The problem of a hydrogen atom in a cavity: Oscillator representation solution versus analytic solution
Authors: Chaudhuri Sid
Published: April 2021

A solution to the problem of a hydrogenic atom in a homogeneous dielectric medium with a concentric spherical cavity using the oscillator representation method (ORM) is presented. The results obtained by the ORM are compared with a known exact analytic solution. The energy levels of the hydrogenic atom in a spherical cavity exhibit a shallow-deep instability as a function of the cavity radius. The sharpness of the transition depends on the value of the dielectric constant of the medium. The results of the ORM agree well with the results obtained by the analytic solution when the shallow-deep transition is not too sharp (i.e., when the dielectric constant is not too large) for all values of the cavity radius. The ORM results in the zeroth order approximation diverge significantly in the region of the shallow-deep transition (i.e., for the values of the radius where the shallow-deep transition occurs) when the dielectric constant is high and as a result the transition is sharp. Even for the sharp transition, the ORM results again agree very well with the analytic results at least for the ground state when a commonly used approximation in the ORM is removed. The ORM methodology for the cavity model presented in this article can potentially be used for two-electron systems in a quantum dot.
Effect of orifice spacing on twin circular parallel compressible jets
Authors: Satya Prakash K. B. V. , Lovaraju P. , Rathakrishnan E.
Published: April 2021

The interaction of Mach 0.5, 0.8, and 1.0, parallel, twin circular jets issuing from orifices with center-to-center spacing S/D, where S is the center-to-center distance and D is orifice diameter, 2, 4 and 6 has been investigated experimentally. The characteristics of twinjets are analyzed based on the centerline Mach number decay, exit Mach number and ratio of orifice spacing. As the spacing between the orifice increases, the maximum Mach number point of the combined jet moves downstream. For the Mach numbers studied it is found that as the S/D increases the effect of the counter-rotating vortices on jet mixing decreases. The rate of the twinjet interaction also decreases with S/D increase. As the jets propagate downstream their center-to-center distance decreases continuously and the jets merge to become single jet, for all S/D studied.

Published: April 2021

Objective: to estimate the adherence to hepatitis B vaccine in homeless people. Methods: a cross-sectional study with 90 homeless people, with the collection of 5 ml of blood for the detection of antibody against the surface antigen of the hepatitis B virus. Results: of the total, 89 (98.9%) were vaccinated with the first dose; of these, 45 (50.7%) had antibodies against hepatitis B virus surface antigen lower than 10 IU/L; 25 (53.3%) received the second dose of hepatitis B vaccine, and nine (45.8%) participants received the third dose of vaccine. Individuals who were related to both genders were more likely to adhere to the full hepatitis B vaccine schedule. Conclusion: the low adherence to hepatitis B vaccination and the small number of participants with antibodies that confer immunity against this infection were evidenced.
High Rise Buildings: Design, Analysis, and Safety
Authors: Imad Shakir  , Mohammed Ahmed Jasim  , Sardasht S. Weli
Published: April 2021

High-rise buildings have been rapidly increasing worldwide due to insufficient land availability in populated areas and their primary role as essential buildings in modern cities and capitals. However, high-rise buildings are very complicated due to the huge number of structural components and elements unlike low-rise buildings, as well as these high-rise buildings demand high structural stability for safety and design requirements. This paper aims to provide brief information about high-rise buildings regarding the basic definition, safety features, structural stability, and design challenges. A brief description of existing structural systems that are available in the literature is presented to articulate a technical issue that has been widely reported, named, adopting an effective structural system for resisting lateral loads resulting from wind and seismic activities. Consequently, a general overview is presented that covers the behavior of various structural systems for different heights of high-rise buildings by implementing a number of nonlinear static procedure analyses (pushover) and nonlinear dynamic procedure analyses (for wind and earthquake loading). Finally, a critical review of the available simplified model and seismic energy base design are also presented. This paper is intended to help in the development and application of construction systems for high-rise buildings in the future.
“Don’t Be Abashed Reading This”: Shadow of Barkov in the Texts of Dostoevsky
Authors: Andrianova Irina
Published: April 2021

The subject of research in this article is a partially crossed out portion of a letter from Fyodor Dostoevsky to his brother Mikhail dated September 30, 1844. This letter communicates his decision to leave the military service and devote himself to professional literary work. The entry was first reproduced in the edition of Dostoevsky's correspondence prepared by A. S. Dolinin, and then in the academic Complete Works. However, this was done with distortions and without proper commentary. As a result, the entry was perceived by readers as a rude expletive, which included slang, obscene vocabulary, and insults to the guardian of the Dostoevskys, P. A. Karepin, who opposed the switch of his ward to a literary path and was in no hurry to provide him with financial assistance. Textual analysis of the record about Karepin demonstrated that the strikethrough was made twice — by Dostoevsky himself at the time of writing the letter, and almost 40 years later by his widow, who was preparing the letters for publication. Due to her shyness, A. G. Dostoevskaya could not tolerate obscene words contained in the body of the letter, and she removed them with a thick strikethrough, while encrypting their meaning using shorthand. The restoration of the complete record made it possible to determine the source of the quote, namely, the “indecent” poem “Luka Mudishchev,” written in the post-Pushkin period and attributed to Ivan Barkov, but not written by him. The fact that Dostoevsky knew this poem by 1844 narrows down the range of its dating. In the heat of his “struggle” with Karepin, who criticizes the “abstract laziness and bliss of Shakespeare's dreams,” the novice writer turns the obscene satirical language of Barkoviana against his guardian in a sharp pamphlet style. Continuing his observations on common people's speech in the Siberian Notebook and the Writer’s Diary, Dostoevsky came to a paradoxical conclusion about the combination of profanity and chastity in the Russian people. The writer’s viewpoint on this matter was not clear to his contemporaries and was ridiculed in journalism and caricature.
Phage composition of a fermented milk and colostrum product assessed by microbiome array; putative role of open reading frames in reference to cell signaling and neurological development
Authors: Pacini Stefania , Ruggiero S Marco
Published: April 2021

Bacteriophages (phages), Earth's most numerous biological entities, are natural constituents of alimentary matrices; in this study we describe the characterization of phage populations in a product obtained by fermentation of bovine milk and colostrum. Such characterizations were achieved using a microarray consisting of a chip covered in short DNA sequences that are specific to certain target organisms for a total of approximately 12,000 species. The only viruses evidenced by the array belonged to Siphoviridae, the largest phage family that targets bacteria and archea. The array yielded 27 iterations corresponding to a unique target. We discuss the putative role of some open reading frames of these phages in conferring health-supporting properties with particular reference to cells signaling and neurological development. We also describe the in vitro interaction of this fermented product with alpha-N-acetylgalactosaminidase, an enzyme whose activity in serum is elevated in neurodevelopmental disorders.
Rural-Urban Differences in Changes and Effects of Tobacco 21 in Youth E-cigarette Use
Authors: Dai Hongying , Chaney Lisa , Ellerbeck Edward , Friggeri Ressa , White Nancy , Catley Delwyn
Published: April 2021

BACKGROUND:

The prevalence of current electronic cigarette (e-cigarette) use has increased dramatically among US youth. It is unknown how the impact of policies to curb e-cigarette use might differ across rural and urban areas.

METHODS:

Data were collected from an annual statewide survey of middle and high school students in Kansas. Multivariable logistic regression was performed to examine the temporal change in current e-cigarette use in 2018 and 2019 across rural and urban areas and across the areas with and without a Tobacco 21 (T21) policy that raises the minimum age of tobacco sales to 21 years.

RESULTS:

Of 132 803 participants, the prevalence of current e-cigarette use increased from 8.2% in 2018 to 12.6% in 2019. The increase was larger in rural areas (from 6.7% in 2018 to 13.4% in 2019, difference = 6.7%) than in urban areas (9.8%–11.9%, difference = 2.1%), with a significant interaction effect of year × urbanicity/T21 group (P < .0001). In urban areas, e-cigarette use increased significantly for middle school students in T21 areas (3.3%–4.5%; P = .01) and all students in non-T21 areas (8.1%–12.0%; P < .0001). In rural areas, the increase in e-cigarette use was significant in both T21 and non-T21 areas for all students, but the increase was smaller in T21 (7.9%–10.8%, difference = 3.0%) than in non-T21 areas (6.5%–13.7%, difference = 7.1%).

CONCLUSIONS:

In this study, we reported marked disparities in the increase of youth e-cigarette use, with a larger recent increase in rural than in urban areas. T21 policies appear to mitigate these increases in both rural and urban youth.
Авіаційний тиждень на Південноросійській обласній сільськогосподарській, промисловій і кустарній виставці 1910 р. у Катеринославі: проект, який не здійснився
Authors: Савчук В. С.
Published: April 2021

Мета статті – з’ясувати малодосліджені події повітроплавного та авіаційного життя Катеринослава в контексті світового розвитку авіації, визначити події, які привели до виникнення проекту проведення авіаційного тижня у Катеринославі та перебіг процесу його підготовки. Для досягнення мети дослідження використано аналітико-синтетичній, історико-хронологічний, порівняльно-історичний, логічний методи, метод синхронізації. Висвітлено події світового та вітчизняного рівня, які передували появі цього проекту. Визначено історіографію дослідження, доведено, що поряд з незначною кількістю публікацій, які розглядають розвиток авіації у Катеринославі, вони мають більше публіцистичний, ніж науковий характер. Зазначено ініціюючу роль цих публікацій для подальших досліджень. З’ясовано вплив Південноросійської обласної сільськогосподарської, промислової і кустарної виставки, яка відбулася у Катеринославі з липня 1910 р. по 10 жовтня 1910 р., на зародження ідеї проведення авіаційного тижня у Катеринославі та перебіг його підготовки. Висвітлено невідомі раніше факти активної реакції авіаторів, виробників літаків та авіаційних установ і об’єднань на можливість участі у Південноросійській обласній сільськогосподарській, промисловій і кустарній виставці. Наведено численні факти відповідних пропозицій щодо участі у виставці і доведено, що така активність сприяла висуненню проекту проведення міжнародного авіаційного тижня під час виставки. Показано, що планований авіаційний тиждень дійсно мав би міжнародний характер, міг відбутися за участю відомих авіаторів-пілотів (зокрема таких знаних у світі як С. І. Уточкін, Е. Жільбер), на ньому був би представлений широкий спектр конструкцій, здатних підняти людину і вантажі у повітря. Серед них повітряні кулі, дирижаблі, літаки різноманітних конструкцій тощо. Доведено, що планований міжнародний авіаційний тиждень такого масштабу був би першим в Україні і другим у Російській імперії. Здійснення цього проекту могло б зробити цю виставку непересічною історичною подією в розвитку авіаційної справи в Україні. Визначено причини, які в останній момент спонукали Розпорядчий комітет виставки відмовитися від реалізації цього проекту. Висловлено думку, що незважаючи на те, що даний проект не було здійснено, є всі підстави для твердження про його значимість для розвитку авіаційної справи в Україні. Ключові слова: Катеринослав, Південноросійська обласна сільськогосподарська, промислова і кустарна виставка, авіаційний тиждень, проект, авіаційна спільнота, фінансування, авіатори, літаки, дирижаблі.

Authors: Світленко C.
Published: April 2021

Метою статті є висвітлення формування і становлення особистості О. А. Тищинського (1835–1896) як українського народолюбця другої половини ХІХ ст. Методами дослідження стали історико-генетичний, історико-типологічний, персоналі- стичний. Джерела: архівні документи з фондів ІІІ відділу Власної його імператорської величності канцелярії та Особливого присутствія Правительствуючого Сенату Російської імперії, опубліковані спогади М. М. Грінченко та А. В. Верзиліва, С.Ф. Русової, автобіографічні нотатки П.С. Єфименка, творчі матеріали О. А. Тищинського, епістолярії О. Я. Кониського, А. П. Свидницького тощо. Основні результати полягають у тому, що автор з’ясував, що формування світогляду Олександра Тищинського відбувалося під впливом кількох важливих ідейних чинників, зокрема ліберальних ідей оновлення суспільства на основі утвердження конституційного способу правління; поглядів радикальної демократії, які популяризувалися «Колоколом» О. І. Герцена та М. П. Огарьова; українських народолюбних впливів, які спричинили формування зацікавленості українським фольклором і письменством, а особливо поезією Тараса Шевченка. Діяльність О. А. Тищинського як українського народолюбця зародилася в період його участі в Харківсько-Київському таємному товаристві (1856–1860), а утвердилася на початку 1860-х  рр. – у часи діяльності в Чернігівській українській громаді. Як український національний демократ, О. А. Тищинський займався педагогічною, публіцистичною та громадською національно-культурницькою діяльністю, хоча його радикально-демократичні симпатії обумовлювали зв’язки з російськими землевольцями. У 1870–1880-х рр. український діяч був серед найактивніших організаторів Чернігівської громадської книгозбірні та книгарні, відстоював інтереси народу в лавах Чернігівського повітового земства, сприяючи поступу народної освіти, охорони здоров’я тощо. У 1890-х рр. О. А. Тищинський належав до тих діячів, які відновили Чернігівську українську громаду. Стислі висновки. Доведено, що О. А. Тищинський, незважаючи на впливи російської радикальної демократії, сформувався як діяч українського національно-демократичного руху, який від початку 1860-х і до середини 1890-х рр. належав до найпомітніших й найавторитетніших українських народолюбців Чернігівщини, зробив свій внесок у розвиток українського національного культурництва в цьому краї. Практичне значення статті в тому, що її матеріал представлятиме інтерес для студентів, аспірантів, докторантів та фахівців-істориків у процесі вивчення етнонаціональної та суспільно-політичної історії України ХІХ ст. Оригінальність статті полягає в осягненні маловивчених аспектів світогляду й діяльності українського діяча. Наукова новизна в актуалізації життя та діяльності О. А. Тищинського як українського національного демократа другої половини ХІХ ст. Тип статті: описово-аналітичний.
The patent-license system of Ukraine in the second half of the XX century
Authors: Tverytnykova E. , Gutnyk M.
Published: April 2021

The formation of the patent-licensing system of Ukraine during the second half of the XX century is investigated. It is established that the first funds of technical literature, which was necessary for patent work, were created in the departments of the institutes of the Academy of Sciences of the USSR in the first postwar years. For example, the fund of scientific and technical literature, documentation, patents and inventions began to form in the Institute of Electrical Engineering of the USSR. It was established in 1944. But various special centers for providing information support for the development of the patent and license business were organized a somewhat later. In particular, at the Institute of Electrical Engineering of the Academy of Sciences of the USSR only 20 years later in 1964. Employees were making a preliminary examination of applications for inventions and expanding the funds of scientific and technical documentation, were completing foreign patent documentation from foreign countries.

A network of special Patent Departments was created on the basis of the higher technical institutions. A small group for the systematization of patent information was created at the Kharkiv Polytechnic Institute in 1967. In 1971, the patent office was also established at the Odessa Polytechnic Institute. In 1974, at the Kyiv Polytechnic Institute an organizational and analytical department was created, it contributed to the development of inventive activities of the Institute. The intensification of inventive search occurred in the 1980s and was aimed at improving quality, which contributed to the creation of prospective, competitive world-class developments and their introduction into industry.

During this period, the vast majority of scientists took part in patent and licensing activities, a large number of patents were obtained and scientific and technical cooperation was started on a commercial basis with the conclusion of licensing agreements. A number of devices were patented in the following countries: Spain, Italy, England, Switzerland, Japan, Germany, Hungary, Poland, Bulgaria and others. In the early 1990s, the situation with inventive and patent licensing activities changed. A significant reduction in the number of inventions demonstrated the general state of scientific research in the country.
Реформування оборонно-промислового комплексу України: успіхи та невдачі у контексті воєнно-політичного діалогу з НАТО
Authors: Попко С. М.
Published: April 2021

Проаналізовано стан українського ОПК у контексті євроінтеграційних намірів української держави. Зазначено, що у 1990–2000-х рр. Україна мала розгалужений, нерівномірно розвинений, недостатньо скоординований ОПК, який характеризувався незбалансованістю структури оборонних виробництв, високим рівнем зношеності основних фондів, низькою рентабельністю роботи більшості підприємств та низьким рівнем завантаження виробничих потужностей. Зазначено, що реформування ОПК повинно відбуватися синхронно, на тлі вступу нашої держави до НАТО, адже Альянс – певний сигнал іноземним інвесторам для приходу в Україну, що, у в свою чергу, покращить міжнародний інвестиційний імідж України та дозволить збільшити надходження до бюджету за рахунок заощаджень на обороні. Зауважено, що українській владі необхідно посилити державний протекціонізм з метою підвищення результативності заходів з просування вітчизняної оборонної продукції, технологій і послуг на перспективні сегменти світового ринку озброєнь шляхом підтримання маркетингової діяльності, координації та фінансування участі національних делегацій у міжнародних виставкових заходах. Наведено приклади успішних підприємств ДК «Укроборонпром», зокрема у сфері виготовлення та поставку авіаційних керованих ракет, послуг з ремонту та модернізації бойових літаків і гелікоптерів тощо.

Published: April 2021

Objetivo Identificar barreras negativas de riesgo para la prevención y control del dengue que prevalecen en la población y en los responsables institucionales y sectoriales de la ciudad de Cartagena.Materiales y Métodos Se utilizó un enfoque cualitativo de diseño narrativo-etnográfico apoyado en la metodología COMBI. La población fue de 90 personas residentes en tres localidades comuneras del Distrito de Cartagena de Indias, Colombia, registradas en el Sistema Nacional de Vigilancia en Salud Pública (Sivigilia) y que tuvieran una alta incidencia o fueran un caso sospechoso de fi ebre de dengue y casos de dengue.Resultados Las personas residen en viviendas de cartón, madera, zinc, block, cemento, eternit y albergues. A pesar de que tienen conocimiento de la problemática del dengue, la relacionan con otras enfermedades como el resfriado y la gripe. Le dan más importancia a otros problemas sociales, como la violencia y la inseguridad en la zona. Los mensajes educativos y preventivos en prensa, radio y televisión emitidos por el DADIS y otros entes de control del dengue no cubren todas las medidas que se deben implementar para la prevención y control de la enfermedad.Conclusión La transmisión del dengue se relaciona con factores socioeconómicos como el poco conocimiento que tiene la comunidad sobre las consecuencias de la transmisión del dengue en la salud, la actitud y prácticas indiferentes ante esta patología, así como la insuficiente comunicación educativa y preventiva que realiza el DADIS a través de los canales de comunicación y redes sociales, entre otras.
Can socioeconomic factors influence the establishment of information mutation in local medical systems? A case study on the use of plant complexes

Published: April 2021

Information mutations are unintended changes in information that can lead to the establishment of poorly adapted cultural traits in local medical systems. The use of plant mixtures in local medical systems, such as “bottles and lickers” could it be an important model to understand this phenomena, since the variability of information associated an only one plant mixture is high and may lead to an higher occurrence of error in the social transmition. In this study, we sought to investigate whether the socioeconomic variables: gender, age, and education influences the amount of information mutations on the knowledge of plant mixtures. Data collection followed the ethical parameters for research with human beings and consisted of two different applications of semi-structured interviews to access and analyze the Information Unit (IU) in regards to the passivity of information mutation between the individual learner and the individual giving information. We obtained 141 types of plant mixtures mentioned in the study. When analyzing our variables, age and education influenced the number of mutations (p<0.0008), showing that younger individuals had information with more information mutations about plant mixtures, and less educated individuals had less information mutations than those with more education (p<0.006). Thus, we encourage ethnobotanical research in other regions of the country to contribute to the effectiveness of the information transmitted about medicinal plants in local medical systems.
Experimental determination and finite element analysis of coefficients of the multi-parameter Williams series expansion in the vicinity of the crack tip in linear elastic materials. Part II
Authors: Stepanova L. V
Published: April 2021

In this study coefficients of the multi-parameter Williams power series expansion for the stress field in the vicinity of the central crack in the rectangular plate and in the semi-circular notched disk under bending are obtained by the use of the finite element analysis. In SIMULIA Abaqus, the finite element analysis software, the numerical solutions for these two cracked geometries are found. The rectangular plate with the central crack has the geometry similar to the geometry used in the digital photoelasticity. Numerical simulations of the same cracked specimen as in the experimental photoelasticity method are performed. The numerical solutions obtained are utilized for the determination of the coefficients of the Williams series expansion. The higher-order coefficients are extracted from the finite element method calculations implemented in Simulia Abaqus software package and the outcomes are compared to experimental values. Determination of the coefficients of the terms of this series is performed using the least squares-based regression technique known as the over-deterministic method, for which stresses data obtained numerically in SIMULIA Abaqus software are taken as inputs. The plate with a small central crack has been considered either. This kind of the cracked specimen has been utilized for comparison of coefficients of the Williams series expansion obtained from the finite element analysis with the coefficients known from the theoretical solution based on the complex variable theory in plane elasticity. It is shown that the coefficients of the Williams series expansion match with good accuracy. The higher-order terms in the Williams series expansion for the semi-circular notch disk are found.

Published: April 2021

The paper contains necessary conditions allowing to reduce matrix tensors of pseudo-Riemannian spaces to special forms called semi-reducible, under assumption that the tensor defining tensor characteristic of semireducibility spaces, is idempotent.
The tensor characteristic is reduced to the spaces of constant curvature, Ricci-symmetric spaces and conformally flat pseudo-Riemannian spaces.

The obtained results can be applied for construction of examples of spaces belonging to special types of pseudo-Riemannian spaces.

The research is carried out locally in tensor shape, without limitations imposed on a sign of a metric.

Published: April 2021

ABSTRACT Background: Few studies have evaluated the incidence, predisposing factors and impact of healthcare-associated infections (HCAIs) in relation to outcomes among patients with status epilepticus (SE). Objective: To investigate the variables associated with development of HCAIs among patients with SE and the impact of factors relating to HCAIs on mortality at three months. Methods: This study was a retrospective analysis on our prospectively collected dataset, from November 2015 to January 2019. The sample included all consecutive patients diagnosed with SE who were treated at Hospital Eugenio Espejo during that period. In total, 74 patients were included. Clinical variables such as age, etiology of SE, Charlson comorbidity index (CCI), hospital length of stay, refractory SE (RSE) and outcomes were analyzed. Results: HCAIs were diagnosed in 38 patients (51.4%), with a preponderance of respiratory tract infection (19; 25.7%). Prolonged hospital length of stay (OR=1.09; 95%CI 1.03-1.15) and CCI≥2 (OR=5.50; 95%CI 1.37-22.10) were shown to be independent variables relating to HCAIs. HCAIs were associated with an increased risk of mortality at three months, according to Cox regression analysis (OR=2.23; 95%CI 1.08-4.58), and with infection caused by Gram-negative microorganisms (OR=3.17; 95%CI 1.20-8.39). Kaplan-Meier curve analysis demonstrated that HCAIs had a negative impact on the survival rate at three months (log rank=0.025). Conclusions: HCAIs are a common complication among Ecuadorian patients with SE and were related to a lower survival rate at three months. Prolonged hospital length of stay, RSE and CCI≥2 were associated with the risk of developing HCAIs.

ABSTRACT Background: Headache-Specific Locus of Control (LOC) refers to individuals’ beliefs about their control over the onset, course and consequences of headaches. LOC beliefs have been associated with depression, coping strategies, headache-related disability and treatment outcomes. Objective: To test the cross-cultural adaptation and psychometric properties of a Brazilian version of the Headache-Specific Locus of Control Scale (HSLC). Methods: One hundred and thirty-four migraine outpatients completed the HSLC and provided measurements of psychopathological symptoms, pain catastrophizing, depression, anxiety, quality of life and headache-related disability. Results: The three-factor structure of the HSLC (LOC-P, LOC-C and LOC-I) was confirmed in the Brazilian sample. The instrument showed good internal consistency, with Cronbach's α of 0.77 for total HSLC and 0.70, 0.83 and 0.87, for LOC-P, LOC-C and LOC-I, respectively. LOC-C correlated with headache frequency and headache intensity. Along with headache intensity, depression and pain catastrophizing, LOC-I accounted for 45% of the variance (adjusted R2=0.45; F=12.97; p<0.01) in headache-related disability. Conclusions: The Brazilian version of the HSLC is a valid and reliable measure of headache-specific LOC beliefs. It is important to consider the balance between the three LOCs for each individual, instead of interpreting them separately.

ABSTRACT Background: In recent years there has been an increasing number of elderly people who care for another elderly person in the same household. These elderly people are more susceptible to overload and the presence of chronic pain, while pain can negatively influence cognitive variables. Objective: To compare the performance and cognitive processing of elderly caregivers and non-caregivers with and without chronic pain. Methods: This was a cross-sectional study carried out among 149 elderly people divided into four groups that were matched according to sex, age and schooling. The tests used were a numerical pain assessment scale, the Brief Cognitive Screening Battery (BCSB), Addenbrooke’s Cognitive Examination (ACER-R) and cognitive processing through event-related potentials (P300). Results: Statistically significant differences between participants with and without chronic pain were found with regard to attention/orientation (p=0.045) and visual-spatial skills (p=0.017), and in the total score (p=0.033). In the pain-free group, the caregivers showed better results than the non-caregivers. There were no effects between subjects or interactions (caregiving and pain factors) either on P300 amplitude or on P300 latency. Conclusion: In general, it was observed that pain-free individuals presented better performance. No relationship was observed between the factors care and pain regarding cognitive performance.

ABSTRACT Background: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined. Objectives: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis. Methods: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects. Results: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001). Conclusion: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

RESUMO: O artigo analisa o Tempo de Permanência na Escola (TPE) dos estudantes-atletas de futebol a partir da adaptação do modelo de cálculo proposto por Neri (2009). A variável tempo nos serviu para verificar o investimento do estudante-atleta na dupla carreira esportiva. Realizamos a pesquisa com 62 estudantes-atletas residentes no alojamento de um tradicional clube de futebol do Rio de Janeiro, cuja faixa etária está entre 14 e 17 anos. Para o levantamento de dados, foi utilizado um questionário estruturado e, para a análise, o modelo metodológico para o cálculo do TPE de estudantes-atletas. Observamos que estudos na área da educação e da educação física insinuam que o tempo de dedicação aos treinamentos esportivos concorrem com o tempo escolar e o prejudicam. Os resultados do nosso estudo sugerem que o problema da redução do TPE dos estudantes-atletas é provocado pelo descumprimento e pela flexibilização das normas escolares por parte da própria instituição escolar.
STREET-LEVEL BUREAUCRACY AND PUBLIC POLICIES: ANALYZING EDUCATIONAL POLICY IMPLEMENTATION FROM THE PERSPECTIVE OF SCHOOLS AND TEACHERS

Published: April 2021

ABSTRACT This paper analyzes the implementation of educational policies and the roles of school professionals considering the street-level bureaucracy theory (LIPSKY, 1980). This study assumes that educational reforms elect schools as planning and administration centers, making them and the professionals working there responsible for new attributions which are motivated by improved autonomy, in addition to administrative and educational decentralization. In these contexts, which are marked by schools’ increasing empowerment, the discretionary power exercised by its professionals (teachers, principals, coordinators, among others) is a key element to understanding the availability and implementation of programs and their ability to either influence or change the design of educational policies on a local level. This perspective emphasizes the importance of considering those closer to actions deriving from such policies, that is, the actors who see the bottom-up process because they are in the lower end. According to Lipsky (1980), these are the so-called local policy agents or street-level public agents. As for schools, we understand that to enforce a certain policy, factors such as interpersonal influence, commitments, and informal negotiations are as important as formal processes and regulations. Finally, this study attempts to prove the impacts and contours assumed by changes in school dynamics in terms of translating local educational policies.

RESUMO: O debate sobre as Tecnologias Sociais tem chegado a vários setores da sociedade, incluindo as instituições de ensino e pesquisa. Entretanto, ainda são poucos os projetos desse tipo produzidos nesses contextos e há carência na formação voltada para o desenvolvimento prático desse tipo de intervenção em comunidades brasileiras, o que dificulta sua viabilização, sobretudo em contextos educacionais, nos quais é preciso planejar e avaliar as ações educativas. Neste artigo, as TS são analisadas sob a perspectiva de sua aplicação à Educação Profissional e Tecnológica, especificamente nos Institutos Federais. São apresentados os resultados de um Estudo de Mapeamento Sistemático que selecionou estudos primários indicativos de aspectos metodológicos de desenvolvimento de projetos concretos de TS implementados em comunidades brasileiras. Ao final do mapeamento, 186 artigos, i.e. apenas 5,9% da amostra analisada, evidenciaram a metodologia aplicada ao desenvolvimento da TS. A partir da discussão dos resultados do mapeamento, foi conduzida uma Análise Temática para analisar qualitativamente padrões significativos do conjunto de dados que revelassem métodos e processos de produção de TS, no sentido de sistematizar um produto educacional de formação docente. O produto propôs trilhas colaborativas de desenvolvimento de TS adequadas às especificidades locais com a meta de elaborar um projeto em TS aplicável a seus Campi de atuação no Instituto Federal de Sergipe (IFS). Como forma de aplicação e avaliação do produto educacional, foi desenvolvido um Estudo de Caso com docentes e técnicos do IFS - Campus Lagarto que resultou em bons prognósticos de aplicação mais ampla.

Abstract Food insecurity is a complex phenomenon that affects the health and wellbeing of vulnerable families. The aim of this study was to investigate the relationship between household food insecurity, dental caries, oral health-related quality of life, and social determinants of health among Indigenous adults. A cross-sectional study was conducted among Kaingang adults aged 35-44 years old from the Guarita Indigenous Land, Brazil. Food insecurity was assessed through the EBIA scale. Dental caries was assessed using the DMFT index. Participants answered the OHIP-14 questionnaire and a structured interview. Descriptive and multivariate analyzes using Poisson regression models were performed. The final sample included 107 adults from 97 households. Approximately 95% lived in food insecure families. Severe food insecurity was present in 58% of the households. The phenomenon was associated to the Bolsa Família benefit, household size, and greater perception of oral health impacts on quality of life. The high number of families affected by food insecurity reveals the social vulnerability of the Kaingang people. Food insecurity in Kaingangs adults is associated to oral health perception and social determinants of health.

Resumo O objetivo deste artigo é medir o impacto da formação em medicina de família e comunidade no percentual de encaminhamentos a partir da atenção primária. Estudo transversal descritivo de 375.645 consultas e 34.776 encaminhamentos realizadas por 123 médicos da atenção primária no ano de 2016 relacionando o percentual de encaminhamentos com características dos médicos (sexo, idade, formação em MFC), dos pacientes (sexo e idade) e do serviço (população pelo IBGE e população ativa). A formação em MFC por meio de residência médica apresentou uma significativa redução no percentual de encaminhamentos a partir da atenção primária (2,86%), IC:(1,55;4,17), p < 0,0001. Essa redução manteve-se na análise multivariada mesmo ajustando-se para todas as possíveis variáveis confundidoras. Não houve diferença na comparação do percentual de encaminhamentos entre médicos sem formação em MFC e médicos com titulação em MFC. Na análise das especialidades para as quais foram realizados os encaminhamentos, os médicos com residência em MFC encaminharam menos para ginecologia, psiquiatria e pediatria e mais para oftalmologia. O estudo mostrou que a formação em MFC por meio de residência médica acarretou significativa redução no percentual de encaminhamentos a partir da atenção primária.

Resumo O objetivo deste artigo é analisar a prevalência de polifarmácia e de polifarmácia excessiva, bem como seus fatores associados, entre idosos atendidos em duas Unidades Básicas de Saúde de Belo Horizonte-MG. Foi conduzido um estudo observacional transversal, realizado por meio de informações resultantes de uma entrevista estruturada ao paciente. Foram analisadas as associações individuais de cada variável explicativa com a polifarmácia e polifarmácia excessiva. Para as variáveis que apresentaram associação significativa com polifarmácia, foi realizada análise multivariada por meio do modelo de regressão logística. Os idosos utilizavam, em média, 5,2 fármacos. A prevalência de polifarmácia foi de 57,7% e de polifarmácia excessiva foi de 4,8%. Na análise univariada, mostraram-se associadas à polifarmácia as condições idade ≤ 70 anos, escolaridade > 8 anos, presença de mais de três doenças e presença de sintomas de depressão. Para polifarmácia excessiva, mostraram-se associadas as condições presença de mais de três doenças, autopercepção da saúde negativa e dependência parcial nas atividades instrumentais de vida diária. No modelo multivariado final para polifarmácia, permaneceram as variáveis idade ≤ 70 anos e presença de mais de três doenças.

Resumo Em um contexto de restrição orçamentária e de medidas de austeridade fiscal, discutir aspectos relacionados à gestão eficiente dos recursos públicos é um desafio. O objetivo deste estudo foi avaliar a eficiência técnica de municípios catarinenses nos gastos públicos com saúde e sua relação com as condições para a gestão em saúde nos anos de 2009 e 2015. Para medir a eficiência, optou-se pela Análise Envoltória de Dados. O Índice G foi empregado para analisar a autocorrelação espacial da eficiência. Para a avaliação das condições para a gestão em saúde, adotou-se o modelo proposto por Calvo et al. Do total de municípios analisados, 35,5% e 29% foram considerados eficientes, respectivamente para os anos de 2009 e 2015. Os resultados sugerem não haver associação entre as condições para a gestão em saúde e a eficiência técnica no estado de Santa Catarina. O estudo revelou a necessidade de se avançar na busca por melhores resultados de eficiência em Santa Catarina, devendo ser considerada a distribuição espacial destes resultados sobre o território, com enfoque sobre os clusters de ineficiência que podem explicar o fraco desempenho em saúde de algumas regiões do estado.
