emergence of polar and ocean governance and their core organizational principles during the 20th century, this article identifies some of the challenges linked to global warming that have been altering the context of governance fundamentally. The article discusses emerging issues that warrant attention, but which may be difficult to accommodate in present governance networks. Ultimately, the article argues that anchoring principles of “responsibility” that take into account the relational quality of polar and ocean spaces is key to any institutional design that seeks to take governance arrangements into the 21st century and beyond.
Authority in Ocean Governance Architecture
Authors: Mondré Aletta , Kuhn Annegret
Published: June 2022

In this article, we demonstrate that the ocean is a space of politics and explore the what, who, and how of ocean governance. We first sketch the governance architecture and examine challenges and shortcomings concerning political authority. Starting from a definition of “ocean governance,” we highlight that two fundamentally different regulatory approaches are applied to the ocean: a spatial ordering on the one hand and a sectoral segmentation on the other. States are the central actors regulating the use and protection of marine areas, but state sovereignty is stratified, with diminishing degrees of authority farther from the shoreline. As vast marine spaces are beyond the exclusive control of any given territorial state, political authority beyond areas of national jurisdiction must first be created to enable collective decision-making. Consequently, a multitude of authorities regulate human activities in the ocean, producing overlaps, conflicting policies, and gaps. Based on recent contributions to the fast-growing ocean governance research field, we provide a thematic overview structured along the dimensions of maritime security, protection of the marine environment, and economics to unveil patterns of authority in ocean governance.
